目的了解温州市居民的恶性肿瘤发病水平和分布特征,为防治提供科学依据。方法利用2010-2011年温州市恶性肿瘤发病数据,描述恶性肿瘤的城乡、性别和年龄分布特征。对资料拟合负二项分布,分析恶性肿瘤发病是否存在空间聚集性。结果 2010-2011年温州市恶性肿瘤新发病例22 378例,其中,男性发病13 229例,女性发病9 149例,平均报告发病率为145.26/10万,标化发病率为121.39/10万,男性发病率为165.29/10万,女性发病率为123.60/10万。2010-2011年温州市恶性肿瘤平均发病率居前5位的依次为肺癌、胃癌、肝癌、肠癌和乳腺癌;男性恶性肿瘤发病率居前5位的依次为肺癌、胃癌、肝癌、肠癌和食管癌;女性发病率居前5位的依次为乳腺癌、肺癌、肠癌、宫颈癌和胃癌。男性食管癌发病率为10.10/10万,标化率为7.91/10万,女性食管癌发病率为1.82/10万,标化率为1.50/10万。鼻咽癌和宫颈癌聚集参数k分别为0.73(P>0.05)和1.12(P>0.05)。结论男性食管癌发病率和标化率明显高于女性,鼻咽癌和宫颈癌存在空间聚集性。
Objective To understand the incidence and distribution of malignant tumors in Wenzhou residents and provide scientific basis for prevention and treatment. Methods The incidence of malignant tumors in Wenzhou City from 2010 to 2011 was used to describe the characteristics of urban and rural areas, sex and age distribution of malignant tumors. A negative binomial distribution was fitted to the data to analyze whether there was spatial clustering in the incidence of malignant tumors. Results There were 22 378 new cases of malignant tumors in Wenzhou City from 2010 to 2011, among which 13 229 cases were male and 9 149 were female. The average reported incidence rate was 145.26/100000, and the standardized incidence was 121.39/100000. The incidence rate for males is 165.29/100,000 and the female incidence rate is 123.60/100,000. The top five rankings of the average incidence of malignant tumors in Wenzhou from 2010 to 2011 were lung cancer, stomach cancer, liver cancer, colorectal cancer, and breast cancer. The top five cancer incidence rates for males were lung cancer, stomach cancer, liver cancer, and intestine cancer. And esophageal cancer; The top five incidence rates for women were breast cancer, lung cancer, colon cancer, cervical cancer, and gastric cancer. The incidence rate of male esophageal cancer was 10.10 per million, the standardized rate was 7.91 per 100,000, and the incidence of female esophageal cancer was 1.82 per 100,000. The standardized rate was 1.50 per 100,000. The clustering parameters of nasopharyngeal carcinoma and cervical cancer were 0.73 (P>0.05) and 1.12 (P>0.05). Conclusions The incidence and standardized rate of male esophageal cancer are significantly higher than that of women. There is spatial aggregation in nasopharyngeal carcinoma and cervical cancer.
