Radiosurgery in Treating Patients With Kidney Tumors
Evaluation of a Radio-Surgical Approach for the Treatment of Kidney Tumors in Poor Surgical Candidates
RATIONALE: Radiosurgery can send x-rays directly to the tumor and cause less damage to normal tissue.
PURPOSE: This phase I/II trial studies the side effects and best dose of giving stereotactic radiosurgery and to see how well it works in treating patients with kidney tumors who are poor candidates for surgery.
調査の概要
詳細な説明
OBJECTIVES:
Primary
- To evaluate and compare the clinical safety of utilizing four different schemes of radiosurgical ablative techniques for treating poor surgical candidates with renal tumors.
Secondary
- To evaluate and compare the clinical and radiographic efficacy of four different schemes of radiosurgical ablation of renal tumors in poor surgical candidates.
Serum Blood Marker Objective:
- To determine if serum markers collected before and after radiation may give a predictive indication of tumor response.
OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.
Patients undergo placement of 2-3 fiducial markers in or near the renal tumor. Patients then undergo 4 fractions of stereotactic radiosurgery in the absence of disease progression or unacceptable toxicity. Treatment may repeat at 6 months if tumor is still present.
After radio-surgery, follow-up will be done at 1 , 3 and 6 months and then every 6 months post radiosurgery for a total of 36 months.
PROJECTED ACCRUAL: A total of 32 patients will be accrued for this study.

実験的:Series 1: Stereotactic radiosurgery
Series I: Radiation will be delivered in 4 fractions.
The initial dose level will be 6 Gy per fraction to a total dose of 24 Gy in 4 fractions.
Doses will be escalated at 2 Gy per fraction increments to 12 Gy per fraction to a total dose of 48 Gy.
|
Series I: Radiation will be delivered in 4 fractions. Series II: Radiation will be delivered in 3 fractions.
At 6 months,an optional percutaneous renal biopsy will be obtained of the targeted tumor, under ultrasound (US) or CT guidance.
ELISA blood testing just prior to and immediately following each daily radiation therapy session.
Approximately 5cc of blood will be collected within 2 hours prior to and following completion of fractionated radiation therapy to assess the levels of MIF (both MIF-1 and MIF-2) and VEGF.
|
|
実験的:Series 2: Stereotactic radiosurgery
Series II: The initial dose level will be 48 Gy to the target volume (tumor) in 3 fractions of 16 Gy per fraction.
If acute toxicity is acceptable, then the next four patients will be escalated to 54 Gy in 3 fractions of 18 Gy.
Finally if a dose limit has not been reached, the last group of four patients will be treated to 60 Gy in 3 fractions of 20 Gy each.

Maximum Tolerated Dose of Radiosurgery
時間枠:once every 4 weeks
|
Dose escalation stops if 2/4 (50%) or 3/8 (37.5%) of participants experience DLTs in a given dose level cohort.
The maximum tolerated dose will be one dose level below which the DLTs were exceeded.
