Epidemiological Study of Head and Neck Sarcomas

Area of Science:

• Oncology
• Surgical Pathology
• Epidemiology

Background:

• Head and neck sarcomas are rare malignancies, comprising <1% of head and neck cancers and <5% of all sarcomas.
• Understanding the epidemiological patterns and treatment outcomes of these tumors is crucial for improving patient care.

Purpose of the Study:

• To assess the epidemiological patterns of head and neck sarcomas in Isfahan, Iran.
• To investigate treatment modalities, recurrence rates, and overall survival (OS).
• To compare findings with existing literature and identify prognostic factors.

Main Methods:

• A retrospective study of 160 patients diagnosed with head and neck sarcoma between 2001 and 2020.
• Data collected included demographics, tumor characteristics, treatment, recurrence, and survival (2- and 5-year OS).
• Investigation of disease recurrence and survival rates via phone follow-up.

Main Results:

• The majority of patients were male (58.8%) with a mean age of 36.9 years.
• The neck was the most common site (21.3%), and undifferentiated pleomorphic sarcoma was the most frequent type (30.0%).
• Metastasis was present in 55.6% of patients, with high 2-year (62.5%) and 5-year (68.8%) recurrence rates and 2-year (64.4%) and 5-year (36.6%) OS.

Conclusions:

• Metastasis significantly correlated with both recurrence rates and overall survival.
• Patients treated with surgery alone demonstrated significantly higher 2-year and 5-year overall survival rates compared to other treatment groups.
