鼻腔原発扁平上皮癌16症例の臨床的検討

Squamous Cell Carcinoma of the Nasal Cavity:Clinical examination of 16 cases

　緒言

　上顎洞に原発する扁平上皮癌はそれほど珍しい疾患ではないが，固有鼻腔に原発する扁平上皮癌は比較的まれである。

　今回われわれは，当院が1962年に開設されて以来31年間に当科において初回治療を行った16例の鼻腔原発扁平上皮癌の臨床経過，治療，予後などにつき若干の考察を加えて報告する。

Sixteen cases of squamous cell carcinoma of the nasal cavity treated at National Cancer Center Hospital were investigated retrospectively. There were 13 men and 3 women, and the average age was 58.3 years old. Nasal obstruction was the most common symptom, followed by epistaxis. Nine tumors arose from the maxillary ostium, and 5 of these were associated with inverted papilloma. Histologically, more than half of the tumors were of moderately differentiated type. Two patients were chromate workers. The cases with inverted papil-loma had better prognosis than the other cases. The cumulative five-year survival rate of all cases was 60.9%.
