Adjuvant therapies utilization pattern and survival outcomes in high-grade head and neck soft tissue sarcoma; a population based study

Head and neck soft tissue sarcomas (HNSTS) are a rare and heterogeneous group of mesenchymal neoplasms with more than 50 different histologic subtypes that account for only 2–15% of soft tissue sarcomas and 1% of head and neck tumors [1].
