Background: In the PAOLA-1/ENGOT-ov25 primary analysis, maintenance olaparib plus bevacizumab demonstrated a significant progression-free survival (PFS) benefit in newly diagnosed advanced ovarian cancer patients in clinical response after first-line platinum-based chemotherapy plus bevacizumab, irrespective of surgical status. Prespecified, exploratory analyses by molecular biomarker status showed substantial benefit in patients with a BRCA1/BRCA2 mutation (BRCAm) or homologous recombination deficiency (HRD; BRCAm and/or genomic instability). We report the prespecified final overall survival (OS) analysis, including analyses by HRD status. Patients and methods: Patients were randomized 2: 1 to olaparib (300 mg twice daily; up to 24 months) plus bevacizumab (15 mg/kg every 3 weeks; 15 months total) or placebo plus bevacizumab. Analysis of OS, a key secondary endpoint in hierarchical testing, was planned for ∼60% maturity or 3 years after the primary analysis. Results: After median follow-up of 61.7 and 61.9 months in the olaparib and placebo arms, respectively, median OS was 56.5 versus 51.6 months in the intention-to-treat population [hazard ratio (HR) 0.92, 95% confidence interval (CI) 0.76-1.12; P = 0.4118]. Subsequent poly(ADP-ribose) polymerase inhibitor therapy was received by 105 (19.6%) olaparib patients versus 123 (45.7%) placebo patients. In the HRD-positive population, OS was longer with olaparib plus bevacizumab (HR 0.62, 95% CI 0.45-0.85; 5-year OS rate, 65.5% versus 48.4%); at 5 years, updated PFS also showed a higher proportion of olaparib plus bevacizumab patients without relapse (HR 0.41, 95% CI 0.32-0.54; 5-year PFS rate, 46.1% versus 19.2%). Myelodysplastic syndrome, acute myeloid leukemia, aplastic anemia, and new primary malignancy incidence remained low and balanced between arms. Conclusions: Olaparib plus bevacizumab provided clinically meaningful OS improvement for first-line patients with HRD-positive ovarian cancer. These prespecified exploratory analyses demonstrated improvement despite a high proportion of patients in the placebo arm receiving poly(ADP-ribose) polymerase inhibitors after progression, confirming the combination as one of the standards of care in this setting with the potential to enhance cure. in press

The impact of single-agent antibodies against programmed death-ligand 1 (PD-L1) as maintenance therapy is unknown in patients with metastatic breast cancer. The SAFIR02-BREAST IMMUNO substudy included patients with human epidermal growth factor receptor type 2 (Her2)-negative metastatic breast cancer whose disease did not progress after six to eight cycles of chemotherapy. Patients (n = 199) were randomized to either durvalumab (10 mg kg−1 every 2 weeks) or maintenance chemotherapy. In the overall population, durvalumab did not improve progression-free survival (adjusted hazard ratio (HR): 1.40, 95% confidence interval (CI): 1.00–1.96; P = 0.047) or overall survival (OS; adjusted HR: 0.84, 95% CI: 0.54–1.29; P = 0.423). In an exploratory subgroup analysis, durvalumab improved OS in patients with triple-negative breast cancer (TNBC; n = 82; HR: 0.54, 95% CI: 0.30–0.97, P = 0.0377). Exploratory analysis showed that the HR of death was 0.37 (95% CI: 0.12–1.13) for patients with PD-L1+ TNBC (n = 32) and 0.49 (95% CI: 0.18–1.34) for those with PD-L1− TNBC (n = 29). In patients with TNBC, exploratory analyses showed that the HR for durvalumab efficacy (OS) was 0.18 (95% CI: 0.05–0.71; log-rank test, P = 0.0059) in patients with CD274 gain/amplification (n = 23) and 1.12 (95% CI: 0.42–2.99; log-rank test, P = 0.8139) in patients with CD274 normal/loss (n = 32). Tumor infiltration by lymphocytes (CD8, FoxP3 and CD103 expressions) and homologous recombination deficiency did not predict sensitivity to durvalumab in exploratory analyses. This latter finding should be interpreted with caution since only one patient presented a germline BRCA mutation. The present study provides a rationale to evaluate single-agent durvalumab in maintenance therapy in patients with TNBC. Exploratory analyses identified CD274 amplification as a potential biomarker of sensitivity. Maintenance chemotherapy was more effective than durvalumab in patients with hormone receptor-positive and Her2-negative disease. Exploratory analyses from the phase 2 randomized SAFIR02-IMMUNO trial identify biomarkers associated with improved outcomes to durvalumab as compared to maintenance chemotherapy in patients with triple-negative breast cancer.

Small cell carcinoma of the ovary of hypercalcemic type (SCCOHT) is a rare and rapidly lethal disease affecting young women. Cytoreductive surgery associated with chemotherapy followed by a high dose chemotherapy regimen (HDC) demonstrated improved outcomes in a unique prospective and several retrospective studies, and this report aimed to confirm these results in an independent and larger cohort.Between 2006 and 2018, we conducted a multicentric prospective study on 44 women diagnosed with SCCOHT. Patients were treated homogeneously with optimal cytoreductive surgery and chemotherapy protocol for four to six cycles (PAVEP). In case of complete response, patients received HDC with stem-cell support, followed by pelvic radiotherapy. The primary endpoint was the event-free survival (EFS) in the per-protocol cohort. Secondary analysis explored the effect of HDC with outcomes.Mean age at diagnosis was 33 years old (range 13.8-75.8). 14 patients presented with stage FIGO I, 21 with stage III and 9 with stage IV. Median follow-up was 53.4 months. 38 patients underwent optimal surgery with up to 6 cycles of PAVEP. 30 received HDC, and 21 pelvic radiotherapy. 21 relapses were reported leading to death for 18 patients. Median EFS in the per-protocol cohort was 18.2 months, and 2-year EFS rate was 40%. HDC was significantly associated with better overall survival (p .001). Grades 3/4 adverse events were frequent but, in most cases, manageable, although one grade-5 adverse-event occurred during HDC.Intensive regimen containing multidrug chemotherapy, HDC and pelvic radiotherapy, for the management of SCCOHT, demonstrated encouraging survival and should be proposed for all patients. However, the significant toxicity cost associated is of concern and it should be restricted to expert centers.

Background: Prognosis of women with HER2+ metastatic breast cancer (MBC) has radically improved over the past 10 years, resulting from the implementation in clinical of anti-HER2 therapies. However, there are limited data regarding these trends in the older women, although they represent a growing segment of the population. Standard strategy being based mostly on combinations of anti-HER2 treatments with chemotherapy, under-treatment may be a specific issue in this population. Methods: Based on the ESME MBC Data Platform (NCT03275311),a unique national real-life database including individual data from all patients (pts) ≥18 years who initiated a first-line treatment for MBC between 2008 and 2016 in the 18 French Comprehensive Cancer Centers, the main objective of this work was the description of patients’ outcome in women with HER2+ MBC according to age: ≥70 vs Results: Of 22463 cases selected, 4045 (18%) women had HER2+ MBC with a 4.4-year median follow-up. Of those, 814 (20%) were aged ≥ 70 and had more often HR+ disease (Table 1). As 1st line treatment, anti-HER2 therapy was prescribed in 76% vs 92% of older vs younger pts, combined with chemotherapy in 65% vs 89%. Median OS and PFS (years) were 2.9 [2.6-3.1] and 0.9 [0.8 - 1.0] vs 4.5 [4.2-4.6] and 1.1 [1.1-1.2] in older vs younger patients. Multivariate analysis for OS identified the following variables as significant: age ≥ 70 (HR=1.57 IC95% [1.40-1.75]), 2 and ≥ 3 metastatic sites (HR=1.24 IC95% [1.10-1.39] and HR=1.92 IC95% [1.70-2.17] respectively), de novo MBC (HR 0.70 IC95% [0.63 - 0.77]), visceral disease with a time-varying effect (HR=2.67 IC95% [2.11-3.39] and 5.98 IC95% [4.64-7.46] at 1 and 5 years) and first-line treatment with a time-varying effect, better prognosis for combination of chemotherapy + anti-HER2 agent + endocrine therapy vs any other. Except for de novo MBC, similar results were observed for PFS. Conclusions: In this large real-life database, older HER2+ MBC patients received significantly less frequently “standard” first-line anti-HER2 treatment, defined as a combination of chemotherapy and anti-HER2 treatment. Age was a strong risk factor for both PFS and OS. Given the lack of information on geriatric assessment (e.g. general health status, functional status, comorbidity, etc.), confounding factors and usual selection biases cannot be ruled out. These results stress the importance to study older populations with specific approaches, not based on the usual transfer of those developed in younger ones, in order to avoid under and overtreatments, both that are not acceptable.

With the approval of new therapies targeting the PI3K pathway, the detection of PIK3CA mutations has become a key factor in treatment management for HR+/HER2− metastatic breast cancer (MBC). We developed multiplex digital PCR (dPCR) assays to detect and quantify PIK3CA mutations. A first screening assay allows the detection of 21 mutations, with a drop-off system targeting the 542–546 hotspot mutations combined with the simultaneous detection of N345K, C420R, H1047L and H1047R mutations. In the case of a positive result, a sequential strategy based on other assays that we have developped allows for precise mutation identification. Clinical validity was determined by analyzing plasma circulating free DNA (cfDNA) from 213 HR+/HER2− MBC samples, as well as DNA extracted from 97 available matched tumors from 89 patients. Our assays have shown reliable specificity, accuracy and reproducibility, with limits of blank of three and four droplets for the screening assay. Sixty-eight patients (32%) had at least one PIK3CA mutation detectable in their plasma, and we obtained 83.1% agreement between the cfDNA analysis and the corresponding tumors. The high sensitivity and robustness of these new dPCR assays make them well-suited for rapid and cost-effective detection of PIK3CA mutations in the plasma of MBC patients.

Purpose: Genomic signatures, such as EndoPredict®, may help clinicians to decide which adjuvant treatment is the most appropriate. Methods: We propose the EndoPredict® assay for unclear cases of adjuvant treatment in patients treated in our comprehensive cancer center. We prospectively and retrospectively report the decision of adjuvant treatment before and after the EndoPredict® assay, respectively, compared to the PREDICT’s tool scores. Results: From November 2016 to March 2019, 159 breast cancer tumors were analyzed and presented before and after the EndoPredict® assay. Before the EndoPredict® results, clinicians recommended chemotherapy for 57 patients (57/159, 36%). A total of 108 patients (108/159, 68%) were classified as EPclin high-risk score. There was only a slight agreement between clinicians’ decisions and EPclin risk score. The EPclin score led to 37% changes in treatment (59/159); chemotherapy was favored in 80% of cases (47/59). The PREDICT tool recommended chemotherapy for 16 high-risk patients (16/159, 10%). Conclusion: Although genomic tests were developed in order to de-escalate adjuvant treatment, in our comprehensive cancer center the use of the EndoPredict® assay led to an increase in prescribed chemotherapy.

Background Leptomeningeal metastasis (LM) is a rare complication of metastatic breast cancer (MBC), with high morbidity/mortality rates. Our study aimed to describe the largest-to-date real-life population of MBC patients treated with intrathecal (IT) therapy and to evaluate prognostic models. Methods The Epidemiological Strategy and Medical Economics (ESME) MBC database (NCT03275311) includes all consecutive patients who have initiated treatment for MBC since 2008. Overall survival (OS) of patients treated with IT therapy was estimated using the Kaplan–Meier method. Prognostic models were constructed using Cox proportional hazards models. Performance was evaluated using C-index and calibration plots. Results Of the 22 266 patients included in the database between 2008 and 2016, 312 received IT therapy and were selected for our analysis. Compared with non-IT-treated patients, IT-treated patients were younger at MBC relapse (median age: 52 years versus 61 years) and more often had lobular histology (23.4% versus 12.7%) or triple-negative subtype (24.7% versus 13.3%) (all P < 0.001). Median OS was 4.5 months [95% confidence interval (CI) 3.8-5.6] and 1-year survival rate was 25.6%. Significant prognostic factors associated with poorer outcome on multivariable analysis were triple-negative subtype (hazard ratio 1.81, 95% CI 1.32-2.47), treatment line ≥3 (hazard ratio 1.88, 95% CI 1.30-2.73), ≥3 other metastatic sites (hazard ratio 1.33, 95% CI 1.01-1.74) and IT cytarabine or thiotepa versus methotrexate (hazard ratio 1.68, 95% CI 1.28-2.22), while concomitant systemic therapy was associated with better OS (hazard ratio 0.47, 95% CI 0.35-0.62) (all P < 0.001). We validated two previously published prognostic scores, the Curie score and the Breast-graded prognostic assessment, both with C-index of 0.57. Conclusions MBC patients with LM treated with IT therapy have a poor prognosis. We could identify a subgroup of patients with better prognosis, when concomitant systemic therapy and IT methotrexate were used., Highlights • The outcome of BC patients with IT-treated LM is poor, with a median OS of 4.5 months. • Concomitant systemic therapy may improve the outcome in IT-treated patients. • Patients treated with IT methotrexate had better outcome than those treated with IT cytarabine/thiotepa. • The Curie and Breast-graded prognostic assessment scores were prognostic for IT-treated patients.

Background: Breast cancer is the most frequent form of cancer in young women. For these patients, breast cancer is generally more aggressive and chemotherapy is more often needed. Chemotherapy is commonly associated with amenorrhea and a decrease of ovarian reserve depending on the patient's age, agents and dose. Embryo, oocyte and ovarian tissue cryopreservation are the three options to preserve fertility. Embryo and oocyte cryopreservation require controlled ovarian stimulation (COS). The use of COS is associated with an increase of estradiol levels. It led to develop protocols using Tamoxifen or Letrozole combined with FSH to protect patients of the potential deleterious effects of the COS. PRESAGE is the first French prospective multicenter feasibility study about fertility preservation by COS combined with Tamoxifen and oocyte +/- embryo cryopreservation before neoadjuvant (NAC) or adjuvant (AC) chemotherapy for breast cancer. Material and method: Prospective multicenter study for patients of less than 40 years, with a breast cancer, for whom a treatment of NAC or AC is indicated and who wish to preserve their fertility. The main objective was to evaluate the feasibility of a COS associating Tamoxifen with FSH followed by an oocyte+/- embryo cryopreservation. The secondary objectives were to evaluate the average deadline prior to the beginning of the chemotherapy and the impact of the type of COS (depending on the phase of the menstrual cycle, conventional-start or random-start COS protocol) on the number and the quality of oocytes harvested. Statistical analysis was performed using SAS statistical software version 9.4 (SAS Institute, Cary, NC). Results: 101 patients were included between February 2014 and July 2017 and 97 patients were eligible for statistical analysis. Mean age of the patients was 31,5 +/- 4 years, the half of them was nulliparous (53/97) and 23,7 % (23/97) were single. They presented mainly SBR II or III (91/96, 94,8 %) lesions, ER + (66/96, 68,7 %). 38 patients benefited from a NAC and 59 of an AC. We have found a significant shorter care (time between the first oncologist's consultation and the beginning of the chemotherapy) according to the type of chemotherapy: 29,7 +/- 15,6 days in NAC group vs 45,2 +/- 21,5 days in AC group (p=0,003) with the same duration of ovarian stimulation in the two groups (10,5 +/-2 days). The success rate of the COS procedure was 90,7 % (88/97) with no significant difference between the groups according to the type of COS (p = 0.06) or the type of chemotherapy (AC vs. NAC p= 0,3). In the 88 patients who had oocyte retrieval, the number of oocytes harvested per patient was 12,8 +/- 7,8 , the number of oocytes preserved was 9,7 +/- 6,1 and an IVF was performed in 12,5% of patients (11/88) with 5,1 +/- 3,1 embryos obtained. We have found no impact of the type of chemotherapy or the type of COS on the number of oocytes or embryos preserved. Conclusion: with a high success rate (90,7%), our study suggests that COS with Tamoxifen and FSH is feasible before adjuvant or neoadjuvant chemotherapy in breast cancer patients. We also show that COS procedure before neoadjuvant chemotherapy can be realized without increasing the time before introducing chemotherapy.

Background Neurokinin (NK) 1 receptor antagonists (RAs), administered in combination with a 5‐hydroxytryptamine‐3 (5‐HT3) RA and dexamethasone (DEX), have demonstrated clear improvements in chemotherapy‐induced nausea and vomiting (CINV) prevention over a 5‐HT3RA plus DEX. However, studies comparing the NK1RAs in the class are lacking. A fixed combination of a highly selective NK1RA, netupitant, and the 5‐HT3RA, palonosetron (NEPA), simultaneously targets two critical antiemetic pathways, thereby offering a simple convenient antiemetic with long‐lasting protection from CINV. This study is the first head‐to‐head NK1RA comparative study in patients receiving anthracycline cyclophosphamide (AC) and non‐AC moderately emetogenic chemotherapy (MEC). Materials and Methods This was a pragmatic, multicenter, randomized, single‐cycle, open‐label, prospective study designed to demonstrate noninferiority of single‐dose NEPA to a 3‐day aprepitant regimen in preventing CINV in chemotherapy‐naive patients receiving AC/non‐AC MEC in a real‐life setting. The primary efficacy endpoint was complete response (no emesis/no rescue) during the overall (0–120 hour) phase. Noninferiority was achieved if the lower limit of the 95% confidence interval (CI) of the difference between NEPA and the aprepitant group was greater than the noninferiority margin set at −10%. Results Noninferiority of NEPA versus aprepitant was demonstrated (risk difference 9.2%; 95% CI, −2.3% to 20.7%); the overall complete response rate was numerically higher for NEPA (64.9%) than aprepitant (54.1%). Secondary endpoints also revealed numerically higher rates for NEPA than aprepitant. Conclusion This pragmatic study in patients with cancer receiving AC and non‐AC MEC revealed that a single dose of oral NEPA plus DEX was at least as effective as a 3‐day aprepitant regimen, with indication of a potential efficacy benefit for NEPA. Implications for Practice In the absence of comparative neurokinin 1 (NK1) receptor antagonist (RA) studies, guideline committees and clinicians consider NK1RA agents to be interchangeable and equivalent. This is the first head‐to‐head study comparing one NK1RA (oral netupitant/palonosetron [NEPA]) versus another (aprepitant) in patients receiving anthracycline cyclophosphamide (AC) and non‐AC moderately emetogenic chemotherapy. Noninferiority of NEPA versus the aprepitant regimen was demonstrated; the overall complete response (no emesis and no rescue use) rate was numerically higher for NEPA (65%) than aprepitant (54%). As a single‐dose combination antiemetic, NEPA not only simplifies dosing but may offer a potential efficacy benefit over the current standard‐of‐care., Guidelines suggest that NK1RA agents are interchangeable. This article reports the first study comparing one NK1RA (oral NEPA [netupitant/palonosetron]) with another (aprepitant) in patients receiving chemotherapy.

Background Currently, oral targeted therapies are known to be effective and are frequently used to treat metastatic cancer patients, but fatigue is a frequently reported early side effect of these treatments. This fatigue may impact the patient’s treatment adherence and result in a negative impact on quality of life. Physical exercise significantly improved the general well-being and quality of life of advanced cancer patients. However, there is no specific physical activity program adapted for patients with advanced disease. Methods QUALIOR is a two-part, randomized, open-label, and multicenter with two arms phase II/III trial. Patients (phase II: n = 120; phase III: n = 312) with metastatic cancer (breast cancer, kidney cancer, lung cancer, and other cancers [including but not limited to colon cancer, melanoma, sarcoma, or hepatocarcinoma]) treated with a first- or second-line oral targeted therapy without chemotherapy will be included. Patients will be randomized (2:1) to a 3-month supervised home-based standardized physical activity program or to a recommended adapted physical activity (via a booklet). The primary objective of the phase II is to evaluate the feasibility of the supervised program. The primary objective of the phase III is the evaluation of the benefit of the supervised home-based program compare to the recommended program in terms of fatigue and quality of life at 3 months. The secondary objectives aim to evaluate the impact of the supervised program on fatigue over time, pain, physical capacities, psychosocial and cognitive functions, general quality of life, frequency of dose reduction and patients’ adherence to the targeted therapy, overall survival, and progression-free survival. This study will also evaluate the medico-economic impact of supervised program compared to the recommended adapted physical activity program. Discussion The aim of this study is to evaluate home-based physical exercise program for metastatic cancer patients treated with oral targeted therapies to help patients to cope with fatigue and improve quality of life. Trial registration This trial was registered in ClinicalTrials.gov since May 2017 (NCT03169075).

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.

Aim Real-world data inform the outcome comparisons and help the development of new therapeutic strategies. To this end, we aimed to describe the full characteristics and outcomes in the Epidemiological Strategy and Medical Economics (ESME) cohort, a large national contemporary observational database of patients with metastatic breast cancer (MBC). Methods Women aged ≥18 years with newly diagnosed MBC and who initiated MBC treatment between January 2008 and December 2016 in one of the 18 French Comprehensive Cancer Centers (N = 22,109) were included. We assessed the full patients’ characteristics, first-line treatments, overall survival (OS) and first-line progression-free survival, as well as updated prognostic factors in the whole cohort and among the 3 major subtypes: hormone receptor positive and HER2-negative (HR+/HER2−, n = 13,656), HER2-positive (HER2+, n = 4017) and triple-negative (n = 2963) tumours. Results The median OS of the whole cohort was 39.5 months (95% confidence interval [CI], 38.7–40.3). Five-year OS was 33.8%. OS differed significantly between the 3 subtypes (p Conclusions The ESME program represents a unique large-scale real-life cohort on MBC. This study highlights important situations of high medical need within MBC patients. Database registration clinicaltrials.gov Identifier NCT032753.

Introduction/Background Surgery is the cornerstone of ovarian Granulosa Cell Tumor (GCT). Complete resection with adequate staging is the gold standard in 1st line setting. The aim of this study is to assess the impact of an appropriate surgery according to the guidelines. Methodology This is a nationwide five-year retrospective study, including 463 patients (of the 639 included patients) with a definitive diagnosis of GCT between 2011 and 2016. Medical and surgical practices were analyzed for conformity. Conformity to guidelines was defined by a conservative (unilateral salpingo-oophorectomy) or radical surgery (hysteretomy and bilateral salpingo-oophorectomy) including surgical staging (omentectomy, peritoneal biopsy and peritoneal cytology) according to the FIGO classification. Results Median age at diagnosis was 49 years old (range 10–89). The median size of tumor was 94 mm (range 5–400). Radical surgery was performed in 240 patients (51,8%), while a fertility-sparing surgery was performed in 98 cases (21,2%). A complete surgical staging was performed in only 76 cases (16,4%). 289 (62.4%) patients received an evaluation of the endometrium (hysterectomy or endometrial curettage). Surgery was fully compliant with the guidelines in 65 patients (14%), partially compliant in 213 patients (46%), non-compliant in 137 patients (29,6%) and not assessable in 48 cases (10,4%) respectively. A statistically significant improvement in the surgical management was observed among patients treated after 2012 compared to those treated before 2012. This Improvement included: endometrial evaluation (p=0,026), tumour rupture rate during surgery (p=0,010) and the global compliance of the surgery (p Conclusion Staging surgery provides a better assessment and an appropriate treatment of this rare tumors. According to this study, the implementation of a national network and guidelines dedicated to rare gynaecologic tumors seems to significantly improve the surgical management of the patients with GCT.

Background: Breast cancer is the most frequent form of cancer for young women. For these patients, breast cancer is generally more aggressive and chemotherapy is more often needed. Chemotherapy is commonly associated with amenorrhea and a decrease of ovarian reserve depending on the patient's age, agents and dose. There are no guidelines to prevent subfertility for young women on cytotoxic treatments. Embryo, oocyte and ovarian tissue cryopreservation are the three options to preserve fertility. Embryo and oocyte cryopreservation require controlled ovarian stimulation (COS). The use of COS is associated with an increase of estradiol levels. It led to develop protocols using Tamoxifene or Letrozole combined with FSH to protect patients of the potential deleterious effects of the COS. We are currently conducting a study: PRESAGE, the first French prospective multicenter feasibility study of fertility preservation by COS combined with Tamoxifene and oocyte +/- embryo cryopreservation before neoadjuvant (NAC) or adjuvant (AC) chemotherapy for breast cancer. Material and method: Prospective multicenter study for patients of less than 40 years, with a breast cancer for whom a treatment of NAC or AC is indicated and who wish to preserve their fertility. The main objective: To evaluate the feasibility of a COS associating Tamoxifène with FSH followed by an oocyte more and less embryo cryopreservation. The secondary objectives: evaluation of the average deadline prior to the beginning of the chemotherapy, the impact of the type of COS (depending on the phase of the menstrual cycle, conventional-start or random-start COS protocol) on the number and the quality of oocytes harvested. Statistical analysis was performed using BiostaTGV software. Results: The 50 first patients were included between February 2014 and May 2016. Mean age of the patients was 31 years, half of it was nulliparous (25/50) and 20 % (10/50) were single. They presented mainly SBR II (23/50, 46 %) or III (25/50, 50 %) lesions, ER + (34/50, 68 %). 13 patients benefited from a NAC and 37 of an AC. In the NAC group, the time between the first oncologist's consultation and the fertility specialist's consultation was 3,5 +/- 3,9 days and the time between the first oncologist's consultation and the beginning of the chemotherapy was 24,5 +/- 6 days. The success rate of the COS procedure was 88 % (44/50) with no significant difference between the groups according to the type of COS (conventional-start vs. random-start p = 0.61) but there was a significant difference according to the type of chemotherapy (AC vs. NAC p= 0,03). In the 44 patients who had oocyte retrieval, the number of oocytes was 11,6 +/- 6,3 and an IVF was performed with 11,3% of patients (5/44) with 5,4 +/- 4,6 embryos obtained. We have found no impact of the type of chemotherapy or the type of COS on the number of oocytes or embryos preserved. Conclusion: with an 88% success rate, our study suggests that COS with Tamoxifene and FSH is feasible before adjuvant or neoadjuvant chemotherapy with less success in this context but without any impact on the number of oocytes collected. We hope that these preliminary results will be confirmed at the end of the study.

Background: The management of HER2+ BC has changed dramatically with the introduction and widespread use of HER2-targeted therapies, especially in the adjuvant setting. However, there is relatively limited real-world information on the impact of adjuvant Trastuzumab (aT) on patterns of recurrence and outcome of HER2+ MBC. Methods: In 2014, the 18 French Cancer Centers launched the Epidemiological Strategy and Medical Economics (ESME) program to provide real-world data on MBC patients (pts). All pts who started a 1st-line treatment for MBC between 01-Jan-2008 and 31-Dec-2014 were included. We examined clinical characteristics and outcomes (overall survival [OS] and time to next treatment [TNT]) in patients with HER2+ MBC pretreated with trastuzumab in the adjuvant setting (aT) compared with trastuzumab-naïve patients (nT) and patients with de novo HER2+ MBC (dn). Multivariate analyses adjusted for baseline demographic, prognostic factors and year of diagnosis (prior or after 2005, when aT was approved and widely administered in France for early HER2+ breast cancer). Results: Among the 15170 pts of the ESME database, 2863 (19%) were HER2+: 1093 pts (38%) had de novo and 1765 pts (62%) recurrent MBC; 63% were Hormone Receptor (HR) +; 54%, 25% and 21% had respectively 1, 2, or > 2 metastatic sites (68% visceral and 12% brain). Median time to 1st metastasis was 43.4 months (m) (95% CI: 24.6-84.4): 54 m in HR+ and 30 m in HR-. Among pts with recurrent MBC, 55% (995) had received aT. As 1st-line therapy for MBC, 90 % of pts received HER2-targeted agents (73% T-based). With a median follow-up of 46 m, median OS is 45 m (95% CI: 42.5-48). OS is significantly higher in de novo compared to recurrent MBC: 54 m (95% CI: 50.2-60.4) vs. 38.4 m (95% CI: 36.7-41.9), (p < 0.0001). Among pts with recurrent cancers, median OS is inferior in pts who had received aT, as compared to those who had not: 33.4 m (95% CI: 29.6-36.7) vs. 49.5 m (95% CI: 44.3-56.8), (p < 0.0001). Statistically significant differences persist after adjustment for age at MBC, disease-free interval, metastatic sites and RH status in the multivariate model (HR=1.45, 95% CI: 1.26-1.67) but not after adjustment for year of diagnosis (prior or after 2005) (HR=0.90, 95% CI: 0.70-1.15). Conclusions: These large-scale real-world data in patients with HER2+ MBC provide evidence that the survival outcome remain similar in patients with failure of adjuvant trastuzumab compared with trastuzumab-naïve patients after adjustment for year of diagnosis. De novo HER2+ MBC pts have the best outcomes. Data on clinical characteristics of metastasis and time to next treatment for the three subgroups will be presented at the meeting.

Objectives: In the PAOLA-1/ENGOT-ov25 primary analysis (NCT02477644), adding the PARP inhibitor olaparib to maintenance bevacizumab (bev) after first-line platinum-based chemotherapy with bev led to a significant progression-free survival (PFS) benefit vs placebo (pbo) + bev in patients (pts) with advanced high-grade ovarian cancer (HGOC), using modified RECIST v1.1 criteria (HR 0.59; 95% CI 0.49-0.72; P Methods: Pts with newly diagnosed, FIGO stage III-IV HGOC in response after platinum-based chemotherapy plus bev received bev (15 mg/kg q3w for 15 months) + olaparib (300 mg bid for 24 months) or pbo. Scans were performed every 24 weeks, or every 12 weeks if there was evidence of clinical or CA-125 progression. CA-125 levels were assessed every 12 weeks. Time to RECIST or CA-125 progression or death was a secondary endpoint; RECIST/CA-125 progression by biomarker status, response to initial therapy and CA-125 level at baseline were explored. Results: 537 pts were randomized to olaparib + bev and 269 to pbo + bev with median follow-up for PFS by RECIST/CA-125 of 24.2 vs 24.7 months (DCO 22 March 2019). In the ITT population, the benefit provided by olaparib + bev vs pbo + bev for PFS by RECIST/CA-125 (HR 0.58; 95% CI 0.48-0.70; P Download : Download high-res image (258KB) Download : Download full-size image Conclusions: Median PFS and HRs were consistent when progression was assessed by either RECIST or RECIST/CA-125 in PAOLA-1. Scans appear particularly important for detecting progression in HRD-positive pts, tBRCAm pts or pts with normal CA-125 levels at baseline as CA-125 levels did not seem to predict relapse in these pts. Results suggest that CA-125 surveillance alone may be sufficient to detect progression in most pts with abnormal baseline CA-125 levels when starting maintenance therapy.

5514 Background: In the Phase III PAOLA-1/ENGOT-ov25 trial (NCT02477644), the addition of maintenance olaparib to bev in pts with newly diagnosed advanced high-grade ovarian cancer (HGOC) resulted in a significant PFS benefit, particularly in HRD-positive (HRD+) pts (hazard ratio [HR] 0.33; 95% CI 0.25–0.45) (Ray-Coquard et al. NEJM 2019). We explored efficacy in HRD+ pts by disease stage. Methods: Pts with newly diagnosed, FIGO stage III–IV HGOC in response after platinum-based chemotherapy + bev received bev (15 mg/kg q3w for 15 months [mo]) + either olaparib (300 mg bid for 24 mo) or placebo (pbo). This exploratory analysis evaluated PFS (data cut-off [DCO]: Mar 22 2019) and PFS2 (DCO: Mar 22 2020) in HRD+ pts (tumor BRCA1/ BRCA2 mutation [tBRCAm] or genomic instability score [Myriad myChoice HRD Plus] ≥42) by FIGO stage. Results: 387/806 randomized pts (48%) were HRD+; 272/387 (70%) had stage III disease and 115/387 (30%) had stage IV disease. 153 (56%) HRD+ stage III pts and 61 (53%) HRD+ stage IV pts had a tBRCAm. Among HRD+ stage III pts, 172 (63%) had upfront surgery (51/172 [30%] had residual disease) and 90 (33%) had interval surgery (19/90 [21%] had residual disease); 52 (45%) HRD+ stage IV pts had upfront surgery (34/52 [65%] had residual disease) and 55 (48%) had interval surgery (18/55 [33%] had residual disease). Median follow-up for PFS and PFS2 was respectively 24.8 and 37.2 mo in HRD+ stage III pts and 24.0 and 37.0 mo in HRD+ stage IV pts. Median PFS, PFS2 and HRs are in the Table. Among HRD+ stage III pts, 36-mo PFS2 (olaparib + bev vs pbo + bev) was 74% vs 60%; among HRD+ stage IV pts, 53% vs 30%. Among HRD+ stage III pts with no residual disease after upfront surgery, HR (95% CI) for PFS was 0.15 (0.07–0.30) and for PFS2 was 0.22 (0.06–0.67). Among HRD+ stage III pts with residual disease after upfront surgery or who received neoadjuvant chemotherapy, or HRD+ stage IV pts, HR (95% CI) for PFS was 0.38 (0.27–0.53) and PFS2 was 0.68 (0.46–1.03). Conclusions: In the PAOLA-1 study, maintenance olaparib + bev provided a PFS and PFS2 benefit over pbo + bev in HRD+ pts, irrespective of FIGO stage and residual disease after upfront surgery. Clinical trial information: NCT02477644. [Table: see text]

Background A genomic-driven therapeutic strategy in metastatic breast cancer (MBC) was recently demonstrated as feasible in the clinical practice, but its actual impact on patient outcome remains elusive. SAFIR02 study is an ongoing national multicentric phase II randomized trial evaluating targeted therapies matching specific genomic alterations (GA) administered as maintenance after objective response and/or stable disease obtained with chemotherapy in HER2-negative MBC patients. This analysis reports on feasibility of the procedure and the rate of identified actionable targets. Methods Eligible MBC patients (PS=0/1, first- or second-line of chemotherapy, HER2-negative/hormone receptor (HR)-negative or endocrine resistant HR-positive; measurable per RECIST 1.1; accessible to tumor biopsy; no bone metastases-only disease, no major organ dysfunction) were subjected to tumor biopsy for genomic analysis (CGH arrays, Affymetrix Cytoscan; NGS, Ion Torrent PGM, AmpliSeq, panel of around 50 genes). Actionable GA were identified and corresponding targeted therapies were proposed by a multidisciplinary tumor board (MTB). Patients received cytotoxic-based treatment at physician's choice and those with stable or responding disease after 6 to 8 cycles (or at least 4 if stopped for toxicity reason) and targetable GA, were offered randomization between targeted therapy or chemotherapy maintenance until progression or intolerance (main study). Since January 2016, an amendment was made to propose to patients without targetable alteration a randomization between anti-PD-L1 (MEDI4736) or standard chemotherapy maintenance (substudy). Results Between March 2014 and May 2016, 457 patients have been enrolled at 21 centers. Genomic analyses could not be obtained in 107 cases (23%) due to either biopsy failure (n= 40; 9%) or low cellularity (n=67; 14%). Of the 307 patients reviewed by the MTB, 197 (64%) had an actionable GA, including PIK3CA-PIK3CB-PIK3R1 (n=51), FGF4 or FGFR1/2 (n= 42), BRCA1/2 (n=15), AKT1/2/3 (n=13), BRAF/KRAS/NRAS (n=13), HER2/3 (n=10), NF1-FRS2 (n=10), MTOR-RPTOR-TSC2 (n=8), PTEN (n=7), STK11 (n=7), IGF1R (n=7), EGFR (n=5). Therapeutic proposals by MTB included AZD5363 (n=71), AZD4547 (n=42), AZD2014 (n=23), selumetinib (n=23), olaparib (n=16), AZD8931 (n=15), vandetanib (n=5), bicalutamide (n=2). In an exploratory analysis involving 157 patients, the rate of targeted therapy proposal by MTB markedly differed between triple-negative patients (TNBC; 24 of 48, 50%) and HER2-negative/HR-positive patients (92 of 109, 84%; p=6.14. 10-6, Chi-2 test). At the time of the analysis, 85 patients have been randomized (main study, 68; substudy, 17). Causes of randomization failure (n=108) included disease progression (n=45) or death (n=25), non-eligibility criteria (n=27), patient/physician's decision (n=11). Conclusion A large number of patients had identified targetable GA. Of note, the rate of targeted therapeutic proposal was significantly lower in TNBC than in HER2-negative/HR-positive patients. Rapidly progressing disease may impede ultimate randomization.

The French national rare gynecological tumor network has been established to improve the quality of care through offering expertise in double reading histological diagnosis, reviewing cases and guiding management of these tumors through specialized multidisciplinary tumor boards and online clinical guidelines (www.ovaire-rare.com). The aim of this study is to evaluate the impact of the development and implementation of this network by assessing the conformity of medical practice with the guidelines concerning the granulosa cell tumors (GCTs).This is a French nationwide study, including 463 patients (out of the 639 identified patients) with a definitive diagnosis of GCT between 2011 and 2016. Surgical practices were analyzed for conformity with the current guidelines (www.ovaire-rare.org). Medical records, surgical and pathological reports were systematically analyzed. Total conformity was defined by a conservative (unilateral salpingo-oophorectomy) or radical surgery (hysterectomy and bilateral salpingo-oophorectomy) including surgical staging (omentectomy, peritoneal biopsies and peritoneal cytology) according to the FIGO stage. Partial conformity referred to a conservative or radical surgery without surgical staging and non-conformity was defined as a non-optimal surgery as recommended by the guidelines.Median age at diagnosis was 49 years old (range 10-89). The median size of tumor was 94 mm (range 5-400). Radical surgery was performed in 240 patients (52%); while a fertility-sparing surgery was performed in 98 cases (21%). A surgical staging was performed in 76 cases (16%) and an evaluation of the endometrium in 289 cases (62%). Surgery was fully compliant with the guidelines in 65 patients (14%), partially compliant in 213 patients (46%), non-compliant in 137 patients (30%) and not assessable in 48 cases (10%). A statistically significant difference for compliance was observed in restaging surgery (p 0,001), radical surgery (p = 0,017) and the period (before or after) of the implementation of the network (p 0,001). Survival analyses did not allow us to demonstrate a significant difference in overall survival nor in PFS although there was a trend in favor of optimal surgery compared to incomplete/non optimal surgery.Surgical management's conformity to the guidelines increases over time from 2011 to 2016. According to this study, the implementation of a national network dedicated to rare gynecologic tumors seems to significantly improve the surgical management of the patients with ovarian granulosa cell tumors.

This study aimed to compare the self-reported perceptions of the repercussions of the disease and its treatments and emotional distress in young women with breast cancer and their partners.Cross-sectional study using self-reported questionnaires.491 couples in which women were aged45 years when diagnosed with non-metastatic breast cancer in four different groups of treatment: during chemotherapy with or without Trastuzumab; under Trastuzumab with or without hormone therapy; during hormone therapy; and during the follow-up period.Patients and partners completed a questionnaire assessing their self-reported perceptions of the disease and treatments (Patient YW-BCI and Partner YW-BCI for the partners) and their emotional distress (CESD; STAI).Patients reported more difficulties than partners in the management of child(ren) and everyday life, body image and sexuality, negative affectivity about the disease and apprehension about the future, career management, and finances. While the difficulties were generally more marked in the chemotherapy and Trastuzumab groups than in the hormone therapy and follow-up groups, the negative affectivity about the disease and apprehension about the future was high in all four groups, especially in patients. The partners reported more difficulties in sharing with close relatives, and even more in those groups reflecting the latest treatment phases. No difference appeared between patients and partners in couple cohesion and deterioration of relationships with relatives. Partners were less anxious than patients but as depressed as them.Difficulties of patients and partners seem particularly severe in the early care pathway, maybe reflecting better adjustment in women under surveillance and their partners. A longitudinal study will substantiate this finding and enable a better identification of some explanatory processes of these differences and similarities in the daily self-reported repercussions of the disease throughout the cancer care pathway. Implications for psychosocial oncology: It seems important to support young women with breast cancer and their partners, as our results evidence distress in both and differences according to the type of treatment the woman is currently receiving. Healthcare providers need consistent methods to identify and respond to couples' distress and reduce significant disparities in support.

Real-life analysis of overall survival (OS) trends among metastatic breast cancer (MBC) patients may help define medical needs and evaluate the impact of public health investments. The present study aimed to evaluate the independent impact of the year of MBC diagnosis on OS in the Epidemio-Strategy-Medical-Economical (ESME)-MBC cohort.ESME-MBC (NCT03275311) is a French, national, multicentre, observational cohort including 16,702 consecutive newly diagnosed MBC patients (01 January 2008-31 December 2014). Of 16,680 eligible patients, 15,085 had full immunohistochemistry data, allowing classification as hormone receptor-positive and HER2-negative (HR+/HER2-, N = 9907), HER2-positive (HER2+, N = 2861) or triple-negative (HR-/HER2-, N = 2317) subcohorts. Multivariate analyses of OS were conducted among the full ESME cohort and subcohorts.Median OS of the whole cohort was 37.22 months (95% confidence interval [CI], 36.3-38.04). Year of diagnosis was an independent predictor of OS (hazard ratio 0.98 [95% CI, 0.97-1.00], P = .01) together with age, subtype, disease-free interval, visceral metastases and number of organs involved. Median OS of HR+/HER2-, HER2+ and HR-/HER2- subcohorts was, respectively, 42.12 (95% CI, 40.90-43.10), 44.91 (95% CI, 42.51-47.90) and 14.52 (95% CI, 13.70-15.24) months. Year of diagnosis was a strong independent predictor of OS in HER2+ subcohort (hazard ratio 0.91 [95% CI, 0.88-0.94], P .001), but not in HR+/HER2- nor HR-/HER2- subcohorts (hazard ratio 1.00 [95% CI, 0.98-1.01], P = .80 and 1.00 [95% CI, 0.97-1.02], P = .90, respectively).The OS of MBC patients has slightly improved over the past decade. However, this effect is confined to HER2+ cases, highlighting the need of new strategies in the other subtypes.

Background Rare ovarian tumors represent >20% of all ovarian cancers. Given the rarity of these tumors, natural history, prognostic factors are not clearly identified. The extreme variability of patients (age, histological subtypes, stage) induces multiple and complex therapeutic strategies. Methods Since 2011, a national network with a dedicated system for referral, up to 22 regional and three national reference centers (RC) has been supported by the French National Cancer Institute (INCa). The network aims to prospectively monitor the management of rare ovarian tumors and provide an equal access to medical expertise and innovative treatments to all French patients through a dedicated website, www.ovaire-rare.org . Results Over a 5-year activity, 4612 patients have been included. Patients’ inclusions increased from 553 in 2011 to 1202 in 2015. Expert pathology review and patients’ files discussion in dedicated multidisciplinary tumor boards increased from 166 cases in 2011 (25%) to 538 (45%) in 2015. Pathology review consistently modified the medical strategy in 5–9% every year. The rate of patients’ files discussed in RC similarly increased from 294 (53%) to 789 (66%). An increasing number (357 in 5 years) of gynecologic (non-ovarian) rare tumors were also registered by physicians seeking for pathological or medical advice from expert tumor boards. Conclusion Such a nation-wide organization for rare gynecological tumors has invaluable benefits, not only for patients, but also for epidemiological, clinical and biological research.

Background : The quality of life of couples which one of the members is affected by a cancerous pathology at a relatively young age is important to evaluate in global care. No questionnaire specifically addresses some thematic proper to young women (ex education, desire for a child(s), couple relationship), problems which are yet important for young women suffering from breast cancer. Besides, no questionnaire evaluates the partner's quality of life in this particular context, even if he is frequently the first source of support for the woman (Vanlemmens et al., 2012). Objectives : The main objective was to create a particular and specific tool for measuring the impact of breast cancer on the quality of life of young women (< 45 years of age) with non-metastatic disease and the quality of life of their partners. This work presents the psychometric validation of two questionnaires for patient and partner consisted of items comparable to the semantic level. Methods: We followed the different steps to construct a quality of life tool. After preliminary non-directive interviews and identification of relevant items, we administered the questionnaires on a wide sample of 546 young breast cancer patients and 497 partners. Psychometric testing assessed the hypothesized scale structure based on an examination of item-scale correlation, scale reliability by testing for internal consistency using Cronbach's alpha coefficient, construct validity with inter-scale correlations. Results : Items analyses indicate a good internal consistency of both questionnaires (superior to .75). This questionnaire includes 37 items. The factorial structure highlights 8 factors : 1) management of children and of everyday life, 2) negative affectivity and apprehension about future, 3) feeling of couple cohesion, 4) financial difficulties, 5) body image and sexual life, 6) deterioration with close relations, 7) sharing and support of close relations, and 8) management of the professional life..This structure explains respectively 56% for the patients and 58% for the partners of the total variance. As expected, convergent validity showed strong correlations with Kalicou scales and quality of life measures (QLQC-30 and QLQBR-23). Conclusions: Overall psychometric results for the 2 Kalicou questionnaires confirmed them as valid questionnaires for breast cancer patients and partners. This study will allow the clinicians to have a measurement tool for subjective real-life experience of young breast cancer women and their partner. These questionnaires will also allow comparisons according to the stage and study the interactions of couple. This tool should help to identify modifications of the subjective quality of life. The objective is to improve the medical, psychological and social care for patients and their partner, with a systemic, dynamic approach.

Background: Cognitive impairment has been considered to be a possible adverse effect of aromatase inhibitors (AI). The aim of the study was to compare the impact of tamoxifen or AI on verbal memory (Rey auditory-verbal learning test) and other cognitive functions (memory, executive and attentional functions) after 6 months of treatment. Methods: In this randomized, open-label phase III study, menopausal patients treated with adjuvant hormonotherapy for early breast cancer were enrolled at the end of the radiotherapy. Patients over 70 years, with a history of cognitive disorder or with prior chemotherapy were excluded. Detailed neuropsychological assessments and quality of life evaluations were performed before the 1st administration of hormonotherapy and then 6 months later. Considering the usual norms of the auditivo-verbal Rey test, an alpha risk of 5% and a 95% power, 27 patients per arm had to be included. Statistical analyses included Chi2 test and Student tests when appropriate. Results: 62 consecutive evaluable patients were randomized in 2 arms between March 2009 and April 2011. Patients received tamoxifen in arm A (n = 31) and AI in arm B (letrozole n=17; anastrozole n=12; exemestane n= 2). Median age at inclusion was 61.4 years. The median time since menopause was 10 years. Characteristics of the breast tumor and initial neuropsychological evaluations did not differ significantly between the 2 arms. After 6 months, we observed a significant decline of the performance at the episodic memory test (immediate recall of the Rey auditory verbal learning test) (p = 0.0015) in arm A only and a significant improvement on executive measures (Trail Making Test and Stroop test) (respectively p = 0.03/p = 0.002) in arm B. Quality of life didn't differ after 6 months of treatment. Conclusions: These preliminary results do not support that AI have a worse adverse effect on cognitive functions than tamoxifen after 6 months of treatment. A confirmation is planned after one year of treatment. Citation Information: Cancer Res 2012;72(24 Suppl):Abstract nr P2-13-10.

Resume Introduction Les soins palliatifs visent a assurer une prise en charge globale des personnes en fin de vie; ils impliquent de nombreux intervenants, parmi lesquels les medecins, generalistes ou specialistes, qui jouent un role essentiel. Les professionnels des unites de soins palliatifs (USP) doivent avoir a l’admission un courrier detaille, ceci afin de pouvoir apporter au patient des soins et un soutien appropries. Objectifs de l’etude Analyser le contenu des courriers d’admission des patients dans les unites de soins palliatifs. Proposer une « lettre type » d’admission. Patients, materiel et methode Nous avons etudie les courriers d’admission de 45 patients admis dans deux unites de soins palliatifs bretonnes et decedes pendant l’annee 2002. Resultats Il apparait que ces courriers sont insuffisamment detailles, tant pour les donnees evolutives de la maladie, que pour ce que connait le patient de sa maladie et son evolution, et ce quel que soit le statut du medecin qui adresse. Apres avoir discute les raisons de cette carence, nous proposons en annexe un modele de lettre type, qui pourrait etre utilisee par tout medecin proposant un patient dans les unites de soins palliatifs et qui permettrait de ne pas oublier des items primordiaux.

TPS10126 Background: Fatigue is a frequent side effect with oral targeted therapies (OTT). Physical activity has been reported to improve fatigue and quality of life (QoL). However, few studies focused on metastatic cancer patients and mainly among patients treated with chemotherapy. Furthermore, recent guidelines recommend evaluation and optimization of standardized exercise programs. The aim of our study is to evaluate home-based standard physical exercise program (SPEP) for metastatic cancer patients treated with OTT. Methods: This phase II-III study will randomize (2:1) patients starting first-line OTT for metastatic cancer between an individualized SPEP supervised by a personal coach, and recommended physical exercises via a booklet. Eligible patients will have received ≤2 lines of metastatic chemotherapy, ECOG PS ≤2, controlled pain (VAS < 3/10), and life expectancy ≥3 months. The phase II part (120 patients) will evaluate the feasibility of a 3-month SPEP using the rate of patients performing ≥50% of SPEP (2-stage Fleming: one-sided α = 5%; β = 85%). An interim analysis is planned after the phase II. The phase III will compare the efficacy of an SPEP as opposed to recommendations to reduce fatigue and/or improve physical well-being (PWB) dimensions of QoL (evaluated with FACT-G and FACT-F questionnaires). To show a difference of ≥5 points in PWB and 2.5 for fatigue (α = 2.5%; β = 80%), 312 patients are required in the phase III trial. . Secondary objectives include: PFS, OS, other dimensions of QoL, tolerability and observance of OTT, change in body composition, physical benefits, and a medico-economic study. The SPEP was developed by specialized coaches involved in physical activity and cancer. The study has Ethic committee approval and accrual is planned in 18 French centers in April 2017, for 30 months. This is the first randomized trial dedicated to patients with metastatic cancer treated with OTT evaluating the feasibility and the efficacy of a well design home based SPEP on fatigue and physical well-being.

Background Mutations of BRAF, NRAS and c-KIT oncogenes are preferentially described in certain histological subtypes of melanoma and linked to specific histopathological features. BRAF-, MEK- and KIT-inhibitors led to improvement in overall survival of patients harbouring mutated metastatic melanoma. Objectives To assess the prevalence and types of BRAF, NRAS, c-KIT and MITF mutations in cutaneous and mucous melanoma and to correlate mutation status with clinicopathological features and outcome. Methods Clinicopathological features and mutation status of 108 samples and of 98 consecutive patients were, respectively, assessed in one retrospective and one prospective study. Clinicopathological features were correlated with mutation status and the predictive value of these mutations was studied. Results This work identified significant correlations between BRAF mutations and melanoma occurring on non-chronic sun-damaged skin and superficial spreading melanoma (P < 0.05) on one hand, and between NRAS mutations and nodular melanoma (P < 0.05) on the other hand. Younger age (P < 0.05), microscopic (P < 0.05) and macroscopic (P < 0.05) lymphatic involvement at diagnosis of primary melanoma were significantly linked to BRAF mutations. A mutated status was a positive predictive factor of a response to BRAF inhibitors (OR = 3.44). Mutated melanoma showed a significantly (P = 0.038) higher objective response rate to cytotoxic chemotherapy (26.3%) than wild-type tumours (6.7%). Conclusion Clinical and pathological characteristics of the primary melanoma differed between wild-type and BRAFor NRAS-mutated tumours. Patients with BRAF-mutated tumours were younger at diagnosis of primary melanoma. Patients carrying mutations showed better responses better to specific kinase inhibitors and interestingly also to systemic cytotoxic chemotherapy.

In a randomized phase III study, trametinib prolonged progression-free survival and improved overall survival versus chemotherapy in patients with BRAF V600 mutation-positive melanoma.Patients' quality of life (QOL) was assessed at baseline and follow-up visits using the European Organisation for Research and Treatment of Cancer Core QOL questionnaire.In the primary efficacy population (BRAF V600E+, no brain metastases) from baseline to weeks 6 and 12, patients' global health status scores worsened by 4-5 points with chemotherapy but improved by 2-3 points with trametinib. Rapid and substantive reductions in QOL functionality (e.g. role functioning, 8-11 points at weeks 6 and 12) and symptom exacerbation (e.g. fatigue, 4-8 points; nausea and vomiting, 5 points, both at weeks 6 and 12) were observed in chemotherapy-treated patients. In contrast, trametinib-treated patients reported small improvements or slight worsening from baseline at week 12, depending on the functional dimension and symptom. The mean symptom-scale scores for chemotherapy-treated patients increased from baseline (symptoms worsened) for seven of eight symptoms at week 6 (except insomnia) and six of eight symptoms at week 12 (except dyspnea and insomnia). In contrast, at weeks 6 and 12, the mean symptom-scale scores for trametinib decreased from baseline (symptoms improved) for pain (11-12 points), insomnia (10-12 points), and appetite loss (1-5 points), whereas those for diarrhea worsened (15-16 points). Mixed-model repeated-measures analyses showed significant (P0.05) and/or clinically meaningful improvements (small to moderate) from baseline in favor of trametinib for global health; physical, role, and social functioning; fatigue; pain; insomnia; nausea and vomiting; constipation; dyspnea; and appetite at weeks 6 and/or 12. QOL results for the intent-to-treat population were consistent.This first QOL assessment for a MEK inhibitor in metastatic melanoma demonstrated that trametinib was associated with less functional impairment, smaller declines in health status, and less exacerbation of symptoms versus chemotherapy.

Metastatic melanoma is one of the most aggressive tumours, with a median survival that does not exceed 12 months. None of the cytotoxic first-line therapies have shown survival benefit in randomised clinical trials.To describe clinical benefit of second-line cytotoxic chemotherapy in the second line of treatment for metastatic melanoma.In a retrospective study, we analyse the outcome of patients with metastatic melanoma who had received two lines or more of cytotoxic treatments in four French dermato-oncology departments between 1999 and 2009.We describe the outcomes for 109 patients. Most of these patients received dacarbazine for the first line of chemotherapy and fotemustine for the second line of chemotherapy (67.0 and 64.2%, respectively). A clinical benefit was observed in 24.1% of the patients and overall survival was 4.1 months after the second-line treatment. At least 23.8% of patients suffered from grade 3 or 4 toxicities. The presence of more than two sites of metastasis and an M1c staging according to the AJCC classification represented negative predictive factors of clinical benefit.This study shows the modest benefit of a second line of cytotoxic chemotherapy in a nonselected population. If eligible, these patients should be proposed for ongoing clinical trials or for targeted therapies.

Several lines of chemotherapy can be proposed for patients with metastatic breast cancer, but beyond the second line, agreement is lacking concerning the most appropriate therapeutic strategy. We conducted a retrospective analysis of the files of 162 patients, who had received at least 3 lines of chemotherapy (CT3) for metastatic breast cancer during a 5-year period (2000–2004), in order to analyze management practices and search for factors affecting survival from CT3 and predictive factors of non-progressive disease (NPD) after CT3. Multivariate analysis identified seven factors which had a positive influence on survival from CT3 (SBR grade I, absence of adjuvant hormone therapy, free interval ≥2 years, absence of cerebromeningeal metastasis before CT, unique focus at initiation of CT3, use of polychemotherapy for CT2, and complete response to CT1 or CT2) and two predictive factors of NPD (histology and drug group used for CT3). These factors should help determine the appropriate strategy for proposing a third line of chemotherapy.
