简要总结
RATIONALE: Measuring levels of transforming growth factor-beta (TGF-beta) in the blood of patients with epithelial cancers (head and neck, lung, breast, colorectal, and prostate) may help doctors predict how patients will respond to treatment with radiation therapy.
PURPOSE: This research study is measuring levels of TGF-beta in patients with epithelial cancers who are undergoing radiation therapy.
详细描述
OBJECTIVES:
- To determine whether there is a dose-dependent increase in TGF-beta following radiotherapy in patients with epithelial cancers.
OUTLINE: Patients undergo blood sample collection prior to treatment, 24-72 hours after the first fraction of radiotherapy, and at the end of radiotherapy. Patients will also be asked for a weekly blood sample, but this is optional. Samples are analyzed to compare pre- and post-treatment TGF-beta levels.
