Impact of Trabectedin Interruption and Subsequent Rechallenge on Progression in Patients With Advanced Soft Tissue Sarcoma: Long-term Follow-up of the T-DIS trial.

Objective: To assess the impact of trabectedin rechallenge.

Patients And Methods: In the T-DIS trial (NCT0130309), after the 6 initial cycles of trabectedin, patients who were free from progressive disease (PD) were randomly assigned either to continuous treatment with trabectedin (C arm) or therapy interruption (I arm). Patients randomized in the interruption arm were allowed to restart trabectedin in case of PD.

The FREGAT biobank: a clinico-biological database dedicated to esophageal and gastric cancers.

Background: While the incidence of esophageal and gastric cancers is increasing, the prognosis of these cancers remains bleak. Endoscopy and surgery are the standard treatments for localized tumors, but multimodal treatments, associated chemotherapy, targeted therapies, immunotherapy, radiotherapy, and surgery are needed for the vast majority of patients who present with locally advanced or metastatic disease at diagnosis. Although survival has improved, most patients still present with advanced disease at diagnosis.

Safety and efficacy of regorafenib in patients with advanced soft tissue sarcoma (REGOSARC): a randomised, double-blind, placebo-controlled, phase 2 trial.

Background: Regorafenib is a multikinase inhibitor with proven activity in refractory gastrointestinal stromal tumours and chemotherapy-refractory advanced colorectal cancers. We assessed this agent's efficacy and safety in patients with metastatic soft tissue sarcomas previously treated with anthracycline.

Methods: In this randomised, double-blind, phase 2 trial undertaken in France and Austria, we enrolled patients aged 18 years and older with advanced soft tissue sarcomas who had received previous doxorubicin or other anthracycline treatment.

Circulating vascular endothelial growth factor (VEGF) as predictive factor of progression-free survival in patients with advanced chordoma receiving sorafenib: an analysis from a phase II trial of the french sarcoma group (GSF/GETO).

Background: Patients with advanced chordoma are often treated with tyrosine kinase inhibitors without any predictive factor to guide decision. We report herein an ancillary analysis of the the Angionext phase II trial (NCT 00874874).

Results: From May 2011 to January 2014, 26 were sampled.

Survival, safety, and prognostic factors for outcome with Regorafenib in patients with metastatic colorectal cancer refractory to standard therapies: results from a multicenter study (REBECCA) nested within a compassionate use program.

Background: Randomized trials have shown a survival benefit for regorafenib over placebo in patients with metastatic colorectal cancer (mCRC) that progressed after standard therapies. We evaluated survival and safety outcomes in patients treated with regorafenib in a real-life setting.

Methods: REBECCA is a cohort study nested within a compassionate use program designed to evaluate survival, safety, and potential prognostic factors for outcome associated with regorafenib in patients with mCRC refractory to standard therapies.

Preoperative chemoradiation with paclitaxel-carboplatin or with fluorouracil-oxaliplatin-folinic acid (FOLFOX) for resectable esophageal and junctional cancer: the PROTECT-1402, randomized phase 2 trial.

Background: Often curative treatment for locally advanced resectable esophageal or gastro-esophageal junctional cancer consists of concurrent neoadjuvant radiotherapy and chemotherapy followed by surgery. Currently, one of the most commonly used chemotherapy regimens in this setting is a combination of a fluoropyrimidin and of a platinum analogue. Due to the promising results of the recent CROSS trial, another regimen combining paclitaxel and carboplatin is also widely used by European and American centers.

HIGH-DOSE 131I-MIBG THERAPIES IN CHILDREN: FEASIBILITY, PATIENT DOSIMETRY AND RADIATION EXPOSURE TO WORKERS AND FAMILY CAREGIVERS.

The objective of the present multicentric phase II study (MIITOP) was to determine the response rate, survival and toxicity of tandem infusions of 131I-meta-iodobenzylguanidine (mIBG) and topotecan in children with relapsed/refractory neuroblastoma. High-dose 131I-mIBG therapy programme requires a deal of planning, availability of hospital resources and the commitment of individuals with training and expertise in multiple disciplines. Here in the present study, procedures and the results of patient's dosimetry, as well as family and worker's exposures, were reported for the patients treated in Lille.

First-Line Chemotherapy for Metastatic Esophageal Squamous Cell Carcinoma: Clinico-Biological Predictors of Disease Control.

Objective: This study aimed to identify predictors of tumor control (TC) in metastatic esophageal squamous cell carcinoma patients receiving first-line chemotherapy.

Methods: A development cohort of 68 patients from a prospective multicenter trial (NCT01248299) was used to identify predictors of TC at first radiological tumor assessment and to generate a predictive score for TC. That score was applied in an independent retrospective single-center validation cohort of 60 consecutive patients.

Selection of ultimately ill cancer patients able to fulfill a questionnaire: Identification of inherent biases.

Aim: Physical or psychological well-being is an essential component of quality care assessment in palliative unit. This assessment is mainly based on self-assessment (questionnaires or interviews). The aim of this study is to compare the clinical characteristics of patients able to fulfill a questionnaire and those not able to do that.

Paclitaxel Given Once Per Week With or Without Bevacizumab in Patients With Advanced Angiosarcoma: A Randomized Phase II Trial.

Purpose: The aim of this randomized, phase II trial was to explore the activity and safety of adding bevacizumab to paclitaxel once per week in treatment of angiosarcomas (AS).

Methods: Patients were treated with paclitaxel alone (90 mg/m(2) per week for six cycles of 28 days each; arm A) or with paclitaxel combined with bevacizumab (10 mg/kg once every 2 weeks; arm B). In the combination treatment arm, bevacizumab was administered after the six cycles of chemotherapy as maintenance therapy (15 mg/kg once every 3 weeks) until intolerance or progression occurred.

Improvement of the initial management of sarcomas after the dissemination of evidence-based guidelines depends on the primary sarcoma location: a population-based study.

Background: Improvement of the initial management of sarcomas after the dissemination of evidence-based guidelines depends on the primary sarcoma location: a population-based study. To improve the initial management of adult sarcomas, a regional expert team in Northern France performed two actions: dissemination of evidence-based guidelines (EBG) for the management of soft tissue/visceral sarcoma and yearly educational symposia. The aim of this study was to measure the impact of the dissemination of EBG on the key-indicators of adult sarcoma management.

Study protocol of REGOSARC trial: activity and safety of regorafenib in advanced soft tissue sarcoma: a multinational, randomized, placebo-controlled, phase II trial.

Background: Angiogenesis, among other signaling pathways, plays a key-role in sarcoma biology. Regorafenib (RE) has recently been shown to be effective in imatinib and sunitinib-refractory GIST in a phase III trial.

Methods/design: We are conducting an international trial (France, Austria and Germany) consisting in 4 parallel double-blind placebo-controlled randomized (1/1) phase II trials to assess the activity and safety of RE in doxorubicin-refractory STS (ClinicalTrials.

Interruption versus continuation of trabectedin in patients with soft-tissue sarcoma (T-DIS): a randomised phase 2 trial.

Background: The benefit or harm of trabectedin discontinuation in patients with non-progressive soft-tissue sarcoma remains unclear. We report the final analysis of a phase 2 trial investigating the clinical benefit of continuation of trabectedin treatment until progression versus interruption of therapy after six treatment cycles in patients with advanced soft-tissue sarcoma.

Methods: For this open-label, non-comparative, multicentre, phase 2 study, eligible adult patients with advanced soft-tissue sarcomas, who had previously received doxorubicin-based chemotherapy and were able to receive trabectedin, were enrolled from 14 centres of the French Sarcoma Group.

Comparison of response evaluation criteria in solid tumours and Choi criteria for response evaluation in patients with advanced soft tissue sarcoma treated with trabectedin: a retrospective analysis.

Background: To assess the additional value of density measurement using contrast-enhancement sequences (Choi assessment) in a real-life cohort of adult soft tissue sarcoma patients treated with trabectedin.

Methods: Eligibility criteria included adults (age ⩾18) treated between 01/2007 and 12/2011, with at least two trabectedin cycles after failure or intolerance to doxorubicin/ifosfamide. Baseline and first computed tomography (CT)-scans were centrally reviewed by an experienced radiologist.

Determinants of patient delay in doctor consultation in head and neck cancers (Protocol DEREDIA).

Introduction: Reducing the time between the onset of the first symptoms of cancer and the first consultation with a doctor (patient delay) is essential to improve the vital prognosis and quality of life of patients. Longer patient delay is linked to the already known sociodemographic, socioeconomic, socioeducational, sociocultural and socioprofessional factors. However, recent data suggest that some sociocognitive and emotional determinants may explain patient delay from a complementary point of view.

Low level of baseline circulating VEGF-A is associated with better outcome in patients with vascular sarcomas receiving sorafenib: an ancillary study from a phase II trial.

We have carried out a stratified phase II study of sorafenib (So) in patients with advanced angiosarcoma (n = 32) and epithelioid hemangioendothelioma (n = 13). This report concerns the correlative analysis of the predictive values of circulating pro/anti-angiogenetic biomarkers. Using the ELISA method (R&D Systems), circulating biomarkers (VEGF-A, in picograms per milliliter), thrombospondin-1 (TSP1, in micrograms per milliliter), stem cell factor (SCF, in picograms per milliliter), placental growth factor (PlGF, in picograms per milliliter), VEGF-C (in picograms per milliliter), and E-selectin (in nanograms per milliliter) were measured before So treatment and after 7 days.

Clinical complete responders to definite chemoradiation or radiation therapy for oesophageal cancer: predictors of outcome.

Background: To identify predictors of long-term outcome for patients with clinical complete response (cCR) after definite chemoradiotherapy (CRT) or radiation therapy (RT) for oesophageal cancer (EC).

Methods: In this retrospective study, we reviewed the files of all patients from our institution that underwent definitive RCT or RT for EC, from January 1998 to December 2003. Among 402 consecutive patients with EC, 110 cCR responses were observed, i.

Sorafenib in patients with progressive epithelioid hemangioendothelioma: a phase 2 study by the French Sarcoma Group (GSF/GETO).

Background: There is no standard treatment for progressive epithelioid hemangioendothelioma (EHE). To investigate the significant vascularization of EHE, the activity/toxicity of sorafenib in patients with progressive EHE was explored.

Methods: In this multicenter, 1-stage, phase 2 trial of sorafenib (800 mg daily), the primary endpoint, which was chosen by default, was the 9-month progression-free rate.

Predictive value of clinical judgment of tumour progression in phase II trials.

Background: The diagnosis of tumour progression or progressive disease (PD) is a key element for designing and interpreting contemporary phase II trials. In some cases, PD is stated by the physician and is not formally confirmed by imaging.

Purpose: In this study, we intend to analyze the value of the PD based on clinical judgment and the risk of overestimating the occurrence of PD by clinical judgment.

Serum creatine kinase increase in patients treated with tyrosine kinase inhibitors for solid tumors.

Regarding the frequency of muscular complains with the use of tyrosine kinase inhibitors (TKIs), we hypothesize that creatine kinase (CK) elevation may be more frequent than usually reported. We conducted a prospective study on patients treated with TKIs for solid tumors, to assess the incidence of CK increase on treatment. Most of the patients (105/155) had a gastrointestinal stromal tumor.

Sorafenib for patients with advanced angiosarcoma: a phase II Trial from the French Sarcoma Group (GSF/GETO).

Background: Angiosarcomas account for <2% of all soft tissue sarcomas. This subtype is one of the most aggressive forms of soft tissue sarcoma. The prognosis for angiosarcoma patients in the advanced phase remains poor with current cytotoxic agents (progression-free survival [PFS] time of ∼4 months and overall survival [OS] time of ∼8 months).

Predictors for establishing recommended phase 2 doses: analysis of 320 dose-seeking oncology phase 1 trials.

Introduction: For decades, determination of the recommended Phase 2 dose (RP2D) was based on the toxicity (especially the maximum tolerated dose or MTD) experienced by patients enrolled in dose-escalating Phase 1 trials investigating anti-cancer agents. Recent studies suggest that this toxicity-based strategy is not suitable for modern anti-cancer agents. We conducted a retrospective study to identify the risk factor(s) for failing to determine the RP2D according to the MTD.
