Background: Thirty adult patients with head and neck soft tissue sarcoma (HNSTS) treated between 1987 and 2000 were retrospectively analysed.
Patients and methods: The most frequent histopathological subtypes were chondrosarcomas (27%) and malignant fibrous histiocytoma (20%). The surgical resection was performed in 25 of the 30 patients (83%). Twenty-three patients in the surgical resection arm received postoperative radiotherapy.
Results: Five-year local control rates for patients with negative surgical margins (n=9), microscopically positive disease (n=10), gross residual disease (n=6) and inoperable cases (n=5) were 64, 70, 20 and 0%, respectively. However, there was no significant difference in local control between patients with negative or microscopically positive disease who received postoperative radiotherapy (71 vs. 70%). The patients who received doses>or=60 Gy had significantly higher local control rates than the ones who received doses lower than 60 Gy (p=0.048). The local control rates were lower in patients with grade 2-3 tumours when compared with grade 1 tumours (44 vs. 83%). The median overall survival of whole group was 31 months. Median survivals of patients receiving both surgery and radiotherapy with negative and microscopically positive margins were significantly better than patients who were not treated with surgery (34.8 and 36 vs. 13.3 months).
Conclusion: Our results confirm that the optimal treatment of HNSTSs is complete surgical excision, and that postoperative adjuvant radiotherapy clearly improves local control.
