口腔重复癌由Sarasin氏在1933年首次报告以来,发现率似有逐年增多的倾向。作者就口腔癌97例的尸检研究和1961—1975年日本文献中的口腔癌尸检2872例进行分析总结,以探讨重复癌的某些生物学和临床特征。重复癌的诊断标准重复癌是人体不同脏器同时或不同时发生组织类型不同的原发性肿瘤。根据Warren和Gates氏提出的重复癌诊断标准为:①每个肿瘤都有其明确的恶性组织图象。②每个肿瘤发生于不同的部位。③排除转移瘤的可能性。
Oral repetitive cancers were first reported by Sarasin’s in 1933, and the rate of discovery seems to have increased year by year. The authors conducted an autopsy study of 97 cases of oral cancer and 2872 autopsy of oral cancer in the Japanese literature from 1961 to 1975 to discuss certain biological and clinical features of the repeat cancer. Repeated cancer diagnostic criteria Repeated cancers are primary tumors with different tissue types occurring simultaneously or at different times in different organs of the body. According to Warren and Gates’s repetitive cancer diagnostic criteria: 1 Each tumor has its definitive image of malignant tissue. 2 Each tumor occurs at a different site. 3 Remove the possibility of metastases.
