Management of Stage II Sinonasal Carcinoma (T2N0M0) with Transnasal Endoscopic Resection and Radiotherapy

Abstract

Nasoethmoidal carcinoma is a malignant tumor found in the nasal cavity and ethmoidal sinuses. The early stage is rarely found due to the similarity of symptoms inflammatory process in sinonasal. The main modality for sinonasal cancer is surgery followed by radiation as adjuvant treatment. The prognosis for early-stage sinonasal malignancy is generally good, which found a low recurrence rate. This study aims to report the management of early-stage sinonasal carcinoma. A 44-years-old male with the main symptom of left nasal blockage and bleeding since 6 months ago, physical examination showed a solitary mass at the posterior nasal septum. Histopathology result was welldifferentiated squamous cell carcinoma and Paranasal sinuses CT-Scan showed a solid mass in left posterior nasal cavity extended to ethmoidal sinuses. He underwent transnasal endoscopic resection, and we suggested continuing with radiotherapy at central java. Follow-up 2 months after radiotherapy, we performed a biopsy, and histopathology revealed a chronic inflammatory process without malignancy, paranasal sinuses CT Scan n physical examination within normal limits. Transnasal endoscopic resection followed by radiotherapy is an appropriate and effective treatment for sinonasal carcinoma in the early stage. A case of limited-stage II sinonasal carcinoma with transnasal endoscopic resection surgery followed by radiotherapy has been reported with good result and need to be followed until the next five years.
