Summary

This study collects blood and other biospecimens from adults with cancer to analyze immune-suppressing cells and genetic changes. Up to 1,750 participants will provide samples before and after chemotherapy. The goal is to better understand how cancer affects the immune system, but no treatment is given as part of this research.
