Hemolytic uremic syndrome following the infusion of oxaliplatin: case report

BACKGROUND: Oxaliplatin is a platinum derivative, which is used in the treatment of colorectal cancer. A small number of oxaliplatin-related hemolytic and/or thrombocytopenic reactions have been reported. We present a case of hemolytic-uremic syndrome that developed during the 4(th )cycle of combination chemotherapy with oxaliplatin, 5-fluorouracil and leucovorin. CASE PRESENTATION: A 52-year-old-male was administered chemotherapy with oxaliplatin, 5-fluorouracil and leucovorin for a Duke's stage C colorectal carcinoma. Three cycles of chemotherapy had been administered without complications when, at the beginning of the fourth cycle, the patient developed clinical and laboratory abnormalities consistent with the development of the hemolytic-uremic syndrome. Treatment was discontinued; the patient was managed with monitored IV hydration and loop diuretics, high dose corticosteroids and fresh frozen plasma infusions and recovered completely. CONCLUSION: The hemolytic-uremic syndrome may be a rare complication of oxaliplatin-based chemotherapy. Clinicians need to maintain a high index of suspicion to diagnose and treat this life-threatening adverse event

Massive ileal haemorrhage in Crohn's disease. Per-endoscopic clip treatment

Nous rapportons une observation de maladie de Crohn traitée par colectomie totale. Sept semaines après l'intervention, survenait une hémorragie iléale massive traitée avec succès par la pose endoscopique de clips. Un tel traitement endoscopique d'hémorragies massives compliquant une maladie de Crohn peut éviter un traitement chirurgical chez certains patients

Primary follicular lymphoma of the duodenum

La localisation duodénale des lymphomes folliculaires est considérée comme rare, mais l'incidence de ces tumeurs est en augmentation. Nous rapportons une observation de lymphome primitif du duodénum, montrant la similitude des données endoscopiqucs avec celles de la papulose lymphomateuse des lymphomes du manteau. Les techniques immunohistochimiques et cytogénétiques aident à différencier ces deux tumeurs. Il est essentiel de les différencier car leur pronostic et les modalités de traitement sont différents

Neoadjuvant Nivolumab Plus Ipilimumab and Adjuvant Nivolumab in Localized Deficient Mismatch Repair/Microsatellite Instability-High Gastric or Esophagogastric Junction Adenocarcinoma: The GERCOR NEONIPIGA Phase II Study

International audiencePURPOSEIn patients with resectable gastric/gastroesophageal junction (GEJ) adenocarcinoma, surgery plus perioperative platinum-based chemotherapy is the standard of care. Perioperative chemotherapy remains debatable for gastric/GEJ adenocarcinoma with deficient mismatch repair (dMMR)/microsatellite instability-high (MSI-H).PATIENTS AND METHODSNEONIPIGA (ClinicalTrials.gov identifier: NCT04006262) phase II study evaluated neoadjuvant nivolumab 240 mg once every two weeks ×6 and ipilimumab 1 mg/kg once every six weeks ×2, followed by surgery and adjuvant nivolumab 480 mg once every four weeks (nine injections) in patients with locally advanced resectable dMMR/MSI-H, clinical (c) tumor (T)2-T4 node (N)x metastasis (M)0 gastric/GEJ adenocarcinoma. The primary end point was a pathological complete response (pCR) rate.RESULTSBetween October 2019 and June 2021, 32 patients with dMMR/MSI-H gastric/GEJ adenocarcinoma were enrolled. The median age was 65.5 years (range, 40-80). Clinical stages were cT2-T3N0 (n = 9), cT2-T3N1 (n = 22), and cT3N1M1 (n = 1, wrongly included). With a median follow-up of 14.9 months (95% CI, 10.6 to 17.6), 32 patients received neoadjuvant immunotherapy (27 patients completed all cycles). Neoadjuvant therapy-related grade 3/4 adverse events occurred in six patients (19%). Twenty-nine patients underwent surgery; three did not have surgery and had complete endoscopic response with tumor-free biopsies and a normal computed tomography scan (two refused surgery and one had metastasis at inclusion). The rate of surgical morbidity (Clavien-Dindo classification) was 55% (one postoperative death occurred). All 29 patients had an R0 resection, and 17 (58.6%; 90% CI, 41.8 to 74.1) had pCR (pathological T0N0). Becker tumor regression grades 1a, 1b, 2, and 3 were observed in 17 patients, three (including two pathological T0N1), two, and seven patients, respectively. Of the 29 patients with surgery, 23 received adjuvant nivolumab. At database lock, no patient had relapse and one died without relapse.CONCLUSIONNivolumab and ipilimumab-based neoadjuvant therapy is feasible and associated with no unexpected toxicity and a high pCR rate in patients with dMMR/MSI-H resectable gastric/GEJ adenocarcinoma. © American Society of Clinical Oncology

394P Preliminary tolerance analysis of adjuvant chemotherapy in older patients after resection of stage III colon adenocarcinoma from PRODIGE 34-FFCD 1402-ADAGE randomized phase III trial

Background Colon adenocarcinoma occurs mainly in older patients (pts). Oxaliplatin based adjuvant chemotherapy has demonstrated an improvement on disease-free survival (DFS) after a stage III colon cancer resection in young pts. Nevertheless, the benefit of adjuvant chemotherapy is matter of debate in old pts. Methods The purpose of ADAGE trial is to compare the DFS obtain with oxaliplatin combined with fluoropyrimidine (F) to F alone in fit pts over 70 years (group 1) and F to observation in frail pts (group 2) after resection of a stage III colon cancer. We here report a preliminary tolerance analysis on 50% of the first pts enrolled in the study. Results The analysis was performed on 491 pts (378 in group 1 and 113 in group 2). Main pts characteristics were respectively for the group 1 and 2: male in 57% and 50%, median age of 76 and 83 years, ECOG=0 in 59% and 29%, abnormal IADL in 23% and 62%, no caregiver in 26% and 28%, fall ≤6 months in 9% and 14%, depression possible 28% and 40%, fail of one-leg balance in 20% and 59%, impaired cognition in 21% and 38%, G8 score <14 75% and 94%, undernutrition 35% and 48%. The toxicity was reported in the 434 pts treated excluding the 57 pts in observation arm of group 2. One treatment related death was reported in the doublet chemotherapy arm of group 1
