IMPORTANCE: Endometrial cancer is often hormone-dependent and treated with aromatase inhibitors. The PI3K-AKT-mTOR pathway deregulation observed in endometrial cancer drives hormonal resistance, thus supporting the rationale of combining mTOR inhibitor with endocrine therapy. OBJECTIVE: To evaluate the safety and efficacy of vistusertib in combination with anastrozole in the treatment of women with hormone receptor−positive recurrent or metastatic endometrial cancer. DESIGN, SETTINGS, AND PARTICIPANTS: The VICTORIA study was a multicenter, open-label, randomized clinical trial that accrued 75 patients with hormone receptor−positive recurrent or metastatic endometrial cancer from 12 cancer centers in France in April 2016 to October 2019. After a safety run-in period, a Simon 2-stage design was used. Data analyses were performed from December 11, 2020, to March 11, 2021. INTERVENTIONS: Patients were randomized in a 2:1 ratio to oral vistusertib (125 mg twice daily 2 days per week) and oral anastrozole (1 mg daily) in the combination vistusertib with anastrozole arm (V+A arm) or oral anastrozole alone (A arm). MAIN OUTCOMES AND MEASURES: The primary end point was serious adverse events for the safety run-in period and progression-free rate at 8 weeks (8wk-PFR)—assessed with a blinded independent central review in phase 2. The secondary end points were objective response rate, duration of response, progression-free survival (PFS), overall survival, and incidence of adverse events. RESULTS: Of the 75 patients who were randomized, 73 (median [range] age, 69.5 [37-88] y; all female) were treated: V+A arm, 49 patients; A arm, 24 patients. In the V+A arm, the 8wk-PFR was 67.3% (unilateral 95% CI, 54.7%) and in the A arm, 39.1% (unilateral 95% CI, 22.2%). No significant serious adverse events were reported during the safety run-in period (n = 6 in V+A arm). The overall response rate was 24.5% (95% CI, 13.3%-38.9%) in the V+A arm vs 17.4% (95% CI, 5.0%-38.8%) in the A arm. With a median follow-up of 27.7 months, median PFS was 5.2 (95% CI, 3.4-8.9) in the V+A arm and 1.9 (95% CI, 1.6-8.9) months in the A arm. Fatigue, lymphopenia, hyperglycemia, and diarrhea were the most common (grade ≥2) adverse events associated with vistusertib. CONCLUSIONS AND RELEVANCE: This multicenter, open-label, phase 1/2 randomized clinical trial demonstrated that adding vistusertib to anastrozole improved 8wk-PFR, overall response rate, and PFS for patients with endometrial cancer and had manageable adverse events. Identification of molecular subgroups would allow for more precise selection of patients who may be most likely to experience favorable outcomes.

Supervised exercise dietary programs are recommended to relieve cancer-related fatigue and weight increase induced by adjuvant treatment of early breast cancer (EBC). As this recommendation lacks a high level of evidence, we designed a multicenter randomized trial to evaluate the impact of an Adapted Physical Activity Diet (APAD) education program on fatigue. We randomized 360 women with EBC who were receiving adjuvant chemotherapy and radiotherapy to APAD or usual care at eight French cancer institutions. Data were collected at baseline, end of chemotherapy, end of radiotherapy, and 6 months post-treatment. The primary endpoint was the general cancer-related fatigue score using the MFI-20 questionnaire. Fatigue correlated with the level of precariousness, but we found no significant difference between the two groups in terms of general fatigue (p = 0.274). The APAD arm has a smaller proportion of patients with confirmed depression at the end of follow-up (p = 0.052). A transient modification in physical activity levels and dietary intake was reported in the experimental arm. However, a mixed hospital- and home-based APAD education program is not enough to improve fatigue caused by adjuvant treatment of EBC. Cancer care centers should consider integrating more proactive diet&ndash, exercise supportive care in this population, focusing on precarious patients.

Purpose Genomic tests can identify ER-positive HER2-negative localized breast cancer patients who may not benefit from adjuvant chemotherapy. Such tests seem especially interesting in “intermediate” clinico-pathological risk categories. The psychological impact of the decision uncertainty in these women remains largely unexplored. We assessed the clinical and psychological impact of EndoPredict® (EpClin), a clinico-genomic test, in these patients. Methods This multicenter, single arm prospective study (NCT02773004) enrolled patients for which adjuvant chemotherapy was uncertain, based on predefined criteria. The primary endpoint was the proportion of change between initial adjuvant decision and final administration of chemotherapy. Secondary endpoints included post-test (Day 17) and 1-year patient reported outcomes. Results One third of 200 evaluable patients had a high EpClin score (≥3.32867; 10 years cumulative risk of distance failure ≥10%). The overall change rate of chemotherapy decision was 72/200 (35.8%, 95% CI 29.2–42.4). Chemotherapy was withdrawn in 57 cases (28.4% [22.2–34.8]) and added in 15 (7.5% [3.8–11.2]. 6 changes (8%) were based on patients’ decisions. Anxiety and distress levels increased at Day 17 when adding chemotherapy after the test result (p, Highlights • EndoPredict ® (EpClin) allowed a chemotherapy decision modification in 35% of the patients included in the Adendom trial. • Patient-physician concertation is important: 8% of treatment changes are based on patients’ will. • A single-step decision including the test appears preferable to limit anxiety and distress.

Metastatic breast cancer (MBC) patients experience long survival and report poorer quality of life than localized breast cancer patients. Comprehensive supportive care (CSC) has been shown to improve the quality of life (QoL) of MBC. The respective part of each support care has not been fully examined, and little is known about whether meeting patients’ needs is accompanied by decreased unscheduled hospital care (UHC). This prospective monocentric study included women who started a new treatment line for MBC between January 2018 and December 2018. The endpoints were factors associated with UHC and QoL (SF36) at month 12. 100 patients were offered CSC, 78 were included (21 refusals, 1 no MBC). CSC was provided to 60 patients: pain (43%), psychological (37%), kinesitherapy (30%), social assistance (22%), esthetic (18%), nutrition (18%), massage (13%), and none (10%). CSC rate was not statistically different among patients with (58%) and without UHD (49%). Factors associated with a decrease of UHC were age > 65 years (p = 0.01), no previous treatment for MBC (p = 0.0001) with a trend for the lack of CSC (p = 0.054). Among the 8 domains of the SF36 scale, only health change perception was improved (p = 0.01) and its predictive factors were treatment carried out as planned (p = 0.0004), pain care (p = 0.003), and lack of MBC progression (p = 0.0035). CSC can improve QoL in MBC. Painful patients might benefit more from CSC. UHC did not decrease for patients receiving CSC as expected possibly because of their important needs for clinical care.

Background In early breast cancer (BC), there has been a trend to escalate endocrine therapy (ET) and to de-escalate chemotherapy (CT). However, the impact of ET versus CT on the quality of life (QoL) of early BC patients is unknown. Here, we characterize the independent contribution of ET and CT on patient-reported outcomes (PROs) at 2 years after diagnosis. Patients and methods We prospectively collected PROs in 4262 eligible patients using the European Organization for Research and Treatment of Cancer QLQ-C30/BR23 questionnaires inside CANTO trial (NCT01993498). The primary outcome was the C30 summary score (C30-SumSc) at 2 years after diagnosis. Results From eligible patients, 37.2% were premenopausal and 62.8% postmenopausal; 81.9% received ET and 52.8% CT. In the overall cohort, QoL worsened by 2 years after diagnosis in multiple functions and symptoms; exceptions included emotional function and future perspective, which improved over time. ET (Pint = 0.004), but not CT (Pint = 0.924), had a persistent negative impact on the C30-SumSc. In addition, ET negatively impacted role and social function, pain, insomnia, systemic therapy side-effects, breast symptoms and further limited emotional function and future perspective recovery. Although CT had no impact on the C30-SumSc at 2-years it was associated with deteriorated physical and cognitive function, dyspnea, financial difficulties, body image and breast symptoms. We found a differential effect of treatment by menopausal status; in premenopausal patients, CT, despite only a non-significant trend for deteriorated C30-SumSc (Pint = 0.100), was more frequently associated with QoL domains deterioration than ET, whereas in postmenopausal patients, ET was more frequently associated with QoL deterioration, namely using the C30-SumSc (Pint = 0.004). Conclusion(s) QoL deterioration persisted at 2 years after diagnosis with different trajectories by treatment received. ET, but not CT, had a major detrimental impact on C30-SumSc, especially in postmenopausal women. These findings highlight the need to properly select patients for adjuvant ET escalation.

International audience; Ameloblastomas are uncommon locally aggressive tumors of odontogenic epithelium that rarely metastasize. Currently, there is no standard of care for the metastatic forms. Several studies have shown that ameloblastomas frequently have a BRAF mutation.Case presentation: We report a case of a 33-year-old Caucasian woman with ameloblastoma diagnosed 30 years ago who developed lung metastasis 19 years ago. Systemic oral treatment with vemurafenib, a BRAF inhibitor, was initiated 28 months ago within the AcSé French basket clinical trial of vemurafenib.Conclusions: The patient has shown a durable clinical, functional, and radiographic partial response with vemurafenib. These observations suggest the possibility of introducing neoadjuvant and/or adjuvant targeted therapy in locally advanced ameloblastoma to improve outcome. BRAF inhibition has proved to be an efficient strategy in patients with a BRAF-mutated ameloblastoma.

Background In patients treated with cardiotoxic chemotherapies, the presence of cardiovascular risk factors and previous cardiac disease have been strongly correlated to the onset of cardiotoxicity. The influence of overweight and obesity as risk factors in the development of treatment-related cardiotoxicity in breast cancer (BC) was recently suggested. However, due to meta-analysis design, it was not possible to take into account associated cardiac risk factors or other classic risk factors for anthracycline (antineoplastic antibiotic) and trastuzumab (monoclonal antibody) cardiotoxicity. Methods and findings Using prospective data collected from 2012–2014 in the French national multicenter prospective CANTO (CANcer TOxicities) study of 26 French cancer centers, we aimed to examine the association of body mass index (BMI) and cardiotoxicity (defined as a reduction in left ventricular ejection fraction [LVEF] > 10 percentage points from baseline to LVEF < 50%). In total, 929 patients with stage I–III BC (mean age 52 ± 11 years, mean BMI 25.6 ± 5.1 kg/m2, 42% with 1 or more cardiovascular risk factors) treated with anthracycline (86% epirubicin, 7% doxorubicin) and/or trastuzumab (36%), with LVEF measurement at baseline and at least 1 assessment post-chemotherapy were eligible in this interim analysis. We analyzed associations between BMI and cardiotoxicity using multivariate logistic regression. At baseline, nearly 50% of the study population was overweight or obese. During a mean follow-up of 22 ± 2 months following treatment completion, cardiotoxicity occurred in 29 patients (3.2%). The obese group was more prone to cardiotoxicity than the normal-weight group (9/171 versus 8/466; p = 0.01). In multivariate analysis, obesity (odds ratio [OR] 3.02; 95% CI 1.10–8.25; p = 0.03) and administration of trastuzumab (OR 12.12; 95% CI 3.6–40.4; p < 0.001) were independently associated with cardiotoxicity. Selection bias and relatively short follow-up are potential limitations of this national multicenter observational cohort. Conclusions In BC patients, obesity appears to be associated with an important increase in risk-related cardiotoxicity (CANTO, ClinicalTrials.gov registry ID: NCT01993498). Trial registration ClinicalTrials.gov NCT01993498., Charles Guenancia and colleagues investigate the association of obesity to breast cancer treatment related cardiotoxicity., Author summary Why was this study done? Anthracyclines remain a cornerstone of breast cancer therapy, in combination with new-generation targeted drugs such as trastuzumab, and represent the major culprit in chemotherapy-induced heart disease. In a recent meta-analysis, we showed that overweight and obesity increased cardiotoxicity, but it was not possible to take into account associated cardiac risk factors or other classic risk factors for anthracycline and trastuzumab cardiotoxicity. We examined the association of body mass index (BMI) and cardiotoxicity using prospective data collected in the CANTO study, a French national cohort. What did the researchers do and find? In patients treated for stage I–III breast cancer with anthracyclines and/or trastuzumab, being obese was associated with increased risk of developing cardiotoxicity, regardless of other predictors of cardiotoxicity. Among all the classic risk factors for cardiotoxicity, overweight and obesity were by far the most common risk factors in this breast cancer population. What do these findings mean? Obesity appears to be a risk factor for cardiotoxicity in breast cancer patients. Overweight and obese patients may benefit from careful cardiac screening and follow-up during and after chemotherapy.

Since the last guidelines published by the French National Cancer Institute (INCa) and the learning society "Société française de sénologie et de pathologie mammaire (SFSPM)" in 2009 about diagnosis and management of ductal carcinoma in situ, new data raised issues about overdiagnosis and its consequences, overtreatment. Therefore, an update was necessary, to provide healthcare professionals up-to-date guidelines and study therapeutic desescalation in particular.The clinical practice guidelines development process is based on systematic literature review and critical appraisal by a multidisciplinary experts workgroup. The recommendations are thus based on the best available evidence and experts agreement. Prior to publication, the guidelines are also reviewed by more than 100 independent practitioners in cancer care delivery.This article presents French guidelines about MRI and vacuum assisted breast biopsy indications for DCIS diagnosis and the management of low-grade DCIS.

In case of a new breast symptom or an abnormal result of breast imaging, some women have a problem finding a quick answer to allay their anxiety. The Institut Sainte-Catherine in Avignon has set up a new form of accelerated disease management through the opening of a new dedicated consultation called SOS SEIN 84. We present the result of a prospective quality study of our first new patients.

A 35-year-old man had prolonged occupational exposure to lead carboxylate, triethylbenzene, xylene, and dichloromethane, when he developed a subacute predominantly sensory neuropathy. Ultrastructural examination of a peripheral nerve biopsy showed axonal degeneration and unusual lesions of the myelin, with Schwann cell sequestration of vesicular and lamellar debris. Biochemical analysis of lead in a frozen peripheral nerve specimen revealed no significant difference between the propositus and a control. The authors were unable to find any similar peripheral nerve lesions in the literature dealing with neurotoxic chemicals. Any of the several organic solvents could have equally caused the neuropathy and may have been potentialized by the other chemicals.

Prognostic signification of micrometastases ou isolated tumor cells (ITC) has not yet been clearly precised. Management of the axilla in case of micrometastases or ITC depends on the local pratices: no surgical completion or axillary lymph node dissection (ALND). Axillary lymph node status is the most important prognostic factor in patients with breast cancer; morbidity of ALND is now well known whereas its therapeutic benefit has not been demonstrated. This study is based on a retrospective database of 1375 patients who underwent sentinel node (SN) biopsy for breast cancer. In case of micrometastase or ITC in SN with completion axillary dissection, we examined if non-sentinel lymph node status has changed the indications of adjuvant treatments (chimiotherapy or radiotherapy). The results of our study show that non-sentinel lymph node status modify systemic therapy for a very few patients (less than 4% concerning chimiotherapy and less than 15% concerning radiotherapy).
