1.Contemporary clinical trials in uterine corpus malignancies.
Korean Journal of Obstetrics and Gynecology 2007;50(10):1299-1307
Uterine cancer is the most common gynecologic malignancy in Western countries. In Korea, its incidence has been rising, and the increased incidence is associated with a rising death rate. The first two decades of endometrial cancer study by the GOG began with a prospective, surgicopathologic staging trial that was the cornerstone for development of all subsequent trials. The therapeutic strategies were tailored to disease extent - low risk, intermediate risk, and high risk groups of patients. There were great advances in the area of chemotherapeutic agents through a number of extensive phase II trials. New trials of these agents have been opened for the patients with advanced or recurrent uterine cancers.

OBJECTIVETo evaluate the trend of cervical cancer incidence and mortality rates during 1989-2008 in Chinese women, so as to inform the development of relevant policies and strategies in China.
METHODSThe incidence and mortality rates of cervical cancer during 1989-2008 in urban and rural areas were calculated based on the data from the National Cancer Registry Database. Age-standardized rates were calculated using the Chinese population of 1982 and World Segi's population of 1985. Joinpoint regression analysis was performed to obtain annual percentage changes (APC) so as to assess the trend of incidence and mortality rates over the period from 1989 to 2008.
RESULTSThe crude incidence rate of cervical cancer in Chinese women increased from 3.06/10(5) in 1989-1990 to 11.87/10(5) in 2007-2008 (from 4.96/10(5) to 11.98/10(5) in urban registration areas and from 2.39/10(5) to 11.77/10(5) in rural registration areas).The crude mortality rate slightly increased from 2.19/10(5) in 1989-1990 to 3.20/10(5) in 2007-2008 (from 3.21/10(5) to 2.56/10(5) in urban registration areas and from 1.82/10(5) to 3.75/10(5) in rural registration areas). Generally, the upward trends of crude incidence rates were shown over the year 1989-2008, with an APC of 14.4% after 1997 in urban areas and 22.5% after 1999 in rural areas.After age standardization of world population, the APC of incidence rates in recent decade in urban areas remained stable, and the one in rural areas slightly decreased.Although the overall crude and world age-standardized mortality rates had no significant changes during 1989-2008, the crude mortality rates increased by 8.1% annually after 1999.The upward trends were also shown for crude and world age-standardized mortality rates in urban areas after 2001 with an APC of 7.3%.The crude mortality rates in rural areas increased by 3.9% annually during 1989-2008, but no significant change was found after age standardization.
CONCLUSIONSOver the last decade, the cervical cancer incidence and mortality rates ascended by year in China. It is particularly urgent to establish a comprehensive prevention and control system that combines cervical cancer screening and human papillomavirus vaccination, so as to reduce the burden of cervical cancer in Chinese women.

Objective: To analyze the data of malignant tumor mortality and change in disease burden in Hebei province from 1973 to 2013. Methods: Cancer mortality rate, age-standardized mortality rate and the years of life lost due to premature mortality (YLLs) were calculated by using the data from three rounds of all death causes survey and database of cancer registry in Hebei during 1973-2013. Results: From 1973 to 2013, a linear upward of malignant tumor mortality was observed, with a 51.57% increase. The mortality rate during 1973-1975 was 98.52/100 000 and it was 149.33/100 000 during 2011-2013. During 1973-1975, the YLLs was 17.0/1 000 in males and 12.8/1 000 in females. While during 2011-2013, the YLLs was 23.2/1 000 in males and 15.9/1 000 in females. During 1973-1975, esophagus cancer, stomach cancer and liver cancer were top three leading causes of deaths. During 2011-2013, lung cancer, stomach cancer and liver cancer were main leading causes of deaths. During the past 40 years, the deaths of esophagus cancer and cervix cancer decreased dramatically, but the deaths of lung cancer and breast cancer increased sharply. Conclusions: The disease burden caused by malignant tumor is becoming more serious in Hebei. It is necessary to strengthen the primary prevention and screening of malignant tumor.

OBJECTIVE: To evaluate uterine and ovarian cancer mortality trends in East Asian countries. METHODS: For three Asian countries and one region (Japan, Korea, Singapore, and Hong Kong), we extracted number of deaths for each year from the World Health Organization (WHO) mortality database, focusing on women > or =20 years old. The WHO population data were used to estimate person-years at risk for women. The annual age-standardized, truncated rates were evaluated for four age groups. We also compared age-specific mortality rates during three calendar periods (1979 to 1988, 1989 to 1998, and 1999 to 2010). Joinpoint regression was used to determine secular trends in mortality. To obtain cervical and uterine corpus cancer mortality rates in Korea, we re-allocated the cases with uterine cancer of unspecified subsite according to the proportion in the National Cancer Incidence Databases. RESULTS: Overall, uterine cancer mortality has decreased in each of the Asian regions. In Korea, corrected cervical cancer mortality has declined since 1993, at an annual percentage change (APC) of -4.8% (95% confidence interval [CI], -5.3 to -4.4). On the other hand, corrected uterine corpus cancer mortality has abruptly increased since 1995 (APC, 6.7; 95% CI, 5.4 to 8.0). Ovarian cancer mortality was stable, except in Korea, where mortality rates steadily increased at an APC of 6.2% (95% CI, 3.4 to 9.0) during 1995 to 2000, and subsequently stabilized. CONCLUSION: Although uterine cancer mortality rates are declining in East Asia, additional effort is warranted to reduce the burden of gynecologic cancer in the future, through the implementation of early detection programs and the use of optimal therapeutic strategies.

We evaluated the influence of socioeconomic factors on female cancer mortality using death data from the Cause of Death Statistics and the Korean Population and Housing Census databases collected in 2001, 2006, and 2011. We estimated Relative Index of Inequality (RII) of female cancer mortality using Poisson regression analysis. RII greater than 1 indicates increased mortality risk for women at the lowest educational level compared with women at the highest educational level. The RII for cervical cancer mortality was persistently greater than 1 for the entire study period, with a gradual increase over time. Subgroup analysis stratified by age (25-44 and 45-64 yr) revealed that younger women had increased RIIs of mortality due to cervical cancer and ovarian cancer during the entire study period. Older women had higher RII only for cervical cancer mortality, but the value was much lower than that for younger women. The RII for breast cancer mortality was greater than 1 for younger women since 2006. In conclusion, socioeconomic inequality in female cancer mortality has persisted for the last decade in Korea, which was most evident for cervical cancer, and for younger women.

BACKGROUND: There have been growing interests in harmful effects of dust particles on human health. It has been reported that dust particles negatively affected respiratory and cardiovascular systems. Relationship of dust particles and lung cancer incidence was also investigated. However, there is a lack of studies regarding the relationship between dust particles and cancers except for lung cancer. Therefore, this study aimed to determine the relationship of dust particle concentration and cancer mortality in Korea. METHODS: Average concentration of coarse dust particles (particulate matter 10, PM₁₀) of 2008-2014 were obtained from AirKorea website and cancer mortality was found in Statistics Korea for 2008-2014. Correlation analyses using PM₁₀ and cancer mortality were performed. Age-adjusted death rate (AADR) was used for correlation analysis because a number of death and mortality rate do not reflect population and age of death. Regional annual PM₁₀ was matched with AADR of identical area. Correlation between two variables was presented in scatter plots and Pearson's correlation analysis was performed. RESULTS: PM₁₀ concentration was positively correlated with AADR of malignant neoplasm, lung cancer, stomach cancer, colon cancer, uterus cancer, and leukemia. PM₁₀ concentration was significantly correlated with AADR of malignant neoplasm (r=0.247, P=0.009), lung cancer (r=0.277, P=0.003), stomach cancer (r=0.434, P=0.000), colon cancer (r=0.377, P=0.000), and uterus cancer (r=0.226, P=0.017). CONCLUSION: This study suggested that cancer patients or high-risk group for cancer should pay attention to PM₁₀ concentration. Large-scale studies should investigate the relationship of PM10 concentration and cancer incidence including cancer mortality to extend understanding of this cross-section study.

8.Prophylactic Vaccine for Cervical Carcinoma.
Journal of the Korean Medical Association 2007;50(2):151-158
Cervical cancer is the second most common malignant neoplasm affecting women worldwide, with a high rate of mortality throughout the world. Since epidemiologic, biologic, and genetic data have identified a consistent association of human papillomavirus (HPV) infection with cervical cancer development, many researchers have worked on the development of HPV vaccine to establish an efficient program to manage cervical carcinoma in developed countries. Therefore, the aims of this study are to overview the current status of vaccine and to systematically analyze the development process of HPV vaccine through a review of the literature. The basic and clinical data on HPV vaccine inside and outside the country were collected by Medline searching. Recent lines of research on the safety and efficacy of candidate prophylactic vaccines against HPV have shown very promising results with nearly 100% efficacy in preventing persistent infections and the development of cervical precancerous lesions. The variable routes of vaccine administration have been tried-nasal and oral vaccination, as well as parental injection. Recently, clinical trials involving a large population and multi-institutions are ongoing, and also clinical trials are expected in Korea. Although the results of previous HPV vaccine studies are invariably encouraging, several drawbacks need to be addressed. Because the genotype of HPV is regionally different, Korean-specific vaccine needs to be developed, and there are many unsolved problems regarding, for example, the booster injection, optimal timing of vaccination, and vaccination in men.

9.Research on Uterine Cervical Cancer in Korea: Current Status and Perspectives.
Journal of the Korean Medical Association 2007;50(9):807-814
In Korea, cervical cancer is the fifth most common female cancer and the eighth most common cause of female cancer deaths. It is the most frequently diagnosed gynecologic cancer. Over the past decades, a marked reduction in the incidence and mortality of this malignancy has been documented. This has been largely attributed to widespread screening using papanicolaou smear, the early detection and treatment of preivasive lesions, and development of an effective treatment modality for invasive cervical cancer. The recently developed human papilomavirus vaccine is expected to further reduce the incidence and mortality of this malignancy markedly. Epidemiologic, biologic, and clinical research on cervical cancer is carried out worldwide to introduce human papillomavirus test and vaccine and to develop effective treatment for invasive cancer. At this point of time, the author reviewed the present status of research on cervical cancer and proposed future studies required to reduce the incidence and mortality of this malignancy in Korea.

OBJECTIVE: Few data exist regarding adjuvant hysterectomy (AH) in locally advanced cervical cancer (LACC) patients treated with chemoradiotherapy. We investigated the effect of AH on prognosis in LACC patients, through meta-analysis. METHODS: EMBASE and MEDLINE databases and the Cochrane Library were searched for published studies comparing LACC patients who received AH after chemoradiotherapy with those who did not, through April 2016. Endpoints were mortality and recurrence rates. For pooled estimates of the effect of AH on mortality/recurrence, random- or fixed-effects meta-analytical models were used. RESULTS: Two randomized trials and six observational studies (AH following chemoradiotherapy, 630 patients; chemoradiotherapy, 585 patients) met our search criteria. Fixed-effects model-based meta-analysis indicated no significant difference in mortality between the groups (odds ratio [OR]=1.01; 95% confidence interval [CI]=0.58–1.78; p=0.968) with low cross-study heterogeneity (p=0.73 and I2=0.0). This pattern was observed in subgroup analysis for study design, radiation type, response after chemoradiotherapy, and hysterectomy type. The pooled OR for AH and recurrence was 0.59 (95% CI=0.44–0.79; p < 0.05) with low cross-study heterogeneity (p=0.29 and I2=17.8), favoring the AH group. However, this pattern was not observed in the subgroup analysis for the randomized trials. There was no evidence of publication bias. CONCLUSION: In this meta-analysis, AH following chemoradiotherapy did not improve survival in patients with LACC, although it seemed to reduce the risk of recurrence. Concerning the significant morbidity of AH after chemoradiotherapy, routine use of AH should be avoided.
