ABSTRACT
Objective:To investigate the incidence and mortality of lung cancer in the cancer registration areas of Shanxi Province in 2017.Methods:The cancer registration data reported by 12 tumor registration areas of Shanxi in 2017 were sorted out and stratified by urban and rural areas and gender. The number of incidence and death ,the crude incidence and mortality, the cumulative rate (0-74 years), age-specific incidence and mortality, Chinese population standardized rate and world population standardized rate were calculated. The incidence and mortality were standardized by the 2000 China census standard population composition and Segi's world standard population composition.Results:In 2017, there were 2 275 new cases and 1 736 deaths of lung cancer in the tumor registration area of Shanxi Province. The crude incidence rate of lung cancer was 46.72/100 000 (male 63.99/100 000, female 28.80/100 000, urban area 58.05/100 000, rural area 39.09/100 000), Chinese population standardized rate was 31.67/100 000, the world population standardized rate was 32.10/100 000, and the cumulative rate (0-74 years) was 3.87/100 000. The crude mortality rate was 35.65/100,000 (male 49.84/100,000, female 20.93/100,000, urban area 44.53/100,000, rural area 29.67/100 000), Chinese population standardized rate was 23.82/100 000, the world population standardized rate was 24.14/100 000, and the cumulative rate (0-74 years) was 2.69/100,000. Overall, the age-specific incidence and mortality of lung cancer in 2017 were at a low level in 0-44 years age group, and increased rapidly after 45 years age group, and reached a peak in 85 years age group. The incidence and mortality of lung cancer in males were higher than that in females. Although there were some differences in the incidence and mortality of patients with different ago range in urban and rural areas, the overall trend was similar.Conclusions:Lung cancer is the most common malignant tumor threatening the health of residents in Shanxi Province. Male, urban areas and middle-aged and elderly population are the focus of cancer prevention and control in Shanxi Province. Lung cancer prevention and control should be targeted carried out according to the differences between urban and rural areas and gender.
ABSTRACT
Objective To analyze the incidence, mortality and time trend of lung cancer in Heilongjiang Cancer Registries from 2013 to 2017. Methods We calculated the incidence (mortality) rate and age-standardized incidence (mortality) rate of lung cancer in Heilongjiang Cancer Registries from 2013 to 2017. Chinese population census in 2000 and World Segi's standard population were used for age-standardization. Annual percentage change (APC) was calculated using Joinpoint software. Results The incidence of lung cancer in Heilongjiang Cancer Registries from 2013 to 2017 was 63.44/105 and ASR China was 36.14/105. The incidence of lung cancer in males (78.08/105) was higher than that in females (49.04/105). The incidence of lung cancer in rural areas (65.54/105) was higher than that in urban areas (58.20/105). From 2013 to 2017, the mortality rate of lung cancer in Heilongjiang Cancer Registries was 57.02/105, and ASR China was 32.53/105. The mortality rate of lung cancer in males (69.92/105) was higher than that in females (44.40/105). The mortality rate of lung cancer in rural areas (60.68/105) was higher than that in urban areas (48.02/105). The incidence of lung cancer in the 55-year-old age group showed a downward trend (APC=-5.0%, t=-5.1, P < 0.05), and the mortality rate of lung cancer in the 70-year-old group showed a downward trend (APC=-4.9%, t=-5.0). Conclusion Heilongjiang Province is a high incidence area of lung cancer. The prevention and control of lung cancer should be further strengthened according to the epidemiological characteristics of lung cancer in this province.
ABSTRACT
Objective To understand the relative survival rate of cervical cancer patients in our hospital in the past 5 years, and to predict the relative survival rate in the next 5 years. The study can provide data information and scientific basis for cervical cancer prevention and treatment in Changde City. Methods According to the tumor registration database of our hospital, the 5-year relative survival rate of cervical cancer patients from 2010 to 2014 was evaluated by the cycle analysis method, and further stratified analysis was carried out according to the age of diagnosis and the township area. By establishing a generalized linear model based on the cycle analysis method, we predict the 5-year relative survival rate of patients in the future 2015-2019 period. Results From 2005 to 2019, the incidence of cervical cancer was the highest in the 45-54 age group, accounting for 40.54%. The incidence of cervical cancer was the lowest in the age group over 74, accounting for 2.72%. From 2010 to 2014, the overall 5-year relative survival rate of cervical cancer patients in our hospital was 92.73%, and the 5-year relative survival rates of patients 74 years old were 93.51%, 92.82%, 89.16%, 85.71% and 63.83%, respectively. The 5-year relative survival rates of urban and rural patients were 94.73% and 91.86%, respectively. It is predicted that the overall 5-year relative survival rate from 2015 to 2019 is 93.78%. Conclusion Compared with the previous second 5-year periods, the 5-year relative survival rate of patients in the future 2015-2019 will still show an upward trend, the age difference gradient will continue to be maintained, and the urban-rural difference will further decrease.
ABSTRACT
Objective@#To estimate the incidence, mortality and characteristics of cancer in Pearl River Delta Area of Guangdong Province between 2009-2013.@*Methods@#Based on five population-based cancer registration data from Guangzhou, Shenzhen, Zhongshan, Jiangmen and Sihui spanning from 2009 to 2013, along with those corresponding population data, the incidence and mortality rates were estimated by gender and age groups. Chinese standard population derived from the 2000 Population Census and Segi′s standard population were used for age-standardized incidence and mortality rates.@*Results@#Between 2009 and 2013, the crude cancer incidence rate was 262.50/100 000, 274.76/100 000 in male and 249.49/100 000 in female. After adjusting for Chinese and Segi′s standard population, the age-standardized incidence rates were 225.63/100 000 and 219.88/100 000, respectively. The crude mortality rate was 175.51/100 000, 222.92/100 000 in male and 127.46/100 000 in female, respectively. After adjusting for Chinese and Segi′s standard population, the age-standardized mortality rates were 116.02 /100 000 and 114.31/100 000, respectively. The incidence rates were at low levels in the population less than 40 years old, thereafter went up rapidly with age especially in male, and then reached the peak in the population aged 80 and above. As with incidence, the mortality rates kept at low levels in the population before their 50 s and then rose up steadily with age until peaking in the 85+ age group. The most common cancers were female breast cancer, lung cancer, colorectal cancer, liver cancer and nasopharyngeal cancer with descending incidence rate. Lung cancer, liver cancer, colorectal cancer, female breast cancer and nasopharyngeal cancer were the top five cancer-attributable causes of death.@*Conclusions@#Currently, Pearl River Delta Area were faced with huge cancer burden. Lung cancer, colorectal cancer, nasopharyngeal cancer, female breast cancer and male liver cancer are predominant cancers and more efforts should be made to fight against them.
ABSTRACT
Objective To describe and analyze the incidence and mortality of malignant tumors in Daoli District of Harbin from 2008 to 2012. Methods The tumor registration data of 2008—2012 reported by the Daoli District Cancer Registry was collect-ed. The crude incidence and mortality,China standardization rate,World standardization rate,cumulative rate and truncated incidence rate of major malignant tumors were calculated and trends of the incidence and mortality of malignant tumors in 5 years were analyzed. Results From 2008 to 2012,there were 10 893 cases of malignant tumors in Daoli District of Harbin,including 5879 males and 5 014 females. The incidence rate increased first and then stabilized. Incidence of malignancy,China standardization rate,world standardiza-tion rate,cumulative rate and truncated incidence rate in men were higher than those in women. The incidence rates were at a low level in the 0~25 age group,rising rapidly in the 25~80 age group,reaching a peak at the age of 80,and then beginning to decline. From 2008 to 2012,there were 6 801 cases of malignant tumor deaths in Daoli District of Harbin,including 4 069 males and 2 732 females. There was no significant change in mortality over five years. Malignancy mortality,China standardization rate,world standardization rate,cumulative rate and truncated incidence rate in men were higher than those in women. The mortality rates were at a low level in the 0~30 age group,rising rapidly in the 30~75 age group,reaching a peak at the age of 75,and then beginning to decline. The high-est incidence of malignant tumors in Daoli District from 2008 to 2012 was lung cancer,followed by liver cancer,colorectal cancer, stomach cancer and breast cancer. The highest mortality rate of malignant tumors was lung cancer,followed by liver cancer,colorectal cancer,stomach cancer and pancreatic cancer. Conclusion The incidence of malignant tumors in Daoli District of Harbin City in-creased first and then stabilized in 2008-2012,and there was no significant change in mortality. Lung cancer,digestive system malig-nant tumors,and female breast cancer are the main cancer types of malignant tumors incidence and death in Daoli District of Harbin.
ABSTRACT
Objective:To study the incidence rates of cancer in the urban area of Shijiazhuang city, China in 2012 based on the data of 2,374,827 registered residents. Methods: The incidence of diagnosed cancer cases in 2012 was obtained from the hospital reimbursement database of the medical insurance center of the city by retrieving the records on first-time reimbursement applications for the hospitalization of tumor patients from January 1 to December 31 in 2012. Population census data was obtained from the Population Department of the Shijiazhuang Public Security Bureau. The site-specific and sex-specific age-adjusted incidence rates were calculated. Results:The overall incidence rate, the age-adjusted rate of the Chinese population (ASRC), and the age-adjusted rate of the world population (ASRW) for both men and women were 237.53, 129.86, and 167.71 per 100,000 individuals, respectively. The incidence rate increased with age and peaked in the 75-79 years age groups of men and women at 1,729.42 and 867.35 per 100,000 individuals, respectively. The top ten most frequently diagnosed cancers in males were lung, stomach, colorectal, liver, esophagus, kidney, prostate, leukemia, bladder, as well as lymphoma, whereas those in females were the breast, lung, colorectal, stomach, cervical, uterine body, ovary, lymphoma, esophageal, and liver cancers. The incidence rate and ASRW of all cancers combined in men were 269.05 and 187.52 per 100,000 individuals, whereas those for women were 207.57 and 150.44 per 100 000 individuals, respectively. Compared with the average incidence rates of 31 Chinese cities in 2009, the ASRW of lung, stomach, and colorectal cancers in males from Shijiazhuang was nearly equal to the national level;however, the ASRW of breast cancer in females from Shijiazhuang was higher than the national level. When the incidence rates of Shijiazhuang in 2012 were compared with those of Beijing in 2009, the ASRW of stomach and esophageal cancers in men of Shijiazhuang was twice that of the same cancers in Beijing. However, the same parameters for the pancreatic and prostate cancers in men, as well as the thyroid and uterine body cancers in women of Beijing, were twice the values for Shijiazhuang. Conclusion: The ASRWs of the major types of cancer, such as the lung, stomach, colorectal, and breast cancers, in urban Shijiazhuang in 2012 were identical to those of the 31 Chinese cities in 2009. Compared with Beijing, the incidence rates of pancreatic, prostate, and thyroid cancers were significantly higher in Shijiazhuang, whereas those of esophageal and stomach cancers were significantly lower.
ABSTRACT
OBJECTIVES: An accurate estimation of cancer patients is the basis of epidemiological studies and health services. However in Korea, cancer patients visiting out-patient clinics are usually ruled out of such studies and so these studies are suspected of underestimating the cancer patient population. The purpose of this study is to construct a more complete, hospital-based cancer patient registry using multiple sources of medical information. METHODS: We constructed a cancer patient detection algorithm using records from various sources that were obtained from both the in-patients and out-patients seen at Asan Medical Center (AMC) for any reason. The medical data from the potentially incident cancer patients was reviewed four months after first being detected by the algorithm to determine whether these patients actually did or did not have cancer. RESULTS: Besides the traditional practice of reviewing the charts of in-patients upon their discharge, five more sources of information were added for this algorithm, i.e., pathology reports, the national severe disease registry, the reason for treatment, prescriptions of chemotherapeutic agents and radiation therapy reports. The constructed algorithm was observed to have a PPV of 87.04%. Compared to the results of traditional practice, 36.8% of registry failures were avoided using the AMC algorithm. CONCLUSIONS: To minimize loss in the cancer registry, various data sources should be utilized, and the AMC algorithm can be a successful model for this. Further research will be required in order to apply novel and innovative technology to the electronic medical records system in order to generate new signals from data that has not been previously used.

It was not until 1975 that cancer registration was initiated in Korea; voluntary registration of cancer patients of training hospitals throughout the country began under the auspices of the Korean Cancer Society(KCS). However, an official cancer registration, the Korea Central Cancer Registry(KCCR), began on July 1st, 1980. Forty-five training and two non-training hospitals throughout the country initiated registration of patients in whom neoplasms had been found. Data related to case information specified are to be sent to the KCCR at the National Medical Center(it moved at National Cancer Center in 2000). The initial cancer registration of KCS was merged to the KCCR in 1980. Although the KCCR covers most all the large training hospitals in Korea, it cannot provide incidence data. It is, however, the only of its kind in the world, being neither hospital nor population based. The first population based cancer registry(PBCR) was launched in a small county, Kangwha(it has around 80,000 inhabitants), by Yonsei University Medical College in 1983. All data were collected by active methods, and incidence statistics for 1986-1992 appeared in Vol VII of the CI5. Another PBCR, Seoul Cancer Registry(SCR), started in 1991. It was supported by a civilian foundation, the Korean Foundation for Cancer Research. The basic idea of case registration of SCR was the incorporation of KCCR data to PBCR, e. g. dual sources of case registration, i.e., from the KCCR and also including cases diagnosed in small hospitals and other medical facilities. Assessing completeness and validity of case registration of SCR, the program and methodology used by the SCR was later extended to other large cities and areas in Korea, and the PBCR in each area was established. Cancer incidence statistics of Seoul for 1993- 1997, Busan for 1996-1997, and Daegu for 1997-1998, as well as Kangwha for 1993-1997, appeared eventually in Vol VIII of the CI5. The Korean or 'pillar' model for a PBCR is a new one. The KCCR data file is a reliable basis, as a pillar, for a PBCR in each area. The main framework of the model for such a registry is the incorporation of a KCCR data file with data from additionally surveyed cases; the data related to cancer deaths, medical insurance claims, and visit-and abstract surveillance of non-KCCR medical facilities. Cancer registration has been adopted as a national cancer control program by Korean government in 2004 as the Anti-Cancer Act was enacted. Since then, some officers have tried to launch a nation-wide PBCR covering whole country. In the meantime, however, cancer registration was interrupted and discontinued for years due to the Privacy Protection Law, which was solved by an amendment of the Anti-Cancer Act in 2006. It would be premature to establish the nation-wide PBCR in Korea. Instead, continuous efforts to improve the completeness of registration of the KCCR, to progress existing PBCRs, and to expand PBCRs over other areas are still to be devoted. The nation-wide PBCR in Korea will be established eventually with summation of the PBCRs of the Korean model.
