ObjectiveThe aim of this study was to evaluate nationwide gynecological cancer trends in Turkey.MethodsNational cancer registry data (2009–2013) of Turkish Ministry of Health were evaluated. Ovarian, cervical, endometrial, vulvar, vaginal, and tubal cancers are evaluated with respect to age of diagnosis, incidence rates within years, stage, histological distributions, and mortality rates. Data were collected from active cancer registry centers, which increased from 23% in 2009 to 47.5% coverage of the whole population by 2012, and mortality data (2010–2015) were obtained from the Turkish Statistical Institute.ResultsA total of 16,023 gynecological cancers were evaluated among 116,940 female patients with cancer (13.7%). Average incidence for gynecological cancers was 22.7 of 100,000, representing 8437 total new cases annually. Incidence changes within time were not statistically significant, when evaluated for each tumor type. Estimated risk of gynecological cancer development before the age of 80 years was 3.08% (95% confidence interval, 3.07–3.09). The most common gynecological cancers were uterine corpus cancers, which were followed by ovarian and cervical carcinomas. Ovarian and uterine cancer incidences were closer to European levels rather than Asian countries, whereas cervical cancer incidence was extremely low. Gynecological cancers constituted an important fraction of cancer-related mortality in women by comprising approximately 10.35% of cancer-related deaths. Mortality rates due to gynecological cancers did not show a statistically significant increase within years.ConclusionsThis is the first national cancer registry report to be published for gynecological cancers by the Turkish Governmental Department. As a result, Turkish gynecological cancer epidemiological data were consistent with the data obtained from European and developed countries rather than Asian countries, except for cervical cancer incidence, which is extremely low.

Background: Uruguay is the southamerican country which has the highest cancer incidence and mortality rates. The National Cancer Registry collects data on cancer cases nationwide since 1989 and has reached high quality standards in the last decades. This is the first report on incidence trends. Methods: Data from the National Cancer Registry of all new cases of invasive cancer from twelve sites diagnosed in 2002-2015 was analyzed. Age-standardized rates were calculated. Trends of incidence rates were analyzed using joinpoint regression models. Results For both, men and women, incidence rates trends for all cancer sites, colo-rectal and bladder cancer remained stable. Esophageal and gastric cancers descend while Thyroid and kidney cancer incidence increased. In men lung cancer decreased; testicular cancer increased, and prostate cancer increased at the beginning of the period and decreased in the final years. In women; lung cancer increased, breast cancer remained stable and cervical cancer presented a significant decline from 2005 to 2010 and reached a plateau since then. Conclusion: Cancer incidence dynamics are complex and affected not only by Public Health policies such as tobacco control, vaccination and screening programs, but also by environmental and life style changes and the attitude of the medical community towards the application of diagnostic and therapeutic tools. The aim of this paper is to analyze cancer incidence time trends in the country and provide possible explanations to them.

Background: Cancer is one of the most important causes of death in the world and has an increasing trend globally. We aimed at investigating the five leading cancers in Iranian women based on a 10-year history of cancer registry reports and illustrating the trends in all cancer sites and breast cancer as the top leading one from 2003 to 2015. Methods: Data were obtained from national cancer registry study. Age-Specific Incidence Rate (ASR) data were obtained from Iran’s annual national cancer registry reports between 2003 to 2010 and 2014 to 2015. Using Joinpoint regression, we analyzed incidence trends over time for all cancer sites and the top leading cancer from 2003 to 2015. Results: Breast cancer was ranked first in Iranian women. Its ASR raised from 15.96 in 2003 to 32.63 in 2015. Results of trend analysis based on Annual Percent Change (APC) index showed 5.6 (95%CI: 2.9 to 8.3) and 4.6 (95%CI: 2.0 to 7.2) annual increase in the incidence of all cancer sites and breast cancer from 2003 to 2015, respectively. Conclusion: This study indicates significant increasing trends in all cancer sites and breast cancer incidence in Iran. Despite the national coverage of cancer registry over the past decade, more considerations should be taken into account, especially in Breast cancer.

ABSTRACT BackgroundSub-Saharan Africa is the region most heavily affected by the HIV/AIDS epidemic. HIV increases the risk of developing cancer but the ascertainment of cancers in patients attending antiretroviral therapy (ART) treatment programs might be incomplete. To estimate the under-ascertainment of cancer we compared incidence rates of AIDS-defining cancers in South African HIV cohorts with and without cancer case ascertainment through record linkage with the National Cancer Registry. MethodsWe used the data of adult (≥16 years) HIV-positive persons receiving care between 2004 and 2011 at one of four ART programs in South Africa. These programs collaborate with the International Epidemiologic Databases to Evaluate AIDS Southern Africa (www.iedea-sa.org) and collected data for AIDS-defining cancers but not for other cancers. To improve cancer ascertainment we probabilistically linked patient records (using first name, surname, age, and gender) from two HIV cohorts with the cancer records of the South African National Cancer Registry. We calculated incidence rates per 100,000 person-years after starting ART for the AIDS-defining cancers, i.e. Kaposi sarcoma (KS), invasive cervical cancer (ICC) and non-Hodgkin lymphoma (NHL). We compared incidence rates before and after inclusion of record linkage identified cancer cases using the attributable fraction of cancers identified with 95% confidence intervals (CI). ResultsA total of 49,207 adults starting ART in South Africa were included. 65% of patients were female, median age at starting ART was 35 years (interquartile range 30-41 years). We identified a total of 471 incident cancer cases. With record linkage the incidence increased from 81 to 292 for KS, from 1 to 119 for NHL and 12 to 497 for ICC per 100,000 person-years. The attributable fraction of cancers identified was 72% (95% CI 63-79%) for KS, 98% (95% CI 94-99%) for NHL and 98% (95% CI 95-99%) for ICC. ConclusionAscertainment of cancer in HIV program data in African settings is incomplete. This case study has shown that probabilistic record linkage to cancer registries is both feasible and essential for cancer ascertainment in HIV cohorts in South Africa.
