恶性肿瘤７８４０例临床病理资料分析结果表明：①恶性肿瘤占临床病理检验总病例数的１７．５８％（７８４０／４４５９７）．年均病例数为６５３．３例。②２５种恶性肿瘤的构成比由高到低依次是胃癌和宫颈癌（二者并列第一）、大肠癌、鼻咽癌、乳腺癌、食管癌、恶性淋巴瘤、肺癌、喉癌、卵巢癌、皮肤癌、宫体癌、甲状腺癌、骨肿瘤、肝癌、膀胱癌、外阴及阴道癌、脑肿瘤、肾癌、绒癌、扁桃体癌、胰腺癌、胆囊癌、睾丸癌、前列腺癌及其它。③近年来，宫颈癌和鼻咽癌的构成比呈下降的趋势，胃癌的病例数也有所减少，而乳腺癌病例数则呈增多的趋势。④８０年代初（１９８１～１９８２）与９０年代初（１９９１～１９９２）比较，不同肿瘤的病例数出现了明显的变化，８０年代初，病例数较多的恶性肿瘤依次是宫颈癌、胃癌、大肠癌、鼻咽癌、乳腺癌、食管癌等；而９０年代则依次是胃癌、乳腺癌、大肠癌、宫颈癌、肺癌等。⑤女性恶性肿瘤病例数多于男性，女性占５５．７０％（４３６７／７８４０）．男性占４４．３０％（３４７３／７８４０）．男女之比为１：１．２６。
The results of clinical and pathological analysis of 7840 malignant tumors showed that: ① malignant tumors accounted for 17.58% (7840/44597) of the total number of clinical pathological examination. The average annual number of cases was 653.3 cases. ② The proportions of 25 kinds of malignant tumors were as follows: gastric cancer and cervical cancer (the first two were tied together), the colon cancer, nasopharyngeal cancer, breast cancer, esophageal cancer, malignant lymphoma, lung cancer, laryngeal cancer, ovarian cancer, Cancer of the uterus, thyroid cancer, bone cancer, liver cancer, bladder cancer, vulvar and vaginal cancer, brain tumor, kidney cancer, choriocarcinoma, tonsil cancer, pancreatic cancer, gallbladder cancer, testicular cancer, prostate cancer and others. ③ In recent years, the composition of cervical cancer and nasopharyngeal carcinoma has a declining trend, the number of cases of gastric cancer has also decreased, while the number of cases of breast cancer showed an increasing trend. ④ The number of different tumors showed obvious changes in the early 1980s (1981 ~ 1982) and the early 1990s (1991 ~ 1992). In the early 1980s, the number of malignant tumors with more cases were followed by cervical cancer, gastric cancer, colorectal cancer , Nasopharyngeal cancer, breast cancer, esophageal cancer, etc .; while the 1990s followed by gastric cancer, breast cancer, colorectal cancer, cervical cancer, lung cancer. ⑤ More cases of malignant tumors in women than men, women accounted for 55.70% (4367/7840). Men accounted for 44.30% (3473/7840). The ratio of male to female is 1: 1.26.
