Multicentric Evaluation of COVID-19 Impact on Cancer Patients' Diagnostic and Management: Set-up of Indicators

Study Overview
=================
Brief Summary
-----------------
The COVID-19 pandemic has deeply and globally impacted usual procedures and patients management in cancer centers. The aim of this study is to set-up and collect indicators to follow-up the activities of different cancer pathologies before and during the pandemic. Patients loss' of chance will be analysed in term of diagnosis and access to care (surgery, antineoplastic treatments). Data collection will focus on the analysis of 2 specific pathologies for French patients in the Auvergne-Rhône Alpes Area: peritoneal carcinosis and hepatocellular carcinoma.
