Pegaspargase (Oncaspar®), a pegylated form of native Escherichia Coli-derived L-asparaginase is an essential component chemotherapy used in the treatment of acute lymphoblastic leukemia (ALL) in pediatric and adult patients. Its particular toxicity profile requires a specific management to improve safety and tolerability and optimize treatment outcome and therefore survival. Within the framework of workshops of practice harmonization of the French Society of Children and Adolescent Cancers, diagnostic and management of the most commonly occuring toxicities (excluding coagulation abnormalities) during Pegaspargase treatment were reviewed according to the analysis of published studies., (Copyright © 2022 Société Française du Cancer.

In France, determination of the mutation status of RAS genes for predictive response to anti-EGFR targeted treatments is carried out by public platforms of molecular biology of cancer created by the French National Cancer Institute. This study aims to demonstrate the feasibility of these analyses by a private pathology laboratory (MEDIPATH) as per the requirements of accreditation. We retrospectively studied the mutation status of KRAS and NRAS genes in 163 cases of colorectal metastatic cancer using the Cobas ® technique. We compared our results to those prospectively obtained through pyrosequencing and allelic discrimination by the genetic laboratory of solid tumors at the Nice University Hospital (PACA-EST regional platform). The results of both series were identical: 98.7% positive correlation; negative correlation of 93.1%; overall correlation of 95.7% (Kappa=0.92). This study demonstrates the feasibility of molecular analysis in a private pathology laboratory. As this practice requires a high level of guarantee, its accreditation, according to the NF-EN-ISO15189 quality compliance French standard, is essential. Conducting molecular analysis in this context avoids the steps of routing the sample and the result between the pathology laboratory and the platform, which reduces the overall time of rendering the result. In conclusion, the transfer of some analysis from these platforms to private pathology laboratories would allow the platforms to be discharged from a part of routine testing and therefore concentrate their efforts to the development of new analyses constantly required to access personalized medicine., (Copyright © 2017.

Primary neuroendocrine carcinoma arises mainly in the gastrointestinal tract, lungs and pancreas, localization in the fallopian tube is exceptional with only one case being reported in literature. This second case concerns a 54-year-old patient, diagnosed at the Pierre-Zobda-Quitman hospital. Tumor histology revealed a poorly differentiated carcinoma with medium to large cells, marked atypia and high mitotic activity. Immunostaining was positive for chromogranine A, synaptophysine and CD56. Primary fallopian tube neuroendocrine carcinoma requires cross referencing of the radiological, pathological and immunohistochemical findings and discarding the differential diagnoses., (Copyright (c) 2010 Elsevier Masson SAS.
