Dose Escalation of Hypofractionated Radiation Therapy in Patients With Metastatic Cancer
A Study of Dose Escalation of Hypofractionated Radiation Therapy in Patients With Metastatic Cancer
Patients with metastatic cancer are generally treated with chemotherapy, which has improved median survival compared to best supportive care. Despite this, patients continue to have persistent disease at sites that were initially involved with cancer. Radiation therapy is an effective modality for treating localized cancer but generally has been only used for palliation of symptoms once a patient develops metastatic disease. Since patients often have persistent disease after chemotherapy, the goal of this trial is to use increasing doses of radiation therapy to all sites of involved disease in order to determine the safety and efficacy of hypofractionated radiation therapy.
The purpose of this study is to establish a maximum tolerated dose, dose-limiting toxicities, and recommended phase 2 dose of hypofractionated radiation therapy.

- Patients with AJCC (6th edition, 2002) stage IV cancer with distant metastases and without pleural or pericardial effusion at diagnosis and before start of study
- Patients with 1-5 sites of maximum tumor dimension (for each individual site) of ≤ 10 cm or < 500 cc volume and amenable to radiation therapy as seen on standard imaging
- Unidimensionally measurable disease (based on RECIST) is desirable but not strictly required
- Brain metastases must have been treated prior to enrollment on study, preferably with stereotactic radiosurgery
