Collecting blood samples from cancer patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to collect blood samples from patients with various types of cancer, including prostate, breast, colon, lung, and liver cancer, to analyze immune suppressor cells before and after chemotherapy. Participants, aged 18 and older, will have approximately 50 ml of blood drawn, with additional samples taken during treatment if applicable. The study focuses on understanding the immune response and potential biomarkers related to cancer treatment outcomes, utilizing advanced genetic and molecular profiling techniques.
