Long-term follow-up of patients treated with neoadjuvant chemotherapy and radiotherapy for large, extremity soft tissue sarcomas.

Background: Patients with large, high-grade, extremity soft tissue sarcomas (STS) are at significant risk for distant recurrence and death. A regimen of preoperative chemotherapy consisting of mesna, Adriamycin (doxorubicin), ifosfamide, and dacarbazine (MAID), interdigitated with radiotherapy (RT) and followed by resection and postoperative chemotherapy with or without RT, has demonstrated high rates of local and distant control. We report the long-term follow-up data on 48 patients treated with this regimen compared to an historical matched-control patient population.

Long-term results of a phase 2 study of neoadjuvant chemotherapy and radiotherapy in the management of high-risk, high-grade, soft tissue sarcomas of the extremities and body wall: Radiation Therapy Oncology Group Trial 9514.

Background: The use of neoadjuvant and adjuvant chemotherapy in soft tissue sarcomas is controversial. This is a report of long-term (≥5 years) follow-up in patients with high-grade, high-risk soft tissue sarcomas treated with neoadjuvant chemotherapy, preoperative radiotherapy (RT), and adjuvant chemotherapy.

Methods: Patients with high-grade soft tissue sarcoma≥8 cm in diameter of the extremities and body wall received 3 cycles of neoadjuvant chemotherapy (mesna, doxorubicin, ifosfamide, and dacarbazine) and preoperative RT (44 grays administered in split courses), and 3 cycles of postoperative chemotherapy (mesna, doxorubicin, ifosfamide, and dacarbazine).

Phase II study of high-dose photon/proton radiotherapy in the management of spine sarcomas.

Purpose: Radiotherapy (XRT) for spine sarcomas is constrained by spinal cord, nerve, and viscera tolerance. Negative surgical margins are uncommon; hence, doses of >or=66 Gy are recommended. A Phase II clinical trial evaluated high-dose photon/proton XRT for spine sarcomas.

Phase II study of neoadjuvant chemotherapy and radiation therapy in the management of high-risk, high-grade, soft tissue sarcomas of the extremities and body wall: Radiation Therapy Oncology Group Trial 9514.

Purpose: 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 > or = 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).

Neoadjuvant chemotherapy and radiotherapy for large extremity soft-tissue sarcomas.

Purpose: Treatment of extremity soft-tissue sarcomas yields excellent local control, but distant failure is common with large, high-grade tumors. A regimen of preoperative chemotherapy consisting of mesna, adriamycin, ifosfamide, and dacarbazine (MAID) interdigitated with radiotherapy followed by resection and postoperative chemotherapy with or without radiotherapy was designed to improve treatment outcome. We report the mature outcome data on 48 treated patients and compare them with the data of an historical matched control patient population.
