Background: The administration of adjuvant imatinib during 3 years is indicated after resection of primary localized GIST at high risk of recurrence, but many patients relapse afterwards., Methods: IMADGIST (NCT02260505) was a multicenter, open-label, randomized phase III study evaluating the maintenance of imatinib for 3 more years (6-year arm) compared with interruption (3-year arm) from the day of randomization, conducted in the French Sarcoma Group. The primary endpoint was intent-to-treat disease-free survival. Secondary endpoints included overall survival, time to imatinib resistance, response after imatinib reintroduction at relapse, and safety., Results: From 24 December 2014 to 4 April 2023, 136 patients aged ≥18 years, Eastern Cooperative Oncology Group performance status ≤2, with a localized gastrointestinal stromal tumor with an R0 or R1 surgery, and a risk of tumor recurrence ≥35% according to National Comprehensive Cancer Network (NCCN) risk classification were randomized in 14 centers. Sixty-five patients were randomized to the 3-year arm versus 71 to the 6-year arm. There were 68 males and females. Primary sites were gastric and small bowel in 60 (44%) and 64 (47%) patients, respectively. Respectively, 52 (38%) and 71 (52%) patients had a risk of relapse of 35%-70% and >70%. With a median follow-up of 55 months (interquartile range 46-59 months) after randomization, disease-free survival was significantly superior in the 6-year arm [hazard ratio: 0.40 (0.20-0.69), P = 0.0008]. Time to imatinib resistance, survival, adverse events, and quality of life were not different in the two arms., Conclusions: Three additional years of adjuvant imatinib reduces the risk of relapse in patients who have received 3 years of adjuvant imatinib with an acceptable tolerance., (Copyright © 2024 The Authors.

Rationale: We report a phase II trial (OSAD93) testing CDDP with ifosfamide (IFO), without doxorubicin in neoadjuvant phase, in adult osteosarcoma with a 25 years follow-up., Patients and Methods: This is a multicentric phase II study of neoadjuvant chemotherapy with IFO and CDDP in localized high-grade osteosarcoma of patients. Patients received 4 pre-operative courses of IFO 9 g/m 2 and CDDP 100 mg/m 2 on day 4 (SHOC regimen), followed by local treatment. Doxorubicin was added post-operatively (HOCA regimen) in patients with > 10 % residual tumor cells. A Good Histological Response (GHR), ie ≤ 10 % residual tumor cells in > 30 % of patients, was the primary objective. Disease-free survival (DFS), overall survival (OS) and toxicity were secondary objectives., Results: From Jan 1994 to Jun 1998, 60 patients were included. Median age was 27 (range: 16-63). Primary tumor sites were limbs (76 %), trunk, head or neck (24 %). After neoadjuvant SHOC, grade 3-4 and febrile neutropenia, thrombopenia, and re-hospitalization occurred in 58 %, 17 %, 17 % and 22 % of SHOC courses and in 76 %, 28 %, 47 %, 47 % of HOCA courses, respectively. GHR was obtained in 16/60 (27.5 %) patients. With a median follow-up of 322 months, the DFS and OS were 51.8 % and 64.4 % at 5 years. At 10 years, DFS and OS were 49.9 % and 64.4 %. At 25 years, DFS and OS were 47.8 % and 55.9 %. No long-term cardiac toxicity was observed. Three patients developed a second malignancy (one fatal) after 300 months., Conclusion: Though the primary endpoint of OSAD93 was not met, this pre-operative doxorubicin-free regimen led to excellent long-term survival with limited toxicity in localized osteosarcoma., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Background: The long-term impact of tyrosine kinase inhibitor (TKI) discontinuation on resistance and survival in patients with advanced gastrointestinal stromal tumours (GIST) is unclear. We report the exploratory long-term outcomes of patients with advanced GIST stopping imatinib in the BFR14 trial., Methods: BFR14, an open-label, randomised, phase 3 trial, was done in 17 comprehensive cancer centres or hospitals across France. Patients with advanced GIST aged 18 years or older with an Eastern Cooperative Oncology Group performance status of 0-3, no previous treatment with imatinib, and no previous malignancy were eligible. Patients were treated with oral imatinib 400 mg daily. Patients with a complete or partial response, or stable disease, according to Response Evaluation Criteria in Solid Tumours (1.0) at 1 year, 3 years, and 5 years from the start of treatment were randomly assigned (1:1) to treatment discontinuation until progression (interruption group) or treatment continuation until progression (continuation group). Randomisation was done centrally with computer-generated permuted blocks of two and six patients stratified by participating centre and presence or absence of residual disease on CT scan. The primary endpoint was progression-free survival. Secondary endpoints included time to imatinib resistance and overall survival. Analyses were conducted on an intention-to-treat basis in all randomly assigned patients who were not lost to follow-up. This trial is registered with ClinicalTrial.gov, NCT00367861., Findings: Between May 12, 2003, and March 16, 2004, after 1 year of imatinib, 32 patients were randomly assigned to the interruption group and 26 to the continuation group. Between June 13, 2005, and May 30, 2007, after 3 years of imatinib, 25 patients were randomly assigned to the interruption group and 25 to the continuation group. Between Nov 9, 2007, and July 12, 2010, after 5 years of imatinib, 14 patients were randomly assigned to the interruption group and 13 to the continuation group. Median follow-up was 235·2 months (IQR 128·8-236·6) after the 1-year randomisation, 200·9 months (190·2-208·4) after the 3-year randomisation, and 164·5 months (134·4-176·4) after the 5-year randomisation. Median progression-free survival in the interruption group versus the continuation group after 1 year of imatinib was 6·1 months (95% CI 2·5-10·1) versus 27·8 months (19·5-37·9; hazard ratio [HR] 0·36 [95% CI 0·20-0·64], log-rank p=0·0003), after 3 years of imatinib was 7·0 months (3·5-11·7) versus 67·0 months (48·8-85·6; 0·15 [0·07-0·32], log-rank p<0·0001), and after 5 years of imatinib was 12·0 months (9·0-16·6) versus not reached (NR; NR-NR; 0·13 [0·03-0·58], log-rank p=0·0016). The median time to imatinib resistance after 1 year of imatinib was 28·7 months (95% CI 18·1-39·1) versus 90·6 months (25·3-156·1; HR 0·93 [95% CI 0·51-1·71], log-rank p=0·82), after 3 years was 66·2 months (43·0-89·6) versus 127·3 months (15·0-239·7; 0·35 [0·17-0·72, log-rank p=0·0028), and after 5 years was 58·6 months (0·0-167·4) versus NR (NR-NR; 0·24 [0·05-1·12], log-rank p=0·049). Median overall survival after 1 year of imatinib was 56·0 months (95% CI 30·3-82·9) versus 105·0 months (20·6-189·6; HR 0·84 [95% CI 0·46-1·54], log-rank p=0·57), after 3 years was 104·0 months (90·7-118·7) versus 134·0 months (89·7-178·3; 0·40 [0·20-0·82], log-rank p=0·0096), and after 5 years was NR (NR-NR) versus 110·4 months (82·7-154·1; 1·28 [0·41-3·99]; log-rank p=0·67), INTERPRETATION: Imatinib interruption in patients with GIST without progressive disease is not recommended. Imatinib interruption in non-progressing patients with GIST was associated with rapid progression, faster resistance to imatinib, and shorter overall survival in the long-term follow-up when compared with imatinib continuation in patients after 3 years and 5 years of imatinib., Funding: Centre Léon Bérard, INCa, CONTICANET, Ligue Contre le Cancer, and Novartis., Competing Interests: Declaration of interests J-YB reports grants from NETSARC+, INTERSARC+, and LYRICAN+ from INCA (to the institution), DEpGyn RHU and LYRICAN+ from the Agence Nationale de la Recherche (to the institution), and ERN EURACAN from the EU commission (to the institution); research support from Novartis, Deciphera, and Bayer (to the institution); membership of steering committees for the Intrigue and Motion studies for Deciphera; and membership of the supervisory boards of Transgène and Innate Pharma.

Background and Purpose: In this manuscript we describe the academic French multicentric molecular analysis platforms including PROFILER, promoted by Centre Léon Berard, and the multicentric personalized medicine trials MOST, MOST Plus and MEGAMOST., Patients/material and Methods: MOST, MOST Plus and MEGAMOST comprise 14 cohorts with different targeted agents and immunotherapies., Results and Interpretation: PROFILER has recruited 5,991 patients in 10 years, MOST and MOST Plus 875 patients since 2014 and MEGAMOST 172 patients since 2020, and are still ongoing. We provide a description of the local, national and international implications of these initiatives, and we review the results of the sorafenib and olaparib cohorts.

Background: Despite advancements in managing metastatic clear cell renal carcinoma (mccRCC) through antiangiogenic tyrosine kinase inhibitors and immunotherapy, there remains a demand for novel treatments for patients experiencing progression despite the use of these medications. There is currently no established standard treatment for patients receiving third therapy line. Prostate Specific Membrane Antigen (PSMA) whose high expression has been demonstrated in metastatic aggressive prostate adenocarcinoma is also highly expressed in neovessels of various solid tumors including renal cell carcinoma (RCC): 86% of clear cell RCC, 61% of chromophobe RCC, and 28% of papillary RCC. Therefore, PSMA may be a target expressed in metastatic ccRCC for radionuclide therapy using PSMA ligands radiolabeled with Lutetium-177 (PRLT). 177 Lu-PSMA delivers ß-particle radiation to PSMA-expressing cells and the surrounding microenvironment with demonstrated efficacy in metastatic prostate cancer., Methods: This is a multicenter phase I/II study designed to assess the tolerability and effectiveness of 177Lu-PSMA-1 in individuals with PSMA-positive metastatic clear cell renal cell carcinoma (ccRCC), identified through 68Ga-PSMA PET, conducted in France (PRadR). 48 patients will be treated with 4 cycles of 7.4 GBq of 177 Lu-PSMA-1 every 6 weeks. The primary objective is to evaluate the safety of 177 Lu-PSMA-1 (phase I) and the efficacy of 177 Lu-PSMA-1 in mccRCC patients (phase II). Primary endpoints are incidence of Severe Toxicities (ST) occurring during the first cycle (i.e. 6 first weeks) and disease Control Rate after 24 weeks of treatment (DCR24w) as per RECIST V1.1. Secondary objective is to further document the clinical activity of 177Lu-PSMA-1 in mccRCC patients (duration of response (DoR), best overall response rate (BORR), progression fee survival (PFS) and overall survival (OS)., Discussion: Our prospective study may lead to new potential indications for the use of 177 Lu-PSMA-1 in mccRCC patients and should confirm the efficacy and safety of this radionuclide therapy with limited adverse events. The use of 177 Lu-PSMA-1may lead to increase disease control, objective response rate and the quality of life in mccRCC patients., Trial Registration: ClinicalTrials.gov: NCT06059014., (© 2024.

Netrin-1 is upregulated in cancers as a protumoural mechanism 1 . Here we describe netrin-1 upregulation in a majority of human endometrial carcinomas (ECs) and demonstrate that netrin-1 blockade, using an anti-netrin-1 antibody (NP137), is effective in reduction of tumour progression in an EC mouse model. We next examined the efficacy of NP137, as a first-in-class single agent, in a Phase I trial comprising 14 patients with advanced EC. As best response we observed 8 stable disease (8 out of 14, 57.1%) and 1 objective response as RECIST v.1.1 (partial response, 1 out of 14 (7.1%), 51.16% reduction in target lesions at 6 weeks and up to 54.65% reduction during the following 6 months). To evaluate the NP137 mechanism of action, mouse tumour gene profiling was performed, and we observed, in addition to cell death induction, that NP137 inhibited epithelial-to-mesenchymal transition (EMT). By performing bulk RNA sequencing (RNA-seq), spatial transcriptomics and single-cell RNA-seq on paired pre- and on-treatment biopsies from patients with EC from the NP137 trial, we noted a net reduction in tumour EMT. This was associated with changes in immune infiltrate and increased interactions between cancer cells and the tumour microenvironment. Given the importance of EMT in resistance to current standards of care 2 , we show in the EC mouse model that a combination of NP137 with carboplatin-paclitaxel outperformed carboplatin-paclitaxel alone. Our results identify netrin-1 blockade as a clinical strategy triggering both tumour debulking and EMT inhibition, thus potentially alleviating resistance to standard treatments., (© 2023.

Purpose: Metastatic endocrine-resistant breast cancer (MBC) is a disease with poor prognosis and few treatment options. Low lymphocyte count is associated with limited overall survival. In a prospective cohort of lymphopenic patients with HER-2 negative MBC, we assessed the clinical and biological impact of pembrolizumab combined with metronomic cyclophosphamide., Experimental Design: This multicenter Phase II study evaluated the safety and clinical activity of pembrolizumab (intravenous (IV), 200mg, every 3 weeks) combined with metronomic cyclophosphamide (50mg/day, per os) in lymphopenic adult patients with HER2-negative MBC previously treated by at least one line of chemotherapy in this setting according to a Simon's minimax two-stage design. Blood and tumor samples were collected to assess the impact of the combined treatment on circulating immune cells and the tumor immune microenvironment through multiparametric flow cytometry and multiplex immunofluorescence analyses. Primary endpoint was the clinical benefit rate at 6 months of treatment (CBR-6M). Secondary endpoints were objective response rate (ORR), duration of response, progression free survival (PFS), and overall survival (OS)., Results: Two out of the twenty treated patients presented clinical benefit (one Tumor Mutational Burden (TMB)-high patient with complete response (CR) and one patient with objective response (OR) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST V1.1) associated with a strong increase of cytokine-producing and proliferating CD4 + T cells and higher CD8 + T cells to macrophage ratios in the tumor. This impact on CD4 + and CD8 + T cell polyfunctionality was still observed more than one year for the patient with CR. A decreased in their absolute number of CD4 + and CD8 + memory T cells was observed in other patients., Conclusion: Pembrolizumab combined with metronomic cyclophosphamide was well tolerated, and displayed limited anti-tumoral activity in lymphopenic MBC.

Background: Patients with cancer are at high risk of severe or lethal COVID-19. The impact of SARS-COV-2 vaccination on the risk of developing COVID-19 was investigated in an exhaustive series of patients from a comprehensive cancer center., Methods: This is a study of the exhaustive population of 2391 cancer patients who were prescribed SARS-COV-2 vaccination until 09/21. Patient characteristics, documented SARS-COV-2 infection with RT-PCR, and survival were collected. The primary endpoint was the rate of COVID-19 after vaccination. Secondary endpoints included risk factors to develop COVID-19 after vaccination, with a comparison with the cohort of vaccinated health care workers (HCW), and risk factors for death., Results: From January to September 2021, among 2391 patients with cancer under active treatment in whom a SARS-COV-2 vaccine was prescribed, 659 (28%), 1498 (63%) and 139 (6%) received 1, 2, and 3 doses, respectively. Ninety five patients received a single dose of vaccine after a previous COVID-19. Two thousand two hundred eighty five health care workers (HCW) received one (N = 17, 0.7%), 2-3 (N = 2026, 88.7%) vaccine doses and one dose after COVID-19 (N = 242, 10.6%). With a median follow-up of 142 and 199 days for patients and HCW, respectively. Thirty nine (1.6%) patients and 35 (1.5%) HCW developed COVID-19 after vaccination. Six of 39 cancer patients and no HCW died because ofCOVID-19 within 50 days after diagnosis. Independent risk factors for COVID-19 in vaccinated patients were age, single dose of vaccine without previous COVID-19 and anti-CD20 treatment in the last three months. Independent risk factors for death included metastatic disease, gender, cancer type, but also documented COVID-19 before vaccination., Conclusions: Patients receiving two or more doses of COVID-19 vaccine have reduced risk of COVID-19. The risk of death of vaccinated cancer patients presenting COVID-19 remains high. COVID-19 before vaccination is associated with an increased overall risk of death., Competing Interests: Conflict of interest statement The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: All authors: research support from Astra-Zeneca and Innate Pharma for a research program not directly related to the present work., (Copyright © 2022 Elsevier Ltd.

Cabozantinib is an inhibitor of multiple tyrosine kinases, including AXL, MET and VEGF receptors. Here, we describe the rationale and design for the phase II CaboPoint trial (ClinicalTrials.gov identifier: NCT03945773), which will evaluate the efficacy and safety of cabozantinib as a second-line treatment in patients with unresectable, locally advanced or metastatic renal cell carcinoma whose disease has progressed despite checkpoint inhibitor therapy. Patients will be recruited into two cohorts: prior ipilimumab plus nivolumab (cohort A) or prior checkpoint inhibitor-VEGF-targeted therapy (cohort B). All patients will receive once-daily oral cabozantinib 60 mg for up to 18 months. The primary end point is objective response rate. Secondary end points include overall survival, progression-free survival and safety.

It has been suggested that cancer patients are at higher risk of contracting COVID-19 and at higher risk of developing a severe form of the disease and fatality. This study's objectives were to measure the excess risk of mortality and morbidity of patients with cancer among patients hospitalized for a SARS-CoV-2 infection, and to identify factors associated with the risk of death and morbidity among cancer patients. All first cancer patients hospitalized for COVID-19 in the two main hospitals of the Lyon area were included. These patients were matched based on age, gender, and comorbidities with non-cancer control patients. A total of 108 cancer patients and 193 control patients were included. The severity at admission and the symptoms were similar between the two groups. The risk of early death was higher among cancer patients, while the risk of intubation, number of days with oxygen, length of stay in ICU, and length of hospital stay were reduced. The main factors associated with early death among cancer patients was the severity of COVID-19 and the number of previous chemotherapy lines. The outcomes appear to be driven by the severity of the infection and therapeutic limitations decided at admission.

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., Competing Interests: Disclosure JYB reports research support and honoraria from Troche, BMS, MSD, PharmaMar, Bayer, Deciphera, GSK, Novartis, and AstraZeneca.

NK cells are cytotoxic lymphocytes displaying strong antimetastatic activity. Mouse models and in vitro studies suggest a prominent role of the mechanistic target of rapamycin (mTOR) kinase in the control of NK cell homeostasis and antitumor functions. However, mTOR inhibitors are used as chemotherapies in several cancer settings. The impact of such treatments on patients' NK cells is unknown. We thus performed immunophenotyping of circulating NK cells from metastatic breast cancer patients treated with the mTOR inhibitor everolimus over a three-month period. Everolimus treatment resulted in inhibition of mTORC1 activity in peripheral NK cells, whereas mTORC2 activity was preserved. NK cell homeostasis was profoundly altered with a contraction of the NK cell pool and an overall decrease in their maturation. Phenotype and function of the remaining NK cell population was less affected. This is, to our knowledge, the first in vivo characterization of the role of mTOR in human NK cells., (Copyright © 2021 by The American Association of Immunologists, Inc.)

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., Competing Interests: Disclosure DP: research grant: MSDAVENIR; honoraria: Roche, BMS, MSD, AstraZeneca; travel: AstraZeneca.

Background: There is a growing need for real-world data on cancer treatments usage, especially to assess compliance with recommendations. We developed a French project using hospital data to analyse evolution in the therapeutic strategies implemented in patients with human epidermal growth factor receptor 2 (HER2)-overexpressed (HER2+) breast cancer (BC) and exposed to injectable HER2-targeted therapies, i.e. trastuzumab, pertuzumab or trastuzumab emtansine (T-DM1)., Patients and Methods: Data from 26,350 women with BC were extracted in September 2018 from the Electronic Pharmacy Record systems of 120 French randomly recruited hospitals. Evolution in the treatments used, and combination regimens were described from 2011, in accordance with the BC stage and treatment line., Results: Overall, 21,119 patients treated since 2011 were analysed: 16,398 patients with early BC (eBC) and 6030 patients with metastatic BC (mBC) including patients treated at both stages. In eBC, 89.2% of patients received trastuzumab combined with at least taxanes (trastuzumab-taxane-anthracycline: 62.6%). Patients with mBC were treated in the first line (80.3%) and/or the second line (40.1%) and/or ≥ the third line (28.3%). After its approval in 2014, pertuzumab was first used in first-line therapy combinations in 67.4% of the total cases, while trastuzumab-taxane decreased from 47.2% to 9.2%. Similarly, T-DM1 was used as the second-line treatment in 53.8% of cases., Conclusions: Given recent changes in available treatments for patients with HER2+ BC, this large French project provides robust information on real-world evolution in therapeutic strategies. Our data suggest there is room for significant improvement in optimal drug utilisation. Such data will be useful to build drug-related indicators for future value-based pricing solutions., Competing Interests: Conflict of interest statement PC reports grants, personal fees and non-financial support from Roche during the conduct of the study; grants, personal fees and non-financial support from Pfizer; grants from Novartis; and personal fees from Lilly outside the submitted work.

Purpose: The Program to Establish the Genetic and Immunologic Profile of Patient's Tumor for All Types of Advanced Cancer study (ClinicalTrials.gov identifier: NCT01774409) analyzed the genome of refractory cancers to identify a potential molecular-based recommended therapy (MBRT). The objectives of the pediatric substudy were to describe the incidence of genomic mutations, the MBRT, and the treatments undertaken with a molecular-targeted agent in a pediatric cohort., Methods: The tumor genome was analyzed within a 69-gene next-generation sequencing panel and an array comparative genomic hybridization assay. The results were evaluated by a multidisciplinary molecular board, and the targeted therapies were provided in the setting of a clinical trial or through compassionate use programs, when indicated., Results: Between November 2013 and June 2017, 50 patients younger than 19 years who were treated for a high-risk or relapsing tumor were included. Sarcomas (n = 24; 47%), CNS tumors (n = 14; 29%), and neuroblastomas (n = 5; 10%) were the most frequent tumor subtypes. Seven patients (14%) were excluded because no DNA could be recovered. Among the 43 remaining patients, 10 exhibited at least one targetable genomic alteration. Ultimately, four patients (8%) were treated with the recommended targeted therapy., Conclusion: The results of this study confirm treatment with a targeted therapy for pediatric patients with cancer is still limited at present, as also is reported for adults.

Background: Cancer patients presenting with COVID-19 have a high risk of death. In this work, predictive factors for survival in cancer patients with suspected SARS-COV-2 infection were investigated., Methods: PRE-COVID-19 is a retrospective study of all 302 cancer patients presenting to this institute with a suspicion of COVID-19 from March 1st to April 25th 2020. Data were collected using a web-based tool within electronic patient record approved by the Institutional Review Board. Patient characteristics symptoms and survival were collected and compared in SARS-COV-2 real-time or reverse-transcriptase PCR (RT-PCR)-positive and RT-PCR-negative patients., Results: Fifty-five of the 302 (18.2%) patients with suspected COVID-19 had detectable SARS-COV-2 with RT-PCR in nasopharyngeal samples. RT-PCR-positive patients were older, had more frequently haematological malignancies, respiratory symptoms and suspected COVID-19 pneumonia of computed tomography (CT) scan. However, respectively, 38% and 20% of SARS-COV-2 RT-PCR-negative patients presented similar respiratory symptoms and CT scan images. Thirty of the 302 (9.9%) patients died during the observation period, including 24 (80%) with advanced disease. At the median follow-up of 25 days after the first symptoms, the death rate in RT-PCR-positive and RT-PCR-negative patients were 21% and 10%, respectively. In both groups, independent risk factors for death were male gender, Karnofsky performance status <60, cancer in relapse and respiratory symptoms. Detection of SARS-COV-2 on RT-PCR was not associated with an increased death rate (p = 0.10). None of the treatment given in the previous month (including cytotoxics, PD1 Ab, anti-CD20, VEGFR2…) correlated with survival. The survival of RT-PCR-positive and -negative patients with respiratory symptoms and/or COVID-19 type pneumonia on CT scan was similar with a 18.4% and 19.7% death rate at day 25. Most (22/30, 73%) cancer patients dying during this period were RT-PCR negative., Conclusion: The 30-day death rate of cancer patients with or without documented SARS-COV-2 infection is poor, but the majority of deaths occur in RT-PCR-negative patients., Competing Interests: Conflict of interest statement The authors declare no conflict of interest., (Copyright © 2020 The Author(s).

Background/aim: Vinorelbine is indicated for use in the treatment of MBC as a single agent or in combination but there is little real world data on this molecule and even less on its oral form. We exploited the Unicancer Epidemiology Strategy Medical-Economics (ESME) metastatic breast cancer (MBC) database to investigate current patterns of use of oral vinorelbine (OV), as well as outcomes of patients receiving this drug., Patients and Methods: Data were collected retrospectively from women and men treated for MBC between 2008 and 2014 at one of 18 French Comprehensive Cancer Centres. The efficacy of OV was evaluated in terms of progression-free (PFS) and overall survival (OS) and treatment duration. The population and patterns of OV usage were also described., Results: A total of 1806 patients (11% of the ESME MBC database) were included in this analysis. OV was prescribed as monotherapy (46%) or in combination (29%), especially with capecitabine. mainly in later treatment lines. Median PFS was 3.3 months: 2.9 months for single agent, 3.6 months for combination therapy. Median OS was 40.9 months., Conclusion: Real-world data offer complementary results to the data from traditional clinical trials, but they concern a much larger population. In this ESME MBC cohort, OV was only prescribed to a small subset of MBC patients. OV was mainly given as single agent to patients with heavily pre-treated MBC; less commonly, it was co-administered with capecitabine or anti-HER2, in earlier lines of therapy. PFS was modest but in line with previous reports., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

Rationale: CSF1R tyrosine kinase inhibitors (TKI) and antibodies yield response rates and tumor control in patients with diffuse type tenosynovial giant cell tumors (dTGCT). The long term management of patients with dTGCT treated with TKI is however not known., Patients and Methods: We conducted a retrospective single center study on the 39 patients with advanced and/or inoperable dTGCT referred to the Centre Leon Berard for a medical treatment. The clinical characteristics and treatments of patients who had received at least one line of CSF1R TKI or Ab was collected from the electronic patient records and analyzed, after this study was approved by the Institutional Review Board of the Centre Leon Berard. Statistics were conducted using SPSS 23.0., Results: Thirty-nine patients received at least one line of TKI among the 101 patients with histologically confirmed dTGCT refered to this center. Imatinib, nilotinib, pexidartinib, emactuzumab were the most frequently used agents. First line treatment was given for a median duration of 7 months. With a median follow-up from the initiation of TKI of 30 months, the progression-free rate at 30 months is 56% for the 39 patients. 15 patients had recurrent disease after first line CSF1R inhibitor: 12 (80%) received a 2nd line treatment for a median duration of 6 months and a median time to progression (TTP) of 12 months. Six patients had afterwards a recurrent disease and 5 (83%) received a 3rd line treatment for a median duration of 5 months and a median TTP of 9 months. Progression-free rate at 30 months was observed in 3 of 12 (25%) after line 2 and 1 of 5 (20%) after line 3. None of the patients refered died with a median follow-up of 67 months., Conclusions: CSF1R TKI or Ab provide prolonged tumor control and symptom relief for a majority of patients with inoperable or relapsing dTGCT, in first and subsequent lines. Multiple lines are required for close to 50% of patients with relapsing dTGCT., Competing Interests: JYB: research support and honoraria from Novartis, Roche, Five Prime, Plexxikon, Daiichi Sankyo, Deciphera.

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 < 0.0001) with a median OS of 43.3 (95% CI, 42.5-44.5) in HR+/HER2-; 50.1 (95% CI, 47.6-53.1) in HER2+; and 14.8 months (95% CI, 14.1-15.5) in triple-negative subgroups, respectively. Beyond performance status, the following variables had a constant significant negative prognostic impact on OS in the whole cohort and among subtypes: older age at diagnosis of metastases (except for the triple-negative subtype), metastasis-free interval between 6 and 24 months, presence of visceral metastases and number of metastatic sites ≥ 3., 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.

Today, the only potentially curative option in patients with colorectal liver metastases is surgery. However, liver resection is feasible in less than 20% of patients. Surgery has been widely used in association with radiofrequency, cryotherapy, or microwaves to expand the number of treatments performed with a curative intent. Nevertheless, several limitations have been documented when using these techniques (i.e., a traumatic puncture of the parenchyma, a limited size of lesions, and an inability to monitor the treatment in real-time).High-intensity focused ultrasound (HIFU) technology can achieve precise ablations of biological tissues without incisions or radiation. Current HIFU devices are based on an extracorporeal approach with limited access to the liver. We have developed a HIFU device designed for intraoperative use. The use of a toroidal transducer enables an ablation rate (10 cm 3 ·min -1 ) higher than any other treatment and is independent of perfusion. The feasibility, safety, and accuracy of intraoperative HIFU ablation were evaluated during an ablate-and-resect prospective study. This clinical phase I and IIa study was performed in patients undergoing hepatectomy for liver metastases. The HIFU treatment was performed on healthy tissue scheduled for resection.Liver metastases measuring less than 20 mm will be targeted during phase IIb (currently ongoing). This set-up allows the real-time evaluation of HIFU ablation while protecting participating patients from any adverse effects related to this new technique. Fifteen patients were included in phase I-IIa and 30 HIFU ablations were safely created within 40 s and with a precision of 1-2 mm. The average dimensions of the HIFU ablations were 27.5 x 21.0 mm 2 , corresponding to a volume of approximately 7.5 cm 3 . The aim of the ongoing phase IIb is to ablate metastases of less than 20 mm in diameter with a 5 mm margin.

Background: Nucleolin (NCL) is a multifunctional protein with oncogenic properties. Anti-NCL drugs show strong cytotoxic effects, including in triple-negative breast cancer (TNBC) models, and are currently being evaluated in phase II clinical trials. However, few studies have investigated the clinical value of NCL and whether NCL stratified cancer patients. Here, we have investigated for the first time the association of NCL with clinical characteristics in breast cancers independently of the different subtypes. Methods: Using two independent series ( n = 216; n = 661), we evaluated the prognostic value of NCL in non-metastatic breast cancers using univariate and/or multivariate Cox-regression analyses. Results: We reported that NCL mRNA expression levels are markers of poor survivals independently of tumour size and lymph node invasion status ( n = 216). In addition, an association of NCL expression levels with poor survival was observed in TNBC ( n = 40, overall survival (OS) p = 0.0287, disease-free survival (DFS) p = 0.0194). Transcriptomic analyses issued from The Cancer Genome Atlas (TCGA) database ( n = 661) revealed that breast tumours expressing either low or high NCL mRNA expression levels exhibit different gene expression profiles. These data suggest that tumours expressing high NCL mRNA levels are different from those expressing low NCL mRNA levels. Conclusions: NCL is an independent marker of prognosis in breast cancers. We anticipated that anti-NCL is a promising therapeutic strategy that could rapidly be evaluated in high NCL -expressing tumours to improve breast cancer management.

Aim: 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., Methods: 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., Results: 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)., Conclusions: 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., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Background and Objectives: Fluorescence imaging using indocyanine green (ICG) is undergoing extensive development. This study aimed to assess the merits of ICG in regard to hepatic surgery., Methods: Patients with liver lesions that required a resection were eligible. They received an injection of ICG the day before the surgery. Step 1 allowed assessment of use of the medical device under surgical conditions. Steps 2 and 3 assessed the capacity of the MD to detect known tumorous lesions and to spot a predefined area of the liver following injection of ICG into the portal vein (ICGp)., Results: The 1st step allowed for validation of the MD use with three patients. Between 04-2013 and 04-2015, 45 pts were included (40 eligible) in steps 2 and 3. All of the tumorous lesions (95/119) exhibited fluorescence. Four new metastasis were detected in 3 pts, and two missing metastases in 1 pt. False positive were 22%. The maximal depth for detection by fluorescence was 13 mm. Injection of ICGp allowed the corresponding anatomical area to be identified in 16/20 patients., Conclusion: This study confirmed that intraoperative fluorescence is a helpful and relevant tool for the liver surgeon (NCT 01738217)., (© 2018 Wiley Periodicals, Inc.)

Backround: Radiolabeled OTSA101, a monoclonal antibody targeting synovial sarcoma (SS) developed by OncoTherapy Science, was used to treat relapsing SS metastases following a theranostic procedure: in case of significant 111 In-OTSA101 tumor uptake and favorable biodistribution, patient was randomly treated with 370/1110 MBq 90 Y-OTSA101. Monte Carlo-based 3D dosimetry integrating time-activity curves in VOI was performed on 111 In-OTSA101 repeated SPECT/CT. Estimated absorbed doses (AD) in normal tissues were compared to biological side effects and to the admitted maximal tolerated absorbed dose (MTD) in normal organs. Results in the tumors were also compared to disease evolution., Results: Biodistribution and tracer quantification were analyzed on repeated SPECT/CT acquisitions performed after injection of 111 In-OTSA101 in 19/20 included patients. SPECT images were warped to a common coordinates system with deformable registration. Volumes of interest (VOI) for various lesions and normal tissues were drawn on the first CT acquisition and reported to all the SPECT images. Tracer quantification and residence time of 111 In-OTSA101 in VOI were used to evaluate the estimated absorbed doses per MBq of 90 Y-OTSA101 by means of Monte Carlo simulations (GATE). A visual scale analysis was applied to assess tumor uptake (grades 0 to 4) and results were compared to the automated quantification. Results were then compared to biological side effects reported in the selected patients treated with 90 Y-OTSA101 but also to disease response to treatment. After screening, 8/20 patients were treated with 370 or 1110 MBq 90 Y-OTSA101. All demonstrated medullary toxicity, only one presented with transient grade 3 liver toxicity due to disease progression, and two patients presented with transient grade 1 renal toxicity. Median absorbed doses were the highest in the liver (median, 0.64 cGy/MBq; [0.27 -1.07]) being far lower than the 20 Gy liver MTD, and the lowest in bone marrow (median, 0.09 cGy/MBq; [0.02 -0.18]) being closer to the 2 Gy bone marrow MTD. Most of the patients demonstrated progressive disease on RECIST criteria during patient follow-up. 111 In-OTSA101 tumors tracer uptake visually appeared highly heterogeneous in inter- and intra-patient analyses, independently of tumor sizes, with variable kinetics. The majority of visual grades corresponded to the automated computed ones. Estimated absorbed doses in the 95 supra-centimetric selected lesions ranged from 0.01 to 0.71 cGy per injected MBq (median, 0.22 cGy/MBq). The maximal tumor AD obtained was 11.5 Gy., Conclusions: 3D dosimetry results can explain the observed toxicity and tumors response. Despite an intense visual 111 In-OTSA101 liver uptake, liver toxicity was not the dose limiting factor conversely to bone marrow toxicity. Even though tumors 111 In-OTSA101 avidity was visually obvious for treated patients, the low estimated tumors AD obtained by 3D dosimetry explain the lack of tumor response.

Background: Breast cancer (BC) patients with comparable prognostic features have heterogeneous outcomes, party related to a possible radiotherapy resistance leading to local-regional recurrences (LRR). The objective of the present study was to identify predictive molecular biomarkers of LRR of BC., Patients and Methods: Genetic profile of 146 BC patients' tumours included in the ProfiLER clinical trial (NC01774409) between 2013 and 2016 were analysed using next-generation-sequencing and comparative-genomic-hybridization tests. Patients and tumour characteristics were retrospectively collected and analysed for association with genomic rearrangements (mutations, amplification, deletions). Only gene alterations observed in >3% of the tumours were selected., Results: A total of 193 genomic rearrangements were identified, and 16 were observed in >3% of tumours. One was statistically correlated to the risk of local relapse. A median loco-regional progression-free survival (LRPFS) of 23.6 years was reported for PIK3CA mutation carriers (n = 31, 21.2%) versus 9.9 years for PIK3CA wild-type patients (HR 0.27, 95% CI 0.12-0.65, P = 0.002 in univariate analysis). PIK3CA mutation was identified as an independent protective factor on LRR using multivariate analysis (HR 0.29, 95% CI 0.09-0.99, P = 0.047). All other mutations, amplifications or deletions were not found associated with LRPFS., Conclusion: PIK3CA mutation was associated with a lower risk of local relapse in this population of BCs. This is consistent with recent studies suggesting PIK3CA to be part of biological pathways impacting the radiosensitivity., (© The Author 2017.

Background: The International organization for standardization (ISO) is the world leader in providing industrial and commercial standards and certifications. Beyond medical devices, four French clinical research and innovation departments have received an ISO 9001 certification (the standard for quality management). Simultaneously, medico-economic studies have become increasingly important in the public decision process. Using the clinical research and innovation department from the Léon-Bérard Cancer Center as an example, the purpose of this article is to show how the scope of the ISO 9001 certification has been extended to cover medico-economic studies., Method: All of the processes, procedures, operating modes, documents, and indicators used by the clinical research and innovation department of the Léon-Bérard center were investigated. Literature searches were conducted using Medline keywords. The recommendations from the French national authority for health and other organizations, such as the International society for pharmacoeconomics and outcomes research (ISPOR), were also considered, as well as the recommendations of the General inspectorate of social affairs., Results: In accordance with the national and international recommendations, two procedures were created and four procedures were revised at this center. Five indicators of quality and an evaluation chart were developed., Conclusion: By adopting the ISO 9001 certification into its medico-economic studies, the clinical research and innovation department of the Léon-Bérard center has used an innovative approach in the context of the growing importance of economic studies in decision-making., (Copyright © 2017 Elsevier Masson SAS.

Purpose: To report the long-term results of the French Genitourinary Study Group (GETUG)-01 study in terms of event-free survival (EFS) and overall survival (OS) and assess the potential interaction between hormonotherapy and pelvic nodes irradiation., Patients and Methods: Between December 1998 and June 2004, 446 patients with T1b-T3, N0pNx, M0 prostate carcinoma were randomly assigned to either pelvic nodes and prostate or prostate-only radiation therapy. Patients were stratified into 2 groups: "low risk" (T1-T2 and Gleason score 6 and prostate-specific antigen <3× the upper normal limit of the laboratory) (92 patients) versus "high risk" (T3 or Gleason score >6 or prostate-specific antigen >3× the upper normal limit of the laboratory). Short-term 6-month neoadjuvant and concomitant hormonal therapy was allowed only for high-risk patients. Radiation therapy was delivered with a 3-dimensional conformal technique, using a 4-field technique for the pelvic volume (46 Gy). The total dose recommended to the prostate moved from 66 Gy to 70 Gy during the course of the study. Criteria for EFS included biologic prostate-specific antigen recurrences and/or a local or metastatic progression., Results: With a median follow-up of 11.4 years, the 10-year OS and EFS were similar in the 2 treatment arms. A higher but nonsignificant EFS was observed in the low-risk subgroup in favor of pelvic nodes radiation therapy (77.2% vs 62.5%; P=.18). A post hoc subgroup analysis showed a significant benefit of pelvic irradiation when the risk of lymph node involvement was <15% (Roach formula). This benefit seemed to be limited to patients who did not receive hormonal therapy., Conclusion: Pelvic nodes irradiation did not statistically improve EFS or OS in the whole population but may be beneficial in selected low- and intermediate-risk prostate cancer patients treated with exclusive radiation therapy., (Copyright © 2016 Elsevier Inc.

A better understanding of the dynamics of molecular changes occurring during the early stages of oral tumorigenesis may help refine prevention and treatment strategies. We generated genome-wide expression profiles of microdissected normal mucosa, hyperplasia, dysplasia and tumors derived from the 4-NQO mouse model of oral tumorigenesis. Genes differentially expressed between tumor and normal mucosa defined the "tumor gene set" (TGS), including 4 non-overlapping gene subsets that characterize the dynamics of gene expression changes through different stages of disease progression. The majority of gene expression changes occurred early or progressively. The relevance of these mouse gene sets to human disease was tested in multiple datasets including the TCGA and the Genomics of Drug Sensitivity in Cancer project. The TGS was able to discriminate oral squamous cell carcinoma (OSCC) from normal oral mucosa in 3 independent datasets. The OSCC samples enriched in the mouse TGS displayed high frequency of CASP8 mutations, 11q13.3 amplifications and low frequency of PIK3CA mutations. Early changes observed in the 4-NQO model were associated with a trend toward a shorter oral cancer-free survival in patients with oral preneoplasia that was not seen in multivariate analysis. Progressive changes observed in the 4-NQO model were associated with an increased sensitivity to 4 different MEK inhibitors in a panel of 51 squamous cell carcinoma cell lines of the areodigestive tract. In conclusion, the dynamics of molecular changes in the 4-NQO model reveal that MEK inhibition may be relevant to prevention and treatment of a specific molecularly-defined subgroup of OSCC., Competing Interests: All authors disclose any potential conflicts of interest.

Validated predictive biomarkers for multi-tyrosine kinase inhibitors (MTKI) efficacy are lacking. We hypothesized that interindividual response variability is partially dependent on somatic DNA copy number alterations (SCNAs), particularly those of genes encoding the protein tyrosines targeted by MTKI (called target genes). Genomic alterations were investigated in MTKI responsive and non responsive patients with different histological subtypes included in the ProfiLER protocol (NCT 01774409). From March 2013 to August 2014, 58 patients with advanced cancer treated with one of 7 MTKIs were included in the ProfiLER trial and split into one discovery cohort (n = 13), and 2 validation cohorts (n = 12 and 33). An analysis of the copy number alterations of kinase-coding genes for each of 7 MTKIs was conducted. A prediction algorithm (SUMSCAN) based on the presence of specific gene gains (Tumor Target Charge, TTC) and losses (Tumor Target Losses, TTL) was conceived and validated in 2 independent validation cohorts. MTKI sensitive tumors present a characteristic SCNA profile including a global gain profile, and specific gains for target genes while MTKI resistant tumors present the opposite. SUMSCAN favorable patients achieved longer progression-free and overall survival. This work shows that the copy number sum of kinase-coding genes enables the prediction of response of cancer patients to MTKI, opening a novel paradigm for the treatment selection of these patients.

Background: Cancer patients with CD4 lymphopenia have an increased risk of severe toxicity after administration of cytotoxic chemotherapy. The impact of CD4 lymphopenia on long term overall survival (OS) of cancer patients was explored in this work., Patients and Methods: The first prospective series (test series) included 219 patients with solid tumours, lymphomas or myelomas receiving chemotherapy within an oncology department in 1999 and 2000. A phenotypic analysis of lymphocyte subsets by flow cytometry was performed before chemotherapy on day 1. The prognostic value of total, CD4, CD8 and CD56 lymphocyte count for OS was tested in a multivariate analysis. The prognostic value of low CD4 counts was then tested in a validation series of 269 patients with metastatic solid tumours in second line treatment included in a prospective observational study in the Centre Leon Berard., Results: In the test series, all patients with metastatic cancers and CD4 lymphopenia ≤ 200/μL (12% of metastatic patients) died within 18 months with a median OS of 5.9 months. CD4 count was an independent prognostic factor for OS and PFS in multivariate analysis. In the validation series, 83 (30%) of patients had CD4 count ≤ 200/μL: their median overall survival was 3.9 months with an 18-month survival rate of 6%. CD4 count was also an independent prognostic factor for overall survival in this series., Conclusions: CD4 lymphopenia <200/μL is frequent in advanced cancer patients and associated with a very short life expectancy. These patients should be proposed for specific treatment and research approaches., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Aim: Carbonic anhydrase 9 (CA9) has been found to be one of most powerful biomarkers for clear-cell renal cell carcinoma (RCC). The serum CA9 is detectable. The aim of this study was to evaluate the potential prognostic role of serum CA9 in patients with metastatic clear-cell RCC patients under targeted therapy., Patients and Methods: Serum samples came from the randomized phase 2 TORAVA trial. All patients received a targeted therapy (arm A designed as experimental group: temsirolimus and bevacizumab combination; arm B: sunitinib; arm C: interferon-alfa and bevacizumab). Seventy cases of metastatic clear-cell RCC were analyzed. There were 49 males and 21 females. The age ranged from 33.5 to 79.1 years with a median of 61.2 years. Serum samples were collected before treatment. Serum CA9 was quantified by enzyme-linked immunosorbent assay (ELISA). The correlation of the serum CA9 levels with the clinical parameters, treatment response and overall survival was analyzed. Overall survival estimates were calculated using the Kaplan-Meier method and compared by the log-rank test., Results: Serum concentrations of CA9 ranged between 0 and 897.3 pg/ml, with an average of 94.4±176.6 pg/ml. There was no association between serum CA9 and clinical parameters such as Eastern Cooperative Oncology Group (ECOG) Performance Status (p=0.367) or Motzer classification (p=0.431). The serum CA9 levels were lower in the response group (64.7±104.7 pg/ml) than the no-response group (108.2±203.8 pg/ml), but the difference was not statisticlly significant (p=0.366). For the patient group overall, the Kaplan-Meier survival curve showed that high serum CA9 levels were significantly associated with shorter overall survival (hazard ratio=2.65, 95% confidence interval=1.19-5.92, log-rank test p=0.0136). For the major group of patients treated with temsirolimus and bevacizumab, the Kaplan-Meier survival curve showed that high serum CA9 levels were significantly associated with shorter overall survival (p=0.0006)., Conclusion: Serum CA9 levels may be of clinical interest to predict the outcome for patients under targeted therapy for metastatic clear-cell RCC. CA9 may be used to select patients with metastatic clear cell RCC for clinical trials.

Lymphopenia (< 1Giga/L) detected before initiation of chemotherapy is a predictive factor for death in metastatic solid tumors. Combinatorial T cell repertoire (TCR) diversity was investigated and tested either alone or in combination with lymphopenia as a prognostic factor at diagnosis for overall survival (OS) in metastatic breast cancer (MBC) patients. The combinatorial TCR diversity was measured by semi quantitative multi-N-plex PCR on blood samples before the initiation of the first line chemotherapy in a development (n = 66) and validation (n = 67) MBC patient cohorts. A prognostic score, combining lymphocyte count and TCR diversity was evaluated. Univariate and multivariate analyses of prognostic factors for OS were performed in both cohorts. Lymphopenia and severe restriction of TCR diversity called "divpenia" (diversity ≤ 33%) were independently associated with shorter OS. Lympho-divpenia combining lymphopenia and severe divpenia accurately identified patients with poor OS in both cohorts (7.6 and 10.6 vs 24.5 and 22.9 mo). In multivariate analysis including other prognostic clinical factors, lympho-divpenia was found to be an independent prognostic factor in the pooled cohort (p = 0.005) along with lack of HER2 and hormonal receptors expression (p = 0.011) and anemia (p = 0.009). Lympho-divpenia is a novel prognostic factor that will be used to improve quality of MBC patients' medical care.

Purpose: The primary objective of this study was to compare the levels of environmental contamination before and after the introduction of PhaSeal® (closed-system drug transfer device) in two hospital pharmacies. Our secondary objective was to assess the impact of the device on the duration of drug preparation compared to procedures involving the use of needles and syringes., Methods: The study involved two French hospitals, which prepared antineoplastic chemotherapy using a biological safety cabinet and an isolator. Five skilled pharmacy technicians at each hospital prepared a total of 100 chemotherapy preparations using the standard procedure and 100 using the PhaSeal® system. To control for possible contamination occurring in the course of the procedure, we used fluorescein which becomes fluorescent when exposed to UV light. To reply the second objective, we timed the duration of the different steps of the manipulation., Results: Our findings showed a major reduction in the contamination of the work environment when using the PhaSeal® system for drug preparation. Reduction rates higher than 93% were obtained, whatever the type of protection used. On the duration of preparation, our results indicate that this duration would be approximately 1 h longer for the preparation of 100 samples., Conclusion: In conclusion, this study clearly establishes the benefit of using PhaSeal® for protecting the staff members who work with hazardous agents. It also indicates that the duration of drug preparation is not impacted by the use of the system.

Background: In the evolution of metastatic castration-resistant prostate cancer (mCRPC), patients present visceral metastases with or without neuroendocrine differentiation in 20% of cases., Patients and Methods: We assessed the efficacy and toxicity of a platinum-based chemotherapy regimen in mCRPC patients with either neuroendocrine differentiation defined by high serum levels of chromogranin A (CgA) and neuron-specific enolase (NSE) or visceral metastases. Patients received the combination of carboplatin and etoposide every 3 weeks. Efficacy end points included prostate-specific antigen (PSA) and neuroendocrine marker response, objective response and toxicity., Results: Of the 60 patients included from April 2005 to January 2008, 78.6% had bone metastases, 46.4% had lymph node involvement and 57.1% had liver and/or lung localizations. The objective response rate was 8.9% in the 46 patients with measurable disease. A neuroendocrine response was observed in 31% of cases for NSE and 7% for CgA. The PSA response rate was 8%. The most common grade 3-4 treatment-related toxic effects were neutropenia (65.5%), thrombocytopenia (32.7%) and anemia (27.3%). There was 7.2% febrile neutropenia, with one toxicity-related death. The median follow-up was 9.3 months [95% confidence interval (CI) 0.2-27.1] and the median overall survival 9.6 months (95% CI 8.7-12.7)., Conclusion: The benefit-risk ratio of this regimen seems unfavorable due to poor response and high toxicity.

Although new chemotherapeutic drugs for metastatic breast cancer (MBC) have been approved over the past decade, it is unclear whether this has changed the overall outcome of patients. This study assessed the clinical and economic impacts of these drugs. We retrospectively studied MBC patients receiving chemotherapy in our institution over two time periods, 1994-1998 and 2003-2006. Patient characteristics and outcomes, and treatment characteristics and costs (€, 2008) were compared. Three hundred and one patients were identified, 149 patients in the first cohort and 152 in second one. The median number of lines of chemotherapy was similar in the two cohorts (three lines). The median costs of chemotherapy per patient nearly doubled over time, from 6,272 € in the 1994-1998 cohort to 13,035 € in the 2003-2006 cohort (P < 0.001). No survival difference was observed between the two groups, with a 3-year survival rate estimated to 41% in the 1994-1998 cohort and 44% in the 2003-2006 cohort (P = 0.52). In multivariate analysis, prognostic factors associated with longer overall survival were single metastatic site (HR 0.48; P < 10⁻³), bone metastases (HR = 0.67; P = 0.007) and positive hormone receptors (HR 0.56; P = 0.0002). New chemotherapeutic agents induced a significant cost increase over time. The limited size and heterogeneity of our cohort do not allow any conclusion concerning their impact on survival.

Background: Imatinib evaluated as a new treatment option in patients with recurrent or established progressive aggressive fibromatosis/desmoid tumor (AF/DT)., Patients and Methods: Forty patients with unresectable and progressive symptomatic AF/DT were treated with imatinib (400 mg/day for 1 year) in a Simon's optimal two-stage phase II study (P(0) = 10%, P(1) = 30%, α = 5%, β = 10%). The primary end point was non-progressive at 3 months (RECIST)., Results: The study population consisted of 28 women and 12 men, with a mean age of 41 (range 20-72 years). Most of the primary sites were extra-abdominal (24, 54.5%). Familial adenomatous polyposis was observed in six (15%) cases. The median follow-up was 34 months. Imatinib toxicity was similar to that previously reported in literature. Tumor assessment was validated by a central independent radiology committee for 35 patients At 3 months, one (3%) complete and three (9%) partial confirmed responses were observed. The non-progression rates at 3, 6 and 12 months were, respectively, 91%, 80% and 67%. The 2-year progression-free and overall survival rates were 55% and 95%, respectively. Two patients with mesenteric AF/DT died from progressive disease., Conclusion: Imatinib is active in the treatment of recurrent and progressive AF/DT, providing objective response and long-term stable disease in a large proportion of patients.

Objective: Telomeres are protected by tightly regulated factors and elongated by telomerase. Short and/or deprotected chromosomes are recombinogenic and thereby cancer prone., Materials and Methods: Together with the quantification of telomerase activity (TA), measuring telomere length (TL) and expression of the genes that govern telomere protection and elongation are useful for assessing telomere homeostasis., Results: By these means we demonstrate that TL, hTERT, and TA are in the order acute myelogenous leukemia (AML) > T-cell acute lymphoblastic leukemia (T-ALL) > B-cell acute lymphoblastic leukemia (B-ALL) > T-ALL > AML, and B-ALL > AML > T-ALL. AML0 and AML3 display the lowest amounts of hTERT transcripts, and ALL and AML cells with cytogenetic abnormalities possess the shortest telomeres. hTERT expression includes phenotype-specific RNA maturation and correlates with TA but not with TL. A wide ratio of TA to hTERT expression between leukemia subtypes suggests phenotype-specific hTERT post-transcriptional deregulations. B- and T-ALL overexpress Ku70 and Pinx1, T-ALL PTOP and RAP1, and B-ALL TRF2, the expression of which is significantly higher in cases with abnormal karyotype. hTERT transcription and TL correlate with response to intensive chemotherapy, and hTERT and RAD50 are independent prognostic factors for survival., Conclusions: Each leukemia subtype possesses specific telomere dysregulations that rely on phenotype, karyotype, response to treatment, and survival., (Copyright © 2011 Published by Elsevier Inc.)

Objective: To assess the efficacy of capecitabine plus docetaxel (XT) versus epirubicin plus docetaxel (ET) as first-line therapy for metastatic breast cancer (MBC)., Patients and Methods: Patients with no prior chemotherapy for MBC were randomized to 3-weekly cycles of either XT (capecitabine 1,000 mg/m(2) twice daily, days 1-14; docetaxel 75 mg/m(2), day 1) or ET (epirubicin 75 mg/m(2), day 1; docetaxel 75 mg/m(2), day 1). The primary endpoint was non-progression rate 6 months after randomization. The planned sample size was 106 patients based on a randomized, phase II selection design., Results: Between April 2004 and January 2007, 68 patients were randomized, giving 82% power to select the best regimen according to a 6-month non-progression rate. Slow accrual led to premature study termination. Baseline characteristics were generally well balanced between arms. The 6-month non-progression rates were 75.8% with XT versus 65.7% with ET (p = 0.36). After 42 months' median follow-up, median progression-free survival was 12.4 versus 6.8 months, respectively (p = 0.040). The safety profiles were consistent with previous experience., Conclusion: Further larger studies are warranted to validate these results. Despite more grade 3 hand-foot syndrome, first-line XT may be a valid alternative to ET, potentially improving efficacy., (Copyright © 2011 S. Karger AG, Basel.)

Background: Imatinib induces responses and disease stabilisations in non-resectable patients with aggressive fibromatosis (AF). The precise target of imatinib in AF and predictive factors for response to treatment are unknown., Methods: We investigated factors potentially predictive of response to imatinib in a series of 40 patients with progressive AF included in a phase II trial of imatinib: we tested the presence of KIT exon 10 variant (M541L), the expression of imatinib-sensitive kinases and cell cycle proteins by immunohistochemistry (IHC), and other clinical and biological factors., Results: Of 10 patients for whom DNA could be extracted, 3 had a KIT exon 10 variant (30%), with no correlation with response or progression-free survival (PFS). The expression of other imatinib targets (PDGFRA/B, macrophage colony-stimulating factor receptor (M-CSFR)) and of downstream components of the cell cycle, cell proliferation and proliferation pathway (cyclin D1, ERK, MEK 1-2) did not correlate with PFS. Pre-treatment lymphopenia (<1500/microl) and tumour size >120 mm correlated with shorter PFS in univariate and multivariate analyses., Conclusion: Our findings show that a baseline biological characteristic of the patient is the major parameter influencing response to imatinib in aggressive fibromatosis. Tumour characteristics, including the presence of a KIT exon 10 M541L variant, may influence tumour control but this needs to be confirmed and better explained.

Unlabelled: Seroma is the most frequent minor complication after harvesting latissimus dorsi flap for breast reconstruction. It induces patient's discomfort and multiple consultations for punctions. The dead space resulting from the harvest has to be closed by the "quilting suture" in order to prevent the seroma. Our aim is to evaluate the efficiency and the tolerance of the quilting suture by comparing two groups of 100 patients who had a breast reconstruction by the same technic of extended latissimus dorsi flap, performed by the same surgeon, from 2004 to 2007. Half of patients had the classic way of dorsal closure, and the other half of patients had the dorsal quilting suture., Patients and Methods: In order to compare the two groups we have collected data concerning age, body mass index (BMI), tobacco use, postoperative complications, number and volume of punctions, draining time and postoperative pain. The efficiency of the quilting suture lies on a rigorous repartition of at least six sutures on the upper skin flap, 12 on the lower skin flap and under the skin suture line. The suture model is based on the one used for the Chippendale-designed sofa. We suture the skin flap while pushing down the shoulder, in order to split the skin tension and avoid traction on the final skin suture line. The procedure takes 15 minutes., Results: The "Chippendale" technic allows to reduce draining time from 12 days to 6 days. The incidence of chronic seroma is reduced by 50%. The dorsal wound healing seems also better thanks to tension reduction resulting from the quilting suture., Conclusion: The "Chippendale" technic is a quick, cheap and easy learned procedure, efficient for preventing chronic seroma after the latissimus dorsi flap. The postoperative recovery is eased and the patients comforted., (Copyright 2009 Elsevier Masson SAS. All rights reserved.)

Background: This prospective multicentric phase II study aimed to confirm the results of the C5R protocol of high-dose methotrexate (MTX)-based chemotherapy (CT) for immunocompetent primary central nervous system lymphoma., Patients and Methods: A total of 99 patients received age-adapted CT (C5R protocol) followed by radiotherapy. Patients younger than 61 years (group 1, n = 45) received the full C5R with MTX, doxorubicin, vincristine, cyclophosphamide, and cytarabine. Patients aged 61-70 years (group 2, n = 36) received reduced doses. Patients older than 70 years (group 3, n = 18) received four courses of MTX, cyclophosphamide, and etoposide., Results: Median age was 63 years and 51% of patients had performance status of more than one. Seventeen patients died of toxicity during CT. Complete response was achieved in 56%, 53%, and 28% of patients in groups 1, 2, and 3, respectively. With a median follow-up of 83 months, the 5-year progression-free survival was 31%, 28%, and 11% and the 5-year overall survival 42%, 31%, and 17% for groups 1, 2, and 3, respectively. Leukoencephalopathy occurred in 32% of assessable patients, in both group 1 and groups 2-3., Conclusion: The C5R protocol was feasible in the multicentric setting with favorable long-term survival in patients younger than 60 years. Despite dose adaptation, results in older patients were disappointing.

The decision-making bodies of the University Claude Bernard Lyon 1 (UCBL) established a Health Observatory - OSPEL (Observatory of Health Personnel, University of Lyon 1) whose mission is to report epidemiological results on the health of university staff. An initial study had the following objectives: 1 / identify and collect the health issues and themes that staff wanted to see addressed by OSPEL and 2 / test the survey methodology through self-administered questionnaire via Internet from a representative sample of UCBL staff. In December 2008, a sample of 15% of the professional population of the university (n = 694) was invited by e-mail to answer a self-administered questionnaire available on the Internet. A sample of 607 people received this e-mail and 242 staff responded (39.9% rate of participation). A weight was factored in and applied to responses to redress the sample base of respondents and render it representative of the professional population at UCBL. Respondents chose three priority themes, "Quality of Life - Overall Health ? Well-being, "Mental Health-Stress" and "Occupational Risks" as the primary topics to be addressed by OSPEL. Respondents were predominantly women (63.5%), administrative and technical staff (56.8%), as well as professors (77.3%). The interest of this study is centered on the reactivity and the ubiquity of the Internet / Intranet methodology which facilitated the targeted collection of the health expectations of university staff. This survey is a first step in the development of more focused epidemiological investigations in line with the expectations of UCBL staff. Future surveys should consider the physical and temporal constraints suggested in this study.

Lymphopenia is frequent in advanced cancers and predicts the toxicity of chemotherapy. Its effect on relapse and survival is uncertain. Its prognostic value for survival was analyzed in three databases of previously reported prospective multicenter studies: (a) FEC chemotherapy in metastatic breast carcinoma; (b) CYVADIC in advanced soft tissue sarcoma (European Organization for Research and Treatment of Cancer-Soft Tissue and Bone Sarcoma Group 62791); and (c) prospective, consecutive phase III studies of aggressive diffuse large-cell non-Hodgkin's lymphomas conducted at Centre Léon Bérard between 1987 and 1993. Univariate and multivariate analyses of prognostic factors for survival were performed. The incidence of lymphopenia of <1,000/microL before treatment was constant among the series: 25%, 24%, and 27%, respectively. Lymphopenia was significantly more frequent (P < 0.05) in metastatic breast cancer patients with performance status (PS) of >1, non-Hodgkin's lymphoma patients with international prognostic index (IPI) of > 0, and advanced soft tissue sarcoma and metastatic breast cancer patients with bone metastases. Inunivariate analysis, lymphopenia of <1,000/microL significantly correlated to overall survival in patients with metastatic breast cancer (median, 10 versus 14 mo; P < 0.0001), advanced soft tissue sarcoma (median, 5 versus 10 months; P < 0.01), and non-Hodgkin lymphoma (median, 11 versus 94 months; P < 0.0001). In multivariate analysis (Cox model), lymphopenia was an independent prognostic factor for overall survival in metastatic breast cancer [RR (relative risk), 1.8; 95% CI (confidence interval), 1.3-2.4] along with liver metastases and PS; in advanced soft tissue sarcoma (RR, 1.46; 95% CI, 1.0-2.1) along with liver metastases, lung metastases, and PS; and in non-Hodgkin's lymphoma (RR, 1.48; 95% CI, 1.03-2.1) along with IPI. Our findings show that lymphopenia is an independent prognostic factor for overall and progression-free survival in several cancers.

Purpose: Metastatic renal cancer patients with a single metastatic site are potentially amenable to interleukin 2 (IL-2) + IFN-alpha. A French immunotherapy intergroup multicenter trial assessed the potential benefit of i.v. over s.c. administration of IL-2 in this combination., Experimental Design: Untreated patients with one metastatic site were randomized to continuous i.v. infusion (18 x 10(6) IU/m(2)/d; arm A) or twice daily s.c. injections (9 x 10(6) or 18 x 10(6) IU; arm B) of IL-2, associated with s.c. IFN-alpha (6 x 10(6) IU) 3 days per week in both arms. Tumor response was assessed (WHO criteria) at weeks 12 and 24 to 26. The primary end point was overall survival, with an expected 15% improvement at 4 years with i.v. IL-2. The planned sample size was 220 (80% power, 5% significance, one-sided test). Intent-to-treat analysis was done and survivals were compared using log-rank tests., Results: From January 2000 to January 2005, 80 and 75 patients were randomized to arms A and B, respectively. Enrollment was stopped early because of low accrual; analysis was done at 42.5 months median follow-up. Patient characteristics were well balanced between groups. Response rates were 17.9% versus 21.3% in arms A and B. Progression-free survival rates were not significantly different. Overall survival difference was not significant: median 33 months (95% confidence interval, 27.0-40.2; P = 0.202)., Conclusions: In combination with IFN-alpha in selected, good prognosis metastatic renal cell carcinoma patients, i.v. IL-2 offers no significant advantage over s.c. IL-2 and induces higher toxicity. Although i.v. IL-2 induced longer responses, it seems unreasonable to continue recommending this regimen after the recent introduction of more effective therapies.
