    Therapy-related myeloid neoplasms (t-MN) account for approximately 10% to 20% of all cases of AML (acute myeloid leukemia), MDS (myelodysplastic syndrome) and MDS/MPN (myelodysplastic syndrome/myeloproliferative neoplasms), MDS, and MDS/MPN. In our study, we evaluated peripheral blood smear samples and hemogram values in breast cancer patients who were receiving adjuvant anthracycline regimens and were in remission. A total of 78 patients receiving anthracycline-based adjuvant chemotherapy treatment from Kayseri Research and Training Hospital and Mersin State Hospital were enrolled in the study. Their adjuvant treatments had been completed at least 18 months prior to the study. Two patients complained of anemia (2.2%) (HbHowell-Jolly bodies (1%). Additionally, hypo-granulation (38%), Pelger-Huet abnormalities (26%), hypersegmentation (20%), immature granulocytes (8%), and blasts (6%) were observed. We also confirmed the presence of giant platelets (50%) and platelet hypogranulation (19%). According to the peripheral blood smear assessments in our study, we suggest that breast cancer patients should be evaluated for MDS in the early stages, starting from month 18, even if the automated blood counts are normal.

    Background: Adjuvant radiotherapy combined with 5-fluorouracil based chemotherapy has become the new standard after curative resection in high risk gastric cancer. Beside many complications due to surgery, the addition of chemotherapy and radiotherapy as adjuvant treatment may lead to both acute and late toxicities. Pancreatic tissue irradiation during this adjuvant treatment because of incidental and unavoidable inclusion of the organ within the radiation field may affect exocrine and endocrine functions of the organ. Materials and methods: Fifty-three patients with gastric adenocarcinoma were evaluated for adjuvant chemoradiotherapy after surgery. While 37 out of 53 patients were treated postoperatively due to either serosal or adjacent organ or lymph node involvement, 16 patients without these risk factors were followed up regularly without any additional treatment and they served as the control group. Fasting blood glucose (FBG), hemoglobin A1c (HBA1c), insulin and C-peptide levels were measured in the control and study groups after the surgery and 6 months and 1 year later. Results: At the baseline there was no difference in FBG, HbA1c, C-peptide and insulin levels between the control and the study groups. At the end of the study there was a statistically significant decline in insulin and C-peptide levels in the study group, (7.5 ± 6.0 vs 4.5 ± 4.4 IU/L, p: 0.002 and 2.3 ± 0.9 vs 1.56 ± 0.9 ng/ml, p: 0.001) respectively. Conclusions: Adjuvant radiotherapy in gastric cancer leads to a decrease in beta cell function and insulin secretion capacity of the pancreas with possible diabetes risk. Radiation-induced pancreatic injury and late effects of radiation on normal pancreatic tissue are unknown, but pancreas is more sensitive to radiation than known. This organ should be studied extensively in order to determine the tolerance doses and it should be contoured during abdominal radiotherapy planning as an organ at risk

    Full Text Available PURPOSE: The role of adjuvant chemotherapy in patients with locally advanced bladder cancer still remains to be defined. We hypothesized that assessing the gene expression of the chemotherapy response modifiers multidrug resistance gene 1 (MDR1 and excision repair crosscomplementing 1 (ERCC1 may help identify the group of patients benefiting from cisplatin-based adjuvant chemotherapy. EXPERIMENTAL DESIGN: Formalin-fixed paraffin-embedded tumor samples from 108 patients with locally advanced bladder cancer, who had been enrolled in AUO-AB05/95, a phase 3trial randomizing a maximum of three courses of adjuvant cisplatin and methotrexate (CM versus methotrexate, vinblastine, epirubicin, and cisplatin (M VEC, were included in the study. Tumor cells were retrieved by laser-captured microdissection and analyzed for MDR1 and ERCC1 expression using a quantitative real-time reverse transcription-polymerase chain reaction assay. Gene expression levels were correlated with clinical outcomes by multivariate Cox proportional hazards regression analysis. RESULTS: Expressions of MDR1 and ERCC1 were independently associated with overall progression-free survival (P = .001, relative risk = 2.9 and P = .01, relative risk = 2.24, respectively. The correlation of high MDR1 expression with inferior outcome was stronger in patients receiving M-VEC, whereas ERCC1 analysis performed equally in the CM and M-VEC groups. CONCLUSIONS: High MDR1 and ERCC1 gene expressions are associated with inferior outcome after cisplatin-based adjuvant chemotherapy for locally advanced bladder cancer. Prospective studies are warranted to define a role for MDR1 and ERCC1 analysis in individualizing multimodality treatment in locally advanced bladder cancer.

    Oral mucositis is a major cause of pain and delayed cancer treatment leading to poor survival in head and neck cancer patients receiving concurrent chemoradiation. The study evaluated the effect of adjuvant melatonin on minimizing oral mucositis complications to reduce these treatment delays and interruptions. A randomized, double-blind, double dummy, placebo-controlled clinical trial. Ubon Ratchathani Cancer Hospital, Thailand. Thirty-nine head and neck cancer patients receiving concurrent chemoradiation (5 days/week of radiation plus chemotherapy three or six cycles). Patients were randomized to receive 20 mg melatonin gargle (or matched placebo) before each irradiation, and 20 mg melatonin capsules (or matched placebo) taken nightly during 7 weeks of concurrent chemoradiation. Endpoints were oral mucositis events (incidence and time to grade 3 mucositis or grade 2 xerostomia), pain medication consumption and quality of life (QOL). Melatonin group reported lower incidence of grade 3 oral mucositis (42% vs. 55%) and grade 2 xerostomia (20% vs. 21%); no statistical significance was detected. Melatonin regimen delayed onset of grade 3 mucositis (median 34 days vs. 50 days; p = 0.0318), allowing median time of 16 more patient visits before its onset and fewer interrupted treatments due to oral mucositis were reported (n = 1 vs. n = 5). There was no difference of grade 2 xerostomia (median 32 days vs. 50 days; p = 0.624). Morphine consumption was also reduced (median 57 mg vs. 0 mg; p = 0.0342), while QOL was comparable during the study period. Adjuvant melatonin delayed the onset of oral mucositis, which enables uninterrupted cancer treatment and reduced the amount of morphine used for pain treatment.

    Breast cancer chemotherapy may cause unfavorable changes in physical functioning, body composition, psychosocial functioning, and quality of life (QOL). We evaluated the relative merits of aerobic and resistance exercise in blunting these effects. We conducted a multicenter randomized controlled trial in Canada between 2003 and 2005 that randomly assigned 242 breast cancer patients initiating adjuvant chemotherapy to usual care (n = 82), supervised resistance exercise (n = 82), or supervised aerobic exercise (n = 78) for the duration of their chemotherapy (median, 17 weeks; 95% CI, 9 to 24 weeks). Our primary end point was cancer-specific QOL assessed by the Functional Assessment of Cancer Therapy-Anemia scale. Secondary end points were fatigue, psychosocial functioning, physical fitness, body composition, chemotherapy completion rate, and lymphedema. The follow-up assessment rate for our primary end point was 92.1%, and adherence to the supervised exercise was 70.2%. Unadjusted and adjusted mixed-model analyses indicated that aerobic exercise was superior to usual care for improving self-esteem (P = .015), aerobic fitness (P = .006), and percent body fat (adjusted P = .076). Resistance exercise was superior to usual care for improving self-esteem (P = .018), muscular strength (P exercise groups but did not reach statistical significance. Exercise did not cause lymphedema or adverse events. Neither aerobic nor resistance exercise significantly improved cancer-specific QOL in breast cancer patients receiving chemotherapy, but they did improve self-esteem, physical fitness, body composition, and chemotherapy completion rate without causing lymphedema or significant adverse events.

    Chemotherapy-induced alopecia (CIA) is a distressing adverse effect of many chemotherapy agents. The TC (docetaxel [Taxotere] and cyclophosphamide) chemotherapy regimen is typically associated with complete alopecia. Scalp cooling with cold caps has been reported to minimize or prevent CIA. We conducted a prospective study to assess efficacy of scalp cooling in preventing CIA among women receiving adjuvant TC chemotherapy for breast cancer. Women at the Weill Cornell Breast Center who independently elected to use scalp cooling with cold caps during adjuvant TC chemotherapy were asked to participate. Degree of hair loss was assessed by a single practitioner using Dean's alopecia scale (grade 1/excellent [ 75% hair loss]), by digital photographs, and by patient self-report of hair thinning or the need to wear a wig/head covering, or both. Assessments were made before each chemotherapy treatment and at follow-up visits between 3 weeks and 3 months after completion of chemotherapy. Of 20 evaluable patients, 10% reported a need to wear a wig/head covering at the follow-up visit. Dean's alopecia score was excellent for 65% of patients, good for 25% of patients, and moderate or poor for 10% of patients. The majority of patients reported hair thinning after every chemotherapy cycle. No patient discontinued therapy because of an intolerance to cold caps. Scalp cooling with cold caps appears to be effective in preventing CIA among the majority of women undergoing treatment with TC chemotherapy. Copyright © 2015 Elsevier Inc. All rights reserved.

    To explore the efficacy of mindfulness-
based music therapy (MBMT) to improve attention and decrease mood distress experienced by women with breast cancer receiving adjuvant chemotherapy. Quantitative, descriptive, longitudinal approach. A comprehensive cancer hospital and a university in southern Florida. 15 women with a diagnosis of breast cancer, stages I-III, receiving adjuvant chemotherapy. Participants individually received MBMT for one hour per week for four weeks. The sessions consisted of varied music activities accompanied by mindfulness attitudes, or mental strategies that enhance moment-to-moment awareness, and weekly homework. Demographic information was collected at baseline. Attention was measured using Conners' Continuous Performance Test II. Mood was measured using the Profile of Mood States-Brief Form. Narrative comments collected from the homework assignments served to reinforce quantitative data. Repeated measures analysis of variance showed that attention improved significantly over time. Although all mood states significantly improved from the beginning to the end of each MBMT session, the mood state of fatigue decreased significantly more than the other mood states. MBMT enhances attention and mood, particularly the mood state of fatigue, in women with breast cancer receiving adjuvant chemotherapy. 
. A preferred music listening and mindfulness exercise may be offered to women with breast cancer who experience attention problems and mood distress.

    The purpose of this study is to assess temporal trends in the use of granulocyte colony-stimulating factor (G-CSF) prophylaxis and risk of febrile neutropenia (FN) among older women receiving adjuvant chemotherapy for early-stage breast cancer. Women aged ≥ 66 years with diagnosis of early-stage breast cancer who initiated selected adjuvant chemotherapy regimens were identified using the SEER-Medicare data from 2002 to 2012. Adjusted, calendar-year-specific proportions were estimated for use of G-CSF primary prophylaxis (PP) and secondary prophylaxis and FN risk in the first and the second/subsequent cycles during the first course of chemotherapy, using logistic regression models. calendar-year-specific mean probabilities were estimated with covariates set to modal values. Among 11,107 eligible patients (mean age 71.7 years), 74% received G-CSF in the first course of chemotherapy. Of all patients, 5819 (52%) received G-CSF PP, and among those not receiving G-CSF PP, only 5% received G-CSF secondary prophylaxis. The adjusted proportion using G-CSF PP increased from 6% in 2002 to 71% in 2012. During the same period, the adjusted risk of FN in the first cycle increased from 2% to 3%; the adjusted risk increased from 1.5% to 2.9% among those receiving G-CSF PP and from 2.3% to 3.5% among those not receiving G-CSF PP. The use of G-CSF PP increased substantially during the study period. Although channeling of higher-risk patients to treatment with G-CSF PP is expected, the adjusted risk of FN among patients treated with G-CSF PP tended to be lower than among those not receiving G-CSF PP.

    Chemo-induced oral mucositis (OM) is associated with significant symptoms, treatment delays and increased costs. This pilot randomised controlled trial aimed at evaluating the safety, tolerability and compliance with propolis in breast cancer patients receiving doxorubicin and cyclophosphamide, testing preliminary clinical efficacy of propolis in the prevention of OM, and prospectively evaluating the incidence of OM. Sixty patients were randomised to receive either a dry extract of propolis with 8%-12% of galangin plus mouth rinsing with sodium bicarbonate (experimental arm), or mouth rinsing with sodium bicarbonate (control arm). OM was evaluated with the NCI-CTCAE v4.0 after 5, 10, 15 and 21 days of treatment. Compliance with, tolerability of propolis and adverse events were recorded. The incidence of OM was also prospectively evaluated for 6 months. Two patients (6.7%) manifested a suspected skin reaction to propolis. No patient in the experimental arm developed OM > G1, while in the control arm OM > G1 was 16.7% (p = .02). The incidence of OM ≥ G1 at the end of cycles 2-8 was higher at the second (25%) and fifth cycles (45.8%). Propolis plus bicarbonate was safe, well tolerated and promisingly effective in the prevention of OM in patients with breast cancer. © 2017 John Wiley & Sons Ltd.

A study was conducted to assess the prognostic significances of clinico-pathologic variables and of ER, PR, p53, c-erbB2, bcl-2, or Ki-67 as markers of relapse in breast cancer patients who had received the identical adjuvant therapy at a single institution. Methods A cohort of 151 curatively resected stage III breast cancer patients (M:F = 3:148, median age 46 years who had 4 or more positive lymph nodes and received doxorubicin and cyclophosphamide followed by paclitaxel (AC/T as adjuvant chemotherapy was analyzed for clinico-pathologic characteristics including disease-free survival (DFS and overall survival (OS. Patients with positive ER and/or PR expression received 5 years of tamoxifen following AC/T. The protein expressions of biomarkers were assessed immunohistochemically. Results The median follow-up duration was 36 months, and 37 patients (24.5% experienced a recurrence. Univariate analyses indicated that the tumor size (P = 0.038 and the number of involved lymph nodes (P P = 0.013, bcl-2 positivity (P = 0.002 and low p53 expression (P = 0.032 were found to be significantly associated with a prolonged DFS. Furthermore, multivariate analysis identified 10 or more involved lymph nodes (HR 7.366; P P = 0.030, and c-erbB2 over-expression (HR 3.535; P = 0.001 as independent indicators of poorer DFS. In addition, bcl-2 expression was found to be significantly correlated with the expressions of ER and PR, and inversely correlated with the expressions of p53, c-erbB2 and Ki-67. Patients with bcl-2 expression had a significantly longer DFS than those without, even in the ER (+ subgroup. Moreover, OS was significantly affected by ER, bcl-2 and c-erbB2. Conclusion Bcl-2 is an independent prognostic factor of DFS in curatively resected stage III breast cancer patients and appears to be a useful prognostic factor in combination with c-erbB2 and the

    Purpose: Prognostic factors for locoregional failure have been poorly documented. The purpose of this retrospective review is to examine the patterns of failure of 320 patients with Stage II or III axillary node-positive breast cancer who received adjuvant chemotherapy without locoregional radiation. Methods and Materials: The records of 735 patients who were referred to the London Regional Cancer Centre between 1980 and 1989 with a diagnosis of Stage II or III breast cancer were reviewed. Three hundred and twenty patients were identified who underwent segmental mastectomy with axillary dissection or modified radical mastectomy and adjuvant chemotherapy without adjuvant locoregional radiation. Seventy-one percent of these patients had undergone a modified radical mastectomy, 40% had T1 tumors, 49% T2, and 11% T3. Resection margins were positive in 13 patients. The median number of axillary nodes removed was 11. Fifty-four percent had one to three positive axillary nodes, 27% had four to seven positive nodes, and 19% had in excess of seven positive nodes. Results: Median follow-up for the 320 patients was 77 months. One hundred and fourteen patients developed a locoregional recurrence as the site of first relapse (31 in the intact breast, 29 on the chest wall, 21 in the axilla, 22 in the supraclavicular fossa, 1 in the internal mammary chain, and 10 in multiple sites). Thirty-three percent of segmental mastectomy patients and 13% of modified radical mastectomy patients developed local recurrence. Seven percent of patients recurred in axillary or supraclavicular nodes each. Factors with regard to locoregional recurrence which on univariate analysis were significant included type of mastectomy (i.e., segmental vs. modified radical), size of primary tumor, positive resection margins, and percentage of ideal chemotherapy dose intensity ( 5 cm in diameter). Breast or chest wall radiation is recommended for these groups. Supraclavicular radiation is recommended for

    Elderly breast cancer patients are affected by poorer quality of life (QoL) compared to younger patients. Because QoL has a relevant impact on guideline-adherent treatment, elderly breast cancer patients are often undertreated, especially with regard to adjuvant chemotherapy, and overall survival is decreased. Thus, understanding the impact of chemotherapy on QoL in elderly patients is crucial. This study compared QoL in patients aged < 65 years and 65 to 70 years receiving adjuvant chemotherapy as a secondary outcome in the prospective randomized multicenter ADEBAR trial. Patients with lymph node-positive breast cancer were prospectively randomized for either sequential anthracycline-taxane or epirubicin/fluorouracil/cyclophosphamid chemotherapy (FEC) therapy. QoL was assessed at baseline (t1), before cycle 4 FEC, and cycle 5 epirubicin/cyclophosphamid-docetaxel (EC-DOC) (t2), 4 weeks after chemotherapy (t3), and 6 weeks after radiation (t4) using the European Organization for Research and Treatment for Cancer (EORTC) Quality of Life Core Questionnaire (QLQ-C30) and the Breast Cancer-Specific Module (QLQ-BR23). We compared patients aged < 65 years and 65 to 70 years with respect to QoL and discontinuation of chemotherapy. A total of 1363 patients were enrolled onto the ADEBAR trial, with 16.7% of the patients aged 65 to 70 years. In elderly patients, Eastern Cooperative Oncology Group performance status was higher and global health status and physical functioning were lower at baseline. Global health status decreased between t1 and t3 by 7 points in patients < 65 years and by 11 points in patients 65 to 70 years, and physical functioning decreased in the same period by 13.4 points in patients aged < 65 years and by 15.9 points in patients 65 to 70 years.

    The present study aimed to determine the effect of oral β-glucan on mucositis and leukopenia in 62 consecutive patients with colorectal cancer treated with an adjuvant FOLFOX-4 regimen. The patients were retrospectively evaluated in 2 groups: one group received β-glucan and the other did not (control group). Leucocytes, neutrophils, and platelets were evaluated before and 1 week after chemotherapy and oral mucositis and diarrhea were noted. Leucocyte and neutrophil counts after chemotherapy in the β-glucan group were 7,300/mm3 and 3,800/mm3, respectively, and the reductions, as compared to baseline, were not significant (p=0.673 and 0.784). The median platelet count was 264,000/mm3 after chemotherapy in the β-glucan group and the reduction, as compared to baseline, was borderline significant (p=0.048). In the control group, reduction in leucocyte, neutrophil, and platelet counts was statistically significant. Oral mucositis and diarrhea were less common in the β-glucan group. We conclude that β-glucan can be used to reduce the adverse effects of chemotherapy.

    Exercise has been reported to decrease cancer-related fatigue and to increase quality of life (QoL) in various breast cancer (BC) populations. However, studies investigating exercise during radiotherapy or resistance training are scarce. We conducted a randomized, controlled trial (BEST study) to assess the efficacy of 12-week resistance training on fatigue beyond possible psychosocial effects of a group-based intervention. One hundred sixty patients with BC stage 0-III were randomly assigned to a 12-week progressive resistance training (2 times/week) or a 12-week relaxation control (RC, 2 times/week). Both interventions were group-based. The primary end point fatigue was assessed with a 20-item multidimensional questionnaire, QoL with EORTC questionnaires. Statistical analyses were based on analysis of covariance models for the individual changes from baseline to week 13. Adherence to the intervention program as well as the completion rate (97%) for the primary outcome variable fatigue was high. In intention-to-treat analyses for the N = 155 patients, significant between-group mean differences (MD) favoring the exercise group (EX) were observed for general fatigue (P = 0.044), especially for the subscale physical fatigue [MD = -0.8; 95% confidence interval -1.5 to -0.2, P = 0.013], but not for affective (P = 0.91) or cognitive fatigue (P = 0.65). For QoL, significantly larger improvements regarding the role function (P = 0.035) and pain (P = 0.040) were noted among exercisers compared with RCs. Future perspective improved significantly stronger in the RC group compared with the EX group (P = 0.047). The 12-week resistance training program was a safe, feasible and efficacious strategy to improve cancer-related fatigue and components of QoL in BC patients during adjuvant radiotherapy. As exercise was compared with another group-based intervention, results indicate that resistance training effects on fatigue and QoL go beyond psychosocial benefits, and that the

    Breast cancer is the most frequently diagnosed cancer in women worldwide and the second cause of cancer-related mortality. A total of 20–30% of patients with early-stage breast cancer develop recurrence within the first 5 years following diagnosis. Trastuzumab significantly improves overall survival and disease-free survival (DFS) in women with human epidermal growth factor receptor 2 (HER2)-positive early and locally advanced breast cancer. This study aimed to determine the factors that affect DFS following adjuvant transtuzumab therapy. A total of 62 patients treated with trastuzumab for early and locally advanced breast cancer were included in our study. Data, including pathology, treatment and treatment outcome, rate of recurrence and laboratory tests, were retrospectively collected. There was no significant association between DFS and age, menopausal status, disease stage and hormone receptor status. The median follow-up was 48.4 months. The median DFS of patients treated with adjuvant trastuzumab was 64.1 months. In addition, the median DFS was 44.3 vs. 66.8 months in patients with platelet-lymphocyte ratio (PLR) ≤200 vs. >200, respectively (log-rank test; P=0.001), and 70 vs. 45 months in patients with eosinophil count ≤70 vs. >70×103/mm3 (log-rank test; P=0.001). Our data revealed the prognostic relevance of a decrease in the peripheral blood eosinophil count and PLR value following trastuzumab therapy in breast cancer. PLR and eosinophil count measurements are cost-effective, readily available worldwide, non-invasive and safe. Combined with other markers, such as patient age, tumor stage and tumor histology, may be effectively used for patients with breast cancer. PMID:26623060

    To evaluate the characteristics and overall survival rates of early stage cervical cancer (FIGO IB-IIA) patients who receive definitive radiation therapy and those who are prescribed adjuvant postoperative radiation and to conduct a factors analysis of the variables that affect the overall survival rates in both groups of therapy. The medical records of 85 patients with cervical cancer FIGO stages IB-IIA who were treated at the Department of Radiotherapy of Cipto Mangunkusumo Hospital were reviewed and analyzed to determine their overall survival and the factors that affected it between a definitive radiation group and an adjuvant postoperative radiation group. There were 25 patients in the definitive radiation and 60 patients in the adjuvant radiation group. The overall survival rates in the adjuvant radiation group at years one, two, and three were 96.7%, 95%, and 93.3%, respectively. Negative lymph node metastasis had an average association with overall survival (p hemoglobin (Hb) level >12 g/dl was a factor with an average association with the overall survival (p 12 g/dl tended to affect the overall survival in the definitive radiation group patients.

    Adjuvant chemotherapy has become a standard treatment of advanced rectal cancer in the West. The benefits of adjuvant chemotherapy after surgery alone have been well established. However, controversy surrounds the use adjuvant chemotherapy in patients who received preoperative chemoradiotherapy, despite it being recommended by a number of international guidelines. Results of recent multicentre randomised control trials showed no benefit of adjuvant chemotherapy in terms of survival and rates of distant metastases. However, concerns exist regarding the quality of the studies including inadequate staging modalities, out-dated chemotherapeutic regimens and surgical approaches and small sample sizes. It has become evident that not all the patients respond to adjuvant chemotherapy and more personalised approach should be employed when considering the benefits of adjuvant chemotherapy. The present review discusses the strengths and weaknesses of the current evidence-base and suggests improvements for future studies. PMID:26677436

    The main objetives of this work are to determine the tolerability of the adjuvant chemo-radiotherapy's treatment in Costa Rican patients in the Hospital San Juan de Dios, as well as to value the toxicity's level presented. A bibliographic review is realized to justify the use of this treatment's type and to determine the feasibility of its performance with the different services that are involved. The treatment's plan consisted on: after an undergoing of a gastrectomy, the patients were appointed to receive post-operative treatment combined of 5-F U plus leucovorin and radiation. The fluoracil was injected intravenous in continue infusion. The obtained results prove that the use of a lineal accelerator must be recommended as a standard treatment for this pathology by the region to treat and the complexity of the fields. The ganglion dissection performed with more frequency is inferior to one D 2, and the treatment with radiotherapy cobalt 60 and infusion al 5-F U is well tolerated with moderate-light toxicity and easily manageable [es

    Danish and Canadian randomised trials of postmastectomy radiotherapy (PMRT) have shown the importance of loco-regional control to survival in 'high risk' pre and postmenopausal women receiving adjuvant systemic therapy. The effects of radiotherapy (RT) in terms of improving survival are similar to those of systemic therapy. International consensus now supports the use of postmastectomy chest wall irradiation in women with 4 or more involved axillary nodes or primary tumour size=/> 5cm. The role of PMRT in women at intermediate risk' with 1-3 involved nodes or node negative with other risk factors is controversial. The absolute reduction in risk of loco-regional recurrence varies widely (3-23%) in trials of PMRT in women with 1-3 involved nodes receiving systemic therapy. A UK survey of clinical oncologists (Kunkler et al,The Breast 1999;8:235) showed wide variations in opinion on the use of radiotherapy in these subgroups. It is possible that while RT may confer most benefit in loco-regional control, a greater survival benefit might accrue in patients with smaller tumours and fewer involved nodes. The 2000 Oxford overview of randomised trials of postoperative RT identifies non breast cancer deaths from RT related vascular morbidity as counterbalancing the benefits of RT in reducing breast cancer mortality. With the more extensive use of potentially cardiotoxic anthracycline containing adjuvant systemic therapy there are concerns about greater cardiac morbidity in patients receiving PMRT in addition. A large randomised international trial (SUPREMO) is proposed to recruit 3500 patients with (a) 1-3 involved axillary nodes or (b) node negative with other risk factors (grade 3 or lymphovascular invasion) treated by mastectomy, axillary clearance and appropriate systemic therapy for T0-3,N0-1,MO breast cancer. The primary endpoint is overall survival. Secondary endpoints are disease free survival, quality of life, morbidity (including cardiac), cost per life year saved

  10. Synthetic Self-Adjuvanting Glycopeptide Cancer Vaccines

    2015-10-01

    Due to changes in glycosyltransferase expression during tumorigenesis, the glycoproteins of cancer cells often carry highly truncated carbohydrate chains compared to those on healthy cells. These glycans are known as tumor-associated carbohydrate antigens, and are prime targets for use in vaccines for the prevention and treatment of cancer. Herein, we review the state-of-the-art in targeting the immune system towards tumor-associated glycopeptide antigens via synthetic self adjuvanting vaccines, in which the antigenic and adjuvanting moieties of the vaccines are present in the same molecule. The majority of the self-adjuvanting glycopeptide cancer vaccines reported to date employ antigens from mucin 1, a protein which is highly over-expressed and aberrantly glycosylated in many forms of cancer. The adjuvants used in these vaccines predominantly include lipopeptide- or lipoamino acid-based TLR2 agonists, although studies investigating stimulation of TLR9 and TLR4 are also discussed. Most of these adjuvants are highly lipophilic, and, upon conjugation to antigenic peptides, provide amphiphilic vaccine molecules. The amphiphilic nature of these vaccine constructs can lead to the formation of higher-order structures by vaccines in solution, which are likely to be important for their efficacy in vivo.

    Purpose: To assess the magnitude and predictors of patient-reported fatigue among breast cancer patients receiving radiation therapy (RT). Methods and Materials: Patients receiving breast RT completed a survey querying fatigue at each weekly on-treatment visit. Patient-reported fatigue severity and interference was assessed on an ordinal scale of 0 to 4, using a validated scoring system. Baseline anxiety and depression scores were also obtained. The kinetics of mean fatigue scores per week and the maximum fatigue scores over the course of the entire treatment were assessed, and clinical predictors were identified by univariate and multivariate regression. Results: The average fatigue severity and interference scores were 0.6 and 0.46. The average fatigue scores increased to an equivalent extent from week to week, with expected increases of 0.99 in fatigue severity and 0.85 in interference over 7 weeks. Patients treated with hypofractionated RT (HF-RT) versus conventionally fractionated RT (CF-RT) had significantly fewer maximum fatigue severity or interference scores that were >2 (ie, severe or very severe; 29% vs 10% for severity, and 26% vs 8% for interference, P<.01). Age ≤45 years, presence of psychiatric/pain-related comorbidities, and baseline sadness and anxiety severity were predictive of average and maximum fatigue scores (P<.05), but variables related to treatment intensity (eg, mastectomy vs lumpectomy, chemotherapy use, radiation target volumes) and other host factors (working, children, marital status, proximity to RT facility) were not. Conclusion: Patient-reported fatigue modestly increases over RT courses, with less maximum fatigue reported with HF-RT. Younger age and baseline sadness, anxiety, and psychiatric/pain-related comorbidities are powerful predictors of fatigue, whereas other factors, such as treatment intensity, are not. Future studies will investigate interventions for patients at high risk for fatigue.

    One hundred forty-four Wistar-Furth rats in 12 therapeutic groups have been studied in a long-term comparison of the effectiveness of nonspecific immunotherapy with MER (methanol extraction residue) vs active-specific immunotherapy with neuraminidase-modified tumor cells. Six months after surgical adjuvant immunotherapy a 100% improvement in survival was achieved with MER immunotherapy compared to untreated control animals. In addition, the use of MER enhanced the value of active-specific immunotherapy where both modalities were combined in sequence. The predicted value of MER-BCG (Bacillus Calmette-Guerin) for the immunotherapy of solid tumors was borne out by these results suggesting that present ongoing clinical trials of MER as adjuvant therapy for large bowel cancer should prove to be successful if properly controlled. The pattern of survival in these experiments suggests that surgical adjuvant immunotherapy is cytostatic rather than cytocidal, and implies the need for long-term, repeated immunizations.

    On the basis of the lack of response of invasive lobular breast cancer to neoadjuvant chemotherapy, we questioned the effectiveness of adjuvant chemotherapy in relation to histology. Women with primary nonmetastatic invasive ductal or (mixed type) lobular breast cancer, aged 50-70 years, diagnosed between 1995 and 2008, were selected from the Netherlands Cancer Registry and followed until January 1, 2010. The patients were divided in two groups: one group receiving adjuvant hormonal therapy only and the other receiving adjuvant hormonal therapy in combination with adjuvant chemotherapy. In total, 19,609 patients had ductal cancer and 3685 had lobular cancer. The 10-year overall survival rate in ductal cancer when treated with hormonal therapy alone was 69%, compared with 74% with the combination therapy (P lobular cancer, 10-year survival rates were 68% after hormonal treatment alone and 66% after the combination therapy (P = 0.45). The hazard ratio (HR) for mortality in ductal cancer after combination therapy was 0.70 [95% confidence interval (CI) 0.64-0.76; P lobular cancer was 1.00 (95% CI 0.82-1.21; P = 0.97). Adjuvant chemotherapy seems to confer no additional beneficial effects in postmenopausal patients with pure or mixed type lobular breast cancer receiving hormonal therapy.

    Therapeutic cancer vaccines have shown limited clinical efficacy so far. Nevertheless, in the meantime, our understanding of immune cell function and the interactions of immune cells with growing tumors has advanced considerably. We are now in a position to invest this knowledge into the design of more powerful vaccines and therapy combinations aimed at increasing immunogenicity and decreasing tumor-induced immunosuppression. This review focuses essentially on peptide-based human vaccines. We will discuss two aspects that are critical for increasing their intrinsic immunogenicity: the selection of the antigen(s) to be targeted, and the as yet unmet need for strong adjuvants.

    The decision to treat a patient with stage II colon cancer with adjuvant chemotherapy can be challenging. Although the benefit of treatment is clear in most patients with stage III disease, the decision to provide chemotherapy after surgical resection in stage II disease must be made on an individual basis. Several trials have demonstrated the small but absolute benefits of receiving adjuvant chemotherapy for stage II colon cancer for disease-free survival and overall survival. In an attempt to better understand the role of chemotherapy, several studies were performed that identified high-risk characteristics that can be used prognostically and predictively to aid in the clinical decision making process. ASCO, the National Comprehensive Cancer Network, and the European Society of Medical Oncology have published guidelines describing these high-risk characteristics. Since then, several other molecular markers have emerged that may offer more information on a given patient's risk for recurrence. The decision to treat a patient with stage II colon cancer must be made on an individual basis, considering the risks and benefits of treatment. In this short review, we will present the available evidence and offer possible directions for future study.

    As triple-negative breast cancers are associated with earlier recurrences and poorer survival, optimal treatment of early-stage breast cancer is essential. Several retrospective studies in triple-negative breast cancer have reported conflicting results in overall survival in patients receiving neoadjuvant or adjuvant systemic therapy. This study aims to analyze outcomes of adjuvant versus neoadjuvant in patients with early-stage triple-negative breast cancer with and without BRCA germline mutations. Patients with stage I or II triple-negative breast cancer who had BRCA testing were identified from a prospective cohort study of 4027 patients. Clinical, demographic, genetic test results, chemotherapy, recurrence, and survival data were analyzed. Overall survival and disease-free survival were estimated using the Kaplan-Meier method. 319 patients with stage I and II triple-negative breast cancer who met eligibility criteria were included in the analysis. 187 received adjuvant chemotherapy (58.6%) and 132 received neoadjuvant chemotherapy (41.4%). 135 were BRCA positive (42.3%) and 184 were BRCA negative (57.7%). There was no significant association between overall survival or disease-free survival and treatment with neoadjuvant versus adjuvant in the overall cohort. Furthermore, there were no significant differences between patient subgroups (neoadjuvant BRCA positive, neoadjuvant BRCA negative, adjuvant BRCA positive, and adjuvant BRCA negative) with respect to either overall survival or disease-free survival. Neoadjuvant versus adjuvant with standard anthracycline- and taxane-containing regimens results in similar disease-free survival and overall survival among patients with stage I and II triple-negative breast cancer regardless of BRCA status. Further studies are needed to evaluate whether similar results are observed with newer agents.

    Full Text Available OBJECTIVE: We examined our database of patients undergoing radical cystectomy (RC with orthotopic neobladder (NB to determine whether adjuvant chemotherapy in this group is safe. MATERIALS AND METHODS: We performed a retrospective analysis of patients who underwent radical cystectomy and urinary diversion between 1992 and 2004. Relevant clinical and therapeutic data were entered into a database. High-risk bladder cancer patients who underwent NB were identified. They were stratified into 2 groups, those who received adjuvant chemotherapy and those who did not. The incidence of complications between the 2 groups was analyzed and compared. RESULTS: Over the 12-year period, 136 patients underwent RC and NB construction for bladder cancer. Of these, 83 patients were at high risk for recurrence. Nineteen patients received adjuvant chemotherapy and 64 did not. The complication rate in the adjuvant chemotherapy group was 53% and it was 23% in those who did not receive chemotherapy. There were no perioperative or treatment related death. There were 2 patients with grade 4 toxicity in the adjuvant chemotherapy group. There was a statistical difference between these two groups with regard to the incidence of complications. However, none of these complications was life-threatening, required only conservative treatment and caused no long-term disability. CONCLUSIONS: Adjuvant chemotherapy is a safe treatment for patients undergoing RC and NB substitution. Hence, the option of orthotopic NB should not be denied in selected bladder cancer patients with high risk for recurrent disease.

    Currently available data suggest that delaying the start of adjuvant chemotherapy in colon cancer patients has a detrimental effect on survival. We analysed which factors impact on the timing of adjuvant chemotherapy and evaluated the influence on overall survival (OS). Stage III colon cancer patients who underwent resection and received adjuvant chemotherapy between 2008 and 2013 were selected from the Netherlands Cancer Registry. Timing of adjuvant chemotherapy was subdivided into: ⩽ 4, 5-6, 7-8, 9-10, 11-12 and 13-16 weeks post-surgery. Multivariable regressions were performed to assess the influence of several factors on the probability of starting treatment within 8 weeks post-surgery and to evaluate the association of timing of adjuvant chemotherapy with 5-year OS. 6620 patients received adjuvant chemotherapy, 14% commenced after 8 weeks. Factors associated with starting treatment after 8 weeks were older age (Odds ratio (OR) 65-74 versus colon cancer patients within 8 weeks post-surgery. Copyright © 2015 Elsevier Ltd.

    The role of adjuvant chemotherapy in patients with stage II colon cancer remains to be elucidated and its use varies between patients and institutions. Currently, clinical guidelines suggest discussing adjuvant chemotherapy for patients with high-risk stage II disease in the absence of conclusive randomized controlled trial data. To further investigate this relationship, the objective of the current study was to determine whether an association exists between overall survival (OS) and adjuvant chemotherapy in patients stratified by age and pathological risk features. Data from the National Cancer Data Base were analyzed for demographics, tumor characteristics, management, and survival of patients with stage II colon cancer who were diagnosed from 1998 to 2006 with survival information through 2011. Pearson Chi-square tests and binary logistic regression were used to analyze disease and demographic data. Survival analysis was performed with the log-rank test and Cox proportional hazards regression modeling. Propensity score weighting was used to match cohorts. Among 153,110 patients with stage II colon cancer, predictors of receiving chemotherapy included age clinically relevant OS was associated with the receipt of adjuvant chemotherapy in all patient subgroups regardless of high-risk tumor pathologic features (poor or undifferentiated histology, colon cancer evaluated to date, improved OS was found to be associated with adjuvant chemotherapy regardless of treatment regimen, patient age, or high-risk pathologic risk features.

    With increasing prevalence of diabetes mellitus and colon cancer, the number of patients suffering from both diseases is growing, and physicians are being faced with complicated treatment decisions. To investigate the association between diabetes and treatment/course of stage III colon cancer and the association between colon cancer and course of diabetes. Additional information was collected from the medical records of all patients with both stage III colon cancer and diabetes ( n =201) and a random sample of stage III colon cancer patients without diabetes ( n =206) in the area of the population-based Eindhoven Cancer Registry (1998-2007). Colon cancer patients without diabetes were more likely to receive adjuvant chemotherapy compared with diabetic colon cancer patients (OR 1.8; 95% CI 1.2-2.7). After adjustment for age, this difference was borderline significant (OR 1.6; 95% CI 1.0-2.6). Diabetic patients did not have: significantly more side-effects from surgery or adjuvant chemotherapy; more recurrence from colon cancer; significantly shorter time interval until recurrence; or a poorer disease-free survival or overall survival. Age and withholding of adjuvant chemotherapy were most predictive of all-cause mortality. After colon cancer diagnosis, the dose of antiglycaemic medications was increased in 22% of diabetic patients, resulting in significantly lower glycaemic indexes than before colon cancer diagnosis. Since diabetic patients did not have more side-effects of adjuvant chemotherapy, and adjuvant chemotherapy had a positive effect on survival for both patients with and without diabetes, diabetes alone should not be a reason for withholding adjuvant chemotherapy.

    IMPORTANCE There is an immediate need to develop local intraoperative adjuvant treatment strategies to improve outcomes in patients with cancer who undergo head and neck surgery. OBJECTIVES To determine the safety of photodynamic therapy with 2-(1-hexyloxyethyl)-2-devinyl pyropheophorbide-a (HPPH) in combination with surgery in patients with head and neck squamous cell carcinoma. DESIGN, SETTING, AND PARTICIPANTS Nonrandomized, single-arm, single-site, phase 1 study at a comprehensive cancer center among 16 adult patients (median age, 65 years) with biopsy-proved primary or recurrent resectable head and neck squamous cell carcinoma. INTERVENTIONS Intravenous injection of HPPH (4.0 mg/m2), followed by activation with 665-nm laser light in the surgical bed immediately after tumor resection. MAIN OUTCOMES AND MEASURES Adverse events and highest laser light dose. RESULTS Fifteen patients received the full course of treatment, and 1 patient received HPPH without intraoperative laser light because of an unrelated myocardial infarction. Disease sites included larynx (7 patients), oral cavity (6 patients), skin (1 patient), ear canal (1 patient), and oropharynx (1 patient, who received HPPH only). The most frequent adverse events related to photodynamic therapy were mild to moderate edema (9 patients) and pain (3 patients). One patient developed a grade 3 fistula after salvage laryngectomy, and another patient developed a grade 3 wound infection and mandibular fracture. Phototoxicity reactions included 1 moderate photophobia and 2 mild to moderate skin burns (2 due to operating room spotlights and 1 due to the pulse oximeter). The highest laser light dose was 75 J/cm2. CONCLUSIONS AND RELEVANCE The adjuvant use of HPPH-photodynamic therapy and surgery for head and neck squamous cell carcinoma seems safe and deserves further study. PMID:23868427

    Full Text Available Abstract Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0, and to obtain the utility value by the standard gamble (SG and visual scale (VS methods. Total medical cost was assessed from the (National Health Insurance NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

    Recently, randomized trials revealed that trastuzumab as adjuvant treatment was effective in human epidermal growth factor receptor 2 (HER2)-positive breast cancer patients. Safety information on adjuvant trastuzumab use in Japanese patients, especially cardiac toxicity data, is needed. We retrospectively reviewed 48 patients with early-stage HER2-positive breast cancer who were treated with curative surgery and adjuvant trastuzumab at the National Cancer Center Hospital East (Kashiwa, Japan). The cardiac safety as well as the short-term efficacy of trastuzumab were evaluated. The median age of the patients was 54 years. All patients received adjuvant or neoadjuvant cytotoxic chemotherapy. Twenty-seven patients (56%) received adjuvant radiation therapy. Forty-four patients (92%) received trastuzumab without concurrent cytotoxic chemotherapy and 4 patients (8%) on taxanes received trastuzumab concurrently. Twenty-five patients completed 1 year of trastuzumab treatment and 5 patients completed 2 years of trastuzumab treatment. Nine patients discontinued trastuzumab treatment, because of progressive disease (1 patient), decrease in left ventricular ejection fraction (LVEF; 2 patients), patient's refusal (4 patients), and other reasons (2 patients). There were five cardiac events. A decrease in LVEF to less than 50% was seen in 2 patients. The relationship between trastuzumab treatment and the cardiac events was unclear in 3 patients. The median follow-up time was 21.2 months. The disease-free survival (DFS) was 97.5% at 1 year and 92.9% at 2 years. The incidence of cardiac events caused by trastuzumab treatment was low in our analysis. Adjuvant trastuzumab treatment for up to at least 1 year should be safe for Japanese breast cancer patients.

    Adjuvant chemotherapy offers a survival benefit to a number of staging scenarios in non-small-cell lung cancer. Variable recovery from lung cancer surgery may delay a patient's ability to tolerate adjuvant chemotherapy, yet the urgency of chemotherapy initiation is unclear. To assess differences in survival according to the time interval between non-small-cell lung cancer resection and the initiation of postoperative chemotherapy to determine the association between adjuvant treatment timing and efficacy. This retrospective observational study examined treatment-naive patients with completely resected non-small-cell lung cancer who received postoperative multiagent chemotherapy between 18 and 127 days after resection between January 2004 and December 2012. The study population was limited to patients with lymph node metastases, tumors 4 cm or larger, or local extension. Patients were identified from the National Cancer Database, a hospital-based tumor registry that captures more than 70% of incident lung cancer cases in the United States. The association between time to initiation of adjuvant chemotherapy and survival was evaluated using Cox models with restricted cubic splines. Adjuvant chemotherapy administered at different time points after surgery. Effectiveness of adjuvant chemotherapy according to time to initiation after surgery. A total of 12 473 patients (median [interquartile range] age, 64 [57-70] years) were identified: 3073 patients (25%) with stage I disease; 5981 patients (48%), stage II; and 3419 patients (27%), stage III. A Cox model with restricted cubic splines identified the lowest mortality risk when chemotherapy was started 50 days postoperatively (95% CI, 39-56 days). Initiation of chemotherapy after this interval (57-127 days; ie, the later cohort) did not increase mortality (hazard ratio [HR], 1.037; 95% CI, 0.972-1.105; P = .27). Furthermore, in a Cox model of 3976 propensity-matched pairs, patients who received chemotherapy during

  19. Adjuvant Therapy for Stage II Colorectal Cancer: Who and with What?

    2006-06-01

    The role of adjuvant chemotherapy for patients with stage II colon adenocarcinoma remains controversial. The high surgical cure rate for patients with "low-risk" stage II colon cancer, ranging from 75% to 80%, and the available clinical trials and meta-analyses provide conflicting recommendations for or against adjuvant chemotherapy for this group of patients. For fit "high-risk" stage II patients with clinical obstruction or perforation at presentation, in which the 5-year survival rate is 60% to 70%, there is little controversy, as these patients are routinely treated with adjuvant chemotherapy. Other potential high-risk factors, including high histologic grade, microsatellite instability, and loss of 18q, have yet to be validated in prospective trials. Patients with fewer than 12 regional lymph nodes identified in the surgical specimen have a statistically unclear risk of lymph node involvement. These patients may have stage III disease and should receive adjuvant therapy. The decision to use adjuvant chemotherapy to treat low-risk stage II colon cancer patients (no obstruction or perforation) should be an informed decision weighing the magnitude of a net 2% to 5% survival benefit, a 0.5% to 1.0% risk of mortality with chemotherapy in addition to 6 months of chemotherapy-related toxicities, other coexisting patient morbidities, and the anticipated life expectancy of each patient. As adjuvant chemotherapy is therapy addressing local or metastatic microscopic disease, and the effectiveness of systemic and biologically targeted therapy for advanced macroscopic colon cancer continues to improve rapidly, it remains to be determined by clinical trials whether therapies including newer agents such as cetuximab and bevacizumab administered in the adjuvant setting may affect survival for stage II cancer patients.

    Patients irradiated for left-sided breast cancer have higher incidence of cardiovascular disease than those receiving irradiation for right-sided breast cancer. Most abnormalities were in the left anterior descending (LAD) coronary artery territory. We analyzed the relationships between preoperative examination results and irradiation dose to the LAD artery in patients with left-sided breast cancer. Seventy-one patients receiving breast radiotherapy were analyzed. The heart may rotate around longitudinal axis, showing either clockwise or counterclockwise rotation (CCWR). On electrocardiography, the transition zone (TZ) was judged in precordial leads. CCWR was considered to be present if TZ was at or to the right of V3. The prescribed dose was 50 Gy in 25 fractions. The maximum (Dmax) and mean (Dmean) doses to the LAD artery and the volumes of the LAD artery receiving at least 20 Gy, 30 Gy and 40 Gy (V20Gy, V30Gy and V40Gy, respectively) were significantly higher in CCWR than in the non-CCWR patients. On multivariate analysis, TZ was significantly associated with Dmax, Dmean, V20Gy, V30Gy, and V40Gy. CCWR is a risk factor for high-dose irradiation to the LAD artery. Electrocardiography is useful for evaluating the cardiovascular risk of high-dose irradiation to the LAD artery.

    Therapeutic touch (TT) is a non-invasive commonly used complementary therapy. TT is based on the use of hand movements and detection of energy field congestion to correct imbalances. Improvement in subjective symptoms in a variety of clinical trials has been seen with TT. The effect of TT during radiotherapy for breast cancer is unknown. Women undergoing adjuvant radiation for Stage I/II breast cancer post conservative surgery were recruited for this cohort study. TT treatments were administered three times per week following radiation therapy. Feasibility was defined as an a priori threshold of 15 of 17 patients completing all TT treatments. The preventive effectiveness of TT was evaluated by documenting the 'time to develop' and the 'worst grade of radiation' dermatitis. Toxicity was assessed using NCIC CTC V3 dermatitis scale. Cosmetic rating was performed using the EORTC Breast Cosmetic Rating. The quality of life, mood and energy, and fatigue were assessed by EORTC QLQ C30, POMS, and BFI, respectively. The parameters were assessed at baseline, and serially during treatment. A total of 49 patients entered the study (17 in the TT Cohort and 32 in the Control Cohort). Median age in TT arm was 63 years and in control arm was 59 years. TT was considered feasible as all 17 patients screened completed TT treatment. There were no side effects observed with the TT treatments. In the TT Cohort, the worst grade of radiation dermatitis was grade II in nine patients (53%). Median time to develop the worst grade was 22 days. In the Control Cohort, the worst grade of radiation dermatitis was grade III in 1 patient. However, the most common toxicity grade was II in 15 patients (47%). Three patients did not develop any dermatitis. Median time to develop the worst grade in the control group was 31 days. There was no difference between cohorts for the overall EORTC cosmetic score and there was no significant difference in before and after study levels in quality of life, mood

    Recently we have shown that NSC-631570 (Ukrain) is a safe and effective drug in the treatment of unresectable pancreatic cancer. The aim of this study was to determine the effectiveness of the combined treatment with Gemcitabine and NSC-631570 in the adjuvant treatment of resected advanced pancreatic cancer. 30 patients received adjuvant chemotherapy following surgical resection for pancreatic cancer. Chemotherapy consisted of Gemcitabine according to the Burris-protocol with weekly infusions of 1000 mg/sqm. Immediately following Gemcitabine infusion 20mg of NSC-631570 were administered intravenously over 15 minutes. WHO grade II toxicities were observed in 53%, no WHO grade III or IV toxicities occurred. In 80% of the patients recurrence of the disease was observed. The relapse-free survival time was 21.7 months. The actuarial survival rates were 86.7% after one year, 76.6% after two years, 46.7% after three years and 23.3% after five years. The median survival time according to Kaplan-Meier regression analysis was 33.8 months. Adjuvant chemotherapy in advanced stages of pancreatic cancer using the combination of Gemcitabine and NSC-631570 is a safe treatment and seems to lead to a prolonged survival. Although further investigation is needed to confirm these results, the combined treatment of Gemcitabine and NSC-631570 is a promising therapy for the adjuvant treatment of resectable advanced pancreatic cancer.

    Full Text Available Although rare, clinicians and patients must be aware that therapy related malignancies, specifically acute myeloid leukemia (AML, can occur as a complication of adjuvant chemotherapy for breast cancer. Vigilance for signs and symptoms is appropriate. AML with t (8;16 is a specific translocation leading to formation of a fusion protein (MYST3/CREBBP. The MYST3/CREBBP AML tends to develop within 2 years of adjuvant chemotherapy, especially for breast cancer, without preceding myelodysplasia. It usually presents with disseminated intravascular coagulation and osteolytic lesions and has a poor prognosis despite aggressive resuscitation and therapy. With the increasing use of adjuvant chemotherapy for breast cancer, we are seeing a definite increase in the incidence of therapy related myelodysplastic syndromes and AML. One must keep this complication in mind while counseling and following up breast cancer patients who have received adjuvant chemotherapy. New osteolytic bone lesions in a patient with history of breast cancer do not necessarily mean metastatic disease and should be fully evaluated.

    The standard treatment for hormone-receptor positive, postmenopausal early breast cancer patients is 5 years of adjuvant endocrine therapy. Previous studies demonstrate that prolonging adjuvant endocrine therapy may improve disease-free survival. However, endocrine therapy is known for its adverse events, which may negatively affect Quality of Life (QoL). The aim of this study is to assess the impact of extended adjuvant endocrine therapy on long-term QoL outcomes. 471 patients selected from the IDEAL trial were invited to complete a questionnaire 1-1.5 years after starting with extended therapy. The questionnaire consisted of the EORTC QLQ-C30 and QLQ-BR23 questionnaires. Mean QoL outcomes were compared with EORTC reference values for stage I and II breast cancer patients and the general population. Furthermore, QoL outcomes were compared between different treatment regimens. A difference of eight points was considered clinically relevant. IDEAL patients receiving extended adjuvant endocrine therapy have significantly and clinically relevant better global QoL compared with reference values for stage I and II breast cancer patients (79.6 versus 64.6; p treatment regimens prior to extended adjuvant endocrine therapy, differences were only found on specific QoL domains (e.g. arm symptoms). Breast cancer patients on extended adjuvant endocrine therapy have significantly and clinically relevant better global QoL compared with other stage I-II breast cancer patients and the general population, 6-8.5 years after diagnosis.

    The purpose of this study was to evaluate the impact of radiotherapy in terms of feasibility and activity in the patients aged > or = 75 with advanced rectal cancer. From January 2002 to December 2006, 41 consecutive patients (27 men and 14 women) aged > or = 75 received radiotherapy for local advanced rectal cancer, 9 in a pre-operative and 22 in a post-operative setting. Sixteen patients received concomitant chemotherapy. Variables considered were age, co-morbidities, evaluated according to the adult co-morbidity evaluation index (ACE-27), surgery versus no surgery, and timing of radiotherapy. The median age was 80.5 years (range 75-90). A total of 19.5% of the patients had no co-morbidity, 48.8% mild, 17.1% moderate, and 14.6% had severe co-morbidities. Thirty-nine subjects (95.1%) were submitted to surgery. All patients but one completed the planned radiation schedule. At a median follow-up of 23.1 months, the 2- and 4-year overall survival rates were 71.8% and 61.6%, respectively. There was a better survival for patients with no or mild co-morbidities (p=0.002) and a good performance status (p=0.003). The cancer-free survival at 2 and 4 years was 78.9% and 26.4%, respectively. No difference in acute and late toxicity rates was found between patients with different ACE-27 indexes. We conclude that compliance with radiotherapy is good and rate of toxicity is acceptable in elderly patients. Patients with no or mild co-morbidities have a significantly better survival. Increasing severity of co-morbidity may sufficiently shorten remaining life expectancy to cancel gains with adjuvant radiotherapy. Further prospective trials are needed to confirm these results.

    This paper presents long-term results from a randomized trial of pre- or postoperative megavoltage radiation therapy versus surgery alone in pre- and postmenopausal women with operable breast cancer. Treatment outcome after relapse among patients who developed loco-regional recurrences was also analyzed. A total of 960 patients were included in the trial. The mean follow-up was 16 years (range: 13-19 years). The radiation therapy was individually planned. It included the chest wall (and the breast in the preoperative cases) and the regional lymph nodes. The tumor dose was 45 Gy/5 weeks. No adjuvant systemic therapy was used. The results showed a significant benefit with radiation therapy in terms of recurrence-free survival during the entire follow-up period. There was also an overall survival difference - corresponding to 16% reduction of deaths - in favour of the irradiated patients which, however, was not statistically significant (p=0.09). Among those 169 patients who developed loco-regional recurrences long-term control was only achieved in about one-third of the cases. This figure was similar among those who had received adjuvant radiation therapy (34%) compared to those initially treated with surgery alone (32%). This implied that the overall proportion of patients who eventually developed uncontrolled local disease was significantly higher among those initially allocated to surgery alone (16%) compared to those allocated to pre- or postoperative radiation therapy (6%, p<0.01). These results suggest that local undertreatment may be deleterious in subgroups of patients. (author) 5 tabs

    This work establishes the associated factors to the early recurrence of gastric cancer in the patients who have received adjuvant chemoradiation in the Hospital Dr. R. A. Calderon Guardia. It was determined if the personal factors such as age and gender influence in the evolution of theses cases. The importance of characteristics of the tumour as T, N, location, Borrmann type and histological type in the evolution of the disease was estimated, too. It mentions the epidemiological characteristics of patients who have received the therapy and describes the toxicity of the treatment. A retrospective-descriptive method was utilized and the clinical records of the patients of the hospital with gastric cancer diagnosis were reviewed. These patients were surgery candidates and then they received adjuvant ia with chemoradiation from 2003 and with at lest 12 months of monitoring. The main conclusions are: Hospital Calderon Guardia practices the surgery with D2 ganglionar dissection as treatment of potentially curable gastric cancer. The population with gastric cancer has a predominance of men and people between seventh and fifth decade of life. The studied series had a recurrent tendency for female sex. To major pT (pathologic size) of the tumour there is more risks of recurrence. The pattern of regional recurrence in peritoneal carcinomathosis shape is which has a tendency to predominate after the adjuvant treatment in gastric cancer. The toxicity of the adjuvant treatment for gastric cancer is not severe and it is manageable without necessity of suspend the treatment in the majority of the cases [es

    The role of adjuvant chemotherapy and the value of molecular biomarkers in bladder cancer have not been determined. We aimed to assess the predictive and prognostic values of excision repair cross-complementation 1 (ERCC1) in identifying appropriate patients who may potentially benefit from adjuvant chemotherapy for bladder cancer. A retrospective analysis was performed on 93 patients with completely resected transitional cell carcinoma of the bladder. ERCC1 expression was assessed by immunohistochemistry. ERCC1 expression was analyzed in 57 patients treated with adjuvant gemcitabine plus cisplatin chemotherapy and 36 who were not treated. Among 93 patients, ERCC1 expression was positive in 54 (58.1%) and negative in 39 (41.9%). ERCC1 positivity was significantly associated with longer survival (adjusted hazard ratio for death, 0.12, 95% confidence interval [CI] 0.014-0.99; P = 0.049) in the group without adjuvant chemotherapy while ERCC1 positivity was associated with shorter survival among patients who have received adjuvant chemotherapy (adjusted hazard ratio for death, 2.64; 95% CI 1.01-6.85; P = 0.047). Therefore, clinical benefit from adjuvant chemotherapy was associated with ERCC1 negativity as measured by overall survival (test for interaction, P = 0.034) and by disease-free survival (test for interaction, P = 0.20). Among patients with completely resected transitional cell carcinoma of the bladder, those with ERCC1-negative tumors seemed to benefit more from adjuvant gemcitabine plus cisplatin chemotherapy than those with ERCC1-positive tumors. Future prospective, randomized studies are warranted to confirm our findings

    1990-06-01

    From 1971 through 1984, 320 women underwent radical hysterectomy as primary therapy of stage IB and IIA cervical cancer. Two hundred forty-eight patients (78%) were treated with surgery alone and 72 patients (22%) received adjuvant postoperative external-beam radiotherapy. Presence of lymph node metastasis, large lesion (greater than 4 cm in diameter), histologic grade, race (noncaucasian), and age (greater than 40 years) were significant poor prognostic factors for the entire group of patients. Patients treated with surgery alone had a better disease-free survival than those who received combination therapy (P less than 0.001). However, patients receiving adjuvant radiation therapy had a higher incidence of lymphatic metastases, tumor involvement of the surgical margin, and large cervical lesions. Adjuvant pelvic radiation therapy did not improve the survival of patients with unilateral nodal metastases or those who had a large cervical lesion with free surgical margins and the absence of nodal involvement. Radiation therapy appears to reduce the incidence of pelvic recurrences. Unfortunately, 84% of patients who developed recurrent tumor after combination therapy had a component of distant failure. The incidence of severe gastrointestinal or genitourinary tract complications was not different in the two treatment groups. However, the incidence of lymphedema was increased in patients who received adjuvant radiation therapy. Although adjuvant radiation therapy appears to be tolerated without a significant increase in serious complications, the extent to which it may improve local control rates and survival in high-risk patients appears to be limited. In view of the high incidence of distant metastases in high-risk patients, consideration should be given to adjuvant systemic chemotherapy in addition to radiation therapy.

    The purpose of this study is to evaluate the treatment outcomes of adjuvant radiotherapy using vaginal brachytherapy (VB) with a lower dose per fraction and/or external beam radiotherapy (EBRT) following surgery for patients with stage I endometrial carcinoma. The subjects were 43 patients with the International Federation of Gynecology and Obstetrics (FIGO) stage I endometrial cancer who underwent adjuvant radiotherapy following surgery between March 2000 and April 2014. Of these, 25 received postoperative VB alone, while 18 received postoperative EBRT to the whole pelvis; 3 of these were treated with EBRT plus VB. The median EBRT dose was 50.0 Gy (45.0–50.4 Gy) and the VB dose was 24 Gy in 6 fractions. Tumor dose was prescribed at a depth of 5 mm from the cylinder surface and delivered twice per week. The median follow-up period for all patients was 57 months (range, 9 to 188 months). Five-year disease-free survival (DFS) and overall survival (OS) for all patients were 92.5% and 95.3%, respectively. Adjuvant radiotherapy was performed according to risk factors and stage IB, grade 3 and lymphovascular invasion were observed more frequently in the EBRT group. Five-year DFS for EBRT and VB alone were 88.1% and 96.0%, respectively (p = 0.42), and 5-year OS for EBRT and VB alone were 94.4% and 96%, respectively (p = 0.38). There was no locoregional recurrence in any patient. Two patients who received EBRT and 1 patient who received VB alone developed distant metastatic disease. Two patients who received EBRT had severe complications, one each of grade 3 gastrointestinal complication and pelvic bone insufficiency fracture. Adjuvant radiotherapy achieved high DFS and OS with acceptable toxicity in stage I endometrial cancer. VB (with a lower dose per fraction) may be a viable option for selected patients with early-stage endometrial cancer following surgery.

    We aimed to present the clinical outcomes of adjuvant concurrent chemoradiotherapy (CCRT) with low-dose daily cisplatin regimen compared to the conventional 5-fluorouracil (5-FU)-based regimen for extrahepatic bile duct cancer (EHBDC). From October 1994 to April 2013, 41 patients received adjuvant CCRT with low-dose daily regimen or 5-FU-based regimens. Nineteen patients received low-dose of cisplatin just before every delivery of radiation therapy, and 21 patients received two cycles of 5-FU-based regimen during radiotherapy. We compared the clinical outcomes between two adjuvant CCRT regimens. Adjuvant CCRT with low-dose daily cisplatin showed comparable toxicity profiles compared with that of a 5-FU-based regimen. The median follow-up time was 33 months (range, 5-205), and the 5-year overall survival (OS), locoregional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) were 34.2, 50.8, and 49.7%, respectively. Univariable analyses showed no significant differences in OS, LRRFS, and DMFS between the groups with two regimens. In multivariable analyses, chemotherapeutic regimen was a significant prognostic factor for OS, favoring the low-dose daily cisplatin regimen (HR = 2.491, p = 0.036) over 5-FU-based regimen, though not for LRRFS (p = 0.642) and DMFS (p = 0.756). Adjuvant CCRT with low-dose daily cisplatin regimen showed acceptable toxicities and survivals compared to those of the 5-FU-based regimen. Low-dose daily cisplatin can be one of the feasible regimens for adjuvant CCRT for EHBDC.

This study aims to assess the QoL of premenopausal Chinese breast cancer women after receiving adjuvant chemotherapy.Patients and methods: Eligibility criteria included stage I–III breast cancer, premenopausal and age ≤45 years at cancer diagnosis and having received adjuvant chemotherapy within 3–10 years before entry to the present study. Patients’ background demographics at the time of breast cancer diagnosis, together with tumor characteristics and anticancer treatments, were collected. At the time of study entry, the menopausal status based on menstrual history, body mass index, and QoL (assessed using Functional Assessment of Cancer Therapy-Breast +4 were recorded.Results: Two hundred and eighty patients were recruited. Ninety-five patients (33.9% underwent breast-conserving surgery, and nearly all (98.6% underwent axillary dissection. For adjuvant therapies, 249 patients (88.9% received anthracycline-containing chemotherapy and 79 (28.2% received taxane-containing chemotherapy, while 68 (24.3% received both. One hundred and eighty six patients (66.4% received adjuvant radiotherapy, and 214 (76.4% received adjuvant tamoxifen. The median time from breast cancer diagnosis to study entry was 5.01 years. QoL assessment at study entry revealed that older patients had worse social well-being (SWB; mean scores for age ≤40, 41–45, 46–50 and >50 years were 22.0, 19.3, 19.1 and 18.1, respectively

    Imatinib mesylate is the standard treatment of chronic myeloid leukemia (CML). Despite imatinib is being used in the treatment of other malignancies as well, its potential role on de novo tumor growth is not known. Secondary malignancies are rarely seen in patients with CML and particularly in those receiving imatinib. Here, we present a CML patient taking imatinib therapy that was diagnosed to have breast cancer and received adjuvant chemo-and radiotherapy with imatinib. We tried to explain co-occurrence of these rare events by probable pathogenetic mechanisms.

    Background: Multiple clinical trials have demonstrated the benefits of adjuvant 5-fluorouracil-based chemotherapy for patients with resectable colon cancer (CC), especially in stage III. Aim: To describe the clinical characteristics of a cohort of CC patients treated at a single university hospital in Chile since 2002, and to investigate if chemotherapy had an effect on survival rates. Material and Methods: Review of a tumor registry of the hospital. Medical records of patients with CC treated between 2002 and 2012 were reviewed. Death certificates from the National Identification Service were used to determine mortality. Overall survival was described using the Kaplan-Meier method. A multivariate Cox proportional hazard regression model was also used. Results: A total of 370 patients were treated during the study period (202 in stage II and 168 in stage III). Adjuvant chemotherapy was administered to 22 and 70% of patients in stage II and III respectively. The median follow-up period was 4.6 years. The 5-year survival rate for stage II patients was 79% and there was no benefit observed with adjuvant chemotherapy. For stage III patients, the 5-year survival rate was 81% for patients who received adjuvant chemotherapy, compared to 56% for those who did not receive chemotherapy (hazard ratio (HR): 0.29; 95% confidence interval (CI): 0.15-0.56). The benefit of chemotherapy was found to persist after adjustment for other prognostic variables (HR: 0.47; 95% CI: 0.23-0.94).Conclusions: Patients with colon cancer in stage III who received adjuvant chemotherapy had a better overall survival

    Full Text Available Abstract Objective It was aimed to review the literature and make a meta-analysis of the trials on both upfront, switching, and sequencing anastrozole in the adjuvant treatment of early breast cancer. Methods The PubMed, ClinicalTrials.gov and Cochrane databases were systematically reviewed for randomized-controlled trials comparing anastrozole with tamoxifen in the adjuvant treatment of early breast cancer. Results The combined hazard rate of 4 trials for event-free survival (EFS was 0.77 (95%CI: 0.70–0.85 (P P P Conclusion Anastrozole appears to have superior efficacy than tamoxifen in the adjuvant hormonal treatment of early breast cancer. Until further clinical evidence comes up, aromatase inhibitors should be the initial hormonal therapy in postmenopausal early breast cancer patients and switching should only be considered for patients who are currently receiving tamoxifen.

    We attempted to determine the preferences of women regarding the benefits they considered necessary to make adjuvant therapy worthwhile, and to compare preferences for adjuvant endocrine therapy, chemotherapy, and trastuzumab therapy. We also investigated the effect of information about cost on women's treatment preferences. Consecutive women who had a medical examination at the Breast Clinic, Ota General Hospital, were included in our study. We collected a questionnaire from a total of 365 women; 297 completed responses were included in the study. Among 297 women, 105 had breast cancer that had been treated and 192 did not have breast cancer; 38% of women judged that a 5% or less gain in the probability of survival was sufficient to make endocrine therapy worthwhile; 28% of participants judged that chemotherapy was worthwhile; 24% of participants judged that trastuzumab therapy was worthwhile. Women indicated that they were more likely to receive adjuvant endocrine therapy than chemotherapy or trastuzumab therapy, for the same gains in the probability of survival. Cost information about treatments did not affect women's treatment preferences. Younger women tended to judge improvements in survival sufficient to make adjuvant endocrine and chemotherapy worthwhile, as compared to older women. The comparisons were statistically significant in the 10 and 20% categories for endocrine therapy and chemotherapy. Women prefer endocrine therapy to chemotherapy or trastuzumab therapy, given the same projected treatment benefits. Younger women prefer both chemotherapy and endocrine therapy as compared with older woman.

    Neo-adjuvant chemo-radiation is the standard of care for patients with locally advanced rectal carcinoma. The aim of the present paper is to evaluate the relationship of the baseline serologic concentration of the carcinoembryonic antigen with the outcome. Data sources included MEDLINE and Web of Science databases. A systematic search of the databases by a predefined criterion has been conducted. Chemo-radiation followed by surgical resection of rectal tumors was the intervention of interest. From selected studies, the relationships between carcinoembryonic antigen and pathologic complete response, disease-free survival and overall survival were assessed. Carcinoembryonic antigen correlated significantly and inversely with the rate of pathologic complete responses (OR 2.00). Similar to this relationship, a low baseline carcinoembryonic antigen concentration was associated with a better disease-free survival (OR 1.88) and a better overall survival (OR 1.85). Heterogeneity of studies and publication bias were considerable in evaluating the relationship of baseline carcinoembryonic antigen and pathologic complete response. Baseline carcinoembryonic antigen should be regarded as a predictor of outcome of patients undergoing neo-adjuvant chemo-radiation. A calibration of the cutoff value from 5 to 3 ng/ml appears more appropriate to this patient population and should be evaluated in prospective trials.

    Full Text Available Abstract Background Dendritic cells (DCs have the potential for cancer immunotherapy due to their ability to process and present antigens to T-cells and also in stimulating immune responses. However, DC-based vaccines have only exhibited minimal effectiveness against established tumours in mice and humans. The use of appropriate adjuvant enhances the efficacy of DC based cancer vaccines in treating tumours. Methods In this study we have used tocotrienol-rich fraction (TRF, a non-toxic natural compound, as an adjuvant to enhance the effectiveness of DC vaccines in treating mouse mammary cancers. In the mouse model, six-week-old female BALB/c mice were injected subcutaneously with DC and supplemented with oral TRF daily (DC+TRF and DC pulsed with tumour lysate from 4T1 cells (DC+TL. Experimental mice were also injected with DC pulsed with tumour lysate and supplemented daily with oral TRF (DC+TL+TRF while two groups of animal which were supplemented daily with carrier oil (control and with TRF (TRF. After three times vaccination, mice were inoculated with 4T1 cells in the mammary breast pad to induce tumour. Results Our study showed that TRF in combination with DC pulsed with tumour lysate (DC+TL+TRF injected subcutaneously significantly inhibited the growth of 4T1 mammary tumour cells as compared to control group. Analysis of cytokines production from murine splenocytes showed significant increased productions of IFN-γ and IL-12 in experimental mice (DC+TL+TRF compared to control, mice injected with DC without TRF, mice injected with DC pulsed with tumour lysate and mice supplemented with TRF alone. Higher numbers of cytotoxic T cells (CD8 and natural killer cells (NK were observed in the peripheral blood of TRF adjuvanted DC pulsed tumour lysate mice. Conclusion Our study show that TRF has the potential to be an adjuvant to augment DC based immunotherapy.

    Ki67 labeling index (Ki67 LI) is a measure of tumor proliferation. In breast cancer, evidence supporting its prognostic value is clear and its predictive value for response to treatment finds some benefits. However studies of Ki67 LI as a predictive marker in early breast cancer are still limited worldwide and there is no data in Thailand. To assess the predictive value of Ki67 expression for adjuvant chemotherapy in patients with node-negative, hormone receptor-positive breast cancer The authors retrospectively evaluated 127 diagnosed early breast cancer with node-negative, hormone receptor-positive patients and receiving adjuvant systemic treatment at Siriraj hospital. Disease free survival (DFS) was compared with the log-rank test according to Ki67 LI and adjuvant systemic treatment (chemoendocrine therapy and endocrine therapy alone). At a median follow-up of 3.3 years. The 5-year DFS rate was 79% for patients with low Ki67 expression and 75% for patients with high Ki67 expression. Of the 127 patients, 56 (44.1%) received chemoendocrine therapy and 71 (55.9%) were treated with endocrine therapy alone. There was no different effect of DFS among those receiving adjuvant endocrine therapy alone and those receiving adjuvant chemoendocrine therapy depending on Ki67 expression. Among patients with node-negative, hormone receptor-positive breast cancer, a high Ki67 LI had worse DFS trend than a low Ki67 LI but the Ki67 LI did not predict the efficacy of adjuvant chemotherapy.

    The indications for and the efficacy of radiation therapy after radical operation for patients with prostate cancer are not clear. We analyzed the treatment results of adjuvant radiotherapy and salvage radiotherapy after radical prostatectomy. Between September 1997 and November 2004, 57 patients received adjuvant radiotherapy or salvage radiotherapy after radical prostatectomy. Fifteen patients received radiation therapy because of positive margins and/or extracapsular invasion in surgical specimens (adjuvant group). Forty-two patients received radiation therapy because of rising prostate-specific antigen (PSA) during follow-up (salvage group). Radiation therapy was delivered to the fossa of the prostate±seminal vesicles by a three-dimensional (3-D) conformal technique to a total dose of 60-66 Gy (median, 60 Gy). Biochemical control was defined as the maintenance of a PSA level of less than 0.2 ng/ml. The median follow-up period after radiation therapy was 33 months (range, 12-98 months). Three-year biochemical control rates were 87% for the adjuvant group and 61% for the salvage group. For patients in the salvage group treated without hormone therapy, the preradiation PSA value was the most significant factor for the biochemical control rate. The 3-year biochemical control rate was 93% in patients whose preradiation PSA was 0.5 ng/ml or less and 29% in patients whose preradiation PSA was more than 0.5 ng/ml. No severe adverse effects (equal to or more than grade 3) were seen in treated patients. Radiation therapy after radical prostatectomy seemed to be effective for adjuvant therapy and for salvage therapy in patients with a preradiation PSA of 0.5 ng/ml or less. Also, radiation to the fossa of the prostate±seminal vesicles, to a total dose of 60-66 Gy, using a three-dimensional (3-D) conformal technique, seemed to be safe. (author)

    Prior studies have indicated that patients with colorectal cancer with deficient mismatch repair have particular clinicopathologic features that distinguish them from patients with tumors with proficient mismatch repair. However, the effect of the mismatch repair status on outcomes after adjuvant chemotherapy for pancreatic cancer is still unknown. Pancreatic cancer patients who underwent R0 resection between January 2013 and December 2015 at Fudan University Shanghai Cancer Center were included in this study. Mismatch repair status was determined by immunohistochemistry of mismatch repair proteins. Prognostic factors for deficient mismatch repair and proficient mismatch repair tumors were analyzed using Cox models. In total, 442 of 590 patients met the inclusion criteria, and their mismatch repair status was determined; the study group consisted of 75 patients with deficient mismatch repair and 367 patients with proficient mismatch repair. Among the 147 patients who underwent surgery alone, patients with deficient mismatch repair tumors had a better overall survival than patients with proficient mismatch repair tumors (hazard ratio = 0.555 [95% confidence interval 0.331-0.931]; P = .026). Compared with patients who underwent surgery, 161 patients who received gemcitabine-based adjuvant chemotherapy had improvements in both disease-free survival and overall survival, regardless of mismatch repair status. However, 5-fluorouracil-based adjuvant chemotherapy yielded a favorable disease-free survival in the proficient mismatch repair group but conferred no survival advantage in the deficient mismatch repair group (hazard ratio = 0.930 [95% confidence interval 0.497-1.743]; P = .821). Mismatch repair status in pancreatic cancer patients is not only a prognostic indicator but also a potential guiding factor for the use of 5-fluorouracil-based adjuvant chemotherapy.

    Purpose: Prolonged radiation therapy treatment time (RTT) is associated with worse survival in several tumor types. This study investigated whether delays during adjuvant radiation therapy impact overall survival (OS) in gastric cancer. Methods and Materials: The National Cancer Data Base was queried for patients with resected gastric cancer who received adjuvant radiation therapy with National Comprehensive Cancer Network–recommended doses (45 or 50.4 Gy) between 1998 and 2006. RTT was classified as standard (45 Gy: 33-36 days, 50.4 Gy: 38-41 days) or prolonged (45 Gy: >36 days, 50.4 Gy: >41 days). Cox proportional hazards models evaluated the association between the following factors and OS: RTT, interval from surgery to radiation therapy initiation, interval from surgery to radiation therapy completion, radiation therapy dose, demographic/pathologic and operative factors, and other elements of adjuvant multimodality therapy. Results: Of 1591 patients, RTT was delayed in 732 (46%). Factors associated with prolonged RTT were non-private health insurance (OR 1.3, P=.005) and treatment at non-academic facilities (OR 1.2, P=.045). Median OS and 5-year actuarial survival were significantly worse in patients with prolonged RTT compared with standard RTT (36 vs 51 months, P=.001; 39 vs 47%, P=.005); OS worsened with each cumulative week of delay (P<.0004). On multivariable analysis, prolonged RTT was associated with inferior OS (hazard ratio 1.2, P=.002); the intervals from surgery to radiation therapy initiation or completion were not. Prolonged RTT was particularly detrimental in patients with node positivity, inadequate nodal staging (<15 nodes examined), and those undergoing a cycle of chemotherapy before chemoradiation therapy. Conclusions: Delays during adjuvant radiation therapy appear to negatively impact survival in gastric cancer. Efforts to minimize cumulative interruptions to <7 days should be considered

However, musculoskeletal pain is a common adverse effect encountered in patients receiving this treatment. We aimed to evaluate the risk factors for the development of antihormonal treatment-associated musculoskeletal pain (AHAMP and its impact on the health-related quality of life (HRQOL.Patients and methods: A cross-sectional survey of 78 consecutive breast cancer patients receiving adjuvant antihormonal treatment for early-stage breast cancer in an academic medical oncology clinic was conducted. AHAMP was assessed by Health Assessment Questionnaire (HAQ and 10 cm visual analog scale (VAS. HRQOL was assessed by self-administered short form 36 and Functional Assessment of Cancer Therapy-Breast subscale surveys.Results: AHAMP was found to be present in 37 (47.7% patients. In multivariate regression analysis, having a normal body mass index (<30 kg/m2, cigarette smoking, and low serum vitamin D level (20 ng/mL were found to be independent risk factors. In HRQOL assessment, physical and mental scores were found to be significantly lower in patients with joint arthralgia.Conclusion: AHAMP has an adverse effect on the quality of life of breast cancer patients receiving adjuvant antihormonal treatment, and assessment of predictive factors is important for identification of patient groups at risk of developing this condition.

    For patients with resectable gastric adenocarcinoma, perioperative chemotherapy and adjuvant chemoradiotherapy (CRT) are considered standard options. In the current study, the authors used the National Cancer Data Base to compare overall survival (OS) between these regimens. Patients who underwent gastrectomy for nonmetastatic gastric adenocarcinoma from 2004 through 2012 were divided into those treated with perioperative chemotherapy without RT versus those treated with adjuvant CRT. Survival was estimated and compared using univariate and multivariate models adjusted for patient and tumor characteristics, surgical margin status, and the number of lymph nodes examined. Subset analyses were performed for factors chosen a priori, and potential interactions between treatment and covariates were assessed. A total of 3656 eligible patients were identified, 52% of whom underwent perioperative chemotherapy and 48% of whom received postoperative CRT. The median follow-up was 47 months, and the median age of the patients was 62 years. Analysis of the entire cohort demonstrated improved OS with adjuvant RT on both univariate (median of 51 months vs 42 months; P = .013) and multivariate (hazard ratio, 0.874; 95% confidence interval, 0.790-0.967 [P = .009]) analyses. Propensity score-matched analysis also demonstrated improved OS with adjuvant RT (median of 49 months vs 39 months; P = .033). On subset analysis, a significant interaction was observed between the survival impact of adjuvant RT and surgical margins, with a greater benefit of RT noted among patients with surgical margin-positive disease (hazard ratio with RT: 0.650 vs 0.952; P for interaction Cancer Data Base analysis, the use of adjuvant RT in addition to chemotherapy was associated with a significant OS advantage for patients with resected gastric cancer. The survival advantage observed with adjuvant CRT was most pronounced among patients with positive surgical margins. Cancer 2017;123:3402-9. © 2017 American

    To evaluate the toxicity and efficacy of adjuvant chemotherapy after radiotherapy for patients with locally advanced head and neck squamous cancer, 40 patients, previously untreated (6 with stage III and 34 with stage IV; 26 with resectable, 10 with unresectable and 4 patients with inoperable) were treated with radiotherapy followed by adjuvant chemotherapy (Nedaplatin /tegafur-uracil (UFT)) at our outpatient clinic. The primary site was identified in the larynx or hypopharynx in 15, oral cavity or oropharynx in 11, sinuses in 6, nasopharynx in 4, unknown primary in 3, and parotis in 1 patient. Treatment consisted of 6 courses of Nedaplatin 80 mg/m{sup 2} repeated at 4 weeks intervals, and one-year oral administration of UFTE 400mg/day, after radiotherapy. Toxicities included leukopenia (grade 3, 20.5%, grade 4, 2.6%), thrombocytopenia (grade 3, 7.7%). There was one death due to gastric ulcer. Twenty-five patients (62.5%) received 6 courses of adjuvant chemotherapy. Two-year overall survival rate was 100% for stage III and 61.1% for stage IV. Over the same period, the progression-free survival rate was 83.3% for stage III and 46.1% for stage IV. 85.7% of complete response (CR) (12/14 patients) and 63.6% of partial response (PR) (14/22 patients) to radiotherapy showed that the effect of radiotherapy was maintained during adjuvant chemotherapy. If the effect of radiotherapy was maintained during adjuvant chemotherapy, the two-year progression free survival rate was not different between 81.8% for CR to radiotherapy and 81.3% for PR. The rate of distant failure was 2.5%, which was lower than that citedin previous reports. This adjuvant chemotherapy regimen is tolerable at outpatient clinics and might suppress distant metastasis after radiotherapy. (author)

    Background: We studied whether hormonal therapy, (neo)adjuvant to radiotherapy for localized prostate cancer, is related to an increase in depression and whether this is caused by the hormonal therapy itself or by the relatively poor prognosis of patients who get (neo)adjuvant hormonal therapy. Methods: Between 2002 and 2005, 288 patients, irradiated for prostate cancer (T1-3N0M0), were studied prospectively in two clinics. In one clinic almost all patients received (neo)adjuvant androgen deprivation (Bicalutamide + Gosereline). In a second clinic hormonal therapy was prescribed mainly for high risk patients. This allowed us to separate the effects of hormonal therapy and the patient's prognosis. Results: During the course of hormonal therapy, depression was significantly heightened by both hormone use (p < 0.001) and poor prognosis (p < 0.01). After completion of hormonal therapy, poor prognosis continued to affect the depression score (p < 0.01). The increase was, however, small. Conclusions: Depression was mildly increased in patients receiving hormonal therapy. The increase appeared to be related to both the hormone therapy itself and the high risk status of patients. High risk status, with the associated poor prognosis, had a more sustained effect on depression. The rise was statistically significant, but was too small, however, to bear clinical significance.

    A randomized, controlled trial of adjuvant immunochemotherapy with PSK (Kureha Chemical Industry Co., Tokyo, Japan) in curatively resected colorectal cancer was studied in 35 institutions in the Kanagawa prefecture. From March 1985 to February 1987, 462 patients were registered. Four hundred forty-eight of those patients (97.0 percent) satisfied the eligibility criteria. The control group received mitomycin C intravenously on the day of and the day after surgery, followed by oral 5-fluorouracil (5-FU) administration for over six months. The PSK group received PSK orally for over three years, in addition to mitomycin C and 5-FU as in the control group. At the end of February 1990, the median follow-up time for this study was four years (range, three to five years). The disease-free survival curve and the survival curve of the PSK group were better than those of the control group, and differences between the two groups were statistically significant (disease-free survival, P = 0.013; survival, P = 0.013). These results indicate that adjuvant immunochemotherapy with PSK was beneficial for curatively resected colorectal cancer.

    Purpose: To determine whether adjuvant chemoradiotherapy (CRT) improves the outcome of cervical cancer patients with intermediate risk factors. Methods and Materials: Between January 2000 and June 2006, the medical records of 735 patients who had undergone radical surgery for Stage IB-IIA cervical cancer were reviewed retrospectively. Of the 735 patients, 172 with two or more intermediate risk factors (i.e., lymphovascular space involvement, deep stromal invasion, and tumor size ≥2 cm) were grouped as follows according to the adjuvant treatment received: 34 patients, no further treatment; 49 patients, RT; and 89 patients, CRT. The significance of the clinical parameters and recurrence-free survival of each group were analyzed. Results: Of the 172 patients with any of the intermediate risk factors, 137 (79.6%) had two or more intermediate risk factors. Of the 172 patients, 12 developed recurrences (6.4%)->(7.0%), with 6 in the pelvis and 6 in distant sites. All 12 recurrences occurred in those who had two or more intermediate risk factors (sensitivity, 100%); however, only six recurrences were detected in patients who met the Gynecologic Oncology Group criteria for the intermediate-risk group (sensitivity, 50%; Z test, p .05). Conclusion: Postoperative adjuvant CRT can improve the outcome of cervical cancer patients with intermediate risk factors, with low increase in toxicity.

    Full Text Available Synthetic lipopeptides have been widely used as vaccine adjuvants to enhance immune responses. The present study demonstrated that the tryptic N-terminal fragment of the lipoprotein rlipo-D1E3 (lipo-Nter induces superior antitumor effects compared to a synthetic lipopeptide. The lipo-Nter was purified and formulated with protein or peptide vaccines to determine if lipo-Nter could be used as a novel adjuvant and could induce antitumor immunity in a cervical cancer model. Purified lipo-Nter activated the maturation of bone marrow-derived dendritic cells (BM-DCs, leading to the secretion of TNF-α through TLR2/6 but not TLR1/2. A recombinant mutant HPV16 E7 (rE7m protein was mixed with lipo-Nter to immunize the mice; the anti-E7 antibody titers were increased, and the T helper cells were skewed toward the Th1 fate (increased IL-2 and decreased IL-5 secretion. Single-dose injection of rE7m and lipo-Nter inhibited tumor growth, but the injection of rE7m alone did not. Accordingly, lipo-Nter also enhanced the antitumor immunity of the E7-derived peptide but not the synthetic lipopeptide (Pam3CSK4. We demonstrated that the lipo-Nter of a bacterial-derived recombinant lipoprotein is a novel adjuvant that could be used for the development of a new generation of vaccines.

    Adjuvant chemotherapy regime for ovarian cancer patients remains to be a contentious issue. The aim of this study was to compare the overall and progression-free survival of women with ovarian cancer before and after introduction of paclitaxel in our unit in 1992. A sample of 112 women who received adjuvant therapy following surgery for ovarian cancer was collected, 68 (61%) received platinum+alkylating agent before 1992 and later 44 (39%) received platinum+paclitaxel. Five-year survival was same in both treatment groups when there was no macroscopic disease after surgery (78% versus 70%) and when residual disease was <2 cm (50% versus 40%). Survival was greater in women with residual disease >2 cm in the platinum+paclitaxel group (50% versus 24%), (p = 0.04). However, progression-free survival was similar in both groups irrespective of stage or residual volume of disease. Therefore consideration to selective use of paclitaxel could reduce patient morbidity and costs significantly.

    1997-01-01

    PURPOSE: the long-term outcomes of patients undergoing local excision with or without pelvic irradiation were examined to define the role of adjuvant irradiation following local excision of T1 and T2 rectal cancers. METHODS: From January 1966 to January 1997, 114 patients underwent local excision for rectal cancer. Fifty-nine patients underwent local excision alone, and 55 patients received adjuvant pelvic irradiation (45 Gy to 65.8 Gy)+/-concurrent 5-fluorouracil chemotherapy. Outcome was assessed by treatment, stage, and pathologic features of tumor grade and lymphatic/venous vessel involvement. RESULTS: Of the 114 patients treated by local excision, 90 had T1/T2 tumors. The 5-year actuarial local control (LC) and recurrence-free survival (RFS) of these 90 patients are shown (with numbers of patients at risk at 5 years) in the table below. The 5-year actuarial local control and recurrence-free survival (RFS) for T1/T2 patients treated by local excision alone was 85% and 77%, respectively. The corresponding values for patients undergoing local excision and adjuvant irradiation alone were 88% and 78%, respectively. All 20 patients treated by adjuvant chemoradiation achieved 5-year actuarial local control and had a recurrence-free survival of 88%. The improved outcomes in the adjuvant radiation group become more impressive when the higher T stage distribution of this group is considered. Fifty-five percent of the group receiving adjuvant radiation were stage T2 compared to only 14% of patients treated by local excision alone. Subgroup analysis was performed on those features recognized as poor prognostic factors including poorly differentiated histology and lymphatic vascular invasion. Patients in the local excision alone group with one or more adverse pathologic features had reduced rates of local control compared to those with the absence of such features (38% vs. 91%, respectively, p=0.02). In comparison, the 5 patients with poor prognostic features treated by

    Objective This study aims to examine factors associated with the use of adjuvant chemotherapy and the use of oxaliplatin after curative resection in stage III colon cancer patients and assesses the effect of their use in three-year survival. Methods This retrospective cohort study was conducted using Puerto Rico Central Cancer Registry-Health Insurance Linkage Database. The study cohort consisted of stage III colon cancer patients with a curative surgery in the period 2008–2012. Multivariate logistic regression was used to estimate adjusted odds ratios. Kaplan-Meier methods and Cox proportional hazards models were used to assess the association between adjuvant chemotherapy and oxaliplatin use and overall survival and risk of death, respectively. Results Overall, 75% of the study population received adjuvant chemotherapy during the study period. Factors statistically associated with receiving adjuvant chemotherapy within four months after resection included being married (adjusted odds ratio [AOR] 1.64; 95% CI 1.18–2.28; p = 0.003), and being enrolled in Medicare (AOR 1.68; 95% CI: 1.03–2.75; p = 0.039) or Medicaid and Medicare dual eligible (AOR 1.66; 95% CI: 1.06–2.60; p = 0.028). However, patients aged ≥70 years were less likely to receive adjuvant chemotherapy (AOR 0.22; 95%CI 0.14–0.36; p<0.001). Discussion We observed a significant reduction in mortality in adjuvant chemotherapy treated patients. Similarly, patients <70 years treated with oxaliplatin had significantly lower risk of death than those who did not, although for patients ≥70 years no statistical significance was achieved. Future studies should assess effective interventions to reduce barriers to access guideline-based recommended colon cancer treatment. PMID:29584752

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic

In this study, we examined the long-term oncologic outcomes in breast cancer patients who underwent curative surgery according to their pre-existing comorbid conditions and analyzed the association between the co-morbidity and the use of adjuvant therapies.The medical records of 2,501 patients who underwent surgery for primary breast cancer from June 2006 to June 2010 were reviewed retrospectively. The patients were classified into three groups according to preoperative ASA status determined by the anesthesiologists. Clinico-pathologic characteristics and survival outcomes of the patients were compared among the different co-morbidity groups.There were 1,792 (71.6%, 665 (26.6%, and 44 (1.8% patients in ASA I, II, and III, respectively. Total 95 (3.8% deaths and 269 (10.8% recurrences (loco-regional and distant occurred during the median follow-up period of 71 months. Patients with high comorbidity showed significantly higher rate of deaths (51 (2.8%, 38 (5.7% and 6 (13.6% deaths in ASA I, II and III group, respectively, p<0.001. The ASA 3 patients also showed significantly higher rate of breast cancer recurrence when compared to other groups (180 (10.0%, 80 (12.0% and 9 (20.5% in ASA I, II, and III, respectively, p = 0.041. Significantly fewer patients in the high co-morbidity group received adjuvant therapies (77 (4.3%, 44 (6.6% and 8 (18.2% in ASA I, II, and III, respectively, p<0.001. The increased recurrence of breast cancer in the high morbidity group was mostly seen in patients who did not receive adjuvant therapies. The incidence of serious adverse effect during the adjuvant therapy did not differ according to the co-morbidity conditions.In this study, high comorbidity was related to increased risk of death and recurrence in breast cancer. The increased risk of recurrence in high co-morbidity group was mostly seen in

    Purpose: To evaluate the association between the interval from breast-conserving surgery (BCS) to radiotherapy (RT) and the clinical outcome among patients treated with adjuvant endocrine therapy. Patients and Methods: Patient information was obtained from three International Breast Cancer Study Group trials. The analysis was restricted to 964 patients treated with BCS and adjuvant endocrine therapy. The patients were divided into two groups according to the median number of days between BCS and RT and into four groups according to the quartile of time between BCS and RT. The endpoints were the interval to local recurrence, disease-free survival, and overall survival. Proportional hazards regression analysis was used to perform comparisons after adjustment for baseline factors. Results: The median interval between BCS and RT was 77 days. RT timing was significantly associated with age, menopausal status, and estrogen receptor status. After adjustment for these factors, no significant effect of a RT delay ≤20 weeks was found. The adjusted hazard ratio for RT within 77 days vs. after 77 days was 0.94 (95% confidence interval [CI], 0.47-1.87) for the interval to local recurrence, 1.05 (95% CI, 0.82-1.34) for disease-free survival, and 1.07 (95% CI, 0.77-1.49) for overall survival. For the interval to local recurrence the adjusted hazard ratio for ≤48, 49-77, and 78-112 days was 0.90 (95% CI, 0.34-2.37), 0.86 (95% CI, 0.33-2.25), and 0.89 (95% CI, 0.33-2.41), respectively, relative to ≥113 days. Conclusion: A RT delay of ≤20 weeks was significantly associated with baseline factors such as age, menopausal status, and estrogen-receptor status. After adjustment for these factors, the timing of RT was not significantly associated with the interval to local recurrence, disease-free survival, or overall survival.

    BACKGROUND: Although many trials have been conducted to evaluate the feasibility and effectiveness of adjuvant chemotherapy (ACT) for patients with stomach cancer, the benefits of ACT remain unclear. Moreover, some authors have reported that ACT increased the incidence of second malignancy. The risk of second malignancy was evaluated in patients who underwent treatment for stomach cancer in the past 20 years at Osaka Medical Center for Cancer and Cardiovascular Diseases.METHODS: The study population consisted of 1925 patients who underwent gastrectomies for stomach cancer between the years 1978 and 1992 and who received follow-up examinations to check for second malignancies. They included 1114 patients who underwent surgery only (group A) and 811 who underwent surgery and received chemotherapy (group B). The observed incidence of second malignancy (O) was compared with the expected incidence (E), calculated by the person-year method, using data from the Cancer Registry in Osaka.RESULTS: The average follow-up period was 7.99 years. The total number of patients with a second malignancy was 127 (men, 97; women, 30); 72 patients had the second malignancy in digestive organs; 27 in respiratory organs; and 28 in other organs. The relative risks of a second malignancy in group A and B patients were 1.05 and 1.02 (differences between the two groups were not significant). The relative risks of a second malignancy in patients who received ACT with 5-fluorouracil, Tegafur and Uracil, and FT207 were 0.79, 1.01, and 1.06, respectively (differences between the groups were not significant).CONCLUSION: The risk of second malignancy after chemotherapy for stomach cancer was not high in comparison with the expected incidence. Adjuvant chemotherapy did not increase the risk of a second malignancy.

  11. Adjuvant treatment of breast cancer patients with trastuzumab

    2007-01-01

    Trastuzumab is a monoclone antibody directed against HER2 receptors that are overexpressed in approximately 20% of breast cancer patients. The present paper presents five clinical trials in which trastuzumab was applied in breast cancer patients in adjuvant setting. The results of all the trials consistently demonstrate a high efficacy of this target drug in the patients with HER2 positive tumours. So far, no formal guidelines for using trastuzumab in adjuvant setting for breast cancer have been approved. The reasons are many: (i) mean observation time in the studies done so far was considerably short; (ii) the drug was used according to different schedules, (iii) the overall time of treatment with trastuzumab was different in each trial, (iv) late side effects of treatment with trastuzumab are inadequately investigated, and (v) nobody can so far say for sure for which HER2 status patients therapy with trastuzumab is really beneficial. Trastuzumab is definitely very helpful in the treatment of the HER2-positive breast cancer patients that are hormone-independent and of anatomically larger tumours; but, what the absolute benefit of trastuzumab therapy in the treatment of small hormone-dependent tumours is remains a mystery. Incidentally, it must be borne in mind that cardiotoxicity, the well known side effect, may put particularly elderly patients at risk of death, thus beating any treatment advantages down. It has also not been yet resolved at what time it would be most appropriate to start with the therapy with trastuzumab, what would be the optimal duration of the therapy and whether trastuzumab is to be administered concurrently with chemotherapy or immediately after it? What is the optimal treatment duration, one or two years or only a few months? In addition there is still a question of optimal HER2 status determination and which HER2 status predicts for trastuzumab benefit. These questions will hopefully be answered after a longer observation time of the

    Studies indicate that the incidence of young women diagnosed with colorectal cancer is rising, thus there is an increasing number of female colorectal cancer survivors of premenopausal and child-bearing age. Adjuvant FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) chemotherapy is the most widely used standard treatment for stage III and high-risk stage II colon cancer. We evaluated the incidence of FOLFOX-induced amenorrhea in women age 50 and younger treated with adjuvant therapy for colorectal cancer. A search of pharmacy records identified 119 women age 50 or younger who received adjuvant FOLFOX chemotherapy at Memorial Sloan-Kettering for stage II or III colorectal cancer from January 2002 and January 2011. Eligible patients were mailed an anonymous questionnaire. The returned surveys were reviewed and the results tallied. Seventy-three patients returned the questionnaire. Twenty-four patients were excluded from analysis: 19 were treated with pelvic radiotherapy, 2 patients had undergone bilateral oophorectomy, 2 had a hysterectomy, and 1 stopped menstruating before diagnosis. Forty-nine patient responses were analyzed. In total, 41% (n = 20) experienced amenorrhea during chemotherapy. Sixteen percent had persistent amenorrhea 1 year after completion of chemotherapy. The incidence of amenorrhea during chemotherapy trended higher in patients aged older than 40 compared with patients aged 40 and younger (59% vs. 31% [P = .075]). There was no statistically significant difference in persistent amenorrhea between the 2 age groups (24% vs. 13%; P = .42). In this retrospective series, there appears to be a trend toward FOLFOX induced amenorrhea during chemotherapy increasing with age. Twenty-four percent of women older than the age of 40 were found to have persistent amenorrhea after FOLFOX therapy. Because of the small sample size, the study is underpowered to detect a statistically significant difference between older and younger patients. Prospective studies

    External beam radiation therapy (EBRT) with concomitant chemotherapy (cCT) (=RCT) plus intracavitary (±interstitial) brachytherapy (iBT) is standard of care for advanced cervical cancer. The aim of this study was to evaluate morbidity and survival outcome of simple adjuvant hysterectomy (AH) after EBRT/cCT and to compare it with the standard treatment. Patients with FIGO stage III cervical cancer were treated with EBRT/cCT and then divided in two groups: group 1 was further treated with standard intracavitary/interstitial BT, while group 2 underwent AH. From 881 women with cervical cancer, 248 were eligible for analysis: 161 received iBT and 87 underwent AH. The median follow-up of the study was 53 months. Clinical and pathological characteristics were well balanced in the two groups. After EBRT/cCT, complete clinical response was observed in 121 (48.8%) of 246 patients. Clinical complete response was observed in 81 (50.3%) of 161 patients in group 1. At 6 weeks after EBRT/cCT, 40 (46.0%) of 87 patients in the surgery group had pathological complete response. Intra- and postoperative complications were observed in 10 (11.5%) of 87 cases. The rates of locoregional recurrence and metastasis were similar in both groups. Progression-free (PFS) and disease-specific overall survival (DOS) for these patients were similar between the control and surgery group. Interestingly, PFS and DOS were significantly improved by AH for the patients with residual tumor. AH could improve survival in patients with residual disease after RCT and is characterized by a low complication rate. (orig.)

    Full Text Available BACKGROUND: Adjuvant! Online is a web-based application designed to provide 10 years survival probability of patients with breast cancer. Several predictors have not been assessed in the original Adjuvant! Online study. We provide the validation of Adjuvant! Online algorithm on two breast cancer datasets, and we determined whether the accuracy of Adjuvant! Online is improved with other well-known prognostic factors. PATIENTS AND METHODS: The French data set is composed of 456 women with early breast cancer. The Dutch data set is composed of 295 women less than 52 years of age. Agreement between observation and Adjuvant! Online prediction was checked, and logistic models were performed to estimate the prognostic information added by risk factors to Adjuvant! Online prediction. RESULTS: Adjuvant! Online prediction was overall well-calibrated in the French data set but failed in some subgroups of such high grade and HER2 positive patients. HER2 status, Mitotic Index and Ki67 added significant information to Adjuvant! Online prediction. In the Dutch data set, the overall 10-year survival was overestimated by Adjuvant! Online, particularly in patients less than 40 years old. CONCLUSION: Adjuvant! Online needs to be updated to adjust overoptimistic results in young and high grade patients, and should consider new predictors such as Ki67, HER2 and Mitotic Index.

    Full Text Available Tocotrienol-rich fraction (TRF from palm oil is reported to possess anti-cancer and immune-enhancing effects. In this study, TRF supplementation was used as an adjuvant to enhance the anti-cancer effects of dendritic cells (DC-based cancer vaccine in a syngeneic mouse model of breast cancer. Female BALB/c mice were inoculated with 4T1 cells in mammary pad to induce tumor. When the tumor was palpable, the mice in the experimental groups were injected subcutaneously with DC-pulsed with tumor lysate (TL from 4T1 cells (DC+TL once a week for three weeks and fed daily with 1 mg TRF or vehicle. Control mice received unpulsed DC and were fed with vehicle. The combined therapy of using DC+TL injections and TRF supplementation (DC+TL+TRF inhibited (p<0.05 tumor growth and metastasis. Splenocytes from the DC+TL+TRF group cultured with mitomycin-C (MMC-treated 4T1 cells produced higher (p<0.05 levels of IFN-γ and IL-12. The cytotoxic T-lymphocyte (CTL assay also showed enhanced tumor-specific killing (p<0.05 by CD8(+ T-lymphocytes isolated from mice in the DC+TL+TRF group. This study shows that TRF has the potential to be used as an adjuvant to enhance effectiveness of DC-based vaccines.

    Adjuvant chemotherapy for stage II colon cancer is a controversial practice and is not recommended by the French Consensus Conference outside of therapeutic trial. To assess, within a well-defined population, the influence of hospital characteristics in this practice. In the Rhône-Alpes region (10% of the French population), 534 patients presenting with colon cancer stage II were operated on in 81 hospitals in the year 2000. The influence of hospital characteristics on the use of adjuvant chemotherapy was assessed using a multivariate logistic regression. Overall, 19.5% of patients received adjuvant chemotherapy. Younger age, T4 tumour, hospital volume lower than 20 colon cancer surgeries [odds ratio (OR) 2.96; Pclinical complications at diagnosis were independently associated with higher rates of chemotherapy. On the other hand, a number of examined lymph nodes lower than recommendations did not have any influence on chemotherapy use. Hospital characteristics had independently influenced the practice of adjuvant chemotherapy in stage II colon cancer. The more important institutional factor was the hospital procedure volume. The decisions of the multidisciplinary committees appeared at times paradoxical; a more comprehensive evaluation of this practice is needed.

    Adjuvant therapy with an aromatase inhibitor improves outcomes, as compared with tamoxifen, in postmenopausal women with hormone-receptor-positive breast cancer. In two phase 3 trials, we randomly assigned premenopausal women with hormone-receptor-positive early breast cancer to the aromatase inhibitor exemestane plus ovarian suppression or tamoxifen plus ovarian suppression for a period of 5 years. Suppression of ovarian estrogen production was achieved with the use of the gonadotropin-releasing-hormone agonist triptorelin, oophorectomy, or ovarian irradiation. The primary analysis combined data from 4690 patients in the two trials. After a median follow-up of 68 months, disease-free survival at 5 years was 91.1% in the exemestane-ovarian suppression group and 87.3% in the tamoxifen-ovarian suppression group (hazard ratio for disease recurrence, second invasive cancer, or death, 0.72; 95% confidence interval [CI], 0.60 to 0.85; P<0.001). The rate of freedom from breast cancer at 5 years was 92.8% in the exemestane-ovarian suppression group, as compared with 88.8% in the tamoxifen-ovarian suppression group (hazard ratio for recurrence, 0.66; 95% CI, 0.55 to 0.80; P<0.001). With 194 deaths (4.1% of the patients), overall survival did not differ significantly between the two groups (hazard ratio for death in the exemestane-ovarian suppression group, 1.14; 95% CI, 0.86 to 1.51; P=0.37). Selected adverse events of grade 3 or 4 were reported for 30.6% of the patients in the exemestane-ovarian suppression group and 29.4% of those in the tamoxifen-ovarian suppression group, with profiles similar to those for postmenopausal women. In premenopausal women with hormone-receptor-positive early breast cancer, adjuvant treatment with exemestane plus ovarian suppression, as compared with tamoxifen plus ovarian suppression, significantly reduced recurrence.

    Bisphosphonates have been studied in randomised trials in early breast cancer to investigate their ability to prevent cancer treatment-induced bone loss (CTIBL) and reduce the risk of disease recurrence and metastasis. Treatment benefits have been reported but bisphosphonates do not currently have regulatory approval for either of these potential indications. This consensus paper provides a review of the evidence and offers guidance to breast cancer clinicians on the use of bisphosphonates in early breast cancer. Using the nominal group methodology for consensus, a systematic review of the literature was augmented by a workshop held in October 2014 for breast cancer and bone specialists to present and debate the available pre-clinical and clinical evidence for the use of adjuvant bisphosphonates. This was followed by a questionnaire to all members of the writing committee to identify areas of consensus. The panel recommended that bisphosphonates should be considered as part of routine clinical practice for the prevention of CTIBL in all patients with a T score of 18,000 patients supports clinically significant benefits of bisphosphonates on the development of bone metastases and breast cancer mortality in post-menopausal women or those receiving ovarian suppression therapy. Therefore, the panel recommends that bisphosphonates (either intravenous zoledronic acid or oral clodronate) are considered as part of the adjuvant breast cancer treatment in this population and the potential benefits and risks discussed with relevant patients. © The Author 2015.

    Purpose: Large randomized trials have demonstrated significant survival benefits with the use of adjuvant chemotherapy or chemoradiation therapy for gastric cancer. The importance of adjuvant radiation therapy (RT) remains unclear. We performed an up-to-date meta-analysis of randomized trials testing the use of RT for resectable gastric cancer. Methods and Materials: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials testing adjuvant (including neoadjuvant) RT for resectable gastric cancer. Hazard ratios describing the impact of adjuvant RT on overall survival (OS) and disease-free survival (DFS) were extracted directly from the original studies or calculated from survival curves. Pooled estimates were obtained using the inverse variance method. Subgroup analyses were performed to determine whether the efficacy of RT varies with chemotherapy use, RT timing, geographic region, type of nodal dissection performed, or lymph node status. Results: Thirteen studies met all inclusion criteria and were used for this analysis. Adjuvant RT was associated with a significant improvement in both OS (HR = 0.78, 95% CI: 0.70-0.86, P<.001) and DFS (HR = 0.71, 95% CI: 0.63-0.80, P<.001). In the 5 studies that tested adjuvant chemoradiation therapy against adjuvant chemotherapy, similar effects were seen for OS (HR = 0.83, 95% CI: 0.67-1.03, P=.087) and DFS (HR = 0.77, 95% CI: 0.91-0.65, P=.002). Available data did not reveal any subgroup of patients that does not benefit from adjuvant RT. Conclusion: In randomized trials for resectable gastric cancer, adjuvant RT provides an approximately 20% improvement in both DFS and OS. Available data do not reveal a subgroup of patients that does not benefit from adjuvant RT. Further study is required to optimize the implementation of adjuvant RT for gastric cancer with regard to patient selection and integration with systemic therapy

    2014-01-01

    Full Text Available Background: Intraperitoneal administration of paclitaxel (PTX can elicit a marked clinical response in peritoneal metastases of gastric cancer. Methods: In this study, we retrospectively analyzed the clinical outcome of 17 patients who underwent R0 resection with D2 dissection for advanced gastric cancer with macroscopic serosal exposure and received intraperitoneal PTX as adjuvant therapy. Results: A pathological study revealed that the depth of invasion of the primary tumor was pT4a or pT4b in 10 cases, and that the pN stage was more than pN2 in 8 cases. Genetic analysis of peritoneal lavage fluid was performed in 14 cases, all of which were positive for carcinoembryonic antigen mRNA. In these patients, PTX was intraperitoneally administered at 20-60 mg/m2 with oral S-1 for 3-36 months after surgery. In a median follow-up period of 66 months, recurrence occurred in the liver and peritoneum in 2 (11.7% and 1 (5.9% patients, respectively, and no nodal recurrence was observed. Five-year overall survival and disease-free survival were 88.2 and 82.3%, respectively. Conclusion: Since these patients are considered to be a high-risk group for peritoneal recurrence, this result strongly suggests that adjuvant chemotherapy including intraperitoneal PTX is a promising protocol to improve the outcome of patients with advanced gastric cancer with serosal exposure.

    Conventional anthracyclines play an essential role for the treatment of breast cancer and have potent cytotoxic activity, but are associated with severe toxicity. In metastatic breast cancer, pegylated liposomal doxorubicin (PLD) is a formulation with efficacy similar to conventional doxorubicin but with reduced toxicity. This multicenter study evaluated the efficacy and safety of PLD-based adjuvant chemotherapy for women with stage I-III operable breast cancer. One hundred and eighty women with stage I-III breast cancer who received PLD-based adjuvant chemotherapy at six different Institutions in Taiwan from February 2002 to March 2008 were included and followed-up until April 2015. Treatment efficacy was determined by disease-free survival (DFS) rate and safety was evaluated by adverse events. The 5- and 10-year DFS rates were 76.3 and 72.6%, respectively. Univariate analysis revealed that tumor size >5 cm (p=0.045; hazard ratio=3.31) and stage III (hazard ratio=3.54; p=0.019) were each associated with shorter DFS. Only stage III (hazard ratio=5.60; p=0.018) retained statistical significance with regard to DFS in the multivariate analysis. Grade 3/4 hematological toxicity was neutropenia (n=13; 7.2%). The women receiving PLD had low-grade 3 or 4 nausea/vomiting, mucositis, and alopecia. Grade 3 hand-foot syndrome occurred in three patients (1.7%). PLD could be considered an effective and safe alternative to conventional anthracyclines in the treatment of stage I-III operable breast cancer.

    Purpose: To compare concomitant and sequential adjuvant chemoradiotherapy regimens in node-positive, operable breast cancer patients. Methods and Materials: This was a randomized, French, multicenter, phase III trial enrolling 638 eligible women with prior breast surgery and positive axillary dissection. Patients in Arm A received 500 mg/m 2 5-fluorouracil, 12 mg/m 2 mitoxantrone, and 500 mg/m 2 cyclophosphamide, with concomitant radiotherapy (50 Gy ± 10-20-Gy boost). Patients in Arm B received 500 mg/m 2 5-fluorouracil, 60 mg/m 2 epirubicin, and 500 mg/m 2 cyclophosphamide, with subsequent radiotherapy. Chemotherapy was administered on Day 1 every 21 days for 4 cycles. Results: Median treatment durations were 64 and 126 days (Arms A and B, respectively), with no significant difference in overall or disease-free survival. Five-year locoregional relapse-free survival favored patients with conservative surgery (two thirds of the population), with less local and/or regional recurrence in Arm A than in Arm B (3% vs. 9%; p 0.01). Multivariate analysis in this subgroup showed a 2.8-fold increased risk of locoregional recurrence with sequential chemoradiotherapy, independent of other prognostic factors (p = 0.027). Febrile neutropenia and Grade 3-4 leukopenia were significantly more frequent in Arm A. Subclinical left ventricular ejection fraction events at 1 year were more frequent with concomitant radiotherapy (p = 0.02). Conclusions: Concomitant radiotherapy with adjuvant fluorouracil, mitoxantrone, and cyclophosphamide has significantly better locoregional control in node-positive breast cancer after conservative surgery and 50% shorter treatment, albeit with slightly more acute toxicity. With mitoxantrone no longer available for adjuvant breast cancer treatment, alternative concomitant chemoradiotherapy studies are needed

    Serum carcinoembryonic antigen (CEA) is used to detect relapses from colon cancer following initial surgical or adjuvant treatment. There are little data on transient elevations of CEA while receiving chemotherapy in the adjuvant setting. We aimed to review patterns of change in CEA levels while receiving adjuvant chemotherapy and investigate associations between transient rises and patient survival. A retrospective review of patients in Auckland with a new diagnosis of colon cancer in 2001 or 2005 was performed and CEA values were collected. Three patient groups were defined: no increase in CEA; transient elevation in CEA; and persistent elevation in CEA. Kaplan-Meier methods were used to estimate 5-year survival; Cox regression and log-rank P-values were used to compare survival. Sixty-one patients with stage II or III disease who had received adjuvant chemotherapy had sufficient CEA data to be included in the analysis. Patients were followed up for a minimum of 7.4 years (or death). The 5-year overall survival was higher in the transient elevation in CEA group 95.0% and the no increase in CEA group 85.2% compared with the persistent elevation in CEA group 42.9%. There was no statistically significant difference in overall survival between the transient elevation group and the no increase group (P = 0.2). The group with a transient elevation in CEA during adjuvant chemotherapy did not have a poorer prognosis compared with the group that had no increase in CEA. This will be further examined in a population-based New Zealand-wide study of colorectal cancer diagnosis, treatment and outcome. © 2015 Wiley Publishing Asia Pty Ltd.

    The discrepancy between the surgical technique and the type of adjuvant chemotherapy used in clinical trials and patient outcomes in terms of overall survival rates has led to the generation of different adjuvant treatment protocols in distinct parts of the world. The adjuvant treatment recommendation is generally chemoradiotherapy in the United States, perioperative chemotherapy in the United Kingdom and parts of Europe, and chemotherapy in Asia. These options mainly rely on the United States Intergroup-0116, United Kingdom British Medical Research Council Adjuvant Gastric Infusional Chemotherapy, and the Asian Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer and Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer trials. However, the benefits were evident for only certain patients, which were not very homogeneous regarding the type of surgery, chemotherapy regimens, and stage of disease. Whether the dissimilarities in survival are attributable to surgical technique or intrinsic biological differences is a subject of debate. Regardless of the extent of surgery, multimodal therapy may offer modest survival advantage at least for diseases with lymph node involvement. Moreover, in the era of individualized treatment for most of the other cancer types, identification of special subgroups comprising those who will derive more or no benefit from adjuvant therapy merits further investigation. The aim of this review is to reveal the historical evolution and future reflections of adjuvant treatment modalities for resected gastric cancer patients. PMID:27190583

    Purpose To make recommendations regarding the use of bisphosphonates and other bone-modifying agents as adjuvant therapy for patients with breast cancer. Methods Cancer Care Ontario and ASCO convened a Working Group and Expert Panel to develop evidence-based recommendations informed by a systematic review of the literature. Results Adjuvant bisphosphonates were found to reduce bone recurrence and improve survival in postmenopausal patients with nonmetastatic breast cancer. In this guideline, postmenopausal includes patients with natural menopause or that induced by ovarian suppression or ablation. Absolute benefit is greater in patients who are at higher risk of recurrence, and almost all trials were conducted in patients who also received systemic therapy. Most studies evaluated zoledronic acid or clodronate, and data are extremely limited for other bisphosphonates. While denosumab was found to reduce fractures, long-term survival data are still required. Recommendations It is recommended that, if available, zoledronic acid (4 mg intravenously every 6 months) or clodronate (1,600 mg/d orally) be considered as adjuvant therapy for postmenopausal patients with breast cancer who are deemed candidates for adjuvant systemic therapy. Further research comparing different bone-modifying agents, doses, dosing intervals, and durations is required. Risk factors for osteonecrosis of the jaw and renal impairment should be assessed, and any pending dental or oral health problems should be dealt with prior to starting treatment. Data for adjuvant denosumab look promising but are currently insufficient to make any recommendation. Use of these agents to reduce fragility fractures in patients with low bone mineral density is beyond the scope of the guideline. Recommendations are not meant to restrict such use of bone-modifying agents in these situations.

    Despite the efficacy of postoperative adjuvant cisplatin (CDDP)-based chemotherapy for patients who have undergone surgical resection of non-small cell lung cancer (NSCLC), few reports have presented survival data for Asian patients treated with adjuvant chemotherapy involving a combination of CDDP and vinorelbine (VNR). This study was performed to evaluate the survival of patients with NSCLC who received postoperative adjuvant chemotherapy comprising CDDP + VNR. We retrospectively evaluated patients with NSCLC who received adjuvant chemotherapy comprising CDDP + VNR at the Shizuoka Cancer Center between February 2006 and October 2011. One hundred patients who underwent surgical resection of NSCLC were included in this study. The patients' characteristics were as follows: median age 63 years (range 36-74 years), female 34%, never-smokers 20%, and non-squamous NSCLC 73%. Pathological stages IIA, IIB, and IIIA were observed in 31, 22, and 47% of patients, respectively. The 5- and 2-year overall survival rates were 73 and 93%, respectively. The 5- and 2-year relapse-free survival rates were 53 and 62%, respectively. Univariate analysis of prognostic factors showed that patient characteristics (sex, histology, and pathological stage) and CDDP dose intensity were not significantly associated with survival. In 48 patients who developed NSCLC recurrence, the 5-year survival rate after recurrence was 29%, and the median survival time after recurrence was 37 months. Our results suggest that the prognosis after surgical resection of NSCLC and adjuvant chemotherapy comprising CDDP + VNR might be improving compared with previous survival data of adjuvant chemotherapy for NSCLC.

    Adjuvant chemotherapy for resected rectal cancer is widely used. However, studies on adjuvant treatment following neoadjuvant chemoradiotherapy (CRT) and total mesorectal excision (TME) have yielded conflicting results. Recent studies have focused on adding oxaliplatin to both preoperative and postoperative therapy, making it difficult to assess the impact of adjuvant oxaliplatin alone. This study was aimed at determining the impact of (i) any adjuvant treatment and (ii) oxaliplatin-containing adjuvant treatment on disease-free survival in CRT-pretreated, R0-resected rectal cancer patients. Patients undergoing R0 TME following 5-fluorouracil (5FU)-only-based CRT between January 1, 2008, and December 31, 2010, were selected from a nationwide registry. After propensity score matching (PSM), comparison of disease-free survival (DFS) using Kaplan-Meier analysis and log-rank test was performed in (i) patients receiving no vs. any adjuvant treatment and (ii) patients treated with adjuvant 5FU/capecitabine without vs. with oxaliplatin. Out of 1497 patients, 520 matched pairs were generated for analysis of no vs. any adjuvant treatment. Mean DFS was significantly prolonged with adjuvant treatment (81.8 ± 2.06 vs. 70.1 ± 3.02 months, p rectal cancer patients treated with neoadjuvant CRT and TME surgery under routine conditions, adjuvant chemotherapy significantly improved DFS. No benefit was observed for the addition of oxaliplatin to adjuvant chemotherapy in this setting.

    Women with a diagnosis of breast cancer may experience short- and long-term disease and treatment-related adverse physiological and psychosocial outcomes. These outcomes can negatively impact prognosis, health-related quality of life (HRQoL), and psychosocial and physical function. Physical activity may help to improve prognosis and may alleviate the adverse effects of adjuvant therapy. To assess effects of physical activity interventions after adjuvant therapy for women with breast cancer. We searched the Cochrane Breast Cancer Group (CBCG) Specialised Registry, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Physiotherapy Evidence Database (PEDro), SPORTDiscus, PsycINFO, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform, on 18 September 2015. We also searched OpenGrey and Healthcare Management Information Consortium databases. We searched for randomised and quasi-randomised trials comparing physical activity interventions versus control (e.g. usual or standard care, no physical activity, no exercise, attention control, placebo) after adjuvant therapy (i.e. after completion of chemotherapy and/or radiation therapy, but not hormone therapy) in women with breast cancer. Two review authors independently selected studies, assessed risk of bias, and extracted data. We contacted trial authors to ask for additional information when needed. We calculated an overall effect size with 95% confidence intervals (CIs) for each outcome and used GRADE to assess the quality of evidence for the most important outcomes. We included 63 trials that randomised 5761 women to a physical activity intervention (n = 3239) or to a control (n = 2524). The duration of interventions ranged from 4 to 24 months, with most lasting 8 or 12 weeks (37 studies). Twenty-eight studies included aerobic exercise only, 21 involved aerobic

    Purpose: A retrospective analysis to determine differences in survival of patients with pancreatic aden carcinoma treated by radical surgery with and without adjuvant radiation therapy. Methods and Materials: Between 1980 and 1995, 249 patients with pancreatic tumors were identified at the Medical College of Ohio. Forty-four of these patients underwent radical surgical procedures with curative intent. These patients were divided into four groups according to treatment: surgery alone (n = 14), surgery plus intraoperative radiation therapy (IORT) (n = 6), surgery plus external beam radiation therapy (EBRT) (n = 14), or surgery plus both IORT and EBRT (n = 10). Outcome and survival were analyzed among the four groups. Results: The median survival time of patients treated with radical surgery alone was 6.5 months. The median survival time for the surgery plus IORT group was 9 months; however, 33.3% (two of six) of these patients survived longer than 5 years. This survival pattern was borderline significantly better than that for the surgery alone group (p = 0.0765). The surgery plus EBRT and the surgery plus IORT and EBRT groups had median survival times of 14.5 and 17.5 months, respectively. These were significantly better than that of the surgery alone group (p = 0.0004 and p = 0.0002, respectively). The addition of radiation therapy did not affect the treatment complication rate. Conclusion: The survival of patients who were treated with radical surgery alone was significantly poorer than that of patients who received adjuvant radiation therapy. These results are consistent with other studies in the literature. Patients treated with all three modalities (surgery, IORT, and EBRT) displayed the best median survival time

    authors independently extracted data and assessed trial quality. Disagreements were resolved by discussion or a third reviewer. Random effects meta-analyses and sub-group analyses were conducted. Five randomised controlled trials (RCTs), enrolling 1277 women, with 46 to 110 months follow-up, met our inclusion criteria. These trials had low risk of bias. Meta-analysis of three trials with adequate data, assessing 1008 women, indicated that women who received adjuvant platinum-based chemotherapy had better overall survival (OS) than those who did not (hazard ratio (HR) 0.71; 95% CI 0.53 to 0.93). Likewise, meta-analysis of four trials with adequate data, assessing 1170 women, indicated that women who received adjuvant chemotherapy had better progression-free survival (PFS) than those who did not (HR 0.67; 95% CI 0.53 to 0.84). The trials included in these meta-analyses gave consistent estimates of the effects of chemotherapy.Sub-group analysis suggested that women who had optimal surgical staging of their disease were unlikely to benefit from adjuvant chemotherapy (HR for OS 1.22; 95% CI 0.63 to 2.37) whereas those who had sub-optimal staging did (HR for OS 0.63; 95% CI 0.46 to 0.85). One trial showed a benefit from adjuvant chemotherapy among women at high risk (HR for OS 0.48; 95% CI 0.32 to 0.72) but not among those at low risk (HR for OS 0.95; 95% CI 0.54 to 1.66). However, these sub-group findings could be due to chance. Adjuvant platinum based chemotherapy is effective in prolonging the survival of the majority of patients who are assessed as having early stage epithelial ovarian cancer. However, even given the limits of sub-group analyses, there is strong evidence that optimal surgical staging identifies patients who have either little or nothing to gain from adjuvant chemotherapy. Taken together with the lack of a survival advantage seen in patients with "low-risk" cancers in the ICON1 trial, it appears safe to withhold adjuvant chemotherapy from optimally staged

    Few data are available on compliance and safety of adjuvant chemotherapy when indicated in elderly breast cancer patients; CMF (cyclophosphamide, methotrexate, fluorouracil) can be reasonably considered the most widely accepted standard of treatment. We retrospectively reviewed compliance and safety of adjuvant CMF in patients older than 60. The treatment was indicated if patients had no severe comorbidity, a high-risk of recurrence, and were younger than 75. Toxicity was coded by NCI-CTC. Toxicity and compliance were compared between two age subgroups (<65, ≥ 65) by Fisher exact test and exact Wilcoxon rank-sum test. From March 1991 to March 2002, 180 patients were identified, 100 older than 60 and younger than 65, and 80 aged 65 or older. Febrile neutropenia was more frequent among older patients (p = 0.05). Leukopenia, neutropenia, nausea, cardiac toxicity and thrombophlebitis tended to be more frequent or severe among elderlies, while mucositis tended to be more evident among younger patients, all not significantly. Almost one half (47%) of the older patients receiving concomitant radiotherapy experienced grade 3–4 haematological toxicity. Compliance was similar in the two groups, with 6 cycles administered in 86% and 79%, day-8 chemotherapy omitted at least once in 36% and 39%, dose reduction in 27% and 38%, prolonged treatment duration (≥ 29 weeks) in 10% and 11% and need of G-CSF in 9% and 18%, among younger and older patients, respectively. Our data show that, in a highly selected population of patients 65 or more years old, CMF is as feasible as in patients older than 60 and younger than 65, but with a relevant burden of toxicity. We suggest that prospective trials in elderly patients testing less toxic treatment schemes are mandatory before indicating adjuvant chemotherapy to all elderly patients with significant risk of breast cancer recurrence

    Aim: The assessment of the compliance with consensus recommendations for adjuvant radiation therapy among women with breast cancer. The study is based on data obtained in a population-based cohort-study, which was performed to evaluate the quality of health care for patients with breast cancer. Patients and Methods: About one million inhabitants live in the study region Eastern Thuringia. 2,031 cases with invasive breast cancer without distant metastasis (MO) or inflammatory spread were registered from 1995 to 2000. Out of these 1,700 with complete documentation of covariates were included in multivariate analysis. To examine the simultaneous influence of all clinical factors and 'caseload' on the likelihood to receive adjuvant radiation therapy a logistic regression model was fitted for radiation therapy after mastectomy. In order to describe the impact of each individual clinic on treatment decision as 'caseload' was replaced by the clinics with more than 30 primary treatments. Results: Following breast conserving therapy (BCT) 90.6% of the patients received adjuvant radiation therapy. In the univariate analysis older age was negatively associated with the use of radiation therapy among women with BCT (Table 1). Furthermore, comorbid conditions were negatively associated with the use of radiation therapy. For all other cofactors no associations were found. Subsequent to mastectomy 33.0% of the women underwent radiation therapy (Table 2). Associations between the use of radiation therapy and age, tumor category, number of positive lymph nodes, multiple tumors, histologic differentiation grade, residual tumor as well as hormone receptor status were found. In the multivariate analysis only older age (≥70 years) was identified as negative indicator for the utilization of radiation therapy. Among patients with mastectomy increasing tumor size was a positive predictor on radiation therapy (Table 3). In addition more than three positive lymph nodes, multiplicity, poor

    Purpose: To report outcomes for patients with resected pancreas cancer treated with an adjuvant regimen consisting of gemcitabine-based combination chemotherapy followed by capecitabine and radiation. Patients and Methods: We performed a retrospective review of a series of patients treated at a single institution with a common postoperative adjuvant program. Between January 2002 and August 2006, 43 resected pancreas cancer patients were offered treatment consisting of 4, 21-day cycles of gemcitabine 1 g/m 2 intravenously over 30 min on Days 1 and 8, with either cisplatin 35 mg/m 2 intravenously on Days 1 and 8 or capecitabine 1500 mg/m 2 orally in divided doses on Days 1-14. After completion of combination chemotherapy, patients received a course of radiotherapy (54 Gy) with concurrent capecitabine (1330 mg/m 2 orally in divided doses) day 1 to treatment completion. Results: Forty-one patients were treated. Median progression-free survival for the entire group was 21.7 months (95% confidence interval 13.9-34.5 months), and median overall survival was 45.9 months. In multivariate analysis a postoperative CA 19-9 level of ≥180 U/mL predicted relapse and death. Toxicity was mild, with only two hospitalizations during adjuvant therapy. Conclusions: A postoperative adjuvant program using combination chemotherapy with gemcitabine and either cisplatin or capecitabine followed by radiotherapy with capecitabine is tolerable and efficacious and should be considered for Phase III testing in this group of patients.

    Purpose Fluorouracil plus leucovorin (FU + LV) adjuvant chemotherapy reduced the risk of recurrence and death across all time points in a pooled analysis of 20,898 patients with colon cancer from 18 randomized studies. The impact of oxaliplatin added to FU + LV on the time course of recurrence and survival remains unknown. Patients and Methods A total of 12,233 patients enrolled to the randomized trials C-07, C-08, N0147, MOSAIC (Adjuvant Treatment of Colon Cancer), and XELOXA (Adjuvant XELOX) were pooled to examine the impact of oxaliplatin and tumor-specific factors on the time course of recurrence and death. For each end point, continuous-time risk was modeled over 6 years post treatment in all oxaliplatin-treated patients and patients concurrently randomized to FU + LV with or without oxaliplatin; the latter analyses supported time-dependent treatment comparisons. Results Addition of oxaliplatin significantly reduced the risk of recurrence within the first 14 months post treatment for patients with stage II disease and within the first 4 years for patients with stage III disease. Oxaliplatin also significantly reduced risk of death from 2 to 6 years post treatment for patients with stage III disease, with no differences in timing of outcomes between treatment groups (ie, oxaliplatin did not simply postpone recurrence or death compared with FU + LV alone). Patients with stage II disease receiving oxaliplatin did not exhibit a significant reduction in risk of death in the first 6 years post treatment. Recurrence risk peaked near 14 months for both treatments, and risk of recurrence and death increased with increased tumor and nodal burden. Conclusions These analyses support the addition of oxaliplatin to fluoropyrimidine-based adjuvant therapy in patients with stage III disease and underscore the need for adequate surveillance of patients with colon cancer during the first 3 years after adjuvant therapy.

    With the results of studies on the timing of adjuvant treatment, it currently appears that adjuvant treatment should be initiated as soon as possible. Breast conserving surgery and oncoplastic surgery is being used with increasing frequency. Therefore, studies about whether or not these applications delay the adjuvant treatment are needed. The aim of this study was to determine the time period needed for adjuvant chemotherapy and radiotherapy of the patients with breast cancer and to reveal associated factors related to the patient, tumor, and surgical technique. Two hundred eighty patients with breast cancer who had surgery and were given adjuvant treatments in our clinic were included in the study. Age, body mass index, concomitant diseases, smoking habits, menopausal status, neoadjuvant treatments, tumor characteristics, surgical technique, and surgical complications were recorded. The time period between surgery and initiation of chemotherapy and radiotherapy, the number of chemotherapy cycles, and the duration of chemotherapy and radiotherapy were calculated. The numbers of patients who had modified radical mastectomy, breast conserving surgery, and oncoplastic surgery were 155 (55%), 47 (16.8%), and 78 (27.9%), respectively. The mean (SD) time period needed for chemotherapy administration was 19.5 ± 4.2 days (range, 13-41 days) and 3.9 ± 0.9 months for radiotherapy. Early wound complication of breast surgery was the only factor that delayed the adjuvant chemotherapy (P = .001). It has been well known that the time period between surgical treatment of breast cancer and adjuvant treatment affects survival. In our study, it has been shown that the surgical techniques used in breast and axillary surgery do not delay the initiation of adjuvant treatments. The adjuvant treatments of the patients who had oncoplastic surgery and breast conserving surgery were not delayed. The cooperation between the disciplines for the initiation of adjuvant treatments is important

    Randomized trials demonstrating the benefits of chemotherapy in patients with American Joint Committee on Cancer stage III colon cancer underrepresent persons aged ≥ 75 years. The generalizability of these studies to a growing elderly population remains unknown. Using the California Cancer Registry for 1994 through 2008, the authors conducted a population-based study of postcolectomy patients aged 50 years to 94 years with stage III (N1M0) colon adenocarcinoma. A 2-sided chi-square test and Cochran-Armitage test for trend were used to compare patient and tumor characteristics associated with receipt of chemotherapy across age groups. Multivariate regression was used to assess the association between older age and receipt of chemotherapy. Kaplan-Meier methods and Cox proportional hazards modeling were used to evaluate the association between chemotherapy and mortality, with propensity score adjustment. Approximately 44% (12,382 patients) of the study cohort was aged ≥ 75 years. Persons aged ≥ 75 years were found to be less likely to have received adjuvant chemotherapy than those aged colon cancer in the elderly. Copyright © 2012 American Cancer Society.

    Surgery followed by adjuvant chemotherapy has been the standard of care for the treatment of stage III colon cancer since the early 1990's. Despite this, large proportions of patients do not receive adjuvant chemotherapy. We aimed to identify physicians' and patients' reasons for treatment decisions. A retrospective population based study was conducted that included all surgically treated stage III colon cancer patients diagnosed in Alberta between 2002 and 2005 who had an oncologist-consult to discuss post-surgical treatment options. Patient demographics and stage were obtained from the Alberta Cancer Registry. Chart reviews were conducted to extract treatment details, the oncologists' reasons for not recommending chemotherapy, and patients' reasons for refusing chemotherapy. The number and proportion of patients who were not recommended or refused chemotherapy were calculated. A total of 613 patients had surgery followed by an oncologist-consult. Overall, 168 (27%) patients did not receive chemotherapy. It was not recommended for 111 (18%) patients; the most frequent reason was presence of one or more co-morbidities (34%) or combination of co-morbidity and age or frailty (22%). Fifty-eight (9%) patients declined chemotherapy, 22% of whom declined due to concerns about toxicity. Some co-morbidities are clinical indications for not receiving adjuvant chemotherapy, however, the high percentage of patients who were not recommended adjuvant chemotherapy due to co-morbidities according to clinical notes but who had a low Charlson co-morbidity score suggests variation in practice patterns of consulting oncologists. In addition, patients' reasons for refusing treatment need to be systematically assessed to ensure patients' preferences and treatment benefits are properly weighed when making treatment decisions.

    The effects of radiation therapy and adjuvant chemoimmunotherapy on the immune competence of patients with breast cancer were investigated. The tests performed included intradermal tuberculin tests, T- and B-lymphocyte counts, and lymphocyte blast transformation tests; phytohemagglutinin (PHA), concanavalin A (ConA) and pokeweed mitogen (PMW) were used as mitogens. Enhancement in lymphocyte proliferative response to mitogenic stimulation by PHA and PMW was seen in patients after 3 courses of chemotherapy + levamisole, whereas irradiation given after chemotherapy caused long-lasting depression in response to PHA and PWM (not significant). T-lymphocyte counts were also lower after irradiation than after chemoimmunotherapy. Clinically, the 16 patients treated with radiation therapy after chemotherapy exhibited a higher recurrence rate than the 24 patients treated first by irradiation. Enhanced reactivity to tuberculin tests occurred generally in patients receiving a planned treatment including irradiation, chemotherapy (5-fluorouracil, doxorubicin, cyclophosphamide) and levamisole. Enhancement of reactivity was seen more often in patients who had not relapsed.

    Purpose: During adjuvant radiotherapy (RT) for rectal cancer, patients receiving 5-fluorouracil (5-FU) by protracted venous infusion have a higher risk of diarrhea than have patients receiving bolus 5-FU. Toxicity from a previously reported randomized clinical trial was analyzed to quantify the difference in this risk. Additionally, the persistence of diarrhea after RT was analyzed. Methods and Materials: A total of 656 patients were eligible. Patients with T3-4 N0-2 M0 or T1-2 N1-2 M0 resected, high-risk rectal cancer were randomly allocated to receive 5-FU by either protracted venous infusion or bolus during RT (50.4-54.0 Gy). Two cycles of bolus 5-FU were given before and after RT. One-half of the first 445 patients were also randomly allocated to receive lomustine in conjunction with the bolus 5-FU. The incidence and severity of diarrhea in relation to patient and treatment characteristics were evaluated. Results: The rate of diarrhea was significantly greater in patients receiving 5-FU by protracted venous infusion than in patients receiving bolus 5-FU; the difference was most pronounced for Grade 3 (severe) diarrhea (21% versus 13%, p=0.007). The incidence and magnitude of diarrhea before and after RT were similar. Patients treated with an anterior resection had a higher rate of severe or life-threatening diarrhea than did patients treated with an abdominoperineal resection (31% vs. 12%, p<0.001). Conclusions: During pelvic RT, patients who receive 5-FU by protracted venous infusion rather than by bolus have a higher risk of severe or life-threatening diarrhea during RT. This risk does not appear to persist during chemotherapy after completion of pelvic RT

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

    To estimate the cumulative randomized evidence for the overall incidence of bisphosphonates induced jaw osteonecrosis in adjuvant treatment of breast cancer. Systematic review and meta-analysis of randomized clinical trials. Trials were located through PubMed, ISI, Cochrane Library, and major cancer scientific meetings searches. We identified 15 studies reporting data on osteonecrosis of the jaw. A total of 10,694 randomized women were included, of whom 5,312 received bisphosphonates and 5,382 received either placebo or no treatment. Osteonecrosis of the jaw was a rare event, occurring in 13 (0.24%) of the 5,312 patients receiving bisphosphonates, and in one of the 5,382 patients in the control group. All the 13 events of osteonecrosis of the jaw reported among bisphosphonates arms occur in patients undergoing treatment with zoledronic acid (13/3,987, 0.33%). No events of osteonecrosis of the jaw were reported among patients randomized to receive clodronate (n = 669), pamidronate (n = 460), risedronate (n = 171), and ibandronate (n = 25); however, these samples were too small to be able to rule out the condition. Treatment with zoledronic acid was significantly associated to the occurrence of osteonecrosis of the jaw (OR = 3.23, 95% CI = 1.7-8) compared with no use. No significant between-study heterogeneity was observed. Despite use of zoledronic acid is associated to a higher number of events compared with no use, the osteonecrosis of the jaw during the adjuvant treatment of breast cancer is a rare event. At current dosage, adjuvant use of bisphosphonates in breast cancer treatment is safe.

Previous research has indicated that patient refusal of treatment is a contributing factor. This study aimed to identify potential barriers to adjuvant chemotherapy use in older patients by examining the associations between patient age, factors influencing chemotherapy treatment decisions, and preferences for information and decision-making involvement.Patients and methods: Sixty-eight patients who underwent surgery for colorectal cancer in Sydney, Australia, within the previous 24 months completed a self-administered survey.Results: Fear of dying, health status, age, quality of life, and understanding treatment procedures and effects were significantly more important to older patients (aged ≥65 years than younger patients in deciding whether to accept chemotherapy (all P < 0.05. Reducing the risk of cancer returning and physician trust were important factors for all patients. Practical barriers such as traveling for treatment and cost were rated lowest. Older patients preferred less information and involvement in treatment decision making than younger patients. However, 60% of the older group wanted detailed information about chemotherapy, and 83% wanted some involvement in decision making. Those preferring less information and involvement still rated many factors as important in their decision making, including understanding treatment procedures and effects.Conclusion: A range of factors appears to influence

    Background Cisplatin and vinorelbine given intravenously is a well-established adjuvant chemotherapy regimen after surgery for early non-small cell lung cancer. However, few validated alternatives exist when cisplatin is not indicated or tolerated. Carboplatin is frequently used in this setting. We evaluated the 5-year overall survival, progression-free survival and toxicity in patients treated for stage IB to IIIB resected non-small cell lung cancer receiving adjuvant carboplatin-based chemotherapy compared to cisplatin in association with vinorelbine. Methods Single-center retrospective study of patients having received adjuvant chemotherapy between January 2004 and December 2013 at the oncology clinic at Institut Universitaire de Cardiologie et de Pneumologie de Québec (Canada). Three sub-groups, cisplatin/vinorelbine, carboplatin/vinorelbine and the substitution of cisplatin/vinorelbine for carboplatin/vinorelbine (cisplatin/vinorelbine/carboplatin/vinorelbine), were studied during treatment. Results One hundred twenty-seven patients were included in this study. The median PFS was not significantly different, with 50.4 months for cisplatin/vinorelbine, 57.3 months for cisplatin/vinorelbine/carboplatin/vinorelbine and not yet achieved for the carboplatin/vinorelbine group ( p = 0.80). Overall survival also did not differ significantly between the three groups. The 5-year overall survival rates were 66% in cisplatin/vinorelbine group, 55% in carboplatin/vinorelbine group and 70% in cisplatin/vinorelbine/carboplatin/vinorelbine group ( p = 0, 95). No differences were noted between groups concerning high-grade hematologic toxicity. Conclusions Although the effectiveness and hematologic toxicity are comparable between cisplat in and carboplatin in the adjuvant treatment of resected non-small cell lung cancer, the results obtained corroborate the practice used at our oncology clinic. Nevertheless, more prospective studies would be needed to confirm these

    The aim of this study was to describe the impact of postoperative adjuvant treatment modalities and identify risk factors associated with recurrence and survival rates in women diagnosed with early stage type II endometrial cancer and carcinosarcoma. In this retrospective study, patients diagnosed with early stage (stages I-II) carcinosarcoma and type II endometrial cancer were reviewed. All women underwent comprehensive surgical staging. Postoperative treatment options of chemotherapy (CT), radiotherapy (RT), observation (OBS) and chemotherapy-radiotherapy (CT-RT) combination were compared in terms of recurrence and survival outcome. In CT-RT treatment arm, recurrence rate was found as 12.5% and this result is significantly lower than the other treatment approaches (P = 0.01 CT alone: 33.3%, RT alone: 26.7%, OBS: 62.5%). Three-year disease free survival(DFS) rate and overall survival (OS) rate were statistically higher for the group of women treated with combination of CT-RT (92-95%) compared to the women treated with RT alone (65-72%), treated with CT alone (67-74%) and women who received no adjuvant therapy (38-45%). The multivariate analysis revealed that carcinosarcoma histology was associated with shortened DFS and OS (P = 0.001, P = 0.002). On the other hand, being at stage Ia (P = 0.01, P = 0.04) and receiving adjuvant treatment of CT-RT combination (P = 0.005, P = 0.002) appeared to lead to increased DFS and OS rates. We identified that a combination treatment of chemotherapy and radiotherapy is superior compared to other postoperative adjuvant treatment approaches concerning PFS, OS and recurrence rates in stages I-II of type II endometrial cancers and uterine carcinosarcoma. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Elevated Microsatellite Alterations at Selected Tetranucleotide repeats (EMAST is a genetic signature found in up to 60% of colorectal cancers (CRCs that is caused by somatic dysfunction of the DNA mismatch repair (MMR protein hMSH3. We have previously shown in vitro that recognition of 5-fluorouracil (5-FU within DNA and subsequent cytotoxicity was most effective when both hMutSα (hMSH2-hMSH6 heterodimer and hMutSβ (hMSH2-hMSH3 heterodimer MMR complexes were present, compared to hMutSα > hMutSβ alone. We tested if patients with EMAST CRCs (hMutSβ defective had diminished response to adjuvant 5-FU chemotherapy, paralleling in vitro findings. We analyzed 230 patients with stage II/III sporadic colorectal cancers for which we had 5-FU treatment and survival data. Archival DNA was analyzed for EMAST (>2 of 5 markers mutated among UT5037, D8S321, D9S242, D20S82, D20S85 tetranucleotide loci. Kaplan-Meier survival curves were generated and multivariate analysis was used to determine contribution to risk. We identified 102 (44% EMAST cancers. Ninety-four patients (41% received adjuvant 5-FU chemotherapy, and median follow-up for all patients was 51 months. Patients with EMAST CRCs demonstrated improved survival with adjuvant 5FU to the same extent as patients with non-EMAST CRCs (P<0.05. We observed no difference in survival between patients with stage II/III EMAST and non-EMAST cancers (P = 0.36. There is improved survival for stage II/III CRC patients after adjuvant 5-FU-based chemotherapy regardless of EMAST status. The loss of contribution of hMSH3 for 5-FU cytotoxicity may not adversely affect patient outcome, contrasting patients whose tumors completely lack DNA MMR function (MSI-H.

    To explore the role of adjuvant chemotherapy for patients with ypT0-2N0 rectal cancer treated by preoperative chemoradiation therapy (PCRT) and radical resection. A national consortium of 10 institutions was formed, and patients with ypT0-2N0 mid- and low-rectal cancer after PCRT and radical resection from 2004 to 2009 were included. Patients were categorized into 2 groups according to receipt of additional adjuvant chemotherapy: Adj CTx (+) versus Adj CTx (-). Propensity scores were calculated and used to perform matched and adjusted analyses comparing relapse-free survival (RFS) between treatment groups while controlling for potential confounding. A total of 1016 patients, who met the selection criteria, were evaluated. Of these, 106 (10.4%) did not receive adjuvant chemotherapy. There was no overall improvement in 5-year RFS as a result of adjuvant chemotherapy [91.6% for Adj CTx (+) vs 87.5% for Adj CTx (-), P=.18]. There were no differences in 5-year local recurrence and distant metastasis rate between the 2 groups. In patients who show moderate, minimal, or no regression in tumor regression grade, however, possible association of adjuvant chemotherapy with RFS would be considered (hazard ratio 0.35; 95% confidence interval 0.14-0.88; P=.03). Cox regression analysis after propensity score matching failed to show that addition of adjuvant chemotherapy was associated with improved RFS (hazard ratio 0.81; 95% confidence interval 0.39-1.70; P=.58). Adjuvant chemotherapy seemed to not influence the RFS of patients with ypT0-2N0 rectal cancer after PCRT followed by radical resection. Thus, the addition of adjuvant chemotherapy needs to be weighed against its oncologic benefits. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Many adjuvant trials have been undertaken in an attempt to reduce the risk of recurrence among patients who undergo surgical resection for locally advanced renal cancer. However, no clear benefit has been identified to date. This systematic review was conducted to examine the exact role of adjuvant therapy in renal cancer setting. Methods Randomized controlled trials were searched comparing adjuvant therapy (chemotherapy, vaccine, immunotherapy, biochemotherapy versus no active treatment after surgery among renal cell cancer patients. Outcomes were overall survival (OS, disease-free survival (DFS, and severe toxicities. Risk ratios (RR, hazard ratios (HR and 95% confidence intervals were calculated using a fixed-effects meta-analysis. Heterogeneity was measured by I2. Different strategies of adjuvant treatment were evaluated separately. Results Ten studies (2,609 patients were included. Adjuvant therapy provided no benefits in terms of OS (HR 1.07; 95%CI 0.89 to 1.28; P = 0.48 I2 = 0% or DFS (HR 1.03; 95%CI 0.87 to 1.21; P = 0.77 I2 = 15% when compared to no treatment. No subgroup analysis (immunotherapy, vaccines, biochemotherapy and hormone therapy had relevant results. Toxicity evaluation depicted a significantly higher frequency of serious adverse events in the adjuvant group. Conclusions This analysis provided no support for the hypothesis that the agents studied provide any clinical benefit for renal cancer patients although they increase the risk of toxic effects. Randomized trials are underway to test targeted therapies, which might open a new therapeutic frontier. Until these trials yield results, no adjuvant therapy can be recommended for patients who undergo surgical resection for renal cell cancer.

    Chemotherapy is associated with acute and long-term cardiotoxicity. To date, risk assessment has primarily focused on the heart; however, recent findings suggest that vascular and autonomic function may also be compromised. Whether this occurs during chemotherapy treatment remains unknown. Therefore, the present study evaluated carotid artery stiffness, cardiovagal baroreflex sensitivity (cBRS), and heart rate variability (HRV) in cancer patients currently being treated with adjuvant chemotherapy. Eleven current cancer patients receiving adjuvant chemotherapy and eleven matched (1:1) controls were studied. Carotid artery stiffness was assessed via 2D ultrasonography. cBRS was assessed from the spontaneous changes in beat-to-beat time series of R-R interval and systolic blood pressure via the cross correlation technique. HRV was assessed using the SDNN (standard deviation of RR intervals) and low (LF) and high (HF) power frequencies. Carotid artery β-Stiffness was significantly higher in the cancer patients compared to control participants (8.0{plus minus}0.8 vs 6.3{plus minus}0.6 U, respectively; P=0.02). cBRS was lower in the cancer patients compared to controls (4.3{plus minus}0.7 vs 10.7{plus minus}1.9 msec mmHg -1 , respectively; P=0.01) and all indices of HRV were lower in the cancer patients (SDNN, P=0.02; LF, P=0.01; HF, P=0.02). There was no significant correlation between β-Stiffness and cBRS (P = 0.4). However, LF power was significantly correlated with cBRS (r=0.66, P<0.001). Compared to matched healthy controls, cancer patients undergoing chemotherapy demonstrated a significantly higher arterial stiffness and lower cardiovagal baroreflex sensitivity. The previously reported adverse effects of chemotherapy on the heart appear to also influence other aspects of cardiovascular health.

    Rectal cancer can be considered a broad-spectrum disease, where the surgeon, radiation oncologist and medical oncologist have a peculiar and specific place in order to work harmoniously as a good orchestra. The reality in common general hospitals is far from that of comprehensive cancer centers, particularly for postoperative approaches. The adjuvant therapy of rectal cancer is not codified worldwide, and it is strongly dependent on preoperative staging procedures, surgeon's acts and pathologist's decisions. Starting from our 10-year experience, we analyzed the various steps of postoperative approaches, defining possible decision errors, the incongruity of some attitudes, and the lack of knowledge of recent achievements of science in this disease. A total of 194 patients with advanced surgically removed rectal cancer (pT3-4 pN0-any pT pN+) treated with postoperative radio(chemo)therapy was reviewed retrospectively. Anterior resection was performed in 126, abdominoperineal resection in 48, and other surgical procedures in 20 patients. Irradiation was conducted with a single daily fraction of 1.8 Gy until 45 Gy, and chemotherapy consisted of the combination of 5-fluorouracil and folinic acid (Machover schedule): 47% of patients with positive nodes did not receive chemotherapy. Five-year overall survival was 60.6% and relapse-free survival was 55.5%. The main prognostic factors were pathological T and N stages. The principal route of progression was distant metastases. Acute toxicity was severe in 1 case (drug toxic hepatitis) and very severe in 16 patients, and late severe sequelae appeared in 13 patients. The outcome of rectal cancer patients has not changed during the last decade, and this was confirmed in our study. The improvement of radiotherapy techniques has reduced the adverse acute and late toxicity. The best postsurgical approach for pT3pN0 cancer remains unsolved, as the good chemotherapy combination and the real solution could be the application of a new

    The incidence of new primary cancers was evaluated in 3538 postmenopausal patients who had received surgical treatment for primary breast cancer. Of these patients, 1828 with a low risk of recurrence received no further treatment. High-risk patients were randomly assigned to one of two groups. The first group (n = 846) received postoperative radiotherapy, while the second group (n = 864) received radiotherapy plus tamoxifen at a dose of 30 mg given daily for 48 weeks. The median observation time was 7.9 years. In comparison with the number of new cancers in the general population, the number of new cancers in the three groups was elevated mostly due to a high number of cancers of the contralateral breast and of colorectal cancers in the high-risk groups. The cumulative risk of nonlymphatic leukemia was increased among patients who received postoperative radiotherapy (P = .04). Cancer incidence in the high-risk tamoxifen-treated group relative to that in the high-risk group not treated with tamoxifen was not significant (1.3). No protective effect of tamoxifen on the opposite breast was seen (rate ratio for breast cancer = 1.1), but a tendency to an elevated risk of endometrial cancer was observed (rate ratio = 3.3; 95% confidence interval = 0.6-32.4). Continued and careful follow-up of women treated with tamoxifen is necessary to clarify the potential cancer-suppressive or cancer-promoting effects of this drug

    Purpose: Long-term survival rates for patients with resected pancreatic ductal adenocarcinoma (PDAC) have stagnated at 20% for more than a decade, demonstrating the need to develop novel adjuvant therapies. Gemcitabine-erlotinib therapy has demonstrated a survival benefit for patients with metastatic PDAC. Here we report the first phase 2 study of erlotinib in combination with adjuvant chemoradiation and chemotherapy for resected PDAC. Methods and Materials: Forty-eight patients with resected PDAC received adjuvant erlotinib (100 mg daily) and capecitabine (800 mg/m{sup 2} twice daily Monday-Friday) concurrently with intensity modulated radiation therapy (IMRT), 50.4 Gy over 28 fractions followed by 4 cycles of gemcitabine (1000 mg/m{sup 2} on days 1, 8, and 15 every 28 days) and erlotinib (100 mg daily). The primary endpoint was recurrence-free survival (RFS). Results: The median follow-up time was 18.2 months (interquartile range, 13.8-27.1). Lymph nodes were positive in 85% of patients, and margins were positive in 17%. The median RFS was 15.6 months (95% confidence interval [CI], 13.4-17.9), and the median overall survival (OS) was 24.4 months (95% CI, 18.9-29.7). Multivariate analysis with adjustment for known prognostic factors showed that tumor diameter >3 cm was predictive for inferior RFS (hazard ratio, 4.01; P=.001) and OS (HR, 4.98; P=.02), and the development of dermatitis was associated with improved RFS (HR, 0.27; P=.009). During CRT and post-CRT chemotherapy, the rates of grade 3/4 toxicity were 31%/2% and 35%/8%, respectively. Conclusion: Erlotinib can be safely administered with adjuvant IMRT-based CRT and chemotherapy. The efficacy of this regimen appears comparable to that of existing adjuvant regimens. Radiation Therapy Oncology Group 0848 will ultimately determine whether erlotinib produces a survival benefit in patients with resected pancreatic cancer.

    We aimed to investigate a practical profile of MAC30 on chemotherapeutic response in gastric cancer (GC). We elected 87 GC patients receiving platinum-based chemotherapy in this study. MAC30 levels in tumor and adjuvant nontumor tissues were confirmed via reverse transcription-PCR to identify the clinical profile in GC and the correlation with therapeutic response. We found elevated MAC30 in GC compared with the matched adjacent nontumor tissues. GC with enhanced MAC30 exhibited poorer survival by Kaplan-Meier analysis and poor response to adjuvant platinum-based chemotherapy. A multivariate analysis showed that MAC30 was an independent prognostic factor of overall survival in GC receiving platinum-based chemotherapy. MAC30 could play as a potential biomarker for prognosis of GC with platinum-based chemotherapy.

    Treatment with aromatase inhibitors for postmenopausal women with breast cancer has been shown to reduce or obviate invasive procedures such as hysteroscopy or curettage associated with tamoxifen-induced endometrial abnormalities. The side effect of upfront aromatase inhibitors, diminished estrogen synthesis, is similar to that seen with the natural events of aging. The consequences often include vasomotor symptoms (hot flushes) and vaginal dryness and atrophy, which in turn may result in cystitis and vaginitis. Not surprisingly, painful intercourse (dyspareunia) and loss of sexual interest (decreased libido) frequently occur as well. Various interventions, both non-hormonal and hormonal, are currently available to manage these problems. The purpose of the present review is to provide the practitioner with a wide array of management options to assist in treating the sexual consequences of aromatase inhibitors. The suggestions in this review are based on recent literature and on the recommendations set forth both by the North American Menopause Association and in the clinical practice guidelines of the Society of Gynaecologists and Obstetricians of Canada. The complexity of female sexual dysfunction necessitates a biopsychosocial approach to assessment and management alike, with interventions ranging from education and lifestyle changes to sexual counselling, pelvic floor therapies, sexual aids, medications, and dietary supplements-all of which have been reported to have a variable, but often successful, effect on symptom amelioration. Although the use of specific hormone replacement-most commonly local estrogen, and less commonly, systemic estrogen with or without an androgen, progesterone, or the additional of an androgen in an estrogenized woman (or a combination)-may be highly effective, the concern remains that in patients with estrogen-dependent breast cancer, including those receiving anti-estrogenic adjuvant therapies, the use of these hormones may be

    The impact of radiotherapy on the survival of patients with locally advanced esophageal cancer (EC) is presently insufficiently explored. Thus, using data from the Surveillance, Epidemiology, and End Results (SEER) Registry, this study aimed to compare the survival rates of patients with lymph node (LN) positive EC who received curative resection and were treated by neoadjuvant and adjuvant radiotherapy (RT), respectively. Retrospectively collected data from the SEER database using all 18 SEER registries on patients that underwent esophagectomy for EC was evaluated. All patients with LN positive pathology who received either neoadjuvant or adjuvant RT and curative intent esophagectomy from 2004 to 2007 were included. A comparison of 5-year relative survival outcome among groups categorized by sex, race, age, histology, and tumor size was performed. A total of 933 patients were evaluated; 636 (69%) and 297 (31%) received RT in neoadjuvant and adjuvant setting respectively. Their overall 5-year relative survival rates were 32.8% (95% CI: 28.7-36.9) and 26.5% (95% CI: 21-32.3) (P=0.058). Patients in the neoadjuvant RT group who underwent curative resection for squamous cell carcinoma (SCC) of EC had an improved 5-year relative survival rate of 43.4% (95% CI: 32.5-53.8) compared to 26.5% (95% CI: 15.4-38.9) measured for the adjuvant RT group (P=0.03). The results further revealed a significant increase in the 5-year relative survival rates for stage T3 and Tx when RT was given in neoadjuvant setting compared to adjuvant RT group (T3 28.5% vs. 20.2%, P=0.011; Tx 46.3% vs. 8.9%, P=0.021). When the patients were grouped according to race, sex or age, or based on the timing of radiation relative to surgery, in the other histological or T stage groups, there were no statistically significant differences in the 5-year survival rates. Compared to adjuvant radiotherapy, neoadjuvant radiotherapy results in a better 5-year relative survival in patients with squamous cell

    Adjuvant chemotherapy has been known as a standard treatment for patients with resected colon cancer. However, in elderly colon cancer patients, the characteristics of patients are heterogeneous with regard to life expectancy and comorbidities. Thus, with regard to the effectiveness of adjuvant chemotherapy for colon cancer, it is difficult to extrapolate data of clinical trials from the younger into the older general population. Data for 382 elderly colon cancer patients were analyzed: 217 in Stage II and 165 in Stage III. The efficacy of adjuvant chemotherapy was evaluated in elderly colon cancer patients after a match by the propensity score method. For matched patients with Stage II colon cancer, there was no significant efficacy of adjuvant chemotherapy in the risk of death during all follow-up periods (P-value, 0.06-0.37). Though there was a tendency that the adjuvant chemotherapy reduces the death rate during the follow-up periods, it was not statistically significant. In the case of Stage III, the adjuvant chemotherapy was significantly effective in matched patients for 5-year (hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.30-0.90) and overall survival (HR, 0.56; 95% CI, 0.34-0.94). Adjuvant chemotherapy for elderly patients with Stage II colon cancer is not effective, whereas elderly patients with Stage III with adjuvant chemotherapy appear to have a better survival rate in the general population.

    Few studies have examined the role of radiation therapy in advanced penile squamous cell carcinoma. We sought to evaluate the association of adjuvant pelvic radiation with survival and recurrence for patients with penile cancer and positive pelvic lymph nodes (PLNs) after lymph node dissection. Data were collected retrospectively across 4 international centers of patients with penile squamous cell carcinoma undergoing lymph node dissections from 1980 to 2013. Further, 92 patients with available adjuvant pelvic radiation status and positive PLNs were analyzed. Disease-specific survival (DSS) and recurrence were analyzed using the Kaplan-Meier method and multivariable Cox proportional hazards model. 43% (n = 40) of patients received adjuvant pelvic radiation after a positive PLN dissection. Median follow-up was 9.3 months (interquartile range: 5.2-19.8). Patients receiving adjuvant pelvic radiation had a median DSS of 14.4 months vs. 8 months in the nonradiation group, respectively (P = 0.023). Patients without adjuvant pelvic radiation were associated with worse overall survival (hazard ratio [HR] = 1.7; 95% CI: 1.01-2.92; P = 0.04) and DSS (HR = 1.9; 95% CI: 1.09-3.36; P = 0.02) on multivariable analysis. Median time to recurrence was 7.7 months vs. 5.3 months in the radiation and nonradiation arm, respectively (P = 0.042). Patients without adjuvant pelvic radiation was also independently associated with higher overall recurrence on multivariable analysis (HR = 1.8; 95% CI: 1.06-3.12; P = 0.03). Adjuvant pelvic radiation is associated with improved survival and decreased recurrence in this population of patients with penile cancer with positive PLNs. Copyright © 2017 Elsevier Inc.

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

    Aim The aim of our study was to evaluate stage III colon cancer patients discussed at a multidisciplinary team meeting to identify reasons for clinicians not recommending adjuvant chemotherapy and reasons for patients declining recommended chemotherapy. Methods A retrospective, single institution Australian study was conducted on all surgically managed stage III colon cancer patients diagnosed at the regional cancer centre at Toowoomba Hospital between July 2010 and December 2014. Reasons why adjuvant chemotherapy was not recommended by the multidisciplinary team or following referral to a medical oncologist and patients' reasons for refusing chemotherapy despite medical oncology recommendation were determined. Results One hundred and nine patients were suitable for evaluation. Overall, 72 (66.1%) received adjuvant chemotherapy. Chemotherapy was not recommended in 25 (23.4%) of patients, with the majority (68%) having more than one cited reason. Multiple comorbidities and advanced age were the most common reasons for non-recommendation ( p refusal were not detailed in the majority of patient charts (63.6%). Travel distance was not a factor in accepting or refusing chemotherapy. Conclusion Discussion at a multidisciplinary team meeting facilitates the identification of patients unsuitable for adjuvant treatment. The reasons for declining offered chemotherapy need to be assessed fully to ensure that patients' treatment preferences are balanced against the proven benefits of chemotherapy. Attendance at a regional cancer centre provides the opportunity for high standard care in the management of stage III colon cancer.

    Background: Survival rates after curative surgery for gastric cancer are disappointing. Therefore adjuvant therapeutic strategies are required. Aim: To analyze survival and side effects of treatment among gastric cancer patients treated with adjuvant chemoradiotherapy after curative resection of gastric adenocarcinoma. Material and methods: Retrospective review of medical records of 74 patients aged 20 to 74 years, treated with complete resection of gastric adenocarcinoma followed by adjuvant chemo radiation. Survival analysis was based on the records and information from the National Mortality Registry. Results: Five years survival fluctuated from 50% among patients in stage 1B to 25% among those is stage IV. Significant acute toxicity was observed in 23 patients (31%). No patients died due to acute toxicity. Eleven patients (16.4%) developed significant late toxicity, with two possible deaths related to treatment. Conclusions: Postoperative chemoradiotherapy is feasible in our experience. Continuos infusion of 5- fluoruracil is recommended to reduce toxicity

The primary objective of the study was to define parameters influencing the decision to prescribe adjuvant chemotherapy and the type of chemotherapy. Results Data for 1894 patients were available. 69.0% postmenopausal, 67.0% pT1, 22.3% pTmic/pT1a/pT1b, 61.0% pN0, 48.7% luminal A, 18.1% luminal B, 16.1% HER2 positive, 8.7% triple negative, 8.4% unknown. 57.8% received adjuvant chemotherapy: 38.1% of luminal A, 67.3% luminal B, 88.2% HER2-positive, 97.6% triple negative. Regimens administered: 9.1% CMF-like, 48.8% anthracyclines, 38.4% anthracyclines plus taxanes, 3.7% taxanes alone. Increasing pT/pN and, marginally, HER2-positive were associated with the prescription of anthracyclines plus taxanes. Suboptimal schedules (CMF-like or AC/EC or FEC-75 were prescribed in 37.3% receiving chemotherapy, even in HER2-positive and triple negative disease (36.5% and 34.0%, respectively. Conclusions This study showed an overprescription of adjuvant chemotherapy for early breast cancer, particularly referred to luminal A. pT, pN and, marginally, HER2 were the principal determinants for the choice of chemotherapy type. Suboptimal chemotherapy regimens were adopted in at least one third of HER2-positve and triple negative.

    Full Text Available Abstract Background The optimal time sequences for chemotherapy and radiation therapy after breast surgery for patients with breast cancer remains unknown. Most of published studies were done for early breast cancer patients. However, in Egypt advanced stages were the common presentation. This retrospective analysis aimed to assess the optimum sequence for our population. Methods 267 eligible patients planned to receive adjuvant chemotherapy [FAC] and radiotherapy. Majority of patients (87.6% underwent modified radical mastectomy while, 12.4% had conservative surgery. We divided the patients into 3 groups according to the sequence of chemotherapy and radiotherapy. Sixty-seven patients (25.1% received postoperative radiotherapy before chemotherapy [group A]. One hundred and fifty patients (56.2% were treated in a sandwich scheme (group B, which means that 3 chemotherapy cycles were given prior to radiotherapy followed by 3 further chemotherapy cycles. A group of 50 patients (18.7% was treated sequentially (group C, which means that radiotherapy was supplied after finishing the last chemotherapy cycle. Patients' characteristics are balanced between different groups. Results Disease free survival was estimated at 2.5 years, and it was 83.5%, 82.3% and 80% for patient receiving radiation before chemotherapy [group A], sandwich [group B] and after finishing chemotherapy [group C] respectively (p > 0.5. Grade 2 pneumonitis, which necessitates treatment with steroid, was detected in 3.4% of our patients, while grade 2 radiation dermatitis was 17.6%. There are no clinical significant differences between different groups regarded pulmonary or skin toxicities. Conclusion Regarding disease free survival and treatment toxicities, in our study, we did not find any significant difference between the different radiotherapy and chemotherapy sequences.

    Breast cancer (BC) is a major health problem in Egypt and worldwide. Its prognosis depends not only on tumor stage but also on tumor biology. To correlate the expression of Ki67 with the clinical outcomes of early hormone-receptor positive postmenopausal BC patients who are receiving tamoxifen. This cohort study included 70 patients. They were followed up for a minimum of 2 years. Ki67 was assessed on paraffin-embedded blocks using immunohistochemistry methods. The median Ki67 value was 22.5% (IQR, 10%-50%). Ki67 was significantly higher in patients with HER2 positive tumors compared to HER2 negative tumors. After a median follow up period of 53 months, 22 patients (31%) developed disease recurrence either loco-regional or distant in 5.7% and 30%, respectively. Recurrent patients had significantly higher tumor stage, nodal stage and Ki67 values compared to non-recurrent cases. The 2-, 3- and 5-year overall survival (OS) and disease-free survival (DFS) rates were 100% & 91%, 98% & 84% and 77% & 59%, respectively. DFS was significantly worse with higher TNM stage, lower ER expression and higher Ki67 values. OS was significantly worse in patients with Ki67 values ≥ 30%. Ki67 ≥ 30% was an independent predictor of recurrence, poor DFS and OS. High Ki67 expression is predictive of poor prognosis and of resistance to adjuvant tamoxifen therapy in postmenopausal BC. We recommend considering Ki67 as one of the risk factors that guide adjuvant treatment decisions. Copyright © 2013. Production and hosting by Elsevier B.V.

The histological type was classical seminoma (95%) and spermatocytes (5%). Diagnosis and staging were performed with testicular ultrasound, determination of tumor markers, computed tomography of abdomen - pelvis and chest radiographs. Radiotherapy: Patients were treated with 60 Co unit and a linear accelerator of 6 MV photons. Volumes: Group I: lumboaortic lymph node region and ipsilateral pelvis. Group II: lumboaortic only. Daily dose: 1.8 Gy, total dose: 30.6 Gy. Patient in supine position, 2 parallel fields and opposed, DFP: 80 cm, calculated from midplane. They were followed for 3 years with chest X-ray, CAT scan of abdomen and pelvis at 12 months and then a full clinical control 1 time per year. Results: We defined the rate of ipsilateral pelvic node recurrence (group I: 0% vs. Group II: 6.25%), progression at distance (group I: 8.3% vs. Group II: 0%) and global survival (GS) (group I: 100% vs. group II: 100%) at 3 years of follow up. Conclusions: Our result is similar to that published in the international literature. Given the small number of patients, no evidence of changes in GS with the addition of radiotherapy to ipsilateral pelvic node. Radiation therapy to lumboaortic lymph nodes is the usual treatment, being necessary to optimize the modality of radiotherapy (RC3D - IRMT) to reduce toxicity in a long term. (authors) [es

    PURPOSE: This study evaluates whether gene signatures for chemosensitivity for irinotecan and 5-fluorouracil (5-FU) derived from in vitro grown cancer cell lines can predict clinical sensitivity to these drugs. METHODS: To test if an irinotecan signature and a SN-38 signature could identify...... patients who benefitted from the addition of irinotecan to 5-FU, we used gene expression profiles based on cell lines and clinical tumor material. These profiles were applied to expression data obtained from pretreatment formalin fixed paraffin embedded (FFPE) tumor tissue from 636 stage III colon cancer...... patients enrolled in the PETACC-3 prospective randomized clinical trial. A 5-FU profile developed similarly was assessed by comparing the PETACC-3 cohort with a cohort of 359 stage II colon cancer patients who underwent surgery but received no adjuvant therapy. RESULTS: There was no statistically...

    A 54-year-old woman, who had underwent an adjuvant radiotherapy following the modified radical mastectomy in the left primary breast cancer in June 1988. She underwent second surgery and adjuvant radiotherapy (electronic radiotherapy) for recurrent breast cancer in the major pectoral muscle and received chemoimmunotherapy in May 1989. In May 1996 she complained of two ulcers of the chest wall. The ulcer biopsy findings was squamous cell carcinoma, and we diagnosed she fell the radiation-induced skin cancer. She underwent chest wall resection and reconstruction with vertical rectal abdominal musculocutaneous flap (V-RAM). However two months later her chest wall resection, she again got the recurrent squamous cell carcinoma in the right axillary lymph nodes and left pleura. The third radiotherapy and the chemotherapy with pepleomycin were uneffective on her recurrent cancer. And she died in March 1997. (author)

    The use of trastuzumab has proven to be a successful strategy in patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer; however, it is associated with an increased risk of cardiac dysfunction. We performed an up-to-date, comprehensive meta-analysis to clarify the risk of congestive heart failure (CHF) in patients with early breast cancer receiving different durations of adjuvant trastuzumab with the longest-term follow-up. Eligible studies included randomized control trials of HER2-positive early breast cancer patients with or without trastuzumab in adjuvant chemotherapy. Adequate reporting of CHF data were required for inclusion. Statistical analyses were conducted to calculate the overall incidence, relative risk (RR), and 95% confidence interval (CI) by use of a fixed-effects model. Six randomized control trials including 18,111 patients were identified. The overall incidence of high-grade CHF in patients treated with trastuzumab versus placebo was 1.44% (95% CI, 0.79%-2.64%) and the RR was 3.19 (95% CI, 2.03-5.02; p analysis, the difference in CHF incidence failed to achieve significance. The RR for 8 mg/kg trastuzumab (high dose) was greater than that for 4 mg/kg (low dose) (RR, 6.79, 95% CI, 2.03-22.72, p = .0001; versus RR, 2.64; 95% CI, 1.61-4.32; p = .002). Additionally, higher RRs were observed for patients receiving trastuzumab for 1 year (RR, 3.29; 95% CI, 2.07-5.25) and 2 years (RR, 9.54; 95%CI, 2.19-41.43), but not 9 weeks (RR, 0.50; 95% CI, 0.05-5.49) compared with control groups. No evidence of publication bias was observed. Adjuvant trastuzumab therapy was strongly associated with an increased risk of significant CHF in patients with early breast cancer, particularly in 2-year use. This comprehensive meta-analysis evaluated the risk of congestive heart failure with a usage profile of adjuvant trastuzumab in patients with early breast cancer. Before initiating treatment with trastuzumab, a risk-benefit analysis for

    Purpose The panel updated the American Society of Clinical Oncology (ASCO) adjuvant therapy guideline for resected non-small-cell lung cancers. Methods ASCO convened an update panel and conducted a systematic review of the literature, investigating adjuvant therapy in resected non-small-cell lung cancers. Results The updated evidence base covered questions related to adjuvant systemic therapy and included a systematic review conducted by Cancer Care Ontario current to January 2016. A recent American Society for Radiation Oncology guideline and systematic review, previously endorsed by ASCO, was used as the basis for recommendations for adjuvant radiation therapy. An update of these systematic reviews and a search for studies related to radiation therapy found no additional randomized controlled trials. Recommendations Adjuvant cisplatin-based chemotherapy is recommended for routine use in patients with stage IIA, IIB, or IIIA disease who have undergone complete surgical resections. For individuals with stage IB, adjuvant cisplatin-based chemotherapy is not recommended for routine use. However, a postoperative multimodality evaluation, including a consultation with a medical oncologist, is recommended to assess benefits and risks of adjuvant chemotherapy for each patient. The guideline provides information on factors other than stage to consider when making a recommendation for adjuvant chemotherapy, including tumor size, histopathologic features, and genetic alterations. Adjuvant chemotherapy is not recommended for patients with stage IA disease. Adjuvant radiation therapy is not recommended for patients with resected stage I or II disease. In patients with stage IIIA N2 disease, adjuvant radiation therapy is not recommended for routine use. However, a postoperative multimodality evaluation, including a consultation with a radiation oncologist, is recommended to assess benefits and risks of adjuvant radiation therapy for each patient with N2 disease.

    Purpose: To compare the outcome of familial versus sporadic prostate carcinoma after definitive external radiation. Methods and Materials: Between 1987 and 1996, 1214 men with clinically localized prostate cancer (T1-T4, N0/NX, M0) received definitive radiation therapy in our department. By retrospective review of charts and questioning of patients, a record on the presence or absence of prostate cancer in a first degree relative was obtained in 1164 men. Univariate and multivariate analysis was performed on these cases with relapse or rising prostate-specific antigen (PSA), local recurrence, metastasis, and survival as endpoints. Results: Familiar prostate cancer was present in 148 of 1164 men (13%). Men with familial disease were slightly but significantly younger (mean 66 years) at diagnosis than those with sporadic disease (mean 68 years) (p = 0.02). Apart from this there were no significant differences between the two groups in T-stage, Gleason score, pretreatment PSA levels, DNA ploidy, or serum testosterone levels. There were no significant differences in treatment parameters including radiation dose and the use of adjuvant androgen ablation. With a median follow-up of 42 months, there was no difference in freedom from relapse or rising PSA at 6 years between those with a family history (54%) and those without a family history (58%) (p = 0.171). Likewise there was no difference between the two groups when local recurrence or metastasis was the endpoint. Multiple subgroup analyses (younger and older; T1/T2 and T3; low Gleason and high Gleason; no androgen ablation and androgen ablation; race) failed to reveal any differences in outcome in any category between familial and sporadic disease. Among patients with a rising post-treatment PSA profile, PSA doubling times were similar in those with sporadic and familial disease. Conclusions: This study provides no evidence for any substantial difference between familial and sporadic prostate cancer either in

    Cancer pain is complex, and despite the introduction of the WHO cancer pain ladder, few studies have looked at the prevalence of adjuvant medication use in an inpatient palliative medicine unit. In this study, we evaluate the use of adjuvant pain medications in patients admitted to an inpatient palliative care unit and whether their use affects pain scores or opiate dosing. In this retrospective observational study, patients admitted to the inpatient palliative care unit over a 3-month period with a diagnosis of cancer on opioid therapy were selected. Data pertaining to demographics, diagnosis, oral morphine dose equivalent of the opioid at the time of discharge, adjuvant analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and pain scores as reported by nurses and physicians were collected. Seventy-seven patients were eligible over a 3-month period, out of which 65 (84 %) were taking an adjuvant medication. The most commonly prescribed adjuvant was gabapentin (70 %). Fifty-seven percent were taking more than one adjuvant. There were more women in the group receiving adjuvants (57 vs. 17%, p = 0.010). Those without adjuvants compared with those on adjuvants did not have worse pain scores on discharge as reported by physicians (0.8 ± 0.8 vs. 1.0 ± 0.7, p = 0.58) or nurses (2.0 ± 2.7 vs. 2.1 ± 2.6, p = 0.86). There was no difference in morphine equivalent doses of the opioid in both groups (median (min, max); 112 (58, 504) vs. 200 (30, 5,040)) at the time of discharge; 75-80 % of patients had improvement in pain scores as measured by a two-point reduction in numerical rating scale (NRS). This study shows that adjuvant medications are commonly used for treating pain in patients with cancer. More than half of study population were on two adjuvants or an adjuvant plus NSAID along with an opioid. We did not demonstrate any benefit in terms of improved pain scores or opioid doses with adjuvants, but this could reflect confounding variables and physician choice

    Pancreatic ductal adenocarcinoma represents a major oncological challenge. Despite improvements in surgical techniques, long-term survival after resection is poor, with few patients surviving after 5 years. Until recently, there have been no large randomized trials of adjuvant therapy in pancreatic ductal adenocarcinoma. However, major trials such as the European Study Group for Pancreatic Cancer (ESPAC-1) and ESPAC-3 trials have set new standards for patient recruitment and development in this field. Adjuvant therapy has the potential to improve both patient survival and quality of life after curative resection. Currently, the best treatment is with 5-fluorouracil with folinic acid, but in the light of ongoing clinical trials, this may be supplanted by gemcitabine as the treatment of choice. Chemoradiotherapy does not appear to be beneficial in the adjuvant setting, but trials of a wide variety of other techniques and agents in the treatment of advanced disease are being undertaken and some of these will almost certainly be extended into the adjuvant setting in time. Great progress has been made in the adjuvant treatment of pancreatic cancer in the past 10 years and similar advances are likely over the next decade.

The aim of this retrospective study was to investigate the general characteristics and survival of our patients receiving CRT. Material and Method: Between the years 2009-2013, 62 pancreatic cancer patients were taken into study who admitted to Van Training and Research Hospital. Eight patients who had whipple operation received radiotherapy (RT with concurrent CT. Fifty-four patients who were considered to be inoperable underwent CRT. As adjuvant treatment dose, 45 Gy (1,8 Gy/fx/day radiotherapy was administered to pancreas and regional lymph nodes. In patients who had taken definitive CRT, average 50.4 Gy (1.8 Gy/fx/day dose was given. Statistical analysis was carried out using SPSS 19 software package; Kaplan-Meier analysis method was used for survival and log-range test for comparisons. Results: Twenty-four patients (38.7% were female and 38 (61.3% were male. Eleven patients (17.7% were at stage IA, 16 (25.8% were stage IB, 13 (20.9% were stage IIA, 8 (12.9% were stage IIB and 14 (22.5% were staged as stage III. Two-year disease free survival (DFS; time from the date of biopsy until the date of recurrence was approximately 436 days and the median DFS was found to be 362 days. The average overall survival (OS time; time from the date of biopsy until the date of death were found to be approximately 854 days, the median survival time was found to be 916 days. Survival due to tumor localization (head, body and tail showed no significant difference statistically (log-range chi-square=0.366;p=0.833. Discussion: According to our single center experience, our data in pancreatic cancer patients were parallel with international data. In preclinical experiments, effective drug therapies for curative modalities are under investigation for pancreatic cancer patients.

    Adjuvant endocrine therapy compromises bone health in patients with breast cancer, causing osteopenia, osteoporosis, and fractures. Antiresorptive treatments such as bisphosphonates prevent and counteract these side-effects. In this trial, we aimed to investigate the effects of the anti-RANK ligand antibody denosumab in postmenopausal, aromatase inhibitor-treated patients with early-stage hormone receptor-positive breast cancer. In this prospective, double-blind, placebo-controlled, phase 3 trial, postmenopausal patients with early hormone receptor-positive breast cancer receiving treatment with aromatase inhibitors were randomly assigned in a 1:1 ratio to receive either denosumab 60 mg or placebo administered subcutaneously every 6 months in 58 trial centres in Austria and Sweden. Patients were assigned by an interactive voice response system. The randomisation schedule used a randomly permuted block design with block sizes 2 and 4, stratified by type of hospital regarding Hologic device for DXA scans, previous aromatase inhibitor use, and baseline bone mineral density. Patients, treating physicians, investigators, data managers, and all study personnel were masked to treatment allocation. The primary endpoint was time from randomisation to first clinical fracture, analysed by intention to treat. As an additional sensitivity analysis, we also analysed the primary endpoint on the per-protocol population. Patients were treated until the prespecified number of 247 first clinical fractures was reached. This trial is ongoing (patients are in follow-up) and is registered with the European Clinical Trials Database, number 2005-005275-15, and with ClinicalTrials.gov, number NCT00556374. Between Dec 18, 2006, and July 22, 2013, 3425 eligible patients were enrolled into the trial, of whom 3420 were randomly assigned to receive denosumab 60 mg (n=1711) or placebo (n=1709) subcutaneously every 6 months. Compared with the placebo group, patients in the denosumab group had a

    Ethnic and socioeconomic inequities in use of breast cancer adjuvant therapy are well documented in many countries including the USA, and are known to contribute to lower breast cancer survival among minority ethnic and socioeconomically deprived women. We investigated ethnic and socioeconomic inequities in use of adjuvant radiotherapy and chemotherapy in a cohort of women with invasive breast cancer in New Zealand. All women with newly diagnosed invasive breast cancer during 1999-2012 were identified from the Waikato Breast Cancer Register. Rates of chemotherapy use and radiotherapy use were assessed in women who were deemed to be eligible for chemotherapy (n = 1212) and radiotherapy (n = 1708) based on guidelines. Factors associated with use of chemotherapy and radiation therapy were analysed in univariate and multivariate regression models, adjusting for covariates. Overall, rates of chemotherapy and radiotherapy use were 69% (n = 836) and 87.3% (n = 1491), respectively. In the multivariate model, significantly lower rates of radiotherapy use were associated with Māori compared with NZ European (Odds Ratio [OR] = 0.63, 0.40-0.98), presence of comorbidity (OR = 0.49, 0.34-0.72), distance from hospital of over 100km (OR = 0.47, 0.23-0.96), mastectomy compared with breast conserving surgery (OR = 0.32, 0.17-0.56) and non-screen compared with screen detection (OR = 0.53, 0.35-0.79). No significant associations were observed between chemotherapy use and ethnic or socio-demographic factors. Improving access for radiotherapy, especially for women who are at a higher risk of not receiving optimum cancer therapy due to ethnicity, geography or socioeconomic status need to be recognized as a priority to reduce inequities in breast cancer care in New Zealand.

    Purpose: To evaluate actuarial rates of local failure in patients with pathologic N1 non–small-cell lung cancer and to identify clinical and pathologic factors associated with an increased risk of local failure after resection. Methods and Materials: All patients who underwent surgery for non–small-cell lung cancer with pathologically confirmed N1 disease at Duke University Medical Center from 1995–2008 were identified. Patients receiving any preoperative therapy or postoperative radiotherapy or with positive surgical margins were excluded. Local failure was defined as disease recurrence within the ipsilateral hilum, mediastinum, or bronchial stump/staple line. Actuarial rates of local failure were calculated with the Kaplan-Meier method. A Cox multivariate analysis was used to identify factors independently associated with a higher risk of local recurrence. Results: Among 1,559 patients who underwent surgery during the time interval, 198 met the inclusion criteria. Of these patients, 50 (25%) received adjuvant chemotherapy. Actuarial (5-year) rates of local failure, distant failure, and overall survival were 40%, 55%, and 33%, respectively. On multivariate analysis, factors associated with an increased risk of local failure included a video-assisted thoracoscopic surgery approach (hazard ratio [HR], 2.5; p = 0.01), visceral pleural invasion (HR, 2.1; p = 0.04), and increasing number of positive N1 lymph nodes (HR, 1.3 per involved lymph node; p = 0.02). Chemotherapy was associated with a trend toward decreased risk of local failure that was not statistically significant (HR, 0.61; p = 0.2). Conclusions: Actuarial rates of local failure in pN1 disease are high. Further investigation of conformal postoperative radiotherapy may be warranted.

    Breast cancer survivors have a higher cardiovascular morbidity/mortality rate, when compared with healthy age-matched general population. Electrocardiography (ECG) changes have been found to be associated with chemo- and radiation therapy. In the present study we investigated changes in ECG patterns following modern adjuvant therapy for breast cancer. A standard 12-lead electrocardiogram was recorded at rest three times (prior and after adjuvant therapy) and retrospectively analyzed in 414 breast cancer patients, who participated in the open prospective phase III randomized trial (BREX) of exercise training 2005-2007. New electrocardiographic changes in the T-wave or ST-segment (depression or elevation) after the adjuvant therapy were recorded in 49 patients (13%). In multivariate analyses, hypertension treated with anti-hypertensive medication was the only significant factor associated with irreversible ECG changes (OR=4.71; 95% CI=1.36-16.38; p=0.015). New irreversible pathological electrocardiographic changes, which acquired during the adjuvant therapy, had a clear relationship with hypertension This patients subgroup needs to be studied further.

    The mature results of the neoadjuvant and adjuvant chemotherapy arms of the nonrandomized, phase 2 Yale University cisplatin, bleomycin, methotrexate, and 5-FU protocol are presented. Sixty-seven patients were prospectively accrued with a median follow-up of 5.4 years, and standard parameters of toxicity and efficacy were studied. Both univariate and multivariate analyses were applied. The 5-year disease-free survival of 78% for the 25 patients in the adjuvant group, of which 80% had high-risk features including positive margins, parametria, and lymph nodes and 28% had adenocarcinomas, was comparable to recent relevant literature. Only 64% of patients in this group received consolidation radiation therapy, which did not impact on survival. Only 12% of patients recurred distantly. Notably, those who received 4 months or more of chemotherapy had prolonged survival (P = 0.012). In the neoadjuvant group, chemotherapy response rate among 42 patients (with stages 1B-IIIB cancer) was 79% (50% partial response, 29% complete response), and no patient progressed. In the subgroup of 22 patients who underwent surgery after chemotherapy, 59% had nonsquamous histology. Forty-five percent of patients with stage IIB cancer were deemed operable after chemotherapy. Ninety-five percent received postoperative radiation therapy. There was a 9% pathologic complete response rate, with positive lymph nodes found in 27%. Notably, those who received 3 months or less of chemotherapy had improved overall survival (P = 0.030). Survival rates of these 22 patients at 3 and 5 years were 73% and 63%, respectively. Although not randomized, these survival rates were similar to those achieved with chemoradiation. Although there are several logistical/design features of the cisplatin, bleomycin, methotrexate, and 5-FU regimen that are not in line with the current chemotherapy era, our experience with this well-tolerated regimen can serve as a proof of principle. Our data suggests that both neoadjuvant

    Current adjuvant treatment modalities for breast cancer that express the estrogen receptor or progesterone receptor include adjuvant anti-estrogen therapies, and tamoxifen and aromatase inhibitors. Bone, including the jaw, is an endocrine-sensitive organ, as are other oral structures. This review examines the potential links between adjuvant anti-estrogen treatments in postmenopausal women with hormone receptor positive breast cancer and oral health. A search of PubMed, EMBASE, CENTRAL, and the Web of Knowledge was conducted using combinations of key terms “breast,” “cancer,” “neoplasm,” “Tamoxifen,” “Aromatase Inhibitor,” “chemotherapy,” “hormone therapy,” “alveolar bone loss,” “postmenopausal bone loss,” “estrogen,” “SERM,” “hormone replacement therapy,” and “quality of life.” We selected articles published in peer-reviewed journals in the English. The authors found no studies reporting on periodontal diseases, alveolar bone loss, oral health, or oral health-related quality of life in association with anti-estrogen breast cancer treatments in postmenopausal women. Periodontal diseases, alveolar bone density, tooth loss, and conditions of the soft tissues of the mouth have all been associated with menopausal status supporting the hypothesis that the soft tissues and bone of the oral cavity could be negatively affected by anti-estrogen therapy. As a conclusion, the impact of adjuvant endocrine breast cancer therapy on the oral health of postmenopausal women is undefined. The structures of the oral cavity are influenced by estrogen; therefore, anti-estrogen therapies may carry the risk of oral toxicities. Oral health care for breast cancer patients is an important but understudied aspect of cancer survivorship. PMID:22986813

    One of the most widely used and potent immunological adjuvants is a mixture of soluble triterpene glycosides purified from the soap bark tree (Quillaja saponaria). Despite challenges in production, quality control, stability and toxicity, the QS-21 fraction from this extract has exhibited exceptional adjuvant properties for a range of antigens. It possesses an ability to augment clinically significant antibody and T-cell responses to vaccine antigens against a variety of infectious diseases, degenerative disorders and cancers. The recent synthesis of active molecules of QS-21 has provided a robust method to produce this leading vaccine adjuvant in high purity as well as to produce novel synthetic QS-21 congeners designed to induce increased immune responsiveness and decreased toxicity.

    Randomized trials have established the effectiveness of 5-fluorouracil-based adjuvant chemotherapy for stage III resectable colon cancer but the toxicity has not been well established outside the trial setting. The objective of this study was to estimate the risk of various toxicity-related endpoints among the elderly patients. Patients diagnosed with stage III colon cancer in 1991 to 2005 were identified from the Surveillance, Epidemiology, and End Results-Medicare database. Chemotherapy use within 3 months after tumor resection was identified from submitted claims. We reported the 3-month cumulative incidence rate (CIR) for gastrointestinal and hematologic toxicities. The risk of ischemic heart disease in relation to chemotherapy use and length was assessed using Cox regression models, stratified by age and comorbidity subgroups. Of the 12,099 patients, 63.9% (n=7740) received adjuvant chemotherapy. Common gastrointestinal and hematologic toxicities among chemotherapy group include volume depletion disorder (CIR=9.1%), agranulocytosis (CIR=3.4%), diarrhea (CIR=2.4%), nausea and vomiting (CIR=2.3%). Chemotherapy use was significantly associated with the onset of these toxicities [hazard ratio (HR)=2.76; 95% confidence interval (95% CI)=2.42-3.15]. The risk of ischemic heart disease was slightly associated with chemotherapy use (HR=1.08, 95% CI=0.96-1.22), but significant only among patients aged colon cancer. On account of the effects of these side effects on treatment discontinuation, rehospitalization, and overall health status, some close monitoring and preventive measures may be emphasized to maximize the benefits of adjuvant chemotherapy.

    Saponins comprise a class of plant natural products that incorporate a lipophilic terpenoid core, to which is appended one or more carbohydrate residues. They are amphiphilic molecules and often exhibit toxic biological profiles, likely as a result of their roles as vital components in protective coatings to defend against phytopathogen infection and insect predation. The most notable of adjuvant-active saponins investigated for vaccine development come from the Chilean Soapbark Tree, Quillaja saponaria (i.e., QS). More than 30 years ago, semi-purified extracts (i.e., Quil A) from the cortex of Quillaja saponaria were found to be highly effective as adjuvants in veterinary vaccines. However, due to significant and variable toxicity effects, Quil A was not deemed appropriate for human vaccines. More refined purification methods have led to multiple fractions which are derived from the original plant extract. As such, QS-21 to date appears to be one of the more scientifically interesting and robust adjuvants in use in vaccinology. The role of QS-21 as an adjuvant for use in a variety of cancer vaccine trials and its comparison to other adjuvants is discussed in this review. PMID:25473385

    Up to now, the role of adjuvant radiation therapy and the extent of lymph node dissection for early stage endometrial cancer are controversial. In order to clarify the current position of the given adjuvant treatment options, a systematic review was performed. Both, Pubmed and ISI Web of Knowledge database were searched using the following keywords and MESH headings: 'Endometrial cancer', 'Endometrial Neoplasms', 'Endometrial Neoplasms/radiotherapy', 'External beam radiation therapy', 'Brachytherapy' and adequate combinations. Recent data from randomized trials indicate that external beam radiation therapy - particularly in combination with extended lymph node dissection - or radical lymph node dissection increases toxicity without any improvement of overall survival rates. Thus, reduced surgical aggressiveness and limitation of radiotherapy to vaginal-vault-brachytherapy only is sufficient for most cases of early stage endometrial cancer

    Full Text Available Background: The adjuvant short course 9-week trastuzumab combination therapy for human epidermal receptor 2 positive breast cancer patients may often be considered as a cost-effective and safe option and has important implications for the Indian subcontinent as well as other developing countries. However, such regimens of shorter duration trastuzumab therapy like FinHer, offered in view of economic constraints, may not be able to achieve globally comparable cure rates in early breast cancer especially with high-risk women with more than 3 lymph node positive. Methods and Material: Outcome of 21 patients with HER2 positive breast cancer was treated with short course trastuzumab combination chemotherapy in the adjuvant setting was studied. Results: Out of 21 patients 15 are alive and disease free with a follow up of up to 73 months (median follow up 42 months.

    Early hormone-receptor-positive breast cancer is a chronic relapsing disease that can remain clinically silent for many years. The NCIC-CTG MA.17/BIG 1-97 trial randomized disease-free early breast cancer patients who had received five years of adjuvant tamoxifen to either letrozole or placebo and was the first to demonstrate a benefit with extended endocrine therapy. MA.17/BIG 1-97 was stopped at the first interim analysis because disease free survival was strongly prolonged in the letrozole arm. Subsequent subset analyses and longer follow up have shown that this therapy improved survival across all groups, particularly among women with node-positive disease and those that were pre-menopausal at time of study enrolment. The MA.17/BIG 1-97 study should be considered a paradigm for extended adjuvant endocrine therapy in hormone-receptor-positive early breast cancer. Copyright © 2012 Elsevier Ireland Ltd.

    Lung disease associated with FOLFOX (oxaliplatin/5-fluorouracil/leucovorin) chemotherapy is uncommon. We describe a case of cryptogenic organizing pneumonia (COP) occurring in a 78-year-old woman after receiving 2 cycles of modified FOLFOX6 as adjuvant chemotherapy for treatment of resected nonmetastatic colon cancer. This patient presented with respiratory symptoms including cough with scant clear sputum and wheezing on day 10 of the second cycle of mFOLFOX6. Despite therapy with systemic antibiotics and supplemental oxygen, she had a steady and relentless progression of her respiratory symptoms and status, with chest radiographs revealing progressive bilateral pulmonary infiltrates. Further chest radiograph evaluation demonstrated findings consistent with COP. Antibiotics were discontinued and methylprednisolone sodium succinate initiated as the mainstay of management for COP. The patient required a higher dose of methylprednisolone sodium succinate than typical for initial response with doses up to 3 mg/kg per d leading to prompt improvement in her respiratory symptoms and function and declining need for supplemental oxygen therapy. Chest radiographs also showed improvement. The Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 5) between the patient's COP and the FOLFOX chemotherapy. Clinicians should be aware of the potential for this uncommon, yet severe adverse reaction associated with the FOLFOX chemotherapy.

    To evaluate the incidences and potential predictive factors for symptomatic radiation pneumonitis (SRP) and radiographic pulmonary toxicity (RPT) following adjuvant radiotherapy (RT) for patients with breast cancer. A particular focus was made to correlate RPT with the dose volume histogram (DVH) parameters based on three-dimensional RT planning (3D-RTP) data. From September 2003 through February 2006, 171 patients with breast cancer were treated with adjuvant RT following breast surgery. A radiation dose of 50.4 Gy was delivered with tangential photon fields on the whole breast or chest wall. A single anterior oblique photon field for supraclavicular (SCL) nodes was added if indicated. Serial follow-up chest radiographs were reviewed by a chest radiologist. Radiation Therapy Oncology Group (RTOG) toxicity criteria were used for grading SRP and a modified World Health Organization (WHO) grading system was used to evaluate RPT. The overall percentage of the ipsilateral lung volume that received {>=} 15 Gy (V{sub 15}), 20 Gy (V{sub 20}), and 30 Gy (V{sub 30}) and the mean lung dose (MLD) were calculated. We divided the ipsilateral lung into two territories, and defined separate DVH parameters, i.e., V{sub 15} {sub TNGT}, V{sub 20} {sub TNGT}, V{sub 30} {sub TNGT}, MLD {sub TNGT}, and V{sub 15} {sub SCL}, V{sub 20} {sub SCL} V {sub 30SCL}, MLD {sub SCL} to assess the relationship between these parameters and RPT. Four patients (2.1%) developed SRP (three with grade 3 and one with grade 2, respectively). There was no significant association of SRP with clinical parameters such as, age, pre-existing lung disease, smoking, chemotherapy, hormonal therapy and regional RT. When 137 patients treated with 3D-RTP were evaluated, 13.9% developed RPT in the tangent (TNGT) territory and 49.2% of 59 patients with regional RT developed RPT in the SCL territory. Regional RT ({rho} < 0.001) and age ({rho} = 0.039) was significantly correlated with RPT. All DVH parameters except for V

  3. Advantages of adjuvant chemotherapy for patients with triple-negative breast cancer at Stage II: usefulness of prognostic markers E-cadherin and Ki67

    Science.gov (United States)

    2011-01-01

    Introduction Triple-negative breast cancer (TNBC), which is characterized by negativity for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 (HER2), is a high risk breast cancer that lacks specific targets for treatment selection. Chemotherapy is, therefore, the primary systemic modality used in the treatment of this disease, but reliable parameters to predict the chemosensitivity of TNBC have not been clinically available. Methods A total of 190 TNBC patients who had undergone a curative resection of a primary breast cancer were enrolled. The adjuvant chemotherapy was performed for 138 (73%) of 190 TNBC cases; 60 cases had an anthracyclin-based regimen and 78 a 5-fluorouracil-based regimen. The prognostic value of E-cadherin, Ki67 and p53 expression in the outcome of TNBC patients with adjuvant chemotherapy was evaluated by immunohistochemistry. Results The adjuvant therapy group, especially those with Stage II TNBC, had a more favorable prognosis than the surgery only group (P = 0.0043), while there was no significant difference in prognosis between the anthracyclin-based regimen and 5-fluorouracil-based regimen. Patients with E-cadherin-negative and Ki67-positive expression showed significantly worse overall survival time than those with either E-cadherin-positive or Ki67-negative expression (P Ki67-positive expression was strongly predictive of poor overall survival (P = 0.004) in TNBC patients receiving adjuvant chemotherapy. In contrast, p53 status was not a specific prognostic factor. Conclusions Adjuvant therapy is beneficial for Stage II TNBC patients. The combination of E-cadherin and Ki67 status might be a useful prognostic marker indicating the need for adjuvant chemotherapy in Stage II TNBC patients. PMID:22126395

    Preoperative chemoradiotherapy followed by total mesorectal excision (TME) is the standard treatment for stage III lower rectal cancer worldwide. However, in Japan, the standard treatment is TME with lateral pelvic lymph node dissection (LPLD) followed by adjuvant chemotherapy. We examined the safety and efficacy of adjuvant therapy with oxaliplatin, leucovorin, and 5-fluorouracil (modified FOLFOX6) after TME with LPLD. This retrospective study included 33 patients who received modified FOLFOX6 after TME with LPLD for stage III lower rectal cancer. The overall completion rate of 12 cycles of adjuvant modified FOLFOX6 was 76%. Grade 3 or 4 neutropenia was observed in eight patients (24%). Sensory neuropathy was observed in 32 patients (97%) with 4 (12%) having a grade 3 event. The disease-free survival (DFS) rate was 45% at 3 years. Adjuvant modified FOLFOX6 was feasible in patients with stage III lower rectal cancer after TME with LPLD. Copyright© 2015 International Institute of Anticancer Research (Dr. John G.

    Adjuvant chemotherapy is a crucial part of treatment for patients with locally advanced colon cancer. This study was conducted to investigate the actual practice in the use of adjuvant chemotherapy for patients with high-risk stage II or stage III colon cancer in South Korea. This was a 24-month open-label, prospective, observational study conducted at 12 centers across South Korea. Patients with high-risk stage II and stage III colon cancer receiving adjuvant chemotherapy after curative surgery were included, and data were collected at baseline, third, and sixth month. A total of 246 patients were included in the analyses. Of five available regimens (FOLFOX, CAPOX, 5-FU/LV, capecitabine, and UFT/LV), FOLFOX was most commonly used (82.5%). Investigators indicated the "efficacy" as the major cause for selecting FOLFOX or CAPOX. For 5-FU/LV, capecitabine, or UFT/LV, the "safety" or "patient's characteristics (age, comorbidity, and stage)" was one of the most important selecting factors. Patients receiving 5-FU/LV, capecitabine, or UFT/LV had older age, worse PS and lower disease stage (stage II) than patients receiving FOLFOX or CAPOX. Hematologic toxicities were the most common cause of dose adjustment and treatment delay. In South Korea, FOLFOX was the most commonly used regimen for adjuvant chemotherapy and its efficacy was the main cause for selecting this regimen. Patients receiving 5-FU/LV, capecitabine, or UFT/LV had older age, worse PS and lower disease stage (stage II) than patients receiving FOLFOX or CAPOX.

    In Thailand, there has been no economic evaluation study of adjuvant chemotherapy for stage III colon cancer patients after resection. This study aims to evaluate the cost-utility of all chemotherapy regimens currently used in Thailand compared with the adjuvant 5-fluorouracil/leucovorin (5-FU/LV) plus capecitabine as the first-line therapy for metastatic disease in patients with stage III colon cancer after resection. A cost-utility analysis was performed to estimate the relevant lifetime costs and health outcomes of chemotherapy regimens based on a societal perspective using a Markov model. The results suggested that the adjuvant 5-FU/LV plus capecitabine as the first-line therapy for metastatic disease would be the most cost-effective chemotherapy. The adjuvant FOLFOX and FOLFIRI as the first-line treatment for metastatic disease would be cost-effective with an incremental cost-effectiveness ratio of 299,365 Thai baht per QALY gained based on a societal perspective if both prices of FOLFOX and FOLFIRI were decreased by 40%.

    Purpose: To investigate the outcomes of adjuvant chemotherapy (CT) or chemoradiotherapy (CRT) after simultaneous surgical resection in rectal cancer patients with liver metastases (LM). Materials and Methods: One hundred and eight patients receiving total mesorectal excision for rectal cancer and surgical resection for LM were reviewed. Forty-eight patients received adjuvant CRT, and 60 were administered CT alone. Recurrence patterns and prognosis were analyzed. Disease-free survival (DFS) and overall survival (OS) rates were compared between the CRT and CT groups. The inverse probability of the treatment-weighted (IPTW) method based on the propensity score was used to adjust for selection bias between the two groups. Results: At a median follow-up period of 47.7 months, 77 (71.3%) patients had developed recurrences. The majority of recurrences (68.8%) occurred in distant organs. By contrast, the local recurrence rate was only 4.7%. Median DFS and OS were not significantly different between the CRT and CT groups. After applying the IPTW method, we observed no significant differences in terms of DFS (hazard ratio [HR], 1.347; 95% confidence interval [CI], 0.759-2.392; p = 0.309) and OS (HR, 1.413; CI, 0.752-2.653; p = 0.282). Multivariate analyses showed that unilobar distribution of LM and normal preoperative carcinoembryonic antigen level (<6 mg/mL) were significantly associated with longer DFS and OS. Conclusions: The local recurrence rate after simultaneous resection of rectal cancer with LM was relatively low. DFS and OS rates were not different between the adjuvant CRT and CT groups. Adjuvant CRT may have a limited role in this setting. Further prospective randomized studies are required to evaluate optimal adjuvant treatment in these patients.

    Purpose: Adjuvant and salvage irradiation have been shown to improve local control after radical prostatectomy for prostatic cancer in patients with high risk pathologic features, rising PSA, or evidence of local failure. Transient androgen deprivation combined with primary irradiation has resulted in improved local control and biochemical disease free survival in patients with locally advanced, unresected, prostate cancer. This retrospective study evaluates whether transient androgen blockade improves the outcome from post-prostatectomy irradiation given as either adjuvant or salvage therapy. Methods: From August, 1985 to December, 1995, 105 patients were treated with radiotherapy to the prostatic fossa following radical prostatectomy for adenocarcinoma of the prostate. No patient had clinically or radiographically evident distant disease. Median follow-up was 4.6 years from the date of surgery and 3.2 years from completion of radiotherapy. Findings at prostatectomy included capsular penetration in 38 patients, seminal vesicle involvement in 42 patients, lymph node involvement in 15 patients, and positive surgical margins in 70 patients. Treatment was administered as adjuvant therapy for high risk pathologic features in 39 patients, for persistent or rising PSA in 52 patients, or for clinically evident local recurrence in 14 patients. Of the 105 patients, 32 received combined androgen deprivation/radiotherapy and 73 received radiotherapy alone. Both groups received 60-70 Gy in 2 Gy daily fractions to the prostatic fossa. Selected patients with poor prognostic features received pelvic irradiation to a median dose of 50 Gy. Androgen deprivation typically consisted of Lupron and Flutamide for 4 to 6 months before, during, and in selected cases, after irradiation. No patients received maintenance androgen deprivation or underwent orchiectomy. Tumor stage, lymph node status, Gleason sum, and indications for treatment did not differ significantly between the two groups

    Purpose: To assess the potential advantage of intensity-modulated radiotherapy (IMRT) over conformal planning for postoperative adjuvant radiotherapy in patients with gastric carcinoma. Methods and Materials: Twenty patients who had undergone treatment planning with conformal beam arrangements for 4500 cGy adjuvant radiotherapy between 2000 and 2001 underwent repeat planning using IMRT techniques. Conformal five-field plans were compared with seven- to nine-field coplanar sliding-window IMRT plans. For each patient, the cumulative dose-volume histograms and organ-dose summaries (without distributions or digitally reconstructed radiographs) were provided to two independent, 'blinded' GI radiation oncologists. The oncologists indicated which plan provided better planning target volume coverage and critical organ sparing, any safety concerns with either plan, and which plan they would choose to treat the patient. Results: In 18 (90%) of 20 cases, both oncologists chose the same plan. Cases with disagreement were given to a third 'blinded' reviewer. A 'preferred plan' could be determined in 19 (95%) of 20 cases. IMRT was preferred in 17 (89%) of 19 cases. In 4 (20%) of 20 IMRT plans at least one radiation oncologist had safety concerns because of the spinal cord dose (3 cases) or small bowel dose (2 cases). Of 42 ratings, IMRT was thought to provide better planning target volume coverage in 36 (86%) and better sparing of the spinal cord in 31 (74%) of 42, kidneys in 29 (69%), liver in 30 (71%), and heart in 29 (69%) of 42 ratings. The median underdose volume (1.7 vs. 4.1 cm 3 ), maximal dose to the spinal cord (36.85 vs. 45.65 Gy), and dose to 50% of the liver (17.29 vs. 27.97), heart (12.89 vs. 15.50 Gy), and left kidney (15.50 vs. 16.06 Gy) were lower with IMRT than with the conformal plans. Conclusion: Compared with the conformal plans, oncologists frequently preferred IMRT plans when using dose-volume histogram data. The advantages of IMRT plans include both

    There has been an increasing interest in the role of tumour location in the treatment and prognosis of patients with colorectal cancer (CRC), specifically in the adjuvant setting. Together with genomic data, this has led to the proposal that right-sided and left-sided tumours should be considered as distinct biological and clinical entities. The aim of the present study was to examine the relationship between tumour location, tumour microenvironment, systemic inflammatory response (SIR), adjuvant chemotherapy and survival in patients undergoing potentially curative surgery for stage I-III colon and rectal cancer. Clinicopathological characteristics were extracted from a prospective database. MMR and BRAF status was determined using immunohistochemistry. The tumour microenvironment was assessed using routine H&E pathological sections. SIR was assessed using modified Glasgow Prognostic Score (mGPS), neutrophil:lymphocyte ratio (NLR), neutrophil:platelet score (NPS) and lymphocyte:monocyte ratio (LMR). Overall, 972 patients were included. The majority were over 65 years (68%), male (55%), TNM stage II/III (82%). In all, 40% of patients had right-sided tumours and 31% had rectal cancers. Right-sided tumour location was associated with older age (P=0.001), deficient MMR (P=0.005), higher T stage (Plocation was consistently associated with a high SIR, mGPS (Plocation, adjuvant chemotherapy (P=0.632) or cancer-specific survival (CSS; P=0.377). In those 275 patients who received adjuvant chemotherapy, right-sided location was not associated with the MMR status (P=0.509) but was associated with higher T stage (P=0.001), venous invasion (P=0.036), CD3 + at the invasive margin (P=0.033) and CD3 + within cancer nests (P=0.012). There was no relationship between tumour location, SIR or CSS in the adjuvant group. Right-sided tumour location was associated with an elevated tumour lymphocytic infiltrate and an elevated SIR. There was no association between tumour location and

    For the past several decades, cancer patients in the U.S. have chosen the use of natural products as an alternative or complimentary medicine approach to treat or improve their quality of life via reduction or prevention of the side effects during or after cancer treatment. The genus Ganoderma includes about 80 species of mushrooms, of which several have been used for centuries in traditional Asian medicine for their medicinal properties, including anticancer and immunoregulatory effects. Numerous bioactive compounds seem to be responsible for their healing effects. Among the approximately 400 compounds produced by Ganoderma spp., triterpenes, peptidoglycans and polysaccharides are the major physiologically-active constituents. Ganoderma anticancer effects are attributed to its efficacy in reducing cancer cell survival and growth, as well as by its chemosensitizing role. In vitro and in vivo studies have been conducted in various cancer cells and animal models; however, in this review, we focus on Ganoderma’s efficacy on breast cancers. Evidence shows that some species of Ganoderma have great potential as a natural therapeutic for breast cancer. Nevertheless, further studies are needed to investigate their potential in the clinical setting and to translate our basic scientific findings into therapeutic interventions for cancer patients.

    Two identical randomized controlled trials designed to optimize adjuvant treatment of colon cancer (CC) (n =855) and rectal cancer (RC) (n = 796) were performed. Long-term evaluation confirmed that the addition of folinic acid (FA) to 5-fluorouracil (5-FU) improved 7-year overall survival (OS) in CC but not in RC and revealed different patterns of recurrence in patients with CC and those with RC. Our aim was to compare long-term results of adjuvant treatment of colon cancer (CC) and rectal cancer (RC). Adjuvant chemotherapy of CC improved overall survival (OS), whereas that of RC remained at the level achieved by 5-fluorouracil (5-FU). We separately conducted 2 identically designed adjuvant trials in CC and RC. Patients were assigned to adjuvant chemotherapy with 5-FU alone, 5-FU + folinic acid (FA), or 5-FU + interferon-alfa. The first study enrolled patients with stage IIb/III CC, and the second study enrolled patients with stage II/III RC. All patients with RC received postoperative irradiation. Median follow-up for all patients with CC (n = 855) and RC (n = 796) was 4.9 years. The pattern and frequency of recurrence differed significantly, especially lung metastases, which occurred more frequently in RC (12.7%) than in CC (7.3%; P < .001). Seven-year OS rates for 5-FU, 5-FU + FA, and 5-FU + IFN-alfa were 54.1% (95% confidence interval [CI], 46.5-61.0), 66.8% (95% CI, 59.4-73.1), and 56.7% (95% CI, 49.3-63.4) in CC and 50.6% (95% CI, 43.0-57.7), 56.3% (95% CI, 49.4-62.7), and 54.8% (95% CI, 46.7-62.2) in RC, respectively. A subgroup analysis pointed to a reduced local recurrence (LR) rate and an increased OS by the addition of FA in stage II RC (n = 271) but not in stage III RC (n = 525). FA increased 7-year OS by 12.7 percentage points in CC but was not effective in RC. Based on these results and the pattern of metastases, our results suggest that the chemosensitivity of CC and RC may be different. Strategies different from those used in CC may be successful to

    2017-06-01

    Full Text Available Thymoquinone (TQ, the main bioactive component of Nigella sativa, has been found to exhibit anticancer effects in numerous preclinical studies. Due to its multitargeting nature, TQ interferes in a wide range of tumorigenic processes and counteracts carcinogenesis, malignant growth, invasion, migration, and angiogenesis. Moreover, TQ can specifically sensitize tumor cells toward conventional cancer treatments (e.g., radiotherapy, chemotherapy, and immunotherapy and simultaneously minimize therapy-associated toxic effects in normal cells. In this review, we summarized the adjuvant potential of TQ as observed in various in vitro and in vivo animal models and discussed the pharmacological properties of TQ to rationalize its supplementary role in potentiating the efficacy of standard therapeutic modalities namely surgery, radiotherapy, chemotherapy, and immunotherapy. Altogether, we suggest further comprehensive evaluation of TQ in preclinical and clinical levels to delineate its implied utility as a novel complementary adjuvant therapy for cancer treatment.

    Multidisciplinary team (MDT) meetings are used to optimise expert decision-making about treatment options, but such expertise is not digitally transferable between centres. To help standardise medical decision-making, we developed a machine learning model designed to predict MDT decisions about adjuvant breast cancer treatments. We analysed MDT decisions regarding adjuvant systemic therapy for 1065 breast cancer cases over eight years. Machine learning classifiers with and without bootstrap aggregation were correlated with MDT decisions (recommended, not recommended, or discussable) regarding adjuvant cytotoxic, endocrine and biologic/targeted therapies, then tested for predictability using stratified ten-fold cross-validations. The predictions so derived were duly compared with those based on published (ESMO and NCCN) cancer guidelines. Machine learning more accurately predicted adjuvant chemotherapy MDT decisions than did simple application of guidelines. No differences were found between MDT- vs. ESMO/NCCN- based decisions to prescribe either adjuvant endocrine (97%, p = 0.44/0.74) or biologic/targeted therapies (98%, p = 0.82/0.59). In contrast, significant discrepancies were evident between MDT- and guideline-based decisions to prescribe chemotherapy (87%, p machine learning models. A machine learning approach based on clinicopathologic characteristics can predict MDT decisions about adjuvant breast cancer drug therapies. The discrepancy between MDT- and guideline-based decisions regarding adjuvant chemotherapy implies that certain non-clincopathologic criteria, such as patient preference and resource availability, are factored into clinical decision-making by local experts but not captured by guidelines.

    It remains controversial whether patients with Stage II colorectal cancer would benefit from adjuvant chemotherapy after radical resection. The aim of this study was to establish two mathematical models to identify the suitable patients for adjuvant chemotherapy. The current study comprised of two steps. In the first step, 353 patients with Stage II colorectal cancer who underwent surgical procedures at the Third Affiliated Hospital of Sun Yat-sen University between June 2006 and December 2015 were entered and followed up for 6-120 months. Their clinical data were collected and enrolled into the database. We established two mathematical models by univariate and multivariate Cox regression analysis to identify the target patients; in the second step, 230 patients under the same standard between January 2012 and December 2016 were entered and followed up for 3-62 months to verify the two models' validation. In the first step, totally 340 surgical patients with Stage II colorectal cancer were finally enrolled in this study. Statistical analysis showed that tumor differentiation (TD) (P models: (1) OS risk score = 1.116 × TD + 2.202 × LVI + 3.676 × UPM + 1.438 × LN - 0.493; (2) DFS risk score = 0.789 × TD + 2.074 × LVI + 3.183 × UPM + 1.329 × LN - 0.432. According to the models and cutoff points [(0.07, 1.33) and (-0.04, 1.30), respectively], patients can be divided into three groups: low-risk, moderate-risk, and high-risk. Moreover, the high-risk group patients could benefit from adjuvant chemotherapy. In the second step, totally 221 patients were finally used to verify the models' validation. The results proved that the models were accurate and feasible (Ppredictive models, patients with Stage II colorectal cancer in the high-risk group are strongly recommended for adjuvant chemotherapy, thus facilitating the individualized and precise treatment.

    Abstract Background A complete pathological response to neo-adjuvant chemo-radiation for oesophageal cancer is associated with favourable survival. However, such a benefit is seen in the minority. If one could identify, at diagnosis, those patients who were unlikely to respond unnecessary toxicity could be avoided and alternative treatment can be considered. The aim of this review was to highlight predictive markers currently assessed and evaluate their clinical utility. Methods A systematic ...

    Full Text Available Introduction. Breast cancer is the most frequent malignant disease in women with about 25% compared to all malignant tumours. Chemotherapy, antiestrogen and ovarian ablation/ supression present effective adjuvant approach for premenopausal women diagnosed with hormonal depended, operable breast cancer. Objective. To evaluate benefits of combined chemo/hormonal therapy that is undutiful, but optimal application has not yet been clearly determined. Methods. Thirty-six women were divided into three therapy groups. The first group (13 women was treated with six cycles of adjuvant FAC chemotherapy followed by regular check-ups; the second group (13 women after six cycles of adjuvant FAC chemotherapy continued treatment with a two-year application of goserelin given by subcutaneous injections (FAC-Z; the third group (10 women, after six cycles of adjuvant FAC chemotherapy continued with once per month application of gorselin for two years and a daily application of 20 mg tamoxifen for five years (FAC-Z-T. The length of overall disease free period and survival were analyzed in all three groups. Results. The benefit of LH-RH analogues in premenopausal women with hormone-dependent breast cancer was found to be low, and probably limited to smaller subgroups of patients, possibly such as those with either both steroid receptors positive (ER and PR or those with an extremely high level of steroid receptors. In our paper, analyses of such subgroups could not been performed due to a small sample of patients. The effect of therapy is better in patients, who developed amenorrhoea, regardless of the type of later hormonal therapy. Conclusion. Ovarial ablation, whatever the method, should be probably applied as early as possible within the treatment of early breast cancer, especially in patients in whom chemotherapy induced amenorrhoea is not expected, i.e. in very young female patients.

    Coexistence of breast cancer and tuberculosis is rare. In most cases, involvement by tuberculosis occurs in axillary lymph nodes. We report a case of a 43-years-old patient who had undergone adenomastectomy and left sentinel lymph node biopsy due to a triple negative ductal carcinoma. At the end of adjuvant treatment, the patient had an atypical lymph node in the left axilla. Lymph node was excised, and after laboratory analysis, the diagnosis was ganglion tuberculosis.

    Purpose Several factors contribute to the pervasive Black-White disparity in breast cancer mortality in the U.S., such as tumor biology, access to care and treatments received including adjuvant hormonal therapy (AHT), which significantly improves survival for hormone-receptor positive breast cancers (HR+). We analyzed South Carolina Central Cancer Registry-Medicaid linked data to determine if, in an equal access health care system, racial differences in the receipt of AHT exist. Methods We evaluated 494 study-eligible, Black (n=255) and White women (n=269) who were under 65 years old and diagnosed with stages I–III, HR+ breast cancers between 2004 and 2007. Bivariate and multivariate analyses were conducted to assess receipt of ≥ 1 AHT prescriptions at any point in time following (ever-use) or within 12 months of (early-use) breast cancer diagnosis. Results Seventy-two percent of the participants were ever-users (70% Black, 74% White) and 68% were early-users (65% Black, 71% White) of AHT. Neither ever-use (adjusted OR (AOR)=0.75, 95% CI: 0.48–1.17) nor early-use (AOR=0.70, 95% CI: 0.46–1.06) of AHT differed by race. However, receipt of other breast cancer-specific treatments was independently associated with ever-use and early-use of AHT [ever-use: receipt of surgery (AOR= 2.15, 95% CI: 1.35–3.44); chemotherapy (AOR=1.97, 95% CI: 1.22–3.20); radiation (AOR=2.33, 95% CI: 1.50–3.63); early-use: receipt of surgery (AOR=2.03, 95% CI: 1.30–3.17); chemotherapy (AOR=1.90, 95% CI: 1.20–3.03); radiation (AOR=1.73, 95% CI: 1.14–2.63)]. Conclusions No racial variations in use of AHT among women with HR+ breast cancers insured by Medicaid in South Carolina were identified, but overall rates of AHT use by these women is low. Strategies to improve overall use of AHT should include targeting breast cancer patients who do not receive adjuvant chemotherapy and/or radiation. PMID:27120468

    Propolis is a bee-metabolized resinous substance (bee glue) from plant sap and gums. It has been in usage as a healing agent since antiquity, yet has not garnered global popularity as a health promoter. Its biological effects, which range from antimicrobial, antioxidant, anti-inflammatory, antidiabetic, dermatoprotective, anti-allergic, laxative and immunomodulatory to anticancer, have been validated. Propolis has shown efficacy against brain, head and neck, skin, breast, liver, pancreas, kidney, bladder, prostate, colon and blood cancers. The inhibition of matrix metalloproteinases, anti-angiogenesis, prevention of metastasis, cell-cycle arrest, induction of apoptosis and moderation of the chemotherapy-induced deleterious side effects have been deduced as the key mechanisms of cancer manipulation. The components conferring antitumor potentials have been identified as caffeic acid phenethyl ester, chrysin, artepillin C, nemorosone, galangin, cardanol, etc. These compounds target various genetic and biochemical pathways of cancer progression. Depending on the botanical sources and the geographical origin, biological activities of propolis vary. Despite phenomenal development in cancer research, conventional therapy falls short in complete malignancy management. The findings obtained so far build hope that propolis as a complementary medicine may address the lacunae. This review documents the recent advances and scope of amendement in cancer remediation with adequate emphasis on the mechanistic aspect of propolis.

    The purpose of this study was to evaluate the differences in stage upon diagnosis, adherence to adjuvant treatment, and recurrence between rural and urban patients with early breast cancer. This retrospective study included 3640 patients with primary breast cancer recruited from 2000 to 2009. Patients who developed recurrence or metastasis were verified by adequate diagnostic imaging modalities and pathology. The χ 2 test was used to compare groups with respect to variables (recurrence and clinicopathologic features). A multivariable Cox proportional hazard regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for breast cancer recurrence risk. Compared with tumors in urban patients, those in rural patients showed higher histologic grade, larger size, more lymphatic metastasis, and higher Ki-67 index; therapy adherence was strongly associated with recurrence in both. Compared with urban patients, the female rural patients had a higher recurrence rate. However, no significant difference in recurrence rates was observed between urban and rural patients following guideline adherence. The results of our study suggest that the later stage upon diagnosis and nonadherence to treatment contribute toward worse breast cancer outcomes among rural patients with breast cancer. Adherence to needed adjuvant therapy could decrease recurrence rates for rural patients with early breast cancer. Copyright © 2016 Elsevier Inc. All rights reserved.

    2011-01-01

    Full Text Available Morphine has been used for many years to relieve cancer pain. Oral morphine (in either immediate release or modified release form remains the analgesic of choice for moderate or severe cancer pain. The dose of oral morphine is titrated up to achieve adequate relief from pain with minimal side effects. Antidepressant and anticonvulsant drugs, when used in addition to conventional analgesics, give excellent relief from cancer pain. Most cancer pain responds to pharmacological measures with oral morphine but some pain like neuropathic and bony pain, pain in children and elderly age group, and advanced malignancy pain are very difficult to treat. Here, we report the management of a similar patient of severe cancer pain and the difficulty that we came across during dose titration of oral morphine and adjuvant analgesic.

    An increasing number of neo-adjuvant breast cancer studies are being conducted and a novel model for tumor biological studies, the "window-of-opportunity" model, has revealed several advantages. Change in tumor cell proliferation, estimated by Ki67-expression in pre-therapeutic core biopsies versus post-therapeutic surgical samples is often the primary end-point. The aim of the present study was to investigate potential differences in proliferation scores between core biopsies and surgical samples when patients have not received any intervening anti-cancer treatment. Also, a lack of consensus concerning Ki67 assessment may raise problems in the comparison of neo-adjuvant studies. Thus, the secondary aim was to present a novel model for Ki67 assessment. Fifty consecutive breast cancer cases with both a core biopsy and a surgical sample available, without intervening neo-adjuvant therapy, were collected and tumor proliferation (Ki67, MIB1 antibody) was assessed immunohistochemically. A theoretical model for the assessment of Ki67 was constructed based on sequential testing of the null hypothesis 20% Ki67-positive cells versus the two-sided alternative more or less than 20% positive cells.. Assessment of Ki67 in 200 tumor cells showed an absolute average proliferation difference of 3.9% between core biopsies and surgical samples (p = 0.046, paired t-test) with the core biopsies being the more proliferative sample type. A corresponding analysis on the log-scale showed the average relative decrease from the biopsy to the surgical specimen to be 19% (p = 0.063, paired t-test on the log-scale). The difference was significant when using the more robust Wilcoxon matched-pairs signed-ranks test (p = 0.029). After dichotomization at 20%, 12 of the 50 sample pairs had discrepant proliferation status, 10 showed high Ki67 in the core biopsy compared to two in the surgical specimen (p = 0.039, McNemar's test). None of the corresponding results for 1000 tumor cells were

    Full Text Available Fareston (toremifene and tamoxifen, both selective estrogen receptor modulators, are therapeutically equivalent treatments for metastatic breast cancer. We hypothesized that toremifene as compared with tamoxifen given as adjuvant therapy for early stage breast cancer would result in equivalent survival with an improved side effect profile, therefore, providing superior therapeutic efficacy.Subjects and methods. The North American Fareston versus Tamoxifen Adjuvant trial assigned 1813 perimenopausal or postmenopausal women with hormone receptor (HR – positive invasive breast cancer to adjuvant treatment with either tamoxifen or toremifene. The primary outcomes evaluated were disease-free survival (DFS and overall survival (OS.Results. Median follow-up was 59 months. The baseline characteristics of the 2 treatment groups were well-balanced. On the basis of intenttotreat, 5-year actuarial DFS was not significantly different between tamoxifen and toremifene (91.2 % (standard error of the mean (SE 1.2 % vs 91.2 % (SE 1.1 %, respectively. Similarly, 5-year actuarial OS was not significantly different between tamoxifen and toremifene (92.7 % (SE 1.1 % vs 93.7 % (SE 1.0 %, respectively. Controlling for patient age, tumor size, and tumor grade, a Cox multivariate survival analysis found no difference between patients randomized to toremifene versus tamoxifen in terms of OS (OR 0.951; 95 % confidence interval (CI, 0.623–1.451, p = 0.951 or DFS (OR 1.037; 95 % CI, 0.721–1.491, p = 0.846. Adverse events were similar in the 2 groups.Conclusions. Women treated with adjuvant hormonal therapy enjoyed excellent DFS and OS. No significant differences were found between treatment with either tamoxifen or toremifene. Treatment of HR-positive patients with either tamoxifen or toremifene is appropriate.

    A positive circumferential resection margin (CRM) has been associated with a poorer prognosis in oesophageal and oesophagogastric junctional (OGJ) cancer. The College of American Pathologists defines the CRM as positive if tumour cells are present at the margin, whereas the Royal College of Pathologists also include tumour cells within 1 mm of this margin. The relevance of these differences is not clear and no study has investigated the impact of adjuvant therapy. The aim was to identify the optimal definition of an involved CRM in patients undergoing resection for oesophageal or OGJ cancer, and to determine whether adjuvant radiotherapy improved survival in patients with an involved CRM. This was a single-centre retrospective study of patients who had undergone attempted curative resection for a pathological T3 oesophageal or OGJ cancer. Clinicopathological variables and distance from the tumour to the CRM, measured to ± 0.1 mm, were correlated with survival. A total of 226 patients were included. Sex (P = 0·018), tumour differentiation (P = 0·019), lymph node status (P CRM distance (P = 0·042) were independently predictive of prognosis. No significant survival difference was observed between positive CRM 0-mm and 0·1-0·9-mm groups after controlling for other prognostic variables. Both groups had poorer survival than matched patients with a CRM at least 1 mm clear of tumour cells. Among patients with a positive CRM of less than 1 mm, those undergoing observation alone had a median survival of 18·6 months, whereas survival was a median of 10 months longer in patients undergoing adjuvant radiotherapy, but otherwise matched for prognostic variables (P = 0·009). A positive CRM of 1 mm or less should be regarded as involved. Adjuvant radiotherapy confers a significant survival benefit in selected patients with an involved CRM. © 2013 British Journal of Surgery Society Ltd. Published by John Wiley & Sons Ltd.

    Full Text Available Purpose: The aim of this study was to evaluate whether treatment with a local potent corticosteroid during adjuvant external radiotherapy (ERT of breast cancer is associated with late skin toxicity. Material and methods: Sixty patients (32 treated with potent corticoid cream versus 28 controls treated with moisturizer who had been included in a randomized study on prophylactic local corticosteroid treatment under adjuvant ERT in 2009 and 2010 were subjected to a follow-up study in 2016.Assessments of skin texture were registered according to the Late Radiation Morbidity Scoring Scheme (RTOG. Dryness, skin colour and skin thickness were objectively measured using non-invasive instruments. The patients were assessed for differences between their treated and untreated breasts. Results: Skin atrophy was not noticed in any of the 60 patients. Objective instrumental measurements did not reveal any significant differences in skin dryness, colour, pigmentation or skin thickness over the average follow-up time of six years. Clinical assessment based on the RTOG scoring system revealed that the odds ratio of having late skin problems in patients treated with moisturizer compared to patients treated with corticosteroid was 3.2 (95% CI: 1.0–10.1.Patients reported minor cosmetic dermatological sequelae. Seven patients developed telangiectasia, which caused cosmetic inconvenience. Conclusion: In this study, prophylactic corticosteroid treatment to ameliorate radiation dermatitis during adjuvant ERT of breast cancer was not associated with an increase in late skin toxicity nor did it result in skin atrophy. This study is limited by its small sample size, and the risk for false positive findings.

    During the past decade planning of adjuvant radiotherapy (RT) of early breast cancer has changed from two-dimensional (2D) to 3D conformal techniques. In the planning computerised tomography (CT) scan both the targets for RT and the organs at risk (OARs) are visualised, enabling an increased focus...... on target dose coverage and homogeneity with only minimal dose to the OARs. To ensure uniform RT in the national prospective trials of the Danish Breast Cancer Cooperative Group (DBCG), a national consensus for the delineation of clinical target volumes (CTVs) and OARs was required....

    To compare the efficacy of intravenous iron and oral iron for prevention of blood transfusions in gynecologic cancer patients receiving platinum-based chemotherapy. Sixty-four non anemic gynecologic cancer patients receiving adjuvant platinum-based chemotherapy were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. The study group received 200mg of intravenous iron sucrose immediately after each chemotherapy infusion. The control group received oral ferrous fumarate at a dose of 200mg three times a day. Complete blood count was monitored before each chemotherapy infusion. Blood transfusions were given if hemoglobin level was below 10mg/dl. There were 32 patients in each group. No significant differences in baseline hemoglobin levels and baseline characteristics were demonstrated between both groups. Nine patients (28.1%) in the study group and 18 patients (56.3%) in the control group required blood transfusion through 6 cycles of chemotherapy (p=0.02). Fewer median number of total packed red cell units were required in the study group compared to the control group (0 and 0.5 unit, respectively, p=0.04). Serious adverse events and hypersensitivity reactions were not reported. However, constipation was significantly higher in the control group (3.1% and 40.6%, p=gynecologic cancer patients receiving platinum-based chemotherapy, associated with less constipation than the oral formulation. © 2013 Elsevier Inc.

    Full Text Available Breast cancer is a life-threatening disease among women worldwide with annual rates of reported incidence and death increasing alarmingly. Chemotherapy is a recommended and effective treatment option for breast cancer; however, the narrow therapeutic indices and varied side effects of currently approved drugs present major hurdles in increasing its effectiveness. An increasing number of literature evidence indicate that complementary and alternative medicine (CAM used in treatment-related symptom control and alleviation of side effects plays an important role in increasing survival rate and quality of life in breast cancer patients. This review focuses on the use of herbal medicines and acupuncture in palliative care and as adjuvants in the treatment of breast cancer. Herbal medicinal treatments, the correlation of clinical use with demonstrated in vitro and in vivo mechanisms of action, and the use of certain acupoints in acupuncture are summarized. The aim of this review is to facilitate an understanding of the current practice and usefulness of herbal medicine and acupuncture as adjuvants in breast cancer therapy.

    Lung cancer is among the most important causes of death worldwide. Despite the relevant progresses in the personalized approach to lung cancer, patients' survival is still poor. Only a minor fraction of patients can be addressed to surgery for radical tumor removal. Adjuvant chemotherapy is currently recommended for resected stages II and III patients although it is known that it can modestly contribute to survival prolongation. A better identification of molecular markers, predictive of adjuvant chemo response is now mandatory, in order to reduce useless toxicities and identify those patients who could really benefit. Here we present and analyze a recent paper by Huang et al. aimed at evaluating the prognostic role of epidermal growth factor receptor (EGFR) activation in adjuvant setting in order to determine whether the administration of EGFR tyrosine-kinase inhibitors could improve the outcomes of patients affected by NSCLC undergoing complete resection. Moreover we provide an exhaustive literature revision that could be helpful for a proper management of that small cohort of EGFR-mutated resected NSCLC.

    Between 1977 and 1980, 118 breast cancer patients with locally advanced disease, T3B-4, any N, M0 or T1-3, tumor positive axillary apex biopsy, were randomized to one of three arms: I: radiotherapy (RT) to the breast and adjacent lymph node areas; II: RT followed by 12 cycles of cyclophosphamide, methotrexate, 5 fluorouracil (CMF) and tamoxifen during the chemotherapy period; III: 2 cycles of adriamycin and vincristine (AV), alternated with 2 cycles of CMF, then RT, followed by another 4 cycles of AV, alternated with 4 CMF; tamoxifen during the entire treatment period. The median follow-up period was 5 1/2 years. The adjuvant chemo- and hormonal therapy did not improve the overall survival; the 5-year survival was 37% for all three treatment arms. There was no statistically significant difference in RFS between the three modalities, nor when arm I was compared to arm II and III together. LR was not statistically different over the three treatment arms. In 18 of the 24 patients with LR, distant metastases appeared within a few months from the local recurrence. The menopausal status did not influence the treatment results. Dose reduction in more than 4 cycles of chemotherapy was accompanied by better results. In conclusion: adjuvant chemo- and hormonal therapy did not improve RFS and overall survival. These findings do not support the routine use of adjuvant chemo- and endocrine therapy for inoperable breast cancer

    To assess the impact of adjuvant treatment, sociodemographic and tumor factors on the survival of patients with non-metastatic clear cell endometrial carcinoma (CCC). 4298 patients treated from 1998 to 2011 with Stage I-IVA CCC were identified within the National Cancer Database. FIGO 2009 staging system was used. Adjuvant groups included: hysterectomy (HYS); HYS+vaginal brachytherapy (VBT); HYS+chemotherapy (CT); HYS+external beam radiation therapy (EBRT); HYS+CT+EBRT; and HYS+CT+VBT. Univariable (UVA) and multivariable (MVA) frailty survival analyses were performed. On UVA, higher stage was associated with an increased risk of death. Compared to stage I-IA, the risk of death for stage IB was HR 1.75 (95% CI, 1.50-2.04; pgeographic education attainment (p=0.001), greater comorbidity score (p=0.001), increasing age (pNational Cancer Center Database. Given the aggressive nature of the disease, clinical trials are required to determine the optimal adjuvant therapy in patients with non-metastatic CCC to improve clinical outcomes.

    For more than three decades, postoperative chemotherapy-initially fluoropyrimidines and more recently combinations with oxaliplatin-has reduced the risk of tumor recurrence and improved survival for patients with resected colon cancer. Although universally recommended for patients with stage III disease, there is no consensus about the survival benefit of postoperative chemotherapy in stage II colon cancer. The most recent adjuvant clinical trials have not shown any value for adding targeted agents, namely bevacizumab and cetuximab, to standard chemotherapies in stage III disease, despite improved outcomes in the metastatic setting. However, biomarker analyses of multiple studies strongly support the feasibility of refining risk stratification in colon cancer by factoring in molecular characteristics with pathologic tumor staging. In stage II disease, for example, microsatellite instability supports observation after surgery. Furthermore, the value of BRAF or KRAS mutations as additional risk factors in stage III disease is greater when microsatellite status and tumor location are taken into account. Validated predictive markers of adjuvant chemotherapy benefit for stage II or III colon cancer are lacking, but intensive research is ongoing. Recent advances in understanding the biologic hallmarks and drivers of early-stage disease as well as the micrometastatic environment are expected to translate into therapeutic strategies tailored to select patients. This review focuses on the pathologic, molecular, and gene expression characterizations of early-stage colon cancer; new insights into prognostication; and emerging predictive biomarkers that could ultimately help define the optimal adjuvant treatments for patients in routine clinical practice. © 2015 by American Society of Clinical Oncology.

    Full Text Available Background: Prognosis of stage IIIA N2 non-small cell lung cancer (NSCLC remains poor despite the changes in therapeutic strategies. Objectives: To assess long term results of neo adjuvant therapy followed by surgery for patients with stage IIIA N2 NSCLC and to analyze factors influencing survival. Materials and Methods: The methods adopted include: Retrospective review of medical records of 91 patients with stage IIIA N2 NSCLC, who received neo adjuvant therapy followed by surgery; collection of information on demographic information, staging procedure, preoperative therapy, clinical response, type of resection, pathologic response of tumor, status of lymph nodes and adjuvant chemotherapy; survival analysis by Kaplan-Meier and calculation of prognostic factors using log-rank and Cox regression model. Results: All patients received a platinum-based chemotherapy and 23 (29.1% had an associated radiotherapy. Eighty four patients underwent thoracotomy. Median survival was 26 months (95%CI, 22.6-30.8 months with three and five year survival rates of 31.6 and 20.9%, respectively. Prognostic factors for survival on univariate analysis was clinical response (P = 0.032, complete resection (P = 0.002, pathologic tumor response ( P < 0.001, and lymph nodal down staging (P = 0.001. Multivariate analyses identified complete resection, pathologic tumor response and lymph nodal down staging as independent prognostic factors. Conclusion: Survival of patients with stage IIIA N2 NSCLC who received neo adjuvant therapy is significantly influenced by clinical response, complete resection, pathologic tumor response, and lymph nodal down staging. These results can be helpful in guiding standard clinical practice and evaluating the outcome of neo adjuvant therapy followed by surgery in patients with stage IIIA N2 NSCLC.

    Full Text Available The cardiotoxic effects of adjuvant cancer treatments (i.e., chemotherapy and radiation treatment have been well documented, but the effects on peripheral cardiovascular function are still unclear. We hypothesized that cancer survivors i would have decreased resting endothelial function; and ii altered muscle deoxygenation response during moderate intensity cycling exercise compared to cancer-free controls. A total of 8 cancer survivors (~70 months post-treatment and 9 healthy controls completed a brachial artery FMD test, an index of endothelial-dependent dilation, followed by an incremental exercise test up to the ventilatory threshold (VT on a cycle ergometer during which pulmonary V̇O2 and changes in near-infrared spectroscopy (NIRS-derived microvascular tissue oxygenation (TOI, total hemoglobin concentration ([Hb]total, and muscle deoxygenation ([HHb] ≈ fractional O2 extraction were measured. There were no significant differences in age, height, weight, and resting blood pressure between cancer survivors and control participants. Brachial artery FMD was similar between groups (P = 0.98. During exercise at the VT, TOI was similar between groups, but [Hb]total and [HHb] were significantly decreased in cancer survivors compared to controls (P < 0.01 The rate of change for TOI (ΔTOIΔ/V̇O2 and [HHb] (Δ[HHb]/ΔV̇O2 relative to ΔV̇O2 were decreased in cancer survivors compared to controls (P = 0.02 and P = 0.03 respectively. In cancer survivors, a decreased skeletal muscle microvascular function was observed during moderate intensity cycling exercise. These data suggest that adjuvant cancer therapies have an effect on the integrated relationship between O2 extraction, V̇O2 and O2 delivery during exercise.

    Late effects of adjuvant treatment on perceived health and quality of life were assessed through a questionnaire mailed to 448 premenopausal and postmenopausal breast cancer patients, free from recurrence 2-10 years after primary therapy. The patients had been randomised to postoperative radiotherapy or adjuvant chemotherapy as adjuncts to primary surgery. The differences between the two treatments were generally small. However, the radiotherapy patients had significantly greater problems with decreased stamina, symptoms related to the operation scar and anxiety. The chemotherapy patients had significantly more problems with smell aversion. Activity level inside and outside the home, anxiousness and depressive symptoms were similar in both groups. The chemotherapy patients scored their overall quality of life higher than the radiotherapy patients. (author)

    PurposePrevious reports have shown the effectiveness of adjuvant hepatic arterial infusion chemotherapy (HAIC) in pancreatic cancer. However, percutaneous catheter placement is technically difficult after pancreatic surgery. The purpose of this study was to evaluate the feasibility and outcome of HAIC using a coaxial technique compared with conventional technique for postoperative pancreatic cancer.Materials and Methods93 consecutive patients who received percutaneous catheter-port system placement after pancreatectomy were enrolled. In 58 patients from March 2006 to August 2010 (Group A), a conventional technique with a 5-Fr indwelling catheter was used and in 35 patients from September 2010 to September 2012 (Group B), a coaxial technique with a 2.7-Fr coaxial catheter was used.ResultsThe overall technical success rates were 97.1 % in Group B and 86.2 % in Group A. In cases with arterial tortuousness and stenosis, the success rate was significantly higher in Group B (91.7 vs. 53.8 %; P = 0.046). Fluoroscopic and total procedure times were significantly shorter in Group B: 14.7 versus 26.7 min (P = 0.001) and 64.8 versus 80.7 min (P = 0.0051), respectively. No differences were seen in the complication rate. The 1 year liver metastasis rates were 9.9 % using the conventional system and 9.1 % using the coaxial system (P = 0.678). The overall median survival time was 44 months. There was no difference in the survival period between two systems (P = 0.312).ConclusionsThe coaxial technique is useful for catheter placement after pancreatectomy, achieving a high success rate and reducing fluoroscopic and procedure times, while maintaining the safety and efficacy for adjuvant HAIC in pancreatic cancer.

    Purpose: Population-based studies have reported that as many of 35% of black women do not undergo radiotherapy (RT) after breast conservation surgery (BCS). The objective of the present study was to determine whether this trend persisted at a large multidisciplinary cancer center, and to identify the factors that predict for noncompliance with RT and determine the outcomes for this subset of patients. Methods and Materials: Between January 2002 and December 2007, 83 black women underwent BCS at Memorial Sloan-Kettering Cancer Center and were therefore eligible for the present study. Of the 83 women, 38 (46%) had Stage I, 38 (46%) Stage II, and 7 (8%) Stage III disease. Of the study cohort, 31 (37%) had triple hormone receptor-negative tumors. RT was recommended for 81 (98%) of the 83 patients (median dose, 60 Gy). Results: Of the 81 women, 12 (15%) did not receive the recommended adjuvant breast RT. Nonreceipt of chemotherapy (p = .003) and older age (p = .009) were associated with nonreceipt of RT. With a median follow-up of 70 months, the 3-year local control, locoregional control, recurrence-free survival, disease-free survival, and overall survival rate was 99% (actuarial 5-year rate, 97%), 96% (actuarial 5-year rate, 93%), 95% (actuarial 5-year rate, 92%), 92% (actuarial 5-year rate, 89%), and 95% (actuarial 5-year rate, 91%), respectively. Conclusion: We found a greater rate of utilization adjuvant breast RT (85%) among black women after BCS than has been reported in recent studies, indicating that excellent outcomes are attainable for black women after BCS when care is administered in a multidisciplinary cancer center.

    Full Text Available Pooja Advani,1 Lauren Cornell,2 Saranya Chumsri,1 Alvaro Moreno-Aspitia1 1Division of Hematology and Oncology, 2Department of Internal Medicine, Mayo Clinic, Jacksonville, FL, USA Abstract: Human epidermal growth factor receptor 2 (HER2 is a tyrosine kinase transmembrane receptor that is overexpressed on the surface of 15%–20% of breast tumors and has been associated with poor prognosis. Consistently improved pathologic response and survival rates have been demonstrated with use of trastuzumab in combination with standard chemotherapy in both early and advanced breast cancer. However, resistance to trastuzumab may pose a major problem in the effective treatment of HER2-positive breast cancer. Dual HER2 blockade, using agents that work in a complimentary fashion to trastuzumab, has more recently been explored to evade resistance in both the preoperative (neoadjuvant and adjuvant settings. Increased effectiveness of dual anti-HER2 agents over single blockade has been recently reported in clinical studies. Pertuzumab in combination with trastuzumab and taxane is currently approved in the metastatic and neoadjuvant treatment of HER2-positive breast cancer. Various biomarkers have also been investigated to identify subsets of patients with HER2-positive tumors who would likely respond best to these targeted therapy combinations. In this article, available trial data regarding efficacy and toxicity of treatment with combination HER2 agents in the neoadjuvant and adjuvant setting have been reviewed, and relevant correlative biomarker data from these trials have been discussed.

    This article aims to review the risk stratification of endometrial cancer, treatment rationale, outcomes, treatment planning, and treatment recommendations of vaginal brachytherapy (VBT) in the post-operative management of endometrial cancer patients. The authors performed a thorough review of the literature and reference pertinent articles pertaining to the aims of this review. Adjuvant VBT for early stage endometrial cancer patients results in very low rates of vaginal recurrence (0–3.1%) with low rates of late toxicity which are primarily vaginal in nature. PORTEC-2 supports that VBT results in non-inferior rates of vaginal recurrence compared to external beam radiotherapy (EBRT) for the treatment of high-intermediate risk patients. VBT as a boost following EBRT, in combination with chemotherapy, and for high-risk histologies have shown excellent results as well though randomized data do not exist supporting VBT boost. There are many different applicators, dose-fractionation schedules, and treatment planning techniques which all result in favorable clinical outcomes and low rates of toxicity. Recommendations have been published by the American Brachytherapy Society and the American Society of Radiation Oncology to help guide practitioners in the use of VBT. Data support that patients and physicians both prefer joint decision-making regarding the use of VBT, and patients often desire additional treatment for a marginal benefit in risk of recurrence. Discussions regarding adjuvant therapy for endometrial cancer are best performed in a multi-disciplinary setting and patients should be counseled properly regarding the risks and benefits of adjuvant therapy.

    Randomized trials conducted in the 1980s have established the effectiveness of 5-fluorouracil-based adjuvant chemotherapy in treating stage-III colon cancer. However, the initiation of adjuvant chemotherapy is just the first step for survival improvement. Little is known about the actual completion rate of such a therapy in the community. The objectives of this study were to measure the initiation and completion rate of adjuvant chemotherapy and to identify the associated factors. We studied 12,265 patients aged 65+ diagnosed with stage-III colon cancer between 1991 and 2005 who were identified from the Surveillance, Epidemiology, and End Results-Medicare linked database. Chemotherapy initiation was defined as at least one claim indicating the use of chemotherapy. The first and last claims were used to measure the length of chemotherapy. A complete course of chemotherapy was defined as 8-13 months for 1991-1995 cohort and 5-7 months for 1996-2005 cohort according to clinical guideline. Of the 12,265 patients, 64.4% received adjuvant chemotherapy within 3 months after tumor resection. Among those who had chemotherapy initiated, 62.2% (or 38.0% of 12,265 patients) received a complete course of chemotherapy. Patient's age at diagnosis, marital status, and comorbidity score were the significant predictors for chemotherapy initiation. These variables remained significant in predicting chemotherapy completion after adjusting for year of diagnosis and other factors. In conclusion, initiation and completion of chemotherapy was largely influenced by patient's age, marital status and comorbidity. Further investigation is needed to explore the cause of these differences in adherence to standard treatment that is essential for better quality of cancer care.

    Purpose: To determine the impact of chemoradiation therapy (CRT) on overall survival (OS) after resection of pancreatic adenocarcinoma. Methods and Materials: A multicenter retrospective review of 955 consecutive patients who underwent complete resection with macroscopically negative margins (R0-1) for invasive carcinoma (T1-4; N0-1; M0) of the pancreas was performed. Exclusion criteria included metastatic or unresectable disease at surgery, macroscopic residual disease (R2), treatment with intraoperative radiation therapy (IORT), and a histological diagnosis of no ductal carcinoma, or postoperative death (within 60 days of surgery). In all, 623 patients received postoperative radiation therapy (RT), 575 patients received concurrent chemotherapy (CT), and 462 patients received adjuvant CT. Results: Median follow-up was 21.0 months. Median OS after adjuvant CRT was 39.9 versus 24.8 months after no adjuvant CRT (P<.001) and 27.8 months after CT alone (P<.001). Five-year OS was 41.2% versus 24.8% with and without postoperative CRT, respectively. The positive impact of CRT was confirmed by multivariate analysis (hazard ratio [HR] = 0.72; confidence interval [CI], 0.60-0.87; P=.001). Adverse prognostic factors identified by multivariate analysis included the following: R1 resection (HR = 1.17; CI = 1.07-1.28; P<.001), higher pT stage (HR = 1.23; CI = 1.11-1.37; P<.001), positive lymph nodes (HR = 1.27; CI = 1.15-1.41; P<.001), and tumor diameter >20 mm (HR = 1.14; CI = 1.05-1.23; P=.002). Multivariate analysis also showed a better prognosis in patients treated in centers with >10 pancreatic resections per year (HR = 0.87; CI = 0.78-0.97; P=.014) Conclusion: This study represents the largest comparative study on adjuvant therapy in patients after resection of carcinoma of the pancreas. Overall survival was better in patients who received adjuvant CRT.

    Although protracted cognitive impairment has been reported to occur after radiotherapy even when such therapy is not directed to brain areas, the mechanism remains unclear. This study investigated whether breast cancer patients exposed to local radiotherapy showed lower cognitive function mediated by higher plasma interleukin (IL)-6 levels than those unexposed. We performed the Wechsler Memory Scale-Revised (WMS-R) and measured plasma IL-6 levels for 105 breast cancer surgical patients within 1 year after the initial therapy. The group differences in each of the indices of WMS-R were investigated between cancer patients exposed to adjuvant regional radiotherapy (n = 51) and those unexposed (n = 54) using analysis of covariance. We further investigated a mediation effect by plasma IL-6 levels on the relationship between radiotherapy and the indices of WMS-R using the bootstrapping method. The radiotherapy group showed significantly lower Immediate Verbal Memory Index and Delayed Recall Index (P = 0.001, P = 0.008, respectively). Radiotherapy exerted an indirect effect on the lower Delayed Recall Index of WMS-R through elevation of plasma IL-6 levels (bootstrap 95% confidence interval = −2.6626 to −0.0402). This study showed that breast cancer patients exposed to adjuvant regional radiotherapy in conservation therapy might have cognitive impairment even several months after their treatment. The relationship between the therapy and the cognitive impairment could be partially mediated by elevation of plasma IL-6 levels. PMID:24756915

    Adjuvant therapy has become an integral component of the managment of primary high-risk breast cancer patients. However, a considerable fraction of women receive no benefit from this treatment. This study investigates whether a number of biopathological factors can influence the outcome of patients submitted to adjuvant chemotherapy involving the use of high-dose epirubicin and cyclophosphamide. One hundred and fifty-seven primary breast cancer patients, considered at high risk according to the St. Gallen Meeting Consensus Conference, were evaluated immunohistochemically for estrogen, progesterone receptors, p53, bcl-2, HER-2/neu, and Ki-67, of which the results were correlated with patient outcome. Results obtained demonstrated that p53 is a significant predictor of disease-free survival (DFS P < 0.0001) and overall survival (OS P = 0.0002) both in ductal and lobular carcinomas, whereas bcl-2 expression seems to be of prognostic value only in lobular carcinomas (DFS P = 0.01; OS P = 0.02). This data indicates that in high-risk breast cancer patients the immunohistochemical evaluation of p53 and bcl-2 may be of clinical value in distinguishing different responses to adjuvant anthracycline-based chemotherapy.

    Inhibiting the repair of radiation damage in the neoplastic cells and thus differentially increasing radiation damage can be one of the ways to improve efficiency of radiotherapy of cancer. The glucose antimetabolite 2-deoxy-D-glucose (2-DG) which is known to inhibit glycolysis and ATP production in different cell systems, has been studied as to its effects on energy supply and repair of radiation damage in wild type yeast cells which are analogous to normal cells, and in respirator-deficient (RD) mutants which are analogous to hypoxic tumour cells. Results indicate that : (1) 2-DG/glucose in molar cencentration ratio of 1 completely inhibits the repair of potentially lethal X-radiation damage in RD mutants, (2) 2-DG enhances repair of sublethal radiation damage in wild-type yeast cells, (3) 2-DG induces a sharp fall in ATP level in RD-mutants as compared to that in wild type cells, (4) 2-DG inhibits repair of potentially lethal X-radiation damage in Ehrlich ascites tumour cells, (5) 2-DG induces greater cell loss from the hypoxic as well as euoxic tumour cell population of sarcoma tumour-180 in mice, and (6) 2-DG increases the survival of normal mice when given whole-body gamma irradiaition. These results, therefore, show that 2-DG may differentially inhibit the repair process in tumours while enhancing repair in normal tissues. (M.G.B.)

    To evaluate factors associated with the lack of adjuvant chemotherapy after curative surgery in patients with stage II and III colon cancer based on national population-based data. A total of 8,412 patients diagnosed with stage II or III disease who underwent curative resection were included. Adjuvant chemotherapy was not administered in 3,057 cases (36.34%). Factors associated with the lack of chemotherapy were older age [hazard ratio (HR)=1.50 in patients 65-74 years and 5.23 in patients ≥75 years of age], female sex (HR=1.15), tumor-node-metastasis (TNM) stage II (HR=4.28), emergency surgery (HR=1.45), American Society of Anesthesiologists (ASA) score of 3 or higher (HR=1.62), fewer than 12 lymph nodes examined (HR=1.19), a greater quantity of transfusion (HR=1.08), and hospital type (tertiary referral center) (HR=1.62). Patient-related (older age, female sex, and ASA score of 3 or higher) and treatment-related factors (TNM stage II, emergency surgery, fewer than 12 lymph nodes examined, a greater quantity of transfusion, and hospital type) influenced the lack of adjuvant chemotherapy. Given that the use of adjuvant chemotherapy improves overall survival, physicians should make an effort to increase the proportion of patients receiving chemotherapy after surgery.

    Full Text Available Abstract Background A complete pathological response to neo-adjuvant chemo-radiation for oesophageal cancer is associated with favourable survival. However, such a benefit is seen in the minority. If one could identify, at diagnosis, those patients who were unlikely to respond unnecessary toxicity could be avoided and alternative treatment can be considered. The aim of this review was to highlight predictive markers currently assessed and evaluate their clinical utility. Methods A systematic search of Pubmed and Google Scholar was performed using the following keywords; "neo-adjuvant", "oesophageal", "trimodality", "chemotherapy", "radiotherapy", "chemoradiation" and "predict". The original manuscripts were sourced for further articles of relevance. Results Conventional indices including tumour stage and grade seem unable to predict histological response. Immuno-histochemical markers have been extensively studied, but none has made its way into routine clinical practice. Global gene expression from fresh pre-treatment tissue using cDNA microarray has only recently been assessed, but shows considerable promise. Molecular imaging using FDG-PET seems to be able to predict response after neo-adjuvant chemoradiation has finished, but there is a paucity of data when such imaging is performed earlier. Conclusion Currently there are no clinically useful predictors of response based on standard pathological assessment and immunohistochemistry. Genomics, proteomics and molecular imaging may hold promise.

    Full Text Available Breast cancer is a heterogeneous disease and may present with different clinical and biological characteristics. At present, breast cancer is divided into molecular subgroups besides its histopathological classification. Decision for adjuvant chemotherapy is made based on not only histopathological characteristics but also molecular and genomic characteristics using indices, guidelines and calculators in early-stage breast cancer. Making a treatment plan through all these prognostic and predictive methods according to risk categories aims at preventing unnecessary or useless treatments. In this review, an attempt to make a general assessment of prognostic and predictive methods is made which may be used for planning individualized therapy and also the comments of the guidelines used by the oncologists worldwide on these methods.

    Background: The Intergroup 0116 study showed a survival benefit with adjuvant chemoradiotherapy (CRT) for resected gastric cancer. We report our experience using conformal radiotherapy (RT). Methods and Materials: Eighty-two patients with resected gastric or gastroesophageal junction (GEJ) adenocarcinoma, Stage IB to IV (M0), were treated with 45 Gy in 25 fractions using a 5-field conformal technique. Chemotherapy was in accordance with the Intergroup 0116 study, or infusional 5-fluorouracil and cisplatin in a phase I/II trial. Results: Mean age was 56.4 years. Median follow-up was 22.8 months. Grade 3 or greater acute toxicity (National Cancer Institute Common Terminology Criteria of Adverse Events, version 3.0) was noted in 57% of patients (upper gastrointestinal tract 34%, hematologic 33%). One patient died of neutropenic sepsis. Radiation Therapy Oncology Group Grade 3 late toxicity included esophageal strictures (3 patients) and small bowel obstruction (1 patient). Full course CRT was completed by 67% of patients. Of 26 patients who relapsed, 20 died. Site of first relapse was available on 23 patients: 8 locoregional and distant, 4 locoregional alone, 11 distant alone. Overall and relapse-free survival were 69% and 54% at 3 years. Conclusion: Adjuvant CRT for gastric cancer, even with conformal RT, is associated with significant toxicity. Survival was comparable to that reported in the Intergroup 0116 study

    Purpose To determine the efficacy and complications of adjuvant vaginal high-dose-rate brachytherapy alone for patients with Stage I endometrial cancer in whom complete surgical staging had been performed. Methods and Materials Between April 1998 and March 2004, 100 patients with Stage I endometrial cancer underwent surgical staging (total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic ± paraaortic nodal sampling) and postoperative vaginal high-dose-rate brachytherapy at our institution. The total dose was 2100 cGy in three fractions. Results With a median follow-up of 23 months (range 2-62), no pelvic or vaginal recurrences developed. All patients underwent pelvic dissection, and 42% underwent paraaortic nodal dissection. A median of 29.5 pelvic nodes (range 1-67) was removed (84% had >10 pelvic nodes removed). Most patients (73%) had endometrioid (or unspecified) adenocarcinoma, 16% had papillary serous carcinoma, and 11% had other histologic types. The International Federation of Gynecology and Obstetrics stage and grade was Stage IA, grade III in 5; Stage IB, grade I, II, or III in 6, 27, or 20, respectively; and Stage IC, grade I, II, or III in 13, 17, or 10, respectively. The Common Toxicity Criteria (version 2.0) complications were mild (Grade 1-2) and consisted primarily of vaginal mucosal changes, temporary urinary irritation, and temporary diarrhea. Conclusion Adjuvant vaginal high-dose-rate brachytherapy alone may be a safe and effective alternative to pelvic external beam radiotherapy for surgical Stage I endometrial cancer

    Cancer vaccines mostly aim to induce cytotoxic T lymphocytes (CTLs) against tumors. An appropriate adjuvant is of fundamental importance for inducing cellular immune response. Since the antigen in particulate form is substantially more immunogenic than soluble form antigen, it is beneficial to interact with antigen-presenting cells membrane to induce robust CD8 + T cell activation following vaccination. Based on previous research, we designed an adjuvant formulation by combining Astragalus saponins, cholesterol, and liposome to incorporate antigen into a particulate delivery system, so as to enhance cellular immune response. Meanwhile, angiogenesis contributes to tumor growth and metastasis, and basic fibroblast growth factor (bFGF) is involved in tumor angiogenesis. Therefore, using lipo-saponins adjuvant formulation and a human recombinant bFGF antigen protein, we tried to induce bFGF-specific CTL response to inhibit tumor angiogenesis to achieve antitumor activity. After five immunizations, the lipo-saponins/bFGF complex elicited robust antibody response and markedly higher amount of interferon-γ in BALB/c mice, resulting in superior antitumor activities. Decreased microvessel density in CD31 immunohistochemistry and the lysis of vascular endothelial cells by the T lymphocytes from the immunized mice indicated that the immunity inhibited the angiogenesis of tumors and further led to the inhibition of tumors. Our data suggest that the approach to construct adjuvant formulation between liposome and Astragalus saponins appeared highly desirable, and that Astragalus saponins may be utilized as a valuable additive for enhancing the effectiveness of vaccines and stimulating an appropriate immune response that can benefit tumor therapy.

    Purpose: To determine the acceptability of short term neo-adjuvant maximal androgen deprivation (MAD) to patients treated with external beam radiation for locally advanced prostate cancer. Methods: Between 1996 and 2000, 818 patients with locally advanced, but non-metastatic, prostate cancer were entered into a randomised clinical trial (TROG 96.01), which compared radiation treatment alone with the same radiation treatment and 3 or 6 months neo-adjuvant MAD with goserelin and flutamide. Relevant symptoms, and how troublesome they were to the patient, were scored using a self-assessment questionnaire. This was completed by the patient at registration, and at specified times during and after treatment. Patients taking flutamide had liver function tests checked at regular intervals. Results: All patients have completed at least 12 months follow-up after treatment. Nearly all patients completed planned treatment with goserelin, but 27% of patients in the 6-month MAD treatment arm, and 20% in the 3-month arm, had to stop flutamide early. This was mainly due to altered liver function (up to 17% patients) and bowel side effects (up to 8% patients). However, although flutamide resulted in more bowel symptoms for patients on MAD, there was significant reduction in some urinary symptoms on this treatment. Acute bowel and urinary side effects at the end of radiation treatment were similar in all treatment arms. Side effect severity was unrelated to radiation target volume size, which was reduced by MAD, but symptomatology prior to any treatment was a powerful predictor. Of the 36% of patients who were sexually active before any treatment, the majority became inactive whilst on MAD. However, sexual activity at 12 months after radiation treatment was similar in all treatment arms, indicating that the effects of short term MAD on sexual function are reversible. Conclusion: Despite temporary effects on sexual activity, and compliance difficulties with flutamide, short-term neo-adjuvant

    Coexistence of breast cancer and tuberculosis is rare. In most cases, involvement by tuberculosis occurs in axillary lymph nodes. We report a case of a 43-years-old patient who had undergone adenomastectomy and left sentinel lymph node biopsy due to a triple negative ductal carcinoma. At the end of adjuvant treatment, the patient had an atypical lymph node in the left axilla. Lymph node was excised, and after laboratory analysis, the diagnosis was ganglion tuberculosis. The patient underwent treatment for primary tuberculosis. The development of these two pathologies can lead to problems in diagnosis and treatment. An accurate diagnosis is important to avoid unnecessary surgical procedures.

    >T and 1298A>C polymorphisms were not associated with survival or relapse-free survival (P > 0.2). The 677 CC genotype was associated to toxicity (odds ratio = 1.83, P = 0.01). Conclusions: The MTHFR 677C>T and 1298A>C polymorphisms probably do not predict efficacy of adjuvant 5-FU treatment in colorectal...... cancer after complete resection; however, the 677C>T polymorphism may be associated with lower toxicity in 5-FU treatment. Implementation of SNP analysis for these polymorphisms for individualized treatment is premature....

    Although physical activity (PA) can alleviate fatigue and improve quality of life (QoL) in patients with breast cancer (BC), not all domains of PA may have equal impact. The objective of the current study was to examine the longitudinal impact of PA components on the evolution of fatigue and QoL during and after adjuvant treatment for BC. The women included in the study were participants in the 2-year longitudinal FATSEIN ("Fatigue dans le cancer du Sein") study. Fatigue and QoL were measured using the Multidimensional Fatigue Inventory and the European Organization for Research and Treatment of Cancer 30-item QoL questionnaire, respectively. Group-based trajectory analysis was used to determine patterns of PA evolution (frequency, duration, and intensity). Cross-sectional and longitudinal associations between PA patterns and fatigue and QoL were analyzed by using multivariable linear regression and a mixed model. Among the 424 women who were included (mean ± standard deviation age, 57.1 ± 10.4 years), 2 trajectories were identified for each of the 3 PA components: low and insufficient frequency (51.2%) or regular and moderate frequency (48.8%), low and insufficient duration (47.6%) or regular and moderate duration (52.4%), and low intensity (47.2%) or low to moderate intensity (52.8%). Overall, during treatment, fatigue was increased and QoL was decreased, and the reverse was observed after treatment. During treatment, increased fatigue and decreased QoL were limited by regular PA frequency (β = -8.71 for total fatigue; β = 14.59 for emotional function), but the results were less significant after treatment. PA, especially its frequency, is an important determinant of fatigue and QoL during adjuvant treatment for BC. The promotion of regular PA among women who are receiving treatment for BC may be an effective way to reduce fatigue and improve QoL.

    Pre- and peri-operative strategies are becoming standard for the management of localized gastro-esophageal cancer. For localized gastric/gastro-esophageal junction (GEJ) cancer there are conflicting data that a peri-operative approach with cisplatin-based chemotherapy improves survival, with the benefits seen in esophageal cancer likely less than a 5-10% incremental improvement. Further trends toward improvement in local control and survival, when combined chemotherapy and radiation therapy are given pre-operatively, are suggested by recent phase III trials. In fit patients, a significant survival benefit with pre-operative chemoradiation is seen in those patients who achieve a pathologic complete response. In esophageal/GEJ cancer, definitive chemoradiation is now considered in medically inoperable patients. In squamous cell carcinoma of the esophagus, surgery after primary chemoradiation is not clearly associated with an improved overall survival, however, local control may be better. In localized gastric/GEJ cancer, the integration of bevacizumab with pre-operative chemotherapy is being explored in large randomized studies, and with chemoradiotherapy in pilot trials. The addition of anti-epidermal growth factor receptor and anti-human epidermal growth factor receptor-2 antibody treatment to pre-operative chemoradiation continues to be explored. Early results show the integration of targeted therapy is feasible. Metabolic imaging can predict early response to pre-operative chemotherapy and biomarkers may further predict response to pre-operative chemo-targeted therapy. A multimodality approach to localized gastro-esophageal cancer has resulted in better outcomes. For T3 or node-positive disease, surgery alone is no longer considered appropriate and neo-adjuvant therapy is recommended. The future of neo-adjuvant strategies in this disease will involve the individualization of therapy with the integration of molecular signatures, targeted therapy, metabolic imaging

    The anti-cancer mechanism of neo-adjuvant hormonal therapy (NHT) is not well understood. Lymphangiogenesis plays an important role in cancer progression and is regulated by a complex mechanism that includes vascular endothelial growth factor (VEGF) signaling. However, there is little information regarding relationship between lymphangiogenesis and androgen deprivation. The aim of this study was to clarify changes in lymphangiogenesis and VEGF expression induced by androgen deprivation in prostate cancer in vivo and in vitro. Patients who had undergone a radical prostatectomy were enrolled in the study (NHT, n = 60 and non-NHT, n = 64). Lymph vessels were identified by D2-40 immunoreactivity and lymph vessel density and lymph vessel area (LVD and LVA, respectively) were measured from micrographs. The expression of VEGF-A, -B, -C, and -D was evaluated by immunohistochemistry. The prognostic value of LVD and LVA for biochemical recurrence was also investigated. Mean LVD ± SD was higher in the NHT than in the non-NHT group (11.3 ± 3.0 vs. 7.1 ± 3.4 per high power field; P cancer cell line. LVA was found to be an independent predictor of biochemical recurrence in patients who received NHT. Our results demonstrate that NHT stimulates lymphangiogenesis via upregulation of VEGF-C and -D, which may increase LVA and affect the outcome of prostate cancer patients. This findings were supported by in vitro data of prostate cancer cell. Prostate 77:255-262, 2017. © 2016 The Authors. The Prostate Published by Wiley Periodicals, Inc. © 2016 The Authors.

    Cancer cells, relative to normal cells, demonstrate significant alterations in metabolism that are proposed to result in increased steady-state levels of mitochondrial-derived reactive oxygen species (ROS) such as O2•−and H2O2. It has also been proposed that cancer cells increase glucose and hydroperoxide metabolism to compensate for increased levels of ROS. Given this theoretical construct, it is reasonable to propose that forcing cancer cells to use mitochondrial oxidative metabolism by feeding ketogenic diets that are high in fats and low in glucose and other carbohydrates, would selectively cause metabolic oxidative stress in cancer versus normal cells. Increased metabolic oxidative stress in cancer cells would in turn be predicted to selectively sensitize cancer cells to conventional radiation and chemotherapies. This review summarizes the evidence supporting the hypothesis that ketogenic diets may be safely used as an adjuvant therapy to conventional radiation and chemotherapies and discusses the proposed mechanisms by which ketogenic diets may enhance cancer cell therapeutic responses.

    2017-01-01

    Full Text Available Treatment of breast cancer (BC is a complex multidisciplinary problem. Often, radiation therapy is an obligatory component of treatment of breast cancer patients. Numerous large randomized trials have proved the efficacy of adjuvant radiotherapy in both the standard fractionation regimen in a single focal dose of 2 Gy to a total focal dose of 50 Gy for 25 fractions and in modes of hypofractionation using radiation exposure at a larger daily dose with a reduction in the total treatment time. The presented review summarizes the data of the largest studies on the modes of hypofractionation of postoperative radiotherapy for breast cancer. Most of the studies comparing the standard mode of fractionation of postoperative radiotherapy with the modes of hypofractionation showed comparable results for the main oncological parameters with similar tolerability, frequency of complications and good cosmetic results. It also shows the economic feasibility of applying accelerated regimes in everyday practice. Despite the fact that radiotherapy in the mode of hypofractionation has already become the standard of treatment and is recommended for use by the largest European and American cancer associations, indications for its conduct, the criteria for selection in the studies and the range of recommended single focal doses differ. The obtained results do not give an opportunity to confidently judge the advantage of one or another regime. It is necessary to determine the factors of a favorable and unfavorable prognosis, to clarify the indications for the use of various radiotherapy techniques. Therefore, questions about the optimal mode of hypo-fractionation of adjuvant radiotherapy, the timing of its initiation and the criteria for selecting patients for this type of therapy as part of the comprehensive treatment of breast cancer have not yet been fully resolved. Also open is the choice of optimal single and total doses of radiation, its combination with drug

    Purpose: Adjuvant radiotherapy (RT) is often considered for endometrial cancer. We studied the effect of RT and surgical treatment on patients' quality of life (QOL). Methods and Materials: All patients referred to the gynecologic oncology clinics with biopsy findings showing endometrial cancer were recruited. QOL assessments were performed using the European Organization for Research and Treatment of Cancer QOL questionnaire-C30, version 3. Assessments were obtained at study entry and at regular 3-month intervals for a maximum of 2 years. Open-ended telephone interviews were done every 6 months. Linear mixed regression models were built using QOL domain scores as dependent variables, with the predictors of surgical treatment and adjuvant RT type. Results: A total of 40 patients were recruited; 80% of the surgeries were performed by laparotomy. Significant improvements were seen in most QOL domains with increased time from treatment. Adjuvant RT resulted in significantly more severe bowel symptoms and improvement in insomnia compared with conservative follow-up. No significant adverse effect from adjuvant RT was seen on the overall QOL. Bowel symptoms were significantly increased in patients treated with laparotomy compared with laparoscopy in the patients treated with whole pelvic RT. Qualitatively, about one-half of the patients noted improvements in their overall QOL during follow-up, with easy fatigability the most prevalent. Conclusion: No significant adverse effect was seen on patients' overall QOL with adjuvant pelvic RT after the recovery period. The acute adverse effects on patients' QOL significantly improved with an increasing interval from diagnosis.

    The fracture impact of adjuvant bisphosphonates in breast cancer is not defined with most trials reporting changes in bone mineral density as a surrogate. The AZURE trial (ISRCTN79831382) evaluated the impact of adjuvant zoledronic acid (ZOL) on fractures. The AZURE trial is an academic, multi-centre, randomised phase III study evaluating the addition of ZOL 4 mg to standard therapy (neo/adjuvant chemotherapy and/or endocrine therapy) for 5 years (administered by intravenous (iv) infusion every 3-4 weeks for 6 doses, then 3 monthly × 8 and 6 monthly × 5) in patients with stage II/III early breast cancer. Fracture data collected as part of skeletal-related adverse event reporting were analysed after a median of 84.2 months of follow-up and 966 disease-free survival (DFS) events. We assessed number of fractures, time-to-first fracture and the incidence of fractures before and after disease recurrence. Two hundred forty-four patients reported ≥1 fracture, 140 (8.3%) in the control arm (171 fractures) and 104 (6.2%) in the ZOL arm (120 fractures). Of the 291 fractures reported, 207 fractures occurred in the absence of recurrence (control 111, ZOL 96), 80 after recurrence (control 59, ZOL 21). The 5-year fracture rate was reduced from 5.9% (95%CI 4.8, 7.1%; control) to 3.8% (95%CI 2.9, 4.7%) with ZOL. ZOL significantly increased time-to-first fracture (HR 0.69, 95%CI 0.53-0.90; P = 0.0053) but the majority of fracture prevention benefit occurred after a DFS event (HR 0.3; 95%CI 0.17, 0.53; P < 0.001). Fracture benefits from ZOL were similar across menopausal sub-groups. In conclusion, adjuvant ZOL reduced the risk of clinical fractures, the majority of this protection occurred after disease recurrence. Copyright © 2018 Elsevier Ltd. All rights reserved.

    Endometrial cancer is a common female malignancy. Patients with high-risk endometrial cancer have relatively high incidence of metastasis and recurrence. Despite complete resection, patients with stage III or IV are at high risk of local or distant recurrence. Systemic adjuvant treatment includes chemotherapy and radiotherapy. But the optimal scheduling is not known. Recently proposed sequential chemo-radiotherapy as sandwich therapy for high risk endometrial cancer have yielded encouraging results. This article is to review the adjuvant chemo-radiotherapy in the "sandwich" method for high risk endometrial cancer to help clinicians identify the most effective adjuvant treatment for patients with high risks of it. We used MEDLINE, EMBASE, Cochrane Library and CBM databases to search the literature. A systematic review was made. And most data showed "sandwich" therapy is feasible, efficacious, well-tolerated and resulted in excellent long-term progression free and overall survival in the setting of advanced endometrial cancer. Randomized trials are necessary to compare chemo-radio therapy given in the "sandwich" fashion to other means of sequencing these treatment modalities. It is also necessary to define which population is best suited for "sandwich" adjuvant therapy.

    Triple-negative breast cancer (TNBC) constitutes a heterogeneous breast cancer subgroup with poor prognosis; survival rates are likely to be lower with TNBC compared to other breast cancer subgroups. For this disease, systemic adjuvant chemotherapy regimens often yield suboptimal clinical results. To improve treatment regimens in TNBC, identification of molecular biomarkers may help to select patients for individualized adjuvant therapy. Evidence has accumulated that determination of the methylation status of the PITX2 gene provides a predictive value in various breast cancer subgroups, either treated with endocrine-based therapy or anthracycline-containing chemotherapy. To further explore the validity of this novel predictive candidate biomarker, in the present exploratory retrospective study, determination of the PITX2 DNA-methylation status was assessed for non-metastatic TNBC patients treated with adjuvant anthracycline-based chemotherapy by molecular analysis of breast cancer tissues. The PITX2 DNA-methylation status was determined in fresh-frozen tumor tissue specimens (n=56) by methylation-specific qRT-PCR (qMSP) and the data related to disease-free and overall survival, applying an optimized DNA-methylation score of 6.35%. For non-metastatic TNBC patients treated with adjuvant systemic anthracycline-based chemotherapy, a low PITX2 DNA-methylation status (PITX2 DNA-methylation. For non-metastatic TNBC patients, selective determination of the PITX2 DNA-methylation status may serve as a cancer biomarker for predicting response to anthracycline-based adjuvant chemotherapy. The assay based on methylation of the PIXT2 gene can be applied to frozen and routinely available formalin-fixed, paraffin-embedded (FFPE) breast cancer tumor tissues that will not only define those TNBC patients who may benefit from anthracycline-based chemotherapy but also those who should be spared the necessity of such potentially toxic treatment. Such patients should be allocated to

    The purpose of this study was to assess the cardiac side effects, primarily the occurrence of ischemic heart disease, in symptom-free patients with early breast cancer treated with radiotherapy. Thirty-seven survivors of a former randomized study of early breast cancer were examined. Twenty patients irradiated pre- or postoperatively for left sided disease (study group patients) were compared with 17 controls who were either treated for right sided disease, or were nonirradiated patients. Radiotherapy was randomized in the original study; either tangential field 60 Co, or electron-therapy was delivered. Echocardiography and bicycle ergometry stress test with 99m Tc SestaMIBI myocardial perfusion scintigraphy were carried out and the patients' major risk factors for ischemic heart disease were also listed. Our results showed a significant difference between the scintigraphic findings of the two groups. Five of the 20 study group patients (25%), while none of the 17 controls exhibited some kind of significant defects on scintigraphy, indicating ischemic heart disease (p < 0.05). No deterioration in left ventricular systolic and/or diastolic function could be detected by echocardiography. Radiotherapy for left sided breast cancer with the mentioned treatment technique may present as an independent risk factor in the long-term development of ischemic heart disease, while left ventricular dysfunction could not be related to the previous irradiation. The authors emphasize the need to optimize adjuvant radiotherapy for early breast cancer by considering the dose both to the heart as well as the cancer. 39 refs., 4 tabs

    Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with oestrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial polyps, hyperplasia, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. To determine the effectiveness and safety of levonorgestrel intrauterine system (LNG-IUS) in pre- and postmenopausal women taking adjuvant tamoxifen following breast cancer for the outcomes of endometrial and uterine pathology including abnormal vaginal bleeding or spotting, and secondary breast cancer events. We searched the following databases: Cochrane Menstrual Disorders and Subfertility Group Specialised Register (MDSG), Cochrane Breast Cancer Group Specialised Register (CBCG), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Abstracts of Reviews of Effects (DARE), The Cochrane Library, clinicaltrials.gov, The World Health Organisation International Trials Registry, ProQuest Dissertations & Theses, MEDLINE, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycINFO, Web of Science, OpenGrey, LILACS, PubMed, and Google. The final search was performed in October 2015. Randomised controlled trials of women with breast cancer on adjuvant tamoxifen that compared endometrial surveillance alone (control condition) versus the LNG-IUS with endometrial surveillance (experimental condition) on the incidence of endometrial pathology. Study selection, risk of bias assessment and data extraction were performed independently by two review authors. The primary outcome measure was endometrial pathology (including polyps, endometrial hyperplasia, or endometrial cancer) diagnosed at hysteroscopy or

    Accurate breast cancer staging is essential for optimal management of adjuvant therapies. While breast lymphatic drainage involves both axillary and internal mammary (IM) lymph node (LN) basins, IM LN sampling is not routinely advocated. The current study analyzes the incidence of IM LN metastases sampled during free flap breast reconstruction and subsequent changes in adjuvant treatment. A retrospective analysis of patients with positive IM LN biopsies during free flap breast reconstruction was performed. Pre-reconstruction surgical and adjuvant therapies as well as staging and prognostic data were recorded. Change in adjuvant therapies based solely on IM LN positivity was determined. IM LN metastases were found on 28 (1.3%) out of 2057 patients and comprised the study population. Mean age was 49 years with pre-reconstruction chemotherapy or radiation administered in 50 or 54% of cases, respectively. Five (18%) patients had previously undergone lumpectomy with axillary sampling. Mean tumor size was 3.1 cm with tumor location evenly distributed among all four quadrants. Ten (36%) patients had isolated IM LN metastases Patients with both axillary and IM disease had larger lesions, increased prevalence of pre-reconstruction chemotherapy and radiation. Based exclusively on positive IM LN disease, 17 (63%) patients had a change in adjuvant therapy. Despite the low incidence of IM LN metastases, IM LN biopsy during free flap breast reconstruction is recommended. In 36% of cases, nodal metastases were isolated to the IM nodes. Identification of IM metastases influenced adjuvant therapies in a majority of cases.

    To find the applicability of adjuvant radiotherapy for extrahepatic bile duct cancer (EBDC), we analyzed the pattern of failure and evaluate prognostic factors of locoregional failure after curative resection without adjuvant treatment. In 97 patients with resected EBDC, the location of tumor was classified as proximal (n = 26) and distal (n = 71), using the junction of the cystic duct and common hepatic duct as the dividing point. Locoregional failure sites were categorized as follows: the hepatoduodenal ligament and tumor bed, the celiac artery and superior mesenteric artery, and other sites. The median follow-up time was 29 months for surviving patients. Three-year locoregional progression-free survival, progression-free survival, and overall survival rates were 50%, 42%, and 52%, respectively. Regarding initial failures, 79% and 81% were locoregional failures in proximal and distal EBDC patients, respectively. The most common site was the hepatoduodenal ligament and tumor bed. In the multivariate analysis, perineural invasion was associated with poor locoregional progression-free survival (p = 0.023) and progression-free survival (p = 0.012); and elevated postoperative CA19-9 (> or =37 U/mL) did with poor locoregional progression-free survival (p = 0.002), progression-free survival (p < 0.001) and overall survival (p < 0.001). Both proximal and distal EBDC showed remarkable proportion of locoregional failure. Perineural invasion and elevated postoperative CA19-9 were risk factors of locoregional failure. In these patients with high risk of locoregional failure, adjuvant radiotherapy could be considered to improve locoregional control.

    Colorectal carcinoma (CRC) with CpG island methylator phenotype (CIMP) is recognized as a distinct subgroup of CRC, and CIMP status affects prognosis and response to chemotherapy. Identification of CIMP status in CRC is important for proper patient management. In Eastern countries, however, the clinicopathologic and molecular characteristics and prognosis of CRCs with CIMP are still unclear. A total of 245 patients who underwent their first surgical resection for sporadic CRC were enrolled and CIMP status of the CRCs was determined using the quantitative MethyLight assay. The clinicopathologic and molecular characteristics were reviewed and compared according to CIMP status. In addition, the three-year recurrence-free survival (RFS) of 124 patients with stage II or stage III CRC was analyzed in order to assess the effectiveness of fluoropyrimidine-based adjuvant chemotherapy with respect to CIMP status. CIMP-high CRCs were identified in 34 cases (13.9%), and were significantly associated with proximal tumor location, poorly differentiated carcinoma, mucinous histology, and high frequencies of BRAF mutation, MGMT methylation, and MSI-high compared to CIMP-low/negative carcinomas. For patients with stage II or III CIMP-low/negative CRCs, no significant difference was found in RFS between those undergoing surgery alone and those receiving surgery with fluoropyrimidine-based adjuvant chemotherapy. However, for patients with CIMP-high CRCs, patients undergoing surgery with fluoropyrimidine-based adjuvant chemotherapy (n = 17; three-year RFS: 100%) showed significantly better RFS than patients treated with surgery alone (n = 7; three-year RFS: 71.4%) (P = 0.022). Our results suggest that selected patients with CIMP-high CRC may benefit from fluoropyrimidine-based adjuvant chemotherapy with longer RFS. Further large scale-studies are required to confirm our results

    Biliary tract cancer (BTC) is a dismal disease, even after curative intent surgery. We conducted this prospective, non-randomized phase II study to evaluate the feasibility and efficacy of cisplatin and gemcitabine as adjuvant treatment in patients with resected BTC. Patients initially received gemcitabine 1000 mg/m 2 alone on days 1, 8 and 15 every 28-days for a total of six cycles (single agent cohort), and after protocol amendment a combination therapy with gemcitabine 1000 mg/m 2 and cisplatin 25 mg/m 2 on days 1 and 8 was administered every 21 days for a total of eight cycles (combined regimen cohort). Treatment was planned to start within eight weeks after curative intent resection. Adverse events, disease-free survival and overall survival were assessed. Overall 30 patients were enrolled in the study from August 2008 and last patient was enrolled at 2nd December 2014. The follow-up of the patients ended at 31st December 2016. The first 9 patients received single-agent gemcitabine. The interim analysis met the predefined feasibility criteria and, from September 2010 on, the second group of 21 patients received the combination of cisplatin plus gemcitabine. In the single-agent cohort with gemcitabine the median relative dose intensity (RDI) was 100% (IQR 88.3-100). Patients treated with the combination cisplatin-gemcitabine received an overall median RDI of 100% (IQR 50-100) for cisplatin and 100% (IQR 75-100) for gemcitabine respectively. The most significant non-hematological adverse events (grade 3 or 4) were fatigue (20%), infections during neutropenia (10%), and two cases of biliary sepsis (7%). Abnormal liver function was seen in 10% of the patients. One patient died due to infectious complications during treatment with cisplatin and gemcitabine. The median disease-free survival (DFS) was 14.9 months (95% CI 0-33.8) with a corresponding 3-year DFS of 43.1 ± 9.1%. The median overall survival (OS) was 40.6 months (95% CI 18.8-62.3) with a 3-year

    Full Text Available Abstract Background Diagnosis of breast cancer during pregnancy was formerly considered an indication for abortion. The pendulum has since swung to the other extreme, with most reviews now rejecting termination while endorsing immediate anthracycline-based therapy for any pregnant patient beyond the first trimester. To assess the evidence for this radical change in thinking, a review of relevant studies in the fields of breast cancer chemotherapy, pregnancy, and drug safety was conducted. Discussion Accumulating evidence for the short-term safety of anthracycline-based chemotherapy during late-trimester pregnancy represents a clear advance over the traditional norm of therapeutic abortion. Nonetheless, the emerging orthodoxy favoring routine chemotherapy during gestation should continue to be questioned on several grounds: (1 the assumed difference in maternal survival accruing from chemotherapy administered earlier – i.e., during pregnancy, rather than after delivery – has not been quantified; (2 the added survival benefit of adjuvant cytotoxic therapy prescribed within the hormone-rich milieu of pregnancy remains presumptive, particularly for ER-positive disease; (3 the maternal survival benefit associated with modified adjuvant regimens (e.g., weekly schedules, omission of taxanes, etc. has not been proven equivalent to standard (e.g., post-delivery regimens; and (4 the long-term transplacental and transgenerational hazards of late-trimester chemotherapy are unknown. Summary Although an incrementally increased risk of cancer-specific mortality is impossible to exclude, mothers who place a high priority on the lifelong well-being of their progeny may be informed that deferring optimal chemotherapy until after delivery is still an option to consider, especially in ER-positive, node-negative and/or last-trimester disease.

    Two Web-based prognostic calculators (Adjuvant! and Numeracy) are widely used to individualize decisions regarding adjuvant therapy among patients with resected stage II and III colon cancer. However, these tools have not been directly compared. Hypothetical scenarios were formulated for the Numeracy calculator based on all potential combinations of age, lymph nodes status, tumor stage, and grade of tumor. These were then applied to three postsurgical therapy choices: observation, 5-fluorouracil (5-FU), or FOLFOX (5-FU, leucovorin, and oxaliplatin chemotherapy) to obtain the predicted 5-year disease-free survival (DFS) and overall survival (OS). Wilcoxon signed rank tests were used to compare the numerical predictions between the Adjuvant! and Numeracy calculators for each combination. A total of 192 hypothetical patient scenarios were obtained. For these patients, DFS and OS predictions from Adjuvant! were statistically significantly different than Numeracy (P <.05), except for four of 144 categories. While the estimated benefit in DFS and OS for 5-FU compared to surgery obtained from Adjuvant! and Numeracy were similar, the benefit in DFS and OS for FOLFOX over 5-FU, obtained from the Adjuvant! tool was slightly lower than that estimated from Numeracy. Among patients with resected stage II and III colon cancer, the DFS and OS estimates obtained from Numeracy and Adjuvant!, regarding the benefit of 5-FU over surgery, are similar, but the benefits of FOLFOX over 5-FU differ. Validation studies are needed to clarify the discrepancy and to assess the accuracy of these tools for predicting actual patient outcomes. Copyright 2010 Elsevier Inc. All rights reserved.

    A 74-year-old woman was diagnosed as having transverse colon cancer after diagnosis of nephrotic syndrome caused by membranous nephropathy. Although she had hypoproteinemia and hypoalbuminemia, we judged that she had no major nutritional problem. In previous, similar case reports, the use of human serum albumin and fresh-frozen plasma was suggested to be important to avoid complications in the perioperative period. Thus, we used the same in our patient in the perioperative period. In addition, we paid special attention to perioperative nutrition management and used total parenteral nutrition in perioperative period. We performed laparoscopic assisted right hemicolectomy. On the 15th day after the surgical resection, the patient was discharged without any problems. We considered that postoperative adjuvant chemotherapy with XELOX (CapeOX)should be performed because the TNM pathological stage was pStage III b. Regarding adjuvant chemotherapy for gastrointestinal cancer with nephrotic syndrome, no previous reports detailed the indications for postoperative adjuvant chemotherapy. Upon introduction of adjuvant chemotherapy, we determined adaptation in accordance with the general adaptation criteria. While observing the patient's progress with a nephrologist, we safely completed the scheduled 8 courses adjuvant chemotherapy.

    First-line postoperative adjuvant chemotherapies with S-1 and capecitabine and oxaliplatin (XELOX) were first recommended for resectable gastric cancer patients in the 2010 and 2011 Chinese NCCN Clinical Practice Guidelines in Oncology: Gastric Cancer; however, their economic impact in China is unknown. The aim of this study was to compare the cost-effectiveness of adjuvant chemotherapy with XELOX, with S-1 and no treatment after a gastrectomy with extended (D2) lymph-node dissection among patients with stage II-IIIB gastric cancer. A Markov model, based on data from two clinical phase III trials, was developed to analyse the cost-effectiveness of patients in the XELOX group, S-1 group and surgery only (SO) group. The costs were estimated from the perspective of Chinese healthcare system. The utilities were assumed on the basis of previously published reports. Costs, quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICER) were calculated with a lifetime horizon. One-way and probabilistic sensitivity analyses were performed. For the base case, XELOX had the lowest total cost ($44,568) and cost-effectiveness ratio ($7,360/QALY). The relative scenario analyses showed that SO was dominated by XELOX and the ICERs of S-1 was $58,843/QALY compared with XELOX. The one-way sensitivity analysis showed that the most influential parameter was the utility of disease-free survival. The probabilistic sensitivity analysis predicted a 75.8% likelihood that the ICER for XELOX would be less than $13,527 compared with S-1. When ICER was more than $38,000, the likelihood of cost-effectiveness achieved by S-1 group was greater than 50%. Our results suggest that for patients in China with resectable disease, first-line adjuvant chemotherapy with XELOX after a D2 gastrectomy is a best option comparing with S-1 and SO in view of our current study. In addition, S-1 might be a better choice, especially with a higher value of willingness-to-pay threshold.

    Purpose This prospective observational study aimed to evaluate the impact of adjuvant chemotherapy on biological and clinical markers of aging and frailty. Methods Women ≥ 70 years old with early breast cancer were enrolled after surgery and assigned to a chemotherapy (Docetaxel and Cyclophosphamide) group (CTG, n=57) or control group (CG, n=52) depending on their planned adjuvant treatment. Full geriatric assessment (GA) and Quality of Life (QoL) were evaluated at inclusion (T0), after 3 months (T1) and at 1 year (T2). Blood samples were collected to measure leukocyte telomere length (LTL), levels of interleukin-6 (IL-6) and other circulating markers potentially informative for aging and frailty: Interleukin-10 (IL-10), Tumor Necrosis Factor Alpha (TNF-α), Insulin-like Growth Factor 1 (IGF-1), Monocyte Chemotactic Protein 1 (MCP-1) and Regulated on Activation, Normal T cell Expressed and Secreted (RANTES). Results LTL decreased significantly but comparably in both groups, whereas IL-6 was unchanged at T2. However, IL-10, TNF-α, IGF-1 and MCP-1 suggested a minor biological aging effect of chemotherapy. Clinical frailty and QoL decreased at T1 in the CTG, but recovered at T2, while remaining stable in the CG. Conclusion Chemotherapy (TC) is unlikely to amplify clinical aging or induce frailty at 1 year. Accordingly, there is no impact on the most established aging biomarkers (LTL, IL-6). PMID:27102154

    Background and purpose: Induction chemotherapy prior to definitive concurrent chemoradiotherapy (CCRT) is a promising treatment option for unresectable head and neck cancer (HNC). In the postoperative setting, the efficacy of such an approach with adjuvant chemotherapy (AdjCT) followed by postoperative CCRT is unclear. Materials and methods: Forty-one postoperative patients with stage III-IV (M0) HNC enrolled on 3 consecutive phase II clinical trials were retrospectively analyzed. Twenty-five of the patients were treated on a protocol which included AdjCT with carboplatin and paclitaxel prior to postoperative CCRT (AdjCT group). Sixteen were treated on protocols with similar postoperative CCRT but without AdjCT (control group). CCRT consisted of paclitaxel, 5-fluorouracil, hydroxyurea, and twice-daily radiotherapy. Results: After a median follow-up of 72 months, there were no locoregional failures (LRF) or distant metastases (DM) in the AdjCT group. In the control group, there were 2 LRF and 2 DM. The 5-year risk of disease recurrence was 0% in the AdjCT group, compared to 28.9% in the control group (p = 0.0074). No patients had disease progression during AdjCT, and all proceeded to postoperative CCRT without delay. Conclusions: Adjuvant chemotherapy after surgery followed by CCRT may be a treatment strategy associated with favorable disease outcomes in locoregionally advanced HNC. These results pose a hypothesis which warrants further investigation.

    Full Text Available Objective: to reveal the benefits of adjuvant intravesical thermochemotherapy (TCT and to evaluate its efficiency in the treatment of moderateand high-risk non-muscle invasive bladder cancer (BC.Subjects and methods. In the period 2009 to 2010, the Urology Clinic, Federal Medical Biophysical Center, treated 21 patients with nonmuscle invasive BC, by using a Thermotron RF-8 clinical hyperthermal system. Intravesical TCT with mitomycin C 40 mg for 60–80 min was performed at 42 ± 2 °С as one session weekly for 6 weeks. Control cystoscopy was carried out every 3 months.Results. Of the 21 patients, 19 were found to tolerate the procedure well. No complications were recorded in these patients during the sessions and throughout the course of intravesical TCT. A recurrence was histologically verified in 2 patients at 6-month follow-up. There was no evidence suggesting a recurrence in 12 (57.14 % patients at one-year follow-up. The follow-up of the other patients is now less than 12 months.Conclusion. The proposed method of hyperthermia may be used as an alternative to the existing one of intracavitary hyperthermia to treat high- and moderate-risk BC and in case of inefficiency of other adjuvant therapy options for non-muscle invasive BC.

    The treatments for advanced non-small cell lung cancer (NSCLC) should control both local and microscopic systemic disease, because the 5-year survival of patients with Stage III NSCLC who underwent surgical resection alone has been dismal. One way to improve surgical outcome is the administration of chemotherapy before or after the surgical procedure. During the last two decades, many clinical studies have focused on developing optimal adjuvant or neoadjuvant chemotherapy regimens that can be combined with surgical treatment and/or radiotherapy. Based on the results of those clinical studies, multimodality therapy is considered to be an appropriate treatment approach for Stage IIIA NSCLC patients; although, optimal treatment strategies are still evolving. When N2 nodal involvement is discovered postoperatively, adjuvant cisplatin-based chemotherapy confers an overall survival benefit. The addition of postoperative radiotherapy might be considered for patients with nodal metastases. Although definitive chemoradiation remains a standard of care for cN2 NSCLC, alternative approaches such as induction chemotherapy or chemoradiotherapy and surgery can be considered for a selective group of patients. When surgical resection can be performed after induction therapy with low risk and a good chance of complete resection, the outcome may be optimal. The decision to proceed with resection after induction therapy must include a detailed preoperative pulmonary function evaluation as well as a critical intraoperative assessment of the feasibility of complete resection. © The Author 2017.

    Shared decision making (SDM) is widely advocated, especially for preference-sensitive decisions like those on adjuvant treatment for early-stage cancer. Here, decision making involves a subjective trade-off between benefits and side-effects, and therefore, patients' informed preferences should be

    This study suggests that cancer-related psychological or biological processes may adversely impact cognitive functioning and associated aspects of brain structure and function before the start of adjuvant treatment. Our findings stress the importance to further explore the processes underlying the expression of fatigue and to study whether it has a contributory role in subsequent treatment-related cognitive decline.

    Patient selection for organ sparing treatment after good response to neo-adjuvant chemoradiation (CRT) for locally advanced rectal cancer is challenging as no optimal restaging modality is available after CRT. In this study, we assessed the value of dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) for rectal cancer pathological response prediction. In 51 patients with locally advanced rectal cancer, the tumor volume and volume transfer constant (Ktrans) were obtained at 3 Tesla before CRT and surgery. The predictive potential for pathological complete response (pCR) and good response (GR) was assessed. GR was defined as pCR and near-pCR based on the tumor regression grade. The GR group consisted of 10 patients (19.6%) with six pCR (11.8%). Both the post-CRT tumor volume and post-CRT Ktrans values and the relative change in volume (ΔVolume) and Ktrans (ΔKtrans) were predictive for pathological response. ΔKtrans showed the best predictive potential with a positive predictive value (PPV) of 100% for GR using a cutoff value of 32% reduction in Ktrans. For pCR the best PPV was 80% with a multiparameter model containing ΔVolume and ΔKtrans. DCE-MRI has predictive potential for pathological response after CRT in rectal cancer with the relative ΔKtrans being the most predictive parameter. © 2014 Wiley Periodicals, Inc.

    Esophageal cancer (EC) is the fourth and sixth leading cause of cancer-related deaths in China and United States, respectively. The dismal prognosis of EC is mainly attributed to distant metastases, which may not be overcome by chemotherapy alone. Hence, the use of alternative adjuvant treatments, such as herbal medicines, for metastatic EC remains a great desire of patients. Our previous study demonstrated the in vivo anti-tumor and in vitro anti-invasion activities of Andrographis paniculata (AP) in esophageal cancer. In the present study, the chemical constituents of absorbed AP components through human intestinal Caco-2 cell monolayer were verified for the first time. The anti-migratory activities and suppressive effects on metastasis-related factors such as HER2, MMP2, MMP9, TM4SF3, CXCR4 of the absorbed AP components were revealed in esophageal cancer cells EC-109. The anti-tumor and anti-metastatic effects of AP water extract (1600 mg/kg) were further confirmed in metastatic esophageal xenograft-bearing mice. Besides, AP water extract acted synergistically with cisplatin plus 5-fluorouracil on inhibiting tumor nodule growth (with combination index present findings provide evidence on safety and advantages of the combined use of AP with chemotherapeutics in pre-clinical setting.

    Between 1/85 and 1/90, 14 consecutive patients were entered into a prospective study of conventional adjuvant post-operative external beam radiotherapy after complete resection for a pancreatic adeno-carcinoma. The surgical procedure was a Whipple resection in 9 patients, a distal pancrea-tectomy in 1 patient. There were 3 T[sub 1b], 8 T[sub 2] and 3 T[sub 3] tumors (UICC 1987); nodal involvement was present in 5 cases. The radiotherapy was delivered using a 4-field box technique with a 23 x MV photon beam. All patients received a total dose of 54 Gy to the tumor bed. The mean treated volume was 900 cm[sup 3]. Acute toxicities consisted mainly of weight loss (mean: 2 kg). Two patients had a grade 2 diarrhea and 2 patients a grade 2 gastritis. Late effects were minimal and only observed in 2 patients. The overall loco-regional recurrence (LR) rate was 50%. The median disease-free survival was 12 months, and the median survival was 23 months. This post-operative conventional radiotherapy treatment gives results that are comparable to the results of GITSG-adjuvant study using a combination of split-course radiotherapy and 5-fluorouracil (5-FU).

    The objective of the present study was to evaluate the efficacy of adjuvant androgen suppression in conjunction with external beam irradiation after radical prostatectomy in patients with pathologically confirmed extraprostatic disease. Between July 1988 and October 1999, 38 patients with pT3N0 or pT3N1 prostate cancer received adjuvant hormonal therapy and external beam irradiation following radical retropubic prostatectomy and pelvic lymphadenectomy. Administration of luteinizing hormone-releasing hormone analog or castration were initiated as an adjuvant androgen suppression within 4 weeks after surgery, whereas pelvic irradiation was performed at a median dose of 50 G within 3 months after surgery. The prognostic advantage of this combined adjuvant therapy was analyzed. During the median observation period of 92 months, biochemical recurrence occurred in four of the 38 patients and five patients died. Of these five patients, only one died of prostate cancer progression. The 10-year biochemical recurrence-free, cancer-specific and overall survival rates of the 38 patients were 86.7%, 90.9% and 78.7%, respectively. Among several factors examined, only tumor grade was significantly associated with biochemical recurrence-free survival in these patients; however, there were no factors that were independent predictors for biochemical recurrence, based on multivariate analysis. Furthermore, biochemical recurrence-free survival in the 38 patients was significantly superior to that in 54 patients with locally advanced disease who did not receive any postoperative therapies until biochemical recurrence; however, there was no significant difference in cancer-specific and overall survival between these two groups. Despite retrospective analysis with a relatively small number of patients, results of the present study suggest favorable effects of the combined adjuvant treatments with androgen ablation and pelvic irradiation on cancer control for patients with pT3N0 or pT3N1

LRFS, EFS and OS were significantly higher in the anthracycline group where the patients (n = 288 received more than 1 cycle of concurrent CT (P = .038, P = .026 and P = .038, respectively. LRFS and EFS were significantly higher in the anthracycline group within the BCT subgroup (P = .049 and P = .04, respectively. There were more hematologic, and more grade 2/3/4 skin toxicity in the anthracycline group. Conclusions After mastectomy or BCT, the adjuvant treatment based on anthracycline and concurrent RT reduced breast cancer relapse rate, and significantly improved LRFS, EFS and OS in the patients receiving more than 1 cycle of concurrent CT. There were more hematologic and non hematologic toxicities in the anthracycline group.

    The widespread introduction of high throughput RNA interference screening technology has revealed tumour drug sensitivity pathways to common cytotoxics such as paclitaxel, doxorubicin and 5-fluorouracil, targeted agents such as trastuzumab and inhibitors of AKT and Poly(ADP-ribose) polymerase (PARP......) as well as endocrine therapies such as tamoxifen. Given the limited power of microarray signatures to predict therapeutic response in associative studies of small clinical trial cohorts, the use of functional genomic data combined with expression or sequence analysis of genes and microRNAs implicated...... in drug response in human tumours may provide a more robust method to guide adjuvant treatment strategies in breast cancer that are transferable across different expression platforms and patient cohorts....

    Treatment of localized gastric cancer (LGC) consists of surgical resection followed by adjuvant treatment. Both chemoradiation (CRT) and chemotherapy (CT) regimens have shown benefit in survival outcomes versus observation. However, there are few data comparing these approaches. This study included consecutive patients with LGC treated at Instituto do Cancer do Estado de Sao Paulo (ICESP) from 2012 to 2015. CRT was based on the INT-0116 regimen and CT consisted of a platinum and fluoropyrimidine doublet. Treatment choice was based on physician preference. Toxicity was evaluated for every cycle. Overall survival (OS) analysis was performed by Kaplan-Meier. A propensity score-matched analysis was performed to minimize selection bias. A total of 309 patients were evaluated, 227 in CRT group and 82 in CT group. The most prevalent grade 3/4 toxicities in CRT and CT groups were: nausea/vomiting (9.25 vs 4.9%), fatigue (9.3% vs 2.4%), mucositis (4.4% vs 1.2%), neutropenia (37.8% vs 20.9%), febrile neutropenia (3.9% vs 0%), anemia (4.3% vs 6.1%), thrombocytopenia (2.6% vs 4.9%), neuropathy (0 vs 2.4%) and hand-foot syndrome (0.4% vs 2.4%). Two grade 5 toxicities (febrile neutropenia and anemia) occurred in CRT group. There was no difference in the pattern of recurrence. After a median follow-up of 23.5 months (CRT) and 20.6 months (CT), there was no difference in OS between groups. CT and CRT present similar efficacy and tolerability as adjuvant treatment for LGC.

    Purpose Factors associated with early mortality after surgery and treatment with adjuvant chemotherapy in colon cancer are poorly understood. We aimed to characterize the determinants of early mortality in a large cohort of colon cancer trial participants. Methods A pooled analysis of 37,568 patients in 25 randomized trials of adjuvant systemic therapy was conducted. Multivariable logistic regression models with several definitions of early mortality (30, 60, and 90 days, and 6 months) were constructed, adjusting for clinically and statistically significant variables. A nomogram for 6-month mortality was developed and validated. Results Median age among patients was 61 years, patient demographics included 54% men and 90% White, 29% and 71% had stage II and III disease, respectively, and 79%, 20%, and 1% had an Eastern Cooperative Oncology Group performance status (PS) of 0, 1, and ≥ 2, respectively. Early mortality was low: 0.3% at 30 days, 0.6% at 60 days, 0.8% at 90 days, and 1.4% at 6 months. Of those patients who died by 6 months post–random assignment, 40% had documented disease recurrence prior to death. Early disease recurrence was associated with a markedly increased risk of death during the first 6 months post-treatment (hazard ratio, 82.6; 95%CI, 66.9 to 102.1). In prognostic analyses, advanced age, male sex, poorer PS, increasing ratio of positive to examined lymph nodes, earlier decade of enrollment, and higher tumor stage and grade predicted a greater likelihood of early mortality, whereas treatment received was not strongly predictive. A multivariable model for 6-month mortality showed strong optimism-adjusted discrimination (concordance index, 0.73) and calibration. Conclusion Early mortality was infrequent but more prevalent in patients with advanced age and a PS of ≥ 2, underscoring the need to carefully consider the risk-to-benefit ratio when making treatment decisions in these subgroups.

It is clear that these drugs offer important efficacy benefits over tamoxifen and differ from tamoxifen in their safety profile. The accepted strategies for adjuvant AI therapy include initial adjuvant treatment following surgery, switching and/or sequencing from prior tamoxifen, and extended adjuvant therapy following the full 5 years of tamoxifen treatment. Among the available AIs, letrozole has been evaluated in large, well-controlled, double-blind clinical trials in the initial adjuvant, extended adjuvant, and more recently, the sequential adjuvant settings. Letrozole is the most potent of the AIs and provides near complete suppression of plasma estrogens in PMW. Letrozole also significantly reduces the occurrence of early distant metastases, the most lethal type of recurrence event, which can lead to improved survival. Clinical comparisons of letrozole with both tamoxifen and placebo have also provided important long-term safety data on the use of AIs as adjuvant therapy in PMW with EBC. The weight of clinical evidence indicates that letrozole is a safe and effective option for adjuvant hormonal therapy across all three AI treatment settings.Keywords: aromatase inhibitor, breast cancer, hormonal therapy, letrozole, postmenopausal women, tamoxifen

    Between January 1983 and December 1988, 218 female patients with known breast cancer and positive axillary nodes were treated with adjuvant radiotherapy and chemotherapy following radical mastectomy. Treatment results were retrospectively analysed at the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University of College of Medicine. The patients were classified into 3 groups; group 1 included 80 patients treated with adjuvant chemotherapy alone; in group 2, 52 patients treated with radiotherapy alone; and in group 3, 86 patients treated with combined chemo-radiotherapy. The mean age was 44 years and ranged from 27 to 70. The median follow-up time was 51 months. Seven-year relapse free and overall survival rates were 56% and 67%; in group 1, 50% and 56%; in group 2, 51% and 65%; and in group 3, 62% and 75% respectively. This difference was not statistically significant(p<0.05). The loco-regional failure rates were 13% and distant failure rates were 33%. There was less risk of loco-regional failure in group 2 and 3 which included radiotherapy (.0<0.05). But there was no significant y difference in the rates of distant failure(p>0.05). By univariate analysis, the only significant prognostic factor affecting relapse-free survival was the percentage of positive axillary nodes; and the overall survival significantly correlated with the primary tumor size, the number or percentage of positive axillary nodes, and stage. But in multivariate analysis, the only significant prognostic factor was treatment modality. By univariate analysis of prognostic factors affecting the rates of overall failure and distant failure, the significant prognostic factors was the percentage of positive axillary nodes; and the risk of the loco-regional failure significantly correlated with the treatment modality. In conclusion, these results suggest a potential for decreasing the risk of loco-regional failure with the addition of postoperative radiotherapy to chemotherapy in the

    Adjuvant chemotherapy for stage III colon cancer is internationally accepted as standard treatment with established efficacy. Several oral fluorouracil (5-FU) derivatives with different properties are available in Japan, but which drug is the most appropriate for each patient has not been established. Although efficacy prediction of 5-FU derivatives using expression of 5-FU activation/metabolism enzymes in tumors has been studied, it has not been clinically applied. The B-CAST study is a multicenter, prospective cohort study aimed to identify the patients who benefit from adjuvant chemotherapy with each 5-FU regimen, through evaluating the relationship between tumor biomarker expression and treatment outcome. The frozen tumor specimens of patients with stage III colon cancer who receives postoperative adjuvant chemotherapy are examined. Protein expression of thymidine phosphorylase (TP), dihydropyrimidine dehydrogenase (DPD), epidermal growth factor receptor (EGFR), and vascular endothelial growth factor (VEGF) are evaluated using enzyme-linked immunosorbent assay (ELISA). mRNA expression of TP, DPD, thymidylate synthase (TS) and orotate phosphoribosyl transferase (OPRT) are evaluated using reverse transcription polymerase chain reaction (RT-PCR). The patients’ clinical data reviewed are as follow: demographic and pathological characteristics, regimen, drug doses and treatment duration of adjuvant therapy, types and severity of adverse events, disease free survival, relapse free survival and overall survival. Then, relationships among the protein/mRNA expression, clinicopathological characteristics and the treatment outcomes are analyzed for each 5-FU derivative. A total of 2,128 patients from the 217 institutions were enrolled between April 2009 and March 2012. The B-CAST study demonstrated that large-scale, multicenter translational research using frozen samples was feasible when the sample shipment and Web-based data collection were well organized.

    The aim of this study was to compare two regimens of chemotherapy in patients with breast cancer, including FAC (doxorubicin, cyclophosphamide, and 5-fluorouracil) and TAC (docetaxel, doxorubicin and cyclophosphamide); and analyze the toxicity of these treatments and observe patient's health-related quality of life. Health-related quality of life was assessed for up to 4 months (from the beginning to the end of chemotherapy cycles), using European organization and cancer treatment quality of life questionnaire (EORTC) QLQ-C30. A group of 100 patients, with node-positive breast cancer were studied in order to compare the toxicity of adjuvant therapy TAC with FAC and the subsequent effects on the patient's quality of life. After a 4-month follow-up of patients, our findings showed that despite having the same mean score of QOL at the start of adjuvant chemotherapy, the QOL in TAC arm was decreased more as a result of the higher range of toxicity in TAC regimen. In spite of increase in disease-free patients who received TAC regimen and increase their survival rate, there is significant toxicity and decrease in QOL in TAC protocol compare to FAC protocol. Using prophylactic granulocyte colony stimulating factor (G-CSF) along with increased education aimed at improving patient's knowledge and also the provision of a supportive group involving psychiatrics and patients that have successfully experienced the same treatment may be helpful.

There is therefore a necessity for an adjuvant that maintains the quality of life (QOL and immune function of cancer patients receiving anthracycline-based chemotherapies.Patients and methods: The present study investigated the effectiveness of the concomitant use of Lentinula edodes mycelia extract (LEM, an oral immunomodulator, with FEC75 (5-fluorouracil + epirubicin + cyclophosphamide therapy on host QOL and immune function in breast cancer patients with nodal metastases. Ten breast cancer patients with nodal metastases receiving surgery were enrolled in this study. Treatment with 5-fluorouracil (500 mg/m2, epirubicin (75 mg/m2, and cyclophosphamide (500 mg/m2 was performed every 21 days for two courses, and LEM (1800 mg/day by mouth was administered during the second course.Results: In the first course, hematological toxicity was observed and host QOL and immune function were exacerbated. In the second course, however, the number of white blood cells and lymphocytes did not decrease and host QOL was maintained. Furthermore, the cytotoxic activities of natural killer (NK and lymphokine-activated killer cells and the proportion of activated NK and NK T-cells in lymphocytes were maintained in the second course.Conclusion: It has been suggested that the concomitant use of LEM with FEC75 therapy can maintain host QOL and immune function, and offer important implications for an application of LEM as a useful oral adjuvant to anthracycline-based chemotherapies

    A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials. (orig.) [de

    Current standard for most of the locally advanced rectal cancers is preoperative chemoradiotherapy, and, variably per institution, postoperative adjuvant chemotherapy. Short-course preoperative radiation with delayed surgery has been shown to induce tumour down-staging in both randomized and observational studies. The concept of neo-adjuvant chemotherapy has been proven successful in gastric cancer, hepatic metastases from colorectal cancer and is currently tested in primary colon cancer. Patients with rectal cancer with high risk features for local or systemic failure on magnetic resonance imaging are randomized to either a standard arm or an experimental arm. The standard arm consists of chemoradiation (1.8 Gy x 25 or 2 Gy x 25 with capecitabine) preoperatively, followed by selective postoperative adjuvant chemotherapy. Postoperative chemotherapy is optional and may be omitted by participating institutions. The experimental arm includes short-course radiotherapy (5 Gy x 5) followed by full-dose chemotherapy (capecitabine and oxaliplatin) in 6 cycles before surgery. In the experimental arm, no postoperative chemotherapy is prescribed. Surgery is performed according to TME principles in both study arms. The hypothesis is that short-course radiotherapy with neo-adjuvant chemotherapy increases disease-free and overall survival without compromising local control. Primary end-point is disease-free survival at 3 years. Secondary endpoints include overall survival, local control, toxicity profile, and treatment completion rate, rate of pathological complete response and microscopically radical resection, and quality of life. Following the advances in rectal cancer management, increased focus on survival rather than only on local control is now justified. In an experimental arm, short-course radiotherapy is combined with full-dose chemotherapy preoperatively, an alternative that offers advantages compared to concomitant chemoradiotherapy with or without postoperative

    This interview-based study uses phenomenology as a theoretical framework and thematic analysis to challenge existing explanatory frameworks of shared decision-making, in an exploration of women's experiences and perceptions of shared decision-making for adjuvant treatment in breast cancer. Three themes emerged are as follows: (1) women's desire to participate in shared decision-making, (2) the degree to which shared decision-making is perceived to be shared and (3) to what extent are women empowered within shared decision-making. Studying breast cancer patients' subjective experiences of adjuvant treatment decision-making provides a broader perspective on patient participatory role preferences and doctor-patient power dynamics within shared decision-making for breast cancer.

    The prognostic significance of the circumferential resection margin (CRM) status in oesophageal cancer patients treated with neo-adjuvant chemotherapy and radical resection is controversial. Furthermore, it is currently unclear whether patients with cancer located at the CRM have a prognosis different from that of those with cancer within 1 mm of the CRM. This is the first study aiming to establish the optimal tumour-free distance from the CRM of an oesophagectomy in patients who have undergone neo-adjuvant chemotherapy. The clinicopathological data of 232 oesophageal cancer patients from two UK centres were analysed. The CRM status was classified as Group A (cancer at the CRM), Group B (cancer within 1 mm but not at the CRM) and Group C (no cancer within 1 mm from the CRM). The relationship between the CRM status and patient survival was investigated. Thirty-eight specimens were classified as Group A, 89 as Group B and 105 as Group C. CRM status was related to the depth of tumour invasion (P CRM or within 1 mm of the CRM of the resected specimen have a significantly worse survival than patients with no cancer cells within 1 mm of the margin. However, this study suggests that the overall prognostic significance of the CRM status is limited in this cohort and the postoperative lymph node status is the most important prognostic factor in oesophageal cancer patients treated with neo-adjuvant chemotherapy and surgery.

    Impact of p16 protein, a surrogate marker for human papilloma virus induced cancer, p53 and EGFR as well as clinical factors on survival in a patient cohort with oropharyngeal squamous cell carcinoma (OPSCC) treated by surgical resection and adjuvant radiotherapy (RT) ± concomitant chemotherapy (CT). This is a retrospective analysis of patient's charts and tumor tissue. 57 patients were consecutively included and their tumor tissue assembled on a tissue microarray following immunohistochemical analysis. Survival times were estimated by means of Kaplan-Meier analysis. The importance of clinical and immunohistochemical factors for outcome was estimated by cox proportional hazard models. With 88% 5-year overall survival, 91% 5-year disease-specific survival and 91% 5-year disease-free survival, respectively, we found excellent survival rates in this surgically treated patient cohort of mainly advanced OPSCC (93% AJCC stage III or IV). The only factors positively influencing survival were p16 overexpression as well as p53 negativity and even more pronounced the combination of those biomarkers. Survival analysis of patients classified into three risk categories according to an algorithm based on p16, smoking, T- and N-category revealed a low, intermediate and high-risk group with significant survival differences between the low and the high-risk group. Patients with OPSCC can be successfully treated by surgery and adjuvant RT ± CT with a clear survival benefit of p16 positive, p53 negative patients. We recommend considering a combination of immunohistochemical (p16, p53) and clinical factors (smoking, T- and N-category) for risk stratification.

    Triple-negative [estrogen receptor (ER)-/progesterone receptor (PR)-/HER2-] breast cancer (TNBC) accounts for ∼ 15% of overall breast cancer and associated with a poor prognosis. There is a short of standard adjuvant chemotherapy regimens for TNBC. A number of studies have shown that TNBC might be sensitive to cisplatin and carboplatin on the basis that dysfunction of BRCA1 and its pathway is associated with a specific DNA-repair defect, but data of adjuvant setting about this is limited. From January 2010 to September 2011, 95 early triple-negative breast cancer patients confirmed by pathology were randomly assigned to receive TP (docetaxel 75 mg/m², carboplatin AUC = 5, day 1, 21 days a cycle for 6 cycles) or EC-T (epirubicin 90 mg/m², cyclophosphamide 600 mg/m², d1, 21 days a cycle for 4 cycles, followed by docetaxel 80 mg/m², d1, 21 days a cycle for 4 cycles) chemotherapy. Adjuvant radiation therapy was given selectively after chemotherapy. Here we report a preliminary safety analysis with the chi-square test. Seventy-six out of the 95 patients had completed the chemotherapy and could be assessed for the safety profiles of the regimens. Thirty-seven of them were in the EC-T group with a median age of 47 years, and 21 out of these 37 patients were premenopausal (56.8%). Another 39 patients came from the TP group with a median age of 46 years, and 22 out of these 39 patients were premenopausal (56.4%). All of the 37 patients in EC-T group completed the planned treatment whereas 2 patients of the 39 cases in TP group did not because of bone marrow suppression. During the treatments, 9 patients had dose adjustment in each group. Adverse events of grade 1/2 were common. Specific incidence of adverse events with grade 3/4 in each group was as follows: alopecia, 29.7% vs. 10.3% (P = 0.033), vomiting 21.6% vs. 7.7% (P = 0.085), leukopenia 54.1% vs.25.6% (P = 0.011) and neutropenia 51.4% vs. 35.9% (P = 0.174). Other grade 3/4 toxicities were rare. All the adverse

    Full Text Available Background and objective The efficacy of complete resection of the cancer for patients with stage IIIa non-small cell lung cancer (NSCLC is limited. Synthetic therapy is taken the lead in advocating at present. However, the value of post-operative radiotherapy is not still clear. The aim of this study is to evaluate the survival time and side effects of postoperative chemotherapy or chemoradiotherapy in the treatment of stage IIIa NSCLC. Methods Between December 2003 and June 2007, 52 cases that have completed followed-up data with stage IIIa of NSCLC received in the First Affiliated Hospital of Dalian Medical University. Twenty-three patients received postoperative chemoradiotherapy (group A and 29 patients received postoperative chemotherapy combined with radiotherapy (group B. Group A adopted platinum-based combination chemotherapy for 4-6 cycles. The chemotherapeutics included gemcitabine, vinorelbine and docetaxel. Group B used chemotherapy for 2-4 cycles and then received 3-dimensional conformal radiotherapy (3D-CRT. The prescribe dose of target volume was 50 Gy. The chemotherapy was same as for group A and needed 4 cycles in all. The impact of postoperative adjuvant treatment on survival and toxicity was observed in patients with stage IIIa NSCLC and the reason of disease progression was analyzed. Results The median survival was 32.5 months in group A and 31.9 months in group B (P=0.371. Progression-free survival extended about 6 months (P=0.044. The survival rate was 87% at 1 year, 0.1% at 2 year, 33% at 3 year for group A compared with 93%, 69%, 45% for group B. The major side effects were hematological and gastrointestinal toxicities, including nausea, vomiting and neutropenia. There was no significant difference in these toxicities between the two groups (P>0.05. Radioactiv esophageal infection occurred in 17.2% of the patients. Acute and late radioactive lung infection occurred in 13.8% and 27.6% of the patients. All these toxicities

    Decision-making regarding adjuvant chemotherapy has been based on clinical and pathological features. However, such decisions are seldom consistent. Web-based predictive models have been developed using data from cancer registries to help determine the need for adjuvant therapy. More recently, with the recognition of the heterogenous nature of breast cancer, genomic assays have been developed to aid in the therapeutic decision-making. We have carried out a comprehensive literature review regarding online prognostication tools and genomic assays to assess whether online tools could be used as valid alternatives to genomic profiling in decision-making regarding adjuvant therapy in early breast cancer. Breast cancer has been recently recognized as a heterogenous disease based on variations in molecular characteristics. Online tools are valuable in guiding adjuvant treatment, especially in resource constrained countries. However, in the era of personalized therapy, molecular profiling appears to be superior in predicting clinical outcome and guiding therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

    Patients with luminal HER2-negative tumours have a favourable prognosis. However, there is a subpopulation in which poorer outcomes are obtained with endocrine therapy alone. This subpopulation is considered to benefit from chemotherapy. However, the significance of chemotherapy for those with luminal tumours has decreased due to recent changes in treatment strategies. Thus, it is often difficult to determine whether we should recommend chemotherapy to such patients in clinical practice. We investigated Ki67 expression, as a means of predicting the responses of luminal HER2-negative breast cancer patients to neo-adjuvant chemotherapy (NAC), in order to identify a subpopulation that would benefit from these treatments. We enrolled 114 luminal HER2-negative breast cancer patients undergoing surgery after NAC. Biomarkers were examined using biopsy specimens obtained prior to treatment, to avoid any chemotherapy-related effects. Chemotherapy effects were determined employing operative specimens and we defined pathological complete response (pCR) as invasive nest disappearance, based only on the primary breast tumour. We applied receiver operating characteristic curve analysis to data from our 114 patients, to investigate Ki67 expression as a predictor of pCR. The pCR rate was significantly higher for tumours with high Ki67 expression (p Ki67 cut-off value which distinguishes those with a pCR from other cases. Another dataset, comprised of 196 patients with a median 29-month observation period, was recruited for validation. Disease-free survival was found to be significantly (p Ki67 expression was higher than 35%. Our results raise the possibility of the luminal HER2-negative subpopulation with Ki67 expression higher than 35% benefiting from chemotherapy, as evidenced by improved survival.

    The aim of the study was to compare our reference adjuvant chemotherapy, FEC100 (fluorouracil 500 mg m−2, epirubicin 100 mg m−2 and cyclophosphamide 500 mg m−2, six cycles every 21 days), to an epirubicin–vinorelbine (Epi-Vnr) combination for early, poor-prognosis breast cancer patients. Patients (482) were randomised to receive FEC100, or Epi-Vnr (epirubicin 50 mg m−2 day 1 and vinorelbine 25 mg m−2, days 1 and 8, six cycles every 21 days). The 7-year disease-free survival rates were 59.4 and 58.8%, respectively (P=0.47). The relative dose intensity of planned epirubicin doses was 89.1% with FEC100 and 88.9% with Epi-Vnr. There were significantly more grades 3–4 neutropenia (P=0.009) with Epi-Vnr, and significantly more nausea-vomiting (P<0.0001), stomatitis (P=0.0007) and alopecia (P<0.0001) with FEC100. No cases of congestive heart failure were reported, whereas four decreases in left ventricular ejection fraction occurred after FEC100 and five after Epi-Vnr. One case of acute myeloblastic leukaemia was registered in the FEC100 arm. After 7 years of follow-up, there was no difference between treatment arms. Epi-Vnr regimen provided a good efficacy in such poor-prognosis breast cancer patients, and could be an alternative to FEC100, taking into account respective safety profiles of both regimens.

    Purpose: Most patients with localized breast cancer (LBC) who take adjuvant chemotherapy (CT) complain of fatigue and a decrease in quality of life during or after radiotherapy (RT). The aim of this longitudinal study was to compare the impact of RT alone with that occurring after previous CT on quality of life. Methods and Materials: Fatigue (the main endpoint) and cognitive impairment were assessed in 161 CT-RT and 141 RT patients during RT and 1 year later. Fatigue was assessed with Functional Assessment of Cancer Therapy-General questionnaires, including breast and fatigue modules. Results: At baseline, 60% of the CT-RT patients expressed fatigue vs. 33% of the RT patients (p <0.001). Corresponding values at the end of RT were statistically similar (61% and 53%), and fatigue was still reported at 1 year by more than 40% of patients in both groups. Risk factors for long-term fatigue included depression (odds ratio [OR] = 6), which was less frequent in the RT group at baseline (16% vs. 28 %, respectively, p = 0.01) but reached a similar value at the end of RT (25% in both groups). Initial mild cognitive impairments were reported by RT (34 %) patients and CT-RT (24 %) patients and were persistent at 1 year for half of them. No biological disorders were associated with fatigue or cognitive impairment. Conclusions: Fatigue was the main symptom in LBC patients treated with RT, whether they received CT previously or not. The correlation of persistent fatigue with initial depressive status favors administering medical and psychological programs for LBC patients treated with CT and/or RT, to identify and manage this main quality-of-life-related symptom.

    This study describes the communication style preferences of Japanese patients when receiving bad news, examines the factor structure of the measure for patients' preferences (MPP) in a Japanese population, and explores variables that may be associated with patients' communication style preferences. Five hundred twenty-nine cancer outpatients completed several psychosocial measures including the Japanese version of the MPP (MPP-J), the Mental Adjustment to Cancer Scale (MAC), and the Hospital Anxiety and Depression Scale (HADS). The patients desired detailed information and a supportive environment when receiving bad news. The MPP-J demonstrated a 5-factor structure: support, facilitation, medical information, clear explanation, and encouraging question-asking. Regression analyses indicated that a female gender, the fighting spirit and anxious preoccupation dimensions of the MAC were positively associated with all 5 MPP-J factors. In conclusion, Japanese cancer patients' preferences for communication when receiving bad news differ somewhat from those of American patients. Japanese physicians should encourage patients to ask questions and should consider the demographic (e.g. gender), medical (disease status) and psychosocial characteristics (fighting spirit and anxious preoccupation) of patients when delivering bad news.

    Constipation occurs in children receiving chemotherapy for cancer but there are no data about prevalence, risk factors, and severity of constipation in this group of children. We prospectively studied 61 children receiving chemotherapy for cancer. We administered questionnaires to children and parents and collected data on demographics, chemotherapy, and bowel movement pattern during chemotherapy. We used North American Society of Pediatric Gastroenterology, Hepatology, and Nutrition criteria for the diagnosis of constipation. Parental perception of constipation as a problem and impact on lifestyle during chemotherapy were assessed on a 0 to 3 scale with 0 being no problem, 1 minor, 2 significant, and 3 being a major problem. Thirty-five children (57%) had acute constipation lasting for 2 or more weeks during chemotherapy. Several risk factors were analyzed and only combined use of vincristine and opiates emerged as significant risk factor for the development of constipation. In children with constipation, 15 of 35 parents (43%) perceived constipation as a major/significant problem and 8 children and their parents (23%) perceived constipation having a major/significant impact on lifestyle during chemotherapy. Acute constipation was diagnosed in 57% of children receiving chemotherapy for cancer. Combined use of vincristine and opiates was associated with the development of constipation. Constipation can be a significant problem with a negative impact on lifestyle during chemotherapy and needs aggressive management.

    The benefit of adjuvant trastuzumab with chemotherapy is well established for women with higher risk human epidermal growth factor receptor 2-positive (HER2 + ) breast cancer. However, its role in older patients with smaller, node-negative tumors is less clear. We conducted a retrospective, sequential cohort study of this population to describe the impact of trastuzumab on breast cancer outcomes and cardiac safety. Women ≥ 55 years with ≤ 2 cm, node-negative, HER2 + breast cancer were identified and electronic medical records reviewed. A no-trastuzumab cohort of 116 women diagnosed between January 1, 1999 and May 14, 2004 and a trastuzumab cohort of 128 women diagnosed between May 16, 2006 and December 31, 2010 were identified. Overall survival and distant relapse-free survival were estimated by Kaplan-Meier methods. The median ages of the trastuzumab and no-trastuzumab cohorts were 62 and 64 years, respectively. More patients in the trastuzumab cohort had grade III (P = .001), lymphovascular invasion (P = .001), or estrogen receptor-negative (P cancers. The majority of the trastuzumab cohort received chemotherapy versus one-half of the no-trastuzumab cohort (98% vs. 53%; P women in the trastuzumab cohort and 1 in the no-trastuzumab cohort developed symptomatic heart failure. There were no cardiac-related deaths in either arm. Following adjuvant trastuzumab with chemotherapy, selected older women with small, node-negative, HER2 + breast cancers have excellent disease control. The rate of cardiac events is low.

    Chemotherapy (CT) is an important adjuvant treatment that has been widely used for breast cancer (BC) patients. However, no research has focused on trends in emotions and quality of life (QOL) during intermittent periods between CT sessions that are critical for recovery. The aim of this study was to investigate longitudinal trends in anxiety, depression, and QOL during the different intermittent periods between adjuvant CT for BC. A longitudinal study design was adopted. Eighty-eight women undergoing CT for BC were selected using a purposive sampling method, and they completed the Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), and Functional Assessment of Cancer Therapy-Breast (FACT-B) at 5 points. A repeated-measures analysis-of-variance model was used to compare anxiety, depression, and QOL at different time points. The results showed a significant difference in SAS (F = 187.78, P fashion.

    Adrenocortical cancer is one of the most aggressive endocrine malignancies. Growth through the capsule or accidental release of cancer cells during surgery frequently results in metastatic disease. We investigated the antitumoral effect of 2 adrenocorticolytic compounds, O, P'-DDD and MeSO2-DDE, in the adrenocortical cell line H295R both in vitro and as a xenograft model in vivo. H295R cells were injected s. c. in nude mice. O, P'-DDD, MeSO2-DDE, or oil (control) was administered i. p., either simultaneously with cell injection at day 0 (mimicking adjuvant treatment), or at day 48 (established tumors). Accumulation of PET tracers [ (11)C]methionine (MET), [ (11)C] metomidate (MTO), 2-deoxy-2-[ (18)F]fluoro-d-glucose (FDG), and [ (18)F]-l-tyrosine (FLT) in the aggregates were assessed +/- drug treatment in vitro. Tumor growth was significantly inhibited when O, P'-DDD was given at the same time as injection of tumor cells. No significant growth inhibition was observed after treatment with O, P'-DDD at day 48. A significant reduction in FLT uptake and an increased FDG uptake, compared to control, were observed following treatment with 15 microM O, P'-DDD (p<0.01) in vitro. MeSO2-DDE (15 microM) treatment gave rise to a reduced MET and an increased FLT uptake (p<0.01). Both compounds reduced the uptake of MTO compared to control (p<0.01). Treatment with O, P'-DDD simultaneously to inoculation of H295R cells in mice, imitating release of cells during surgery, gave a markedly better effect than treatment of established H295R tumors. We suggest that FLT may be a potential PET biomarker when assessing adrenocortical cancer treatment with O,P'-DDD. Further studies in humans are needed to investigate this.

    This study aims to investigate the efficacy of neo-adjuvant chemotherapy with TEC regimen (taxotere-epirubicin-cyclophosphamide) in the treatment of breast cancer (BC) patients. Total of 118 BC patients were recruited from the Department of Breast Surgery in Shengjing Hospital of China Medical University from January 1, 2010 to December 31, 2012, in this study. The clinical data and serum samples were collected from each patient prior to the study. All patients were given four cycles of TEC chemotherapy before surgery. The overall response rate of TEC regimen in the treatment of BC was 67.8% (80/118), clinical complete response rate was 3.4% (4/118), and clinical partial response rate was 64.4% (76/118). Furthermore, we found that age, tumor size, lymph node metastasis and clinical stages of patients had no statistically significant difference (all P > 0.05). Both negative ER status and negative PR status were statistically related to better response (P = 0.033 and P = 0.024, respectively) when compared with the positive ER status and positive PR status, while such association was not observed between the negative HER-2 status and positive HER-2 status (P > 0.05). In addition, the efficacy of triple-negative breast cancer was significantly better than that of luminal A, luminal B and HER-2+ cancers (all P 0.05). Our study support the view that BC cases under the TEC chemotherapy were related to higher overall response rates; and the chemotherapy with the TEC regimen could be served as an effective therapy in the treatment of BC.

    The study included 128 patients with stage T2-4N0-3M0 locally advanced breast cancer. All patients were divided into two groups. Group I (study group) consisted of 68 patients, who received neutron therapy, and group II (control group) comprised 60 patients, who received electron beam therapy. Neutron therapy was well tolerated by the patients and 1-2 grade radiation skin reactions were the most common. Neutron therapy was shown to be effective in multimodality treatment of the patients with locally advanced breast cancer. The 8-year recurrence-free survival rate in the patients with locally advanced breast cancer was 94.5 ± 4.1% after neutron therapy and 81.4 ± 5.9% after electron beam therapy (p = 0.05).

    Purpose: To assess cardiac mortality, coronary artery disease, myocardial dysfunction, and valvular heart disease in women younger than 65 years of age, at least 10 years after adjuvant radiotherapy following mastectomy in early breast cancer. Methods and Materials: Ninety women (45-64 years old) with Stage II breast cancer without relapse, included in the South Sweden Breast Cancer Trial (premenopausal arm), with or without adjuvant postoperative radiotherapy ± cyclophosphamide were examined with myocardial scintigraphy and echocardiography/Doppler, 10-17 years after radiotherapy. Thirty-four patients had been irradiated for left-sided tumors, 33 for right-sided tumors, and 23 patients had not been treated with radiotherapy. The radiotherapy (conventional roentgen, electron beams, and high-energy photon beams combined, in each patient) included the chest wall and the regional lymph nodes, with a specified target dose of 38-48 Gy, administered in daily fractions of 1.9-2.4 Gy, 5 days/week. Results: No cardiac deaths were found among the original 275 patients randomized to adjuvant therapy. In the 90 patients examined, abnormal findings were recorded for ECG (14 patients), exercise test (5 patients), myocardial scintigraphy (6 patients), thickening of valve cusps (14 patients), and mild valvular regurgitation (20 patients). All patients had normal systolic function. Diastolic dysfunction was observed in 6 patients (abnormal relaxation in 4 patients and restrictive filling abnormality in 2 patients). Although no significant differences were found between the 3 study groups, there was a tendency to more abnormal findings after radiotherapy. Conclusion: Women younger than 50 years of age at the time of adjuvant radiotherapy following mastectomy in early breast cancer, had no serious cardiac sequelae 13 years (median) later, despite partly old-fashioned radiation techniques

    Rectal cancer surgery is accompanied with high morbidity and poor long term functional outcome. Screening programs have shown a shift towards more early staged cancers. Patients with early rectal cancer can potentially benefit significantly from rectal preserving therapy. For the earliest stage cancers, local excision is sufficient when the risk of lymph node disease and subsequent recurrence is below 5 %. However, the majority of early cancers are associated with an intermediate risk of lymph node involvement (5–20 %) suggesting that local excision alone is not sufficient, while completion radical surgery, which is currently standard of care, could be a substantial overtreatment for this group of patients. In this multicentre randomised trial, patients with an intermediate risk T1-2 rectal cancer, that has been locally excised using an endoluminal technique, will be randomized between adjuvant chemo-radiotherapylimited to the mesorectum and standard completion total mesorectal excision (TME). To strictly monitor the risk of locoregional recurrence in the experimental arm and enable early salvage surgery, there will be additional follow up with frequent MRI and endoscopy. The primary outcome of the study is three-year local recurrence rate. Secondary outcomes are morbidity, disease free and overall survival, stoma rate, functional outcomes, health related quality of life and costs. The design is a non inferiority study with a total sample size of 302 patients. The results of the TESAR trial will potentially demonstrate that adjuvant chemoradiotherapy is an oncological safe treatment option in patients who are confronted with the difficult clinical dilemma of a radically removed intermediate risk early rectal cancer by polypectomy or transanal surgery that is conventionally treated with subsequent radical surgery. Preserving the rectum using adjuvant radiotherapy is expected to significantly improve morbidity, function and quality of life if compared to completion

    Adjuvant Online (AOL) is web-accessible risk-assessment model that predicts the mortality and the benefits of adjuvant therapy. AOL has never been validated for Asian colon cancer patients. Using the Yonsei Tumor Registry database, patients who were treated within the Yonsei University Health System between 1990 and 2005 for T1-4, N0-2, and M0 colon cancer were included in the calculations for survival. Observed and predicted 5-year overall survival was compared for each patient. The median age of the study population of 1431 patients was 60 years (range, 15–87 years), and the median follow-up duration was 7.9 years (range, 0.06–19.8 years). The predicted 5-year overall survival rate (77.7%) and observed survival (79.5%) was not statistically different (95% Confidential interval, 76.3–81.5) in all patients. Predicted outcomes were within 95% confidential interval of observed survival in both stage II and III disease, including most demographic and pathologic subgroups. Moreover, AOL more accurately predicted OS for patients with stage II than stage III. AOL tended to offer reliable prediction for 5-year overall survival and could be used as a decision making tool for adjuvant treatment in Korean colon cancer patients whose prognosis is similar to other Asian patients

    The pattern of relapse is described in patients with gastric cancer who received adjuvant chemoradiation at the Servicio de Oncologia Medica of Hospital Rafael Angel Calderon Guardia in the period 2006-2010. The evolution of the disease is described. Types of relapse are explained in gastric cancer patients who received chemotherapy-adjuvant radiotherapy. The magnitude of the problem is identified by the calculation of incidence, survival and mortality. Patients with adenocarcinoma type gastric cancer, resected in curative R0 and treated with adjuvant chemotherapy / radiotherapy (QT/RT) were analyzed. The variables of age, sex, functional status (according to ECOG), tumor characteristics, staging (TNM), type of surgery, type of nodal dissection, period between surgery and postoperative therapy were used for a descriptive analysis. Survival analysis is performed using Kaplan - Meier curves from the date of surgery until the date of death or the last control. The online biostat and biomates programs are used to process information. Lymph node dissection has a significant impact on patient survival, as well as the duration of chemotherapy treatment, the presence of positive lymph nodes and other features such as the presence of seal ring cells and lymphovascular invasion. More radical ganglionic dissections and more effective treatments can achieve better results in patient survival [es

    The patient was a 72-year-old man who underwent a low anterior resection for rectal cancer in 2007 (RbRa, pT4a, pN1, cM0, pStage 3a). With the surgically stripped surface testing positive, the pelvic cavity was subjected to 50 Gy of radiation as part of adjuvant radiotherapy. In December 2015, the patient presented with anal pain and bloody stool.A CT scan revealed a pelvic abscess accompanied by gas patterns around the anastomotic site, and a colonoscopy detected formation of a fistula at the anastomotic site. Although CT-guided drainage was performed in response, a new abscess was formed promptly. In April 2016, laparoscopic colostomy with double orifices was performed on the transverse colon. Thereafter the abscesses in the buttocks required four sessions of incision and drainage. The condition improved with no purulent discharge after December 2016. As of 11 months after the colostomy, the pelvic abscess is gradually contracting, though some fistulas have remained. The patient has been followed up on an ambulatory basis.This case is considered to be of an intrapelvic abscess associated with the delayed anastomotic fistula occurred after a lapse of 9 years following irradiation.

    Tumor-released proangiogenic factors suppress endothelial adhesion molecule (EAM) expression and prevent leukocyte extravasation into the tumor. This is one reason why immunotherapy has met with limited success in the clinic. We hypothesized that overcoming EAM suppression with angiogenesis inhibitors would increase leukocyte extravasation and subsequently enhance the effectiveness of cellular immunotherapy. Intravital microscopy, multiple color flow cytometry, immunohistochemistry, and various tumor mouse (normal and T-cell deficient) models were used to investigate the temporal dynamics of cellular and molecular events that occur in the tumor microenvironment during tumor progression and angiostatic intervention. We report that while EAM levels and T-cell infiltration are highly attenuated early on in tumor growth, angiostatic therapy modulates these effects. In tumor models with normal and T-cell-deficient mice, we show the active involvement of the adaptive immune system in cancer and differentiate antiangiogenic effects from antiangiogenic mediated enhancement of immunoextravasation. Our results indicate that a compromised immune response in tumors can be obviated by the use of antiangiogenic agents. Finally, with adoptive transfer studies in mice, we show that a phased combination of angiostatic therapy and T-cell transfer significantly (P response within the tumor microenvironment, in particular as a consequence of the temporal dynamics of EAM levels. Moreover, our results suggest that adjuvant therapy with angiogenesis inhibitors holds promise for cellular immunotherapy in the clinic. ©2011 AACR.

    The treatment of patients with endometrial cancer has been extensively modified in recent years. Several randomized studies have redefined the indications for adjuvant therapy in tumours staged 1. In the absence of poor prognostic factors, the management tends to be less aggressive than before, often limited to vaginal brachytherapy. Conversely, for more advanced lesions, for which prognosis is poor, combinations of chemo-radiation are currently being evaluated. This literature review aims to provide an update on recent developments in the management of adjuvant radiotherapy for endometrial carcinoma. (authors)

    Antiangiogenic tyrosine kinase inhibitors (TKI) that target VEGF receptor-2 (VEGFR2) have not been effective as adjuvant treatments for micrometastatic disease in phase III clinical trials. Angiopoietin-2 (Ang2) is a proangiogenic and proinflammatory vascular destabilizer that cooperates with VEGF. The purpose of this study was to test whether CVX-060 (an Ang2-specific CovX-body) can be combined with VEGFR2-targeting TKIs (sunitinib or regorafenib) to successfully treat postsurgical metastatic disease in multiple orthotopically implanted human tumor xenograft and syngeneic murine tumor models. In the MDA-MB-231.LM2-4 human breast cancer model, adjuvant sunitinib was ineffective, whereas adjuvant CVX-060 delayed the progression of pulmonary or distant lymphatic metastases; however, overall survival was only improved with the adjuvant use of a VEGF-A/Ang2-bispecific CovX-body (CVX-241) but not when CVX-060 is combined with sunitinib. Adjuvant CVX-241 also showed promise in the EMT-6/CDDP murine breast cancer model, with or without an immune checkpoint inhibitor (anti-PD-L1). In the RENCA model of mouse renal cancer, however, combining CVX-060 with sunitinib in the adjuvant setting was superior to CVX-241 as treatment for postsurgical lung metastases. In the HCT116 and HT29 xenograft models of colorectal cancer, both CVX-060 and regorafenib inhibited liver metastases. Overall, our preclinical findings suggest differential strategies by which Ang2 blockers can be successfully combined with VEGF pathway targeting in the adjuvant setting to treat micrometastatic disease-particularly, in combination with VEGF-A blockers (but not VEGFR2 TKIs) in resected breast cancer; in combination with VEGFR2 TKIs in resected kidney cancer; and as single agents or with VEGFR2 TKIs in resected colorectal cancer.

    Purpose: Although chemoradiotherapy was considered the standard adjuvant treatment for gastric cancer, a recent Phase III trial (Medical Research Council Adjuvant Gastric Infusional Chemotherapy [MAGIC]) did not include radiotherapy in the randomization scheme because it was considered expendable. Given radiotherapy's potential, efforts needed to be made to optimize its use for treating gastric cancer. We assessed whether intensity-modulated radiotherapy (IMRT) could improve upon our published results in patients treated with three-dimensional (3D) conformal therapy. Methods and Materials: Fourteen patients with adenocarcinoma of the stomach were treated with adjuvant chemoradiotherapy using a noncoplanar four-field arrangement. Subsequently, a nine-field IMRT plan was designed using a CMS Xio IMRT version 4.3.3 module. Two IMRT beam arrangements were evaluated: beam arrangement 1 consisted of gantry angles of 0 deg., 53 deg., 107 deg., 158 deg., 204 deg., 255 deg., and 306 deg.. Beam arrangement 2 consisted of gantry angles of 30 deg., 90 deg., 315 deg., and 345 deg.; a gantry angle of 320 deg./couch, 30 deg.; and a gantry angle of 35 o /couch, 312 o . Both the target volume coverage and the dose deposition in adjacent critical organs were assessed in the plans. Dose-volume histograms were generated for the clinical target volume, kidneys, spine, and liver. Results: Comparison of the clinical target volumes revealed satisfactory coverage by the 95% isodose envelope using either IMRT or 3D conformal therapy. However, IMRT was only marginally better than 3D conformal therapy at protecting the spine and kidneys from radiation. Conclusions: IMRT confers only a marginal benefit in the adjuvant treatment of gastric cancer and should be used only in the small subset of patients with risk factors for kidney disease or those with a preexisting nephropathy.

    Background and purpose: transoral laser microsurgery (TLM) and adjuvant radiotherapy are an established therapy regimen for locally advanced laryngeal cancer at our institution. Aim of the present study was to assess value of quality of life (QoL) data with special regard to organ function under consideration of treatment efficacy in patients with locally advanced laryngeal cancer treated with larynx-preserving TLM and adjuvant radiotherapy. Patients and methods: from 1994 to 2006, 39 patients (ten UICC stage III, 29 UICC stage IVA/B) with locally advanced laryngeal carcinomas were treated with TLM and adjuvant radiotherapy. Data concerning treatment efficacy, QoL (using the VHI [Voice Handicap Index], the EORTC QLQ-C30 and QLQ-H and N35 questionnaires) and organ function (respiration, deglutition, voice quality) were obtained for ten patients still alive after long-term follow-up. Correlations were determined using the Spearman rank test. Results: after a median follow-up of 80.8 months, the 5-year overall survival rate was 46.8% and the locoregional control rate 76.5%, respectively. The larynx preservation rate was 89.7% for all patients and 100% for patients still alive after follow-up. Despite some verifiable problems in respiration, speech and swallowing, patients showed a subjectively good QoL. Conclusion: TLM and adjuvant radiotherapy is a curative option for patients with locally advanced laryngeal cancer and an alternative to radical surgery. Even if functional deficits are unavoidable in the treatment of locally advanced laryngeal carcinomas, larynx preservation is associated with a subjectively good QoL. (orig.)

    Objectives: Adjuvant radiochemotherapy improves survival of patients with advanced gastric cancer. We assessed in two sequential cohorts whether improved radiotherapy technique (IMRT) together with intensified chemotherapy improves outcome vs. conventional three-dimensional conformal radiotherapy (3D-CRT) and standard chemotherapy in these patients while maintaining or reducing renal toxicity. Materials and Methods: Sixty consecutive patients treated for gastric cancer either with 3D-CRT (n = 27) and IMRT (n = 33) were evaluated. More than 70% had undergone D2 resection. Although there was a slight imbalance in R0 status between cohorts, N+ status was balanced. Chemotherapy consisted predominantly of 5-fluorouracil/folinic acid (n = 36) in the earlier cohort and mostly of oxaliplatin/capecitabine (XELOX, n = 24) in the later cohort. Primary end points were overall survival (OS), disease-free survival (DFS), and renal toxicity based on creatinine levels. Results: Median follow-up (FU) of all patients in the 3D-CRT group was 18 months and in the IMRT group 22 months (median FU of surviving patients 67 months in the 3D-CRT group and 25 months in the IMRT group). Overall median survival (and DFS) were 18 (13) months in the 3D-CRT group and both not reached in the IMRT group (p = 0.0492 and 0.0216). Actuarial 2-year survival was 37% and 67% in the 3D-CRT and IMRT groups, respectively. No late renal toxicity >Grade 2 (LENT-SOMA scale) was observed in either cohort. Conclusion: When comparing sequentially treated patient cohorts with similar characteristics, OS and DFS improved with the use of IMRT and intensified chemotherapy without signs of increased renal toxicity.

    The benefit of adjuvant therapy (AT) for gallbladder cancer (GBC) is unclear as evidenced by conflicting results from nonrandomized studies. Here we aimed to perform a meta-analysis to determine the impact of AT on overall survival (OS). We used data from MEDLINE, EMBASE and the Cochrane Collaboration Library and published between October 1967 and October 2014. Studies that evaluated AT compared with curative-intent surgery alone for resected GBC were included. Subgroup analyses of benefit based on node status, margins status, and American Joint Committee on Cancer (AJCC) staging were prespecified. Data were weighted and pooled using random-effect modeling. Ten retrospective studies involving 3,191 patients were analyzed. There was a nonsignificant improvement in OS with AT compared with surgery alone (hazard ratio [HR], 0.76; 95 % confidence interval [CI], 0.56–1.03). A significant improvement was observed in OS with chemotherapy (CT) compared with surgery alone (HR, 0.42; 95 % CI, 0.22–0.80) by sensitivity analysis. The greatest benefit for AT was also observed in those with R1 disease (HR, 0.33; 95 % CI, 0.19–0.59), LN-positive disease (HR, 0.71; 95 % CI, 0.63–0.81), and AJCC staging meeting or exceeding tumor Stage II (HR, 0.45; 95 % CI, 0.26–0.79), but not in those with LN-negative or R0 disease. Our results strongly support the use of CT as an AT in GBC. Moreover, patients with node positivity, margin positivity, or non-stage I disease are more likely to benefit from AT

    Complementary and alternative medicine (CAM) use has grown considerably, although there is little research on the topic in Spain. The aim of this study was to determine the prevalence of complementary medicine use in adult cancer patients at the same time as they were receiving conventional treatment in a Spanish referral cancer centre. An observational, descriptive, cross-sectional study was conducted in the Ambulatory Treatment Unit during 2 consecutive weeks in March 2015. Adult patients who were receiving intravenous chemotherapy were included. Study variables were obtained from a questionnaire and medical records. 316 patients were included. 32.3% of the patients reported complementary medicine use during this period and 89% were ingesting products by mouth, herbs and natural products being the most commonly used. 81% of patients started to use complementary medicine after diagnosis, and family/friends were the main source of information. 65% of the patients reported improvements, especially in their physical and psychological well-being. Significant predictors of CAM use were female gender (P=0.028), younger age (P<0.001), and secondary education (P=0.009). A large proportion of cancer patients receiving intravenous chemotherapy also use complementary medicine, which they mainly take by mouth. Due to the risk of chemotherapy-CAM interactions, it is important for health-professionals to keep abreast of research on this issue, in order to provide advice on its potential benefit and risks.

    Purpose: Photodynamic therapy (PDT) has shown remarkable activity in a variety of human cancers. In the present study, we report the effects of PDT on inoperable early-stage esophageal cancer. Methods and Materials: Sixty-two patients were treated with an argon dye laser (630 nm wavelength, 300-800 mW of power, energy dose of 200-300 J/cm) after intravenous injection of 5 mg/kg of hematoporphyrin derivative. Eighteen patients (29.5%) had in situ carcinoma (Tis), 30 (48.5%) had T1-stage cancer, 7 (11%) had T2-stage cancer, and 7 (11%) had recurrent disease in the anastomotic area after previous surgery without evidence of invasion outside the lumen. Patients with residual disease after two rounds of PDT received definitive radiotherapy. Patients were evaluated for response to therapy and survival. The follow-up time ranged from 3 to 90 months (median, 32 months). Results: The complete response (CR) rate was 37% (23 of 62) in patients who received PDT alone and 82% (51 of 62) in those who also received radiotherapy. The CR rate after PDT alone was statistically higher (p = 0.04) for patients who had Tis/T1 lesions (21 of 48; 44%) than for those with T2-stage disease (2 of 7; 28%) or recurrent tumors (0 of 7; 0%). Fifty-two percent of patients who had CR following PDT alone did not suffer local tumor recurrence. The median local progression-free survival times after PDT and additional radiotherapy (in cases with incomplete response) was 49 months for Tis- and T1-stage lesions, 30 months for those with T2-stage disease, and 14 months for patients with locally recurrent disease. Patients who completely responded to PDT had a median overall survival (OS) of 50 months, which was significantly longer (p < 0.003) than that of patients not responding to PDT. Toxicity was minimal; we recorded three cases of esophageal stenosis (7%) and one case of tracheo-esophageal fistula (2.5%) after combined PDT and radiotherapy. Conclusion: PDT is an effective regimen for early

    We determined whether adjuvant chemotherapy (AC) would be associated with improved survival after lymph node dissection (LND) for patients with penile cancer (PeCa) who have positive pelvic lymph nodes (PPLNs). We retrospectively identified patients across 4 centers with penile squamous cell carcinoma who underwent LND from 1978 to 2013 and were found to have PPLNs. Patients who received chemotherapy before surgery or in the presence of recurrent disease were excluded. Cox regression was used to evaluate the association of AC with overall survival (OS), which was estimated using the Kaplan-Meier method. Differences in OS were determined with the log-rank test. During the study period, 141 patients who underwent LND for PeCa had PPLNs, and 84 of them met inclusion criteria. Median number of PPLNs was 2 (interquartile range [IQR]: 4-7), with 10% of cases occurring bilaterally and 55% having pelvic extranodal extension. AC was used in 36 (43%) patients. Patients who received AC were younger (P = 0.014), had less-aggressive penile tumor pathology (P<0.01), were less likely to receive adjuvant radiation (P<0.01), had less bilateral inguinal disease (P = 0.019), and had more inguinal extranodal extension (P = 0.042). Median follow-up was 12.1 months. Estimated median OS was 21.7 months (IQR: 11.8-104) in patients who received AC vs. 10.1 (IQR: 5.6-48.1) in those who did not (P = 0.048). AC was independently associated with improved OS on multivariate analysis (hazard ratio: 0.40; 95% CI: 0.19-0.87; P = 0.021). AC is associated with improved OS in patients with PeCa who have PPLNs after LND. Prospective studies are needed to demonstrate causality. Copyright © 2015 Elsevier Inc. All rights reserved.

    Purpose: In a retrospective analysis, adjuvant intensity-modulated radiation therapy (IMRT) combined with modern chemotherapy improved advanced gastric cancer survival rates compared to a combination of three-dimensional conformal radiation therapy (3D-CRT) and conventional chemotherapy. We report on the long-term outcomes of two consecutive patient cohorts that were treated with either IMRT and intensive chemotherapy, or 3D-CRT and conventional chemotherapy. Patients and methods: Between 2001 and 2008, 65 consecutive gastric cancer patients received either 3D-CRT (n = 27) or IMRT (n = 38) following tumor resection. Chemotherapy comprised predominantly 5-fluorouracil/folinic acid (5-FU/FA) in the earlier cohort and capecitabine plus oxaliplatin (XELOX) in the latter. The primary endpoints were overall survival (OS) and disease-free survival (DFS). Results: Median OS times were 18 and 43 months in the 3D-CRT and IMRT groups, respectively (p = 0.0602). Actuarial 5-year OS rates were 26 and 47 %, respectively. Within the IMRT group, XELOX gave better results than 5-FU/FA in terms of OS, but this difference was not statistically significant. The primary cause of death in both groups was distant metastasis. Median DFS times were 14 and 35 months in the 3D-CRT and IMRT groups, respectively (p = 0.0693). Actuarial 5-year DFS rates were 22 and 44 %, respectively. Among patients receiving 5-FU/FA, DFS tended to be better in the IMRT group, but this was not statistically significant. A similar analysis for the XELOX group was not possible as 3D-CRT was almost never used to treat these patients. No late toxicity exceeding grade 3 or secondary tumors were observed. Conclusion: After a median follow-up period of over 5 years, OS and DFS were improved in the IMRT/XELOX treated patients compared to the 3D-CRT/5-FU/FA group. Long-term observation revealed no clinical indications of therapy-induced secondary tumors or renal toxicity. (orig.)

    Treatment of endometrial carcinoma in the adjuvant setting includes in most cases vaginal brachytherapy. In our institution, we use the customized vaginal mold technique. Herein, we report the advantages of this personalized applicator in terms of target coverage, normal tissue preservation, the incidence of air pockets, and its potential impact on dosimetry. A total of 15 patients receiving postoperative vaginal cuff high-dose-rate brachytherapy with the mold applicator technique were enrolled in this prospective data collection study. Patients were treated with either two or four fractions of 5 Gy prescribed to the clinical target volume, which consisted of an irradiation of the vaginal cuff and the upper third of the vagina. Target coverage; dose to organs at risk, in addition to the volume; and the dosimetric impact of air pockets surrounding the mold were evaluated. In 15 patients, a total of 27 air pockets were identified. The average number of air pockets per patient was 1.8 (range, 0-4), with the average total air pocket volume being 0.1 cc (range, 0.01-0.54). The average dose reduction at 5mm from the air pocket was 26% (range, 6-45%). The minimal clinical target volume coverage reported was 95% and the maximal dose received by 2 cc of the bladder, rectum, and sigmoid never exceeded 110% of the prescribed dose. Vaginal cuff high-dose-rate brachytherapy using the molded applicator provides personalized tailored treatment in terms of anatomical conformity. This translates into a dosimetrical advantage with smaller and fewer air pockets than reported in the literature with the use of cylinders. Copyright © 2015 American Brachytherapy Society.

    Monoclonal antibodies (mAb), such as trastuzumab are a valuable addition to breast cancer therapy. Data obtained from neoadjuvant settings revealed that antibody-dependent cell-mediated cytotoxicity (ADCC) is a major mechanism of action for the mAb trastuzumab. Conflicting results still call into question whether disease progression, prolonged treatment or concomitant chemotherapy influences ADCC and related immunological phenomena. We analyzed the activity of ADCC and antibody-dependent cell-mediated phagocytosis (ADCP) of peripheral blood mononuclear cells (PBMCs) from human epidermal growth factor receptor 2 (HER2/neu) positive breast cancer patients receiving trastuzumab therapy either in an adjuvant (n = 13) or metastatic (n = 15) setting as well as from trastuzumab treatment-naive (t-naive) HER2/neu negative patients (n = 15). PBMCs from healthy volunteers (n = 24) were used as controls. ADCC and ADCP activity was correlated with the expression of antibody binding Fc-gamma receptor (FcγR)I (CD64), FcγRII (CD32) and FcγRIII (CD16) on CD14+ (monocytes) and CD56+ (NK) cells, as well as the expression of CD107a+ (LAMP-1) on CD56+ cells and the total amount of CD4+CD25+FOXP3+ (Treg) cells. In metastatic patients, markers were correlated with progression-free survival (PFS). ADCC activity was significantly down regulated in metastatic, adjuvant and t-naive patient cohorts as compared to healthy controls. Reduced ADCC activity was inversely correlated with the expression of CD107a on CD56+ cells in adjuvant patients. ADCC and ADCP activity of the patient cohorts were similar, regardless of treatment duration or additional chemotherapy. PFS in metastatic patients inversely correlated with the number of peripheral Treg cells. The reduction of ADCC in patients as compared to healthy controls calls for adjuvant strategies, such as immune-enhancing agents, to improve the activity of trastuzumab. However, efficacy of trastuzumab-specific ADCC and ADCP appears not to

    This article aims to review the risk stratification of endometrial cancer, treatment rationale, outcomes, treatment planning, and treatment recommendations of vaginal brachytherapy (VBT) in the postoperative management of endometrial cancer patients. The authors performed a thorough review of the literature and reference pertinent articles pertaining to the aims of this review. Adjuvant VBT for early-stage endometrial cancer patients results in very low rates of vaginal recurrence (0-3.1%) with low rates of late toxicity which are primarily vaginal in nature. Post-Operative Radiation Therapy in Endometrial Cancer 2 (PORTEC-2) supports that VBT results in noninferior rates of vaginal recurrence compared to external beam radiotherapy for the treatment of high-intermediate risk patients. VBT as a boost after external beam radiotherapy, in combination with chemotherapy, and for high-risk histologies have shown excellent results as well though randomized data do not exist supporting VBT boost. There are many different applicators, dose-fractionation schedules, and treatment planning techniques which all result in favorable clinical outcomes and low rates of toxicity. Recommendations have been published by the American Brachytherapy Society and the American Society of Radiation Oncology to help guide practitioners in the use of VBT. Data support that patients and physicians prefer joint decision making regarding the use of VBT, and patients often desire additional treatment for a marginal benefit in risk of recurrence. Discussions regarding adjuvant therapy for endometrial cancer are best performed in a multidisciplinary setting, and patients should be counseled properly regarding the risks and benefits of adjuvant therapy.

    Summary Background Incorporation of a taxane as adjuvant treatment for early breast cancer offers potential for further improvement of anthracycline-based treatment. The UK TACT study (CRUK01/001) investigated whether sequential docetaxel after anthracycline chemotherapy would improve patient outcome compared with standard chemotherapy of similar duration. Methods In this multicentre, open-label, phase III, randomised controlled trial, 4162 women (aged >18 years) with node-positive or high-risk node-negative operable early breast cancer were randomly assigned by computer-generated permuted block randomisation to receive FEC (fluorouracil 600 mg/m2, epirubicin 60 mg/m2, cyclophosphamide 600 mg/m2 at 3-weekly intervals) for four cycles followed by docetaxel (100 mg/m2 at 3-weekly intervals) for four cycles (n=2073) or control (n=2089). For the control regimen, centres chose either FEC for eight cycles (n=1265) or epirubicin (100 mg/m2 at 3-weekly intervals) for four cycles followed by CMF (cyclophosphamide 600 mg/m2, methotrexate 40 mg/m2, and fluorouracil 600 mg/m2 at 4-weekly intervals) for four cycles (n=824). The primary endpoint was disease-free survival. Analysis was by intention to treat (ITT). This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN79718493. Findings All randomised patients were included in the ITT population. With a median follow-up of 62 months, disease-free survival events were seen in 517 of 2073 patients in the experimental group compared with 539 of 2089 controls (hazard ratio [HR] 0·95, 95% CI 0·85–1·08; p=0·44). 75·6% (95% CI 73·7–77·5) of patients in the experimental group and 74·3% (72·3–76·2) of controls were alive and disease-free at 5 years. The proportion of patients who reported any acute grade 3 or 4 adverse event was significantly greater in the experimental group than in the control group (p<0·0001); the most frequent events were neutropenia (937 events vs 797 events

    The aim of this cross-sectional health care study (use of bisphosphonates in primary tumors of the mammae, EBisMa) is to determine how often bisphosphonate medication is used in patients with non-metastatic primary breast cancer treatment, but who do not suffer from osteoporosis. Furthermore, we describe patients' characteristics and the most frequently used type of bisphosphonate in adjuvant therapy. The study population included primary breast cancer patients of four breast centers in northern Germany. Data on bisphosphonate therapy were collected by use of patient questionnaires; clinical data were extracted from the registers. Patients with and without prescribed bisphosphonate adjuvant treatment were tested for statistically significant differences regarding their characteristics. Four hundred seventy-four of 663 contacted patients participated in the study. Thirty-nine out of 474 patients (9.6%) were on adjuvant bisphosphonate therapy. Zoledronic acid was the most frequently reported bisphosphonate used for prevention of bone metastases. Compared to patients who did not report bisphosphonate medication, women who did report bisphosphonate therapy had a significantly higher advanced tumor stage (p Bisphosphonates are rarely used in the adjuvant treatment of primary breast cancer. Patients with advanced tumor stage were more likely to use bisphosphonates in the adjuvant treatment of primary breast cancer. Further research is needed to identify patients who may benefit most from adjuvant bisphosphonate treatment.

    2017-09-01

    The role of ovarian function suppression (OFS) through luteinizing hormone-releasing hormone agonists (LHRHa) in addition to tamoxifen has been questioned until recently. In 2015, two large clinical trials led to a paradigm shift in the adjuvant endocrine treatment of premenopausal women, introducing the use of LHRHa plus tamoxifen (or aromatase inhibitor, AI) into current clinical practice. Areas covered: The present review aims to provide an in-depth overview of the role of LHRHa+tamoxifen for the adjuvant treatment of premenopausal women with hormone receptor positive breast cancer (HR+BC). Expert opinion: The addition of LHRHa to endocrine treatment (either tamoxifen or AI) is effective in premenopausal women who are at high risk of relapse. To date, no clear recommendations are available for the choice between LHRHa+tamoxifen and LHRH+AI. Although recent data showed better DFS with LHRHa+AI, other issues should be considered: 1) approximately 20 out of 100 women do not reach complete OFS with LHRHa+AI; 2) there is no extended endocrine therapy option that can be applied to women who received 5 years of LHRHa+AI and remained premenopausal at the end of the fifth year. Long-term results of the SOFT-TEXT study are needed to establish if LHRHa+AI is superior to LHRHa+tamoxifen.

    The current standard of adjuvant treatment for gastric cancer after curative resection is concurrent administration of radiotherapy and 5-fluorouracil-based chemotherapy. The radiation fields are often arranged as anterioposterior-posteroanterior opposed parallel fields with general recommendations for sparing at least two-thirds of one kidney. We investigated whether a better radiation distribution would be achievable with three-dimensional conformal approaches compared with the classic anterioposterior-posteroanterior fields. A total of 19 patients with adenocarcinoma of the stomach were treated with adjuvant chemoradiotherapy using a non-coplanar four-field arrangement. In each case, parallel planning using an anterioposterior-posteroanterior arrangement and a four-field "box" was performed, and the generated plans were subsequently compared for coverage of target volumes and doses to irradiated organs next to the tumor bed. A separate analysis was performed for kidneys exposed to greater and lower doses in each patient. The mean radiation dose and percentage of kidney volume receiving a dose >20 Gy were registered. Statistical analysis was performed using the two-tailed t test. The clinical target volume was adequately covered in all three plans. In the greater-dose kidney group, all the differences were statistically significant with a benefit for the three-dimensional plan. In the lower-dose kidney group, the differences in the mean radiation dose did not reach the level of statistical significance, and the differences in the kidney volume receiving a dose >20 Gy showed a statistically significant benefit for the three-dimensional plan. Non-coplanar three-dimensional-based conformal planning for postoperative radiotherapy for gastric cancer provided the best results regarding kidney and spinal cord exposure with adequate clinical target volume coverage. This technique was readily implemented in clinical practice.

    Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

    Lung cancer and cervical cancer are higher in incidence for Indigenous Australians and survival is worse compared with non-Indigenous Australians. Here we aim to determine if being Indigenous and/or other factors are associated with patients receiving "suboptimal treatment" compared to "optimal treatment" according to clinical guidelines for two cancer types. Data were collected from hospital medical records for Indigenous adults diagnosed with cervical cancer and non-small cell lung cancer (NSCLC) and a frequency-matched comparison group of non-Indigenous patients in the Queensland Cancer Registry between January 1998 and December 2004. The two cancer types were analyzed separately. A total of 105 women with cervical cancer were included in the study, 56 of whom were Indigenous. Indigenous women had higher odds of not receiving optimal treatment according to clinical guidelines (unadjusted OR 7.1; 95% CI, 1.5-33.3), even after adjusting for stage (OR 5.7; 95% CI, 1.2-27.3). Of 225 patients with NSCLC, 198 patients (56% Indigenous) had sufficient information available to be analyzed. The odds of receiving suboptimal treatment were significantly higher for Indigenous compared to non-Indigenous NSCLC patients (unadjusted OR 1.9; 95% CI, 1.0-3.6) and remained significant after adjusting for stage, comorbidity and age (adjusted OR 2.1; 95% CI, 1.1-4.1). The monitoring of treatment patterns and appraisal against guidelines can provide valuable evidence of inequity in cancer treatment. We found that Indigenous people with lung cancer or cervical cancer received suboptimal treatment, reinforcing the need for urgent action to reduce the impact of these two cancer types on Indigenous people. © 2016 John Wiley & Sons Australia, Ltd.

    Purpose: To analyze the outcome of adjuvant chemoradiotherapy for patients with distal common bile duct (CBD) cancer who underwent curative surgery, and to identify the prognostic factors for these patients. Methods and Materials: Between January 1991 and December 2002, 38 patients with adenocarcinoma of the distal CBD underwent curative resection followed by adjuvant chemoradiotherapy. There were 27 men and 11 women, and the median age was 60 years (range, 34-73). Adjuvant radiotherapy was delivered to the tumor bed and regional lymph nodes up to 40 Gy at 2 Gy/fraction with a 2-week planned rest. Intravenous 5-fluorouracil (500mg/m 2 /day) was given on day 1 to day 3 of each split course. The median follow-up period was 39 months. Results: The 5-year overall survival rate of all patients was 49.1%. On univariate analysis, only histologic differentiation (p = 0.0005) was associated with overall survival. Tumor size (≤2cm vs. >2cm) had a marginally significant impact on the treatment outcome (p = 0.0624). However, there was no difference in overall survival rates between T3 and T4 tumors (p = 0.6189), for which the main determinants were pancreatic and duodenal invasion, respectively. On multivariate analysis, histologic differentiation (p = 0.0092) and tumor size (p = 0.0046) were independent risk factors for overall survival. Conclusions: Long-term survival can be expected in patients with distal CBD cancer undergoing curative surgery and adjuvant chemoradiotherapy. Histologic differentiation and tumor size were significant prognostic factors predicting overall survival, whereas duodenal invasion was not. This finding suggests the need for further refinement in tumor staging.

    Full Text Available OBJECTIVES: to identify the prevalence, and describe the management of, neutropenia throughout the chemotherapy treatment among women with breast cancer.METHODS: observational study, cycles of chemotherapy. 116 neutropenic events were recorded, and 63.3% of the patients presented neutropenia at some point of their treatment, 46.5% of these presenting grade II. The management used was temporary suspension between the cycles and the mean number of delays was 6 days. The study was prospective and longitudinal, where the evaluation of the hematological toxicities was undertaken at each cycle of chemotherapy, whether neoadjuvant or adjuvant.RESULTS: 79 women were included, who received 572 cycles. However, the reasons for the suspensions were the lack of a space in the chemotherapy center, followed by neutropenia.CONCLUSION: neutropenia is one of the most common and serious adverse events observed during the chemotherapy. Nursing must invest in research regarding this adverse event and in management strategies for organizing the public health system, so as to offer quality care.

    Background and Purpose: Locoregional relapse is a problem frequently encountered with advanced gastric cancer. Data from the randomized Intergroup trial 116 suggest effectiveness of adjuvant radiochemotherapy, albeit with significant toxicity. The potential of intensity-modulated radiotherapy (IMRT) to reduce toxicity by significantly reducing maximum and median doses to organs at risk while still applying sufficient dose to the target volume in the upper abdomen was studied. Patient and Methods: For a typical configuration of target volumes and organs, a step-and-shoot IMRT plan (eight beam orientations), developed as a class solution for treatment of tumors in the upper abdomen (Figures 1 to 3), a conventional plan, a combination of the conventional plan with a kidney-sparing boost plan, and a conventional plan with noncoplanar ap and pa fields for improved kidney sparing were compared with respect to coverage of target volume and dose to organs at risk with a dose of 45 Gy delivered as the median dose to the target volume. Results: When using the conventional three-dimensionally planned box techniques, the right kidney could be kept below tolerance, but median dose to the left kidney amounted to between 14.8 and 26.9 Gy, depending on the plan. IMRT reduced the median dose to the left kidney to 10.5 Gy, while still keeping the dose to the right kidney 90% of prescription dose were delivered to > 90% of target volume with IMRT (Table 1). Conclusion: IMRT has the potential to deliver efficient doses to target volumes in the upper abdomen, while delivering dose to organs at risk in a more advantageous fashion than a conventional technique. For clinical implementation, the possibility of extensive organ motion in the upper abdomen has to be taken into account for treatment planning and patient positioning. The multitude of potential risks related to its application has to be the subject of thorough follow-up and further studies. (orig.)

    Chemotherapy damages the bone marrow and that is one of the most important problems in the treatment of malignancies, particularly colorectal cancer. The aim of the present study was to assess the effects of surgical adjuvant chemotherapy for CRC patients on human MSCs using an in vitro culture system. The bone marrows of 43 CRC patients were harvested for separation and culture of MSC at pre- and post-chemotherapy. The number of colonies forming unit-fibroblast (CFU-F) was counted. The adhesive function of MSC was assayed and the growth of colony-forming unit-mixed hematopoietic cell (CFU-Mix) on the MSC layer was observed. The concentration of IL-6, SCF and FLT-T3 proteins in the MSC culture supernatant were also detected by ELISA assay. In the CRC patients with chemotherapy, we have demonstrated that the CFU-F exhibit significantly decreased. We also showed that the adhesive rate of bone marrow mesenchymal stem cell (BMSC) was significantly decreased. The growth of CFU-Mix on the MSC layer was inhibited. Most importantly, decreased CFU-F and the adhesive rate of BMSC were correlated significantly with decreased interleukins and stem-cell factor (IL-6, SCF and FLT-3L) expressions in the CRC patients after chemotherapy. Our results suggest that MSCs of CRC patients can be damaged by chemotherapy. Our data also indicates that the decreased expression of haematogenesis factors may play an important role in the pathogenesis. In the future, the MSC refused may have a potential clinical application in chemotherapeutically treated patients.

Evidence is accumulating on the role of polymorphic genetic variants, such as single nucleotide polymorphisms (SNPs that could influence normal tissue response after radiation. The most studied SNPs include those in genes involved in DNA repair (single- and double-strand breaks, and base excision and those active in the response to oxidative stress.Case report: We present the case report of a 60-year-old woman with early breast cancer who underwent adjuvant hormone therapy and conventional radiotherapy, and subsequently developed unacceptable cosmetic toxicities of the irradiated breast requiring a genetic test of genes involved in DNA repair mechanisms. The patient was found to be heterozygous for G28152A (T/C and C18067T (A/G mutations in X-ray repair cross-complementing group 1 (XRCC1 and 3 (XRCC3, respectively, homozygous for A313G (G/G mutation in glutathione S transferase Pi 1 (GSTP1, and wild-type for A4541G (A/A in XRCC3 and G135C (G/G in RAD51 recombinase.Conclusion: The role of SNPs should be taken into account when a severe phenomenon appears in normal tissues after radiation treatment, because understanding the molecular basis of individual radiosensitivity may be useful for identifying moderately or extremely radiosensitive patients who may need tailored therapeutic strategies.

    Colorectal cancer is the third leading cause of cancer-associated mortality in the western world. The ability to predict a patient's response to chemotherapy may be of great value for clinicians and patients when planning cancer treatment. The aim of the current study was to develop a urine metabolomics-based biomarker panel to predict adverse events and response to chemotherapy in patients with colorectal cancer. A retrospective chart review of patients diagnosed with stage III or IV colorectal cancer between 2008 and 2012 was performed. The exclusion criteria included chemotherapy for palliation and patients living outside of Alberta. Data was collected concerning the chemotherapy regimen, adverse events associated with chemotherapy, disease progression and recurrence and 5-year survival. Adverse events were subdivided as follows: Delays in treatment, dose reductions, hospitalizations and chemotherapy regime changes. Patients provided urine samples for analysis prior to any intervention. Nuclear magnetic resonance (NMR) spectra of urine samples were acquired. The 1H NMR spectrum of each urine sample was analyzed using Chenomx NMRSuite v7.0. Using machine learning, predictors were generated and evaluated using 10-fold cross-validation. Urine spectra were obtained for 62 patients. The best predictors resulted in area under the receiver operating characteristic curve values of: 0.542 for chemotherapy dose reduction, 0.612 for 5-year survival, 0.650 for cancer recurrence and 0.750 for treatment delay. Therefore, predictors were developed for response to and adverse events from chemotherapy for patients with colorectal cancer patients. The predictor for treatment delay has the most promise, and further studies will aid its refinement and improvement of its accuracy. PMID:29142749

    To evaluate the side effects, pattern of failure, and survival rate according to the sequence of postoperative adjuvant radiotherapy and chemotherapy, patients with stages II and III rectal cancer who had undergone curative resection were randomized to early radiotherapy group(am II), then we intend to determine the most effective sequence of the radiotherapy and chemotherapy. From January 1996 to March 1999, 313 patients with curatively resected stages II and III rectal cancer have been randomized to 'early' or 'late' radiation therapy group and received combined chemotherapy (5-FU 375 mg/m{sup 2}, IV bolus daily D1-5, 8 cycles) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Arm I received radiation therapy from day 1 with first cycle of chemotherapy and arm II received radiation therapy from day 57 with third cycle of chemotherapy after completion of first two cycles. Preliminary analysis was performed with 228 patients registered up to Jun 1998. Two out of the 228 patients were excluded because of double primary cancer. Median follow-up period was 23 months. Local recurrence occurred in 11 patients (9.7%) for arm l and 9 patients (8%) for arm II. There was no significant difference between both groups (p=0.64). However, distant metastasis was found in 22 patients (19.5%) for arm l and 35 patients (31.0%) for arm II and which showed statistically significant difference between the two groups (p=0.046). And neither 3-year disease-free survival (70.2% vs 59.2%, p=0.2) nor overall survival (89.4% vs 88.0%, p=0.47) showed significant differences. The incidence of leukopenia during radiation therapy and chemotherapy was 78.3% and 79.9% respectively but leukopenia more than RTOG grade 3 was only 2.1% and 6.0% respectively. The incidence of diarrhea more than 10 times per day was significantly higher in the patients for arm k than for arm II (71.2% vs 41.6%, p=0.02) but this complication was controlled with supportive cares

    Background Lapatinib (L) plus trastuzumab (T) improves outcomes for metastatic human epidermal growth factor 2–positive breast cancer and increases the pathologic complete response in the neoadjuvant setting, but their role as adjuvant therapy remains uncertain. Methods In the Adjuvant Lapatinib and/or Trastuzumab Treatment Optimization trial, patients with centrally confirmed human epidermal growth factor 2–positive early breast cancer were randomly assigned to 1 year of adjuvant therapy with T, L, their sequence (T→L), or their combination (L+T). The primary end point was disease-free survival (DFS), with 850 events required for 80% power to detect a hazard ratio (HR) of 0.8 for L+T versus T. Results Between June 2007 and July 2011, 8,381 patients were enrolled. In 2011, due to futility to demonstrate noninferiority of L versus T, the L arm was closed, and patients free of disease were offered adjuvant T. A protocol modification required P ≤ .025 for the two remaining pairwise comparisons. At a protocol-specified analysis with a median follow-up of 4.5 years, a 16% reduction in the DFS hazard rate was observed with L+T compared with T (555 DFS events; HR, 0.84; 97.5% CI, 0.70 to 1.02; P = .048), and a 4% reduction was observed with T→L compared with T (HR, 0.96; 97.5% CI, 0.80 to 1.15; P = .61). L-treated patients experienced more diarrhea, cutaneous rash, and hepatic toxicity compared with T-treated patients. The incidence of cardiac toxicity was low in all treatment arms. Conclusion Adjuvant treatment that includes L did not significantly improve DFS compared with T alone and added toxicity. One year of adjuvant T remains standard of care. PMID:26598744

    Purpose: The optimal adjuvant radiation treatment for endometrial carcinoma (EC) remains controversial. Adjuvant vaginal cuff brachytherapy (VB) has emerged as an increasingly common treatment modality. However, the time trends for using VB, external beam radiation therapy (EBRT), or combined therapy (VB+EBRT) have not been well characterized. We therefore examined the utilization trends of VB, EBRT, and VB+EBRT for adjuvant RT in International Federation of Gynecologic Oncology (FIGO) stage I and II EC over time. Methods and Materials: We evaluated treatment patterns for 48,122 patients with EC diagnosed between January 1995 and December 2005, using the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) public use database. Chi-squared tests were used to assess differences by radiation type (VB, EBRT, and VB+EBRT) and various demographic and clinical variables. Results: Analyses were limited to 9,815 patients (20.4%) with EC who met the inclusion criteria. Among women who received adjuvant RT, the proportion receiving VB increased yearly (12.9% in 1995 compared to 32.8% in 2005 (p < 0.0001). The increasing use of VB was proportional to the decreasing use of EBRT (56.1% in 1995 to 45.8% in 2005; p < 0.0001) and VB+EBRT (31.0% in 1995 to 21.4% in 2005; p < 0.001). Conclusions: This population-based report demonstrates an increasing trend in the use of VB in the adjuvant setting after hysterectomy for treatment of women with FIGO stage I-II EC. VB alone appears to be replacing pelvic EBRT and VB+EBRT therapy in the management of stage I-II EC.

We describe the association of single-nucleotide polymorphisms (SNP) in candidate genes with lipid profiles in women treated with adjuvant aromatase inhibitors. We conducted a prospective observational study to test the associations between SNPs in candidate genes in estrogen signaling and aromatase inhibitor metabolism pathways with fasting lipid profiles during the first 3 months of aromatase inhibitor therapy in postmenopausal women with early breast cancer randomized to adjuvant letrozole or exemestane. We performed genetic association analysis and multivariable linear regressions using dominant, recessive, and additive models. A total of 303 women had complete genetic and lipid data and were evaluable for analysis. In letrozole-treated patients, SNPs in CYP19A1, including rs4646, rs10046, rs700518, rs749292, rs2289106, rs3759811, and rs4775936 were significantly associated with decreases in triglycerides by 20.2 mg/dL and 39.3 mg/dL (P < 0.00053), respectively, and with variable changes in high-density lipoprotein (HDL-C) from decreases by 4.2 mg/dL to increases by 9.8 mg/dL (P < 0.00053). Variants in CYP19A1 are associated with decreases in triglycerides and variable changes in HDL-C in postmenopausal women on adjuvant aromatase inhibitors. Future studies are needed to validate these findings, and to identify breast cancer survivors who are at higher risk for cardiovascular disease with aromatase inhibitor therapy. ©2015 American Association for Cancer Research.

    This study aimed to (1) identify subgroups of cancer patients with distinct personal control trajectories during psychological care, (2) examine whether socio-demographic, clinical, and psychological care characteristics could distinguish trajectories, and (3) examine differential patterns of psychological symptoms between trajectories. This naturalistic study focused on 241 cancer patients receiving psychological care at psycho-oncology institutions. Data were collected before the initiation of psychological care, and 3 and 9 months thereafter. Latent class growth analysis was applied to identify personal control trajectories. Three personal control trajectories were identified: enduring improvement (41%), temporary improvement (50%), and deterioration (9%). Education and baseline physical symptoms distinguished these trajectories. In the whole group, improvements in personal control were associated with improvements in psychological symptoms. Patients at distinct trajectories reported different levels of psychological symptoms, but did not differ in their courses of psychological symptoms. Patients in the enduring and temporary control improvement groups experienced significant psychological symptoms reductions over time, whereas patients in the control deterioration group maintained high psychological symptoms. Improvements in personal control seem to depend on initial control level: those who start with the highest control levels show subsequent improvements, whereas those with the lowest control levels show subsequent deterioration.

    Studies show adjuvant endocrine therapy increases survival and decreases risk of breast cancer recurrence for hormone receptor-positive tumors. Yet studies also suggest that adherence rates among women taking this therapy may be as low as 50% owing largely to adverse side effects. Despite these rates, research on longitudinal patient decision making regarding this therapy is scant. We sought to map the decision-making process for women considering and initiating adjuvant endocrine therapy, paying particular attention to patterns of uncertainty and decisional change over time. A longitudinal series of semistructured interviews conducted at a multispecialty health care organization in Northern California with 35 newly diagnosed patients eligible for adjuvant endocrine therapy were analyzed. Analysis led to the identification and indexing of 3 new decision-making constructs-decisional phase, decisional direction, and decisional resolve-which were then organized using a visual matrix and examined for patterns characterizing the decision-making process. Our data reveal that most patients do not make a single, discrete decision to take or not take hormone therapy but rather traverse multiple decisional states, characterized by 1) phase, 2) direction, and 3) strength of resolve. Our analysis tracks these decisional states longitudinally using a grayscale-coded matrix. Our data show that decisional resolve wavers not just when considering therapy, as the existing concept of decisional conflict suggests, but even after initiating it, which may signal future decisions to forgo therapy. Adjuvant endocrine therapy, like other chronic care decisions, has a longer decision-making process and implementation period. Thus, theoretical, empirical, and clinical approaches should consider further exploring the new concept and measurement of decisional resolve, as it may help to improve subsequent medication adherence. © The Author(s) 2016.

    Gastric cancer (GC) has a high morbidity worldwide each year especially in China and advanced GC is well known with poor prognosis, for which surgical resection combine adjuvant chemotherapy is the optimal choice for therapy. Leukocyte is an important index during the treatment for its influence on drugs' dosage and tolerance. Therefore, peripheral blood leukocyte and its subsets during adjuvant chemotherapy may have great clinical value for predicting prognostic. In this retrospective study, we showed the distribution of white blood cell and its subsets in the baseline period before adjuvant chemotherapy in 399 patients who underwent radical resection for advanced GC from January 1, 2008 to August 31, 2012. We investigated the relationship between leukocyte count and overall survival (OS) as well as disease-free survival (DFS). In these patients, females were more likely to have less white blood cells after operation (P=0.016). Patients with pre-chemotherapy leukocyte count less than 4×10(9)/L got worse DFS (P=0.028) and OS (P=0.016). In multivariate analysis, tumor size ≥ 6cm (P=0.033), TNM stage IV (P=0.024), vascular or nerval invasion (P=0.005) and leukocyte count less than 4.0×10(9)/L (P=0.019) was associated with poor DFS. TNM stage IV (P=0.008), vascular or nerval invasion (P=0.001) and lower leukocyte count (P=0.045) were independent risk factors for poor OS. Taken together, our findings suggest that pre-adjuvant chemotherapy peripheral blood leukocyte count correlates with clinical outcome of patients with advanced GC after radical resection.

    The epirubicin with cisplatin and infusional 5-fluorouracil (5-FU) (ECisF) regimen was found to be highly active in the treatment of metastatic breast cancer and as neoadjuvant therapy. The UK TRAFIC (trial of adjuvant 5-FU infusional chemotherapy) trial (CRUK/95/007) compared this schedule with 5-FU, epirubicin and cyclophosphamide (FEC60) as adjuvant therapy in patients with early breast cancer. In this multicentre, open-label, phase III randomised controlled trial, 349 women were randomly assigned to receive i.v. ECisF [epirubicin 60 mg/m(2), day 1, cisplatin 60 mg/m(2), day 1 and 5-FU 200 mg/m(2) by daily 24-h infusion (n = 172)] or FEC [5-FU 600 mg/m(2), day 1, epirubicin 60 mg/m(2), day 1 and cyclophosphamide 600 mg/m(2), day 1 (n = 177)]. Both treatments were delivered every 3 weeks for six cycles. The primary end point was relapse-free interval (RFI). TRAFIC is registered as an International Standard Randomised Controlled Trial (ISRCTN 83324925). All randomised patients were included in the intent-to-treat population. With a median follow-up of 112 months, there was no significant difference in RFI between the treatment groups [hazard ratio 0.84 (95% confidence interval 0.60-1.19); P = 0.33]. Toxic effects were more frequent in patients allocated to ECisF. While limited by size, TRAFIC has long follow-up. No evidence of a clinically worthwhile benefit for the infusional treatment compared with standard treatment was observed which would justify further investigation or widespread use.

    The investigational arm of INT0116, a fluorouracil (FU) and leucovorin-containing chemoradiotherapy regimen, is a standard treatment for patients with resected gastric cancer with a 2-year disease-free survival rate (DFS) of 52%. Toxicity is also significant. More beneficial and safer regimens are needed. We performed a randomized phase II study among 39 cancer centers to evaluate two paclitaxel and cisplatin-containing regimens, one with FU (PCF) and the other without (PC) in patients with resected gastric cancer. Patients received two cycles of postoperative chemotherapy followed by 45 Gy of radiation with either concurrent FU and paclitaxel or paclitaxel and cisplatin. The primary objective was to show an improvement in 2-year DFS to 67% as compared with INT 0116. From May 2001 to February 2004 (study closure), 78 patients entered this study, and 73 were evaluable. At the planned interim analysis of 22 patients on PCF, grade 3 or higher GI toxicity was 59%. This was significantly worse than INT0116, and this arm was closed. Accrual continued on PC. The median DFS was 14.6 months for PCF and has not been reached for PC. For PC the 2-year DFS is 52% (95% CI, 36% to 68%). Though PC appears to be safe and the median DFS favorable, the DFS failed to exceed the lower bound of 52.9% for the targeted 67% DFS at 2 years and can not be recommended as the adjuvant arm for future randomized trials.

    The role of adjuvant bisphosphonates in early breast cancer is uncertain. We therefore did a large randomised trial to investigate the effect of the adjuvant use of zoledronic acid on disease-free survival (DFS) in high-risk patients with early breast cancer. In the AZURE trial, an open-label, international, multicentre, randomised, controlled, parallel-group phase 3 trial, women (age ≥18 years) with stage II or III breast cancer were randomly assigned (1:1) by a central automated 24-h computer-generated telephone minimisation system (balanced for number of involved axillary lymph nodes, tumour stage, oestrogen receptor status, type and timing of systemic therapy, menopausal status, statin use, and treatment centre) to receive standard adjuvant systemic treatment alone (control group) or with 4 mg intravenous zoledronic acid every 3-4 weeks for six doses, then every 3 months for eight doses, followed by every 6 months for five doses, for a total of 5 years of treatment. The primary endpoint was disease-free survival (DFS). Secondary endpoints were invasive DFS (IDFS), overall survival, time to bone metastases, time to distant recurrence, and subgroup analyses of variables included in the randomisation. All patients have completed study treatment. Results from the intention-to-treat final analysis of this fully recruited study are presented after a median follow-up of 84 months (IQR 66-93). This final efficacy analysis was planned to take place after 940 DFS events. This trial is registered with ClinicalTrials.gov, NCT00072020. 3360 women were recruited from 174 centres in seven countries between Sept 4, 2003, and Feb 16, 2006. The number of DFS events did not differ between groups: 493 in the control group and 473 in the zoledronic acid group (adjusted hazard ratio [HR] 0·94, 95% CI 0·82-1·06; p=0·30). IDFS (HR 0·93, 95% CI 0·82-1·05; p=0·22), overall survival (0·93, 0·81-1·08; p=0·37), and distant recurrences (0·93, 0·81-1·07; p=0·29) were much

    Purpose The aim of the present study was to evaluate the effectiveness of hyaluronic acid (HA) in the prevention of acute and late vaginal toxicities after high-dose-rate (HDR) vaginal brachytherapy (BT). Material and methods Between January 2011 and January 2015, we retrospectively analyzed 126 patients with endometrial cancer who underwent extrafascial hysterectomy with or without lymphadenectomy and adjuvant HDR-vaginal BT +/– adjuvant chemotherapy. The total dose prescription was 21 Gy in 3 fractions (one fraction for week). Vaginal ovules containing 5 mg of HA were given for whole duration of vaginal BT and for the two following weeks. Acute and late toxicities were evaluated according to CTCAE vs 4.02. Results According to the revised FIGO 2009 classification, most tumors were in stage IA (30.9%) and in stage IB (57.9%). Thirty-three patients (26.2%) received adjuvant chemotherapy before vaginal BT. Five-year disease-free survival (DFS) and five-year overall survival (OS) were 88% and 93%, respectively. The most common grade 1-2 acute toxicities were vaginal inflammation (18 patients, 14.3%) and dyspareunia (7 patients, 5.5%). Two patients (1.6%) had more than one toxicity. Late toxicity occurred in 20 patients (15.9%). Grade 1-2 late toxicities were fibrosis (14 patients, 11.1%) and telangiectasias (7 patients, 5.5%). Six patients (4.8%) had more than one late toxicity. No grade 3 or higher acute or late toxicities were observed. Conclusions These results appear to suggest that the local therapy with HA is of clinical benefit for intermediate risk endometrial cancer patients who receive adjuvant HDR-vaginal BT after surgery. A randomized trial comparing HA treatment vs. no local treatment in this clinical setting is warranted to further evaluate the efficacy of HA in preventing vaginal BT-related vaginal toxicity.

    We hypothesized that increased baseline BMI and BMI change would negatively impact clinical outcomes with adjuvant breast cancer systemic therapy. Data from chemotherapy trials MA.5 and MA.21; endocrine therapy MA.12, MA.14 and MA.27; and trastuzumab HERA/MA.24 were analyzed. The primary objective was to examine the effect of BMI change on breast cancer-free interval (BCFI) landmarked at 5 years; secondary objectives included BMI changes at 1 and 3 years; BMI changes on disease-specific survival (DSS) and overall survival (OS); and effects of baseline BMI. Stratified analyses included trial therapy and composite trial stratification factors. In pre-/peri-/early post-menopausal chemotherapy trials (N = 2793), baseline BMI did not impact any endpoint and increased BMI from baseline did not significantly affect BCFI (P = 0.85) after 5 years although it was associated with worse BCFI (P = 0.03) and DSS (P = 0.07) after 1 year. BMI increase by 3 and 5 years was associated with better DSS (P = 0.01; 0.01) and OS (P = 0.003; 0.05). In pre-menopausal endocrine therapy trial MA.12 (N = 672), patients with higher baseline BMI had worse BCFI (P = 0.02) after 1 year, worse DSS (P = 0.05; 0.004) after 1 and 5 years and worse OS (P = 0.01) after 5 years. Increased BMI did not impact BCFI (P = 0.90) after 5 years, although it was associated with worse BCFI (P = 0.01) after 1 year. In post-menopausal endocrine therapy trials MA.14 and MA.27 (N = 8236), baseline BMI did not significantly impact outcome for any endpoint. BMI change did not impact BCFI or DSS after 1 or 3 years, although a mean increased BMI of 0.3 was associated with better OS (P = 0.02) after 1 year. With the administration of trastuzumab (N = 1395) baseline BMI and BMI change did not significantly impact outcomes. Higher baseline BMI and BMI increases negatively affected outcomes only in pre-/peri-/early post-menopausal trial patients. Otherwise, BMI

    The discussion on the role of adjuvant chemotherapy for rectal cancer patients treated according to current guidelines is still ongoing. A multicentre, randomized phase III trial, PROCTOR-SCRIPT, was conducted to compare adjuvant chemotherapy with observation for rectal cancer patients treated with preoperative (chemo)radiotherapy and total mesorectal excision (TME). The PROCTOR-SCRIPT trial recruited patients from 52 hospitals. Patients with histologically proven stage II or III rectal adenocarcinoma were randomly assigned (1:1) to observation or adjuvant chemotherapy after preoperative (chemo)radiotherapy and TME. Radiotherapy consisted of 5 × 5 Gy. Chemoradiotherapy consisted of 25 × 1.8-2 Gy combined with 5-FU-based chemotherapy. Adjuvant chemotherapy consisted of 5-FU/LV (PROCTOR) or eight courses capecitabine (SCRIPT). Randomization was based on permuted blocks of six, stratified according to centre, residual tumour, time between last irradiation and surgery, and preoperative treatment. The primary end point was overall survival. Of 470 enrolled patients, 437 were eligible. The trial closed prematurely because of slow patient accrual. Patients were randomly assigned to observation (n = 221) or adjuvant chemotherapy (n = 216). After a median follow-up of 5.0 years, 5-year overall survival was 79.2% in the observation group and 80.4% in the chemotherapy group [hazard ratio (HR) 0.93, 95% confidence interval (CI) 0.62-1.39; P = 0.73]. The HR for disease-free survival was 0.80 (95% CI 0.60-1.07; P = 0.13). Five-year cumulative incidence for locoregional recurrences was 7.8% in both groups. Five-year cumulative incidence for distant recurrences was 38.5% and 34.7%, respectively (P = 0.39). The PROCTOR-SCRIPT trial could not demonstrate a significant benefit of adjuvant chemotherapy with fluoropyrimidine monotherapy after preoperative (chemo)radiotherapy and TME on overall survival, disease-free survival, and recurrence rate. However, this trial did not complete

    Many botanical immunomodulators are used as adjuvants along with cancer chemotherapy. However, information on the impact of concurrent administration of such botanicals on pharmacokinetics of chemotherapy agents is inadequate. This study investigates inhibitory activities of 3 popular botanical adjuvants: ASPARAGUS RACEMOSU: (root aqueous extract; ARE), WITHANIA SOMNIFER: (root aqueous extract; WSE), and TINOSPORA CORDIFOLI: (stem aqueous extract, TCE) on human CYP3A4 isoenzyme, responsible for metabolism of several chemotherapy agents. . Testosterone 6-β hydroxylation was monitored using high-performance liquid chromatography as an indicator of CYP3A4 catalytic activities. Ketoconazole (positive control) and extracts were studied at their in vivo-relevant concentrations. TCE showed mild inhibition while no significant inhibitory activities were observed in WSE and ARE. TCE was further fractionated to obtain polar and nonpolar fractions. The nonpolar fraction showed significant CYP3A4 inhibition with IC50 13.06 ± 1.38 µg/mL. Major constituents of nonpolar fraction were identified using HPLC-DAD-MS profiling as berberine, jatrorrhizine, and palmatine, which showed IC50 values as 6.25 ± 0.30, 15.18 ± 1.59, and 15.53 ± 1.89 µg/mL, respectively. Our findings suggest that constituents of TCE extract especially protoberberine alkaloids have the potential to interact with cancer chemotherapy agents that are metabolized by CYP3A4 in vivo.

    Data quality may impact the outcome of clinical trials; hence, there is a need to implement quality control strategies for the data collected. Traditional approaches to quality control have primarily used source data verification during on-site monitoring visits, but these approaches are hugely expensive as well as ineffective. There is growing interest in central statistical monitoring (CSM) as an effective way to ensure data quality and consistency in multicenter clinical trials. CSM with SMART™ uses advanced statistical tools that help identify centers with atypical data patterns which might be the sign of an underlying quality issue. This approach was used to assess the quality and consistency of the data collected in the Stomach Cancer Adjuvant Multi-institutional Trial Group Trial, involving 1495 patients across 232 centers in Japan. In the Stomach Cancer Adjuvant Multi-institutional Trial Group Trial, very few atypical data patterns were found among the participating centers, and none of these patterns were deemed to be related to a quality issue that could significantly affect the outcome of the trial. CSM can be used to provide a check of the quality of the data from completed multicenter clinical trials before analysis, publication, and submission of the results to regulatory agencies. It can also form the basis of a risk-based monitoring strategy in ongoing multicenter trials. CSM aims at improving data quality in clinical trials while also reducing monitoring costs.

    BACKGROUND: Adjuvant endocrine therapy has significantly improved survival of estrogen receptor α (ER)-positive breast cancer patients, but around 20% relapse within 10 years. High expression of ER-stimulated proteins like progesterone receptor (PR), Bcl-2 and insulin-like growth factor receptor I...... (IGF-IR) is a marker for estrogen-driven cell growth. Therefore, patients with high tumor levels of these proteins may have particularly good prognosis following adjuvant endocrine therapy. PATIENTS AND METHODS: Archival tumor tissue was available from 1323 of 1396 Danish breast cancer patients......, univariate and multivariate analysis revealed HR (95% CI) and p values for disease-free survival (DFS) of 2.00 (1.20-3.22), 0.008 and 1.70 (1.01-2.84), 0.04 and for the overall survival (OS) of 2.33 (1.19-4.57), 0.01 and 1.90 (0.97-3.79), 0.06, respectively.

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

    BACKGROUND: The Danish Breast Cancer Cooperative Group (DBCG) 77B trial examined the relative efficacy of levamisole, single-agent oral cyclophosphamide, and the classic combination of cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) against no adjuvant systemic therapy in high-risk breast...... cancer patients. The authors report the results from that trial after a potential follow-up of 25 years. METHODS: Between 1977 and 1983, 1146 premenopausal patients who had tumors >5 cm or positive axillary lymph nodes were assigned randomly to 1 of 4 options: no systemic therapy, levamisole 5 mg weekly...... for 48 weeks (the levamisole arm), oral cyclophosphamide 130 mg/m(2) on Days 1 through 14 every 4 weeks for 12 cycles (the C arm), or oral cyclophosphamide 80 mg/m(2) on Days 1 through 14 plus methotrexate 30 mg/m(2) and fluorouracil 500 mg/m(2) intravenously on Days 1 and 8 every 4 weeks for 12 cycles...

    DFS: low [81.7%] versus high [70.4%]; P=0.016 and in patients without adjuvant chemotherapy (3-year DFS: low [91.7%] versus high [22.3%]; P<0.001, but not in patients receiving adjuvant chemotherapy (P=0.552. DFS stratified by PTK7 expression was compared in treatment cohorts: In patients with low LN PTK7 expression, neither chemotherapy cohort showed significantly better survival than the no-chemotherapy cohort. In patients with high LN PTK7 expression, those receiving chemotherapy, including substances other than anthracyclines, but not those receiving only anthracycline-based chemotherapy, showed significantly better DFS than those receiving no chemotherapy (P=0.001. Our results support earlier findings that PTK7 may be a prognostic and predictive marker associated with resistance to anthracycline-based chemotherapy. Further investigations are needed to validate these findings in breast cancer.Keywords: breast cancer, PTK7, protein tyrosine kinase 7, chemoresistance, prognostic factors, predictive factors

    Pretreatment lymphocyte count (LC) has been associated with prognosis and chemotherapy response in several cancers. The predictive value of LC for stage II colorectal cancer (CRC) and for high-risk patients treated with adjuvant chemotherapy (AC) has not been determined. A retrospective review of prospectively collected data from 1332 consecutive stage II CRC patients who underwent curative tumor resection was conducted. A pretreatment LC value risk, 459 (62.2%) of whom received AC. Patients with low LCs had significantly worse 5-year OS (74.6% vs. 90.2%, p risk patients with low LCs had the poorest DFS (p value or combined with high-risk status were both independent prognostic factors(p risk, AC-treated patients with high LCs had significantly longer DFS than untreated patients (HR, 0.594; 95% CI, 0.364-0.970; p = 0.035). There was no difference or trend for DFS or OS in patients with low LCs, regardless of the use of AC (DFS, p = 0.692; OS, p = 0.522). Low LC was also independently associated with poorer DFS in high-risk, AC-treated patients (HR, 1.885; 95% CI, 1.112-3.196; p = 0.019). Pretreatment LC is an independent prognostic factor for survival in stage II CRC. Furthermore, pretreatment LC reliably predicts chemotherapeutic efficacy in high-risk patients with stage II CRC.

    Implications of adjuvant radiotherapy (intraoperative and postoperative) for pancreatic carcinoma were investigated. In the examination of autopsy, it was confirmed that local recurrence was controlled by irradiation, but frequency of local recurrence and liver metastasis was high, and the prognosis was poor. Local recurrence rate was 13.3% in 15 cases which had intraoperative irradiation of 30 Gy and 40% in 10 cases of irradiation under 30 Gy. After 1994, postoperative irradiation for whole liver was added to local intraoperative irradiation, and good results were obtained (10 of 19 cases are alive). Liver metastasis rate was 21.1% in whole liver irradiation group, and about 50% in other groups. Recently, local intraoperative irradiation of 30 Gy with whole liver irradiation of 22 Gy was adopted as standard adjuvant radiotherapy and better results were obtained. But it is too early to conclude their effects. (K.H.)

    Lung carcinoma remains an enormous clinical challenge for all health care personnel involved in the care of these patients. Those patients with unresected primary lung carcinoma are ultimately referred for radiation therapy in order to control local regional disease. It is important to recognize the great gains in longevity have not materialized with the addition of adjuvant therapy. However, a very real benefit in the quality of life for most patients with carcinoma of the lung can be achieved with the judicious and thoughtful application of sophisticated radiation therapy, for a small but significant portion of the population, a cure will result from this treatment. This chapter reviews the role of radiation therapy as an adjuvant to definitive surgical treatment

    Full Text Available Neoadjuvant chemotherapy (NAC is widely used in locally advanced breast cancer (BC treatment. The role of postmastectomy radiotherapy (PMRT after NAC is strongly debated. The aim of our analysis was to identify major prognostic factors in a single-center series, with emphasis on PMRT. From 1997 to 2011, 170 patients were treated with NAC and mastectomy at our center; 98 cases (57.6% underwent PMRT and 72 cases (42.4% did not receive radiation. At a median follow-up period of 7.7 years (range 2–16 for the whole cohort, median time to locoregional recurrence (LRR was 3.3 years (range 0.7–12.4. The 5-year and 10-year actuarial LRR rate were 14.5% and 15.9%, respectively. At the multivariate analysis the factors that significantly correlated with survival outcome were ≥4 positive nodes (HR 5.0, 1.51–16.52; P=0.035, extracapsular extension (HR 2.18, 1.37–3.46; P=0.009, and estrogen receptor positive disease (HR 0.57, 0.36–0.90; P=0.003. Concerning LRR according to use of radiation, PMRT reduced LRR for patient with clinical T3 staged disease (P=0.015. Our experience confirmed the impact of pathological nodal involvement on survival outcome. PMRT was found to improve local control in patients presenting with clinical T3 tumors, regardless of the response to chemotherapy.

    The aim of this study was to report the clinical outcome and toxicity of radiochemotherapy in locally advanced gastric cancer (LAGC) patients treated according to the Intergroup 116 trial protocol in our institution. We retrospectively reviewed 105 patients with LAGC treated with radical surgery and adjuvant radiochemotherapy. We analyzed overall survival (OS), disease-free survival (DFS), locoregional failure-free survival (LFS), prognostic factors and toxicity. The mean follow-up was 96.48 months. The majority of tumors were T3-T4 (75%) and 86.6% had nodal metastases. The OS, DFS and LFS rates to 3 years were 53.48%, 52.75% and 81.65%, respectively and to 5 years 40%, 46.73% and 76.77% respectively. The univariate analysis showed that N stage < N2, TN stage < IIIA, R0 resection and N-ratio < 3 were statistically significant prognostic factors for OS and DFS, T stage < T4 for OS and N-ratio < 3 for LFS. The group with D2 lymphadenectomy had worse LFS than the D1 group (65.2% vs 88.1%, respectively, p = 0.039) probably due to a significant difference in the proportion node positive patients in the D2 group (94% vs. 78%; p = 0.027). In the multivariate analysis, only R0 resection was statistically significant factor for improved OS (p = 0.018). Acute grade III-IV gastrointestinal and hematologic toxicity rates were 8.5% and 15.2%, respectively and 89.5% completed treatment as planned. Our results are consistent with those of the Intergroup-0116 trial for LAGC in terms of survival. This regimen is well tolerated and with acceptable toxicity. An R0 resection was an independent prognostic factor for improved OS. (orig.)

    The National Institute for Health and Clinical Excellence (NICE) recommended the Oncotype DX ® Breast Recurrence Score ® (RS) assay as an option for informing adjuvant chemotherapy decisions in node-negative, oestrogen receptor (ER)+, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer assessed to be at intermediate risk of recurrence based on clinicopathological factors. We evaluated the impact of RS testing on adjuvant chemotherapy decision-making in routine clinical practice in a UK Cancer Network. RS testing was performed in 201 females with newly diagnosed, ER+, HER2-negative, invasive breast cancer who underwent breast surgery with curative intent, were calculated to have a >3% overall survival benefit at 10 years from adjuvant chemotherapy based on PREDICT, and were considered for adjuvant chemotherapy. The impact of RS testing on adjuvant treatment decisions/associated cost was assessed. In all patients, the multi-disciplinary team recommended chemotherapy but the RS result allowed 127/201 patients (63.2%) to avoid unnecessary adjuvant chemotherapy. Amongst ER+, HER2-negative, node-negative patients (eligible for Oncotype DX testing in UK guidelines), 60.3% were spared chemotherapy. In node-positive patients, the assay reduced the use of chemotherapy by 69.2%. The use of RS testing to guide treatment in these 201 patients was associated with significant cost saving (when considering the cost of RS testing for all patients plus chemotherapy and its associated cost for 74 patients). Incorporating RS testing into routine clinical practice for selected node-negative and node-positive breast cancer patients significantly reduces the use of chemotherapy (p < 0.001) with its associated morbidity and costs.

    This paper presents long-term results from a randomized trial of pre- or postoperative megavoltage radiation therapy versus surgery alone in pre- and postmenopausal women with operable breast cancer. Treatment outcome after relapse among patients who developed loco-regional recurrences was also analyzed. A total of 960 patients were included in the trial. The mean follow-up was 16 years (range: 13-19 years). The radiation therapy was individually planned. It included the chest wall (and the breast in the preoperative cases) and the regional lymph nodes. The tumor dose was 45 Gy/5 weeks. No adjuvant systemic therapy was used. The results showed a significant benefit with radiation therapy in terms of recurrence-free survival during the entire follow-up period. There was also an overall survival difference-corresponding to a 16% reduction of deaths-in favor of the irradiated patients which, however, was not statistically significant (p = 0.09). Among those 169 patients who developed locoregional recurrences long-term control was only achieved in about one-third of the cases. This figure was similar among those who had received adjuvant radiation therapy (34%) compared to those initially treated with surgery alone (32%). This implied that the overall proportion of patients who eventually developed uncontrolled local disease was significantly higher among those initially allocated to surgery alone (16%) compared to those allocated to pre- or postoperative radiation therapy (6%, p < 0.01). These results suggest that local undertreatment may be deleterious in subgroups of patients.

    Purpose: To develop multi-institutional consensus clinical target volumes (CTVs) and organs at risk (OARs) for male and female bladder cancer patients undergoing adjuvant radiation therapy (RT) in clinical trials. Methods and Materials: We convened a multidisciplinary group of bladder cancer specialists from 15 centers and 5 countries. Six radiation oncologists and 7 urologists participated in the development of the initial contours. The group proposed initial language for the CTVs and OARs, and each radiation oncologist contoured them on computed tomography scans of a male and female cystectomy patient with input from ≥1 urologist. On the basis of the initial contouring, the group updated its CTV and OAR descriptions. The cystectomy bed, the area of greatest controversy, was contoured by another 6 radiation oncologists, and the cystectomy bed contouring language was again updated. To determine whether the revised language produced consistent contours, CTVs and OARs were redrawn by 6 additional radiation oncologists. We evaluated their contours for level of agreement using the Landis-Koch interpretation of the κ statistic. Results: The group proposed that patients at elevated risk for local-regional failure with negative margins should be treated to the pelvic nodes alone (internal/external iliac, distal common iliac, obturator, and presacral), whereas patients with positive margins should be treated to the pelvic nodes and cystectomy bed. Proposed OARs included the rectum, bowel space, bone marrow, and urinary diversion. Consensus language describing the CTVs and OARs was developed and externally validated. The revised instructions were found to produce consistent contours. Conclusions: Consensus descriptions of CTVs and OARs were successfully developed and can be used in clinical trials of adjuvant radiation therapy for bladder cancer.

    The impact of in vitro chemosensitivity test-guided platinum-based adjuvant chemotherapy on the surgical outcomes of patients undergoing complete resection for locally advanced non-small cell lung cancer (NSCLC) has yet to be elucidated. In the present study, the utility of adjuvant chemotherapy based on the collagen gel droplet embedded culture drug sensitivity test (CD-DST) in patients with p (pathology)-stage IIIA NSCLC was retrospectively analyzed. A series of 39 patients that had received platinum-based adjuvant chemotherapy following complete resection between 2007 and 2012 were enrolled. Their surgical specimens were subjected to the CD-DST. The patients were subsequently classified into two groups on the basis of in vitro anti-cancer drug sensitivity data obtained using the CD-DST: The sensitive group (25 patients) were treated with regimens including one or two of the anti-cancer drug(s) that were indicated to be effective by the CD-DST, whereas the non-sensitive group (14 patients) were treated with chemotherapy regimens that did not include any CD-DST-selected anti-cancer drugs. There were no significant differences in the background characteristics of the two groups [including in respect of the pathological TN (tumor-lymph node) stage, tumor histology, epidermal growth factor receptor mutation status, the frequency of each chemotherapy regimen, and the number of administered cycles]. The 5-year disease-free survival (DFS) rate of the sensitive group was 32.3%, whereas that of the non-sensitive group was 14.3% (P=0.037). In contrast, no difference in overall survival (OS) was observed (P=0.76). Multivariate analysis revealed that adjuvant chemotherapy based on the CD-DST had a significant favorable effect on the DFS (P=0.01). Therefore, the present study has demonstrated that CD-DST data obtained from surgical specimens aid the selection of effective platinum-based adjuvant chemotherapy regimens for patients undergoing complete resection for p-stage IIIA

    The AZURE trial is an ongoing phase III, academic, multi-centre, randomised trial designed to evaluate the role of zoledronic acid (ZOL) in the adjuvant therapy of women with stage II/III breast cancer. Here, we report the safety and tolerability profile of ZOL in this setting. Eligible patients received (neo)adjuvant chemotherapy and/or endocrine therapy and were randomised to receive neither additional treatment nor intravenous ZOL 4 mg. ZOL was administered after each chemotherapy cycle to exploit potential sequence-dependent synergy. ZOL was continued for 60 months post-randomisation (six doses in the first 6 months, eight doses in the following 24 months and five doses in the final 30 months). Serious (SAE) and non-serious adverse event (AE) data generated during the first 36 months on study were analysed for the safety population. 3,360 patients were recruited to the AZURE trial. The safety population comprised 3,340 patients (ZOL 1,665; control 1,675). The addition of ZOL to standard treatment did not significantly impact on chemotherapy delivery. SAE were similar in both treatment arms. No significant safety differences were seen apart from the occurrence of osteonecrosis of the jaw (ONJ) in the ZOL group (11 confirmed cases; 0.7%; 95% confidence interval 0.3-1.1%). ZOL in the adjuvant setting is well tolerated, and can be safely administered in addition to adjuvant therapy including chemotherapy. The adverse events were consistent with the known safety profile of ZOL, with a low incidence of ONJ.

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

    In oncology, hypnosis has been used for pain relief in metastatic patients but rarely for induction of anesthesia. Between January 2010 and October 2015, 300 patients from our Breast Clinic (Cliniques universitaires Saint-Luc, Université catholique de Louvain) were included in an observational, non-randomized study approved by our local ethics committee (ClinicalTrials.gov - NCT03003611). The hypothesis of our study was that hypnosis intervention could decrease side effects of breast surgery. 150 consecutive patients underwent breast surgery while on general anesthesia (group I), and 150 consecutive patients underwent the same surgical procedures while on hypnosis sedation (group II). After surgery, in each group, 32 patients received chemotherapy, radiotherapy was administered to 123 patients, and 115 patients received endocrine therapy. Duration of hospitalization was statistically significantly reduced in group II versus group I: 3 versus 4.1 days (p = 0.0000057) for all surgical procedures. The number of post-mastectomy lymph punctures was reduced in group II (1-3, median value n = 1.5) versus group I (2-5, median value n = 3.1) (p = 0.01), as was the quantity of lymph removed (103 ml versus 462.7 ml) (p = 0.0297) in the group of mastectomies. Anxiety scale was also statistically reduced in the postoperative period among the group of patients undergoing surgery while on hypnosis sedation (p = 0.0000000000000002). The incidence of asthenia during chemotherapy was statistically decreased (p = 0.01) in group II. In this group, there was a statistically non-significant trend towards a decrease in the incidence of nausea/vomiting (p = 0.1), and the frequency of radiodermitis (p = 0.002) and post-radiotherapy asthenia (p = 0.000000881) was also reduced. Finally, the incidence of hot flashes (p = 0.0000000000021), joint and muscle pain (p = 0.0000000000021) and asthenia while on endocrine therapy (p = 0.000000022) were statistically

    Full Text Available BACKGROUND: Adjuvant trastuzumab therapy has yielded conflicting results for overall survival, concerns about central nervous system (CNS metastasis, and questions about optimal schedule. Therefore, we carried out a meta-analysis to assess the benefits of concurrent or sequential trastuzumab with adjuvant chemotherapy for early breast cancer patients with HER2-positive tumors. METHODS: Computerized and manual searches were performed to identify randomized clinical trials comparing adjuvant chemotherapy with or without trastuzumab in HER2-positive early breast cancer patients. Odds ratios were used to estimate the association between the addition of trastuzumab to adjuvant chemotherapy and various survival outcomes. The fixed-effects or random-effects model was used to combine data. FINDINGS: With six eligible studies identified, this analysis demonstrated that patients with HER2-positive breast cancer derived benefit in disease-free survival, overall survival, locoregional recurrence and distant recurrence (all P<0.001 from the addition of trastuzumab to adjuvant chemotherapy, whereas trastuzumab did worse in CNS recurrence as compared to the control group (P = 0.018. Furthermore, concomitant use of trastuzumab significantly lowered the hazard of death (P<0.001 but bore a higher incidence of CNS recurrence (P = 0.010, while statistical significance failed to be discerned for either overall survival (P = 0.069 or CNS metastasis (P = 0.374 between the sequential and observation arms. CONCLUSION: This analysis verifies the efficacy of trastuzumab in the adjuvant setting. Additionally, our findings indirectly corroborate the superiority of concurrent trastuzumab to sequential use and also illuminate that prolonged survival is the possible reason for the higher incidence of CNS with trastuzumab versus observation.

    Dignity therapy is a psychosocial intervention that has been used primarily at the end of life to improve quality of life and other patient outcomes, but many individuals are unable to complete it due to health decline and death. The purpose of this study was to identify what individuals with advanced pancreatic or lung cancer with limited life expectancy, undergoing active cancer treatment describe during the dignity therapy intervention as important to them when not immediately facing end of life. Twenty patients undergoing chemotherapy for advanced cancer participated in a dignity therapy intervention study. Initial interviews were analyzed using descriptive content analysis. Family provided the overall context and background for emerging themes of defining events, accomplishments, and God's plan, which led to lessons learned, and resulted in messages of hope. Interviews were often autobiographical in nature and contained much reminiscence, consistent with dignity therapy's intent. Few parti
