title: [Multidisciplinary treatment of soft tissue sarcomas: an improvement in prognosis (author's transl)].
abstract: The results obtained in the treatment of 45 cases of soft tissue sarcomas are presented. All cases were reviewed and classified according to the modern criteria of malignancy. The treatment schedule comprised: (1) preoperative irradiation: 2 sessions of 6.50 Gy in 48 hours, target volume: whole limb segment; (2) surgical excision 48 hours later with systematic intraoperative histologic verification, until healthy tissue margins are obtained; (3) postoperative irradiation: 3 weeks later delivering a cumulative total dose of 50.00 Gy to the preoperative volume and 60.00 - 70.00 Gy to a reduced volume encompassing the surgical region with protection of vascular axes where possible; (4) chemotherapy: Actinomycin D 0.3 mg/m2 half and hour before the first 5 sessions of postoperative irradiation; (5) bilateral lung irradiation: 4 sessions of 3.75 Gy in 7 days to the whole chest. The results were as follows: local recurrence rate was 9.5 per cent at 5 years. In 21 cases in whom surgical excision was deemed histologically adequate, no recurrences was seen at 3 years (minimum follow-up). Survival at 5 years was 77 per cent. Deaths were due to metastatic spread, especially to the lungs. These results show an improvement as compared with historical series. New progress should be sought in combining a more aggressive type of chemotherapy for cases with high metastatic risk.
