RESUMEN
Objective@#The registration data of local cancer registries from 2008 to 2012 were collected by National Central Cancer Registry to estimate the incidence and mortality of female breast cancer in China.@*Methods@#Data from 135 registries were qualified and selected in the final analysis, and each registry at least has submitted data from 2010 to 2012. Cancer incidence and mortality analyses were stratified by area (urban/rural, eastern/middle/western areas) and age group. The age composition of standard population of Chinese census in 2000 and Segi′s population were used for age-standardized incidence and mortality in China and worldwide, respectively.@*Results@#A total of 135 registries were recruited in the analysis, covering 629 333 910 person-years (382 669 450 in urban and 246 664 460 in rural). About 13, 258 cases of female breast cancer were diagnosed and 32 205 cases were dead between 2008 and 2012. Female breast cancer incidence was 42.67/100, 000 and age-standardized rate calculated by worldwide standard population was 28.87/100, 000. The crude incidence of urban area was 51.85/100, 000, higher than 28.29/100, 000 of rural area, and the crude incidence of eastern area was 46.35/100, 000, higher than 36.38/100, 000 of middle area and 27.60/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age 55-59 (96.36/100, 000), and declined at age 60. The age-standardized incidence rate by Chinese standard population increased 30.56% from 2003 to 2012. The increase rate of rural area was 72.32%, faster than 23.48% of urban area. Female breast cancer mortality was 10.36/100, 000 and the age-standardized rate calculated by worldwide standard population was 6.61/100, 000. The crude mortality of urban area was 11.64/100, 000, higher than 8.36/100, 000 of rural area, and the crude mortality of eastern area was 10.81/100, 000, higher than 7.38/100, 000 of middle area and 9.90/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age above 85 (61.25/100, 000). Age-standardized incidence rate by Chinese standard population remained stable during the period of 2003-2012 (6.23%). The mortality rate mainly increased in rural area (54.94%), while decreased 2.32% in urban area over the 10 years.@*Conclusions@#Although the incidence and mortality of breast cancer in China are comparatively low worldwide, in China the incidence and mortality of female breast cancer have rose to the first and sixth place respectively among all the female cancers. The disease burden of breast cancer is very different between urban and rural area. Therefore, the targeted measure and strategy of control and prevention according to the area difference are needed.
RESUMEN
Organized,population-based colorectal cancer (CRC) screening has been implemented in various cities of China in order to control its rising threat.General practitioners (GPs) play a crucial role as central coordinators among potential screening participants,service providers and program organizers.However,rates of participation and adherence to CRC screening program remain low,whilst its program performance indicators are increasingly receiving more attention.In this review,we summarize the latest literature focusing on strategies to optimize the role of GPs in different stages of organized CRC screening programs,which could substantially enhance screening efficiency and cost-effectiveness of population-based screening programs.
RESUMEN
Background and purpose:Head and neck cancer is common worldwide. This article aimed to describe the patterns of incidence of head and neck cancer and their changes in Shanghai from 2003 to 2012, in order to provide reference for prevention programs, research and control strategies on cancer.Methods:The data of lip, oral cavity and pharynx cancer cases were collected by the Shanghai Cancer Registry. The distributions of Shanghai lip, oral cavity and pharynx cancer incidences from 2003 to 2012 were described. The patterns were described according to gender, age, basis of diagnosis, histological type, diagnostic stage in detail. We compared incidences of recent 5 years (from 2008 to 2012) with those of previous 5 years (from 2003 to 2007).Results:On average from 2003 to 2012, 1105 new cases of head and neck cancer were diagnosed in Shanghai each year, with 2.08% among the total cancer cases. The crude rate was 8.01 per 100000 and the age-standardized rate was 4.45 per 100000. Nasopharyngeal cancer was the major subtype of the head and neck cancer, with 50.81% among the total head and neck cases. The crude and age-standardized rates among males were higher than those among females. The histologically verified percentage was 85.77%. The squamous carcinoma was the major histological type, with 57.58% among the total cases. The age-stan-dardized rate of nasopharyngeal cancer was in decline.Conclusion:The incidence of head and neck cancer was low in Shanghai during the past 10 years. Male cases were more than female cases. The major histological type was squamous carcinoma. Half of new cases were nasopharyngeal cancer which appeared to affect patients at a relatively young age. Patients with nasopharyngeal cancer were diagnosed at relatively advanced stages.

Background and purpose:China is a high incidence area of liver cancer. The latest monitoring data in Shanghai show that liver cancer is one of the most common cancers with very high disease burden. This study aimed to describe and analyze the population-based survival rates of patients with liver cancer in Shanghai.Methods:Data of liver cancer cases diagnosed between 2002 and 2006, including follow-up information and death report, were collected from Shanghai Cancer Registry. Life table and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS). The related demographic characteristics and status were also analyzed to relfect the survival situations of the liver cancer survivors in major areas of Shanghai.Results:In this study, 20 702 liver cancer cases were included in analysis. Five-year OS rate for liver cancer was 11.72%, whereas RS rate was 15.45%. The OS of male liver cancer patients was higher than that of female patients. Patients whose age ranged from 0-34 years had the highest survival rates than patients from other age groups. The survival of patients with hepatocellular carcinoma was higher than that of patients with other histologic types of liver cancer. Signiifcant difference in survival had also been found among patients with various stages of liver cancer. The survival rate of patients with stageⅠliver cancer was much higher than that of patients with stageⅢ andⅣ liver cancers. There was no signiifcant difference in the survival of liver cancer patients between urban and rural residents. Over the past 3 decades, the 5-year OS increased dramatically in Shanghai. Conclusion:The survival of patients with liver cancer in Shanghai is improved signiifcantly. The prognosis is poor compared with other common malignant tumors. It is necessary to strengthen the risk factors and high-risk population control and intervention in the future.
RESUMEN
Background and purpose:Incidence and mortality of gastric cancer have increased gradually in China. Population-based cancer survival rate can relfect improvements in cancer diagnosis and treatment, as well as provide evidence for gastric cancer prevention and control.Methods:Data from gastric cancer incidence and follow-up between 2002 and 2006 were collected by the Shanghai Cancer Registry. Life table and EdererⅡ were used to calculate observed survival (OS) and relative survival (RS).Results:A total number of 28 243 gastric cancer cases were documented between 2002 and 2006 in Shanghai. The 5-year OS and RS of gastric cancer were 32.15% and 45.81%, respectively. Survival rates of gastric cancer varied by age, residence, diagnostic stage, and tumor histological type, but not by gender. Patients aged 35-44 years who were diagnosed at stageⅠ or with tubular adenocarcinoma, had the highest survival rates. Moreover, patients in rural areas had higher 5-year OS than those in urban areas. During the period 2002-2006,both 5-year OS and RS of gastric cancer increased dramatically, as compared with 1972-1976. Conclusion:Survival rates of gastric cancer varied by age, residence, diagnostic stage, and tumor histological type. The 5-year OS and RS signiifcantly increased in Shanghai over the past three decades, but are still far below developed countries. Early diagnosis of gastric cancer would be an effective strategy to improve survival and prognosis of patients with gastric cancer.
RESUMEN
<p><b>OBJECTIVES</b>To analyze the survival of breast cancer molecular subtypes and to examine the effect of therapy on the long-term prognosis of different subtypes.</p><p><b>METHODS</b>This study included 3 586 breast cancer patients with estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2) information in Shanghai Breast Cancer Survival Study, a population-based prospective cohort study established in 2002. Molecular subtypes, based on immunohistochemistry were categorized as follows: Luminal A, Luminal B, HER2, and triple-negative subtype. Characteristics and clinical data were collected through questionnaires and medical records at baseline survey and sequential follow-up surveys. Survival rates of different molecular subtypes were analyzed and compared with Log-rank tests. Multiple Cox regression models were used to evaluate the effect of therapy on long-term prognosis of different molecular subtypes.</p><p><b>RESULTS</b>Among the 3 586 cases, Luminal A, Luminal B, HER2 and triple-negative breast cancer subtypes accounted for 54.5%, 16.6%, 13.9%, and 14.9%, respectively. With a median follow-up of 10.3 years (ranging 0.6 to 12.8 years), the 10-year overall survival (OS) rates for the four subtypes were 82.7% (95% CI: 80.9% to 84.4%), 77.7% (95% CI: 74.1% to 80.8%), 76.3% (95% CI: 72.3% to 79.8%), and 74.8% (95% CI: 70.9% to 78.3%), respectively. The 10-year disease to free survival (DFS) rates were 79.0% (95% CI: 76.7% to 81.0%), 76.0% (95% CI: 71.9% to 79.5%), 73.6% (95% CI: 68.9% to 77.7%), and 74.5% (95% CI: 69.4% to 78.9%), respectively. Significant difference in survival among four subtypes was observed (Log-rank test, P<0.01). Multivariate Cox regression indicated that hormonal therapy can significantly reduce the long-term risk of total mortality and recurrence breast cancer specific mortality among Luminal A subtype patients. Adjuvant chemotherapy could improve the long-term prognosis of triple-negative breast cancer. No benefit from radiotherapy was observed for four subtypes of breast cancer in terms of long-term prognosis.</p><p><b>CONCLUSIONS</b>Molecular subtypes based on ER/PR/HER2 could provide important information to predict breast cancer prognosis. The hormonal status was an important basis for individualized therapy and precision medicine.</p>

Background and purpose:The incidence and mortality of colorectal cancer increased gradually in China, cancer survival rate plays an important role in guiding cancer prevention and treatment.Methods:Data of colorectal cancer cases diagnosed during 2002-2006, follow-up information and death report were from Shanghai Cancer Registry, Life Table and EdererⅡ were used to calculate observed survival (OS) and relative survival (RS), the related demographic characteristics and status were also analyzed to relfect the survival situations of the colorectal cancer survivors in major areas in Shanghai.Results:In this study, 16 682 colon cancer cases and 11 906 rectum cancer cases were included in analysis, 5-year OS rates for colon cancer and rectum cancer were 48.84% and 51.65%, RS rates were 70.50% and 71.31%. Signiifcant difference in survival had been found among the various diagnostic stages, the survival rate in stageⅠ was much higher than those in stageⅢ and stageⅣ. The survival of colorectal cancer patients with different gender, age, tumor histological and residential areas were also found with differences, female was higher than male, age ranged from >44-54 years had the highest survival rates than other age groups. The survival of epithelial tumors was higher than other histologic types in colon cancer, and the survival of non-epithelial tumors was higher than other histologic types in rectum cancer. Over the past 3 decades, the 5-year OS increased dramatically in Shanghai. Conclusion:The level of survival of colorectal cancer in Shanghai is similar with it in developed counties. Colorectal cancer survival rate with different population characteristics may provide suggestions and evidence for further improvement of early screening, diagnosis and treatment.
RESUMEN
Objective:To analyze the incidence trend, current status and survival period of young patients with lung cancer aged from 15 to 44 years in Shanghai between 2002 to 2005. Methods:All the data were collected from the database of registration and ma-nagement system of diagnosed cancer cases in Shanghai city organized by Shanghai Municipal Center for Disease Control & Prevention. The incidence trend was analyzed by using APC(annual percent change)model. The survival period and median survival time were calculated by using SPSS 12.0 software and life table method. The univariate and multivariate analyses were analyzed by using Kaplan-Meier and COX regression model, respectively.Results:A total of 972 young patients with lung cancer who aged from 15 to 44 years were diagnosed in Shanghai between 2002 and 2005, accounting for 3.09% of the whole percentage of adenocarcinoma in young patients was higher than that in whole lung cancer population at the same period, while the TNM stage was not significantly different between male and female young patients. Multivariate analysis demonstrated that gender, pathological classification and TNM stage were independent prognostic factors for young patients with lung cancer. Conclusion:The lung cancer had different characteristics in young patients compared with that in whole lung cancer population in Shanghai city. It was necessary to further investigate the biologic behavior of lung cancer in young patients.
RESUMEN
Objective:To investigate the understanding of cancer pain by medical doctors and its therapeutic status in Shanghai. Methods:We recruited 1 982 medical physicians from 106 secondary and tertiary hospitals in Shanghai city from January to March in 2007. The understanding and the therapeutic status of cancer pain were investigated by conducting a questionnaire survey and the results were statistically analyzed.Rusults:There were 52.3% physicians who believed that they understand the treatment protocol of the Three-step Analgesic Ladder regimen. The rate increased by 21.6 percentage point compared with the results in 1999. The understanding degree of oncologists was significantly better than non-oncologists. There were 16.8% physicians giving the correct answers on the three main principles of the dosage titration in analgesic management. The correct rate of oncologists was significantly higher than that of non-oncologists. Opium with strong analgesic effect had become the first choice for severe cancer pain, and the use of pethidine (Dolantin) for severe cancer pain decreased significantly.The pain was significantly relieved in 74.8% patients. The pain-relieving rate increased by 25.4 percentage point compared with the results in 1999. There were 81.1% medical doctors confirming the effect of pain treatment and among them oncologists were more optimistic to therapeutic outcome than others. There were 93.3% physicians who agreed that it was necessary to carry out the standardized training of cancer pain treatment and the requirement of non-oncologists were much emergent. The over-strict controls by the hospitals and the regulations were the main obstacles for using analgesic drugs.Conclusion:The understanding of medical doctors and the diagnostic and therapeutic levels of cancer pain were improved significantly compared with those in 1999. But more training of cancer pain treatment are still required to publicize the standardized therapy and overcome the obstacles of using analgesic drug.
