Purpose: Multiple studies have demonstrated that electronic patient-reported outcomes (ePROs) improve overall survival and quality of life in cancer care. However, there are no specific prospective data on remote ePRO monitoring in the older population, although they represent a significant proportion of patients with cancer.

Patients And Methods: From February 2021 to April 2022, patients age 75 years and older under active anticancer treatment were consecutively recruited in six institutions.

Unlabelled: Advanced age in patients with colorectal cancer is a factor of poor prognosis, but little is known about geriatric factors associated with survival and chemotherapy prescription in frail elderly patients. Our research sought to investigate these factors in older patients with metastatic colorectal cancer (mCRC).

Patients And Methods: patients aged ≥75 years, who were treated for mCRC and have had a Comprehensive Geriatric Assessment (CGA) due to their frailty, were included in this multicenter practice study in the Loire Valley region (France).

The growing incidence of cancer associated with an aging population implies important health challenges that require questioning on the care management of older adults with cancer. There is a need to rethink the care management of older cancer patients with patient-centered decisions and an adjustment of the care pathway for this population. The Priorities Age Cancer (PAC) French group, made up of physicians, pharmacists and researchers in geriatric oncology, set up proposals to answer this need.

Background & Aims: Medico-economic data of patients suffering from chronic nausea and vomiting are lacking. In these patients, gastric electrical stimulation (GES) is an effective, but costly treatment. The aim of this study was to assess the efficacy, safety and medico-economic impact of Enterra therapy in patients with chronic medically refractory nausea and vomiting.

Background & Aims: There have been conflicting results from trials of gastric electrical stimulation (GES) for treatment of refractory vomiting, associated or not with gastroparesis. We performed a large, multicenter, randomized, double-blind trial with crossover to study the efficacy of GES in patients with refractory vomiting, with or without gastroparesis.

Methods: For 4 months, we assessed symptoms in 172 patients (66% women; mean age ± standard deviation, 45 ± 12 years; 133 with gastroparesis) with chronic (>12 months) of refractory vomiting (idiopathic, associated with a type 1 or 2 diabetes, or postsurgical).

Background: Studies have shown the negative prognostic impact of increased time between colectomy and postoperative adjuvant chemotherapy (AC) in colon cancer (CC). Our aim was to investigate the role of age and non-organizational factors on access and time to AC.

Methods: All adult patients undergoing surgery for stage II or III CC in the "Région Centre-Val de Loire" in 2013, were selected.

Background: Doxorubicin Transdrug (DT), a nanoformulation of doxorubicin, was demonstrated to overcome the chemoresistance of hepatocellular carcinoma (HCC) in preclinical models. Its efficacy and safety were thus investigated in phase I and randomised phase II trials in unresectable HCC.

Patients And Methods: Phase I was a single dose of DT through the hepatic intra-arterial (HIA) route, dose-escalating 3+3 trial, evaluating five-dose levels from 10 to 40 mg/m with maximal tolerated dose (MTD) as primary endpoint.

Purpose: Self-expandable metallic stent (SEMS) placement is an accepted palliative therapy for management of acute malignant bowel obstruction in advanced colorectal cancer. Nevertheless, data are lacking on the effects of systemic chemotherapy combined with colorectal SEMS. The aim of this study was to investigate the safety and efficacy of palliative chemotherapy for advanced colorectal cancer combined with colorectal SEMS placement.

Importance: Aside from the multikinase inhibitor sorafenib, there are no effective systemic therapies for the treatment of advanced hepatocellular carcinoma.

Objective: To assess the efficacy of everolimus in patients with advanced hepatocellular carcinoma for whom sorafenib treatment failed.

Design, Setting, And Participants: EVOLVE-1 was a randomized, double-blind, phase 3 study conducted among 546 adults with Barcelona Clinic Liver Cancer stage B or C hepatocellular carcinoma and Child-Pugh A liver function whose disease progressed during or after sorafenib or who were intolerant of sorafenib.

Background: Immunochemical faecal occult blood tests have greater sensitivity for colorectal cancer screening than guaiac-based tests; however the number of positive tests required is still under discussion.

Methods: A direct comparison of Hemoccult II with two immunochemical quantitative tests (OC-Sensor and FOB-Gold) using a 2-sample strategy was performed in over 30,000 patients undergoing colorectal cancer screening in France.

Results: Positivity ratio between immunochemical tests and Hemoccult II varied between 2.

Context: The setting of multidisciplinary meeting (MDM) by the French Cancer Plan has introduced new decisional elements in the patient-physician relationship in oncology.

Methods: To assess the potential impact of MDM on this relationship, a study was conducted at the Tours Hospital: 145 questionnaires were collected from patients whose files have been discussed in MDM, 40 questionnaires were collected from physicians attending these meetings and an analysis of 324 files was performed.

Results: Patients recognize the decisional process of MDM as reassuring for 80% of them.

Background: Physicians may be unaware of the severity and extent of gastroesophageal reflux disease (GERD) in their patients. The aim of this study was to evaluate patient-physician agreement concerning proton pump inhibitor (PPI) treatment.

Methods: 1818 French primary-care physicians and 5174 adult patients with GERD who were taking PPIs answered questions regarding symptoms and treatment satisfaction.

Introduction: Bevacizumab is an antivascular endothelial growth factor humanized monoclonal antibody used to inhibit angiogenesis in cancer. It displays an important interindividual pharmacokinetic variability, which could explain part of the interindividual differences in clinical response. Therefore, an assay to measure bevacizumab serum concentrations is needed.

Cetuximab is an anti-epidermal growth factor receptor monoclonal antibody used in the treatment of colorectal and head and neck cancers. Part of the interindividual differences in response may be explained by interindividual variability in pharmacokinetics. An assay measuring cetuximab serum concentrations is therefore needed.

Purpose: A phase III, multicenter, randomized study compared conventional dosing of fluorouracil (FU) plus folinic acid with pharmacokinetically guided FU dose adjustment in terms of response, tolerability, and survival.

Patients And Methods: Two hundred eight patients with measurable metastatic colorectal cancer were randomly assigned to one of two arms: arm A (104 patients; 96 assessable), in which the FU dose was calculated based on body-surface area; and arm B (104 patients; 90 assessable), in which the FU dose was individually determined using pharmacokinetically guided adjustments. The initial regimen was 1,500 mg/m(2) FU plus 200 mg/m(2) folinic acid infusion during a continuous 8-hour period administered once weekly.

Background And Aim: Dietary polyethylene glycol (PEG) is extraordinarily potent in the chemoprevention of experimental colon carcinogenesis. PEG is used to treat constipation in France and in the USA. French laxatives include Forlax (PEG4000), Movicol and Transipeg (PEG3350), and Idrocol (pluronic F68).

Objective: The aim of our study was to evaluate the feasibility of enteral jejunal nutrition for acute pancreatitis using a self-propelling spiral distal end jejunal tube.

Methods: Sixteen consecutive patients with acute pancreatitis in whom Flocare tubes were placed for enteral nutrition were included in this open prospective study. All of them had pancreatic and/or peripancreatic necrosis (Balthazar >=D).

Background: Irritable bowel syndrome (IBS) is a common functional gastro-intestinal disease. In the absence of specific markers, definition and hence diagnosis depend on clinical presentation. Of the various attempts to set criteria for IBS, the most recent are Rome I and Rome II classifications.
