Squamous cell carcinoma of the maxillary sinus

Area of Science:

• Oncology
• Otorhinolaryngology
• Radiation Oncology

Background:

• Squamous cell carcinoma of the maxillary sinus is a rare malignancy.
• Advanced stage (T3 and T4) lesions present significant treatment challenges.

Purpose of the Study:

• To evaluate the efficacy of combined surgery and radiation therapy versus radiation alone for maxillary sinus squamous cell carcinoma.
• To compare treatment outcomes, including lesion control and survival rates, for different therapeutic approaches.

Main Methods:

• Retrospective analysis of 59 patients with maxillary sinus squamous cell carcinoma.
• Patients were treated with either radiation alone or combined surgery and radiation therapy.
• Analysis focused on T3 and T4 lesions, comparing local control and five-year actuarial survival rates.

Main Results:

• Combined therapy achieved a 66.6% control rate for T3/T4 lesions, compared to 34% for radiation alone.
• Five-year survival for T3/T4 patients was 75% with combined therapy versus 38.4% with radiation alone.
• Overall five-year survival for the entire cohort was 39.3%.

Conclusions:

• Combined surgery and radiation therapy demonstrates superior efficacy in controlling advanced maxillary sinus squamous cell carcinoma.
• Selected patients may benefit from a treatment strategy involving surgery followed by adjuvant radiation therapy.
• Further investigation into optimizing combined treatment protocols is warranted.
