The incidence and survival of cervical, ovarian, and endometrial cancer in Korea, 1999-2017: Korea Central Cancer Registry.

ABSTRACT:

Objective

The three major gynecologic cancers are cervical, endometrial, and ovarian cancer. This study aimed to describe the 19-year trends and survival rates in cervical, endometrial, and ovarian cancer in a Korean female population.

Methods

We searched the Korea Central Cancer Registry to identify patients with gynecologic cancer between 1999 and 2017. Age-standardized rates and annual percent changes were calculated. The relative survival rate (RSR) was reported by histology, age, and stage for each gynecological cancer.

Results

The total number of cervical, endometrial, primary peritoneal, ovarian epithelial, fallopian tube (POFT) cancer was 134,863, with the number of cases increasing every year: 6,077 in 1999 to 8,011 in 2017. The incidence of cervical cancer has decreased; however, that of POFT and endometrial cancer has increased. The 5-year RSR of cervical, POFT, and endometrial cancer was reported to be 80.8%, 61.4%, and 88.1%, respectively. In the case of cervical cancer, squamous cell carcinoma showed better survival than other histology (82.8% vs. 73.5%). Furthermore, in the case of endometrial cancer, endometrioid histology had substantially better 5-year RSR than the others (93.2% vs. 76.5%). Contrastingly, in the case of ovarian cancer, serous carcinoma had worse 5-year RSR than other types of histology.

Conclusion

The incidence rates for gynecologic cancers increased from 2005 to 2017, with an annual increase of 2.76 per year until 2017. Endometrial cancer had the highest RSR, while ovarian cancer had the lowest. Active cancer screening and the introduction of effective treatments might have contributed to the improved RSRs of gynecologic cancers.

Incidence of cervical, endometrial, and ovarian cancer in Korea during 1999-2015.

Project description:OBJECTIVE:To investigate the incidence and trends of cervical (C53), endometrial (C54.1), and ovarian cancer (C56) among Korean females between 1999 and 2015. METHODS:The incidence of the three major gynecological cancers between 1999 and 2015 was analyzed based on the data from the Korea Central Cancer Registry. The age-standardized rates (ASRs) and the annual percent changes (APCs) for each site were calculated. RESULTS:The absolute incidence rates of the three major gynecological cancers increased from 6,394 in 1999 to 8,288 in 2015. ASR for gynecologic cancer decreased from 23.7 per 100,000 in 1999 to 21.1 in 2015. This was mainly due to a definitive decrease in the incidence of cervical cancer, which recorded an APC of -3.7%. The trends of APC for gynecologic cancer were variable, being -1.36% between 1999 and 2006 and -0.11% between 2006 and 2015. A definitive but variable increase was noted for endometrial cancer, and the APC for this cancer was 7.4% between 1999 and 2009 and 3.5% between 2009 and 2015. The incidence of ovarian cancer gradually increased, with an APC of 1.8% between 1999 and 2015. CONCLUSION:Overall, ASRs and APCs for the three major gynecological cancers are decreasing, with a recent reduction in the width of the change. However, there has been a progressive increase in the incidence of endometrial and ovarian cancers.

Incidence, mortality, and survival of liver cancer using Korea central cancer registry database: 1999-2019.

Project description:Backgrounds/aimsHistorically, incidence and survival analysis and annual traits for primary liver cancer (LC) has not been investigated in a population-based study in Korea. The purpose of the current study is to determine incidence, survival rate of patients with primary LC in Korea.MethodsWe conducted a retrospective cohort study using Korea Central Cancer Registry based on the Korea National Cancer Incidence Database. Statistical analysis including crude rate and age-standadized rate (ASR) of incidence and mortality was performed for LC patients registered with C22 code in International Classification of Diseases, tenth revision from 1999 to 2019. Subgroup analysis was performed for hepatocellular carcinoma (HCC, C22.0) and intrahepatic cholangiocarcinoma (IHCC, C22.1).ResultsThe crude incidence rate of HCC (21.0 to 22.8 per 100,000) and IHCC (2.3 to 5.6 per 100,000) increased in the observed period from 1999 to 2019. The ASR decreased in HCC (20.7 to 11.9 per 100,000) but remained unchanged in IHCC (2.4 to 2.7 per 100,000). The proportion of HCC patients diagnosed in early stages (localized or regional Surveillance, Epidemiology, and End Results or SEER stage) increased significantly over time. As expected, 5-yeat survival rate of HCC was greatly improved, reaching 42.4% in the period between 2013 and 2019. This trait was more prominent in localized SEER stage. On the other hand, the proportion of IHCC patients diagnosed in localized stage remained unchanged (22.9% between 2013 and 2019), although ASR and 5-year survival rate showed minor improvements.ConclusionsA great improvement in survival rate was observed in patients with newly diagnosed HCCs. It was estimated to be due to an increase in early detection rate. On the contrary, detection rate of an early IHCC was stagnant with a minor improvement in prognosis.

Incidence and treatment outcomes of uterine cervical cancer in Korea 1999-2018 from the national cancer registry.

Project description:ObjectiveTo describe the incidence and survival outcomes of uterine cervical cancer during 1999-2018.MethodsPatients who were diagnosed with cervical cancer during 1999-2018 were identified in the Korea Central Cancer Registry. Age-standardized incidence rates (ASRs) and annual percent changes (APCs) were calculated. Survival rates by histology, year of diagnosis (1999-2008 vs. 2009-2018), stage, and age at diagnosis were analyzed.ResultsThe absolute incidence of cervical cancer decreased over 20 years from 4,488 in 1999 to 3,500 in 2018, with an APC of -3.42% (p<0.0001). While ASR of squamous cell carcinoma (SCCA) more than halved from 13.27 per 100,000 in 1999 to 6.16 in 2018 (APC, -4.04%), adenocarcinoma continued to rise (ASR, 1.30 per 100,000 to 1.92; APC, 1.52%; p<0.0001). Patients with adenocarcinoma were younger than those with SCCA (mean, 49.9±12.7 vs. 52.9 ±14.6 years; p<0.0001). Five-year survival rate of cervical cancer patients overall was 78.0%. Adenocarcinoma had poorer survival than SCCA (5-year survival rate, 76.8% vs. 79.8%; p<0.0001). There was no survival difference between patients who were diagnosed between 1999-2008 and 2009-2018. Earlier-stage disease had better survival (5-year survival rate for localized, regional, and distant disease, 90.0% vs. 69.9% vs. 26.5%; p<0.0001). Younger patients aged <50 years had better survival than those aged ≥50 years (87.1% vs. 69.8%; p<0.0001).ConclusionThe incidence of SCCA of the uterine cervix declined while adenocarcinoma continued to increase slowly but significantly from 1999 to 2018 in Korea. Adenocarcinoma was diagnosed at a younger age, but had poorer survival outcome than SCCA.

Incidence, mortality and survival of gallbladder, extrahepatic bile duct, and pancreatic cancer using Korea central cancer registry database: 1999-2019.

Project description:Backgrounds/aimsIn Korea, pancreatic cancer and "gallbladder and extrahepatic bile duct cancer" were ranked the 8th and 9th most frequent cancers in 2019 and the 4th and 6th most common causes of cancer deaths in 2020, respectively.MethodsThis review provides national cancer statistics and secular trends of 207,521 patients with gallbladder (n = 44,178), extrahepatic bile duct (n = 61,856), and pancreatic cancer (n = 101,487) between 1999 and 2019 in Korea.ResultsThe crude incidence rate in both sexes increased in the gallbladder (2.8 to 5.4 per 100,000), extrahepatic bile duct (3.6 to 9.0), and pancreatic cancer (5.5 to 15.8). The age-standardized incidence rate in both sexes significantly increased in the extrahepatic bile duct (3.7 to 4.1) and pancreatic (5.6 to 7.6) cancers but decreased in gallbladder cancer (2.9 to 2.4). The overall 5-year relative survival rate increased in the gallbladder (21.8% to 30.6%), extrahepatic bile duct (23.1% to 27.5%), and pancreatic (8.5% to 13.3%) cancers. Between 2006 and 2019, the proportion of localized or regional stages remained stable. The proportion of surgical treatment within the first 4 months after diagnosis was relatively higher in the gallbladder (42.2%) and extrahepatic bile duct (45.9%) cancers than in pancreatic cancer (22.2%).ConclusionsThe crude incidence and mortality rates of the gallbladder, extrahepatic bile duct, and pancreatic cancer are steadily increasing in Korea, and the prognosis remains poor. Early detection, active application of surgical treatment, and minimization of the proportion of untreated patients are required to improve the survival rates of these cancers.

Trends in incidence and survival of esophageal cancer in Korea: Analysis of the Korea Central Cancer Registry Database.

Project description:Background and aimThe diagnostic and therapeutic modalities of esophageal cancer have recently improved in Asia, and its prognosis is expected to change. This study provides a population-based report on the epidemiology of esophageal cancer in Korea.MethodsCancer incidence data from 1999 to 2013 were obtained from the Korea Central Cancer Registry, covering the entire population. Age-standardized incidence rates and annual percent changes were calculated according to subsites and histological types. Five-year relative survival rates were estimated for cases diagnosed between 1993 and 2013. Relative excess rates were compared between patients diagnosed from 2009 to 2013 and 2006 to 2008.ResultsThe age-standardized incidence rates decreased from 8.8 per 100 000 populations in 1999 to 5.9 in 2013 with an annual percent change of -2.6% in men and -2.2% in women. The most common histological type was squamous cell carcinoma, accounting for 90.2% of all esophageal cancers in 2013, followed by adenocarcinomas (3.1%), and their incidences decreased. The proportion of localized and regional cancer tended to increase compared with that of distant cancer. Five-year relative survival of squamous cell carcinoma improved from 12.1% (1993-1995) to 34.6% (2009-2013). Relative excess rate was 0.72 (95% confidence interval 0.65-0.80) in localized stage and 0.88 (95% confidence interval, 0.82-0.95) in regional stage comparing patients diagnosed from 2009 to 2013 and 2006 to 2008.ConclusionsThe incidence of esophageal cancer has decreased in Korea for the past 15 years, and 5-year survival rates have improved significantly. These increases may be attributable to more effective detection of early-stage disease.

Incidence of Cervical, Ovarian and Uterine Cancer in Eritrea: Data from the National Health Laboratory, 2011-2017.

Project description:The main objective of this study was to investigate the incidence of cervical (C53), ovarian (C56) and uterine (C54-55) cancers in pathology department of the National Health Laboratory of Eritrea between 2011 and 2017. All tumour positive cases from cervix, ovary and uterus diagnosed between 2011 and 2017 were analyzed, based on the data from the pathology department available in National Health Laboratory. We summarized the results by using crude incidence rates (CIR) and age-standardized rates (ASRs). Annual percentage changes (APCs) for each site were calculated and compared according to ten-year age difference and year of occurrence. Between 2011 and 2017, 883 cases of cervical, ovarian and uterine tumours were reported in Eritrea. Malignant and benign tumours/entities comprising 269 and 614, respectively. The ASR for malignant tumours was highest in women aged between 60-69 (6.84 per 100 000). Total ASR for specific gynecological cancers (cervical, ovarian, uterine) was 19.32 per 100 000 females. The ASR for cervical cancer over the study period was 8.7 per 100 000. The ASR for ovarian and uterine cancers were 6.75 per 100 000 and 5.14 per 100 000, respectively. Over the study period, the incidence of these cancers was largely stable with no significant change in incidence rates recorded. In sum, the ASR for cervical cancer is relatively low compared to the rates reported in the region. Further, the ASR for ovarian and uterine cancers is nearly similar to the rates observed in this region. The study also provides ample evidence on the need for research targeted at uncovering the true burden of gynecological cancers in Eritrea. Potential solutions will require the establishment of high-quality population-based cancer registries (PBCRs) and long-term commitment to improvements in research platforms, training, screening, diagnosis, and the overall management of cancers in the country.

Breast Cancer Statistics in Korea in 2017: Data from a Breast Cancer Registry.

Project description:This article describes the breast cancer statistics in Korea, including the incidence, type of surgical procedure, stage, and molecular subtype, using the Korean Breast Cancer Society (KBCS) and Korea Central Cancer Registry data. There were a total of 26,534 new breast cancer diagnoses in 2017 in Korea, of which 4,139 were carcinoma in situ cases and 22,395 were invasive cancer cases. The age standardized rate of breast cancer was 75.3 per 100,000 women in 2017 (63.0 of invasive carcinoma and 12.3 of carcinoma in situ), and it has been steadily increasing across all age groups. Breast cancer occurred most commonly in the 40-49 age group. Compared to 2016, breast conserving surgery (BCS) has increased, and 67.4% of patients were treated with BCS in 2017. The proportions of stage 0 and stage I have continued to increase, accounting for 60.7%. The most common subtype of breast cancer was hormone receptor (HR) positive and human epidermal growth factor receptor-2 (HER2) negative type comprising 65.9% of the cases, whereas HR negative and HER2 positive type was the rarest comprising 10.2% of the cases. The 5-year relative survival rate of breast cancer patients had increased by 14.0% from 79.2% in 1993-1995 to 93.2% in 2013-2017. It is essential to actively enter breast cancer data into the KBCS registry to improve our understanding.

Spatial distribution and determinants of thyroid cancer incidence from 1999 to 2013 in Korea.

Project description:We evaluated the spatial variation in thyroid cancer incidence and its determinants in Korea considering its importance in cancer prevention and control. This study was based on the ecological design with cancer incidence data by administrative district from the National Cancer Center and regional characteristics generated from the Korea Community Health Survey Data. We identified spatial clusters of thyroid cancer incidences based on spatial scan statistics. Determinants of regional variation in thyroid cancer incidence were assessed using the Besag-York-Mollie model with integrated nested Laplace approximations. Spatial clusters for low and high thyroid cancer incidences were detected in the northeastern and southwestern regions, respectively. Regional variations in thyroid cancer incidence can be attributed to the prevalence of recipients of basic livelihood security (coefficient, - 1.59; 95% credible interval [CI], - 2.51 to - 0.67), high household income (coefficient, 0.53; 95% CI, 0.31 to 0.76), heavy smoking (coefficient, - 0.91; 95% CI, - 1.59 to - 0.23), thyroid dysfunction (coefficient, 3.24; 95% CI, 1.47 to 5.00), and thyroid cancer screening (coefficient, 0.38; 95% CI, 0.09 to 0.67). This study presented the spatial variations in thyroid cancer incidence, which can be explained by the prevalence of socioeconomic factors, thyroid cancer screening, thyroid dysfunction, and smoking.

Trends in Gastric Cancer Incidence According to the Clinicopathological Characteristics in Korea, 1999-2014.

Project description:PurposeThe aim of this study was to evaluate recent trends in gastric cancer incidence according to the age, sex, and tumor location in the Korean population.Materials and methodsUsing data from the Korea Central Cancer Registry between 1999 and 2014, gastric cancer incidence, annual percent changes, and male-to-female incidence rate ratios (IRRs) according to tumorlocationwere determined. The distribution of disease extent according to the tumor location and its changes between 2006 and 2014 were also analyzed.ResultsIncidence of gastric cancer was stable until 2011 and decreased between 2011 and 2014. The age-standardized incidence rate of gastric cancer was 43.6 (per 100,000) in 1999 and 35.8 in 2014. The proportion of cardia/fundus cancer remained stable (5.9% to 7.1%), and that of body cancer increased (35.3% to 43.2%). The male-to-female IRR decreased in most age groups, except for those in their 60s. In the distribution of disease extent, the proportion of localized disease increased, and regional and distant disease decreased in all tumor locations (53.9% to 66.0%, 31.4% to 22.5%, and 14.8% to 11.5%, respectively; p < 0.001). For histological type, the proportion of carcinoid tumor and non-epithelial tumor increased (0.3% to 1.0%, and 0.8% to 1.4%, respectively).ConclusionIn the 15 years from 1999 through 2014, age-standardized incidence of gastric cancer started to decrease from 2012, and the proportion of cardia/fundus cancer remained unchanged. The trend of increasing localized cancer was observed in all tumor locations.

Assessing Impact of HPV Vaccination on Cervical Cancer Incidence among Women Aged 15-29 Years in the United States, 1999-2017: An Ecologic Study.

Project description:BackgroundTo date, the impact of the human papillomavirus (HPV) vaccine on invasive cervical cancers in the United States has not been documented due, in part, to the time needed for cancer to develop and to recent changes to cervical cancer screening guidelines and recommendations, which complicate data interpretation.MethodsWe examined incidence rates of cervical squamous cell carcinoma (SCC) and adenocarcinoma (AC) among women aged 15-29 years diagnosed during 1999-2017 using population-based cancer registry data covering 97.8% of the U.S.PopulationTrends were stratified by age and histology. The annual percent change in cervical cancer incidence per year was calculated using joinpoint regression.ResultsDuring 1999-2017, SCC rates decreased 12.7% per year among women aged 15-20 years, 5.5% among women aged 21-24 years, and 2.3% among women aged 25-29 years. The declines in SCC rates were largest among women aged 15-20 years during 2010-2017, with a decrease of 22.5% per year. Overall, AC rates decreased 4.1% per year among women aged 15-20 years, 3.6% per year among women aged 21-24 years, and 1.6% per year among women aged 25-29 years. AC rates declined the most among women aged 15-20 years during 2006-2017, decreasing 9.4% per year.ConclusionsSince HPV vaccine introduction, both SCC and AC incidence rates declined among women aged 15-20 years, a group not typically screened for cervical cancer, which may suggest HPV vaccine impact.ImpactTimely vaccination and improved screening and follow-up among recommended age groups could result in further reductions in invasive cervical cancer.
