[Disparities of sex on cancer incidence and mortality in Jiashan county, Zhejiang province,1990-2014].

Objective

This study aimed to describe the sex disparities on cancer incidence and mortality in Jiashan population.

Methods

All data concerning incident and death cases of cancers were gathered from the database of Cancer Registry in Jiashan county. Data from the 2010 China census was used as the standard population. Sex-specific age-standardized incidence rates (ASIRs), mortality rates (ASMRs) per 100 000 persons for all cancers and types of each cancer were calculated for the years of 1990 to 1999, 2000 to 2009, 2010 to 2014, and 1990 to 2014. In addition, the corresponding male-to-female incidence rate ratios (IRRs) and mortality rate ratios (MRRs) were also calculated.

Results

The ASIR of all cancers was 226.13/10(5) for the whole period of 1990 to 2014, with 266.04/10(5) for males and 187.22/10(5) for females, respectively. The corresponding IRR was 1.42 (95%CI: 1.39-1.46), with significant difference noticed in the incidence rates between males and females (P<0.05). The ASMR of all cancers was 155.39/10(5), with 206.55/10(5) for males and 104.98/10(5) for females, respectively. The corresponding MRR was 1.97 (95% CI: 1.91-2.03), with significant difference between males and females (P<0.05). Among all the cancer types, only gallbladder cancer and thyroid cancer showed female predominance in both incidence and mortality, with male predominance in all the remaining cancers.

Conclusion

Finding from our study suggested that a male predominance in both incidence and mortality for a majority of cancers in Jiashan population.
