Surgical Management of Head and Neck Soft Tissue Sarcoma: 11-Year Experience at a Tertiary Care Centre in South India.

Head and neck soft tissue sarcoma (HNSTS) is a rare neoplasm accounting for 1% of all head and neck tumours. Because of rarity and varied biological behaviour among various subtypes, knowledge about these tumours is limited. This study aimed at analysing clinicopathological, recurrence and survival pattern of surgically treated HNSTS. Case records of 28 patients of HNSTS who underwent surgery at the Regional Cancer Centre (RCC), Trivandrum (India) between 2002 and 2012 were analysed retrospectively for demographic profile, clinical features, treatment given, recurrence pattern and outcome. The median age of patients was 37 years (range, 3-79) with male:female ratio of 3:2. Majority of patients presented with painless lump in the neck as the most common subsite affected followed by scalp and face. One patient had nodal disease, while none had distant metastasis at presentation. The most frequent histological subtypes were synovial sarcoma and fibrosarcoma followed by malignant fibrous histiocytoma, angiosarcoma and rhabdomyosarcoma. Majority (78.5%) of patients received adjuvant therapy in the form of radiation, chemotherapy or chemo-radiation. After mean follow-up of 49 months, four patients had died, and six developed local recurrence and four distant metastasis. The overall 5-year survival was 82.7% while 5-year disease-free survival was 55.3%. HNSTS is a rare entity that requires multimodality treatment to achieve optimum locoregional control and survival.
