ABSTRACT
Objective@#To analyze the patterns of female breast cancer and their incidence in Shanghai during 2003-2012, and to compare them with international data.@*Methods@#The data of female breast cancer cases diagnosed between 2003 and 2012 were collected from the Shanghai Cancer Registry. The record of cancer cases included the patient's name, gender, date of birth, permanent and residential address, diagnosis site or name, histological type, date of first diagnosis, diagnostic basis and diagnostic stage, etc. Data source of cancer incidence of World, Developed Countries, Developing Countries, East Asia and China in 2012 sourced from GLOBOCAN 2012 database of the WHO International Agency for Research on Cancer (IARC); and the data of USA during 2008-2012 was collected from SEER 18 database from Surveillance, Epidemiology, and End Results Program of the National Cancer Institute (NCI). Incidence indicators of Shanghai female breast cancer were calculated, including the average cases, median age, average age, proportion, crude rate, age-specific rate and age-standardized rate.@*Results@#During 2003-2012, 41 991 new cases of female breast cancer were diagnosed in Shanghai, with an average of 4 199 cases per year, accounting for 17.23% among total new female cancer cases, ranking first in female cancer incidence in Shanghai during 2003-2012, with a crude incidence rate of 60.90 per 100 000 and an age-standardized incidence rate of 33.90 per 100 000. During 2008-2012, an average 4 528 new cases of female breast cancer was diagnosed per year in Shanghai, with 16.97% among total female cancer cases. The median age was 56 years old and the mean age was 57.73 years old. The crude rate was 64.23 per 100 000 and the age-standardized rate was 35.00 per 100 0000, which was higher than those of China (22.1 per 100 000), Eastern Areas (27.0 per 100 000) and Developing Counties (31.3 per 100 000), and lower than that of World (43.1 per 100 000), and Yellow Race Population of USA (68.77 per 100 000). During 2003-2007, on average, 3 869 new cases of female breast cancer were diagnosed per year in Shanghai, accounting for 17.54% of total female cancer cases. The median age was 53 years old and the mean age was 56.44 years old. The crude rate was 57.42 per 100 000 and the age-standardized rate was 32.69 per 100 000. There was a continuing peak stage spanned 25 years old from 50 to 74 years old, during 2008-2012. Compared with those of 2003-2007, the beginning age group of the continuing peak stage was delayed for 5 years old and the ending age group was delayed for 10 years old.@*Conclusion@#The age-standardized incidence rate in Shanghai was higher than those of China, Eastern Areas and Developing Counties, and lower than that of World, and that of Yellow Race Population of USA; Compared with 2003-2007, the crude rate and age-standardized rate increased, the median age, mean age and the beginning and ending age group of the continuing peak stage were delayed.
ABSTRACT
Background and purpose: The incidence and mortality of lung cancer ranked first in China. This study aimed to describe lung cancer survival in Shanghai, and provide background information for cancer prevention and treatment evaluation. Methods: Data of lung cancer cases diagnosed during 2002-2006, follow-up information and death report were collected from Shanghai Cancer Registry. Life table method and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS) respectively. Related demographic characteristics and status were also analyzed to present the survival situations of the lung cancer survivors in Shanghai. Results: In this study, 41802 lung cancer cases were included in analysis. The 5-year OS and RS for lung cancer were 13.75% and 20.23% respectively, and median survival time was 318 days. Survival rate was higher among females than males, with the 5-year OS of 15.49% and 13.00% respectively. The 5-year OS was higher among suburban residents (14.25%) than urban residents (13.23%). Survival rates decreased with increasing age and advanced stage. Patients aged 0-34 had a 5-year OS of 38.21%, while patients aged above 75 had a 5-year OS of 5.48%. Patients diagnosed with stage Ⅰ had a 5-year OS of 55.47%, while patients diagnosed with stage Ⅳ had a 5-year OS of 5.27%. Survival of lung cancer patients differed by tumor histological subtype. The 5-year OS of squamous lung cancer (24.40%) was higher than other histological types, followed by adenocarcinoma (22.26%), large cell (20.27%) and small cell lung cancer (12.22%). From 1972-1976 to 2002-2006, the 5-year OS of urban male patients increased from 6.8% to 12.4%, and 5-year OS of urban female patients increased from 7.3% to 14.9%. Analysis of RS gave the similar results. Conclusion: During the past 30 years, survival rate of lung cancer patients in Shanghai improved steadily, and the survival condition is above average among different countries and areas. However, survival rate of lung cancer is still low compared with other types of cancer. Future focus should be placed on the control of tobacco smoking, early detection by low-dose helical computed tomography and targeted therapy to further improve lung cancer survival.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
Objective To observe the clinical efficacy of superficial needling in treating temporomandibular joint disorder. Method Sixty patients with temporomandibular joint disorder were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by superficial needling, and the patients were asked to repeatedly open and close mouth after the treatment; the control group was intervened by regular acupuncture. The treatment was given once a day, 10 d as a treatment course. The clinical efficacies were compared after 2 treatment courses.Result After the first treatment course, the total effective rate was 89.7% in the treatment group versus 86.2% in the control group; after the second course, the total effective rate was 96.6% in the treatment group versus 93.1% in the control group. There was a significant difference in comparing the therapeutic efficacy between the two groups after the second course (P<0.05). The relapse rate was 5.0% in the treatment group versus 33.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Superficial needling is an effective method in treating temporomandibular joint disorder.
ABSTRACT
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.
