[Chemoradiation for oesophageal cancer: A critical review of the literature]. / Chimioradiothérapie des cancers de l'œsophage : revue critique de la littérature.

Locally advanced oesophageal cancer treatment requires a multidisciplinary approach with the combination of chemotherapy and radiotherapy for preoperative and definitive strategy. Preoperative chemoradiation improves the locoregional control and overall survival after surgery for locally advanced oesophageal cancer. Definitive chemoradiation can also be proposed for non-resectable tumours or medically inoperable patients. Besides, definitive chemoradiation is considered as an alternative option to surgery for locally advanced squamous cell carcinomas. Chemotherapy regimen associated to radiotherapy consists of a combination of platinum derived drugs (cisplatinum or oxaliplatin) and 5-fluorouracil or a weekly scheme combination of carboplatin and paclitaxel according to CROSS protocol in a neoadjuvant strategy. Radiation doses vary from 41.4Gy to 45Gy for a preoperative strategy or 50 to 50.4Gy for a definitive treatment. The high risk of lymphatic spread due to anatomical features could justify the use of an elective nodal irradiation when the estimated risk of microscopic involvement is higher than 15% to 20%. An appropriate delineation of the gross tumour volume requires an exhaustive and up-to-date evaluation of the disease. Intensity-modulated radiation therapy represents a promising approach to spare organs-at-risk. This critical review of the literature underlines the roles of radiotherapy for locally advanced oesophageal cancers and describes doses, volumes of treatment, technical aspects and dose constraints to organs-at-risk.

[From quality management to dynamic management through quality: Deployment within a radiotherapy group]. / De la démarche qualité vers la gestion dynamique par la qualité : déploiement au sein d'un groupe de radiothérapie.

In 2015, the quality group of the radiotherapy clinic Groupement de Radiothérapie et d'Oncologie des Pyrénées (GROP, Pau, France) decided to review the deployment of its quality approach in order to optimize it continuously. For this, two improvements were proposed: an involvement of process drivers and a material and financial investment in document management software. The implementation of these organizational and managerial provisions enabled us to better cover the requirements of the ISO 9001 standard, the international reference in quality management.

The management of adult aggressive non-Hodgkin's lymphomas.

Aggressive non-Hodgkin's lymphona include diffuse large B-cell lymphoma, anaplastic large cell lymphona, and different peripheral T-cell lymphomas. An international prognostic index has been developed including age, serum LDH, performance status, and extranodal involvement. For localized aggressive lymphoma, the preferred treatment is 3-4 CHOP and radiation therapy, with a cure rate of 70-80%. For disseminated aggressive lymphoma, current regimens have a cure rate of less than 40%. Innovative strategies, including dose escalation, autologus stem cell support, new drugs, and immunotherapy are being explored to improve these results.

A randomized study of bolus fluorouracil plus folinic acid versus 21-day fluorouracil infusion alone or in association with cyclophosphamide and mitomycin C in advanced colorectal carcinoma.

From May 1988 to June 1992, 129 eligible patients suffering from measurable advanced colorectal cancer were enrolled in a randomized study comparing bolus fluorouracil plus leucovorin (FU-FA); continuous fluorouracil infusion (FU-cont); FUcont plus cyclophosphamide and mitomycin C (FUMIC). FU-FA consisted of weekly fluorouracil (FUra) bolus (600 mg/m2) 1 hour after the initiation of a 2-hour infusion of 500 mg/m2 of leucovorin, for 6 weeks every 8 weeks. FUcont patients were planned to receive 400 mg/m2/day FUra infusion, for 21 days every 28 days. In FUMIC patients, FUcont was associated with weekly cyclophosphamide bolus (300 mg/m2) and monthly mitomycin C bolus (10 mg/m2). Quality of life was evaluated using six linear analogue scales, completed by the patient. Accrual in the FUMIC arm was stopped after the 25th patient because of toxicity. The response rates were 22 of 48 (45.8%) with FUcont and 13 of 52 (25%) with FU-FA (P = .048). Progression-free survival (median: 8 v 4.4 months; P = .0026) and overall survival (median: 12.9 v 9.6 months; P = .028) were significantly greater for the FUcont arm compared with the FU-FA arm. Toxicity was observed in 62% of the FUcont patients (grade 3-4: 10%), mainly hand-foot syndrome, diarrhea, mucositis, and mainly gastrointestinal in 69% of the FU-FA patients (grade 3-4: 11.6%). Linear analogue scales exploring quality of life, available for the first 6 months, gave similar scores in FU-FA and FUcont patients. We conclude that this FUcont schedule, achieving high FUra dose-intensity, offers significant advantages, in terms of response and survival, over weekly FUra plus leucovorin.
