2002 annual report of the Korea Central Cancer Registry: based on registered data from 139 hospitals.

Abstract: PURPOSE To estimate the number of cancer cases during 2002 in Korea through a nationwide hospital based cancer registration by the Korea Central Cancer Registry (KCCR). MATERIALS AND METHODS One hundred and thirty nine hospitals participated in the KCCR program in 2002. Cancer cases were coded and classified according to the International Classification of Diseases for Oncology 2(nd) edition (ICD-O-2). The software program "IARC Check" was used to evaluate the quality of registered cancer cases. Of the 122,770 malignancies registered, 11,732 (9.6%) duplicated malignancies were excluded. Among the remaining 102,677 malignancies, 3,652 (3.6%) cases with carcinoma in situ (Morphology code/2) were separated. Finally, 99,025 malignancies were analyzed. RESULTS Of the total of 99,025 malignancies, 55,398 (55.9%) cases were males and 43,627 (44.1%) were females. More than one third of cases were from the elderly (65 years old and more). The six leading primary cancer sites in the order of their relative frequency, were stomach (24.0%), followed by the lung (16.0%), the liver (15.4%), the colorectum (11.6%), the bladder (3.2%), and the prostate (3.0%) among males. In females, the breast (16.8%) was the common cancer site, followed by the stomach (15.3%), the colorectum (10.7%), the thyroid gland (9.5%), the cervix uteri (9.1%), and the lung (6.6%). CONCLUSION With the continued increase in cancer cases especially prostate cancer among males and thyroid cancer among females, the total number of registered cancer cases in Korea continues to rapidly increase.

Hepatitis B and C Virus, Clonorchis sinensis for the Risk of Liver Cancer: A Case-Control Study in Pusan, Korea

Abstract: Background. Liver cancer mortality in Korea is the highest in the world. Hepatitis B and C viruses (HBV, HCV) are known to be the major risk factors of hepatocellular carcinoma (HCC). Cholangiocarcinoma (CLG) accounts for more than 20% of liver cancer in the Pusan area. In Korea, the different roles of known risk factors in the development of HCC or CLG have not been adequately evaluated. Methods. Case-control studies involved 203 incident HCC cases, 406 controls matched to the HCC cases for age (± 4 years) and sex, and 41 CLG cases (the HCC controls were used). They were carried out from August 1990 to August 1993. Results. Relative risk (RR) of HBsAg (87.4 ; 95% confidence interval [CI] : 22.2-344.3) and RR of anti-HCV positivity (30.3 ; 95% CI : 6.1-150.6) were significant for the risk of HCC after adjustment for potentially confounding factors. In contrast, RR of Clonorchis sinensis in stool (2.7 ; 95% CI : 1.1-6.3) and RR of heavy drinking (4.6 ; 95% CI : 1.4-15.2) were significant for the risk of CLG. Transfusion history, acupuncture history, and cigarette smoking were not associated with the risk of HCC or CLG. Conclusions. Strong evidence indicated that both HBV and HCV infection were independent risk factors for HCC. In contrast, C. sinensis in stools and heavy drinking were associated with the risk of CLG in Korea.

Prevalence and determinants of genital infection with Papillomavirus, in female and male university students in Busan. South Korea

Abstract: Background. Little is known about the prevalence of human papillomavirus (HPV) infection in young adults in Asia. Methods. We invited female and male students in Busan, South Korea, to participate in a survey that included, for females, self-collection of vaginal cells and, for males, physician-performed collection of exfoliated genital cells. The prevalences of 25 HPV types were evaluated, by a polymerase chain reaction-based assay, in 672 female students (median age, 19 years) and in 381 male students (median age, 22 years). Results. HPV DNA was detected more frequently in female students (15.2%) than in male students (8.7%); in both sexes, high-risk HPV types were predominant. Among sexually active students, HPV prevalence was 38.8% in females and 10.6% in males. In female students, currently smoking cigarettes and having multiple lifetime sex partners were the strongest risk factors for HPV infection; in male students, associations between HPV prevalence and sexual habits were similar to those in female students but never attained statistical significance. Conclusions. Young women in South Korea start having penetrative sexual intercourse relatively late (median age, 18 years), but, once they begin, HPV prevalence quickly rises to levels comparable with those found in university students in the United States and in northern Europe. The high rate of participation in our study suggests that trials of new vaccines against HPV may be feasible among university students in South Korea.

The Cancer-Preventive Potential of Panax ginseng - A Review of Human and Experimental Evidence -

Abstract: Objective : We have reviewed the potential cancer preventive and other relevant properties of Panax ginseng C A Meyer, which has been traditionally used as a natural tonic in oriental countries Data identification and study selection: Publications on Panax ginseng and its relation to cancer were obtained from the Medline database (1983-2000) and by checking reference lists to find earlier reports The reports cover experimental models and human studies on cancer-preventive activity, carcinogenicity and other beneficial or adverse effects In addition, possible mechanisms of chemoprevention by ginseng were also considered Results : Published results from a cohort and two case-control studies in Korea suggest that the intake of ginseng may reduce the risk of several types of cancer When ginseng was tested in animal models, a reduction in cancer incidence and multiplicity at various sites was noted Panax ginseng and its chemical constituents have been tested for their inhibiting effect on putative carcinogenesis mechanisms (eg, cell proliferation and apoptosis, immunosurveillance, angiogenesis); in most experiments inhibitory effects were found Conclusion : While Panax ginseng C A Meyer has shown cancer preventive effects both in experimental models and in epidemiological studies, the evidence is currently not conclusive as to its cancer-preventive activity in humans The available evidence warrants further research into the possible role of ginseng in the prevention of human cancer and carcinogenesis

Sexual behavior, condom use, and human papillomavirus: Pooled analysis of the IARC human papillomavirus prevalence surveys

Abstract: Human papillomavirus (HPV) is a sexually transmitted infection but it is unclear whether differences in transmission efficacy exist between individual HPV types. Information on sexual behavior was collected from 11 areas in four continents among population-based, age-stratified random samples of women of ages > or = 15 years. HPV testing was done using PCR-based enzyme immunoassay. Unconditional logistic regression was used to estimate odds ratios (OR) of being HPV positive and corresponding 95% confidence intervals (95% CI). Variables were analyzed categorically. When more than two groups were compared, floating confidence intervals were estimated by treating ORs as floating absolute risks. A total of 11,337 women (mean age, 41.9 years) were available. We confirmed that lifetime number of sexual partners is associated with HPV positivity (OR for > or = 2 versus 1, 1.86; 95% CI, 1.63-2.11) but the association was not a linear one for HPV18, 31, and 33 (i.e., no clear increase for > or = 3 versus 2 sexual partners). Women who had multiple-type infection and high-risk HPV type infection reported a statistically nonsignificant higher number of sexual partners than women who had single-type and low-risk type infections, respectively. Early age at sexual debut was not significantly related to HPV positivity. Husband's extramarital sexual relationships were associated with an OR of 1.45 (95% CI, 1.24-1.70) for HPV positivity in their wives after adjustment for age and lifetime number of women's sexual partners. We did not observe a significant association with condom use. Our study showed an effect of both women's and their husbands' sexual behavior on HPV positivity. Furthermore, it suggests some differences in the pattern of the association between sexual behavior and different HPV types.

Global cancer statistics

Abstract: The global burden of cancer continues to increase largely because of the aging and growth of the world population alongside an increasing adoption of cancer-causing behaviors, particularly smoking, in economically developing countries. Based on the GLOBOCAN 2008 estimates, about 12.7 million cancer cases and 7.6 million cancer deaths are estimated to have occurred in 2008; of these, 56% of the cases and 64% of the deaths occurred in the economically developing world. Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death among females, accounting for 23% of the total cancer cases and 14% of the cancer deaths. Lung cancer is the leading cancer site in males, comprising 17% of the total new cancer cases and 23% of the total cancer deaths. Breast cancer is now also the leading cause of cancer death among females in economically developing countries, a shift from the previous decade during which the most common cause of cancer death was cervical cancer. Further, the mortality burden for lung cancer among females in developing countries is as high as the burden for cervical cancer, with each accounting for 11% of the total female cancer deaths. Although overall cancer incidence rates in the developing world are half those seen in the developed world in both sexes, the overall cancer mortality rates are generally similar. Cancer survival tends to be poorer in developing countries, most likely because of a combination of a late stage at diagnosis and limited access to timely and standard treatment. A substantial proportion of the worldwide burden of cancer could be prevented through the application of existing cancer control knowledge and by implementing programs for tobacco control, vaccination (for liver and cervical cancers), and early detection and treatment, as well as public health campaigns promoting physical activity and a healthier dietary intake. Clinicians, public health professionals, and policy makers can play an active role in accelerating the application of such interventions globally.

Cancer incidence and mortality worldwide: sources, methods and major patterns in GLOBOCAN 2012.

Abstract: Estimates of the worldwide incidence and mortality from 27 major cancers and for all cancers combined for 2012 are now available in the GLOBOCAN series of the International Agency for Research on Cancer. We review the sources and methods used in compiling the national cancer incidence and mortality estimates, and briefly describe the key results by cancer site and in 20 large “areas” of the world. Overall, there were 14.1 million new cases and 8.2 million deaths in 2012. The most commonly diagnosed cancers were lung (1.82 million), breast (1.67 million), and colorectal (1.36 million); the most common causes of cancer death were lung cancer (1.6 million deaths), liver cancer (745,000 deaths), and stomach cancer (723,000 deaths).

Cancer statistics in China, 2015

Abstract: With increasing incidence and mortality, cancer is the leading cause of death in China and is a major public health problem. Because of China's massive population (1.37 billion), previous national incidence and mortality estimates have been limited to small samples of the population using data from the 1990s or based on a specific year. With high-quality data from an additional number of population-based registries now available through the National Central Cancer Registry of China, the authors analyzed data from 72 local, population-based cancer registries (2009-2011), representing 6.5% of the population, to estimate the number of new cases and cancer deaths for 2015. Data from 22 registries were used for trend analyses (2000-2011). The results indicated that an estimated 4292,000 new cancer cases and 2814,000 cancer deaths would occur in China in 2015, with lung cancer being the most common incident cancer and the leading cause of cancer death. Stomach, esophageal, and liver cancers were also commonly diagnosed and were identified as leading causes of cancer death. Residents of rural areas had significantly higher age-standardized (Segi population) incidence and mortality rates for all cancers combined than urban residents (213.6 per 100,000 vs 191.5 per 100,000 for incidence; 149.0 per 100,000 vs 109.5 per 100,000 for mortality, respectively). For all cancers combined, the incidence rates were stable during 2000 through 2011 for males (+0.2% per year; P = .1), whereas they increased significantly (+2.2% per year; P < .05) among females. In contrast, the mortality rates since 2006 have decreased significantly for both males (-1.4% per year; P < .05) and females (-1.1% per year; P < .05). Many of the estimated cancer cases and deaths can be prevented through reducing the prevalence of risk factors, while increasing the effectiveness of clinical care delivery, particularly for those living in rural areas and in disadvantaged populations.
