Genetic Predictors of Efficiency and Safety of ICIs in Patients With Different Malignancies (ICIPRESIST-0519)

Study Overview
=================
Brief Summary
-----------------
This is a multicenter, non-interventional, retrospective study (with two prospective cohorts), including previously treated patients with melanoma, squamous cell lung cancer in the late stages (inoperable or metastatic) and Hodgkin disease at any stages. The duration of the follow-up will be 12-60 months. Data from medical records will be retrospectively collected at different points in time. The first data extraction will consist of collecting data from the initial level (before treatment with immune checkpoints inhibitors (anti-PD1 / PDl1) before the end of the recruitment period for this study (up to 3 years of follow-up). Two additional annual data collections are planned for display additional follow-up and data for patients who will survive.

The report will include a median of C with corresponding bilateral values of 95% CI. The proportion of patients who survive at certain points in time (1, 2, and 3 years), as well as the corresponding bilateral values of 95% CI, will be evaluated and reported. | dec 2021 |
