Given the extreme importance of the current pandemic caused by COVID-19 and due to the fact that scientists agree that there is no identified treatment, this paper analyzes in detail the treatment of a severe COVID-19 patient with convalescent plasma and drugs based on current guidelines for COVID-19 diagnosis and treatment. This can provide a reference for other medical institutions on rational drug use and pharmaceutical care for severe COVID-19 patients.

This document is a summary of the French intergroup guidelines regarding the management of metastatic colorectal cancer (mCRC) published in January 2019, and available on the French Society of Gastroenterology website (SNFGE) (www.tncd.org).
This collaborative work was realized by all French medical and surgical societies involved in the management of mCRC. Recommendations are graded in three categories (A, B and C), according to the level of evidence found in the literature, up until December 2018.
The management of metastatic colorectal cancer has become complex because of increasing available medical, radiological and surgical treatments alone or in combination. The therapeutic strategy should be defined before the first-line treatment, mostly depending on the presentation of the disease (resectability of the metastases, symptomatic and/or threatening disease), of the patient\'s condition (ECOG PS, comorbidities), and tumor biology (RAS, BRAF, MSI). The sequence of targeted therapies also seems to have an impact on the outcome (angiogenesis inhibition beyond progression). Surgical resection of metastases was the only curative intent treatment to date, joined recently by percutaneous tumor ablation tools (radiofrequency, microwave). Localized therapies such as hepatic intra-arterial infusion, radioembolization and hyperthermic intraperitoneal chemotherapy, also have seen their indications specified (liver-dominant disease and resectable peritoneal carcinomatosis). New treatments have been developed in heavily pretreated patients, increasing overall survival and preserving quality of life (regorafenib and trifluridine/tipiracil). Finally, immune checkpoint inhibitors have demonstrated high efficacy in MSI mCRC.
French guidelines for mCRC management are put together to help offer the best personalized therapeutic strategy in daily clinical practice, as the mCRC therapeutic landscape is complexifying. These recommendations are permanently being reviewed and updated. Each individual case must be discussed within a multidisciplinary team (MDT).

BACKGROUND: Recent guidelines have been published by a consensus of international experts (2016 ENETS (European NeuroEndocrine Tumor Society) guidelines). Nevertheless, in case of pancreatic neuroendocrine neoplasms (panNEN) the ENETS guidelines fail to propose a unique strategy in some situations, due to the lack of high-level of evidence and the absence of formal agreement between the experts drawing up the guidelines.
METHODS: A survey of 25 questions on panNEN was sent to 104 French experts challenging the guidelines. Questions focused on clinical situations in localized G-1/2 panNEN, localized G-3 panNEN, metastatic G-1/2 panNEN, and metastatic G-3 panNEN for which multiple options were proposed by the ENETS guidelines.
RESULTS: Fifty-seven experts (55%) have answered the survey. 18/25 questions obtained at least 50% similar responses, allowing a \"consensus\" or a \"position statement\". Among the results, surgery of small panNEN is preferred to surveillance in young patients; the temozolomide-capecitabine combination is favored instead of streptozotocin-based chemotherapy for G-1/2 metastatic panNEN.
CONCLUSIONS: French experts are mostly in line with the European guidelines, but some differences do exist. Whilst waiting for prospective studies, this survey helps physicians to propose standardized procedures and identifies situations where a step forward has been enabled by French experts. This questionnaire paves the way for a simplified therapeutic algorithm of panNEN.
