    Full Text Available A growing body of evidence suggests that breast cancer recurrence risk is linked to lifestyle behaviors. This study examined correlations between breast cancer recurrence, risk reduction beliefs, and related behaviors among African American breast cancer survivors (AA BCSs. Study participants included 191 AA BCSs, mean age = 56.3 years, who completed a lifestyle assessment tool. Most respondents believed that being overweight (52.7%, lack of physical activity (48.7%, and a high fat diet (63.2% are associated with breast cancer recurrence. Over 65% considered themselves overweight; one third (33.5% agreed that losing weight could prevent recurrence, 33.0% disagreed, while the remaining 33.5% did not know; and nearly half (47.9% believed that recurrence could be prevented by increasing physical activity. Almost 90% survivors with BMI < 25 Kg/M2 reported no recurrence compared to 75.7% with BMI ≥ 25 Kg/M2 (p = 0.06; nearly all of the women (99.2% answered “yes” to seeking professional help to lose weight, 79.7% of which were recurrence-free (p = 0.05. These results provide information about AA BCSs’ beliefs and behaviors protective against breast cancer recurrence. Additional research is warranted to determine the effectiveness of educational interventions for AA BCSs that promote consumption of a healthy diet and engaging in regular physical activity.

    Despite a growing literature on the psychosocial impact of the threat of cancer recurrence, underserved populations, such as those from the Appalachian region, have been understudied. To examine worry and perceived risk in cancer survivors, Appalachian and non-Appalachian cancer patients at an ambulatory oncology clinic in a university hospital were surveyed. Appalachians had significantly higher worry than non-Appalachians. Cancer type and lower need for cognition were associated with greater worry. Those with missing perceived risk data were generally older, less educated, and lower in monitoring, blunting, and health literacy. Additional resources are needed to assist Appalachians and those with cancers with poor prognoses (e.g., liver cancer, pancreatic cancer) to cope with worry associated with developing cancer again. More attention for cancer prevention is critical to improve quality of life in underserved populations where risk of cancer is greater. PMID:21240722

    AIM: Whether operative procedure is a risk factor influencing recurrence following resection of carcinoma in the head ofpancreas or not remains controversies. In this text we compared the recurrence rate of two operative procedure: the Whipple procedure and extended radical operation, and inquired into the factors influencing recurrence after radical resection.METHODS: From January 1995 to December 1998, 35 cases of carcinoma of pancreas underwent the Whipple operadure, 21 patients received the Extended radical operation. All patients were followed up for more than 3 years. Prognostic factors included operative procedure, size of tumor, lymph node, interstitial invasion. RESULTS: Deaths duo to recurrence within 3 years after operation were studied. The death rate was 51.4% in the Whipple procedure and 42.9% in the Extended radical operative procedure. There was a significant difference between the two groups. Recurrence occurred in 75% patients with tumor large than 4 cm, in 87.5% patients with lymph node involvement, and in 50% patients with the presence of interstitial invasion. CONCLUSION: Tumor exceeding 4 cm, lymph node involvement, and presence of interstitial invasion are high risk factors of recurrence after Whipple's procedure and extended radical operation.

    AIM: To evaluate the presence of extracapsular invasion (ECI) in positive nodes as a predictor of disease recur-rence disease in colorectal cancer. METHODS: Two hundred and twenty-eight consecutive patients who underwent colorectal resection were identi-fied for inclusion in this study, of which 46 had positive lymph nodes. Among 46 cases with stage Ⅲcolorectal cancer, 16 had ECI at positive nodes and 8 had disease recurrence. The clinical and pathological features of these cases were reviewed.RESULTS: In the univariate analysis, the number of positive lymph nodes and depth of tumor invasion were significantly associated with the presence of ECI at posi-tive nodes. Multivariate analysis demonstrated that only ECI was a predictor of recurrence. The recurrence-free interval differed significantly among patients with ECI at positive nodes. CONCLUSION: Our results suggest that ECI at meta-static nodes can identify which cases are at high risk of short-term disease recurrence in colorectal cancer.

  10. Risk factors for recurrence after conservative treatment in early breast cancer; Preliminary report

    International Nuclear Information System (INIS)

    To evaluate our experience in the breast-conserving treatment for early breast cancer with special regard to recurrence pattern and related risk factors. Two hundred and sixteen patients with AJC stage I and II beast cancer who received breast conserving treatment between January 1991 and December 1994 were evaluated. Age distribution ranged from 23-80 year old with a median age of 44. One hundred and seventeen patients had T1 lesions and 99 patients had T2 lesions. Axillary lymph nodes were involved in 73 patients. All patients received a breast conserving surgery (wide excision to quadrantectomy) and axillary node dissection followed by radiotherapy. Ninety six patients received chemotherapy before or after radiotherapy. During the follow-up period (3-60 months, median 30 months), local recurrence were noted in six patients (true; 3, elsewhere; 1, skin; 2). Sixteen patients developed distant metastases as the first sign of recurrence at 8-38 months (median 20 months) after surgery. Among them, three patients simultaneously developed local recurrence with distant metastases. Contralateral breast cancer developed in one patient and non-mammary cancers developed in three patients. The actuarial 5 year survival rate was 88.4% (stage I: 96.7%, stage IIa: 95.2%, stage IIb 69.9%). Age, T stage, number of involved axillary lymph nodes, and AJC stage were risk factors for distant metastases in univariate analysis. In the multivariate analysis, the number of involved axillary lymph nodes was the most significant risk factor for metastases. Local recurrence was not common in the early years after radiotherapy. Distant metastases occurred at a steady rate during the first three years and was more common in the patients with larger tumors, higher number of involved axillary nodes, and younger age. (author)

    The HOXB13 p.G84E mutation has been firmly established as a prostate cancer susceptibility allele. Although HOXB13 also plays a role in breast tumor progression, the association of HOXB13 p.G84E with breast cancer risk is less evident. Therefore, we comprehensively interrogated the entire HOXB13 coding sequence for mutations in 1,250 non-BRCA1/2 familial breast cancer cases and 800 controls. We identified two predicted deleterious missense mutations, p.G84E and p.R217C, that were recurrent among breast cancer cases and further evaluated their association with breast cancer risk in a larger study. Taken together, 4,520 familial non-BRCA1/2 breast cancer cases and 3,127 controls were genotyped including the cases and controls of the whole gene screen. The concordance rate for the genotyping assays compared with Sanger sequencing was 100%. The prostate cancer risk allele p.G84E was identified in 18 (0.56%) of 3,187 cases and 16 (0.70%) of 2,300 controls (OR = 0.81, 95% CI = 0.41-1.59, P = 0.54). Additionally, p.R217C was identified in 10 (0.31%) of 3,208 cases and 2 (0.087%) of 2,288 controls (OR = 3.57, 95% CI = 0.76-33.57, P = 0.14). These results imply that none of the recurrent HOXB13 mutations in the Dutch population are associated with breast cancer risk, although it may be worthwhile to evaluate p.R217C in a larger study.

    The roles of fruits and vegetables in colorectal cancer development are unclear. Few prospective studies have assessed the association with adenoma, a known precursor to colorectal cancer. Our aim was to evaluate the association between fruit and vegetable intake and colorectal cancer development by evaluating the risk of incident and recurrent colorectal adenoma and colorectal cancer. Study participants were identified from the intervention arm of the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Fruit and vegetable intake was measured using a self-reported dietary questionnaire. Total fruit and vegetable intake was not associated with reduced incident or recurrent adenoma risk overall, but a protective association was observed for multiple adenomas (Odds ratio 3rd tertile vs. 1st tertile = 0.61, 95% confidence interval (CI): 0.38, 1.00). Higher fruit and vegetable intakes were associated with a borderline reduced risk of colorectal cancer (Hazard ratio (HR) 3rd tertile vs. 1st tertile = 0.82, 95% CI: 0.67, 1.01), which reached significance amongst individuals with high processed meat intakes (HR = 0.74, 95% CI: 0.55, 0.99). Our results suggest that increased fruit and vegetable intake may protect against multiple adenoma development and may reduce the detrimental effects of high processed meat intakes on colorectal cancer risk.

  15. Local recurrences after breast-conserving treatments in breast cancer: risk factors and effect on survival

    International Nuclear Information System (INIS)

    To determine the risk factors for local and distant failure in node-negative breast cancer treated with breast-conservative surgery and radiotherapy and to determine the relationship between these two events. We retrospectively selected 908 patients who received conservative surgery and radiotherapy but no chemotherapy between 1980 and 1995, for a mode-negative breast cancer. Patients were divided in two groups according to the status of the margins of resection. All pathology specimens were reviewed. In case of negative margins, the risk factors for local recurrences picked up by the Cox model were histologic multi-focus (P=0.0076), peritumoral vessel invasion (P=0.021) and age ≥40 years (P=0.024), and in case of involved margins, negative oestrogen receptors (P=0.0012), histologic multi-focus (P=0.0028), and absence of hormonal therapy (P=0.017). The 10-year local recurrence rate was 18 % in case of negative margins and 29 % in case of involved margins, although in the latter case patients received high-dose adjuvant radiotherapy. Accordingly, the 10-year distant failure rates were 16 % and 27 %, respectively. Many arguments suggest that local and distant failures are closely related. Patients with histologic multi-focus or positive margins are at high risk of local failure and then of distant failure, and require a more aggressive initial treatment. (author)

Methods: We analyzed 1,106 women who were diagnosed with stage 0­–3 breast cancer between 2007 and 2011 and experienced remission after surgery and adjuvant therapy. The patients were divided into two groups: group A (n=996, in which patients did not participate in any MLD therapy, regardless of whether they developed breast cancer-related lymphedema (BCRL after cancer treatment; and group B (n=110, in which patients participated in MLD therapy for BCRL. All patients were monitored until October 2013 to determine whether breast cancer recurrence developed, including local or regional recurrence and distant metastasis. Patients who developed cancer recurrence prior to MLD therapy were excluded from analysis. Risk factors associated with cancer recurrence were evaluated using Cox proportional hazards models. Results: During the monitoring period, 166 patients (15.0% developed cancer recurrence, including 154 (15.5% in group A and 12 (10.9% in group B. The median period from surgery to cancer recurrence was 1.85 (interquartile range 1.18–2.93 years. Independent risk factors for cancer recurrence were tumor histological grading of grade 3, high number (≥3 of axillary lymph node invasion, and a large tumor size (>5 cm. Factors

    Full Text Available Background: Postoperative preablative stimulated thyroglobulin (ps-Tg has been evaluated in predicting prognosis and success of ablation regarding differentiated thyroid cancer (DTC; however, its relationship with recurrence risk and radioiodine decision-making remains uncertain, especially in Chinese DTC patients. We aimed to evaluate the association between ps-Tg and recurrence risk stratification in DTC, to provide incremental values for ps-Tg in postoperative assessment and radioiodine management. Methods: Seven hundred and seven patients with DTC were included; low-risk (L; n = 90, intermediate-risk (I; n = 283, and high-risk (H; n = 334, 117 with distant metastasis [M1] patients were divided according to recurrence risk stratification. The M1 group was further analyzed regarding evidence of metastasis. Cut-off values of ps-Tg were obtained using receiver operating characteristic analysis. Results: Patients with more advanced disease at initial risk stratification were more likely to have higher ps-Tg levels (I vs. L: P < 0.05; H vs. I: P < 0.001; H vs. L: P < 0.001. The corresponding cut-off value of ps-Tg for distinguishing sensitivity and specificity in each of the two groups was 2.95 ng/ml (I vs. L: 61.5%, 63.3%, 29.5 ng/ml (H vs. I: 41.9%, 92.6%, 47.1 ng/ml (M1 vs. M0 in the H group: 79.5%, 88.9% and 47.1 ng/ml (M1 vs. M0 in all patients: 79.5%, 93.7%. With the cut-off value at 47.1 ng/ml, ps-Tg was the only factor that could be used to identify distant metastases, and consequently if measured before radioiodine therapy would prevent 10.26% of patients with M1 from undertreatment. Conclusions: Ps-Tg, as an ongoing reassessment marker, favors differential recurrence risk grading and provides incremental values for radioiodine treatment decision-making.

  19. Stroke patients with a past history of cancer are at increased risk of recurrent stroke and cardiovascular mortality.

    Full Text Available BACKGROUND AND PURPOSE: Cancer patients are at increased risk of cardiovascular and cerebrovascular events. It is unclear whether cancer confers any additional risk for recurrent stroke or cardiovascular mortality after stroke. METHODS: This was a single center, observational study of 1,105 consecutive Chinese ischemic stroke patients recruited from a large stroke rehabilitation unit based in Hong Kong. We sought to determine whether patients with cancer are at higher risk of recurrent stroke and cardiovascular mortality. RESULTS: Amongst 1,105 patients, 58 patients (5.2% had cancer, of whom 74% were in remission. After a mean follow-up of 76 ± 18 months, 241 patients developed a recurrent stroke: 22 in patients with cancer (38%, annual incidence 13.94%/year, substantially more than those without cancer (21%, 4.65%/year (p<0.01. In a Cox regression model, cancer, age and atrial fibrillation were the 3 independent predictors of recurrent stroke with a hazard ratio (HR of 2.42 (95% confidence interval (CI: 1.54-3.80, 1.01 (1.00-1.03 and 1.35 (1.01-1.82 respectively. Likewise, patients with cancer had a higher cardiovascular mortality compared with those without cancer (4.30%/year vs. 2.35%/year, p = 0.08. In Cox regression analysis, cancer (HR: 2.08, 95% CI: 1.08-4.02, age (HR: 1.04, 95% CI 1.02-1.06, heart failure (HR: 3.06, 95% CI 1.72-5.47 and significant carotid atherosclerosis (HR: 1.55, 95% CI 1.02-2.36 were independent predictors for cardiovascular mortality. CONCLUSIONS: Stroke patients with a past history of cancer are at increased risk of recurrent stroke and cardiovascular mortality.

  20. Differentiated thyroid cancer: reclassification of the risk of recurrence based on the response to initial treatment

    International Nuclear Information System (INIS)

    Introduction: differentiated thyroid cancer (DTC) is the most frequent endocrine tumor generally showing a favourable outcome. The American Thyroid Association (ATA) classification system is not only useful to assess the risk of recurrence but also guides tumor follow-up. However, this system shows a static image of the patient at the beginning of treatment based on clinical and pathological features, and it has not been designed to be modified along the clinical course of disease. Therefore, the Memorial Sloan-Kettering Cancer Center (MS-KCC) has designed a reclassification system after 2 years of the initial treatment (IT) thus providing a dynamic perspective of each patient. Objective: to report our experience with the MS-KCC risk of recurrence reclassification system on DTC patients. Materials and methods: retrospective observational descriptive study of the results of the reclassification system of the DCT patients after two years of IT with surgery and radioiodine ablation, between October 2004 and April 2011. Data was obtained by reviewing the charts of patients. All surgeries, laboratory determinations and nuclear medicine procedures took place at our Hospital. Patients were classified according to initial risk of recurrence based on the ATA system and they were reclassified following the system proposed by the MS-KCC 2 years after IT. Patients with antithyroglobulin antibodies > 12 IU/ml were excluded due to interference with thyroglobulin determination. Results: we reviewed data of 31 patients diagnosed with DTC. They were classified according to the ATA system as: low risk 17 (54.8 %), intermediate risk 13 (42 %) and high risk 1 (3.2 %) and they were reclassified following the MS-KCC system as having: excellent response 25 (80.6 %), acceptable response 6 (19.4 %) and incomplete response 0 (0 %). An excellent response was observed in 14 (82.4 %) and an acceptable response was observed in 3 (17.6 %) of the low-risk classified patients; an excellent

  1. Maximum vs. Mono Androgen Blockade and the Risk of Recurrence in Men With Localized Prostate Cancer Undergoing Brachytherapy

    International Nuclear Information System (INIS)

    Purpose: We examined whether maximum androgen blockade (MAB) is associated with a decreased recurrence risk vs. single-agent androgen suppression (monotherapy) for men undergoing brachytherapy (BT) for localized prostate cancer. Methods and Materials: Data from 223 men in Cancer of the Prostate Strategic Urologic Research Endeavor database who received androgen deprivation therapy (ADT) concurrent with BT for intermediate- or high-risk prostatic adenocarcinoma were included; 159 (71%) received MAB, and 64 (29%) monotherapy (luteinizing hormone-releasing hormone agonist or anti-androgen alone). Cox regression analysis was performed to assess whether the choice of ADT was associated with disease recurrence adjusting for known prognostic factors. Results: Men who received MAB had similar Gleason scores, T categories, and pretreatment prostate-specific antigen as those who received monotherapy. After a median follow-up of 49 months, the use of MAB was not associated with a decrease in the risk recurrence (p = 0.72), after adjusting for known prognostic factors. A higher PSA at diagnosis (p = 0.03) and younger age at diagnosis (p < 0.01) were associated with increased recurrence risk. The 3-year recurrence free survival was 76% for patients in both monotherapy and MAB groups. Conclusions: There are varied practice patterns in physicians' choice of the extent of concurrent ADT when used with brachytherapy for men with intermediate- or high-risk prostate cancer. Given a lack of demonstrated superiority from either ADT choice, both appear to be reasonable options.

  6. Co-occurring gland angularity in localized subgraphs: predicting biochemical recurrence in intermediate-risk prostate cancer patients.

    Directory of Open Access Journals (Sweden)

    George Lee

    Full Text Available Quantitative histomorphometry (QH refers to the application of advanced computational image analysis to reproducibly describe disease appearance on digitized histopathology images. QH thus could serve as an important complementary tool for pathologists in interrogating and interpreting cancer morphology and malignancy. In the US, annually, over 60,000 prostate cancer patients undergo radical prostatectomy treatment. Around 10,000 of these men experience biochemical recurrence within 5 years of surgery, a marker for local or distant disease recurrence. The ability to predict the risk of biochemical recurrence soon after surgery could allow for adjuvant therapies to be prescribed as necessary to improve long term treatment outcomes. The underlying hypothesis with our approach, co-occurring gland angularity (CGA, is that in benign or less aggressive prostate cancer, gland orientations within local neighborhoods are similar to each other but are more chaotically arranged in aggressive disease. By modeling the extent of the disorder, we can differentiate surgically removed prostate tissue sections from (a benign and malignant regions and (b more and less aggressive prostate cancer. For a cohort of 40 intermediate-risk (mostly Gleason sum 7 surgically cured prostate cancer patients where half suffered biochemical recurrence, the CGA features were able to predict biochemical recurrence with 73% accuracy. Additionally, for 80 regions of interest chosen from the 40 studies, corresponding to both normal and cancerous cases, the CGA features yielded a 99% accuracy. CGAs were shown to be statistically signicantly ([Formula: see text] better at predicting BCR compared to state-of-the-art QH methods and postoperative prostate cancer nomograms.

  10. Predicting the Risk of Venous Thromboembolism Recurrence

    OpenAIRE

    2012-01-01

    Venous thromboembolism (VTE) is a chronic disease with a 30% ten-year recurrence rate. The highest incidence of recurrence is in the first 6 months. Active cancer significantly increases the hazard of early recurrence, and the proportions of time on standard heparin (APTT≥0.2 anti-Xa U/mL) and warfarin (INR≥2.0) treatment, significantly reduce the hazard. The acute treatment duration does not affect recurrence risk after treatment is stopped. Independent predictors of late recurrence include ...

  11. Functional polymorphisms in the matrix metalloproteinase genes and their association with bladder cancer risk and recurrence: a mini-review.

    Molecular pathogenesis of muscle invasive bladder cancer and non-muscle invasive bladder cancer is incompletely elucidated. It is believed that matrix metalloproteinases, which are involved in the processes of uncontrolled extracellular matrix substrates degradation and participate in modulating the activity of a variety of non-matrix proteins, can contribute to carcinogenesis. Polymorphisms in the MMP genes associated with unique genomic changes in bladder cancer patients are still being investigated to discover direct links with pathophysiological mechanisms. Because of the functional polymorphisms in the MMP genes, which have a proven or likely effect on their protein expression, they could possibly affect the tumor process. The current mini-review synthesizes findings regarding the association of genetic polymorphisms in the MMP genes with bladder cancer risk and recurrence in patients. We discuss the current views on the feasibility of genetic polymorphisms in the MMP1, 2, 3, 7, 8, 9 and 12 genes as a risk, and prognostic markers for patients with bladder cancer. The majority of the research described in the present mini-review proves that the genetic polymorphism in the MMP1 (rs1799750) is the most widely studied, and suggests that the rare genotype, 2G2G, of that gene might show increased susceptibility for bladder cancer, especially among smokers. However, existing statistically significant associations between the genetic polymorphisms in the MMP genes and bladder cancer risk have not been clearly shown, and further studies are necessary in order to positively confirm them or dispel potential false hopes.

  12. Beyond D’Amico risk classes for predicting recurrence after external beam radiotherapy for prostate cancer: the Candiolo classifier

    International Nuclear Information System (INIS)

    The aim of this work is to develop an algorithm to predict recurrence in prostate cancer patients treated with radical radiotherapy, getting up to a prognostic power higher than traditional D’Amico risk classification. Two thousand four hundred ninety-three men belonging to the EUREKA-2 retrospective multi-centric database on prostate cancer and treated with external-beam radiotherapy as primary treatment comprised the study population. A Cox regression time to PSA failure analysis was performed in univariate and multivariate settings, evaluating the predictive ability of age, pre-treatment PSA, clinical-radiological staging, Gleason score and percentage of positive cores at biopsy (%PC). The accuracy of this model was checked with bootstrapping statistics. Subgroups for all the variables’ combinations were combined to classify patients into five different “Candiolo” risk-classes for biochemical Progression Free Survival (bPFS); thereafter, they were also applied to clinical PFS (cPFS), systemic PFS (sPFS) and Prostate Cancer Specific Survival (PCSS), and compared to D’Amico risk grouping performances. The Candiolo classifier splits patients in 5 risk-groups with the following 10-years bPFS, cPFS, sPFS and PCSS: for very-low-risk 90 %, 94 %, 100 % and 100 %; for low-risk 74 %, 88 %, 94 % and 98 %; for intermediate-risk 60 %, 82 %, 91 % and 92 %; for high-risk 43 %, 55 %, 80 % and 89 % and for very-high-risk 14 %, 38 %, 56 % and 70 %. Our classifier outperforms D’Amico risk classes for all the end-points evaluated, with concordance indexes of 71.5 %, 75.5 %, 80 % and 80.5 % versus 63 %, 65.5 %, 69.5 % and 69 %, respectively. Our classification tool, combining five clinical and easily available parameters, seems to better stratify patients in predicting prostate cancer recurrence after radiotherapy compared to the traditional D’Amico risk classes.

    Rectal cancer represents about 30% of colorectal cancers, being around 50% locally advanced at presentation. Chemoradiation (CRT) followed by total mesorectal excision is the standard of care for these locally advanced stages. However, it is not free of adverse effects and toxicity and the complete pathologic response rate is between 10% and 30%. This makes it extremely important to define factors that can predict response to this therapy. Focal adhesion kinase (FAK) expression has been correlated with worse prognosis in several tumours and its possible involvement in cancer radio- and chemosensitivity has been suggested; however, its role in rectal cancer has not been analysed yet. To analyse the association of FAK expression with tumour response to CRT in locally advanced rectal cancer. This study includes 73 patients with locally advanced rectal cancer receiving standard neoadjuvant CRT followed by total mesorectal excision. Focal adhesion kinase protein levels were immunohistochemically analysed in the pre-treatment biopsies of these patients and correlated with tumour response to CRT and patients survival. Low FAK expression was significantly correlated with local and distant recurrence (P = 0.013). Low FAK expression was found to be a predictive marker of tumour response to neoadjuvant therapy (P = 0.007) and patients whose tumours did not express FAK showed a strong association with lower disease-free survival (P = 0.01). Focal adhesion kinase expression predicts neoadjuvant CRT response in rectal cancer patients and it is a clinically relevant risk factor for local and distant recurrence. PMID:27171907

  14. Recurrent genomic gains in preinvasive lesions as a biomarker of risk for lung cancer.

    Directory of Open Access Journals (Sweden)

    Pierre P Massion

    Full Text Available Lung carcinoma development is accompanied by field changes that may have diagnostic significance. We have previously shown the importance of chromosomal aneusomy in lung cancer progression. Here, we tested whether genomic gains in six specific loci, TP63 on 3q28, EGFR on 7p12, MYC on 8q24, 5p15.2, and centromeric regions for chromosomes 3 (CEP3 and 6 (CEP6, may provide further value in the prediction of lung cancer. Bronchial biopsy specimens were obtained by LIFE bronchoscopy from 70 subjects (27 with prevalent lung cancers and 43 individuals without lung cancer. Twenty six biopsies were read as moderate dysplasia, 21 as severe dysplasia and 23 as carcinoma in situ (CIS. Four-micron paraffin sections were submitted to a 4-target FISH assay (LAVysion, Abbott Molecular and reprobed for TP63 and CEP 3 sequences. Spot counts were obtained in 30-50 nuclei per specimen for each probe. Increased gene copy number in 4 of the 6 probes was associated with increased risk of being diagnosed with lung cancer both in unadjusted analyses (odds ratio = 11, p<0.05 and adjusted for histology grade (odds ratio = 17, p<0.05. The most informative 4 probes were TP63, MYC, CEP3 and CEP6. The combination of these 4 probes offered a sensitivity of 82% for lung cancer and a specificity of 58%. These results indicate that specific cytogenetic alterations present in preinvasive lung lesions are closely associated with the diagnosis of lung cancer and may therefore have value in assessing lung cancer risk.

    Deregulation of long non-coding RNAs (lncRNAs) expression has been proven to be involved in the development and progression of cancer. However, expression pattern and prognostic value of lncRNAs in breast cancer recurrence remain unclear. Here, we analyzed lncRNA expression profiles of breast cancer patients who did or did not develop recurrence by repurposing existing microarray datasets from the Gene Expression Omnibus database, and identified 12 differentially expressed lncRNAs that were closely associated with tumor recurrence of breast cancer patients. We constructed a lncRNA-focus molecular signature by the risk scoring method based on the expression levels of 12 relapse-related lncRNAs from the discovery cohort, which classified patients into high-risk and low-risk groups with significantly different recurrence-free survival (HR = 2.72, 95% confidence interval 2.07-3.57; p = 4.8e-13). The 12-lncRNA signature also represented similar prognostic value in two out of three independent validation cohorts. Furthermore, the prognostic power of the 12-lncRNA signature was independent of known clinical prognostic factors in at least two cohorts. Functional analysis suggested that the predicted relapse-related lncRNAs may be involved in known breast cancer-related biological processes and pathways. Our results highlighted the potential of lncRNAs as novel candidate biomarkers to identify breast cancer patients at high risk of tumor recurrence. PMID:27503456

    1990-01-01

    This descriptive study of the perceptions and needs of people with recurrent malignancies asks three questions: How do patients describe the meaning of a recurrence of cancer? Do individuals perceive the diagnosis of recurrence and the initial diagnosis of cancer differently? What are the key psychosocial problems associated with recurrent cancer? The theoretical framework was based on Lazarus and Folkman's theory of stress, appraisal, and coping. Subjects completed the Impact of Event Scale (IES), the Psychosocial Adjustment to Illness Scale--Self-Report (PAIS), and a semistructured qualitative interview. The interview elicited perceptions of the event of recurrence and differences between the diagnosis of recurrence and the initial diagnosis. The convenience sample included 40 patients diagnosed with recurrent cancer within the last 30 days. Many subjects (78%) reported that the recurrence was more upsetting than the initial diagnosis. Scores on both the IES and the PAIS were high when compared to normative samples of patients with cancer suggesting that this sample of patients experienced a lot of psychological distress as well as problems at home, work, and in their social lives. These concerns often were unknown to caregivers. Although more research is needed, the authors propose that, with more accurate assessment, more effective intervention could be implemented and the quality of life improved for patients with recurrent cancer.

  18. Follicular thyroid cancer in children and adolescents. Clinicopathologic features, long-term survival, and risk factors for recurrence

    International Nuclear Information System (INIS)

    Children and adolescents represent 1-1.5% of all patients with thyroid cancer (TC). The vast majority of TC in children and adolescents is papillary TC; follicular TC (FTC) is exceedingly rare. In this study, we evaluate the clinical and pathological features of FTC in children and adolescents. We also report the risk factors for post-operative tumor recurrence and the associated outcomes. Twenty children and adolescents (under 21 years old) with FTC have been treated and followed at Noguchi Thyroid Clinic and Hospital Foundation since 1946. All patients underwent surgery (lobectomy, 11; subtotal thyroidectomy, 8; and total thyroidectomy, 1), and 8 patients received postoperative external beam radiation therapy. The incidence of FTC in children and adolescents was 1.9% among all FTC patients treated in our hospital. Histopathology revealed vascular and capsular invasion in 9 and 20 patients, respectively. The tumor recurrence rate in FTC with vascular invasion is significantly higher than in those without it (p=0.038). No other factors were significant. Patients with recurrences were treated with completion thyroidectomy and 131I radioactive iodine therapy. There were no significant differences in the rates of disease-free survival or cause-specific survival when pediatric/adolescent FTC patients were compared to adults with FTC. FTC is very rare among children and adolescents, but the outcomes are similar to those observed among adults. Vascular invasion is poor prognostic indicator in pediatric/adolescent FTC patients.

    Purpose: To assess, in a retrospective cohort study, rates and predictors of first and recurrent stroke in patients treated with cranial irradiation (CRT) and/or cervical irradiation at ≤18 years of age. Methods and Materials: We performed chart abstraction (n=383) and phone interviews (n=104) to measure first and recurrent stroke in 383 patients who received CRT and/or cervical radiation at a single institution between 1980 and 2009. Stroke was defined as a physician diagnosis and symptoms consistent with stroke. Incidence of first stroke was number of first strokes per person-years of observation after radiation. We used survival analysis techniques to determine cumulative incidence of first and recurrent stroke. Results: Among 325 subjects with sufficient follow-up data, we identified 19 first strokes (13 ischemic, 4 hemorrhagic, 2 unknown subtype) occurring at a median age of 24 years (interquartile range 17-33 years) in patients treated with CRT. Imaging was reviewed when available (n=13), and the stroke was confirmed in 12. Overall rate of first stroke was 625 (95% confidence interval [CI] 378-977) per 100,000 person-years. The cumulative incidence of first stroke was 2% (95% CI 0.01%-5.3%) at 5 years and 4% (95% CI 2.0%-8.4%) at 10 years after irradiation. With each 100-cGy increase in the radiation dose, the stroke hazard increased by 5% (hazard ratio 1.05; 95% CI 1.01-1.09; P=.02). We identified 6 recurrent strokes; 5 had available imaging that confirmed the stroke. Median time to recurrence was 15 months (interquartile range 6 months-3.2 years) after first stroke. The cumulative incidence of recurrent stroke was 38% (95% CI 17%-69%) at 5 years and 59% (95% CI 27%-92%) at 10 years after first stroke. Conclusion: Cranial irradiation puts childhood cancer survivors at high risk of both first and recurrent stroke. Stroke prevention strategies for these survivors are needed.

    Purpose: To compare the locoregional recurrence (LRR) rates in patients with nodal mirometastases (pNmic) with those in patients with node-negative (pN0) and macroscopic node-positive (pNmac) breast cancer; and to evaluate the LRR rates according to locoregional treatment of pNmic disease. Methods and Materials: The subjects were 9,616 women diagnosed between 1989 and 1999 with Stage pT1-T2, pN0, pNmic, or pNmac, M0 breast cancer. All women had undergone axillary dissection. The Kaplan-Meier local recurrence, regional recurrence, and LRR rates were compared among those with pN0 (n = 7,977), pNmic (n = 490) and pNmac (n = 1,149) and according to locoregional treatment. Multivariate analysis was performed to identify the significant factors associated with LRR. Results: The median follow-up was 11 years. The 10-year Kaplan-Meier recurrence rate in the pN0, pNmic, and pNmac cohorts was 6.1%, 6.8%, and 8.7% for local recurrence; 3.1%, 6.2%, and 10.3% for regional recurrence; and 8.0%, 11.6%, and 15.2% for LRR, respectively (all p < .001). In the pNmic patients, the 10-year regional recurrence rate was 6.4% with breast-conserving surgery plus breast radiotherapy (RT), 5.4% with breast-conserving surgery plus locoregional RT, 4.6% with mastectomy alone, 11.1% with mastectomy plus chest wall RT, and 10.7% with mastectomy plus locoregional RT. In patients with pNmic disease and age <45 years, Grade 3 histologic features, lymphovascular invasion, nodal ratio >0.25, and estrogen receptor-negative disease, the 10-year LRR rates were 15-20%. On multivariate analysis of the entire cohort, pNmic was associated with greater LRR than Stage pN0 (hazard ratio [HR], 1.6; p = .002). On multivariate analysis of pNmic patients only, age <45 years was associated with significantly greater LRR (HR, 1.9; p = .03), and trends for greater LRR were observed with a nodal ratio >0.25 (HR, 2.0; p = .07) and lymphovascular invasion (HR, 1.7; p = .07). Conclusion: Women with pNmic had a greater

  3. Patient subsets with T1-T2, node-negative breast cancer at high locoregional recurrence risk after mastectomy

    International Nuclear Information System (INIS)

    Purpose: To identify patient subsets with T1-T2N0 breast cancer at high risk of locoregional recurrence (LRR) who may warrant consideration for postmastectomy radiotherapy. Methods and Materials: Data were analyzed for 1505 women referred between 1989 and 1999 with pathologic T1-T2N0M0 breast cancer treated with mastectomy with clear margins and no adjuvant radiotherapy. Logistic regression analysis was performed to identify statistically significant factors associated with LRR. Recursive partitioning was used to develop a classification tree model for LRR given the prognostic variables. Results: The median follow-up was 7.0 years. The 10-year Kaplan-Meier LRR rate was 7.8%. On logistic regression analysis, the statistically significant factors predicting LRR were histologic grade (p <0.0001), lymphovascular invasion (LVI) (p <0.0001), T stage (p = 0.05), and systemic therapy use (p = 0.01). In the recursive partitioning model, the first split in the classification tree was histologic grade. For 972 patients without high-grade histologic features, the 10-year Kaplan-Meier LRR rate was 5.5%. For 533 patients with Grade 3 disease (LRR rate 12.1%), the concomitant presence of LVI was associated with a LRR rate of 21.2% (n = 126). In patients with Grade 3 disease without LVI, T2 tumors conferred a LRR rate of 13.4% (n = 194), which increased to 23.2% for patients who did not receive systemic therapy (n = 63). Conclusion: Women with pT1-T2N0 breast cancer experienced a LRR risk of approximately 20% in the presence of Grade 3 disease with LVI or Grade 3 disease, T2 tumors, and no systemic therapy. These subsets of node-negative patients warrant consideration of for postmastectomy radiotherapy

    Full Text Available BACKGROUND: Rectal washout can prevent local recurrence after anterior resection of rectal cancer. Few studies have focused particularly on the association between irrigation fluids volume or agents and the risk of local recurrence after anterior resection of rectal cancer. OBJECTIVE: To estimate the association between irrigation fluids types, volumes of rectal washout and risk of local recurrence after anterior resection for cancer. DATA SOURCES: Relevant studies were identified by a search of Medline, Embase, Wiley Online Library, China National Knowledge Infrastructure, Cochrane Oral Health Group Specialized Register, Wanfang databases and Google Website from their inception until October 18,2013. STUDY SELECTION: Studies reporting the association between rectal washout types and volumes and risk of local recurrence after anterior resection for cancer were included. INTERVENTIONS: Eligible studies used rectal washout. Control groups were defined as no washout. STUDY APPRAISAL AND SYNTHESIS METHODS: Random-effects model were used to obtain summary estimates of RR and 95% CI, with Stata version 11 and RevMan 5.2.5 softwares used. The quality of report was appraised in reference to the MINORS item. RESULTS: Of the 919 rectal cancer patients in 8 included studies, a total of 61(6.64% cases of local recurrence were reported, with a pooled RR 0.51 (95%CI = 0.28-0.92, P = 0.03. The RRs 0.37 and 0.39 in normal saline and washout volume (≥ 1500 ml normal saline subgroup, respectively, indicated that rectal washout with normal saline, or ≥ 1500 ml in volume could significantly reduce local recurrence (LR rate (95% CI = 0.17-0.79, P = 0.01; 95% CI = 0.18-0.87, P = 0.02 after anterior resection for cancer.

  5. Locoregional recurrence risk factors in breast cancer patients with positive axillary lymph nodes and the impact of postmastectomy radiotherapy

    International Nuclear Information System (INIS)

    Locoregional recurrence (LRR) after mastectomy reduces the patient's quality of life and survival. There is a consensus that postmastectomy radiotherapy (PMRT) helps establish locoregional control and reduces LRR in patients with ≥4 metastatic nodes. However, in patients with 1-3 metastatic nodes, the incidence of LRR and the role of PMRT have been the subject of substantial controversy. This study assessed the risk factors for LRR and the efficacy of PMRT in Japanese breast cancer patients with metastatic nodes. This study analyzed 789 cases of invasive breast carcinoma with metastatic nodes from 1998 to 2008. We divided the study population into 4 groups: 1-3 positive nodes with/without chemotherapy and ≥4 positive nodes with/without chemotherapy. Risk factors for LRR were identified and the relationship between LRR and PMRT was analyzed. During the median follow-up of 59.6 months, 61 (7.7%) patients experienced LRR. In patients who received chemotherapy, independent LRR risk factors were high nuclear grade, severe lymphatic invasion, vascular invasion, and progesterone receptor-negative status in patients with 1-3 positive nodes, and severe lymphatic invasion and estrogen receptor-negative status in patients with ≥4 nodes. Although patients treated with PMRT had good outcomes, there was no significant difference, and PMRT did not significantly improve the outcome of the patients with all risk factors. With systemic therapy and adequate dissection, PMRT by itself was of limited value in establishing locoregional control. The indication for PMRT in patients with 1-3 positive nodes remains controversial. (author)

    Full Text Available Patients with non-muscle invasive bladder cancer (NMIBC generally have a high risk of relapsing locally after primary tumor resection. The search for new predictive markers of local recurrence thus represents an important goal for the management of this disease. We studied the copy number variations (CNVs of 24 oncogenes (MDM4, MYCN, ALK, PDGFRA, KIT, KDR, DHFR, EGFR, MET, SMO, FGFR1, MYC, ABL1, RET, CCND1, CCND2, CDK4, MDM2, AURKB, ERBB2, TOP2A, AURKA, AR and BRAF using multiplex ligation probe amplification technique to verify their role as predictive markers of recurrence. Formalin-fixed paraffin-embedded tissue samples from 43 patients who underwent transurethral resection of the bladder (TURB were used; 23 patients had relapsed and 20 were disease-free after 5 years. Amplification frequencies were analyzed for all genes and MDM4 was the only gene that showed significantly higher amplification in non recurrent patients than in recurrent ones (0.65 vs. 0.3; Fisher’s test p = 0.023. Recurrence-free survival analysis confirmed the predictive role of MDM4 (log-rank test p = 0.041. Our preliminary results indicate a putative role for the MDM4 gene in predicting local recurrence of bladder cancer. Confirmation of this hypothesis is needed in a larger cohort of NMIBC patients.

    Full Text Available The indications for post-mastectomy radiotherapy (PMRT with T1-2 breast cancer and 1-3 positive axillary lymph nodes is still controversial. The purpose of this study was to investigate the role of PMRT in T1-2 breast cancer with 1-3 positive axillary lymph node.We retrospectively reviewed the file records of 79 patients receiving PMRT and not receiving PMRT (618 patients.The median follow-up was 65 months. Multivariate analysis showed that PMRT was an independent prognostic factor of locoregional recurrence-free survival (LRFS (P = 0.010. Subgroup analysis of patients who did not undergo PMRT showed that pT stage, number of positive axillary lymph nodes, and molecular subtype were independent prognostic factors of LRFS. PMRT improved LRFS in the entire group (P = 0.005, but did not affect distant metastasis-free survival (DMFS (P = 0.494, disease-free survival (DFS (P = 0.215, and overall survival (OS (P = 0.645. For patients without PMRT, the 5-year LRFS of low-risk patients (0-1 risk factor for locoregional recurrence of 94.5% was significantly higher than that of high-risk patients (2-3 risk factors for locoregional recurrence (80.9%, P < 0.001. PMRT improved LRFS (P = 0.001 and DFS (P = 0.027 in high-risk patients, but did not improve LRFS, DMFS, DFS, and OS in low-risk patients.PMRT is beneficial in patients with high risk of locoregional recurrence breast cancer patients with T1-2 and 1 to 3 positive nodes.

  8. Impact of glutathione-S-transferases (GST polymorphisms and hypermethylation of relevant genes on risk of prostate cancer biochemical recurrence: a meta-analysis.

    Rui Chen

    Full Text Available INTRODUCTION: Accurate prediction of the biochemical recurrence (BCR is critical for patients after intended curative therapy like radical prostatectomy (RP or definitive radiotherapy for prostate cancer. Glutathione-S-transferases polymorphisms as well as hypermethylation of GSTP1 and functional genes in carcinogenesis, including tumor suppression gene (APC, hormone receptor that regulates cell growth and differentiation gene (RARbeta were reported to be associated with BCR. Nevertheless, the reported results are inconsistent. To evaluate the relationship between glutathione-S-transferases polymorphisms and hypermethylation of these genes and the risk of prostate cancer BCR, we carried out a meta-analysis of the published studies. METHODS AND MATERIALS: We performed a search in Medline, Embase and CNKI database with GST, APC, RARbeta in combination with single nucleotide polymorphism, hypermethylation, prostate cancer and recurrence. Languages were restricted to English and Chinese. RESULTS: Our study included 4 case-control studies and 7 cohort studies including 12 data sets and 3,037 prostate cancer patients. We confirmed that APC hypermethylation is associated with a modest hazard for biochemical recurrence after RP (HR = 1.85, 95%CI = 1.12-3.06. We also suggest GSTP1 polymorphism and CpG hypermethylation tested in serum are associated with BCR (HR = 1.94, 95%CI = 1.13-3.34. We also identified a possible association between GSTM1 null polymorphism and prostate cancer biochemical recurrence risk with borderline significance (HR = 1.29, 95%CI = 0.97-1.71. CONCLUSION: To our knowledge, this is the first meta-analysis evaluating the relationship of polymorphisms and hypermethylation in GSTs and biochemical recurrence. GSTM1, GSTP1 polymorphisms and hypermethylation of GSTP1, APC may be potential biomarkers for the evaluation of the probability of BCR. Further studies are warranted to validate these findings in larger cohorts with longer follow-up.

    Human papillomavirus (HPV) is responsible for increasing incidence of oropharyngeal cancer. At present, there are no biomarkers in the surveillance algorithm for HPV-positive oropharyngeal cancer (HPV-OPC). HPV16 E6 antibody precedes oropharyngeal cancer diagnosis. If HPV16 E6 indeed precedes primary diagnosis, it is similarly expected to precede disease recurrence and may have a potential role as a biomarker for surveillance of HPV-OPC. To determine whether HPV antibody titers have a potential role as early markers of disease recurrence or prognosis, a retrospective pilot study was designed to determine whether HPV16 early antibody titers E6, E7, E1, and E2 decrease after treatment of HPV16-positive OPC. Trends in pretreatment, early (≤6 months after treatment), and late posttreatment (>6 months after treatment) HPV16 antibody titers were examined. There were 43, 34, and 52 subjects with serum samples available for pretreatment, early, and late posttreatment intervals. Mean pretreatment antibody levels were higher than posttreatment antibody levels. Average antibody levels decreased significantly over time for E6 (Ptrend = 0.001) and E7 (Ptrend < 0.001). Six disease recurrences were observed during the follow-up period (median, 4.4 years). In univariate analysis, a log-unit increase in pretreatment E6 titer was significantly associated with increased risk of disease recurrence (HR, 5.42; 95% CI, 1.1-25.7; P = 0.03). Therefore, levels of antibodies to HPV16 early oncoproteins decline after therapy. Higher E6 titers at diagnosis are associated with significant increases in the risk of recurrence. These data support the prospective evaluation of HPV16 antibodies as markers of surveillance and for risk stratification at diagnosis. PMID:26701665

  10. Risk factors for local recurrence after breast-conserving therapy

    International Nuclear Information System (INIS)

    Breast-conserving therapy has been widely accepted as a standard treatment for early breast cancer both in Western countries and in Japan. In Western countries, many studies have investigated the risk factors for local recurrence after breast-conserving therapy (BCT), but few such studies have been done in Japan. To determine the risk factors for local recurrence in 399 breast cancer patients (stage I and II, n=396; stage III, n=3) who had undergone BCT with or without postoperative radiation therapy, we evaluated their clinicopathological features by univariate and multivariate analyses. The patients were treated at Osaka National Hospital between February 1988 and December 1997. Univariate analysis showed that a young age (≤45 years; P=0.0005) was a significant risk factor for local recurrence, while radiation therapy (P=0.0058) and adjuvant endocrine therapy (P=0.0041) significantly reduced the risk of local recurrence. In patients with BCT, without radiation therapy a positive surgical margin significantly increased the risk of local recurrence (P=0.0470). Multivariate analysis showed that a young age (P=0.0285) was a significant independent risk factor for local recurrence, while radiation therapy (P=0.0457) significantly decreased recurrence. In patients with a negative surgical margin, radiation therapy (P=0.0158) and adjuvant endocrine therapy (P=0.0421) significantly reduced the relative risk of local recurrence, to 0.160 and 0.366, respectively. In patients with a positive surgical margin, radiation therapy marginally significantly (P=0.0756) reduced the relative risk of local recurrence, to 0.181, and adjuvant endocrine therapy significantly (P=0.0119) reduced the risk, to 0.076. Young age and lack of radiation therapy or adjuvant endocrine therapy were risk factors for local recurrence in breast cancer patients treated with breast conserving therapy, with surgical margin status also being a possible risk factor.

  11. Role of radiotherapy and prognostic factors in breast cancer patients at high-risk of recurrence treated with modified radical mastectomy and chemotherapy

    International Nuclear Information System (INIS)

    Objective: To analyze the outcome and prognostic factors in breast cancer at high-risk of recurrence and evaluate the role of radiotherapy. Methods: 381 breast cancer patients treated with mastectomy and axillary dissection were retrospectively analyzed. The including criterias were pathologic diagnosis of invasive breast cancer, T3-T4 and/or four or more positive axillary nodes. The survival rates was calculated by Kaplan-Meier method, and compared by Logrank test. Cox regression model was used to select potential prognostic variables. Results: The median follow up was 48 months. The 5-year overall survival (OS) and locoregional recurrence-free survival (LRFS) rates were 76.8% and 89.7%, respectively. Radiotherapy significantly improved the OS (80.9% vs. 62.3%, χ2=15.47, P=0.001) and LRFS (93.4% vs. 77.1%, χ2=19.95, P=0.000). The use of ipsilateral chest wall and supraclavicular nodal radiation was associated with increased 5-year chest wall recurrence free survival (96.8%: 86.2%, χ2=12.66, P= 0.001) and 5-year supraclavicular node recurrence free survival (97.7% :90.7%, χ2=9.98, P=0.002). However, axillary irradiation had no impact on 5-year axillary recurrence free survival (98.4%:96.1%, χ=0.74, P=0.389). In multivariate analysis, absence of radiotherapy (χ2=14.42, P=0.000), 10 or more positive axillary nodes (χ2=21.60, P=0.000), and T4 stage (χ2=10.79, P=0.001) were independent unfavorable prognostic factors for overall survival. Conclusions: Radiotherapy improves the overall survival of breast cancer patients with T3, T4 and/or four or more positive axillary nodes. The chest wall and supraclavicular nodal radiation should be given to this group of patients. (authors)

    The Oncotype DX(®) assay is a validated genomic test that predicts the likelihood of breast cancer recurrence, patient survival within ten years of diagnosis and the benefit of chemotherapy in early-stage, node-negative, estrogen receptor-positive breast cancer. Further markers of recurrence include disseminated tumor cells (DTCs) in the bone marrow (BM) and circulating tumor cells (CTCs) in the blood, particularly stemness-like tumor cells (slCTCs). In this study, Oncotype DX, DTCs, CTCs and slCTCs were used to evaluate the risk of recurrence in 68 patients with human epidermal growth factor receptor 2-negative, early-stage breast cancer. Formalin-fixed, paraffin-embedded tissue sections were analyzed for the expression of 16 cancer genes and 5 reference genes by Oncotype DX, yielding a recurrence score (RS). G2 tumors were evaluated for urokinase-type plasminogen activator (uPA)/plasminogen activator inhibitor type 1 (PAI1) and Ki-67. Two BM aspirates were analyzed by immunocytochemistry for DTCs using the pan-cytokeratin antibody A45-B/B3. CTCs and slCTCs in the blood were detected using the AdnaTest BreastCancer, AdnaTest EMT and the AdnaTest TumorStemCell. Oncotype DX was performed in 68 cases, yielding a low RS in 30/68 patients (44%), an intermediate RS in 29/68 patients (43%) and a high RS in 9/68 patients (13%). DTCs were detected in 19/68 patients (28%), CTCs in 13/68 patients (19%) and slCTCs in 26/68 (38%) patients. Moreover, 8/68 patients (12%) with G2 tumors were positive for uPA, 6/68 (9%) for PAI1 and 21/68 (31%) for Ki-67. Ki-67, progesterone receptor (PR) and G3 tumors were significantly correlated with RS (P<0.001; P=0.006; and P=0,002, respectively), whereas no correlation was identified between DTCs, CTCs, slCTCs and RS. Ki-67 may support therapeutic decisions in cases where Oncotype DX is not feasible. Larger patient cohorts are required to estimate the additional detection of DTCs and CTCs for the determination of risk recurrence.

    Purpose: Use of postmastectomy radiation therapy (PMRT) in breast cancer patients with 1-3 positive nodes is controversial. The objective of this study was to determine whether the size of nodal metastases in this subset could predict who would benefit from PMRT. Methods and Materials: We analyzed 250 breast cancer patients with 1-3 positive nodes after mastectomy treated with contemporary surgery and systemic therapy at our institution. Of these patients, 204 did not receive PMRT and 46 did receive PMRT. Local and regional recurrence risks were stratified by the size of the largest nodal metastasis measured as less than or equal to 5 mm or greater than 5 mm. Results: The median follow-up was 65.6 months. In the whole group, regional recurrences occurred in 2% of patients in whom the largest nodal metastasis measured 5 mm or less vs 6% for those with metastases measuring greater than 5 mm. For non-irradiated patients only, regional recurrence rates were 2% and 9%, respectively. Those with a maximal nodal size greater than 5 mm had a significantly higher cumulative incidence of regional recurrence (P=.013). The 5-year cumulative incidence of a regional recurrence in the non-irradiated group was 2.7% (95% confidence interval [CI], 0.7%-7.2%) for maximal metastasis size of 5 mm or less, 6.9% (95% CI, 1.7%-17.3%) for metastasis size greater than 5 mm, and 16% (95% CI, 3.4%-36.8%) for metastasis size greater than 10 mm. The impact of the maximal nodal size on regional recurrences became insignificant in the multivariable model. Conclusions: In patients with 1-3 positive lymph nodes undergoing mastectomy without radiation, nodal metastasis greater than 5 mm was associated with regional recurrence after mastectomy, but its effect was modified by other factors (such as tumor stage). The size of the largest nodal metastasis may be useful to identify high-risk patients who may benefit from radiation therapy after mastectomy.

    The present study sought to investigate the predictive value of preoperative clinicopathological variables, with a special focus on areca nut chewing, on disease recurrence and progression in patients with non-muscle-invasive bladder cancer (NMIBC). Data from 242 patients diagnosed with NMIBC between 2008 and 2013 were analyzed retrospectively. Fifteen clinicopathological variables were analyzed to evaluate their prognostic value. During a mean observation period of 21 months, disease recurrence occurred in 140 patients (57.9%). On multivariate analysis, heavy-areca nut chewing (HR = 2.18, 95% CI: 1.37–3.47), current smoking (HR = 3.09, 95% CI: 1.99–4.80), moderately impaired estimated glomerular filtration rate (eGFR) (HR = 1.76, 95% CI: 1.09–2.83), severely impaired eGFR (HR = 3.32, 95% CI: 1.70–6.48) and tumor grade (HR = 1.94, 95% CI: 1.36–2.77) were independent factors for recurrence, based on which a risk factor model was developed to stratify patients into high, medium and low risk groups. In conclusion, our study suggests that in addition to quitting smoking, quitting areca nut chewing may also reduce the risk of first recurrence in NMBIC patients, monitoring and preserving their renal function may be beneficial as well. Further prospective studies are needed to verify the prognostic significance of these factors and the risk stratification model in this population. PMID:27385379

    Inflammation may initiate and promote breast cancer development, and be associated with elevated circulating levels of inflammation markers. A total of eight 130 initially healthy women, participated in the population-based Tromsø study (1994-2008). Pre-diagnostic high-sensitivity C-reactive protein (hs-CRP) was assessed. During 14.6 years of follow-up, a total of 192 women developed invasive breast cancer. These cases were followed for additional 7.2 years. Detailed medical records were obtained. We observed an overall positive dose-response relationship between pre-diagnostic hs-CRP and breast cancer risk (hazard ratio (HR) = 1.06, 95 % CI 1.01-1.11). Postmenopausal women with above median levels of hs-CRP (>1.2 mg/l) had a 1.42 (95 % CI 1.01-2.00) higher breast cancer risk compared to postmenopausal women with hs-CRP below median. Postmenopausal women, who were hormone replacement therapy non-users, and were in the middle tertile (0.8-1.9 mg/l), or highest tertile of hs-CRP (>1.9 mg/l), had a 2.31 (95 % CI 1.31-4.03) and 2.08 (95 % CI 1.16-3.76) higher breast cancer risk, respectively, compared with women in the lowest tertile. For each unit increase in pre-diagnostic hs-CRP levels (mg/l), we observed an 18 % increase in disease-free interval (95 % CI 0.70-0.97), and a 22 % reduction in overall mortality (95 % CI 0.62-0.98). Our study supports a positive association between pre-diagnostic hs-CRP and breast cancer risk. In contrast, increased pre-diagnostic hs-CRP was associated with improved overall mortality, but our findings are based on a small sample size, and should be interpreted with caution.

  20. Patterns and Risk Factors of Locoregional Recurrence in T1-T2 Node Negative Breast Cancer Patients Treated With Mastectomy: Implications for Postmastectomy Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: Postmastectomy radiation therapy (PMRT) can reduce locoregional recurrences (LRR) in high-risk patients, but its role in the treatment of lymph node negative (LN-) breast cancer remains unclear. The aim of this study was to identify a subgroup of T1-T2 breast cancer patients with LN- who might benefit from PMRT. Methods and Materials: We retrospectively reviewed 1,136 node-negative T1-T2 breast cancer cases treated with mastectomy without PMRT at the Massachusetts General Hospital between 1980 and 2004. We estimated cumulative incidence rates for LRR overall and in specific subgroups, and used Cox proportional hazards models to identify potential risk factors. Results: Median follow-up was 9 years. The 10-year cumulative incidence of LRR was 5.2% (95% CI: 3.9-6.7%). Chest wall was the most common (73%) site of LRR. Tumor size, margin, patient age, systemic therapy, and lymphovascular invasion (LVI) were significantly associated with LRR on multivariate analysis. These five variables were subsequently used as risk factors for stratified analysis. The 10-year cumulative incidence of LRR for patients with no risk factors was 2.0% (95% CI: 0.5-5.2%), whereas the incidence for patients with three or more risk factors was 19.7% (95% CI: 12.2-28.6%). Conclusion: It has been suggested that patients with T1-T2N0 breast cancer who undergo mastectomy represent a favorable group for which PMRT renders little benefit. However, this study suggests that select patients with multiple risk factors including LVI, tumor size ≥2 cm, close or positive margin, age ≤50, and no systemic therapy are at higher risk of LRR and may benefit from PMRT.

    Full Text Available Context Acute recurrent pancreatitis still poses diagnostic difficulties. The coexistence or moreover the causative relationship of carcinoma of the ampulla of Vater and acute recurrent pancreatitis is fairly rare. Case report We present a case of carcinoma of the ampulla of Vater that presented with acute recurrent necrotizing pancreatitis complicated with pseudocysts. A diagnosis of malignancy in the ampulla was only made after several ERCP attempts due to residual inflammation at the periampullary area. Conclusion Malignancy at the ampulla of Vater causing recurrent episodes of pancreatitis represents a realistic risk and attempts to diagnose the underlying cause should always take into account the possibility of cancer.

    A common single-nucleotide polymorphism in the telomerase reverse transcriptase (TERT) promoter, rs2853669 influences patient survival rates and the risk of developing cancer. Recently, several lines of evidence suggest that the rs2853669 suppresses TERT promoter mutation-mediated TERT expression levels and cancer mortality as well as recurrence rates. However, no reports are available on the impact of rs2853669 on TERT expression in hepatocellular carcinoma (HCC) and its association with patient survival. Here, we found that HCC-related overall and recurrence-free survival rates were not associated with TERT promoter mutation individually, but rs2853669 and the TERT promoter mutation in combination were associated with poor survival rates. TERT mRNA expression and telomere fluorescence levels were greater in patients with HCC who had both the combination. The combination caused TERT promoter methylation through regulating the binding of DNA methyltransferase 1 and histone deacetylase 1 to the TERT promoter in HCC cell lines. The TERT expression level was significantly higher in HCC tumor with a methylated promoter than in that with an unmethylated promoter. In conclusion, we demonstrate a substantial role for the rs2853669 in HCC with TERT promoter mutation, which suggests that the combination of the rs2853669 and the mutation indicate poor prognoses in liver cancer.

  5. Clinical Outcome of Breast Conservation Therapy for Breast Cancer in Hong Kong: Prognostic Impact of Ipsilateral Breast Tumor Recurrence and 2005 St. Gallen Risk Categories

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to evaluate the clinical outcome of breast conservation therapy (BCT) for invasive breast cancers in our predominantly Chinese population. Methods and Materials: Clinical outcomes of 412 T1-2 invasive breast cancers treated by wide local excision and external radiotherapy from 1994 to 2003 were retrospectively analyzed. Only 7% lesions were first detected by mammograms. Adjuvant tamoxifen and chemotherapy were added in 74% and 45% patients, respectively. Results: The median follow-up was 5.4 years. The 5-year actuarial ipsilateral breast tumor recurrence (IBTR) rate, distant failure-free survival, cause-specific survival, and overall survival were 4%, 92%, 96%, and 98%, respectively. The 5-year distant failure-free survival for the low-risk, intermediate-risk, and high-risk categories (2005 St. Gallen) were 98%, 91%, and 80%, respectively (p 0.0003). Cosmetic results were good to excellent in more than 90% of the assessable patients. Grade 3 histology (hazard ratio [HR], 4.461; 95% CI, 1.216-16.360; p = 0.024), age (HR, 0.915; 95% CI, 0.846-0.990; p = 0.027), and close/positive final margins (HR, 3.499; 95% CI, 1.141-10.729; p = 0.028) were significant independent risk factors for IBTR. Both St. Gallen risk categories (p = 0.003) and IBTR (HR, 5.885; 95% CI, 2.494-13.889; p < 0.0005) were independent prognostic factors for distant failure-free survival. Conclusions: Despite the low percentage of mammographically detected lesions, the overall clinical outcome of BCT for invasive breast cancers in the Chinese population is comparable to the Western series. The 2005 St. Gallen risk category is a promising clinical tool, but further validation by large studies is warranted

    Full Text Available The locoregional recurrence (LRR rate was reported as high as approximately 20% in stage I-II breast cancer following mastectomy. To investigate the risk factors for LRR in pT1-2N0-1 breast cancer patients treated with mastectomy but not radiation, and to define a subgroup of patients at high risk of LRR who may benefit from postmastectomy radiotherapy (PMRT.In total, 390 patients with pT1-2N0M0 (n = 307 and pT1-2N1M0 (n = 83 breast cancer who underwent total mastectomy without adjuvant radiotherapy from 2002 to 2011 were enrolled in the study.After a median follow-up period of 5.6 years (range, 0.6-11.3 years, 21 patients had 18 systemic relapses and 12 LRRs including six in the chest wall and eight in the regional nodal area. The 5-year LRR-free survival (LRRFS rates were 97.0% in pN0, 98.8% in pN1, and 97.4% in all patients. Multivariate analysis revealed that age < 50 years (Hazard Ratio, 11.4; p = 0.01 and no adjuvant chemotherapy (Hazard Ratio, 10.2; p = 0.04 were independent risk factors for LRR in pN0 patients. Using these factors, the 5-year LRRFS rates were 100% without any risk factors, 96.4% with one risk factor, and 86.7% with two risk factors. In pN1 patients, multivariate analysis revealed that having a hormone receptor negative tumor (Hazard Ratio, 18.3; p = 0.03 was the only independent risk factor for LRR. The 5-year LRRFS rates were 100.0% for luminal type, and 92.3% for non-luminal type cancer.Patients with pT1-2N0-1 breast cancer who underwent total mastectomy without PMRT could be stratified by nodal stage and risk factors for LRR. PMRT may have of value for node negative patients aged less than 50 years and who are not treated with adjuvant chemotherapy, and for non-luminal type patients with one to three positive nodes.

    Full Text Available In patients, who underwent thyroid surgery or treated with I-131 radioiodine previously for differentiated thyroid cancer, a second surgical intervention carries higher risks due to distortion of the natural anatomy and development of fibrotic/cicatricial tissue. In addition, accurate assessment of current status about extent of the disease is important in terms of success of the surgery. In this case report, we present the positive contribution of intraoperative gamma probe used for lesion detectability and for surgical safety in a patient operated for several times and administered high cumulative dose of radioiodine therapy for diffentiated thyroid carcinoma previously.

    Conclusion: Forequarter amputation can be judiciously used for patients with recurrent or metastatic breast cancer. Patients with recurrent disease without evidence of distant metastases may be considered for curative amputation, while others may receive palliative benefit; disappointingly our patient achieved neither of these outcomes. In the long term, these patients may still have significant psychological problems.

  10. Selecting breast cancer patients with T1-T2 tumors and one to three positive axillary nodes at high postmastectomy locoregional recurrence risk for adjuvant radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To define the individual factors and combinations of factors associated with increased risk of locoregional recurrence (LRR) that may justify postmastectomy radiotherapy (PMRT) in patients with T1-T2 breast cancer and one to three positive nodes. Methods and Materials: The study cohort comprised 821 women referred to the British Columbia Cancer Agency between 1989 and 1997 with pathologic T1-T2 breast cancer and one to three positive nodes treated with mastectomy without adjuvant RT. The 10-year Kaplan-Meier estimates of isolated LRR and LRR with or without simultaneous distant recurrence (LRR ± SDR) were analyzed according to age, histologic findings, tumor location, size, and grade, lymphovascular invasion status, estrogen receptor (ER) status, margin status, number of positive nodes, number of nodes removed, percentage of positive nodes, and systemic therapy use. Multivariate analyses were performed using Cox proportional hazards modeling. A risk classification model was developed using combinations of the statistically significant factors identified on multivariate analysis. Results: The median follow-up was 7.7 years. Systemic therapy was used in 94% of patients. Overall, the 10-year Kaplan-Meier isolated LRR and LRR ± SDR rate was 12.7% and 15.9%, respectively. Without PMRT, a 10-year LRR risk of >20% was identified in women with one to three positive nodes plus at least one of the following factors: age 25% of nodes positive (all p 25% of nodes positive, medial tumor location, and ER-negative status were statistically significant predictors of isolated LRR and LRR ± SDR. In the classification model, the first split was according to age (25% of nodes positive was associated with a risk of LRR ± SDR of 58.0% compared with 23.8% for those with ≤25% of nodes positive (p = 0.01). Of 698 women >45 years, the presence of >25% of nodes positive also conferred a greater LRR ± SDR risk (26.7%) compared with women with ≤25% of nodes positive (10.8%; p

  12. Primary Gleason Grade 4 Impact on Biochemical Recurrence After Permanent Interstitial Brachytherapy in Japanese Patients With Low- or Intermediate-Risk Prostate Cancer

    International Nuclear Information System (INIS)

    Purpose: To reveal a predictive factor for biochemical recurrence (BCR) after permanent prostate brachytherapy (PPB) using iodine-125 seed implantation in patients with localized prostate cancer classified as low or intermediate risk based on National Comprehensive Cancer Network (NCCN) guidelines. Methods and Materials: From January 2004 to December 2009, 414 consecutive Japanese patients with clinically localized prostate cancer classified as low or intermediate risk based on the NCCN guidelines were treated with PPB. The clinical factors including pathological data reviewed by a central pathologist and follow-up data were prospectively collected. Kaplan-Meier and Cox regression analyses were used to assess the factors associated with BCR. Results: Median follow-up was 36.5 months. The 2-, 3-, 4-, and 5-year BCR-free rates using the Phoenix definition were 98.3%, 96.0%, 91.6%, and 87.0%, respectively. On univariate analysis, the Gleason score, especially primary Gleason grade 4 in biopsy specimens, was a strong predicting factor (p < 0.0001), while age, initial prostate-specific antigen (PSA) level, T stage, and minimal dose delivered to 90% of the prostate volume (D90) were insignificant. Multivariate analysis indicated that a primary Gleason grade 4 was the most powerful prognostic factor associated with BCR (hazard ratio = 6.576, 95% confidence interval, 2.597–16.468, p < 0.0001). Conclusions: A primary Gleason grade 4 carried a worse BCR prognosis than the primary grade 3 in patients treated with PPB. Therefore, the indication for PPB in patients with a Gleason sum of 4 + 3 deserves careful and thoughtful consideration.

    2009-06-01

    Full Text Available The notions of local, regional and locoregional recurrences of the mammary gland cancer are singled out in modern literature. A confusion of the recurrence notions leads to difficulties not only in detection of their appearance rate and a clinicomorphological characteristic, but in assessment of the disease treatment and prognosis possibilities. The world data of the recurrence appearance clinicomorphological risk factors such as a primary tumor size, the regional lymph node lesion, the patient age, a presence of multiple centers and peritumoral tumor invasion, a use of postoperative radial therapy and etc. is systematized in the review. The data of the tumor receptor status and genetic factor role in development of the mammary gland local recurrences is presented. A clinicomorphological characteristic of the local recurrences considering a localization, number of tumoral nodes, a tumor shift, a presence of calcinates and such complications as a tumor ulceration or decomposition, a germination of neighboring structures and infection is given. The different types of the local recurrence treatment (surgical, medicinal, radial method and their combinations and a site of local recurrence in prognosis of disease in patients with a mammary gland cancer are studied.

    Purpose: To examine locoregional and distant recurrence (LRR and DR) in women with pT1-2N0 breast cancer according to approximated subtype and clinicopathologic characteristics. Methods and Materials: Two independent datasets were pooled and analyzed. The study participants were 1994 patients with pT1-2N0M0 breast cancer, treated with mastectomy without radiation therapy. The patients were classified into 1 of 5 subtypes: luminal A (ER+ or PR+/HER 2−/grade 1-2, n=1202); luminal B (ER+ or PR+/HER 2−/grade 3, n=294); luminal HER 2 (ER+ or PR+/HER 2+, n=221); HER 2 (ER−/PR−/HER 2+, n=105) and triple-negative breast cancer (TNBC) (ER−/PR−/HER 2−, n=172). Results: The median follow-up time was 4.3 years. The 5-year Kaplan-Meier (KM) LRR were 1.8% in luminal A, 3.1% in luminal B, 1.7% in luminal HER 2, 1.9% in HER 2, and 1.9% in TNBC cohorts (P=.81). The 5-year KM DR was highest among women with TNBC: 1.8% in luminal A, 5.0% in luminal B, 2.4% in luminal HER 2, 1.1% in HER 2, and 9.6% in TNBC cohorts (P<.001). Among 172 women with TNBC, the 5-year KM LRR were 1.3% with clear margins versus 12.5% with close or positive margins (P=.04). On multivariable analysis, factors that conferred higher LRR risk were tumors >2 cm, lobular histology, and close/positive surgical margins. Conclusions: The 5-year risk of LRR in our pT1-2N0 cohort treated with mastectomy was generally low, with no significant differences observed between approximated subtypes. Among the subtypes, TNBC conferred the highest risk of DR and an elevated risk of LRR in the presence of positive or close margins. Our data suggest that although subtype alone cannot be used as the sole criterion to offer postmastectomy radiation therapy, it may reasonably be considered in conjunction with other clinicopathologic factors including tumor size, histology, and margin status. Larger cohorts and longer follow-up times are needed to define which women with node-negative disease have high postmastectomy LRR

    Cancer has been characterized as a heterogeneous disease consisting of many different subtypes. The early diagnosis and prognosis of a cancer type has become a necessity in cancer research. A major challenge in cancer management is the classification of patients into appropriate risk groups for better treatment and follow-up. Such risk assessment is critically important in order to optimize the patient’s health and the use of medical resources, as well as to avoid cancer recurrence. This paper focuses on the application of machine learning methods for predicting the likelihood of a recurrence of cancer. It is not meant to be an extensive review of the literature on the subject of machine learning techniques for cancer recurrence modeling. Other recent papers have performed such a review, and I will rely heavily on the results and outcomes from these papers. The electronic databases that were used for this review include PubMed, Google, and Google Scholar. Query terms used include “cancer recurrence modeling”, “cancer recurrence and machine learning”, “cancer recurrence modeling and machine learning”, and “machine learning for cancer recurrence and prediction”. The most recent and most applicable papers to the topic of this review have been included in the references. It also includes a list of modeling and classification methods to predict cancer recurrence.

  16. Radiation treatment in recurrent squamous cell cancer of the vulva

    International Nuclear Information System (INIS)

    Purpose: To evaluate the treatment and outcome of recurrent vulvar cancer. Methods and Materials: In a retrospective review of 26 women referred to the Department of Radiation Oncology between 1982 and 1995, patient records were analyzed with respect to the findings at original surgery, the time to locoregional recurrence, the location of the recurrence, and the subsequent management and outcome. Results: Sixteen recurrences were managed with a combination of surgery and radiotherapy, and the remainder with radiation treatment, combined with chemotherapy in some cases. The overall survival for the entire cohort at 5 years was 22%. The 5-year survival for those with recurrence confined to the vulva (n = 13) was 46%, compared with 0% for those women with a recurrence located or extending beyond the vulva (p = 0.002). The local control rate was 34.6%. Conclusion: Our results confirm the poor overall prognosis for this condition. In particular, they highlight the importance of the location of the recurrence as a prognostic indicator. Based on this review, we conclude that radiotherapy fields should encompass the region at risk if the intent is curative. Finally, low-dose palliation for groin node recurrence is ineffectual

    To determine the risk factors for local and distant failure in node-negative breast cancer treated with breast-conservative surgery and radiotherapy and to determine the relationship between these two events. We retrospectively selected 908 patients who received conservative surgery and radiotherapy but no chemotherapy between 1980 and 1995, for a mode-negative breast cancer. Patients were divided in two groups according to the status of the margins of resection. All pathology specimens were reviewed. In case of negative margins, the risk factors for local recurrences picked up by the Cox model were histologic multi-focus (P=0.0076), peritumoral vessel invasion (P=0.021) and age {>=}40 years (P=0.024), and in case of involved margins, negative oestrogen receptors (P=0.0012), histologic multi-focus (P=0.0028), and absence of hormonal therapy (P=0.017). The 10-year local recurrence rate was 18 % in case of negative margins and 29 % in case of involved margins, although in the latter case patients received high-dose adjuvant radiotherapy. Accordingly, the 10-year distant failure rates were 16 % and 27 %, respectively. Many arguments suggest that local and distant failures are closely related. Patients with histologic multi-focus or positive margins are at high risk of local failure and then of distant failure, and require a more aggressive initial treatment. (author)

    Purpose: Postmastectomy radiation therapy (PMRT) has been shown to benefit breast cancer patients with 1 to 3 positive lymph nodes, but it is unclear how modern changes in management have affected the benefits of PMRT. Methods and Materials: We retrospectively analyzed the locoregional recurrence (LRR) rates in 1027 patients with T1,2 breast cancer with 1 to 3 positive lymph nodes treated with mastectomy and adjuvant chemotherapy with or without PMRT during an early era (1978-1997) and a later era (2000-2007). These eras were selected because they represented periods before and after the routine use of sentinel lymph node surgery, taxane chemotherapy, and aromatase inhibitors. Results: 19% of 505 patients treated in the early era and 25% of the 522 patients in the later era received PMRT. Patients who received PMRT had significantly higher-risk disease features. PMRT reduced the rate of LRR in the early era cohort, with 5-year rates of 9.5% without PMRT and 3.4% with PMRT (log-rank P=.028) and 15-year rates 14.5% versus 6.1%, respectively; (Cox regression analysis: adjusted hazard ratio [AHR] 0.37, P=.035). However, PMRT did not appear to benefit patients treated in the later cohort, with 5-year LRR rates of 2.8% without PMRT and 4.2% with PMRT (P=.48; Cox analysis: AHR 1.41, P=.48). The most significant factor predictive of LRR for the patients who did not receive PMRT was the era in which the patient was treated (AHR 0.35 for later era, P<.001). Conclusion: The risk of LRR for patients with T1,2 breast cancer with 1 to 3 positive lymph nodes treated with mastectomy and systemic treatment is highly dependent on the era of treatment. Modern treatment advances and the selected use of PMRT for those with high-risk features have allowed for identification of a cohort at very low risk for LRR without PMRT.

    Objective:To measure and compare pre-and post-treatment levels of serum total glutathione-S-transferase (GST) in stage IV cervical cancer patients and erythrocytic glutathione (GSH) and malondialdehyde (MDA) and plasma ceruloplasmin (CP) and total GST in stage IV oral cancer patients and to correlate with the response to treatment during a two year follow-up period in respective cancer groups. Methods:Thirty-four biopsy-proven stage IV oral cancer and cervical cancer patients (n=17 in each group) who underwent same mode of treatment were chosen for this study. Erythrocytic MDA and GSH, CP and serum total GST were measured in all patients before the onset of treatment, and the GST level was only measured in cervical cancer patients after radiotherapy. The levels were compared with their respective prognosis in 2 years. Results:Oral cancer patients with higher pretreatment levels of GSH, CP and GST came with cancer recurrence within 2 years after the onset of treatment. Cervical cancer patients with higher post radiotherapy levels of serum total GST had higher recurrence tate. Conclusions:This study indicates there may be a role for these antioxidant parameters namely GST, GSH, CP in assessment of long term survival and prognosis of cancer patients.

    Full Text Available Background:Febrile Convulsion is the most common convulsive disorder in children,occurring in 2 to 4% of the pediatric population and recurring in 30-50% of cases. Considering the varying recurrence rates reported, thisstudy was conducted at the pediatric ward of the Shaheed BeheshtiGeneral Hospital, between 2000-2001 to determine the frequencyof recurrence and related risk factors in children presenting with theirfirst episode of febrile convulsionMaterials & Methods:A two–year cohort study was performed on 50 children presentingwith the first attack of febrile convulsion. Patient demographic dataincluding age, sex, type and duration of seizure, family history offebrile seizure or epilepsy and the interval between fever onset andoccurrence of seizure were recorded in questionnaires. Those patients,for whom prophylactic medication was not administered, werefollowed at three–month intervals for up to one year. Findings werestatistically analyzed using Fisher’s exact testResults:Recurrence was observed in twelve children (24% out of the fifty,being most common in patients aged less than one year (54.4%.Recurrence rates among children with a positive family history offebrile convulsion, presence of complex febrile seizure and positivefamily history of epilepsy were 42.1%, 42.8% and 25% respectively.From among those children with a “less than one hour” intervalbetween fever onset and occurrence of seizure, recurrence occurredin 43-7% of cases, while in those with a “more than one hourinterval”, 14.7% experienced recurrence.Conclusion:Recurrence rates are increased by certain factors including age-belowone year-, positive family history of febrile convulsion, and a “lessthan one hour” interval between time of fever onset and seizureoccurrence.

  5. Do Standardised Prognostic Algorithms Reflect Local Practice? Application of EORTC Risk Tables for Non-Muscle Invasive (pTa/pT1 Bladder Cancer Recurrence and Progression in a Local Cohort

    Directory of Open Access Journals (Sweden)

    Rajiv Pillai

    2011-01-01

    Full Text Available A risk calculator algorithm to allow prediction of probabilities of 1- and 5-year recurrence and progression rates in individuals with pTa/pT1 bladder cancer has been proposed by the European Organisation for Research and Treatment of Cancer (EORTC and was incorporated into the European Association of Urology guidelines in 2006. We attempted to validate this algorithm in a cohort of patients with known outcome. Prognostic data were collected from a consecutively presenting cohort of 109 patients with non-muscle invasive (pTa/pT1 transitional cell cancer (TCC at a single institution between 1983 and 1985. Using the same statistical models as in the EORTC original paper, predicted probabilities of 1- and 5-year recurrence and progression were calculated. Patients were divided into four risk groups for recurrence (Ir-IVr and progression (Ip-IVp, respectively, using six prognostic criteria. These were then compared to the probabilities predicted in the EORTC algorithm. The predicted 1- and 5-year probabilities of recurrence were significantly higher in the study population as compared to the original EORTC algorithm for all four risk groups. The predicted 1-year probabilities for progression in groups Ip/IIIp and at 5-years for groups Ip/IIp were in accordance with the original algorithm, but were higher for the other progression groups. The concordance for the model of prediction using the study group for recurrence at 1 and 5 years was 62 and 63%, respectively, and for progression was 65 and 67, respectively. We were unable to validate the proposed algorithm in our group of patients. Although our study has limitations that prevent firm conclusions on the validity of the algorithm, it does expose some of the drawbacks of standardised nomograms when applied to local clinical practice.

    Hepatocellular carcinoma (HCC) shows a high rate of recurrence after hepatectomy; predictive factors for early recurrence would help determine optimal therapeutic and management strategies. Among 163 patients with HCC undergoing hepatectomy with curative intent, 46 patients developed recurrence within 1 year. Clinicopathological data were retrospectively analyzed to identify predictive parameters for early recurrence. Survival rates in cases of recurrence within 1 year were worse than those of no recurrence within 1 year or recurrence after 1 year. Protein induced by vitamin K absence/antagonist II (PIVKA-II) greater than 150, positive fucosylated alpha-fetoprotein (L3-AFP), and deviancy from Milan criteria (MC) on preoperative imaging were associated with high risk of early recurrence and total number of these three risk factors predicted the survival. With multivariate analysis, (1) preoperatively, positive factors of two or more among three items of PIVKA-II, L3-AFP, and deviancy from MC; (2) and postoperatively, pathological cancer spread (microscopic vascular invasion and/or intrahepatic metastasis) both represented risks for early recurrence. A combination of three preoperative factors, PIVKA-II, L3-AFP, and MC status, in conjunction with the postoperative factor of cancer spread status represents a significant indicator for recurrence within 1 year. Improving the prognosis of patients with HCC would depend on how to adequately treat those at high risk of early recurrence.

    Evidence from numerous observational and clinical studies suggest that polyphenolic phytochemicals such as phenolic acids in olive oil, flavonols in tea, chocolate and grapes, and isoflavones in soy products reduce the risk of breast cancer. A dietary food pattern naturally rich in polyphenols is the Mediterranean diet and evidence suggests those of Mediterranean descent have a lower breast cancer incidence. Whilst dietary polyphenols have been the subject of breast cancer risk-reduction, this review will focus on the clinical effects of polyphenols on reducing recurrence. Overall, we recommend breast cancer patients consume a diet naturally high in flavonol polyphenols including tea, vegetables (onion, broccoli), and fruit (apples, citrus). At least five servings of vegetables and fruit daily appear protective. Moderate soy protein consumption (5-10 g daily) and the Mediterranean dietary pattern show the most promise for breast cancer patients. In this review, we present an overview of clinical trials on supplementary polyphenols of dietary patterns rich in polyphenols on breast cancer recurrence, mechanistic data, and novel delivery systems currently being researched.

  8. Loco-regional recurrence after mastectomy in high-risk breast cancer-risk and prognosis. An analysis of patients from the DBCG 82 b and c randomization trials

    International Nuclear Information System (INIS)

    Background and purpose: In the DBCG 82 b and c trials, 3083 patients with stages II and III breast cancer were randomised to receive post-mastectomy radiotherapy (RT) versus no RT in addition to systemic therapy. The study showed a decrease in loco-regional recurrences and an improved survival in patients receiving RT. The aim of the present study was to identify risk factors for loco-regional recurrence (LRR), to evaluate the treatment of LRR and to examine the prognosis after LRR. Patients and methods: The 18-year probabilities of LRR were calculated for different prognostic factors using the Kaplan-Meier method. The efficacy of different LRR treatments was compared. The 5-year survival and distant metastases (DM) probability after LRR was calculated with regard to initial randomization group, primary tumor and recurrence related variables. Results: Of the 3083 patients, 535 had a LRR alone as first site of failure. In univariate analyses, large primary tumor size, ductal carcinoma, high malignancy grade, fascia invasion, few removed nodes, many positive nodes and extracapsular invasion were all risk factors for developing LRR. Combined treatment with surgery and RT at the time of LRR increased the persistent loco-regional control. The 5-year probability of subsequent DM was 73% irrespective of initial randomization group. In multivariate analysis, large primary tumor size, many positive nodes, extracapsular invasion, supra/infraclaviculary failures, multiple LRR and a short interval less than 2 years to first LRR were poor prognostic factors for survival. Conclusions: Twenty-seven percent of LRR patients had no DM 5 years after failure. Initial randomization group did not alter the prognosis after LRR. Combined treatment of the LRR with surgery and RT improved persistent loco-regional control compared with surgery or RT alone

    Smooking is associated with several major benign and malignant diseases,representing one of the most important modifiable risk factors.Among urothelial neoplasms,smoking is pivotal in tumor carcinogenesis,but its role in prostate cancer is still controversial.Many authors have failed to demonstrate an association between smoking and prostate cancer.1-3 However,large epidemiological studies have shown that smoking is associated with higher risk of developing and dying of prostate cancer.4 Thus,large sample sizes and long follow-ups are important when studying prostate cancer given that its natural history can be quite long.

    Endometrial adenocarcinoma is the most common gynecologic cancer in the United States. The prognosis is generally favorable, however, a significant number of patients do develop local or distant recurrence. The most common site of recurrence is vaginal. Our aim was to better characterize patients with vaginal recurrence of low-grade endometrioid adenocarcinoma with respect to associated tumor parameters and clinical outcome. We compiled 255 cases of low-grade (FIGO Grade I or II) endometrioid adenocarcinoma on hysterectomy specimens with lymph node dissection. A total of 113 cases with positive lymph nodes or recurrent disease were included in our study group. Seventy-three cases (13 Grade 1, 60 Grade 2) developed extravaginal recurrence and 40 cases (7 Grade 1, 33 Grade 2) developed vaginal recurrence. We evaluated numerous tumor parameters including: percentage myoinvasion, presence of microcystic, elongated, and fragmented pattern of myoinvasion, lymphovascular space invasion, and cervical involvement. Clinical follow-up showed that 30% (34/113) of all patients with recurrent disease died as a result of their disease during our follow-up period, including 31 (42.5%) with extravaginal recurrence and 3 (7.5%) with primary vaginal recurrence (P=0.001). The 3 patients with vaginal recurrence developed subsequent extravaginal recurrence before death. Vaginal recurrence patients show increased cervical involvement by tumor, but lack other risk factors associated with recurrent disease at other sites. There were no deaths among patients with isolated vaginal recurrence, suggesting that vaginal recurrence is not a marker of aggressive tumor biology.

    Ninety-nine patients with recurrent cancers of the head and neck region were treated with surgery, radiation therapy, or combination therapy. The follow-up period ranged from 18 months to 18 years. An initial overall complete response rate of 67% and a partial response rate of 7% (overall response rate-74%) were achieved. The eventual tumor control rate was 15%. Although equal initial response rates were achieved in recurrences at the primary site and the cervical nodes, the eventual local control was better for the former (21% vs. 10%). Patients receiving less than 5,000 rad radiotherapy had a 44% complete response and an 11% eventual tumor control. Patients receiving over 5,000 rad had an 80% complete response and a 25% eventual tumor control.

    2011-01-01

    BRCA1 and BRCA2 mutation carriers with breast cancer have a high risk of ipsilateral breast cancer tumor recurrence (IBTR) and a high lifetime risk of contralateral breast cancer (CBC). The IBTR risk is significantly higher in women who elect breast conservation. Oophorectomy has a protective effect for both ipsilateral breast tumor recurrence and CBC. Patients with younger age of breast cancer onset have a significantly greater risk of CBC. Given the higher risk of IBTR and CBC, when indicat...

  14. DEGRO practical guidelines for radiotherapy of breast cancer VI: therapy of locoregional breast cancer recurrences

    International Nuclear Information System (INIS)

    To update the practical guidelines for radiotherapy of patients with locoregional breast cancer recurrences based on the current German interdisciplinary S3 guidelines 2012. A comprehensive survey of the literature using the search phrases ''locoregional breast cancer recurrence'', ''chest wall recurrence'', ''local recurrence'', ''regional recurrence'', and ''breast cancer'' was performed, using the limits ''clinical trials'', ''randomized trials'', ''meta-analysis'', ''systematic review'', and ''guidelines''. Patients with isolated in-breast or regional breast cancer recurrences should be treated with curative intent. Mastectomy is the standard of care for patients with ipsilateral breast tumor recurrence. In a subset of patients, a second breast conservation followed by partial breast irradiation (PBI) is an appropriate alternative to mastectomy. If a second breast conservation is performed, additional irradiation should be mandatory. The largest reirradiation experience base exists for multicatheter brachytherapy; however, prospective clinical trials are needed to clearly define selection criteria, long-term local control, and toxicity. Following primary mastectomy, patients with resectable locoregional breast cancer recurrences should receive multimodality therapy including systemic therapy, surgery, and radiation +/- hyperthermia. This approach results in high local control rates and long-term survival is achieved in a subset of patients. In radiation-naive patients with unresectable locoregional recurrences, radiation therapy is mandatory. In previously irradiated patients with a high risk of a second local recurrence after surgical resection or in patients with unresectable recurrences, reirradiation should be strongly considered.

  15. Basal Subtype of Invasive Breast Cancer Is Associated With a Higher Risk of True Recurrence After Conventional Breast-Conserving Therapy

    International Nuclear Information System (INIS)

    Purpose: To determine whether breast cancer subtype is associated with patterns of ipsilateral breast tumor recurrence (IBTR), either true recurrence (TR) or elsewhere local recurrence (ELR), among women with pT1–T2 invasive breast cancer (IBC) who receive breast-conserving therapy (BCT). Methods and Materials: From Jan 1998 to Dec 2003, 1,223 women with pT1–T2N0-3 IBC were treated with BCT (lumpectomy plus whole-breast radiation). Ninety percent of patients received adjuvant systemic therapy, but none received trastuzumab. Biologic cancer subtypes were approximated by determining estrogen receptor-positive (ER+), progesterone receptor-positive (PR+), and human epidermal growth factor receptor-2-positive (HER-2+) expression, classified as luminal A (ER+ or PR+ and HER-2 negative [HER-2−]), luminal B (ER+ or PR+ and HER-2+), HER-2 (ER− and PR− and HER-2+), and basal (ER− and PR− and HER-2− ) subtypes. Imaging, pathology, and operative reports were reviewed by two physicians independently, including an attending breast radiologist. Readers were blinded to subtype and outcome. TR was defined as IBTR within the same quadrant and within 3 cm of the primary tumor. All others were defined as ELR. Results: At a median follow-up of 70 months, 24 patients developed IBTR (5-year cumulative incidence of 1.6%), including 15 TR and 9 ELR patients. At 5 years, basal (4.4%) and HER-2 (9%) subtypes had a significantly higher incidence of TR than luminal B (1.2%) and luminal A (0.2%) subtypes (p < 0.0001). On multivariate analysis, basal subtype (hazard ratio [HR], 4.8, p = 0.01), younger age at diagnosis (HR, 0.97; p = 0.05), and increasing tumor size (HR, 2.1; p = 0.04) were independent predictors of TR. Only younger age (HR, 0.95; p = 0.01) significantly predicted for ELR. Conclusions: Basal and HER-2 subtypes are significantly associated with higher rates of TR among women with pT1–T2 IBC after BCT. Younger age predicts for both TR and ELR. Strategies to reduce

    Full Text Available BACKGROUND: In colon cancer patients, obesity, sedentary lifestyle, and high dietary glycemic load have been associated with increased risk of cancer recurrence. High sugar-sweetened beverage intake has been associated with obesity, diabetes, and cardio-metabolic diseases, but the influence on colon cancer survival is unknown. METHODS: We assessed the association between sugar-sweetened beverage consumption on cancer recurrence and mortality in 1,011 stage III colon cancer patients who completed food frequency questionnaires as part of a U.S. National Cancer Institute-sponsored adjuvant chemotherapy trial. Hazard ratios (HRs and 95% confidence intervals (CIs were calculated with Cox proportional hazard models. RESULTS: Patients consuming ≥ 2 servings of sugar-sweetened beverages per day experienced an adjusted HR for disease recurrence or mortality of 1.67 (95% CI, 1.04-2.68, compared with those consuming <2 servings per month (P(trend = 0.02. The association of sugar-sweetened beverages on cancer recurrence or mortality appeared greater among patients who were both overweight (body mass index ≥ 2 5 kg/m(2 and less physically active (metabolic equivalent task-hours per week <18 (HR = 2.22; 95% CI, 1.29-3.81, P(trend = 0.0025.

  4. HER2 overexpression a major risk factor for recurrence in pT1a-bN0M0 breast cancer: results from a French regional cohort

    International Nuclear Information System (INIS)

    The management of pT1a-bN0M0 breast cancer remains an area of controversy. Data from 714 patients classified as having pT1a-bN0M0 breast cancer and treated, from 1999 to 2004 in the Languedoc-Roussillon France, were analyzed. The human epidermal growth factor receptor 2 (HER2) status analyses were centralized. The objective of this study was to describe the prognosis of pT1a-bN0M0 breast cancer according to HER2 distribution and hormonal status. The median follow-up was 6.4 years. Ten-year overall survival was 94%. HER2 overexpression was observed in 6.1% of the patients. The 10-year prognosis of patients with HER2-positive tumors was worse than that of those with HER2-negative (disease-free survival 73% vs. 89%, P < 0.0001). Tumor size (T1a/T1b) was not a relevant prognostic factor. The co-expression of HER2 with hormonal receptors (HR) was associated with high recurrence at 10 years. In both univariate and multivariate analyses, the most relevant prognostic factor for this population was HER2 amplification. In multivariate analysis, patients with HER2-positive tumors had higher risk of mortality (HR, 3.89; 95% CI, 1.58–9.56). In pT1a-bN0M0 breast cancers, HER2 amplification or overexpression is a risk factor for recurrence. In HER2-positive breast cancers, HR expression is associated with a poor prognosis despite the hormone therapy. For this population, a personalized management may be required

    2010-03-01

    Full Text Available Abstract Background Over-expression of HER2 in a subset of breast cancers (HER2+ is associated with high histological grade and aggressive clinical course. Despite these distinctive features, the differences in response of HER2+ patients to both adjuvant cytotoxic chemotherapy and targeted therapy (e.g. trastuzumab suggests that unrecognized biologic and clinical diversity is confounding treatment strategies. Furthermore, the small but established risk of cardiac morbidity with trastuzumab therapy compels efforts towards the identification of biomarkers that might help stratify patients. Methods A single institution tissue array cohort assembled at the Clearview Cancer Institute of Huntsville (CCIH was screened by immunohistochemistry staining using a large number of novel and commercially available antibodies to identify those with a univariate association with clinical outcome in HER2+ patients. Staining with antibody directed at TRMT2A was found to be strongly associated with outcome in HER2+ patients. This association with outcome was tested in two independent validation cohorts; an existing staining dataset derived from tissue assembled at the Cleveland Clinic Foundation (CCF, and in a new retrospective study performed by staining archived paraffin blocks available at the Roswell Park Cancer Institute (RPCI. Results TRMT2A staining showed a strong correlation with likelihood of recurrence at five years in 67 HER2+ patients from the CCIH discovery cohort (HR 7.0; 95% CI 2.4 to 20.1, p HER2+ patients from the CCF cohort (HR 3.6; 95% CI 1.3 to 10.2, p Conclusions Studies from three independent single institution cohorts support TRMT2A protein expression as a biomarker of increased risk of recurrence in HER2+ breast cancer patients. These results suggest that TRMT2A expression should be further studied in the clinical trial setting to explore its predictive power for response to adjuvant cytotoxic chemotherapy in combination with HER2 targeted

  9. Using the lymph nodal ratio to predict the risk of locoregional recurrence in lymph node-positive breast cancer patients treated with mastectomy without radiation therapy

    International Nuclear Information System (INIS)

    To evaluate the prognostic value of axillary lymph node ratio (LNR) as compared to the number of involved nodes (pN stage) in patients with axillary lymph node-positive breast cancer treated with mastectomy without radiation. We performed a retrospective analysis of the clinical data of patients with stage II-III node-positive breast cancer (N=1068) between 1998 and 2007. Locoregional recurrence-free survival (LRFS) and overall survival (OS) were compared based on the LNR and pN staging. A total of 780 cases were classified as pN1, 183 as pN2, and 105 as pN3. With respect to LNR, 690 cases had a LNR from 0.01-0.20, 269 cases a LNR from 0.21-0.65, and 109 cases a LNR > 0.65. The median follow-up time was 62 months. Univariate analysis showed that both LNR and pN stage were prognostic factors of LRFS and OS (p<0.05). Multivariate analysis indicated that LNR was an independent prognostic factor of LRFS and OS (p<0.05). pN stage had no significant effect on LRFS or OS (p>0.05). In subgroup analysis, the LNR identified groups of patients with different survival rates based on pN stage. LNR is superior to pN staging as a prognostic factor in lymph node-positive breast cancer after mastectomy, and should be used as one of the indications for adjuvant radiation therapy

    The recurrence of cerebral palsy in the same family is uncommon. We, however, report on two families with two or more affected siblings. In both families, numerous potential risk factors were identified including environmental, obstetric, and possible maternal effects. We hypothesize that multiple risk factors may lead to the increased risk of recurrence of cerebral palsy in families. Intrinsic and maternal risk factors should be investigated in all cases of cerebral palsy to properly counsel...

    2016-03-15

    In a previous study, the transmembrane protein FXYD-3 was suggested as a biomarker for a lower survival rate and reduced radiosensitivity in rectal cancer patients receiving preoperative radiotherapy. The purpose of preoperative irradiation in rectal cancer is to reduce local recurrence. The aim of this study was to investigate the potential role of FXYD-3 as a biomarker for increased risk for local recurrence of rectal cancer. FXYD-3 expression was immunohistochemically examined in surgical specimens from a cohort of patients with rectal cancer who developed local recurrence (n = 48). The cohort was compared to a matched control group without recurrence (n = 81). Weak FXYD-3 expression was found in 106/129 (82%) of the rectal tumors and strong expression in 23/129 (18%). There was no difference in the expression of FXYD-3 between the patients with local recurrence and the control group. Furthermore there was no difference in FXYD-3 expression and time to diagnosis of local recurrence between patients who received preoperative radiotherapy and those without. Previous findings indicated that FXYD-3 expression may be used as a marker of decreased sensitivity to radiotherapy or even overall survival. We were unable to confirm this in a cohort of rectal cancer patients who developed local recurrence.

    Full Text Available Surgical removal of solid tumors is of utmost importance as total resection can be curative. The surgical insult however itself may result in tumor micrometastasis coupled with depression of cell-mediated immunity culminating in tumor recurrence. Recent research suggests that few anesthetic agents or procedures can influence pathophysiology of metastasis in the postoperative period. Whereas opioids and volatile anesthetics have been implicated in angiogenesis and immunosuppression, evidences accumulated over the recent years have undoubtedly highlighted the attenuation of immunosuppression by regional anesthetic agents thereby making it superior over general anesthesia in preventing cancer recurrence. As anesthetic drugs are given at that time when patient is at the maximum risk of spread of metastasis, thus an understanding of the effect of anesthesia drugs and their impact on tumor metastasis is important so that appropriate anesthetic strategy can be made to improve long term survival in these patients. The purpose of the present review is therefore to emphasize the pivotal role of various anesthetic agents and anesthesia techniques in preventing tumor recurrence after surgery.

  16. Risk and timing of biochemical recurrence in pT3aN0/Nx prostate cancer with positive surgical margin – A multicenter study

    International Nuclear Information System (INIS)

    Background and purpose: Positive surgical margins (PSM) after radical prostatectomy have been shown to be associated with impaired outcome. In pT3pN0 patients with PSM either immediate radiotherapy or clinical and biological monitoring followed by salvage radiotherapy is recommended by the latest guidelines of the European Association of Urology. Materials and methods: A retrospective, multicenter study of eight urological centers was conducted on 536 prostatectomy patients with pT3aN0/NxR1 tumors and no neoadjuvant/adjuvant therapy. A pathological re-review of all prostate specimens was performed. Association of clinical and pathological features with biochemical recurrence (BCR) was analyzed using univariate and multivariate analysis. Results: With 48 months median follow-up, BCR occurred in 39.7%. Preoperative PSA value, performance of pelvic lymph node dissection and Gleason score were significantly associated with BCR. In multivariate analysis, Gleason score was the only independent prognostic factor (p < 0.001) for BCR. Five-year BCR-free survival rates were 74%, 70%, 38%, and 51% with Gleason score 6, 3 + 4 = 7a, 4 + 3 = 7b, and 8–10, respectively. Conclusions: In pT3aN0/NxR1 patients with no adjuvant/neoadjuvant treatment, Gleason Score permits independent prediction of the risk for BCR. These findings could help to estimate and discuss the individual risk for BCR with our patients on an individual basis

    AIM: To investigate biological prevention with flavonoids the recurrence risk of neoplasia was studied in patients with resected colorectal cancer and after adenoma polypectomy.METHODS: Eighty-seven patients, 36 patients with resected colon cancer and 51 patients after polypectomy,were divided into 2 groups: one group was treated with a flavonoid mixture (daily standard dose 20 mg apigenin and 20 mg epigallocathechin-gallat, n = 31)and compared with a matched control group (n = 56).Both groups were observed for 3-4 years by surveillance colonoscopy and by questionnaire.RESULTS: Of 87 patients enrolled in this study, 36 had resected colon cancer and 29 of these patients had surveillance colonoscopy. Among the flavonoid-treated patients with resected colon cancer (n = 14), there was no cancer recurrence and one adenoma developed. In contrast the cancer recurrence rate of the 15 matched untreated controls was 20% (3 of 15) and adenomas evolved in 4 of those patients (27%). The combined recurrence rate for neoplasia was 7% (1 of 14) in the treated patients and 47% (7 of 15) in the controls (p = 0.027).CONCLUSION: Sustained long-term treatment with a flavonoid mixture could reduce the recurrence rate of colon neoplasia in patients with resected colon cancer.

    2012-01-01

    Full Text Available Abstract Background Distant recurrence is one of the most important risk factors in overall survival, and distant recurrence is related to a complex biologic interaction of seed and soil factors. The aim of the study was to investigate the association between the molecular subtypes and patterns of distant recurrence in patients with breast cancer. Methods In an investigation of 313 women with breast cancer who underwent surgery from 1994 and 2000, the expressions of estrogen and progestrone receptor (ER/PR, and human epithelial receptor-2 (HER2 were evaluated. The subtypes were defined as luminal-A, luminal-HER2, HER2-enriched, and triple negative breast cancer (TNBC according to ER, PR, and HER2 status. Results Bone was the most common site of distant recurrence. The incidence of first distant recurrence site was significantly different among the subtypes. Brain metastasis was more frequent in the luminal-HER2 and TNBC subtypes. In subgroup analysis, overall survival in patients with distant recurrence after 24 months after surgery was significantly different among the subtypes. Conclusions Organ-specific metastasis may depend on the molecular subtype of breast cancer. Tailored strategies against distant metastasis concerning the molecular subtypes in breast cancer may be considered.

  5. Weight Gain, Metabolic Syndrome, and Breast Cancer Recurrence: Are Dietary Recommendations Supported by the Data?

    Directory of Open Access Journals (Sweden)

    Colin E. Champ

    2012-01-01

    Full Text Available Metabolic syndrome, which can include weight gain and central obesity, elevated serum insulin and glucose, and insulin resistance, has been strongly associated with breast cancer recurrence and worse outcomes after treatment. Epidemiologic and prospective data do not show conclusive evidence as to which dietary factors may be responsible for these results. Current strategies employ low-fat diets which emphasize supplementing calories with increased intake of fruit, grain, and vegetable carbohydrate sources. Although results thus far have been inconclusive, recent randomized trials employing markedly different dietary strategies in noncancer patients may hold the key to reducing multiple risk factors in metabolic syndrome simultaneously which may prove to increase the long-term outcome of breast cancer patients and decrease recurrences. Since weight gain after breast cancer treatment confers a poor prognosis and may increase recurrence rates, large-scale randomized trials are needed to evaluate appropriate dietary interventions for our breast cancer patients.

    Beloeil, H; Nouette-Gaulain, K

    2012-06-01

    Surgical treatment of cancer is usually necessary but it can paradoxically aggravate the patient outcome by increasing the risk of recurrence. Many perioperative factors have been shown to contribute to the dissemination of the tumor: surgery itself, stress, inflammation, pain, anaesthetic drugs, blood transfusion, etc. The type of anaesthesia chosen in the cancer patient could then be crucial and influence the evolution of the disease. Experimental, preclinical and retrospective studies have suggested that a regional anesthesia associated or not with a general anesthesia for carcinologic surgery might reduce the risk of cancer recurrence. This text reviews the factors promoting the recurrence of tumors after carcinologic surgery and the potential possibilities of protection associated with the type of anaesthesia chosen.

    2014-01-01

    Background E75 (nelipepimut-S) is a human leukocyte antigen (HLA)-A2/A3-restricted immunogenic peptide derived from the HER2 protein. We have conducted phase I/II clinical trials vaccinating breast cancer patients with nelipepimut-S and granulocyte–macrophage colony-stimulating factor (GM-CSF) in the adjuvant setting to prevent disease recurrence. All patients have completed 60 months follow-up, and here, we report the final analyses. Patients and methods The studies were conducted as dose escalation/schedule optimization trials enrolling node-positive and high-risk node-negative patients with tumors expressing any degree of HER2 (immunohistochemistry 1–3+). HLA-A2/3+ patients were vaccinated; others were followed prospectively as controls. Local and systemic toxicity was monitored. Clinical recurrences were documented, and disease-free survival (DFS) was analyzed by Kaplan–Meier curves; groups were compared using log-rank tests. Results Of 195 enrolled patients, 187 were assessable: 108 (57.8%) in the vaccinated group (VG) and 79 (42.2%) in the control group (CG). The groups were well matched for clinicopathologic characteristics. Toxicities were minimal. Five-year DFS was 89.7% in the VG versus 80.2% in the CG (P = 0.08). Due to trial design, 65% of patients received less than the optimal vaccine dose. Five-year DFS was 94.6% in optimally dosed patients (P = 0.05 versus the CG) and 87.1% in suboptimally dosed patients. A voluntary booster program was initiated, and among the 21 patients that were optimally boosted, there was only one recurrence (DFS = 95.2%). Conclusion The E75 vaccine is safe and appears to have clinical efficacy. A phase III trial evaluating the optimal dose and including booster inoculations has been initiated. Clinical Trials NCT00841399, NCT00584789. PMID:24907636

    The surgical outcome of most early gastric cancer (EGC)is usually satisfactory. Some cases show bone metastasis even though the depth of cancer invasion is confined to the mucosa. The most frequent site for recurrence of EGC is the liver. Cases of EGC with bone metastasis are reviewed to clarify the clinicopathological characteristics of EGC giving rise to bone metastasis. Possible mechanisms and risk factors underlying this rare condition are proposed.Forty-six cases of bone metastasis from EGC are reviewed from published reports and meeting proceedings in Japan.This investigation suggests that risk factors for bone metastasis from EGC include depressed-type signet-ring cell carcinoma, poorly differentiated carcinoma, and/or the likely involvement of lymph node metastasis, even though the cancer is confined to the gastric mucosa. The risk factors do not include recurrence of EGC in the liver. We speculate that the mechanism of bone metastasis from EGC is via lymphatic channels and systemic circulation. Postoperative follow-up of cases should consider the development of bone metastasis from EGC. We propose the use of elevated alkaline phosphatase levels for the detection of bone metastasis and recommend bone scintigraphy in positive cases.

    2016-01-01

    An 84-year-old woman developed a cerebellar syndrome having undergone a total abdominal hysterectomy and bilateral salpingo-oophorectomy for endometrial cancer 1 year previously. She was found to be anti-Yo antibody positive and was diagnosed with paraneoplastic cerebellar degeneration (PCD). A subsequent positron emission tomography scan and lymph node biopsy identified recurrence of her endometrial cancer. This case illustrates how PCD can be an indicator of cancer recurrence, underlines the significance of PCD as a prompt to search for underlying malignancy, and highlights the difficulties PCD poses to the clinician in terms of diagnosis and management.

    Recurrent mutations constituted nearly three quarters of all BRCA1 mutations and almost half of all BRCA2 mutations identified in the first cohort of the Nigerian Breast Cancer Study. To further characterize breast/ovarian cancer risks associated with BRCA1/BRCA2 mutations in the African diaspora, we genotyped recurrent mutations among Nigerian, African American, and Barbadian breast cancer patients. A replication cohort of 356 Nigerian breast cancer patients was genotyped for 12 recurrent BRCA1/2 mutant alleles (Y101X, 1742insG, 4241delTG, M1775R, 4359insC, C64Y, 1623delTTAAA, Q1090X, and 943ins10 from BRCA1, and 1538delAAGA, 2630del11, and 9045delGAAA from BRCA2) by means of SNaPshot followed by direct sequencing or by direct sequencing alone. In addition, 260 African Americans and 118 Barbadians were genotyped for six of the recurrent BRCA1 mutations by SNaPshot assay. Of all the BRCA1/2 recurrent mutations we identified in the first cohort, six were identified in 11 patients in the replication study. These mutation carriers constitute 3.1 % [95 % Confidence Interval (CI) 1.6-5.5 %] of the replication cohort. By comparison, 6.9 % (95 % CI 4.7-9.7 %) of the discovery cohort carried BRCA1/2 recurrent mutations. For the subset of recurrent mutations we tested in breast cancer cases from Barbados or the United States, only two 943ins10 carriers were identified in African Americans. Nigerian breast cancer patients from Ibadan carry a broad and unique spectrum of BRCA1/2 mutations. Our data suggest that BRCA1/2 mutation testing limited to recurrent mutations is not sufficient to understand the BRCA1/2-associated breast cancer risk in African populations in the diaspora. As the cost of Sanger sequencing is considerably reduced, deploying innovative technologies such as high throughput DNA sequencing of BRCA1/2 and other cancer susceptibility genes will be essential for identifying high-risk individuals and families to reduce the burden of aggressive early onset breast

    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.

  19. Impact of Screening and Risk Factors for Local Recurrence and Survival After Conservative Surgery and Radiotherapy for Early Breast Cancer: Results From a Large Series With Long-Term Follow-Up

    International Nuclear Information System (INIS)

    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.

    Previous studies suggest that disease recurrence peaks at around 2 years in patients with early stage breast cancer (EBC), but provide no data regarding recurrence type. This retrospective analysis aimed to identify early recurrence types and risk factors in estrogen receptor-positive (ER+) EBC patients treated with adjuvant tamoxifen following breast cancer surgery. Postmenopausal women diagnosed with ER+ EBC from 1995 to 2004 were evaluated. Annual hazard ratios (HR) for recurrence at different sites were calculated. Time-dependent Cox regression analysis was used to identify predictors of recurrence within 2.5 years of diagnosis, including factors that were more strongly predictive of early than later recurrence. Of 3,614 patients evaluated, 476 developed recurrence during the 5-year median follow-up. Cumulative recurrence rates at 2.5 years (95% confidence interval) were: overall 6.3% (5.5-7.1), locoregional 1.1% (0.7-1.5), contralateral 0.5% (0.3-0.7), and distant 4.8% (4.0-5.6). The annual HR of overall recurrence peaked at 2 years (4.3% per annum). The majority of this peak represented distant recurrence (3.4% per annum). In Cox regression analysis, tumor size and grade, lymph node involvement, lymphovascular invasion, and symptomatic presentation were significant independent predictors of early recurrence. Age at diagnosis was independently predictive of recurrence within 2.5 years of diagnosis but not later recurrence. This study identified an early recurrence peak at 2 years, most of which were distant recurrences. Implementing an aromatase inhibitor after an initial 2-3 years of tamoxifen fails to address this early peak of distant recurrence and the potential breast cancer-associated mortality. PMID:19112615

    Crohn's disease (CD) is a chronic inflammatory disease of the digestive tract with systemic manifestations. Etiology is unknown, even if immunological, genetic and environmental factors are involved. The majority of CD patients require surgery during their lifetime due to progressive bowel damage, but, even when all macroscopic lesions have been removed by surgery, the disease recurs in most cases. Postoperative management represents therefore a crucial mean for preventing recurrence. Several drugs and approaches have been proposed to achieve this aim. Endoscopic inspection of the ileocolic anastomosis within 1 year from surgery is widely encouraged, given that endoscopic recurrence is one of the greatest predictors for clinical recurrence. A strategy should be planned only after stratifying patients according to their individual risk of recurrence, avoiding unnecessary therapies when possible benefits are reduced, and selecting high-risk patients for more aggressive intervention.

    International Nuclear Information System (INIS)

    Objective: To investigate the causes of groin recurrence in patients with vulval cancer Early vulvar cancer; who previously had negative nodes following superficial inguinal node dissection (SIND). Groin recurrence Material and methods: Forty-one patients with squamous cell carcinoma of the vulva (stage I or II) were operated upon. The primary treatment was wide local excision with 2 cm safety margin and superficial inguinal lymphadenectomy. Six patients had ipsilateral and one patient had bilateral groin recurrence. Those patients were subjected to deep inguinal node dissection (one patient required bilateral node dissection). Results: The mean age at time of diagnosis was 59 years (range 51-68). The median follow-up period for all patients was 63 months (range 24-71) and that of the recurrent cases was 20 months (range 12-38). The mean depth of invasion of the recurrent cases was 5.5 mm (range 5-5.9 mm) and the mean diameter of the primary tumor in recurrent cases was 3.8 cm (range 3-4.5 cm). All recurrent cases had a high grade of the primary tumor. The median interval to recurrence was 21 months (range 12-57). The groin recurrence rate after negative SIND was 17% (7/41 patient- s).The mean number of nodes resected per groin was eight (range 1 17). The nodes ranged in size from 0.2 to 4.0 cm. Conclusion: Carcinoma of the vulva with the following criteria (size of tumor is greater than 3 cm, depth of invasion greater than 5 mm, and high grade tumors) is at high risk of recurrence

    Full Text Available BACKGROUND: In this manuscript, we assessed tumor recurrence and tumor-related mortality in a clinical series of endometrial cancer patients. MATERIALS AND METHODS: A retrospective evaluation of 276 patients (mean age 64 years with histologically confirmed endometrial cancer treated at a single hospital in Madrid (Spain was conducted. The median follow-up was estimated using the inverse Kaplan–Meier method. RESULTS: Salient findings were endometrioid carcinoma (84.8% of cases, grade G1 (48.9% and stages IB (35.1% and IC (23.2%. Myometrial infiltration >50% was documented in 31.2% of cases and lymphovascular space invasion in 11.9%. After surgery, 52.5% of patients were classified into the low risk group, 21.4% into the intermediate risk group and 26.1% into the high risk group. Tumor recurrence occurred in 14.5% of patients, with an estimated median follow-up of 45 months (95% confidence interval (CI: 41.2–48.8, locoregional recurrence in 42.5% and distant recurrences in 57.5%. Furthermore, 40% of tumor recurrences developed during the first year after primary treatment and 90% over the first 3 years of follow-up. The tumor-related mortality rate was 15.9%. The estimated median follow-up was 46 months (95% CI: 43.0–49.0. Furthermore, 5.07% of death because of tumor developed during the first year after primary treatment and 13.77% over the first 3 years of follow-up. CONCLUSION: The rates of tumor-related death and tumor recurrence in endometrial cancer patients are low, with the highest percentages occurring within 3 years of primary treatment. Most of the recurrences occur outside the pelvis.

    The treatment of locoregionally recurrent breast cancer in patients who have previously undergone radiation therapy is challenging. Special techniques are often required that both eradicate the disease and minimize the risks of retreatment. We report the case of a patient with an early-stage left breast cancer who developed inflammatory-type recurrence requiring re-irradiation of the chest wall using bolus electron conformal therapy with image-guided treatment delivery. The patient was a 51-year-old woman who had undergone lumpectomy, axillary lymph node dissection, and adjuvant whole-breast radiation therapy for a stage I left breast cancer in June 1998. In March 2009, she presented at our institution with biopsy-proven recurrent inflammatory carcinoma and was aggressively treated with multi-agent chemotherapy followed by mastectomy that left a positive surgical margin. Given the patient's prior irradiation and irregular chest wall anatomy, bolus electron conformal therapy was used to treat her chest wall and draining lymphatics while sparing the underlying soft tissue. The patient still had no evidence of disease 21 months after treatment. Our results indicate that bolus electron conformal therapy is an accessible, effective radiation treatment approach for recurrent breast cancer in patients with irregular chest wall anatomy as a result of surgery. This approach may complement standard techniques used to reduce locoregional recurrence in the postmastectomy setting.

  9. Imaging of prostate cancer local recurrences: why and how?

    International Nuclear Information System (INIS)

    Because prostate cancer local recurrences can be efficiently treated by salvage therapies, it becomes critical to detect them early. The first alert is the rise of the prostate specific antigen (PSA) level after the post-treatment nadir, which can correspond to a distant recurrence, a local recurrence or both. This so-called biochemical failure (BF) is defined as PSA level >0.2 ng/ml after radical prostatectomy (RP) and PSA level > nadir+2 ng/ml after radiotherapy. There is no consensual definition of BF after cryotherapy, high-intensity focused ultrasound (HIFU) ablation or brachytherapy. Local recurrences after RP are treated by radiotherapy, those after radiotherapy by RP, cryotherapy, brachytherapy or HIFU ablation. Recurrences after cryotherapy or HIFU ablation can be treated by a second session or radiotherapy. Recurrences after brachytherapy are difficult to treat. In patients with BF, MRI can detect local recurrences, whatever the initial treatment was. Dynamic contrast-enhanced MRI seems particularly accurate. The role of spectroscopy remains controversial. Ultrasound-based techniques are less accurate, but this may change with the advent of ultrasonic contrast media. These recent advances in imaging may improve the outcome of salvage therapies (by improving patient selection and treatment targeting) and should open the way to focal salvage treatments in the near future.

  16. Contralateral breast cancer risk

    International Nuclear Information System (INIS)

    The use of breast-conserving treatment approaches for breast cancer has now become a standard option for early stage disease. Numerous randomized studies have shown medical equivalence when mastectomy is compared to lumpectomy followed by radiotherapy for the local management of this common problem. With an increased emphasis on patient involvement in the therapeutic decision making process, it is important to identify and quantify any unforeseen risks of the conservation approach. One concern that has been raised is the question of radiation- related contralateral breast cancer after breast radiotherapy. Although most studies do not show statistically significant evidence that patients treated with breast radiotherapy are at increased risk of developing contralateral breast cancer when compared to control groups treated with mastectomy alone, there are clear data showing the amount of scattered radiation absorbed by the contralateral breast during a routine course of breast radiotherapy is considerable (several Gy) and is therefore within the range where one might be concerned about radiogenic contralateral tumors. While radiation related risks of contralateral breast cancer appear to be small enough to be statistically insignificant for the majority of patients, there may exist a smaller subset which, for genetic or environmental reasons, is at special risk for scatter related second tumors. If such a group could be predicted, it would seem appropriate to offer either special counselling or special prevention procedures aimed at mitigating this second tumor risk. The use of genetic testing, detailed analysis of breast cancer family history, and the identification of patients who acquired their first breast cancer at a very early age may all be candidate screening procedures useful in identifying such at- risk groups. Since some risk mitigation strategies are convenient and easy to utilize, it makes sense to follow the classic 'ALARA' (as low as reasonably

  20. Risk factors for locoregional recurrence in patients with resected N1 non-small cell lung cancer: a retrospective study to identify patterns of failure and implications for adjuvant radiotherapy

    International Nuclear Information System (INIS)

    Meta-analysis of randomized trials has shown that postoperative radiotherapy (PORT) had a detrimental effect on overall survival (OS) in patients with resected N1 non–small cell lung cancer (NSCLC). Conversely, the locoregional recurrence (LR) rate is reported to be high without adjuvant PORT in these patients. We have evaluated the pattern of failure, actuarial risk and risk factors for LR in order to identify the subset of N1 NSCLC patients with the highest risk of LR. These patients could potentially benefit from PORT. We conducted a retrospective study on 199 patients with pathologically confirmed T1–3N1M0 NSCLC who underwent surgery. None of the patients had positive surgical margins or received preoperative therapy or PORT. The median follow-up was 53.8 months. Complete mediastinal lymph node (MLN) dissection and examination was defined as ≥3 dissected and examined MLN stations; incomplete MLN dissection or examination (IMD) was defined as <3 dissected or examined MLN stations. The primary end point of this study was freedom from LR (FFLR). Differences between patient groups were compared and risk factors for LR were identified by univariate and multivariate analyses. LR was identified in 41 (20.6%) patients, distant metastasis (DM) was identified in 79 (39.7%) patients and concurrent LR and DM was identified in 25 (12.6%) patients. The 3- and 5-year OS rates in patients with resected N1 NSCLC were 78.4% and 65.6%, respectively. The corresponding FFLR rates were 80.8% and 77.3%, respectively. Univariate analyses identified that nonsmokers, ≤23 dissected lymph nodes, visceral pleural invasion and lymph node ratio >10% were significantly associated with lower FFLR rates (P < 0.05). Multivariate analyses further confirmed positive lymph nodes at station 10 and IMD as risk factors for LR (P < 0.05). The 5-year LR rate was highest in patients with both these risk factors (48%). The incidence of LR in patients with surgically resected T1–3N1M0 NSCLC is

METHOD AND RESULTS: We report the case of a postmenopausal female patient who, five years after anterior resection, developed a primary ovarian malignancy that invaded a rectal anastomosis and in so doing mimicked a recurrence of a Dukes A rectal cancer. To our knowledge, such an occurrence has not been described previously in the literature. CONCLUSION: This case illustrates the possible benefits of routine prophylactic oophorectomy at the time of colorectal cancer resection.

    The clinical features of prostate cancer do not provide an accurate determination of patients undergoing biochemical relapse and are therefore not suitable as indicators of prognosis for recurrence. New molecular markers are needed for proper pre-treatment risk stratification of patients. Our aim was to assess the value of altered expression of syndecan-1 and -2 as a marker for predicting biochemical relapse in patients with clinically localized prostate cancer treated by radical prostatectomy. The expression of syndecan-1 and -2 was examined by immunohistochemical staining in a series of 60 paraffin-embedded tissue samples from patients with localized prostate cancer. Ten specimens from patients with benign prostatic hyperplasia were used as non-malignant controls. Semiquantitative analysis was performed to evaluate the staining patterns. To investigate the prognostic value, Kaplan-Meier survival curves were performed and compared by a log-rank test. In benign samples, syndecan-1 was expressed in basal and secretory epithelial cells with basolateral membrane localisation, whereas syndecan-2 was expressed preferentially in basal cells. In prostate cancer samples, the expression patterns of both syndecans shifted to granular-cytoplasmic localisation. Survival analysis showed a significant difference (P<0.05) between normal and altered expression of syndecan-1 and -2 in free prostate-specific antigen recurrence survival curves. These data suggest that the expression of syndecan-1 and -2 can be used as a prognostic marker for patients with clinically localized prostate cancer, improving the prostate-specific antigen recurrence risk stratification.

    Purpose: To investigate prognostic and risk factors for recurrence after stereotactic body radiation therapy (SBRT) in patients with stage I non-small cell lung carcinoma (NSCLC), focusing on dual time point [18]F-fluorodeoxyglucose positron emission tomography (FDG PET). Materials and methods: We prospectively evaluated 57 patients with stage I NSCLC (45 T1N0M0 and 12 T2N0M0) who had undergone pretreatment FDG-PET/CT and were subsequently treated with SBRT. All patients received a whole-body PET/CT scan at 60 min and a whole-lung at 120 min after the injection. The maximum standardized uptake value (SUV) and retention index (RI) of the lesions were calculated. Local recurrence, regional lymph node metastasis, distant metastasis, and the recurrence pattern were evaluated. Cox proportional hazard regression analyses were performed to evaluate prognostic factors or risk factors of recurrence. Results: During the median follow-up period of 27 months, local recurrence, regional lymph node metastasis, and distant metastasis were seen in 17 (30%), 12 (21%), and 17 (30%) of the 57 patients, respectively. The 3-year overall survival rate was 63.4%. SUV{sub max} did not affect any recurrence, DFS, OS, or CSS. RI significantly predicted higher distant metastasis (HR 47.546, p = 0.026). In contrast, RI tended to predict lower local recurrence (HR 0.175, p = 0.246) and regional lymph node metastasis (HR 0.109, p = 0.115). Conclusions: SUV{sub max} at staging FDG-PET does not predict any recurrence, DFS, OS or CSS. In contrast, higher RI predicts higher distant metastasis and tended to predict lower local or regional lymph node metastasis.

    To explore whether pre-reoperative dynamic contrast-enhanced (DCE)-MRI findings correlate with clinical outcome in patients who undergo surgical treatment for recurrent rectal carcinoma. A retrospective study of DCE-MRI in patients with recurrent rectal cancer was performed after obtaining an IRB waiver. We queried our PACS from 1998 to 2012 for examinations performed for recurrent disease. Two radiologists in consensus outlined tumour regions of interest on perfusion images. We explored the correlation between K{sup trans}, K{sub ep}, V{sub e}, AUC90 and AUC180 with time to re-recurrence of tumour, overall survival and resection margin status. Univariate Cox PH models were used for survival, while univariate logistic regression was used for margin status. Among 58 patients with pre-treatment DCE-MRI who underwent resection, 36 went directly to surgery and 18 had positive margins. K{sup trans} (0.55, P = 0.012) and K{sub ep} (0.93, P = 0.04) were inversely correlated with positive margins. No significant correlations were noted between K{sup trans}, K{sub ep}, V{sub e}, AUC90 and AUC180 and overall survival or time to re-recurrence of tumour. K{sup trans} and K{sub ep} were significantly associated with clear resection margins; however overall survival and time to re-recurrence were not predicted. Such information might be helpful for treatment individualisation and deserves further investigation. (orig.)

    Full Text Available Background: Bevacizumab has been increasingly used in combination chemotherapy with paclitaxel for treatment of metastatic or recurrent breast cancer. The aim of this report is to underline possible risks associated with the new combination chemotherapy. Case Presentation: A 39-year-old woman with recurrent breast cancer was treated with bevacizumab and paclitaxel. Positron emission tomography revealed breast cancer metastasis to the left supraclavicular lymph nodes and right axillary lymph nodes, with no distant metastasis. Results: After the third cycle of bevacizumab and paclitaxel, the patient developed a bloody bowel discharge. Emergent colonoscopy demonstrated diverticular bleeding on one of the multiple diverticula in the ascending colon. The bleeding point was successfully clipped colonoscopically. Conclusion: The factors for diverticular bleeding are believed to be non-steroidal anti-inflammatory drugs, constipation, and bevacizumab. We recommend reviewing anamneses for diverticulitis, multiple prior abdominal surgeries, peritoneal carcinomatosis, and regular use of certain drugs.

    Hepatic ischemia/reperfusion (I/R) injury is a common clinical challenge. Despite accumulating evidence regarding its mechanisms and potential therapeutic approaches, hepatic I/R is still a leading cause of organ dysfunction, morbidity, and resource utilization, especially in those patients with underlying parenchymal abnormalities. In the oncological setting, there are growing concerns regarding the deleterious impact of I/R injury on the risk of post-surgical tumor recurrence. This review aims at giving the last updates regarding the role of hepatic I/R and liver parenchymal quality injury in the setting of oncological liver surgery, using a "bench-to-bedside" approach. Relevant medical literature was identified by searching PubMed and hand scanning of the reference lists of articles considered for inclusion. Numerous preclinical models have depicted the impact of I/R injury and hepatic parenchymal quality (steatosis, age) on increased cancer growth in the injured liver. Putative pathophysiological mechanisms linking I/R injury and liver cancer recurrence include an increased implantation of circulating cancer cells in the ischemic liver and the upregulation of proliferation and angiogenic factors following the ischemic insult. Although limited, there is growing clinical evidence that I/R injury and liver quality are associated with the risk of post-surgical cancer recurrence. In conclusion, on top of its harmful early impact on organ function, I/R injury is linked to increased tumor growth. Therapeutic strategies tackling I/R injury could not only improve post-surgical organ function, but also allow a reduction in the risk of cancer recurrence.

    2008-01-01

    The aim of this study was to review published reports on the feasability, results, and reliability of sentinel node biopsy in cases of ipsilateral recurrent breast cancer. A Medline search on publications from January 1999 to December 2007 and cross-references in published articles were looked for. We identified 16 reports on sentinel node biopsy in recurrent breast cancer, including a total of 287 patients. In 210/287 (73.2%) a sentinel node was identified, 77/210 (37.7%) had had previous axillary lymph node dissection and 131 (62.3%) a previous sentinel node procedure. Aberrant lymphatic drainage, other than the ipsilateral axilla was noted in 68/210 (32.4%). Of these 16/68 (23.6%) were located in the contralateral axilla. Of the removed contralateral axillary sentinel nodes 8/17 (47.1%) were invaded by cancer. We conclude that sentinel node biopsy in cases of recurrent ipsilateral breast cancer is feasible. In about one out of three cases drainage to the contralateral axilla with invasion in almost half the cases takes place. The therapeutical consequences of these findings need further study.

    Full Text Available Background. Regional lymph node recurrence (RLNR is common in patients with thyroid cancer but clinicopathological predictors are unclear. We aimed to clarify these predictors and identify patients who would benefit from prophylactic lymph node dissection the most. Method. 343 patients with different types of thyroid cancer were analyzed retrospectively. All patients underwent total thyroidectomy between 2007 and 2013. Results. The median ± interquartile range of patients’ age was 40 ± 25 years. 245 (71.4% patients were female. Regarding the risk of regional lymph node recurrence, we found that male gender, age ≥45 years, non-PTC (i.e., medullary, follicular, and anaplastic types histopathology, T3 (i.e., tumor size >4 cm in the greatest dimension limited to the thyroid or any tumor with minimal extrathyroid extension, stage IVa, and isolated cervical lymphadenopathy as initial manifestation (ICL are significant risk factors. T3 (p < 0.001; odds ratio = 156.41, 95% CI [55.72–439.1] and ICL (p < 0.001; odds ratio = 77.79, 95% CI [31.55–191.81] were the strongest predictors of regional lymph node recurrence. Conclusion. We found easily achievable risk factors for RLNR in thyroid cancers patients. We suggested that patients with specific clinicopathological features like male gender, age ≥45 years, larger tumor size, and extrathyroidal extension be considered as prophylactic lymphadenectomy candidates.

    Background: Colorectal cancer (CRC) is a common malignancyworldwide and its outcome is most closely related to the extent of disease at presentation. Early diagnosis of an asymptomatic recurrence increases the likelihood of a complete surgical resection. Objectives: The aim of this study was to evaluate the incidence of colorectal cancer recurrence and survival rate within 5 years, after surgery. Patients and Methods: During the 9-year period since 21st Mar, 2004 to 20th Mar, 2013, patients whose primary colorectal cancer were resected in Taleghani hospital, Tehran, Iran were selected in a historical cohort. The necessary data such as demographic, age, gender, family history of CRC, site and size of tumor, stage of tumor, operation details, histological results, treatment method, histopathologic, etc. were collected. Then the recurrence and survival of colorectal cancer within 5 years after operation and their risk factors were evaluated. P value less than 0.05 were considered significant. All analysis was done using SPSS software. Results: A total of 107 patients underwent resection for colorectal cancer during the study period, with mean age of 53.50 ± 12.68 years (range 24 - 76 years), survival rate of 73.8% (rectum 70.0% and colon 75.9%), and mean survival time of 142.17 ± 21.60 month. The recurrence rate of CRC patients, during five years after surgery was 5.7%. Regional lymph nodes, Distance metastasis and Adjuvant therapy were significant prognosis factors of survival after surgery. Conclusions: The rate of recurrence in Iranian patients was low, which could be due to improvement of exactness and expertise of surgeons or better adjuvant therapy. The significant association between survival and adjuvant therapy clarifies this finding. Early diagnosis and primary detection could increase the rate of survival. PMID:26478796

    To update the practical guidelines for radiotherapy of patients with locoregional breast cancer recurrences based on the current German interdisciplinary S3 guidelines 2012. A comprehensive survey of the literature using the search phrases ''locoregional breast cancer recurrence'', ''chest wall recurrence'', ''local recurrence'', ''regional recurrence'', and ''breast cancer'' was performed, using the limits ''clinical trials'', ''randomized trials'', ''meta-analysis'', ''systematic review'', and ''guidelines''. Patients with isolated in-breast or regional breast cancer recurrences should be treated with curative intent. Mastectomy is the standard of care for patients with ipsilateral breast tumor recurrence. In a subset of patients, a second breast conservation followed by partial breast irradiation (PBI) is an appropriate alternative to mastectomy. If a second breast conservation is performed, additional irradiation should be mandatory. The largest reirradiation experience base exists for multicatheter brachytherapy; however, prospective clinical trials are needed to clearly define selection criteria, long-term local control, and toxicity. Following primary mastectomy, patients with resectable locoregional breast cancer recurrences should receive multimodality therapy including systemic therapy, surgery, and radiation +/- hyperthermia. This approach results in high local control rates and long-term survival is achieved in a subset of patients. In radiation-naive patients with unresectable locoregional recurrences, radiation therapy is mandatory. In previously irradiated patients with a high risk of a second local recurrence after surgical resection or in patients with unresectable recurrences, reirradiation should be strongly considered.

  16. Factors influencing local recurrence after excision and radiotherapy for primary breast cancer

    International Nuclear Information System (INIS)

    Between November 1979 and December 1986, 262 patients were treated for primary breast cancer by local excision and radiotherapy at the City Hospital, Nottingham. Local recurrence within the treated breast occurred in 56 patients (21 per cent), in 18 (6.8 per cent) of whom it was gross and uncontrollable. Analysis of clinicopathological features shows patient age, nodal status, tumour size, presence of definitive vascular invasion, adjacent ductal carcinoma in situ and grade to be predictive of local recurrence. A Cox's multivariate analysis of these factors shows the first four to be independently significant. The factors can be combined as a prognostic index which allows identification of patients at high risk of local recurrence. On the basis of these findings the authors altered their selection policy for patients suitable for breast conservation. (author)

    2011-05-01

    Full Text Available Abstract Background To assess the clinical outcome of chemoradiotherapy with or without surgery for locally recurrent rectal cancer (LRRC and to find useful and significant prognostic factors for a clinical situation. Methods Between January 2001 and February 2009, 67 LRRC patients, who entered into concurrent chemoradiotherapy with or without surgery, were reviewed retrospectively. Of the 67 patients, 45 were treated with chemoradiotherapy plus surgery, and the remaining 22 were treated with chemoradiotherapy alone. The mean radiation doses (biologically equivalent dose in 2-Gy fractions were 54.6 Gy and 66.5 Gy for the chemoradiotherapy with and without surgery groups, respectively. Results The median survival duration of all patients was 59 months. Five-year overall (OS, relapse-free (RFS, locoregional relapse-free (LRFS, and distant metastasis-free survival (DMFS were 48.9%, 31.6%, 66.4%, and 40.6%, respectively. A multivariate analysis demonstrated that the presence of symptoms was an independent prognostic factor influencing OS, RFS, LRFS, and DMFS. No statistically significant difference was found in OS (p = 0.181, RFS (p = 0.113, LRFS (p = 0.379, or DMFS (p = 0.335 when comparing clinical outcomes between the chemoradiotherapy with and without surgery groups. Conclusions Chemoradiotherapy with or without surgery could be a potential option for an LRRC cure, and the symptoms related to LRRC were a significant prognostic factor predicting poor clinical outcome. The chemoradiotherapy scheme for LRRC patients should be adjusted to the possibility of resectability and risk of local failure to focus on local control.

    Purpose Although overall there is a positive association between obesity and risk of prostate cancer (PrCa) recurrence, results of individual studies are somewhat inconsistent. We investigated whether the failure to exclude diabetics in prior studies could have increased the likelihood of conflicting results. Methods A total of 610 PrCa patients who underwent radical prostatectomy between 2005 and 2012 were followed for recurrence, defined as a rise in serum PSA ≥ 0.2 ng/ml following surgery. Body mass index (BMI) and history of type 2 diabetes were documented prior to PrCa surgery. The analysis was conducted using Cox proportional hazard models. Results Obesity (25.6 %) and diabetes (18.7 %) were common in this cohort. There were 87 (14.3 %) recurrence events during a median follow-up of 30.8 months after surgery among the 610 patients. When analyzed among all PrCa patients, no association was observed between BMI/obesity and PrCa recurrence. However, when analysis was limited to non-diabetics, obese men had a 2.27-fold increased risk (95 % CI 1.17–4.41) of PrCa recurrence relative to normal weight men, after adjusting for age and clinical/pathological tumor characteristics. Conclusions This study found a greater than twofold association between obesity/BMI and PrCa recurrence in non-diabetics. We anticipated these results because the relationship between BMI/obesity and the biologic factors that may underlie the PrCa recurrence–BMI/obesity association, such as insulin, may be altered by the use of anti-diabetes medication or diminished beta-cell insulin production in advanced diabetes. Studies to further assess the molecular factors that explain the BMI/obesity–PrCa recurrence relationship are warranted. PMID:25771797

    Aim: To examine the impact and prognostic significance of α-tocopherol associated protein (TAP) expression in a series of prostate cancer patients. Methods: Tissues from 87 patients underwent radical prostatectomy were examined for TAP expression by immunohistochemistry. The relationships of the staining results, the clinic pathological characteristics and the recurrence times were analyzed. Results: Compared with the adjacent areas of normal and benign glands,immunoreactivity of TAP was reduced in areas of prostate cancer. A lower TAP-positive cell number per mm2 of the largest cancer area (defined as TAP-PN) was associated with higher clinical stage (r = -0.248, P = 0.0322). Inverse associations were found among the TAP-PN and positive lymph nodes (r = -0.231, P = 0.0325), preoperative prostatespecific antigen (PSA) levels (r =-0.423, P = 0.0043), tumor size (r =-0.315, P = 0.0210) and elevated tumor cell proliferation, which was indicated by the staining of Ki-67 (r = -0.308, P = 0.0026). TAP-PN was a significant predictorof recurrence univariately (P = 0.0006), as well as multivariately, adjusted for known markers including preoperative PSA, clinical stage, Gleason score, surgical margin, extra-prostatic extension, seminal vesicle invasion and lymph node metastasis (P = 0.0012). Conclusion: Reduced expression of TAP was associated with the cell proliferation status of prostate cancer, adverse pathological parameters and the increased risk of recurrence.

    Space radiation presents major challenges to astronauts on the International Space Station and for future missions to the Earth s moon or Mars. Methods used to project risks on Earth need to be modified because of the large uncertainties in projecting cancer risks from space radiation, and thus impact safety factors. We describe NASA s unique approach to radiation safety that applies uncertainty based criteria within the occupational health program for astronauts: The two terrestrial criteria of a point estimate of maximum acceptable level of risk and application of the principle of As Low As Reasonably Achievable (ALARA) are supplemented by a third requirement that protects against risk projection uncertainties using the upper 95% confidence level (CL) in the radiation cancer projection model. NASA s acceptable level of risk for ISS and their new lunar program have been set at the point-estimate of a 3-percent risk of exposure induced death (REID). Tissue-averaged organ dose-equivalents are combined with age at exposure and gender-dependent risk coefficients to project the cumulative occupational radiation risks incurred by astronauts. The 95% CL criteria in practice is a stronger criterion than ALARA, but not an absolute cut-off as is applied to a point projection of a 3% REID. We describe the most recent astronaut dose limits, and present a historical review of astronaut organ doses estimates from the Mercury through the current ISS program, and future projections for lunar and Mars missions. NASA s 95% CL criteria is linked to a vibrant ground based radiobiology program investigating the radiobiology of high-energy protons and heavy ions. The near-term goal of research is new knowledge leading to the reduction of uncertainties in projection models. Risk projections involve a product of many biological and physical factors, each of which has a differential range of uncertainty due to lack of data and knowledge.

    Breast cancer is common with over 230,000 new cases diagnosed each year in North America alone. While great strides have been made to achieve excellent cancer control and survival, a significant minority of patients fail locally. While initial salvage to regain disease control is of the utmost importance, it is not universally successful. This leads to a therapeutic quagmire. Additional surgery, radiation and chemo-hormonal therapy are possible, but they are usually highly morbid with low success rates. Photodynamic therapy appears to be an underutilized salvage modality for this unfortunate patient population. This report analyzes and reviews the role of photodynamic therapy for patients with chest wall re-recurrence from breast cancer.

    In this study we explore the ability of a novel machine learning approach, in conjunction with computer-extracted features describing prostate cancer morphology on pre-treatment MRI, to predict whether a patient will develop biochemical recurrence within ten years of radiation therapy. Biochemical recurrence, which is characterized by a rise in serum prostate-specific antigen (PSA) of at least 2 ng/mL above the nadir PSA, is associated with increased risk of metastasis and prostate cancer-related mortality. Currently, risk of biochemical recurrence is predicted by the Kattan nomogram, which incorporates several clinical factors to predict the probability of recurrence-free survival following radiation therapy (but has limited prediction accuracy). Semantic attributes on T2w MRI, such as the presence of extracapsular extension and seminal vesicle invasion and surrogate measure- ments of tumor size, have also been shown to be predictive of biochemical recurrence risk. While the correlation between biochemical recurrence and factors like tumor stage, Gleason grade, and extracapsular spread are well- documented, it is less clear how to predict biochemical recurrence in the absence of extracapsular spread and for small tumors fully contained in the capsule. Computer{extracted texture features, which quantitatively de- scribe tumor micro-architecture and morphology on MRI, have been shown to provide clues about a tumor's aggressiveness. However, while computer{extracted features have been employed for predicting cancer presence and grade, they have not been evaluated in the context of predicting risk of biochemical recurrence. This work seeks to evaluate the role of computer-extracted texture features in predicting risk of biochemical recurrence on a cohort of sixteen patients who underwent pre{treatment 1.5 Tesla (T) T2w MRI. We extract a combination of first-order statistical, gradient, co-occurrence, and Gabor wavelet features from T2w MRI. To identify which of these

  13. Can anaesthetic and analgesic techniques affect cancer recurrence or metastasis?

    LENUS (Irish Health Repository)

    Heaney, A

    2012-12-01

    Summary Cancer is a leading cause of morbidity and mortality worldwide and the ratio of incidence is increasing. Mortality usually results from recurrence or metastases. Surgical removal of the primary tumour is the mainstay of treatment, but this is associated with inadvertent dispersal of neoplastic cells into the blood and lymphatic systems. The fate of the dispersed cells depends on the balance of perioperative factors promoting tumour survival and growth (including surgery per se, many anaesthetics per se, acute postoperative pain, and opioid analgesics) together with the perioperative immune status of the patient. Available evidence from experimental cell culture and live animal data on these factors are summarized, together with clinical evidence from retrospective studies. Taken together, current data are sufficient only to generate a hypothesis that an anaesthetic technique during primary cancer surgery could affect recurrence or metastases, but a causal link can only be proved by prospective, randomized, clinical trials. Many are ongoing, but definitive results might not emerge for a further 5 yr or longer. Meanwhile, there is no hard evidence to support altering anaesthetic technique in cancer patients, pending the outcome of the ongoing clinical trials.

    To investigate the use of minimally invasive high-intensity focused ultrasound (HIFU) as a salvage therapy in men with localized prostate cancer recurrence following external beam radiotherapy (EBRT), brachytherapy or proton therapy. A review of 20 cases treated using the Sonablate® 500 HIFU device, between August 28, 2002 and September 1, 2009, was carried out. All men had presumed organ-confined, histologically confirmed recurrent prostate adenocarcinoma following radiation therapy. All men with presumed, organ-confined, recurrent disease following EBRT in 8 patients, brachytherapy in 7 patients or proton therapy in 5 patients treated with salvage HIFU were included. The patients were followed for a mean (range) of 16.0 (3-80) months. Biochemical disease-free survival (bDFS) rates in patients with low-intermediate and high risk groups were 86% and 50%, respectively. Side-effects included urethral stricture in 2 of the 16 patients (13%), urinary tract infection or dysuria syndrome in eight (26%), and urinary incontinence in one (6%). Recto-urethral fistula occurred in one patient (6%). Transrectal HIFU is an effective treatment for recurrence after radiotherapy especially in patients with low- and intermediate risk groups.

    Regional silicone gel migration from a ruptured breast implant has been reported at different locations including the upper extremity, chest wall muscles, axilla and back. We report a patient who presented with an axillary mass that mimicked a regional recurrence 5 years after breast cancer reconstruction with a latissimus dorsi musculocutaneous flap and silicon gel expander-prosthesis. Surgical exploration revealed that the mass contained silicone gel around the port of the breast expander that had ruptured. The mass was confluent with an intracapsular silicone leak through a tract along the tube of the expander port.

  16. Management of Biochemical Recurrence after Primary Localized Therapy for Prostate Cancer

    2012-05-01

    Full Text Available Clinically localized prostate cancer is typically managed by well established therapies like radical prostatectomy, brachytherapy and external beam radiation therapy. While many patients can be cured with definitive local therapy, some will have biochemical recurrence (BCR of disease detected by a rising serum prostate-specific antigen (PSA. Management of these patients is nuanced and controversial. The natural history indicates that a majority of patients with BCR will not die from prostate cancer but from other causes. Despite this, a vast majority of patients with BCR are empirically treated with non-curable systemic androgen deprivation therapy, with its myriad of real and potential side effects. In this review article, we examined the very definition of BCR after definitive local therapy, the current status of imaging studies in its evaluation, the need for additional therapies and the factors involved in the decision making in the choice of additional therapies. This review aims to help clinicians with the management of patients with BCR. The assessment of prognostic factors including absolute PSA level, time to recurrence, PSA kinetics, multivariable nomograms, imaging, and biopsy of the prostatic bed may help stratify the patients into localized or systemic recurrence. Patients with low risk of systemic disease may be cured by a salvage local therapy, while those with higher risk of systemic disease may be offered the option of androgen deprivation therapy or a clinical trial. An algorithm incorporating these factors is presented.

    Sentinel lymph node detection (SLND) with radiocolloid has become widely used for evaluation of nodal metastasis in primary breast cancer. However, the procedure for recurrent breast cancer is not well established. Contralateral axillary node metastasis is uncommon. We report 2 cases of contralateral axillary node metastasis with recurrent breast cancer. In the first case, contralateral node metastasis was found by SLND. In the other case without SLND, contralateral node metastasis developed after resection of local recurrence. FDG-avid contralateral node was pathologically diagnosed as metastasis. The SLND might be useful in patients with local recurrence after conservative breast cancer surgery. PMID:24368539

    2016-10-01

    Conventional cancer therapies involve the systemic delivery of anticancer agents that neither discriminate between cancer and normal cells nor eliminate the risk of cancer recurrence. Here, we demonstrate that the combination of gene, drug and phototherapy delivered through a prophylactic hydrogel patch leads, in a colon cancer mouse model, to complete tumour remission when applied to non-resected tumours and to the absence of tumour recurrence when applied following tumour resection. The adhesive hydrogel patch enhanced the stability and provided local delivery of embedded nanoparticles. Spherical gold nanoparticles were used as a first wave of treatment to deliver siRNAs against Kras, a key oncogene driver, and rod-shaped gold nanoparticles mediated the conversion of near-infrared radiation into heat, causing the release of a chemotherapeutic as well as thermally induced cell damage. This local, triple-combination therapy can be adapted to other cancer cell types and to molecular targets associated with disease progression.

    Full Text Available Bidirectional Associative Memories (BAMs based on first model proposed by Kosko do not have perfect recall of training set, and their algorithm must iterate until it reaches a stable state. In this work, we use the model of Alpha-Beta BAM to classify automatically cancer recurrence in female patients with a previous breast cancer surgery. Alpha-Beta BAM presents perfect recall of all the training patterns and it has a one-shot algorithm; these advantages make to Alpha-Beta BAM a suitable tool for classification. We use data from Haberman database, and leave-one-out algorithm was applied to analyze the performance of our model as classifier. We obtain a percentage of classification of 99.98%.

    Between 1986 and 1992, 10 patients (12 lesions) of advanced breast cancer were treated with multidisciplinary treatment including brachytherapy. The lesions treated included 5 primary breast tumors, 3 metastatic lesions in the contra lateral breast, 2 recurrences after external beam irradiation, 1 metastasis to the axillary lymph node and 1 metastasis to the upper arm skin. The interstitial irradiation techniques used were [sup 192]Ir low dose-rate irradiation for 5 lesions and high dose-rate for 7 lesions (including 3 with mould irradiation). External hyperthermia as performed for 6 lesions and interstitial hyperthermia were performed for 4 lesions. The local response was CR for 3 lesions, PRa for 8 lesions, PRb for 1 lesion with the local response rate being 100%. Excellent local control could be achieved by combination external and interstitial irradiation, indicating that radiotherapy is definitely useful for the treatment of advanced breast cancer.

    2016-08-01

    Several multi-gene assays have been developed to predict the risk of recurrence in patients with estrogen receptor-positive early breast cancer and in whom endocrine therapy is planned. The 21-gene assay is widely used and its prognostic value has been retrospectively validated, showing significant differences in the risk of distant recurrence for patients at high versus low risk. Its role in predicting chemotherapy benefit has also been established, showing a clear benefit for high-risk patients and minimal benefit in those at low risk. These findings have been prospectively investigated in TAILORx (Trial Assigning Individualized Options for Treatment), where available data from the low-risk cohort confirms the prognostic value of this diagnostic test. The prognostic utility of the 21-gene assay increases when combined with clinicopathologic variables, and data from integrated models suggest that its use should be limited to patients with tumor characteristics suggestive of potential chemotherapy benefit. Furthermore, the 21-gene assay has been shown to impact clinical decision making in a cost-effective manner, although direct evidence of benefit from modified treatment recommendations is yet to be proven. The prognostic value of this test has also been shown in populations with node-positive or locally advanced disease treated with neoadjuvant chemotherapy, and ongoing trials aim to prospectively validate these findings.

    2013-03-15

    Purpose: This study is designed to validate a previously developed locoregional recurrence risk (LRR) scoring system and further define which groups of patients with breast cancer would benefit from postmastectomy radiation therapy (PMRT). Methods and Materials: An LRR risk scoring system was developed previously at our institution using breast cancer patients initially treated with modified radical mastectomy between 1990 and 2001. The LRR score comprised 4 factors: patient age, lymphovascular invasion, estrogen receptor negativity, and number of involved lymph nodes. We sought to validate the original study by examining a new dataset of 1545 patients treated between 2002 and 2007. Results: The 1545 patients were scored according to the previously developed criteria: 920 (59.6%) were low risk (score 0-1), 493 (31.9%) intermediate risk (score 2-3), and 132 (8.5%) were high risk (score ≥4). The 5-year locoregional control rates with and without PMRT in low-risk, intermediate-risk, and high-risk groups were 98% versus 97% (P=.41), 97% versus 91% (P=.0005), and 89% versus 50% (P=.0002) respectively. Conclusions: This analysis of an additional 1545 patients treated between 2002 and 2007 validates our previously reported LRR scoring system and suggests appropriate patients for whom PMRT will be beneficial. Independent validation of this scoring system by other institutions is recommended.

    Yan Lu

    Full Text Available About 30% stage I non-small cell lung cancer (NSCLC patients undergoing resection will recur. Robust prognostic markers are required to better manage therapy options. The purpose of this study is to develop and validate a novel gene-expression signature that can predict tumor recurrence of stage I NSCLC patients. Cox proportional hazards regression analysis was performed to identify recurrence-related genes and a partial Cox regression model was used to generate a gene signature of recurrence in the training dataset -142 stage I lung adenocarcinomas without adjunctive therapy from the Director's Challenge Consortium. Four independent validation datasets, including GSE5843, GSE8894, and two other datasets provided by Mayo Clinic and Washington University, were used to assess the prediction accuracy by calculating the correlation between risk score estimated from gene expression and real recurrence-free survival time and AUC of time-dependent ROC analysis. Pathway-based survival analyses were also performed. 104 probesets correlated with recurrence in the training dataset. They are enriched in cell adhesion, apoptosis and regulation of cell proliferation. A 51-gene expression signature was identified to distinguish patients likely to develop tumor recurrence (Dxy = -0.83, P85%. Multiple pathways including leukocyte transendothelial migration and cell adhesion were highly correlated with recurrence-free survival. The gene signature is highly predictive of recurrence in stage I NSCLC patients, which has important prognostic and therapeutic implications for the future management of these patients.

    Full Text Available Abstract Background Breast cancer survivors often encounter physiological and psychological problems related to their diagnosis and treatment that can influence long-term prognosis. The aim of this research is to investigate the effects of a lifestyle intervention on body weight and psychological well-being in women recovering from breast cancer treatment, and to determine the relationship between changes in these variables and biomarkers associated with disease recurrence and survival. Methods/design Following ethical approval, a total of 100 patients will be randomly assigned to a lifestyle intervention (incorporating dietary energy restriction in conjunction with aerobic exercise training or normal care control group. Patients randomised to the dietary and exercise intervention will be given individualised healthy eating dietary advice and written information and attend moderate intensity aerobic exercise sessions on three to five days per week for a period of 24 weeks. The aim of this strategy is to induce a steady weight loss of up to 0.5 Kg each week. In addition, the overall quality of the diet will be examined with a view to (i reducing the dietary intake of fat to ~25% of the total calories, (ii eating at least 5 portions of fruit and vegetables a day, (iii increasing the intake of fibre and reducing refined carbohydrates, and (iv taking moderate amounts of alcohol. Outcome measures will include body weight and body composition, psychological health status (stress and depression, cardiorespiratory fitness and quality of life. In addition, biomarkers associated with disease recurrence, including stress hormones, estrogen status, inflammatory markers and indices of innate and adaptive immune function will be monitored. Discussion This research will provide valuable information on the effectiveness of a practical, easily implemented lifestyle intervention for evoking positive effects on body weight and psychological well-being, two

    Gastric cancer (GC) is the second leading cause of death from cancer globally. The most common cause of GC is the infection of Helicobacter pylori, but ∼11% of cases are caused by genetic factors. However, recurrences occur in approximately one-third of stage II GC patients, even if they are treated with adjuvant chemotherapy or chemoradiotherapy. This is potentially due to expression variation of genes; some candidate prognostic genes were identified in patients with high-risk recurrences. The objective of this study was to develop an effective computational method for meaningfully interpreting these GC-related genes and accurately predicting novel prognostic genes for high-risk recurrence patients. We employed properties of genes (gene ontology [GO] and KEGG pathway information) as features to characterize GC-related genes. We obtained an optimal set of features for interpreting these genes. By applying the minimum redundancy maximum relevance algorithm, we predicted the GC-related genes. With the same approach, we further predicted the genes for the prognostic of high-risk recurrence. We obtained 1104 GO terms and KEGG pathways and 530 GO terms and KEGG pathways, respectively, that characterized GC-related genes and recurrence-related genes well. Finally, three novel prognostic genes were predicted to help supplement genetic markers of high-risk GC patients for recurrence after surgery. An in-depth text mining indicated that the results are quite consistent with previous knowledge. Survival analysis of patients confirmed the novel prognostic genes as markers. By analyzing the related genes, we developed a systematic method to interpret the possible underlying mechanism of GC. The novel prognostic genes facilitate the understanding and therapy of GC recurrences after surgery. PMID:26154702

  13. CT guided 125I seed brachytherapy for recurrent rectum cancer

    International Nuclear Information System (INIS)

    Objective: To investigate the technological feasibility, efficacy and morbidity of CT guided 125I seed implantation for recurrent rectum cancer. Methods: Twenty-three patients with recurrent rectum cancer were treated with CT guided interstitial 125I seed brachytherapy. In 20 patients the procedure was performed under epidural anesthesia and 3 patients under local anesthesia. Treatment planning system was used to calculate the number of seeds, the space distribution and the introduction of the seeding needles. Matched peripheral dose (MPD) of 121I seed implantation ranged from 90-120 Gy for patients who had had external radiotherapy, and 140- 160 Gy for those who had not. The planning target volume(PTV) was clinical target volume(CTV) plus 1 cm margin. The range of radioactivity of the 125I seeds was 18.5-25.9 MBq. All these 23 patients had CT scan at 5 mm intervals after implantation for quality evaluation, together with routine chest, pelvic X-ray films within 24-48 hours after seed implantation. Three patients received three-dimensional conformal radiation therapy(3DCRT) to a total dose of 45-50 Gy, with 2-3 Gy/f. Follow-up time was from 3 to 28 months. Results: All patients was able to tolerate seed implantation well. Complete pain relief was observed in 12/15, and partial relief in 2/15 and no response in 1/15, with a response rate of 93%. The local control rate was 87%. The 1- and 2-year survival rate was 93% and 50% respectively. Two of four patients have died of dissemination to the lung after 8 and 12 months. One seed has migrated into the pelvis without causing any untoward morbidity. Conclusion: CT guided 125I seed implantation for recurrent rectum cancer is safe, minimally invasive, causing only mild morbidity. It possesses a high efficacy, yet it should be given in combination with extemal beam radiation and chemotherapy, should distant metastasis be observed. (authors)

    Diagnosis of breast cancer recurrence can be difficult as a result of the presence of scar tissue in the breast. Magnetic resonance imaging (MRI) may be superior to traditional imaging in diagnosis of recurrence because of its ability to differentiate malignancy from scarring. Current guidelines on investigation of suspected breast cancer recurrence recommend MRI when other investigations have equivocal findings. We performed the first systematic review on this topic.

    Full Text Available The incidence of anastomotic recurrence after curative resection of colorectal cancer is relatively low compared to that of other types of recurrence, such as hepatic, lung and local recurrence. However, almost all cases of anastomotic recurrence of colorectal cancer occur within 3 years after surgery. We experienced a rare case of anastomotic recurrence in whom colonoscopy revealed no signs of recurrence 3 years after surgery; however, anastomotic recurrence was detected over 5 years after surgery. A 60-year-old female with a history of surgery for cancer of the cecum in her forties underwent sigmoidectomy and right colectomy with D3 lymph node dissection for both stage IIA sigmoid colon cancer and stage IIA transverse colon cancer. Computed tomography and colonoscopy revealed no signs of recurrence 3 years after surgery; however, 5 years and 4 months after surgery, colonoscopy demonstrated surrounding flaring and swelling in the anastomotic area of the sigmoid colon, and a biopsy revealed an adenocarcinoma. Under the diagnosis of anastomotic recurrence over 5 years after surgery, lower anterior resection was performed. The patient has exhibited no other signs of recurrence in the 2 years since the last operation.

    AIM: To comprehend the risk factors of recurrence of hepatocellular carcinoma (HCC) and its relationship with the infection patterns of hepatitis B virus (HBV). METHODS: All materials of 270 cases of postoperative HCC were statistically analyzed by SPSS software. Recurrence and metastasis were classified into early (≤2 years) and late phase (>2 years). Risk factors for recurrence and metastasis after surgery in each group were analyzed.RESULTS: Out of 270 cases of HCC, 162 cases were followed up in which recurrence and metastasis occurred in 136 cases. There were a lot of risk factors related to recurrence and metastasis of HCC; risk factors contributing to early phase recurrence were serum AFP level, vascular invasion, incisal margin and operative transfusion, gross tumor classification and number of intrahepatic node to late phase recurrence. The HBV infective rate of recurrent HCC was 94.1%, in which "HBsAg, HBeAb, HBcAb" positive pattern reached 45.6%. The proportion of HBV infection in solitary large hepatocellular carcinoma (SLHCC) evidently decreased compared to nodular hepatocellular carcinoma (NHCC) (P<0.05).CONCLUSION: The early and late recurrence and metastasis after hepatectomy of HCC were associated with different risk factors. The early recurrence may be mediated by vascular invasion and remnant lesion, the late recurrence by tumor's clinical pathology propert, as multicentric carcinogenesis or intrahepatic carcinoma denovo. HBV replication takes a great role in this process. From this study, we found that SLHCC has more satisfactory neoplasm biological behavior than NHCC.

  1. Reirradiation of recurrent breast cancer with and without concurrent chemotherapy

    International Nuclear Information System (INIS)

    Treatment options for loco-regional recurrent breast cancer after previous irradiation are limited. The efficacy of chemotherapy might be hampered because of impaired tissue perfusion in preirradiated tissue. Thus, mastectomy or local excision and reconstructive surgery are the preferred treatments. However, in recent years evidence accumulates that a second breast conserving approach with reirradiation as part of the treatment might be feasible and safe and, furthermore, reirradiation might be an option for palliation. Here we report on the experience of a single community centre in reirradiation of recurrent breast cancer. The report is based on 29 patients treated with reirradiation. All data were prospectively collected. The median age was 63 years (range 35 to 82 yrs). The interval between initial diagnosis and diagnosis before start of reirradiation was 11.6 months to 295.5 months. The mean total dose (initial dose and reirradiation dose) was 106.2 Gy (range 80.4 to 126 Gy) and the mean BED3 Gy 168,5 Gy (range 130,6 to 201,6). The mean interval between initial radiotherapy and reirradiation was 92.9 months (range 8.7 to 290.1). Inoperable or incompletely resected patients were offered concurrent chemotherapy with either 5-FU or capecitabine. All patients received 3D-conformal radiotherapy with 1.6 to 2.5 Gy/fraction five times weekly. The treatment volume comprised all visible lesions or lesions detectable on CT/MRI/FDG-PET/CT or the tumour bed or recurrent tumour. The local progression-free survival of all patients at one and two years was 81% and 63%. Patients who had no surgery of the recurrence (16/29) had local progression-free survival at one and two years of 72% and 25% with a median progression-free survival time of 17 months. Partial remission and good symptom relief was achieved in 56% (9/16) or complete response of symptoms and/or tumour in 44% (7/16). Patients who had no distant metastases and had at least an R1-resection had a local progression

  3. Association of genetic variants in VEGF-A with clinical recurrence in prostate cancer patients treated with definitive radiotherapy

    International Nuclear Information System (INIS)

    Vascular endothelial growth factor-A (VEGF-A), a key regulator of tumor-induced angiogenesis, is critical for tumor growth and metastasization. The goal of the present study was to evaluate the prognostic value of VEGF single nucleotide polymorphisms (SNPs) and haplotypes for clinical recurrence after definitive radiotherapy for prostate cancer. The association of seven VEGF-A polymorphisms and their haplotypes with clinical recurrence (defined as the occurrence of local recurrence and/or distant metastases) in 496 prostate cancer patients treated with definitive radiotherapy were investigated. Genotypes were determined by 5'-nuclease (TaqMan) assays; haplotypes were analyzed using the Haploview program. Within a median follow-up time of 80 months, 44 patients (9%) developed clinical recurrences. Haplotype analysis showed two separate blocks of high-linkage disequilibrium, formed by five polymorphisms (-2578C > A, -2489C > T, -1498C > T, -634G > C, -7C > T) upstream of the coding sequence (CCCCC, ATTGC, CCCGC, ATTGT) and two polymorphisms (936C > T, 1612G > A) downstream of the coding sequence (CA, CG, TG). Carriers of at least 1 copy of the ATTGC haplotype were at higher risk of recurrence (hazard ratio [HR] 3.83; 95%CI 1.48-9.90, p=0.006); for carriers of 2 copies, the HR was 4.85 (95%CI 1.72-13.6; p=0.003). In multivariate analysis, patients harboring at least one copy of the ATTGC haplotype remained at increased risk of recurrence (HR 3.63, 95%CI 1.38-9.55, p=0.009); in patients carrying 2 copies, the HR was 4.72 (95%CI 1.64-13.6, p=0.004). Our findings indicate that the VEGF-A ATTGC haplotype may predict clinical recurrence in prostate cancer patients treated with radiotherapy. (orig.)

    . Risk factors for local recurrence (LR), distant metastases (DM), overall survival (OS), and cancer specific survival (CS) were identified by multivariate analyses. Results: A total of 1.125 patients had a median follow-up of 57 (25-93) months. Intraoperative perforation occurred in 108 (10......%). The cumulative 5-year LR rate was 11% (95% CI 7-13), OS was 56% (95% CI 53-60), and CS was 68% (95% CI 65-71). Multivariate analysis showed that perforation, tumour stage and non-radical surgery were independent risk factors for LR; tumour fixation, perforation and tumour stage were independent risk factors...... for DM, and risk factors for impaired OS and CS were age, tumour perforation, tumour stage, lymph node metastases and non-radical surgery. Conclusion: Intraoperative perforation is a major risk factor for local and distant recurrence and survival and should be avoided....

  17. Failure Rates and Patterns of Recurrence in Patients With Resected N1 Non-Small-Cell Lung Cancer

    International Nuclear Information System (INIS)

    Purpose: To examine the local and distant recurrence rates and patterns of failure in patients undergoing potentially curative resection of N1 non-small-cell lung cancer. Methods and Materials: The study included 60 consecutive unirradiated patients treated from 2000 to 2006. Median follow-up was 30 months. Failure rates were calculated by the Kaplan-Meier method. A univariate Cox proportional hazard model was used to assess factors associated with recurrence. Results: Local and distant failure rates (as the first site of failure) at 2, 3, and 5 years were 33%, 33%, and 46%; and 26%, 26%, and 32%, respectively. The most common site of local failure was in the mediastinum; 12 of 18 local recurrences would have been included within proposed postoperative radiotherapy fields. Patients who received chemotherapy were found to be at increased risk of local failure, whereas those who underwent pneumonectomy or who had more positive nodes had significantly increased risks of distant failure. Conclusions: Patients with resected non-small-cell lung cancer who have N1 disease are at substantial risk of local recurrence as the first site of relapse, which is greater than the risk of distant failure. The role of postoperative radiotherapy in such patients should be revisited in the era of adjuvant chemotherapy.

    Gastric cancer is caused by both genetic and environmental factors. A woman who suffered from recurrent candidiasis throughout her life developed diffuse-type gastric cancer at the age of 23 years. Using whole-exome sequencing we identified a germline homozygous missense variant in MYD88. Immunological assays on peripheral blood mononuclear cells revealed an impaired immune response upon stimulation with Candida albicans, characterized by a defective production of the cytokine interleukin-17. Our data suggest that a genetic defect in MYD88 results in an impaired immune response and may increase gastric cancer risk. PMID:26700889

    Although fear of recurrence is a major concern among breast cancer survivors after surgery, no standard strategies exist that alleviate their distress. This study examined the association of patients' problem-solving skills and fear of recurrence and psychological distress among breast cancer survivors. Randomly selected, ambulatory, female patients with breast cancer participated in this study. They were asked to complete the Concerns about Recurrence Scale (CARS) and the Hospital Anxiety and Depression Scale. Multiple regression analyses were used to examine their associations. Data were obtained from 317 patients. Patients' problem-solving skills were significantly associated with all subscales of fear of recurrence and overall worries measured by the CARS. In addition, patients' problem-solving skills were significantly associated with both their anxiety and depression. Our findings warrant clinical trials to investigate effectiveness of psychosocial intervention program, including enhancing patients' problem-solving skills and reducing fear of recurrence among breast cancer survivors.

    AIM: To investigate the clinicopathological risk factors for immediate post-operative fatal recurrence of hepatocellular carcinoma (HCC), which may have practical implication and contribute to establishing high risk patients for pre- or post-operative preventive measures against HCC recurrence.METHODS: From June 1994 to May 2004, 269 patients who received curative resection for HCC were reviewed.Of these patients, those who demonstrated diffuse intrahepatic or multiple systemic recurrent lesions within 6mo after surgery were investigated (fatal recurrence group). The remaining patients were designated as the control group, and the two groups were compared for clinicopathologic risk factors.RESULTS: Among the 269 patients reviewed, 30patients were enrolled in the fatal recurrence group.Among the latter, 20 patients showed diffuse intrahepatic recurrence type and 10 showed multiple systemic recurrence type. Multivariate analysis between the fatal recurrence group and control group showed that preoperative serum alpha-fetoprotein (AFP) level was greater than 1 000 μg/L (P=0.02; odds ratio= 2.98),tumor size greater than 6.5 cm (P=0.03; OR=2.98),and presence of microvascular invasion (P= 0.01;OR=4.89) were the risk factors in the fatal recurrence group. The 48.1% of the patients who had all the three risk factors and the 22% of those who had two risk factors experienced fatal recurrence within 6 mo after surgery.CONCLUSION: Three distinct risk factors for immediate post-operative fatal recurrence of HCC after curative resection are pre-operative serum AFP level>1 000 μg/L,tumor size>6.5 cm, and microvascular invasion. The high risk patients with two or more risk factors should be the candidates for various adjuvant clinical trials.

    Recent evidence shows that certain microRNAs (miRNAs) play a role in both obesity and prostate cancer recurrence,but the association between the expression of these miRNAs and obesity in prostate cancer recurrence is unknown.In this study,we examined the effect of the interaction between obesity and miR-21,miR-221 or miR-222 expression on prostate cancer recurrence among 28 recurrent and 37 non-recurrent prostate cancer cases,miRNA expression was determined using quantitative real-time polymerase chain reaction.Cox proportional hazard models adjusting for age at diagnosis,clinical stage and Gleason score were used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for recurrence free survival.A significantly (P=0.014) higher proportion of recurrent cases (78.6%) than non-recurrent cases (48.6%) had a low expression of miR-21 and the difference was more prominent in obese than non-obese patients.Multivariate analysis showed that the expression of miR-21 was an independent risk factor for recurrence in obese (HR=6.15,95% CI=1.04-36.48,P=0.045),but not in non-obese (HR=1.28,95% CI=0.30-5.49,P=0.74) cases.A significant association with recurrence was not observed for the expression of miR-221 and miR-222.In summary,our findings show that miR-21 is associated with prostate cancer recurrence after radical prostatectomy and suggest that the differential expression of miR-21 is more prominent in obese than in non-obese cases.Future larger studies are warranted to confirm these initial findings and to elucidate the mechanisms involved.

  5. Correlation of breast recurrence (inflammatory type or not) after breast conserving surgery with radiation therapy and clinicopathological factors in breast cancer

    International Nuclear Information System (INIS)

    To clarify risk factors for breast recurrence of inflammatory type after breast conserving therapy, we examined clinicopathological findings and therapies given after initial surgery. Nine cases of inflammatory breast recurrence out of 133 recurrent cases collected from a collaborative group supported by a grant-in-aid for Cancer Research by Japanese Ministry of Health and Welfare (7-24, Chairman: H. Koyama) were analyzed by a case control study. And forty-three recurrent cases in Kumamoto City Hospital were also analyzed similarly. Inflammatory breast recurrence after breast conserving surgery is characterized as follows: Most cases have negative surgical margin and may be unresponsive to radiation therapy, unlike non-inflammatory breast recurrence. Lymph node metastasis is involved in recurrence, but the difference in patients with only distant metastasis was positive lymphatic invasion. Distant metastasis coexisted at the time of recurrence, and secondary surgery was impossible in most cases. The prognosis after recurrence was unfavorable. These findings suggest that inflammatory recurrence is manifestation of so-called ''occult'' inflammatory breast cancer. (author)

    The poor outcome of patients with recurrent ovarian cancer constitutes a continuous challenge for decision-making in clinical practice. In this setting, molecular targets have recently been identified, and novel compounds are now available. Bevacizumab has been introduced for the treatment of patients with ovarian cancer and is, to date, the most extensively investigated targeted therapy in this setting. However, potential toxicities are associated with the use of this monoclonal antibody. These toxicities have been reported in clinical trials, and can also be observed outside of trials. As limited data is currently available regarding the safety of bevacizumab treatment in daily clinical practice, the current retrospective study was designed to evaluate this. Data from 156 patients with recurrent ovarian cancer who had received bevacizumab treatment between January 2006 and June 2009 were retrospectively identified from the institutional records of five French centers. In contrast to clinical trials, the patients in the present study were not selected and had a heterogeneous profile according to their prior medical history, lines of treatment prior to bevacizumab introduction and number of relapses. The results first confirm the effect of heavy pretreatment on the occurrence of serious and fatal adverse events in clinical practice, as previously reported for clinical trials and for other retrospective cohort studies. Importantly, the data also demonstrates, for the first time, that medical history of hypertension is an independent predictive risk factor for the development of high-grade hypertension during bevacizumab treatment. These results thus suggest that treating physicians must consider all risk factors for managing bevacizumab toxicity prior to its introduction. Such risk factors include the time of bevacizumab introduction, a patient's history of hypertension and a low incidence of pre-existing obstructive disease. PMID:26998090

    Our aim was to identify factors predisposing athletes to multiple stress fractures, with the emphasis on biomechanical factors. Our hypothesis was that certain anatomic factors of the ankle are associated with risk of multiple stress fractures of the lower extremities in athletes. Thirty-one athletes (19 men and 12 women) with at least three separate stress fractures each, and a control group of 15 athletes without fractures completed a questionnaire focusing on putative risk factors for stress fractures, such as nutrition, training history, and hormonal history in women. Bone mineral density was measured by dual-energy x-ray absorptiometry in the lumbar spine and proximal femur. Biomechanical features such as foot structure, pronation and supination of the ankle, dorsiflexion of the ankle, forefoot varus and valgus, leg-length inequality, range of hip rotation, simple and choice reaction times, and balance in standing were measured. There was an average of 3.7 (range, 3 to 6) fractures in each athlete, totaling 114 fractures. The fracture site was the tibia or fibula in 70% of the fractures in men and the foot and ankle in 50% of the fractures in women. Most of the patients were runners (61%); the mean weekly running mileage was 117 km. Biomechanical factors associated with multiple stress fractures were high longitudinal arch of the foot, leg-length inequality, and excessive forefoot varus. Nearly half of the female patients (40%) reported menstrual irregularities. Runners with high weekly training mileage were found to be at risk of recurrent stress fractures of the lower extremities.

    2016-01-01

    There are currently over 2.5 million breast cancer survivors in the United States and, according to the American Cancer Society, 10 to 20 percent of these women will develop recurrent breast cancer. Early detection of recurrence can avoid unnecessary radical treatment. However, self-examination or mammography screening may not discover a recurring cancer if the number of surviving cancer cells is small, while biopsy is too invasive and cannot be frequently repeated. It is therefore important to identify non-invasive biomarkers that can detect early recurrence. The present paper develops a mathematical model of cancer recurrence. The model, based on a system of partial differential equations, focuses on tissue biomarkers that include the plasminogen system. Among them, only uPAR is known to have significant correlation to its concentration in serum and could therefore be a good candidate for serum biomarker. The model includes uPAR and other associated cytokines and cells. It is assumed that the residual cancer cells that survived primary cancer therapy are concentrated in the same location within a region with a very small diameter. Model simulations establish a quantitative relation between the diameter of the growing cancer and the total uPAR mass in the cancer. This relation is used to identify uPAR as a potential serum biomarker for breast cancer recurrence.

  12. ACR Appropriateness Criteria Retreatment of Recurrent Head and Neck Cancer After Prior Definitive Radiation

    International Nuclear Information System (INIS)

    Recurrent and second primary head-and-neck squamous cell carcinomas arising within or in close proximity to previously irradiated fields are a common clinical challenge. Whereas surgical salvage therapy is recommended for resectable disease, randomized data support the role of postoperative reirradiation in high-risk patients. Definitive reirradiation is an established approach for patients with recurrent disease who are medically or technically inoperable or decline radical surgery. The American College of Radiology Expert Panel on Head and Neck Cancer reviewed the relevant literature addressing re-treatment after prior definitive radiation and developed appropriateness criteria for representative clinical scenarios. Examples of unresectable recurrent disease and microscopic residual disease after salvage surgery were addressed. The panel evaluated the appropriateness of reirradiation, the integration of concurrent chemotherapy, radiation technique, treatment volume, dose, and fractionation. The panel emphasized the importance of patient selection and recommended evaluation and treatment at tertiary-care centers with a head-and-neck oncology team equipped with the resources and experience to manage the complexities and toxicities of re-treatment.

    Ninety five patients of rectal cancer treated with surgery with or without adjuvant radiation therapy since January 1982 to December 1990 at the Chonnam University Hospital were analysed retrospectively regarding local failure. Of these 95 patients 72 patients were treated with surgery alone and remaining 23 patients received postoperative radiation therapy to pelvis. There were 45 men and 50 women with 53 years of median age. Minimum tool low-up period was 19 months and Median was 47 months (range, 19-125 months). Kaplan-Meier method was used to calculate actuarial risk of local recurrence and survival rate. Comparison between two groups was evaluated by Log rank test. Of total 95 patients twenty seven patients (28.4%) developed local recurrence and 13 patients(17.3%) developed local and distant metastasis concomitantly. Eighty nine percent(24/27) of patients developed local recurrence within 24 months. Pelvic organ adjacent to the primary tumor area was the most common site of initial local recurrence. Of 72 patients treated with surgery alone local recurrence developed in 24 patients. Of 17 patients with stage A and B1 (Gunderson-Sosin modification of Dukes staging system) 6 patients experienced local recurrence(31.2%). The local recurrence rate of B2 and B3 group was 29.9%(7/33) and that of C2 and C3 was 54.7%(l1/19), respectively. There was statistically significant difference between two groups(p< 0.05). Of 23 patients treated with definitive surgery and radiation therapy 10%(1/10) recurred in B2 and B3 patients. This was slightly lower than C2 and C3 patients(22.2%, 2/10) of similar policy, but revealed no statistically significant difference(p>0.05). In the patients of B2+3 local failure rate decreased when radiation therapy was added(29.9% vs 10%, p>0.05) and also similar results in C2+3 group(34.7% vs 22.2%, p<0.05). The local failure rate in relation to distance from the anal verge had no statistically significant difference.

    To evaluate the risk factors affecting early diffuse recurrence within 1 year of percutaneous ultrasound-guided radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). Out of 146 patients who received transcatheter arterial chemoembolisation (TACE) for treatment of recurrent HCC after percutaneous ultrasound-guided RFA, we selected 23 patients with early diffuse recurrence. Early diffuse recurrence was defined as three or more new recurrent HCCs within 1 year of initial RFA. As a control group, we selected 23 patients, matched exactly for age and sex, in which there was no local tumour progression or new recurrence after RFA. To analyse the risk factors, we examined patient factors and tumour factors. Recurrent tumours occurred from 30 to 365 days after RFA (median time, 203 days). Univariate analysis indicated that larger tumour size and poorly defined margin were significant risk factors (P < 0.05). Multivariate analysis indicated that poorly defined margin was a significant risk factor (P < 0.05). Larger tumour size and poorly defined margin may be risk factors for early diffuse recurrence of HCC within 1 year of RFA. Tumours with such risk factors should be treated with a combination of TACE to minimise the potential for therapeutic failure. (orig.)

    Most deaths from breast cancer result from tumor recurrence, but the mechanisms underlying tumor relapse are largely unknown. We now report that Par-4 is down-regulated during tumor recurrence and that Par-4 down-regulation is necessary and sufficient to promote recurrence. Tumor cells with low Par-4 expression survive therapy by evading a program of Par-4-dependent multinucleation and apoptosis that is otherwise engaged following treatment. Low Par-4 expression is associated with poor respon...

    The goal of this work was to evaluate the efficacy and toxicity of hyperfractionated stereotactic reirradiation (re-RT) as a treatment for inoperable, recurrent, or second primary head and neck squamous cell cancer (HNSCC) that is not suitable for systemic treatment. Forty patients with recurrent or second primary HNSCC were included in this study. The patients had a median gross tumor volume of 76 ml (range 14-193 ml) and a previous radiotherapy dose greater than 60 Gy. Treatment was designed to cover 95 % of the planning target volume (PTV, defined as gross tumor volume [GTV] + 3 mm to account for microscopic spreading, with no additional set-up margin) with the prescribed dose (48 Gy in 16 fractions b.i.d.). Treatment was administered twice daily with a minimum 6 h gap. Uninvolved lymph nodes were not irradiated. Treatment was completed as planned for all patients (with median duration of 11 days, range 9-14 days). Acute toxicity was evaluated using the RTOG/EORTC scale. A 37 % incidence of grade 3 mucositis was observed, with recovery time of ≤ 4 weeks for all of these patients. Acute skin toxicity was never observed to be higher than grade 2. Late toxicity was also evaluated according to the RTOG/EORTC scale. Mandible radionecrosis was seen in 4 cases (10 %); however, neither carotid blowout syndrome nor other grade 4 late toxicity occurred. One-year overall survival (OS) and local progression-free survival (L-PFS) were found to be 33 and 44 %, respectively. Performance status and GTV proved to be significant prognostic factors regarding local control and survival. Hyperfractionated stereotactic re-RT is a reasonable treatment option for patients with recurrent/second primary HNSCC who were previously exposed to high-dose irradiation and who are not candidates for systemic treatment or hypofractionation.

    ABSTRACT Objective:To study the value of the differentially expressed proteins from primary and recurrent ovarian cancer serum for early diagnosis of primary and recurrent ovarian cancer.Methods:WCX kit(BrukerDaltonicsGraBH) and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS) technology were used to detect serum samples from49 patients with primary ovarian cancer and21 patients with recurrent disease.Results:In the mass range(Mr) from1000 to12000Da, eight differentially expressed protein peaks were screened from primary ovarian cancer serum.Among them, four protein peaks withMr1457,1857,2202, 7761 were lowly expressed and the others withMr2946,5333,5859,5901 were highly expressed. Ten diferentially expressed protein peaks were screened from recurrent ovarian cancer serum. Among them,1944,1980,2080,2661,2993,4450,4659,5359Da protein expressions were increased significantly, and1897,7868Da protein expressions were decreased significantly.The pattern of primary ovarian cancer was applied to8 early-stage ovarian cancer serum samples, and7 serum samples were successfully predicted with the accuracy of87.5%.The pattern of recurrent ovarian cancer was applied to9 without pelvic or abdominal mass recurrent ovarian cancer serum samples, and8 serum samples were successfully predicted with the accuracy of 88.9%.Conclusions:Combination ofMALDI-TOF-MS andWCX kit technology can directly screen the diferrential expressed protein from primary and recurrent ovarian cancer serum.They have clinical significance for enhancement of sensitivity and specificity of ovarian cancer diagnosis.

  2. Salvage cytoreductive surgery for patients with recurrent endometrial cancer: a retrospective study

    International Nuclear Information System (INIS)

    Salvage cytoreductive surgery (SCR) has been shown to improve the survival of cancer patients. This study aimed to determine the survival benefits of SCR for recurrent endometrial cancer in Chinese population. Between January 1995 and May 2012, 75 Chinese patients with recurrent endometrial cancer undergoing SCR were retrospectively analyzed. 43 patients (57.3%) had R0 (no visible disease), 15 patients (20.0%) had R1 (residual disease ≤1 cm), and 17 (22.7%) had R2 (residual disease >1 cm) Resection. 35 patients (46.7%) had single, and 40 (53.3%) had multiple sites of recurrence. The median survival time was 18 months, and 5-year overall survival (OS) rate were 42.0%. Multivariate analysis showed that residual disease ≤1 cm and high histology grade were significantly associated with a better OS. The size of the largest recurrent tumors (≤6 cm), solitary recurrent tumor, and age at recurrence (≤56 years old) were associated with optimal SCR. Optimal SCR and high histology grade are associated with prolonged overall survival for patients with recurrent endometrial cancer. Patients with young age, tumor size < 6 cm, and solitary recurrent tumor are more likely to benefit from optimal cytoreductive surgery

  4. Treatment of locally advanced/locally recurrent breast cancer and inflammatory breast cancer

    Murakami, Masao [Tenri Hospital, Nara (Japan)

    2000-10-01

    This paper summarizes the treatment of locally advanced breast cancer, inflammatory breast cancer, and locally recurrent breast cancer. A multidisciplinary approach considering subclinical distant metastases is needed to treat these types of breast cancer. Subclinical distant metastasis is observed in about 80% of case of locally advanced cancer, and treatment of subclinical distant metastases, e.g., by endocrinotherapy and chemotherapy, is therefore essential to improving the prognosis. The standard therapy for unresectable locally advanced breast cancer consists of induction chemotherapy with anthracyclines and local treatment with mastectomy or irradiation. Previous reports have stated that induction chemotherapy was effective in 60-80% of the primary lesions or lymph node metastasis, and the CR rates were in the 10-20% range. Combination therapy with induction chemotherapy clearly improved the outcome over local treatment alone. The usual irradiation dose is 50 to 60 Gy/5 to 7 weeks to the whole breast or the thoracic wall. Boost irradiation at a dose of 10 to 25 Gy is performed in unresectable cases. The boost irradiation dose to the lymph node area is usually 45 to 50 Gy/5 to 6 weeks in cases without gross lesions and 10 to 15 Gy in cases with gross lesions. Combination therapy consisting of conservative pectoral mastectomy and postoperative adjuvant chemo- endocrino-therapy (i.e., adjuvant therapy) has become the standard regimen for treating resectable locally advanced breast cancer, because it significantly improves the recurrence rate and survival rate compared to local treatment alone. Some clinical have studies indicated that neoadjuvant therapy (i.e., induction chemotherapy + surgery/radiation therapy) is comparable or superior to adjuvant therapy in terms of improving the prognosis. However, the efficacy and most appropriate method of breast-conserving therapy after induction chemotherapy are still unclear. More clinical trials are needed. It has been

    Full Text Available PURPOSE: Socioeconomic status (SES may influence cancer characteristics and behavior in several aspects. We analyzed PCa characteristics and behavior among low income uninsured men, and compare them to high income patients with health insurance in a developing country. MATERIALS AND METHODS: A retrospective case-control study was performed on 934 patients with clinically localized PCa who underwent radical prostatectomy between March, 1999 and July, 2009. Patients were divided in two groups, according to their SES. In group 1 (n=380, all had low income, low educational levels and couldn't afford medical insurance. In group 2 (n=554, all had higher income, higher education and had medical insurance. RESULTS: Patients from group 1 were older, had higher Gleason scores, higher rates of seminal vesicle and bladder neck involvement. The Kaplan Meier disease-free survival curve demonstrated that after a follow-up of four years, about 50% of uninsured patients had biochemical recurrence, versus 21% of insured patients (Log rank test: p < 0.001. A multivariate Cox regression analysis for the risk of disease recurrence demonstrated that only PSA levels, Gleason score, seminal vesicle involvement and SES were statistically significant variables. Patients with a low SES presented 1.8 times the risk of recurrence as compared to patients with a high SES. CONCLUSIONS: Patients with low SES were older, presented more aggressive PCa characteristics and a high rate of disease recurrence. A low SES constituted an independent predictor for disease recurrence.

  10. Obesity and colorectal cancer risk

    International Nuclear Information System (INIS)

    Obesity is a chronic and multifactor disease characterized by presence of excess body fat harmful for health. Several studies have been conducted to assess the possible risk character of different factors for colorectal cancer including the following modifying factors: a diet rich in saturated fats, a diet low in vegetables, physical inactivity, alcohol consumption and obesity. A case-control study was conducted to include 276 adult patients (93 cases and 184 controls) consecutively seen from May, 2008 to May, 2009 in the Institute of Gastroenterology determining a possible association between obesity as risk factor and colorectal cancer. Variables measures included: sex, age, skin color, body mass index, hip-waist circumference and endoscopic location of cancer. We conclude that the colorectal cancer with predominance in female sex and in white people in both groups. Obesity according to a great relation hip-waist had an strong relation with colorectal cancer, which had predominance towards distal colon in both sexes

    Full Text Available Purpose. The recurrence of CBD stone is still observed in a considerable number of patients. The study was to evaluate the risk factors for recurrence of symptomatic CBD stone in patients who underwent cholecystectomy after the removal of CBD stone. Methods. The medical records of patients who underwent removal of CBD stone with subsequent cholecystectomy were reviewed. The risk factors for the recurrence of symptomatic CBD stone were compared between the recurrence and the nonrecurrence group. Results. The mean follow-up period was 40.6 months. The recurrence of symptomatic CBD stones was defined as the detection of bile duct stones no sooner than 6 months after complete clearance of CBD stones, based on symptoms or signs of biliary complication. 144 patients (68 males, 47.2% were finally enrolled and their mean age was 59.8 (range: 26~86 years. The recurrence of CBD stone occurred in 15 patients (10.4%. The mean period until first recurrence was 25.9 months. The presence of type 1 or 2 periampullary diverticulum and multiple CBD stones were the independent risk factors. Conclusion. For the patients with type 1 or 2 periampullary diverticulum or multiple CBD stones, careful followup is needed for the risk in recurrence of symptomatic CBD stone.

  12. Risk Factors for Fatal Recurrence of Liver Transplant Recipients with Hepatocellular Carcinoma in the First Year

    2007-01-01

    Objective: To investigate the clinicopathological risk factors for fatal recurrence of hepatocellular carcinoma (HCC) in orthotopic liver transplant recipients in the first year. Methods: From April 2002 to October 2005, 303 recipients who received orthotopic liver transplantation for HCC were reviewed. Of These patients, those who demonstrated diffuse intra-hepatic or multiple systemic recurrent lesions and died within 1 y after surgery were investigated (fatal recurrence group, 48 cases). The remaining patients were designated as the control group, and the two groups were compared for clinicopathologic risk factors by logistic regression analysis. Results: Among the 303 patients reviewed, 48 patients were enrolled in the fatal recurrence group (15.84%). Multivariate analysis between the fatal recurrence group and control group showed that the presence of vascular invasion, tumor size greater than 6.5 cm, and pre-operative serum alpha-fetoprotein (AFP) level greater than 1000 μg/L were the risk factors in the fatal recurrence group. 85.71% of the patients who had all the three risk factors, 37.84% of those who had two risk factors, 13.64% of those who had one risk factors, and 6.71% of those who had none risk factors died because of recurrence within 1 y after transplantation. Conclusion: Three distinct risk factors attributed to fatal recurrence of liver transplant recipients for HCC are vascular invasion, tumor size ≥6.5 cm, and pre-operative serum AFP level ≥1000 μg/L. The high risk HCC patients with two or more risk factors should not to be the candidates for liver transplantation.

    Aim: to investigate the use of minimally invasive high-intensity focused ultrasound (HIFU) as a salvage therapy in men with localized prostate cancer recurrence following external beam radiotherapy (EBRT), brachytherapy or proton therapy. A review of 22 cases treated using the Sonablate® 500 HIFU device, between August 28, 2002 and April 1, 2010, was carried out. All men had presumed organ-confined, histologically confirmed recurrent prostate adenocarcinoma following radiation therapy. The mean (range) age was 65 (52-80) years with a mean PSA level before radiation therapy of 14.3 (5.7-118) ng/mL. The mean (range) period after radiation therapy to HIFU was 36 (4-96) months. All men with presumed, organ-confined, recurrent disease following EBRT in 14 patients, brachytherapy in 5 patients (4 patients with high-dose brachytherapy with In192 and 1 with low-dose brachytherapy with Au98) or proton therapy in 3 patients treated with salvage HIFU were included. The patients were followed for a mean (range) of 24 months. Biochemical disease-free survival (bDFS) rates in patients with low-, intermediate-and high risk groups were 100%, 86%, and 14%, respectively. All nine patients who received a post HIFU prostate biopsy showed no malignancy. Side-effects included urethral stricture in 4 of the 25 patients (16%) and urinary incontinence in 4 of the 25 patients (16%). Recto-urethral fistula occurred in one patient (4%). Salvage HIFU is a minimally invasive for patients with low-and intermediate risk group with comparable morbidity to other forms of salvage treatment.

Classification of COPD severity was based on guidelines of the Global Initiative for Chronic Obstructive Lung Disease (GOLD. Characteristics among the three subgroups were compared and recurrence-free survivals were analyzed.Results: A total of 172 patients were diagnosed with COPD (124 as GOLD-1, 46 as GOLD-2, and two as GOLD-3. The frequencies of recurrence were significantly higher in patients with higher COPD grades (P<0.001. Recurrence-free survival at 5 years was 78.1%, 70.4%, and 46.4% in non-COPD, mild COPD, and moderate/severe COPD groups, respectively (P<0.001. By univariate analysis, the age, sex, smoking history, COPD severity, tumor size, histology, and pathological stage were associated with recurrence-free survival. Multivariate analysis showed that older age, male, moderate/severe COPD, and advanced stage were independent risk factors associated with recurrence-free survival.Conclusion: NSCLC patients with COPD are at high risk for postoperative recurrence, and moderate/severe COPD is an independent unfavorable prognostic factor.

    We report two cases of solitary mediastinal lymph node recurrence after colon cancer resection. Both cases had para-aortic lymph node metastasis at the time of initial surgery and received adjuvant chemotherapy for 4 years in case 1 and 18 mo in case 2. The time to recurrence was more than 8 years in both cases. After resection of the recurrent tumor, the patient is doing well with no recurrence for 6 years in case 1 and 4 mo in case 2. Patients should be followed up after colon cancer surgery considering the possibility of solitary mediastinal lymph node recurrence if they had para-aortic node metastasis at the time of initial surgery.

    We report a case of a 59-year-old woman who was forced to undergo mastectomy of the right breast (Rt Bt) plus axillary lymph node (Ax) dissection for right breast cancer at another hospital. The pathological diagnosis was invasive ductal carcinoma( scirrhou[s sci], pT2N2M0, Stage IIIA, estrogen recepto[r ER[]+], progesterone recepto[r PgR[]+], human epidermal growth factor receptor-2[HER2][2+]). Although no recurrence was observed after postoperative adjuvant chemotherapy and endocrine therapy, skin metastasis on the left back and pleuritis carcinomatosa were detected at our hospital 9 years and 6 months after the operation. Thereafter, bone metastasis, contralateral lymph node metastasis, and frequent occurrence of hepatic metastasis were sequentially detected. The patient was treated with chemotherapy (a total of 4 regimens) and endocrine therapy in addition to radiation therapy for lymph node metastasis over a period of approximately 2 years and 3 months; however, disease control was poor. Therefore, combined chemotherapy with paclitaxel and bevacizumab was initiated from February 2012. Soon after the initiation of combination therapy, the serum carcinoembryonic antigen (CEA) level gradually reduced and computed tomography (CT) revealed that the multiple-organ metastases had remarkably reduced in size. The response was classified as a clinical partial response (cPR). Although adverse events such as peripheral neuropathy, nose bleeding, and high blood pressure were observed, these were all of lesser that Grade 2 severity. The efficacy of chemotherapy was noted for 11 months. PMID:24394122

    To minimize the recurrence of a previously treated neoplasm in organ recipients, a period of 2 to 5 years without recurrence is advocated for most malignancies. However, prostate cancer is different because of its biological properties, diagnosis, and treatment. Most prostate cancers are detected at a low stage and demonstrate slow growth after detection. Definitive treatment with radical prostatectomy affords excellent results. Renal transplant candidates with early-stage prostate cancer have a higher risk of dying on dialysis than dying from prostate cancer; therefore, renal transplant candidates with organ-confined prostate cancer should be immediately considered for transplant.

    2010-01-01

    This report reviews current evidence regarding the relationship between vegetarian eating patterns and cancer risk. Although plant-based diets including vegetarian and vegan diets are generally considered to be cancer protective, very few studies have directly addressed this question. Most large prospective observational studies show that vegetarian diets are at least modestly cancer protective (10%-12% reduction in overall cancer risk) although results for specific cancers are less clear. No long-term randomized clinical trials have been conducted to address this relationship. However, a broad body of evidence links specific plant foods such as fruits and vegetables, plant constituents such as fiber, antioxidants and other phytochemicals, and achieving and maintaining a healthy weight to reduced risk of cancer diagnosis and recurrence. Also, research links the consumption of meat, especially red and processed meats, to increased risk of several types of cancer. Vegetarian and vegan diets increase beneficial plant foods and plant constituents, eliminate the intake of red and processed meat, and aid in achieving and maintaining a healthy weight. The direct and indirect evidence taken together suggests that vegetarian diets are a useful strategy for reducing risk of cancer. PMID:21407994

    Aim: To evaluate patterns of disease and identify factors predicting outcome in patients presenting with recurrent endometrial adenocarcinoma following primary surgery. Materials and methods: A retrospective review was performed of the imaging and clinical data in 86 patients (median age 66 years, range 42-88 years) presenting with recurrent endometrial adenocarcinoma following primary surgery. Results: Following primary surgery recurrent disease occurred within 2 years in 64% and within 3 years in 87%. Relapse was seen within lymph nodes in 41 (46%), the vagina in 36 (42%) the peritoneum in 24 (28%) and the lung in 21 (24%). Unusual sites of disease included spleen, pancreas, rectum, muscle and brain. Univariate survival analysis showed the factors significant for poor outcome were: multiple sites of disease, liver and splenic disease, haematogenous, peritoneal and nodal spread, poorly differentiated tumour, and early relapse. The presence of disease within the vagina, bladder or lung was not associated with poor prognosis. Multivariate analysis identified multiple sites of disease, liver and splenic metastases to be independent predictors of poor outcome. Conclusion: The most frequently observed sites of relapse are: lymph nodes, vagina, peritoneum and lung. Significant predictors of poor outcome in recurrent disease are multiple sites of disease and liver and splenic metastases.

    Full Text Available Pancreatic cancer represents one of the leading causes of cancer related deaths worldwide and constitutes a major public health problem. Despite the advances in diagnosis and treatment, the overall five-year survival remains low, thus leading the focus of medical research towards the identification and modification of potential risk factors. This year, in ASCO Annual Meeting two interesting studies were presented. Ghani et al. (abstract #e15183 sought to investigate the effect of smoking on chemotherapy response in patients with metastatic pancreatic cancer, while Walker et al. (abstract #4117 presented the results of their study regarding the effect of statin use in the prevention of pancreatic cancer. Both studies concluded to useful results that along with the existing literature may further stimulate medical research towards better recognition of risk factors and the application of this knowledge in the clinical practice.

    Huang, Haibo; Ji, Hua; Tian, Hui

    2015-06-01

    Primary spontaneous pneumothorax recurs at a certain rate after thoracoscopic surgery, and risk factors for that recurrence are in question. The medical records of 248 patients with primary spontaneous pneumothorax who were followed for more than 2 years after thoracoscopic surgery were reviewed and retrospectively analyzed. Univariate and multivariate binary logistic regression analysis were used to identify possible risk factors. Twelve patients experienced the recurrence of primary spontaneous pneumothorax. Patients who experienced the recurrence of primary spontaneous pneumothorax were younger than patients who experienced no recurrence. A larger proportion of the patients who experienced recurrence did not undergo pleurodesis. The variables age, height, weight, body mass index, duration of air leakage, and pleurodesis (performed or not) with a p value less than 0.2 in univariate analysis were entered in multivariate analysis. A younger age and not undergoing pleurodesis were associated with a higher risk of postoperative ipsilateral recurrence of primary spontaneous pneumothorax. Not undergoing pleurodesis and a younger age are possible risk factors for recurrence of primary spontaneous pneumothorax after thoracoscopic surgery. Thoracic surgeons should pay more attention to pleurodesis, especially in younger patients.

  11. Risk Stratification in Differentiated Thyroid Cancer: An Ongoing Process.

    2016-01-28

    Thyroid cancer is an increasingly common malignancy, with a rapidly rising prevalence worldwide. The social and economic ramifications of the increase in thyroid cancer are multiple. Though mortality from thyroid cancer is low, and most patients will do well, the risk of recurrence is not insignificant, up to 30%. Therefore, it is important to accurately identify those patients who are more or less likely to be burdened by their disease over years and tailor their treatment plan accordingly. The goal of risk stratification is to do just that. The risk stratification process generally starts postoperatively with histopathologic staging, based on the AJCC/UICC staging system as well as others designed to predict mortality. These do not, however, accurately assess the risk of recurrence/persistence. Patients initially considered to be at high risk may ultimately do very well yet be burdened by frequent unnecessary monitoring. Conversely, patients initially thought to be low risk, may not respond to their initial treatment as expected and, if left unmonitored, may have higher morbidity. The concept of risk-adaptive management has been adopted, with an understanding that risk stratification for differentiated thyroid cancer is dynamic and ongoing. A multitude of variables not included in AJCC/UICC staging are used initially to classify patients as low, intermediate, or high risk for recurrence. Over the course of time, a response-to-therapy variable is incorporated, and patients essentially undergo continuous risk stratification. Additional tools such as biochemical markers, genetic mutations, and molecular markers have been added to this complex risk stratification process such that this is essentially a continuum of risk. In recent years, additional considerations have been discussed with a suggestion of pre-operative risk stratification based on certain clinical and/or biologic characteristics.

Materials and Methods In the period from January 1998 to August 2007, 120 patients were treated with iodine-125 brachytherapy alone. The results analysis was based on the definition of biochemical recurrence according to the Phoenix Consensus. Results Biochemical control was observed in 86 patients (71.7%, and biochemical recurrence, in 34 (28.3%. Mean PSAn was 0.53 ng/ml. The mean follow-up was 98 months. The patients were divided into two groups: group 1, with two year PSAn < 0.5 ng/ml after brachytherapy (74 patients; 61.7%, and group 2, with two year PSAn ≥ 0.5 ng/ml after brachytherapy (46 patients; 38.3%. Group 1 presented biochemical recurrence in 15 patients (20.3%, and group 2, in 19 patients (43.2% (p < 0.02. The analysis of biochemical disease-free survival at seven years, stratified by the two groups, showed values of 80% and 64% (p < 0.02, respectively. Conclusion Levels of two year PSAn ≥ 0.5 ng/ml after brachytherapy are strongly correlated with a poor prognosis. This fact may help to identify patients at risk for disease recurrence.

    Cancer recurrence is believed to be one of the major reasons for the failure of cancer treatment strategies. Thisbiological phenomenon could arise from the incomplete eradication of tumour cells after chemo- and radiotherapy.Recent developments in the design of models reflecting cancer recurrence and in vivo imaging techniques have ledresearchers to gain a deeper and more detailed insight into the mechanisms underlying tumour relapse. Here, weprovide an overview of three important drivers of recurrence including cancer stem cells (CSCs), neosis, and phoenixrising. The survival of cancer stem cells is well recognized as one of the primary causes of therapeutic resistance inmalignant cells. CSCs have a relatively latent metabolism and show resistance to therapeutic agents through a varietyof routes. Neosis has proven to be as an important mechanism behind tumour self-proliferation after treatment whichgives rise to the expansion of tumour cells in the injured site via production of Raju cells. Phoenix rising is a prorecurrencepathway through which apoptotic cancer cells send strong signals to the neighbouring diseased cellsleading to their multiplication. The mechanisms involved in therapeutic resistance and tumour recurrence have not yetbeen fully understood and mostly remain unexplained. Without doubt, an improved understanding of the cellularmachinery contributing to recurrence will pave the way for the development of novel, sophisticated and effective antitumourtherapeutic strategies which can eradicate tumour without the threat of relapse.

    Background Dysregulation of apoptosis has been implicated not only in carcinogenesis and tumor progression but also in tumor recurrence. We investigated whether the expression of X-linked inhibitor of apoptosis (XIAP) might predict early recurrence in patients with non-muscular invasive bladder cancer.Methods The cohort comprised 176 consecutive patients with primary superficial bladder cancer treated with transurethral resection. Immunohistochemical staining using the standard avidin-biotin-peroxidase technique and RT-PCR were used to detect XIAP protein and mRNA expressions in cancer tissues. The relationship between XIAP expression and clinicopathological characteristics, cancer recurrence were analyzed.Results XIAP expression was observed in 108 cases (61.4%) and no expression in 68. There was no correlation between XIAP expression rate and the tumor pathological grade, but was an apparent trend toward the increased XIAP levels from well (G1) to poor (G3) differentiated cancer. Eighty-two (46.6%) patients experienced tumor recurrence at a mean of 28.6 months of the follow-up; 66 of them expressed XIAP (61.1%) and 16 were XIAP negative (23.5%). Twelve patients presented with invasive disease at the time of relapse and all of them expressed XIAP. Patients without XIAP expression or with low tumor grades had significantly higher recurrence-free survival than those with XIAP expression(log rank test P=0.0015) or high tumor grades (log rank test P<0.001). Multivariate analysis revealed that XIAP expression, tumor grade, and tumor number were independent predictors for the recurrence of non-muscular invasive bladder cancer (P=-0.004, 0.016, and 0.043, respectively).Conclusions XIAP may be considered as a new independent prognostic marker for early recurrence of non-muscular invasive bladder cancer.

    Background Studies have shown that irinotecan can improve survival in patients with advanced or recurrent gastric cancer,but the overall benefit of irinotecan in the treatment of advanced or recurrent gastric cancer remains controversial.The aim of this study was to evaluate the benefits and risks of irinotecan for survival in patients with advanced or recurrent gastric cancer.Method We searched PubMed,EmBase,the Cochrane Central Register of Controlled Trials,reference lists of articles,and proceedings of major conferences for relevant clinical trials.We included randomized controlled trials that reported on the efficacy and safety of irinotecan in patients with advanced or recurrent gastric cancer.Outcomes were analyzed by survival rate,objective response rate (ORR),and toxicity.Furthermore,the analysis was further stratified by factors that could affect the treatment effects.Results Eight trials recruiting 1 546 patients with advanced or recurrent gastric cancer were included in the analysis.Overall,irinotecan therapy was associated with a 6% improvement in survival rate,but this difference was not statistically significant (odds ratio (OR) 0.94; 95% confidence interval (95% CI) 0.70-1.27; P=-0.69).However,irinotecan therapy had more frequent ORR than irinotecan-free arm (OR 1.70; 95% CI 1.34-2.17; P <0.001).Furthermore,irinotecan therapy was associated with a clinically and statistically significant increase in the risk for declined hemoglobin,hyponatremia,and diarrhea,but it also protected against thrombocytopenia risk when compared with irinotecan-free therapy.Conclusions There is no evidence to support the use of irinotecan therapy in patients with advanced or recurrent gastric cancer; however,given the significant advantage in ORR irinotecan therapy using combination regimens may be considered for further evaluation in subsets of patients who may benefit from this treatment.

    Full Text Available To estimate the risks of and identify predictors for recurrent subdural haematoma in surgically and conservatively treated patients.The cohort comprised all individuals diagnosed with a first-time subdural hematoma in Denmark 1996-2011. Information on potential predictors was retrieved from the Danish health registers. Cumulative recurrence risks were estimated using the Aalen-Johansen estimator. Rate ratios (RR were estimated using Poisson regression.Among 10,158 individuals with a subdural hematoma, 1,555 had a recurrent event. The cumulative risk of recurrent subdural hematoma was 9% at 4 weeks after the primary bleeding, increasing to and stabilising at 14% after one year. Predictors associated with recurrence were: Male sex (RR 1.60, 95% CI:1.43-1.80, older age (>70 years compared to 20-49 years; RR 1.41, 95% CI: 1.21-1.65, alcohol addiction (RR 1.20, 95% CI:1.04-1.37, surgical treatment (RR 1.76, 95% CI:1.58-1.96, trauma diagnoses (RR 1.14, 95% CI:1.03-1.27, and diabetes mellitus (RR 1.40, 95% CI:1.11-1.74. Out of a selected combination of risk factors, the highest cumulative 1-year recurrence risks for subdural hematoma of 25% (compared to 14% for all patients was found in surgically treated males with diabetes mellitus.The recurrence risk of subdural hematoma is largely limited to the first year. Patient characteristics including co-morbidities greatly influence the recurrence risk of SDH, suggesting that individualized prognostic guidance and follow-up is needed.

  20. Local recurrences and distant metastases after breast-conservative treatments in a population at very low risk of recurrence are very dependent events

    International Nuclear Information System (INIS)

    PURPOSE: Assessment of the relative merits of individual factors influencing the risks of loco-regional failure (LRF) and metastases (M) after breast-preserving treatments is made difficult by the marked inhomogeneities within the published series: short follow-up, use of chemotherapy, nodal status, margins of resection. We therefore selected a very homogenous population with an expected low-risk of recurrence to identify high-risk subgroups which may need more aggressive treatments. MATERIALS AND METHODS: Between 1980 and 1995, 3697 women with breast cancer were referred to Paoli-Calmettes Cancer Center, Marseille. Patients included in the study had undergone axillary dissection and were node negative (n=1840), were treated with conservative surgery (usually lumpectomy) and standard radiotherapy (n=1241), had histological tumor sizes ≤ 50 mm, received no chemotherapy (n=1024), and had negative margins of resection (n=756). Hormonal therapy was given to 238 women (31.5%): castration for premenopausal women (n=92), tamoxifen for postmenopausal women (n=146). The following factors were entered in the univariate analysis: age (≤ 40 yrs. vs > 40 yrs.), menopausal status, hormonal treatment, peritumoral vessel invasion (PVI), histologic multifocality (HM), extensive intraductal component (EIC), estrogen receptor (ER) and progesterone receptor (PR) status, SBR grade (I vs II vs III) and histological size (≤20 mm vs >20 mm). Factors statistically significant (p+ and 72.1% PR+ tumors. PVI was found in 184 tumors and EIC only in 30 tumors whereas HM was found in 106 cases. There were 53 local recurrences, 8 locoregional failures and 65 metastases as first event. The yearly conditional event probability for LRF and M was 1.8% and 1.6% respectively, constant over the years. Five and ten-year freedom from recurrence rates were 92.7% [90.4%-94.9%] and 81.6% [76.2%-86.9%] respectively for LRFs, and 91.6% [89.2%-94%] and 83.6% [79%-88.1%] respectively for M. Patients with

    Full Text Available Abstract Background In Belgium, bladder cancer is the fifth most common cancer in males (5.2% and the sixth most frequent cause of death from cancer in males (3.8%. Previous epidemiological studies have consistently reported that selenium concentrations were inversely associated with the risk of bladder cancer. This suggests that selenium may also be suitable for chemoprevention of recurrence. Method The SELEBLAT study opened in September 2009 and is still recruiting all patients with non-invasive transitional cell carcinoma of the bladder on TURB operation in 15 Belgian hospitals. Recruitment progress can be monitored live at http://www.seleblat.org. Patients are randomly assigned to selenium yeast (200 μg/day supplementation for 3 years or matching placebo, in addition to standard care. The objective is to determine the effect of selenium on the recurrence of bladder cancer. Randomization is stratified by treatment centre. A computerized algorithm randomly assigns the patients to a treatment arm. All study personnel and participants are blinded to treatment assignment for the duration of the study. Design The SELEnium and BLAdder cancer Trial (SELEBLAT is a phase III randomized, placebo-controlled, academic, double-blind superior trial. Discussion This is the first report on a selenium randomized trial in bladder cancer patients. Trial registration ClinicalTrials.gov identifier: NCT00729287

    Objective Obesity is an established risk factor for colorectal cancer (CRC) incidence and it is also linked to CRC recurrence and survival. Polymorphisms located in obesity-related genes are associated with increased risk of developing several cancer types including colorectal cancer. We evaluated whether SNPs in obesity-related genes may predict tumor recurrence in colon cancer patients. Methods Genotypes were obtained from germline DNA from 207 patients with stage II or III colon cancer at the Norris Comprehensive Cancer Center. Nine polymorphisms in eight obesity-related genes (PPAR, LEP, NFKB, CD36, DRG1, NGAL, REGIA and DSCR1) were evaluated. The primary endpoint of the study was 3-year recurrence rate. Positive associations were also tested in an independent Japanese cohort of 350 stage III CRC patients. Results In univariate analysis, for PPAR rs1801282, patients with a CC genotype had significantly lower recurrence probability (29± 4% standard error, SE) compared to patients with a CG genotype (48% ± 8% SE), HR: 1.77; 95%CI, 1.01-3.10; p=0.040. For DSCR1 rs6517239, patients with an AA genotype had higher recurrence probability than patients carrying at least one allele G (37% ± 4% SE vs 15% ± 6% SE), HR: 0.51, 95% CI, 0.27-0.94; p=0.027. This association was stronger in the patients bearing a left-sided tumor (HR: 0.34; 95%CI, 0.13-0.88; p=0.018). In the Japanese cohort no associations were found. Conclusion This hypothesis generating study suggests a potential influence of polymorphisms within obesity-related genes in the recurrence probability of colon cancer. These interesting results should be further evaluated. PMID:25379721

    2005-01-01

    We report a case of a 77-year-old female with a local recurrence of cancer after right hemicolectomy which infiltrated the pancreatic head affording pancreatoduodenectomy, who developed 3 years later recurrent tumor masses localized in the mesentery of the jejunum and in the lower pole of the left kidney. Partial nephrectomy and a segment resection of the small bowel were performed. Histological examination of both specimens revealed a necrotic metastasis of the primary carcinoma of the colon. Although intraluminal implantation of colon cancer cells in the renal pelvic mucosa from ureteric metastasis has been described, metastasis of a colorectal cancer in the kidney parenchyma is extremely rare and can be treated in an organ preserving manner. A complex pattern of colon cancer recurrence with unusual and rare sites of metastasis is reported.

    Many cancers have been linked to copy number variations (CNVs) in the genomic DNA. Although there are existing methods to analyze CNVs from individual samples, cancer-causing genes are more frequently discovered in regions where CNVs are common among tumor samples, also known as recurrent CNVs. Integrating multiple samples and locating recurrent CNV regions remain a challenge, both computationally and conceptually. We propose a new graph-based algorithm for identifying recurrent CNVs using the maximal clique detection technique. The algorithm has an optimal solution, which means all maximal cliques can be identified, and guarantees that the identified CNV regions are the most frequent and that the minimal regions have been delineated among tumor samples. The algorithm has successfully been applied to analyze a large cohort of breast cancer samples and identified some breast cancer-associated genes and pathways.

    Objective: To explore the affecting factors of liver cancer recurrence after hepatectomy. Methods:The BP artificial neural network - Cox regression was introduced to analyze the factors of recurrence in1 457 patients. Results: The affecting factors statistically significant to liver cancer prognosis was selected.There were 18 factors to be selected by uni-factor analysis, and 9 factors to be selected by multi-factor analysis. Conclusion: The 9 factors selected can be used as important indexes to evaluate the recurrence of liver cancer after hepatectomy. The artificial neural network is a better method to analyze the clinical data, which provides scientific and objective data for evaluating prognosis of liver cancer.

  8. Loco-regional recurrences after mastectomy in breast cancer: prognostic factors and implications for postoperative irradiation

    International Nuclear Information System (INIS)

    Purpose: Potential risk factors including DNA flow cytometric-derived parameters predicting loco-regional recurrence (LRR) in early breast cancer were investigated.Materials and methods: This study included 608 patients treated by modified radical mastectomy between 1982 and 1987. Recommendations regarding local treatment as well as adjuvant systemic therapy did not change during this period. Patients treated by adjuvant chemotherapy were randomized to receive additional medroxyprogesterone acetate (MPA) treatment. Only 59 (10%) patients received postoperative irradiation (XRT) to the chest wall and/or axillary lymph nodes; another 121 (20%) patients received XRT to the internal mammary nodes because of centromedially located tumours.Results: Patients were followed for a median period of 7.5 years. The event-free survival at 10 years was 50%. The cumulative incidence rate of LRR at 10 years was 18% (n=93), either with (n=30) or without (n=63) concurrent distant metastases. The chest wall, regional lymph nodes or both were involved in 41 (44%), 38 (41%) and 12 (13%) patients, respectively. Multivariate analysis according to the Cox model revealed two factors associated with LRR, i.e. pT (P<0.05) and nodal status (P<0.0510%) and low risk (<10%) group for LRR could be identified.Conclusions: Results indicate that T-stage and nodal status, combined with ECE, may help to identify patients at risk for loco-regional recurrence, whereas DNA flow cytometry does not.

    AIM: To investigate predilection sites of recurrence of pancreatic cancer by computed tomography (CT) in follow-up after surgery. METHODS: Seventy seven patients with recurrence after pancreatic cancer surgery were retrospectively identified. The operative technique, R-status, T-stage and development of tumor markers were evaluated. Two radiologists analyzed CT scans with consensus readings. Location of local recurrence, lymph node recurrence and organ metastases were noted. Surgery and progression of findings on follow-up CT were conRESULTS: The mean follow-up interval was 3.9 ± 1.8 mo, with a mean relapse-free interval of 12.9 ± 10.4 mo. The predominant site of recurrence was local (65%), followed by lymph node (17%), liver metastasis (11%) and peritoneal carcinosis (7%). Local recurrence emerged at the superior mesenteric artery (n = 28), the hepatic artery (n = 8), in an area defined by the surrounding vessels: celiac trunk, portal vein, inferior vena cava (n = 22), and in a space limited by the mesenteric artery, portal vein and inferior vena cava (n = 17). Lymph node recurrence occurred in the mesenteric root and left lateral to the aorta. Recurrence was confirmed by surgery (n = 22) and follow-up CT (n = 55). Tumor markers [carbohydrate antigen 19-9 (CA19-9), carcinoembryonic antigen (CEA)] increased in accordance with signs of recurrence in most cases (86% CA19-9; 79.2% CEA). CONCLUSION: Specific changes of local and lymph node recurrence can be found in the course of the cardinal peripancreatic vessels. The superior mesenteric artery is the leading structure for recurrence.

    Purpose: Rational design of targeted radiotherapy (RT) in prostate cancer (Pca) hinges on a better understanding of spatial patterns of recurrence. We sought to identify pathological factors predictive for site of local recurrence (LR) after external beam RT. Methods and Materials: Prospective databases were reviewed to identify men with LR after RT from 1997 through 2009. Patients with biochemical failure and biopsy-confirmed Pca more than 2 years after RT were evaluated. Prediction for site of recurrence based on the following pretreatment factors was determined on independent and cluster-sextant basis: presence of malignancy, dominant vs. nondominant percentage core length (PCL) involvement, PCL {>=} or <40%, and Gleason score. Sites of dominant PCL were defined as sextants with peak PCL involvement minus 10%, and >5% for each patient. Results: Forty-one patients with low-intermediate risk Pca constituted the study cohort. Median time to biopsy after RT was 51 months (range, 24-145). Of 246 sextants, 74 were involved with tumor at baseline. When sextants are treated as independent observations the presence of malignancy (77% vs. 22%, p = 0.0001), dominant PCL (90% vs. 46%, p = 0.0001), and PCL {>=}40% (89% vs. 68 %, p = 0.04) were found to be significant predictors for LR, although PCL {>=}40% did not retain statistical significance if sextants were considered correlated. The vast majority of patients (95%) recurred at the original site of dominant PCL or PCL {>=}40%, and 44% also recurred in regions of nondominant PCL <40% (n = 8) and/or benign sampling (n = 14) at baseline. Conclusions: LR after RT predominantly occurs in regions bearing higher histological tumor burden but are not isolated to these sites. Our data highlights the value of spatially resolved baseline pathological sampling and may assist in the design of clinical trials tailoring RT dose prescriptions to subregions of the prostate gland.

    Ryosuke Tateishi

    Full Text Available BACKGROUND: In the treatment of hepatocellular carcinoma (HCC, hepatic resection has the advantage over radiofrequency ablation (RFA in terms of systematic removal of a hepatic segment. METHODS: We enrolled 303 consecutive patients of a single naïve HCC that had been treated by RFA at The University of Tokyo Hospital from 1999 to 2004. Recurrence was categorized as either intra- or extra-subsegmental as according to the Couinaud's segment of the original nodule. To assess the relationship between the subsegments of the original and recurrent nodules, we calculated the kappa coefficient. We assessed the risk factors for intra- and extra-subsegmental recurrence independently using univariate and multivariate Cox proportional hazard regression. We also assessed the impact of the mode of recurrence on the survival outcome. RESULTS: During the follow-up period, 201 patients in our cohort showed tumor recurrence distributed in a total of 340 subsegments. Recurrence was categorized as exclusively intra-subsegmental, exclusively extra-subsegmental, and simultaneously intra- and extra-subsegmental in 40 (20%, 110 (55%, and 51 (25% patients, respectively. The kappa coefficient was measured at 0.135 (95% CI, 0.079-0.190; P<0.001. Multivariate analysis revealed that of the tumor size, AFP value and platelet count were all risk factors for both intra- and extra-subsegmental recurrence. Of the patients in whom recurrent HCC was found to be exclusively intra-subsegmental, extra-subsegmental, and simultaneously intra- and extra-subsegmental, 37 (92.5%, 99 (90.8% and 42 (82.3%, respectively, were treated using RFA. The survival outcomes after recurrence were similar between patients with an exclusively intra- or extra-subsegmental recurrence. CONCLUSIONS: The effectiveness of systematic subsegmentectomy may be limited in the patients with both HCC and chronic liver disease who frequently undergo multi-focal tumor recurrence.

    To explore novel genetic abnormalities occurring in myelodysplastic syndromes (MDS) through an integrative study combining array-based comparative genomic hybridization (aCGH) and next-generation sequencing (NGS) in a series of MDS and MDS/myeloproliferative neoplasms (MPN) patients. 301 patients diagnosed with MDS (n = 240) or MDS/MPN (n = 61) were studied at the time of diagnosis. A genome-wide analysis of DNA copy number abnormalities was performed. In addition, a mutational analysis of DNMT3A, TET2, RUNX1, TP53 and BCOR genes was performed by NGS in selected cases. 285 abnormalities were identified in 71 patients (23.6%). Three high-risk MDS cases (1.2%) displayed chromothripsis involving exclusively chromosome 13 and affecting some cancer genes: FLT3, BRCA2 and RB1. All three cases carried TP53 mutations as revealed by NGS. Moreover, in the whole series, the integrative analysis of aCGH and NGS enabled the identification of cryptic recurrent deletions in 2p23.3 (DNMT3A; n = 2.8%), 4q24 (TET2; n = 10%) 17p13 (TP53; n = 8.5%), 21q22 (RUNX1; n = 7%), and Xp11.4 (BCOR; n = 2.8%), while mutations in the non-deleted allele where found only in DNMT3A (n = 1), TET2 (n = 3), and TP53 (n = 4). These cryptic abnormalities were detected mainly in patients with normal (45%) or non-informative (15%) karyotype by conventional cytogenetics, except for those with TP53 deletion and mutation (15%), which had a complex karyotype. In addition to well-known copy number defects, the presence of chromothripsis involving chromosome 13 was a novel recurrent change in high-risk MDS patients. Array CGH analysis revealed the presence of cryptic abnormalities in genomic regions where MDS-related genes, such as TET2, DNMT3A, RUNX1 and BCOR, are located. PMID:27741277

  14. Identification of Patients at Very Low Risk of Local Recurrence After Breast-Conserving Surgery

    International Nuclear Information System (INIS)

    Purpose: To identify clinical and pathological factors that identify groups of women with stage I breast cancer with a 5-year risk of local recurrence (LR) ≤1.5% after breast-conserving therapy (BCS) plus whole-breast radiation therapy (RT). Methods and Materials: Study subjects were 5974 patients ≥50 years of age whose cancer was diagnosed between 1989 and 2006, and were referred with pT1 pN0 invasive breast cancer treated with BCS and RT. Cases of 5- and 10-year LR were examined using Kaplan-Meier methods. Recursive partitioning analysis was performed in patients treated with and without endocrine therapy to identify combinations of factors associated with a 5-year LR risk ≤1.5%. Results: The median follow-up was 8.61 years. Median age was 63 years of age (range, 50 to 91). Overall 5-year LR was 1.5% (95% confidence interval [CI], 1.2%-1.9%) and 10-year LR was 3.4% (95% CI, 2.8%-4.0%). Of 2830 patients treated with endocrine therapy, patient subsets identified with 5-year LR ≤1.5% included patients with grade 1 histology (n=1038; LR, 0.2%; 95% CI, 0%-0.5%) or grade 2 histology plus ≥60 years of age (n=843; LR, 0.5%; 95% CI, 0%-1.0%). Ten-year LR for these groups were 0.8% (95% CI, 0.1%-1.6%) and 0.9% (95% CI, 0.2%-1.6%), respectively. Of 3144 patients treated without endocrine therapy, patients with grade 1 histology plus clear margins had 5-year LR ≤1.5% (n=821; LR, 0.6%; 95% CI, 0.1%-1.2%). Ten-year LR for this group was 2.2% (95% CI, 1.0%-3.4%). Conclusions: Histologic grade, age, margin status, and use of endocrine therapy identified 45% of a population-based cohort of female patients over age 50 with stage I breast cancer with a 5-year LR risk ≤1.5% after BCS plus RT. Prospective study is needed to evaluate the safety of omitting RT in patients with such a low risk of LR

    Jacqueline M Wallace

    Full Text Available Women with specific adverse pregnancy outcomes in their first pregnancy may be receptive to inter-pregnancy weight management guidance aimed at preventing these complications reoccurring in subsequent pregnancies. Thus the association between inter-pregnancy weight change and the risk of recurrent pregnancy complications at the second pregnancy was investigated in a retrospective cohort study of 24,520 women with their first-ever and second consecutive deliveries in Aberdeen using logistic regression. Compared with women who were weight stable, weight loss (>2BMI units between pregnancies was associated with an increased risk of recurrent small for gestational age (SGA birth and elective Cesarean-section, and was protective against recurrent pre-eclampsia, placental oversize and large for gestational age (LGA birth. Conversely weight gain (>2BMI units between pregnancies increased the risk of recurrent gestational hypertension, placental oversize and LGA birth and was protective against recurrent low placental weight and SGA birth. The relationships between weight gain, and placental and birth weight extremes were evident only in women with a healthy weight at first pregnancy (BMI<25units, while that between weight gain and the increased risk of recurrent gestational hypertension was largely independent of first pregnancy BMI. No relationship was detected between inter-pregnancy weight change and the risk of recurrent spontaneous preterm delivery, labour induction, instrumental delivery, emergency Cesarean-section or postpartum hemorrhage. Therefor inter-pregnancy weight change impacts the risk of recurrent hypertensive disorders, SGA and LGA birth and women with a prior history of these specific conditions may benefit from targeted nutritional advice to either lose or gain weight after their first pregnancy.

    The identification of reliable transcriptome biomarkers requires the simultaneous consideration of regulatory and target elements including microRNAs (miRNAs), transcription factors (TFs), and target genes. A novel approach that integrates multivariate survival analysis, feature selection, and regulatory network visualization was used to identify reliable biomarkers of ovarian cancer survival and recurrence. Expression profiles of 799 miRNAs, 17,814 TFs and target genes and cohort clinical records on 272 patients diagnosed with ovarian cancer were simultaneously considered and results were validated on an independent group of 146 patients. Three miRNAs (hsa-miR-16, hsa-miR-22*, and ebv-miR-BHRF1-2*) were associated with both ovarian cancer survival and recurrence and 27 miRNAs were associated with either one hazard. Two miRNAs (hsa-miR-521 and hsa-miR-497) were cohort-dependent, while 28 were cohort-independent. This study confirmed 19 miRNAs previously associated with ovarian cancer and identified two miRNAs that have previously been associated with other cancer types. In total, the expression of 838 and 734 target genes and 12 and eight TFs were associated (FDR-adjusted P-value cancer survival and recurrence, respectively. Functional analysis highlighted the association between cellular and nucleotide metabolic processes and ovarian cancer. The more direct connections and higher centrality of the miRNAs, TFs and target genes in the survival network studied suggest that network-based approaches to prognosticate or predict ovarian cancer survival may be more effective than those for ovarian cancer recurrence. This study demonstrated the feasibility to infer reliable miRNA-TF-target gene networks associated with survival and recurrence of ovarian cancer based on the simultaneous analysis of co-expression profiles and consideration of the clinical characteristics of the patients.

    1992-03-14

    The results of a follow up study of 155 Dutch children who visited the emergency room of an urban paediatric hospital after experiencing their first febrile seizure are presented. Median follow up time was 38 months (range 27-60). Of these 155 initially untreated children 58 (37%) suffered at least one, 47 (30%) at least two and 27 (17%) at least three recurrent seizures. The recurrence hazard after any seizure was highest in the first six months, and dropped markedly after 6 months without seizures. The effect of the various postulated risk factors on the occurrence of any recurrent seizure and three or more recurrences was assessed. A first degree family history of febrile or nonfebrile seizures appears to be a predictor of multiple recurrences; an age of at least 30 months and a temperature of 40.0 degrees C or higher at the initial seizure are associated with a decreased risk. Several factors act together on the risk of recurrent seizures, sometimes in opposite directions. By considering the action of all relevant factors (age at onset, family history and features of the initial febrile seizure) subgroups of children with one year seizure recurrence rates as low as 15% and as high as 48% were identified.

    AIM: To find the risk factors related to the reproliferation of the pterygial tissue after excision and graft surgery.METHODS: Charts of 130 eyes of 130 patients who had pterygial excision from March 2006 to April 2011 were reviewed. Preoperative pterygium morphology, surgical methods, and adjunctive treatments were statistically analyzed for their relationship with recurrence.RESULTS: During the follow-up period, recurrence was observed in 20 eyes(15.4%). None of the preoperative morphologic features were affected the rate of the recurrence. However, an age <40y [P =0.085, odds ratio(OR) 3.609, 95% confidence interval(CI) 0.838-15.540]and amniotic membrane graft instead of conjunctival autograft(P =0.002, OR 9.093, 95% CI 2.316-35.698) were statistically significant risk factors for recurrence.Multivariate analysis revealed that intraoperative mitomycin C(MMC)(P =0.072, OR 0.298, 95% CI 0.080-1.115)decreased the rate of recurrence. CONCLUSION: Younger age is a risk factor for reproliferation of pterygial tissue after excision and amniotic membrane transplantation(AMT) are less effective in preventing recurrence of pterygium after excision based on the comparison between conjunctival autograft and AMT. Intraoperative MMC application and conjunctival autograft reduce recurrence.

    Clostridium difficile infection (CDI) is one of the leading causes of hospital-acquired infections in recent times. Hematopoietic stem cell transplantation (HSCT) confers increased risk for CDI because of prolonged hospital stay, immunosuppression, the need to use broad-spectrum antibiotics and a complex interplay of preparative regimen and GvHD-induced gut mucosal damage. Our study evaluated risk factors (RF) for recurrent CDI in HSCT recipients given the ubiquity of traditional RF for CDI in this population. Of the 499 allogeneic HSCT recipients transplanted between 2005 and 2012, 61 (12%) developed CDI within 6 months before transplant or 2 years after transplant and were included in the analysis. Recurrent CDI occurred in 20 (33%) patients. One year incidence of CDI recurrence was 31%. Multivariable analyses identified the number of antecedent antibiotics other than those used to treat CDI as the only significant RF for recurrence (hazard ratio 1.96, 95% confidence interval 1.09-3.52, P=0.025). Most recurrences occurred within 6 months of the first CDI, and the recurrence of CDI was associated with a trend for increased risk of mortality. This prompts the need for further investigation into secondary prophylaxis to prevent recurrent CDI. PMID:26726944

    Objective To observe the influencing factors of recurrence and metastasis for postoperative breast cancer high-risk population, and TCM regimen of syndrome differentiation and treatment was used to validate its significance for the prevention of recurrence and metastasis. Methods The influencing factors of recurrence and metastasis of 178 postoperative breast cancer high-risk cases with positive hormone receptor were studied. The recurrence and metastasis, disease-free survival and accumulative points of TCM symptoms of integrated group (with TCM syndrome differentiation and endocrine therapy) and western medicine group (with endocrine therapy) were compared. Results Lymph node metastasis, cancer staging and TCM therapy had influence on the disease-free survival rate of postoperative breast cancer high-risk patients. TCM therapy was the independent prognostic factor for disease-free survival. 3-year recurrence and metastasis rate was lower in integrated group than that in western medicine group, with statistical difference (P=0.03). The total accumulative points of TCM symptoms in both two groups decreased after treated for 3 and 6 months, integrated group showed greater significance. TCM therapy was better for the treatment of irritability, hot flash and perspiration, good for spontaneous perspiration and insomnia, but poor in dry mouth, bitter taste in mouth and fatigue. Conclusion Lymph node metastasis, cancer staging and TCM therapy are main influencing factors for recurrence and metastasis. TCM therapy with regimen of syndrome differentiation and treatment can reduce 3-year recurrence and metastasis rate, improve TCM symptoms, especially is significant for the improvement of irritability, hot flash and perspiration.%目的:观察乳腺癌术后高危人群复发转移的影响因素,并应用中医辨证论治方案干预,观察其降低复发转移率的有效性。方法对178例激素受体阳性乳腺癌术后高危人群复发转移影响因素进

    Full Text Available The purpose of this study was to identify risk factors for recurrence of prostate adenocarcinoma after HIFU therapy. Material and methods: Material for the study was obtained from patients diagnosed with adenocarcinoma before and after HIFU treatment. Morphological study was conducted using a standard staining, and immunohistochemical markers: PCNA, Amacr, E-cadherin, Bel2, Andr, Estr, VEGF, P53, PCNA. Results: After treatment in 89% of patients with initial prostate volume greater than 50 cc the signs of recurrence of adenocarcinoma were showed. At low risk for D'Amico after treatment the expression of proliferation markers, VEGF, Amacr significantly decreased. With a high degree of risk — increased expression of Bel2. After treatment the expression of the following markers: PCNA, Amacr, VEGF significantly increased in the group of patients with the presence of invasion. Conclusion: Patients with initial prostate volume less than 50 cc, low risk to D'Amico, the lack of perineural and perivascular invasion have a low risk of recurrence after HIFU therapy; patients at high risk for D'Amico, the presence of perineural and perivascular invasion initial and prostate volume greater than 50 cc, low-grade cribriform form of adenocarcinoma have a high risk of recurrence of adenocarcinoma. Recurrence of adenocarcinoma develops independently of the period after HIFU therapy.

    Full Text Available Breast cancer recurrence (BCR is a common treatment outcome despite curative-intent primary treatment of non-metastatic breast cancer. Currently used prognostic and predictive factors utilize tumor-based markers, and are not optimal determinants of risk of BCR. Germline-based copy number aberrations (CNAs have not been evaluated as determinants of predisposition to experience BCR. In this study, we accessed germline DNA from 369 female breast cancer subjects who received curative-intent primary treatment following diagnosis. Of these, 155 experienced BCR and 214 did not, after a median duration of follow up after breast cancer diagnosis of 6.35 years (range = 0.60-21.78 and 8.60 years (range = 3.08-13.57, respectively. Whole genome CNA genotyping was performed on the Affymetrix SNP array 6.0 platform. CNAs were identified using the SNP-Fast Adaptive States Segmentation Technique 2 algorithm implemented in Nexus Copy Number 6.0. Six samples were removed due to poor quality scores, leaving 363 samples for further analysis. We identified 18,561 CNAs with ≥1 kb as a predefined cut-off for observed aberrations. Univariate survival analyses (log-rank tests identified seven CNAs (two copy number gains and five copy neutral-loss of heterozygosities, CN-LOHs showing significant differences (P<2.01×10(-5 in recurrence-free survival (RFS probabilities with and without CNAs.We also observed three additional but distinct CN-LOHs showing significant differences in RFS probabilities (P<2.86×10(-5 when analyses were restricted to stratified cases (luminal A, n = 208 only. After adjusting for tumor stage and grade in multivariate analyses (Cox proportional hazards models, all the CNAs remained strongly associated with the phenotype of BCR. Of these, we confirmed three CNAs at 17q11.2, 11q13.1 and 6q24.1 in representative samples using independent genotyping platforms. Our results suggest further investigations on the potential use of germline DNA

    Lung cancer, the leading cause of cancer-related death, still lacks reliable biomarkers. Apurinic/apyrimidinic endonuclease 1/Ref-1 is a multifunctional protein involved in the base excision repair of DNA damaged by oxidative stress or alkylating compounds, as well as in the regulation of multiple transcription factors. To validate apurinic/apyrimidinic endonuclease 1/Ref-1 as a biomarker for prediction of lung cancer recurrence, we studied 42 patients who received curative resection and mediastinal lymph node dissection for stage I non-small-cell lung cancer. They were divided into 2 groups based on recurrence, and compared by immunohistochemistry staining of paraffin-embedded tissues and Western blot analysis. Immunohistochemical staining showed a significant difference between the cytoplasm and nucleus in patients who had a recurrence compared to those with nonrecurrent adenocarcinoma. In Western blot analysis, the recurrent adenocarcinoma group showed increased expression of apurinic/apyrimidinic endonuclease 1/Ref-1 in cytoplasm, nucleus, and in total. This indicates that apurinic/apyrimidinic endonuclease 1/Ref-1 is unregulated in recurrent stage I adenocarcinoma. For clinical application as a prognostic marker for non-small-cell lung cancer, further investigation into the role of apurinic/apyrimidinic endonuclease 1/Ref-1 in carcinogenesis is needed in an expanded prospective study.

    AIM: To assess the clinical role of monoclonal immunoscintigraphy for the detection of metastasis and recurrence of colorectal cancer. METHODS: Monoclonal immunoscintigraphy was performed in patients operated on for colorectal adenocarcinomasuspected of local recurrence and metastatic disease. The results were compared with conventional diagnostics. RESULTS: Immunoscintigraphic investigation was done in 53 patients. Tumor recurrence occurred in 38 patients, and was confirmed by other diagnostic modalities in 35. In 15 patients, immunoscintigraphic findings were negative, and confirmed in 14 with other diagnostic methods. Comparative analysis confirmed good correlation of immunoscintigraphic findings and the results of conventional diagnostics and the level of tumor marker carcinoembryonic antigen. Statistical analysis of parameters of radiopharmaceutical groups imacis, indimacis and oncoscint presented homogenous characteristics all of three radiopharmaceuticals. The analysis of immunoscintigraphic target focus was clearly improved using tomography. CONCLUSION: Immunoscintigraphy is highly specific and has a good predictive value in local recurrence of colorectal cancer.

    2013-06-15

    To investigate the patterns of locoregional recurrence of pathologic T3N0 (pT3N0) lower rectal cancer omitting postoperative radiotherapy (RT) and explore the potential of modification of a RT field. From Jan 2003 to Nov 2011, 35 patients omitting preoperative or postoperative RT for pT3N0 lower rectal cancer were included. We defined the lower rectal cancer as the tumor with the inferior margin located below the virtual line-a convergent level between rectal wall and levator ani muscle. All patients had radiologic examinations for recurrence evaluation during the follow-up duration. The median follow-up duration was 66.4 months (range, 1.4 to 126.1 months). Eight (22.9%) of the 35 patients had recurrence. Three (8.6%) was local recurrence (LR) only, 3 (8.6%) was distant metastasis (DM) only, and 2 (5.7%) was LR with DM. All LR were located at primary tumor sites. The overall survival rate, LR-free survival rate, and DM-free survival rate at 5 years was 79.8%, 83%, and 87%, respectively. All LR developed from tumors over 5 cm. However, there was no statistical significance (p = 0.065). There was no other risk factor for LR. Even though the patients included in this study had pathologically favorable pT3N0 rectal cancer, LR developed in 14.3% of patients. Most of the LR was located at primary tumor sites prior to surgery. Based on these findings, it might seem reasonable to consider postoperative RT with a smaller radiation field to the primary tumor site rather than the conventional whole pelvic irradiation.

    A controlled randomized clinical trial was conducted to examine the efficacy of topical low dose heparin (0.125 gm./l., 25,000 units per l.) as prophylaxis against recurrent noninvasive (stage Ta) transitional cell bladder cancer. Transurethral tumor resection was done with irrigation fluid...... containing either 1.5% glycine with heparin or glycine solution alone. Tumor recurrence was determined by cystoscopy 4 to 6 months later. There were 70 patients evaluated: 38 in the heparin and 32 in the control group, respectively. The recurrence rate (heparin 74%, control 66%) and the median number...... of recurrences (heparin 3, range 1 to 15 and control 3, range 1 to 30) were similar (p greater than 0.05) in the 2 groups of patients. These observations show that low dose heparin administered in the irrigation fluid during transurethral resection does not decrease the recurrence rate of noninvasive (stage Ta...

    Cancer stem cells (CSCs) are a subpopulation of cancer cells with many clinical implications in most cancer types. One important clinical implication of CSCs is their role in cancer metastases, as reflected by their ability to initiate and drive micro and macro-metastases. The other important contributing factor for CSCs in cancer management is their function in causing treatment resistance and recurrence in cancer via their activation of different signalling pathways such as Notch, Wnt/β-catenin, TGF-β, Hedgehog, PI3K/Akt/mTOR and JAK/STAT pathways. Thus, many different therapeutic approaches are being tested for prevention and treatment of cancer recurrence. These may include treatment strategies targeting altered genetic signalling pathways by blocking specific cell surface molecules, altering the cancer microenvironments that nurture cancer stem cells, inducing differentiation of CSCs, immunotherapy based on CSCs associated antigens, exploiting metabolites to kill CSCs, and designing small interfering RNA/DNA molecules that especially target CSCs. Because of the huge potential of these approaches to improve cancer management, it is important to identify and isolate cancer stem cells for precise study and application of prior the research on their role in cancer. Commonly used methodologies for detection and isolation of CSCs include functional, image-based, molecular, cytological sorting and filtration approaches, the use of different surface markers and xenotransplantation. Overall, given their significance in cancer biology, refining the isolation and targeting of CSCs will play an important role in future management of cancer.

  1. Genetic Risk for Recurrent Urinary Tract Infections in Humans: A Systematic Review

    Directory of Open Access Journals (Sweden)

    M. Zaffanello

    2010-01-01

    Full Text Available Urinary tract infections (UTIs are a frequent cause of morbidity in children and adults and affect up to 10% of children; its recurrence rate is estimated at 30–40%. UTI may occur in up to 50% of all women in their lifetimes and frequently require medication. Recent advances have suggested that a deregulation of candidate genes in humans may predispose patients to recurrent UTI. The identification of a genetic component of UTI recurrences will make it possible to diagnose at-risk adults and to predict genetic recurrences in their offspring. Six out of 14 genes investigated in humans may be associated with susceptibility to recurrent UTI in humans. In particular, the HSPA1B, CXCR1 & 2, TLR2, TLR4, TGF-1 genes seem to be associated with an alteration of the host response to UTIs at various levels.

  2. Mechanisms driving local breast cancer recurrence in a model of breast-conserving surgery.

    2012-02-03

    OBJECTIVE: We aimed to identify mechanisms driving local recurrence in a model of breast-conserving surgery (BCS) for breast cancer. BACKGROUND: Breast cancer recurrence after BCS remains a clinically significant, but poorly understood problem. We have previously reported that recurrent colorectal tumours demonstrate altered growth dynamics, increased metastatic burden and resistance to apoptosis, mediated by upregulation of phosphoinositide-3-kinase\\/Akt (PI3K\\/Akt). We investigated whether similar characteristics were evident in a model of locally recurrent breast cancer. METHODS: Tumours were generated by orthotopic inoculation of 4T1 cells in two groups of female Balb\\/c mice and cytoreductive surgery performed when mean tumour size was above 150 mm(3). Local recurrence was observed and gene expression was examined using Affymetrix GeneChips in primary and recurrent tumours. Differential expression was confirmed with quantitative real-time polymerase chain reaction (qRT-PCR). Phosphorylation of Akt was assessed using Western immunoblotting. An ex vivo heat shock protein (HSP)-loaded dendritic cell vaccine was administered in the perioperative period. RESULTS: We observed a significant difference in the recurrent 4T1 tumour volume and growth rate (p < 0.05). Gene expression studies suggested roles for the PI3K\\/Akt system and local immunosuppression driving the altered growth kinetics. We demonstrated that perioperative vaccination with an ex vivo HSP-loaded dendritic cell vaccine abrogated recurrent tumour growth in vivo (p = 0.003 at day 15). CONCLUSION: Investigating therapies which target tumour survival pathways such as PI3K\\/Akt and boost immune surveillance in the perioperative period may be useful adjuncts to contemporary breast cancer treatment.

  3. Radiation therapy for non-small cell lung cancer with postoperative intrathoracic recurrence

    International Nuclear Information System (INIS)

    We reviewed patients with intrathoracic recurrence of non-small cell lung cancer after surgery, with reference to the feasibility of radiotherapy. The series consisted of 46 patients (39 males and 7 females) treated by radiotherapy from 1982 to 1995. Histology included squamous cell carcinoma (28 patients), adenocarcinoma (17), and large cell carcinoma (1). Clinical stage by UICC classification (1987) was as follows: stage I (2 patients), stage II (1), stage IIIa (13), stage IIIb (23), and stage IV (7). Recurrences were noted in bronchial stump (18 patients) and surgical scar (4). Metastases occurred in hilar-mediastinal lymphnodes (15), lung fields (7), and pleuropericardium (2). The mean interval from surgery to recurrence was 27 months. Delivered dose ranged from 45 to 80 Gy, and 19 patients received combined chemotherapy. Therapeutic results were as follows: complete response in 16 patients, partial response in 27, no response in 12 and progressive disease in 1. Overall 2- and 5-year survival rates were 17% and 11%, respectively, and 10 months in MST. On univariate analysis, significant prognostic factors were sex, stage at recurrence, recurrence pattern, performance status and initial response to radiotherapy, while multivariate analysis showed sex and initial response. From these data, we are encouraged by effective radiotherapy for postoperative intrathoracic recurrence of non-small cell lung cancer, especially in patients with stump or lymphnode recurrence.

    The study was aimed to the improvement of the diagnosis and treatment of patients with prostate cancer (PC). The study included 46 patients with recurrent prostate cancer after radical prostatectomy (RPE). The examination included contrast enhanced magnetic resonance imaging (endorectal coil 1.5T) and hystoscanning. All patients had local recurrence confirmed by the morphologically results of transrectal biopsy of the area of vesicourethral anastomosis. All patients underwent high-intensity focused ultrasound (HIFU). Before RPE, protate volume ranged from 21 to 102 cm3. The median age was 62 (46-68) years. PSA levels before a HIFU session ranged from 0.4 to 18 ng/ml. Nadir PSA level after 3 months of follow up was 0.1 ng/ml. Five-year disease-free survival in patients with locally recurrent prostate cancer after HIFU in the group of low cancer risk was 10 (81%), moderate risk--18 (57%), high risk--12 (42%). Contrast enhanced magnetic resonance imaging and hystoscanning are highly informative methods for diagnosis of local recurrence after radical prostatectomy, and HIFU can be categorized as highly effective treatment.

    Objective To determine how length of anticoagulation and clinical presentation of venous thromboembolism influence the risk of recurrence after anticoagulant treatment is stopped and to identify the shortest length of anticoagulation that reduces the risk of recurrence to its lowest level. Design Pooled analysis of individual participants’ data from seven randomised trials. Setting Outpatient anticoagulant clinics in academic centres. Population 2925 men or women with a first venous thromboembolism who did not have cancer and received different durations of anticoagulant treatment. Main outcome measure First recurrent venous thromboembolism after stopping anticoagulant treatment during up to 24 months of follow-up. Results Recurrence was lower after isolated distal deep vein thrombosis than after proximal deep vein thrombosis (hazard ratio 0.49, 95% confidence interval 0.34 to 0.71), similar after pulmonary embolism and proximal deep vein thrombosis (1.19, 0.87 to 1.63), and lower after thrombosis provoked by a temporary risk factor than after unprovoked thrombosis (0.55, 0.41 to 0.74). Recurrence was higher if anticoagulation was stopped at 1.0 or 1.5 months compared with at 3 months or later (hazard ratio 1.52, 1.14 to 2.02) and similar if treatment was stopped at 3 months compared with at 6 months or later (1.19, 0.86 to 1.65). High rates of recurrence associated with shorter durations of anticoagulation were confined to the first 6 months after stopping treatment. Conclusion Three months of treatment achieves a similar risk of recurrent venous thromboembolism after stopping anticoagulation to a longer course of treatment. Unprovoked proximal deep vein thrombosis and pulmonary embolism have a high risk of recurrence whenever treatment is stopped. PMID:21610040

    The objective of this study was to evaluate the correlation between 25-OH vitamin D and ovarian cancer as a diagnostic marker or recurrence disease marker. We studied the following: (1) 61 women without gynecologic diseases, (2) 45 women affected by benign ovarian disease, (3) 46 women with recent diagnosis of ovarian cancer, (4) 26 follow-up women with recurrent ovarian cancer, and (5) 32 follow-up women with stable ovarian cancer. The 25-OH vitamin D was quantified with LUMIPULSE® G 25-OH vitamin D on LUMIPULSE® G 1200 (Fujirebio, Japan). As a threshold value, identified by ROC curve analysis, 20.2 ng/mL (sensitivity 73.3 %, specificity 84 %) was chosen corresponding to the limit between sufficient and insufficient 25-OH vitamin D according to the WHO. Low 25-OH vitamin D levels were observed in 26 % of women without gynecologic diseases, in 80 % of women with recent diagnosis of ovarian cancer and in 24 % women affected by benign ovarian diseases (p < 0.001). The follow-up study showed an insufficient level of 25-OH vitamin D in 73 % women with recurrent ovarian cancer and in 47 % women with stable ovarian cancer (p < 0.0003). This study showed that patients with ovarian cancer are often insufficient in 25-OH vitamin D compared to women with benign ovarian diseases. The women with recurrent ovarian cancer presented more often low levels compared to women with stable ovarian cancer. This study suggests that 25-OH vitamin D, due to its antiproliferative properties, can be a good marker for ovarian cancer also.

    Crohn's disease (CD) is a chronic inflammatory disease of the digestive tract with systemic manifestations. Etiology is unknown, even if immunological, genetic and environmental factors are involved. The majority of CD patients require surgery during their lifetime due to progressive bowel damage, but, even when all macroscopic lesions have been removed by surgery, the disease recurs in most cases. Postoperative management represents therefore a crucial mean for preventing recurrence. Several drugs and approaches have been proposed to achieve this aim. Endoscopic inspection of the ileocolic anastomosis within 1 year from surgery is widely encouraged, given that endoscopic recurrence is one of the greatest predictors for clinical recurrence. A strategy should be planned only after stratifying patients according to their individual risk of recurrence, avoiding unnecessary therapies when possible benefits are reduced, and selecting high-risk patients for more aggressive intervention.

    ratio,number of MLN metastasis > 3,multiple station metastasis,trans-regional metastasis and multi-zonal metastasis.A multivariate analysis using Cox regression identified 2 independent factors of prognosis:transregional MLN metastasis (P =0.035) and number of MLN metastasis > 3 (P =0.045).The recurrence risk of patients with trans-regional MLN metastasis was 2.0 times higher than those with regional MLN metastasis while the recurrence risk of patients with number of MLN metastasis > 3 was 2.2 times higher than those with number of MLN metastasis of 1-3.Conclusion Recurrence risk of stage Ⅲ A-N2 non-small cell lung cancer (NSCLC) after curative resection may be estimated by location and number of MLN metastasis.And the subgroup with trans-regional MLN metastasis and number of MLN metastasis > 3 carries the highest risk of recurrence.

  10. Recurrence and mortality according to Estrogen Receptor status for breast cancer patients undergoing conservative surgery. Ipsilateral breast tumour recurrence dynamics provides clues for tumour biology within the residual breast

    International Nuclear Information System (INIS)

    the study was designed to determine how tumour hormone receptor status affects the subsequent pattern over time (dynamics) of breast cancer recurrence and death following conservative primary breast cancer resection. Time span from primary resection until both first recurrence and death were considered among 2825 patients undergoing conservative surgery with or without breast radiotherapy. The hazard rates for ipsilateral breast tumour recurrence (IBTR), distant metastasis (DM) and mortality throughout 10 years of follow-up were assessed. DM dynamics displays the same bimodal pattern (first early peak at about 24 months, second late peak at the sixth-seventh year) for both estrogen receptor (ER) positive (P) and negative (N) tumours and for all local treatments and metastatic sites. The hazard rates for IBTR maintain the bimodal pattern for ERP and ERN tumours; however, each IBTR recurrence peak for ERP tumours is delayed in comparison to the corresponding timing of recurrence peaks for ERN tumours. Mortality dynamics is markedly different for ERP and ERN tumours with more early deaths among patients with ERN than among patients with ERP primary tumours. DM dynamics is not influenced by the extent of conservative primary tumour resection and is similar for both ER phenotypes across different metastatic sites, suggesting similar mechanisms for tumour development at distant sites despite apparently different microenvironments. The IBTR risk peak delay observed in ERP tumours is an exception to the common recurrence risk rhythm. This suggests that the microenvironment within the residual breast tissue may enforce more stringent constraints upon ERP breast tumour cell growth than other tissues, prolonging the latency of IBTR. This local environment is, however, apparently less constraining to ERN cells, as IBTR dynamics is similar to the corresponding recurrence dynamics among other distant tissues

    Adjuvant chemotherapy for breast cancer after surgery has effectively lowered metastatic recurrence rates. However, a considerable proportion of women suffer recurrent cancer at distant metastatic sites despite adjuvant treatment. Identification of the genes crucial for tumor response to specific...... of LAPTM4B resulted in sequestration of the anthracycline doxorubicin, delaying its appearance in the nucleus. Overexpression of these two genes was associated with poor tumor response to anthracycline treatment in a neoadjuvant chemotherapy trial in women with primary breast cancer. Our results suggest...... chemotherapy drugs is a challenge but is necessary to improve outcomes. By using integrated genomics, we identified a small number of overexpressed and amplified genes from chromosome 8q22 that were associated with early disease recurrence despite anthracycline-based adjuvant chemotherapy. We confirmed...

    Clinical trials of boron neutron capture therapy (BNCT) for recurrent breast cancers are considered at Japan Research Reactor No. 4 (JRR-4). In this study, the irradiation technique for a total mastectomy patient with recurrent cancer was optimized by dosimetric calculations using JAEA computational dosimetry system (JCDS). The evaluation was performed using an en face technique and a tangents technique with thermal neutron beam mode at JRR-4. The results revealed that equivalent doses of lung, heart, liver and skin were similar in each irradiation technique due to the isotropic scattering of thermal neutrons in the body. On the other hand, the irradiation time with the tangents technique was a few times longer than with the en face technique. We concluded that the en face technique was an optimal irradiation technique for recurrent breast cancers using thermal neutron beam mode in terms of shorter irradiation time and easier patient positioning.

    Full Text Available BACKGROUND: Studies show that poststroke depression (PSD increases mortality risk at 1 year. However, whether PSD increases the risk of recurrent stroke at 1 year remains unclear. This study was to investigate whether PSD at 2 weeks following a stroke could increase risk of recurrent stroke at 1 year. METHODS AND RESULTS: This was a multi-centered prospective cohort study. A total of 2306 patients with acute stroke were enrolled in our study. PSD was diagnosed according to the criteria set by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV. The outcomes of recurrent stroke were followed up via face-to-face or phone interview. A total of 1713 patients had complete follow-up data, with 481 (28.1% cases of PSD and 158 (9.2% cases of cumulative recurrent stroke at 1 year. Multivariate logistic regression analysis showed a 49% increase of OR of recurrent stroke at 1 year in patients with PSD, compared to patients without PSD following a stroke (OR=1.49, 95%CI: 1.03-2.15. There was no significant correlation between anti-depressant drugs and the risk of recurrent stroke at 1 year following a stroke (OR=1.96, 95%: CI 0.95-4.04. CONCLUSIONS: Based on the DSM-IV diagnostic criteria, nearly 3 out of 10 hospitalized stroke patients in China were diagnosed with PSD at 2 weeks following a stroke. PSD is associated with a higher risk of recurrent stroke at 1 year. Our study did not find benefit of anti-depressant drugs in reducing such risk.

    OBJECTIVE To evaluate the role of whole-body {18F} fluro-2-dexoxyglucose (FDG) positron emission tomography (PET) scans in the detection of recurrent cervical cancer.METHODS Between June, 2000 and January, 2006, 25 patients had undergone a PET scan at the Peking Union Medical College Hospital to evaluate possible recurrent cervical cancer. All the PET findings were reviewed and compared to available clinical data to classify each PET scan result as a true positive, true negative, false positive, or false negative.RESULTS A total of 38 PET scans were conducted on the 25patients whose median age was 46 years. The Stage distributions were IA (n = 1), IB (n = 11), IIA (n = 5), IIB (n = 4), IIIB (n = 2), WB (n= 1), and unknown Stage (n = 1). There were 22 cases of squamous cell carcinoma and 3 cases of adenocarcinoma resulting in 9 true positive PET scans, 27 true negatives, 2 false positives and no false negatives. The sensitivity of the FDG PET scans for detecting recurrent cervical cancer was 100%, specificity 93.1%, positive predictive value 81.8%, and negative predictive value 100%.CONCLUSION The whole body FDG PET scans are a sensitive and specific imaging modality for the detection of recurrent cervical cancer. However the cost of PET scans is too high at this time. A large prospective study will determine whether this modality should be used routinely and take the place of other imaging methods in the early detection of recurrent cervical carcinoma

    2006-01-01

    Objective To evaluate the efficacy of treatment options for patients with recurrent ovarian cancer. Methods From 1990 to 2000, 54 patients with recurrent ovarian cancer primarily treated in Peking Union Medical College Hospital were selected and reviewed. All the clinical data related to the recurrent tumor were collected. Twoside P values for differences in survival were calculated by the Cox regression model. Results The platinum-free interval > 6 months and the surgery followed by salvage chemotherapy prolonged survival time of the patients with recurrent ovarian cancer (95% CI = 0. 153-0. 987, P = 0. 047; 95 % CI = 1.611-10. 914,P =0. 003, respectively). The increased number of chemotherapy cycles ( > 10 months) offered some benefit on the survival (95 % CI = 0. 110-1. 090, P = 0. 070). The initiation of treatment and chemotherapy regiments failed to demonstrate an improvement in survival. Conclusion The treatment options for patients with recurrent ovarian cancer depend on the platinum-free-interval of the patients. A strategy of secondary surgical cytoreduction followed by salvage chemotherapy is suggested for the patients with platinum-sensitive disease.

  5. A clinical study of radiotherapy with CHFU for advanced and recurrent breast cancer

    International Nuclear Information System (INIS)

    We have investigated the usefulness of combination therapy with radiation and CHFU for advanced and recurrent breast cancer according to a clinical cotrolled multicenter trial from 1982 to 1984. One hundred cases were registered and 82 of them were availabe. Treatment sites were the lymph nodes, skin, bone and lung, and the overall response rate was 58% in CR and 19% in PR, while the duration of remission was 18 weeks in CR. Side effects were found in 10% of the patients. Combination therapy with radiation and HCFU may be useful in multimodal tretment for advanced recurrent breast cancer. (author)

    AIM: To analyze, retrospectively in a population-based study, the management and survival of patients with recurrent rectal cancer initially treated with a macroscopically radical resection obtained with total mesorectal excision (TME).METHODS: All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection (632 patients) were selected from the Amsterdam Cancer Registry. For patients with recurrent disease, information on treatment of the recurrence was collected from the medical records.RESULTS: Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients (10%). Thirty-two patients had an isolated local recurrence. Ten of these 32 patients (31%) underwent radical re-resection and experienced the highest survival (three quarters survived for at least 3 years). Eight patients (25%) underwent non-radical surgery (median survival 24 too), seven patients (22%) were treated with radio- and/or chemotherapy without surgery (median survival 15 mo) and seven patients (22%) only received best supportive care (median survival 5 mo). Distant dissemination occurred in 124 patients (20%) of whom 30 patients also had a local recurrence. The majority (54%) of these patients were treated with radio- and/or chemotherapy without surgery (median survival 15 mo). Twenty-seven percent of these patients only received best supportive care (median survival 6 mo), while 16% underwent surgery for their recurrence. Survival was best in the latter group (median survival 32 mo).CONCLUSION: Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME, patients can benefit from additional treatment, especially if a radical resection is feasible.

    AIM:To investigate the patterns and decisive prognostic factors for local recurrence of rectal cancer treated with a multidisciplinary team (MDT) modality.METHODS:Ninety patients with local recurrence were studied,out of 1079 consecutive rectal cancer patients who underwent curative surgery from 1999 to 2007.For each patient,the recurrence pattern was assessed by specialist radiologists from the MDT using imaging,and the treatment strategy was decided after discussion by the MDT.The associations between clinicopathological factors and long-term outcomes were evaluated using both univariate and multivariate analysis.RESULTS:The recurrence pattern was classified as follows:Twenty-seven (30%) recurrent tumors were evaluated as axial type,21 (23.3%) were anterior type,8 (8.9%) were posterior type,and 13 (25.6%) were lateral type.Forty-one patients had tumors that were evaluated as resectable by the MDT and ultimately received surgery,and R0 resection was achieved in 36 (87.8%) of these patients.The recurrence pattern was closely associated with resectability and R0 resection rate (P < 0.001).The recurrence pattern,interval to recurrence,and RO resection were significantly associated with 5-year survival rate in univariate analysis.Multivariate analysis showed that the R0 resection was the unique independent factor affecting long-term survival.CONCLUSION:The MDT modality improves patient selection for surgery by enabling accurate classification of the recurrence pattern; RO resection is the most significant factor affecting long-term survival.

    To assess clinical utility of the 21-gene assay (Oncotype DX® Recurrence Score®), we determined whether women with HER2(−)/ER+ pN1mi breast cancer with low (<18) Recurrence Scores results are given adjuvant chemotherapy in a lower proportion than those with high scores (≥31). This was a multicenter chart review of ≥18 year old women with pN1mi breast cancer, HER2(−)/ER+ tumors, ductal/lobular/mixed histology, with the assay ordered on or after 1 January 2007. One hundred and eighty one patients had a mean age of 60.7 years; 82.9% had ECOG performance status 0; 33.7% had hypertension, 22.7% had osteoporosis, 18.8% had osteoarthritis, and 8.8% had type-2 diabetes. Mean Recurrence Score was 17.8 (range: 0–50). 48.6% had a mastectomy; 55.8% had a lumpectomy. 19.8% of low-risk group patients were recommended chemotherapy vs. 57.9% in the intermediate-risk group and 100% in the high-risk group (p < 0.001). A total of 80.2% of the low-risk group were recommended endocrine therapy alone, while 77.8% of the high-risk group were recommended both endocrine and chemotherapy (p < 0.001). The Oncotype DX Recurrence Score result provides actionable information that can be incorporated into treatment planning for women with HER2(−)/ER+ pN1mi breast cancer. The Recurrence Score result has clinical utility in treatment planning for HER2(−)/ER+ pN1mi breast cancer patients. PMID:25789420

    Background Many researches suggested that obesity increased the risk of breast cancer, but the mechanism was currently unknown. Adipocytokines might mediate the relationship. Our study was aimed to investigate the relationship between serum levels of resistin, adiponectin and leptin and the onset, invasion and metastasis of breast cancer.Methods Blood samples were collected from 80 newly diagnosed, histologically confirmed breast cancer patients and 50 age-matched healthy controls. Serum levels of resistin, adiponectin and leptin were determined by enzyme-linked immunosorbent assays (ELISA); fasting blood glucose (FBG), lipids, body mass index (BMI), and waist circumference (WC) were assayed simultaneously.Results Serum levels of adiponectin ((8.60±2.92) mg/L vs (10.37±2.81) mg/L, P=0.001) and HDL-c were significantly decreased in breast cancer patients in comparison to controls. Serum levels of resistin ((26.35±5.36) μg/L vs (23.32±4.75)μg/L, P=0.000), leptin ((1.35±0.42) μg/L vs (1.06±0.39) μg/L, P=0.003), FBG and triglyceride (TG) in breast cancer patients were increased in contrast to controls, respectively. However, we did not find the significant difference of the serum levels of resistin, adiponectin and leptin between premenopausal breast cancer patients and healthy controls (P=0.091, 0.109 and 0.084, respectively). The serum levels of resistin, adiponectin and leptin were significantly different between patients with lymph node metastasis (LNM) and those without LNM (P=0.001, 0.000 and 0.006, respectively).The stepwise regression analysis indicated that the tumor size had the close correlation with leptin (R2=0.414, P=0.000)and FBG (R2=0.602, P=0.000). Logistic regression analysis showed that reduced serum levels of adiponectin (OR:0.805;95%CI: 0.704-0.921; P=0.001), HDL (OR: 0.087; 95%CI: 0.011-0.691, P=0.021), elevated leptin (OR:2.235;95%CI:1.898-4.526; P=0.004) and resistin (OR: 1.335; 95%CI: 1.114-2.354; P=0.012) increased the risk for

    Recurrent AKI is common among patients after hospitalized AKI and is associated with progressive CKD. In this study, we identified clinical risk factors for recurrent AKI present during index AKI hospitalizations that occurred between 2003 and 2010 using a regional Veterans Administration database in the United States. AKI was defined as a 0.3 mg/dl or 50% increase from a baseline creatinine measure. The primary outcome was hospitalization with recurrent AKI within 12 months of discharge from the index hospitalization. Time to recurrent AKI was examined using Cox regression analysis, and sensitivity analyses were performed using a competing risk approach. Among 11,683 qualifying AKI hospitalizations, 2954 patients (25%) were hospitalized with recurrent AKI within 12 months of discharge. Median time to recurrent AKI within 12 months was 64 (interquartile range 19-167) days. In addition to known demographic and comorbid risk factors for AKI, patients with longer AKI duration and those whose discharge diagnosis at index AKI hospitalization included congestive heart failure (primary diagnosis), decompensated advanced liver disease, cancer with or without chemotherapy, acute coronary syndrome, or volume depletion, were at highest risk for being hospitalized with recurrent AKI. Risk factors identified were similar when a competing risk model for death was applied. In conclusion, several inpatient conditions associated with AKI may increase the risk for recurrent AKI. These findings should facilitate risk stratification, guide appropriate patient referral after AKI, and help generate potential risk reduction strategies. Efforts to identify modifiable factors to prevent recurrent AKI in these patients are warranted.

    Background The World Health Organization (WHO) histological classification for gastric cancer is widely accepted and used. However, its impact on predicting lymph node metastasis and recurrence in early gastric cancer (EGC) is not well studied. Material/Methods From 1987 to 2005, 2873 EGC patients with known WHO histological type who had undergone curative resection were enrolled in this study. In all, 637 well-differentiated adenocarcinomas (WD), 802 moderately-differentiated adenocarcinomas (MD), 689 poorly-differentiated adenocarcinomas (PD), and 745 signet-ring cell adenocarcinomas (SRC) were identified. Results The distribution of demographic and clinical features in early gastric cancer among WD, MD, PD, and SRC were significantly different. Lymph node metastasis was observed in 317 patients (11.0%), with the lymph node metastasis rate being 5.3%, 14.8%, 17.0%, and 6.3% in WD, MD, PD, and SRC, respectively. Univariate and multivariate analyses indicated that gender, tumor size, gross appearance, depth of invasion, and WHO classification were significantly associated with lymph node metastasis. Recurrence was observed in 83 patients (2.9%), with the recurrence rate being 2.2%, 4.5%, 3.0%, and 1.6% in WD, MD, PD, and SRC, respectively. Multivariate analysis confirmed that MD, elevated gross type, and lymph node metastasis were independent risk factors for recurrence in EGC. MD patients showed worse disease-free survival than non-MD patients (P=0.001). Conclusions WHO classification is useful and necessary to evaluate during the perioperative management of EGC. Treatment strategies for EGC should be made prudently according to WHO classification, especially for MD patients. PMID:27595490

    2010-03-01

    Full Text Available Prostate cancer (PC is the second most common cancer in men worldwide. Its prevention and treatment remain a challenge to clinicians. Here we review the relationship of vitamins to PC risk. Many vitamins and related chemicals, including vitamin A, retinoids, several B vitamins, vitamin C, vitamin D and vitamin E have shown their anti-cancer activities as anti-oxidants, activators of transcription factors or factors influencing epigenetic events. Although laboratory tests including the use of animal models showed these vitamins may have anti-PC properties, whether they can effectively prevent the development and/or progression of PC in humans remains to be intensively studied subjects. This review will provide up-to-date information regarding the recent outcomes of laboratory, epidemiology and/or clinical trials on the effects of vitamins on PC prevention and/or treatment.

    Full Text Available Background. Despite complete resection of gastrointestinal stromal tumors (GIST, recurrent and/or metastatic disease occurs, often depending on the grade of malignancy. As such, markers are needed that accurately predict patients at high risk for recurrence. Previously our group reported Pfetin as a prognostic biomarker for GIST. In order to create an approach for predicting risk of recurrence, we incorporated Pfetin expression with clinicopathological data to produce a predictive model. Object. Forty-five patients with localized primary GIST were treated with complete gross surgical resection surgically at our institution between 1995 and 2010 were included. The majority of tumors originated in the stomach (38 cases, as well as small intestine (6 cases and rectum (1 case. Method. (1 We performed retrospective analysis of the connection between Pfetin expression, clinicopathological data, and incidences of recurrence, using bivariate and multivariate analyses. (2 The reactivity of the monoclonal antibody against Pfetin was examined by immunohistochemistry. Pfetin. We have reported Pfetin, identified microarray technology, and compared between statistically different GISTs for good and poor prognoses and for prognostic marker. Results. There were 7 cases of recurrences. (1 By univariate analysis, tumor size, mitoses, exposure to abdominal cavity, and complete tumor removal predicted risk of recurrence. (2 Pfetin-negative cases were significantly related to recurrence (P = 0.002. Conclusions. This analysis demonstrates that lack of Pfetin expression is an additional predictor of recurrence in resected GIST. Further study may determine the role of this variable added to the current predictive model for selection of adjuvant therapy.

    S-1 plus cisplatin is the standard chemotherapy for recurrent gastric cancer. While depression and delirium are frequent in cancer patients, hypomania during chemotherapy is rare. We describe a rare case of hypomania during S-1 plus cisplatin treatment for recurrent gastric cancer. A 66-year-old woman, with no previous psychiatric disorder, received S-1 plus cisplatin for recurrent gastric cancer. She showed peculiar behavior. Physical examination, urine, blood and imaging findings were normal. There was no gastric cancer progression. During psychiatric consultation, she behaved inappropriately. However, she behaved normally while performing daily activities. She manifested a persistently elevated, expansive or irritable mood, clearly different from her usual non-depressed state, meeting hypomania diagnostic criteria. Her condition did not require chemotherapy discontinuation or additional medication. During the second and subsequent S-1 plus cisplatin cycles, symptoms were stable. Cancer patients often have adjustment disorders, depression and delirium, but rarely hypomania. Our patient showed no significant changes in blood biochemistry and brain and whole body imaging. While S-1 plus cisplatin-induced hypomania cannot be excluded, hypomanic symptoms did not improve during the chemotherapy rest period, nor was there deterioration during subsequent cycles, suggesting drug-induced mania to be unlikely. Possible onset mechanisms include manic defense phenomena, common with stressful life events. There are no reports of recurrent gastric cancer patients experiencing hypomania during S-1 or S-1 plus cisplatin therapy, i.e. our patient represents a rare course. Clinicians should recognize psychosis or mood disorders during gastric cancer treatment. Further accumulation of such rare cases might elucidate pathological mechanisms underlying hypomania in cancer patients.

    At present there is no oral medicine available which is effective for advanced or recurrent case of elderly patients with gynecologic cancer. We report that a low-dose biweekly paclitaxel administration preserves quality of life (QOL) and seems to be "tumor dormancy like" therapy of good compliance with few side effects. A total of 11 cases were in ovarian cancer (5), uterine cancer (3), cervical cancer (2), and uterine sarcoma (1). The median age was 68 years old and the age range was 50 to 79 years old. We performed a standard treatment as a first time treatment. Afterwards, we obtained complete informed consent from the patients for progressive or recurrent cancer and administered biweekly paclitaxel 70 mg/m2 (80-100 mg/body) on an outpatient basis. We reviewed the effect, side effect and compliance of the medication. We judged the side effect based on the Japanese cancer treatment society common toxicity criteria. The result was only one patient death from PD and the other 10 patients were PR or a state of NC without side effect. An ovary cancer case patient lived for 67 months at best, an endometrial cancer case patient lived for 62 months at best, a cervical cancer case patient lived for 74 months at best, and a recurrent uterine sarcoma case patient lived for 76 months after recurrence and the QOL was good. In addition, there was no onset of side effect more than grade 2 in all of the cases and a compliance of medical administration was good. In these cases, we thought that a low-dose of biweekly paclitaxel administration was regarded as a therapy to preserve QOL without a serious side effect and a good compliance of medication. Furthermore, we intend to increase more cases and would like to report them in the future. PMID:15918575

  18. Long-term oncologic results of salvage radical prostatectomy for locally recurrent prostate cancer after radiotherapy

    International Nuclear Information System (INIS)

    Purpose: Salvage radical prostatectomy (RP) may potentially cure patients who have isolated local prostate cancer recurrence after radiotherapy (RT). We report the long-term cancer control associated with salvage RP in a consecutive cohort of patients and identify the variables associated with disease progression and cancer survival. Methods and Materials: A total of 100 consecutive patients underwent salvage RP with curative intent for biopsy-confirmed, locally recurrent, prostate cancer after RT. Disease progression after salvage RP was defined as a prostate-specific antigen (PSA) level of ≥0.2 ng/mL or by initiation of androgen deprivation therapy. Cancer-specific mortality was defined as active clinical disease progression despite castration. Cox regression analysis was used to evaluate these endpoints. The median follow-up from RT was 10 years (range, 3-27 years) and from salvage RP was 5 years (range, 1-20 years). Results: Overall, the 5-year progression-free probability was 55% (95% confidence interval, 46-64%), and the median progression-free interval was 6.4 years. The preoperative PSA level was the only significant pretreatment predictor of disease progression in the multivariate analysis (p = 0.01). The 5-year progression-free probability for patients with a preoperative PSA level of 10 ng/mL was 86%, 55%, and 37%, respectively. The 10-year and 15-year cancer-specific mortality after salvage RP was 27% and 40%, respectively. The median time from disease progression to cancer-specific death was 10.3 years (95% confidence interval, 7.6-12.9). After multivariate analysis, the preoperative serum PSA level and seminal vesicle or lymph node status correlated independently with disease progression. Conclusions: Greater preoperative PSA levels are associated with disease progression and cancer-specific death. Long-term control of locally recurrent prostate cancer after definitive RT is possible when salvage RP is performed early in the course of recurrent

    Full Text Available Abstract Background The high frequency of local recurrence occurring after endoscopic piecemeal resection (EPMR for large colorectal tumors is a serious problem. However, almost all of these cases of local recurrence can be detected within 1 year and cured by additional endoscopic resection. We report a rare case of recurrent advanced colonic cancer diagnosed 11 years after initial EPMR treatment. Case presentation A 65-year-old male was diagnosed with a sigmoid colon lesion following a routine health check-up. Total colonoscopy revealed a 12 mm type 0-Is lesion in the sigmoid colon, which was diagnosed as an adenoma or intramucosal cancer and treated by EPMR in 1996. The post-resection defect was closed completely using metallic endoclips to avoid delayed bleeding. In 2007, at the third follow up, colonoscopy revealed a 20 mm submucosal tumor (SMT like recurrence at the site of the previous EPMR. The recurrent lesion was treated by laparoscopic assisted sigmoidectomy with lymph node dissection. Conclusion When it is difficult to evaluate the depth and margins of resected tumors following EPMR, it is important that the defect is not closed in order to avoid tumor implantation, missing residual lesions and to enable earlier detection of recurrence. It is crucial that the optimal follow-up protocol for EPMR cases is clarified, particularly how often and for how long they should be followed.

  1. Study Confirms Letrozole Prevents More Breast Cancer Recurrences than Tamoxifen

    To evaluate the correlations between aortic complex plaque (ACP) and the recurrence of cryptogenic ischemic cerebrovascular disease (CICVD), and to investigate the clinical significance of ACP in CICVD. Methods CICVD patients (aged 17 to 84 years) admitted into the Department of Neurology, Xuanwu Hospital, from July 2011 to December 2013, were consecutively recruited, and divided into ACP and non-ACP groups according to head and neck computerized tomographic (CT) angiography. Recurrences of cerebral ischemic events (CIEs) were compared between these groups after follow-up. Results A total of 117 patients were enrolled (ACP group: 69, non-ACP group: 48) and followed up for a mean of 9.86 months (range: 3-33). The average age of the ACP group was 62.88 years, with 59.4% older than 60 years; the average age of the non-ACP group was 50.29 years, with 37.5% older than 60 years. At the 6-month follow-up, the recurrence rate of CIEs in the ACP group was significantly higher than that of the non-ACP group (17.0% [7/47] and 0% [0/36], respectively; χ2 = 4.283, P = 0.046). The cumulative recurrence risk for CIEs of the ACP group was significantly higher than for the non-ACP group (P = 0.004). Multivariate Cox survival analysis showed that ACP presence was an independent risk factor for CIE recurrence for CICVD patients (relative risk [RR] = 7.803, 95% confidence interval [CI], 1.827~33.319, P = 0.006). Conclusions ACP increased the recurrence risk of CIE in CICVD, and elderly CICVD patients should receive greater attention regarding the significance of ACP in recurrent CICVD.

    Full Text Available Purpose. To evaluate the clinical outcome and risk factors for recurrent dislocation after arthroscopic stabilization with absorbable knotless anchor. Methods. We treated 197 patients affected by anterior shoulder instability, either traumatic or atraumatic with the same arthroscopic suture technique. We recorded age at surgery and number and type of dislocations (traumatic/atraumatic. Of the 197 patients, 127 (65.4% were examined with a mean follow-up of 5.6 years (range: 25–108 months. Eighty-one shoulders were evaluated with the Rowe score and 48 with the Simple Shoulder Test (SST. Results. The mean Rowe score was 90.8, while the mean SST score was 10.9. Recurrence occurred in 10 cases (7.7% but only in 4 cases was atraumatic, which reduces the real recurrence rate to 3.1%. Patients with recurrence were significantly younger at surgery than patients who did not relapse (P=0.040. Moreover, neither the number (P=0.798 nor the type of shoulder instability (P=0.751, or the amount of glenoid bone loss (P=0.184 significantly affected the probability of recurrence. Conclusions. In a patient population with involuntary monodirectional anterior shoulder instability, use of absorbable knotless anchor was reliable and resulted in a good outcome. In this series the statistical significant risk factors for recurrent dislocation were age of patient.

  4. Tumor recurrence and in-field control after multimodality treatment of locally advanced esophageal cancer

    International Nuclear Information System (INIS)

    Purpose: Neoadjuvant chemoradiotherapy is used prior to surgery in curative treatment of esophageal cancer (EC). We evaluated the in-field control of this multimodal treatment by extraction of radiation dose parameters and determination of the spatial relation between tumor recurrence location(s) and radiation target volume (RTV). Methods and materials: Treatment consisted of neoadjuvant chemotherapy (5-FU and cisplatin) and radiotherapy (36 Gy) followed by Ivor–Lewis esophagectomy. For patients with locoregional recurrence(s), image fusion was performed between radiotherapy planning CT and follow-up CT(s). A region-of-interest was contoured on the planning CT around each locoregional recurrence. Mean and maximum radiation doses were then extracted to classify recurrences as out-of-field, marginal or in-field. Results: Eighty patients were included. The median follow-up duration was 19 months. Fifteen of 95 locoregional recurrences were detected in the RTV. These in-field relapses occurred in only 6 patients (7.8%) on 12 different anatomical locations. None of the patients with in-field failure had a pCR and all had concurrent distant failure on multiple anatomical sites. Conclusion: Neoadjuvant chemoradiotherapy followed by Ivor–Lewis esophagectomy yields excellent in-field control, as only a clear minority (7.8%) of patients developed a relapse in the RTV. In-field recurrence is associated with widespread tumor dissemination and poor pathological response to neoadjuvant treatment

    To evaluate whether modified MUPIT applicator can effectively eradicate recurrent tumor in uterine cervix cancer and reduce rectal complication after complete radiation treatment. Modified MUPIT applicator basically consists of an acrylic cylinder with flexible brain applicator, an acrylic template with a predrilled array of holes that serve as guides for interstitial needles and interstitial needles. CT scan was performed to determine tumor volume and the position of interstitial needles. Modified MUPIT applicator was applied to patient in operation room and the accuracy for position of interstitial needles in tumor volume was confirmed by CT scan. Brachytherapy was delivered using modified MUPIT applicator and RALS(192-lr HDR) after calculated computer planning by orthogonal film. The daily dose was 600 cGy and the total dose was delivered 3,000 cGy in tumor volume by BID. Rectal dose was measured by TLD at 5 points so that evaluated the risk of rectal complication. The application of modified MUPIT applicator improved dramatically dose distributions in tumor volume and follow-up of 3 month for this patient was clinically partial response without normal tissue complication, Rectal dose was measured 34.1 cGy, 57.1 cGy, 103.8 cGy, 162.7 cGy, 165.7 cGy at each points, especially the rectal dose including previous EBRT and ICR was 34.1 cGy, 57.1 cGy. Patients with locally recurrent tumor in uterine cervix cancel treated with modified MUPIT applicator can expect reasonable rates of local control. The advantages of the system are the fixed geometry provided by the template and cylinders. and improved dose distributions in irregular tumor volume without rectal complication.

    Full Text Available Head and neck cancer recurrences after definitive radiotherapy present a difficult therapeutic problem, as only a small proportion of patients have resectable disease. When surgery is not possible, reirradiation might be a feasible option for selected patients, particularly those with favourable prognostic factors such as second primaries, nasopharyngeal or laryngeal tumours or delayed recurrences. Current evidence indicates that in this group of patients reirradiation offers better control rates than palliative chemotherapy. The loco regional control rates of reirradiation without surgery is 20% at five years and 27% at two years. The overall survival rate with reirradiation ranges from 10% to 35% at two years and 0% to 14.6% at five years. The first randomized trial directly comparing chemotherapy with reirradiation is in progress. This article outlines the indications for and results of reirradiation and chemotherapy in post radiotherapy recurrences of head and neck cancer.

    2009-12-01

    The objective was to establish whether the risk of trisomies 13, 18, and 21 (Patau, Edwards, and Down syndrome, respectively) in a subsequent pregnancy is raised for women who have had a previous pregnancy with trisomy 13, 18, or 21. Birth defect register data were used to investigate this issue. Pregnancy data from three Australian population-based birth defect registers contained 5,906 women with a previous trisomy 13, 18, or 21 pregnancy in whom there were 3,713 subsequent pregnancies, 75 of which were trisomic. Relative risk of subsequent trisomy at 15 weeks gestation was estimated by comparing the observed number of subsequent trisomies with the expected number of subsequent trisomies based on maternal age-related risk. There was evidence of increased risk of the same trisomy subsequent to a previous pregnancy with trisomy 13 or 18 (RR = 3.8 (1.5, 7.9)), the increase in risk being greater for women aged under 35 at the previous trisomic pregnancy (RR = 7.8 (2.1, 20.2)). There was also evidence of increased risk of trisomy 21 subsequent to previous trisomy 21 (RR = 2.2 (1.6, 2.9)), again higher in women under 35 at previous affected pregnancy (RR = 3.5 (2.1, 5.5)). There was a suggestion that the risk of a different trisomy subsequent to trisomy 21 may also be increased (RR = 1.4 (0.7, 2.5)). In conclusion, women who have had a previous trisomic pregnancy, particularly those under 35 years of age at the time, appear to be at an increased risk of future pregnancies being trisomic.

  9. Pre-operative FDG PET/CT findings related to early tumor recurrence in breast cancer patients

    International Nuclear Information System (INIS)

    The purpose of this study was to identify any pre-operative FDG PET/CT findings related to early recurrence in the breast cancer patients. One hundred eighteen breast cancer patients who underwent 18F-FDG PET/CT scan for preoperative staging from September 2004 to September 2005 were included. All patients received operation and follow-up examination. From the FDG PET/CT images, (1) the peak standard uptake values (pSUV) of the primary tumor, (2) pSUV of axillary lymph node (LN) were recorded. 7 out of 118 patients had tumor recurrence within 26 months after the surgery. The mean pSUV of primary tumors with early recurrence (6.113.22) was significantly higher than the mean pSUV of the early recurrence negative follow-up group (3.432.43). The mean pSUVs of the axillary LN showed no significant difference between the early recurrence group and recurrence negative (2.122.17 vs 2.411.13). Of 111 patients with no evidence of recurrence, 71 patients showed no perceptible FDG uptake in the axillary LNs. On the other hand, all of the 7 recurrent breast cancer cases show increased FDG uptakes of axillary LN. In the recurrence negative group, no axillary LN demonstrated perceptibly increased FDG uptakes in 64% (71/111 cases); increased FDG uptake was noted in 36% (40/111 cases). In breast cancer patients who had early recurrence, the pSUV of the primary tumor was significantly higher than that of early recurrence negative patients. Though the pSUV of the axillary LN was not a predictor of recurrent breast cancer, all recurrent breast cancer patients had FDG uptake in axillary LN

    Full Text Available Introduction: Urinary stone disease is a common urologic problem and recurrence in stone formation is a very familiar issue to urologists. Although recurrence in stone formation has been linked to metabolic abnormalities, it can be accessible by metabolic risk analysis studies.Methods: Herein, we present our experience in metabolic risk management on recurrence of urinary stones for 10 years in Akdeniz University School of Medicine department of Urology. We retrospectively analyzed Akdeniz University Urinary Stone Database between dates of January 2000 and December 2010. We found over 3500 patients who were managed by SWL (shock wave lithotripsy or PCNL (percutaneus nephrolithotripsy or URS (Ureterorenoscopic lithotripsy or open surgery.Results: 525 patients’ metabolic risk analysis was ordered due to recurrent urinary stone disease. Only 134 (25.5 % current metabolic analysis were returned. Mean patient age was 32.2 years (range: 19-82 years.Patients were 103 male and 31 female. Stone analysis results were CaOx monohydrate in 48 (35.8 %, CaOx dihydrate in 8 (5.9 %, CaOx mono and dihydrate in 70 (52.2 %, uric acid in 3, CaOx monohydrate and uricacid in 2, cystine in 2, and struvite in 1 patient, respectively. The  metabolic risk analysis showed some abnormality in 54 (40.2 % patients.Conclusion: Although compliance to metabolic risk analysis studies is low among recurrent urinary stone formers, some significant metabolic abnormalities could be detected in those who are effectively screened.Recurrence of urinary stones in patients who are started on appropriate metabolic management can be prevented.

  18. Predictive value of Sp1/Sp3/FLIP signature for prostate cancer recurrence.

    Directory of Open Access Journals (Sweden)

    Roble G Bedolla

    Full Text Available Prediction of prostate cancer prognosis is challenging and predictive biomarkers of recurrence remain elusive. Although prostate specific antigen (PSA has high sensitivity (90% at a PSA level of 4.0 ng/mL, its low specificity leads to many false positive results and considerable overtreatment of patients and its performance at lower ranges is poor. Given the histopathological and molecular heterogeneity of prostate cancer, we propose that a panel of markers will be a better tool than a single marker. We tested a panel of markers composed of the anti-apoptotic protein FLIP and its transcriptional regulators Sp1 and Sp3 using prostate tissues from 64 patients with recurrent and non-recurrent cancer who underwent radical prostatectomy as primary treatment for prostate cancer and were followed with PSA measurements for at least 5 years. Immunohistochemical staining for Sp1, Sp3, and FLIP was performed on these tissues and scored based on the proportion and intensity of staining. The predictive value of the FLIP/Sp1/Sp3 signature for clinical outcome (recurrence vs. non-recurrence was explored with logistic regression, and combinations of FLIP/Sp1/Sp3 and Gleason score were analyzed with a stepwise (backward and forward logistic model. The discrimination of the markers was identified by sensitivity-specificity analysis and the diagnostic value of FLIP/Sp1/Sp3 was determined using area under the curve (AUC for receiver operator characteristic curves. The AUCs for FLIP, Sp1, Sp3, and Gleason score for predicting PSA failure and non-failure were 0.71, 0.66, 0.68, and 0.76, respectively. However, this increased to 0.93 when combined. Thus, the "biomarker signature" of FLIP/Sp1/Sp3 combined with Gleason score predicted disease recurrence and stratified patients who are likely to benefit from more aggressive treatment.

    Ovarian cancer is the 5th most common cancer found in women in the UK. It is the leading cause of death from gynaecological cancer, and is the 4th most common cause of cancer death among UK women. Similar to the majority of other cancers, relative survival rates for ovarian cancer are improving, although 5-year mortality rates remain stubbornly low. The stage of the disease at diagnosis is the single most important determinant of ovarian cancer survival, as many patients first present with advanced disease. Treatment of ovarian cancer involves a combination of 'upfront' primary surgery followed by chemotherapy. Platinum/taxane-based chemotherapy is the recommended standard-of-care first-line chemotherapy, but the majority of patients will relapse with drug-resistant disease within 3-5 years. However, not all patients can continue with platinum combination therapies due to loss of activity or toxicity-related issues, including hypersensitivity, neurotoxicity, alopecia and ototoxicity. Therefore the choice of second-line chemotherapy must take into account factors such as platinum-free treatment interval (PFI); patient's performance status; current symptoms; history of and likely future toxicities while on chemotherapy; dosing schedule requirement; and cost of treatment. A consensus in 2010 established 4 distinct subgroups within the ROC patient population based on the PFI: (platinum sensitive <12 months, partially platinum sensitive 6-12 months, platinum resistant <6 months, and refractory disease ≤4 weeks). Within patients with platinum sensitive disease, those with partially platinum sensitive disease remain the most clinically challenging to manage effectively. Non-platinum based combination therapies, in particular trabectedin with pegylated liposomal doxorubicin (PLD), offers new options together with a significant survival advantage relative to PLD alone for these patients.

Although most patients respond well to discontinuation of antibiotics, 20%–30% of patients relapse. To initiate early therapeutic measures, the risk factors for recurrent CDI must be identified, although very few Japanese studies have used standard surveillance definitions to identify these risk factors.Methods: We retrospectively reviewed the medical records of patients with health care facility-onset CDI between August 2011 and September 2013. Patients with diarrhea who were positive for Clostridium difficile (via an enzyme immunoassay were defined as having CDI. Clinical data (eg, demographics, comorbidities, medication, laboratory results, and clinical outcomes were evaluated, and multivariate analysis was used to identify risk factors that were associated with recurrent CDI.Results: Seventy-six health care facility-onset CDI cases were identified, with an incidence rate of 0.8 cases per 10,000 patient-days. Fourteen cases (18.4% were recurrent, with 13 patients having experienced a single recurrent episode and one patient having experienced three recurrent episodes. The 30-day and 90-day mortality rates were 7.9% and 14.5%, respectively. Multivariate analysis revealed that recurrent patients were more likely to have underlying malignant disease (odds ratio: 7.98; 95% confidence interval: 1.22–52.2; P=0.03 and a history of intensive care unit hospitalization (odds ratio: 49.9; 95% confidence interval: 1.01–2,470; P=0.049.Conclusion: Intensive care unit hospitalization and malignancy are risk factors for recurrent

    Full Text Available Background: Approximately 2-4% of all women have recurrent spontaneous abortion (RSA; however, the cause is determined in only 50% of cases. Recent studies have shown an association between thyroid autoantibodies as a sign of thyroid autoimmunity and abortion. The aim of the present study was to determine whether circulating anti-thyroid peroxidase (anti-TPO was associated with RSA.Materials and Methods: In this observational analytic study, Sera from 58 non-pregnant women with a history of RSA and also 58 healthy, fertile subjects with at least one live birth as control (Aging from 18 to 45 years were tested for thyroid peroxidase antibodies by means of a standard Anti-TPO ELISA kit. We used data collection forms and SPSS software for data analysis.Results: Of 116 women, 8 (13.8% of the control subjects and 12 (20.7% of the women with a history of RSA had positive results for anti-TPO. There was not any significant association between presence of anti-TPO and RSA.Conclusions: We did not find any correlation between the presence of TPO antibodies and abortion in women with a history of RSA. On the basis of this study, testing for anti-TPO doesn’t seem to be useful in the evaluation of patients with a history of RSA.

    Full Text Available Abstract Background In the course of surveillance of gastric cancer recurrence after curative resection, contrast CT scan is used in general. However, new findings from CT scan are not always confirmatory for the recurrence. In this case, we usually use short-term follow up strategy or therapeutic intervention with clinical decision. Recently, the use of fusion Positron Emission Tomography/Computed Tomography (PET/CT is increasing. The purpose of this study is to evaluate the efficacy and usefulness of PET/CT for detecting recurrence of gastric cancer after curative resection. Methods Fifty two patients who received curative resection of gastric cancer and had undergone PET/CT and contrast CT for surveillance of recurrence until Dec 2006 in Seoul National University Hospital were analyzed retrospectively. Recurrence of gastric cancer was validated by histologic confirmation (n = 17 or serial contrast CT follow up with at least 5 month interval (n = 35. McNemar's test and Fisher's exact test were used to evaluate sensitivity and specificity of PET/CT and contrast CT. Results Of 52 patients, 38 patients were confirmed as recurrence. The sensitivity was 68.4% (26/38 for PET/CT and 89.4% (34/38 for contrast CT (p = 0.057. The specificity was 71.4% (10/14 and 64.2% (9/14, respectively (p = 1.0. In terms of the recurred sites, the sensitivity and specificity of PET/CT were similar to those of contrast CT in all sites except peritoneum. Contrast CT was more sensitive than PET/CT (p = 0.039 for detecting peritoneal seeding. Additional PET/CT on contrast CT showed no further increase of positive predictive value regardless of sites. Among 13 patients whose image findings between two methods were discordant and tissue confirmation was difficult, the treatment decision was made in 7 patients based on PET/CT, showing the final diagnostic accuracy of 42.8% (3/7.

    We evaluated whether the maximum standardized uptake values (SUV{sub max}) of primary tumor from the initial staging by {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) of patients with breast cancer could identify patients at risk for early recurrence within 2 years, particularly in comparison to the American Joint Committee on Cancer (AJCC) stage. We reviewed the staging {sup 18}F-FDG PET/CT images of patients with primary breast cancer and their medical records. The SUV{sub max} of the primary tumor was measured. The presence or absence of FDG uptake in the axillary lymph node (ALN) was also assessed. The patient's pathologic primary tumor stage (pT), pathologic regional lymph node stage (pN), stage grouping, age, estrogen receptor (ER) and progesterone receptor (PR) status, and neoadjuvant chemotherapy history were evaluated with the FDG uptake parameters for recurrence within 2 years following the end of first-line therapy. Recurrence within 2 years was present in 9.1%(n =40) out of the 441 patients assessed. The FDG uptake in ALN, pT, pN, stage grouping and neoadjuvant chemotherapy history were prognostic for early recurrence, while primary tumor SUV{sub max}, age, and ER or PR status were not significant on logistic regression. On multivariate analysis, only the stage grouping (odds ratio 2.79; 95 % CI 1.73, 4.48; p <0.0001) and neoadjuvant chemotherapy history (odds ratio 2.70; 95 % CI 1.22, 5.98; p =0.0141) could identify patients at increased risk for recurrence within 2 years. Primary tumor FDG uptake measured by SUV{sub max}, and visual assessment of FDG uptake in the ALN in the initial staging PET/CT of patients with breast cancer may not have additional prognostic value compared with the AJCC stage grouping for early recurrence.

  5. Recurrence patterns of thoracic esophageal cancer after two-field lymph node dissection

    International Nuclear Information System (INIS)

    Objective: To investigate the local-regional recurrence in thoracic esophageal cancer after radical surgery including two-field lymph node dissection and provide evidence for postoperative radiotherapy. Methods: We reviewed local-regional recurrence for 134 cases with esophageal squamous cell carcinoma after radical surgery from 2004 to 2009. Results: In 134 cases, lymph node metastasis rate,anastomosis recurrence rate and tumor bed recurrence rate was 94. 0%, 9. 7% and 3.7%, respectively. As to the 126 cases with lymph node metastasis, significant difference was detected between mediastinal metastasis, supraclavicular metastasis and abdominal lymph node metastasis (80.2%, 43.7% and 13.5%, respectively, χ2= 113.15, P = 0.000). Furthermore, the relative metastasis rate in upper mediastinum,middle mediastinum and the lower mediastinum was 73.8%, 39.7% and 1.6%, respectively, the difference was statistically significant (χ2 = 139.11, P = 0.000). Significant difference was identified between right and left supraclavicular lymph node metastasis (31.7% vs 16.7%, χ2= 7. 81, P = 0.005). To confirm the analysis above, lymph node metastasis rate of left recurrent laryngeal nerve nodes, (including region 1L, 2L, 4L and 5) ,right recurrent laryngeal nerve nodes, azygos nodes, subcarinal nodes, and 2R region was 38.9%, 43.7%, 15.1%, 34.1% and 25.4%, respectively. Conclusions: The main characteristics of local-regional recurrence may be lymph node metastasis for esophageal squamous cell carcinoma after radical surgery. On the contrary, tumor bed recurrence is rare. Dangerous regions include supraclavicular nodes, recurrent laryngeal nerve nodes, azygos nodes as well as subcarinal nodes. (authors)

    Whilst common genetic variation in many non-coding genomic regulatory regions are known to impart risk of colorectal cancer (CRC), much of the heritability of CRC remains unexplained. To examine the role of recurrent coding sequence variation in CRC aetiology, we genotyped 12,638 CRCs cases and 29,045 controls from six European populations. Single-variant analysis identified a coding variant (rs3184504) in SH2B3 (12q24) associated with CRC risk (OR = 1.08, P = 3.9 × 10−7), and novel damaging coding variants in 3 genes previously tagged by GWAS efforts; rs16888728 (8q24) in UTP23 (OR = 1.15, P = 1.4 × 10−7); rs6580742 and rs12303082 (12q13) in FAM186A (OR = 1.11, P = 1.2 × 10−7 and OR = 1.09, P = 7.4 × 10−8); rs1129406 (12q13) in ATF1 (OR = 1.11, P = 8.3 × 10−9), all reaching exome-wide significance levels. Gene based tests identified associations between CRC and PCDHGA genes (P < 2.90 × 10−6). We found an excess of rare, damaging variants in base-excision (P = 2.4 × 10−4) and DNA mismatch repair genes (P = 6.1 × 10−4) consistent with a recessive mode of inheritance. This study comprehensively explores the contribution of coding sequence variation to CRC risk, identifying associations with coding variation in 4 genes and PCDHG gene cluster and several candidate recessive alleles. However, these findings suggest that recurrent, low-frequency coding variants account for a minority of the unexplained heritability of CRC. PMID:26553438

  11. Risk of second primary cancer following differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Concerns remain over the risk of cancer following differentiated thyroid carcinoma and its causes. Iodine-131 (131I) and external irradiation are known to have potential carcinogenic effects. Thyroid carcinoma is a polygenic disease which may be associated with other malignancies. We investigated the incidence of second cancer and its aetiology in a cohort of 875 patients (146 men, 729 women) with differentiated thyroid carcinoma originating from Basse-Normandie, France. Cancer incidence was compared with that of the general population of the Departement du Calvados matched for age, gender and period. The cumulative proportion of second cancer was estimated using the life-table method. Factors that correlated with the risk of second cancer were studied using the Cox model. After a median follow-up of 8 years, 58 second cancers had been observed. Compared with general population incidence rates, there was an overall increased risk of second cancer in women [standardised incidence ratio (SIR)=1.52; P0.20). Increased risk related to cancers of the genitourinary tract (SIR=3.31; P131I was related to the risk. These data confirm that women with differentiated thyroid carcinoma are at risk of developing a second cancer of the genitourinary tract and kidney. Only age and medical history of primary cancer before thyroid carcinoma are risk factors for second cancer. Common environmental or genetic factors as well as long-term carcinogenic effects of primary cancer therapy should be considered. (orig.)

    An assessment of the risk of future volcanism has been conducted for isolation of high-level radioactive waste at the potential Yucca Mountain site in southern Nevada. Risk used in this context refers to a combined assessment of the probability and consequences of future volcanic activity. Past studies established bounds on the probability of magmatic disruption of a repository. These bounds were revised as additional data were gathered from site characterization studies. The probability of direct intersection of a potential repository located in an eight km{sup 2} area of Yucca Mountain by ascending basalt magma was bounded by the range of 10{sup {minus}8} to 10{sup {minus}10} yr{sup {minus}1 2}. The consequences of magmatic disruption of a repository were estimated in previous studies to be limited. The exact releases from such an event are dependent on the strike of an intruding basalt dike relative to the repository geometry, the timing of the basaltic event relative to the age of the radioactive waste and the mechanisms of release and dispersal of the waste radionuclides in the accessible environment. The combined low probability of repository disruption and the limited releases associated with this event established the basis for the judgement that the risk of future volcanism was relatively low. It was reasoned that that risk of future volcanism was not likely to result in disqualification of the potential Yucca Mountain site.

  14. Expression of tumor necrosis factor-alpha-mediated genes predicts recurrence-free survival in lung cancer.

    Directory of Open Access Journals (Sweden)

    Baohua Wang

    Full Text Available In this study, we conducted a meta-analysis on high-throughput gene expression data to identify TNF-α-mediated genes implicated in lung cancer. We first investigated the gene expression profiles of two independent TNF-α/TNFR KO murine models. The EGF receptor signaling pathway was the top pathway associated with genes mediated by TNF-α. After matching the TNF-α-mediated mouse genes to their human orthologs, we compared the expression patterns of the TNF-α-mediated genes in normal and tumor lung tissues obtained from humans. Based on the TNF-α-mediated genes that were dysregulated in lung tumors, we developed a prognostic gene signature that effectively predicted recurrence-free survival in lung cancer in two validation cohorts. Resampling tests suggested that the prognostic power of the gene signature was not by chance, and multivariate analysis suggested that this gene signature was independent of the traditional clinical factors and enhanced the identification of lung cancer patients at greater risk for recurrence.

  16. Rib fractures after reirradiation plus hyperthermia for recurrent breast cancer. Predictive factors

    International Nuclear Information System (INIS)

    Combining reirradiation (reRT) and hyperthermia (HT) has shown high therapeutic value for patients with locoregional recurrent breast cancer (LR). However, additional toxicity of reirradiation (e.g., rib fractures) may occur. The aim of this study is to determine the impact of potential risk factors on the occurrence of rib fractures. From 1982-2005, 234 patients were treated with adjuvant reRT + HT after surgery for LR. ReRT consisted typically of 8 fractions of 4 Gy twice a week, or 12 fractions of 3 Gy four times a week. A total of 118 patients were irradiated with abutted photon and electron fields. In all, 60 patients were irradiated using either one or alternating combinations of abutted AP electron fields. Hyperthermia was given once or twice a week. The 5-year infield local control (LC) rate was 70 %. Rib fractures were detected in 16 of 234 patients (actuarial risk: 7 % at 5 years). All rib fractures occurred in patients treated with a combination of photon and abutted electron fields (p = 0.000); in 15 of 16 patients fractures were located in the abutment regions. The other significant predictive factors for rib fractures were a higher fraction dose (p = 0.040), large RT fields, and treatment before the year 2000. ReRT + HT results in long-term LC. The majority of rib fractures were located in the photon/electron abutment area, emphasizing the disadvantage of field overlap. Large abutted photon/electron fields combined with 4 Gy fractions increase the number of rib fractures in this study group. However, as these factors were highly correlated no relative importance of the individual factors could be estimated. Increasing the number of HT sessions a week does not increase the risk of rib fractures. (orig.)

    Purpose: Although positive surgical margins are generally associated with a higher risk of local-regional recurrence (LRR) for most solid tumors, their significance after mastectomy remains unclear. We sought to clarify the influence of the mastectomy margin on the risk of LRR. Methods and Materials: The retrospective cohort consisted of 397 women who underwent mastectomy and no radiation for newly diagnosed invasive breast cancer from 1998-2005. Time to isolated LRR and time to distant metastasis (DM) were evaluated by use of cumulative-incidence analysis and competing-risks regression analysis. DM was considered a competing event for analysis of isolated LRR. Results: The median follow-up was 6.7 years (range, 0.5-12.8 years). The superficial margin was positive in 41 patients (10%) and close ({<=}2 mm) in 56 (14%). The deep margin was positive in 23 patients (6%) and close in 34 (9%). The 5-year LRR and DM rates for all patients were 2.4% (95% confidence interval, 0.9-4.0) and 3.5% (95% confidence interval, 1.6-5.3) respectively. Fourteen patients had an LRR. Margin status was significantly associated with time to isolated LRR (P=.04); patients with positive margins had a 5-year LRR of 6.2%, whereas patients with close margins and negative margins had 5-year LRRs of 1.5% and 1.9%, respectively. On univariate analysis, positive margins, positive nodes, lymphovascular invasion, grade 3 histology, and triple-negative subtype were associated with significantly higher rates of LRR. When these factors were included in a multivariate analysis, only positive margins and triple-negative subtype were associated with the risk of LRR. Conclusions: Patients with positive mastectomy margins had a significantly higher rate of LRR than those with a close or negative margin. However, the absolute risk of LRR in patients with a positive surgical margin in this series was low, and therefore the benefit of postmastectomy radiation in this population with otherwise favorable

  19. Outcome following radiotherapy for loco-regionally recurrent non-small cell lung cancer

    International Nuclear Information System (INIS)

    Local and regional recurrence of non-small cell lung cancer is reported to occur in 13-20% of treatment failures after resection. Reported post-recurrent median survival following radiotherapy ranges from 9 to 14 months. This study examines survival following radiotherapy alone for patients with loco-regionally recurring non-small cell lung cancer after initial surgery. Fifty-five patients, receiving radiotherapy at Westmead Hospital between 1979 and 1997, were eligible for study. Data were collected retrospectively by reviewing patient records. The end-point was overall survival. Symptom control was also recorded. Prognostic factors for analysis included age, sex, original presenting stage, disease-free interval (DFI), performance status, site of recurrence, treatment intent and dose. The median overall survival was 11.5 months (95% confidence interval: 8.1-13.0). Survival following treatment with radical intent was 26 months compared to 10.5 months for patients treated with palliative intent (P = 0.025). There was no significant difference in survival for short (<2 years) or long DFI, performance status, radiation dose, age, sex, site of recurrence or stage. Most patients (55%) had partial or complete resolution of symptoms. Radiotherapy results in overall post-recurrence median survival of nearly 1 year, consistent with previous published data. Radical treatment intent predicts better prognosis as a result of patient selection and higher dose. Radiotherapy is effective at palliating symptoms of this disease Copyright (2005) Blackwell Publishing Asia Pty Ltd

    It is currently estimated that about 0.5% of patients will develop Kaposi's sarcoma (KS) after kidney transplantation. Tapering of immunosuppression often leads to KS remission, but also results in graft loss in more than 50% of cases. Whether retransplantation is safe in these patients is unknown. We here report on eight patients who developed KS recurrence after kidney transplantation-(A) Patients with previously treated KS: There were 4 patients who had clinical remission of KS (including three posttransplantation) for periods ranging from 5 months up to 19 years before transplantation. All 4 developed KS recurrence within months after transplantation. In 3 patients, KS regressed only when all immunosuppression was discontinued, at the price of allograft removal. Partial remission occurred in the fourth patient following reduction of immunosuppression and gancyclovir administration; (B) Patients with recurrent KS during a single transplant: 4 patients developed KS after transplantation that regressed following reduction of immunosuppressive therapy. Increased immunosuppression, in the form of steroid pulses in 3 patients was associated with recurrence of KS. Subsequent reduction of immunosuppression caused regression of KS in all 4 patients, but 2 recipients lost their allografts. These data emphasize the high risk of recurrence of KS after renal transplantation. If physicians decide to transplant patients with a history of KS, they should inform the future recipient of the possibility of KS recurrence. PMID:8781611

    Human vaccines against infectious agents are often effective in a prophylactic setting. However, they are usually not effective when used post-exposure. Rabies vaccine is one of the exceptions, which can be used post-exposure, but is effective only when used in combination with other treatments. Similar results have been obtained with cancer vaccines and immunotherapies. Cancer immunotherapies generally prolong patients' survival when they are used during advanced stage disease. The potential of immunotherapy to cure cancer could be revealed when it is applied in a prophylactic setting. This article provides a brief overview of cancer immunotherapeutics and suggests that immunotherapy can cure cancer if used at the right time against the right target; we suggest that targeting cancer during dormancy in order to prevent tumor recurrence as advanced stage disease is potentially curative.

  4. Survival analysis of colorectal cancer patients with tumor recurrence using global score test methodology

    International Nuclear Information System (INIS)

    Colorectal cancer is the third and the second most common cancer worldwide in men and women respectively, and the second in Malaysia for both genders. Surgery, chemotherapy and radiotherapy are among the options available for treatment of patients with colorectal cancer. In clinical trials, the main purpose is often to compare efficacy between experimental and control treatments. Treatment comparisons often involve several responses or endpoints, and this situation complicates the analysis. In the case of colorectal cancer, sets of responses concerned with survival times include: times from tumor removal until the first, the second and the third tumor recurrences, and time to death. For a patient, the time to recurrence is correlated to the overall survival. In this study, global score test methodology is used in combining the univariate score statistics for comparing treatments with respect to each survival endpoint into a single statistic. The data of tumor recurrence and overall survival of colorectal cancer patients are taken from a Malaysian hospital. The results are found to be similar to those computed using the established Wei, Lin and Weissfeld method. Key factors such as ethnic, gender, age and stage at diagnose are also reported

    AIM: To evaluate the diagnostic accuracy, sensitivity,specificity of contrast-enhanced computed tomographic colonography in detecting local recurrence of colorectal cancer.METHODS: From January 2000 to December 2004,434 patients after potentially curative resection for invasive colorectal cancer were followed up for a period ranging from 20 to 55 mo. Eighty of the four hundred and thirty-four patients showing strong clinical evidence for recurring colorectal cancer during the last followup were enrolled in this study. Each patient underwent contrast-enhanced computed tomographic colonography and colonoscopy on the same day. Any lesions, biopsies,identified during the colonoscopic examination, immediate complications and the duration of the procedure were recorded. The results of contrast-enhanced computed tomographic colonography were evaluated by comparing to those of colonoscopy, surgical finding, and clinical follow-up.RESULTS: Contrast-enhanced computed tomographic colonography had a sensitivity of 100%, a specificity of 83% and an overall accuracy of 94% in detecting local recurrent colorectal cancer.CONCLUSION: Conventional colonoscopy and contrastenhanced tomographic colonography can complement each other in detecting local recurrence of colorectal cancer.

    The standard treatment for metastatic pancreatic cancer is chemotherapy. The effect of surgical resection for localized recurrence in the remnant pancreas after pancreatectomy for pancreatic cancer is unknown, but is reported to have a moderately good outcome in a few reports. We herein report a case of curative resection for recurrence in the remnant pancreas, 24 months after distal pancreatectomy for pancreatic cancer. A 71-year-old man was diagnosed with pancreas tail cancer. Neoadjuvant treatment with chemoradiotherapy[ weekly full-dose gemcitabine(GEM) and radiation therapy 50 Gy/25 Fr] was followed by distal pancreatectomy. Postoperative adjuvant therapy with hepatic arterial infusion of 5-FU and systemic GEM therapy was completed. Twenty-four months after surgery, follow-up computed tomography scan results showed a lesion of 15-mm diameter in the remnant pancreas. Resection of the remnant pancreas was performed. The pathological findings showed moderately differentiated adenocarcinoma, morphologically similar to the primary pancreatic cancer. Six months following surgery, there are no signs of recurrence at present.

    Colorectal cancer is the third and the second most common cancer worldwide in men and women respectively, and the second in Malaysia for both genders. Surgery, chemotherapy and radiotherapy are among the options available for treatment of patients with colorectal cancer. In clinical trials, the main purpose is often to compare efficacy between experimental and control treatments. Treatment comparisons often involve several responses or endpoints, and this situation complicates the analysis. In the case of colorectal cancer, sets of responses concerned with survival times include: times from tumor removal until the first, the second and the third tumor recurrences, and time to death. For a patient, the time to recurrence is correlated to the overall survival. In this study, global score test methodology is used in combining the univariate score statistics for comparing treatments with respect to each survival endpoint into a single statistic. The data of tumor recurrence and overall survival of colorectal cancer patients are taken from a Malaysian hospital. The results are found to be similar to those computed using the established Wei, Lin and Weissfeld method. Key factors such as ethnic, gender, age and stage at diagnose are also reported.

    OBJECTIVE To identify clinicopathological characteristics as predictive factors for recurrence in early gastric cancer (EGC), and to determine which lesions should be removed by gastrectomy by means other than endoscopic mucosal resection (EMR).METHODS Data from 249 patients with EGC were collected and the relationship between their clinicopathological characteristics and postoperative recurrence was retrospectively analyzed by univariate analysis.RESULTS Of the 249 patients after gastrectomy, 19 cases (7.6%)experienced a recurrence. The postoperative recurrence rate was 18.9%(7/37) in patients with lymph node metastasis, and 5.7%(12/212) in those without. Lymph node metastases were found to be significantly related to recurrence in EGC (P = 0.005).CONCLUSION Lymph node metastases were the only predictive factor for recurrence in EGC. However, this was not the determining factor for performing gastrectomy rather than EMR. Although after gastrectomy with lymphadenectomy of EGC, patients with lymph node metastasis should be considered as candidates for adjuvant treatment. For lymph-node metastatic EGCs, adjuvant therapy is recommended following gastrectomy with lymphadenectomy.

    Purpose A telomerase reverse transcriptase (TERT) promoter mutation was identified in thyroid cancer. This TERT promoter mutation is thought to be a prognostic molecular marker, because its association with tumor aggressiveness, persistence/recurrence, and disease-specific mortality in papillary thyroid carcinoma (PTC) has been reported. In this study, we attempted to determine whether the impact of the TERT promoter mutation on PTC persistence/recurrence is independent of clinicopathological parameters. Materials and Methods Using propensity score matching, 39 patients with PTC persistence or recurrence were matched with 35 patients without persistence or recurrence, with a similar age, sex, tumor size, multifocality, bilaterality, extrathyroidal extension, and lymph node metastasis. The TERT promoter and the BRAF V600E mutations were identified from PTC samples. Results The TERT promoter mutation was detected in 18% of PTC patients (13/74). No significant difference in the frequency of the TERT promoter mutation was observed between the persistence/recurrence group and the non-recurrence group. Conclusion These results suggest that the prognostic implications of the TERT promoter mutation are dependent on clinicopathological parameters. PMID:26727717

    Full Text Available Currently the diagnosis of local recurrence of prostate cancer (PCa after radical prostatectomy (RT is based on the onset of biochemical failure which is defined by two consecutive values of prostate-specific antigen (PSA higher than 0.2 ng/mL. The aim of this paper was to review the current roles of advanced imaging in the detection of locoregional recurrence. A nonsystematic literature search using the Medline and Cochrane Library databases was performed up to November 2013. Bibliographies of retrieved and review articles were also examined. Only those articles reporting complete data with clinical relevance for the present review were selected. This review article is divided into two major parts: the first one considers the role of PET/CT in the restaging of PCa after RP; the second part is intended to provide the impact of multiparametric-MRI (mp-MRI in the depiction of locoregional recurrence. Published data indicate an emerging role for mp-MRI in the depiction of locoregional recurrence, while the performance of PET/CT still remains unclear. Moreover Mp-MRI, thanks to functional techniques, allows to distinguish between residual glandular healthy tissue, scar/fibrotic tissue, granulation tissue, and tumour recurrence and it may also be able to assess the aggressiveness of nodule recurrence.

  14. Concurrent radiotherapy and taxane chemotherapy in patients with locoregional recurrence of breast cancer. A retrospective analysis

    International Nuclear Information System (INIS)

    Background and purpose: locoregional breast cancer recurrence is characterized by a high rate of systemic and local re-recurrence. Data on concurrent radiochemotherapy (RCT) in these cases are scarce. The purpose of this study was to evaluate feasibility, toxicity and efficacy of local control of a radiotherapy combined with a chemotherapy containing a taxane. Patients and methods: between May 1999 and November 2004, 36 women referred to the authors' clinic because of locoregional breast cancer recurrence that was either inoperable (n = 29) or resected (n = 7) received concurrent irradiation and taxane monotherapy weekly (TAX/RT; n = 28: paclitaxel 90 mg/m2 n = 24, or docetaxel 35 mg/m2, n = 4) or taxane + cisplatin therapy (TAX/CIS/RT; n = 8; paclitaxel 135 mg/m2 d1 and cisplatin 20 mq/m2 d1-5 q28). Results: comparing TAX/RT with TAX/CIS/RT, the complete remission rate in patients with macroscopic tumor prior to RCT was significantly higher for TAX/RT than for TAX/CIS/RT (7/19 vs. 0/8; p = 0.046), but overall remission rates were comparable, i.e., partial remission: 11/20 versus 6/8 cases, stable disease (no change): 1/20 versus 2/8 cases, and response rate: 95% versus 75%, respectively. The cumulative local recurrence-free survival rate at 1 and 2 years post-treatment was 83% and 68% and that of systemic recurrence-free survival 56% and 29%, respectively. The main toxic reactions of third-degree and higher were dermatitis in TAX/RT (57% vs. 11% for TAX/CIS/RT) and leukocytopenia in TAX/CIS/RT (62% vs. 7% for TAX/RT). Conclusion: concurrent irradiation and taxane chemotherapy weekly, in particular with paclitaxel, is recommended due to response and acceptable side effects for treatment of inoperable locoregional breast cancer recurrence.

    New human mutations are thought to originate in germ cells, thus making a recurrence of the same mutation in a sibling exceedingly rare. However, increasing sensitivity of genomic technologies has anecdotally revealed mosaicism for mutations in somatic tissues of apparently healthy parents. Such somatically mosaic parents might also have germline mosaicism that can potentially cause unexpected intergenerational recurrences. Here, we show that somatic mosaicism for transmitted mutations among parents of children with simplex genetic disease is more common than currently appreciated. Using the sensitivity of individual-specific breakpoint PCR, we prospectively screened 100 families with children affected by genomic disorders due to rare deletion copy-number variants (CNVs) determined to be de novo by clinical analysis of parental DNA. Surprisingly, we identified four cases of low-level somatic mosaicism for the transmitted CNV in DNA isolated from parental blood. Integrated probabilistic modeling of gametogenesis developed in response to our observations predicts that mutations in parental blood increase recurrence risk substantially more than parental mutations confined to the germline. Moreover, despite the fact that maternally transmitted mutations are the minority of alleles, our model suggests that sexual dimorphisms in gametogenesis result in a greater proportion of somatically mosaic transmitting mothers who are thus at increased risk of recurrence. Therefore, somatic mosaicism together with sexual differences in gametogenesis might explain a considerable fraction of unexpected recurrences of X-linked recessive disease. Overall, our results underscore an important role for somatic mosaicism and mitotic replicative mutational mechanisms in transmission genetics.

    Brachytherapy targeted to the peripheral zone with magnetic resonance imaging (MRI) guidance is a prostate cancer treatment option with potentially fewer complications than other treatments. Follow-up MRI when failure is suspected is, however, difficult because of radiation-induced changes. Furthermore, MR spectroscopy (MRS) is compromised by susceptibility artifacts from radioactive seeds in the peripheral zone. We report a case in which combined MRI/MRS was useful for the detection of prostate cancer in the transitional zone in patients previously treated with MR-guided brachytherapy. We propose that MRI/MRS can help detect recurrent prostate cancer, guide prostate biopsy, and help manage salvage treatment decisions. PMID:16360468

    The purpose of this study is to evaluate the relationship between TOP2A RNA expression and recurrence in patients with operable estrogen receptor (ER) positive breast cancer. We evaluated TOP2A expression in a pooled analysis of 4 independent data sets with gene expression data including 752 patients with early stage, ER-positive, HER2-negative breast cancer, most of whom received either no adjuvant therapy or endocrine therapy without chemotherapy. We also used an algorithm to simulate the Oncotype DX Recurrence Score (simRS) and the proliferation component of the Recurrence Score (simPS). Results are expressed as the hazard ratio (HR) for estimates of the effect of a one standard deviation increase in the value of the log gene expression (x + 1SD vs. x) as a continuous function. TOP2A expression was significantly associated with recurrence (HR 1.56, pcancer, a population known to have low incidence of TOP2A gene alterations. These findings confirm prior reports indicating that TOP2A expression provides prognostic information in ER-positive breast cancer. TOP2A expression may also be useful for identifying those with an intermediate RS who are more likely to relapse, although additional validation in datasets including measured rather than simulated RS will be required.

  20. Decision logic for retreatment of asymptomatic lung cancer recurrence based on positron emission tomography findings

    International Nuclear Information System (INIS)

    Purpose: The purpose of the study was to determine if Positron emission tomography (PET) 2-[F-18] fluoro-2-deoxy-D-glucose (FDG) imaging could detect subclinical local lung cancer recurrence and whether retreatment of such recurrence was feasible and beneficial. Methods and Materials: Twenty patients with biopsy proven lung cancer were studied with Positron emission tomography for the purpose of detecting subclinical lung cancer recurrence over a period of 4.25 years. All patients were treated with external radiation as part or all of their therapy. Twenty patients had baseline PET and computed tomography (CT) studies for comparison with later studies. Surviving patients had a total of 40 sequential PET scans and 35 CT scans. The follow-up interval ranged from 5 to 40 months posttreatment. The differential uptake ratio (DUR) was determined for regions of interest of increased FDG uptake. Results: The median DUR value of the 20 baseline PET studies was 5.59. The DUR value of greater than 3 was empirically selected as being positive for tumor detection. On baseline studies, PET had a 100% correlation with the CT findings in regard to detection of the site of primary tumor involvement. Four of 20 patients showed areas of discordance in the mediastinal and hilar areas on initial PET and CT studies. Seven of 17 patients showed discordant posttreatment PET-CT findings. Two false positive PET studies were due to radiation pneumonitis and one to macrophage glycolysis in tumor necrosis. For detection of asymptomatic tumor recurrence, analysis of sequential PET and CT studies, biopsy results, and the patient's clinical course suggested that PET had a sensitivity of 100%, specificity of 89.3%, and accuracy of 92.5%. Computerized Tomography was found to have a sensitivity of 67%, specificity of 85%, and accuracy of 82% for detection of such early-stage recurrence. Five patients went on to have retreatment with external irradiation based upon the PET evidence. Four retreated

    Full Text Available Background. The optimal use of urine markers in the surveillance of non-muscle-invasive bladder cancer (NMIBC remains unclear. Aim of the present study was to investigate the combined and stepwise use of the four most broadly available urine markers to detect tumor recurrence in patients undergoing surveillance of NMIBC. Patients and Methods. 483 patients with history of NMIBC were included. Cytology, UroVysion, fluorescence in situ hybridization (FISH, immunocytology (uCyt+, and NMP22 ELISA were performed before surveillance cystoscopy. Characteristics of single tests and combinations were assessed by contingency analysis. Results. 128 (26.5% patients had evidence of tumor recurrence. Sensitivities and negative predictive values (NPVs of the single tests ranged between 66.4–74.3 and 82.3–88.2%. Two-marker combinations showed sensitivities and NPVs of 80.5–89.8 and 89.5–91.2%. A stepwise application of the two-test combinations with highest accuracy (cytology and FISH; cytology and uCyt+; uCyt+ and FISH showed NPVs for high-risk recurrences (G3/Cis/pT1 of 98.8, 98.8, and 99.1%, respectively. Conclusions. Combinations of cytology, FISH, immunocytology, and NMP22 show remarkable detection rates for recurrent NMIBC. Stepwise two-test combinations of cytology, FISH, and immunocytology have a low probability of missing a high-risk tumor. The high sensitivities may justify the use of these combinations in prospective studies assessing the use of urine markers to individualize intervals between cystoscopies during follow-up.

  2. To identify the factors affecting the risk of recurrent febrile seizures in saudi children

    International Nuclear Information System (INIS)

    Objective: To identify the risk factors of recurrent febrile seizures (FS) in Saudi children in a Northern Province of Hail in Saudi Arabia. Study Design: Descriptive prospective study. Place and Duration of Study: Pediatric department, King Khalid Hospital Hail, Kingdom of Saudi Arabia from 01 October 2010 to 30 September 2011. Patients and Methods: A total of 132 children (age ranges from 03 months to 60 months) were included in the study, while they were admitted with the diagnosis of FS during the study period, in the Pediatric department of the King Khalid University Hospital, Hail. A predesigned study proforma was utilized for data collection. All the children included in the study were followed for a period of 01 year after discharge from the pediatric ward for any recurrence of FS. Results: During the study period 132 children were admitted for FS, the mean age of children in our sample was 16 months. There was a preponderance of male children. Among the causes of fever, mostly 63(47.73%) had symptoms of viral prodrome. Recurrent febrile seizure was found in 46 (34.85%) children. There was a statistically significant association between low temperature at onset of seizure and recurrent FS in 65.22% cases p-value= 0.001). Similarly, the association of duration of fever (= 6 hour) prior to onset of FS and recurrence was found to be significant in 56.52% (p-value= 0.001). Moreover it was found that lower age <12 months at onset of first FS and complex FS had a statistically significant association with its recurrence in 65.22% and 69.57% cases respectively p-value= 0.01 and 0.001). Non significant factors were sex and family history. Conclusion: FS is a common paediatric problem predominantly seen in males. Almost one third of these children are at risk for recurrence in later dates. The risk factors for these recurrences are modest rise in body temperature at the onset of seizure, younger age at presentation, onset of seizure within 6 hours of fever and

    Purpose: To evaluate the pattern and risks for intrahepatic recurrence after percutaneous radiofrequency (RF) ablation for hepatocellular carcinoma (HCC). Materials and methods: We studied 62 patients with 72 HCCs ({<=}4 cm) who were treated with percutaneous RF ablation. The mean follow-up period was 19.1 months (6.0-49.1). We assessed the incidence and cumulative disease-free survival of local tumor progression (LTP) and intrahepatic distant recurrence (IDR). To analyze the risk factors, we examined the following, for the LTP: (1) tumor diameter, (2) contact with vessels, (3) degree of approximation to hepatic hilum, (4) contact with hepatic capsule, (5) presence of ablative safety margin, (6) degree of benign periablational enhancement and (7) serum alpha-fetoprotein; for the IDR: (1) severity of hepatic disease, (2) presence of HBsAg, (3) serum alpha-fetoprotein, (4) whether RF ablation was the initial treatment and (5) multiplicity of tumor for IDR. Results: The incidence of overall recurrence, LTP and IDR was 62.9%, 26.4% and 53.2%, respectively. The cumulative disease-free survival rates were 52%, 82% and 56% at 1 year, 26%, 63% and 30% at 2 years, respectively. Univariate analysis showed that the significant risk factors for LTP were: a tumor with a diameter >3 cm, contact of HCC with a vessel and an insufficient safety margin (p < 0.05). A multivariate stepwise Cox hazard model showed that the measurement of a tumor diameter >3 cm and insufficient safety margin were independent factors. Only the increased serum alpha-fetoprotein was a significant risk factor for IDR (p < 0.05). Conclusion: Intrahepatic recurrence after percutaneous RF ablation is common. Large HCC (>3 cm) with high serum alpha-fetoprotein should be treated more aggressively because of higher risk for recurrence.

  4. Computed tomography-guided permanent brachytherapy for locoregional recurrent gastric cancer

    International Nuclear Information System (INIS)

    Locoregional recurrence is the typical pattern of recurrence in gastric cancer, and cannot be removed by surgery in most of the patients. We aimed to evaluate the feasibility and efficacy of computed tomography (CT)-guided brachytherapy for patients with locoregional recurrent gastric cancer. We reviewed the case histories of 28 patients with locoregional recurrent gastric cancer that were selected for CT- guided brachytherapy by a multidisciplinary team. The clinical data of the patients including patient characteristics, treatment parameters, short-term effects, and survival data were collected and analyzed. 15-75 125I seeds were implanted into each patient to produce a minimal peripheral dose (MPD) 100-160 Gy. Median day 0 dosimetry was significant for the following: V100 (the volume treated with the prescription dose) 95.8% (90.2-120.5%) and D90 (prescription dose received by at least 90% of the volume) 105.2% (98.0-124.6%) of prescription dose. No serious complications occurred during the study. Two months after brachytherapy, complete response, partial response and progressive disease were observed in 50.0%, 28.6% and 21.4% of patients, respectively. The median survival time was 22.0 ± 5.2 months, and the 1, 2,and 3-year survival rate was 89 ± 6%, 52 ± 10% and 11 ± 7%, respectively. A univariate analysis showed that the tumor size was a significant predictor of overall survival (P = 0.034). Patients with tumors <3 cm had relatively higher complete response rate (66.7%), compared to those with tumors >3 cm (30.8%). The PTV (planning target volume) smaller than 45 cm3 was significantly correlated with achieving complete tumor eradication in the treated region (P = 0.020). For selected patients with limited locoregional recurrent gastric cancer, CT-guided brachytherapy using 125I seeds implantation can provide a high local control rate, with minimal trauma

  5. Dual-energy perfusion-CT in recurrent pancreatic cancer. Preliminary results

    International Nuclear Information System (INIS)

    To evaluate the diagnostic performance of dual energy (DE) perfusion-CT for the differentiation between postoperative soft-tissue formation and tumor recurrence in patients after potentially curative pancreatic cancer resection. 24 patients with postoperative soft-tissue formation in the conventional regular follow-up CT acquisition after pancreatic cancer resection with curative intent were included prospectively. They were examined with a 64-row dual-source CT using a dynamic sequence of 34 DE acquisitions every 1.5 s (80 ml of iodinated contrast material, 370 mg/ml, flow rate 5 ml/s). Weighted average (linearly blended M0.5) 120 kVp-equivalent dual-energy perfusion image data sets were evaluated with a body-perfusion CT tool for estimating blood flow, permeability, and blood volume. Diagnosis was confirmed by histological study (n=4) and by regular follow-up. Final diagnosis was local recurrence of pancreatic cancer in 15 patients and unspecific postoperative tissue formation in 9 patients. The blood-flow values for recurrence tissue trended to be lower compared to postoperative tissue formation with 16.6 ml/100 ml/min and 24.7 ml/100 ml/min, respectively for weighted average 120 kVp-equivalent image data, which was not significant (n.s.) (p=0.06, significance level 0.05). Permeability- and blood-volume values were only slightly lower in recurrence tissue (n.s.). DE perfusion-CT is feasible in patients after pancreatic cancer resection and a promising functional imaging technique. As only a trend for lower perfusion values in local recurrence compared to unspecific postoperative alterations was found, the perfusion differences are not yet sufficient to differentiate between malignancy and unspecific postoperative alterations for this new technique. Further studies and technical improvements are needed to generate reliable data for this clinically highly relevant differentiation.

    Purpose: To report mature results of a large cohort of patients diagnosed with squamous cell carcinoma of the oropharynx who were treated with intensity modulated radiation therapy (IMRT). Methods and Materials: The database of patients irradiated at The University of Texas, M.D. Anderson Cancer Center was searched for patients diagnosed with oropharyngeal cancer and treated with IMRT between 2000 and 2007. A retrospective review of outcome data was performed. Results: The cohort consisted of 776 patients. One hundred fifty-nine patients (21%) were current smokers, 279 (36%) former smokers, and 337 (43%) never smokers. T and N categories and American Joint Committee on Cancer group stages were distributed as follows: T1/x, 288 (37%); T2, 288 (37%); T3, 113 (15%); T4, 87 (11%); N0, 88(12%); N1/x, 140 (18%); N2a, 101 (13%); N2b, 269 (35%); N2c, 122 (16%); and N3, 56 (7%); stage I, 18(2%); stage II, 40(5%); stage III, 150(19%); and stage IV, 568(74%). Seventy-one patients (10%) presented with nodes in level IV. Median follow-up was 54 months. The 5-year overall survival, locoregional control, and overall recurrence-free survival rates were 84%, 90%, and 82%, respectively. Primary site recurrence developed in 7% of patients, and neck recurrence with primary site control in 3%. We could only identify 12 patients (2%) who had locoregional recurrence outside the high-dose target volumes. Poorer survival rates were observed in current smokers, patients with larger primary (T) tumors and lower neck disease. Conclusions: Patients with oropharyngeal cancer treated with IMRT have excellent disease control. Locoregional recurrence was uncommon, and most often occurred in the high dose volumes. Parotid sparing was accomplished in nearly all patients without compromising tumor coverage.

Methods and Materials: The database of patients irradiated at The University of Texas, M.D. Anderson Cancer Center was searched for patients diagnosed with oropharyngeal cancer and treated with IMRT between 2000 and 2007. A retrospective review of outcome data was performed. Results: The cohort consisted of 776 patients. One hundred fifty-nine patients (21%) were current smokers, 279 (36%) former smokers, and 337 (43%) never smokers. T and N categories and American Joint Committee on Cancer group stages were distributed as follows: T1/x, 288 (37%); T2, 288 (37%); T3, 113 (15%); T4, 87 (11%); N0, 88(12%); N1/x, 140 (18%); N2a, 101 (13%); N2b, 269 (35%); N2c, 122 (16%); and N3, 56 (7%); stage I, 18(2%); stage II, 40(5%); stage III, 150(19%); and stage IV, 568(74%). Seventy-one patients (10%) presented with nodes in level IV. Median follow-up was 54 months. The 5-year overall survival, locoregional control, and overall recurrence-free survival rates were 84%, 90%, and 82%, respectively. Primary site recurrence developed in 7% of patients, and neck recurrence with primary site control in 3%. We could only identify 12 patients (2%) who had locoregional recurrence outside the high-dose target volumes. Poorer survival rates were observed in current smokers, patients with larger primary (T) tumors and lower neck disease. Conclusions: Patients with oropharyngeal cancer treated with IMRT have excellent disease control. Locoregional recurrence was uncommon, and most often occurred in the high dose volumes. Parotid sparing was accomplished in nearly all patients without compromising tumor coverage

    To evaluate the diagnostic performance of dual energy (DE) perfusion-CT for the differentiation between postoperative soft-tissue formation and tumor recurrence in patients after potentially curative pancreatic cancer resection. 24 patients with postoperative soft-tissue formation in the conventional regular follow-up CT acquisition after pancreatic cancer resection with curative intent were included prospectively. They were examined with a 64-row dual-source CT using a dynamic sequence of 34 DE acquisitions every 1.5 s (80 ml of iodinated contrast material, 370 mg/ml, flow rate 5 ml/s). Weighted average (linearly blended M0.5) 120 kVp-equivalent dual-energy perfusion image data sets were evaluated with a body-perfusion CT tool for estimating blood flow, permeability, and blood volume. Diagnosis was confirmed by histological study (n=4) and by regular follow-up. Final diagnosis was local recurrence of pancreatic cancer in 15 patients and unspecific postoperative tissue formation in 9 patients. The blood-flow values for recurrence tissue trended to be lower compared to postoperative tissue formation with 16.6 ml/100 ml/min and 24.7 ml/100 ml/min, respectively for weighted average 120 kVp-equivalent image data, which was not significant (n.s.) (p=0.06, significance level 0.05). Permeability- and blood-volume values were only slightly lower in recurrence tissue (n.s.). DE perfusion-CT is feasible in patients after pancreatic cancer resection and a promising functional imaging technique. As only a trend for lower perfusion values in local recurrence compared to unspecific postoperative alterations was found, the perfusion differences are not yet sufficient to differentiate between malignancy and unspecific postoperative alterations for this new technique. Further studies and technical improvements are needed to generate reliable data for this clinically highly relevant differentiation.

    Full Text Available BACKGROUND: Many men develop a rising PSA after initial therapy for prostate cancer. While some of these men will develop a local or metastatic recurrence that warrants further therapy, others will have no evidence of disease progression. We hypothesized that an expression biomarker panel can predict which men with a rising PSA would benefit from further therapy. METHODOLOGY/PRINCIPAL FINDINGS: A case-control design was used to test the association of gene expression with outcome. Systemic (SYS progression cases were men post-prostatectomy who developed systemic progression within 5 years after PSA recurrence. PSA progression controls were matched men post-prostatectomy with PSA recurrence but no evidence of clinical progression within 5 years. Using expression arrays optimized for paraffin-embedded tissue RNA, 1021 cancer-related genes were evaluated-including 570 genes implicated in prostate cancer progression. Genes from 8 previously reported marker panels were included. A systemic progression model containing 17 genes was developed. This model generated an AUC of 0.88 (95% CI: 0.84-0.92. Similar AUCs were generated using 3 previously reported panels. In secondary analyses, the model predicted the endpoints of prostate cancer death (in SYS cases and systemic progression beyond 5 years (in PSA controls with hazard ratios 2.5 and 4.7, respectively (log-rank p-values of 0.0007 and 0.0005. Genes mapped to 8q24 were significantly enriched in the model. CONCLUSIONS/SIGNIFICANCE: Specific gene expression patterns are significantly associated with systemic progression after PSA recurrence. The measurement of gene expression pattern may be useful for determining which men may benefit from additional therapy after PSA recurrence.

    Purpose: Current National Comprehensive Cancer Network guidelines recommend postoperative radiation therapy (PORT) for patients with resected non-small cell lung cancer (NSCLC) with N2 involvement. We investigated the relationship between nodal stage and local-regional recurrence (LR), distant recurrence (DR) and overall survival (OS) for patients having an R0 resection. Methods and Materials: A multi-institutional database of consecutive patients undergoing R0 resection for stage I-IIIA NSCLC from 1995 to 2008 was used. Patients receiving any radiation therapy before relapse were excluded. A total of 1241, 202, and 125 patients were identified with N0, N1, and N2 involvement, respectively; 161 patients received chemotherapy. Cumulative incidence rates were calculated for LR and DR as first sites of failure, and Kaplan-Meier estimates were made for OS. Competing risk analysis and proportional hazards models were used to examine LR, DR, and OS. Independent variables included age, sex, surgical procedure, extent of lymph node sampling, histology, lymphatic or vascular invasion, tumor size, tumor grade, chemotherapy, nodal stage, and visceral pleural invasion. Results: The median follow-up time was 28.7 months. Patients with N1 or N2 nodal stage had rates of LR similar to those of patients with N0 disease, but were at significantly increased risk for both DR (N1, hazard ratio [HR] = 1.84, 95% confidence interval [CI]: 1.30-2.59; P=.001; N2, HR = 2.32, 95% CI: 1.55-3.48; P<.001) and death (N1, HR = 1.46, 95% CI: 1.18-1.81; P<.001; N2, HR = 2.33, 95% CI: 1.78-3.04; P<.001). LR was associated with squamous histology, visceral pleural involvement, tumor size, age, wedge resection, and segmentectomy. The most frequent site of LR was the mediastinum. Conclusions: Our investigation demonstrated that nodal stage is directly associated with DR and OS but not with LR. Thus, even some patients with, N0-N1 disease are at relatively high risk of local recurrence. Prospective

  13. Long-Term Outcomes in Patients With Isolated Supraclavicular Nodal Recurrence After Mastectomy and Doxorubicin-Based Chemotherapy for Breast Cancer

    International Nuclear Information System (INIS)

    Purpose: To examine the outcome of patients who developed an isolated locoregional recurrence (LRR) involving the supraclavicular fossa (SCV) after initial treatment with modified radical mastectomy and chemotherapy. Methods and Materials: Records from 140 breast cancer patients treated on five prospective trials with mastectomy and doxorubicin-based chemotherapy, with or without radiation, who developed a LRR were reviewed. Kaplan-Meier survival times were calculated using date of LRR as time zero. Results: The median follow-up after LRR was 2.9 years (N = 140; interquartile range, 1.3-6.6 years). In all, 47 of 140 patients (34%) had an SCV component to their LRR. These patients had lower 3-y distant metastasis-free survival (40% vs. 54%, p = 0.003) and overall survival (49% vs. 69%, p = 0.04) than patients without an SCV component. Multivariate analysis revealed that LRR involving an SCV component (hazard ratio, 1.96, p = 0.004) and patients with lymphovascular space invasion in their primary tumors (hazard ratio, 1.65, p = 0.029) were independently associated with a poor distant metastasis-free survival. However, among 23 patients with isolated SCV recurrence, Overall survival was not statistically significantly different between isolated chest wall recurrence and isolated SCV recurrence. Patients with isolated SCV recurrence displayed a median follow-up of 3.3 years (IR, 1.2-5.2). Only 6 LRR of 23 patients were treated with aggressive local therapy, including surgery, chemotherapy, and radiation (alone or in combination). Conclusions: Although breast cancer recurrence with SCV involvement carries a high risk of distant metastasis and death, among women with recurrence limited to the SCV alone, overall survival after isolated SCV recurrence can be long (25% >5 years).

    Sally Stabler

    Full Text Available BACKGROUND: Clinical decision for primary treatment for prostate cancer is dictated by variables with insufficient specificity. Early detection of prostate cancer likely to develop rapid recurrence could support neo-adjuvant therapeutics and adjuvant options prior to frank biochemical recurrence. This study compared markers in serum and urine of patients with rapidly recurrent prostate cancer to recurrence-free patients after radical prostatectomy. Based on previous identification of urinary sarcosine as a metastatic marker, we tested whether methionine metabolites in urine and serum could serve as pre-surgical markers for aggressive disease. METHODOLOGY/PRINCIPAL FINDINGS: Urine and serum samples (n = 54 and 58, respectively, collected at the time of prostatectomy were divided into subjects who developed biochemical recurrence within 2 years and those who remained recurrence-free after 5 years. Multiple methionine metabolites were measured in urine and serum by GC-MS. The role of serum metabolites and clinical variables (biopsy Gleason grade, clinical stage, serum prostate specific antigen [PSA] on biochemical recurrence prediction were evaluated. Urinary sarcosine and cysteine levels were significantly higher (p = 0.03 and p = 0.007 respectively in the recurrent group. However, in serum, concentrations of homocysteine (p = 0.003, cystathionine (p = 0.007 and cysteine (p<0.001 were more abundant in the recurrent population. The inclusion of serum cysteine to a model with PSA and biopsy Gleason grade improved prediction over the clinical variables alone (p<0.001. CONCLUSIONS: Higher serum homocysteine, cystathionine, and cysteine concentrations independently predicted risk of early biochemical recurrence and aggressiveness of disease in a nested case control study. The methionine metabolites further supplemented known clinical variables to provide superior sensitivity and specificity in multivariable prediction models for

    Objective:To study and investigate the relationship between the serum vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP), midkine (MK) and recurrence and metastasis after gastric cancer surgery.Methods:A total of 78 patients with recurrence and metastasis after gastric cancer surgery in our hospital from January 212 to June 2015 were selected as Group A, 78 patients without recurrence and metastasis at the same time were selected as Group B and 78 healthy persons were selected as Group C. Then the serum VEGF, MMP and MK levels of the 3 groups were compared. The detection levels of local recurrence, regional lymphatic metastasis and distant metastasis in Group A were also compared, and the relationship between the serum VEGF, MMP, MK and recurrence and metastasis after gastric cancer surgery was analyzed by the Logistic analysis.Results:The serum VEGF, MMP and MK indexes of Group A were all higher than those of Group B and Group C. The levels of Group B and Group C had no significant differences. Meanwhile, in Group A, the detection levels of regional lymphatic metastasis and distant metastasis were all higher than those of patients with local recurrence. According to the Logistic analysis, the above indexes all had close relationship with the recurrence and metastasis after gastric cancer surgery.Conclusions:The serum VEGF, MMP and MK of patients with recurrence and metastasis after gastric cancer surgery show higher expression state, and those indexes all have close relationship with the disease.

    2015-01-01

    BACKGROUND: Limited data suggest that statin use reduces the risk for ovarian cancer. METHODS: Using Danish nationwide registries, we identified 4103 cases of epithelial ovarian cancer during 2000-2011 and age-matched them to 58,706 risk-set sampled controls. Conditional logistic regression was...... used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for epithelial ovarian cancer overall, and for histological types, associated with statin use. RESULTS: We observed a neutral association between ever use of statins and epithelial ovarian cancer risk (OR=0.98, 95% CI=0.......87-1.10), and no apparent risk variation according to duration, intensity or type of statin use. Decreased ORs associated with statin use were seen for mucinous ovarian cancer (ever statin use: OR=0.63, 95% CI=0.39-1.00). CONCLUSIONS: Statin use was not associated with overall risk for epithelial ovarian cancer...

    Concerns remain over the risk of cancer following differentiated thyroid carcinoma and its causes. Iodine-131 ({sup 131}I) and external irradiation are known to have potential carcinogenic effects. Thyroid carcinoma is a polygenic disease which may be associated with other malignancies. We investigated the incidence of second cancer and its aetiology in a cohort of 875 patients (146 men, 729 women) with differentiated thyroid carcinoma originating from Basse-Normandie, France. Cancer incidence was compared with that of the general population of the Departement du Calvados matched for age, gender and period. The cumulative proportion of second cancer was estimated using the life-table method. Factors that correlated with the risk of second cancer were studied using the Cox model. After a median follow-up of 8 years, 58 second cancers had been observed. Compared with general population incidence rates, there was an overall increased risk of second cancer in women [standardised incidence ratio (SIR)=1.52; P<0.01], but not in men (SIR=1.27; P>0.20). Increased risk related to cancers of the genitourinary tract (SIR=3.31; P<0.001), and particularly to cancer of the kidney (SIR=7.02; P<0.01). Multivariate analysis showed that age above 40 years (P<0.01) and a history of previous primary cancer (P<0.001) correlated with risk. In contrast, neither cervical irradiation nor cumulative activity of {sup 131}I was related to the risk. These data confirm that women with differentiated thyroid carcinoma are at risk of developing a second cancer of the genitourinary tract and kidney. Only age and medical history of primary cancer before thyroid carcinoma are risk factors for second cancer. Common environmental or genetic factors as well as long-term carcinogenic effects of primary cancer therapy should be considered. (orig.)

    Full Text Available Breast cancer is strongly influenced by hereditary risk factors, a majority of which still remain unknown. Here, we performed a targeted next-generation sequencing of 796 genes implicated in DNA repair in 189 Finnish breast cancer cases with indication of hereditary disease susceptibility and focused the analysis on protein truncating mutations. A recurrent heterozygous mutation (c.904_916del, p.Arg304ValfsTer3 was identified in early DNA damage response gene, MCPH1, significantly associating with breast cancer susceptibility both in familial (5/145, 3.4%, P = 0.003, OR 8.3 and unselected cases (16/1150, 1.4%, P = 0.016, OR 3.3. A total of 21 mutation positive families were identified, of which one-third exhibited also brain tumors and/or sarcomas (P = 0.0007. Mutation carriers exhibited significant increase in genomic instability assessed by cytogenetic analysis for spontaneous chromosomal rearrangements in peripheral blood lymphocytes (P = 0.0007, suggesting an effect for MCPH1 haploinsufficiency on cancer susceptibility. Furthermore, 40% of the mutation carrier tumors exhibited loss of the wild-type allele. These findings collectively provide strong evidence for MCHP1 being a novel breast cancer susceptibility gene, which warrants further investigations in other populations.

    The debate about the impact of local control on survival in early breast cancer patients is still going on, in spite of the continuously growing evidence that avoidance of locoregional disease reduces the risk of tumor-specific death. Recently, B. Fisher, one of the pioneers of breast conserving therapy claimed that during the last two decades, as a result of the use of systemic therapy in conjunction with breast conserving surgery and radiation, the incidence of locoregional recurrence has been reduced to a level where further reduction is likely to have little impact on survival. The penultimate meta-analysis of the Early Breast Cancer Trialists' Collaborative Group (EBCTCG) reported the effect of radiotherapy in early breast cancer on recurrence and survival in 2005 and provided the essential message that four prevented local recurrences at 5 years would avoid one breast cancer death in 15 years. The scientific community has eagerly awaited the quinquennial update of the EBCTCG which has now been published. A total of 17 randomized studies comparing postoperative radiotherapy vs. none were analyzed and comprised 7 new studies in addition to follow-up data of from 9 previously reported trials. A total of 10,801 patients with pT1-2 tumors were included, the majority of whom (n=7,287) were node negative, while 1,050 were node positive (2,464 unknown). In contrast to the previous meta-analysis, all patients received breast conserving surgery, consisting of lumpectomy (n=8,422) or more extensive techniques like quadrantectomy or sectoral resection (n= 2,399). The effect of radiotherapy on 10-year recurrences of any type and their relation to the 15-year breast cancer death rate were studied in correlation to various prognostic parameters and treatment characteristics (e.g., surgery, tamoxifen use). Moreover, a subgroup analysis was performed according to low, intermediate, and high initial risk of recurrence, from which the expected absolute benefit was derived

    Stereotactic ablative radiotherapy (SABR) has recently become a standard treatment option for patients with early-stage lung cancer, which achieves local control rates similar to surgery. Local recurrence following SABR typically presents after one year post-treatment. However, benign radiological changes mimicking local recurrence can appear on CT imaging following SABR, complicating the assessment of response. We hypothesize that subtle changes on early post- SABR CT images are important in predicting the eventual incidence of local recurrence and would be extremely valuable to support timely salvage interventions. The objective of this study was to extract radiomic image features on post-SABR follow-up images for 45 patients (15 with local recurrence and 30 without) to aid in the early prediction of local recurrence. Three blinded thoracic radiation oncologists were also asked to score follow-up images as benign injury or local recurrence. A radiomic signature consisting of five image features demonstrated a classification error of 24%, false positive rate (FPR) of 24%, false negative rate (FNR) of 23%, and area under the receiver operating characteristic curve (AUC) of 0.85 at 2-5 months post-SABR. At the same time point, three physicians assessed the majority of images as benign injury for overall errors of 34-37%, FPRs of 0-4%, and FNRs of 100%. These results suggest that radiomics can detect early changes associated with local recurrence which are not typically considered by physicians. We aim to develop a decision support system which could potentially allow for early salvage therapy of patients with local recurrence following SABR.

  5. [18F]fluoroethylcholine-PET/CT imaging for radiation treatment planning of recurrent and primary prostate cancer with dose escalation to PET/CT-positive lymph nodes

    International Nuclear Information System (INIS)

    At present there is no consensus on irradiation treatment volumes for intermediate to high-risk primary cancers or recurrent disease. Conventional imaging modalities, such as CT, MRI and transrectal ultrasound, are considered suboptimal for treatment decisions. Choline-PET/CT might be considered as the imaging modality in radiooncology to select and delineate clinical target volumes extending the prostate gland or prostate fossa. In conjunction with intensity modulated radiotherapy (IMRT) and imaged guided radiotherapy (IGRT), it might offer the opportunity of dose escalation to selected sites while avoiding unnecessary irradiation of healthy tissues. Twenty-six patients with primary (n = 7) or recurrent (n = 19) prostate cancer received Choline-PET/CT planned 3D conformal or intensity modulated radiotherapy. The median age of the patients was 65 yrs (range 45 to 78 yrs). PET/CT-scans with F18-fluoroethylcholine (FEC) were performed on a combined PET/CT-scanner equipped for radiation therapy planning. The majority of patients had intermediate to high risk prostate cancer. All patients received 3D conformal or intensity modulated and imaged guided radiotherapy with megavoltage cone beam CT. The median dose to primary tumours was 75.6 Gy and to FEC-positive recurrent lymph nodal sites 66,6 Gy. The median follow-up time was 28.8 months. The mean SUVmax in primary cancer was 5,97 in the prostate gland and 3,2 in pelvic lymph nodes. Patients with recurrent cancer had a mean SUVmax of 4,38. Two patients had negative PET/CT scans. At 28 months the overall survival rate is 94%. Biochemical relapse free survival is 83% for primary cancer and 49% for recurrent tumours. Distant disease free survival is 100% and 75% for primary and recurrent cancer, respectively. Acute normal tissue toxicity was mild in 85% and moderate (grade 2) in 15%. No or mild late side effects were observed in the majority of patients (84%). One patient had a severe bladder shrinkage (grade 4) after a

    Full Text Available The incidence of thyroid cancer is rising in the United States with papillary thyroid cancer (PTC being the most common type. We performed a retrospective study of 49 patients with PTC who underwent 57 lateral neck dissections (NDs. The extent of NDs varied, but 29 of 57 (51% consisted of levels II–V. Twelve of 57 (21% NDs consisted of levels I–V. Twelve of 57 (21% NDs consisted of levels II–IV. One of 57 (1.8% necks involved only levels I–IV. One of 57(1.8% necks involved only levels I–V. One of 57(1.8% necks involved only levels III–V. Two (3.5% double-level (III–IV neck surgeries were also performed. Metastatic PTC adenopathy was confirmed pathologically in 2%-level-I, 45%-level-II, 57%-level-III, 60%-level-IV, and 22%-level-V necks. Level-V was positive in 21% of primary and 24% of recurrent groups (=0.76. Comparing primary and recurrent disease, there was no difference in nodal distribution or frequency for levels I, II, III, and V. Level-IV was more common in the recurrent cases (=0.05. Based on the pathologic distribution of nodes, dissection should routinely include levels II–IV and extend to level-V in primary and recurrent cases. Our data does not suggest routine dissection of level-I.

    Segmental ureterectomy is less invasive than radical nephroureterectomy and results in nephron preservation and satisfactory tumor control. This study was to determine the feasibility of segmental ureteroileal conduit resection (SUICR) for patients with distal upper urinary tract recurrence of bladder cancer following radical cystectomy. Four patients with high‑grade distal upper urinary tract recurrence underwent SUICR 15–108months after radical cystec‑tomy. The surgical technique details of SUICR, operative results, and follow‑up outcomes are reported. The median operation time was 280min, and estimated blood loss was less than 100mL. One patient suffered from ileus 5days after surgery and was managed conservatively. Histopathologic evaluation showed high‑grade stages pTa‑pT1 diseases for these patients, and ureteral margins were all negative. No patient suffered from tumor recurrence, with a median follow‑up of 39months. SUICR preserved the ipsilateral renal unit and conformed to oncological principles during surgery. The oncological outcome was satisfactory for these properly selected patients. This technique pro‑vides a valid alternative to nephroureterectomy for patients with imperative indications and high‑grade upper urinary tract recurrence of bladder cancer following radical cystectomy.

    Full Text Available Introduction and objective: Overexpression of MMPs has been related to biochemical recurrence after radical prostatectomy. TIMP1 and TIMP2 are controllers of MMPs and the aim of this study is to evaluate the expression levels of MMPs and their regulators using immunohistochemistry in tissue microarray of localized prostate cancer (PC. Materials and Methods: Immune-expression of MMP-9, MMP-2, TIMP1, TIMP-2, MMP-14 and IL8, were analyzed by immunohistochemistry in radical prostatectomy specimens of 40 patients with localized PC who underwent surgery between September 1997 and February 2000. Protein expression was considered as categorical variables, negative or positive. The results of the immune-expression were correlated to Gleason score (GS, pathological stage (TNM, pre-operatory PSA serum levels and biochemical recurrence in a mean follow up period of 92.5 months. Results: The loss of TIMP1 immune-expression was related to biochemical recurrence. When TIMP1 was negative, 56.3% patients recurred versus 22.2% of those whose TIMP1 was positive (p=0.042. MMP-9, MMP-2, IL8 and MMP-14 were positive in the majority of PC. TIMP-2 was negative in all cases. Conclusion: Negative immune-expression of TIMP1 is correlated with biochemical recurrence in patients with PC possibly by failing to control MMP-9, an important MMP related to cancer progression.

    Full Text Available Abstract Background Breast cancer is one of the major public health problems among women worldwide. A number of epidemiological studies have been carried out to find the role of dietary fat and the risk of breast cancer. The main objective of the present communication is to summarize the evidence from various case-control and cohort studies on the consumption of fat and its subtypes and their effect on the development of breast cancer. Methods A Pubmed search for literature on the consumption of dietary fat and risk of breast cancer published from January 1990 through December 2003 was carried out. Results Increased consumption of total fat and saturated fat were found to be positively associated with the development of breast cancer. Even though an equivocal association was observed for the consumption of total monounsaturated fatty acids (MUFA and the risk of breast cancer, there exists an inverse association in the case of oleic acid, the most abundant MUFA. A moderate inverse association between consumption of n-3 fatty acids and breast cancer risk and a moderate positive association between n-6 fatty acids and breast cancer risk were observed. Conclusion Even though all epidemiological studies do not provide a strong positive association between the consumption of certain types of dietary fat and breast cancer risk, at least a moderate association does seem to exist and this has a number of implications in view of the fact that breast cancer is an increasing public health concern.

    To evaluate the potential of thioredoxin (TXN)and thioredoxin-interacting protein (TXNIP) expression as biomarkers for predicting gastric cancer recurrence.METHODS:TXN and TXNIP expression levels were acquired from gene expression microarray data for 65human gastric cancer tissues.We determined whether each gene expression level was associated with cancer recurrence and investigated the relationship between the two genes.For validation,the expression levels of TXN and TXNIP were measured by quantitative realtime reverse transcription polymerase chain reaction in 68 independent stage Ⅲ gastric cancer patients.The correlation between gene expression and cancer prognosis was evaluated.Immunohistochemical staining was performed to investigate the protein expression levels of TXN and TXNIP and to characterize the expression patterns of each protein.RESULTS:TXN was a prognosis-related gene (P =0.009),whereas TXNIP,a TXN inhibitor,demonstrated a negative correlation with TXN in the gene expression microarray data.In the 68 stage Ⅲ patients,the expression levels of both TXN and TXNIP had a statistically significant effect on recurrence-free survival (RFS,P =0.008 and P =0.036,respectively).The low TXN and high TXNIP expression group exhibited a better prognosis than the other groups,and the high TXN and low TXNIP expression group exhibited a poorer prognosis (P < 0.001 for RFS and P =0.001 for overall survival).More than half of the patients in the simultaneously high TXN and low TXNIP expression group experienced a recurrence within 1 year after curative surgery,and the 5-year survival rate of the patients in this group was 29%,compared with 89% in the low TXN and high TXNIP expression group.The TXN protein was overexpressed in 65% of the gastric cancer tissues,whereas the TXNIP protein was underexpressed in 85% of the cancer cells.In a correlation analysis,TXN and TXNIP were highly correlated with many oncogenes and tumor suppressors as well as with genes

    AIM: To develop and validate a risk score for advanced colorectal adenoma (ACA) recurrence after endoscopic polypectomy. METHODS: Out of 3360 patients who underwent colon polypectomy at University of Foggia between 2004 and 2008, data of 843 patients with 1155 ACAs was retrospectively reviewed. Surveillance intervals were scheduled by guidelines at 3 years and primary endpoint was considered 3-year ACA recurrence. Baseline clinical parameters and the main features of ACAs were entered into a Cox regression analysis and variables with P < 0.05 in the univariate analysis were then tested as candidate variables into a stepwise Cox regression model (conditional backward selection). The regression coefficients of the Cox regression model were multiplied by 2 and rounded in order to obtain easy to use point numbers facilitating the calculation of the score. To avoid overoptimistic results due to model fitting and evaluation in the same dataset, we performed an internal 10-fold cross-validation by means of bootstrap sampling. RESULTS: Median lesion size was 16 mm (12-23) while median number of adenomas was 2.5 (1-3), whereof the number of ACAs was 1.5 (1-2). At 3 years after polypectomy, recurrence was observed in 229 ACAs (19.8%), of which 157 (13.5%) were metachronous neoplasms and 72 (6.2%) local recurrences. Multivariate analysis, after exclusion of the variable “type of resection” due to its collinearity with other predictive factors, confirmed lesion size, number of ACAs and grade of dysplasia as significantly associated to the primary outcome. The score was then built by multiplying the regression coefficients times 2 and the cut-off point 5 was selected by means of a Receiver Operating Characteristic curve analysis. In particular, 248 patients with 365 ACAs fell in the higher-risk group (score ≥ 5) where 3-year recurrence was detected in 174 ACAs (47.6%) whereas the remaining 595 patients with 690 ACAs were included in the low-risk group (score < 5) where 3

    For tumors of the lower third of the rectum, the only safe surgical procedure is abdominal-perineal resection. High-dose-rate interstitial brachytherapy is a promising treatment for local recurrence of previously irradiated lower rectal cancer, due to the extremely high concentrated dose delivered to the tumor and the sparing of normal tissue, when compared with a course of external beam radiation therapy.

    Background Correct drug selection, the key to successful chemotherapy, is one of the most difficult clinical decisions for the treatment of platinum-resistant recurrent ovarian cancer worldwide. The exact procedures for choosing drugs are undefined, currently relying on clinical trials and personal experience, which often results in disappointing outcomes. Here, we propose a new drug selection method, the "predictive molecule targeted routine chemotherapy", to choose relatively sensitive routine drugs and avoid relatively resistant routine drugs based on the specific predictive molecule expression of the individual tumor tissue.Methods From January 2004 to June 2008,26 cases of platinum-resistant recurrent ovarian cancer were prospectively recruited. Their routine chemotherapy drug choice was based on the expression of 6 predictive molecules (including p53) as determined by immunohistochemistry (the predictive molecule targeted routine chemotherapy group). A further 18 cases of platinum-resistant recurrent ovarian cancer were treated by experience and formed the control group. The response rate and the overall survival were compared between the two groups.Results The response rate to second-line chemotherapy was 28% in the control group and 77% in the predictive molecule targeted routine chemotherapy group (P=0.002). The response rate to third-line chemotherapy was 14% in the control group and 33% in the predictive molecule targeted routine chemotherapy group (P=0.268). The median overall survival of the predictive molecule targeted routine chemotherapy group (88 weeks) was significantly longer than the median overall survival of the control group (56 weeks) (P=0.0315).Conclusion The predictive molecule targeted routine chemotherapy is a new effective protocol for choosing drugs when treating platinum-resistant recurrent ovarian cancer.

    Photodynamic therapy (PDT) of locally recurrent breast cancer has been limited to treatment of small lesions because of non- selective necrosis of adjacent normal tissues in the treatment field. Lutetium Texaphyrin (PCI-0123, Lu-Tex) is a photosensitizer with improved tumor localization that is activated by 732 nm light, which can penetrate through larger tumors. We have evaluated Lu-Tex in a Phase I trial and in an ongoing Phase II trial in women with locally recurrent breast cancer with large tumors who have failed radiation therapy. Patients received Lu-Tex intravenously by rapid infusion 3 hours before illumination of cutaneous or subcutaneous lesions. In Phase I, Lu-Tex doses were escalated from 0.6 to 7.2 mg/kg in 7 cohorts. Sixteen patients with locally recurrent breast cancer lesions were treated. Dose limiting toxicities above 5.5 mg/kg were pain in the treatment field during therapy, and dysesthesias in light exposed areas. No necrosis of normal tissues in the treated field was noticed. Responses were observed in 60% of evaluable patients [n equals 15, 27% complete remission (CR), 33% partial remission (PR)], with 63% of lesions responding (n equals 73: 45% CR, 18% PR). In Phase II, 25 patients have been studied to date, receiving two treatments ranging from 1.0 to 3.0 mg/kg at a 21 day interval. Treatment fields up to 480 cm2 in size were treated successfully and activity has been observed. Patients have experienced pain at the treatment site but no tissue necrosis. These studies demonstrate the feasibility of Lu-Tex PDT to large chest wall areas in women who have failed radiation therapy for the treatment of locally recurrent breast cancer. Treatment conditions are currently being optimized in the ongoing Phase II trials.

    Full Text Available Abstract Background Biomarkers that predict clinical response, tumor recurrence or patient survival are severely lacking for most cancers, particularly for oral and pharyngeal cancer. This study examines whether gene-promoter methylation of tumor DNA correlates with survival and recurrence rates in a population of patients with oral or pharyngeal cancer. Methods The promoter methylation status of the DNA repair gene MGMT and the tumor suppressor genes CDKN2A and RASSF1 were evaluated by methylation-specific PCR in 88 primary oral and pharyngeal tumors and correlated with survival and tumor recurrence. Quantitative MGMT methylation was also assessed. Results 29.6% of the tumors presented with MGMT methylation, 11.5% with CDKN2A methylation and 12.1% with RASSF1 methylation. MGMT promoter methylation was significantly associated with poorer overall and disease-free survival. No differences in methylation status of MGMT and RASSF1 with HPV infection, smoking or drinking habits were observed. A significant inverse trend with the amount of MGMT methylation and overall and disease-free survival was observed (ptrend = 0.002 and 0.001 respectively. Conclusion These results implicate MGMT promoter methylation as a possible biomarker for oral and pharyngeal cancer prognosis. The critical role of MGMT in DNA repair suggests that defective DNA repair may be correlative in the observed association between MGMT promoter methylation and tumor recurrence. Follow-up studies should include further quantitative MSP-PCR measurement, global methylation profiling and detailed analysis of downstream DNA repair genes regulated by promoter methylation.

We hypothesize that activation of the SHH pathway contributes to the recurrence of breast carcinoma.Methods: Fifty consecutive patients with invasive breast carcinoma following curative resection were enrolled in this prospective study. The ratios of messenger RNA (mRNA expression for Sonic Hedgehog (SHH, patched homolog-1 (PTCH-1, glioma-associated oncogene-1 (GLI-1, and smoothened (SMOH were measured between breast carcinoma tissue and paired noncancerous breast tissue. These ratios were compared with their clinicopathologic characteristics. These factors and the mRNA ratios were compared between patients with recurrence and those without recurrence.Results: The size of the invasive cancer correlated significantly with the ratio of SHH mRNA (P=0.001, that of PTCH-1 mRNA (P=0.005, and that of SMOH mRNA (P=0.021. Lymph node involvement correlated significantly with the ratio of SMOH mRNA (P=0.041. The correlation between Her-2 neu and the ratio of GLI-1 mRNA was statistically significant (P=0.012. Each ratio of mRNA of SHH, PTCH-1, GLI-1, and SMOH correlated significantly with cancer recurrence (P<0.001 for each.Conclusion: We suggest that high expression of SHH mRNA, PTCH-1 mRNA, GLI-1 mRNA, and SMOH mRNA in breast cancer tissue correlates with invasiveness and is a potential biomarker to predict postoperative recurrence.Keywords: SHH pathway, breast carcinoma, prediction,
