Objective : To analyze the trends in incidence of thyroid cancer in Huangpu District, Shanghai from 2002 to 2017, so as to provide insights into the management of thyroid cancer. Methods : The incidence of thyroid cancer in Shanghai from 2002 to 2017 was collected from the cancer registration system created by Shanghai Center for Disease Control and Prevention. The crude and standardized incidence of thyroid cancer were estimated by year, gender and age groups, and annual change percentage ( APC ) was calculated to analyze the trends in incidence of thyroid cancer. Results : A total of 2 854 new cases of thyroid cancer were reported in Huangpu District from 2002 to 2017, and the crude and standardized incidence rates of thyroid cancer were 19.57/105 and 13.47/105, with APC of 18.15% and 17.93% ( P<0.05 ), respectively. The crude and standardized incidence rates of thyroid cancer were 10.02/105 and 7.06/105 in men, with APC of 19.58% and 19.04% ( P<0.05 ), and were 28.90/105 and 19.95/105 in women, with APC of 17.33% and 16.99% ( P<0.05 ), respectively. The crude incidence of thyroid cancer was higher in women than in men ( P<0.05 ). In addition, there were two peaks in the crude incidence of thyroid cancer in patients at age of 35 to 39 and 60 to 64 years, with crude incidence rates of 28.98/105 and 33.36/105, respectively. Conclusions The incidence of thyroid cancer appeared a tendency towards a rise in Huangpu District from 2002 to 2017, and much attention should be paid to females and patients aged 60 to 64 years.

Objective: To investigate the trends in incidence and mortality of prostate cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide insights into the prevention and treatment of prostate cancer. Methods: The incidence and mortality of prostate cancer among men in Huangpu District from 2002 to 2019 were collected from the Shanghai Cancer Registry System. The crude incidence, crude mortality, truncated age-standardized incidence (aged 35 to 64 years) and cumulative incidence (aged 0 to 74 years) of prostate cancer were calculated. The Chinese Fifth National Population Census in 2000 and the Segi's world standard population in 1960 were used to calculate Chinese-standardized rate and world-standardized rate. The trends in incidence and mortality of prostate cancer were evaluated using annual percent change (APC) and average annual percent change (AAPC). Results: A total of 2 672 cases of prostate cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence was 33.35/105, the Chinese-standardized incidence was 14.93/105 and the world-standardized incidence was 12.37/105 (AAPC=7.675%, 4.886% and 4.983%, all P<0.05). The incidence of prostate cancer among males at ages of 60 to <70 years and 70 to <80 years appeared increasing trends (AAPC=4.554% and 5.045%, both P<0.05). A total of 1 214 deaths of prostate cancer were reported, and the crude mortality was 15.15/105, the Chinese-standardized mortality was 6.01/105 and the world-standardized mortality was 4.61/105 (AAPC=5.500%, 2.057% and 1.784%, all P<0.05). The mortality of prostate cancer among males at ages of 80 years and above appeared an increasing trend (AAPC=4.220%, P<0.05). Conclusions The incidence and mortality of prostate cancer appeared increasing trends in Huangpu District from 2002 to 2019, and the incidence among males at ages of 60 years and above also increased. The screening for prostate cancer among males at ages of 60 years and above should be strengthened.

Objective To explore the association of CD22 gene T＞A locus (SNPrs2267574) with the development of systemic lupus erythematosus (SLE) and SLE phenotypes in Southern Chinese Han people.Methods Two hundreds fifteen cases and 216 normal controls were enrolled with the aim of case-control design,and the genotype was determined by PCR-RFLP.We calculated X2 and ORs for association study.Results In CD22 gene T＞A locus,there was significant difference of genotypes distribution between cases and controls (X2=6.086,P＜0.05).The frequency of AT genotype was higher in cases than in controls (OR=1.68,95%CI:1.08～2.60,P=0.021 ),and A allele had a higher proportion in cases (OR=1.58,95%CI:1.09～2.29,P=0.015).Meanwhile,the frequency of A allele in patients with positive anti-SSA was higher than in patients with negative anti-SSA (OR=3.69,95%CI:2.08～6.52,P＜0.01 ).Conclusion In Southern Chinese Han population,CD22 gene T＞A locus is associated with the development of SLE and the A allele has positive association with anti-SSA.
