  Purpose

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving sorafenib together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

PURPOSE: This phase I/II trial is studying the side effects and best dose of radiation therapy given together with sorafenib followed by surgery in treating patients with soft tissue sarcoma.

Detailed Description:

OBJECTIVES:

Primary

  • To determine the maximum tolerated dose of sorafenib tosylate when combined with conformal external beam radiotherapy prior to resection with curative intent in patients with soft tissue sarcoma of the extremity or body wall. (Phase I)
  • To determine the rate of near-complete (≥ 95% tumor necrosis) pathological response to this regimen in these patients. (Phase II)

Secondary

  • To describe the toxicities associated with this regimen.
  • To determine the rate of R0 (negative resection margin), R1 (microscopically positive resection margin), and R2 (macroscopically positive resection margin) following this regimen.
  • To determine the radiographic response rate to this regimen as defined by conventional RECIST criteria.
  • To obtain preliminary data regarding local disease control, distant disease control, progression-free survival, and overall survival with this regimen.

OUTLINE: This is a phase I dose-escalation study of sorafenib tosylate followed by a phase II study.

Patients receive oral sorafenib tosylate twice daily on days 1-35 and undergo conformal radiotherapy 5 days a week for 5 weeks.

Patients undergo dynamic contrast-enhanced MRI scanning at baseline and day 63 followed by surgical resection on day 70.

After completion of study therapy, patients are followed every 4 months.
