Collection of Blood From Patients With Cancer - Full Text View

Sponsor:	National Cancer Institute (NCI)
Information provided by:	National Institutes of Health Clinical Center (CC)
ClinicalTrials.gov Identifier:	NCT00034216

Purpose

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.

Study Start Date:	April 2002
Estimated Primary Completion Date:	March 2005 (Final data collection date for primary outcome measure)

Detailed Description:

Patients with a prior diagnosis of malignancy or refractory cancer will be evaluated in the Medical Oncology Clinic, NCI. Blood samples may be collected at the initial visit and at follow-up visits. Blood samples will be processed and stored in the Laboratory of Tumor Immunology and Biology or Frederick for use in research efforts.
