Cryosurgery in Treating Patients With Soft Tissue Sarcoma

2014-08-27 03:58:58 | BioPortfolio


RATIONALE: Cryosurgery kills cancer cells by freezing them. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining cryosurgery with chemotherapy may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of cryosurgery with or without chemotherapy in treating patients who have soft tissue sarcoma.


OBJECTIVES: I. Assess the safety and morbidity associated with cryosurgical ablation in patients with soft tissue sarcomas of the extremity.

OUTLINE: All patients undergo 1 session of cryoablation. Patients with high-grade sarcoma receive systemic chemotherapy 10-14 days after cryoablation at the discretion of the consulting medical oncologist, and undergo surgery 2-3 weeks following chemotherapy. Patients with low-grade sarcoma and those with high-grade sarcoma who do not receive chemotherapy undergo surgery 4-6 weeks after cryoablation. Surgery for all patients consists of en bloc resection or amputation, with limb salvage attempted when feasible. Patients are followed weekly for 3 weeks.

PROJECTED ACCRUAL: A total of 12 patients (approximately 6 patients with low-grade, high-risk sarcoma and 6 with high-grade sarcoma) will be entered over approximately 6 months. The study will be suspended for the following: vascular complication that requires surgical intervention for correction in 2 patients; any neuropraxia that shows no evidence of resolution after 3 months in 2 patients; any wound complication that requires surgical correction in 4 patients; or any deep wound infection that requires surgical drainage in 4 patients.

Medical and Biotech [MESH] Definitions

A followup operation to examine the outcome of the previous surgery and other treatments, such as chemotherapy or radiation therapy.

Drug treatment designed to further diminish the disease toward complete remission following INDUCTION CHEMOTHERAPY. It helps to consolidate the gains during induction chemotherapy and may be followed by MAINTENANCE CHEMOTHERAPY.

Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.

Treatment designed to help prevent a relapse of a disease following the successful primary treatments (INDUCTION CHEMOTHERAPY and CONSOLIDATION CHEMOTHERAPY) with a long-term low-dose drug therapy.

Combined chemotherapy and radiotherapy given to augment some other form of treatment such as surgery. It is commonly used in the therapy of cancer.
