目的探讨恶性肿瘤的流行特征,为病因假说提供线索,并对癌症预防提供依据。方法通过建立恶性肿瘤登记报告制度获取发病资料,按《中国恶性肿瘤登记工作指导手册》介绍的方法计算中国人口调整率(中调率)、世界人口调整率(世调率)、35～64岁世界人口截缩调整率(截缩率)、0～74岁累积率(累积率)等统计指标。结果2001～2005年恶性肿瘤年平均粗发病率为229.32/10万,中调率为202.32/10万,世调率为262.74/10万,截缩率为522.03/10万,累积率为39.17%。性比值(男/女)为1.92。年龄性别发病率有随年龄增长而升高的趋势。男性前9位恶性肿瘤依次为胃癌、食管癌、肺癌、大肠癌、肝癌、恶性淋巴瘤、白血病、胆囊及肝外胆管癌、胰腺癌;女性前11位恶性肿瘤依次为胃癌、食管癌、乳腺癌、肺癌、大肠癌、宫颈癌、肝癌、胆囊及肝外胆管癌、恶性淋巴瘤、白血病、胰腺癌。结论武威市恶性肿瘤发病率呈上升趋势,胃癌、食管癌男女均居前1、2位。
Objective To investigate the epidemiological characteristics of malignant tumors and provide clues for the cause hypothesis and provide basis for cancer prevention. Methods The incidence information was obtained through the establishment of the reporting system of malignant tumors, and the population adjustment rate (intermediate adjustment rate), world population adjustment rate (world adjustment rate) and 35-64 years old were calculated according to the method described in the “Guidelines for the Registry of Malignant Tumors in China” World population truncation adjustment rate (cut-off rate), 0 to 74-year-old cumulative rate (cumulative rate) and other statistical indicators. Results The average annual incidence of malignant tumors from 2001 to 2005 was 229.32 / lakh, with a medium transfer rate of 202.32 / lakh and an annual rate of 262.74 / lakh. The truncation rate was 522.03 / lakh and the cumulative rate was 39.17% . Sex ratio (male / female) was 1.92. Age and gender morbidity increase with age. The top 9 malignant tumors in men were gastric cancer, esophageal cancer, lung cancer, colorectal cancer, liver cancer, malignant lymphoma, leukemia, gallbladder and extrahepatic bile duct cancer and pancreatic cancer. The top 11 malignant tumors in women were gastric cancer, esophageal cancer, breast Cancer, lung cancer, colorectal cancer, cervical cancer, liver cancer, gallbladder and extrahepatic bile duct cancer, malignant lymphoma, leukemia, pancreatic cancer. Conclusions The incidence of malignant tumors in Wuwei City is on the rise, with the first and second rankings in gastric cancer and esophageal cancer.
