日本病理剖検輯報に基づく舌癌剖検症例の統計的検討（第ＩＶ報）

Abstract

To study malignant neoplasms of the tongue in Japan, we statistically analyzed autopsy cases of malignant neoplasms of the tongue reported in the Annals of Pathological Autopsy Cases in Japan during a 5 -year period (1987-1991). The following results were obtained.1. A total number of 473 cases (337 males, 136 females) of malignant neoplasms of the tongue were reported.2. Among patients who died of malignant neoplasms of the tongue, the autopsy rate was 14.5%.3. Malignant neoplasms of the tongue were found most frequently in the seventh decade (29.6%), followed by the eighth decade (24.7%) and sixth decade (20.9%).4. Histologically 96.6% of malignant neoplasms of the tongue were squamous cell carcinoma.5. Squamous cell carcinoma most frequently arose in the lateral border of the tongue (53. 5%), followed by the root of the tongue (28.9%).6. With respect to organ metastasis, the lung was the most common site, followed by the liver, bone, skin and thyroid. With regard to the lymph nodes, the cervical nodes were the most frequently invaded, followed by the pulmonary hilar, laryngeal, paraesophageal and paratracheal nodes.7. Multiple primary cancers, affecting both the tongue and other organs, were found in 123 cases (96 males, 27 females).8. The most common cause of death not associated with malignant neoplasms of the tongue was pulmonary infection.
