About
This study will collect blood from patients with cancer to study the level of cells which decrease the immune response (suppressor cells) before and after chemotherapy. Patients 18 years of age and older with cancer may participate. This study does not involve treatment.
Participants will have about 50 ml (3 tablespoonfuls) of blood drawn. Depending on their condition, patients may be invited to enroll in a clinical research study involving chemotherapy, radiotherapy, or surgery. Additional 40-ml blood samples may be drawn during the course of treatment.
