Methods： Population-based cancer registry data in Jiangsu province were collected during 2003-2011. Crude rates, age-specific rates, age-standardized rates and annual percent changes of incidence and mortality were calculated to describe the epidemiologic characteristics and time trends. Patients diagnosed from 2003 to 2005 were chosen for analyzing the survival status of breast cancer. Results： From 2003 to 2011, 17,605 females were diagnosed with breast cancer and 4,883 died in selected registry areas in Jiangsu province. The crude incidence rate was 25.18/100,000, and the age-standardized rates by Chinese population （ASRC） and by world population （ASRW） were 19.03/100,000 and 17.92/100,000, respectively. During the same period, the crude mortality rate was 6.98/100,000 and the ASRC and ASRW were 4.93/100,000 and 4.80/100,000, respectively. From 2003 to 2011, the incidence and mortality increased with annual percent change of 11.37% and 5.78%, respectively. For survival analysis, 1,392 patients in 7 areas were identified in 2003-2005 and finished 5 years of follow-up. Survival rates were found to decrease with survival years, the 5-year observed survival rate was 45.9% and the relative survival rate was 52.0%. We also found that the survival rate varied across the province, which was lower in the north and higher in the south of Jiangsu province. Conclusions： Breast cancer has become a significant public health problem in Jiangsu province and China. More resources should be invested in primary prevention, earlier diagnosis and better health services in order to increase survival rates among Chinese females.展开更多

To identify very old candidates for radical prostatectomy with the highest probability of long-term survival, we studied 47 consecutive men who underwent radical prostatectomy between 1992 and 2005 at an age of 75 years or older. A heuristic approach was used to search for subgroups with particularly high long-term survival. Several two-sided comorbidity measures and combinations of these measures were investigated to find classifications best identifying healthy, long-living elderly candidates for radical prostatectomy. Four of the 25 two-sided comorbidity classifications or combinations reached the significance level with hazard ratios between 4.00 and 4.80. After 10 years, patients identified as healthy patients according to these comorbidity measurements had exhibited relative survival rates between 129% and 137% and overall survival rates between 86% and 95%, whereas those with comorbidities had exhibited relative survival rates of only 66%-84% and overall survival rates of 44%-58%. In conclusion, classifying comorbidity may identify a meaningful proportion of men selected for radical prostatectomy at an age of 75 years or older with an excellent long-term survival probability superseding that of the general population.展开更多

METHODS： All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection （632 patients） were selected from the Amsterdam Cancer Registry. For patients with recurrent disease, information on treatment of the recurrence was collected from the medical records. RESULTS： Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients （10%）. Thirty-two patients had an isolated local recurrence. Ten of these 32 patients （31%） underwent radical re-resection and experienced the highest survival （three quarters survived for at least 3 years）. Eight patients （25%） underwent non-radical surgery （median survival 24 rno）, seven patients （22%） were treated with radio- and/or chemotherapy without surgery （median survival 15 mo） and seven patients （22%） only received best supportive care （median survival 5 too）. Distant dissemination occurred in 124 patients （20%） of whom 30 patients also had a local recurrence. The majority （54%） of these patients were treated with radio- and/or chemotherapy without surgery （median survival 15 mo）. Twenty-seven percent of these patients only received best supportive care （median survival 6 mo）, while 16% underwent surgery for their recurrence. Survival was best in the latter group （median survival 32 mo）. CONCLUSION： Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME, patients can benefit from additional treatment, especially if a radical resection is feasible.展开更多

[Method] F. chinensis individuals were assigned into six groups, and each group was fed with a diet containing 0（Control）, 0.5%（Group E0.5）, 1.0%（Group E1.0）, 2.5%（Group E2.5）, 5.0%（Group E5.0） or 10.0% PHB（Group E10.0）. The mortality rate and relative percent of survival（RPS） of each group were calculated after 6 weeks. Meanwhile, the total antioxidant capacity（T-AOC）, the activity of acid phosphatase（ACP）, peroxidase（POD） and catalase（CAT）, and the content of malondialdehyde（MDA） in hepatopancreas and serum were measured,and their correlation with PHB concentration was analyzed. [Result] The RPS in PHB treated shrimps increased initially and decreased subsequently with increasing PHB concentration. RPS of Group E1.0 was the highest, showing significant difference from that of other groups（ P 〈0.05）.With the increase in PHB concentration, the activity of immunity related enzymes changed in a similar pattern with RPS： increasing at first and decreasing subsequently. In addition, the activity of the enzymes was elevated in the 2nd and 3rd weeks of PHB administration. Among them, T-AOC in serum of groups E1.0 and E2.5, T-AOC in hepatopancreas of Group E1.0, ACP activity in serum of groups E1.0 and E2.5, ACP activity in hepatopancreas of Group E1.0, CAT activity in groups E0.5, E1.0 and E2.5, CAT activity in hepatopancreas of groups E0.5, E1.0 and E10.0, POD activity in both serum and hepatopancreas of groups E0.5, E1.0 and E2.5, SOD activity in both serum and hepatopancreas of Group E1.0, MDA content in serum of Group E1.0 and MDA content in hepatopancreas of groups E0.5 and E1.0 showed significant difference from those of other groups（P〈0.05）. [Conclusion] PHB can improve the immunity of F. chinensis, 1.0% in feed has the best effect, and the total enzyme activity reaches the highest level in the 2nd and 3rd weeks of PHB administration.展开更多

文摘Aim:To describe the global pattern and trend of liver cancer survival,using data from the population-based studies or cancer registration.Methods:By searching CNKI,Wanfang Data,PubMed,Web of Science,EMBASE and SEER.All population-based survival studies of liver cancer from 1 January 2000 to 30 April 2020 were collected and evaluated by patient gender,time period,and country.The overall or age-standardized five-year relative survival rate was used to describe the pattern and changes in liver cancer survival over the past decades.Results:Globally,the highest age-standardized five-year relative survival rate was observed in Italy(18.0%,2005-2007)and the highest overall five-year relative survival rate was observed in Korea(34.6%,2012-2016),when compared to other countries.The most remarkable increase in overall five-year relative survival rate can be seen in Korea(from 10.7%during 1993-1995 to 34.6%during 2012-2016).In general,worldwide,the five-year relative survival rate of younger patients with liver cancer was higher than old people.For most countries,the five-year relative survival rate of liver cancer was slightly higher in women than in men.In China,the overall five-year relative survival rate of liver cancer in Taiwan was higher than that in other areas,while Cixian of Hebei and Qidong of Jiangsu were lower.Conclusion:Over the past decades,the survival rates of liver cancer have gradually improved,but great variations are also observed globally.Worldwide,younger patients with liver cancer have experienced a better prognosis.Gender disparity in liver cancer survival was not obvious.

文摘Objective:This is a comprehensive overview of long-term cancer survival in Zhejiang Province,China.Hybrid analysis,a combination of cohort and period analysis,has been proposed to derive up-to-date cancer survival estimates.Using this approach,we aimed to timely and accurately analyze the 5-year relative survival(RS)and net survival(NS)in cancer registries of Zhejiang Province,China.Methods:A total of 255,725 new cancer cases diagnosed during 2013-2017 were included in 14 cancer registries in Zhejiang Province,China,with a follow-up on vital status until the end of 2019.The hybrid analysis was used to calculate the 5-year RS and 5-year NS during 2018-2019 for overall and stratifications by sex,cancer type,region,and age at diagnosis.Results:During 2018-2019,the age-standardized 5-year RS and NS for overall cancer in Zhejiang was 47.5%and 48.6%,respectively.The age-standardized 5-year RS for cancers of women(55.4%)was higher than that of men(40.0%),and the rate of urban areas(49.7%)was higher than that of rural areas(43.1%).The 5-year RS declined along with age,from 84.4%for ages<45 years to 23.7%for ages>74 years.Our results of the RS and NS showed the similar trend and no significant difference.The top five cancers with top age-standardized 5-year RS were thyroid cancer(96.0%),breast cancer(84.3%),testicular cancer(79.9%),prostate cancer(77.2%),and bladder cancer(70.6%),and the five cancers with the lowest age-standardized 5-year RS were pancreatic cancer(6.0%),liver cancer(15.6%),gallbladder cancer(17.1%),esophageal cancer(22.7%),and leukemia(31.0%).Conclusions:We reported the most up-to-date 5-year cancer RS and NS in Zhejiang Province,China for the first time,and found that the 5-year survival for cancer patients in Zhejiang during 2018-2019 was relatively high.The population-based cancer registries are recognized as key policy tools that can be used to evaluate both the impact of cancer prevention strategies and the effectiveness of health systems.
