Analysis of long-term trend changes in breast cancer incidence and death among females in Shanghai,1973-2017 / 肿瘤

Objective:To describe the long-term characteristics and trend changes in the incidence and mortality of female breast cancer in Shanghai from 1 973 to 2017,aiming to provide references for exploring the etiology of breast cancer and formulating strategies and measures for prevention,intervention and control. Methods:Joinpoint software was used to analyze the trend changes in the incidence and mortality of female breast cancer in Shanghai from 1 973 to 2017,and an age-period-cohort model was constructed to explore the effects of age,year of diagnosis,and birth cohort on long-term trend changes. Results:From 1 973 to 2017,there were 68 192 new cases of female breast cancer in Shanghai,with a diagnosed rate of 31.72/100 000.The incidence rate continued to rise,and the risk of the disease continued to rise from the age of 20 years,and the rise rate accelerated significantly after the age of 40 years.There were 21 535 female breast cancer deaths from 1 973 to 2017.The mortality rate was stable,with a death rate of 8.62/100 000,and the risk of death increased significantly from the age of 45 years.The effects of age,period and cohort had a significant impact on the incidence of breast cancer(P＜0.01),while the increase in mortality rate was related to age and cohort effects(P＜0.01). Conclusion:The incidence rate of female breast cancer in Shanghai is still rising rapidly,and the mortality trend is generally stable,suggesting that the treatment is effective and the quality of life is improved.However,breast cancer is still the main malignant tumor among females in Shanghai.It should be continued to implement prevention and control strategies such as lifestyle intervention and screening of high-risk individuals to further strengthen the prevention and control of breast cancer.

Colorectal cancer incidence and mortality trends in urban Shanghai,China from 1973 to 2017:a Joinpoint regression and age-period-cohort analysis / 肿瘤

Objective:To describe the epidemiological features and temporal trends of colorectal cancer in urban Shanghai from 1973 to 2017. Methods:Data on colorectal cancer in urban Shanghai was obtained through Shanghai Cancer Registry and Vital Statistics System.Joinpoint analysis was used to describe the temporal trends and annual percent change(APC)and age-period-cohort analysis was used to estimate the association between age,period and birth cohort and colorectal cancer. Results:A total of 105 847 cases and 60 447 deaths of colorectal cancer were diagnosed in urban Shanghai over the 45-year study period.Both the number of new cases and the number of deaths showed an increasing trend.In the same period,the age-standardized incidence of colorectal cancer in urban areas of Shanghai increased significantly from 14.1/100 000 in 1973 to 27.7/100 000 in 2017,while the age-standardized mortality rate increased from 8.2/100 000 to 10.7/100 000.The overall average annual age-standardized incidence and mortality rates were 20.4/100 000 and 11.0/100 000,respectively.With the increase of age,the age-standardized morbidity and mortality of colorectal cancer showed an obvious upward trend.Taking 1993-1997 as reference,the risk of colorectal cancer in Shanghai reached the highest in 2013-2017,and the corresponding relative risk was 1.2(95％confidence interval:1.2-1.3),while the lowest was 0.9(95％confidence interval:0.8-1.0)during 1973-1977.Mortality risk,on the contrary,decreased with the increase of time.Before 1953-1957,the risk of colorectal cancer in urban Shanghai increased with the increase of birth cohort time,and then showed a downward trend.There was a corresponding decline in the risk of colorectal cancer death among people born after 1957. Conclusion:The incidence and mortality of colorectal cancer in Shanghai showed an increasing trend from 1973 to 2017,but the prevalence trend of colorectal cancer is still different among different populations.

Diagnostic characteristics and survival analysis of screen-detected colorectal cancer in Shanghai,2013-2015 / 肿瘤

Objective:To analyze and compare the survival rate between patients with screen-detected and non-screening detected colorectal cancer in Shanghai from 2013 to 2015. Methods:Patients with screen-and non-screening detected colorectal cancer from 2013 to 2015 were collected from Shanghai Colorectal Cancer Screening Program and the Population-Based Cancer Registry.The results presented were based on data collected by December 31,2020.Survival rates were stratified by year of diagnosis,gender,site,age-group,stage at diagnosis and histopathologic category when analyzed.The 5-year observed survival rates were calculated based on the life table,and then the cumulative expected survival rates were calculated according to the Ederer Ⅱ method.Finally,the 5-year relative survival rate was calculated.The COX proportional hazard regression model was used for the multivariate analysis. Results:2 108 patients with screening-detected colorectal cancer and 14 154 patients with non-screening colorectal cancer from 2013 to 2015 were included in the analysis,and the proportions of phase Ⅰ were 35.53％and 9.33％,respectively.The stage distribution of colorectal cancer was significantly different between patients with screen-detected and non-screening detected colorectal cancer(P＜0.05).The 5-year relative survival rates of patients with screen-detected and non-screening detected colorectal cancer were 84.66％(95％confidence interval:82.87％-86.45％)and 63.51％(95％confidence interval:62.64％-64.38％),respectively.The patients with screen-detected colorectal cancer had a significantly improved 5-year relative survival rate in comparison with the patients with non-screening detected colorectal cancer.The survival rates of females in both groups were higher than those of males.The relative survival rate decreased with the increase of age and gradually decreased with the increase of stage at diagnosis.The relative survival rate of patients with non-screening detected colon cancer was significantly lower than that of patients with rectal cancer. Conclusion:Patients with colorectal cancer found at screening had a significantly improved survival rate compared to patients with non-screening detected colorectal cancer.Staging at diagnosis is a key factor,which indicates that enhancing screening and early diagnosis has important meaning to further improve the survival of patients with colorectal cancer and reduce the burden of disease.

Survival analysis of liver cancer in Shanghai:a population-based study from 2002 to 2013 / 肿瘤

Objective:To investigate the survival rates of patients with liver cancer in Shanghai from 2002 to 2013. Methods:Data on new cases and deaths of liver cancer patients withfollow-up information from 2002 to 2013 were obtained from the Population-Based Cancer Registry and Vital Statistics System of the Shanghai Municipal Center for Disease Control and Prevention.Incidence and survival rates were stratified by year of diagnosis,gender,district,age-group and stage at diagnosis for analysis.Statistical indicators,such as case numbers,proportions,median age and mean age were calculated.The 1-to 5-year observed survival rates were calculated based on the life table method.The probabilities of surviving from 0 to 99 years old were estimated with the Elandt-Johnson model,and then cumulative expected survival rates were calculated using the Ederer Ⅱ method.Finally,the 1-to 5-year relative survival rates were calculated. Results:A total of 49 455 new cases of liver cancer were diagnosed from 2002 to 2013 in Shanghai,including 35 115 males and 14 340 females.The ratio of males to females was 2.45:1.The proportions of stage Ⅰ,stage Ⅳ and stage unknown were 3.32％,13.93％and 69.13％,respectively.The median survival time of patients with liver cancer diagnosed from 2002 to 2013 was 0.77 years,the 5-year observed survival rate was 13.23％,and the 5-year relative survival rate was 14.47％.According to the 5-year observed survival rate and 5-year relative survival rate of the cases,both survival indicators were higher in urban areas than in suburban areas,higher in males than in females,higher in cases under 45 years of age than in those over 75 years of age,higher in cases diagnosed from 2011 to 2013 than those diagnosed from 2002 to 2004.Additionally,the survival rate of cases decreased with increasing stage at diagnosis. Conclusion:With the continuous improvement of the diagnosis and treatment of liver cancer in Shanghai,the survival rate of patients with liver cancer has shown a significant upward trend over time.However,compared with various malignant tumors such as gastric cancer and breast cancer,the improvement effect of liver cancer survival rate is still not significant.Additionally,a high proportion of cases with unknown clinical stage at the time of diagnosis and a low survival rate of stage Ⅳ cases were observed.This study provides a basis for the prevention and research of liver cancer.

Chromosomal aberrations detection in chronic lymphocytic leukemia by conventional cytogenetics using DSP30 and IL-2 / 中华血液学杂志

Objective@#To study the value of unmethylated cytosine guanine dinucleotide oligodeoxynucleotide (DSP30) and IL-2 in the conventional cytogenetic (CA) detection of the chromosomal aberrations in chronic lymphocytic leukemia (CLL) .@*Methods@#Bone marrow or peripheral blood cells of CLL patients were cultured with DSP30 plus IL-2 for 72 h, following which R-banding analysis was conducted. Fluorescence in situ hybridization (FISH) was performed in 85 patients. CA results were compared with data obtained by FISH.@*Results@#Among 89 CLL patients, the success rate of chromosome analysis was 94.38% (84/89) . Clonal aberrations were detected in 51 patients (51/84, 60.71%) . Of them, 27 (27/51, 52.94%) were complex karyotype. Among 85 CLL patients tested by FISH, chromosomal abnormalities were detected in 74 (74/85, 87.06%) patients, of which 2 (2/74) patients were complex karyotypes, accounting for 2.70%. Of the 85 CLL patients examined by FISH, 50 had abnormal karyotype analysis, 30 had normal karyotype, 5 failed to have chromosome analysis. Among them, 25 cases showed clonal aberrations by FISH assay but normal by CA, and 4 cases were normal by FISH but displayed aberrations in chromosome analysis, and totally 78 (91.76%) cases with abnormality detected by the combination of the two methods. The frequency of 13q- abnormality detected by FISH was significantly higher than that by CA analysis (69.41%vs 16.67%, P<0.001) , while the frequency of 11q-,+12 and 17p- detected by two methods showed no significant difference (P>0.05) . The detection rate of complex abnormalities in conventional karyotype analysis was higher than that in FISH (50.98%vs 2.70%) . In addition, 11 low-risk and 9 intermediate-risk patients according to FISH results showed complex karyotype by cytogenetics, and were classified into high-risk cytogenetic subgroup.@*Conclusion@#DSP30 and IL-2 are effective in improving the detection rate of CA in CLL patients (60.71%) and CA is more effective to detect complex karyotype. However, FISH had a higher overall abnormality detection rate (87.06%) than CA, especially for 13q-. The combination of CA and FISH not only enhanced the detection rate of clonal aberrations to 91.76%, but also provided more precise prognosis stratification for CLL patients, thus to provide more information for clinical implication.

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.

Study on the Specificity of Meridian Points Via the Effect of Acupuncture at the Primary Points of the Three Yin Meridians of the Foot on Blood Pressure in an Animal Model of High/low Blood Pressure / 上海针灸杂志

Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

Survival analysis of patients with lung cancer in Shanghai / 中国癌症杂志

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.

The patterns of head and neck cancer incidence in Shanghai from 2003 to 2012 / 中国癌症杂志

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.
