Background: Although the benefit of supportive care in the postcancer period is now well demonstrated, its implementation in the patient journey remains challenging. This article describes the development, since 2015 and in routine care, of supportive postcancer care comprising a multidisciplinary rehabilitation programme (MRP) based on exercise for patients with early breast cancer., Methods: As part of quality control, we reviewed all patient files since the programme was implemented. Patient data regarding the type of cancer, clinical and pathological factors, and treatment were recorded in a computerised database., Results: From April 2015 to January 2024, 655 patients participated in the MRP. The programme lasts for 14 weeks, totalling 126 hours of face-to-face programme, with a maximum of 8 patients per group, in 5 different centres. A multidisciplinary professional team provide supportive care. The MRP is mainly based on supervised physical exercise and patients also participate in social, psychological, dietary support and educational sessions. Supervised physical exercise includes cardiorespiratory endurance work through specific sessions on ergometers or outdoor walking and adapted physical activity sessions to improve muscular capacities (endurance, strength and flexibility)., Conclusion: We describe here the practical implementation of a routine multidisciplinary supportive care programme, based mainly on physical activity, for post-treatment breast cancer patients. We report almost 9 years of experience with the programme. We show that offering this programme in the postcancer setting and in clinical routine practice is feasible and can be maintained in the long term., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Context and Aims: Eribulin is used in taxane and anthracycline refractory HER2-negative metastatic breast cancers (MBC). Patients treated in pivotal clinical trials achieved low survival rates, therefore, the identification of prognostic criteria for long progression-free survival (PFS) is still an unmet medical need. In this study, we sought to determine potential prognostic criteria for long-term eribulin response in HER2-negative MBC., Methods: Our retrospective cohort includes female patients with HER2-negative MBC treated with eribulin in Franche-Comté, France. We defined a long-term response as at least 6 months of eribulin treatment. The primary endpoint was the analysis of criteria that differ according to the progression-free survival. Secondary outcomes concerned overall survival and response rate., Results: From January 2011 to April 2020, 431 patients treated with eribulin were screened. Of them, 374 patients were included. Median PFS was 3.2 months (2.8-3.7). Eighty-eight patients (23.5%) had a long-term response to eribulin. Four discriminant criteria allowed to separate PFS in 2 arms (PFS < 3 months or > 6 months) with a 78% positive predictive value: histological grade, absence of meningeal metastasis, response to prior chemotherapy, and OMS status. We have developed a nomogram combining these 4 criteria. Median overall survival was 8.5 months (7.0-9.5)., Conclusion: Eribulin response in MBC can be driven by clinical and biological factors. Application of our nomogram could assist in the prescription of eribulin., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Background: Up to 70% of breast cancer patients report symptoms of insomnia during and after treatment. Despite the ubiquity of insomnia symptoms, they are under-screened, under-diagnosed and poorly managed in breast cancer patients. Sleep medications treat symptoms but are ineffective to cure insomnia. Other approaches such as cognitive behavioral therapy for insomnia, relaxation through yoga and mindfulness are often not available for patients and are complex to implement. An aerobic exercise program could be a promising treatment and a feasible option for insomnia management in breast cancer patients, but few studies have investigated the effects of such a program on insomnia., Methods: This multicenter, randomized clinical trial evaluate the effectiveness of a moderate to high intensity physical activity program (45 min, 3 times per week), lasting 12 weeks, in minimizing insomnia, sleep disturbances, anxiety/depression, fatigue, and pain, and in enhancing cardiorespiratory fitness. Patients with breast cancer be recruited from six hospitals in France and randomly allocated to either the "training" or the "control" group. Baseline assessments include questionnaires [Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index questionnaire (PSQI), Hospital Anxiety Depression Scale (HADS), Epworth Sleepiness Scale (ESS)], home polysomnography (PSG), and 7-day actigraphy coupled with completion of a sleep diary. Assessments are repeated at the end of training program and at six-month follow-up., Discussion: This clinical trial will provide additional evidence regarding the effectiveness of physical exercise in minimizing insomnia during and after chemotherapy. If shown to be effective, exercise intervention programs will be welcome addition to the standard program of care offered to patients with breast cancer receiving chemotherapy., Trial Registration: National Clinical Trials Number (NCT04867096)., (© 2023.

Background: Trastuzumab is used, alone or in conjunction with standard chemotherapy, to treat HER2-positive breast cancer (BC). Although it improves cancer outcomes, trastuzumab. can lead to cardiotoxicity. Physical exercise is a safe and effective supportive therapy in the management of side effects, but the cardioprotective effects of exercise are still unclear., Objectives: The primary aim of this study was to test whether trastuzumab-induced cardiotoxicity [left ventricular ejection fraction (LVEF) under 50%, or an absolute drop in LVEF of 10%] was reduced after a supervised exercise program of 3 months in patients with HER2-positive breast cancer. Secondary endpoints were to evaluate (i) cardiotoxicity rates using other criteria, (ii) cardiac parameters, (iii) cardiorespiratory fitness and (iv) whether a change in LVEF influences the cardiorespiratory fitness., Methods: 89 women were randomized to receive adjuvant trastuzumab in combination with a training program (training group: TG; n = 46) or trastuzumab alone (control group: CG; n = 43). The primary and secondary endpoints were evaluated at the end of the supervised exercise program of 3 months (T3)., Results: After exercise program, 90.5 % of TG patients and 81.8% of CG patients did not exhibit cardiotoxicity. Furthermore, whatever the used criterion, percentage of patients without cardiotoxicity were greater in TG (97.6 and 100% respectively) than in CG (90.9 and 93.9% respectively). LVEF and GLS values remained stable in both groups without any difference between the groups. In contrast, at T3, peak VO 2 (+2.6 mL.min -1 .kg -1 ; 95%CI, 1.8 to 3.4) and maximal power (+21.3 W; 95%CI, 17.3 to 25.3) increased significantly in TG, whereas they were unchanged in CG (peak VO 2 : +0.2 mL.min -1 .kg -1 ; 95%CI, -0.5 to 0.9 and maximal power: +0.7 W, 95%CI, -3.6 to 5.1) compared to values measured at T0. No correlation between LVEF changes and peak VO 2 or maximal power was observed., Conclusion: A 12-week supervised exercise regimen was safe and improved the cardiopulmonary fitness in particular peak VO 2 , in HER2-positive BC patients treated with adjuvant trastuzumab therapy. The study is under powered to come to any conclusion regarding the effect on cardiotoxicity., Clinical Trial Registration: www.ClinicalTrials.gov, identifier: NCT02433067., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Jacquinot, Meneveau, Falcoz, Bouhaddi, Roux, Degano, Chatot, Curtit, Mansi, Paillard, Bazan, Chaigneau, Dobi, Meynard, Vernerey, Pivot and Mougin.)

Breast cancers expressing high levels of Ki67 are associated with poor outcomes. Oncotype DX test was designed for ER+/HER2- early-stage breast cancers to help adjuvant chemotherapy decision by providing a Recurrent Score (RS). RS measures the expression of 21 specific genes from tumor tissue, including Ki67. The primary aim of this study was to assess the agreement between Ki67 RNA obtained with Oncotype DX RS and Ki67 IHC . Other objectives were to analyze the association between the event free survival (EFS) and the expression level of Ki67 RNA ; and association between RS and Ki67 RNA . Herein, we report a low agreement of 0.288 by Pearson correlation coefficient test between Ki67 IHC and Ki67 RNA in a cohort of 98 patients with early ER+/HER2- breast cancers. Moreover, Ki67 RNA high tumors were significantly associated with the occurrence of events (p = 0.03). On the other hand, we did not find any association between Ki67 IHC and EFS (p = 0.26). We observed a low agreement between expression level of Ki67 RNA and Ki67 protein labelling by IHC. Unlike Ki67 IHC and independently of the RS, Ki67 RNA could have a prognostic value. It would be interesting to better assess the prognosis and predictive value of Ki67 RNA measured by qRT-PCR. The Ki67 RNA in medical routine could be a good support in countries where Oncotype DX is not accessible., (© 2022. The Author(s).)

Aim: Raltitrexed (RTX) is a thymidylate synthase inhibitor with large pharmacokinetics (PK) variability that can be administered in case of 5-fluorouracil (5FU) intolerance or dihydropyrimidine dehydrogenase deficiency. While it is a more potent thymidylate synthase inhibitor than 5FU, RTX failed to replace this drug for colorectal cancer patients, mainly due to its toxicity at the recommended dose of 3 mg/m 2 every 3 weeks. However, every 2 weeks administration at 2 mg/m 2 demonstrated a favourable toxicity profile., Method: We performed a randomized crossover comparative population PK study between every 2 weeks TOMOX (RTX 2 mg/m 2 ) and every 3 weeks TOMOX (RTX 3 mg/m 2 )., Results: A three-compartment model and a proportional error model best describe the data. Creatinine clearance and sex, but not body surface area (BSA), were covariates of RTX clearance leading to decrease of its interindividual variability of 28%. Weight and body surface area were covariates of central and peripheral volumes of distribution, respectively, leading to decreases of interindividual variability of 34.6% and 100%, respectively. In contrast to the dose, AUC was a good predictor of liver toxicity (P = 0.006, OR = 3.91, 95%CI = [1.48-10.34]). Using covariates to compute individual clearance and a threshold AUC (1.639, determined in this study), a covariates-based dose was calculated, leading to less variability in AUC than observed with the actual BSA-based or fixed doses., Conclusion: These results advocate for the use of creatinine clearance and sex to determine the RTX dose instead of BSA., (© 2020 The British Pharmacological Society.)

Background: Infusion of high-dose intravenous methotrexate (MTX) has been demonstrating to penetrate the blood-brain barrier. The aim of this present study was to assess the efficacy and safety of high dose MTX in patients with central nervous system (CNS) metastases of breast cancer., Methods: Twenty-two patients with CNS metastases treated by MTX (3 g/m2) between April 2004 and October 2009 were enrolled. Clinical response rate, time to progression (TTP), overall survival (OS), and safety were assessed., Results: In terms of brain metastases, 2 patients (9%) achieved a partial response, 10 patients (45%) had disease stabilization, and 10 patients (45%) had disease progression. In others metastatic sites, 7 patients (39%) achieved a disease stabilization, and 11 patients (61%) had disease progression. TTP and OS were 2.1 (95%CI 1.4-2.9) and 6.3 (95%CI 1.8-10) months, respectively., Conclusion: High-dose MTX demonstrated a moderate activity at 3 g/m 2 . Nonetheless, the favorable toxicity profile should suggest the possibility to increase the dosage and further study are planned.

Background: Sunitinib is a tyrosine kinase inhibitor approved in the first-line metastatic renal cell carcinoma (MRCC) setting at the dose of 50 mg daily for 4 weeks followed by a pause of 2 weeks. Due to toxicity, this standard schedule (50 mg daily 4/2) can induce up to 50% of sunitinib dose modification (reduction and/or interruption). The current recommendation in such case is to reduce the dose to 37.5 mg per day (standard schedule 4/2). Recent data highlight an alternative schedule: 2 weeks of treatment followed by 1 week of pause (experimental schedule 2/1). The SURF trial is set up to evaluate prospectively experimental schedule 2/1 when toxicity occurs. This article displays the key elements of the study protocol., Methods/design: SURF [NCT02689167] is a prospective, randomized, open-label phase IIb study. Patients are included at sunitinib initiation while receiving standard schedule 4/2 (50 mg daily) according to the marketing authorization indication. When a dose adjustment of sunitinib is required, patients are randomized between standard schedule 4/2 (37.5 mg daily) and experimental schedule 2/1 (50 mg daily). Key eligibility criteria are the following: patients with locally advanced inoperable or MRCC who are starting first-line treatment with sunitinib, with histologically or cytologically confirmed renal cancer clear cell variant or with a clear cell component, and with Karnofsky performance status ≥70%. The primary objective is to assess the median duration of sunitinib treatment (DOT) in each group. The key secondary objectives are progression-free survival, overall survival, time to randomization, objective response rate, safety, sunitinib dose intensity, health-related quality of life, and the description of main drivers triggering randomization. We hypothesized that experimental schedule 2/1 would result in an improvement in median DOT from 6 to 8.5 months. It was estimated that 112 patients would be needed in each arm during 24 months. In order to take into account the possibility of treatment discontinuation before randomization, 248 patients are necessary., Discussion: The SURF trial is asking a pragmatic question adapted to the current practice on what is the best way to adapt sunitinib when treatment-related adverse events occur. The results of the SURF trial will bring high-value data to support the use of an alternative schedule in sunitinib treatment., Trial Registration: ClinicalTrials.gov, NCT02689167 .

Background: Enterocolitis is a rare, but serious gastrointestinal complication associated with docetaxel-based chemotherapy in patients with cancer. The incidence, clinical presentation and outcome of enterocolitis in patients with cancer treated with docetaxel-based chemotherapy was assessed in this study Patients and Methods: All patients treated with docetaxel for cancer between January 2010 and December 2014 at the University Hospital of Besançon were identified and their medical records reviewed., Results: During this period, 1,227 patients received docetaxel chemotherapy and gastrointestinal events occurred in 381 (31.1%) patients. In multivariate analysis, a higher risk of gastrointestinal events was associated with a higher dose of docetaxel (≥75 mg/m 2 ) (odds ratio(OR)=46.2; 95% confidence interval(CI)=5.4-397.0, p=0.0005) and the first cycle of docetaxel (OR=4.2; 95% CI=1.8-10.1, p=0.001). Among the 381 patients with gastrointestinal events, grade 3/4 neutropenia, diarrhea, febrile neutropenia, mucositis, nausea/vomiting, and rectal bleeding were diagnosed in 65 (17.1%), 51 (13.4%), 37 (9.7%); 12 (3.1%), seven (1.8%) and three (0.8%) patients, respectively; 54 patients (14.2%) were hospitalized. Computed tomographic scan was performed for 39 patients (10.2%). Twenty-seven patients presented radiological signs of enterocolitis. Three deaths (0.8%) related to enterocolitis were recorded. Docetaxel was resumed in 261 patients (68.5%) and the dose was reduced in 89 patients (23.4%). Docetaxel was discontinued in 120 patients (31.5%)., Conclusion: Gastrointestinal events in patients treated with docetaxel may be a potential sign of fatal enterocolitis and require particular attention. Dose reduction at the first cycle may reduce the risk of such events., (Copyright© 2018, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

Raltitrexed is a thymidylate synthase inhibitor that can be administered safely to patients with cardiovascular disease or dihydropyrimidine dehydrogenase deficiency, as opposed to 5FU. The recommended dose of 3mg/m 2 every 3 weeks often leads to toxicity. Interestingly, the 2mg/m 2 every 2 weeks dose appears to be less toxic. A pharmacokinetic trial was then performed by our team to investigate such phenomenon. However, there are currently, two main methods for RTX measurement described in the literature: a radioimmunoassay (RIA) and chromatographic-based methods with either UV or mass spectrometry detections. The RIA methods: display a low limit of quantification (below 1μg/L), but also a low extent of linearity for the calibration curve. The chromatographic-based methods: include high level of calibrators, but have poor sensitivity (>2μg/mL). If a high sensitivity is essential to satisfactorily describe the elimination of RTX, high concentrations in the calibration curve are also needed to avoid bias linked to the dilutions of the samples. A new LC-MS/MS method was then developed that allows to simultaneously measure very low (0.1μg/L) and very high (3000μg/L) concentrations in the same run. Moreover, the extraction steps are very simple and fast with mainly a precipitation and a filtration steps. This method was validated following the EMA recommendations. In view of the extent of the calibration curve, the carry-over effect was more deeply investigated. With this method, it was possible to measure RTX in samples taken 3 weeks after the administration. Taken together, this method allows to simply and quickly measure RTX in plasma of patients., (Copyright © 2017 Elsevier B.V. All rights reserved.)

Introduction: No guideline for time-to-event endpoints (TTEE) definitions in lung cancer trials exists. Areas covered: The aim of the study was to evaluate the reporting of TTEE in operable non-small-cell lung cancer randomized clinical trials. Expert commentary: Sixty-two TTEE were recorded. In the Methods section, using four key points to define TTEE we observed that the 'starting point', 'events', 'information on censoring', 'assessment of events' were clearly defined for 43 (69.4%), 34 (54.8%), 6 (9.7%), 33 (53.2%) endpoints respectively. In the results section, using five key points, we observed that the 'Kaplan-Meier estimation', 'estimation of effect size', 'precision (confidence interval)', 'number of events', 'number of patients at risk', 'multivariate analysis' were clearly identified for 46 (74.2%), 31 (50%), 30 (48.4%), 37 (59.7%), 28 (45.2%), and 17 (27.4%) endpoints, respectively. A majority of articles failed to provide a complete reporting of TTEE. Guidelines for TTEE is warranted.

Introduction: Pain management is a major public health problem, especially in oncology. In order to assess professional practice, the IRFC-FC conducted a survey amongst patients with metastatic osteophilic solid tumor in Franche-Comté. The aims were to assess the pain prevalence, and its characteristics, its management and its impact on patients' quality of life in patients in pain., Methods: An observational, prospective and multicenter survey was conducted using a self-report questionnaire. Patients with metastatic breast or prostate cancer managed in 5 day-hospitals of the IRFC-FC over a period of three months were included., Results: Two hundred thirty-three questionnaires were analyzed. Pain prevalence rate was 48.5%. Three quarters of patients in pain had chronic background pain, moderate to severe, with or without breakthrough pain. Considering their pain intensity and their analgesic therapy, 42.0% of patients seem to have an inadequate treatment. Eighty-five percent of treated patients reported to be compliant and felt that their pain was well managed despite a strong impact on their quality of life., Conclusion: The setting of a specific clinical pathway is essential to secure the standardized, optimal and efficient management of patients in pain. The assessment of patient satisfaction and quality of life must be integrated in clinical practice to identify patients in pain for which the treatment is inappropriate., (Copyright © 2016 Société Française du Cancer.

Eribulin gained its approval in March 2011 for the treatment of patients with locally advanced or metastatic breast cancer (MBC) whose disease has progressed despite anthracycline and taxane-containing regimens. This study retrospectively assessed the efficacy, safety and cost of this treatment for all patients with MBC treated by eribulin in Franche-Comté. Ninety-four patients received eribulin between July 2006 and October 2013. The median age was 62 years (35-83). Median overall survival was 10.3 months [95% CI: 7.6 to 17.9]. Median progression-free-survival was 3.8 months [95% CI: 2.9 to 5.0]. Clinical benefit was obtained in 55% evaluable patients [95% CI: 43.1 to 66.9] by RECIST criteria. Most common grade 3-4 adverse events (AEs) were neutropenia (38%), asthenia (10%) and peripheral neuropathy (7%). Median cost of the treatment was 9767 € per patient (6344-17,517). This analysis found similar results to the EMBRACE study despite less selected population. A medico-economic evaluation cost-utility type would assess the effectiveness of this strategy compared to standard treatments., (Copyright © 2015 Société Française du Cancer.

Cisplatin/gemcitabine association has been a standard of care for first-line regimen in advanced biliary tract cancer nevertheless oxaliplatin/gemcitabine regimen is frequently preferred. Because comparative effectiveness in clinical outcomes of cisplatin- versus oxaliplatin-containing chemotherapy is not available, a systematic review of studies assessing cisplatin/gemcitabine or oxaliplatin/gemcitabine chemotherapies in advanced biliary tract cancer was performed. Published studies evaluating cisplatin/gemcitabine or oxaliplatin/gemcitabine in advanced biliary tract cancer were included. Each study was weighted according to the number of patients included. The primary objective was to assess weighted median of medians overall survival (mOS) reported for both regimens. Secondary goals were to assess weighted median of medians progression-free survival (mPFS) and toxic effects were pooled and compared within each arm. Thirty-three studies involving 1470 patients were analyzed. In total, 771 and 699 patients were treated by cisplatin/gemcitabine and oxaliplatin/gemcitabine, respectively. Weighted median of mOS was 9.7 months in cisplatin group and 9.5 months in oxaliplatin group. Cisplatin-based chemotherapy was significantly associated with more grade 3 and 4 asthenia, diarrhea, liver toxicity, and hematological toxicity. Sensitivity analysis including only the studies with the standard regimen of cisplatin (25-35 mg/m(2) administered on days 1 and 8) showed that the weighted median of mOS increased from 9.7 to 11.7 months but Gem/CDDP regimen remained more toxic than Gemox regimen. These results suggest that the Gem/CDDP regimen with cisplatin (25-35 mg/m(2)) administered on days 1 and 8 is associated with survival advantage than Gemox regimen but with addition of toxicity., (© 2014 The Authors.

Goal: To study the impact of systemic treatment in neoadjuvant strategy before surgery in prostate cancer., Materials: Literature reviews with data analysis from PubMed search using the keywords "neoadjuvant", "chemotherapy", "hormonal therapy", "prostate surgery", "radical prostatectomy", but also reports from ASCO and ESMO conferences. The articles on neoadjuvant treatment before radiotherapy were excluded., Results: First studies with former therapy are more than 15-years-old and with questionable methodology: lack of power to have a clear idea of the impact on survival criteria such as overall survival or relapse-free survival. However, the impact of neoadjuvant hormone therapy on the classic risk factors for relapse (positive margins, intraprostatic disease, positive lymph nodes) was demonstrated by these studies and a Cochrane meta-analysis. The association with hormone therapy seems mandatory in comparison to treatment based solely on chemotherapy and/or targeted therapy. Promising data on the use of new drugs and their combinations arise: abiraterone acetate combined with LHRH analogue showed a fast PSA decrease and higher rates of pathologic complete response. Other results are promising with hormonal blockages at various key points., Conclusion: Studies with 2nd generation anti-androgene agents or enzyme inhibitors seem to show very promising results. To provide answers about the effectiveness of current neoadjuvant strategy in terms of survival, other studies are needed: randomized phase III or phase II exploring predictive biomarkers. The design of such trials requires a multidisciplinary approach with urologists, oncologists, radiologists and methodologists., (Copyright © 2014 Elsevier Masson SAS. All rights reserved.)

Introduction: The aim of this retrospective clinical study was to assess, in the context of the recent evolution of systemic therapies, the potential effect of targeted therapies on overall survival (OS) of patients with metastatic clear-cell renal cell carcinoma (mccRCC) in daily practice., Patients and Methods: All consecutive patients with histologically confirmed mccRCC who received systemic therapy between January 2000 and December 2010 in two oncology treatment centers in our Franche-Comté region in eastern France were included in the analysis. The primary end point was OS. The analysis of prognostic factors was performed using a two-step approach: univariate then multivariate analysis with a stepwise Cox proportional hazards regression model., Results: For the entire cohort of 111 patients, the median OS was 17 months (95% confidence interval [CI]; 13-22 months) and the two-year OS was 39%. Three prognostic factors were independent predictors of long survival: prior nephrectomy (hazard ratio =0.38 [0.22-0.64], P<0.0001); systemic therapy by targeted therapy (hazard ratio =0.50 [0.31-0.80], P=0.005); and lack of liver metastasis (hazard ratio =0.43 [0.22-0.82], P=0.002). Median OS was 21 months [14-29 months] for patients who received at least one targeted therapy compared with 12 months [7-15 months] for patients who were treated only by immunotherapy agents (P=0.003)., Conclusion: Our results suggest that targeted therapies are associated with improved OS in comparison with cytokines, which is in line with other publications.
