    Purpose: To report 15-year biochemical relapse-free survival (BRFS), cause-specific survival (CSS), and overall survival (OS) outcomes of patients treated with I 125 brachytherapy monotherapy for clinically localized prostate cancer early in the Seattle experience. Methods and Materials: Two hundred fifteen patients with clinically localized prostate cancer were consecutively treated from 1988 to 1992 with I 125 monotherapy. They were prospectively followed as a tight cohort. They were evaluated for BRFS, CSS, and OS. Multivariate analysis was used to evaluate outcomes by pretreatment clinical prognostic factors. BRFS was analyzed by the Phoenix (nadir + 2 ng/mL) definition. CSS and OS were evaluated by chart review, death certificates, and referring physician follow-up notes. Gleason scoring was performed by general pathologists at a community hospital in Seattle. Time to biochemical failure (BF) was calculated and compared by Kaplan-Meier plots. Results: Fifteen-year BRFS for the entire cohort was 80.4%. BRFS by D'Amico risk group classification cohort analysis was 85.9%, 79.9%, and 62.2% for low, intermediate, and high-risk patients, respectively. Follow-up ranged from 3.6 to 18.4 years; median follow-up was 15.4 years for biochemically free of disease patients. Overall median follow-up was 11.7 years. The median time to BF in those who failed was 5.1 years. CSS was 84%. OS was 37.1%. Average age at time of treatment was 70 years. There was no significant difference in BRFS between low and intermediate risk groups. Conclusion: I 125 monotherapy results in excellent 15-year BRFS and CSS, especially when taking into account the era of treatment effect.

    To describe the results in terms of audiometric relapse-free survival and relapse rate in immunomediated hearing loss patients treated exclusively with corticosteroids. Retrospective study of patients with audiometric relapses, monitored from 1995 to 2014, in two centres of the Community of Madrid. We evaluated 31 patients with a mean age of 48.52 years (14.67 SD), of which 61.3% were women. Most hearing loss was fluctuating (48.4%). Only 16.1% of patients had systemic autoimmune disease. There is a moderate positive correlation between the sex variable and the systemic involvement variable (Spearman's correlation coefficient=0.356): specifically, between being female and systemic disease. The relative incidence rate of relapse in the first year was 2.01 relapses/year with a 95% CI (1.32 to 2.92). The mean survival time of the event (audiometric relapse) was 5.25 months (SD 0.756). With multivariate analysis, the only variable that achieved statistical significance was age, with a hazard ratio of 1.032 (95% CI; 1.001-1.063, P=.043). Immune-mediated disease of the inner ear is a chronic disease with relapses. Half of the patients with immunomediated hearing loss treated exclusively with corticosteroids relapse before 6 months of follow-up. In addition, if a patient has not relapsed, they are more likely to relapse as each year passes. Analysis of the of audiometric relapse- free survival will enable the effect of future treatments to be compared and their capacity to reduce the rhythm of relapses.

    Umbilical cord blood stem cell transplants are commonly used in adults lacking HLA-identical donors. Delays in hematopoietic recovery contribute to mortality and morbidity. To hasten recovery, we used co-infusion of progenitor cells from a partially matched related donor and from an umbilical cord blood graft (haplo-cord transplant). Here we compared the outcomes of haplo-cord and double-cord transplants. A total of 97 adults underwent reduced intensity conditioning followed by haplo-cord transplant and 193 patients received reduced intensity conditioning followed by double umbilical cord blood transplantation. Patients in the haplo-cord group were more often from minority groups and had more advanced malignancy. Haplo-cord recipients received fludarabine-melphalan-anti-thymocyte globulin. Double umbilical cord blood recipients received fludarabine-cyclophosphamide and low-dose total body irradiation. In a multivariate analysis, haplo-cord had faster neutrophil (HR=1.42, P=0.007) and platelet (HR=2.54, Pdisease (HR=0.26, Pdisease (HR=0.06, Pdisease-free, relapse-free survival was superior with haplo-cord (HR 0.63, P=0.002) but not overall survival (HR=0.97, P=0.85). Haplo-cord transplantation using fludarabine-melphalan-thymoglobulin conditioning hastens hematopoietic recovery with a lower risk of relapse relative to double umbilical cord blood transplantation using the commonly used fludarabine-cyclophosphamide-low-dose total body irradiation conditioning. Graft-versus-host disease-free and relapse-free survival is significantly improved. Haplo-cord is a readily available graft source that improves outcomes and access to transplant for those lacking HLA-matched donors.

    Full Text Available PURPOSEProstate stereotactic body radiotherapy (SBRT may substantially recapitulate the dose distribution of high-dose-rate (HDR brachytherapy, representing an externally delivered Virtual HDR treatment method. Herein we present 5-year outcomes from a cohort of consecutively treated Virtual HDR SBRT prostate cancer patients.METHODSSeventy-nine patients were treated from 2006 - 2009, 40 low-risk and 39 intermediate-risk, under IRB-approved clinical trial, to 38 Gy in 4 fractions. The planning target volume (PTV included prostate plus a 2-mm volume expansion in all directions, with selective use of a 5-mm prostate-to-PTV expansion and proximal seminal vesicle coverage in intermediate-risk patients, to better cover potential extraprostatic disease; rectal PTV margin reduced to zero in all cases. The prescription dose covered > 95% of the PTV (V100 >= 95%, with a minimum 150% PTV dose escalation to create HDR-like PTV dose distribution.RESULTSMedian pre-SBRT PSA level of 5.6 ng/mL decreased to 0.05 ng/mL 5 years out and 0.02 ng/mL 6 years out. At least one PSA bounce was seen in 55 patients (70% but only 3 of them subsequently relapsed, Biochemical-relapse-free survival was 100% and 92% for low-risk and intermediate-risk patients, respectively, by ASTRO definition (98% and 92% by Phoenix definition. Local relapse did not occur, distant metastasis-free survival was 100% and 95% by risk-group, and disease-specific survival was 100%. Acute and late grade 2 GU toxicity incidence was 10% and 9%, respectively; with 6% late grade 3 GU toxicity. Acute urinary retention did not occur. Acute and late grade 2 GI toxicity was 0% and 1%, respectively, with no grade 3 or higher toxicity. Of patients potent pre-SBRT, 65% remained so at 5 years.CONCLUSIONSVirtual HDR prostate SBRT creates a very low PSA nadir, a high rate of 5-year disease-free survival and an acceptable toxicity incidence, with results closely resembling those reported post-HDR brachytherapy.

    Metaplastic carcinoma of the breast is a rare tumor. The appearance of unexpected mesenchymal elements within the epithelial tumors is the squamous metaplasia. These tumors have a different clinical behaviour that classical breast carcinoma. We present a case of metaplastic mammary carcinoma with multiple relapses treated with a combination of chemotherapy and radiotherapy. The use of chemotherapy after local treatment has enhanced the relapse-free survival. The combined treatment modality seems to produce some benefit in the management of the local relapses of this neoplasms

    Purpose: Vascular endothelial growth factor (VEGF) is an important protein involved in the process of angiogenesis that has been found to correlate with relapse-free and overall survival in breast cancer, predominantly in locally advanced and metastatic disease. A paucity of data is available on the prognostic implications of VEGF in early-stage breast cancer; specifically, its prognostic value for local relapse after breast-conserving therapy (BCT) is largely unknown. The purpose of our study was to assess VEGF expression in a cohort of early-stage breast cancer patients treated with BCT and to correlate the clinical and pathologic features and outcomes with overexpression of VEGF. Methods and Materials: After obtaining institutional review board approval, the paraffin specimens of 368 patients with early-stage breast cancer treated with BCT between 1975 and 2005 were constructed into tissue microarrays with twofold redundancy. The tissue microarrays were stained for VEGF and read by a trained pathologist, who was unaware of the clinical details, as positive or negative according the standard guidelines. The clinical and pathologic data, long-term outcomes, and results of VEGF staining were analyzed. Results: The median follow-up for the entire cohort was 6.5 years. VEGF expression was positive in 56 (15%) of the 368 patients. Although VEGF expression did not correlate with age at diagnosis, tumor size, nodal status, histologic type, family history, estrogen receptor/progesterone receptor status, or HER-2 status, a trend was seen toward increased VEGF expression in the black cohort (26% black vs. 13% white, p = .068). Within the margin-negative cohort, VEGF did not predict for local relapse-free survival (RFS) (96% vs. 95%), nodal RFS (100% vs. 100%), distant metastasis-free survival (91% vs. 92%), overall survival (92% vs. 97%), respectively (all p >.05). Subset analysis revealed that VEGF was highly predictive of local RFS in node-positive, margin

    Riboflavin is an essential micronutrient for normal cellular activity, and deficiency may result in disease, such as cancer. We performed a case-control study to explore the association of riboflavin levels with risk and prognosis of esophageal squamous cell carcinoma (ESCC). Plasma riboflavin levels, as measured by enzyme-linked immunosorbent assay (ELISA), in ESCC patients were significantly lower than in those of healthy controls (7.04 ± 6.34 ng/ml vs. 9.32 ± 12.40 ng/ml; P riboflavin level and risk of ESCC (odds ratio (OR) = 0.97, 95% confidence interval (CI) = 0.95-0.99, P =  0.02). The 5-year relapse-free and overall survival rates were significantly lower when riboflavin levels were ≤0.8 ng/ml than >0.8 ng/ml (relapse-free survival rate: 29.4% vs. 54.8%; overall survival rate: 28.6% vs. 55.6%). Plasma riboflavin level was an independent protective factor for both relapse-free (hazard ratio (HR) = 0.325, 95% CI = 0.161-0.657, P = 0.002) and overall survival of ESCC patients (HR = 0.382, 95% CI = 0.190-0.768, P = 0.007). In conclusion, plasma riboflavin levels are significantly related to risk and prognosis of ESCC patients, suggesting that moderate supplementation of riboflavin will decrease risk and prevent recurrence of ESCC and also improve prognosis of ESCC patients.

    The aim of this study was to develop a new composite endpoint that accurately reflects the long-term success of allogeneic hematopoietic stem cell transplantation (allo-HSCT), as the conventional graft-versus-host disease (GVHD)-free, relapse-free survival (GRFS) overestimates the impact of GVHD. First, we validated current GRFS (cGRFS), which recently was proposed as a more accurate endpoint of long-term transplant success. cGRFS was defined as survival without disease relapse/progression or active chronic GVHD at a given time after allo-HSCT, calculated using 2 distinct methods: a linear combination of a Kaplan-Meier estimates approach and a multistate modelling approach. Next, we developed a new composite endpoint, refractory GRFS (rGRFS). rGRFS was calculated similarly to conventional GRFS treating grade III to IV acute GVHD, chronic GVHD requiring systemic treatment, and disease relapse/progression as events, except that GVHD that resolved and did not require systemic treatment at the last evaluation was excluded as an event in rGRFS. The 2 cGRFS curves obtained using 2 different approaches were superimposed and both were superior to that of conventional GRFS, reflecting the proportion of patients with resolved chronic GVHD. Finally, the curves of cGRFS and rGRFS overlapped after the first 2 years of post-transplant follow-up. These results suggest that cGRFS and rGRFS more accurately reflect transplant success than conventional GRFS. Especially, rGRFS can be more easily calculated than cGRFS and analyzed with widely used statistical approaches, whereas cGRFS more accurately represents the burden of GVHD-related morbidity in the first 2 years after transplantation.

    Objective: The ARO 96-02 trial primarily compared wait-and-see (WS, arm A) with adjuvant radiation therapy (ART, arm B) in prostate cancer patients who achieved an undetectable prostate-specific antigen (PSA) after radical prostatectomy (RP). Here, we report the outcome with up to 12 years of follow-up of patients who retained a post-RP detectable PSA and received salvage radiation therapy (SRT, arm C). Methods and Materials: For the study, 388 patients with pT3-4pN0 prostate cancer with positive or negative surgical margins were recruited. After RP, 307 men achieved an undetectable PSA (arms A + B). In 78 patients the PSA remained above thresholds (median 0.6, range 0.05-5.6 ng/mL). Of the latter, 74 consented to receive 66 Gy to the prostate bed, and SRT was applied at a median of 86 days after RP. Clinical relapse-free survival, metastasis-free survival, and overall survival were determined by the Kaplan-Meier method. Results: Patients with persisting PSA after RP had higher preoperative PSA values, higher tumor stages, higher Gleason scores, and more positive surgical margins than did patients in arms A + B. For the 74 patients, the 10-year clinical relapse-free survival rate was 63%. Forty-three men had hormone therapy; 12 experienced distant metastases; 23 patients died. Compared with men who did achieve an undetectable PSA, the arm-C patients fared significantly worse, with a 10-year metastasis-free survival of 67% versus 83% and overall survival of 68% versus 84%, respectively. In Cox regression analysis, Gleason score ≥8 (hazard ratio [HR] 2.8), pT ≥ 3c (HR 2.4), and extraprostatic extension ≥2 mm (HR 3.6) were unfavorable risk factors of progression. Conclusions: A persisting PSA after prostatectomy seems to be an important prognosticator of clinical progression for pT3 tumors. It correlates with a higher rate of distant metastases and with worse overall survival. A larger prospective study is required to determine which patient subgroups

    The aim of the study was to evaluate the rate of relapse as well as disease-free, overall, and disease-specific survival in women with borderline ovarian tumour (BOT). Furthermore, the study aims to identify the clinical parameters correlated to relapse. National clinical data of women diagnosed with BOT from January 2005 to January 2013 constituted the basis for our study population. The prognostic influence of clinical variables was evaluated using univariate and multivariate analyses. A total of 1143 women were eligible for analysis, with 87.9% in FIGO stage I and 12.1% in FIGO stages II-IV. Relapse of BOT was detected in 3.7%, hereof 40.5% with malignant transformation. The five-year disease-free survival was 97.6% in FIGO stage I and 87.3% in FIGO stages II-IV. Younger age, laparoscopic surgical approach, fertility sparing surgery, FIGO stages II-IV, bilateral tumour presence, serous histology, implants and microinvasion of the tumour were significantly associated with relapse in univariate analyses. The overall five-year survival rate was 92.2% in FIGO stage I and 89.0% in FIGO stages II-IV. Out of 77 deaths in total, only seven women died from BOT. A general favourable prognosis in women with BOT was confirmed in our study. Our findings indicate that systematic, long-term follow-up does not seem necessary in women treated for FIGO stage IA BOT with no residual disease or microinvasion. Copyright © 2016 Elsevier Inc.

    Abstract Controversy remains regarding whether preoperative chemoradiation protocol should be applied uniformly to all rectal cancer patients regardless of tumor height. This pooled analysis was designed to evaluate whether preoperative chemoradiation can be safely omitted in higher rectal cancer. An international consortium of 7 institutions was established. A review of the database that was collected from January 2004 to May 2008 identified a series of 2102 patients with stage II/III rectal or sigmoid cancer (control arm) without concurrent chemoradiation. Data regarding patient demographics, recurrence pattern, and oncological outcomes were analyzed. The primary end point was the 5-year local recurrence rate. The local relapse rate of the sigmoid colon cancer (SC) and upper rectal cancer (UR) cohorts was significantly lower than that of the mid/low rectal cancer group (M-LR), with 5-year estimates of 2.5% for the SC group, 3.5% for the UR group, and 11.1% for the M-LR group, respectively. A multivariate analysis showed that tumor depth, nodal metastasis, venous invasion, and lower tumor level were strongly associated with local recurrence. The cumulative incidence rate of local failure was 90.6%, 92.5%, and 94.4% for tumors located within 5, 7, and 9 cm from the anal verge, respectively. Routine use of preoperative chemoradiation for stage II/III rectal tumors located more than 8 to 9 cm above the anal verge would be excessive. The integration of a more individualized approach focused on systemic control is warranted to improve survival in patients with upper rectal cancer. PMID:27258487

    Purpose: The aim of the present analysis is to determine the long-term results in terms of breast relapse and specific survival in patients treated with conserving surgery and adjuvant treatment for early breast cancer. Methods: From January 1980 to December 2001, 3834 patients with pT1-T2 breast cancer were treated consecutively at the University of Florence. The median age of the patient population was 55 years (range 30-80). All patients were followed for a median of 7.4 years (range 0.6 year to 22.5 years). The crude probability of survival (or local recurrence) was estimated by using Kaplan-Meier method, and survival (or local recurrence) comparisons were carried out using Cox proportional hazard regression models. Results: The Cox regression model by stepwise selection showed some parameters, such as chemotherapy (HR 1.53; CI 1.19-1.95), pT status (HR 1.62, CI 1.31-2.01), positive axillary lymph nodes (HR 1.92, CI 1.66-2.22), and local recurrence (HR 4.58; CI 3.66-5.73), as independent prognostic factors for breast cancer death. Moreover, we found lower rate survival among patients treated before 1991 in comparison to women treated after 1991 (p = 0.0001) probably due to inadequate treatment. For local disease free survival, age at presentation (HR 0.47; CI 0.35-0.63), use of tamoxifen (HR 0.42; CI 0.25-0.71), surgical margins (HR 2.00; CI 1.21-3.30), and chemotherapy (HR 0.53; CI 0.31-0.91) emerged by multivariate analyses as significant breast relapse predictors. Conclusion: In our experience breast conserving surgery followed by adjuvant radiotherapy treatment gives high rates of local control in women with early breast cancer. The use of routinely adjuvant chemotherapy and hormone therapy lowered the local recurrence and probably the modification of therapeutic approach in the last decades also improved the specific survival

    To correlate the clinical features of women presenting with locally advanced breast cancer with event-free survival (EFS) and overall survival (OS) and to evaluate the patterns of relapse. Methods: A total of 200 patients presenting consecutively over 9 years with Stage III breast cancer were evaluated for age, socio-economic status (SES), tumour size and grade, number of involved lymph nodes, stage III sub-categories, estrogen and progesterone receptor (ER/PR) status, treatment profiles and responses, and sites of relapse. EFS and OS at 5 and 10 years were calculated. Results: Median age was 45 years. Poorly differentiated tumours were found in 127 patients, while 128 had larger tumours (T3 and T4). Eighty women had extensive nodal involvement (N2 and N3), and 86 had Stage IIIA tumours. Chemotherapy was given to 44 patients before surgery and one of these patients achieved pathological complete response. At 5 and 10 years, EFS was 25% and 7%, and OS was 52% and 31%, respectively. By Cox regression analysis, significant predictors of EFS included tumour size (95% CI 1.14-1.72), nodal involvement (95% CI 1.06-1.59) and ER/PR positive tumours (95% CI 1.08-2.29). Predictors of OS included nodal involvement (95% CI 0.98-3.3) and ER/PR positive tumours (95% CI 1.08-2.29). No patient in stage IIIC was alive at 10 years. Loco-regional disease was the most common site of relapse (28.5%). Conclusions: Locally advance breast cancer at our centre is associated with poor survival, and most patients relapsed by 5 years.

    A wide variety of endogenous retroviral sequences has been demonstrated in the human genome so far, divided into several different families according to the sequence homology to viral strains. While increased expression of human endogenous retrovirus (HERV) elements has already been linked to unfavorable prognosis in hepatocellular carcinoma, breast cancer, and ovarian carcinoma yet less is known about the impact of the expression of different HERV elements on sarcomagenesis in general as well as the outcome of soft tissue sarcoma (STS) patients. Therefore, in this study the association between expression of HERV-K and HERV-F and the clinicopathological characteristics in a cohort of STSs as well as the patients' prognosis was evaluated. HERV-K and HERV-F expression was assessed by quantitative real-time PCR in 120 patient specimens. HERV-K and HERV-F expression was significantly correlated ( r S = 0.5; p = 6.4 × 10 -9 ; Spearman's rank bivariate correlation). Also, tumor diameter exhibited a significant negative association to HERV-K and HERV-F expression. Levels of several hypoxia-related RNAs like HIF-1α and miR-210 showed a significant positive correlation with both HERV-K and HERV-F expression. Although in survival analyses no impact of HERV expression on disease-specific survival could be detected, patients with elevated HERV-K expression had a significantly shorter relapse-free survival ( p = 0.014, log-rank analysis). In conclusion, we provide evidence for the first time that the increased expression of HERV-K in tumors is associated with STS patients' prognosis.

    Full Text Available BACKGROUND: Despite advances in the treatment of acute leukemia, many patients need to undergo hematopoietic stem cell transplantation. Recent studies show that early lymphocyte recovery may be a predictor of relapse and survival in these patients. OBJECTIVE: To analyze the influence of lymphocyte recovery on Days +30 and +100 post-transplant on the occurrence of relapse and survival. METHODS: A descriptive, retrospective study was performed of 137 under 21-year-old patients who were submitted to hematopoietic stem cell transplantation for acute leukemia between 1995 and 2008. A lymphocyte count 0.3 x 10(9/L were considered adequate. Lymphocyte recovery was also analyzed on Day +100 with < 0.75 x 10(9/Land < 0.75 x 10(9/L being considered inadequate and adequate lymphocyte recovery, respectively. RESULTS: There was no significant difference in the occurrence of relapse between patients with inadequate and adequate lymphocyte recovery on Day +30 post-transplant. However, the transplant-related mortality was significantly higher in patients with inadequate recovery on Day +30. Patients with inadequate lymphocyte recovery on Day +30 had worse overall survival and relapse-free survival than patients with adequate recovery. There was no significant difference in the occurrence of infections and acute or chronic graft-versus-host disease. Patients with inadequate lymphocyte recovery on Day +100 had worse overall survival and relapse-free survival and a higher cumulative incidence of relapse. CONCLUSION: The evaluation of lymphocyte recovery on Day +30 is not a good predictor of relapse after transplant however patients with inadequate lymphocyte recovery had worse overall survival and relapse-free survival. Inadequate lymphocyte recovery on Day +100 is correlated with higher cumulative relapse as well as lower overall survival and relapse-free survival.

    Patients with leukemia relapsing after allogeneic hematopoietic SCT have a dismal prognosis. A second SCT offers a further opportunity for cure, but has a high rate of treatment failure. To determine the utility of this option, we analyzed 59 consecutive patients relapsing after a myeloablative HLA-matched sibling T cell-depleted (TCD) SCT. Twenty-five patients (13 relapsing within 6 months and 12 relapsing between 6 and 170 months after the first SCT) received a T-replete second SCT. Thirty-eight patients relapsing early had a shorter survival than the 21 patients relapsing later (median 96 vs 298 days, P=0.0002). In patients relapsing early, the second SCT did not improve OS compared with patients receiving non-SCT treatments (median survival 109 vs 80 days, P=0.41). In patients relapsing late, despite an early trend in favor of second SCT, survival was comparable for patients receiving a second SCT compared with non retransplanted patients (median survival 363.5 vs 162 days, P=0.49). Disappointingly, our results do not demonstrate an important survival benefit for a second T-replete allogeneic SCT to treat relapse following a TCD SCT.

    To investigate the role of neutrophil-to-lymphocyte ratio as a prognostic indicator in patients with localized clear cell renal cell carcinoma treated with radiofrequency ablation. We retrospectively analyzed data from patients with renal cell carcinoma who underwent radiofrequency ablation from 2006 to 2013. The Kaplan-Meier method was used to generate the survival curves according to different categories of neutrophil-to-lymphocyte ratio. Relationships between preoperative neutrophil-to-lymphocyte ratio or the change of neutrophil-to-lymphocyte ratio and survival were evaluated with multivariable Cox proportional hazards regression analysis. A propensity score matching analysis was carried out to avoid confounding bias. A total of 185 patients were included in present study. When stratified by preoperative neutrophil-to-lymphocyte ratio cutoff value of 2.79, 5-year recurrence-free survival, 5-year disease-free survival, and 5-year overall survival rates of neutrophil-to-lymphocyte ratio analysis, 5-year recurrence-free survival, 5-year disease-free survival, and 5-year overall survival rates of neutrophil-to-lymphocyte ratio ratio with the change of neutrophil-to-lymphocyte ratio, patients with both preoperative neutrophil-to-lymphocyte ratio ≥2.79 and the change of neutrophil-to-lymphocyte ratio ≥0.40 had the worst disease-free survival. Results of multivariable analysis showed that preoperative neutrophil-to-lymphocyte ratio and the change of neutrophil-to-lymphocyte ratio correlated with cancer relapse remarkably. High preoperative neutrophil-to-lymphocyte ratio and elevated postoperative neutrophil-to-lymphocyte ratio are associated with significant increase in risk of local recurrence as well as distant metastasis. The combination of neutrophil-to-lymphocyte ratio with the other prognostic indicators can be applied in the evaluation of relapse risk in patients with clear cell renal cell carcinoma after radiofrequency ablation.

    Purpose: To determine the rates of survival and disease control by TNM and MAC stage in three randomized North American rectal adjuvant studies. Materials and Methods: Data were merged from 2551 eligible patients on NCCTG 79-47-51 (n=200), NCCTG 86-47-51 (n=656), and INT 114 (n=1695). All patients received postoperative radiation, and 96% were randomized to receive concomitant and maintenance chemotherapy. Five-year follow-up was available in 94% of patients and 7-yr follow-up in 84%. Kaplan-Meier curves were used to estimate the distribution of overall survival (OS) and disease-free survival (DFS), and p values were derived using the log-rank test. Time to local and distant relapse was estimated using cumulative incidence methodology. Analyses were adjusted for treatment effect using Cox proportional hazards models. Results: OS and DFS were dependent on both TN stage and NT stage (N substage within T stage and T substage within N stage). Even among N2 patients (4 or more LN+), T stage influenced 5-yr OS (T1-2, 69%; T3, 48%; T4, 38%). Three risk groups of patients were defined: (1) intermediate: T3N0, T1-2N1; (2) moderately high: T4N0, T1-2N2, T3N1; and (3) high: T3N2, T4N1, T4N2. For Group 1, 5-yr OS was 74% and 81%, and 5-yr DFS was 66% and 74%. For Group 2, 5-yr OS ranged from 61% to 69%, and for Group 3, OS ranged from 33% to 48%. Cumulative incidence rates of local relapse and distant metastases revealed similar differences by TN and NT stage, as seen in the survival analyses. Conclusion: Patients with a single high-risk factor of either extension beyond the rectal wall (T3N0) or nodal involvement (T1-2N1) have improved OS, DFS, and disease control when compared to those with both high risk factors. Different treatment strategies may be indicated for intermediate- (T3N0, T1-2N1) vs. moderately high or high-risk patients in view of differential survival and rates of relapse. For future trial design, it may be preferable to perform separate studies, or a planned

    Post-relapse survival (PRS) was evaluated in patients with Ewing sarcoma (EWS) enrolled in chemotherapy protocols based on the use of high-dose chemotherapy with busulfan and melfalan (HDT) as a first-line consolidation treatment in high-risk patients. EWS patients enrolled in ISG/SSG III and IV trials who relapsed after complete remission were included in the analysis. At recurrence, chemotherapy based on high-dose ifosfamide was foreseen, and patients who responded but had not received HDT underwent consolidation therapy with HDT. Data from 107 EWS patients were included in the analysis. Median time to recurrence (RFI) was 18 months, and 45 (42%) patients had multiple sites of recurrence. Patients who had previously been treated with HDT had a significantly (P = 0.02) shorter RFI and were less likely to achieve a second complete remission (CR2). CR2 status was achieved by 42 (39%) patients. Fifty patients received high-dose IFO (20 went to consolidation HDT). The 5-year PRS was 19% (95% CI 11 to 27%). With CR2, the 5-year PRS was 48% (95% CI 31 to 64%). Without CR2, median time to death was six months (range 1-45 months). According to the multivariate analysis, patients younger than 15 years, recurrence to the lung only, and RFI longer than 24 months significantly influenced the probability of PRS. Age, pattern of recurrence, RFI, and response to second-line chemotherapy influence post-relapse survival in patients with recurrent Ewing sarcoma. No survival advantage was observed from chemotherapy consolidation with HDT. © 2015 Wiley Periodicals, Inc.

    SLC52A3 was recently identified as a susceptibility gene for esophageal squamous cell carcinoma (ESCC). However, associations between the single nucleotide polymorphisms (SNPs) rs13042395 (C > T) and rs3746803 (G > A) in SLC52A3 and risk, tumor characteristics and survival of ESCC patients remain inconclusive and of unknown prognostic significance. Analyses of the association between SNPs in SLC52A3 and ESCC risk were performed on 479 ESCC cases, together with 479 controls, in a case-control study. Blood samples for cases and controls were collected and genotyped by real-time polymerase chain reaction (PCR) using TaqMan assays. Among the 479 ESCC cases, 343 cases with complete clinical data were used to investigate the association between SNPs and ESCC clinical characteristics; 288 cases with complete clinical data and 5-year follow-up data were used to analyze the association between SNPs and prognosis. Dual luciferase reporter assays and electrophoretic mobility shift assays (EMSAs) were used to investigate the biological function of rs13042395. No association was found between SLC52A3 rs3746803 and susceptibility, tumor characteristics or survival of ESCC patients. For rs13042395, TT genotype carriers were likely to have reduced lymph node metastasis (odds ratio (OR) = 0.55, 95 % confidence interval (CI), 0.31–0.98) and longer relapse-free survival time (P = 0.03) . Also, both rs13042395 (hazard ratio (HR) = 0.62, 95 % CI, 0.38–0.99) and regional lymph node metastasis (HR = 2.06, 95 % CI, 1.36–3.13 for N1 vs. N0; HR = 2.88, 95 % CI, 1.70–4.86 for N2 vs. N0; HR = 2.08, 95 % CI, 1.01–4.30 for N3 vs. N0) were independent factors affecting relapse-free survival for ESCC patients who underwent surgery. Dual luciferase reporter assays and EMSAs suggested that the CC genotype of rs13042395 enhanced SLC52A3 expression, probably via binding with specific transcription factors. The rs13042395 polymorphism in SLC52A3 is associated with regional lymph node

    Salvage therapy for residual or relapsed esophageal cancer after chemoradiotherapy (CRT) has not yet been established. We retrospectively evaluated relapse-free survival (RFS) after local recurrence following CRT and local control rate in patients who underwent argon plasma coagulation (APC). We reviewed the records of 14 patients who underwent APC after CRT for esophageal cancer at our department between 2001 and 2010 and analyzed overall survival (OS), 5-year survival rate, local control rate after APC and RFS-defined as the period between the end of CRT and the time when an iodine-negative area was found. Median OS and median RFS (mRFS) were 33 months and 6 months, respectively. The 5-year survival rate was 16.2%, and the local control rate after APC was 71.4% (10/14). RFS was significantly longer in the T1 group than in the T2/T3 group (p=0.03); the local control rate after APC did not significantly differ between groups. The high-dose (HD) radiation group had a significantly longer RFS and a tendency toward a higher local control rate after APC than did the standard-dose (SD) radiation group. APC was safe and resulted in a high rate of local control, regardless of T factor. HD radiation was associated with longer RFS and greater efficacy of APC treatment for local recurrence. (author)

    The concentration of capecitabine peaks at 1–2 hours after administration. We therefore assumed that proper timing of capecitabine administration and radiotherapy would maximize radiosensitization and influence survival among patients with locally advanced rectal cancer. We retrospectively reviewed 223 patients with locally advanced rectal cancer who underwent preoperative chemoradiation, followed by surgery from January 2002 to May 2006. All patients underwent pelvic radiotherapy (50 Gy/25 fractions) and received capecitabine twice daily at 12-hour intervals (1,650 mg/m2/day). Patients were divided into two groups according to the time interval between capecitabine intake and radiotherapy. Patients who took capecitabine 1 hour before radiotherapy were classified as Group A (n = 109); all others were classified as Group B (n = 114). The median follow-up period was 72 months (range, 7 to 149 months). Although Group A had a significantly higher rate of good responses (44% vs. 25%; p = 0.005), the 5-year local recurrence-free survival rates of 93% in Group A and 97% in Group B did not differ significantly (p = 0.519). The 5-year disease-free survival and overall survival rates were also comparable between the groups. Despite the better pathological response in Group A, the time interval between capecitabine and radiotherapy administration did not have a significant effect on survivals. Further evaluations are needed to clarify the interaction of these treatment modalities.

    Adjustment of mercaptopurine and methotrexate maintenance therapy of acute lymphoblastic leukaemia by leucocyte count is confounded by natural variations. Cytotoxicity is primarily mediated by DNA-incorporated thioguanine nucleotides (DNA-TGN). The aim of this study was to establish whether DNA-TGN concentrations in blood leucocytes during maintenance therapy are associated with relapse-free survival. In this substudy of the NOPHO ALL2008 phase 3 trial done in 23 hospitals in seven European countries (Denmark, Estonia, Finland, Iceland, Lithuania, Norway, and Sweden), we analysed data from centralised and blinded analyses of 6-mercaptopurine and methotrexate metabolites in blood samples from patients with non-high-risk childhood acute lymphoblastic leukaemia. Eligible patients were aged 1·0-17·9 years; had been diagnosed with non-high-risk precursor B-cell or T-cell leukaemia; had been treated according to the Nordic Society of Pediatric Hematology and Oncology ALL2008 protocol; and had reached maintenance therapy in first remission. Maintenance therapy was (mercaptopurine 75 mg/m 2 once per day and methotrexate 20 mg/m 2 once per week, targeted to a leucocyte count of 1·5-3·0 × 10 9 cells per L). We measured DNA-TGN and erythrocyte concentrations of TGN nucleotides, methylated mercaptopurine metabolites, and methotrexate polyglutamates. The primary objective was the association of DNA-TGN concentrations and 6-mercaptopurine and methotrexate metabolites with relapse-free survival. The secondary endpoint was the assessment of DNA-TGN concentration and 6-mercaptopurine and methotrexate metabolites during maintenance therapy phase 2. Between Nov 26, 2008 and June 14, 2016, 1509 patients from the NOPHO ALL2008 study were assessed for eligibility in the DNA-TGN substudy, of which 918 (89%) of 1026 eligible patients had at least one DNA-TGN measurement and were included in the analyses. Median follow-up was 4·6 years (IQR 3·1-6·1). Relapse-free survival was

    Purpose: Ki-67 is a human nuclear protein whose expression is strongly up-regulated in proliferating cells and can be used to determine the growth fraction in clonal cell populations. Although there are some data to suggest that Ki-67 overexpression may be prognostic for endpoints such as survival or postmastectomy recurrence, further elucidation of its prognostic significance is warranted. Specifically after breast conservation therapy (BCT) (defined in this setting as breast-conserving surgery and adjuvant radiation therapy), whether Ki-67 predicts for locoregional recurrence has not been investigated. The purpose of this study was to assess Ki-67 expression in a cohort of early-stage breast cancer patients to determine whether a significant independent association between Ki-67 and locoregional relapse exists. Methods and Materials: Ki-67 staining was conducted on a tissue microarray of 438 patients previously treated with BCT, and expression was analyzed with clinicopathologic features and outcomes from our database. Results: Ki-67 expression was more prevalent in black patients (37% of black patients vs 17% of white patients, P<.01), younger patients (27% of patients aged ≤50 years vs 15% of patients aged >50 years, P<.01), estrogen receptor (ER)–negative tumors (25% of ER-negative tumors vs 17% of ER-positive tumors, P=.04), human epidermal growth factor receptor 2 (HER2)/neu–positive tumors (35% of HER2-positive tumors vs 18% of HER2-negative tumors, P=.01), and larger tumors (26% of T2 tumors vs 16% of T1 tumors, P=.03). On univariate/multivariate analysis, Ki-67 did not predict for overall survival (74.4% vs 72.6%), cause-specific survival (82.9% vs 82.1%), local relapse-free survival (83.6% vs 88.5%), distant metastasis-free survival (76.1% vs 81.4%), recurrence-free survival (65.5% vs 74.6%), and locoregional recurrence-free survival (81.6% vs 84.7%): P>.05 for all. Conclusions: Ki-67 appears to be a surrogate marker for aggressive disease and

    Locoregional control is a crucial step in the achievement of breast cancer cure. In ductal carcinoma in situ, breast irradiation significantly reduces the rates of local recurrence whatever the histological subtypes, as demonstrated by the NSABP-B17 trial (25.8 % of local recurrences without radiotherapy vs. 11.4 % with radiotherapy). In infiltrating breast carcinomas, complementary breast irradiation has been shown to significantly improve the local control and slightly the overall survival in five randomized trials. Following mastectomy, locoregional irradiation clearly reduces the chest wall and nodal relapse rates, especially in case of lesions more than 5 cm or with nodal involvement and/or large lymphatic or vascular emboli. Two recent randomized trials confirmed the benefit of well-adapted locoregional irradiation in all subgroups, especially in patients with one to three axillary involves nodes. In the Danish trial (including pre-menopausal high-risk women), radiotherapy reduced locoregional relapses from 32 to 9 % (p<0.001) and increased the 10-year survival rate from 45 to 54% (p<0.001). In the Canadian trial, locoregional relapse rate decreased from 25 to 13 % and the 10-year survival rate increased from 56 to 65 %. The meta-analysis published in 1995 by the EBCTCG showed only a modest benefit due to locoregional irradiation in breast cancer. However, when small or old trials were excluded due to imperfect methodology or inadequate irradiation techniques, the benefit of modern radiotherapy became much more evident in a population of 7,840 patients. Locoregional irradiation appears to be able to reduce the risk of metastatic evolution occurring after local or nodal relapse and must be integrated in a multidisciplinary strategy. Treatment toxicity (especially toxicity due to irradiation of internal mammary nodes) is of special concern, as anthracycline-based chemotherapy is prescribed more often.

    In the early phases of relapsing-remitting multiple sclerosis (RR-MS), a clear correlation between brain lesion load and clinical disability is often lacking, originating the so-called clinico-radiological paradox. Different factors may contribute to such discrepancy. In particular, synaptic plasticity may reduce the clinical expression of brain damage producing enduring enhancement of synaptic strength largely dependent on neurotrophin-induced protein synthesis. Cytokines released by the immune cells during acute inflammation can alter synaptic transmission and plasticity possibly influencing the clinical course of MS. In addition, immune cells may promote brain repair during the post-acute phases, by secreting different growth factors involved in neuronal and oligodendroglial cell survival. Platelet-derived growth factor (PDGF) is a neurotrophic factor that could be particularly involved in clinical recovery. Indeed, PDGF promotes long-term potentiation of synaptic activity in vitro and in MS and could therefore represent a key factor improving the clinical compensation of new brain lesions. The aim of the present study is to explore whether cerebrospinal fluid (CSF) PDGF concentrations at the time of diagnosis may influence the clinical course of RR-MS. At the time of diagnosis, we measured in 100 consecutive early MS patients the CSF concentrations of PDGF, of the main pro- and anti-inflammatory cytokines, and of reliable markers of neuronal damage. Clinical and radiological parameters of disease activity were prospectively collected during follow-up. CSF PDGF levels were positively correlated with prolonged relapse-free survival. Radiological markers of disease activity, biochemical markers of neuronal damage, and clinical parameters of disease progression were instead not influenced by PDGF concentrations. Higher CSF PDGF levels were associated with an anti-inflammatory milieu within the central nervous system. Our results suggest that PDGF could promote a

    Purpose: To report the clinical course of adolescents with medulloblastoma, with specific emphasis on prognosis and pattern of relapse. Methods and Materials: We retrospectively studied the clinical course and outcomes of children aged 10-20 years with medulloblastoma, treated at centers throughout Canada between 1986 and 2003. To better assess time to relapse, a cohort of patients aged 3-20 years at diagnosis was generated. Results: A total of 72 adolescents were analyzed. Five-year overall survival and event-free survival rates were 78.3% ± 5.4% and 68.0% ± 6.2%, respectively. Late relapses occurred at a median of 3.0 years (range, 0.3-6.8 years). In univariate analysis, conventional risk stratification and the addition of chemotherapy to craniospinal radiation did not have prognostic significance. Female patients had improved overall survival (p = 0.007). Time to relapse increased with age in a linear fashion. After relapse, patients faired poorly regardless of treatment modality. Patients who did not receive chemotherapy initially had improved progression-free survival at relapse (p 0.05). Conclusions: Our study suggests that adolescents with medulloblastoma might have a unique prognosis and pattern of relapse, dissimilar to those in younger children. They might benefit from different risk stratifications and prolonged follow-up. These issues should be addressed in future prospective trials

    Full Text Available The heterotetrameric protein kinase CK2 has been associated with oncogenic transformation, and our previous studies have shown that it may affect estrogenic signaling. Here, we investigate the role of the protein kinase CK2 in regulating ERα (estrogen receptor α signaling in breast cancer. We determined the correlation of CK2α expression with relapse free breast cancer patient survival utilizing Kaplan Meier Plotter (kmplot.com/analysis/ to mine breast cancer microarrays repositories. Patients were stratified according to ERα status, histological grade, and hormonal therapy. Luciferase reporter assays and flow cytometry were implemented to determine the impact of CK2 inhibition on ERE-mediated gene expression and expression of ERα protein. CK2α expression is associated with shorter relapse free survival among ERα (+ patients with grade 1 or 2 tumors, as well as among those patients receiving hormonal therapy. Biochemical inhibition of CK2 activity results in increased ER-transactivation as well as increased expression among ERα (+ and ERα (− breast cancer cell lines. These findings suggest that CK2 may contribute to estrogen-independent cell proliferation and breast tumor progression, and may potentially serve as a biomarker and pharmacological target in breast cancer.

    Full Text Available Abstract Background There is no consensus regarding the management of ovarian cancer patients, who have shown complete clinical response (CCR to primary therapy and have rising cancer antigen CA-125 levels but have no symptoms of recurrent disease. The present study aims to determine whether follow-up CA-125 levels can be used to identify the need for imaging studies and secondary cytoreductive surgery (CRS. Methods We identified 410 ovarian cancer patients treated at The University of Texas MD Anderson Cancer Center between 1984 and 2011. These patients had shown CCR to primary therapy. Follow-up was conducted based on the surveillance protocol of the MD Anderson Cancer Center. We used the Cox proportional hazards model and log-rank test to assess the associations between the follow-up CA-125 levels and secondary CRS and survival duration. Results The CA-125 level of 1.68 × nadir was defined as the indicator of recurrent disease (p  1.68 × nadir at relapse (55.7 and 10.4 months; p = 0.04 and 0.01, respectively. The overall and progression free survival duration of patients with asymptomatic relapse and underwent a secondary CRS was longer than that of patients with symptomatic relapse (p = 0.02 and 0.04 respectively. Conclusions The increase of serum CA-125 levels is an early warning of clinical relapse in ovarian cancer. Using CA-125 levels in guiding the treatment of patients with asymptomatic recurrent ovarian cancer, who have shown CCR to primary therapy, can facilitate optimal secondary CRS and extend the survival duration of the patients.

    Purpose: Three Phase II studies of preoperative radiotherapy and concurrent 5FU chemotherapy were undertaken. The primary endpoints were acute toxicity and pathologic complete response rate (pCR). Secondary endpoints were local recurrence-free survival (LRFS), disease-free survival (DFS), and overall survival (OS). Methods and Materials: A total of 134 patients with adenocarcinoma of the rectum (clinical T3/T4 or N1/N2) were treated. The initial cohort received 40 Gy in 20 fractions, the second 46 Gy in 23 fractions, and the third 50 Gy in 25 fractions. 5FU (225 mg/m 2 /day) was given continuously throughout radiotherapy. A total of 121 patients underwent surgical resection. Results: Treatment was well tolerated. Grade 3/4 acute toxicity was observed in 13%, 4%, and 14% of patients in the 40 Gy, 46 Gy, and 50 Gy cohorts, respectively (p = 0.20). pCR was documented in 15%, 23%, and 33% of patients, respectively (p = 0.07). The 2-year actuarial LRFS was 72%, 90%, and 89% (p = 0.02); DFS was 62%, 84%, and 78% (p = 0.02); and OS was 72%, 94%, and 92%, respectively (p = 0.03). Conclusions: All treatment schedules were well tolerated. There was a trend toward increased pCR with higher doses. A statistically significant increase in LRFS, DFS, and OS was seen with radiation doses of 46 Gy and greater, but there was no difference between 46 Gy and 50 Gy

    Lenalidomide plus dexamethasone is a reference treatment for relapsed multiple myeloma. The combination of the proteasome inhibitor carfilzomib with lenalidomide and dexamethasone has shown efficacy in a phase 1 and 2 study in relapsed multiple myeloma. We randomly assigned 792 patients with relapsed multiple myeloma to carfilzomib with lenalidomide and dexamethasone (carfilzomib group) or lenalidomide and dexamethasone alone (control group). The primary end point was progression-free survival. Progression-free survival was significantly improved with carfilzomib (median, 26.3 months, vs. 17.6 months in the control group; hazard ratio for progression or death, 0.69; 95% confidence interval [CI], 0.57 to 0.83; P=0.0001). The median overall survival was not reached in either group at the interim analysis. The Kaplan-Meier 24-month overall survival rates were 73.3% and 65.0% in the carfilzomib and control groups, respectively (hazard ratio for death, 0.79; 95% CI, 0.63 to 0.99; P=0.04). The rates of overall response (partial response or better) were 87.1% and 66.7% in the carfilzomib and control groups, respectively (P<0.001; 31.8% and 9.3% of patients in the respective groups had a complete response or better; 14.1% and 4.3% had a stringent complete response). Adverse events of grade 3 or higher were reported in 83.7% and 80.7% of patients in the carfilzomib and control groups, respectively; 15.3% and 17.7% of patients discontinued treatment owing to adverse events. Patients in the carfilzomib group reported superior health-related quality of life. In patients with relapsed multiple myeloma, the addition of carfilzomib to lenalidomide and dexamethasone resulted in significantly improved progression-free survival at the interim analysis and had a favorable risk-benefit profile.

    A retrospective analysis of 739 patients with breast cancer is presented. Factors influencing overall survival, recurrence-free interval and survival after first recurrence are analysed and discussed. None of the factors was affected by age or menopausal status at the time of presentation. Overall survival and recurrence-free intervals varied significantly with tumour size, extent of nodal spread and tumour site. Medially situated tumours, large tumours and extensive nodal spread were associated with earlier first recurrence and poor prognosis. No difference in survival or recurrence-free interval was observed between different surgical operations. Although overall survival was longer in patients who received post-operative radiotherapy, no significant differences in survival or disease-free intervals were noted when patients were standardised for operation or tumour stage. Survival after local recurrence was longer than survival after distant metastases, although the time of onset of local and distant disease followed an identical pattern. These results suggest that the tumour characteristics of size, site and nodal spread are important determinants of survival and recurrence-free interval in primary breast cancer. Local recurrence should be regarded as a manifestation of systemic disease. (author)

    Purpose: Long-term biochemical relapse-free survival (BRFS) rates in patients with clinical Stages T1-T3 prostate cancer continue to be scrutinized after treatment with external beam radiation therapy and brachytherapy. Methods and Materials: We report 15-year BRFS rates on 223 patients with clinically localized prostate cancer that were consecutively treated with I 125 or Pd 103 brachytherapy after 45-Gy neoadjuvant EBRT. Multivariate regression analysis was used to create a pretreatment clinical prognostic risk model using a modified American Society for Therapeutic Radiology and Oncology consensus definition (two consecutive serum prostate-specific antigen rises) as the outcome. Gleason scoring was performed by the pathologists at a community hospital. Time to biochemical failure was calculated and compared by using Kaplan-Meier plots. Results: Fifteen-year BRFS for the entire treatment group was 74%. BRFS using the Memorial Sloan-Kettering risk cohort analysis (95% confidence interval): low risk, 88%, intermediate risk 80%, and high risk 53%. Grouping by the risk classification described by D'Amico, the BRFS was: low risk 85.8%, intermediate risk 80.3%, and high risk 67.8% (p = 0.002). Conclusions: I 125 or Pd 103 brachytherapy combined with supplemental EBRT results in excellent 15-year biochemical control. Different risk group classification schemes lead to different BRFS results in the high-risk group cohorts

    Breast cancer is the most common cancer and the leading cause of cancer death among the women worldwide. The risk of local and distant recurrence is the highest during the first two years following the initial treatment. Very late relapse (after 12 years) is uncommon in breast cancer survivors. Herein, we report the characteristics and outcomes of 6 such cases of breast cancer. The mean age of the patients was 40.1 years (range 30-57) and the mean disease free survival was 19.6 years. Late relapse is not so common in breast cancer but can occur in any stage. Therefore, we suggest life-time follow up for every patient with breast cancer.

    A close relationship exists between immune response and tumor behavior. This study aimed to explore the associations between radiation-induced apoptosis (RIA) in peripheral blood lymphocytes (PBL) and clinical pathological variables. Furthermore, it assessed the role of RIA as a prognostic factor for survival in cervical carcinoma patients. Between February 1998 and October 2003, 58 consecutive patients with nonmetastatic, localized stage I-II cervical carcinoma who had been treated with radiotherapy (RT) ± chemotherapy were included in this study. Follow-up ended in January 2013. PBL subpopulations were isolated and irradiated with 0, 1, 2 and 8 Gy then incubated for 24, 48 and 72 h. Apoptosis was measured by flow cytometry and the ss value, a parameter defining RIA of lymphocytes, was calculated. Mean follow-up duration was 111.92 ± 40.31 months. Patients with lower CD8 T lymphocyte ss values were at a higher risk of local relapse: Exp(B) = 5.137, confidence interval (CI) 95 % = 1.044-25.268, p = 0.044. Similar results were observed for regional relapse: Exp(B) = 8.008, CI 95 % = 1.702-37.679, p = 0.008 and disease relapse: Exp(B) = 6.766, CI 95 % = 1.889-24.238, p = 0.003. In multivariate analysis, only the CD8 T lymphocyte ss values were found to be of prognostic significance for local disease-free survival (LDFS, p = 0.049), regional disease-free survival (RDFS, p = 0.002), metastasis-free survival (MFS, p = 0.042), disease-free survival (DFS, p = 0.001) and cause-specific survival (CSS p = 0.028). For the first time, RIA in CD8 T lymphocytes was demonstrated to be a predictive factor for survival in cervical carcinoma patients. (orig.)

    Clear cell sarcoma of the kidney (CCSK) is an uncommon paediatric renal tumour. Relapses occur in about 15% of the patients. Since detailed clinical information on relapsed CCSK is scarce, the current study aims to describe outcome of patients with relapsed CCSK treated according to recent European protocols. We analysed prospectively collected data of all CCSK patients who developed a relapse after complete remission at the end of primary treatment, entered onto SIOP and AIEOP trials between 1992 and 2012. Thirty-seven of 237 CCSK patients (16%) treated according to SIOP and AIEOP protocols developed a relapse. Median time from initial diagnosis to relapse was 17 months (range, 5.5 months - 6.6 years). Thirt-five out of thirty-seven relapses (95%) were metastatic; the most common sites of relapse were the brain (n=13), lungs (n=7) and bone (n=5). Relapse treatment consisted of chemotherapy (n=30), surgery (n=19) and/or radiotherapy (n=18), followed by high-dose chemotherapy and autologous bone marrow transplantation (ABMT) in 14 patients. Twenty-two out of thirty-seven patients (59%) achieved a second complete remission (CR); 15 of whom (68%) developed a second relapse. Five-year event-free survival (EFS) after relapse was 18% (95% CI: 4%-32%), and 5-year overall survival (OS) was 26% (95% CI: 10%-42%). In this largest series of relapsed CCSK patients ever described, overall outcome is poor. Most relapses are metastatic and brain relapses are more common than previously recognised. Intensive treatment aiming for local control, followed by high dose chemotherapy and ABMT, seems to be of benefit to enhance survival. Novel development of targeted therapy is urgently required.

    Purpose: The impact of delayed adjuvant radiotherapy in patients treated by surgical resection for peripheral or torso soft tissue sarcoma has not been well characterized. We retrospectively examined this issue in an institutional patient cohort. Methods and Materials: One hundred two adult patients were treated at the University of Washington Medical Center between 1981 and 1998 with postoperative radiotherapy for cure of a newly diagnosed soft tissue sarcoma. Of this group, 58 patients had primary intermediate- or high-grade disease of the extremity or torso (50 extremity/8 torso). Tumor histology was predominantly malignant fibrohistiocytoma, synovial cell sarcoma, and leiomyosarcoma. The group was dichotomized according to time interval from definitive resection to the start of adjuvant radiation. Twenty-six patients had a short delay, defined as <4 months, and 32 patients had a long delay of ≥4 months. Both groups were balanced with regard to site, size, margin status, and tumor depth; however, the long-delay group had a larger proportion of high histologic grade lesions and was treated more frequently with chemotherapy (31/32 [97%] for long-delay patients vs. 14/26 [54%] for short-delay patients). Median follow-up was 49.5 months (range: 7-113 months). Median follow-up for patients still alive was 54 months (range: 9-113 months). Survival outcomes were estimated by the Kaplan-Meier method. Results: Overall local relapse-free survival at 5 years from the time of definitive resection was 74%. On univariate analysis, estimated 5-year local relapse-free survival was significantly improved in the short-delay group (88% vs. 62% for the long-delay group, p = 0.048 by log rank). Overall distant relapse-free survival, disease-free survival, and overall survival at 5 years were 77%, 68%, and 86%, respectively. These survival outcomes were statistically equivalent in both radiation delay groups. There was no evidence to suggest that delaying adjuvant systemic therapy

    Environmental pollutants cause a potential hazard for survival in free-living animal populations. We modelled local survival (including emigration) by using individual mark–recapture histories of males and females in a population of a small insectivorous passerine bird, the pied flycatcher (Ficedula hypoleuca) living around a point source of heavy metals (copper smelter). Local survival of F. hypoleuca females did not differ between polluted and unpolluted environments. Males, however, showed a one-third higher local-survival probability in the polluted area. Low fledgling production was generally associated with decreased local survival, but males in the polluted area showed relatively high local survival, irrespective of their fledgling number. A possible explanation of higher local survival of males in the polluted area could be a pollution-induced change in hormone (e.g. corticosterone or testosterone) levels of males. It could make them to invest more on their own survival or affect the hormonal control of breeding dispersal. The local survival of males decreased in the polluted area over the study period along with the simultaneous decrease in heavy metal emissions. This temporal trend is in agreement with the stress hormone hypothesis. PMID:17148387

    Expression of the antiapoptotic and antiproliferative protein B-cell lymphoma 2 (Bcl-2) has been repeatedly shown to be associated with better locoregional control and patients' survival in oropharyngeal squamous cell carcinoma (OSCC). A regulatory (-938C>A) single-nucleotide polymorphism (SNP) in the inhibitory P2 BCL2 gene promoter generates significantly different BCL2 promoter activities and has been associated with outcome in different malignancies. The aim of the present study was to analyze the possible influence of the (-938C>A) SNP on survival of patients suffering from OSCC. One hundred and thirty-three patients with primary OSCC were retrospectively investigated. Bcl-2 expression of tumor cells was demonstrated by means of immunohistochemistry. Both the Bcl-2 expression and the (-938C>A) genotypes were correlated with the patients' survival. The (-938C>A) SNP was significantly related to Bcl-2 expression (P = 0.008). Kaplan-Meier curves revealed a significant association of the -938 SNP with relapse-free (P = 0.0283) and overall survival (P = 0.0247). Multiple Cox regression identified the BCL2 (-938CC) genotype as an independent prognostic factor for relapse [hazard ratio (HR) 1.898, P = 0.021] as well as for death in OSCC patients (HR 1.897, P = 0.013). The (-938C>A) SNP represents a potential novel prognostic marker in patients with OSCC that could help to identify a group of patients at high risk for relapse and death.

    Up to 30% of patients with acute myeloid leukemia (AML) and abnormal cytogenetics have persistent cytogenetic abnormalities (pCytAbnl) at morphologic complete remission (mCR). We hypothesized that the prognostic significance of pCytAbnl in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) in mCR varies with cytogenetic risk group. We analyzed the data on 118 patients with AML and abnormal cytogenetics who underwent HSCT in mCR, and developed a risk stratification model based on pCytAbnl and cytogenetic risk group. The model distinguished three groups of patients (Pcytogenetics (n=25) had the shortest median time to relapse (TTR; 5 months), relapse-free survival (RFS; 3 months), and overall survival (OS; 7 months). The group with favorable/intermediate risk cytogenetics and without pCytAbnl (n=43) had the longest median TTR (not reached), RFS (57 months), and OS (57 months). The group with pCytAbnl and favorable/intermediate risk cytogenetics, or, without pCytAbnl but with unfavorable risk cytogenetics (n=50) experienced intermediate TTR (18 months), RFS (9 months), and OS (18 months). In conclusion, a cytogenetic risk model identifies patients with AML in mCR with distinct rates of relapse and survival following HSCT. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Purpose The long-term update of US GI Intergroup RTOG 98-11 anal cancer trial found that concurrent chemoradiation (CCRT) with fluorouracil (5-FU) plus mitomycin had a significant impact on disease-free survival (DFS) and overall survival (OS) compared with induction plus concurrent 5-FU plus cisplatin. The intent of the current analysis was to determine the impact of tumor node (TN) category of disease on survival (DFS and OS), colostomy failure (CF), and relapse (local-regional failure [LRF] and distant metastases [DM]) in this patient group. Methods and Materials DFS and OS were estimated univariately by using the Kaplan-Meier method, and 6 TN categories were compared by the log–rank test (T2N0, T3N0, T4N0, T2N1-3, T3N1-3, and T4N1-3). Time to relapse and colostomy were estimated by the cumulative incidence method, and TN categories were compared using Gray’s test. Results Of 682 patients, 620 were analyzable for outcomes by TN category. All endpoints showed statistically significant differences among the TN categories of disease (OS, P<.0001; DFS, P<.0001; LRF, P<.0001; DM, P=.0011; CF, P=.01). Patients with the poorest OS, DFS, and LRF outcomes were those with T3-4N-positive (+) disease. CF was lowest for T2N0 and T2N+ (11%, 11%, respectively) and worst for the T4N0, T3N+, and T4N+ categories (26%, 27%, 24%, respectively). Conclusions TN category of disease has a statistically significant impact on OS, DFS, LRF, DM, and CF in patients treated with CCRT and provides excellent prognostic information for outcomes in patients with anal carcinoma. Significant challenges remain for patients with T4N0 and T3-4N+ categories of disease with regard to survival, relapse, and CF and lesser challenges for T2-3N0/T2N+ categories. PMID:24035327

CF was lowest for T2N0 and T2N+ (11%, 11%, respectively) and worst for the T4N0, T3N+, and T4N+ categories (26%, 27%, 24%, respectively). Conclusions: TN category of disease has a statistically significant impact on OS, DFS, LRF, DM, and CF in patients treated with CCRT and provides excellent prognostic information for outcomes in patients with anal carcinoma. Significant challenges remain for patients with T4N0 and T3-4N+ categories of disease with regard to survival, relapse, and CF and lesser challenges for T2-3N0/T2N+ categories.

    Purpose: The long-term update of US GI Intergroup RTOG 98-11 anal cancer trial found that concurrent chemoradiation (CCRT) with fluorouracil (5-FU) plus mitomycin had a significant impact on disease-free survival (DFS) and overall survival (OS) compared with induction plus concurrent 5-FU plus cisplatin. The intent of the current analysis was to determine the impact of tumor node (TN) category of disease on survival (DFS and OS), colostomy failure (CF), and relapse (local-regional failure [LRF] and distant metastases [DM]) in this patient group. Methods and Materials: DFS and OS were estimated univariately by using the Kaplan-Meier method, and 6 TN categories were compared by the log–rank test (T2N0, T3N0, T4N0, T2N1-3, T3N1-3, and T4N1-3). Time to relapse and colostomy were estimated by the cumulative incidence method, and TN categories were compared using Gray's test. Results: Of 682 patients, 620 were analyzable for outcomes by TN category. All endpoints showed statistically significant differences among the TN categories of disease (OS, P<.0001; DFS, P<.0001; LRF, P<.0001; DM, P=.0011; CF, P=.01). Patients with the poorest OS, DFS, and LRF outcomes were those with T3-4N-positive (+) disease. CF was lowest for T2N0 and T2N+ (11%, 11%, respectively) and worst for the T4N0, T3N+, and T4N+ categories (26%, 27%, 24%, respectively). Conclusions: TN category of disease has a statistically significant impact on OS, DFS, LRF, DM, and CF in patients treated with CCRT and provides excellent prognostic information for outcomes in patients with anal carcinoma. Significant challenges remain for patients with T4N0 and T3-4N+ categories of disease with regard to survival, relapse, and CF and lesser challenges for T2-3N0/T2N+ categories

    Smoke-free prison policies are increasingly common, but few studies have investigated relapse to smoking after release from prison. This study investigated return to tobacco smoking and correlates of smoking at reduced levels after release among adults recently released from smoke-free prisons in Queensland, Australia. A cross-sectional survey of 114 people at parole offices within two months of release from prison was used. The survey measured health, social, and criminological factors related to tobacco smoking. We used logistic regression to identify factors associated with reduced post-release smoking levels compared to pre-incarceration levels. 94% of participants relapsed to smoking within two months of release; 72% relapsed on the day of release. 62% of participants smoked significantly less per day after compared with before incarceration. Living with a partner (Odds Ratio (OR) 2.77, 95%CI 1.02-7.52), expressing support for smoke-free prison policies (OR 2.44, 95%CI 1.12-5.32), intending to remain abstinent post-release (OR 4.29, 95%CI 1.88-9.82), and intending to quit in the future (OR 3.88, 95%CI 1.66-9.07) were associated with reduced smoking post-release. Use of illicit drugs post-release was negatively associated with reduced smoking post-release (OR 0.27, 95%CI 0.09-0.79). In multivariate analyses, pre-release intention to remain smoke-free was associated with reduced smoking post-release (AOR 2.69, 95%CI 1.01-7.14). Relapse to smoking after release from smoke-free prisons is common, but many who relapse smoke less than before incarceration, suggesting that smoke-free prison policies may reduce post-release tobacco smoking. There is a need for tailored, evidence-based tobacco cessation interventions for people recently released from prison. Copyright © 2018 Elsevier B.V. All rights reserved.

    Purpose Osteosarcoma (OS) is the most common primary bone tumor. Despite complete surgical removal and intensive chemotherapeutic treatment, 30%-35% of patients with OS have local or systemic recurrence. Some patients survive multiple recurrences, but overall survival after OS recurrence is poor. This analysis aims to describe and identify factors influencing post-relapse survival (PRS) after a second OS relapse. Methods This is a retrospective analysis of 60 patients with a second relapse of OS of the extremities in 2 Italian centers between 2003 and 2013. Results Treatment for first and subsequent relapses was planned according to institutional guidelines. After complete surgical remission (CSR) following the first recurrence, patients experienced a second OS relapse with a median disease-free interval (DFI) of 6 months. Lung disease was prevalent: 44 patients (76%) had pulmonary metastases. Survival after the second relapse was 22% at 5 years. Lung disease only correlated with better survival at 5 years (33.6%) compared with other sites of recurrence (5%; p = 0.008). Patients with a single pulmonary lesion had a better 5-year second PRS (42%; p = 0.02). Patients who achieved a second CSR had a 5-year second PRS of 33.4%. Chemotherapy (p<0.001) benefited patients without a third CSR. Conclusions This analysis confirms the importance of an aggressive, repeated surgical approach. Lung metastases only, the number of lesions, DFI and CSR influenced survival. It also confirms the importance of chemotherapy in patients in whom surgical treatment is not feasible.

    From January 1975 to December 1984, 41 patients were treated by combined radiotherapy and surgery at Institut Gustave Roussy for Stage IB (288) and II (proximal) (103) carcinoma of uterine cervix. Standard treatment consisted of pre-operative utero-vaginal brachytherapy (60 Gy) using a mould technique followed by colpho-hysterectomy and external iliac lymphadenectomy. Overall 5 year actuarial survival for whole population was 87% and disease-free survival 85%. Locoregional relapse occurred in 23 patients (5%). Of these, 12 where central pelvic failures, 8 regional failures and 3 combined central and regional failures. Of 36 systemic relapses (8%), 12 relapsed concurrently in pelvis. Five year actuarial pelvic disease-free, disease-free and overall survival was 87, 85 and 87%, resp., for the whole population. 340 patients developed one or more complications [Grade 1: 198/441 (44%), Grade 2: 121/441 (27%) and Grade 3 or 4: 21/441 (4.7%)]. Five year actuarial survival for the whole population was poorer for histologically node positive than for node negative (89 vs. 55%, p<0.0001). Pre-operative brachytherapy by surgery can provide good local control with acceptable morbidity in early cervical cancer. (author). 39 refs.; 4 figs.; 4 tabs

    Purpose: To determine the frequency and clinical significance of epidermal growth factor receptor (EGFR) mutations in patients with potentially curable stage III non–small-cell lung cancer (NSCLC) who are eligible for definitive chemoradiotherapy (CRT). Patients and Methods: Between January 2001 and December 2010, we analyzed the EGFR mutational status in consecutive NSCLC patients who were treated by CRT. The response rate, relapse-free survival, 2-year relapse-free rate, initial relapse sites, and overall survival of the patients were investigated. Results: A total of 528 patients received CRT at our hospital during the study period. Of these, 274 were diagnosed as having nonsquamous NSCLC. Sufficient specimens for mutational analyses could be obtained from 198 of these patients. The proportion of patients with EGFR activating mutations was 17%. In addition to the well-known characteristics of patients carrying EGFR mutations (female, adenocarcinoma, and never/light smoker), the proportion of cases with smaller primary lesions (T1/2) was found to be higher in patients with EGFR mutations than in those with wild-type EGFR. Patients with EGFR mutations showed similar response rate, relapse-free survival, and 2-year relapse-free rates as compared to patients with wild-type EGFR. Local relapses as the site of initial relapse occurred significantly less frequently in patients with EGFR mutation (4% vs 21%; P=.045). Patients with EGFR mutations showed longer local control (adjusted hazard ratio 0.49; P=.043). After disease progression, a majority of the patients with EGFR mutations received EGFR tyrosine kinase inhibitors (62%), and these patients showed longer postprogression survival than those with wild-type EGFR. Conclusions: Our study is the first to show radiosensitive biology of EGFR-mutated tumors in definitive CRT with curative intent. This finding could serve as a credible baseline estimate of EGFR-mutated population in stage III nonsquamous NSCLC

    The authors undertook a retrospective study of seminoma patients treated with radiation therapy between 1961 and 1985. The classical group consisted of 66 patients, of whom 47 were stage I and 19 were stage II. The anaplastic group consisted of 21 patients, of whom 11 were stage I, nine were stage II, and one was stage III. The median follow-up was 66 months. The five-year crude survival rate for the entire group was 92%, for classical 96%, and for anaplastic 78% (P<.005). Similarly, there was a significant difference (P<.005) in actuarial relapse-free survival at 5 years between classical and anaplastic seminoma. For classical stage I, the relapse-free actuarial 5-year survival rate was 96; for classical stage II, 84%. For anaplastic stage I the relapse-free actuarial 5-year survival rate was 82%, and for stage II 75%. Six patients in the classical group (9%) failed treatment. In the anaplastic group, five patients or 24 failed treatment. Therefore, the authors' data suggest a difference in survival and failure rate between classical and anaplastic seminoma. Extratesticular seminoma with anaplastic histology has an even worse prognosis

    From 1966 through 1978, 128 patients with biopsy-proven adenocarcinoma of the prostate underwent external irradiation to the entire pelvis followed by additional irradiation with a field that encompassed the entire prostate with generous margins. Local recurrence was diagnosed when palpable regrowth occurred and was confirmed by biopsy. Eighteen patients (14%) had local recurrence. Actuarial (life table) local recurrence rates, however, were 24% for both for Stage B and C patients. Actuarial five year survival was 100% for the 10 Stage A patients, 91% for the 25 Stage B, and 78% for the 93 Stage C patients. Actuarial five year disease-free survival was 59% for Stage B and 69% for Stage C patients. Local recurrence was affected by the total dose to the whole pelvis and the dose at the center of the prostate. Disease-free survival was influenced by differentiation. High dose external irradiation to the prostate and regional lymph nodes offers the greatest probability of long-term disease-free survival for patients with localized disease. Late bowel complications were seen in 14 patients (11%), two of whom required colostomies. Late urinary tract complications were observed in five patients (4%)

  17. Neuroligin 4X overexpression in human breast cancer is associated with poor relapse-free survival.

    Full Text Available The molecular mechanisms involved in breast cancer progression and metastasis still remain unclear to date. It is a heterogeneous disease featuring several different phenotypes with consistently different biological characteristics. Neuroligins are neural cell adhesion molecules that have been implicated in heterotopic cell adhesion. In humans, alterations in neuroligin genes are implicated in autism and other cognitive diseases. Until recently, neuroligins have been shown to be abundantly expressed in blood vessels and also play a role implicated in the growth of glioma cells. Here we report increased expression of neuroligin 4X (NLGN4X in breast cancer. We found NLGN4X was abundantly expressed in breast cancer tissues. NLGN4X expression data for all breast cancer cell lines in the Cancer Cell Line Encyclopedia (CCLE was analyzed. Correlation between NLGN4X levels and clinicopathologic parameters were analyzed within Oncomine datasets. Evaluation of these bioinfomatic datasets results revealed that NLGN4X expression was higher in triple negative breast cancer cells, particularly the basal subtype and tissues versus non-triple-negative sets. Its level was also observed to be higher in metastatic tissues. RT-PCR, flow cytometry and immunofluorescence study of MDA-MB-231 and MCF-7 breast cancer cells validated that NLGN4X was increased in MDA-MB-231. Knockdown of NLGN4X expression by siRNA decreased cell proliferation and migration significantly in MDA-MB-231 breast cancer cells. NLGN4X knockdown in MDA-MB-231 cells resulted in induction of apoptosis as determined by annexin staining, elevated caspase 3/7 and cleaved PARP by flow cytometry. High NLGN4X expression highly correlated with decrease in relapse free-survival in TNBC. NLGN4X might represent novel biomarkers and therapeutic targets for breast cancer. Inhibition of NLGN4X may be a new target for the prevention and treatment of breast cancer.

    Purpose: A retrospective review evaluated the results of autologous bone marrow transplantation (A-BMT) for patients with relapsed Hodgkin's disease (HD) who were potentially treatable by radical radiation therapy (RRT). Methods and Materials: Evaluated patient cases met the following criteria: initial treatment with chemotherapy (with or without involved field radiation therapy 20 Gy to spinal cord); HD at time of salvage therapy limited to lymph nodes, Waldeyer's ring, liver, spleen, direct extension sites, and/or one lung. Results: There were 23 A-BMT patients treated between 1986 and 1991 who fulfilled the criteria. Three (13%) patients died from treatment-related complications and eight (35%) developed nonfatal Grade 3-4 complications. The 3-year actuarial disease-free survival rate was 61%. The 3-year disease-free survival rate was 55% for the nine patients with at least one prior disease-free interval (DFI) > 12 months, 67% for nine patients with DFI 0.10). These results are comparable to retrospective studies of RRT results in selected relapsed HD patients. Conclusions: Long-term disease-free survival is frequently possible with either A-BMT or RRT appropriately selected relapsed HD patients. In considering treatment options, important prognostic factors include initial stage of disease, number of prior relapses, DFI, and extent of relapsed disease

    Between 1971 and 1976, 64 patients less than 18 years of age with non-Hodgkin's lymphoma were treated at Boston's Children's Hospital Medical Center-Joint Center for Radiation Therapy. A multimodality approach was used, consisting of radiation therapy (3500 to 4500 rad), surgery, and chemotherapy. Since 1973, all patients have received a regimen initially comprising Adriamycin, Prednisone, 6-Mercaptopurine, Vincristine, and L-Asparaginase. Methotrexate was substituted for Adriamycin following a cumulative total dose of 450 mg/m/sup 2/. The 5-year actuarial survival for all patients was 61%, while relapse-free survival was 54%. The actuarial and relapse-free survival for patients presenting with localized disease was 75% and 72%, respectively. Median follow-up was 40 months and all relapses occurred within 24 months of initial therapy. A multidisciplinary approach, such as the current regimen, offers a good prognosis for this disease.

    Population-based evidence suggests that lower socioeconomic status (SES) negatively impacts the overall survival (OS) of children with leukemia; however, the relationships between SES and treatment-related mortality, relapse, and timing of relapse remain unclear. We examined OS, event-free survival (EFS) and cumulative incidence (CI) and timing of relapse by community-level poverty for 575 children aged 1-18 years with newly diagnosed acute lymphoblastic leukemia (ALL) treated on consecutive phase III multicenter Dana-Farber Cancer Institute ALL Consortium Protocols between 2000 and 2010. Children were categorized into high- and low-poverty areas for the analysis using aggregate U.S. Census data linked to zip code. Children living in high-poverty areas experienced a 5-year OS of 85% as compared with 92% for those in low-poverty areas (P = 0.02); poverty remained marginally significant (P = 0.07) after adjustment for immunophenotype, age, and white blood cell count. There were no differences detected in EFS or CI relapse by poverty area. However, 92% of the relapses observed in children from high-poverty areas occurred <36 months from complete remission, compared to 48% of those in children from low-poverty areas (P = 0.008). U.S. children with ALL living in high-poverty areas have a higher risk of early relapse when compared with those living in low-poverty areas despite uniform treatment. This may in part explain decreased OS observed in these children. This finding highlights disparities in childhood cancer outcomes by SES despite uniform treatment. Further investigations of the mechanistic pathways underlying this finding are needed. © 2016 Wiley Periodicals, Inc.

    Purpose: To identify prognostic factors and patterns of relapse for patients with Ewing sarcoma who underwent chemotherapy and R0 resection without radiation therapy (RT). Methods and Materials: We reviewed the medical records of patients who underwent surgical resection at our institution between 2000 and 2013 for an initial diagnosis of Ewing sarcoma. The associations of demographic and clinical factors with local control (LC) and patient outcome were determined by Cox regression. Time to events was measured from the time of surgery. Survival curves were estimated by the Kaplan-Meier method and compared by the log-rank test. Results: A total of 66 patients (median age 19 years, range 4-55 years) met the study criteria. The median follow-up was 5.6 years for living patients. In 43 patients (65%) for whom imaging studies were available, the median tumor volume reduction was 73%, and at least partial response by Response Evaluation Criteria in Solid Tumors was achieved in 17 patients (40%). At 5 years, LC was 78%, progression-free survival (PFS) was 59%, and overall survival (OS) was 65%. Poor histologic response (necrosis ≤95%) was an independent predictor of LC (hazard ratio [HR] 6.8, P=.004), PFS (HR 5.2, P=.008), and OS (HR 5.0, P=.008). Metastasis on presentation was also an independent predictor of LC (HR 6.3, P=.011), PFS (HR 6.8, P=.002), and OS (HR 6.7, P=.002). Radiologic partial response was a predictor of PFS (HR 0.26, P=.012), and postchemotherapy tumor volume was associated with OS (HR 1.06, P=.015). All deaths were preceded by distant relapse. Of the 8 initial local-only relapses, 5 (63%) were soon followed by distant relapse. Predictors of poor postrecurrence survival were time to recurrence <1 year (HR 11.5, P=.002) and simultaneous local and distant relapse (HR 16.8, P=.001). Conclusions: Histologic and radiologic response to chemotherapy were independent predictors of outcome. Additional study is needed to determine the role of adjuvant

    Nodal pelvic/retroperitoneal recurrent prostate cancer (PCa) after primary therapy can be treated with salvage lymph node dissection (salvage-LND) in order to delay disease progression and offer cure for a subset of patients. Whether adjuvant radiotherapy (ART) in affected regions improves the outcome by elimination of residual tumour burden remains unclear. A total of 93 patients with exclusively nodal PCa relapse underwent choline-positron-emission tomography-computed-tomography-directed pelvic/retroperitoneal salvage-LND; 46 patients had surgery only and 47 patients received ART in regions with proven lymph node metastases. In case of subsequent prostate specific antigen (PSA) progression, different imaging modalities were performed to confirm next relapse within or outside the treated region (TR). Mean follow-up was 3.2 years. Lymphatic tumour burden was balanced between the two groups. Additional ART resulted in delayed relapse within TR (5-year relapse-free rate 70.7 %) versus surgery only (5-year relapse-free rate 26.3 %, p < 0.0001). In both treatment arms, time to next relapse outside the TR was almost equal (median 27 months versus 29.6 months, p = 0.359). With respect to the detection of the first new lesion, regardless if present within or outside the TR, 5 years after the treatment 34.3 % of patients in the group with additional ART were free of relapse, versus 15.4 % in the surgery only group (p = 0.0122). ART had no influence on the extent of PSA reduction at latest follow-up compared to treatment with surgery only. ART after salvage-LND provides stable local control in TR and results in overall significant improved next-relapse-free survival, compared to patients who received surgery only in case of nodal PCa-relapse.

    We performed a retrospective, prognostic analysis of a cohort of patients with epilepsy according to time of relapse after four seizure-free years. Planned withdrawal of antiepileptic drugs (AEDs) and at least 3 years of follow-up after AED discontinuation were performed. The following two groups were assessed: (1) an early relapse (ER) group of patients who experienced recurrence during AED withdrawal and (2) a late relapse (LR) group of patients who experienced recurrence after completion of the AED discontinuation process. After dichotomization, the relapse rate, prognostic factors, and their impacts for each group were compared with those of a group of patients who continued to be seizure-free after AED withdrawal (SF group) using multiple logistic regression analysis. The AED intake mode was also analyzed. Two hundred seventeen (64.6%) of the 336 total patients experienced relapse. One hundred thirty-nine patients (41.4%) and 78 patients (23.2%) were included in the LR and ER groups, respectively. Symptom duration >120 months showed the strongest negative prognostic impact as demonstrated by the 4.7-fold higher risk of recurrence in the ER group compared with the SF group. Additional factors with a negative prognostic impact included an age at epilepsy onset of ≤20 years and the presence of localization-related epilepsy. No reliable predictor between the SF and LR groups was revealed. After exclusion of the SF group, post hoc analysis according to age at epilepsy onset and symptom duration showed that the above-mentioned negative prognostic factors significantly affected the relapse patterns of the LR and ER groups. The results suggest that longer symptom duration, which could be associated with intrinsic reactivation of epilepsy, is the strongest negative prognostic factor for relapse. Relapse after AED withdrawal in prolonged follow-up of seizure-free patients is one aspect of the natural history of epilepsy. © 2016 The Authors. Epilepsia published by

    To determine minimal dose levels required for local inhibition of orthodontic relapse by recombinant OPG protein (OPG-Fc), while also determining effects of injected OPG-Fc on alveolar bone and long bone. The Department of Orthodontics and Pediatric Dentistry at the University of Michigan. Eighteen male Sprague Dawley rats. Maxillary molars were moved with nickel-titanium springs and then allowed to relapse in Sprague Dawley rats. Upon appliance removal, animals were injected with a single dose of 1.0 mg/kg OPG-Fc, 0.1 mg/kg OPG-Fc, or phosphate-buffered saline (vehicle) just distal to the molar teeth. Tooth movement measurements were made from stone casts, which were scanned and digitally measured. Alveolar tissues were examined by histology. Micro-computed tomography was used to quantify changes in alveolar and femur bone. Local injection of OPG-Fc inhibited molar but not incisor relapse, when compared to vehicle-injected animals. No significant differences in alveolar or femur bone were seen between the three treatment groups after 24 days of relapse. Our results demonstrate that a single local injection of OPG-Fc effectively inhibits orthodontic relapse, with minimal systemic bone metabolic effects. Our results also show that a single injection of OPG-Fc will influence tooth movement only in teeth close to the injection site. These findings indicate that OPG-Fc has potential as a safe and effective pharmacological means to locally control osteoclasts, for uses such as maintaining anchorage during orthodontic tooth movement and preventing orthodontic relapse in humans. © 2015 John Wiley & Sons A/S.

    Many reports concerning radiation therapy for brain metastasis have been published, and which of the various methods urged by these reports provide optional control is still controversial. According to developing diagnosis of metastasis in CNS, therapeutic problems should be referred. We reviewed 67 patients with small cell lung cancer and brain metastasis who underwent brain irradiation (Ave. 47 Gy/5W), and all 15 patients with brain relapse after the irradiation. Relapsing patterns in this clinical setting were divided into local regrowth in the same lesions and re-metastasis (reseeding) in other regions, by reviewing follow up CT and MRI studies. Total survival among 15 patients with brain relapse and 52 without relapse was longer in the former cases than the later: 1-, and 2-year survival (47/19%, 13/8%) and MST (10.8/5.7 months), from the initial brain irradiation. The concerned significant factors limited in younger age, low value of LDH and improvement of NF. Of the 15 patients with brain relapse, 4 developed local regrowth and 11 did re-metastasis. The period of remission since brain irradiation were 172±94.4 and 393±281 days, respectively. Lower number of brain metastasis and lower value of LDH were shown in re-metastasis patients. At the time of brain relapse, 11 patients had recurrence of carcinomatous meningitis. 4 patients were treated with whole brain re-irradiation. All patients died of cancer, including 12 of relapsing CNS diseases and 3 of primary lesion and hepatic metastasis. Leukoencephalopathy developed in 2 patients. Survival since the brain relapse was 2 to 238 days without significant difference in cases of local regrowth and re-metastasis. According to our data on relapsing pattern of brain metastasis after conventional fractionated brain irradiation with an objective dose of 50 Gy, 75% of brain relapse were re-metastasis, we appreciate this irradiation for initial brain metastasis if limited to the brain.

    IGF2 is a tumor suppressor gene at locus 11p15. Many hepatoblastomas have loss of heterozygosity (LOH) at this locus. Earlier studies have not demonstrated any association between LOH and prognosis. Aim of the study was to evaluate the prognostic significance of LOH at 11p15.5 in hepatoblastomas. DNA was isolated from normal liver and tumor tissue in 20 patients with hepatoblastoma. PCR was performed and cases were classified as LOH present, absent or non-informative. Patients' follow-up data was analyzed using Fischer's exact test and Kaplan-Meier survival analysis for relapse-free survival (RFS) in relation to LOH. Ethical clearance was obtained from the institutional ethics board. All cases were informative for at least one microsatellite marker used. 4 of the 20 cases (20%) had LOH at 11p15.5. One patient died in the immediate postoperative period. 5 of 19 patients relapsed (26%). Of 4 patients who had LOH, 3 (75%) relapsed, the time to relapse being 7, 7 and 9 months, respectively. Of the 15 cases without LOH, 2 (13.3%) relapsed. 4 patients had mixed epithelial and mesenchymal histology; 3 of them had LOH. The 2 groups with and without LOH were well matched. The RFS for patients with LOH (n=4) was 13% (mean survival time [MST]: 8.7 months; 95CI 6.7-10.7), while the RFS for cases without LOH (n=15) was 75% (MST: 100.7 months; 95CI 74.5-126.8). Mixed epithelial and mesenchymal histology is more frequently associated with LOH on chromosome 11p15.5 than pure epithelial histology. LOH on chromosome 11p15.5 is associated with a significantly increased incidence of relapse and a significantly shorter relapse-free survival in patients with hepatoblastoma. The risk of relapse is higher and the RFS lower both in standard-risk and high-risk patients with hepatoblastoma if they demonstrate the presence of LOH at 11p15.5. © Georg Thieme Verlag KG Stuttgart · New York.

    Purpose Double-hit lymphomas (DHLs) and double-expressor lymphomas (DELs) are subtypes of diffuse large B-cell lymphoma (DLBCL) associated with poor outcomes after standard chemoimmunotherapy. Data are limited regarding outcomes of patients with relapsed or refractory (rel/ref) DEL or DHL who undergo autologous stem-cell transplantation (ASCT). We retrospectively studied the prognostic impact of DEL and DHL status on ASCT outcomes in patients with rel/ref DLBCL. Methods Patients with chemotherapy-sensitive rel/ref DLBCL who underwent ASCT at two institutions and in whom archival tumor material was available were enrolled. Immunohistochemistry for MYC, BCL2, and BCL6 and fluorescence in situ hybridization (FISH) for MYC were performed. In cases with MYC rearrangement or copy gain, FISH for BCL2 and BCL6 was also performed. Results A total of 117 patients were included; 44% had DEL and 10% had DHL. DEL and DHL were associated with inferior progression-free survival (PFS), and DHL was associated with poorer overall survival (OS). The 4-year PFS in patients with DEL compared with those with non-DEL was 48% versus 59% ( P = .049), and the 4-year OS was 56% versus 67% ( P = .10); 4-year PFS in patients with DHL compared with those with non-DHL was 28% versus 57% ( P = .013), and 4-year OS was 25% versus 61% ( P = .002). The few patients with concurrent DEL and DHL had a poor outcome (4-year PFS, 0%). In multivariable models, DEL and DHL were independently associated with inferior PFS, whereas DHL and partial response ( v complete response) at transplant were associated with inferior OS. Conclusion DEL and DHL are both associated with inferior outcomes after ASCT in patients with rel/ref DLBCL. Although ASCT remains a potentially curative approach, these patients, particularly those with DHL, are a high-risk subset who should be targeted for investigational strategies other than standard ASCT.

    Pomalidomide is a distinct oral IMiD® immunomodulatory agent with direct antimyeloma, stromal-support inhibitory, and immunomodulatory effects. The pivotal, multicenter, open-label, randomized phase 3 trial MM-003 compared pomalidomide + low-dose dexamethasone vs high-dose dexamethasone in 455 patients with refractory or relapsed and refractory multiple myeloma after failure of bortezomib and lenalidomide treatment. Initial results demonstrated significantly longer progression-free survival and overall survival with an acceptable tolerability profile for pomalidomide + low-dose dexamethasone vs high-dose dexamethasone. This secondary analysis describes patient outcomes by treatment history and depth of response. Pomalidomide + low-dose dexamethasone significantly prolonged progression-free survival and favored overall survival vs high-dose dexamethasone for all subgroups analyzed, regardless of prior treatments or refractory status. Both univariate and multivariate analyses showed that no variable relating to either the number (≤ or > 3) or type of prior treatment was a significant predictor of progression-free survival or overall survival. No cross-resistance with prior lenalidomide or thalidomide treatment was observed. Patients achieving a minimal response or better to pomalidomide + low-dose dexamethasone treatment experienced a survival benefit, which was even higher in those achieving at least a partial response (17.2 and 19.9 months, respectively, as compared with 7.5 months for patients with less than minimal response). These data suggest that pomalidomide + low-dose dexamethasone should be considered a standard of care in patients with refractory or relapsed and refractory multiple myeloma regardless of prior treatment.

    Measurement of residual disease following neoadjuvant chemotherapy that accurately predicts long-term survival in locally advanced breast cancer (LABC) is an essential requirement for clinical trials development. Several methods to assess tumor response have been described. However, the agreement between methods and correlation with survival in independent cohorts has not been reported. We report survival and tumor response according to the measurement of residual breast cancer burden (RCB), the Miller and Payne classification and the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, in 151 LABC patients. Kappa Cohen's coefficient (К) was used to test the agreement between methods. We assessed the correlation between the treatment outcome and overall survival (OS) and relapse-free survival (RFS) by calculating Harrell's C-statistic (c). The agreement between Miller and Payne classification and RCB classes was very high (К = 0.82). In contrast, we found a moderate-to-fair agreement between the Miller and Payne classification and RECIST criteria (К = 0.52) and RCB classes and RECIST criteria (К = 0.38). The adjusted C-statistic to predict OS for RCB index (0.77) and RCB classes (0.75) was superior to that of RECIST criteria (0.69) (P = 0.007 and P = 0.035, respectively). Also, RCB index (c = 0.71), RCB classes (c = 0.71) and Miller and Payne classification (c = 0.67) predicted better RFS than RECIST criteria (c = 0.61) (P = 0.005, P = 0.006 and P = 0.028, respectively). The pathological assessment of tumor response might provide stronger prognostic information in LABC patients.

    Purpose: To assess the clinical outcome and prostate-specific antigen (PSA) response and to determine prognostic factors for biochemical disease-free survival in patients treated with external beam radiotherapy following radical prostatectomy without hormonal therapy. Methods and Materials: Forty-eight patients were treated after prostatectomy with radiotherapy between March, 1988 and December, 1993. Seven patients had undetectable PSA ( 2.7. Five-year actuarial biochemical disease-free survival values were 71, 48, and 0%, respectively, for the three groups. Biochemical disease-free survival was not affected by preoperative PSA level, clinical stage, Gleason's score, pathologic stage, surgical margins, presence of undetectable PSA after surgery, surgery to radiation interval, total dose, or presence of clinically suspicious local disease. Based on digital rectal exam, there were no local failures. Conclusion: Biochemical disease-free survival after postprostatectomy radiation is predicted by the PSA at the time of irradiation. Clinical local control is excellent, but distant failure remains a significant problem in this population. The addition of concomitant systemic therapy should be investigated in patients with PSA >2.7

    To evaluate the survival benefit of intensity-modulated radiotherapy (IMRT) compared with conventional two-dimensional radiotherapy (2D-CRT) in nasopharyngeal carcinoma (NPC) using a large cohort with long follow-up. We retrospectively analysed 7081 non-metastatic NPC patients who received curative IMRT or 2D-CRT from February 2002 to December 2011. Of the 7081 patients, 2245 (31.7%) were administered IMRT, while 4836 (68.3%) were administered 2D-CRT. At 5 years, the patients administered IMRT had significantly higher local relapse-free survival (LRFS), loco-regional relapse-free survival (LRRFS), progression-free survival (PFS) and overall survival (OS) (95.6%, 92.5%, 82.1% and 87.4%, respectively) than those administered 2D-CRT (90.8%, 88.5%, 76.7% and 84.5%, respectively; p<0.001). The distant metastasis-free survival (DMFS) was higher for IMRT than 2D-CRT, with borderline significance (87.6% and 85.7%, respectively; p=0.056). However, no difference was observed between IMRT and 2D-CRT in nodal relapse-free survival (NRFS; 96.3% and 97.4%, respectively; p=0.217). Multivariate analyses showed that IMRT was an independent protective prognostic factor for LRFS, LRRFS and PFS, but not NRFS, DMFS or OS. IMRT provided an improved LRFS, LRRFS and PFS in both the early and advanced T classifications and overall stage for non-disseminated NPC compared with 2D-CRT. However, no significant advantage was observed in NRFS, DMFS or OS when IMRT was used. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To evaluate the response and survival rate after three-dimensional conformal radiation therapy (3D-CRT) of patients with a solitary sternal relapse of breast cancer. Seventeen patients between May 1996 and June 2005 were evaluated with the salvage 3D-CRT treatment of a solitary sternal relapse of breast cancer. The treatment fields included the gross tumor volume with 2 cm margins. The total radiation dose was 35.0 ∼61.5 Gy (biologic effective dose of 43.7 ∼76.9 Gy10 using an α/β ratio of 10 Gy), with a daily dose of 1.8∼3.0 Gy. The tumor response was evaluated by the change in maximum tumor size via follow up CT scans 1∼3 months after the completion of treatment. An objective tumor response was achieved in all patients, with a complete response in 5 patients and a partial response in 12 patients. The 5-year overall survival rate was 51.9% (median survival time: 27 months), and the most important factor affecting overall survival was the disease-free interval (interval from primary surgery of breast cancer to the development of sternal metastasis): The 5-year overall survival rate was 61.8% for patients with a disease-free interval ≥12 months and 0.0% for patients < with disease-free interval <12 months (p=0.03). The response to 3D-CRT was good in patients with solitary sternal relapse of breast cancer. Particularly, patients with long disease-free interval from primary surgery survived significantly longer than patients with short disease-free interval from primary surgery

    Purpose: To evaluate the local efficacy of concomitant chemoradiotherapy in patients with mostly refractory lymphoma. Methods and materials: Patients with refractory or chemoresistant-relapsed lymphoma and bulky life-threatening masses were included in this study. A split course of concomitant radiotherapy and chemotherapy (mostly cisplatin and etoposide) was delivered during a 6-week period. Weekly blood tests and a clinical examination using the Radiation Therapy Oncology Group guidelines were performed to assess acute toxicity. The tumor response was evaluated 1-3 months after treatment and at regular follow-up visits. Results: We enrolled 21 patients in the study between January 1998 and April 2003. Of the 21 patients, 60% had disseminated disease with bulky tumor masses and 85% had refractory lymphoma, of which most had been treated with at least two different chemotherapy regimens before concomitant chemoradiotherapy. Seventy-five percent received regimens containing cisplatinum and etoposide. The median radiation dose was 40 Gy (range, 12-62.5 Gy). Grade 3-4 hematologic toxicity and mucositis was observed in 70% and 30% of cases respectively, without any deaths. The overall response and complete remission rate was 70% and 20%, respectively. The 1-year overall survival and local progression-free survival rate was 20.4% and 54%, respectively. Three patients with localized disease were still alive 16, 33, and 48 months after treatment. Conclusion: Concomitant chemoradiotherapy for refractory or chemoresistant-relapsed lymphoma induced high hematologic toxicity, but seemed adequate for controlling local bulky tumor masses. No toxicity-related death was observed

    Effective treatments for hormone-receptor-positive (HR(+)) breast cancer (BC) following relapse/progression on nonsteroidal aromatase inhibitor (NSAI) therapy are needed. Initial Breast Cancer Trials of OraL EveROlimus-2 (BOLERO-2) trial data demonstrated that everolimus and exemestane significantly prolonged progression-free survival (PFS) versus placebo plus exemestane alone in this patient population. BOLERO-2 is a phase 3, double-blind, randomized, international trial comparing everolimus (10 mg/day) plus exemestane (25 mg/day) versus placebo plus exemestane in postmenopausal women with HR(+) advanced BC with recurrence/progression during or after NSAIs. The primary endpoint was PFS by local investigator review, and was confirmed by independent central radiology review. Overall survival, response rate, and clinical benefit rate were secondary endpoints. Final study results with median 18-month follow-up show that median PFS remained significantly longer with everolimus plus exemestane versus placebo plus exemestane [investigator review: 7.8 versus 3.2 months, respectively; hazard ratio = 0.45 (95% confidence interval 0.38-0.54); log-rank P NSAIs. These results further support the use of everolimus plus exemestane in this patient population. ClinicalTrials.gov #NCT00863655.

    Several studies have confirmed the advantages of delivering high doses of external beam radiotherapy to achieve optimal tumor-control outcomes in patients with localized prostate cancer. We evaluated the medium-term treatment outcome after high-dose, image-guided intensity-modulated radiotherapy (IMRT) using intra-prostate fiducial markers for clinically localized prostate cancer. In total, 141 patients with localized prostate cancer treated with image-guided IMRT (76 Gy in 13 patients and 80 Gy in 128 patients) between 2003 and 2008 were enrolled in this study. The patients were classified according to the National Comprehensive Cancer Network-defined risk groups. Thirty-six intermediate-risk patients and 105 high-risk patients were included. Androgen-deprivation therapy was performed in 124 patients (88%) for a median of 11 months (range: 2–88 months). Prostate-specific antigen (PSA) relapse was defined according to the Phoenix-definition (i.e., an absolute nadir plus 2 ng/ml dated at the call). The 5-year actuarial PSA relapse-free survival, the 5-year distant metastasis-free survival, the 5-year cause-specific survival (CSS), the 5-year overall survival (OS) outcomes and the acute and late toxicities were analyzed. The toxicity data were scored according to the Common Terminology Criteria for Adverse Events, version 4.0. The median follow-up was 60 months. The 5-year PSA relapse-free survival rates were 100% for the intermediate-risk patients and 82.2% for the high-risk patients; the 5-year actuarial distant metastasis-free survival rates were 100% and 95% for the intermediate- and high-risk patients, respectively; the 5-year CSS rates were 100% for both patient subsets; and the 5-year OS rates were 100% and 91.7% for the intermediate- and high-risk patients, respectively. The Gleason score (<8 vs. ≥8) was significant for the 5-year PSA relapse-free survival on multivariate analysis (p = 0.044). There was no grade 3 or 4 acute toxicity. The incidence of

    A simplified prognostic score is presented based on the multivariate analysis of 138 refractory/relapsed acute myeloid leukaemia (AML) patients (median age 55 years, range: 19-70) receiving a combination of intensive chemotherapy+Gemtuzumab as salvage regimen. Overall, 2-year event-free survival (EFS) and overall survival (OS) were 29±4% and 36±4%, respectively. Disease status (relapse Leukemia Prognostic Scoring System was then validated on an independent cohort of 111 refractory/relapsed AML patients. This new simplified prognostic score, using three clinical and biological parameters routinely applied, allow to discriminate around two third of the patients who should benefit from a salvage intensive regimen in the setting of refractory/relapsed AML patients. The other one third of the patients should receive investigational therapy.

Consecutive newly diagnosed GD patients who were scheduled to undergo ATD therapy from May 2011 to May 2014 were prospectively enrolled. Risk factors for GD relapse were analyzed by univariate and multivariate Cox proportional hazard analyses. The association between serum IL-17 expression at cessation and GD relapse was analyzed with relapse-free survival (RFS by the Kaplan–Meier survival analysis and log-rank test. Results. Of the 117 patients, 72 (61.5% maintained a remission for 12 months after ATD withdrawal and 45 (38.5% demonstrated GD relapse. The final multivariate Cox analysis indicated elevated IL-17 expression at cessation to be an independent risk factor for GD relapse within 12 months after ATD withdrawal (HR: 3.04, 95% CI: 1.14–7.67, p=0.021. Patients with higher expressions of IL-17 (≥median value at cessation demonstrated a significantly higher RFS than those with lower levels by the Kaplan–Meier analysis and log-rank test (p=0.028. Conclusions. This present study indicated elevated serum IL-17 expression at cessation to be a predictor for GD relapse within 12 months.

    Background and purpose: The aim of this retrospective study was to analyze the outcome of patients with locally advanced cervical carcinoma treated by adjuvant radiochemotherapy and to determine risk factors for local and distant relapse. Furthermore, acute and late effects of treatment were recorded. Patients and methods: A total of 72 patients with FIGO stages I-III cervical carcinoma were treated by radical hysterectomy, pelvic lymphadenectomy, and postoperative radiochemotherapy. Only patients with positive pelvic lymph nodes, parametrial involvement, positive margins, or tumor bulk were eligible. Patients were irradiated with a standard pelvic field (50.4 Gy in 28 fractions). The majority of patients received platinum-based chemotherapy. Results: After a median follow-up of 37 months, estimated 1-, 2-, and 4-year disease-free survival (DFS) and overall survival (OS) rates were 89%, 80%, 68% and 95%, 88%, 76%, respectively. Nine of the 72 patients had pelvic recurrences including only 1 isolated local failure; 23 of the 72 patients presented with distant relapse. The majority of relapses occurred within the first 3 years after adjuvant treatment. The number of positive pelvic lymph nodes (> 1) was the strongest prognostic factor for DFS. Treatment was well tolerated with transient acute hematologic ({proportional_to}30%) and gastrointestinal ({proportional_to}30%) grade 3 toxicity. Small bowel obstruction ({proportional_to}6%) was the only important late sequelae. Conclusion: Adjuvant radiochemotherapy in patients with advanced cervical cancer and several risk factors is highly effective to prevent local relapse. Future efforts to improve outcome should be placed on improvement of systemic control especially in subgroups with high-risk features for distant relapse. Combined treatment was well tolerated with moderate acute and late toxicity. (orig.)

    From 1966 to 1985, 103 patients with a localized follicular lymphoma were treated at the Fondation Bergonie. Clinical staging was performed using, after physical examination, chest X-rays, bipedal lymphangiography and unilateral bone marrow biopsy (BMB). The patients were then treated by radiotherapy with or without chemotherapy. Overall survival (OS) at 5 and 10 years is 69 and 56.3%, respectively. Relapse-free survival (RFS) is 53.7 and 49%. Unifactorial analysis shows three prognostic parameters to be independently significant in terms of OS: age, stage and B symptons. In terms of RFS, only 2 factors are significant: age and B symptons. Multivariate analysis (Cox model) shows that age is a more important prognostic factor than stage. 40 refs.; 3 figs.; 3 tabs

    We investigated the impact of low dose daily cisplatin on distant metastasis-free survival (DMFS) in locally advanced head and neck cancer treated with hyperfractionated radiotherapy (77 Gy in 70 fractions in 35 treatment days). In locally controlled tumors cisplatin led to better DMFS (p = 0.0272); Cisplatin may have acted independently of micrometastasis in locally advanced H and N cancer

    The study evaluates the effect of the locally recurring tumor on the incidence of metastatic disease in early stage carcinoma of the prostate. The probability of distant metastases was studied in 679 patients with Stage B-C/N0 carcinoma of the prostate treated at MSKCC between 1970 and 1985 (median follow-up of 97 months). Patients were staged with pelvic lymph node dissection and treated with retropubic 125I implantation. The actuarial distant metastases free survival (DMFS) for patients at risk at 15 years after initial therapy was 37%. Cox proportional hazard regression analysis of covariates affecting the metastatic outcome showed that local failure, used in the model as a time dependent variable, was the most significant covariate, although stage, grade, and implant volume were also found to be independent variables. The relative risk of metastatic spread subsequent to local failure was 4-fold increased compared to the risk without evidence of local relapse. The 15-year actuarial DMFS in 351 patients with local control was 77% compared to 24% in 328 patients who developed local relapses (p less than 0.00001). The relation of distant spread to the local outcome was observed regardless of stage, grade, or implant dose. Even stage B1/N0-Grade I patient with local control showed a 15-year actuarial DMFS of 82%, compared to 22% in patients with local relapse (p less than 0.00001). The median local relapse-free survival (LRFS) in the 268 patients with local recurrences who did not receive hormonal therapy before distant metastases were detected was 51 months, compared to a median of 71 months for DMFS in the same patients (p less than 0.001), consistent with the possibility that distant dissemination may develop secondary to local failure

    Purpose: Local recurrence is the dominant pattern of relapse in high-grade glioma (HGG) after conventional therapy. The recent use of antiangiogenic therapy has shown impressive radiologic and clinical responses in adult HGG. The preclinical data suggesting increased invasiveness after angiogenic blockade have necessitated a detailed analysis of the pattern of recurrence after therapy. Methods and Materials: A total of 162 consecutive patients with HGG, either newly diagnosed (n = 58) or with recurrent disease (n = 104) underwent therapy with bevacizumab at 10 mg/kg every 2 weeks and conventional chemotherapy with or without involved field radiotherapy until disease progression. The pattern of recurrence and interval to progression were the primary aims of the present study. Diffuse invasive recurrence (DIR) was defined as the involvement of multiple lobes with or without crossing the midline. Results: At a median follow-up of 7 months (range, 1–37), 105 patients had recurrence, and 79 patients ultimately developed DIR. The interval to progression was similar in the DIR and local recurrence groups (6.5 and 6.3 months, p = .296). The hazard risk of DIR increased exponentially with time and was similar in those with newly diagnosed and recurrent HGG (R 2 = 0.957). The duration of bevacizumab therapy increased the interval to recurrence (p < .0001) and improved overall survival (p < .0001). However, the pattern of relapse did not affect overall survival (p = .253). Conclusion: Along with an increase in median progression-free survival, bevacizumab therapy increased the risk of DIR in HGG patients. The risk of increased invasion with prolonged angiogenic blockade should be addressed in future clinical trials.

    Objective: To determine the maximal tolerated dose and the dose-limiting toxicity of hydroxycamptothecine (HCPT) concurrently combined with three-dimensional conformal radiotherapy (3DCRT) for unresectable or locally relapsed rectal cancer. Methods: Twenty-two patients with rectal cancer were enrolled into phase I study between 2004 -2007. HCPT was intravenously administered concurrently with 3DCRT weekly, dose given from 6, 8, 10 mg/m 2 or twice a week, dose given from 4, 6, 8, 10 mg/m 2 , respectively. Total radiation dose of 50 Gy was delivered to the whole pelvis at a fraction of 2 Gy per day for 5 weeks, with 10 - 16 Gy subsequent boost to tumor area. Dose-limiting toxicities (DLT) were defined as grade 3 or higher non-hematologic toxicity or grade 4 hematologic toxicity. Results: In the twice a week group, DLTs of grade 3 diarrhea were observed in 2 patient treated at dose of 6 mg/m 2 . In the weekly group, DLTs of grade 3 diarrhea and radiation-induced dermatitis were observed in I patient at dose of 8 mg/m 2 , and were not observed in the next 3 patients at the same dose level. However, at dose of 10 mg/m 2 , 2 patients had grade 3 diarrhea or nausea. The 5-year overall survival rate was 23% and the median survival time was 18 months. Conclusions: HCPT given concurrently with 3DCRT is safe and tolerable for patients with unresectable or locally relapsed rectal cancer. Either 8 mg/m 2 weekly or 4 mg/m 2 twice a week can be recommended for further study. The dose-limiting toxicities are grade 3 diarrhea, nausea and radiation-induced dermatitis. (authors)

    Relapse of leukemia in the postchemotherapy phase contributes to the poor prognosis and survival in patients with acute myeloid leukemia (AML). In an international phase IV trial (ClinicalTrials.gov; NCT01347996), 84 patients with AML in first complete remission who had not undergone transplantation received immunotherapy with histamine dihydrochloride (HDC) and low-dose IL-2 with the aim of preventing relapse. The dynamics of myeloid cell counts and expression of activation markers was assessed before and after cycles of immunotherapy and correlated with clinical outcome in terms of relapse risk and survival. During cycles, a pronounced increase in blood eosinophil counts was observed along with a reduction in monocyte and neutrophil counts. A strong reduction of blood monocyte counts during the first HDC/IL-2 treatment cycle predicted leukemia-free survival. The HDC component of the immunotherapy exerts agonist activity at histamine type 2 receptors (H2Rs) that are expressed by myeloid cells. It was observed that the density of H 2 R expression in blood monocytes increased during cycles of immunotherapy and that high monocyte H 2 R expression implied reduced relapse risk and improved overall survival. Several other activation markers, including HLA-DR, CD86, and CD40, were induced in monocytes and dendritic cells during immunotherapy but did not predict clinical outcome. In addition, expression of HLA-ABC increased in all myeloid populations during therapy. A low expression of HLA-ABC was associated with reduced relapse risk. These results suggest that aspects of myeloid cell biology may impact clinical benefit of relapse-preventive immunotherapy in AML. © Society for Leukocyte Biology.

    To assess the use of MRI-determined tumour regression grading (TRG) in local response assessment and detection of salvageable early local relapse after chemoradiotherapy (CRT) in patients with anal squamous cell carcinoma (ASCC). From a prospective database of patients with ASCC managed through a centralised multidisciplinary team, 74 patients who completed routine post-CRT 3- and 6-month MRIs (2009-2012) were reviewed. Two radiologists blinded to the outcomes consensus read and retrospectively assigned TRG scores [1 (complete response) to 5 (no response)] and related these to early local relapse (within 12 months) and disease-free survival (DFS). Seven patients had early local relapse. TRG 1/2 scores at 3 and 6 months had a 100 % negative predictive value; TRG 4/5 scores at 6 months had a 100 % positive predictive value. All seven patients underwent salvage R0 resections. We identified a novel 'tram-track' sign on MRI in over half of patients, with an NPV for early local relapse of 83 % at 6 months. No imaging characteristic or TRG score independently prognosticated for late relapse or 3-year DFS. Post-CRT 3- and 6-month MRI-determined TRG scores predicted salvageable R0 early local relapses in patients with ASCC, challenging current clinical guidelines. (orig.)

    One hundred and fifty-three patients with inoperable non-small cell lung cancer (NSCLC) treated with radiotherapy alone have been retrospectively analysed. Normalized Total Dose (NTD) as defined by Macejewski, TN-stage (AJC-system) and histology have been examined with respect to 5-year disease-free survival (DFS) and the patterns of failure so as to identify subgroups of patients that routinely should be treated with radical intent. The 5-year DFS for T1, 2-N0, 1 and T3-N0, 1 staged patients was 30% (7/23) and 25% (4/16) respectively when the tumor NTD (a/b=10 Gy) was 56-64 Gy vs. 12% (5/41) and 0% (0/10) when the NTD was 48-55 Gy. This difference was statistically significant for the squamous cell histology group. The higher doses significantly altered the patterns of death in N0, 1 staged squamous cell carcinoma and adenocarcinoma patients. Forty-five percent (22/55) and 41% (12/29) of squamous cell adenocarcinoma patients respectively, died from local relapse without evidence of distant metastases when NTD less than 55 Gy were given vs. 21% (9/42) and 13% (2/15) when the NTD delivered was 56-64 Gy (p<0.05). Although for N2, 3 staged patients or patients with direct extension of the tumor into the mediastinum death from local relapse occurred in 38% (10/26) of the high NTD treated patients vs. 51% (19/37) of the low-dose treated ones, the difference was not statistically significant. It is concluded that NSCLC patients should not a priori be considered as non-radiocurable. At least 30% of the patients with early local stages can be long-term disease-free survivors with readiation NTD up to 60 Gy and better results are to be expected with higher doses. Advanced T-stage without mediastinal involvement should be treated with radical intent since a high NTD could give cure rates of over 25%. The disappointing results for patients with mediastinal disease could perhaps be attributed to the low NTD delivered. For patients with good performance status

    There is limited information regarding the immunological predictors of post-allogeneic stem cell transplant (alloSCT) outcome in chronic lymphocytic leukaemia (CLL), such as mixed T-cell chimerism. We analysed 143 consecutive patients with relapsed/refractory CLL, transplanted between 2000 and 2012, to determine the prognostic relevance of mixed chimerism post-alloSCT and the ability of post-transplant immunomodulation to treat relapse. Mixed T-cell chimerism occurred in 50% of patients at 3 months and 43% at 6 months post-alloSCT; upon 3- and 6-month landmark analysis, this was associated with inferior progression-free survival (PFS) [Hazard ratio (HR) 1·93, P = 0·003 and HR 2·58, P CLL. © 2017 John Wiley & Sons Ltd.

    Full Text Available Ewing's sarcoma's relapse rarely occurs more than two years after the initial diagnosis. We report the case of a 26-year-old man with a history of Ewing's sarcoma of the left maxillary sinus at the age of 10 who presented with a very late local relapse, 16 years after the first occurrence of disease. Ultimate control was achieved after multimodal therapy including surgery, high-dose chemotherapy, and radiotherapy. This report indicates that local relapses of Ewing's sarcoma can be treated with curative intent in selected cases.

    About one half of adults with acute lymphoblastic leukemia are not cured of the disease and ultimately die. The objective of this study was to explore the factors influencing the outcome of adult patients with relapsed acute lymphoblastic leukemia. We analyzed the characteristics, the outcome and the prognostic factors for survival after first relapse in a series of 263 adult patients with acute lymphoblastic leukemia (excluding those with mature B-cell acute lymphoblastic leukemia) prospectively enrolled in four consecutive risk-adapted PETHEMA trials. The median overall survival after relapse was 4.5 months (95% CI, 4-5 months) with a 5-year overall survival of 10% (95% CI, 8%-12%); 45% of patients receiving intensive second-line treatment achieved a second complete remission and 22% (95% CI, 14%-30%) of them remained disease free at 5 years. Factors predicting a good outcome after rescue therapy were age less than 30 years (2-year overall survival of 21% versus 10% for those over 30 years old; P<0.022) and a first remission lasting more than 2 years (2-year overall survival of 36% versus 17% among those with a shorter first remission; P<0.001). Patients under 30 years old whose first complete remission lasted longer than 2 years had a 5-year overall survival of 38% (95% CI, 23%-53%) and a 5-year disease-free survival of 53% (95% CI, 34%-72%). The prognosis of adult patients with acute lymphoblastic leukemia who relapse is poor. Those aged less than 30 years with a first complete remission lasting longer than 2 years have reasonable possibilities of becoming long-term survivors while patients over this age or those who relapse early cannot be successfully rescued using the therapies currently available.

    had a significantly lower S phase fraction (NP 13.1 vs. TR 22.0, p < 0.05). The overall survival following breast relapse was 64% at 10 years and 49% at 15 years. With a mean follow-up of 10.4 years following breast relapse, patients with NP had better 10-year overall survival (TR 55% vs. NP 75%, p < 0.0001), distant disease-free survival (TR 41% vs. NP 85%, p < 0.0001), and cause-specific survival (TR 55% vs. NP 90%, p < 0.0001). Conclusion: It appears that a significant portion of patients who experience ipsilateral breast tumor relapse following conservative surgery and radiation therapy have new primary tumors as opposed to true local recurrences. True recurrence and new primary tumor ipsilateral breast tumor relapses have different natural histories, different prognoses, and, in turn, different implications for therapeutic management.

    Mantle-cell lymphoma is an aggressive B-cell lymphoma with a poor prognosis. Both ibrutinib and temsirolimus have shown single-agent activity in patients with relapsed or refractory mantle-cell lymphoma. We undertook a phase 3 study to assess the efficacy and safety of ibrutinib versus temsirolimus in relapsed or refractory mantle-cell lymphoma. This randomised, open-label, multicentre, phase 3 clinical trial enrolled patients with relapsed or refractory mantle-cell lymphoma confirmed by central pathology in 21 countries who had received one or more rituximab-containing treatments. Patients were stratified by previous therapy and simplified mantle-cell lymphoma international prognostic index score, and were randomly assigned with a computer-generated randomisation schedule to receive daily oral ibrutinib 560 mg or intravenous temsirolimus (175 mg on days 1, 8, and 15 of cycle 1; 75 mg on days 1, 8, and 15 of subsequent 21-day cycles). Randomisation was balanced by using randomly permuted blocks. The primary efficacy endpoint was progression-free survival assessed by a masked independent review committee with the primary hypothesis that ibrutinib compared with temsirolimus significantly improves progression-free survival. The analysis followed the intention-to-treat principle. The trial is ongoing and is registered with ClinicalTrials.gov (number NCT01646021) and with the EU Clinical Trials Register, EudraCT (number 2012-000601-74). Between Dec 10, 2012, and Nov 26, 2013, 280 patients were randomised to ibrutinib (n=139) or temsirolimus (n=141). Primary efficacy analysis showed significant improvement in progression-free survival (pibrutinib versus temsirolimus (hazard ratio 0·43 [95% CI 0·32-0·58]; median progression-free survival 14·6 months [95% CI 10·4-not estimable] vs 6·2 months [4·2-7·9], respectively). Ibrutinib was better tolerated than temsirolimus, with grade 3 or higher treatment-emergent adverse events reported for 94 (68%) versus 121 (87

    The objective of this study was to evaluate the prognostic value of anemia in uterine cervical carcinoma patients treated with irradiation. A total of 162 patients diagnosed with stage IIA-IIIB cervical carcinoma by the criteria of International Federation of Gynecology and Obstetrics and treated with irradiation were analyzed. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. Patients were divided into two groups according to the hemoglobin level before treatment: 10 mm) assessed by computed tomography had impact on overall survival (p=0.008), disease-free survival (p=0.023) and relapse-free survival (p=0.028). Using multivariate analysis, the hemoglobin level before treatment was found to be an independent prognostic factor for overall survival (p=0.001), disease-free survival (p=0.040) and local relapse-free survival (p=0.013); Iymph node status assessed by computed tomography had impact on overall survival (p=0.030) and local relapse-free survival (p=0.038). Hemoglobin level before treatment is a significant prognostic factor for patients with uterine cervical carcinoma treated with irradiation. (author)

    Purpose: Basal-like carcinoma of the breast is associated with genetic instability and aggressive behavior. In this study, we evaluated the luminal cytokeratin marker CK-19 in young women with breast cancer treated with conservative surgery and radiation therapy (CS+RT). Methods: Primary tumor specimens from a cohort of 158 young premenopausal women (range, 25-49 years) treated with CS+RT with a median follow-up of 6.25 years were constructed into a tissue microarray. The array was stained for ER, PR, HER2, CK19, and p53. The molecular profiles were correlated with clinical-pathologic factors, overall, local, and distant relapse-free survival. The association between CK19, other co-variables, and outcome was assessed in a multivariate model. Results: Positive expression of ER, PR, HER-2/neu, CK19, and p53 were 33.1%, 34.5%, 10.0%, 79.5%, and 20.9%, respectively. With 20 local relapses and 38 distant metastases, the 10-year overall, breast relapse-free, and distant relapse-free survival were 79.65%, 87.29%, and 67.35%, respectively. Tumor stage and nodal status were associated with distant relapse-free and overall survival. In multivariate analysis, CK19 negativity was a predictor poor local (RR, 3.54; 95% CI, 1.87-7.65; p < 0.01) distant (RR, 1.44; 95% CI, 0.86-2.70; p = 0.17), and overall survival (RR, 1.89; 95% CI, 1.04-3.55; p = 0.03). Conclusions: Lack of CK19 expression identifies a subset of patients with a significantly higher risk of local relapse. Distant relapse and overall survival rates also correlated with CK19 negativity. Further evaluation of the prognostic significance of basal and luminal cytokeratins in young women with breast cancer is warranted

    Cytogenetic evolution (CGE) in patients with myeloid neoplasms who relapsed after an allogeneic (allo) hematopoietic cell transplantation (HCT) has been evaluated by only few studies. The effect of the CGE on survival of relapsed allo-HCT recipients is not clear. The effect of previously received chemotherapy to induce CGE in this patient population has not been studied. The aims of our study are to (1) characterize the patterns of cytogenetic change in patients with myeloid neoplasms who relapsed after an allo-HCT, (2) evaluate the effect of CGE on survival, and (3) explore the association of CGE with previous chemotherapy (including the lines of salvage therapy, type of induction, and conditioning therapy). Of 49 patients with a myeloid malignancy (27 acute myeloid leukemia [AML], 19 myelodysplastic syndrome [MDS]/myeloproliferative neoplasm [MPN], and 3 chronic myelogenous leukemia) who relapsed after an allo-HCT, CGE was observed in 25 (51%), whereas 24 patients had unchanged cytogenetic findings at relapse. The CGE group carried more cytogenetic abnormalities at original diagnosis. The most frequent cytogenetic change was the acquisition of 3 or more new chromosomal abnormalities followed by acquisition of unbalanced abnormalities, aneuploidy, and emergence of apparently new clones unrelated to the original clone. The CGE cohort had higher proportion of MDS and MPN and fewer patients with de novo AML. Disease risk assessment category showed a trend to higher frequency of high-risk patients in the CGE group, though the difference was not statistically significant. Time from diagnosis to transplantation and time from transplantation to relapse were not different between the CGE and non-CGE groups. CGE and non-CGE cohorts had similar exposures to salvage therapy and to induction chemotherapy, as well as similar conditioning regimens; thus, no particular type of chemotherapy emerged as a predisposing factor to CGE. CGE was associated with significantly shortened

    Ten patients with newly diagnosed, advanced prostatic cancer were treated with radiotherapy and hormone therapy to improve tumor control and survival. Eight patients with hormonally relapsed prostatic cancer were treated with radiotherapy to improve their quality of life. Local control of the tumor was achieved in 9 of 10 patients with newly diagnosed, advanced prostatic cancer. Five of eight patients with hormonally relapsed prostatic cancer obtained improved quality of life. Combined radiotherapy and hormone therapy were effective in the treatment of newly diagnosed, advanced prostatic cancer, and radiotherapy was useful for improving the quality of life of patients with hormonally relapsed prostatic cancer.

    Relapse remains the major cause of treatment failure in children with high-risk acute lymphoblastic leukaemia (ALL) undergoing allogeneic haematopoietic stem-cell transplantation (allo-SCT). Prognosis is considered dismal but data on risk factors and outcome are lacking from prospective studies. We...... analysed 242 children with recurrence of ALL after first allo-SCT enrolled in the Berlin-Frankfurt-Munster (BFM) ALL-SCT-BFM 2003 and ALL-SCT-BFM international 2007 studies. Median time from allo-SCT to relapse was 7·7 months; median follow-up from relapse after allo-SCT until last follow-up was 3·4 years....... The 3-year event-free survival (EFS) was 15% and overall survival (OS) was 20%. The main cause of death was disease progression or relapse (86·5%). The majority of children (48%) received salvage therapy without second allo-SCT, 26% of the children underwent a second allo-SCT and 25% received palliative...

    Fifty-five patients with multiple myeloma were treated with both upper and lower hemibody irradiation between January 1985 and January 1991; 42 had relapsed post-plateau and 13 were chemo-resistant to initial therapy. Fifteen patients received [alpha]IFN-2b maintenance therapy post-DHBI, at a dose of 3 Mu three times per week. Ninety-five per cent of patients experienced symptomatic improvement in bone pain post-DHBI, 21% of whom discontinued opiate analgesics altogether; 63% had a minor biochemical response and 38% had a partial biochemical response. The overall survival (OS) and progression free survivals (PFS) in all patients were 11 months and 8 months respectively. No significant difference was noted in either OS or PFS, according to whether patients were chemoresistant or had relapsed post-plateau. [alpha]IFN did not appear to prolong survival (OS or PFS) post-DHBI. We conclude that DHBI is an effective treatment in patients with relapsed multiple myeloma and in those who are chemoresistant to initial therapy. Cytopenia was a significant problem post-DHBI, such that the role of maintenance [alpha]IFN therapy could not be fully evaluated. (author).

    Purpose: Local recurrence remains one of the major causes of failure in nasopharyngeal carcinoma (NPC). Stereotactic radiosurgery and fractionated stereotactic radiation therapy (FSRT) have recently evolved as a salvage option of NPC. This study was conducted to review the treatment outcome after FSRT for NPC. Methods and Materials: Between September 1999 and December 2005, 90 patients with persistent (Group 1: n = 34, relapse within 6 months of RT) or recurrent (Group 2: n = 56, relapse beyond 6 months) NPC received FSRT using multiple noncoplanar arcs of 8-MV photon to the target. Median FSRT dose was 18 Gy in three fractions (Group 1) or 48 Gy in six fractions (Group 2). Median follow-up was 20.3 months. Results: Complete response rate after FSRT was 66% for Group 1 and 63% for Group 2. One-, 2-, and 3-year disease-specific survival (DSS) and progression-free survival (PFS) rates for all patients were 82.6%, 74.8%, 57.5%, and 72.9%, 60.4%, 54.5%, respectively. Three-year local failure-free survival, DSS, and PFS rates were 89.4%, 80.7%, and 72.3% for Group 1, and 75.1%, 45.9%, and 42.9% for Group 2, respectively. Multivariate analysis showed that recurrent disease and large tumor volume were independent factors that predicted poorer DSS and PFS. Seventeen patients developed late complications, including 2 with fatal hemorrhage. Conclusions: Our results indicate that FSRT is effective for patients with persistent and recurrent NPC. Compared with reported results of radiosurgery, FSRT provides satisfactory tumor control and survival with a lower risk of complications and it may be a better treatment for local failures of NPC

    Although sometimes presenting as an indolent lymphoma, mantle cell lymphoma (MCL) is an aggressive disease, hardly curable with standard chemo-immunotherapy. Current approaches have greatly improved patients' outcomes, nevertheless the disease is still characterized by high relapse rates. Before approval by EMA, Italian patients with relapsed/refractory MCL were granted ibrutinib early access through a Named Patient Program (NPP). An observational, retrospective, multicenter study was conducted. Seventy-seven heavily pretreated patients were enrolled. At the end of therapy there were 14 complete responses and 14 partial responses, leading to an overall response rate of 36.4%. At 40 months overall survival was 37.8% and progression free survival was 30%; disease free survival was 78.6% at 4 years: 11/14 patients are in continuous complete response with a median of 36 months of follow up. Hematological toxicities were manageable, and main extra-hematological toxicities were diarrhea (9.4%) and lung infections (9.0%). Overall, 4 (5.2%) atrial fibrillations and 3 (3.9%) hemorrhagic syndromes occurred. In conclusions, thrombocytopenia, diarrhea and lung infections are the relevant adverse events to be clinically focused on; regarding effectiveness, ibrutinib is confirmed to be a valid option for refractory/relapsed MCL also in a clinical setting mimicking the real world.

    Objective To study the prognostic value of leucocyte disorders in a prospective cohort of cervical cancer patients receiving definitive chemoradiation plus image—guided adaptive brachytherapy (IGABT). Results 113 patients were identified. All patients received a pelvic irradiation concomitant with chemotherapy, extended to the para-aortic area in 13 patients with IVB disease. Neutrophilia and leukocytosis were significant univariate prognostic factors for poorer local failure-free survival (p = 0.000 and p = 0.002, respectively), associated with tumor size, high-risk clinical target volume (HR-CTV) and anemia. No effect was shown for distant metastases but leukocytosis and neutrophila were both poor prognostic factors for in-field relapses (p = 0.003 and p 7,500/μl (p = 0.018) were independent factors for poorer survival without local failure, with hazard ratio (HR) of 3.1. Materials and methods We examined patients treated in our Institution between April 2009 and July 2015 by concurrent chemoradiation (45 Gy in 25 fractions +/− lymph node boosts) followed by a magnetic resonance imaging (MRI)-guided adaptive pulse-dose rate brachytherapy (15 Gy to the intermediate-risk clinical target volume). The prognostic value of pretreatment leucocyte disorders was examined. Leukocytosis and neutrophilia were defined as a leukocyte count or a neutrophils count exceeding 10,000 and 7,500/μl, respectively. Conclusions Neutrophilia is a significant prognostic factor for local relapse in locally advanced cervical cancer treated with MRI-based IGABT. This biomarker could help identifying patients with higher risk of local relapse and requiring dose escalation. PMID:27713124

    Background Manganese superoxide dismutase (MnSOD) plays a critical role in the detoxification of mitochondrial reactive oxygen species, constituting a major cellular defense mechanism against agents that induce oxidative stress. A genetic polymorphism in the mitochondrial targeting sequence of this gene has been associated with increased cancer risk and survival in breast cancer. This base pair transition (-9 T > C) leads to a valine to alanine amino acid change in the mitochondrial targeting sequence. A polymorphism has also been identified in the proximal region of the promoter (-102 C>T) that alters the recognition sequence of the AP-2 transcription factor, leading to a reduction in transcriptional activity. The aim of our study was to investigate possible associations of the -102 C>T polymorphism with overall and relapse-free breast cancer survival in a hospital-based case-only study. Materials and methods The relationship between the MnSOD -102 C>T polymorphism and survival was examined in a cohort of 291 women who received chemotherapy and/or radiotherapy for incident breast cancer. The MnSOD -102 C>T genotype was determined using a TaqMan allele discrimination assay. Patient survival was evaluated according to the MnSOD genotype using Kaplan–Meier survival functions. Hazard ratios were calculated from adjusted Cox proportional hazards modeling. All statistical tests were two-sided. Results In an evaluation of all women, there was a borderline significant reduction in recurrence-free survival with either one or both variant alleles (CT + TT) when compared with patients with wild-type alleles (CC) (odds ratio, 0.65; 95% confidence interval, 0.42–1.01). When the analysis was restricted to patients receiving radiation therapy, there was a significant reduction in relapse-free survival in women who were heterozygous for the MnSOD -102 genotype (relative risk, 0.40; 95% confidence interval, 0.18–0.86). Similarly, when the homozygous and heterozygous variant

    Purpose: The practice policy at the University of Washington has been to employ fast neutron radiotherapy for soft tissue sarcoma lesions with prognostic features predictive for poor local control. These include gross residual disease/inoperable disease, recurrent disease, and contaminated surgical margins. Cartilaginous sarcomas have also been included in this high-risk group. This report updates and expands our previously described experience with this approach. Methods and Materials: Eighty-nine soft tissue sarcoma lesions in 72 patients were treated with neutron radiotherapy in our department between 1984 and 1996. Six patients, each with solitary lesions, were excluded from analysis due to lack of follow-up. Seventy-three percent were treated with fast neutron radiation alone, the rest with a combination of neutrons and photons. Median neutron dose was 18.3 nGy (range 4.8-22). Forty-two patients with solitary lesions were treated with curative intent. Thirty-one patients (including 7 previously treated with neutrons) with 41 lesions were treated with the goal of local palliation. Tumors were predominantly located in the extremity and torso. Thirty of 35 (85%) of curative group patients treated postoperatively had close or positive surgical margins. Thirty-four (82%) lesions treated for palliation were unresectable. Thirty-five patients (53%) were treated at the time of recurrence. Median tumor size at initial presentation was 8.0 cm (range 0.6-29), median treated gross disease size was 5.0 cm (range 1-22), and 46/69 evaluable lesions (67%) were judged to be of intermediate to high histologic grade. Fourteen patients (21%) had chondrosarcomas. Results: Median follow-up was 6 months (range 2-47) and 38 months (range 2-175) for the palliative and curative groups, respectively. Kaplan-Meier estimates were obtained for probability of local relapse-free survival (68%), distant disease-free survival (59%), cause-specific survival (68%), and overall survival (66%) at

    Full Text Available The aim of this report is to unveil specific prognostic factors for retroperitoneal sarcoma (RPS patients by univariate and multivariate statistical techniques. A phase I-II study on localized RPS treated with high-dose ifosfamide and radiotherapy followed by surgery (ISG-STS 0303 protocol demonstrated that chemo/radiotherapy was safe and increased the 3-year relapse-free survival (RFS with respect to historical controls. Of 70 patients, twenty-six developed local, 10 distant, and 5 combined relapse. Median disease-free interval (DFI was 29.47 months. According to a discriminant function analysis, DFI, histology, relapse pattern, and the first treatment approach at relapse had a statistically significant prognostic impact. Based on scientific literature and clinical expertise, clinicopathological data were analyzed using both a supervised and an unsupervised classification method to predict the prognosis, with similar sample sizes (66 and 65, resp., in casewise approach and 70 in mean-substitution one. This is the first attempt to predict patients’ prognosis by means of multivariate statistics, and in this light, it looks noticable that (i some clinical data have a well-defined prognostic value, (ii the unsupervised model produced comparable results with respect to the supervised one, and (iii the appropriate combination of both models appears fruitful and easily extensible to different clinical contexts.

    codynamic interactions are also likely in view of its adverse effect profile. There is no consensus on the treatment of patients with refractory or relapsed mantle cell lymphoma, or for patients with relapsed or possibly refractory chronic lymphocytic leukaemia. Ibrutinib inhibits an enzyme involved in regulating B lymphocyte activity. It has been authorised in the European Union for these conditions. Clinical evaluation of ibrutinib in mantle cell lymphoma is based on a single non-comparative trial in 111 patients, in which the median overall survival time was 22.5 months. Clinical evaluation of ibrutinib in chronic lymphocytic leukaemia is based on two randomised trials. One unblinded trial compared ibrutinib versus ofatumumab and involved 391 patients, most of whom were sufficiently fit to receive anticancer combination therapy. Ibrutinib was more effective than ofatumumab, but the choice of this comparator might not have been appropriate for most of the patients who received it. The other double-blind, placebo-controlled trial involved 578 patients with relapsed or refractory chronic lymphocytic leukaemia. Ibrutinib was added to the bendamustine + rituximab combination. No significant difference in mortality was observed between the two groups. The main adverse effects of ibrutinib were: gastrointestinal disorders such as diarrhoea; life-threatening infections and bleeding disorders; and cardiac disorders, including atrial fibrillation. Ibrutinib carries a risk of multiple pharmacokinetic interactions. Pharmacodynamic interactions are also likely in view of its adverse effect profile.

    Malignant de novo lipogenesis is strongly linked to the aggressiveness of prostate cancer (PCa) under experimental conditions. {sup 11}C-Acetate PET/CT is a potential noninvasive biomarker of malignant lipogenesis in PCa, but its prognostic value is not known. The objective of this study was to analyse {sup 11}C-acetate PET/CT image metrics in relation to survival. All patients undergoing {sup 11}C-acetate PET/CT in one university hospital from 2005 to 2011 due to PSA relapse after previous prostatectomy were retrospectively evaluated. Two groups of patients were compared: those who died from PCa and those who were censored. All previously reported findings of local recurrence, regional or distal lymph node metastases and bone metastases were counted and evaluated regarding {sup 11}C-acetate uptake intensity (SUV{sub max}) and tumour volume. Total tumour volume and total lipogenic activity (TLA, summed SUV{sub max} x TV) were calculated. Survival analysis in the entire study population was followed by Cox proportional hazards ratio (HR) analysis. A total of 121 patients were included, and 22 PCa-specific deaths were recorded. The mean PSA level at the time of PET was 2.69 ± 4.35 ng/mL. The median follow-up of the study population was 79 ± 28 months. PET identified at least one PCa lesion in 53 % of patients. Five-year PCa-specific survival after PET was 80 % and 100 % in patients with a positive and a negative PET scan, respectively (p < 0.001). Time-to-death was linearly correlated with highest SUV{sub max} (r = -0.55, p = 0.01) and nonlinearly with TLA (r = -0.75, p < 0.001). Multivariate analysis showed statistical significance for number of bone metastases (HR 1.74, p = 0.01), tertile of TLA (HR 5.63, p = 0.029) and postoperative Gleason score (HR 1.84, p = 0.045). Malignant {sup 11}C-acetate accumulation measured with PET/CT is a strong predictor of survival in the setting of PSA relapse after prostatectomy. The study provides further evidence for a

    Allogeneic stem cell transplantation (SCT) is curative treatment in patients with acute leukemia and myelodysplastic syndrome. However, recurrent disease is the major cause of treatment failure. Isolated extramedullary relapse (iEMR) after SCT is relatively rare and not well characterized. We performed a retrospective analysis of 566 consecutive patients with acute myeloid leukemia (n = 446) and acute lymphoblastic leukemia (ALL; n = 120) after SCT to study the incidence, risk factors, treatment options, and outcome of iEMR. The 5-year cumulative incidence of bone marrow relapse (BMR) and iEMR was 41.0% and 5.8%, respectively. iEMR occurred significantly later than BMR at 10 and 4 months, respectively (P BMR but did not protect against iEMR. Most patients with iEMR received systemic treatment combined with local radiation and donor lymphocyte infusions when feasible. The 3-year survival after relapse was 8.5% and 30.1% after BMR and iEMR, respectively (P = .002). Patients with a first iEMR continued to have recurrent EMRs, and only a minority progressed to BMR. Second iEMR was also common after first BMR and associated with longer survival than second BMR. iEMR is more frequent in patients with ALL and prior extramedullary disease. It occurs later than BMR and more commonly in patients with chronic GVHD, suggesting less effective graft-versus-leukemia effect in extramedullary sites. Second iEMR is common after a first iEMR but also after a first BMR. Long-term survival is feasible with aggressive treatment.

    To elucidate factors contributing to the effectiveness of allogeneic hematopoietic stem cell transplantation (alloHCT) in high-risk CLL, immune interventions, GvHD and clinical outcome of 77 consecutive patients allografted for CLL were analyzed. Immune modulation (immunosuppression tapering, rituximab-augmented donor lymphocyte infusions) was guided by minimal residual disease (MRD) monitoring and commenced at a median of 91 (22-273) days after alloHCT, resulting in a probability of being event free and MRD-negative 1 year after transplant of 57% (84% in those encountering chronic GvHD). Patients who were event free and MRD-negative at the 12-month landmark had a 4-year PFS of 77% and largely remained durably MRD-negative if MRD clearance had occurred subsequent to immune modulation. Three-year overall survival, PFS, relapse incidence and non-relapse mortality of all 77 patients were 69, 57, 26 and 24%, respectively. Survival was not affected by EBMT risk category but by active disease at alloHCT, which could not be overcome by intensification of conditioning. Twenty-three patients who experienced relapse post alloHCT had a survival of 56% at 2 years after CLL recurrence. In conclusion, MRD-guided immune modulation after alloHCT for high-risk CLL can provide durable MRD clearance in more than half of the patients.

    Patients with locally recurrent adenocarcinoma of the prostate following radiation therapy (RT) present a challenging problem. We prospectively evaluated the use of "high-dose-rate-like" prostate stereotactic body RT (SBRT) salvage for this circumstance, evaluating prostate-specific antigen response, disease-free survival, and toxicity. Between February 2009 and March 2014, 29 patients with biopsy-proven recurrent locally prostate cancer >2 years post-RT were treated. Median prior RT dose was 73.8 Gy and median interval to SBRT salvage was 88 months. Median recurrence Gleason score was 7 (79% was ≥7). Pre-existing RT toxicity >grade 1 was a reason for exclusion. Magnetic resonance imaging-defined prostate volume including any suspected extraprostatic extension, comprising the planning target volume. A total of 34 Gy/5 fractions was given, delivering a heterogeneous, high-dose-rate-like dose-escalation pattern. Toxicities were assessed using Common Terminology Criteria for Adverse Events, version 3.0, criteria. Twenty-nine treated patients had a median 24-month follow-up (range, 3-60 months). A median pre-SBRT salvage baseline prostate-specific antigen level of 3.1 ng/mL decreased to 0.65 ng/mL and 0.16 ng/mL at 1 and 2 years, respectively. Actuarial 2-year biochemical disease-free survival measured 82%, with no local failures. Toxicity >grade 1 was limited to the genitourinary domain, with 18% grade 2 or higher and 7% grade 3 or higher. No gastrointestinal toxicity >grade 1 occurred. Two-year disease-free survival is encouraging, and the prostate-specific antigen response kinetic appears comparable with that seen in de novo patients treated with SBRT, albeit still a preliminary finding. Grade ≥2 genitourinary toxicity was occasionally seen with no obvious predictive factor. Noting that our only brachytherapy case was 1 of the 2 cases with ≥grade 3 genitourinary toxicity, caution is recommended treating these patients. SBRT salvage of post-RT local recurrence

    Non-Hodgkin's lymphoma (NHL) remains the second most common malignant complication in patients with human immunodeficiency virus (HIV) infection. Even though NHL is commonly chemosensitive to primary treatment, failure or relapse still occurs in a large number of patients. We conducted this retrospective study to evaluate the efficacy and safety of gemcitabine, dexamethasone, and cisplatin (GDP) for relapsed or refractory AIDS-related NHL (AIDS-NHL). Forty-eight patients with relapsed or refractory AIDS-NHL were treated with intravenous combination chemotherapy with GDP. The overall objective response rate was 54.1% (95% confidence interval, CI, 40.1-68.3%), with 10 complete responses and 16 partial responses. The 2-year overall survival rate (OS) was 70.8% (95% CI 58.0-83.7%), and the 5-year OS was 41.7% (95% CI 27.7-55.6%). The 2-year progression-free survival rate (PFS) was 37.5% (95% CI 23.8-51.2%), and the 5-year PFS was 25.0% (95% CI 12.8-37.3%). The median progression-free survival was 8.8 months (95% CI 0-20.3 months), and the median overall survival was 40.6 months (95% CI 22.6-58.6 months). Patients with B cell tumors who relapsed but had no B symptoms were clinical stage I/II, had infiltration fewer than two extranodal sites, had CD4⁺ counts >200 cells/μL, and had lactate dehydrogenase (LDH) less than the upper limit of normal benefited from GDP. The level of LDH had a significant impact on the response rate to chemotherapy with GDP (P = 0.015). Myelosuppression was the main side effect; the incidence of grade 3-4 anemia was 8.3%; leukopenia, 37.5%; and thrombocytopenia, 48.3%. Univariate and multivariate analyses were performed to determine variables for OS and PFS. This study confirms that GDP is an effective and safe salvage regimen in relapsed or refractory AIDS-NHL, was associated with modest declines in CD4⁺ lymphocyte counts, and did not promote HIV-1 viral replication.

    Full Text Available Context: Support for non-Hodgkin′s lymphoma (NHL with large cells that is refractory or relapsed after first-line chemotherapy poses a greater therapeutic problem with bone marrow transplant therapy or when old age is a contra-indication for high-dose chemotherapy, especially among developing countries such as Algeria. Aim: To show that the regimen, including gemcitabine, could be more effective in treating elderly patients with diffuse large B-cell lymphoma (DLBCL in relapse / refractory, without complete remission, when compared with the ESHAP (etoposide, cisplatine, solumedrol, aracytine regimen. Materials and Methods: Ninety-six patients in the age group of 60-70 years were volunteers for a prospective randomized single-blind study, carried out for three years. Patients were divided into two groups by the drawing of lots. The first group (GA, n = 48, relapse; n = 27 [56.3%], refractory; n = 21 [43.7%] received treatment with ESHAP protocol and the second one (GB, n = 48, relapse; n = 28 [58%], refractory; n = 20 [42%] with GPD (gemcitabine, dexamethasone, cisplatine protocol. Results: The overall response rates and mean survival at three years were significantly higher among patients subjected to GPD treatment compared with those subjected to ESHAP treatment (63% vs. 55%, P = 0.01 and 20.5% [95% CI 16.5-24.5] vs. 11.8% [8.9-14.6], respectively. Additionally, three-year progression-free and event-free survival rates were 20.5% (16.3-24 and 19.7% (15.9-23.5, respectively, for the GPD regimen and 10.9% (8.2-13.7 and 11.1% (95% CI 8.5-13.7, respectively, for the ESHAP regimen. Moreover, the GPD regimen was associated with improving overall survival (RR=2.02, 95% CI 1.59-2.56; P = 0.000, event-free survival (2.03, 1.64-2.52; P < 0.001 and progression-free survival (1.86, 1.46-2.37; P < 0.001.

    Concomitant radiotherapy (5FU -MMC) was proved to be useful in locally advanced anal canal carcinoma. Nevertheless. it remains 30 % of failures after this conservative treatment. The tolerance and efficiency of a neo-adjuvant chemotherapy (5-FU-CDDP) were validated by a phase II trial including 80 patients, which obtained 73 % of colostomy free survival and 70 % of relapse free survival at 3-year follow-up. its usefulness is studied in an ongoing phase III trial, as well as the dose escalation of the boost, from 15 Gy to 25-25 Gy. The results of the 101 first included patients are studied by an intermediate analyze. In July 2003, 222 patients were enrolled by 33 investigating centres out of the 350 planned patients until the end of the trial in December 2004. (author)

    Relapse remains the major cause of treatment failure in children with high-risk acute lymphoblastic leukaemia (ALL) undergoing allogeneic haematopoietic stem-cell transplantation (allo-SCT). Prognosis is considered dismal but data on risk factors and outcome are lacking from prospective studies. We analysed 242 children with recurrence of ALL after first allo-SCT enrolled in the Berlin-Frankfurt-Munster (BFM) ALL-SCT-BFM 2003 and ALL-SCT-BFM international 2007 studies. Median time from allo-SCT to relapse was 7·7 months; median follow-up from relapse after allo-SCT until last follow-up was 3·4 years. The 3-year event-free survival (EFS) was 15% and overall survival (OS) was 20%. The main cause of death was disease progression or relapse (86·5%). The majority of children (48%) received salvage therapy without second allo-SCT, 26% of the children underwent a second allo-SCT and 25% received palliative treatment only. In multivariate analyses, age, site of relapse, time to relapse and type of salvage therapy were identified as significant prognostic factors for OS and EFS, whereas factors associated with first SCT were not statistically significant. Combined approaches incorporating novel immunotherapeutic treatment options and second allo-SCT hold promise to improve outcome in children with post allo-SCT relapse. © 2017 John Wiley & Sons Ltd.

    Despite the dramatic improvement in the overall survival for patients diagnosed with Wilms’ tumor (WT), the outcomes for those that experience relapse have remained disappointing. We describe the outcomes of 253 patients with relapsed WT who received high-dose chemotherapy (HDT) followed by autologous hematopoietic stem cell transplant (HCT) between 1990 and 2013, and reported to the Center for International Blood and Marrow Transplantation Research (CIBMTR). The 5-year estimates for event free survival (EFS) and overall survival (OS) were 36% (95% CI; 29 – 43%) and 45% (95% CI; 38 – 51%) respectively. Relapse of primary disease was the cause of death in 81% of the population. EFS, OS, relapse and transplant-related mortality (TRM) showed no significant differences when broken down by disease status at transplant, time from diagnosis to transplant, year of transplant or conditioning regimen. Our data suggest that HDT followed by autologous HCT for relapsed WT is well tolerated and outcomes are similar to those reported in the literature. Since attempts to conduct a randomized trial comparing maintenance chemotherapy with consolidation versus high-dose chemotherapy followed by stem cell transplant have failed, one should balance the potential benefits with the yet unknown long-term risks. Since disease recurrence continues to be the most common cause of death, future research should focus on the development of consolidation therapies for those patients achieving complete response to therapy.

    A randomized trial demonstrated that capecitabine is at least as effective as fluorouracil in the adjuvant treatment of patients with locally advanced rectal cancer. However, not all patients receive all planned cycles of chemotherapy. Therefore it is of interest how complete or partial administration of chemotherapy influences oncological outcome. A post hoc analysis of a trial with 401 randomized patients, nine being excluded because of missing data, was performed. 392 patients (197 - capecitabine, 195 - fluorouracil) could be analyzed regarding the number of administered adjuvant chemotherapy cycles. In the subgroup of 361 patients with an overall survival of at least six months, five-year overall and disease-free survival were analyzed in respect to completion (complete vs. incomplete) of chemotherapy cycles. Survival rates and curves were calculated and compared using the log-rank test. The effect of completion of chemotherapy was adjusted for relevant confounding factors. Two hundred fifty-one (64.0%) of analyzed patients received all postoperative scheduled cycles. Five-year overall survival was significantly better in these patients compared to the incomplete group (76.0 vs. 60.6%, p cycles. Five-year overall survival was also significantly better than in the incomplete group (76.0 vs. 66.4%, p = 0.0073). Five-year disease free survival was numerically better (64.9 vs. 58.7%, p = 0.0646; HR [not all cycles vs. all cycles] = 1.42 95% CI: [0.98, 2.07]). Cox regression models show a non-significant better OS (p = 0.061) and DFS (p = 0.083), if chemotherapy cycles were administered completely. Complete administration of chemotherapy cycles was associated with improved five-year overall and disease-free survival in patients with locally advanced rectal cancer.

    The treatment of relapsed chronic lymphocytic leukemia (CLL) has resulted in few durable remissions. Bruton's tyrosine kinase (BTK), an essential component of B-cell-receptor signaling, mediates interactions with the tumor microenvironment and promotes the survival and proliferation of CLL cells. We conducted a phase 1b-2 multicenter study to assess the safety, efficacy, pharmacokinetics, and pharmacodynamics of ibrutinib (PCI-32765), a first-in-class, oral covalent inhibitor of BTK designed for treatment of B-cell cancers, in patients with relapsed or refractory CLL or small lymphocytic lymphoma. A total of 85 patients, the majority of whom were considered to have high-risk disease, received ibrutinib orally once daily; 51 received 420 mg, and 34 received 840 mg. Toxic effects were predominantly grade 1 or 2 and included transient diarrhea, fatigue, and upper respiratory tract infection; thus, patients could receive extended treatment with minimal hematologic toxic effects. The overall response rate was the same in the group that received 420 mg and the group that received 840 mg (71%), and an additional 20% and 15% of patients in the respective groups had a partial response with lymphocytosis. The response was independent of clinical and genomic risk factors present before treatment, including advanced-stage disease, the number of previous therapies, and the 17p13.1 deletion. At 26 months, the estimated progression-free survival rate was 75% and the rate of overall survival was 83%. Ibrutinib was associated with a high frequency of durable remissions in patients with relapsed or refractory CLL and small lymphocytic lymphoma, including patients with high-risk genetic lesions.

    Full Text Available E1697 was a phase III trial of adjuvant interferon (IFN-α2b for one month (Arm B versus observation (Arm A in patients with resected melanoma at intermediate risk. We evaluated the levels of candidate serum cytokines, the HLA genotype, polymorphisms of CTLA4 and FOXP3 genes and the development of autoantibodies for their association with relapse free survival (RFS in Arm A and Arm B among 268 patients with banked biospecimens.ELISA was used to test 5 autoantibodies. Luminex/One Lambda LABTypeRSSO was used for HLA Genotyping. Selected CTLA4 and FOXP3 Single nucleotide polymorphisms (SNPs and microsatellites were tested for by polymerase chain reaction (PCR. Sixteen serum cytokines were tested at baseline and one month by Luminex xMAP multiplex technology. Cox Proportional Hazards model was applied and the Wald test was used to test the marginal association of each individual marker and RFS. We used the Lasso approach to select the markers to be included in a multi-marker Cox Proportional Hazards model. The ability of the resulting models to predict one year RFS was evaluated by the time-dependent ROC curve. The leave-one-out method of cross validation (LOOCV was used to avoid over-fitting of the data.In the multi-marker modeling analysis conducted in Arm B, one month serum IL2Rα, IL-12p40 and IFNα levels predicted one year RFS with LOOCV AUC = 82%. Among the three markers selected, IL2Rα and IFNα were the most stable (selected in all the cross validation cycles. The risk score (linear combination of the 3 markers separated the RFS curves of low and high risk groups well (p = 0.05. This model did not hold for Arm A, indicating a differential marker profile in Arm B linked to the intervention (adjuvant therapy.Early on-treatment proinflammatory serum markers (IL2Rα, IL-12p40, IFNα significantly predict RFS in our cohort of patients treated with adjuvant IFN-α2b and warrant further study.

    Purpose: To study the use of the year of therapy as an independent predictor of outcomes, serving as a proxy for time-related changes in therapy and tumor factors in the treatment of prostate cancer. Accounting for these changes would facilitate the retrospective comparison of outcomes for patients treated in different periods. Methods and Materials: Nine institutions combined data on 4,537 patients with Stages T1 and T2 adenocarcinoma of the prostate who had a pretherapy prostate-specific antigen (PSA) level and biopsy Gleason score, and who had received ≥60 Gy external beam radiotherapy without neoadjuvant androgen deprivation or planned adjuvant androgen deprivation. All patients were treated between 1986 and 1995. Two groups were defined: those treated before 1993 (Yr ≤92) vs. 1993 and after (Yr ≥93). Patients treated before 1993 had their follow-up truncated to make the follow-up time similar to that for patients treated in 1993 and after. Therefore, the median follow-up time was 6.0 years for both groups (Yr ≤92 and Yr ≥93). Two separate biochemical failure endpoints were used. Definition A consisted of the American Society for Therapeutic Radiology Oncology endpoint (three PSA rises backdated, local failure, distant failure, or hormonal therapy). Definition B consisted of PSA level greater than the current nadir plus two, local failure, distant failure, or hormonal therapy administered. Multivariate analyses for factors affecting PSA disease-free survival (PSA-DFS) rates using both endpoints were performed for all cases using the following variables: T stage (T1b, T1c, T2a vs. T2b, T2c), pretreatment PSA (continuous variable), biopsy Gleason score (continuous variable), radiation dose (continuous variable), and year of treatment (continuous variable). The year variable (defined as the current year minus 1960) ranged from 26 to 35. To evaluate the effect of radiation dose, the multivariate analyses were repeated with the 3,897 cases who had received

    In this viewpoint we highlight and discuss some recent local and regional level advances in tobacco control in Aotearoa/New Zealand. In this country a wide range of local actors are helping drive smokefree and tobacco-free policies, with an increasing presence of businesses in this field. There has been progress in the areas of smokefree dining, large outdoor worksites and ski fields, and parts of downtown areas such as squares and streets. In 2015 and 2016, three councils (Palmerston North, Napier and Hastings) have used pavement lease policies and bylaws to start introducing an element of requirement into smokefree outdoor dining. Elsewhere (eg, Rotorua, Ashburton, Westland and Christchurch) significant smokefree outdoor dining moves have been made by, or in conjunction with, local councils. Tobacco-free retailing continues to expand, particularly in Northland. In the absence of meaningful central government action on smokefree places in the last decade (despite the Smokefree 2025 goal), local activity is leading the way. It is particularly important in providing models for smokefree outdoor hospitality areas, where smoking normalisation and relapse are significant health risks. Nevertheless, there is a need for the local smokefree and tobacco-free activity to be nationally evaluated, particularly for assessing the prevalence of smoking in areas covered by 'smokefree' policies. Action by central government could help local actors by providing a more definite legislative basis for bylaws, by minimum outdoor smokefree laws and by the funding of effective tobacco control mass media.

    Full Text Available Colorectal cancer (CRC is one of the leading causes of cancer mortality. Metastasis remains the primary cause of CRC death. Predicting the possibility of metastatic relapse in early-stage CRC is of paramount importance to target therapy for patients who really need it and spare those with low-potential of metastasis. Ninety-six stage II CRC cases were stratified using high-resolution array comparative genomic hybridization (aCGH data based on a predictive survival algorithm and supervised clustering. All genes included within the resultant copy number aberrations were each interrogated independently at mRNA level using CRC expression datasets available from public repositories, which included 1820 colon cancers, and 167 normal colon tissues. Reduced mRNA expression driven by copy number losses and increased expression driven by copy number gains revealed 42 altered transcripts (29 reduced and 13 increased transcripts associated with metastatic relapse, short disease-free or overall survival, and/or epithelial to mesenchymal transition (EMT. Resultant genes were classified based on gene ontology (GO, which identified four functional enrichment groups involved in growth regulation, genomic integrity, metabolism, and signal transduction pathways. The identified 42 genes may be useful for predicting metastatic relapse in stage II CRC. Further studies are necessary to validate these findings.

    The purpose of this article is to better understand the utility of smoking in pubs/bars and nightclubs and explore perceptions of how smoke-free policies might influence smoking behavior. Qualitative focus group methodology was used involving young social smokers and older regular smokers. Pubs/bars and nightclubs were valued as the few remaining indoor public places where people could relax and smoke. These venues were perceived to provide encouragement for smoking more cigarettes by increasing smoking rate and facilitating smoking relapse. For young social smokers, smoking provided an opportunity to be part of a "cool" in-group. Older regular smokers felt pubs/bars provided strong cues for smoking relapse. Smokers felt they would adapt to smoke-free policies and expected these policies to reduce their smoking or assist quitting. Smoke-free policies in pubs/bars and nightclubs may assist smokers to quit and make it less likely that young social smokers will progress to regular smoking.

    Purpose: The aim of this retrospective case-matching study was to compare the treatment outcomes and acute toxicity of preoperative radiotherapy (RT) with capecitabine vs. preoperative RT with intermittent 5-fluorouracil (5-FU) infusion, leucovorin, and mitomycin C in rectal cancer. Methods and Materials: We matched 34 patients who were treated with preoperative concurrent capecitabine and 50 Gy of RT by their clinical T stage (T3 or T4) and the tumor location (≤7 cm or >7 cm from the anal verge) with another 68 patients who were treated with preoperative intermittent 5-FU infusion, leucovorin, mitomycin C, and 50 Gy of RT for a comparison of the pathologic tumor response, local control, distant failure, and survival rates. Results: The pathologic complete response rate was 21% with capecitabine and 18% with 5-FU and leucovorin (p = 0.72). The rate of T downstaging after chemoradiation was 59% for both groups. The rate of sphincter-sparing resection was 38% after capecitabine plus RT and 43% after 5-FU plus RT (p = 0.67). At 3 years, there was no significant difference in the local control rate (93% for capecitabine and 92% for 5-FU and leucovorin), relapse-free rate (74% for capecitabine and 73% for 5-FU and leucovorin), or disease-specific survival rate (86% for capecitabine and 77% for 5-FU and leucovorin). The acute toxicity profile was comparable, with little Grade 3 and 4 toxicity. Conclusions: When administered with concurrent preoperative RT, both capecitabine and intermittent 5-FU infusion with leucovorin modulation provided comparable pathologic tumor response, local control, relapse-free survival, and disease-specific survival rates in rectal cancer.

    Purpose: To evaluate the outcomes of patients with localized orbital marginal zone B-cell lymphoma of the mucosa-associated lymphoid tissue (MALT lymphoma) who were treated with radiotherapy (RT). Methods and Materials: We retrospectively reviewed the records of 46 patients who were treated with RT for pathologically confirmed localized stage IE marginal zone B-cell lymphoma of MALT. The radiation dose ranged from 21.6 to 45 Gy (median, 30.6 Gy) at 1.8-2.0 Gy per fraction. Median follow-up duration was 32.3 months (range, 3.1-113.6 months). Results: Forty-three patients (93%) achieved complete remission (CR), and three patients (7%) achieved partial remission (PR). Five-year relapse-free survival, cause-specific survival, and overall survival were 93%, 100%, and 100%, respectively. Among the patients with CR, two had recurrence at three sites. One patient relapsed locally and was successfully salvaged with reirradiation. The other patient relapsed in a distant site and was successfully treated with six cycles of CHOP chemotherapy. Late complications were noted in four patients. Two patients developed cataracts at 26 and 37 months after completion of RT. The other two patients developed nasolacrimal duct obstructions at 4 and 11 months after completion of RT. Conclusion: Our study showed that a modest dose of RT is an excellent treatment modality with low complication and recurrence rates. We suggest that a dose of 30.6 Gy is tolerable and sufficient for treating orbital MALT lymphoma. Even following recurrence, successful salvage is possible with RT or chemotherapy.

    Our aim was to evaluate the clinical value of splenectomy as a treatment for relapsed hemophagocytic lymphohistiocytosis (HLH) of unknown cause in adults. We retrospectively reviewed the clinical data from medical records of 19 adults with relapsed HLH of unknown cause treated with splenectomy in our institution from June 2007 to March 2014. To rule out possible underlying diseases, including infection, autoimmune disease, neoplasms, and primary HLH, the patients had undergone examinations including F18 fluoro-2-deoxyglucose positron emission tomography/computed tomography, HLH-associated gene defects, and lymph node biopsies. Twelve patients (63.2%) achieved partial responses (PR), whereas seven patients (36.8%) had no response (NR) prior to splenectomy. Infection and hemorrhage were the main complications of splenectomy. Eighteen cases were evaluable after follow-up. Seven cases with histopathologic diagnoses of lymphoma had received chemotherapy, four of whom had achieved complete responses (CR), one PR, and two NR. Maintenance treatment was ceased 2 or 3 months after splenectomy in the other 11 cases, five of whom had CR, four PR, and two NR. Eleven of 18 cases (61.1%) survived with a median follow-up of 25 months (range 3-79 months) for survivors. Twelve- and 36-month progression-free survival rates were 48 and 24%, respectively; 12- and 36-month overall survival rates were 57 and 25%, respectively. Median survival time was 22 months. Our results indicate splenectomy may be an effective means of diagnosis and treatment of relapsed HLH of unknown cause. Further study is required to establish the mechanism and value of splenectomy in this disease.

    This retrospective study analyzes the safety and feasibility of concurrent chemoradiotherapy (CRT) in adjuvant treatment of soft tissue sarcoma (STS). A total of 158 patients with STS were retrospectively analyzed. Anthracycline-based computed tomography was performed in high-risk patients. Acute radiotherapy toxicity and chemotherapy-related toxicity were assessed according to the Common Terminology Criteria for Adverse Events 4.0; late radiotherapy toxicity was recorded according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer criteria. Fifty-four (34.2%) patients received CRT. Mean follow up was 5.4 years (range .2-21.1 years). Local DFS-recurrence-free survival, distant DFS-relapse-free survival, and overall survival were 79.1%, 76.4%, and 64.6%, respectively, at last follow-up. Leukopenia occurred in 11.4% of patients. Skin acute toxicity developed in 60.1% of patients and determined interruption of radiotherapy treatment in 19 (12%) patients. Nineteen patients (12%) experienced moderate fibrosis (grade 2). Mild and moderate joint stiffness was recorded in 16 (10.1%) patients. Size ≥5 cm was the only predictor of local recurrence at multivariate analysis (hazard ratio [HR] 9.65, 95% confidence interval [CI] 1.28-72.83, p = .028). Age and stage resulted as independent distant relapse predictors (HR 4.77, 95% CI 1.81-12.58, p = .002 and HR 4.83, CI 1.41-16.57, p = .012, respectively). At Cox regression univariate analysis, Karnofsky Performance Status, size, and stage were significant survival predictors (HR 2.23, 95% CI 1.02-4.87, p = .045; HR 2.88, 95% CI 1.10-7.52, p = .031; HR 2.59, 95% CI 1.11-6.04, p = .028). Concurrent CRT is a well-tolerated treatment option with no additional toxicity compared to exclusive radiotherapy or sequential CRT.

    Purpose: To evaluate the safety, feasibility, side-effect profile, and proof of concept of external beam radiation therapy (EBRT) with or without a brachytherapy (BT) boost for salvage of exclusive local failure after primary EBRT for prostate cancer. Methods and Materials: Fourteen patients with presumed exclusive local recurrence after primary EBRT with or without BT were considered eligible for reirradiation. The median normalized total dose in 2-Gy fractions (NTD_2_G_y, α/β ratio = 1.5 Gy) was 74 Gy (range, 66-98.4 Gy) at first irradiation. Median time between the first irradiation and the reirradiation was 6.1 years (range, 4.7-10.2 years). Results: Between 2003 and 2008 salvage treatment was delivered with a median NTD_2_G_y of 85.1 Gy (range, 70-93.4) to the prostate with EBRT with (n=10) or without (n=4) BT. Androgen deprivation was given to 12 patients (median time of 12 months). No grade ≥3 toxicity was observed during and within 6 weeks after RT. After a median follow-up of 94 months (range, 48-172 months) after salvage RT, 5-year grade ≥3 genitourinary and gastrointestinal toxicity-free survival figures were 77.9% ± 11.3% and 57.1% ± 13.2%, respectively. Four patients presented with combined grade 4 genitourinary/gastrointestinal toxicity. The 5-year biochemical relapse-free, local relapse-free, distant metastasis-free, and cancer-specific survival rates were 35.7% ± 12.8%, 50.0% ± 13.4%, 85.7% ± 9.4%, and 100%, respectively. Conclusion: Salvage whole-gland reirradiation for patients with a suspicion of exclusive local recurrence after initial RT may be associated with a high rate of severe radiation-induced side effects and poor long-term biochemical and local control.

    Background Even though Hodgkin lymphoma is a highly curable disease, some of the patients have either a refractory disease or experience a relapse following a successful primary therapy. Durable responses and remissions in patients with relapsed or refractory disease may be achieved in approximately one-half with salvage chemotherapy followed by high dose chemotherapy (HDT) and autologous hematopoietic cell rescue (SCT). On the other hand, patients who relapse after HDT and autologous SCT or those who have failed at least two prior multi-agent chemotherapy regimens and are not candidates for HDT have limited treatment options. Conclusions A new treatment option in this population is an immunotoxin Brentuximab vedotin composed of a CD30 directed antibody linked to the antitubulin agent monomethyl auristatin E. It has demonstrated a substantial effectiveness and an acceptable toxicity. In the pivotal study, the overall response rate was 75% with 34% of complete remissions. The median durations of response were 20.5 and 6.7 months for those with complete remission and all responding patients, respectively. The median overall survival was 40.5 months (3-years overall survival 54%) and the median progression-free survival 9.3 months. The most common non-hematologic toxicities were peripheral sensory neuropathy, nausea, and fatigue while the most common severe side effects were neutropenia, thrombocytopenia, anemia, and peripheral sensory neuropathy.

    Purpose: To evaluate the prognostic value of the posttreatment TNM stage as a predictor of outcome in locally advanced rectal cancers treated with preoperative chemotherapy and radiotherapy. Methods and materials: Between 1993 and 2000, 128 patients with tethered (103) or fixed (25) rectal cancers were treated with 50 Gy preoperative pelvic radiotherapy and two cycles of concurrent 5-fluorouracil infusion (20 mg/kg/d) and leucovorin (200 mg/m 2 /d) chemotherapy on Days 1-4 and 22-25 and a single bolus mitomycin C injection (8 mg/m 2 ) on Day 1. Of the 128 patients, 111 had Stage T3 and 17 Stage T4 according to the rectal ultrasound or CT findings and clinical evaluation. All 128 patients underwent surgery 8 weeks after chemoradiotherapy. Postoperatively, the disease stage was determined according to the surgical and pathologic findings using the American Joint Committee on Cancer TNM staging system. Results: Of the 128 patients, 32 had postchemoradiotherapy (pCR) Stage 0 (T0N0M0), 37 pCR Stage I, 26 pCR Stage II, 28 pCR Stage III, and 5 pCR Stage IV disease. Of the 128 patients, 79 had pCR Stage T0-T2, 35 pCR Stage T3, and 14 pCR Stage T4. The rate of T stage downstaging was 66% (84 of 128). Of the 128 patients, 25% achieved a pathologic complete response, and 31 (24%) had positive nodal disease. Lymphovascular or perineural invasion was found in 13 patients (10%). The 5-year disease-specific survival rate was 97% for pCR Stage 0, 88% for pCR Stage I, 74% for pCR Stage II, 44% for pCR Stage III, and 0% for pCR Stage IV (p = 0.0000059). The 5-year relapse-free survival rate was 97% for pCR Stage 0, 80% for pCR Stage I, 72% for pCR Stage II, 42% for pCR Stage III, and 0% for pCR Stage IV (p < 0.000001). In univariate analysis, the pretreatment tumor status (fixed vs. tethered tumors), the pCR TNM stage, T stage downstaging, pathologic T4 tumors, node-positive disease after chemoradiotherapy, and lymphovascular or perineural invasion were statistically significant

    The phase 3 ENDEAVOR trial was a head-to-head comparison of two proteasome inhibitors in patients with relapsed or refractory multiple myeloma. Progression-free survival was previously reported to be significantly longer with carfilzomib administered in combination with dexamethasone than with bortezomib and dexamethasone in an interim analysis. The aim of this second interim analysis was to compare overall survival between the two treatment groups. ENDEAVOR was a phase 3, open-label, randomised controlled trial in patients with relapsed or refractory multiple myeloma. Patients were recruited from 198 hospitals and outpatient clinics in 27 countries in Europe, North America, South America, and the Asia-Pacific region. Patients were aged 18 years or older, had relapsed or refractory multiple myeloma, and had received between one and three previous lines of therapy. Patients were randomly assigned (1:1) to receive carfilzomib and dexamethasone (carfilzomib group) or bortezomib and dexamethasone (bortezomib group) through a blocked randomisation scheme (block size of four), stratified by International Staging System stage, previous lines of treatment, previous proteasome inhibitor therapy, and planned route of bortezomib delivery if assigned to the bortezomib group. Carfilzomib (20 mg/m 2 on days 1 and 2 of cycle 1; 56 mg/m 2 thereafter) was given as a 30-min intravenous infusion on days 1, 2, 8, 9, 15, and 16 of 28-day cycles; bortezomib (1·3 mg/m 2 ) was given as an intravenous bolus or subcutaneous injection on days 1, 4, 8, and 11 of 21-day cycles. Dexamethasone (20 mg oral or intravenous infusion) was given on days 1, 2, 8, 9, 15, 16, 22, and 23 in the carfilzomib group and on days 1, 2, 4, 5, 8, 9, 11, and 12 in the bortezomib group. The primary endpoint of ENDEAVOR, progression-free survival, has been previously reported. A stratified log-rank test was used to compare overall survival between treatment groups for this prospectively planned second interim

    Background Despite all the advances in the treatment of childhood acute lymphoblastic leukemia, central nervous system relapse remains an important obstacle to curing these patients. This study analyzed the incidence of central nervous system relapse and the risk factors for its occurrence in children and adolescents with acute lymphoblastic leukemia. Methods This study has a retrospective cohort design. The studied population comprised 199 children and adolescents with a diagnosis of acute lymphoblastic leukemia followed up at Hospital das Clinicas, Universidade Federal de Minas Gerais (HC-UFMG) between March 2001 and August 2009 and submitted to the Grupo Brasileiro de Tratamento de Leucemia da Infância - acute lymphoblastic leukemia (GBTLI-LLA-99) treatment protocol. Results The estimated probabilities of overall survival and event free survival at 5 years were 69.5% (± 3.6%) and 58.8% (± 4.0%), respectively. The cumulative incidence of central nervous system (isolated or combined) relapse was 11.0% at 8 years. The estimated rate of isolated central nervous system relapse at 8 years was 6.8%. In patients with a blood leukocyte count at diagnosis ≥ 50 x 109/L, the estimated rate of isolated or combined central nervous system relapse was higher than in the group with a count 50 x 109/L at diagnosis seems to be a significant prognostic factor for a higher incidence of central nervous system relapse in childhood acute lymphoblastic leukemia.

    The presence of certain high-risk cytogenetic abnormalities, such as translocations (4;14) and (14;16) and deletion (17p), are known to have a negative impact on survival in multiple myeloma (MM). The phase 3 study ASPIRE (N = 792) demonstrated that progression-free survival (PFS) was significantly improved with carfilzomib, lenalidomide, and dexamethasone (KRd), compared with lenalidomide and dexamethasone (Rd) in relapsed MM. This preplanned subgroup analysis of ASPIRE was conducted to evaluate KRd vs Rd by baseline cytogenetics according to fluorescence in situ hybridization. Of 417 patients with known cytogenetic risk status, 100 patients (24%) were categorized with high-risk cytogenetics (KRd, n = 48; Rd, n = 52) and 317 (76%) were categorized with standard-risk cytogenetics (KRd, n = 147; Rd, n = 170). For patients with high-risk cytogenetics, treatment with KRd resulted in a median PFS of 23.1 months, a 9-month improvement relative to treatment with Rd. For patients with standard-risk cytogenetics, treatment with KRd led to a 10-month improvement in median PFS vs Rd. The overall response rates for KRd vs Rd were 79.2% vs 59.6% (high-risk cytogenetics) and 91.2% vs 73.5% (standard-risk cytogenetics); approximately fivefold as many patients with high- or standard-risk cytogenetics achieved a complete response or better with KRd vs Rd (29.2% vs 5.8% and 38.1% vs 6.5%, respectively). KRd improved but did not abrogate the poor prognosis associated with high-risk cytogenetics. This regimen had a favorable benefit-risk profile in patients with relapsed MM, irrespective of cytogenetic risk status, and should be considered a standard of care in these patients.

    Purpose: To compare postirradiation biochemical disease-free survival using the American Society of Therapeutic Radiology and Oncology (ASTRO) Consensus or elevation of postirradiation prostate-specific antigen (PSA) level beyond 1 ng/mL as an endpoint and correlate chemical failure with subsequent appearance of clinically detected local recurrence or distant metastasis. Methods and Materials: Records of 466 patients with histologically confirmed adenocarcinoma of the prostate treated with irradiation alone between January 1987 and December 1995 were analyzed; 339 patients were treated with bilateral 120 deg. arc rotation and, starting in 1992, 117 with three-dimensional conformal irradiation. Doses were 68-77 Gy in 1.8 to 2 Gy daily fractions. Minimum follow-up is 4 years (mean, 5.5 years; maximum, 9.6 years). A chemical failure was recorded using the ASTRO Consensus or when postirradiation PSA level exceeded 1 ng/mL at any time. Clinical failures were determined by rectal examination, radiographic studies, and, when clinically indicated, biopsy. Results: Six-year chemical disease-free survival rates using the ASTRO Consensus according to pretreatment PSA level for T1 tumors were: ≤4 ng/mL, 100%; 4.1-20 ng/mL, 80%; and >20 ng/mL, 50%. For T2 tumors the rates were: ≤4 ng/mL, 91%; 4.1-10 ng/mL, 81%; 10.1-20 ng/mL, 55%; 20.1-40 ng/mL, 63%; and >40 ng/mL, 46%. When postirradiation PSA levels higher than 1 ng/mL were used, the corresponding 6-year chemical disease-free survival rates for T1 tumors were 92% for pretreatment PSA levels of ≤4 ng/mL, 58-60% for levels of 4.1-20 ng/mL, and 30% for levels >20 ng/mL. For T2 tumors, the 6-year chemical disease-free survival rates were 78% in patients with pretreatment PSA levels of 4-10 ng/mL, 45% for 10.1-40 ng/mL, and 25% for >40 ng/mL. Of 167 patients with T1 tumors, 30 (18%) developed a chemical failure, 97% within 5 years from completion of radiation therapy; no patient has developed a local recurrence or distant

    Solitary plasmacytoma (SP) is a rare plasma cell dyscrasia characterized by the presence of bone or extramedullary plasma cell tumors. The treatment of choice is local radiotherapy (R/T) ± surgical excision. The role of adjuvant chemotherapy (C/T) or novel agents (NA) is uncertain. Data related to prognostic factors are inconclusive. Herein, we describe the clinical features, survival and prognosis of 97 consecutive patients, 65 with bone SP (SBP), and 32 with extramedullary SP (SEP), diagnosed and treated in 12 Greek Myeloma Centers. Objective response rate (≥PR) and complete response (CR) was 91.8% and 61.9%, respectively, and did not differ between the 2 groups. Overall, 38 patients relapsed or progressed to multiple myeloma (MM). After a median follow-up of 60 months, 5 and 10-year overall survival (OS) probability was 92% and 89% in SEP and 86% and 69% in SBP, respectively (P = 0.2). The 5- and 10-year MM-free survival (MMFS) probability was 90% and 70% for patients with SEP vs. 59% and 50% for patients with SBP, respectively (P = 0.054). Overall, the 5- and 10-year OS probability, plasmacytoma relapse-free survival (PRFS), progression-free survival and MMFS was 84% and 78%, 72% and 58%, 58% and 43%, and 70% and 59%, respectively. In the multivariate analysis, prolonged PRFS and young age were positive predictors of OS. Achievement of CR was the only positive predictor of PRFS. Immunoparesis was the only negative predictor of progression to MM. The addition of C/T or NA-based treatment increased toxicity without offering any survival advantage over R/T. © 2014 Wiley Periodicals, Inc.

    Whilst many patients treated with breast conservation undergo re-excision(s) to obtain clear margins, the relationship between clear margins and local recurrence remains unclear. We aimed to determine the impact of final pathological margin status on local recurrence and other breast cancer outcomes. Our study cohort consisted of 755 consecutive patients treated with breast conservation between January 1984 and December 1995. Pathology reports were available for review in 681subjects (90%). Patients were stratified into 8 groups based on final pathological margin status: 1) negative (>3mm, n = 307), close [further divided into two groups 2) >0 1< 2mm, (n = 67)], 4) positive (n= 79), 5) indeterminate (n= 144), 6) low grade DCIS at the margin (n= 3), 7) high grade DCIS at the margin (n= 23) and 8) LCIS at the margin (n= 4). There were no differences between the groups based on histology, T size, grade, LN positivity or total radiation dose. At a median follow-up of 71 months, the breast relapse free survival (BRFS) was 97%, the distant metastasis free survival (DMFS) 78% and the overall survival (OS) 86%, for the entire cohort. There were no statistically significant differences between the negative, close, and positive groups in terms of BRFS: 96% vs. 94% vs. 93% (p=0.59), MFS: 98% vs. 97% vs. 98% (p=0.87) or OS: 84%vs. 85% vs. 86% (p=0.78). Although not statistically significant, the presence of EIC, in the context of close or positive margins, impacted adversely upon local and overall disease free survival. Patients undergoing breast conservation carry a lifelong risk of local recurrence. It is still not clear whether obtaining a radical margin decreases this risk. Tissue microarray analysis will be performed to further elucidate the causes of ipsilateral recurrence at a molecular and genetic level

    The aim of this paper is to describe a four health-state, semi-Markov model structure with health states defined by initiation of subsequent treatment, designed to make best possible use of the data available from a phase 2 clinical trial. The approach is illustrated using data from a sub-group of patients enrolled in a phase 2 clinical trial of olaparib maintenance therapy in patients with platinum-sensitive relapsed ovarian cancer and a BRCA mutation (NCT00753545). A semi-Markov model was developed with four health states: progression-free survival (PFS), first subsequent treatment (FST), second subsequent treatment (SST), and death. Transition probabilities were estimated by fitting survival curves to trial data for time from randomization to FST, time from FST to SST, and time from SST to death. Survival projections generated by the model are broadly consistent with the outcomes observed in the clinical trial. However, limitations of the trial data (small sample size, immaturity of the PFS and overall survival [OS] end-points, and treatment switching) create uncertainty in estimates of survival. The model framework offers a promising approach to evaluating cost-effectiveness of a maintenance therapy for patients with cancer, which may be generalizable to other chronic diseases.

    Aim: To evaluate the impact of staging FDG PET-CT on the initial management of patients with locally advanced cervical carcinoma (LACC) and any prognostic variables predicting survival. Materials and methods: Retrospective analysis of consecutive patients undergoing FDG PET-CT for staging of LACC in a single tertiary referral centre, between April 2008 and August 2011. Comparison was made between MRI and PET-CT findings and any subsequent impact on treatment intent or radiotherapy planning was evaluated. Results: Sixty-three patients underwent FDG PET-CT for initial staging of LACC. Major impact on management was found in 20 patients (32%), a minor impact in five (8%), and no impact in 38 (60%). In those patients where PET-CT had a major impact, 12 had more extensive local nodal involvement, five had occult metastatic disease, two had synchronous tumours, and one patient had equivocal lymph nodes on MRI characterized as negative. PET-positive nodal status at diagnosis was found to be a statistically significant predictor of relapse-free survival (p < 0.05). Conclusion: Staging FDG PET-CT has a major impact on the initial management of approximately one-third of patients with LACC by altering treatment intent and/or radiotherapy planning. PET-defined nodal status is a poor prognostic indicator. - Highlights: • Cervical carcinoma is one of the commonest cancers in women worldwide. • Locally advanced cervical carcinoma is usually treated with chemo-radiotherapy. • FDG PET-CT can have a major impact on management in up to one-third of patients. • It may alter treatment intent or radiotherapy-planning by detecting occult disease. • PET nodal status at diagnosis is an important predictor of relapse-free survival

    Full Text Available Early recurrence (ER after completion of therapeutic regimen in advanced-stage ovarian cancer is a challenging clinical situation. Patients are perceived as invariably having a poor prognosis. We investigated the possibility of defining different prognostic subgroups and the parameters implicated in prognosis of ER patients.We analyzed a multi-centric database of 527 FIGO stage IIIC and IV ovarian cancer patients. We defined patients relapsing within 12 months as ER and investigated using Cox logistic regression the prognostic factors in ER group. We subsequently divided ER patients into good and poor prognosis groups according to a lower or higher overall survival (OS at 12 months after relapse and determined parameters associated to poor prognosis.The median follow up was 49 months. One hundred and thirty eight patients recurred within 12 months. OS and Disease Free Survival (DFS were 24.6 and 8.6 months, respectively, in this group of patients. Among the ER patients, 73 had a poor prognosis with an OS after relapse below 12 months (mean OS = 5.2 months and 65 survived after one year (mean OS = 26.9 months. Residual disease (RD after debulking surgery and mucinous histological subtype negatively impacted prognosis (HR = 1.758, p = 0.017 and HR = 8.641, p = 0.001 respectively. The relative risk of death within 12 months following relapse in ER patients was 1.61 according to RD status. However, RD did not affect DFS (HR = 0.889, p = 0.5.ER in advanced-stage ovarian cancer does not inevitably portend a short-term poor prognosis. RD status after initial cytoreduction strongly modulates OS, that gives additional support to the concept of maximum surgical effort even in patients who will experience early recurrence. The heterogeneity in outcomes within the ER group suggests a role for tumor biology in addition to classical clinical parameters.

    Hepatocellular carcinoma (HCC) tends to develop in the liver when there is a high level of background inflammation (cirrhosis). Treatment options are limited and mainly based on systemic therapies such as anti-angiogenic drugs (e.g. sorafenib). Connective tissue growth factor (CTGF) is a matricellular protein involved in inflammation, tumour growth and angiogenesis. The aim of this study is to determine the expression of CTGF and hypoxia inducible factors (HIF) in HCC and to clarify its impact on relapse and survival. Eligibility criteria for the study consisted of patients with a diagnosis of HCC, formalin-fixed and paraffin-embedded (FFPE) biopsy tissue, as well as relapse and available survival data. A tissue microarray was constructed from ≥ 70% tumoural sections. The expressions of CTGF, HIF1α and HIF2α were analysed by immunohistochemistry. The relationship between expression of CTGF/HIF1α and CTGF/HIF2α were analysed. Univariate and multivariate analyses were performed. Fifty-three patients were screened; 39 patients were eligible for this study. Patients were treated with radical intent. At the end of follow up, 59% patients relapsed (28.2% locally, 10.3% multicentric liver relapse and 7.7% distant metastases). Estimated median disease-free survival (DFS) and overall survival (OS) were 23.4 (95%CI 7.18-39.66) and 38.6 months (95%CI 30.7-46.6), respectively. Expression of CTGF was: negative 23.1%, focal 48.7% and diffuse 23.1%. A non-statistically significant relationship between expression of CTGF and HIF was shown supporting an alternative pathway for CTGF expression in HCC. In multivariate analysis CTGF expression was an independent factor related to OS, with shorter survival in those patients with focal/diffuse CTGF expression (HR 2.46; 95%CI 1.18-5.15). Our results support that expression of CTGF is an independent factor associated with shorter OS in HCC. Further analysis of CTGF expression in a larger series of HCC patients is required to confirm

    To evaluate the contribution of the thermal dose parameters during regional hyperthermia (HT) treatment to the clinical outcomes in patients with cervical carcinoma (CC) who received chemoradiotherapy (CRT) plus HT. Data from a multicentre randomised clinical trial of concurrent CRT + HT vs. CRT alone were used to evaluate the efficacy and safety of this combination therapy in the CC patients. The intrarectal temperatures of patients undergoing HT were recorded. The complete thermal data of 47 (92%) of the 51 patients in the CRT + HT group were available for the thermal analysis. Thus, 47 patients who received CRT + HT were included in the present study. Among the patients who received CRT + HT, a higher CEM43T90 (≥1 min) value (a thermal dose parameter) was significantly associated with better local relapse-free survival in both univariate (p = 0.024) and multivariate (p = 0.0097) analyses. The disease-free survival of the patients with higher CEM43T90 (≥1 min) values tended to be better in comparison to patients with lower CEM43T90 (<1 min) value (p = 0.071). A complete response tended to be associated with the CEM43T90 (p = 0.056). Disease-free survival, local relapse-free survival and complete response rate for patients with higher CEM43T90 (≥1) were significantly better than those for patients with CRT alone (p = 0.036, p = 0.036 and p = 0.048). Dose-effect relationships between thermal dose parameters and clinical outcomes were confirmed in the CC patients treated with a combination of CRT + HT. This study also confirmed that HT with lower CEM43T90 is insufficient to achieve a significant hyperthermic sensitisation to CRT.

    Purpose: The aim of this study was to evaluate the effectiveness of low-dose-rate brachytherapy for local control and relapse-free survival in squamous cell and basal cell carcinomas of the lips. We compared two groups: one with tumors on the skin and the other with tumors on the lip. Patients and methods: All patients had been treated at Claudius Regaud Cancer Centre from 1990 to 2008 for squamous cell or basal cell carcinoma. Low-dose-rate brachytherapy was performed with iridium 192 wires according to the Paris system rules. On average, the dose delivered was 65 Gy. Results: 172 consecutive patients were included in our study; 69 had skin carcinoma (squamous cell or basal cell), and 92 had squamous cell mucosal carcinoma. The average follow-up time was 5.4 years. In the skin cancer group, there were five local recurrences and one lymph node recurrence. In the mucosal cancer group, there were ten local recurrences and five lymph node recurrences. The 8-year relapse-free survival for the entire population was 80%. The 8-year relapse-free survival was 85% for skin carcinoma 75% for mucosal carcinoma, with no significant difference between groups. The functional results were satisfactory for 99% of patients, and the cosmetic results were satisfactory for 92%. Maximal toxicity observed was Grade 2. Conclusions: Low-dose-rate brachytherapy can be used to treat lip carcinomas at Stages T1 and T2 as the only treatment with excellent results for local control and relapse-free survival. The benefits of brachytherapy are also cosmetic and functional, with 91% of patients having no side effects.

    Core-binding factor acute myeloid leukaemia (CBF AML) defined by t(8;21)(q22;q22) or inv(16)(p13q22)/t(16;16)(p13;q22) has a favourable prognosis, however 30-40% of patients still relapse after chemotherapy. We sought to evaluate risk factors for relapse in a de novo CBF AML cohort. A retrospective review of patients from 4 Australian tertiary centres from 2001-2012, comprising 40 t(8;21) and 30 inv(16) AMLs. Multivariate analysis identified age (p=0.032) and WCC>40 (p=0.025) as significant predictors for inferior OS and relapse respectively. Relapse risk was higher in the inv(16) group vs the t(8;21) group (57% vs 18%, HR 4.31, 95% CI: 1.78-10.42, p=0.001). Induction therapy had no bearing on OS or relapse free survival (RFS) however, consolidation treatment with >3 cycles of intermediate/high dose cytarabine improved OS (p=0.035) and relapse-free survival (RFS) (p=0.063). 5 patients demonstrated post-treatment stable q PCR positivity without relapse. (1)>3 consolidation cycles of intermediate/ high-dose cytarabine improves patient outcomes. (2)Age and inv(16) CBF AML subtype are predictors of inferior OS and RFS respectively. (3)Stable low-level MRD by qPCR does not predict relapse. (4)Similar OS in the inv(16) cohort compared to the t(8;21) cohort, despite a higher relapse rate, confirms salvageability of relapsed disease. This article is protected by copyright.

    Purpose: To evaluate long-term outcomes and toxicity in patients with unresectable paranasal sinus carcinoma treated with radiotherapy, with or without chemotherapy. Methods and Materials: Between January 1990 and December 2006, 39 patients with unresectable Stage IVB paranasal sinus carcinoma were treated definitively with chemotherapy plus radiotherapy (n = 35, 90%) or with radiotherapy alone (n = 4, 10%). Patients were treated with three-dimensional conformal radiotherapy (n = 18, 46%), intensity-modulated radiotherapy (n = 12, 31%), or conventional radiotherapy (n = 9, 23%) to a median treatment dose of 70 Gy. Most patients received concurrent platinum-based chemotherapy (n = 32, 82%) and/or concomitant boost radiotherapy (n = 29, 74%). Results: With a median follow-up of 90 months, the 5-year local progression-free survival, regional progression-free survival, distant metastasis-free survival, disease-free survival, and overall survival were 21%, 61%, 51%, 14%, and 15%, respectively. Patients primarily experienced local relapse (n = 25, 64%), mostly within the irradiated field (n = 22). Nine patients developed neck relapses; however none of the 4 patients receiving elective neck irradiation had a nodal relapse. In 13 patients acute Grade 3 mucositis developed. Severe late toxicities occurred in 2 patients with radionecrosis and 1 patient with unilateral blindness 7 years after intensity-modulated radiation therapy (77 Gy to the optic nerve). The only significant factor for improved local progression-free survival and overall survival was a biologically equivalent dose of radiation ≥65 Gy. Conclusions: Treatment outcomes for unresectable paranasal sinus carcinoma are poor, and combined-modality treatment is needed that is both more effective and associated with less morbidity. The addition of elective neck irradiation may improve regional control

    Effective treatments for patients with advanced locally recurrent nasopharyngeal carcinoma (NPC) are limited. This investigation was to determine the potential benefits from re-irradiation by intensity-modulated radiotherapy (IMRT) on survival and the effects of severe late toxicities. A retrospective study was conducted in 245 patients diagnosed with locally recurrent T3-T4 NPC who had undergone re-irradiation with IMRT. Follow-up data was colletedand factors associated with survival and severe late toxicities were analyzed. The 5-year local-regional failure-free survival, distant failure-free survival and overall survival rates were 60.9%, 78.3% and 27.5%, respectively. The presence of severe late complications, recurrent T4 disease and gross tumor volume >30 cm3 were associated with poor survival. The incidences of mucosal necrosis, temporal lobe necrosis, cranial neuropathy and trismus were 22.0%, 14.6%, 27.0% and 14.6% respectively. Re-irradiation with IMRT is an effective choice in patients with locally recurrent T3-T4 NPC. However, the survival benefits can be partly offset by severe late complications and optimum treatments in these patients remain a challenge.

    Purpose: To evaluate the response rate (RR) and time to local recurrence (TTLR) among patients who received salvage radiation therapy for relapsed or refractory aggressive non-Hodgkin lymphoma (NHL) and investigate whether RR and TTLR differed according to disease characteristics. Methods and Materials: A retrospective review was performed for all patients who completed a course of salvage radiation therapy between January 2001 and May 2011 at Brigham and Women's Hospital/Dana-Farber Cancer Institute. Separate analyses were conducted for patients treated with palliative and curative intent. Predictors of RR for each subgroup were assessed using a generalized estimating equation model. For patients treated with curative intent, local control (LC) and progression-free survival were estimated with the Kaplan-Meier method; predictors for TTLR were evaluated using a Cox proportional hazards regression model. Results: Salvage radiation therapy was used to treat 110 patients to 121 sites (76 curative, 45 palliative). Salvage radiation therapy was given as part of consolidation in 18% of patients treated with curative intent. Median dose was 37.8 Gy, with 58% and 36% of curative and palliative patients, respectively, receiving 39.6 Gy or higher. The RR was high (86% curative, 84% palliative). With a median follow-up of 4.8 years among living patients, 5-year LC and progression-free survival for curative patients were 66% and 34%, respectively. Refractory disease (hazard ratio 3.3; P=.024) and lack of response to initial chemotherapy (hazard ratio 4.3; P=.007) but not dose (P=.93) were associated with shorter TTLR. Despite doses of 39.6 Gy or higher, 2-year LC was only 61% for definitive patients with refractory disease or disease that did not respond to initial chemotherapy. Conclusions: Relapsed or refractory aggressive NHL is responsive to salvage radiation therapy, and durable LC can be achieved in some cases. However, refractory disease is associated with a

    Purpose: The purpose of this project is to develop a robust method of parameter estimation for a Poisson-based TCP model using Bayesian inference. Methods: Bayesian inference was performed using the PyMC3 probabilistic programming framework written in Python. A Poisson-based TCP regression model that accounts for clonogen proliferation was fit to observed rates of local relapse as a function of equivalent dose in 2 Gy fractions for a population of 623 stage-I non-small-cell lung cancer patients. The Slice Markov Chain Monte Carlo sampling algorithm was used to sample the posterior distributions, and was initiated using the maximum of the posterior distributions found by optimization. The calculation of TCP with each sample step required integration over the free parameter α, which was performed using an adaptive 24-point Gauss-Legendre quadrature. Convergence was verified via inspection of the trace plot and posterior distribution for each of the fit parameters, as well as with comparisons of the most probable parameter values with their respective maximum likelihood estimates. Results: Posterior distributions for α, the standard deviation of α (σ), the average tumour cell-doubling time (Td), and the repopulation delay time (Tk), were generated assuming α/β = 10 Gy, and a fixed clonogen density of 10{sup 7} cm−{sup 3}. Posterior predictive plots generated from samples from these posterior distributions are in excellent agreement with the observed rates of local relapse used in the Bayesian inference. The most probable values of the model parameters also agree well with maximum likelihood estimates. Conclusion: A robust method of performing Bayesian inference of TCP data using a complex TCP model has been established.

    Temsirolimus 175 mg once-weekly for 3 weeks, followed by 75 mg once-weekly intravenously dosed (175/75 mg) is approved in the European Union for treatment of relapsed/refractory mantle cell lymphoma (MCL). A phase IV study explored whether similar efficacy, but improved safety could be achieved with 75 mg without 175 mg loading doses (ClinicaTrials.gov: NCT01180049). Patients with relapsed/refractory MCL were randomized to once-weekly temsirolimus 175/75 mg (n = 47) or 75 mg (n = 42). Treatment continued until objective disease progression. Primary endpoint: progression-free survival (PFS). Secondary endpoints included overall survival (OS) and adverse events (AEs). Median PFS was 4.3 versus 4.5 months (hazard ratio [HR] 0.731; 80% confidence interval [CI], 0.520-1.027), and median OS 18.7 versus 11.0 months (HR 0.681; 80% CI, 0.472-0.982) with 175/75 mg versus 75 mg. There were fewer patients with serious AEs, dose reduction, or death with 175/75 mg (57.4%, 48.9%, and 48.9%) versus 75 mg (73.8%, 64.3%, and 65.1%). Temsirolimus 175/75 mg remains the preferred dosing regimen for relapsed/refractory MCL.

    Full Text Available To develop prognostic nomograms for predicting outcomes in patients with locally advanced rectal cancers who do not receive preoperative treatment.A total of 883 patients with stage II-III rectal cancers were retrospectively collected from a single institution. Survival analyses were performed to assess each variable for overall survival (OS, local recurrence (LR and distant metastases (DM. Cox models were performed to develop a predictive model for each endpoint. The performance of model prediction was validated by cross validation and on an independent group of patients.The 5-year LR, DM and OS rates were 22.3%, 32.7% and 63.8%, respectively. Two prognostic nomograms were successfully developed to predict 5-year OS and DM-free survival rates, with c-index of 0.70 (95% CI = [0.66, 0.73] and 0.68 (95% CI = [0.64, 0.72] on the original dataset, and 0.76 (95% CI = [0.67, 0.86] and 0.73 (95% CI = [0.63, 0.83] on the validation dataset, respectively. Factors in our models included age, gender, carcinoembryonic antigen value, tumor location, T stage, N stage, metastatic lymph nodes ratio, adjuvant chemotherapy and chemoradiotherapy. Predicted by our nomogram, substantial variability in terms of 5-year OS and DM-free survival was observed within each TNM stage category.The prognostic nomograms integrated demographic and clinicopathological factors to account for tumor and patient heterogeneity, and thereby provided a more individualized outcome prognostication. Our individualized prediction nomograms could help patients with preoperatively under-staged rectal cancer about their postoperative treatment strategies and follow-up protocols.

    Purpose: We had already established that familial prostate cancer, defined as prostate cancer diagnosed in a father or brother, was an independent predictor of biochemical failure after treatment for localized disease. Our aim was to determine whether differences in outcome could be observed with respect to clinical failures (either local or distant) between the two forms of prostate cancer. Methods: Of the 1685 consecutive cases with localized prostate carcinoma treated between 1986 and 1996, patients with the following were excluded from the present study: no pretreatment Prostatic Specific Antigen (iPSA) level (n=54), no biopsy Gleason score (bGS) (n=25), adjuvant or neoadjuvant treatment (n=234), no available follow-up PSA level (n=30). We also excluded 617 patients who did not have a minimum of 3 years potential follow-up. The analysis was performed on 725 cases. Radiotherapy (RT) was the primary treatment in 330 patients and radical prostatectomy (RP) in 395 patients. Five percent had clinical stage T3 disease (n=37). Positive family history was defined as the presence of prostate cancer in a first degree relative (father or brother). The outcomes of interest were biochemical relapse-free survival (bRFS), clinical relapse-free survival (cRFS), local relapse-free survival (locRFS), distant relapse-free survival (dRFS). We used proportional hazards to analyze the effect of family history and other potential confounding variables (i.e. age, race, treatment modality, stage, biopsy GS, and iPSA levels) on treatment outcome. We included pathologic findings (extracapsular extension, seminal vesicle involvement, surgical margin involvement, and lymph node metastases) in a separate analysis for RP patients. Results: The median follow-up was 45 months. Eight percent of all cases (n=57) had a positive family history. The 5-year bRFS rates for patients with negative and positive family history were 54% and 38%, respectively (p<0.001). The 5-year cRFS rates for patients

    Full Text Available Objective: Malignant tumors of minor salivary glands (MSG are rare. Survival outcome in Pakistani population with malignant MSG tumors remains to be defined. The objective of this study was to report the clinical presentation, treatment modalities, and survival outcome of radically treated malignant tumors of MSG in Pakistani population. Materials and Methods: Between April 2003 and March 2011, 45 patients with malignant tumors of MSG were treated at Shaukat Khanum Cancer Hospital and included in the study. Patient characteristics and treatment modalities were assessed and local, regional, and distant failures determined. Relapse-free (RFS and overall survival (OS was calculated using Kaplan-Meier curves, and log-rank test was used to determine significance. Results: Median age was 40 (17-83 years. Male to female ratio was 1.25:1. Most common site was hard palate in 31 (69% patients. Adenoid cystic carcinoma (51% was the most common histological diagnosis. Nine patients (20% underwent surgery as the only treatment modality, six patients received (13% radiotherapy alone, and 30 patients (67% had surgery followed by adjuvant radiotherapy. Eight patients developed recurrence (four local, two regional, one locoregional, and one distant. The 5-year actuarial overall OS and RFS was 77 and 66%, respectively. Age, T-stage, and treatment modality were significant for RFS, whereas T-stage and treatment modality were significant factors for OS. Conclusion: Surgery as single modality or combined with radiation therapy resulted in acceptable survival in Pakistani population with malignant minor salivary tumors.

    One-hundred and five patients undergoing allo-geneic bone marrow transplantation (BMT) for acute myeloid leukaemia (AML) (n=61) and chronic myeloid leukaemia (n=44) were analysed for risk factors associated with relapse. All patients received marrow from an HLA identical sibling after preparation with cyclophosphamide 120 mg/kg and total body irradiation (TBI) 330 cGy on each of the three days prior to transplantation. A multivariate Cox analysis indicated that a lower TBI dose (less than 990 cGy) was the most significant factor associated with relapse and the second most important factor associated with recurrence of leukaemia was the absence of chronic graft-versus-host-disease (cGvHD). Actuarial relapse incidence was 62%, 28% and 18% for patients with no, limited or extensive chronic GvHD respectively. However, chronic GvHD had no significant impact on survival. Combined stratification for TBI dose and cGvHD showed that the dose effect of TBI on relapse was evident both in patients with and without cGvHD. Chronic GvHD influenced the risk of relapse only in patients receiving less than 990 cGy. These results suggest that a higher dose of TBI, within this schedule, produced long-term disease-free survival in the majority of AMLs and CMLs. Minor radiobiological side effects were experienced, but a small reduction of the dose may significantly increase the risk of relapse. (author).

    The eye has traditionally been regarded as a sanctuary site for drugs, but recent publications have shown evidence of penetration by drugs and subsequent clinical response of intraocular lymphomas. In this report, a chemotherapy regimen, including high dose methotrexate and cytosine arabinoside, was used to re-induce remission in a patient with intraocular lymphoma relapsing locally after prior radiotherapy. She remains disease free 18 months later. (author).

    To assess the effects of adjuvant hormone therapy (AHT) on survival and disease outcome in women with epithelial ovarian cancer. Participants were premenopausal and postmenopausal women who had been diagnosed with epithelial ovarian cancer (any International Federation of Gynecology and Obstetrics stage) 9 or fewer months previously. Ineligible patients included those with deliberately preserved ovarian function, with a history of a hormone-dependent malignancy, or with any contraindications to hormone-replacement therapy. Patients were centrally randomly assigned in a 1:1 ratio to either AHT for 5 years after random assignment or no AHT (control). Main outcome measures were overall survival (OS), defined as time from random assignment to death (any cause), and relapse-free survival, defined as time from random assignment to relapse or death (any cause). Patients who continued, alive and relapse free, were censored at their last known follow-up. A total of 150 patients (n = 75, AHT; n = 75, control) were randomly assigned from 1990 to 1995 from 19 centers in the United Kingdom, Spain, and Hungary; all patients were included in intention-to-treat analyses. The median follow-up in alive patients is currently 19.1 years. Of the 75 patients with AHT, 53 (71%) have died compared with 68 (91%) of 75 patients in the control group. OS was significantly improved in patients who were receiving AHT (hazard ratio, 0.63; 95% CI, 0.44 to 0.90; P = .011). A similar effect was seen for relapse-free survival (hazard ratio, 0.67; 95% CI, 0.47 to 0.97; P = .032). Effects remained after adjustment for known prognostic factors. These results show that women who have severe menopausal symptoms after ovarian cancer treatment can safely take hormone-replacement therapy, and this may, in fact, infer benefits in terms of OS in addition to known advantages in terms of quality of life. © 2015 by American Society of Clinical Oncology.

    The optimal choice of salvage therapy for patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) or Hodgkin lymphoma (HL) remains unknown. Based on promising results of phase II trials, the preferred salvage regimen in British Columbia since 2002 has been the out-patient regimen, gemcitabine, dexamethasone, and cisplatin (GDP). We conducted a retrospective analysis including all patients with relapsed/refractory DLBCL or HL who received GDP as salvage therapy between September 2002 and June 2010. We identified 235 patients: 152 DLBCL, 83 HL. Overall response rates were 49% and 71% for patients with DLBCL and HL, respectively. Within the transplant-eligible population, 52% of patients with DLBCL and 96% of patients with HL proceeded to stem cell transplantation. The 2-year progression-free survival and overall survival were 21% and 28% in the DLBCL cohort, and 58% and 85% in the HL group. GDP is an effective and well-tolerated out-patient salvage regimen for relapsed/refractory DLBCL and HL.

    Purpose: To report the long-term outcome and patterns of relapse of a large cohort of marginal zone lymphoma (MZL) patients treated with curative-intent radiation therapy (RT) alone. Patients and Methods: We reviewed the charts of 490 consecutive patients with stage IE or IIE MZL referred between 1992 and 2012 to our institution. Of those, 244 patients (50%) were treated with RT alone. Pathology was confirmed by hematopathologists at our institution. Patient and disease factors were analyzed for association with relapse-free survival (RFS) and overall survival (OS). Results: Median age of the cohort was 59 years, and median follow-up was 5.2 years. Ann Arbor stage was IE in 92%. Most common disease sites were stomach (50%), orbit (18%), non-thyroid head-and-neck (8%), skin (8%), and breast (5%). Median RT dose was 30 Gy. Five-year OS and RFS were 92% and 74%, respectively. Cumulative incidence of disease-specific death was just 1.1% by 5 years. Sixty patients (24%) developed relapse of disease; 10 were in the RT field. Crude rate of transformation to pathologically confirmed large-cell lymphoma was 1.6%. On multivariable analysis, primary disease site (P=.007) was independently associated with RFS, along with age (P=.04), presence of B-symptoms (P=.02), and International Prognostic Index risk group (P=.03). All disease sites except for head-and-neck had worse RFS relative to stomach. Conclusion: Overall and cause-specific survival are high in early-stage extra-nodal MZL treated with curative RT alone. In this large cohort of 244 patients, most patients did not experience relapse of MZL after curative RT; when relapses did occur, the majority were in distant sites. Stomach cases were less likely to relapse than other anatomic sites. Transformation to large-cell lymphoma was rare

    Purpose The major causes of mortality after allogeneic hematopoietic-cell transplantation (allo-HCT) are relapse, graft-versus-host disease (GVHD), and infection. We have reported previously that alterations in the intestinal flora are associated with GVHD, bacteremia, and reduced overall survival after allo-HCT. Because intestinal bacteria are potent modulators of systemic immune responses, including antitumor effects, we hypothesized that components of the intestinal flora could be associated with relapse after allo-HCT. Methods The intestinal microbiota of 541 patients admitted for allo-HCT was profiled by means of 16S ribosomal sequencing of prospectively collected stool samples. We examined the relationship between abundance of microbiota species or groups of related species and relapse/progression of disease during 2 years of follow-up time after allo-HCT by using cause-specific proportional hazards in a retrospective discovery-validation cohort study. Results Higher abundance of a bacterial group composed mostly of Eubacterium limosum in the validation set was associated with a decreased risk of relapse/progression of disease (hazard ratio [HR], 0.82 per 10-fold increase in abundance; 95% CI, 0.71 to 0.95; P = .009). When the patients were categorized according to presence or absence of this bacterial group, presence also was associated with less relapse/progression of disease (HR, 0.52; 95% CI, 0.31 to 0.87; P = .01). The 2-year cumulative incidences of relapse/progression among patients with and without this group of bacteria were 19.8% and 33.8%, respectively. These associations remained significant in multivariable models and were strongest among recipients of T-cell-replete allografts. Conclusion We found associations between the abundance of a group of bacteria in the intestinal flora and relapse/progression of disease after allo-HCT. These might serve as potential biomarkers or therapeutic targets to prevent relapse and improve survival after allo-HCT.

    Purpose/Objective: To assess the five-year clinical and biochemical results of ultrasound-guided permanent I-125 brachytherapy in early prostate cancer. Biochemical disease-free survival (BDFS) is reported, using PSA follow-up and is compared to the surgical and radiation therapy literature. Materials and Methods: From 12/88 through 12/93, ultrasound-guided brachytherapy was preplanned with I-125 and delivered 16,000 cGy as the sole treatment in 499 patients. All were clinically staged as T1 or T2 - N0M0 adenocarcinoma of the prostate. Within the first year, 19 patients were lost to follow-up and have been excluded from further study. The remaining 480 patients form the basis of this report. Clinical status and PSA values were systematically recorded before and after treatment. Results: With a median follow-up of 35 months (3-70) the actuarial clinical local control is 83%. Both stage and grade are shown to predict for this endpoint. Actuarial BDFS is also correlated with stage, grade, and PSA at presentation. Biochemical disease-free survival at five years is 94% for T1, 70% for unilateral T2, and 34% for T2c tumors. Grade is also predictive, ranging from 85% in low-grade tumors to 30% in high-grade tumors. In a multivariate analysis, the pretreatment PSA is most highly correlated (p 10 had a BDFS of 40%. Complications have been few, with severe urinary urgency or dysuria in 4% and both incontinence and proctitis seen in 1%. Conclusion: While biochemical disease-free survival reports in the literature are immature and have short follow-up, our data compares favorably with studies following radical prostatectomy or radiation therapy. Further follow-up of this cohort is required. The complication rate is low and patient acceptance excellent. Permanent implantation of I-125 as the sole treatment for early prostate cancer is a viable alternative for patients with early stage and low- to moderate-grade cancers. The PSA provides significant prognostic information and

    Outcome of HIV-infected patients with AIDS-related lymphomas has improved during recent years. However, data on incidence, risk factors, and outcome of relapses in AIDS-related lymphomas after achieving complete remission are still limited. This prospective observational multicenter study includes HIV-infected patients with biopsy- or cytology-proven malignant lymphomas since 2005. Data on HIV infection and lymphoma characteristics, treatment and outcome were recorded. For this analysis, AIDS-related lymphomas patients in complete remission were analyzed in terms of their relapse- free survival and potential risk factors for relapses. In total, 254 of 399 (63.7%) patients with AIDS-related lymphomas reached a complete remission with their first-line chemotherapy. After a median follow up of 4.6 years, 5-year overall survival of the 254 patients was 87.8% (Standard Error 3.1%). Twenty-nine patients relapsed (11.4%). Several factors were independently associated with a higher relapse rate, including an unclassifiable histology, a stage III or IV according to the Ann Arbor Staging System, no concomitant combined antiretroviral therapy during chemotherapy and R-CHOP-based compared to more intensive chemotherapy regimens in Burkitt lymphomas. In conclusion, complete remission and relapse rates observed in our study are similar to those reported in HIV-negative non-Hodgkin lymphomas. These data provide further evidence for the use of concomitant combined antiretroviral therapy during chemotherapy and a benefit from more intensive chemotherapy regimens in Burkitt lymphomas. Modifications to the chemotherapy regimen appear to have only a limited impact on relapse rate. Copyright © 2018 Ferrata Storti Foundation.

    Purpose: Concomitant chemoradiotherapy (CRT) increases survival rates compared with radical radiotherapy alone (RT) in Stage III non-small-cell lung cancer (NSCLC), as a result of improved local control. The effect of CRT on local control in Stage I NSCLC is less well documented. We retrospectively reviewed local control and survival following CRT or RT for inoperable Stage I NSCLC patients. Methods and materials: Eligible patients had histologically/cytologically proved inoperable Stage I NSCLC and had undergone complete staging investigations including an F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) scan. Radiotherapy was planned as (1) 60 Gy in 30 fractions over 6 weeks with or without concomitant chemotherapy or (2) 50-55 Gy in 20 fractions without chemotherapy. Results: Between 2000 and 2005, 73 patients met the eligibility criteria and were treated as follows: CRT (60 Gy)-39; RT (60 Gy)-23; RT (50-55 Gy)-11. The median follow-up time for all patients was 18 months (range, 1-81 months). Survival analysis was based on intent to treat. Local progression-free survival (PFS) at 2 years was 66% with CRT and 55% with RT. The 2-year distant PFS was 60% following CRT and 63% after RT. The 2-year PFS rates were 57% and 50%, respectively. The 2-year survival rate for patients treated with CRT was 57% and 33% in patients receiving RT. Conclusions: Despite the use of CRT and routine staging with FDG-PET, both local and distant recurrences remain important causes of treatment failure in patients with inoperable stage I NSCLC.

    To report clinical outcomes of 125 I low-dose-rate prostate brachytherapy (LDR-PB) as monotherapy or combined with androgen-deprivation therapy (ADT) and/or external beam radiotherapy (EBRT) in high-risk localised prostate cancer. Analysis of clinical outcomes from a prospective cohort of patients treated with LDR-PB alone or combined treatment in a single institution. Men with a high risk of disease relapse were identified by the National Institute for Health and Care Excellence (NICE) criteria or by the National Comprehensive Cancer Network (NCCN) criteria. Relapse-free survival (RFS), overall survival (OS), prostate cancer-specific survival (PCSS), and metastases-free survival (MFS), were analysed together with patient-reported symptom scores and physician-reported adverse events. The NICE and NCCN criteria identified 267 and 202 high-risk patients, respectively. NICE-defined patients had significantly lower pre-treatment PSA levels, Gleason scores LDR-PB monotherapy. At 9 years after implantation RFS was 89% and 87% in the NICE and NCCN groups, respectively (log-rank P = 0.637), and OS 93% and 94%, respectively (log-rank P = 0.481). All of the survival estimates were similar between LDR-PB monotherapy and combined therapies. Cox proportional hazards regression confirmed RFS was similar between the treatment types. Treatment-related toxicity was also similar between the treatment methods. LDR-PB is effective at controlling localised prostate cancer in patients with a high risk of disease relapse. As the present study was not randomised, it is not possible to define those patients who need the addition of ADT and/or EBRT. However, the NICE criteria appear suitable to define treatment options where patients could benefit from LDR-PB as monotherapy or combined treatment. This choice should be discussed with the patient taking into account comorbidities and presence of multiple high-risk factors. © 2018 The Authors BJU International © 2018 BJU International

    GATA3 is a transcription factor regulating luminal cell differentiation in the mammary glands and has been implicated in the luminal types of breast carcinoma. The prognostic significance of GATA3 in breast cancer remains controversial. In this study, we assessed the prognostic value of the molecule in a subset of 62 advanced breast cancers and 10 control breast cancers (no metastasis after follow-up). GATA3 expression levels in luminal tumors of advanced stage were significantly higher than that of the human epidermal growth factor receptor 2 (HER2) subtype and triple-negative carcinomas, as expected, but were similar to those of the luminal controls. Furthermore, 88% of nonluminal tumors showed variable GATA3 expression, for which the HER2 subtype had significantly higher GATA3 expression than that of the triple-negative carcinomas. Interestingly, GATA3 levels were significantly lower in carcinomas with lung relapse compared to those with metastatic recurrence to other organs, thus reflecting the findings in animal models. No significant difference was observed between tumors with bone relapse and those metastasized to nonskeletal sites. Moreover, high GATA3 expression was significantly associated with favorable relapse-free survival and overall survival. These findings suggest that GATA3 may not act solely as a luminal differentiation marker, and further uncovering the molecular pathways by which GATA3 regulates the downstream targets will be crucial to our understanding of breast cancer dissemination.

    Purpose: To assess the role of intracavitary mold brachytherapy in salvaging local failure of nasopharyngeal carcinoma (NPC). Methods and Materials: The outcomes of 118 consecutive NPC patients with local failure treated with mold brachytherapy between 1989 and 1996 were retrospectively reviewed. Eleven patients received additional external radiotherapy. Results: All molds were tailor-made, and the whole procedure was performed under local anesthesia. Pharyngeal recess dissection was routinely performed to allow direct contact of the radioactive source with the pharyngeal recess, a common site of local failure. Initially, the molds were preloaded with 192 Ir wires, but since 1992, the sources have been manually afterloaded; the mold has also been redesigned for better conformity, ease of insertion, and radiation safety. Using brachytherapy alone, 50-55 Gy was given for recurrence in 4-7 days; for persistence, 40 Gy was administered. The overall complete remission rate was 97%. The rates of 5-year local control, relapse-free survival, disease-specific survival, overall survival, and major complication were 85%, 68.3%, 74.8%, 61.3%, and 46.9%, respectively. Major complications included nasopharyngeal necrosis with headache, necrosis of cervical vertebrae with atlantoaxial instability, temporal lobe necrosis, and palsy of the cranial nerves. The afterloaded mold was as effective as the preloaded version, but with fewer complications. Conclusions: Intracavitary mold brachytherapy was effective in salvaging NPC with early-stage local persistence or first recurrence

    The objective of this study was to evaluate retrospectively the clinical characteristics, treatments, and outcomes of patients with primary diffuse large B-cell lymphoma (DLBCL) of the female genital tract. The basic characteristics, treatments, and outcomes of six patients diagnosed with primary DLBCL of the female genital tract, including the ovary, uterine cervix, and vagina, treated in our hospital between 2000 and 2012, were analyzed retrospectively. Seven of 323 (2.2 %) newly diagnosed DLBCLs were diagnosed as primary female genital tract DLBCL. Six patients with complete medical data were included in the analysis. The median age at diagnosis was 52.5 years (range 20-65). The presenting symptoms included abnormal vaginal bleeding, increased vaginal discharge, abdominal fullness, and abdominal pain. Two patients had stage IE disease and four patients had stage IIE disease. Treatment included chemotherapy only in five patients, and combined chemotherapy and localized radiation in one patient. After a median follow-up of 58 months, four patients showed relapse in the central nervous system and two had died from progressive disease. The median progression-free survival was 27 months and the median overall survival for this group has not been reached. Patients with primary female genital tract DLBCL may have poor outcomes and a high risk of central nervous system relapse. Central nervous system prophylaxis might be considered in addition to systemic chemotherapy for DLBCL of the female genital tract.

    Purpose: The aim of this study was to evaluate the toxicity, response, and survival of patients with relapsed high-grade gliomas after radiation therapy (RT) combined with lomustine (CCNU). Methods and Materials: Thirty-one patients with relapsed gliomas at least 6 months after completion of RT were reirradiated. Twenty-four patients had a pathological diagnosis of high-grade gliomas, whereas 7 had a radiological diagnosis of relapsed malignant gliomas. The study focused on patients with high-grade relapsed gliomas. A total dose of 34.5 Gy was delivered in 23 fractions over 4.5 weeks. Oral administration of CCNU (130 mg/m 2 ) was begun at the same time as RT, and was repeated every 6 weeks until disease progression, or up to 12 courses. Results: Twelve of 24 patients had surgery before RT plus CCNU treatment. Median interval between RT courses was 14 months (range 6-73). All patients received a complete course of RT, and 22 of 24 patients received at least one course of CCNU. Objective responses were seen in 14 evaluable patients: 3 with partial response, 5 with stable disease, and 6 with progressive disease. Duration of partial response was 20, 9, and 8 months. Median time to progression and overall survival from the onset of retreatment were 8.4 months (range 1-22) and 13.7 months (range 1-63+), respectively. One case of G4 thrombocytopenia was observed. Five patients had G1 or G2 leucopenia and 3 patients had G3 leucopenia. Moderate nausea and vomiting were reported in 4 patients. One patient, after one course of CCNU, refused further chemotherapy. No significant difference in survival from relapse was found between patients who underwent surgery before RT plus CCNU and those who received only RT plus CCNU (p = 0.74). Conclusion: Overall, the acute toxicity was moderate, and patient compliance was good. Reirradiation of high-grade glioma was associated with modest subjective and objective response rates. It is remarkable that median overall survival from relapse

    Purpose: To report the 5-year prostate-specific antigen (PSA) relapse-free survival outcome and incidence of long-term morbidity for patients with localized prostate cancer treated with CT-planned permanent I-125 prostate implantation using a transperineal technique (TPI). Methods and Materials: Between 1989-1996, 248 patients with clinically localized prostate cancer were treated with TPI. The median age was 65 years (range: 45-80 years). The clinical stage was T1c in 143 patients (58%), Stage T2a in 102 (41%), and T2b in 3 (1%). Thirty patients (12%) had Gleason scores 10 ng/mL and Gleason score >6) were classified as having intermediate and unfavorable risk disease, respectively. PSA relapse was defined according to the American Society of Therapeutic Radiation Oncology Consensus Statement, and toxicity was scored according to the Radiation Therapy Oncology Group morbidity scoring scale. The median follow-up was 48 months (range: 12-126 months). Results: Thirty-eight patients (15%) developed a PSA relapse, and the overall 5-year PSA relapse-free survival (PRFS) rate was 71%. The 5-year PRFS rates for favorable-risk (n = 146), intermediate-risk (n = 85), and unfavorable-risk (n = 17) patients were 88%, 77%, and 38%, respectively (p 10 ng/mL and Gleason score >6 as independent predictors for biochemical relapse after TPI. The 5-year actuarial likelihood of late Grade 2 urinary toxicity was 41%. The 5-year likelihood of urethral stricture development was 10%, and the median time to stricture development was 18 months. One patient (0.4%) in the early phase of this clinical experience developed a Grade 4 urethral complication. The actuarial incidence of late Grade 2 rectal bleeding was 9%. One patient (0.4%) developed a Grade 4 rectal complication. Conclusions: Especially for favorable risk disease, the 5-year biochemical outcome with this approach was excellent and appears to be comparable to other therapeutic interventions. Grade 2 urinary symptoms were common in

    Purpose: To retrospectively review the outcome of conservatively treated breast cancer patients who present with nipple discharge at initial diagnosis. Methods and Materials: The charts of 1097 patients undergoing conservative surgery and radiation therapy between January 1970 and December 1990 were reviewed. All patient data, including clinical, pathologic, treatment, and outcome variables were entered onto a computerized database. For the current study, specific attention was directed to the initial presenting symptoms and patients were divided into two groups: those presenting at initial diagnosis with nipple discharge (D/C-YES, n = 17), and those presenting without nipple discharge (D/C-NO, n = 1080). Results: As of August 1998, with a median follow-up of 12 years, the 10-year actuarial survival, distant metastasis-free survival, and breast relapse-free survival rates for the overall population were 73%, 78%, and 83%, respectively. Although the D/C-YES and D/C-NO groups were well balanced with respect to the majority of clinical factors, the D/C-YES patients had a higher percentage of DCIS histology (7.3% vs 1.2%, p < 0.01), were less likely to undergo reexcision (12% vs 35%), and were more frequently under age 40 (35% vs 12%) than the D/C-NO patients. Over the time span of this study, status of the final surgical margin was indeterminate in the majority of cases. Local relapses occurred in 6 of the 17 patients in the D/C-YES group, resulting in a 10-year actuarial breast relapse-free survival rate of 50%, which was significantly lower than the 10-year breast relapse-free survival rate of 86% in the D/C-NO population. Among the patients presenting with nipple discharge, those with sacrifice of the nipple areolar complex had a lower local relapse rate than those patients who had conservation of the nipple areolar complex (20% vs 42%), although this difference did not reach statistical significance. Conclusions: Although patients presenting with nipple discharge

    The records of all patients treated for thymoma in the Department of Radiotherapy of Torino University between 1970 and 1988 were reviewed. There were 59 in stage 3 and 18 in stage 4a; 74 patients were operated before radiotherapy and 3 had a pre-operative irradiation followed by surgery and post-operative boost. Complete resection was possible in 55.9 per cent of stage 3 cases and in none with stage 4a. Subtotal resection was done in 36.6 per cent of stage 3 patients and 83.3 per cent in stage 4a. 8 patients had only biopsy: 5 in stage 3 (8.5 per cent) and 3 in stage 4a (16.6 per cent). Post-operative radiation doses ranged between 39.6 and 46 Gy to the whole mediastinum followed by a 10-16 Gy boost on smaller fields in cases presenting residual disease after surgery. The pre-operative dose was 30 Gy followed by a post-operative boost of 16-24 Gy. Conventional fraction sizes of 1.8-2 Gy were always used. The 10 years survival rate was 58.3 per cent. There was a significant difference between stage 3 (70.9 per cent) and stage 4a (26.3 per cent)(p<0.0004). Survival of patients in stage 3 was not significantly affected by the type of surgery. No significant difference in survival or recurrence rate was observed in patients with different histologies and in patients with or without myasthenia. Thoracic relapses occurred in 15. 2 per cent of stage 3 patients and in 50 per cent of stage 4a patients (p<0.01). Only 7 relapses (9.1 per cent) were within the limits of the radiation field. Radiotherapy seems to be effective in reducing the risk of local recurrence and prolonging survival in patients operated upon for locally advanced thymoma. More patients are alive and free of disease at 10 years than those who received radical surgery. (author). 26 refs.; 4 figs.; 5 tabs

    Purpose: We report the long-term results of integrated accelerated involved field radiation therapy (IFRT) followed by total lymphoid irradiation (TLI) as part of the high-dose salvage regimen followed by autologous bone marrow transplantation or autologous stem cell transplantation in patients with relapsed or refractory Hodgkin lymphoma (HL). Methods and Materials: From November 1985 to July 2008, 186 previously unirradiated patients with relapsed or refractory HL underwent salvage therapy on 4 consecutive institutional review board–approved protocols. All patients had biopsy-proven primary refractory or relapsed HL. After standard-dose salvage chemotherapy (SC), accelerated IFRT (18-20 Gy) was given to relapsed or refractory sites, followed by TLI (15-18 Gy) and high-dose chemotherapy. Overall survival (OS) and event-free survival (EFS) were analyzed by Cox analysis and disease-specific survival (DSS) by competing-risk regression. Results: With a median follow-up period of 57 months among survivors, 5- and 10-year OS rates were 68% and 56%, respectively; 5- and 10-year EFS rates were 62% and 56%, respectively; and 5- and 10-year cumulative incidences of HL-related deaths were 21% and 29%, respectively. On multivariate analysis, complete response to SC was independently associated with improved OS and EFS. Primary refractory disease and extranodal disease were independently associated with poor DSS. Eight patients had grade 3 or higher cardiac toxicity, with 3 deaths. Second malignancies developed in 10 patients, 5 of whom died. Conclusions: Accelerated IFRT followed by TLI and high-dose chemotherapy is an effective, feasible, and safe salvage strategy for patients with relapsed or refractory HL with excellent long-term OS, EFS, and DSS. Complete response to SC is the most important prognostic factor.

    The prognostic relevance of preoperative high-resolution magnetic resonance imaging (MRI) assessment of circumferential resection margin (CRM) involvement is unknown. This follow-up study of 374 patients with rectal cancer reports the relationship between preoperative MRI assessment of CRM staging, American Joint Committee on Cancer (AJCC) TNM stage, and clinical variables with overall survival (OS), disease-free survival (DFS), and time to local recurrence (LR). Patients underwent protocol high-resolution pelvic MRI. Tumor distance to the mesorectal fascia of ≤ 1 mm was recorded as an MRI-involved CRM. A Cox proportional hazards model was used in multivariate analysis to determine the relationship of MRI assessment of CRM to survivorship after adjusting for preoperative covariates. Surviving patients were followed for a median of 62 months. The 5-year OS was 62.2% in patients with MRI-clear CRM compared with 42.2% in patients with MRI-involved CRM with a hazard ratio (HR) of 1.97 (95% CI, 1.27 to 3.04; P < .01). The 5-year DFS was 67.2% (95% CI, 61.4% to 73%) for MRI-clear CRM compared with 47.3% (95% CI, 33.7% to 60.9%) for MRI-involved CRM with an HR of 1.65 (95% CI, 1.01 to 2.69; P < .05). Local recurrence HR for MRI-involved CRM was 3.50 (95% CI, 1.53 to 8.00; P < .05). MRI-involved CRM was the only preoperative staging parameter that remained significant for OS, DFS, and LR on multivariate analysis. High-resolution MRI preoperative assessment of CRM status is superior to AJCC TNM-based criteria for assessing risk of LR, DFS, and OS. Furthermore, MRI CRM involvement is significantly associated with distant metastatic disease; therefore, colorectal cancer teams could intensify treatment and follow-up accordingly to improve survival outcomes.

  5. Scintigraphic diagnosis and computed tomographic localization of an accessory spleen following relapse of chronic immune thrombocytopaenia

    Chronic immune thrombocytopaenia is an immunologically mediated disorder resulting in disordered platelet kinetics and potentially life-threatening disease. Failure of medical therapy is an indication for splenectomy, and responses are seen in 80% of patients following this procedure. An important cause of relapse following splenectomy is the presence of an accessory spleen. A patient with Hodgkin's Disease developed chronic immune thrombocytopaenia despite previous splenectomy. A remission was induced with immunosuppressive therapy, but he later relapsed. An accessory spleen was detected using 99 m Tc denatured red blood cells and localized using computed tomography. Resection of the accessory spleen resulted in clinical remission. As accessory spleens are often small in size, combined modality imaging is recommended in the evaluation of this disorder. 15 refs., 2 figs

    A previous US study reported poorer survival in children with acute lymphoblastic leukemia (ALL) exposed to extremely low-frequency magnetic fields (ELF-MF) above 0.3 μT, but based on small numbers. Data from 3073 cases of childhood ALL were pooled from prospective studies conducted in Canada......, Denmark, Germany, Japan, UK and US to determine death or relapse up to 10 years from diagnosis. Adjusting for known prognostic factors, we calculated hazard ratios (HRs) and 95% confidence intervals (CI) for overall survival and event-free survival for ELF-MF exposure categories and by 0.1 μT increases...

  7. Lapse and relapse following inpatient treatment of opiate dependence.

    2010-06-01

    We conducted a prospective follow-up study of consecutive opiate dependent patients admitted to a residential addiction treatment service for detoxification. We measured the rate of relapse following discharge, and sought to identify factors that were associated with early relapse (i.e., a return to daily opiate use). Follow-up interviews were conducted with 109 patients, of whom, 99 (91%) reported a relapse. The initial relapse occurred within one week in 64 (59%) cases. Multivariate survival analysis revealed that earlier relapse was significantly predicted by younger age, greater heroin use prior to treatment, history of injecting, and a failure to enter aftercare. Unexpectedly, those who were in a relationship with an opiate user had significantly delayed relapse. Those who completed the entire six-week inpatient treatment programme also had a significantly delayed relapse. In order to reduce relapse and the associated increased risk of fatal overdose, services providing residential opiate detoxification should prepare people for admission, strive to retain them in treatment for the full admission period and actively support their entry into planned aftercare in order to improve outcome.

    2009-01-01

    Nearly half of breast cancer patients in developing countries present with a locally advanced cancer. Treatment is centered on a multimodal approach based on chemotherapy, surgery and radiotherapy. The growing use of neoadjuvant chemotherapy has led to a more conservative surgical approach; nonetheless, it is not yet considered as a standard. There are no clear recommendations on the use of a radiotherapy boost in such situation. A Medline search was developed. Most articles are retrospective series. Survival free of locoregional relapse in patients treated with neoadjuvant chemotherapy, breast conserving surgery and radiotherapy is good. All articles described a boost administered to nearly all patients without regard to their prognostic factors, given that a locally advanced tumor is already considered as a poor prognostic factor. Even tough the poor level of evidence, a recommendation can be made: radiotherapy boost should be administered to all patients with locally advanced breast cancer treated with neoadjuvant chemotherapy and breast conserving surgery.

    Full Text Available Neuroblastoma (NB is the most common cancer in infancy and most frequent cause of death from extracranial solid tumors in children. Ornithine decarboxylase (ODC expression is an independent indicator of poor prognosis in NB patients. This study investigated safety, response, pharmacokinetics, genetic and metabolic factors associated with ODC in a clinical trial of the ODC inhibitor difluoromethylornithine (DFMO ± etoposide for patients with relapsed or refractory NB.Twenty-one patients participated in a phase I study of daily oral DFMO alone for three weeks, followed by additional three-week cycles of DFMO plus daily oral etoposide. No dose limiting toxicities (DLTs were identified in patients taking doses of DFMO between 500-1500 mg/m2 orally twice a day. DFMO pharmacokinetics, single nucleotide polymorphisms (SNPs in the ODC gene and urinary levels of substrates for the tissue polyamine exporter were measured. Urinary polyamine levels varied among patients at baseline. Patients with the minor T-allele at rs2302616 of the ODC gene had higher baseline levels (p=0.02 of, and larger decreases in, total urinary polyamines during the first cycle of DFMO therapy (p=0.003 and had median progression free survival (PFS that was over three times longer, compared to patients with the major G allele at this locus although this last result was not statistically significant (p=0.07. Six of 18 evaluable patients were progression free during the trial period with three patients continuing progression free at 663, 1559 and 1573 days after initiating treatment. Median progression-free survival was less among patients having increased urinary polyamines, especially diacetylspermine, although this result was not statistically significant (p=0.056.DFMO doses of 500-1500 mg/m2/day are safe and well tolerated in children with relapsed NB.

    The literature on metastasis-directed therapy for oligometastatic prostate cancer (PCa) recurrence consists of small heterogeneous studies. This study aimed to reduce the heterogeneity by pooling individual patient data from different institutions treating oligometastatic PCa recurrence with stereotactic body radiotherapy (SBRT). We focussed on patients who were treatment naive, with the aim of determining if SBRT could delay disease progression. We included patients with three or fewer metastases. The Kaplan-Meier method was used to estimate distant progression-free survival (DPFS) and local progression-free survival (LPFS). Toxicity was scored using the Common Terminology Criteria for Adverse Events. In total, 163 metastases were treated in 119 patients. The median DPFS was 21 mo (95% confidence interval, 15-26 mo). A lower radiotherapy dose predicted a higher local recurrence rate with a 3-yr LPFS of 79% for patients treated with a biologically effective dose ≤100Gy versus 99% for patients treated with >100Gy (p=0.01). Seventeen patients (14%) developed toxicity classified as grade 1, and three patients (3%) developed grade 2 toxicity. No grade ≥3 toxicity occurred. These results should serve as a benchmark for future prospective trials. This multi-institutional study pools all of the available data on the use of stereotactic body radiotherapy for limited prostate cancer metastases. We concluded that this approach is safe and associated with a prolonged treatment progression-free survival. Copyright © 2015. Published by Elsevier B.V.

    The purpose of this study is to investigate the effective of alternating Chemo-radiotherapy for locally Advanced Nasopharyngeal Carcinoma. Retrospective analysis 106 cases of patients with locally advanced nasopharyngeal carcinoma between November 2005 and March 2007. All patients received cisplatin-based chemotherapy but 15 patients received radiotherapy(RT) alone. Inducing chemotherapy (IC) + RT + adju-vant chemotherapy (AC) regimen in 36 patients, IC+RT regimen was delivered in 25 patients and AC + RT regimen in 30 patients. 61 patients received 1 to 2 cycles of inducing chemotherapy and 66 patients received 3 to 6 cycles of adjuvant chemotherapy after radiotherapy. Chemotherapy started on the first day after the end of the induction chemotherapy, adjuvant chemotherapy begun after radiotherapy for a week. All patients were treated by radiotherapy using 60 Co r-ray, the nasophyarynx primary site was given a total does of 68 -74 Gy. The lymph nodes of the neck was given 60 to 70 Gy. The prophylactic irradiation does of the neck was 48-50 Gy. RESCULT: The median follow up time was 51 months. A total of 58 patients died, the overall survival rate was 45% in whole groups. The 5-year overall survival rates were 33%, 63%, 60% and 50% in RT, IC + RT + AC, IC + RT and RT+AC group, respectively. The 5-year disease-free survival rates were 13%, 56%, 48% and 40% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year relapse-free survival rates were 13%, 53%, 48% and 50% in RT, IC + RT + AC, IC + RT and RT + AC group, respectively. The 5-year metastasis-free survival rates were 6%, 50%, 44% and 47% in RT, IC + RT + AC, IC+ RT and RT + AC group, respectively. There was significant difference in all groups (P 0.05). IC + RT + AC group had heavier acute toxicity effects than other groups, but it did not affect the treatment process, all patients could be tolerated.

So far, no predictive or prognostic molecular factors for patients undergoing multimodal treatment are established. Increased angiogenesis and altered tumour metabolism as adaption to hypoxic conditions in cancers play an important role in tumour progression and metastasis. Enhanced expression of Vascular-endothelial-growth-factor-receptor (VEGF-R and Transketolase-like-1 (TKTL1 are related to hypoxic conditions in tumours. In search for potential prognostic molecular markers we investigated the expression of VEGFR-1, VEGFR-2 and TKTL1 in patients with LARC treated with neoadjuvant chemoradiotherapy and cetuximab. Methods Tumour and corresponding normal tissue from pre-therapeutic biopsies of 33 patients (m: 23, f: 10; median age: 61 years with LARC treated in phase-I and II trials with neoadjuvant chemoradiotherapy (cetuximab, irinotecan, capecitabine in combination with radiotherapy were analysed by quantitative PCR. Results Significantly higher expression of VEGFR-1/2 was found in tumour tissue in pre-treatment biopsies as well as in resected specimen after neoadjuvant chemoradiotherapy compared to corresponding normal tissue. High TKTL1 expression significantly correlated with disease free survival. None of the markers had influence on early response parameters such as tumour regression grading. There was no correlation of gene expression between the investigated markers. Conclusion High TKTL-1 expression correlates with poor prognosis in terms of 3 year disease-free survival in patients with LARC treated with intensified neoadjuvant chemoradiotherapy and may therefore serve as a molecular prognostic marker which should be further evaluated in randomised clinical trials.

    A second SCT is generally accepted as the only potentially curative approach for ALL patients that relapse after SCT, but the role of second SCT for pediatric ALL is not fully understood. We performed a retrospective analysis of 171 pediatric patients who received a second allo-SCT for relapsed ALL after allo-SCT. OS at 2 years was 29.4 ± 3.7%, the cumulative incidence of relapse was 44.1 ± 4.0% and non-relapse mortality was 18.8 ± 3.5%. Relapse occurred faster after the second SCT than after the first SCT (117 days vs 164 days, P=0.04). Younger age (9 years or less), late relapse (180 days or more after first SCT), CR at the second SCT, and myeloablative conditioning were found to be related to longer survival. Neither acute GVHD nor the type of donor influenced the outcome of second SCT. Multivariate analysis showed that younger age and late relapse were associated with better outcomes. Our analysis suggests that second SCT for relapsed pediatric ALL is an appropriate treatment option for patients that have achieved CR, which is associated with late relapse after the first SCT.

    Objective: To assess the outcome and determine prognostic factors for patients treated with external beam radiotherapy following radical prostatectomy. Methods and Materials: Forty-four patients were treated after prostatectomy with radiotherapy between March 1988 and October 1993. All patients were free from clinically or radiographically suspicious local or distant disease. One patient underwent neoadjuvant hormonal therapy, but no other patients received hormonal therapy prior to radiation. Pre-radiotherapy PSA and follow-up PSA data were available in all patients. Four patients had undetectable PSA ( 7, and 11% had nodal involvement. Survival was analyzed using the life table method. Actuarial freedom from biochemical (BCM) failure, defined as a rise of greater than 10% or an undetectable PSA becoming detectable, was the primary endpoint studied. Results: Fifty-nine percent of patients had a detectable PSA return to undetectable levels after XRT. The actuarial five year freedom from biochemical failure for all patients was 24%. A significant difference in BCM disease free survival was seen for patients irradiated with a pre-XRT PSA ≤2.7 versus a pre-XRT PSA >2.7 (p=0.0001). Sixty percent of the former group were BCM disease free versus 0% in the latter. Biochemical disease free survival was not affected by preoperative PSA level, presence of undetectable PSA after surgery, surgery to radiation interval, seminal vesicle invasion, clinical stage, pathologic stage, Gleasons grade, or total dose. There were no symptomatic or clinically suspicious local failures, and there were no grade 3, 4, or 5 acute or late complications. There were 69% grade 1 and 2 acute reactions and one grade 2 late complication. Conclusions: Pelvic radiotherapy for patients with a PSA of ≤2.7 after prostatectomy was effective in biochemically controlling 60% of the patients with four years median follow up. To our knowledge these data represent the longest follow-up for this patient

    Full Text Available Elisabeth QuoixService de Pneumologie, Hôpitaux Universitaires, Strasbourg, FranceAbstract: Small cell lung cancer (SCLC represents about 15% to 20% of all lung cancers. Chemotherapy is the cornerstone of the treatment, cisplatin–etoposide combination being the most used combination as first-line therapy. Despite high initial chemosensitivity, most SCLC patients will experience relapse sooner or later. Unfortunately, second-line chemotherapy does not result in a high response rate like first-line therapy, most patients having developed wide chemoresistance. This chemoresistance is far more important in refractory patients, ie, those who never responded to first-line therapy or who relapsed within 3 months after the end of chemotherapy, than in sensitive patients, ie, those who relapse more than 3 months after the end of chemotherapy. Topotecan, a topoisomerase I inhibitor, is the most studied drug in this second-line setting and has proved its efficacy as a single agent and in combination. A phase III trial comparing oral topotecan to best supportive care (BSC in relapsed SCLC demonstrated a significant survival benefit as well as a better quality of life. Although the usual schedule is 1.5 mg/m2, days 1–5 intravenously, it is not convenient for patients with relapsed SCLC, especially those who are refractory because of their short survival expectation. Oral topotecan is of similar efficacy and much more convenient with limited stay in a treatment unit and has a comparable toxicity profile for these patients with short expected survival. Combination of topotecan with platinum salts or taxanes does not seem to improve further the outcome of the patients and thus single-agent therapy with topotecan is the standard treatment for relapsed SCLC.Keywords: topotecan, small cell lung cancer, chemoresistance

    The evaluation of 5-year results obtained through 2 radiochemotherapy (RCT) regimens: cisplatin (CDDP), 20 mg/m × 5 days every 21 days; and CDDP, 40 mg/m per week in locally advanced cervical carcinoma. In this single-institution prospective randomized phase 3 study, 326 patients with stage IIB to IIIB squamous cell cervical carcinoma treated from March 2003 to March 2005 were included. One hundred sixty patients (49%) had stage IIB cervical carcinoma, 103 patients (31.5%) had stage IIIA cervical carcinoma, and 63 patients (19.5%) had stage IIIB cervical carcinoma. The patients were randomly assigned to 2 therapeutic arms: 164 patients in arm A (5 days) concurrent RCT with CDDP, 20 mg/m per day, days 1 to 5 every 21 days; and 162 patients in arm B (weekly), concurrent RCT with CDDP, 40 mg/m per day weekly. All patients were treated with external beam radiotherapy on the abdominopelvic region using 15-MV x-rays and a cervical boost using the x-rays arch technique or medium-dose-rate intracavitary brachytherapy. The 5-year survival rate obtained through the 2 RCT regimens are not statistically different, even if a tendency of superiority can be observed in the 5-day arm as far as overall survival (78% in arm A vs 72% in arm B; p = 0.14) and disease-free survival (73% in arm A and 69% in arm B; p = 0.09) are concerned. Five-year local relapse-free survival was significantly superior in the 5-day CDDP arm (87%) in comparison with the weekly CDDP arm (77%); p < 0.01. In the 5-day arm, local relapse rate was twice lower, 21/164 (13%), compared with the weekly arm, 40/162 (25%); p < 0.01). Distance failures were identical in the 2 therapeutic groups: 22/164 (13%) and 21/162 (13%), respectively, which shows the superiority of arm A regarding local control. The results of our study demonstrate that RCT with cisplatin, 20 mg/m × 5 days every 21 days, is superior regarding local efficacy and is less toxic compared with the weekly chemotherapy regimen.

    There is no standard salvage chemotherapy for relapsed or refractory peripheral T-cell lymphomas (PTCLs). Gemcitabine combined with cisplatin has been known as an effective regimen for lymphoma treatment in the salvage setting. We investigated the efficacy and toxicity of gemcitabine, dexamethasone, and cisplatin (GDP) for relapsed or refractory PTCLs in search of a more effective and less toxic therapy. Patients with relapsed or refractory PTCLs with more than one previous regimen were eligible. Treatment consisted of gemcitabine 1000 mg/m(2) intravenously (i.v.) on days 1 and 8, dexamethasone 40 mg orally on days 1-4, and cisplatin 70 mg/m(2) i.v. on day 1, and then every 21 days. Patients could proceed to autologous stem cell transplantation (ASCT) after four cycles of GDP or receive up to six treatment cycles. Twenty-five eligible patients were evaluated for toxicity and response. The diagnoses of participants included 14 cases of PTCL-not otherwise specified (NOS) (56 %) and four cases of angioimmunoblastic T-cell lymphoma (16 %) among others. The median age of the patients was 59 years (range 20-75 years). After treatments with GDP, which delivered a median of four GDP cycles, there were 12 patients with complete responses (CR; 48 %) and six with partial responses (PR; 24 %). The overall response rate (RR) was 72 %. Four patients preceded to ASCT, and three patients finally achieved CR. The median progression free survival was 9.3 months (95 % confidence interval (CI); 4.1-14.6) with a median follow-up duration of 27.1 months. In a total of 86 cycles of GDP, grade 3 or 4 neutropenia and thrombocytopenia occurred in 16.3 and 12.8 % of cycles, respectively. Three patients (3.3 %) experienced febrile neutropenia. GDP is a highly effective and optimal salvage regimen for relapsed or refractory PTCLs and can be administered with acceptable toxicity.

    Between 1974 and 1977, 85 patients with breast cancer at first postmastectomy relapse were irradiated (Radiation 3500 to 6000 rad--3/5 weeks) to all clinically evident lesions. Radiation fields were properly shaped to include a maximum 40% active bone marrow. After 3 to 4 weeks rest, chemotherapy was started as adjuvant therapy for residual or subclinical disease (ADR 30 mg/M 2 Day 1 and 8, 5-FU 400 mg/M 2 Day 1 and 8, CY 100 mg/M 2 Day 1 through 14: repeated after 14 days). ADR was discontinued at 500/M 2 and substituted by MTX 30 mg/M 2 Day 1 and 8 for a total of 2 years. Irradiated sites were chest wall in 35, supraclavicular and internal mammary nodes in 22, bone in 56, single lung lesions in 12, brain in 24. Controls were 52 comparable but non-randomized patients treated with chemotherapy only. Forty days after x-irradiation 68 patients (80%) were free of disease (NED) while in 17 cases (20%) some residual was still present (RED). In 28 of 68 cases (41%) NED after x-irradiation and 13 of 17 (76%) in RED group developed second relapse after a median interval of 26 and 20 mos., respectively. Four of 52 patients (8%) in the control group had complete regression with a median interval to second relapse of 7 mos. Median survival was 30 mos., 24 mos., and 13 mos., respectively, for NED, RED and chemotherapy only. Eighteen patients (26%) are free of disease after 36 to 48 mos. in the combined modality group; none in the chemotherapy group. Combined treatment cases did not show untolerable myelodepression. In 10 long-surviving patients a marked subcutaneous and skin fibrosis developed because of drug additive effect. Stage IV breast cancers rendered clinically free of disease with x-irradiation and subsequently treated with chemotherapy survive significantly longer than with chemotherapy alone

    Standard therapeutic options for patients with relapsed or refractory peripheral T cell lymphoma-not otherwise specified (PTCL-NOS) remain unclear. There are few large cohort studies specifically focused on gemcitabine-based chemotherapy for PTCL-NOS. We retrospectively reviewed patients with relapsed or refractory PTCL-NOS who received salvage GDP (gemcitabine, dexamethasone, and cisplatin) chemotherapy at the Cancer Hospital, Chinese Academy of Medical Sciences (CAMS) and Peking Union Medical College (PUMC), Beijing, China, from May 2008 to August 2014. Twenty-five patients were enrolled and analyzed. The median number of cycles of GDP chemotherapy per patient was four (range, 2-8 cycles). Overall response rate was 64.0% (16/25) with five achieved complete remission or complete remission unconfirmed. After a median follow-up of 9 months, median overall survival (OS) and progression-free survival after relapse or progression (second-PFS) were 9.3 and 5.4 months. One-year PFS rate and 1-year OS rate were 27.4% and 43.9%, respectively. Median second-PFS was significantly longer in patients sensitive to GDP than the ones resistant to the treatment (10.3 vs. 2.8 months, p GDP including neutropenia (8/25), thrombocytopenia (5/25), and anemia (4/25). Taken together, our study suggests that GDP is an effective and optional salvage regimen for relapsed or refractory PTCL-NOS.

    Background and purpose: A retrospective study comparing chemotherapy and radiation, esophagectomy alone versus preoperative radiochemotherapy and surgery in localized squamous-cell esophageal carcinoma. Materials and methods: Between 1989 and 1995, 139 patients (40 stage I, 77 stage IIA and 22 stage IIB according to the UICC 78 TNM classification) were treated in two different institutions. They were divided into three groups according to the treatment proposed: E group (treatment by esophagectomy; n=30), RCT+E group (treatment by preoperative radiochemotherapy and esophagectomy; n=46), RCT group (treatment by radiochemotherapy; n=63). Factors like age, tumor localization and stage were similar in all groups. An intention to treat analysis was made. Results: The E group showed no postoperative mortality, while in the RCT+E group, the surgery mortality was 12.8%. The mortality after RCT was 1.7%. After preoperative radiochemotherapy, a pathological complete response was observed in 25% of cases and the curative resection rate was higher (82% after RCT+E versus 60% after E). The 5-year survival difference between the three groups was not relevant (E group, 12.6%; RCT group, 25.8%; RCT+E group, 38.7%). The median survival was 29, 24 and 28.5 months, respectively. The event-free survival was identical for the E group and the RCT group. For patients treated by radiochemotherapy, local and/or distant relapses were significantly reduced by esophagectomy (relapses occurred in 51% of patients in the RCT+E group versus 75% in the RCT group, P=0.017). Palliative care (dilatations, prosthesis, gastrostomy or jejunostomy) to improve dysphagia was necessary for 38% of patients treated by exclusive radiochemotherapy versus 11% of patients treated by surgery (P=0.001). Conclusions: Treatments by esophagectomy or radiochemotherapy were not significantly different. Preoperative radiochemotherapy and surgery lead to a higher survival rate than exclusive radiochemotherapy, however

    Purpose: To determine which clinical, biological, or treatment-related factors of the first and second primary breast cancers influenced the outcome following contralateral breast carcinoma (CBC). Methods and Materials: By August 1994, 319 of 6406 patients with clinical Stage 0 to III breast carcinoma treated between 1981 and 1987 at Institut Curie had developed a second breast cancer that was diagnosed more than 6 months following ipsilateral breast cancer. Of these 319 patients, 235 had a CBC as the first recurrent event and constitute the study population. Comparisons of first and second breast tumor characteristics were done using Fisher's exact test. Survival distributions from the date of CBC were compared by the log-rank test. Prognostic factors for local relapses, distant relapses, and survival after CBC were assessed by univariate and multivariate analysis using the Cox proportional hazards model. Results: The diagnosis of CBC was more frequently guided by mammographies than for ipsilateral tumors (p 5 years) had no influence on survival. Cox model analysis showed that the risk factors for distant metastases were stage and progesterone receptor levels of the contralateral tumor. The risk of distant failure in CBC was not influenced by the extent of surgery. Conclusions: In this selected population of CBCs as first recurrent events, a follow-up policy based on clinical examination and annual mammography enabled the detection of CBCs at an earlier stage than the primary ipsilateral cancer. The outcome after CBC was determined only by the characteristics of the contralateral tumor. Breast-conserving treatment should be recommended when it is feasible. Adjuvant chemotherapy should be delivered according to the same criteria as the primary tumor

    Salvage of young patients with follicular lymphoma (FL) after R-CHOP includes salvage immunochemotherapy followed by autologous stem cell transplantation (ASCT). Previous studies dealing with relapsed Hodgkin lymphoma have shown the prognostic value of PET/CT prior to ASCT. We retrospectively analysed 59 patients with refractory/relapsed FL after first-line R-CHOP who were chemosensitive (as evaluated by CT) to the salvage treatment and who proceeded to ASCT. The role of PET/CT in this setting to define chemosensitivity is not definitely established. So we focused on the prognostic value of PET/CT performed after salvage treatment, before ASCT. The estimated 3-year progression-free survival (PFS) and overall survival were 63.1 % (50.9-78.3 %) and 90.5 % (82.8 - 98.8 %), respectively, and did not differ significantly according to their Follicular Lymphoma International Prognostic Index at relapse, conditioning regimen, or type of salvage. PFS was significantly lower in PET/CT-positive patients, according to the International Harmonization Project revised response criteria, with a 3-year PFS of 45.5 % (26.6 - 77.8 %) versus 72.6 % (58.5 - 90.0 %; p = 0.039). To better refine prognosis, we applied two types of thresholds: a Deauville five-point scale positive threshold of ≥3 (3-year PFS of 74.9 %, range 61.0 - 92.1 % %, versus 42.8 %, range 24.7 - 74.4 %; p = 0.02), and a ≥70 % ∇SUV{sub max} threshold between presalvage and pre-ASCT PET/CT (3-year PFS of 72.4 %, range 57.5 - 91.3 % versus 13.3 %, 2.2 - 81.7 %; p < 10{sup -3}). The PET/CT findings before ASCT were independently correlated with PFS in our series. PET/CT negativity before ASCT is a desirable and achievable goal in the management of chemosensitive FL relapsing after first-line R-CHOP. (orig.)

    Acidovorax citrulli, the causal agent of bacterial fruit blotch (BFB) of cucurbits has been observed to survive for >34 years in stored melon and watermelon seeds. To better understand this remarkable longevity, we investigated the bacterium's tolerance to desiccation and the effect of bacterial localization in different watermelon seed tissues on its survival. We compared the ability of A. citrulli to tolerate desiccation on filter paper discs and on host (watermelon) and nonhost (cabbage, corn and tomato) seeds to two seedborne (Xanthomonas campestris pv. campestris and Pantoea stewartii subsp. stewartii) and one soilborne (Ralstonia solanacearum) plant-pathogenic bacteria. A. citrulli survival on dry filter paper (>12 weeks) was similar to that of X. campestris pv. campestris but longer than P. stewartii subsp. stewartii. Ralstonia solanacearum survived longer than all other bacteria tested. On all seeds tested, A. citrulli and X. campestris pv. campestris populations declined by 5 orders of magnitude after 12 weeks of incubation at 4°C and 50% relative humidity, while R. solanacearum populations declined by 3 orders. P. stewartii subsp. stewartii was not recovered after 12 weeks of incubation. To determine the effect of tissue localization on bacterial survival, watermelon seeds infested with A. citrulli by flower stigma inoculation (resulting in bacterial localization in the embryo/endosperm) or by ovary pericarp inoculations (resulting in bacterial localization under the testa) were treated with peroxyacetic acid or chlorine (Cl2) gas. Following these treatments, a significantly higher reduction in BFB seed-to-seedling transmission was observed for seeds generated by ovary pericarp inoculation (≥89.5%) than for those generated by stigma inoculation (≤76.5%) (Pseed coat, suggesting that tissue localization is important for bacterial survival in seed. This observation was confirmed when P. stewartii subsp. stewartii survived significantly longer in stigma

    between the BCT, UCT, and BMAST groups with respect to age, histology, clinical stage, primary tumor size, axillary nodal status, or adjuvant systemic therapy. As noted below, there were no statistically significant differences between the three study groups with respect to overall survival, disease-free survival, distant metastasis-free survival, or local regional relapse-free survival. It is noteworthy that there was no significant difference between the local breast relapse rate and the chest wall relapse rate when comparing the conservatively treated group and the bilateral mastectomy group. Conclusions: Patients with bilateral breast carcinoma presenting either synchronously or metachronously are suitable candidates for bilateral conservative treatment. Outcome of these patients with respect to all measurable endpoints did not significantly differ from patients treated conservatively for unilateral breast cancer, or for their counterparts with bilateral disease of similar stage treated with bilateral mastectomy. Of particular note, the 10-year local regional relapse-free rate of patients undergoing bilateral mastectomy did not differ significantly from the local regional relapse rate of those patients treated with bilateral conservative treatment

    Nerve growth factor (NGF) is a neurotrophin and has been suggested to induce heme oxygenase-1 (HO1) expression. Although the role of HO1 in tumorigenesis remains controversial, recent evidence suggests NGF and HO1 as tumor-progressing factors. However, the correlative role of NGF and HO1 and their prognostic impact in breast carcinoma is unknown. We investigated the expression and prognostic significance of the expression of NGF and HO1 in 145 cases of breast carcinoma. Immunohistochemical expression of NGF and HO1 was observed in 31% and 49% of breast carcinoma, respectively. The expression of NGF and HO1 significantly associated with each other, and both have a significant association with histologic grade, HER2 expression, and latent distant metastasis. The expression of NGF and HO1 predicted shorter overall survival of breast carcinoma by univariate and multivariate analysis. NGF expression was an independent prognostic indicator for relapse-free survival by multivariate analysis. The combined expression pattern of NGF and HO1 was also an independent prognostic indicator of overall survival and relapse-free survival. The patients with tumors expressing NGF had the shortest survival and the patients with tumor, which did not express NGF or HO1 showed the longest survival time. This study has demonstrated that individual expression of NGF or HO1, and the combined NGF/HO1 expression pattern could be prognostic indicators for breast carcinoma patients

    Full Text Available Background. To evaluate the outcomes of nasopharyngeal carcinoma (NPC patients treated with helical tomotherapy (HT. Methods. Between September 2007 and August 2012, 190 newly diagnosed NPC patients were treated with HT. Thirty-one patients were treated with radiation therapy as single modality, 129 with additional cisplatin-based chemotherapy with or without anti-EGFR monoclonal antibody therapy, and 30 with concurrent anti-EGFR monoclonal antibody therapy. Results. Acute radiation related side effects were mainly grade 1 or 2. Grade 3 and greater toxicities were rarely noted. The median followup was 32 (3–38 months. The local relapse-free survival (LRFS, nodal relapse-free survival (NRFS, distant metastasis-free survival (DMFS, and overall survival (OS were 96.1%, 98.2%, 92.0%, and 86.3%, respectively, at 3 years. Cox multivariate regression analysis showed that age and T stage were independent predictors for 3-year OS. Conclusions. Helical tomotherapy for NPC patients achieved excellent 3-year locoregional control, distant metastasis-free survival, and overall survival, with relatively minor acute and late toxicities. Age and T stage were the main prognosis factors.

    To evaluate the efficacy of methotrexate (MTX) and the effect of its withdrawal on relapse rate of uveitis associated with juvenile idiopathic arthritis (JIA). Retrospective case series. Data of 22 pediatric JIA patients who were being treated with MTX for active uveitis were studied retrospectively. Relapse rate after the withdrawal of MTX was established. Anterior chamber (AC) inflammation, topical steroid use during the first year of MTX treatment, and associations of relapses after the withdrawal were evaluated statistically. Duration of MTX treatment and its withdrawal was determined individually in collaboration with a rheumatologist with an intention to continue the treatment for at least 1 year and to withdraw in case of inactivity of uveitis and arthritis. Inactivity of uveitis was defined as the presence of ≤0.5+ cells in the AC. Eighteen patients (18/22; 82%) showed improvement of their uveitis with a significant decrease in activity of AC inflammation after a minimal period of 3 months of MTX treatment. A topical steroid-sparing effect was observed when MTX was administered for a period of 3 to 9 months. MTX was discontinued because of inactive uveitis in 13 patients. In 9 patients (8/13; 69%) a relapse of uveitis was observed after a mean time of 7.5 months (± SD 7.3). Six patients (6/13; 46%) had a relapse within the first year after the withdrawal. Relapse-free survival after withdrawal of MTX was significantly longer in patients who had been treated with MTX for more than 3 years (P = .009), children who were older than 8 years at the moment of withdrawal (P = .003), and patients who had an inactivity of uveitis of longer than 2 years before withdrawal of MTX (P = .033). Longer inactivity under MTX therapy was independently protective for relapses after the withdrawal (hazard ratio = 0.07; 95% confidence interval 0.01-0.86; P = .038), which means that 1-year increase of duration of inactive uveitis before the withdrawal of MTX results in a

    The objective of this study was to compare the survival, gastrointestinal (GI) and genitourinary (GU) toxicity for localized or locally advanced prostate cancer treated by high-dose-rate-brachytherapy (HDR-BT) plus external beam radiotherapy (EBRT) versus EBRT alone at a single institute in Taiwan. Eighty-eight patients with T1c-T3b prostate cancer consecutively treated by EBRT alone (33 patients) or HDR-BT+EBRT (55 patients) were studied. The median dose of EBRT was 70.2 Gy in the EBRT group and 50.4 Gy in the HDR-BT group. HDR-BT was performed 2-3 weeks before EBRT, with 12.6 Gy in three fractions over 24 h. Five patients (15.2%) in the EBRT group and seven (12.7%) in the HDR-BT group developed a biochemical relapse. The 5-year actuarial biochemical relapse-free survival rates were 65.0% in the EBRT group and 66.7% in the HDR-BT group (P=0.76). The 5-year actuarial likelihood of late ≥Grade 2 and ≥Grade 3 GI toxicity in the EBRT versus HDR-BT group was 62.8 versus 7.7% (P<0.001) and 19.6 versus 0% (P=0.001), respectively. In a multivariate analysis, the only predictor for late GI toxicity was the mode of RT. The 5-year actuarial likelihood of late ≥Grade 2 and ≥Grade 3 GU toxicity in the EBRT versus HDR-BT group was 14.8 versus 15.9% (P=0.86) and 3.6 versus 8.5% (P=0.40), respectively. The addition of HDR-BT before EBRT with a reduced dose from the EBRT produces a comparable survival outcome and GU toxicity but a significantly less GI toxicity for prostate cancer patients.

    Incorporation of the anti-CD20 monoclonal antibody rituximab into front-line regimens for diffuse large B-cell lymphoma (DLBCL) has resulted in improved survival. Despite this progress, many patients develop refractory or recurrent DLBCL and then receive autologous hematopoietic stem cell transplantation (AuHCT). It is unclear to what extent pre-transplant exposure to rituximab affects outcomes following AuHCT. Outcomes of 994 patients receiving AuHCT for DLBCL between 1996 and 2003 were analyzed according to whether rituximab was (n=176, “+R” group) or was not (n=818, “ −R” group) administered with front-line or salvage therapy prior to AuHCT. The +R group had superior progression-free survival (50% versus 38%, p=0.008) and overall survival (57% versus 45%, p=0.006) at 3 years. Platelet and neutrophil engraftment were not affected by exposure to rituximab. Non-relapse mortality (NRM) did not differ significantly between the +R and −R groups. In multivariate analysis, the +R group had improved progression-free survival (relative risk of relapse/progression or death 0.64, p<0.001) and improved overall survival (relative risk of death of 0.74, p=0.039). We conclude that pre-transplant rituximab is associated with a lower rate of progression and improved survival following AuHCT for DLBCL, with no evidence of impaired engraftment or increased NRM.

    Transfusions represent one of the main progresses of modern medicine. However, accumulating evidence supports that transfusions correlate with worse survival outcomes in patients affected by solid cancers. In the present study, we aimed to investigate the effects of perioperative blood transfusion in locally advanced cervical cancer. Data of consecutive patients affected by locally advanced cervical cancer scheduled to undergo neoadjuvant chemotherapy plus radical surgery were retrospectively searched to test the impact of perioperative transfusions on survival outcomes. Five-year survival outcomes were evaluated using Kaplan-Meier and Cox models. The study included 275 patients. Overall, 170 (62%) patients had blood transfusion. Via univariate analysis, we observed that transfusion correlated with an increased risk of developing recurrence (hazard ratio [HR], 2.2; 95% confidence interval [CI], 1.09-4.40; P = 0.02). Other factors associated with 5-year disease-free survival were noncomplete clinical response after neoadjuvant chemotherapy (HR, 2.99; 95% CI, 0.92-9.63; P = 0.06) and pathological (P = 0.03) response at neoadjuvant chemotherapy as well as parametrial (P = 0.004), vaginal (P < 0.001), and lymph node (P = 0.002) involvements. However, via multivariate analysis, only vaginal (HR, 3.07; 95% CI, 1.20-7.85; P = 0.01) and lymph node involvements (HR, 2.4; 95% CI, 1.00-6.06; P = 0.05) correlate with worse disease-free survival. No association with worse outcomes was observed for patients undergoing blood transfusion (HR, 2.71; 95% CI, 0.91-8.03; P = 0.07). Looking at factors influencing overall survival, we observed that lymph node status (P = 0.01) and vaginal involvement (P = 0.06) were independently associated with survival. The role of blood transfusions in increasing the risk of developing recurrence in LAAC patients treated by neoadjuvant chemotherapy plus radical surgery remains unclear; further prospective studies are warranted.

    For pediatric patients with acute lymphoblastic leukemia (ALL), relapse is an important cause of treatment failure after unrelated cord blood transplant (UCBT). Compared with other donor sources, relapse is similar or even reduced after UCBT despite less graft-versus-host disease (GVHD). We performed a retrospective analysis to identify risk factors associated with the 5-year cumulative incidence of relapse after UCBT. In this retrospective, registry-based study, we examined the outcomes of 640 children (leukemia-free survival (LFS), and relapse were 59%, 52%, and 23%, respectively. In multivariate analysis (MVA), acute GVHD (grades II to IV) and TBI protected against relapse. In patients in CR2, rates of 5-year OS, LFS, and the cumulative incidence of relapse were 46%, 44%, and 28%, respectively. In MVA, longer duration from diagnosis to UCBT (≥30 months) and TBI were associated with decreased relapse risk. Importantly, receiving a fully HLA matched graft was a strong risk factor for increased relapse in MVA. An exploratory analysis of all 640 patients supported the important association between the presence of acute GVHD and less relapse but also demonstrated an increased risk of nonrelapse mortality. In conclusion, the impact of GVHD as a graft-versus-leukemia marker is evident in pediatric ALL after UCBT. Strategies that promote graft-versus-leukemia while harnessing GVHD should be further investigated. Copyright © 2017 The American Society for Blood and Marrow Transplantation.

    Given that 30-40% of children with acute myeloid leukaemia (AML) relapse after primary therapy it is important to define prognostic factors and identify optimal therapy. From 1993 to 2012, 543 children from the Nordic countries were treated according to two consecutive protocols: 208 children...... relapsed. The influence of disease characteristics, first line treatment, relapse therapy and duration of first remission on outcome was analysed. Second complete remission (CR2) was achieved in 146 (70%) patients. Estimated 5-year overall survival (OS5y ) was 39 ± 4% for the whole group and 43 ± 4......, no allogeneic stem cell transplantation (SCT) in first remission and core binding factor AML were independent favourable prognostic factors for survival. For the 128 children (124 in CR2) that received SCT as consolidation therapy after relapse, OS5y was 61 ± 5%. Four of 19 children (21%) survived without...

    Chemotherapy and primary site radiation therapy were compared to chemotherapy alone in a randomized study of 125 patients with small cell cancer of the lung. The sites of initial relapse, as well as disease free and overall survival were analyzed. Radiotherapy to the primary site reduced the rate of local relapse, but median survival was not prolonged in patients with either limited or extensive disease, when the radiation therapy-chemotherapy group was compared to the group that received chemotherapy alone

    Purpose. - Retrospective study of 23 patients treated with conformal radiotherapy for a locally advanced bile duct carcinoma. Patients and methods. - Eight cases were irradiated after a radical resection (RO), because they were N+; seven after microscopically incomplete resection (R1) ; seven were not resected (R2). A dose of 45 of 50 Gy was delivered, followed by a boost up to 60 Gy in R1 and R2 groups. Concomitant chemotherapy was given in 15 cases. Results.-Late toxicity included a stenosis of the duodenum, and one of the biliary anastomosis. Two patients died from cholangitis, the mechanism of which remains unclear. Five patients are in complete remission, six had a local relapse, four developed a peritoneal carcinosis, and six distant metastases. Actuarial survival rate is 75%, 28% and 7% at 1, 3 and 5 years, respectively (median: 16.5 months). Seven patients are still alive with a 4 to 70 months follow-up. Survival is similar in the 3 small subgroups. The poor local control among RON+ cases might be related to the absence of a boost to the 'tumor bed'. In R1 patients, relapses were mainly distant metastases, where'as local and peritoneal recurrences predominated in R2. Conclusion. - Conformal radio-chemotherapy delivering 60 Gy represents a valuable palliative approach in locally advanced biliary carcinoma. (authors)

    Purpose: This prospective, randomized trial in extensive, untreated Hodgkin's disease was undertaken to assess the potential benefit of augmented therapy (12 months chemotherapy or radiation to 'bulk' disease) compared to standard, six months chemotherapy. Materials and Methods: Two-hundred fifty-eight patients, mostly stage IV, were randomized to four treatment regimens consisting of 6 cycles of CCNU, vinblastine, procarbazine, and prednisone (CVPP); 12 cycles of CVPP; 6 cycles of CVPP followed by 25 Gray (Gy) radiotherapy; or 3 cycles CVPP, 25 Gy radiotherapy, and 3 cycles CVPP. Results: Complete remissions were achieved in 65% of all patients. A 58% overall 5 year survival was obtained. Relapses in irradiated areas of bulk disease occurred in only 6% of responding patients. There was, however, no statistical difference in response frequency, disease free survival or overall survival amongst the four regimens. Elderly patients responded less frequently. Conclusion: While radiotherapy provided control of local (bulk) disease, no impact on overall survival was apparent. Likewise doubling the duration of chemotherapy did not improve response or survival. Augmentation of therapy with either radiotherapy or more chemotherapy in this study was of no benefit when compared to the standard six months of treatment

    Purpose: To evaluate the clinical outcomes and late effects of radiation therapy (RT) in localized primary orbital mucosa-associated lymphoma tissue (MALT) lymphoma (POML). Methods and Materials: From 1989 to 2007, 89 patients with Stage IE POML received RT. The median age was 56 years old. Sites involved conjunctiva (59 patients [66%]), lacrimal gland (20 patients [23%]), and soft tissue (10 patients [11%]). Megavoltage beam(s) was used in 91%, electrons in 7%, and orthovoltage in 2% of cases. The dose given was 25 Gy in 97% and 30 Gy in 3% of patients. Lens shielding was possible in 57% of patients. Results: The median follow-up was 5.9 years. Complete response or unconfirmed complete response was seen in 88 patients (99%). Relapse occurred in 22 patients (25%). First relapse sites were local (2 patients [9%]), in the contralateral orbit (5 patients [23%]), and distant (15 patients [68%]). The 7-year overall survival (OS), cause-specific survival (CSS), relapse-free survival (RFS), and local control (LC) rates were 91%, 96%, 64%, and 97%, respectively. Radiation-related late sequelae were documented in 40 patients (45%). Cataracts were observed in 22 patients (Grade 1 in 2 patients; Grade 3 in 20 patients). The incidence of Grade 3 cataract at 7 years was 25%. Other late sequelae (n = 28) were dry eye(s) (22 patients [Grade 1 in 14 patients; Grade 2 in 2 patients; Grade 3 in 2 patients; n/s in 4 patients), keratitis (3 patients), macular degeneration/cystoid edema (2 patients), and vitreous detachment (1 patient). Five patients developed Grade 3 noncataract late effects. Lens shielding reduced the incidence of Grade 3 cataract and all Grade {>=}2 late sequelae. Seventeen patients (16 with cataracts) underwent surgery; 23 patients were treated conservatively. The outcome for managing late effects was generally successful, with 30 patients completely improved, and 9 patients with persisting late sequelae (10%). Conclusions: POML responds favorably to moderate doses

    Purpose: This study retrospectively assesses the patterns of failure in conservatively treated early stage breast cancer patients by correlating various clinical, pathologic, and treatment-related factors with local, axillary, and distant relapse. Methods and Materials: Between 1973 and 1990, 796 patients (817 breasts) received breast conservation surgery followed by radiotherapy. Local recurrences were counted as events even if they occurred simultaneously or after the appearance of axillary or distant metastases. Results: The 10-year actuarial relative disease-free survival (DFS) rate for T1N0, T2N0, and T1-2N1 was 82%, 71%, and 54%, respectively. Stage N0 patients had a significant DFS advantage over N1 patients (p = 0.02). The 15-year actuarial local recurrence-free rate for T1 and T2 tumors was 82% and 87%, respectively (p = nonsignificant). Univariate analysis identified three significant risk factors for local relapse: (a) 48 breasts with tumors showing an extensive intraductal component had a crude local recurrence rate of 23% compared to 8% for 769 breasts without intraductal component (p 0.0016); (b) the actuarial 10-year local recurrence-free rate for patients under age 40 years was 64% compared to 88% for patients over 40 years (p < 0.0001); (c) the 10-year actuarial local recurrence-free rate for 416 postmenopausal women without adjuvant tamoxifen was 83% compared to 97% for 107 postmenopausal women with tamoxifen (p = 0.0479). Salvage therapy for operable local recurrent patients resulted in a 8-year actuarial DFS rate of 47%, significantly lower than that obtained with primary treatment. The incidence of axillary relapse as the first sign of recurrence was 2%, and could be correlated with the lack of axillary dissection (p < 0.0000005) and primary tumor size (p = 0.03). Radiotherapy to the axilla did not influence axillary relapse. Actuarial 5-year DFS rate after treatment of isolated axillary recurrence was 27%. Axillary failure was a marker for

    The purpose of this study is to analyze the clinical impact of radical nephrectomy on retroperitoneal liposarcoma near the kidney. Data of patients who underwent surgery for unilateral primary retroperitoneal liposarcoma near the kidney were retrospectively collected. Patients were divided into four groups according to whether they underwent nephrectomy and combined resection of other organs. Kaplan-Meier survival analysis was used to estimate disease-free survival and overall survival. Multivariable Cox analysis was used to analyze factors related to disease-free survival and overall survival. Nephrectomy (HR = 0.260, CI = 0.078-0.873, p = 0.029) had a beneficial effect on disease-free survival, while interaction model of nephrectomy*other organ resection (HR = 4.655, CI = 1.767-12.263, p = 0.002) showed poor disease-free survival. Other organ resection was not related to disease-free survival (HR = 1.543, CI = 0.146-16.251, p = 0.718). Operation method (p = 0.007) and FNCLCC grade (p free survival. While combined organ resection without nephrectomy group (HR = 1.604, CI = 0.167-15.370, p = 0.682) and radical nephrectomy with combined organ resection group (HR = 1.309, CI = 0.448-3.825, p = 0.622) did not show significant difference in disease-free survival from the mass excision only group, radical nephrectomy without combined organ resection group (HR = 0.279, CI = 0.078-0.991, p = 0.048) showed superior disease-free survival. Radical nephrectomy of unilateral primary retroperitoneal liposarcoma near the kidney has a beneficial effect on disease-free survival.

    Purpose: To determine the outcome and prognostic factors for patients with localized epithelioid sarcoma treated with conservative surgery and radiotherapy (RT). Methods and Materials: The medical records of 24 patients with nonmetastatic epithelioid sarcoma treated with conservative surgery and RT were reviewed. Preoperative RT was given to 3 patients (median 46.4 Gy) and postoperative RT to 21 patients (median 64.5 Gy). A local (limb-sparing) surgical procedure was performed in all patients. Results: At a median follow-up of 131 months, 14 patients had relapsed and 13 patients had died. The actuarial overall and disease-free survival rate at 10 years was 50% and 37%, respectively. Local, nodal, and metastatic failure occurred in 7, 4, and 10 patients, respectively, yielding a 10-year actuarial local, nodal, and metastatic control rate of 63%, 81%, and 56%, respectively. Univariate analysis revealed that size ≤5 cm and extremity location were favorable prognostic factors for overall, disease-free, and metastasis-free survival. The actuarial 5-year overall, disease-free, and metastasis-free survival rate was 79% vs. 25% (p=0.002), 51% vs. 13% (p=0.03), and 79% vs. 13% (p 5 cm. The actuarial 5-year overall, disease-free, and metastasis-free survival rate was 77% vs. 39% (p 0.002), 56% vs. 0% (p=0.01), and 78% vs. 17% (p=0.01), respectively, for extremity vs. nonextremity location. Multivariate analysis of the factors correlating with the overall, disease-free, and metastasis-free survival confirmed the favorable prognostic significance of small lesion size. The prognostic significance of extremity location on univariate analysis was explained by an imbalance in the mean tumor sizes. Conclusions: Epithelioid sarcoma is an aggressive soft-tissue sarcoma, with high rates of local and distant relapse. Local control with conservative surgery and RT compares favorably to published surgical series. The poor outcome for tumors ≥5 cm in size emphasizes the need for

    Relapsed acute lymphoblastic leukemia (ALL) represents a major cause of morbidity and mortality in pediatrics. With contemporary chemotherapy, >85% of patients with newly diagnosed ALL survive. Unfortunately, 20% of these patients will relapse and for these children, outcomes remain poor despite our best known chemotherapy protocols. Most of these children will achieve a second complete remission, but maintaining this remission remains difficult. Because relapsed ALL is such a significant cause of morbidity and mortality, it is the focus of much research interest. Efforts have been made and continue to focus on understanding the underlying biology that drives relapse. The role of hematopoietic stem cell transplantation in relapsed ALL remains unclear, but many clinicians still favor this for high-risk patients given the poor prognosis with current chemotherapy alone. It is important to use new drugs with little cross-resistance in the treatment of relapsed ALL. New classes of agents are currently being studied. We also discuss prognostic factors and the biology of relapsed ALL.

Patients and Methods: Fifty-three patients were treated between 1971 and 2006. Thirty patients were treated with radiotherapy (RT) alone and 23 patients were treated with surgery ± RT. Larger tumors and tumors of the femur were treated more often with definitive RT. Median potential follow-up was 19.2 years. Functional outcome was assessed using the Toronto Extremity Salvage Score (TESS). Results: Before 1985, 24% of patients were treated with surgery; since then, the rate has increased to 61%. The 15-year actuarial overall survival (OS), cause-specific survival (CSS), freedom from relapse, and limb preservation rates were 68% vs. 47% (p = 0.21), 73% vs. 47% (p = 0.13), 73% vs. 40% (p = 0.03), and 43% vs. 40% (p = 0.52), respectively, for patients treated with surgery ± RT vs. RT alone. Excluding 8 patients who underwent amputation or rotationplasty, the 15-year actuarial local control rate was 100% for the surgery ± RT group and 68% for the definitive RT group (p = 0.03). The ranges of the TESS for surgery ± RT vs. RT alone were 70-100 (mean, 94) and 97-100 (mean, 99), respectively. Twenty-six percent (6/23) of patients had complications related to surgery requiring amputation or reoperation. Conclusions: Overall survival and CSS were not statistically compromised, but we observed an increased risk of relapse and local failure in patients treated with RT alone, thereby justifying a transition toward primary surgical management in suitable patients. However, despite an adverse risk profile, patients treated with RT alone had similar long-term amputation-free survival and demonstrated comparable functional outcomes. Poor results observed in Ewing's of the femur mandate innovative surgical and RT strategies

    To assess the associations between incident atrial fibrillation (AF) and disability-free survival and risk of disability. Prospective cohort study. Cardiovascular Health Study. Individuals aged 65 and older and enrolled in fee-for-service Medicare followed between 1991 and 2009 (MN = 4,046). Individuals with prevalent AF, activity of daily living (ADL) disability, or a history of stroke or heart failure at baseline were excluded. Incident AF was identified according to annual study electrocardiogram, hospital discharge diagnosis, or Medicare claims. Disability-free survival was defined as survival free of ADL disability (any difficulty or inability in bathing, dressing, eating, using the toilet, walking around the home, or getting out of a bed or chair). ADLs were assessed at annual study visits or in a telephone interview. Association between incident AF and disability-free survival or risk of disability was estimated using Cox proportional hazards models. Over an average of 7.0 years of follow-up, 660 individuals (16.3%) developed incident AF, and 3,112 (77%) became disabled or died. Incident AF was associated with shorter disability-free survival (hazard ratio (HR) for death or ADL disability = 1.71, 95% confidence interval (CI) = 1.55-1.90) and a higher risk of ADL disability (HR = 1.36, 95% CI = 1.18-1.58) than in individuals with no history of AF. This association persisted after adjustment for interim stroke and heart failure. These results suggest that AF is a risk factor for shorter functional longevity in older adults, independent of other risk factors and comorbid conditions. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Purpose: Pretreatment hemoglobin (Hb) level has been reported to be an important prognostic factor for local control and survival in various malignancies. However in many settings, the adverse effect of a low Hb may be related to more advanced disease and the purpose of this analysis was to assess the influence of pretreatment Hb on local control in a large series of patients with a localised cancer (T1/T2 glottic cancer, AJCC 1992) treated in a standard fashion. Materials and Methods: Between Jan 1981 and Dec 1989, 735 patients (median age 63, 657 males 78 females) with T1/T2 glottic cancer were treated with RT. The standard RT prescription was 50Gy in 20 fractions over 4 weeks (97% patients). Factors studied for prognostic importance for local failure included pretreatment Hb (assessed as a continuous variable) age, sex, T category, anterior commissure involvement, subglottic extension, tumour bulk (presence of visible tumour vs subclinical disease), treatment time and RT technique (Cobalt vs 6 MV). Results: With a median follow-up of 6.8 years (range 0.2 - 14.3), 131 patients have relapsed for an actuarial 5-year relapse free rate of 81.7%. The 5-year actuarial survival was 75.8%, cause specific survival - 92.4%. The median pretreatment hemoglobin level was 14.8 g/dl and was the same in all T categories. On multivariate analysis, using the Cox proportional hazards model, pretreatment Hb (p=0.001) predicted for local failure after RT. The relative risk (RR) for relapse was calculated for various Hb levels eg the RR for a Hb of 12 g/dl vs a Hb of 15 g/dl was 1.8, (95% C.I. 1.3 - 2.7). Previously noted factors including gender (p=0.0038), T category (p=0.007)) as well as tumour bulk (p=0.02) were also prognostically important for local control. Conclusions: This analysis, in a large number of similarly treated patients, indicates that pretreatment Hb is an independent prognostic factor for local control in patients with T1/T2 carcinoma of the glottis treated with

    Purpose. - Retrospective study of 23 patients treated with conformal radiotherapy for a locally advanced bile duct carcinoma. Patients and methods. - Eight cases were irradiated after a radical resection (RO), because they were N+; seven after microscopically incomplete resection (R1) ; seven were not resected (R2). A dose of 45 of 50 Gy was delivered, followed by a boost up to 60 Gy in R1 and R2 groups. Concomitant chemotherapy was given in 15 cases. Results.-Late toxicity included a stenosis of the duodenum, and one of the biliary anastomosis. Two patients died from cholangitis, the mechanism of which remains unclear. Five patients are in complete remission, six had a local relapse, four developed a peritoneal carcinosis, and six distant metastases. Actuarial survival rate is 75%, 28% and 7% at 1, 3 and 5 years, respectively (median: 16.5 months). Seven patients are still alive with a 4 to 70 months follow-up. Survival is similar in the 3 small subgroups. The poor local control among RON+ cases might be related to the absence of a boost to the 'tumor bed'. In R1 patients, relapses were mainly distant metastases, where'as local and peritoneal recurrences predominated in R2. Conclusion. - Conformal radio-chemotherapy delivering 60 Gy represents a valuable palliative approach in locally advanced biliary carcinoma. (authors)

    Full Text Available Background. Primary bone lymphoma (PBL is a rare entity that has only been reviewed in one prospective and small retrospective studies, from which it is difficult to establish treatment guidelines. We prospectively evaluated high-dose or conventional anthracycline-cyclophosphamide dose and radiotherapy for PBL. Patients and Methods. The GOELAMS prospective multicenter study (1986–1998 enrolled adults with localized high-grade PBL according to age and performance status (PS. Patients <60 years received a high-dose CHOP regimen (VCAP and those ≥60 years a conventional anthracycline-cyclophosphamide regimen (VCEP-bleomycin; all received intrathecal chemotherapy and local radiotherapy. Results. Among the 26 patients included (VCAP: 19; VCEP-bleomycin: 7, 39% had poor PS ≥2. With a median follow-up of 8 years, overall survival, event-free survival, and relapse-free survival were 64%, 62%, and 65%, respectively, with no significant difference between treatment groups. Poor PS was significantly associated with shorter OS and EFS. Conclusions. Our results confirm the efficacy of our age-based therapeutic strategy. High-doses anthracycline-cyclophosphamide did not improve the outcome. VCEP-bleomycin is effective and well tolerated for old patients. The intensification must be considered for patients with PS ≥2, a poor prognostic factor.

    Purpose: This study set out to determine the impact of a positive circumferential resection margin (CRM) (R1-R2) and pathologic downstaging on local recurrence and survival in patients with borderline resectable or unresectable rectal adenocarcinoma treated with neoadjuvant chemoradiotherapy (CRT). Methods and Materials: A total of 150 patients with locally advanced rectal cancer were treated with long-course neoadjuvant CRT using low-dose folinic acid and 5-fluorouracil. CRT was followed 6-12 weeks later by surgical excision. The CRM rate and incidence, site, and pattern of local and systemic recurrences were recorded. The median follow-up was 25 months. Results: The overall median survival was 37 months, with a 5-year overall survival rate of 34%. Of the 150 patients, 122 underwent curative resection; 12% had a complete pathologic response, and downstaging to pT1-T2 occurred in an additional 16%. A negative CRM (R0) was achieved in 65% overall (98 of 150). Local recurrence occurred in 10% of those with R0 resection and 62% of those with R1-R2 resections. Distant metastases occurred in 29% of those with R0 resections and 75% of those with R1-R2 resections. The 3-year disease-free and 3-year overall survival rate was 9% and 25% and 52% and 64%, respectively, for patients with and without a histologically positive CRM. Conclusion: After 5-fluorouracil-based CRT, a positive CRM predicted for a high risk of subsequent local recurrence and a 3-year disease-free survival rate of only 9%. For this reason, the CRM should be considered a major prognostic factor and should be validated in future trials as an early alternative clinical endpoint

    Full Text Available Abstract Background In B cell non-Hodgkin lymphoma (B-NHL, rituximab-containing reduced-intensity conditioning regimens (R-RIC have been shown to provide favorable outcomes in single-arm studies; however, large multicenter studies comparing R-RIC and non-rituximab-containing reduced-intensity conditioning regimens (nonR-RIC have not been performed. Using the CIBMTR database, we report the outcomes of R-RIC versus nonR-RIC regimens in B-NHL. Methods We evaluated 1401 adult B-NHL patients undergoing allogeneic hematopoietic cell transplantation (allo-HCT who received nonR-RIC (n = 1022 or R-RIC (n = 379 regimens. Graft-versus-host disease (GVHD prophylaxis was limited to calcineurin inhibitor-based approaches. Results Median follow-up of survivors in the R-RIC and nonR-RIC groups was 47 and 37 months, respectively. On multivariate analysis, no difference was seen between the R-RIC and nonR-RIC cohorts in terms of acute GVHD grade II–IV (RR = 1.14, 95%CI = 0.83–1.56, p = 0.43 or grade III–IV (RR = 1.16, 95%CI = 0.72–1.89, p = 0.54, chronic GVHD (RR = 1.15, 95%CI = 0.92–1.46, p = 0.22, non-relapse mortality (RR = 0.90; 95%CI = 0.67–1.22; p = 0.51, relapse/progression (RR = 0.79; 95%CI = 0.63–1.01; p = 0.055, and mortality (RR = 0.84, 95%CI = 0.69–1.02, p = 0.08 risk. However, R-RIC was associated with a significantly improved progression-free survival (RR = 0.76; 95%CI 0.62–0.92; p = 0.006. On subgroup analysis, mortality benefit was noted in the R-RIC group patients not receiving busulfan-based RIC (RR = 0.76; 95%CI = 0.60–0.96; p = 0.02 and with the use of a higher cumulative rituximab dose (RR = 0.43; 95%CI = 0.21–0.90; p = 0.02. Conclusion Our analysis shows that inclusion of rituximab in RIC regimens improves progression-free survival in patients with B cell NHL. These data supports the use of R-RIC in B

    Purpose. -To retrospectively evaluate survival, progression free survival (PFS) and biological response in a series of patients irradiated with mixed neutron/photon beams for locally advanced prostate cancer in our institution. Patients and methods. - Three hundred and eight patients were treated between January 1990 and December 1996. Fifty-five of these were recruited for pT3 or pN1 tumors after radical prostatectomy. Neo-adjuvant androgen deprivation was given in 106 patients. The treatment protocol consisted of a mixed photon/neutron irradiation in a two-to-three proportion, up to a total equivalent dose of 66 Gy (assuming a clinical RBE value of 2.8). Pre- and post-treatment PSA determinations were available in practically all cases. Study endpoints were overall survival (OAS) and progression-free survival (PFS). The Cox proportional hazard regression model was used to investigate the prognostic value of baseline characteristics on survival and progression-free survival were a progression was defined as local, regional, metastatic or biological progression. Mean age was 69 years (49-86); mean pretreatment PSA was 15 (0.5-330) in all patients and 14 (0.5-160) in those receiving neo-adjuvant hormonotherapy; seven patients only had an initial PSA S 4 ng/mL; 15% were T1, 46% were T2, 28% were T3 or pT3 and 4% were T4 (7% unspecified); WHO grade of differentiation was I in 38%, II in 38% and III in 14% (5% unspecified). Results. -The median follow-up was 2.8 years (0-7.8). Five year overall survival (OAS) was 79% (95% CI: 71-87%) and 5-year progression-free survival (PFS) was 64% (95% Cl: 54-74%) for the entire series. PFS in patients with an initial PSA >- 20 ng/mL was the same. PFS could be predicted by two optimal Cox regression models, one including histological grade (p = 0.003) and initial PSA (p = 0.0009) as cofactors, the other including histological grade (p = 0.003) and T stage (p = 0.02). The main prognostic factors for overall survival were PSA and age

    The purpose of the present study was to evaluate the association of open and closed Fontan fenestration status with event-free survival. All patients who underwent a fenestrated Fontan procedure at our institution from January 1994 through June 2007 were reviewed. Patient information was obtained from the medical records. The patients were assigned to 1 of 2 study groups, open or closed, according to their most recent fenestration status. Clinically relevant morbid events were tabulated, and Kaplan-Meier event analysis was used to create event-free probability curves with log-rank comparisons. A total of 161 patients were classified as open and 51 as closed. The median interval to an event was 1.1 years (interquartile range, 0.1-3.3 years) after the Fontan procedure. The median interval to closure was 1.2 years (interquartile range, 0.7-3.3 years). The median interval to an event was 1.5 years (interquartile range, 0.1-4.6 years) in the closed group and 1.1 years (interquartile range, 0.1-3.3 years) in the open group. Event-free probability analysis revealed no significant difference between the 2 groups (P = .15). The median follow-up arterial oxygen saturation was greater in the closed group (96.0%; interquartile range, 94.0%-97.0%) than in the open group (91.0%; interquartile range, 86.0%-95.0%; P < .0001). Fenestration closure was associated with greater arterial oxygen saturation but not greater event-free survival. The interval to an event was slightly less than the interval to fenestration closure, suggesting potential merit in the evaluation of earlier fenestration closure. Adoption of specific fenestration management guidelines might help improve the overall outcomes and enhance the quality of future studies.

    Hospital closures became a prevalent phenomenon in Taiwan after the implementation of a national health insurance program. A wide range of causes contributes to the viability of hospitals, but little is known about the situation under universal coverage health systems. The purpose of present study is to recognize the factors that may contribute to hospital survival under the universal coverage health system. This is a retrospective case-control study. Local community hospitals that contracted with the Bureau of National Health Insurance in 1998 and remained open during the period 1998-2011 are the designated cases. Controls are local community hospitals that closed during the same period. Using longitudinal representative health claim data, 209 local community hospitals that closed during 1998-2011 were compared with 165 that remained open. Variables related to institutional characteristics, degree of competition, characteristics of patients and financial performance were analyzed by logistic regression models. Hospitals' survival was positively related to specialty hospital, the number of respiratory care beds, the physician to population ratio, the number of clinics in the same region, a highly competitive market and the occupancy rate of elderly patients in the hospital. Teaching hospitals, investor-owned hospitals, the provision of obstetrics services or home care, and the number of medical centers or other local community hospitals may jeopardize the chance of survival. Factors-enhanced local hospitals to survive under the universal coverage health system have been identified. Hospital managers could manipulate these findings and adapt strategies for subsistence. © The Author 2015.

    Obesity is a worldwide epidemic in children and adolescents. Adult cohort studies have reported an association between higher body mass index (BMI) and increased leukemia-related mortality; whether a similar effect exists in childhood leukemia remains controversial. We conducted a meta-analysis to determine whether a higher BMI at diagnosis of pediatric acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML) is associated with worse event-free survival (EFS), overall survival (OS), and cumulative incidence of relapse (CIR). We searched 4 electronic databases from inception through March 2015 without language restriction and included studies in pediatric ALL or AML (0-21 y of age) reporting BMI as a predictor of survival or relapse. Higher BMI, defined as obese (≥95%) or overweight/obese (≥85%), was compared with lower BMI [nonoverweight/obese (children with a higher BMI (RR: 1.35; 95% CI: 1.20, 1.51) than in those at a lower BMI. A higher BMI was associated with significantly increased mortality (RR: 1.31; 95% CI: 1.09, 1.58) and a statistically nonsignificant trend toward greater risk of relapse (RR: 1.17; 95% CI: 0.99, 1.38) compared with a lower BMI. In AML, a higher BMI was significantly associated with poorer EFS and OS (RR: 1.36; 95% CI: 1.16, 1.60 and RR: 1.56; 95% CI: 1.32, 1.86, respectively) than was a lower BMI. Higher BMI at diagnosis is associated with poorer survival in children with pediatric ALL or AML. © 2016 American Society for Nutrition.

    Purpose: Evaluate disease control and survival in patients with locally advanced gynecological malignancies who received intraoperative radiation therapy with electrons (IOERT) as a component of treatment. Methods and Materials: Between March 1983 and June 1995, 63 patients (pts) with locally advanced primary (9 pts) or recurrent (54 pts) gynecological malignancies received IOERT as a component of attempted curative therapy. The site of origin was uterine cervix in 40 pts, uterine corpus in 16 pts, vagina in 5 pts, and ovary in 2 pts. Thirty-eight patients with recurrent disease had been previously irradiated (median prior RT dose 5040 cGy, range 900-8400). External beam radiotherapy (EBRT) was given to 43 of 63 pts either before or after IOERT (900-6570 cGy, median 4960 cGy). Chemotherapy was given to 21 pts prior to IOERT and following IOERT in 2 pts. IOERT doses ranged from 800 cGy to 2500 cGy with a median of 1750 cGy. The median IOERT dose was 2000 cGy in 20 patients with gross residual disease and 1500 cGy in 43 patients with microscopic residual disease. Endpoints included central control within the IOERT cone, local control, distant failure, disease free survival and overall survival. Variables evaluated for impact on disease outcome included tumor grade, primary site, prior RT, IOERT dose, EBRT dose, residual disease at time of IOERT, and use of chemotherapy. Results: Survival and disease control data are presented in the table below. There was no impact of any disease or treatment related variable on local or central failure. Pts with microscopic residual disease at the time of IOERT had significantly fewer distant metastases than pts with gross residual (5 yr 31% vs. 77%, p = 0.001) and improved survival (5 yr 37% vs. 10%, p = 0.02). Patients with recurrent disease after previous RT had survival and disease control rates which were similar to those seen in pts without priot RT. Toxicity ≥ grade 3 due to IOERT was observed in 11 pts (17%). Conclusion: A

    Background We analyzed detailed characteristics and salvage treatment in 175 follicular lymphoma patients from the FL2000 study who were in progression after first-line therapy with or without addition of rituximab to chemotherapy and interferon. Design and Methods The impact of using autologous stem cell transplantation and/or rituximab administration at first progression was investigated, taking into account initial therapy. With a median follow up of 31 months, 3-year event free and overall survival rates after progression were 50% (95%CI 42–58%) and 72% (95%CI 64–78%), respectively. Results The 3-year event free rate of rituximab re-treated patients (n=112) was 52% (95%CI 41–62%) versus 40% (95%CI 24–55%) for those not receiving rituximab second line (n=53) (P=0.075). There was a significant difference in 3-year overall survival between patients receiving autologous stem cell transplantation and those not: 92% (95%CI 78–97%) versus 63% (95%CI 51–72%) (P=0.0003), respectively. In multivariate analysis, both autologous stem cell transplantation and period of progression/relapse affected event free and overall survival. Conclusions Regardless of front-line rituximab exposure, this study supports incorporating autologous stem cell transplantation in the therapeutic approach at first relapse for follicular lymphoma patients.

    Full Text Available The aim of our study is to examine the clinical and pathological features of patients with breast phyllodes tumors and to determine features that are correlated to outcome. Forty four phyllodes tumors were assessed. There were 11 benign, 11 borderline and 22 malignant tumors. 10 of 44 patients (22.72 % relapsed at any site. Seven patients (15.9 % had a local recurrence and 3 patients experienced local and metastatic relapse. The 5-year and 10-year survival rates are 97% and 95 % respectively. The 5 years and 10 years DFS are 81% and 77% respectively. Grade, histological size, margin involvement impacted disease free survival. Adjuvant radiation therapy improved local control in high grade tumors although it didn’t reach significance.

    Purpose: To analyze the results of radical radiotherapy by electron beams for squamous cell carcinoma (SCC) of the eyelid and to find the possible prognostic factors. Materials and Methods: Records of 38 patients with histologically confirmed SCC of the eyelid who underwent electron beam radiation therapy between 1964 and 2010 in our institution were retrospectively reviewed. Median tumor size was 15 mm (range, 3–40 mm). T stage was T1 in three, T2a in six, T2b in 14, and T3a in 15 patients. Four patients had nodal metastasis. Of the 38 patients, 14 had relapsed disease after prior treatment. Median radiation dose was 60.0 Gy (range, 45.0–70.4 Gy). Median follow-up was 72.5 months (range, 2.0–369 months). Results: 5-year local relapse-free, nodal relapse-free, distant metastasis-free and relapse-free rates for all patients were 71.8%, 77.5%, 90.6% and 58.0%, respectively. In seven patients, lymph node metastases occurred in 11 faciocervical regions. The 5-year overall survival was 79.5%. T stage and radiation dose expressed in EQD 2 Gy tended to have impacts on local control. Relapsed patients showed unfavorable local relapse-free rate, however this was without statistical significance. Of the 14 patients who died, 12 succumbed to concurrent diseases. Grade 3 or greater severe late morbidities (CTCAE ver4.0) were observed in nine patients. Due to the morbidities, two patients lost their vision. Conclusion: Radical radiotherapy for SCC of the eyelid yielded good results and could be a treatment option. Whether radiation-dose escalation could improve local control in advanced T stages and relapsed patients needs further study

    Purpose: The typically benign, but occasionally rapidly fatal clinical course of papillary thyroid cancer has raised the need for individual survival probability estimation, to tailor the treatment strategy exclusively to a given patient. Materials and methods: A retrospective study was performed on 400 papillary thyroid cancer patients with a median follow-up time of 7.1 years to establish a clinical database for uni- and multivariate analysis of the prognostic factors related to survival (Kaplan-Meier product limit method and Cox regression). For a more precise prognosis estimation, the effect of the most important clinical events were then investigated on the basis of a Markov renewal model. The basic concept of this approach is that each patient has an individual disease course which (besides the initial clinical categories) is affected by special events, e.g. internal covariates (local/regional/distant relapses). On the supposition that these events and the cause-specific death are influenced by the same biological processes, the parameters of transient survival probability characterizing the speed of the course of the disease for each clinical event and their sequence were determined. The individual survival curves for each patient were calculated by using these parameters and the independent significant clinical variables selected from multivariate studies, summation of which resulted in a mean cause-specific survival function valid for the entire group. On the basis of this Markov model, prediction of the cause-specific survival probability is possible for extrastudy cases, if it is supposed that the clinical events occur within new patients in the same manner and with the similar probability as within the study population. Results: The patient's age, a distant metastasis at presentation, the extent of the surgical intervention, the primary tumor size and extent (pT), the external irradiation dosage and the degree of TSH suppression proved to be

    To compare survival outcomes for two fractionation schedules of thoracic radiotherapy, both given over 3 weeks, in patients with limited stage small cell lung cancer (LS-SCLC). At Radiation Oncology Mater Centre (ROMC) and the Royal Brisbane and Women's Hospital (RBWH), patients with LS-SCLC treated with curative intent are given radiotherapy (with concurrent chemotherapy) to a dose of either 40Gy in 15 fractions ('the 40Gy/15⧣group') or 45Gy in 30 fractions ('the 45Gy/30⧣group'). The choice largely depends on institutional preference. Both these schedules are given over 3 weeks, using daily and twice-daily fractionation respectively. The records of all such patients treated from January 2000 to July 2009 were retrospectively reviewed and survival outcomes between the two groups compared. Of 118 eligible patients, there were 38 patients in the 40Gy/15⧣ group and 41 patients in the 45Gy/30⧣ group. The median relapse-free survival time was 12 months in both groups. Median overall survival was 21 months (95% CI 2–37 months) in the 40Gy/15⧣ group and 26 months (95% CI 1–48 months) in the 45Gy/30⧣ group. The 5-year overall survival rates were 20% and 25%, respectively (P=0.24). On multivariate analysis, factors influencing overall survival were: whether prophylactic cranial irradiation (PCI) was given (P=0.01) and whether salvage chemotherapy was given at the time of relapse (P=0.057). Given the small sample size, the potential for selection bias and the retrospective nature of our study it is not possible to draw firm conclusions regarding the efficacy of hypofractionated thoracic radiotherapy compared with hyperfractionated accelerated thoracic radiotherapy however hypofractionated radiotherapy may result in equivalent relapse-free survival.

    Extramedullary (EM) relapse of leukemia after allo-SCT in patients with AML/myelodysplastic syndrome has been increasingly reported. The reduced effectiveness of the GVL effect in EM sites, as compared with BM, has been suggested to underlie this problem. We retrospectively analyzed the pattern of relapse after haploidentical SCT (haplo-SCT), performed as the first or second SCT. Among 38 patients who received haplo-SCT as their first SCT, the cumulative incidences of BM and EM relapse at 3 years were 40.5 and 10.9%, respectively. Among 19 patients who received haplo-SCT as their second SCT, the cumulative incidences of BM and EM relapse were 30.9 and 31.9%, respectively. Moreover, most of the patients who underwent repeat haplo-SCT for the treatment of EM relapse had further EM relapse at other sites. Post-relapse survival did not differ significantly with different patterns of relapse. The frequent occurrence of EM relapse after haplo-SCT, particularly when performed as a second SCT, suggests that the potent GVL effect elicited by an HLA disparity also occurs preferentially in BM. Our findings emphasize the need for a treatment strategy for EM relapse that recognizes the reduced susceptibility of EM relapse to the GVL effect.

    Purpose: In women with favorable early breast cancer treated by lumpectomy plus tamoxifen or anastrazole, it remains unclear whether whole breast radiotherapy is beneficial. Methods and Material: Between January 1996 and June 2004, the Austrian Breast and Colorectal Cancer Study Group (ABCSG) randomly assigned 869 women to receive breast radiotherapy ± boost (n 414) or not (n = 417) after breast-conserving surgery (ABCSG Study 8A). Favorable early breast cancer was specified as tumor size <3 cm, Grading 1 or 2, negative lymph nodes, positive estrogen and/or progesterone receptor status, and manageable by breast-conserving surgery. Breast radiotherapy was performed after lumpectomy with 2 tangential opposed breast fields with mean 50 Gy, plus boost in 71% of patients with mean 10 Gy, in a median of 6 weeks. The primary endpoint was local relapse-free survival; further endpoints were contralateral breast cancer, distant metastases, and disease-free and overall survival. The median follow-up was 53.8 months. Results: The mean age was 66 years. Overall, there were 21 local relapses, with 2 relapses in the radiotherapy group (5-y rate 0.4%) vs. 19 in the no-radiotherapy group (5.1%), respectively (p = 0.0001, hazard ratio 10.2). Overall relapses occurred in 30 patients, with 7 events in the radiotherapy group (5-y rate 2.1%) vs. 23 events in the no-radiotherapy group (6.1%) (p = 0.002, hazard ratio 3.5). No significant differences were found for distant metastases and overall survival. Conclusion: Breast radiotherapy ± boost in women with favorable early breast cancer after lumpectomy combined with tamoxifen/anastrazole leads to a significant reduction in local and overall relapse

    To compare treatment and toxicity outcomes between a phase 2 institutional trial of near total neoadjuvant therapy (nTNT) for locally advanced rectal cancer and a similar historical control cohort treated at Washington University in St. Louis with the current US standard of care, defined as neoadjuvant chemoradiotherapy (NCRT), total mesorectal excision (TME), and adjuvant FOLFOX chemotherapy; to expand the comparison to an additional institution, patients treated with similar NCRT at Stanford University were included. Sixty-nine patients with cT3-4N0-2M0 rectal adenocarcinoma enrolled on the Washington University in St. Louis phase 2 study of nTNT were included for analysis. Patients treated at the same institution with conventional NCRT and adjuvant FOLFOX were matched for exact cTNM stage. Forty-one patients treated with NCRT at Stanford University were included in a second analysis. Kaplan-Meier analysis with log-rank test was used to compare local control, distant metastasis-free survival, disease-free survival, and overall survival. Median follow-up was 49 and 54 months for nTNT and NCRT, respectively. Pathologic complete response and T-downstaging rates were 28% versus 16% (P=.21) and 75% versus 41% (P<.001) in the nTNT and NCRT cohorts, respectively. Three-year disease-free survival (85% vs 68%, P=.032) was significantly better in the nTNT group. Actuarial 3-year local control (92% vs 96%, P=.36) and overall survival (96% vs 88%, P=.67) were similar. The Stanford cohort had significantly lower clinical stage. After controlling for clinical stage, age, tumor location, institution, and number of chemotherapy cycles, nTNT treatment remained significantly associated with lower risk of recurrence (P=.006). Patients treated with nTNT had higher T-downstaging and superior distant metastasis-free survival and disease-free survival compared with conventional NCRT when matched for tumor location and exact cTNM stage. Near total neoadjuvant therapy remained a

    The prognosis for children with high-risk relapsed acute lymphoblastic leukemia (ALL) is poor. Here, we assessed the prognostic importance of response during induction and consolidation treatment prior to hematopoietic stem cell transplantation (HSCT) aiming to evaluate the best time to assess minimal residual disease (MRD) for intervention strategies and in future trials in high-risk ALL relapse patients. Included patients (n=125) were treated uniformly according to the ALL-REZ BFM (Berlin-Frankfurt-Münster) 2002 relapse trial (median follow-up time=4.8 years). Patients with MRD ⩾10(-3) after induction treatment (76/119, 64%) or immediately preceding HSCT (19/71, 27%) had a significantly worse probability of disease-free survival 10 years after relapse treatment begin, with 26% (±6%) or 23% (±7%), respectively, compared with 58% (±8%) or 48% (±7%) for patients with MRD treatment reduced MRD to treatment can be used to quantify the activity of different induction treatment strategies in phase II trials. MRD persistence at ⩾10(-3) before HSCT reflects a disease highly resistant to conventional intensive chemotherapy and requiring prospective controlled investigation of new treatment strategies and drugs.

    Forty-two patients with stage IE ocular adnexal mucosa-associated lymphoid tissue (MALT) lymphoma were retrospectively analyzed. Five-year local control and progression-free survival rates were 100 and 77%, respectively. The most common relapsed site was the contralateral orbit. Thirty Gy of local irradiation seemed to be quite effective and safe

    Successful treatment of CNS leukemic relapse has been frustrated by frequent local recurrence and eventual marrow relapse. The authors describe the treatment of meningeal leukemia in 39 children with intrathecal remission induction followed by the placement of an Ommaya reservoir to facilitate the administration and distribution of chemotherapeutic agents into the CSF. Six hundred or 900 rad of craniospinal radiation and maintenance intraventricular and intrathecal chemotherapy was then administered. Systemic reinduction therapy was added in the later cases. Sixteen children (41%) experienced no further events, with 17+ months to 13+ years (median, 25 months) follow-up . Eleven patients (28%) had CNS recurrence, nine (23%) bone marrow (BM) relapse, and two (5%) testicular relapse as the next adverse event. The course of patients with first isolated CNS relapse differed from that of the others. Eleven (69%) of 16 patients treated for first isolated CNS relapse are alive and 9 are event free, while only 35% of patients whose CNS relapse occurred simultaneously or after recurrent disease at other sites are alive (P = .04). Seven of 23 in the later group are event free. The difference is due to the increased incidence of BM relapse in the later group (30% v 6%; P = .04). For patients with first isolated CNS relapse, the life-table median CNS remission duration is 42 months. The projected CNS relapse-free survival and event-free survival 8 to 10 years after CNS relapse are 40% and 32%, respectively. Headache, nausea, and emesis of short duration were frequent during therapy. In three patients, the reservoir had to be removed for infection. No patient suffered neurologic deficit related to the reservoir. The therapy described can reduce the CNS relapse rate with manageable toxicity

    In clinical trials of oncology drugs, overall survival (OS) is a direct measure of clinical efficacy and is considered the gold standard primary efficacy end point. The purpose of this study was to discuss the difficulties in using OS as a primary efficacy end point in the setting of evolving cancer therapies. We suggest that progression-free survival is an appropriate efficacy end point in many types of cancer, specifically those for which OS is expected to be prolonged and for which subsequent treatments are expected to affect OS.

    In an attempt to improve local control of locally advanced head and neck cancer, radiation therapy was combined with cisplatin. Forty-eight patients entered into this study. All patients were irradiated with a 60 Co unit and according to the protocol they should receive 70 Gy in the tumor area and 45 Gy in the rest of neck. Cisplatin was administered at a dose of 100 mg/m 2 on days 2, 22 and 42. Thirty-seven (80%) patients received the total radiation dose as initially planned. Thirty-four (72%) patients achieved complete and 5 (10%) partial response. Grade 3-4 toxicities included vomiting (14%) stomatitis (4%), diarrhea (2%), myelotoxicity (14%), hoarseness (4%), dysphagia (30%), weight loss (32%), nephrotoxicity (4%) and dermatitis (2%). After a median follow-up of 26 (range, 18-33) months, 16 patients have died. Among the 35 complete responders 6 later on relapsed. Median relapse-free survival has not yet been reached. Combined radiation therapy and cisplatin appears to be a highly active treatment in patients with advanced head and neck cancer as far as primary locoregional response is concerned. (orig.)

  11. Gain of chromosome arm 1q in atypical meningioma correlates with shorter progression-free survival.

    LENUS (Irish Health Repository)

    2012-02-01

    Aims: Atypical (WHO grade II) meningiomas have moderately high recurrence rates; even for completely resected tumours, approximately one-third will recur. Post-operative radiotherapy (RT) may aid local control and improve survival, but carries the risk of side effects. More accurate prediction of recurrence risk is therefore needed for patients with atypical meningioma. Previously, we used high-resolution array CGH to identify genetic variations in 47 primary atypical meningiomas and found that approximately 60% of tumors show gain of 1q at 1q25.1 and 1q25.3 to 1q32.1 and that 1q gain appeared to correlate with shorter progression-free survival. This study aimed to validate and extend these findings in an independent sample. Methods: 86 completely resected atypical meningiomas (with 25 recurrences) from two neurosurgical centres in Ireland were identified and clinical follow up was obtained. Utilizing a dual-colour interphase FISH assay, 1q gain was assessed using BAC probes directed against 1q25.1 and 1q32.1. Results: The results confirm the high prevalence of 1q gain at these loci in atypical meningiomas. We further show that gain at 1q32.1 and age each correlate with progression-free survival in patients who have undergone complete surgical resection of atypical meningiomas. Conclusions: These independent findings suggest that assessment of 1q copy number status can add clinically useful information for the management of patients with atypical meningiomas.

    Purpose: We present an update analysis of the multiinstitutional Ewing's sarcoma study CESS 86. Methods and Materials: From January 1986 through June 1991, 177 patients with localized Ewing's sarcoma of bone, aged 25 years or less, were recruited. Chemotherapy consisted of four 9-week courses of vincristine, actinomycin D, cyclophosphamide, and adriamycin (VACA) in low-risk tumors (extremity tumors 3 ), or vincristine, actinomycin D, ifosfamide, and adriamycin (VAIA) in high-risk tumors (central tumors and extremity tumors ≥ 100 cm 3 ). Local therapy was an individual decision in each patient and was either radical surgery (amputation, wide resection) or resection plus postoperative irradiation with 45 Gy or definitive radiotherapy with 60 Gy (45 Gy plus boost). Irradiated patients were randomized concerning the type of fractionation in either conventional fractionation (once daily 1.8-2.0 Gy, break of chemotherapy) or hyperfractionated split-course irradiation simultaneously with the VACA/VAIA chemotherapy (twice daily 1.6 Gy, break of 12 days after 22.4 Gy and 44.8 Gy, total dose and treatment time as for conventional fractionation). For quality assurance in radiotherapy, a central treatment planning program was part of the protocol. Results: Forty-four patients (25%) received definitive radiotherapy; 39 (22%) had surgery, and 93 (53%) had resection plus postoperative irradiation. The overall 5-year survival was 69%. Thirty-one percent of the patients relapsed, 30% after radiotherapy, 26% after radical surgery, and 34% after combined local treatment. The better local control after radical surgery (100%) and resection plus radiotherapy (95%) as compared to definitive radiotherapy (86%) was not associated with an improvement in relapse-free or overall survival because of a higher frequency of distant metastases after surgery (26% vs. 29% vs. 16%). In irradiated patients, hyperfractionated split-course irradiation and conventional fractionation yielded the same

    2018-01-01

    Full Text Available Acute lymphoblastic leukemia is commonly cured when diagnosed in the pediatric population. It portends a poorer prognosis if present in adult patients. Although adults frequently achieve complete remission, relapse rates are substantial, particularly among the elderly and high-risk populations. In the absence of prophylactic intrathecal chemotherapy, more than half of patients may develop CNS involvement or relapse, which is associated with significant risk for systemic illness. This report describes a patient with acute lymphoblastic leukemia with repeated isolated CNS relapses. This case should remind clinicians that isolated CNS disease in the absence of systemic recurrence could successfully respond to intrathecal therapy and offer patients a favorable quality of life.

    Background and purpose: Orbital non-Hodgkin's lymphomas (NHL) have traditionally been treated with radiation. Forty-eight patients presenting with orbital NHL were treated with radiation and were evaluated for local control, overall survival, cause-specific survival, and complications. Materials and methods: Forty-five patients had low-grade and 3 patients had intermediate-grade histologic findings. Orbit-only disease occurred in 22 patients, the conjunctiva in 16, both in five, and lacrimal gland only in five. Patient age ranged from 35 to 94 years (median, 68). Ann Arbor stages were cIEA (34), cIIEA (six), cIIIEA (two), and cIVEA (six). Radiation doses ranged between 15 and 53.8 Gy (median, 27.5 Gy). Results: Follow-up ranged from 0.14 to 18.23 years (median, 5.35). Median overall survival and cause-specific survival were 6.5 and 15.5 years, respectively. Patients with clinical stage I or II disease had significantly better overall and cause-specific survival than patients with stage III or IV disease. Ten-year relapse-free survival in 41 patients with stage I or II disease was 66%. However, there was continued downward pressure on relapse-free survival out to 18 years. One local failure occurred. Twenty-five patients sustained acute complications. There were 17 minor and four major late complications. All major late complications occurred with doses more than 35 Gy. Conclusions: Excellent local control with radiation doses ranging from 15 to 30 Gy is achieved. Patients with stage I or II disease have better overall and cause-specific survival than patients with stage III or IV disease. Late relapse occurs in sites other than the treated orbit, even in patients with early-stage disease. Doses 35 Gy or higher result in significant late complications and are therefore not indicated for patients with low-grade tumors

    Bone marrow was recently proposed as an alternative and potentially immune-privileged site for pancreatic islet transplantation. The aim of the present study was to assess the survival and rejection mechanisms of free and encapsulated xenogeneic islets transplanted into the medullary cavity of the femur, or under the kidney capsule of streptozotocin-induced diabetic C57BL/6 mice. The median survival of free rat islets transplanted into the bone marrow or under the kidney capsule was 9 and 14 days, respectively, whereas that of free human islets was shorter, 7 days (bone marrow) and 10 days (kidney capsule). Infiltrating CD8+ T cells and redistributed CD4+ T cells, and macrophages were detected around the transplanted islets in bone sections. Recipient mouse splenocytes proliferated in response to donor rat stimulator cells. One month after transplantation under both kidney capsule or into bone marrow, encapsulated rat islets had induced a similar degree of fibrotic reaction and still contained insulin positive cells. In conclusion, we successfully established a small animal model for xenogeneic islet transplantation into the bone marrow. The rejection of xenogeneic islets was associated with local and systemic T cell responses and macrophage recruitment. Although there was no evidence for immune-privilege, the bone marrow may represent a feasible site for encapsulated xenogeneic islet transplantation. PMID:24625569

    Full Text Available Abstract Background Family psychoeducation is a relatively simple and straightforward intervention whose prophylactic effectiveness and cost-effectiveness is well-established for schizophrenia. We have recently demonstrated its effectiveness for unipolar depression, but its cost-effectiveness has never been examined. We hereby report a cost-effectiveness analysis alongside a randomized controlled trial in order to assess its cost-effectiveness for preventing relapse/recurrence in depression. Methods Fifty-seven patients diagnosed with major depression and undergoing its maintenance treatment, and their primary family members were randomized to treatment as usual (TAU only or to TAU plus family psychoeducation, which consisted of four 2-hour multiple-family sessions consisting of didactic lectures about depression (30 minutes and group discussion and problem solving (60–90 minutes. The economic analyses were undertaken from the perspective of the National Health Insurance (NHI, assuming the most reasonable price of US$50 per psychoeducation session per patient. The main outcome measures included relapse-free days and direct costs to the NHI. Results The intervention group enjoyed 272 (SD: 7.1 relapse-free days, while the control group spent 214 (SD: 90.8 relapse-free days (Cox proportional hazard ratio = 0.17, 95%CI: 0.04 to 0.75, p = 0.002. Cost-effectiveness acceptability curves suggested that the family psychoeducation has 90% or more chances of being cost-effective if the decision-maker is prepared to pay US$20 for one additional relapse-free day. This cost-effectiveness finding was robust when the price for family psychoeducation ranged between 50% to 150% of the baseline scenario in sensitivity analyses. If a relapse-free day is considered to be worth $30 or more, all the pricing scenarios have a close to 100% probability of being cost-effective. Conclusion Family psychoeducation is effective in the relapse prevention of

    As a haemostatic irradiation is often proposed to patients suffering from a primitive bladder cancer, the authors report a retrospective mono-centric analysis of the effects of an external bi-dimensional palliative radiotherapy on patients taken into care for relapsing macroscopic hematuria after failure of local urological treatments. The assessment concerns the hematuria persistence, the interval without hematuric relapse, global survival, and transfusion needs. Based on a sample of 21 patients submitted to different irradiation schemes, the authors notice that a simple pelvic irradiation technique results in a fast symptomatic improvement of hematuria among fragile patients.

    Acute myeloid leukemia (AML) is the most frequent type of acute leukemia in adults. Despite recent advances in the characterization of pathogenesis of AML, the cure rates are under 40%, being leukemia relapse the most common cause of treatment failure. Leukaemia relapse occurs due to clonal evolution or clonal escape. In this study, we aimed to analyze the clinical and biological factors influencing outcomes in patients with AML relapse. We included a total of 75 AML patients who experienced leukaemia relapse after achieving complete remission. We performed complete immunophenotyping and conventional karyotyping in bone marrow aspirates obtained at diagnosis and at leukemia relapse. Overall survival (OS) of the series was 3.7%±2.3, leukaemia progression being the most common cause of death. Patients relapsing before 12 months and those with adverse cytogenetic-molecular risk had statistically significant worse outcomes. A percentage of 52.5 of patients showed phenotypic changes and 50% cytogenetic changes at relapse. We did not find significant clinical factors predicting clonal evolution. The presence of clonal evolution at relapse did not have a significant impact on outcome. Patients with relapsed AML have a dismal prognosis, especially those with early relapse and adverse cytogenetic-molecular risk. Clonal evolution with phenotypic and cytogenetic changes occurred in half of the patients without predictive clinical factors or impact on outcome. Copyright © 2016 Elsevier España, S.L.U.

    Salvage reinduction therapy followed by high-dose chemotherapy (HDCT) and auto-SCT is the treatment of choice for fit patients with refractory or relapsed aggressive non-Hodgkin's lymphoma (NHL). We assessed the prognostic value of comorbidity at the time of relapse to predict receipt of auto-SCT and outcome. We analyzed 156 consecutive NHL patients, referred to our center between 1999 and 2007 for salvage reinduction therapy, followed by HDCT and auto-SCT. Comorbidity according to the hematopoietic SCT comorbidity index was scored at relapse and directly before HDCT and auto-SCT. Primary end points were actual receipt of auto-SCT and survival. At relapse, comorbidity scores of 0, 1-2 and ≥3 were found among 64 (41%), 62 (40%) and 30 (19%) patients, respectively. Ultimately, 95 patients received auto-SCT. Higher comorbidity scores at relapse were associated with significantly less chance of receiving auto-SCT and with inferior OS, independently from secondary age-adjusted International Prognostic Index (sAAIPI) scores. For transplanted patients, OS rates at 5 years were 62, 30 and 17% for relapse comorbidity scores of 0, 1-2 and ≥3, respectively. In patients with relapsed NHL, comorbidity at relapse is associated with receipt of auto-SCT and subsequent survival independently from the sAAIPI.

    To clarify the role of external-beam radiotherapy in the local management of state IVB esophageal cancer. We reviewed records of 31 patients with histopathologically-proven squamous cell carcinoma who underwent radiotherapy for their primary lesion. The change in dysphagia score from before to after treatment was assessed. Nutritional support-free survival (NSFS) was also evaluated. The median overall survival was 6 months. The overall rate of improvement in dysphagia score was 73% (23/31). The median NSFS was 5 months. Age at presentation esophageal cancer is an effective treatment option for dysphagia. Factors highly associated with improvement of swallowing are age, tumor location, and tumor length. Response to radiotherapy is the most important factor in improving NSFS.

The disease subtypes are recognized extranodal, nodal, and splenic MZLs. The disease characteristics, clinical course, and treatment vary considerably based on the site of involvement. In 2017, the US Food and Drug Administration approved ibrutinib, a first in class Bruton’s tyrosine kinase inhibitor that revolutionized the care of chronic lymphocytic leukemia patients; for, the treatment of relapsed/refractory MZL based on pivotal open-label Phase II trial demonstrated an overall response rate of 48%, with a complete response rate of 3%, median progression-free survival of 14.2 months, and median overall survival not yet reached at a median follow-up of 19.4 months. In this review, we aim to summarize the current conundrums in the management of MZL and the evolving role of ibrutinib in the treatment of MZL.

    2010-01-01

    Purpose: To assess the effect of radiotherapy (RT) dose and volume on relapse patterns in patients with Stage I-III Merkel cell carcinoma (MCC). Patients and Methods: This was a retrospective analysis of 112 patients diagnosed with MCC between January 2000 and December 2005 and treated with curative-intent RT. Results: Of the 112 evaluable patients, 88% had RT to the site of primary disease for gross (11%) or subclinical (78%) disease. Eighty-nine percent of patients had RT to the regional lymph nodes; in most cases (71%) this was for subclinical disease in the adjuvant or elective setting, whereas 21 patients (19%) were treated with RT to gross nodal disease. With a median follow-up of 3.7 years, the 2-year and 5-year overall survival rates were 72% and 53%, respectively, and the 2-year locoregional control rate was 75%. The in-field relapse rate was 3% for primary disease, and relapse was significantly lower for patients receiving ≥50Gy (hazard ratio [HR] = 0.22; 95% confidence interval [CI], 0.06-0.86). Surgical margins did not affect the local relapse rate. The in-field relapse rate was 11% for RT to the nodes, with dose being significant for nodal gross disease (HR = 0.24; 95% CI, 0.07-0.87). Patients who did not receive elective nodal RT had a much higher rate of nodal relapse compared with those who did (HR = 6.03; 95% CI, 1.34-27.10). Conclusion: This study indicates a dose-response for subclinical and gross MCC. Doses of ≥50Gy for subclinical disease and ≥55Gy for gross disease should be considered. The draining nodal basin should be treated in all patients.

    Many efforts have been made to detect local relapse (LR) in the follow-up after stereotactic body radiotherapy (SBRT) for non-small-cell lung cancer (NSCLC) although limited data are available on its treatment and prognosis. We aimed to characterize treatment options and clarify long-term outcomes of isolated LR after SBRT for patients with clinical stage I NSCLC. We reviewed our institutional database in search of patients with isolated LR after SBRT for clinical stage I NSCLC at our institution between 1999 and 2013. Patient characteristics were compared with Mann-Whitney U test, χ2 test, or Fisher's exact test as appropriate. Survival outcomes were estimated with Kaplan-Meier method. Potential prognostic factors were investigated using Cox proportional hazard model. Of 308 patients undergoing SBRT for clinical stage I NSCLC, 49 patients were identified to have isolated LR. Twelve patients underwent salvage surgery, none underwent radiotherapy, and eight patients received chemotherapy, whereas 29 patients received best supportive care. No patient characteristic except operability was significantly related with patient selection for LR treatments. Five-year overall survival (OS) rate of the whole cohort was 47.9% from SBRT and 25.7% from LR. Salvage surgery was associated with improved OS after LR (p = 0.014), and 5-year OS for patients undergoing salvage surgery was 79.5% from LR. It was confirmed that our patient selection for salvage surgery for isolated LR was associated with favorable survival outcomes. Operability based on multidisciplinary conferences, rather than measurable patient characteristics, is essential for appropriate patient selection for salvage surgery.

    In 2005, SenterNovem, the Dutch Broadcasting Corporation, a publishing company and a consortium of local authorities launched 'Energy Survival'; a renewing energy marketing strategy for children to create a demand for local energy actions. New elements are powerful branding and the use of cross media techniques through national TV, internet, local events and primary education. Through entertainment, Energy Survival influences children's attitude towards energy consumption and its convincing relation with the environment. It aims at qualifying children to become 'energy ambassadors' in their own local environment: family, school and neighbourhood. Energy Survival has become a well tested energy game-concept for children in whom public and private partners cooperate under one brand name and with a clear division of roles and interests. However, the backbone of the concept is the local approach: local actions in municipalities and in primary schools, supported by television and internet where children learn to deal with the upcoming energy challenges of the planet they will inherit. By providing an internet-based teaching method, especially primary schools will be an effective multiplier to reach children. Broadcasting the energy game on national TV on the one hand, and local events and preliminaries on the other hand, ensure opportunities for widespread 'duplication' of the concept, adapted to local policy priorities regarding sustainable energy because each municipality is permitted to choose its own themes. Despite the fact that the project is still young and that the partners consider it as a 'long term-investment', the first independent monitoring results indicate that Energy Survival so far is quite successful. Ratings of the first TV-series show a national market share of 20 % in the age group 6-12 years and significantly more interaction between children and their parents on energy related issues.

    To determine factors associated with smoking relapse in men who survived from their first stroke. Data were collected through face to face interviews with stroke patients in the hospital, and then repeated every three months via telephone over the period from 2010 to 2014. Kaplan-Meier method and competing risk model were adopted to estimate and predict smoking relapse rates. The Kaplan-Meier method estimated a higher relapse rate than the competing risk model. The four-year relapse rate was 43.1% after adjustment of competing risk. Exposure to environmental tobacco smoking outside of home and workplace (such as bars and restaurants) ( P =0.01), single ( P <0.01), and prior history of smoking at least 20 cigarettes per day ( P =0.02) were significant predictors of smoking relapse. When competing risks exist, competing risks model should be used in data analyses. Smoking interventions should give priorities to those without a spouse and those with a heavy smoking history. Smoking ban in public settings can reduce smoking relapse in stroke patients.

    Background: Short course chemotherapy followed by radiotherapy is a standard treatment for early Hodgkin's disease. There is yet no consensus regarding the appropriate radiotherapy portal following chemotherapy. A good guide to the adjuvant radiotherapy field is the site of relapse in patients treated with chemotherapy alone. Patients and methods: From 1980 to 1996, 61 patients with stage I and II supradiaphragmatic Hodgkin's disease were treated with chemotherapy alone at the Royal Marsden Hospital. We undertook a retrospective review and failure analysis to define the pattern of recurrence. Results: After a median follow-up of 6.5 years, 24 patients had relapsed giving a 5-year relapse rate of 40%. The 5 and 10-year actuarial survival rates were 94 and 89%, respectively with cause-sepecific survival being 94% at 5 and 10 years. Two-thirds of the relapses were nodal and supradiaphragmatic. Twenty patients (83%) relapsed in the initially involved sites of disease and this was the sole site of recurrence in 11 (45%) of patients. In retrospect, it appeared that at least 12 recurrences could have been prevented by involved field radiotherapy. Review of detailed imaging data (available in 9 out of 11 patients with recurrences in initial sites of disease) showed that the relapses were always in the initially involved nodes. Conclusion: After chemotherapy alone in early stage HD most initial recurrences are nodal. Loco-regional recurrences are in the originally involved nodes. Based on limited data it appears that involved nodal RT is equivalent to involved field radiotherapy and may halve the risk of recurrence

    Purpose: To analyze retrospectively the long-term results of external beam radiotherapy (RT) with or without intraluminal brachytherapy (ILBT) for patients with Stage I esophageal cancer. Methods and Materials: A total of 34 patients with esophageal squamous cell carcinoma, clinically diagnosed as having Stage I disease, were treated with definitive RT, with or without ILBT. The median age was 69 years. Seven patients were treated with external beam RT alone (median, 64 Gy), and 27 were treated with external beam RT (median, 52 Gy) plus ILBT (8-12 Gy in two to three fractions). Results: The 5-year overall survival, local relapse-free survival, and cause-specific survival rate was 58.9%, 68.4%, and 80.0%, respectively, with a median follow-up of 61 months. Of 9 patients with local recurrence after initial therapy, 7 were successfully treated, and the 5-year cumulative rate of esophagectomy was 19.6%. The 2-year local relapse-free rate for patients with and without ILBT was 79.1% and 53.6%, respectively. Conclusion: Although local recurrence was frequent within 2 years, the disease-specific survival rate was high owing to effective salvage therapy. Definitive RT is a reasonable treatment option for highly comorbid and elderly patients with Stage I esophageal cancer. The role of ILBT needs to be clarified

    Here, we describe the case of a patient diagnosed with locally advanced breast cancer 8 years ago. Her treatment course was neoadjuvant chemotherapy, followed by mastectomy and then adjuvant radiotherapy and trastuzumab (TTZ). During the use of adjuvant targeted therapy, an incidental pregnancy was diagnosed. Four years later, she developed bone and cerebral metastases, and since then, she has received courses of TTZ, capecitabine, lapatinib, and radiotherapy with intermittent control of the disease. Her 7-year-old son presents a normal physical and long-term neurological developmental curve according to specialized evaluation. This case is unique for several reasons: the patient received the highest dose of TTZ yet described during pregnancy (4400 mg); there has been a long period of disease-free survival after treatment for locally advanced breast cancer and long overall survival despite successive disease progressions during the metastatic phase of the disease (97 months), and there was a monitored pediatric follow-up period (7 years).

    Full Text Available Breast cancer in young women tends to have a natural history of aggressive disease for which rates of recurrence are higher than in breast cancers detected later in life. Little is known about the genetic pathways that underlie early-onset breast cancer. Here we report the discovery of DEAR1 (ductal epithelium-associated RING Chromosome 1, a novel gene encoding a member of the TRIM (tripartite motif subfamily of RING finger proteins, and provide evidence for its role as a dominant regulator of acinar morphogenesis in the mammary gland and as an independent predictor of local recurrence-free survival in early-onset breast cancer.Suppression subtractive hybridization identified DEAR1 as a novel gene mapping to a region of high-frequency loss of heterozygosity (LOH in a number of histologically diverse human cancers within Chromosome 1p35.1. In the breast epithelium, DEAR1 expression is limited to the ductal and glandular epithelium and is down-regulated in transition to ductal carcinoma in situ (DCIS, an early histologic stage in breast tumorigenesis. DEAR1 missense mutations and homozygous deletion (HD were discovered in breast cancer cell lines and tumor samples. Introduction of the DEAR1 wild type and not the missense mutant alleles to complement a mutation in a breast cancer cell line, derived from a 36-year-old female with invasive breast cancer, initiated acinar morphogenesis in three-dimensional (3D basement membrane culture and restored tissue architecture reminiscent of normal acinar structures in the mammary gland in vivo. Stable knockdown of DEAR1 in immortalized human mammary epithelial cells (HMECs recapitulated the growth in 3D culture of breast cancer cell lines containing mutated DEAR1, in that shDEAR1 clones demonstrated disruption of tissue architecture, loss of apical basal polarity, diffuse apoptosis, and failure of lumen formation. Furthermore, immunohistochemical staining of a tissue microarray from a cohort of 123 young

    Purpose: To discuss the results obtained by giving adjuvant treatment for childhood ependymoma (EPD) at relapse after complete surgery only. Methods and Materials: Between 1993 and 2002, 63 children older than 3 years old entered the first Italian Association for Pediatric Hematology and Oncology protocol for EPD (group A), and another 14 patients were referred after relapsing after more tumor excisions only (group B). Prognostic factors were homogeneously matched in the two groups. We report on the outcome of group B. Results: Mean time to first local progression in group B had been 14 months. Tumors originated in the posterior fossa (PF) in 10 children and were supratentorial (ST) in 4; 11 had first been completely excised (NED) and 3 had residual disease (ED). Diagnoses were classic EPD in 9 patients, anaplastic in 5. Eight children were referred NED and 6 ED after two or more operations, 5 had cranial nerve palsy, 1 had recurrent meningitis, and 2 had persistent hydrocephalus. All received radiotherapy (RT) to tumor bed and 5 also had pre-RT chemotherapy. Six of 14 patients (6/10 with PF tumors) had a further relapse a mean 6 months after the last surgery; 4 of 6 died: progression-free survival and overall survival at 4 years after referral were 54.4% and 77%, respectively. Considering only PF tumors and setting time 0 as at the last surgery for group B, progression-free survival and overall survival were 32% and 50% for group B and 52% (p < 0.20)/70% (p < 0.29) for the 46 patients in group A with PF tumors. Local control was 32% in group B and 70.5% in group A (p = 0.02). Conclusions: Relapsers after surgery only, especially if with PF-EPD, do worse than those treated after first diagnosis; subsequent surgery for tumor relapse has severe neurologic sequelae

    1998-01-01

    Purpose: This prospective randomized trial in extensive untreated Hodgkin's disease was undertaken to assess the potential benefit of augmented therapy (12 months chemotherapy or radiation to known disease) compared to standard 6 months chemotherapy. Patient and Methods: A total of 258 patients, mostly Stage IV, were randomized to four treatment regimens consisting of six cycles of CCNU, vinblastine, procarbazine, and prednisone (CVPP); 12 cycles of CVPP; six cycles of CVPP followed by 25 Gy radiotherapy; or three cycles CVPP, 25 Gy radiotherapy, and three cycles CVPP. Results: Complete remissions were achieved in 65% of all patients. A 58% overall 5-year survival rate was obtained. Relapses in irradiated areas of known disease occurred in only 6% of responding patients. There was, however, no statistical difference in response frequency, disease-free survival, or overall survival among the four regimens. Elderly patients responded less frequently. Conclusion: While radiotherapy provided control of local (known) disease, no impact on overall survival was apparent. Likewise, doubling the duration of chemotherapy did not improve response or survival. Augmentation of therapy with either radiotherapy or more chemotherapy in this study was of no benefit compared to the standard 6 months of treatment

    Purpose: There is evidence that computed tomography (CT) and positron emission tomography (PET) imaging metrics are prognostic and predictive in nonsmall cell lung cancer (NSCLC) treatment outcomes. However, few studies have explored the use of standardized uptake value (SUV)-based image features of nodal regions as predictive features. The authors investigated and compared the use of tumor and node image features extracted from the radiotherapy target volumes to predict relapse in a cohort of NSCLC patients undergoing chemoradiation treatment. Methods: A prospective cohort of 25 patients with locally advanced NSCLC underwent 4DPET/4DCT imaging for radiation planning. Thirty-seven image features were derived from the CT-defined volumes and SUVs of the PET image from both the tumor and nodal target regions. The machine learning methods of logistic regression and repeated stratified five-fold cross-validation (CV) were used to predict local and overall relapses in 2 yr. The authors used well-known feature selection methods (Spearman’s rank correlation, recursive feature elimination) within each fold of CV. Classifiers were ranked on their Matthew’s correlation coefficient (MCC) after CV. Area under the curve, sensitivity, and specificity values are also presented. Results: For predicting local relapse, the best classifier found had a mean MCC of 0.07 and was composed of eight tumor features. For predicting overall relapse, the best classifier found had a mean MCC of 0.29 and was composed of a single feature: the volume greater than 0.5 times the maximum SUV (N). Conclusions: The best classifier for predicting local relapse had only tumor features. In contrast, the best classifier for predicting overall relapse included a node feature. Overall, the methods showed that nodes add value in predicting overall relapse but not local relapse.

    Multi-modality treatment consisting of cisplatin, VP-16, and 5-fluorouracil chemotherapy given concomitantly with external beam radiation was used to treat 64 patients with locally advanced Stage III non-small cell lung carcinoma. This regimen was used in a preoperative fashion for four cycles in patients considered surgically resectable and with curative intent for six cycles in the remainder of patients. The clinical response rate for the entire group was 84% and the overall local control rate was 74%. The median survival was 13 months with a median follow-up for live patients of 19 months. The actuarial 3-year survival and disease-free survival rates were 30% and 23%, respectively. Histologic complete response was 39% and appeared to predict for survival. The 3-year actuarial survival and disease-free survival rates for 23 resected patients were 69% and 45%, respectively, with the complete histologic responders having a disease-free survival of 78%. The pattern of first recurrence did not appear to differ by histology or presence of lymph nodes in this subset of patients. The actuarial 3-year survival and disease-free survival rates for inoperable patients receiving six cycles of treatment were 18% and 23%, respectively. The local control was 67% with the majority of these patients having Stage IIIB disease. The Mountain International staging system appeared to predict for operability, local recurrence, and survival. This concomitant treatment regimen is feasible, with the major toxicities being leukopenia, nausea, and vomiting

    Primary or neoadjuvant chemotherapy prior to definitive local therapy has potential advantages for locally advanced cervix cancer. It can down stage a cancer and allow definitive local therapy to be technically possible (surgery), or potentially more effective (radiotherapy). It can also eradicate subclinical systemic metastases. This report reviews a single institution's experience of neoadjuvant chemotherapy prior to definitive local therapy for cervix cancer over a 13-year period. One hundred and six patients were treated with this intent. The patients were analysed for their response to chemotherapy, treatment received, survival, relapse and toxicity. The chemotherapy was feasible and the majority of patients had a complete or partial response (58.5%). Eight patients did not proceed to local treatment. Forty-six patients had definitive surgery and 52 had definitive radiotherapy. The 5-year overall survival was 27% and the majority of patients died with disease. The first site of relapse was usually in the pelvis (46.2%). Late complications that required ongoing medical therapy (n = 6) or surgical intervention (n = 2) were recorded in eight patients (7.5%). On univariate analysis stage (P= 0.04), tumour size (P = 0.01), lymph node status (P=0.003), response to chemotherapy (P = 0.045) and treatment (P = 0.003) were all significant predictors of survival. On multivariate analysis, tumour size (P < 0.0001) and nodal status (P = 0.02) were significant predictors of survival. Despite the impressive responses to chemotherapy of advanced cervix cancer, there is evidence from randomized trials that it does not improve or compromise survival prior to radiotherapy. As its role prior to surgery remains unclear, it should not be used in this setting outside a prospective randomized trial. Copyright (2001) Blackwell Science Pty Ltd

    Introduction: Recent studies have renewed an old controversy about the efficacy of adjuvant radiotherapy following mastectomy for breast cancer. Radiotherapy is usually recommended for advanced disease, but whether or not to use it in pT1-T2 pN0 situations is still being debated. This study was designed to clarify whether or not routine radiotherapy of the chest wall following mastectomy reduces the risk of local recurrence and if it influences the overall survival rate. Methods: Retrospective analysis of patients treated with mastectomy for pT1-T2 pN0 tumors and no systemic treatment. Patients treated with radiotherapy of the chest wall following mastectomy (Group A) are compared with those treated with mastectomy alone (Group B). Results: A total of 918 patients underwent mastectomy. Patients who received adjuvant radiotherapy after mastectomy (n = 114) had a significantly lower risk for local recurrence. Ten years after the primary diagnosis, 98.1% of the patients with radiotherapy were disease free compared to 86.4% of the patients without radiotherapy. The average time interval from primary diagnosis until local recurrence was 8.9 years in Group A and 2.8 years in Group B. The Cox regression analysis including radiotherapy, tumor size and tumor grading found the highest risk for local recurrence for patients without radiotherapy (p < 0.0004). In terms of overall survival however, the Kaplan-Meier analysis showed no difference between the two groups (p = 0.8787) and the Cox regression analysis failed to show any impact on overall survival. Conclusion: With observation spanning over 35 years, this study shows that adjuvant radiotherapy of the chest wall following mastectomy reduces the risk for local recurrence in node-negative patients with pT1-T2 tumors but has no impact on the overall survival rate

    The authors report a retrospective study which aimed at assessing the use of a concomitant chemo-radiotherapy, its tolerance and its feasibility in the case of a locally advanced rectum cancer. Based on data obtained among 62 patients presenting a rectum cancer, they analyse the results in terms of tolerance (cases of leukopenia, anemia, diarrhea, radiodermatitis), of relapses, and survival. Toxicity is acceptable and the concomitant treatment renders the tumour operable in many cases. Short communication

    Purpose: To examine the costs and benefits of an established practice of routine follow-up in a cohort of patients treated with radiation therapy for early stage Hodgkin's disease. Materials and Methods: We retrospectively examined patterns of follow-up and methods of relapse detection among 709 patients with Ann Arbor Stage I-II Hodgkin's disease treated with sub-total lymphoid irradiation (STLI) or total lymphoid irradiation (TLI) between 1969-1994. We determined the probability of relapse detection for each of 7 routine follow up procedures, compared their relative costs, and determined the impact of each procedure on the likelihood of overall survival following salvage therapy. Results: Relapse has occurred in 157 patients (22%) at a median 1.9 years (range 0-13 years) following treatment. 133 relapses (85%) occurred during the first 5 years of follow. Detailed information concerning the method of relapse detection was available on 107 patients. These 107 patients form the basis of this analysis. Relapse was identified by history (Hx) alone in 55% of patients, physical exam (PE) in 14%, chest x-ray (CXR) in 23% and abdominal x-ray (KUB) in 7%. Only one relapse (1%) was identified by a routine laboratory study - erythrocyte sedimentation rate (ESR). The rate of relapse detection was highest for a combination of history and physical exam (78/10,000 exams) followed by CXR (26/10,000 exams), KUB (10/10,000 exams) and ESR (1/10,000 tests). Complete blood count (CBC) and serum chemistries were never the primary factor in detecting HD relapse. Radiographs accounted for greater than 60% of charges while laboratory studies and physician charges accounted for approximately 20% each. The projected charges (1994 dollars) of relapse detection by routine follow up Hx and PE was [dollar]10,600 compared with [dollar]68,200 for CXR, [dollar]141,800 for KUB and [dollar]156,400 for ESR. 10 year actuarial survival following salvage therapy was 65% overall, 65% for patients in whom

    Background: Pregnancy-associated nasopharyngeal carcinoma (PANPC) has been associated with poor survival. Recent advances in radiation technology and imaging techniques, and the introduction of chemotherapy have improved survival in nasopharyngeal carcinoma (NPC); however, it is not clear whether these changes have improved survival in PANPC. Therefore, the purpose of this study was to compare five-year maternal survival in patients with PANPC and non-pregnant patients with NPC. Methods: After adjusting for age, stage and chemotherapy mode, we conducted a retrospective case-control study among 36 non-metastatic PANPC patients and 36 non-pregnant NPC patients (control group) who were treated at our institution between 2000 and 2010. Results: The median age of both groups was 30 years (range, 23–35 years); median follow-up for all patients was 70 months. Locoregionally-advanced disease accounted for 83.3% of all patients with PANPC and 92.9% of patients who developed NPC during pregnancy. In both the PANPC and control groups, 31 patients (86.1%) received chemotherapy and all patients received definitive radiotherapy. The five-year rates for overall survival (70% vs. 78%, p = 0.72), distant metastasis-free survival (79% vs. 76%, p = 0.77), loco-regional relapse-free survival (97% vs. 91%, p = 0.69) and disease-free survival (69% vs. 74%, p = 0.98) were not significantly different between the PANPC and control groups. Multivariate analysis using a Cox proportional hazards model revealed that only N-classification was significantly associated with five-year OS. Conclusion: This study demonstrates that, in the modern treatment era, pregnancy itself may not negatively influence survival outcomes in patients with NPC; however, pregnancy may delay the diagnosis of NPC

    Relapsed/refractory acute lymphoblastic leukemia (ALL) has a low remission rate after chemotherapy, a high relapse rate and poor long-term survival even when allogeneic hematopoietic stem cell transplantation (allo-HSCT) is performed. Chimeric antigen receptors redirected T cells (CAR-T cells) can enhance disease remission with a favorable outcome for relapsed/refractory ALL, though some cases quickly relapsed after CAR-T cell treatment. Thus, treatment with CAR-T cells followed by allo-HSCT may be the best way to treat relapsed/refractory ALL. In this review, we first discuss the different types of CAR-T cells. We then discuss the treatment of relapsed/refractory ALL using only CAR-T cells. Finally, we discuss the use of CAR-T cells, followed by allo-HSCT, for the treatment of relapsed/refractory ALL.

    Full Text Available Nonprofit social service organizations in America originally relied on private donations and charitable events to sustain their operations. As the number of nonprofit organizations has proliferated over the last few decades, so has nonprofit dependency on governmental and other sources of revenue. A case study design was used to examine factors that have impacted the survival of the original Indiana Youth Service Bureaus. This study highlights salient factors that influence survival and explores the characteristics and circumstances of selected organizations that enhance their sustainability. The findings suggest that social work administrators need to foster long-term relationships with local funders as a means of enhancing organizational survival.

    Purpose/Objectives: To evaluate radiotherapy (XRT) as potential salvage treatment for patients with locally recurrent prostate cancer after redical prostatectomy (RP). Materials and Methods: Twenty-four consecutive patients with adenocarcinoma of the prostate who received definitive XRT between 1987 and 1993 for biopsy-proven (n=18) or for prostate-specific antigen (PSA) - producing (n=6) recurrent disease following RP were evaluated. No patient had clinically or radiographically evident distant disease. Biopsies of suspicious nodules or ultrasound findings in the prostatic fossa were positive in 18 and negative in 3. Three patients had no focal abnormalities and had no biopsy. The time between RP and XRT varied from 6 to 277 months (mean 52 months). XRT doses to the prostatic fossa ranged from 60 to 70 Gy (median, 66 Gy). Outcome was analyzed relative to local control, metastatic disease and PSA status. Persistently undetectable PSA was required to define freedom from disease. Results: Pre-XRT PSA levels ranged from 0.7 to 26.8 ng/ml (mean 7.3 ng/ml, median 2.5 ng/ml). Although PSA fell post-XRT in all but 3 patients and 10 (52%) achieved undetectable levels, the outcome at a median follow-up of 42 months (range 13-90 months) was poor, with 15 patients (63%) developing persistent/progressive disease. The patterns of progression in these 15 were: local 3, metastatic 3, persistent PSA 9. All patients whose PSA was persistently detectable developed a rising PSA profile. The actuarial incidence of freedom from disease at 1, 2, 3 and 4 years was 75%, 43%, 36% and 27% respectively. The only factor correlating to outcome was the pre-XRT PSA level. The 9 patients who remain free of disease had a mean PSA level of 3.6 ng/ml compared to a mean level of 9.6 ng/ml among the 15 who failed (p<0.01). All patients with a pre-XRT level >2.5 ng/ml developed disease relapse, whereas the 4-year freedom from disease in those with levels {<=}2.5 ng/ml was 52%. Eleven of the 15 patients

  9. Observer efficiency in free-localization tasks with correlated noise

    Full Text Available The efficiency of visual tasks involving localization has traditionally been evaluated using forced choice experiments that capitalize on independence across locations to simplify the performance of the ideal observer. However, developments in ideal observer analysis have shown how an ideal observer can be defined for free-localization tasks, where a target can appear anywhere in a defined search region and subjects respond by localizing the target. Since these tasks are representative of many real-world search tasks, it is of interest to evaluate the efficiency of observer performance in them. The central question of this work is whether humans are able to effectively use the information in a free-localization task relative to a similar task where target location is fixed. We use a yes-no detection task at a cued location as the reference for this comparison. Each of the tasks is evaluated using a Gaussian target profile embedded in four different Gaussian noise backgrounds having power-law noise power spectra with exponents ranging from 0 to 3. The free localization task had a square 6.7° search region. We report on two follow-up studies investigating efficiency in a detect-and-localize task, and the effect of processing the white-noise backgrounds. In the fixed-location detection task, we find average observer efficiency ranges from 35% to 59% for the different noise backgrounds. Observer efficiency improves dramatically in the tasks involving localization, ranging from 63% to 82% in the forced localization tasks and from 78% to 92% in the detect-and- localize tasks. Performance in white noise, the lowest efficiency condition, was improved by filtering to give them a power-law exponent of 2. Classification images, used to examine spatial frequency weights for the tasks, show better tuning to ideal weights in the free-localization tasks. The high absolute levels of efficiency suggest that observers are well-adapted to free-localization tasks.

    We assessed sociodemographic disparities in local 100% smoke-free laws prohibiting smoking in all indoor areas of nonhospitality worksites, restaurants, and bars in 10 states. We obtained data on local 100% smoke-free laws (US Tobacco Control Laws Database) and subcounty characteristics (2006-2010 American Community Survey) for Alabama, Alaska, Indiana, Kentucky, Mississippi, Missouri, North Dakota, South Carolina, Texas, and West Virginia. Outcomes included (1) 100% smoke-free law covering restaurants, bars, and workplaces; (2) 100% smoke-free law covering restaurants, bars, or workplaces; and (3) number of venue types covered by 100% smoke-free laws (0-3). Sociodemographics included total population, urban status, percentage racial/ethnic minority, per capita income, percentage with high-school diploma, percentage with blue-collar jobs, and percentage of workers who live and work in the same locality. Across states, localities with less-educated residents, smaller proportions of workers living and working in the same locality, or both generally had lower odds of being covered by 100% smoke-free laws. Coverage varied across states for other sociodemographics. Disparities exist in local smoke-free law coverage. Identifying patterns in coverage can inform state efforts to address related disparities.

    Purpose and objectives: To search if the pathological complete response (pCR) of the 102 patients treated at the University Hospital Center of Tours between 1990 and 2010 with concomitant radio-chemotherapy for an esophageal cancer is correlated to an increase of local control, with correct R0 resection and acceptable mortality rate. To analyze the Impact of histological tumor or nodal down-staging on the loco regional control and the disease free survival. Search if there are some predictive factors of pCR. Materials and methods: The combined preoperative treatment was based on an association of two cycles of 5FU R and cisplatin R with concomitant radiotherapy at the dose of 40 to 44 Gy. The survival curves of both recurrence free survival and disease free survival were calculated and then analyzed according to the histological response. Results: With a mean follow-up of 38 months, 70 patients were dead, 47 of their cancer. Thirty patients were still alive and 26 without recurrence. The postoperative mortality and morbidity rates were respectively of 53% and 27%. The median of survival was estimated to 27 months. Overall survival (p= 0.33), disease free survival (p= 0.14), were analysed with no statistical difference between our 3 groups (pCR, near pCR and other). However, there was an interest in doing the combined treatment for the responders (p R , Cisplatin R , and external beam radiotherapy at the dose of 40 to 44 Gy for the patients with a locally advanced esophageal cancer allow us to obtain the same results on survival, tolerance, morbidity and mortality rates than in the literature. The pCR seems to increase the local control and the disease free survival. Tumor or nodal down-staging is a major prognostic factor. (author)

    Few new compounds are available for relapsed osteosarcoma. We retrospectively evaluated the activity of gemcitabine (G) plus docetaxel (D) in patients with relapsed high-grade osteosarcoma and high-grade spindle cell sarcoma of bone (HGS). Patients receiving G 900 mg/m(2) d 1, 8; D 75 mg/m(2) d 8, every 21 days were eligible. Primary end-point: progression-free survival (PFS) at 4 months; secondary end-point: overall survival (OS) and response rate. Fifty-one patients were included, with a median age of 17 years (8-71), 26 (51%) were pediatric patients. GD line of treatment: 2nd in 14 patients, ≥3rd in 37. 25 (49%) patients had metastases limited to lungs, 26 (51%) multiple sites. 40 (78%) osteosarcoma, 11 (22%) HGS. Eight (16%) patients achieved surgical complete response (sCR2) after GD. Four-month PFS rate was 46%, and significantly better for patients with ECOG 0 (ECOG 0: 54% vs ECOG 1: 43% vs ECOG 2: 0%; p = 0.003), for patients undergoing metastasectomy after GD (sCR2 75% vs no-sCR2 40 %, p = 0.02) and for osteosarcoma (osteosarcoma 56% vs HGS 18%; p = 0.05), with no differences according to age, line of treatment, and pattern of metastases. Forty-six cases had RECIST measurable disease: 6 (13%) patients had a partial response (PR), 20 (43%) had stable disease (SD) and 20 (43%) had progressive disease (PD). The 1-year OS was 30%: 67% for PR, 54% for SD and 20% for PD (p = 0.005). GD is an active treatment for relapsed high-grade osteosarcoma, especially for ECOG 0 patients, and should be included in the therapeutic armamentarium of metastatic osteosarcoma.

    Purpose Study about the efficacy of salvage radiotherapy (R.T.), in terms of biochemical disease free survival (b.D.F.S.), according to Astro and Phoenix (nadir + 2) definitions, for persistent or rising P.S.A. after radical prostatectomy. Patients and methods Retrospective analysis of 59 patients who underwent R.T. between 1990 and 2003 for P.S.A. recurrence after radical prostatectomy. Patients received a median of 66 Gy to the prostate bed with 3D or 2D R.T.. The main end point was b.D.F.S. according to Astro and Phoenix (nadir + 2) definitions. Different criterion sets were analysed to calculate b.D.F.S. and pretreatment factors that might predict biochemical relapse were sought for each. Results After a 38-month median follow-up, the 3-year b.D.F.S. rates were: 60 and 72% for Astro and Phoenix (nadir + 2 ng/ml) definitions respectively. According to univariate analysis, pre-R.T. P.S.A. = 1 ng/ml and seminal vesicle involvement were associated with biochemical relapse. Multivariate analysis retained only pre-R.T. P.S.A. = 1 ng/ml as an independent predictor of biochemical relapse for the two definitions. Conclusion Salvage R.T. is an effective treatment after radical prostatectomy according to Astro or Phoenix definitions. Only pre-R.T. P.S.A. = 1 ng/ml predicted relapse. (authors)

    Stratifiable spaces are a natural generalization of metrizable spaces for which Dugundji's theorem holds. It is proved that the free locally convex space of a stratifiable space is stratifiable. This means, in particular, that the space of finitely supported probability measures on a stratifiable space is a retract of a locally convex space, and that each stratifiable convex subset of a locally convex space is a retract of a locally convex space

    Long-term local control in Glioblastoma is rarely achieved and nearly all patients relapse. In this study we evaluated the clinical effect of different treatment approaches in recurrent patients. Forty-three patients, with median age of 51 years were evaluated for salvage treatment: re-resection and/or re-irradiation plus chemotherapy or chemotherapy alone. Response was recorded using the Response Assessment in Neuro-Oncology criteria. Hematologic and non-hematologic toxicities were graded according to Common Terminology Criteria for Adverse Events 4.0. Twenty-one patients underwent chemotherapy combined with local treatment, surgery and/or radiation therapy, and 22 underwent chemotherapy only. The median follow up was 7 months (range 3–28 months). The 1 and 2-years Progression Free Survival was 65 and 10 % for combined treatment and 22 and 0 % for chemotherapy alone (p < 0.01). The 1 and 2-years overall survival was 69 and 29 % for combined and 26 and 0 % for chemotherapy alone (p < 0.01). No toxicity greater than grade 2 was recorded. These data showed that in glioblastoma recurrence the combination of several approaches in a limited group of patients is more effective than a single treatment alone. This stress the importance of multimodality treatment whenever clinically feasible

    Full Text Available Objective. The aim of this prospective observational multicenter postmarketing study was to evaluate fingolimod efficacy in a real world clinical setting. Methods. One hundred forty-two subjects with relapsing-remitting multiple sclerosis (RRMS were enrolled in three multiple sclerosis centers throughout Central and Southern Italy between January 2011 and September 2013. After enrollment, regular visits and EDSS assessment were scheduled every 3 months, and MRI scan was obtained every 12 months. Patients were followed up from 1 to 33 months (mean 14.95 ± 9.15 months. The main efficacy endpoints included the proportion of patients free from clinical relapses, from disability progression, from magnetic resonance imaging activity, and from any disease activity. Results. Out of 142 patients enrolled in the study, 88.1% were free from clinical relapse and 69.0% were free from disability progression; 68.5% of patients remained free from new or newly enlarging T2 lesions and 81.7% of patients were free from gadolinium enhancing lesions. Overall the proportion of patients free from any disease activity was 41.9%. Conclusions. Our data in a real world cohort are consistent with previous findings that yield convincing evidence for the efficacy of fingolimod in patients with RRMS.

    In epidemiologic studies and clinical trials with time-dependent outcome (for instance death or disease progression), survival curves are used to describe the risk of the event over time. In meta-analyses of studies reporting a survival curve, the most informative finding is a summary survival curve. In this paper, we propose a method to obtain a distribution-free summary survival curve by expanding the product-limit estimator of survival for aggregated survival data. The extension of DerSimonian and Laird's methodology for multiple outcomes is applied to account for the between-study heterogeneity. Statistics I(2)  and H(2) are used to quantify the impact of the heterogeneity in the published survival curves. A statistical test for between-strata comparison is proposed, with the aim to explore study-level factors potentially associated with survival. The performance of the proposed approach is evaluated in a simulation study. Our approach is also applied to synthesize the survival of untreated patients with hepatocellular carcinoma from aggregate data of 27 studies and synthesize the graft survival of kidney transplant recipients from individual data from six hospitals.

    To investigate the impact of hematologic toxicity and leukopenia in locally advanced cervical cancer patients undergoing neoadjuvant chemotherapy (NACT). Data of consecutive patients undergoing platinum-based NACT followed by surgery were retrospectively searched in order to evaluate the impact of chemotherapy-related toxicity on survival outcomes. Toxicity was graded per the Common Terminology Criteria for Adverse Events (CTCAEv.4.03). Survival outcomes were evaluated using Kaplan-Meir and Cox hazard models. Overall, 126 patients were included. Among those, 94 (74.6%) patients experienced grade2+ hematologic toxicity; while, grade2+ non-hematologic toxicity occurred in 11 (8.7%) patients. After a median follow-up of 37.1 (inter-quartile range, 12-57.5) months, 21 (16.6%) patients experienced recurrence. Via multivariate analysis, no factor was independently associated with disease-free survival; while a trend toward worse prognosis was observed for patients experiencing grade2+ leukopenia at cycle-3 (HR:3.13 (95%CI: 0.94, 10.3); p=0.06). Similarly, grade2+ leukopenia (HR:9.98 (95%CI: 1.14, 86.6); p=0.03), lymph-node positivity (HR:14.6 (95%CI:1.0, 214.4); p=0.05) and vaginal involvement (HR:5.81 (95%CI:1.43, 23.6); p=0.01) impacted on overall survival, at multivariate analysis. Magnitude of leukopenia correlated with survival (p<0.001). Although, our data have to be confirmed by prospective investigations, the present study shows an association between the occurrence of leukopenia and survival outcomes. NACT-related immunosuppression might reduce the response against the tumor, thus promoting cancer progression. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Background: Between 1979 and 1989, 48 cases of extradural spinal cord and cauda equina compression in patients with lymphoma (24) and myeloma (24) received local radiation therapy for control of cord compression. Twenty five (52%) of the cases were treated by surgical decompression prior to irradiation. Thirty five (73%) of the cases received chemotherapy following the diagnosis of spinal cord compression. Post-treatment outcome was assessed at a minimum follow-up of 24 months to determine the significant clinical and treatment factors following irradiation. Results: Seventeen (71%) of the lymphoma and 15 (63%) of the myeloma patients achieved local control, here defined as improvement to, or maintenance of ambulation with minimal or no assistance for 3 months from the start of radiotherapy. At a median follow-up of 30 (2-98) for the lymphoma and 10 (1-87) months for the myeloma patients, the results showed that survival following local radiation therapy for cord compression was independently influenced by the underlying disease type in favour of lymphoma compared to myeloma (P<0.01). The median duration of local control and survival figures were 23 and 48 months for the lymphomas compared to 4.5 and 10 months for the myeloma cases. Survival was also independently influenced by preservation of sphincter function at initial presentation (P<0.02) and the achievement of local control following treatment (P<0.01). Discussion: We conclude that while disease type independently impacts on outcome following treatment of spinal cord compression in lymphoma and myeloma, within both of these disease type the achievement of local control of spinal cord compression is an important management priority, for without local control survival may be adversely affected

    Full Text Available We retrospectively analyzed 14 patients with locally advanced squamous cell carcinoma of ethmoid sinus (LASCC-ES for the feasibility of anterior craniofacial resection (ACFR. Ethmoid cancer treatment comprised alternating chemoradiotherapy (ALCRT; n = 1, concomitant radiotherapy and intra-arterial cisplatin (RADPLAT; n = 4 and ACFR (n = 9. The 3- and 5-year overall survival (OS rates of patients were 47.6 and 39.6%, respectively. The 3-year local control (LC rates of chemoradiotherapy (CRT; ALCRT and RADPLAT (n = 5 and ACFR (n = 9 groups were 0 and 66.7% (p = 0.012, respectively. The 3-year progression-free survival (PFS rate of the CRT and ACFR groups were 0 and 55.6% (p = 0.018, respectively. The 3-year OS rate of the CRT and ACFR groups were 0 and 76.2% (p = 0.005, respectively. Postoperative pathological examinations confirmed positive margins in 3 (33% of 9 cases. The 3-year LC and PFS rates of cases (n = 3 with positive surgical margins were significantly poorer than those of cases (n = 6 with negative surgical margins. Although ACFR for LASCC-ES is a feasible treatment, cases with positive surgical margins were more prone to local relapse. Therefore, surgical safety margins should be thoroughly assessed.

    We investigated the factors associated with post-recurrence survival and the treatment for non-small-cell lung cancer patients with postoperative distant recurrence, especially oligometastasis. We reviewed the data of 272 patients with distant recurrence who underwent resection of non-small-cell lung cancer from January 2000 through December 2011. The type of distant recurrence was classified as oligometastasis (n = 76, 28%) or polymetastasis (n = 196, 72%). Forty-seven (62%) patients with oligometastasis received local therapy (surgery 5, radiotherapy 9, sequential local and systemic therapy 28, chemoradiotherapy 5). Multivariate analysis revealed older age, non-adenocarcinoma, shorter disease-free interval, no pulmonary metastasis, liver metastases, bone metastases, and polymetastasis had significant associations with unfavorable post-recurrence survival. Subgroup analysis of patients with oligometastasis showed histology and disease-free interval had a great impact on survival. Smoking history and histology were associated with survival in patients with lung oligometastasis, whereas systemic treatment and longer disease-free interval were related to increased post-recurrence survival in those with brain oligometastasis. This study showed that an oligometastatic state per se was a significant favorable factor. Optimization of personalized systemic treatment and adding local treatment are important in the management of patients with non-small-cell lung cancer and oligometastasis. © The Author(s) 2015.

    Central nervous system (CNS) relapse of diffuse large B-cell lymphoma (DLBCL) is a rare complication, but has a poor prognosis with unknown pathophysiology. Recent trials of CNS prophylaxis have shown to be ineffective, despite patient's selection using several known clinical risk factors. In this study, the authors evaluated the value of pretreatment [F]2-Fluoro-2-deoxyglucose positron emission tomography in predicting CNS relapse in DLBCL patients.The authors analyzed 180 pathologically confirmed DLBCL patients, retrospectively. Patients underwent [F]2-Fluoro-2-deoxyglucose positron emission tomography/computed tomography before first line rituximab to cyclophosphamide, doxorubicin, vincristine, and prednisone therapy. Clinical characteristics were evaluated and total lesion glycolysis (TLG) with a threshold margin of 50% was calculated.Among age, sex, Ann Arbor stage, International Prognostic Index, revised International Prognostic Index, high serum lactate dehydrogenase level, presence of B symptoms, bulky disease (≥10 cm), extranodal lesion involvement, bone marrow involvement, high metabolic tumor volume ( >450 mL), and high TLG50 (>2000), the high TLG50 was the only significant prognostic factor for predicting CNS relapse in a multivariate analysis (P = 0.04). Kaplan-Meir survival analysis between high TLG50 (>2000) and low TLG50 (≤2000) groups revealed significantly different mean progression free survival (PFS) of 1317.2 ± 134.3 days and 1968.6 ± 18.3 days, respectively (P positron emission tomography/computed tomography is the most significant predictor of CNS relapse in un-treated DLBCL patients.

    To evaluate the treatment outcomes of radiotherapy and prognostic factors for recurrent pancreatic cancer. The study comprised 30 patients who developed a locoregional recurrence of primarily resected pancreatic cancer and received radiotherapy between 2000 and 2013 with a median dose of 54 Gy (range, 39-60 Gy). Concurrent chemotherapy included gemcitabine for 18 patients and S-1 for seven patients. The treatment outcomes and prognostic factors were retrospectively analyzed. The median follow-up after radiotherapy was 14.6 months. The 1-year overall survival, local control, and progression-free survival rates were 69 %, 67 %, and 32 %, respectively. The median overall survival and progression-free survival rates were 15.9 and 6.9 months, respectively. Tumor marker reduction and ≥ 50 % reduction were observed in 18 and two patients, respectively. Of the seven patients who exhibited pain symptoms, four and two patients were partly and completely relieved, respectively. Late grade 3 ileus and gastroduodenal bleeding were observed in one patient each. Among the clinicopathological factors evaluated, only a disease-free interval of greater than 18.9 months exhibited a significant association with improved overall survival (p = 0.017). Radiotherapy for isolated locally recurrent pancreatic cancer resulted in encouraging local control, overall survival, and palliative effects with mild toxicity, particularly in patients with a prolonged disease-free interval. This treatment strategy should be prospectively evaluated. (orig.) [German] Beurteilung strahlentherapeutischer Behandlungsergebnisse und prognostischer Faktoren bei rezidivierendem Pankreaskrebs.

    To evaluate preoperative serum levels of Ca125 and Tag72-4 tumour markers and investigate if abnormal levels correlate to mortality and disease-free survival. Retrospective observational study of a cohort of 282 women (mean age 62.3, SD 10.5 years) with primary endometrial cancer included all consecutive cases treated in a tertiary Gynaecological oncology Center. Excluded cases with other cancer or previous cancer treatment, major abdominal pathology or inflammation, endometriosis. Preoperative serum Tag72 and Ca125 levels were determined and evaluated in relation to disease-free survival (DFS) and disease-specific overall survival (DOS). Raised Ca125 correlates to worse overall disease-specific survival (66.1 vs 87.8 months, p = 0.021) and Tag72 correlates to shorter disease-free survival (69.2 vs 67.3 months, p = 0.021) and higher recurrence rate (13.5 vs 6 %, p = 0.021). When both Ca125 and Tag72 are abnormal DFS and DOS are worse. 93.3 % (72.3 months) vs 82.4 %, (61.3 months) p = 0.018 and 96.3 % (74.8 months) vs 88.2 %, (65.9 months) p = 0.021, respectively. This study enhances the value of preoperative tumour markers and their prognostic value. Ca125 and Tag72 appear to be good predictors of poor prognosis in patients with endometrial cancer.

    To evaluate the utility of a standardized qualitative scoring system for treatment response assessment at 18F-FDG PET-CT in patients undergoing chemoradiotherapy for locally advanced cervical carcinoma and correlate this with subsequent patient outcome. Ninety-six consecutive patients with locally advanced cervical carcinoma treated with radical chemoradiotherapy (CRT) in a single centre between 2011 and 2014 underwent 18F-FDG PET-CT approximately 3 months post-treatment. Tumour metabolic response was assessed qualitatively using a 5-point scale ranging from background level activity only through to progressive metabolic disease. Clinical and radiological (MRI pelvis) follow-up was performed in all patients. Progression-free (PFS) and overall survival (OS) was calculated using the Kaplan-Meier method (Mantel-Cox log-rank) and correlated with qualitative score using Chi-squared test. Forty patients (41.7 %) demonstrated complete metabolic response (CMR) on post-treatment PET-CT (Score 1/2) with 38 patients (95.0 %) remaining disease free after a minimum follow-up period of 18 months. Twenty-four patients (25.0 %) had indeterminate residual uptake (ID, Score 3) at primary or nodal sites after treatment, of these eight patients (33.3 %) relapsed on follow-up, including all patients with residual nodal uptake (n = 4). 11 of 17 patients (64.7 %) with significant residual uptake (partial metabolic response, PMR, Score 4) subsequently relapsed. In 15 patients (15.6 %) PET-CT demonstrated progressive disease (PD, Score 5) following treatment. Kaplan-Meier analysis showed a highly statistically significant difference in PFS and OS between patients with CMR, indeterminate uptake, PMR and PD (Log-rank, P < 0.0001). Chi-squared test demonstrated a highly statistically significant association between increasing qualitative score and risk of recurrence or death (P < 0.001).

    Purpose: To determine whether a change in treatment policy to conformal, elective nodal radiotherapy and concurrent high-dose cisplatin improved survival for cervical esophageal cancer patients. Methods and Materials: All cervical esophageal cancer patients treated between 1997 and 2005 were restaged (1983 American Joint Committee on Cancer criteria). Patients treated before 2001 (previous cohort [PC]) were compared with those treated from 2001 onward (recent cohort [RC]). The PC institutional chemoradiotherapy protocol was 54 Gy in 20 fractions within 4 weeks, with 5-fluorouracil (1,000 mg/m 2 ) on Days 1-4 and either mitomycin C (10 mg/m 2 ) or cisplatin (75 mg/m 2 ) on Day 1. The RC institutional chemoradiotherapy protocol was conformal radiotherapy, 70 Gy in 35 fractions within 7 weeks, to the primary tumor and elective nodes, with high-dose cisplatin (100 mg/m 2 ) on Days 1, 22, and 43. Results: The median follow-up was 3.1 years (PC, 8.1 and RC, 2.3). Of 71 patients (25 women and 46 men), 21 of 29 in the PC and 29 of 42 in the RC were treated curatively (curative subgroup, n = 50). Between the two groups, no differences in overall survival or locoregional relapse-free survival were seen. The overall survival rate at 2 and 5 years was 35% (range, 24-47%) and 21% (range, 12-32%) in the whole group and 46% (range 32-60%) and 28% (range, 15-42%) in the curative group, respectively. In the curative group, no statistically significant prognostic factors were found. Trends toward better locoregional relapse-free survival were seen in women (2-year rate, 73% vs. for men, 36%; p = 0.08) and in patients aged >64 years (2-year rate, 68% vs. age ≤64 years, 34%; p = 0.10). Conclusion: No survival improvement could be demonstrated after changing the treatment policy to high-dose cisplatin-based, conventionally fractionated conformal chemoradiotherapy. Female gender and older age might predict for better outcomes

    Posttransplant relapse is still the major cause of treatment failure in high-risk acute leukemia. Attempts to manipulate alloreactive T cells to spare normal cells while killing leukemic cells have been unsuccessful. In HLA-haploidentical transplantation, we reported that donor-derived T regulatory cells (Tregs), coinfused with conventional T cells (Tcons), protected recipients against graft-versus-host disease (GVHD). The present phase 2 study investigated whether Treg-Tcon adoptive immunotherapy prevents posttransplant leukemia relapse. Forty-three adults with high-risk acute leukemia (acute myeloid leukemia 33; acute lymphoblastic leukemia 10) were conditioned with a total body irradiation-based regimen. Grafts included CD34(+) cells (mean 9.7 × 10(6)/kg), Tregs (mean 2.5 × 10(6)/kg), and Tcons (mean 1.1 × 10(6)/kg). No posttransplant immunosuppression was given. Ninety-five percent of patients achieved full-donor type engraftment and 15% developed ≥grade 2 acute GVHD. The probability of disease-free survival was 0.56 at a median follow-up of 46 months. The very low cumulative incidence of relapse (0.05) was significantly better than in historical controls. These results demonstrate the immunosuppressive potential of Tregs can be used to suppress GVHD without loss of the benefits of graft-versus-leukemia (GVL) activity. Humanized murine models provided insights into the mechanisms underlying separation of GVL from GVHD, suggesting the GVL effect is due to largely unopposed Tcon alloantigen recognition in bone marrow. © 2014 by The American Society of Hematology.

    Previous studies have demonstrated that the eradication of Helicobacter pylori (H. pylori) is associated with a significant reduction of the rate of duodenal ulcer (DU) relapse. The aim of this study was to assess the long-term effect of a bismuth-free triple therapy on the eradication of H. pylori and reduction of DU relapse. After informed consent, 61 patients with endoscopically proven DU and H. pylori infection detected on 14C-urea breath test (BT) were included in the study. All patients received a combination of furazolidone, amoxicillin, and metronidazole, three times a day, for 5 days, in addition to eventual classical antiulcer agents prescribed by their attending physicians. BT was repeated after an interval of at least 60 days to evaluate H. pylori eradication. Endoscopy and another BT were performed again at 6.5 months after therapy to detect possible recurrences. Forty-eight patients completed the trial: 26 (54%) patients were negative for H. pylori at 6.5 months after the end of treatment, and 22 (46%) persisted H. pylori positive. Ninety-two percent of the patients in whom the bacteria were eradicated showed endoscopically healed ulcers and were asymptomatic, and two that were symptomatic presented only occasional pain not requiring therapy. Among the 22 patients who persisted H. pylori positive, six (27%) showed endoscopically active ulcers (p = 0.012) and eight (36%) patients continued to be symptomatic (p less than 0.01), and were still using antiulcer drugs (p = 0.002) 6.5 months after treatment. It is concluded that combined treatment with furazolidone, amoxicillin, and metronidazole for 5 days represents a well-tolerated, inexpensive, and effective therapeutic regime for the eradication of H. pylori and abolition of DU relapse in more than 50% of the patients during a follow-up period of 6.5 months

    Purpose: To retrospectively review our institutional experience with hypopharyngeal carcinoma with respect to treatment modality. Methods and Materials: A total of 70 patients with hypopharyngeal cancer treated between 1999 and 2009 were analyzed for functional and survival outcomes. The treatments included surgery alone (n = 5), surgery followed by radiotherapy (RT) (n = 3), surgery followed by chemoradiotherapy (CRT) (n = 13), RT alone (n = 2), CRT alone (n = 22), induction chemotherapy followed by RT (n = 3), and induction chemotherapy followed by CRT (n = 22). Results: The median follow-up was 18 months. The median overall survival and disease-free survival for all patients was 28.3 and 17.6 months, respectively. The 1- and 2-year local control rate for all patients was 87.1% and 80%. CRT, given either as primary therapy or in the adjuvant setting, improved overall survival and disease-free survival compared with patients not receiving CRT. The median overall survival and disease-free survival for patients treated with CRT was 36.7 and 17.6 months vs. 14.0 and 8.0 months, respectively (p < .01). Of the patients initially treated with an organ-preserving approach, 4 (8.2%) required salvage laryngectomy for local recurrence or persistent disease; 8 (16.3%) and 12 (24.5%) patients were dependent on a percutaneous gastrostomy and tracheostomy tube, respectively. The 2-year laryngoesophageal dysfunction-free survival rate for patients treated with an organ-preserving approach was estimated at 31.7%. Conclusions: Concurrent CRT improves survival in patients with hypopharyngeal cancer. CRT given with conventional radiation techniques yields poor functional outcomes, and future efforts should be directed at determining the feasibility of pharyngeal-sparing intensity-modulated radiotherapy in patients with hypopharyngeal tumors.

    To investigate the association between NSUN2/IGF-II signature and ovarian cancer survival. Using a publicly accessible dataset of RNA sequencing and clinical follow-up data, we performed Classification and Regression Tree and survival analyses. Patients with NSUN2 high IGF-II low had significantly superior overall and disease progression-free survival, followed by NSUN2 low IGF-II low , NSUN2 high IGF-II high and NSUN2 low IGF-II high (p IGF-II signature with the risks of death and relapse remained significant in multivariate Cox regression models. Random-effects meta-analyses show the upregulated NSUN2 and IGF-II expression in ovarian cancer versus normal tissues. The NSUN2/IGF-II signature associates with heterogeneous outcome and may have clinical implications in managing ovarian cancer.

    Background For processes that follow first order kinetics, exponential decay nonlinear regression analysis (EDNRA) may delineate curve characteristics and suggest processes affecting curve shape. We conducted a preliminary feasibility assessment of EDNRA of patient survival curves. Methods EDNRA was performed on Kaplan-Meier overall survival (OS) and time-to-relapse (TTR) curves for 323 patients with resected NSCLC and on OS and progression-free survival (PFS) curves from selected publications. Results and Conclusions In our resected patients, TTR curves were triphasic with a “cured” fraction of 60.7% (half-life [t1/2] >100,000 months), a rapidly-relapsing group (7.4%, t1/2=5.9 months) and a slowly-relapsing group (31.9%, t1/2=23.6 months). OS was uniphasic (t1/2=74.3 months), suggesting an impact of co-morbidities; hence, tumor molecular characteristics would more likely predict TTR than OS. Of 172 published curves analyzed, 72 (42%) were uniphasic, 92 (53%) were biphasic, 8 (5%) were triphasic. With first-line chemotherapy in advanced NSCLC, 87.5% of curves from 2-3 drug regimens were uniphasic vs only 20% of those with best supportive care or 1 drug (p<0.001). 54% of curves from 2-3 drug regimens had convex rapid-decay phases vs 0% with fewer agents (p<0.001). Curve convexities suggest that discontinuing chemotherapy after 3-6 cycles “synchronizes” patient progression and death. With postoperative adjuvant chemotherapy, the PFS rapid-decay phase accounted for a smaller proportion of the population than in controls (p=0.02) with no significant difference in rapid-decay t1/2, suggesting adjuvant chemotherapy may move a subpopulation of patients with sensitive tumors from the relapsing group to the cured group, with minimal impact on time to relapse for a larger group of patients with resistant tumors. In untreated patients, the proportion of patients in the rapid-decay phase increased (p=0.04) while rapid-decay t1/2 decreased (p=0.0004) with increasing

    The records of all patients with stage I and II Hodgkin's disease treated with radiotherapy alone at the Royal Adelaide Hospital between 1970 and 1986 were reviewed. The aim was to ensure the results were equivalent to the best reported series, particularly as treating such patients with chemotherapy alone has been shown to produce equivalent overall survival figures with improved relapse-free survival. There were 104 patients of whom 67 and undergone staging laparotomy. Fifty-seven patients were stage I and 47 stage II. Nine patients had B symptoms. Overall survival at 10 years was 83% with disease-specific survival being 86% and relapse-free survival 68%. These results compare favourably with those in the world literature. Multivariate analysis only revealed stage as an independent predictor of improved relapse-free survival. 30 refs., 3 figs., 3 tabs

    The most appropriate treatment for men with prostate cancer and positive pelvic nodes, N+, is an area of active controversy. We report our 5-years outcomes in men with locally advanced prostate cancer (T1-T4N0-N1M0) treated with definitive radiotherapy encompassing the prostate and pelvic lymph nodes (intensity modulated radiotherapy, IMRT) and long-term androgen deprivation therapy (ADT). Of the 138 consecutive eligible men all living patients have been followed up to almost 5 years. Survival endpoints for 5-year biochemical failure-free survival (BFFS), relapse-free survival (RFS), prostate cancer-specific survival (PCSS), and overall survival (OS) were assessed by Kaplan-Meier analysis. Univariate and multivariate Cox regression proportional hazards models were constructed for all survival endpoints. The RTOG morbidity grading system for physician rated toxicity was applied. Patients with locally advanced T3-T4 tumors (35 %) and N1 (51 %) have favorable outcome when long-term ADT is combined with definitive radiotherapy encompassing pelvic lymph nodes. The 5-year BFFS, RFS, PCSS and OS were 71.4, 76.2, 94.5 and 89.0 %, respectively. High Gleason sum (9–10) had a strong independent prognostic impact on BFFS, RFS and OS (p = 0.001, <0.001, and 0.005 respectively). The duration of ADT (= > 28 months) showed a significant independent association with improved PCSS (p = 0.02) and OS (p = 0.001). Lymph node involvement was not associated with survival endpoints in the multivariate analysis. The radiotherapy induced toxicity seen in our study population was moderate with rare Grade 3 GI side effects and up to 11 % for Grade 3 GU consisting mainly of urgency and frequency. Pelvic IMRT in combination with long-term ADT can achieve long-lasting disease control in men with N+ disease and unfavorable prognostic factors.

    The incidence of breast cancer in young women (age < 35) is low. The biology of the disease in this age group is poorly understood, and there are conflicting data regarding the prognosis for these women compared to older patients. We retrospectively analyzed 2040 consecutive primary invasive breast cancer patients who underwent surgical procedures at our institution between 1990 and 1999. The younger age group was defined as patients aged <35 years at the time of diagnosis. The clinicopathological characteristics and treatment outcomes were compared between younger and older age groups. A total of 256 (12.5%) patients were aged <35. There was a significantly higher incidence of nuclear grade 3 and medullary histological-type tumors in younger patients compared to older patients. Axillary lymph node status, T stage, histological grade, c-erbB2 expression and estrogen receptor status did not differ significantly between the two age groups. Younger patients had a greater probability of recurrence and death at all time periods. Although there was no significant difference in disease-free survival between the two age groups in lymph node-negative patients, the younger group showed worse prognosis among lymph node-positive patients (p < 0.001). In multivariate analysis, young age remained a significant predictor of recurrence (p = 0.010). Young age (<35) is an independent risk factor for relapse in operable breast cancer patients

    Profile surveys, completed Rotter I-E scales, and questionnaires on past relapse behavior were collected from 108 New Jersey compulsive gamblers who attended Gamblers Anonymous, and an attempt was made, based on the findings, to predict incidence of compulsive gamblers' relapse. Relationships between I-E scores and extent of relapse-free periods, and I-E scores and relapse, with the variables of religious background, age, marital status, education, type of work, and childhood physical abuse were investigated. In every instance the relationship found was statistically non-significant.

    We reviewed our series of anal squamous cell carcinomas (ASCC) treated over the last two decades. ASCC patients undergoing treatment at the Leicester Royal Infirmary between 1998 and 2016 were selected. Age, gender, pathological tumor characteristics, treatment adopted, the overall survival (OS), cancer-specific survival (CSS), and disease-free survival (DFS) at 5-year follow-up were recorded and calculated. A total of 190 ASCC were reviewed, of these 64.2% (n = 122) received primary radical chemoradiotherapy. Complete response rate was 92.6% (n = 113) and four patients with residual disease underwent a salvage APER. Twenty-eight patients experienced recurrent disease (23.0%) either systemic (n = 8), local (n = 14), or both (n = 6); six had a salvage APER. Complete follow-up data are available for 63.1% patients (77/122). Overall, the locoregional failure rate of primary chemoradiotherapy (residual + recurrent disease) was present in 29 patients (29/122; 23.8%). OS was 41.6% CSS was 69.2% and DFS 60.0% at 5 years follow-up. In our series of ASCC primary chemoradiotherapy had achieved significant initial complete response rates, however, long term-follow ups still present systemic and local recurrences. APR is able to treat 30% of the pelvic recurrences (6/20), the others are either associated with systemic disease or locally inoperable masses. © 2017 Wiley Periodicals, Inc.

    Purpose: To analyze the impact of patient and treatment parameters in concurrent chemoradiation treatment for anal carcinoma. Methods and Materials: Retrospective review of 50 MO anal cancer patients treated from 1984-1994. Most patients received concurrent 5-FU, mitomycin, and radiation. Local control and disease-free/overall survival were determined and analyzed according to patient and treatment parameters. Results: With 43 month median follow-up, projected overall survival is 66% at 5 and 8 years. Disease-free survival is 67% at 5 years and 59% at 8 years. Local control is 70% at 5 and 8 years. Doses of ≥54 Gy are associated with improved 5-year survival (84 vs. 47%, p = 0.02), disease-free survival (74 v. 56%, p = 0.09), and local control (77 vs. 61%, p = 0.04). Although local control, disease-free survival, and overall survival were improved in patients whose overall treatment time was <40 days, this was not statistically significant. Outcome in the four patients with pretreatment hemoglobin (Hgb) <10 appeared worse with 3-year overall survival 50 vs. 68% (p = 0.07), disease-free survival 0 vs. 67% (p = 0.11), and local control 0 vs. 74% (p = 0.05). Projected 5-year overall survival, relapse-free survival, and local control in 4 HIV (+) patients is 0, 75, and 75%. Multivariate analysis reveals that dose (p 0.02) and Hgb (p = 0.05) independently affect local control, dose (p = 0.02) affects disease-free survival, and dose (p = 0.01), Hgb (p = 0.03), T-stage (p = 0.03), and HIV-status (0.07) independently influence overall survival. Conclusion: Radiation doses of ≥54 Gy are associated with significantly improved survival and local control in anal cancer patients treated with chemoradiation. Overall treatment times of less than 40 days are associated with a trend towards improved outcome, but this is not significant. Pretreatment hemoglobin <10 is associated with worse treatment outcome. Survival of HIV (+) patient is poor, but the majority of such patients

    Purpose: To determine the cause of death in children who survive more than 5 years after radiation treatment of a brain tumor. Methods and Material: Nine hundred and twelve consecutive children with a primary brain tumor irradiated at the Princess Margaret Hospital or Toronto-Bayview Regional Cancer Center from 1958 to 1991, were evaluated for long-term outcome. Results: Overall 10- and 20-year survival rates were 44% and 37%. Subsequent survival of 377 5-year survivors was, at an additional 10 and 20 years, 78% and 67%. Most (83%) deaths that occurred more than 5 years from diagnosis were a result of relapse of the original tumor. The 10-year survival rate subsequent to relapse was 9% when the first relapse occurred less than one year from diagnosis, 17% for 1-2 years, and 31% when the time to relapse was 3 years or greater. The cumulative actuarial incidence of, and death from, second malignant tumors at 30 years from diagnosis was 18% and 13%, respectively. Conclusions: Death later than 5 years from diagnosis of a brain tumor in children is common and is usually due to progressive disease in slowly evolving low grade tumors. Death from a second malignant tumor becomes more frequent than death from the original tumor after 15 years from diagnosis.

    Purpose: Constitutively activated signal transducers and activators of transcription (STAT) factors, in particular STAT1, STAT3, and STAT5, have been detected in a wide variety of human primary tumors and have been demonstrated to directly contribute to oncogenesis. However, the expression pattern of these STATs in cervical carcinoma is still unknown, as is whether or not they have prognostic significance. This study investigated the expression patterns of STAT1, STAT3, and STAT5 in cervical cancer and their associations with clinical outcomes in patients treated with radical radiation therapy. Methods and Materials: A total of 165 consecutive patients with International Federation of Gynecology and Obstetrics (FIGO) Stages IB to IVA cervical cancer underwent radical radiation therapy, including external beam and/or high-dose-rate brachytherapy between 1989 and 2002. Immunohistochemical studies of their formalin-fixed, paraffin-embedded tissues were performed. Univariate and multivariate analyses were performed to identify and to evaluate the effects of these factors affecting patient survival. Results: Constitutive activations of STAT1, STAT3, and STAT5 were observed in 11%, 22%, and 61% of the participants, respectively. While STAT5 activation was associated with significantly better metastasis-free survival (p < 0.01) and overall survival (p = 0.04), STAT1 and STAT3 activation were not. Multivariate analyses showed that STAT5 activation, bulky tumor ({>=}4 cm), advanced stage (FIGO Stages III and IV), and brachytherapy (yes vs. no) were independent prognostic factors for cause-specific overall survival. None of the STATs was associated with local relapse. STAT5 activation (odds ratio = 0.29, 95% confidence interval = 0.13-0.63) and advanced stage (odds ratio = 2.54; 95% confidence interval = 1.03-6.26) were independent predictors of distant metastasis. Conclusions: This is the first report to provide the overall expression patterns and prognostic significance of

    The antioxidant lycopene may be beneficial for patients with heart failure (HF). Processed tomato products are a major source of lycopene, although they are also high in sodium. Increased sodium intake may counter the positive antioxidant effect of lycopene. This was a prospective study of 212 patients with HF. Dietary intake of lycopene and sodium was obtained from weighted 4-day food diaries. Patients were grouped by the median split of lycopene of 2471 µg/day and stratified by daily sodium levels above and below 3 g/day. Patients were followed for 1 year to collect survival and hospitalization data. Cox proportional hazards modeling was used to compare cardiac event-free survival between lycopene groups within each stratum of sodium intake. Higher lycopene intake was associated with longer cardiac event-free survival compared with lower lycopene intake (p = 0.003). The worst cardiac event-free survival was observed in the low lycopene intake group regardless of sodium intake (> 3 g/day HR = 3.01; p = 0.027 and ≤ 3 g/day HR= 3.34; p = 0.023). These findings suggest that increased lycopene intake has the potential to improve cardiac event-free survival in patients with HF independent of sodium intake.

    Survival is one of the most central population measures when the effects of the pollution are studied in natural bird populations. However, only few studies have actually measured rigorous survival estimates on adult birds. In recent years there has been a methodological advance in survival analyses by mark-recapture models. We modelled local survival (including mortality and emigration) with the program MARK in a population of a small insectivorous passerine bird, the pied flycatcher (Ficedula hypoleuca), around a point source of heavy metals. The local survival of females in the polluted area was about 50% lower than in the other areas. Males, however, survived relatively well in the heavily polluted area, but showed somewhat lower survival in the moderately polluted area. Different pollution effects between two sexes might be due to pollution-related differences in reproductive effort in females and males, and/or more intensive uptake of heavy metals by laying females. - Female pied flycatchers (Ficedula hypoleuca) show decreased local survival around a copper smelter.

    Purpose: To evaluate the local control rate and complications of a single fraction of high-dose-rate brachytherapy (HDR BT) boost in women aged 45 yeas and younger after breast-conserving therapy. Methods and Materials: Between 1999 and 2007, 167 patients between the ages of 26 and 45 years old (72 were 40 years old or younger), with stages T1 to T2 invasive breast cancer with disease-free margin status of at least 5 mm after breast-conserving surgery received 46 to 50 Gy whole-breast irradiation plus a 7-Gy HDR-BT boost (“fast boost”). An axillary dissection was performed in 72.5% of the patients and sentinel lymph node biopsy in 27.5%. A supraclavicular area was irradiated in 19% of the patients. Chemotherapy was used in 86% of the patients and hormone treatment in 77%. Clinical nodes were present in 18% and pathological nodes in 29%. The pathological stage was pT0: 5%, pTis: 3%, pT1: 69% and pT2: 23%. Intraductal component was present in 40% and 28% were G3. Results: At a median follow-up of 92 months, 9 patients relapsed on the margin of the implant, and 1 patient in another quadrant, resulting in a 10-year local relapse rate of 4.3% and a breast relapse rate of 4.9%, with breast preservation in 93.4%; no case of mastectomy due to poor cosmesis arose. Actuarial 5- and 10-year disease-free, cause-specific, and overall survival rates were 87.9% and 85.8%, and 92.1% and 88.4%, and 92.1% and 87.3%, respectively. In a univariate analysis, triple-negative cases and negative hormone receptors did worse, but in a multivariate analysis, only the last factor was significant for local and breast control. Asymptomatic fibrosis G2 was recorded in 3 cases, and there were no other late complications. Cosmetic results were good to excellent in 97% of cases. Conclusions: A single dose of 7 Gy using the fast-boost technique is well tolerated, with a low rate of late complications and improved local tumor control in women aged 45 and younger, compared to published data

    We have previously published a randomised controlled study of the efficacy of cryotherapy in preventing acute oral mucositis after high-dose chemotherapy for stem cell transplantation. The present study is a 5-year follow-up safety study of survival in these patients. In the previously published study oral cryotherapy (cooling of the oral cavity) during high-dose chemotherapy significantly reduced mucositis grade and opiate use in the treated group. All patients were followed up for at least 5 years with regard to relapse and death rates. Baseline data, transplant complications and mucositis data were compared. Significantly more patients (25/39) who received oral cryotherapy were alive after 5 years compared to 15/39 in the control group (P= 0.025). Relapse rates were similar. The only baseline difference was a lower proportion of patients in complete remission at transplantation in the control group (6 vs. 13, P= 0.047). This 5-year follow-up study gave no support for safety concerns with cryotherapy. © 2012 Blackwell Publishing Ltd.

    Purpose: To investigate conventional prognostic factors for ipsilateral breast tumor recurrence (IBTR), distant metastasis (DM), and survival after breast-conserving therapy (BCT) in screen-detected and symptomatic cases on surveillance up to 25 years. Patients and Methods: A total of 1812 consecutive patients in three cohorts (1981-1989, 1990-1992, and 1993-1998) with T12N01M0 invasive breast cancer were treated with BCT (median follow-up, 14 years). Tumor type and grade were reviewed by a single pathologist. Hormone receptor status was measured by immunohistochemistry on tissue microarrays. A Cox proportional hazards model was used to assess independent prognostic variables for relapse and survival. Results: A total of 205 IBTR occurred, with 5-, 10-, 15-, and 20-year actuarial relapse rates of 4.5% (95% confidence interval [CI] 3.35-5.5%), 8.4% (95% CI 7.1-9.8%), 14.1% (95% CI 12.0-16%), and 17.4% (95% CI 14.5-20.2%). Number of nodes, young age, pathologic tumor size, and multifocality were significant factors for IBTR. Three hundred seventy-eight patients developed DM. The actuarial metastatic rate was 12% at 5 years and 17.9% at 10 years. Young age, number of positive nodes, pathologic tumor size, and tumor grade were significant factors for DM relapse. When conventional prognostic indices were taken into account screen-detected cancers showed no improvement in overall relapse or survival rate compared with symptomatic cases but did show a reduced risk of DM after IBTR. After 10 years IBTR relapse continued at a constant rate of 0.87% per annum. Conclusions: The Edinburgh BCT series has shown that screen-detected invasive breast cancers do not have significantly different clinical outcomes compared with symptomatic cases when pathologic risk factors are taken into account. This suggests that these patients be managed in a similar way.

    Purpose: To determine, in the setting of advanced-stage of Hodgkin lymphoma (HL), whether relapses occur in the irradiated planning target volume and whether the definition of local radiation therapy (RT) used by the German Hodgkin Study Group (GHSG) is adequate, because there is no harmonization of field and volume definitions among the large cooperative groups in the treatment of advanced-stage HL. Methods and Materials: All patients with residual disease of ≥2.5 cm after multiagent chemotherapy (CTX) were evaluated using additional positron emission tomography (PET), and those with a PET-positive result were irradiated with 30 Gy to the site of residual disease. We re-evaluated all sites of disease before and after CTX, as well as the PET-positive residual tumor that was treated in all relapsed patients. Documentation of radiation therapy (RT), treatment planning procedures, and portal images were carefully analyzed and compared with the centrally recommended RT prescription. The irradiated sites were compared with sites of relapse using follow-up computed tomography scans. Results: A total of 2126 patients were enrolled, and 225 patients (11%) received RT. Radiation therapy documents of 152 irradiated patients (68%) were analyzed, with 28 irradiated patients (11%) relapsing subsequently. Eleven patients (39%) had an in-field relapse, 7 patients (25%) relapsed outside the irradiated volume, and an additional 10 patients (36%) showed mixed in- and out-field relapses. Of 123 patients, 20 (16%) with adequately performed RT relapsed, compared with 7 of 29 patients (24%) with inadequate RT. Conclusions: The frequency and pattern of relapses suggest that local RT to PET-positive residual disease is sufficient for patients in advanced-stage HL. Insufficient safety margins of local RT may contribute to in-field relapses.

    The high failure rates in the radiotherapy (RT) target volume suggest that patients with locally advanced oesophageal cancer (LAOC) would benefit from increased total RT doses. High 2-deoxy-2-[{sup 18}F]fluoro-D-glucose (FDG) uptake (hotspot) on pre-RT FDG positron emission tomography (PET)/CT has been reported to identify intra-tumour sites at increased risk of relapse after RT in non-small cell lung cancer and in rectal cancer. Our aim was to confirm these observations in patients with LAOC and to determine the optimal maximum standardized uptake value (SUV{sub max}) threshold to delineate smaller RT target volumes that would facilitate RT dose escalation without impaired tolerance. The study included 98 consecutive patients with LAOC treated by chemoradiotherapy (CRT). All patients underwent FDG PET/CT at initial staging and during systematic follow-up in a single institution. FDG PET/CT acquisitions were coregistered on the initial CT scan. Various subvolumes within the initial tumour (30, 40, 50, 60, 70, 80 and 90 % SUV{sub max} thresholds) and in the subsequent local recurrence (LR, 40 and 90 % SUV{sub max} thresholds) were pasted on the initial CT scan and compared[Dice, Jaccard, overlap fraction (OF), common volume/baseline volume, common volume/recurrent volume]. Thirty-five patients had LR. The initial metabolic tumour volume was significantly higher in LR tumours than in the locally controlled tumours (mean 25.4 vs 14.2 cc; p = 0.002). The subvolumes delineated on initial PET/CT with a 30-60 % SUV{sub max} threshold were in good agreement with the recurrent volume at 40 % SUV{sub max} (OF = 0.60-0.80). The subvolumes delineated on initial PET/CT with a 30-60 % SUV{sub max} threshold were in good to excellent agreement with the core volume (90 % SUV{sub max}) of the relapse (common volume/recurrent volume and OF indices 0.61-0.89). High FDG uptake on pretreatment PET/CT identifies tumour subvolumes that are at greater risk of recurrence after CRT in

    Defibrotide is a novel orally bioavailable polydisperse oligonucleotide with anti-thrombotic and anti-adhesive effects. In SCID/NOD mice, defibrotide showed activity in human myeloma xenografts. This phase I/II study was conducted to identify the most appropriate dose of defibrotide in combination with melphalan, prednisone and thalidomide in patients with relapsed and relapsed/refractory multiple myeloma, and to determine its safety and tolerability as part of this regimen. This was a phase I/II, multicenter, dose-escalating, non-comparative, open label study. Oral melphalan was administered at a dose of 0.25 mg/kg on days 1-4, prednisone at a dose of 1.5 mg/kg also on days 1-4 and thalidomide at a dose of 50-100 mg/day continuously. Defibrotide was administered orally at three dose-levels: 2.4, 4.8 or 7.2 g on days 1-4 and 1.6, 3.2, or 4.8 g on days 5-35. Twenty-four patients with relapsed/refractory multiple myeloma were enrolled. No dose-limiting toxicity was observed. In all patients, the complete response plus very good partial response rate was 9%, and the partial response rate was 43%. The 1-year progression-free survival and 1-year overall survival rates were 34% and 90%, respectively. The most frequent grade 3-4 adverse events included neutropenia, thrombocytopenia, anemia and fatigue. Deep vein thrombosis was reported in only one patient. This combination of melphalan, prednisone and thalidomide together with defibrotide showed anti-tumor activity with a favorable tolerability. The maximum tolerated dose of defibrotide was identified as 7.2 g p.o. on days 1-4 followed by 4.8 g p.o. on days 5-35. Further trials are needed to confirm the role of this regimen and to evaluate the combination of defibrotide with new drugs.

    To investigate the influence of an isopropanolic Cimicifuga racemosa extract (iCR) on recurrence-free survival after breast cancer, including estrogen-dependent tumors. This pharmacoepidemiologic observational retrospective cohort study examined breast cancer patients treated at general, gynecological and internal facilities linked to a medical database in Germany. The main endpoint was disease-free survival following a diagnosis of breast cancer. The impact of treatment with iCR following diagnosis was analyzed by Cox-proportional hazards models, controlling for age and other confounders. Of 18,861 patients, a total of 1,102 had received an iCR therapy. The mean overall observation time was 3.6 years. Results showed that iCR was not associated with an increase in the risk of recurrence but associated with prolonged disease-free survival. After 2 years following initial diagnosis, 14% of the control group had developed a recurrence, while the iCR group reached this proportion after 6.5 years. The primary Cox regression model controlling for age, tamoxifen use and other confounders demonstrated a protractive effect of iCR on the rate of recurrence (hazard ratio 0.83, 95% confidence interval 0.69 0.99). This effect remained consistent throughout all variations of the statistical model, including subgroup analyses. TNM status was unknown but did not bias the iCR treatment decision as investigated separately. Hence, it was assumed to be equally distributed between treatment groups. Correlation analyses showed good internal and external validity of the database. An increase in the risk of breast cancer recurrence for women having had iCR treatment, compared to women not treated with iCR is unlikely.

    To analyze the impact of weight loss before and during chemoradiation on survival outcomes in patients with locally advanced head and neck cancer. From 07/1994-07/2000 a total of 224 patients with squamous cell carcinoma of the head and neck were randomized to either hyperfractionated radiation therapy alone or the same radiation therapy combined with two cycles of concomitant cisplatin. The primary endpoint was time to any treatment failure (TTF); secondary endpoints were locoregional recurrence-free survival (LRRFS), distant metastasis-free survival (DMFS) and overall survival (OS). Patient weight was measured 6 months before treatment, at treatment start and treatment end. The proportion of patients with >5% weight loss was 32% before, and 51% during treatment, and the proportion of patients with >10% weight loss was 12% before, and 17% during treatment. After a median follow-up of 9.5 years (range, 0.1 – 15.4 years) weight loss before treatment was associated with decreased TTF, LRRFS, DMFS, cancer specific survival and OS in a multivariable analysis. However, weight loss during treatment was not associated with survival outcomes. Weight loss before and during chemoradiation was commonly observed. Weight loss before but not during treatment was associated with worse survival

    Background: The role of adjuvant postoperative therapy after resection of localised malignant melanoma involving regional lymph nodes remains controversial. There are no randomised trials that confirm that postoperative radiation conveys a benefit in terms of regional control or survival. Methods: Two hundred and thirty-four patients with melanoma involving lymph nodes were registered on a prospective study to evaluate the effect of postoperative radiation therapy. The regimen consisted of 48 Gy in 20 fractions to the nodal basin using recommended treatment guidelines for each of the major node sites. The primary endpoints were regional in-field relapse and late toxicity. Secondary endpoints were adjacent relapse, distant relapse, overall survival, progression-free survival and time to in-field progression. Results: Adjuvant radiation therapy was well tolerated by all of the patients. As the first site of relapse, regional in-field relapses occurred in 16/234 patients (6.8%). The overall survival was 36% at 5 years. The progression-free survival and regional control rates were 27% and 91%, respectively, at 5 years. Patients with more than 2 nodes involved had a significantly worse outcome in terms of distant relapse, overall and progression-free survival. Conclusion: We believe that adjuvant radiation therapy following nodal surgery could offer a possible benefit in terms of regional control. These results require confirmation in a randomised trial

    Purpose: To investigate local control, survival outcomes, and predictors of local relapse for patients treated with spine stereotactic body radiation therapy. Methods and Materials: We reviewed the records of 332 spinal metastases consecutively treated with stereotactic body radiation therapy between 2002 and 2012. The median follow-up for all living patients was 33 months (range, 0-111 months). Endpoints were overall survival and local control (LC); recurrences were classified as either in-field or marginal. Results: The 1-year actuarial LC and overall survival rates were 88% and 64%, respectively. Patients with local relapses had poorer dosimetric coverage of the gross tumor volume (GTV) compared with patients without recurrence (minimum dose [Dmin] biologically equivalent dose [BED] 23.9 vs 35.1 Gy, P<.001; D98 BED 41.8 vs 48.1 Gy, P=.001; D95 BED 47.2 vs 50.5 Gy, P=.004). Furthermore, patients with marginal recurrences had poorer prescription coverage of the GTV (86% vs 93%, P=.01) compared with those with in-field recurrences, potentially because of more upfront spinal canal disease (78% vs 24%, P=.001). Using a Cox regression univariate analysis, patients with a GTV BED Dmin ≥33.4 Gy (median dose) (equivalent to 14 Gy in 1 fraction) had a significantly higher 1-year LC rate (94% vs 80%, P=.001) compared with patients with a lower GTV BED Dmin; this factor was the only significant variable on multivariate Cox analysis associated with LC (P=.001, hazard ratio 0.29, 95% confidence interval 0.14-0.60) and also was the only variable significant in a separate competing risk multivariate model (P=.001, hazard ratio 0.30, 95% confidence interval 0.15-0.62). Conclusions: Stereotactic body radiation therapy offers durable control for spinal metastases, but there is a subset of patients that recur locally. Patients with local relapse had significantly poorer tumor coverage, which was likely attributable to treatment planning directives that prioritized the

    The aim of the present study was to investigate the feasibility of measuring metabolic tumor burden using [F-18] fluorodeoxyglucose ((18) F-FDG) positron emission tomography/computed tomography (PET/CT) in patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) treated with bendamustine-rituximab. Because the standardized uptake value is a critical parameter of tumor characterization, we carried out a phantom study of (18) F-FDG PET/CT to ensure quality control for 28 machines in the 24 institutions (Japan, 17 institutions; Korea, 7 institutions) participating in our clinical study. Fifty-five patients with relapsed or refractory DLBCL were enrolled. The (18) F-FDG PET/CT was acquired before treatment, after two cycles, and after the last treatment cycle. Treatment response was assessed after two cycles and after the last cycle using the Lugano classification. Using this classification, remission was complete in 15 patients (27%) and incomplete in 40 patients (73%) after two cycles of therapy, and remission was complete in 32 patients (58%) and incomplete in 23 patients (42%) after the last treatment cycle. The percentage change in all PET/CT parameters except for the area under the curve of the cumulative standardized uptake value-volume histogram was significantly greater in complete response patients than in non-complete response patients after two cycles and the last cycle. The Cox proportional hazard model and best subset selection method revealed that the percentage change of the sum of total lesion glycolysis after the last cycle (relative risk, 5.24; P = 0.003) was an independent predictor of progression-free survival. The percent change of sum of total lesion glycolysis, calculated from PET/CT, can be used to quantify the response to treatment and can predict progression-free survival after the last treatment cycle in patients with relapsed or refractory DLBCL treated with bendamustine-rituximab. © 2014 The Authors.

    Few studies of ethnicity and prostate cancer have included Latino men in analyses of baseline clinical characteristics, treatment selection, and disease-free survival (DFS). The present study examines the impact of Latino ethnicity on these parameters in a large, multiinstitutional database of men with prostate cancer. We compared baseline disease characteristics and clinical outcomes for Latino (N = 138), non-Latino White (NLW, N = 5619), and African-American (AA, N = 608) men with localized prostate cancer by using chi-square and ANOVA for baseline variables and survival analysis to examine differences in time to recurrence. Latino men resembled AA men more than NLW on sociodemographic characteristics. AA men had higher Gleason scores and prostate-specific antigen (PSA) at diagnosis than Latino or NLW men (both P Latino and AA men presented with advanced disease (T3b/T4/N+/M+) versus 4% of NLW (P Latino men did not receive different treatments than NLW or AA men after controlling for clinical and demographic factors; however, AA men were more likely to receive external beam radiation (OR = 1.51, 95% confidence interval [CI] = 0.99-2.31) and hormone treatment (OR = 1.56, 95% CI = 1.05-2.32) then NLW men. For prostatectomy patients, 3-year actuarial DFS rates were 83% for NLW men and 86% for Latino men versus 69% for AA men (P Latinos are more similar to African Americans on sociodemographic characteristics but more similar to NLW on clinical presentation, treatments received, and DFS.

    Relapse remains the leading cause of treatment failure in children with acute lymphoblastic leukaemia (ALL) undergoing allogeneic haematopoietic stem cell transplantation (HSCT). We retrospectively investigated the prognostic role of minimal residual disease (MRD) before and after HSCT in 119 children transplanted in complete remission (CR). MRD was measured by polymerase chain reaction in bone marrow samples collected pre-HSCT and during the first and third trimesters after HSCT (post-HSCT1 and post-HSCT3). The overall event-free survival (EFS) was 50%. The cumulative incidence of relapse and non-relapse mortality was 41% and 9%. Any degree of detectable pre-HSCT MRD was associated with poor outcome: EFS was 39% and 18% in patients with MRD positivity <1 × 10 -3 and ≥1 × 10 -3 , respectively, versus 73% in MRD-negative patients (P < 0·001). This effect was maintained in different disease remissions, but low-level MRD had a very strong negative impact only in patients transplanted in second or further CR. Also, MRD after HSCT enabled patients to be stratified, with increasing MRD between post-HSCT1 and post-HSCT3 clearly defining cohorts with a different outcome. MRD is an important prognostic factor both before and after transplantation. Given that MRD persistence after HSCT is associated with dismal outcome, these patients could benefit from early discontinuation of immunosuppression, or pre-emptive immuno-therapy. © 2018 John Wiley & Sons Ltd.

    The success of treatment for substance use issues varies with personal and social factors, including the composition and structure of the individual's personal support network. This paper describes the personal support networks and social capital of a sample of Italian adults after long-term residential therapeutic treatment for substance use issues, and analyses network correlates of post-treatment substance use (relapse). Using a social network analysis approach, data were obtained from structured interviews (90-120 min long) with 80 former clients of a large non-governmental therapeutic treatment agency in Italy providing voluntary residential treatments and rehabilitation services for substance use issues. Participants had concluded the program at least six months prior. Data were collected on socio-demographic variables, addiction history, current drug use status (drug-free or relapsed), and the composition and structure of personal support networks. Factors related to risk of relapse were assessed using bivariate and multivariate logistic regression models. A main goal of this study was to identify differences between the support network profiles of drug free and relapsed participants. Drug free participants had larger, less dense, more heterogeneous and reciprocal support networks, and more brokerage social capital than relapsed participants. Additionally, a lower risk of relapse was associated with higher socio-economic status, being married/cohabiting, and having network members with higher socio-economic status, who have greater occupational heterogeneity, and reciprocate support. Post-treatment relapse was found to be negatively associated with the socioeconomic status and occupational heterogeneity of ego's support network, reciprocity in the ties between ego and network members, and a support network in which the members are relatively loosely connected with one another (i.e., ego possesses "brokerage social capital"). These findings suggest the

    Patients on surveillance for clinical stage I (CSI) testicular cancer are counseled regarding their baseline risk of relapse. The conditional risk of relapse (cRR), which provides prognostic information on patients who have survived for a period of time without relapse, have not been determined for CSI testicular cancer. To determine cRR in CSI testicular cancer. We reviewed 1239 patients with CSI testicular cancer managed with surveillance at a tertiary academic centre between 1980 and 2014. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: cRR estimates were calculated using the Kaplan-Meier method. We stratified patients according to validated risk factors for relapse. We used linear regression to determine cRR trends over time. At orchiectomy, the risk of relapse within 5 yr was 42.4%, 17.3%, 20.3%, and 12.2% among patients with high-risk nonseminomatous germ cell tumor (NSGCT), low-risk NSGCT, seminoma with tumor size ≥3cm, and seminoma with tumor size testicular cancer is very low. Consideration should be given to adapting surveillance protocols to individualized risk of relapse based on cRR as opposed to static protocols based on baseline factors. This strategy could reduce the intensity of follow-up for the majority of patients. Our study is the first to provide data on the future risk of relapse during surveillance for clinical stage I testicular cancer, given a patient has been without relapse for a specified period of time.

    Full Text Available Abstract Background Gefitinib, a tyrosine kinase inhibitor, is an effective treatment in advanced non-small cell lung cancer (NSCLC patients with an activating mutation in the epidermal growth factor receptor (EGFR. Randomised clinical trials showed a benefit in progression free survival for gefitinib versus doublet chemotherapy regimens in patients with an activated EGFR mutation (EGFR M+. From a patient perspective, progression free survival is important, but so is health-related quality of life. Therefore, this analysis evaluates the Quality Adjusted progression free survival of gefitinib versus three relevant doublet chemotherapies (gemcitabine/cisplatin (Gem/Cis; pemetrexed/cisplatin (Pem/Cis; paclitaxel/carboplatin (Pac/Carb in a Dutch health care setting in patients with EGFR M+ stage IIIB/IV NSCLC. This study uses progression free survival rather than overall survival for its time frame in order to better compare the treatments and to account for the influence that subsequent treatment lines would have on overall survival analysis. Methods Mean progression free survival for Pac/Carb was obtained by extrapolating the median progression free survival as reported in the Iressa-Pan-Asia Study (IPASS. Data from a network meta-analysis was used to estimate the mean progression free survival for therapies of interest relative to Pac/Carb. Adjustment for health-related quality of life was done by incorporating utilities for the Dutch population, obtained by converting FACT-L data (from IPASS to utility values and multiplying these with the mean progression free survival for each treatment arm to determine the Quality Adjusted progression free survival. Probabilistic sensitivity analysis was carried out to determine 95% credibility intervals. Results The Quality Adjusted progression free survival (PFS (mean, (95% credibility interval was 5.2 months (4.5; 5.8 for Gem/Cis, 5.3 months (4.6; 6.1 for Pem/Cis; 4.9 months (4.4; 5.5 for Pac/Carb and 8

    Solitary plasmacytoma of bone (SPB) and extramedullary plasmacytoma (EMP) are rare. High local control rates are reported with radiotherapy, although the optimal dose and extent of radiotherapy portals remains controversial. Between 1983 and 1993, 30 patients with solitary plasmacytoma were seen at the Regional Cancer Centre, Trivandrum, India. 23 patients had SPB and seven EMP. The mean age was 52 years and the male to female ratio 3.2:1. Diagnosis of SPB was confirmed by biopsy in 16 patients and tumour excision in seven. 20 patients received megavoltage radiotherapy to the bone lesion with limited margins, and one received chemotherapy. Two patients who underwent complete tumour excision received no further treatment. All seven patients with EMP received megavoltage radiotherapy, four following biopsy and three after tumour excision. Local control was achieved in all patients with SPB. Nine progressed to multiple myeloma and one developed a solitary plasmacytoma in another bone. Six patients with EMP achieved local control. Three later progressed to multiple myeloma and one had local relapse. Median time to relapse was 28 months in SPB and 30 months in EMP. 5-year overall survival rates were 82% and 57% for patients with SPB and EMP, respectively. The corresponding progression free survival rates were 55% and 50%, respectively. Age, sex, site of tumour, serum M protein and haemoglobin levels did not significantly influence progression free survival. The extent of surgery, radiotherapy dose or time to relapse were not significant prognostic factors. Radiotherapy appears to be an effective modality of treatment of solitary plasmacytoma. No dose-response relationship is observed, and high local control rates are achieved with limited portals. Progression to multiple myeloma is the commonest pattern of failure, although no prognostic factors for progression are identified. The role of chemotherapy in preventing disease progression needs further evaluation.

    Although docetaxel significantly improves survival in a variety of malignancies, its clinical utility is severely restricted by acquired chemoresistance and disease relapse. To uncover the mechanisms underlying these all too common occurrences, an abundance of research has focused on mutations and gene expression patterns; however, these findings are yet to translate into improved outcomes for patients being administered this drug. These analyses have overlooked a promising lead in the quest to discern key mediators of resistance and relapse following docetaxel therapy: polyploidization. This process is manifested following docetaxel-mediated mitotic arrest by the appearance of giant, multinucleated cells, which slipped from mitosis without undergoing cytokinesis. Polyploid cells generally possess supernumerary centrosomes, are chromosomally instable, and resist chemotherapy. We thus suspect that chemoresistance and relapse following treatment with docetaxel might be combatted by co-administration of centrosome declustering drugs, which could selectively destroy polyploid cells given that normal cells do not possess amplified centrosomes, an intriguing paradigm that warrants further investigation.

    Following promising results to increase survival and reduce treatment burden in intracranial non-germinomatous germ cell tumors (NGGCTs), we conducted a European study using dose-intense chemotherapy followed by risk-adapted radiotherapy. All patients received 4 courses of cisplatin/etoposide/ifosfamide. Non-metastatic patients then received focal radiotherapy only (54 Gy); metastatic patients received 30 Gy craniospinal radiotherapy with 24 Gy boost to primary tumor and macroscopic metastatic sites. Patients with localized malignant NGGCT (n = 116) demonstrated 5-year progression-free survival (PFS) and overall survival (OS) of 0.72 ± 0.04 and 0.82 ± 0.04, respectively. Primary tumor sites were: 67 pineal, 35 suprasellar, 5 bifocal, 9 others. One patient died postsurgery in clinical remission; 3 patients progressed during treatment and 27 (23%) relapsed afterward. Fourteen were local, 6 combined, and 7 distant relapses (outside radiation field). Seventeen of the 27 relapsed patients died of disease. Patients with metastatic disease (n = 33) demonstrated 5-year PFS and OS of 0.68 ± 0.09 and 0.75 ± 0.08, respectively; 1 patient died following progression on treatment and 9 (27%) relapsed afterward (5 local, 1 combined, 3 distant). Only one metastatic patient with recurrence was salvaged. Multivariate analysis identified diagnostic alpha-fetoprotein level (serum and/or cerebrospinal fluid level >1000 ng/mL, 19/149 patients, of whom 11 relapsed; P < 0.0003) and residual disease following treatment, including after second-look surgery (n = 52/145 evaluable patients, 26 relapsed; P = 0.0002) as significant prognostic indicators in this cohort. In localized malignant NGGCT, craniospinal radiotherapy could be avoided without increased relapses outside the radiotherapy field. Chemotherapy and craniospinal radiotherapy remain the gold standard for metastatic disease. © The Author(s) 2017. Published by Oxford University Press on behalf of the Society for Neuro

    Full text: To determine the overall survival and gastrointestinal toxicity for patients treated with salvage definitive chemo-radiotherapy after primary surgery for locoregional relapse of oesophageal carcinoma. A retrospective review of 525 patients who had a resection for oesophageal or oesophagogastric carcinoma at Princess Alexandra Hospital identified 14 patients treated with salvage definitive radiotherapy or chemo-radiotherapy, following localized recurrence of their disease. We analysed the patient and treatment characteristics to determine the median overall survival as the primary end point. Gastrointestinal toxicity was examined to determine if increased toxicity occurred when the stomach was irradiated within the intrathoracic radiotherapy field. The median overall survival for patients treated with curative intent using salvage definitive chemo-radiotherapy was 16 months and the 2-year overall survival is 21%. One patient is in clinical remission more than 5 years after therapy. Age <60 years old and nodal recurrence were favourable prognostic factors. Treatment compliance was 93% with only one patient unable to complete the intended schedule. Fourteen per cent of patients experienced grade 3 or 4 gastrointestinal toxicity. Salvage definitive chemo-radiotherapy should be considered for good performance status patients with oesophageal carcinoma who have a locoregional relapse after primary surgery. The schedule is tolerable with low toxicity and an acceptable median survival

    1983-01-01

    From May, 1979 to March, 1981, 76 leukemia patients were prepared for bone marrow transplantation (BMT) with a new hyperfractionated total body irradiation (TBI) regimen (1320 cGy in 11 fractions, 3x/day), followed by cyclophosphamide, 60 mg/kg, for two days. Partial lung shielding was done on each treatment, with supplemental electron beam treatments of the chest wall to compensate, and of the testes, a sanctuary site. This regimen was initiated to potentially reduce fatal interstitial pneumonitis as well as decrease leukemic relapse. Overall actuarial survival at 1 year for acute non-lymphocytic leukemia (ANLL) patients is 63%, while relapse-free survival at 1 year is 53%. On the other hand, for acute lymphocytic leukemia (ALL) patients, there is no significant difference between relapse or remission patients with regard to overall survival or relapse-free survival, when relapse is defined as > 5% blasts in the marrow at the time of cytoreduction. Overall actuarial survival at 1 year for ALL is 61% and relapse-free survival is 45% at 1 year. Fatal interstitial pneumonitis has dropped to 18% compared with 50% in our previous single-dose TBI regimen (1000 cGy), in which the same doses of cyclophosphamide were given prior to TBI. In conclusion, not only has fatal interstitial pneumonitis been reduced by hyperfractionation and partial lung blocking, but there may be a survival advantage in ALL patients in relapse, who have a survival equal to that of remission patients. This may indicate a greater cell kill with the higher dose (1320 cGy) attained with this regimen, in these patients with a higher leukemic cell burden

    This paper explores the applicability of a mechanistic survival model, based on the distribution of clonogens surviving a course of fractionated radiation therapy, to clinical data on patients with prostate cancer. The study was carried out using data on 1100 patients with clinically localized prostate cancer who were treated with three-dimensional conformal radiation therapy. The patients were stratified by radiation dose (group 1: <67.5 Gy; group 2: 67.5-72.5 Gy; group 3: 72.5-77.5 Gy; group 4: 77.5-87.5 Gy) and prognosis category (favourable, intermediate and unfavourable as defined by pre-treatment PSA and Gleason score). A relapse was recorded when tumour recurrence was diagnosed or when three successive prostate specific antigen (PSA) elevations were observed from a post-treatment nadir PSA level. PSA relapse-free survival was used as the primary end point. The model, which is based on an iterated Yule process, is specified in terms of three parameters: the mean number of tumour clonogens that survive the treatment, the mean of the progression time of post-treatment tumour development and its standard deviation. The model parameters were estimated by the maximum likelihood method. The fact that the proposed model provides an excellent description both of the survivor function and of the hazard rate is prima facie evidence of the validity of the model because closeness of the two survivor functions (empirical and model-based) does not generally imply closeness of the corresponding hazard rates. The estimated cure probabilities for the favourable group are 0.80, 0.74 and 0.87 (for dose groups 1-3, respectively); for the intermediate group: 0.25, 0.51, 0.58 and 0.78 (for dose groups 1-4, respectively) and for the unfavourable group: 0.0, 0.27, 0.33 and 0.64 (for dose groups 1-4, respectively). The distribution of progression time to tumour relapse was found to be independent of prognosis group but dependent on dose. As the dose increases the mean progression

    Full Text Available Abstract Background This study evaluated the effectiveness and safety of preoperative chemoradiotherapy with capecitabine in patients with locally advanced resectable rectal cancer. This report summarizes the results of the phase II study together with long-term (5-year follow-up. Methods Between June 2004 and January 2005, 57 patients with operable, clinical stage II-III adenocarcinoma of the rectum entered the study. Radiation dose was 45 Gy delivered as 25 fractions of 1.8 Gy. Concurrent chemotherapy with oral capecitabine 825 mg/m2 twice daily was administered during radiotherapy and at weekends. Surgery was scheduled 6 weeks after the completion of the chemoradiotherapy. Patients received four cycles of postoperative chemotherapy comprising either capecitabine 1250 mg/m2 bid days 1-14 every 3 weeks or bolus i.v. 5-fluorouracil 425 mg/m2/day and leucovorin 20 mg/m2/day days 1-5 every 4 weeks (choice was at the oncologist's discretion. Study endpoints included complete pathological remission, proportion of R0 resections and sphincter-sparing procedures, toxicity, survival parameters and long-term (5-year rectal and urogenital morbidity assessment. Results One patient died after receiving 27 Gy because of a pulmonary embolism. Fifty-six patients completed radiochemotherapy and had surgery. Median follow-up time was 62 months. No patients were lost to follow-up. R0 resection was achieved in 55 patients. A complete pathological response was observed in 5 patients (9.1%; T-, N- and overall downstaging rates were 40%, 52.9% and 49.1%, respectively. The 5-year overall survival rate, recurrence-free survival, and local control was 61.4% (95% CI: 48.9-73.9%, 52.4% (95% CI: 39.3-65.5%, and 87.4% (95% CI: 75.0-99.8%, respectively. In 5 patients local relapse has occurred; dissemination was observed in 19 patients and secondary malignancies have occurred in 2 patients.

    Stomach adenocarcinoma represents a major health problem and is regarded as the second commonest cause of cancer-associated mortality, universally, since it is still difficult to be perceived at a curable stage. Several lines of evidence have pointed out that the expression of L-Dopa decarboxylase (DDC) gene and/or protein becomes distinctively modulated in several human neuroendocrine neoplasms as well as adenocarcinomas. In order to elucidate the clinical role of DDC on primary gastric adenocarcinomas, we determined qualitatively and quantitatively the mRNA levels of the gene with regular PCR and real-time PCR by using the comparative threshold cycle method, correspondingly, and detected the expression of DDC protein by immunoblotting in cancerous and normal stomach tissue specimens. A statistically significant association was disclosed between DDC expression and gastric intestinal histotype as well as tumor localization at the distal third part of the stomach (p = 0.025 and p = 0.029, respectively). Univariate and multivariate analyses highlighted the powerful prognostic importance of DDC in relation to disease-free survival and overall survival of gastric cancer patients. According to Kaplan-Meier curves, the relative risk of relapse was found to be decreased in DDC-positive (p = 0.031) patients who, also, exhibited higher overall survival rates (p = 0.016) than those with DDC-negative tumors. This work is the first to shed light on the potential clinical usefulness of DDC, as an efficient tumor biomarker in gastric cancer. The provided evidence underlines the propitious predictive value of DDC expression in the survival of stomach adenocarcinoma patients.

    Purpose: The outcome of recurrent ependymoma in children is dismal. Reirradiation has been proposed as an effective modality for ependymoma at relapse. However, the toxicity and outcome benefits of this approach have not been well established. Methods and Materials: We conducted a retrospective population-based study of all patients with recurrent ependymoma treated between 1986 and 2010 in our institution. Demographic, treatment, and outcome data were analyzed for the entire cohort. Results: Of 113 patients with intracranial ependymoma, 47 patients relapsed. At the time of relapse, 29 patients were treated with surgical resection and/or chemotherapy, and 18 patients received full-dose ({>=}54 Gy focal and/or craniospinal) reirradiation with or without surgery at recurrence. Reirradiation was tolerated well with no severe acute complications noticed. Three-year overall survival was 7% {+-} 6% and 81% {+-} 12% for nonreirradiated and reirradiated patients, respectively (p < 0.0001). Time to second progression after reirradiation was significantly longer than time to first progression. This surprising phenomenon was associated with improved progression-free survival for tumors with evidence of DNA damage (n = 15; p = 0.002). At a mean follow-up of 3.73 years, only 2/18 patients had endocrine dysfunction, and 1 patient required special education support. However, a decline in intellectual function from pre- to postreirradiation assessment was observed. Conclusions: Reirradiation is an effective treatment that may change the natural history of recurrent ependymoma in children. However, this change may be associated with increased neurocognitive toxicity. Additional follow-up is needed to determine the risk of late recurrence, secondary radiation-induced tumors, and long-term functional outcome of these patients.

    Standard treatment for locally advanced clinical N2 lung cancer is definitive chemoradiotherapy, and induction chemoradiotherapy(IND-CRT) followed by surgery is an option. Most of them recurs remotely within a few years after initial therapy. Patients who received salvage surgery(SAL) after definitive chemoradiotherapy had no remote relapse for some period after definitive chemoradiotherapy, thus the outcome of SAL may be better than those of IND-CRT, but the operative risks of both procedures seem to be high. To compare the prognosis and risk of SAL and IND-CRT. From January 2001 through December 2015, 39 patients with clinical N2 primary lung cancer underwent surgery after chemoradiotherapy. Twenty-six patients received IND-CRT, and 13 underwent SAL. Perioperative factors, overall survival rates at 5 years, lung-cancer-specific mortality, relapse-free survival rates, and the rates of perioperative complications were compared between the groups. The median follow up period was 41.0 months(5~120 months). Twelve patients were women, and 27 were men. The average age was 60.2 years. The patients comprised 1.7% of the 2,330 anatomical resections performed during the same period. The radiation dose was 46.4 Gy who received IND-CRT and 61.4 Gy in those who received SAL(pperformed in 37 patients, pneumonectomy in 2 patients. In patients who received IND-CRT, an average operation time was 236 minutes, mean bleeding volume was 135 g. In patients who underwent SAL, they were 236 minutes and 188 g(p=0.998, p=0.365). There was no perioperative and in-hospital death in either group. Postoperative complications developed in 5 of INDCRT(19.2%)and 3 in SAL(23.1%). The 5-year overall survival rate of all cases was 60.4%(IND-CRT 53.9, SAL 81.8%;p=0.737). The lung cancer-specific survival rate at 5 years was 60.4% overall, 57.5% in IND-CRT, and 90.0% in SAL(p=0.176). The 5-year relapse-free survival rate was 52.7% overall, 37.6% in IND-CRT, 57.7% in SAL(p=0.175). Although the

    After local excision of early rectal cancer, revision radical resection is recommended for patients with high-risk pathologic stage T1 (pT1) or pT2 cancer, but the revision procedure has high morbidity rates. We evaluated the efficacy of adjuvant concurrent chemoradiotherapy (CCRT) for reducing recurrence after local excision in these patients. Eighty-three patients with high-risk pT1 or pT2 rectal cancer underwent postoperative adjuvant CCRT after local excision. We defined high-risk features as pT1 having tumor size ≤3 cm, and/or resection margin (RM) ≤3 mm, and/or lymphovascular invasion (LVI), and/or non-full thickness excision such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD), or unknown records regarding those features, or pT2 cancer. Radiotherapy was administered with a median dose of 50.4 Gy in 1.8 Gy fraction size over 5-7 weeks. Concurrent 5-fluorouracil and leucovorin were administered for 4 days in the first and fifth weeks of radiotherapy. The median interval between local excision and radiotherapy was 34 (range, 11-104) days. Fifteen patients (18.1 %) had stage pT2 tumors, 22 (26.5 %) had RM of ≥3 mm, and 21 (25.3 %) had tumors of ≥3 cm in size. Thirteen patients (15.7 %) had LVI. Transanal excision was performed in 58 patients (69.9 %) and 25 patients (30.1 %) underwent EMR or ESD. The median follow-up was 61 months. The 5-year overall survival (OS), locoregional relapse-free survival (LRFS), and disease-free survival (DFS) rates for all patients were 94.9, 91.0, and 89.8 %, respectively. Multivariate analysis did not identify any significant factors for OS or LRFS, but the only significant factor affecting DFS was the pT stage (p = 0.027). In patients with high-risk pT1 rectal cancer, adjuvant CCRT after local excision could be an effective alternative treatment instead of revision radical resection. However, patients with pT2 stage showed inferior DFS compared to pT1.

    Background: The 5-year survival of patients with completely resected node-positive gastric cancer ranges from 15% to 25%. We explored the feasibility of a chemoradiation regime consisting of concomitant hyperfractionated radiotherapy and 5-fluorouracil protracted venous infusion (5-FU PVI). Materials and Methods: Forty patients received a total or partial gastrectomy operation and D2 nodal resection for Stage III gastric cancer; they were then irradiated by linac with 6-15-MV photons. The target included the gastric bed, the anastomosis, stumps, and regional nodes. A total dose of 55 Gy was given in 50 fractions using 1.1 Gy b.i.d. All patients received a concomitant 200 mg/m2/day 5-FU PVI. Patients were examined during the follow-up period as programmed. Toxicity was recorded according to RTOG criteria. Results: After a median follow-up of 75.6 months (range: 22-136 months), 24 (60%) patients had died, and 16 (40%) were alive and free of disease. The 5-year actuarial incidence of relapse was 39%, 22%, and 2% for distant metastases, out-field peritoneal seeding, and in-field local regional recurrences, respectively. The 5-year actuarial cause-specific survival was 43%. Three patients survived more than 11 years. Acute ≥ Grade 3 toxicity consisted of hematologic (22.5%) and gastrointestinal toxicity (nausea and vomiting 22.5%, diarrhea 2.8%, and abdominal pain 2.6%). No late toxicity was observed. Conclusion: This regime of concomitant 5-FU PVI and hyperfractionated radiotherapy was well tolerated and resulted in successful locoregional control and satisfactory survival

    Background and purpose: We analyzed the clinical outcome of breast cancer patients carrying sequence variants in the ATM gene who received postoperative radiotherapy after breast conservative surgery to test whether an increased cellular radiosensitivity may translate into enhanced tumor cell killing and thereby result in an improvement of the therapeutic ratio. Patients and methods: We investigated a cohort of 138 breast cancer patients who received adjuvant radiotherapy following breast conservative surgery for T1 and T2 tumors. Genomic DNA samples of these patients had previously been scanned for mutations in the ATM gene. Follow-up data were available in 135 patients, with a median follow-up of 87 months. Local relapse-free, metastasis-free and overall survival were compared between carriers and non-carriers of a sequence variant in the ATM gene. Results: Twenty patients were found to carry a sequence variant in the ATM gene (truncating, 7; missense, 13). The actuarial 7-year local relapse-free survival of carriers vs. non-carriers were 88 vs. 94% (P=0.34). Actuarial metastasis-free and overall survival after 7 years were 63 vs. 85% (P=0.01) and 73 vs. 89% (P=0.055), respectively. However, the presence of a variant in the ATM gene did not remain a significant discriminator for metastasis-free survival in a multivariate Cox regression analysis (P=0.068). Conclusions: Our results do not support the hypothesis that breast cancer patients carrying a sequence variant in the ATM gene differentially benefit from postoperative radiotherapy. These findings have to be verified using larger number of cases to clarify the clinical consequences of sequence variants in the ATM gene

    Allogeneic stem cell transplantation (allo-SCT) is a potentially curative treatment for high-risk acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). For patients with relapsed disease after transplantation, intensive chemotherapy followed by donor lymphocyte infusion (DLI) or a second allo-SCT may result in a durable response in some patients. High-intensity chemotherapy and less aggressive therapy with hypomethylating agents (HAs) with and without DLI are often used for relapse after allo-SCT. Here we compared the treatment outcomes of intensive chemotherapy with that of HAs in relapsed AML and MDS after allo-SCT. Patients who had received a second SCT within 90 days of the relapse date were excluded. The primary endpoints were overall response rate (ORR) and overall survival (OS). Secondary endpoints were complete remission (CR) rate and progression-free survival (PFS). One hundred patients were included: 73 patients received chemotherapy and 27 patients received an HA. Fifty-six percent of patients in the chemotherapy group and 33% of patients in the HA group received at least 1 DLI after treatment. Treatment with chemotherapy resulted in a higher ORR (51% versus 19%, P = .004) and a higher CR rate (40% versus 7%, P = .002). The median OS (6 versus 3.9 months, P = .01) and PFS (4.9 versus 3.8 months, P = .02) were longer in the chemotherapy group. Similar benefit of chemotherapy over HAs was maintained in all treatment outcomes after controlling for the use of DLI. The use of chemotherapy followed by DLI offered the greatest benefit (ORR, 68%; CR, 59%, 1-year OS, 44%; and median OS, 9.8 months). In conclusion, in our hands, with limited numbers, the use of more conventional salvage chemotherapy, with DLI when possible, for the treatment of relapsed AML and MDS after allo-SCT is associated with better outcomes than nonchemotherapy (HA) options.

    Full Text Available Abstract The efficacy and safety of chidamide, a new subtype-selective histone deacetylase (HDAC inhibitor, have been demonstrated in a pivotal phase II clinical trial, and chidamide has been approved by the China Food and Drug Administration (CFDA as a treatment for relapsed or refractory peripheral T cell lymphoma (PTCL. This study sought to further evaluate the real-world utilization of chidamide in 383 relapsed or refractory PTCL patients from April 2015 to February 2016 in mainland China. For patients receiving chidamide monotherapy (n = 256, the overall response rate (ORR and disease control rate (DCR were 39.06 and 64.45%, respectively. The ORR and DCR were 51.18 and 74.02%, respectively, for patients receiving chidamide combined with chemotherapy (n = 127. For patients receiving chidamide monotherapy and chidamide combined with chemotherapy, the median progression-free survival (PFS was 129 (95% CI 82 to 194 days for the monotherapy group and 152 (95% CI 93 to 201 days for the combined therapy group (P = 0.3266. Most adverse events (AEs were of grade 1 to 2. AEs of grade 3 or higher that occurred in ≥5% of patients receiving chidamide monotherapy included thrombocytopenia (10.2% and neutropenia (6.2%. For patients receiving chidamide combined with chemotherapy, grade 3 to 4 AEs that occurred in ≥5% of patients included thrombocytopenia (18.1%, neutropenia (12.6%, anemia (7.1%, and fatigue (5.5%. This large real-world study demonstrates that chidamide has a favorable efficacy and an acceptable safety profile for refractory and relapsed PTCL patients. Chidamide combined with chemotherapy may be a new treatment choice for refractory and relapsed PTCL patients but requires further investigation.

    Peripheral blood lymphocyte counts and stimulations by PHA and PPD in vitro were examined before and up to four years after local pre- or post-operative radiation therapy of 99 patients with breast cancer. The patient material was divided into those who remained clinically disease-free during a follow up period of 4.5-7 years and those who relapsed. Radiation therapy reduced the lymphocyte counts and PPD response to the same levels in both groups of patients; there were no essential differences in their recoveries, with the exception of a somewhat delayed recovery of the PPD-response in the patients who relapsed. PHA responses of the lymphocytes were not decreased following radiation therapy. The data indicate that these radiation induced changes of the peripheral lymphocyte population were similar both in patients who relapsed and those who remained symptom free. A group of 47 women with breast cancer that was treated by surgery only was examined similarly as a comparison. Patients from this group who developed local recurrences had higher lymphocyte counts than those who remained disease-free; patients who developed distant metastases had somewhat decreased PHA responses

    We retrospectively analyzed the treatment outcomes of post-operative radiation therapy (PORT) after radical surgery for locally advanced hypopharyngeal carcinoma. From August 2000 to July 2009, 62 patients with hypopharyngeal squamous cell carcinoma were treated with radical surgery followed by PORT in our institute. All patients were followed up for more than 6 months or until any events. All patients underwent a total laryngectomy and neck node dissection prior to PORT. There were 55 male and 7 female patients, with ages ranging from 45 to 82 years (median: 64). Pathologic stage was IVA in 55 and IVB in 7 patients. Irradiation dose ranged from 46 to 70 Gy (median: 60). Twenty-four patients received concurrent chemotherapy. The median follow-up period for surviving patients was 43 months. The 3-year overall and relapse-free survival rates were 56% and 51%, respectively. There was 1 patient with local recurrence and 9 patients with neck node recurrence, and the 3-year loco-regional control rate was 85%. There were 16 patients with distant metastases and the 3-year freedom form distant metastasis rate was 71%. Patients with extra nodal invasion (ENI) had a statistically poorer prognosis (p=0.008). The incidence rate of loco-regional recurrence and distant metastasis were statistically higher in the patients with ENI (p=0.017 and p=0.009, respectively). PORT with concurrent chemotherapy is deemed to be a standard treatment for such high-risk patients. Conformal and precise radiation treatment such as IMRT might also be considered for such high-risk patients in the near future. (author)

    Purpose: Several reports have documented the prognostic value of a post-irradiation nadir PSA of ≤1 ng/ml in prostatic cancer patients. The purpose of this study was to determine which pre-treatment and treatment-related variables impact upon achieving such nadir levels. Materials and Methods: Between January 1987 and June 1995, 740 patients with clinically localized prostate cancer were treated with 3-dimensional conformal radiotherapy (3D-CRT). 214 (29%) patients were treated with neo-adjuvant androgen ablation prior to therapy and were excluded from this analysis. Among the 526 evaluable patients, the clinical stage were as follows: T 1 C=128 (24%); T 2 A=76 (14%); T 2 B=116 (22%); T 2 C=99 (19%) and T 3 =107 (21%). The prescription dose to the planning target volume (PTV) was 64.8-68.4 Gy in 87 patients (17%); 70.2 Gy in 191 (36%); 75.6 Gy in 209 (40%) and 81 Gy in 39 (7%). The median pre-treatment PSA value was 11.2 ng/ml (range 0.3-114). The median follow-up was 20 months (range: 6-76 months). Results: 242 patients (46%) had PSA levels which declined to ≤1.0 ng/ml. The median time to a nadir level of ≤1.0 was 15.6 months (range: 1-43 months) from completion of 3D-CRT. 154 (29%) patients continued to show declining PSA levels within the first 2 years after therapy, and 130 patients (25%) failed to nadir at PSA levels of ≤1.0 ng/ml. Among patients with nadir PSA levels ≤1, the 3 year PSA relapse-free survival was 91% compared to 29% for patients with nadir PSA levels >1 ng/ml (p<0.0001). A Cox-regression analysis demonstrated that nadir PSA ≤1 was the strongest predictor of PSA relapse-free survival (p<0.001) followed by Gleason score ≤ 6 (p<0.001) and stage< T3 (p=0.004). Among patients who received doses of ≥75.6 Gy, the likelihood of achieving PSA nadir levels ≤1.0 at 24 and 36 months was 86% and 93%, respectively, compared to 74 and 80%, respectively, among those who received lower doses (p<0.001). Doses of ≥75.6 Gy was the strongest

    Objectives It is unknown if preoperative tracheostomy for persistent/recurrent laryngeal squamous cell carcinoma (LSCC) plays a role in unrecognized local disease spread and disease recurrence after salvage laryngectomy. The goals of this study were to determine the effect of preoperative tracheostomy on disease-free survival (DFS) in patients with recurrent/persistent LSCC undergoing salvage laryngectomy. Study Design Retrospective case series derived from prospectively maintained database. Setting Tertiary care academic center. Subjects Patients with recurrent/persistent LSCC after radiation/chemoradiation (RT/CRT) who underwent salvage laryngectomy at the University of Michigan from 1997 to 2015. Methods Demographic, clinical, pathologic, and survival data were collected. Kaplan-Meier survival estimates were performed. Results DFS was worse for patients with tracheostomy prior to laryngectomy than patients without a tracheostomy (5 year: 39% vs 67%; P tracheostomy prior to RT/CRT compared to patients with tracheostomy after RT/CRT or patients without a tracheostomy had worse DFS (5-year: 25%, 49%, and 67%, respectively; P tracheostomy was associated with worse DFS. In multivariable analysis, presence of a preoperative tracheostomy had a worse DFS (hazard ratio, 1.63; 95% confidence interval, 1.00-2.67; P = .048). Conclusion Preoperative tracheostomy is associated with disease recurrence in patients with persistent/recurrent LSCC undergoing salvage laryngectomy, particularly in patients who had tracheostomy prior to completion of initial RT/CRT. Notably, preoperative tracheostomy as a causal factor vs marker for disease recurrence is difficult to ascertain. Nevertheless, clinicians should be aware of the increased risk of locoregional recurrence in patients with preoperative tracheostomy when counseling on surgical salvage and when considering the role of additional therapy.

    Purpose: To evaluate the role of postoperative radiotherapy (RT) in Merkel cell carcinoma (MCC). Methods and Materials: A retrospective multicenter study was performed in 180 patients with MCC treated between February 1988 and September 2009. Patients who had had surgery alone were compared with patients who received surgery and postoperative RT or radical RT. Local relapse-free survival (LRFS), regional relapse-free survival (RRFS), and distant metastasis-free survival (DMFS) rates were assessed together with disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) rates. Results: Seventy-nine patients were male and 101 patients were female, and the median age was 73 years old (range, 38-93 years). The majority of patients had localized disease (n = 146), and the remaining patients had regional lymph node metastasis (n = 34). Forty-nine patients underwent surgery for the primary tumor without postoperative RT to the primary site; the other 131 patients received surgery for the primary tumor, followed by postoperative RT (n = 118) or a biopsy of the primary tumor followed by radical RT (n = 13). Median follow-up was 5 years (range, 0.2-16.5 years). Patients in the RT group had improved LRFS (93% vs. 64%; p < 0.001), RRFS (76% vs. 27%; p < 0.001), DMFS (70% vs. 42%; p = 0.01), DFS (59% vs. 4%; p < 0.001), and CSS (65% vs. 49%; p = 0.03) rates compared to patients who underwent surgery for the primary tumor alone; LRFS, RRFS, DMFS, and DFS rates remained significant with multivariable Cox regression analysis. However OS was not significantly improved by postoperative RT (56% vs. 46%; p = 0.2). Conclusions: After multivariable analysis, postoperative RT was associated with improved outcome and seems to be an important component in the multimodality treatment of MCC.

    Ibrutinib, a potent and irreversible small-molecule inhibitor of both Bruton's tyrosine kinase and interleukin-2 inducible kinase (ITK), has been used to treat relapsed/refractory chronic lymphocytic leukemia (CLL) with prolongation of progression-free and overall survival. Here, we present 27 patients with relapsed CLL following allogeneic hematopoietic cell transplant (HCT) who subsequently received ibrutinib salvage therapy. Sixteen of these patients were part of multi-institutional clinical trials and achieved an overall response rate of 87.5%. An additional 11 patients were treated at Stanford University following US Food and Drug Administration approval of ibrutinib; 7 (64%) achieved a complete response, and 3 (27%) achieved a partial response. Of the 9 patients treated at Stanford who had mixed chimerism-associated CLL relapse, 4 (44%) converted to full donor chimerism following ibrutinib initiation, in association with disease response. Four of 11 (36%) patients evaluated by ClonoSeq achieved minimal residual disease negativity with CLL ibrutinib was discontinued, in 1 case even after 26 months. None of the 27 patients developed graft-versus-host-disease (GVHD) following ibrutinib initiation. We postulate that ibrutinib augments the graft-versus-leukemia (GVL) benefit through a T-cell-mediated effect, most likely due to ITK inhibition. To investigate the immune modulatory effects of ibrutinib, we completed comprehensive immune phenotype characterization of peripheral B and T cells from treated patients. Our results show that ibrutinib selectively targets pre-germinal B cells and depletes Th2 helper cells. Furthermore, these effects persisted after drug discontinuation. In total, our results provide evidence that ibrutinib effectively augments GVL without causing GVHD. © 2016 by The American Society of Hematology.

    As the key element, sensor networks are widely investigated by the Internet of Things (IoT) community. When massive numbers of devices are well connected, malicious attackers may deliberately propagate fake position information to confuse the ordinary users and lower the network survivability in belt-type situation. However, most existing positioning solutions only focus on the algorithm accuracy and do not consider any security aspects. In this paper, we propose a comprehensive scheme for node localization protection, which aims to improve the energy-efficient, reliability and accuracy. To handle the unbalanced resource consumption, a node deployment mechanism is presented to satisfy the energy balancing strategy in resource-constrained scenarios. According to cooperation localization theory and network connection property, the parameter estimation model is established. To achieve reliable estimations and eliminate large errors, an improved localization algorithm is created based on modified average hop distances. In order to further improve the algorithms, the node positioning accuracy is enhanced by using the steepest descent method. The experimental simulations illustrate the performance of new scheme can meet the previous targets. The results also demonstrate that it improves the belt-type sensor networks' survivability, in terms of anti-interference, network energy saving, etc.

    To evaluate whether Point A asymmetry in low dose-rate (LDR) brachytherapy is associated with local control (LC), disease-free survival (DFS) and/or overall survival (OS). A retrospective analysis of disease control and survival outcomes was conducted for patients who underwent LDR brachytherapy for advanced cervical cancer. Institutional protocol entailed concurrent chemotherapy and whole pelvis radiotherapy (WPRT) over 5 weeks, followed by placement of Fletcher-Suit tandem and colpostat applicators at weeks 6 and 8. Objective Point A doses, 80-85 Gy, were accomplished by placement of Cesium-137 (Cs-137) sources. Cox proportional hazards regression models were used to assess associations between disease control and survival endpoints with variables of interest. The records of 50 patients with FIGO stage IB1-IVA cervical cancer undergoing LDR brachytherapy at our institution were identified. Thirty of these patients had asymmetry > 2.5%, and 11 patients had asymmetry > 5%. At a median survivor follow-up of 20.25 months, 15 patients had experienced disease failure (including 5 cervical/vaginal apex only failures and 2 failures encompassing the local site). Right/left dose asymmetry at Point A was associated with statistically significantly inferior LC (p = 0.035) and inferior DFS (p = 0.011) for patients with mean Point A dose of > 80 Gy. Insufficient evidence existed to conclude an association with OS. LDR brachytherapy may be associated with clinically significant dose asymmetry. The present study demonstrates that patients with Point A asymmetry have a higher risk of failure for DFS and LC.

    The aim of this study was to report long-term results of patients with locally advanced rectal cancer treated by neoadjuvant chemoradiotherapy with fluorouracil, leucovorin, and oxaliplatin. From February 2002 to November 2006, a total of 58 patients with locally advanced rectal cancer were recruited. Secondary endpoints included the cumulative incidence of local and distant recurrences, disease-free survival, and overall survival. The median follow-up time was 138 months (109-151 months). The cumulative incidence of local recurrence at 10 years was 12.1%. The cumulative incidence of distant recurrence at 10 years was 53.4%. The overall survival in the intention-to-treat population was 39.5% at 10 years. Disease-free survival in the intention-to-treat population was 41.8% at 10 years. Univariate analysis revealed that pathologic complete response was associated with local recurrence, distant recurrence, disease-free survival, and overall survival (p rectal cancer after preoperative chemoradiotherapy and total mesorectal excision. Pathologic complete response is an independent prognostic factor for locally advanced rectal cancer after preoperative chemoradiotherapy.

    This study investigated the diagnostic performance and prognostic value of fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT in suspected malignant pleural mesothelioma (MPM) recurrence, in the context of patterns and intensity of FDG uptake, histologic type, and treatment algorithm. Fifty patients with MPM underwent FDG PET/CT for restaging 11 {+-} 6 months after therapy. Tumor relapse was confirmed by histopathology, and by clinical evolution and subsequent imaging. Progression-free survival was defined as the time between treatment and the earliest clinical evidence of recurrence. Survival after FDG PET/CT was defined as the time between the scan and death or last follow-up. Overall survival was defined as the time between initial treatment and death or last follow-up date. Treatment failure was confirmed in 42 patients (30 epithelial and 12 non-epithelial MPM). Sensitivity, specificity, accuracy, negative predictive value, and positive predictive value for FDG PET/CT were 97.6, 75, 94, 86, and 95.3%, respectively. FDG PET/CT evidence of single site of recurrence was observed in the ipsilateral hemithorax in 18 patients (44%), contralaterally in 2 (5%), and in the abdomen in 1 patient (2%). Bilateral thoracic relapse was detected in three patients (7%). Simultaneous recurrence in the ipsilateral hemithorax and abdomen was observed in ten (24%) patients and in seven (17%) in all three cavities. Unsuspected distant metastases were detected in 11 patients (26%). Four patterns of uptake were observed in recurrent disease: focal, linear, mixed (focal/linear), and encasing, with a significant difference between the intensity of uptake in malignant lesions compared to benign post-therapeutic changes. Lesion uptake was lower in patients previously treated with more aggressive therapy and higher in intrathoracic lesions of patients with distant metastases. FDG PET/CT helped in the selection of 12 patients (29%) who benefited from additional previously

Unsuspected distant metastases were detected in 11 patients (26%). Four patterns of uptake were observed in recurrent disease: focal, linear, mixed (focal/linear), and encasing, with a significant difference between the intensity of uptake in malignant lesions compared to benign post-therapeutic changes. Lesion uptake was lower in patients previously treated with more aggressive therapy and higher in intrathoracic lesions of patients with distant metastases. FDG PET/CT helped in the selection of 12 patients (29%) who benefited from additional previously

    Relapsed or primary refractory Hodgkin's lymphoma (HL) patients refractory to first-line salvage chemotherapy (first salvage) and unable to undergo high-dose chemotherapy (HDC) and autologous stem cell transplant (auto-SCT) have very poor outcome. Some patients are offered second-line salvage chemotherapy (second salvage), if they are responsive and may receive HDC auto-SCT. We identified 31 patients (18 males, 13 females) from 1996-2012 who received second salvage prior to auto-SCT. Median age at auto-SCT is 22 years. Patients were grouped as (1) relapsed-refractory (Rel:Ref): patients with prior complete response (CR) and on relapse found refractory to first salvage and received second salvage and (2) refractory-refractory (Ref:Ref): patients refractory to both primary treatment and first salvage and received second salvage. Median follow-up is 63 months (18-170). Disease status after second salvage prior to HDC was CR 16 %, partial response (PR) 71 % and stable disease 13 %. After HDC auto-SCT, CR:PR: progressive disease was observed in 18 (58 %): four (12 %): nine (29 %) patients, respectively. Five-year overall survival (OS) for whole group is 57 % (Rel:Ref vs. Ref:Ref, 73 % vs. 48 %, p = 0.48). Progression-free survival (PFS) for whole group is 52 % (Rel:Ref vs. Ref:Ref, 73 % vs. 40 % respectively, p = 0.11). Second-line salvage is a valid approach with no long-term side effects for those HL patients who do not respond to first-line salvage chemotherapy and they can be candidate of HDC and stem cell transplant with a high ORR, the PFS and OS in relapse-refractory and refractory-refractory group of patients.

    Purpose: To investigate conventional prognostic factors for ipsilateral breast tumor recurrence (IBTR), distant metastasis (DM), and survival after breast-conserving therapy (BCT) in screen-detected and symptomatic cases on surveillance up to 25 years. Patients and Methods: A total of 1812 consecutive patients in three cohorts (1981–1989, 1990–1992, and 1993–1998) with T12N01M0 invasive breast cancer were treated with BCT (median follow-up, 14 years). Tumor type and grade were reviewed by a single pathologist. Hormone receptor status was measured by immunohistochemistry on tissue microarrays. A Cox proportional hazards model was used to assess independent prognostic variables for relapse and survival. Results: A total of 205 IBTR occurred, with 5-, 10-, 15-, and 20-year actuarial relapse rates of 4.5% (95% confidence interval [CI] 3.35–5.5%), 8.4% (95% CI 7.1–9.8%), 14.1% (95% CI 12.0–16%), and 17.4% (95% CI 14.5–20.2%). Number of nodes, young age, pathologic tumor size, and multifocality were significant factors for IBTR. Three hundred seventy-eight patients developed DM. The actuarial metastatic rate was 12% at 5 years and 17.9% at 10 years. Young age, number of positive nodes, pathologic tumor size, and tumor grade were significant factors for DM relapse. When conventional prognostic indices were taken into account screen-detected cancers showed no improvement in overall relapse or survival rate compared with symptomatic cases but did show a reduced risk of DM after IBTR. After 10 years IBTR relapse continued at a constant rate of 0.87% per annum. Conclusions: The Edinburgh BCT series has shown that screen-detected invasive breast cancers do not have significantly different clinical outcomes compared with symptomatic cases when pathologic risk factors are taken into account. This suggests that these patients be managed in a similar way.

    Full text of publication follows: purpose: to describe outcome of patients with muscle-invasive bladder carcinoma treated with multimodality therapy in our institution from 1993 to 2002. Patients and methods: the charts of sixty patients with T2-4, N0-1, M0 treated with TURBT followed by a chemo-radiotherapy combination were retrospectively reviewed: 22 received neo-adjuvant chemotherapy (CMV/MVAC) followed by concomitant chemo-radiotherapy (weakly cisplatin/carbo-platin or a cisplatin and 5-fluorouracil association) and the other 38 concomitant chemo-radiotherapy alone. Radiotherapy delivered a median dose of 45 Gy to the pelvis and 65 Gy to the bladder in a mono-fractionated or twice a day fractionation scheme. Follow-up evaluations included cystoscopy with biopsies at regular intervals. Salvage cystectomy was recommended in case of local persistent tumor or bladder relapse. Results: median follow-up was 48.5 months (10-126 months). 82% (18/22) of the patients receiving neo-adjuvant chemotherapy had 2 or more cycles and 85% (51/60) got the concomitant chemotherapy as planned. Radiotherapy was completed in 56 patients. Twenty-eight patients relapsed either locally (14 did not achieve local complete response after chemo-radiation and 6 had true local relapse during follow-up) or at distant sites. Actuarial 5-year disease-specific survival and freedom from local and distant relapse rate are respectively 54% and 42%. Actuarial local control rate with intact bladder was 56% at 5-year. When separated according to stage and grade, patients with T2/3 grade 2 tumors had significantly better chance of remaining relapse-free than the others (p = 0.045). Salvage cystectomy (n = 11) for isolated local failure in this population achieved limited results. Conclusion: our experience shows that a significant number of patients will achieve long survival with their bladder intact after multimodality therapy. (authors)

    Our purpose as to evaluate the impact of adjuvant radioactive iodine therapy (RAI) on prognosis, as assessed by progression-free survival (PFS) and overall survival (OS), in patients affected by differentiated thyroid carcinoma (DTC) lymph-node relapse and previously treated with lymphadenectomy. We retrospectively evaluated DTC patients treated with lymph-node dissection for disease relapse. All patients had previously undergone total thyroidectomy and radioiodine remnant ablation (RRA). We used clinical and histological data obtained during follow-up to assess response and outcome. By means of univariate and multivariate time-to-event analyses, we assessed the impact of RAI on outcome (PFS and OS) and the prognostic role of thyroglobulin (Tg) levels under suppression with levothyroxine (Tg-on) measured 1-3 months after lymphadenectomy and of other risk factors. We evaluated 113 patients (age at diagnosis: median 41 years, interquartile range: 31-59), 64 of whom were treated with RAI. Over a median follow-up time of 5.7 years, 27 patients showed disease progression and 13 died. Kaplan-Meier PFS and OS curves showed that age on diagnosis, tumor histology, tumor size, DTC aggressive variant, and Tg-on were associated with prognosis. Patients with Tg-on ≥1 ng/ml treated with RAI showed a better PFS (Log-rank pp 0.001) and OS (p = 0.005) than untreated patients, while no effect of RAI was observed in patients with Tg-on <1 ng/ml. Multivariate models showed that age, Tg-on (≥1 vs. < 1 ng/ml, HR: 18.2, 95% CI: 5.09-64.8, p = 0.001) and RAI (Yes vs. No, HR: 0.36,95%CI: 0.15-0. 9, p = 0.02) remained the only independent factors associated with PFS, but only age and Tg-on remained significantly associated with OS (HR: 8.31, 95%CI:1.56-44.3, p = 0.01). Nonetheless, patients treated with RAI showed a lower risk of mortality (HR: 0.34, 95%CI: 0.1-1.15 p = 0.08) than untreated patients. RAI after lymphadenectomy for DTC relapse is significantly associated with better PFS

    Full Text Available Abstract Background/aims Breast cancer metastasis suppressor 1 (BRMS1 blocks metastasis in melanoma xenografts; however, its usefulness as a biomarker in human melanomas has not been widely studied. The goal was to measure BRMS1 expression in benign nevi, primary and metastatic melanomas and evaluate its impact on disease progression and prognosis. Methods Paraffin-embedded tissue from 155 primary melanomas, 69 metastases and 15 nevi was examined for BRMS1 expression using immunohistochemistry. siRNA mediated BRMS1 down-regulation was used to study impact on invasion and migration in melanoma cell lines. Results A significantly higher percentage of nevi (87%, compared to primary melanomas (20% and metastases (48%, expressed BRMS1 in the nucelus (p Waf1/Cip1 (p = 0.009. Cytoplasmic score index was inversely associated with nuclear p-Akt (p = 0.013 and positively associated with cytoplasmic p-ERK1/2 expression (p = 0.033. Nuclear BRMS1 expression in ≥ 10% of primary melanoma cells was associated with thicker tumors (p = 0.016 and decreased relapse-free period (p = 0.043. Nuclear BRMS1 was associated with expression of fatty acid binding protein 7 (FABP7; p = 0.011, a marker of invasion in melanomas. In line with this, repression of BRMS1 expression reduced the ability of melanoma cells to migrate and invade in vitro. Conclusion Our data suggest that BRMS1 is localized in cytoplasm and nucleus of melanocytic cells and that cellular localization determines its in vivo effect. We hypothesize that cytoplasmic BRMS1 restricts melanoma progression while nuclear BRMS1 possibly promotes melanoma cell invasion.

    This article reports risk factors and long-term outcome in localized nonparameningeal head and neck rhabdomyosarcomas in children and adolescents from a combined dataset from 3 consecutive international trials. Data from 140 children (9.3% of total) prospectively enrolled in the International Society of Pediatric Oncology Malignant Mesenchymal Tumor (SIOP-MMT)-84/89/95 studies were analyzed. Primary site was: superficial face in 46%; oral cavity (21%); neck (19%); and salivary glands (14%). Local control was achieved in 96%, but 49% relapsed (locoregionally 91%). At median follow-up of 10 years, 5-year overall survival (OS) was 74.7% (67.4% to 81.9%) and event-free survival 48.9% (40.6% to 57.2%), although this improved with successive studies. Radiotherapy (RT) as first-line treatment was independently prognostic for event-free survival (relative risk [RR] = 0.4 [range, 0.2-0.7]; p < .01) even if it did not impact OS (RR = 1 [range, 0.5-2]). High rates of locoregional relapse were seen in head and neck rhabdomyosarcoma that should be prevented by more frequent use of RT in this primary. © 2016 Wiley Periodicals, Inc.
