| 摘 要：［目的］ 分析中国恶性肿瘤性别发病差异情况。［方法］ 利用全国肿瘤登记中心收集的全国2009 年恶性肿瘤发病数据以及相应的人口数据，运用负二项回归模型校正年龄、地区因素后，分析恶性肿瘤的性别发病差异。［结果］ 2009年全国肿瘤登记地区恶性肿瘤发病率为285.91/10 万，其中男性发病率为317.97/10 万，女性为253.09/10 万，男性发病率比女性高61%，发病相对指数为1.61倍（95%CI:1.45~1.79）。在所有部位恶性肿瘤中，仅有甲状腺癌女性显著高于男性，脑和神经系统肿瘤两性差异没有显著性，其余常见恶性肿瘤均为男性显著高于女性。城市地区性别发病相对指数显著高于农村地区的恶性肿瘤有食管癌和肝癌，发病相对指数明显低于农村地区的恶性肿瘤有胃癌和膀胱癌。［结论］ 我国不同部位恶性肿瘤发病存在明显的性别差异，城市地区和农村地区各有其特点，应针对不同情况开展更有针对性的肿瘤防治工作。 |

| Abstract:［Purpose］ To analyze the cancer incidence rate ratio between male and female in China，2009.［Methods］ The National Cancer Registration Center collected the cancer cases data and population data in China，2009. The cancer incidence rate ratio between male and female was fitted by negative binomial regression model adjusted for age，areas factors.［Results］ The crude incidence rates were 317.97/105 for male and 253.09/105 for female. Compared to female，the cancer incidence rate ratio was 1.61(95%CI:1.45~1.79) for male. Among all cancers，only thyroid gland cancer incidence rate ratio was less than 1; brain and central nervous system cancer incidence rate ratio was around 1，with no statistical significance. The incidence rates of other cancers were much higher in male than those in female. The incidence rate ratios of esophageal cancer and liver cancer in urban areas were higher than those in rural areas. The incidence rate ratios of stomach cancer and bladder cancer in urban areas were lower than those in rural areas. ［Conclusion］ The cancer incidence is significantly different between male and female，so we should use different pattern to prevent and control cancer according to different gender. |
