【摘要】 自1995年1月至1996年1月我们对陕西省宝鸡地区的凤县、眉县及岐山县80余万人进行了1992～1994年恶性肿瘤发病及死亡调查。共查出30种恶性肿瘤1291例病人。结果与70年代全国恶性肿瘤普查资料比较可见，恶性肿瘤平均死亡年龄乳腺癌明显下降，恶性淋巴瘤、白血病上升。性别比鼻咽癌和脑瘤明显上升。粗死亡率和标化死亡率除肺癌以外均有不同程度的下降，以食道癌最著。死亡位次，肝癌由原来的第3位上升为第1位，食道癌则由原来的第1位下降为第4位。前5位依次是肝、胃、肺、食道、肠癌。消化系癌（肝、胃、食道、肠、胆囊、胰腺癌）死亡占所有癌症总死亡的64．27％，为该地区爆死亡的主要原因。更多还原

【Abstract】 From Jan. 1995 to Jan. 1996, an investigation on the mortality of malignant tumours in three counties, Feng, Mei, Qishan, in Baoji area Shanxi Province during 1992 - 1994, had been carried out. Comparing the results of this study to the results from the cancer survey carried out in 1970’ in China,we noticed that the average ages of death to breast cancer had decreased but deaths to lymphoma and leukemia had increased dramatically. Sex ratios (male/female)of nasopharyngeal carcinoma and brain tumor had also increased dramatically. However,crude mortalities and age standardized mortalities decreased with esophageal cancer the most in all types of cancers except cancer of the lung. Comparing the ranking of cancer death rates with that of the 1970’s,liver cancer upgraded from the 3rd place to the 1st,but esophageal cancer descended from the 1st to the 4th place. Cancers topped the first 5 places were: liver, stomach, lung, esophagus and colon. The proportion of deaths from cancers of the digestive system cancers including liver,stomach,esophagus, gallbladder and pancreas was 64. 27%. Death due to cancers from digestive system was the main part of all deaths caused by all types of cancers in this area.更多还原
