Abstract:
On the basis of a positive reported single-institution pilot study, the Radiation Therapy Oncology Group initiated phase II trial 9514 to evaluate its neoadjuvant regimen in a multi-institutional Intergroup setting. Patients and Methods Eligibility included a high-grade soft tissue sarcoma ≥ 8 cm in diameter of the extremities and body wall. Patients received three cycles of neoadjuvant chemotherapy (CT; modified mesna, doxorubicin, ifosfamide, and dacarbazine [MAID]), interdigitated preoperative radiation therapy (RT; 44 Gy administered in split courses), and three cycles of postoperative CT (modified MAID). Results Sixty-six patients were enrolled, of whom 64 were analyzed. Seventy-nine percent of patients completed their preoperative CT and 59% completed all planned CT. Three patients (5%) experienced fatal grade 5 toxicities (myelodysplasias, two patients; infection, one patient). Another 53 patients (83%) experienced grade 4 toxicities; 78% experienced grade 4 hematologic toxicity and 19% experienced grade 4 nonhematologic toxicity. Sixty-one patients underwent surgery. Fifty-eight of these were R0 resections, of which five were amputations. There were three R1 resections. The estimated 3-year rate for local-regional failure is 17.6% if amputation is considered a failure and 10.1% if not. Estimated 3-year rates for disease-free, distant–disease-free, and overall survival are 56.6%, 64.5%, and 75.1%, respectively. Conclusion This combined-modality treatment can be delivered successfully in a multi-institutional setting. Efficacy results are consistent with previous single-institution results.
