Review Practice Guideline
[Indication of autologous stem cell transplantation in chronic inflammatory demyelinating polyneuropathy: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)].
Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a chronic autoimmune disease involving the peripheral nervous system, characterized by focal and segmental demyelination accounting for neurological deficit. CIDP diagnosis is based on several criteria and requires the presence of specific clinical symptoms and of demyelinating criteria on the electroneuromyogram (ENMG) or of additional supportive criteria (spinal fluid examination with dissociation between albumin level and cellular abnormalities, nervous abnormalities on MRI or other minor abnormalities on ENMG, demyelinating features on nerve biopsy or patient improvement under so-called first-line therapy with immunodulator treatment). ⋯ The efficacy of autologous hematopoietic cell transplantation (AHCT) has been shown in CIDP patients. The aim of these recommendations established by a working group of experts from the "Société française de greffe de moelle osseuse et thérapie cellulaire (SFGM-TC)", the group "maladies auto-immunes et thérapie cellulaire (MATHEC)" and the "filière de santé maladies rares neuromusculaire (FILNEMUS)" is to specify the eligibility criteria for AHCT in CIPD patients, to describe the mobilization and the conditioning regimen for the AHCT procedure, as well as the patient standardized post-transplant follow-up and the management of neurological treatment throughout the all procedure.

Review
[Does the FLOT regimen a new standard of perioperative chemotherapy for localized gastric cancer?]
FLOT-4 study recently reports that in patients with gastric cancer, perioperative chemotherapy with 5-fluorouracile, leucovorin, oxaliplatin and docetaxel (FLOT regimen) increases survival over standard ECF/ECX regimen (epirubicine, cisplatine and 5-fluorouracile [or capecitabine]). Does this study, make FLOT a new standard of perioperative chemotherapy for localized gastric cancer? Seven hundred and sixteen patients were included into that randomized study. Thirty seven per cent and 46% of the patients received the full planned treatment in the ECF/ECX group and in the FLOT group, respectively. ⋯ Overall, the number of patients with related serious adverse events (including those that occurred during hospital stay for surgery) was similar in the two groups, as was the number of toxic deaths and postoperative deaths. FLOT should be regarded as the recommended perioperative chemotherapy for patients with gastric cancer or adenocarcinoma of the gastro-esophageal junction. However, some doubts remain as regards of its use in the daily practice for unselected patients.

The adjuvant treatment of biliary tract cancers has long been poorly defined. In recent years, randomized trial data have been used to define treatment references. ⋯ Although the results in intention to treat were borderline significant on the primary endpoint, overall survival (P=0.097), sensitivity analyzes adjusted for prognostic factors and relapse-free survival analyses are clearly positive. The absolute benefit of +5%/+10% overall survival, combined with low and known toxicity profile, leads to recommending treatment for any cancer of the resected bile ducts (with the exception of gallbladder cancer pT1N0).

Allogeneic hematopoïetic stem cell transplantation is one of the most efficient curative treatment for acute leukemia. But it is also a heavy process with an important risk of complications, particularly infection and graft versus host disease. ⋯ To limit this microbiota impairment, we could restore a healthy microbiota by a fecal microbiota transplantation, which has already shown its efficiency in the treatment of Clostridium difficile infection. The aim of this review is to describe the intestinal microbiota, the link between microbiota and complications of allogeneic stem cells transplantation, and the recent published data on fecal microbiota transplantation in this field.

In this brief note, we review the state of knowledge about biomarkers that influence the response to current immunotherapies and the impact of recent technological developments (single-cell analysis, multi-dimensional imaging) on the analysis of these biomarkers. Also, new developments and strategies around CAR-T cells and bispecific antibodies in immuno-oncology are presented.
