Incidence and mortality of thyroid cancer in six cancer registries of Zhejiang province, 2000-2009 / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the incidence and mortality rates of thyroid cancer in Zhejiang province during 2000 to 2009.</p><p><b>METHODS</b>The data of thyroid cancer were collected from six cancer registries in Zhejiang province and the incidence and mortality rates of thyroid cancer were analysed.</p><p><b>RESULTS</b>The mean annual incidence rate of thyroid cancer in Zhejiang cancer registration areas was 6.93/100 000 during 2000 to 2009, and male/female ratio was 1: 3.43. The incidence rate was 3.62/100 000 in 2000 and it increased to 11.42/100 000 in 2009, with the annual percent change (APC) of 16.32% (95% confidence interval: 12.90%-19.85%). The mean annual mortality rate of thyroid cancer was 0.27/100 000 during 2000 to 2009, and male/female ratio was 1: 1.12. The mortality showed a rising trend without a distinct fluctuation from 2000 to 2009, the APC was 2.14% (95% confidence interval: from -7.10% to 12.30%). The incidence showed a rising trend with the increase of ages after 15 years old, and peaked at 55-60 years old. The mortality was low before 54 years old, but showed a rising trend with a distinct fluctuation after 55 years old, and peaked at 85-90 years old.</p><p><b>CONCLUSION</b>The prevention and control of risk factors for thyroid cancer in young and middle-aged people is key to decrease the incidence and mortality of thyroid cancer.</p>

Incidence and mortality of brain tumor in areas with cancer registration of Zhejiang province,from 2000 to 2009 / 中华流行病学杂志

Objective To investigate the incidence and mortality of brain tumor in Zhejiang cancer registration areas from 2000 to 2009.Methods Data from 6 Cancer registration areas of Zhejiang province were collected.Number of cases,crude rates,proportions,age standardized rates,cumulate rates,cut rates,age-specific rates and annual percentage change (APC,95％ CI) of brain tumor incidence and mortality were analyzed.Results There were 5 123 new diagnosed brain tumor cases in Zhejiang cancer registration areas,accounting for 3.14％ of all the new cancer cases.The incidence rate of brain tumor was 8.53/100 000,and the standardized incidence rate by Chinese population was 5.72/100 000,ranking the 7th in cancer incidence spectrum of anatomic sites.Agespecific incidence of brain tumor increased along with age,and peaked among 70-74 age groups (24.09/100 000).The annual incidence rate of brain tumor increased from 2000 (6.87/100 000) to 2009 (8.35/ 100 000),with APC as 1.58％ (95 ％ CI:-2.17％-5.47％,no statistical significance).A total of 2 357 deaths caused by brain tunor were reported from 2000-2009,accounting for 2.47％ of all the cancer death cases.Mortality rate on brain tumor appeared to be 3.92/100 000,with the standardized mortality rate by Chinese population as 2.45/100 000,ranking the 7th in cancer mortality spectrum of anatomic sites.The age-specific mortality of brain tumor remained low among 0-39 year-olds,and reached the peak at 80-84 age groups (17.64/100 000).The annual mortality rate of brain tumor decreased from 2000 (4.30/100 000) to 2009 (3.83/100 000) with minor fluctuation,and the APC was-0.65％ (95％CI:-3.35％-2.12％,no statistical significance).Conclusion Brain tumors incidence and mortality in Zhejiang cancer registration areas were at a relatively high level.People who were at middle-age,especially above 70 years old should be the key targets for protection on this disease.Brain tumor incidence rates increased annually in Zhejiang,which should be called for attention.

Analysis of incidence and mortality of prostate cancer in cancer registration area in Zhejiang province from 2000 to 2009 / 中华泌尿外科杂志

Objective To investigate the epidemic characteristics and trends of incidence and mortality of prostate cancer in cancer registration areas in Zhejiang province from 2000 to 2009.Methods Clinical data incidence and mortality of prostate cancer were collected from 6 cancer registration areas in Zhejiang province,including Hangzhou,Jiaxing,Jiashan,Haining,Shangyu and Xianju.Crude rates,standardized rate and change trend,age-specific rates and annual percent change (APC,95％ CI) of prostate cancer were checked,sorted and analyzed in Zhejiang Cancer Center.Results The prostate cancer incidence rate from 2000 to 2009 was 9.79/100 000,age-standardized incidence rates by world standard population (ASIRW) was 6.39/100 000,and the incidence cumulative risk of males aged 0-74 was 0.72％ ; while the mortality rate was 2.73/100 000,age-standardized mortality rates by world standard population was 1.74/100 000,and the mortality cumulative risk of males aged 0-74 was 0.14％.Age-specific incidence of prostate cancer remained low before 50,years old and peaked at over 85-year-old group (130.30/100 000).Age-specific mortality of prostate cancer increased after 55,and also peaked at over 85-year-old group (81.19/100 000).The annual prostate cancer incidence rate generally grew from 1.39/100 000 (2000) to 13.89/100 000 (2009),and the APC was 14.18％ (95％ CI,9.68％-18.98％).Meanwhile,the prostate cancer mortality rate also increased from 1.52/100 000 (2000) to 3.58/100 000 (2009),and the APC was 11.83％ (95％ CI,5.69％-18.33％).Conclusion Prostate cancer incidence and mortality in Zhejiang cancer registration areas increased sharply,and the prevention and treatment of prostate cancer should be strengthened.
