Investigating the prognostic impact of NY-ESO-1 expression and HLA subtypes in metastatic synovial sarcoma.

BACKGROUND: To better understand the importance of New York esophageal squamous cell carcinoma 1 (NY-ESO-1) and human leukocyte antigen (HLA) subtype in treatment decision making, further investigation of their prevalence and prognostic impact among patients with metastatic synovial sarcoma (mSS) is needed. PATIENTS AND METHODS: This was a retrospective clinico-biological cohort study of adults with mSS. Patient data were collected from the French Sarcoma Group NetSARC database and supplemented by electronic medical records. Primary tumor samples were collected and analyzed for NY-ESO-1 expression by immunohistochemistry (IHC) and HLA-A∗02 status by RNA sequencing (RNA-seq). The primary cohort included patients with available primary tumor samples; the impact of a larger sample size was explored by including patients who had either a primary or metastatic sample (termed the exploratory cohort). P values are provided for descriptive purposes. RESULTS: In 92 patients with primary tumor samples, ∼25% (n = 23) were positive for NY-ESO-1 and HLA-A∗02 expression (dual positive). Among 106 patients with IHC data, 61% (n = 65) were NY-ESO-1 positive, and among 94 patients with RNA-seq data, 45% (n = 42) were HLA-A∗02 positive. The median overall survival (OS) for positive versus negative NY-ESO-1 status was 35.3 and 21.7 months, respectively (unadjusted P = 0.0428). We observed no difference in median OS for HLA-A∗02-positive versus -negative and dual-positive patients versus others (both unadjusted P > 0.05). Multivariate analyses of OS showed no prognostic impact for NY-ESO-1 among primary tumor samples and in the exploratory cohort. However, in the latter, we observed an association between NY-ESO-1 expression and OS in the first-line (P = 0.0041) but not in the second-line setting. CONCLUSIONS: The primary tumor cohort showed no association between NY-ESO-1 expression and OS (including stratification by HLA-A∗02 subtype and treatment line), when adjusting for important prognostic factors, possibly due to small sample sizes.

Prognostic value of EndoPredict test in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative primary breast cancer screened for the randomized, double-blind, phase III UNIRAD trial.

BACKGROUND: The purpose of this study was to evaluate the prognostic value of the multigene EndoPredict test in prospectively collected data of patients screened for the randomized, double-blind, phase III UNIRAD trial, which evaluated the addition of everolimus to adjuvant endocrine therapy in high-risk, hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer. PATIENTS AND METHODS: Patients were classified into low or high risk according to the EPclin score, consisting of a 12-gene molecular score combined with tumor size and nodal status. Association of the EPclin score with disease-free survival (DFS) and distant metastasis-free survival (DMFS) was evaluated using Kaplan-Meier estimates. The independent prognostic added value of EPclin score was tested in a multivariate Cox model after adjusting on tumor characteristics. RESULTS: EndoPredict test results were available for 768 patients: 663 patients classified as EPclin high risk (EPCH) and 105 patients as EPclin low risk (EPCL). Median follow-up was 70 months (range 1-172 months). For the 429 EPCH randomized patients, there was no significant difference in DFS between treatment arms. The 60-month relapse rate for patients in the EPCL and EPCH groups was 0% and 7%, respectively. Hazard ratio (HR) supposing continuous EPclin score was 1.87 [95% confidence interval (CI) 1.4-2.5, P < 0.0001]. This prognostic effect remained significant when assessed in a Cox model adjusting on tumor size, number of positive nodes and tumor grade (HR 1.52, 95% CI 1.09-2.13, P = 0.0141). The 60-month DMFS for patients in the EPCL and EPCH groups was 100% and 94%, respectively (adjusted HR 8.10, 95% CI 1.1-59.1, P < 0.0001). CONCLUSIONS: The results confirm the value of EPclin score as an independent prognostic parameter in node-positive, hormone receptor-positive, HER2-negative early breast cancer patients receiving standard adjuvant treatment. EPclin score can be used to identify patients at higher risk of recurrence who may warrant additional systemic treatments.

Regorafenib in patients with relapsed advanced or metastatic chordoma: results of a non-comparative, randomised, double-blind, placebo-controlled, multicentre phase II study.

BACKGROUND: REGOBONE multicohort study explored the efficacy and safety of regorafenib for patients with advanced bone sarcomas; this report details the cohort of patients with relapsed advanced or metastatic chordoma. METHODS: Patients with relapsed chordoma progressing despite 0-2 prior lines of systemic therapy, were randomised (2 : 1) to receive regorafenib (160 mg/day, 21/28 days) or placebo. Patients on placebo could cross over to receive regorafenib after centrally-confirmed progression. The primary endpoint was the progression-free rate at 6 months (PFR-6) (by RECIST 1.1). With one-sided α of 0.05, and 80% power, at least 10/24 progression-free patients at 6 months (PFR-6) were needed for success. RESULTS: From March 2016 to February 2020, 27 patients were enrolled. A total of 23 patients were assessable for efficacy: 7 on placebo, 16 on regorafenib, 16 were men, median age was 66 (32-85) years. At 6 months, in the regorafenib arm, 1 patient was not assessable, 6/14 were non-progressive (PFR-6: 42.9%; one-sided 95% CI = 20.6) 3/14 discontinued regorafenib due to toxicity; and in the placebo arm, 2/5 patients were non-progressive (PFR-6: 40.0%; one-sided 95% CI = 7.6), 2 were non-assessable. Median progression-free survival was 8.2 months (95% CI 4.5-12.9 months) on regorafenib and 10.1 months (95% CI 0.8 months-non evaluable [NE]) on placebo. Median overall survival rates were 28.3 months (95% CI 14.8 months-NE) on regorafenib but not reached in placebo arm. Four placebo patients crossed over to receive regorafenib after centrally-confirmed progression. The most common grade ≥3 regorafenib-related adverse events were hand-foot skin reaction (22%), hypertension (22%), pain (22%), and diarrhoea (17%), with no toxic death. CONCLUSION: This study failed to show any signal of benefit for regorafenib in patients with advanced/metastatic recurrent chordoma.

Reduced risk of secondary primary extra pulmonary cancer in advanced/metastatic lung cancer patients treated with immune checkpoint inhibitors.

BACKGROUND: Lung cancer survivors are at high risk of developing a second primary cancer (SPC). We explored the Unicancer Epidemiology Strategy Medical-Economics for advanced or metastatic lung cancer (AMLC) database to assess the impact of immune checkpoint inhibitors (ICI) on the risk of SPC in patients with advanced/metastatic lung cancer. PATIENTS AND METHODS: This retrospective study used data from patients with AMLC, with treatment initiated between January 1st 2015 and December 31st 2018. Patients with lung cancer as the second primary cancer were excluded and a 6-months landmark threshold was applied to exclude patients with synchronous SPC, patients dead without SPC or with a follow-up inferior to 6 months. A propensity score (PS) was calculated on the following baseline covariates: Age at locally advanced or metastatic diagnosis, sex, smoking status, metastatic status, performance status and histological type. The inverse probability of treatment weighting approach was used on the analyses aiming to assess the impact of ICI administered for AMLC, on the risk of occurrence of SPC. RESULTS: Among the 10 796 patients, 148 (1.4%) patients had a diagnosis of SPC in a median interval of 22 (min-max: 7-173) months. All the patients (100%) with locally advanced or metastatic LC received at least one systemic treatment including (chemotherapy regimen (n = 9 851, 91.2%); ICI (n = 4 648, 43.0%); targeted treatment (n = 3 500; 32.4%). 40 (0.9%) SPC were reported in the 4 648 patients with metastatic LC treated with ICI vs 108 (1.7%) out of the 6 148 who did not receive immunotherapy (p < 0.0001). The multivariate analysis identified that treatment with ICI in patients with AMLC is associated with a reduced risk of SPC (HR = 0.40, 95% CI 0.27-0.58). CONCLUSION: Treatment with ICI in AMLC patients was associated with a significantly reduced risk of SPC. Prospective studies are required to confirm these results.

Metastatic inflammatory breast cancer: survival outcomes and prognostic factors in the national, multicentric, and real-life French cohort (ESME).

BACKGROUND: Primary inflammatory breast cancer (IBC) is a rare and aggressive entity whose prognosis has been improved by multimodal therapy. However, 5-year overall survival (OS) remains poor. Given its low incidence, the prognosis of IBC at metastatic stage is poorly described. MATERIALS AND METHODS: This study aimed to compare OS calculated from the diagnosis of metastatic disease between IBC patients and non-IBC patients in the Epidemiological Strategy and Medical Economics database (N = 16 702 patients). Secondary objectives included progression-free survival (PFS) after first-line metastatic treatment, identification of prognostic factors for OS and PFS, and evolution of survival during the study period. RESULTS: From 2008 to 2014, 7465 patients with metastatic breast cancer and known clinical status of their primary tumor (T) were identified (582 IBC and 6883 non-IBC). Compared with metastatic non-IBC, metastatic IBC was associated with less hormone receptor-positive (44% versus 65.6%), more human epidermal growth factor receptor 2-positive (30% versus 18.6%), and more triple-negative (25.9% versus 15.8%) cases, more frequent de novo M1 stage (53.3% versus 27.7%; P < 0.001), and shorter median disease-free interval (2.02 years versus 4.9 years; P < 0.001). With a median follow-up of 50.2 months, median OS was 28.4 months [95% confidence interval (CI) 24.1-33.8 months] versus 37.2 months (95% CI 36.1-38.5 months) in metastatic IBC and non-IBC cases, respectively (P < 0.0001, log-rank test). By multivariate analysis, OS was significantly shorter in the metastatic IBC group compared with the metastatic non-IBC group [hazard ratio = 1.27 (95% CI 1.1-1.4); P = 0.0001]. Survival of metastatic IBC patients improved over the study period: median OS was 24 months (95% CI 20-31.9 months), 29 months (95% CI 21.7-39.9 months), and 36 months (95% CI 27.9-not estimable months) if diagnosis of metastatic disease was carried out until 2010, between 2011 and 2012, and from 2013, respectively (P = 0.003). CONCLUSION: IBC is independently associated with adverse outcome when compared with non-IBC in the metastatic setting.

Delayed care for patients with newly diagnosed cancer due to COVID-19 and estimated impact on cancer mortality in France.

BACKGROUND: The impact of the first coronavirus disease 2019 (COVID-19) wave on cancer patient management was measured within the nationwide network of the Unicancer comprehensive cancer centers in France. PATIENTS AND METHODS: The number of patients diagnosed and treated within 17 of the 18 Unicancer centers was collected in 2020 and compared with that during the same periods between 2016 and 2019. Unicancer centers treat close to 20% of cancer patients in France yearly. The reduction in the number of patients attending the Unicancer centers was analyzed per regions and cancer types. The impact of delayed care on cancer-related deaths was calculated based on different hypotheses. RESULTS: A 6.8% decrease in patients managed within Unicancer in the first 7 months of 2020 versus 2019 was observed. This reduction reached 21% during April and May, and was not compensated in June and July, nor later until November 2020. This reduction was observed only for newly diagnosed patients, while the clinical activity for previously diagnosed patients increased by 4% similar to previous years. The reduction was more pronounced in women, in breast and prostate cancers, and for patients without metastasis. Using an estimated hazard ratio of 1.06 per month of delay in diagnosis and treatment of new patients, we calculated that the delays observed in the 5-month period from March to July 2020 may result in an excess mortality due to cancer of 1000-6000 patients in coming years. CONCLUSIONS: In this study, the delays in cancer patient management were observed only for newly diagnosed patients, more frequently in women, for breast cancer, prostate cancer, and nonmetastatic cancers. These delays may result is an excess risk of cancer-related deaths in the coming years.

Immune checkpoint inhibitor treatment of a first cancer is associated with a decreased incidence of second primary cancer.

BACKGROUND: Second primary cancers (SPCs) are diagnosed in over 5% of patients after a first primary cancer (FPC). We explore here the impact of immune checkpoint inhibitors (ICIs) given for an FPC on the risk of SPC in different age groups, cancer types and treatments. PATIENTS AND METHODS: The files of the 46 829 patients diagnosed with an FPC in the Centre Léon Bérard from 2013 to 2018 were analyzed. Structured data were extracted and electronic patient records were screened using a natural language processing tool, with validation using manual screening of 2818 files of patients. Univariate and multivariate analyses of the incidence of SPC according to patient characteristics and treatment were conducted. RESULTS: Among the 46 829 patients, 1830 (3.9%) had a diagnosis of SPC with a median interval of 11.1 months (range 0-78 months); 18 128 (38.7%) received cytotoxic chemotherapy (CC) and 1163 (2.5%) received ICIs for the treatment of the FPC in this period. SPCs were observed in 7/1163 (0.6%) patients who had received ICIs for their FPC versus 437/16 997 (2.6%) patients receiving CC and no ICIs for the FPC versus 1386/28 669 (4.8%) for patients receiving neither CC nor ICIs for the FPC. This reduction was observed at all ages and for all histotypes analyzed. Treatment with ICIs and/or CC for the FPC are associated with a reduced risk of SPC in multivariate analysis. CONCLUSION: Immunotherapy with ICIs alone and in combination with CC was found to be associated with a reduced incidence of SPC for all ages and cancer types.

Molecular screening program to select molecular-based recommended therapies for metastatic cancer patients: analysis from the ProfiLER trial.

BACKGROUND: Antitumor activity of molecular-targeted agents is guided by the presence of documented genomic alteration in specific histological subtypes. We aim to explore the feasibility, efficacy and therapeutic impact of molecular profiling in routine setting. PATIENTS AND METHODS: This multicentric prospective study enrolled adult or pediatric patients with solid or hematological advanced cancer previously treated in advanced/metastatic setting and noneligible to curative treatment. Each molecular profile was established on tumor, relapse or biopsies, and reviewed by a molecular tumor board (MTB) to identify molecular-based recommended therapies (MBRT). The main outcome was to assess the incidence rate of genomic mutations in routine setting, across specific histological types. Secondary objectives included a description of patients with actionable alterations and for whom MBRT was initiated, and overall response rate. RESULTS: Four centers included 2579 patients from February 2013 to February 2017, and the MTB reviewed the molecular profiles achieved for 1980 (76.8%) patients. The most frequently altered genes were CDKN2A (N = 181, 7%), KRAS (N = 177, 7%), PIK3CA (N = 185, 7%), and CCND1 (N = 104, 4%). An MBRT was recommended for 699/2579 patients (27%), and only 163/2579 patients (6%) received at least one MBRT. Out of the 182 lines of MBRT initiated, 23 (13%) partial responses were observed. However, only 0.9% of the whole cohort experienced an objective response. CONCLUSION: An MBRT was provided for 27% of patients in our study, but only 6% of patients actually received matched therapy with an overall response rate of 0.9%. Molecular screening should not be used at present to guide decision-making in routine clinical practice outside of clinical trials.This trial is registered with ClinicalTrials.gov, number NCT01774409.

Endocrine therapy or chemotherapy as first-line therapy in hormone receptor-positive HER2-negative metastatic breast cancer patients.

BACKGROUND: For hormone receptor-positive (HR+) human epidermal growth factor receptor 2 (HER2-) negative metastatic breast cancer (MBC), international guidelines recommend endocrine therapy as first-line treatment, except in case of 'visceral crisis'. In the latter case, chemotherapy is preferred. Few studies have compared these two strategies. We used the Epidemiological Strategy and Medical Economics (ESME) programme, UNICANCER, a large national observational database (NCT03275311), to address this question. METHODS: All patients who initiated treatment for a newly diagnosed HR+ HER2-negative MBC between January 2008 and December 2014 in any of the 18 French Comprehensive Cancer Centers participating to ESME were selected. Patients should be aromatase inhibitor (AI)-sensitive (no previous AI or relapse occurring more than 1 year after last adjuvant AI). Objectives of the study were evaluation of progression-free and overall survival (OS) according to the type of first-line treatment adjusted on main prognostic factors using a propensity score. RESULTS: Six thousand two hundred sixty-five patients were selected: 2733 (43.6%) received endocrine therapy alone, while 3532 (56.4%) received chemotherapy as first-line therapy. Among the latter, 2073 (58.7%) received maintenance endocrine therapy. Median OS was 60.78 months (95% confidence interval [CI], 57.16-64.09) and 49.64 months (95% CI, 47.31-51.64; p < 0.0001) for patients receiving endocrine therapy alone and chemotherapy ± maintenance endocrine therapy, respectively. However, this difference was not significant after adjusting on the propensity score (hazard ratio: 0.943, 95% CI 0.863-1.030, p = 0.19). CONCLUSION: In this large retrospective cohort of patients with AI-sensitive metastatic luminal BC, OS was similar, whether first-line treatment was chemotherapy or endocrine therapy. In agreement with international guidelines, endocrine therapy should be the first choice for first-line systemic treatment for MBC in the absence of visceral crisis.

Mathematical model of T-cell lymphoblastic lymphoma: disease, treatment, cure or relapse of a virtual cohort of patients.

T lymphoblastic lymphoma (T-LBL) is a rare type of lymphoma with a good prognosis with a remission rate of 85%. Patients can be completely cured or can relapse during or after a 2-year treatment. Relapses usually occur early after the remission of the acute phase. The median time of relapse is equal to 1 year, after the occurrence of complete remission (range 0.2-5.9 years) (Uyttebroeck et al., 2008). It can be assumed that patients may be treated longer than necessary with undue toxicity.The aim of our model was to investigate whether the duration of the maintenance therapy could be reduced without increasing the risk of relapses and to determine the minimum treatment duration that could be tested in a future clinical trial.We developed a mathematical model of virtual patients with T-LBL in order to obtain a proportion of virtual relapses close to the one observed in the real population of patients from the EuroLB database. Our simulations reproduced a 2-year follow-up required to study the onset of the disease, the treatment of the acute phase and the maintenance treatment phase.

Pre-radiation chemotherapy improves survival in pediatric diffuse intrinsic pontine gliomas.

BACKGROUND: The median survival of patients with diffuse intrinsic pontine glioma (DIPG) remains less than 1 year. The BSG 98 pre-irradiation chemotherapy protocol showed a significant increase in overall survival. In contrast to current treatment strategies, patients did not have to undergo surgical stereotactic biopsy, which can sometimes lead to complications, to be included in this protocol. MATERIALS AND METHODS: We retrospectively reviewed all the cases of DIPG that were treated in our department from September 15, 2004 to September 15, 2014. We compared the group of patients who followed our BSG 98 protocol to those who were treated with new targeted therapy protocols where systematic biopsy was required. RESULTS: Patients in the BSG 98 protocol were treated with BCNU, cisplatin, and methotrexate, followed by radiation at disease progression. Targeted therapy protocols included radiation therapy along with treatment by erlotinib, cilengitide, or an association of nimotuzumab and vinblastine. Sixteen patients were treated with the BSG 98 protocol, and 9 patients were treated with new targeted therapy protocols. Median overall survival was significantly higher in the BSG 98 group compared to the targeted therapy group (16.1 months (95 % CI, 10.4-19.0) vs 8.8 months (95 % CI 1.4-12.3); p = 0.0003). An increase in the median progression-free survival was observed (respectively, 8.6 vs 3.0 months; p = 0.113). CONCLUSION: The present study confirms that the BSG 98 protocol is one of the most effective current treatment strategies for DIPG. It may be used as the control arm in randomized trials investigating the use of innovative treatments and may be proposed to families who are averse to biopsy.

Organ-specific matrix self-assembled by mesenchymal cells improves the normal urothelial differentiation in vitro.

PURPOSE: Enterocystoplasty is the gold standard to perform bladder reconstruction. Since this technique has a high morbidity rate, several matrix scaffolds have been proposed to support the urothelial maturation. Unfortunately, epithelial cells failed to fully integrate the cell-matrix interactions and therefore appropriate signalling pathways of normal differentiation. Based on these observations, we proposed to culture bladder urothelial cells (BUC) onto a matrix self-assembled by bladder mesenchymal cells (BMC), to form a vesical model (VM). METHODS: Different serum proportions were assessed to obtain a manipulable matrix deposited by BMC. The BUC were then seeded onto the BMC's matrix to evolve in a three-dimensional culture. Haematoxylin-eosin staining, immunolabeling, scanning electron microscopy, western blot and matrix metalloproteinases analysis were performed for the VM characterization. RESULTS: We were able to obtain an original matrix made of collagen-I and presenting specific organization. Matrix remodelling was observed and led to a cellular compartmentalization. The reconstructed urothelium developed in a pseudostratified arrangement, displaying an adequate cellular polarity and apical membrane remodelling of superficial cells. Like native bladder, cytokeratin 14 immunolabeling was not observed in our VM, which indicate the conformity of the development sequence taken by BUC under the influence of the BMC's matrix. CONCLUSION: Thus, it was possible to elaborate a VM without the use of exogenous matrices. The particular characteristics of the BMC's matrix permitted the development of an urothelium that shared the phenotype of native tissue. The autologous character of our VM, and its appropriate urothelial maturation, could potentially promote a better integration after grafting.

Retroperitoneal nodal metastases from colorectal cancer: Curable metastases with radical retroperitoneal lymphadenectomy in selected patients.

BACKGROUND: Retroperitoneal nodal metastases (RNM) represent 1-2% of metastases from colorectal cancer (CRC). Non-surgical treatments achieve 5-year overall survival (OS) of 0-12%. Radical retroperitoneal lymphadenectomy (RRL) in this setting remains controversial, but most published series do not distinguish local retroperitoneal recurrences from RNM. We specifically report outcomes after RRL for RNM from CRC. METHODS: We analyzed prospectively recorded data from patients who underwent standardized RRL for RNM from CRC between January 1997 and August 2012 in our institution. Local retroperitoneal recurrences were excluded. RESULTS: Twenty-five patients underwent RRL for synchronous (n = 19) or metachronous (n = 6) RNM from CRC. Fifteen patients had extra-retroperitoneal metastases. Median hospital stay was 16 [7-23] days. Grade ≥ III morbidity was 8% with no perioperative deaths. Median follow-up was 85 [4-142] months. Median OS and progression free survival (PFS) were 60 [4-142] and 14 [1-116] months. One, three- and 5-year OS were 92%, 64% and 47%. One, three- and 5-year PFS were 51%, 26% and 26%. Retroperitoneal nodal metastases from stage III CRC were associated with better median OS compared to those from stage IV CRC (p = 0.02). This variable did not impact on PFS. Subject to substantial risk of type II error on small samples data statistical analysis, survivals were not affected by timing and location of RNM, extra-retroperitoneal metastasis, nodal disruption, neoadjuvant nor adjuvant chemotherapy. CONCLUSIONS: To our knowledge, this is the largest series yet reported which specifically studied outcomes of RRL for RNM from CRC. RRL allows favorable outcomes in selected patients with acceptable morbidity.

ELYPSE-7: a randomized placebo-controlled phase IIa trial with CYT107 exploring the restoration of CD4+ lymphocyte count in lymphopenic metastatic breast cancer patients.

BACKGROUND: Lymphopenia is a predictive factor for hematological toxicity, progression and early death in advanced cancers including metastatic breast cancer (MBC). CYT107 is a recombinant interleukin 7 (IL-7) (Cytheris, now Revimmune), well tolerated and able to expand lymphocyte pool in humans. The aims of this study were to determine the optimal schedule to deliver CYT107 and to assess its effect on clinical end points. PATIENT AND METHODS: This placebo-controlled, double blind, phase IIa was conducted in MBC patients with <1500/µl lymphocytes treated with capecitabine. Using a 2-by-2 factorial design, 20 patients were randomly allocated to four arms to receive (i) before chemotherapy: CYT107 or placebo; then (ii) during chemotherapy: CYT107 or placebo. The primary end point was CD4+ count changes before and during chemotherapy. Secondary end points were hematological toxicity, safety, overall response, progression-free survival (PFS) and overall survival (OS). Quantification and functional competence of circulating immune cells were also assessed. RESULTS: When administered before chemotherapy, CYT107 induced a significant increase of CD4+ [+148.1% in CYT107 versus +9.9% in placebo groups, (Wilcoxon, P = 0.002)] and CD8+ T-cell counts, including both naïve and memory subsets. When CYT107 was administered during chemotherapy, the magnitude of CD4+ and CD8+ increase was less important. No modulation of immune cell functional competence was observed. CYT107 was well tolerated with no related ≥grade 3 adverse events except 1 fatal suspected unexpected serious adverse reaction (SUSAR) of uncertain relationship. Of the 12 cases evaluable for response, 6 of 7 patients (86%) receiving CYT107 before chemotherapy achieved a response or stabilization, whereas two of five patients (40%) receiving placebo achieved the same result. No significant difference was observed for PFS or OS. CONCLUSION: In lymphopenic MBC, CYT107 increases CD4+ and other T-cell subset counts without altering their function. A larger clinical trial to demonstrate its impact on clinical outcome is warranted. CLINICALTRIALSGOV IDENTIFIER: NCT01362107.

Design of a randomised controlled trial of adapted physical activity during adjuvant treatment for localised breast cancer: the PASAPAS feasibility study.

INTRODUCTION: After a diagnosis of localised breast cancer, overweight, obesity and weight gain are negatively associated with prognosis. In contrast, maintaining an optimal weight through a balanced diet combined with regular physical activity appears to be effective protective behaviour against comorbidity or mortality after a breast cancer diagnosis. The primary aim of the Programme pour une Alimentation Saine et une Activité Physique Adaptée pour les patientes atteintes d'un cancer du Sein (PASAPAS) randomised controlled trial is to evaluate the feasibility of implementing an intervention of adapted physical activity (APA) for 6 months concomitant with the prescription of a first line of adjuvant chemotherapy. Secondary aims include assessing the acceptability of the intervention, compliance to the programme, process implementation, patients' satisfaction, evolution of biological parameters and the medicoeconomic impact of the intervention. METHODS AND ANALYSIS: The study population consists of 60 women eligible for adjuvant chemotherapy after a diagnosis of localised invasive breast cancer. They will be recruited during a 2-year inclusion period and randomly allocated between an APA intervention arm and a control arm following a 2:1 ratio. All participants should benefit from personalised dietetic counselling and patients allocated to the intervention arm will be offered an APA programme of two to three weekly sessions of Nordic walking and aerobic fitness. During the 6-month intervention and 6-month follow-up, four assessments will be performed including blood draw, anthropometrics and body composition measurements, and questionnaires about physical activity level, diet, lifestyle factors, psychological criteria, satisfaction with the intervention and medical data. ETHICS AND DISSEMINATION: The study was approved by the French Ethics Committee (Comité de Protection des Personnes Sud-Est IV) and the national agencies for biomedical studies and for privacy. All participants will give written informed consent. The study findings will be disseminated through the scientific public and serve as a foundation for future randomised controlled trials of efficacy.

A phase II trial of panobinostat in patients with advanced pretreated soft tissue sarcoma. A study from the French Sarcoma Group.

BACKGROUND: Soft tissue sarcomas (STS) are rare tumours for which treatment options are limited in the advanced setting. Histone deacetylase inhibitors have shown activity in preclinical models of STS. METHODS: We conducted a single-arm, open-label, multicentre phase II study to assess the efficacy and tolerability of panobinostat given orally, 40 mg thrice weekly in patients with advanced pretreated STS. The primary endpoint was the 3-month progression-free rate. RESULTS: Forty-seven STS patients were enrolled between January 2010 and December 2010. Median age was 59 (range 21-79) years, 22 (47%) patients were males. Panobinostat dose was lowered to 20 mg thrice weekly after nine patients were enrolled, based on the recommendation of an independent safety committee. The most common grade 3/4 adverse events were thrombocytopenia, fatigue, lymphopenia and anaemia. Forty-five patients were evaluable for the primary endpoint. Among them, nine patients (20%, 95% CI (10-35%)) were progression-free at 3 months. No partial response was seen, but 17 patients (36%) had stable disease (SD) as their best response. Six patients were progression-free at 6 months. CONCLUSION: Panobinostat was poorly tolerated at 40 mg thrice a week. Efficacy in unselected advanced STS was limited, although some patients had prolonged SD.
