| 2 | Increasing the frequency of CIK cells adoptive immunotherapy may decrease risk of death in gastric cancer patients显示文摘AIM: To analyze the correlation between cytokineinduced killer (CIK) cells adoptive immunotherapy and cancer-related death in gastric cancer patients. METHODS: One hundred and fifty-six gastric cancer patients after operation at the Third Affiliated Hospital of Soochow University were enrolled in this study. Their clinical data including demographic characteristics, operation time, tumor size, pathological type and staging, tumor metastasis, outcome of chemotherapy or CIK cells adoptive immunotherapy, survival time or time of death were collected with a standard structured questionnaire. Kaplan-Meier method was used to estimate the median survival time, and the 2- and 5- year survival rates. Hazard risk (HR) and 95% confidence interval (95% CI) of CIK cells adoptive immunotherapy for gastric cancer were calculated using the two-stage time-dependent covariates Cox model. RESULTS: The survival time of gastric cancer patients was longer after CIK cells adoptive immunotherapy than after chemotherapy (χ 2 = 10.907, P = 0.001). The median survival time of gastric cancer patients was also longer after CIK cells adoptive immunotherapy than after chemotherapy (49 mo vs 27 mo, P < 0.05). The 2- and 5-year survival rates of gastric cancer patients were significantly higher after CIK cells adoptive immunotherapy than after chemotherapy (73.5% vs 52.6%, 40.4% vs 23.9%, P < 0.05). A significant difference was observed in the survival curve for patients who received CIK cells adoptive immunotherapy (0, 1-10, 11-25, and over 25 frequencies) (χ 2 = 14.534, P = 0.002). The frequencies of CIK cells adoptive immunotherapy were significantly related with the decreasing risk of death in gastric cancer patients after adjustment for sex and age of the patients, tumor stage and relapse (HR = 0.54, 95% CI: 0.36-0.80) when the first stage Cox model was used to define the subjects who remained alive beyond 36 mo as survivors. However, no correlation was observed between the frequencies of death in CIK cells adoptive immunotherapy and the risk of gastric cancer patients (HR = 1.09, 95% CI: 0.63-0.89) when the second stage Cox model was used to define the subjects who survived for more than 36 mo as survivors. CONCLUSION: The survival time of the gastric cancer patients treated with chemotherapy combined with CIK cells adoptive immunotherapy is significantly longer than that of the patients treated with chemotherapy alone and increasing the frequency of CIK cells adoptive immunotherapy seems to benefit patients more. | Jing-Ting Jiang, Chang-Ping Wu, Lu-Jun Chen, Xiao Zheng, Department of Tumor Biological Treatment, Third Affiliated Hospital of Soochow University, Changzhou 213003, Jiangsu Province, China Yi-Bei Zhu, Jing Sun, Xue-Guang Zhang, Key Laboratory of Stem Cell of Jiangsu Province, Institute of Biotechnology, Key Laboratory of Clinical Immunology of Jiangsu Province, Soochow University, Suzhou 215123, Jiangsu Province, China Yue-Ping Shen, Wen-Xiang Wei, Department of Medicine, Soochow University, Suzhou 215123, Jiangsu Province, China Bin-Feng Lu, Department of Immunology, University of Pitts- burgh School of Medicine, Pittsburgh, PA 15261, United States | 2010 | World Journal of Gastroenterology2010,16,48: | 82 |
| 3 | XS0601 REDUCES THE INCIDENCE OF RESTENOSIS: A PROSPECTIVE STUDY OF 335 PATIENTS UNDERGOING PERCUTANEOUS CORONARY INTERVENTION IN CHINA显示文摘Background XS0601, consisting of active ingredients (Chuangxiongol and paeoniflorin), has been shown to inhibit arterial neointimal hyperplasia in animal models and in preliminary human studies. The objective of this study was to evaluate the safety and efficacy of XS0601 in preventing restenosis following percutaneous coronary intervention (PCI). Methods A multi-center, randomized, double-blind, placebo-controlled trial was conducted. A total of 335 patients were randomized into treatment with the oral administration of XS0601, or a placebo for 6 months after successful PCI. Angiographic follow-up was scheduled at 6 months, and clinical follow-ups performed at 1, 3 and 6 months after PCI. The primary end point was angiographic restenosis. The secondary end points were the combined incidence of death, target lesion nonfatal myocardial infarction, repeat angioplasty, and coronary artery bypass graft surgery. Results A total of 308 patients (91.9%) completed the study and 145 cases (47.1%) received angiographic follow-up. The restenosis rates were significantly reduced in the XS0601 group as compared with the placebo group (26.0% vs. 47.2%, P < 0.05), and the minimum lumen diameter (MLD) was greater [(2.08 ± 0.89) mm for XS0601 vs. (1.73 ± 0.94) mm for placebo, P < 0.05]. XS0601 also significantly reduced the combined incidence of major adverse cardiac event (10.4% in the XS0601 group vs. 22.7% in the placebo group, P < 0.05). The incidence of recurrent angina at 3 and 6 months after PCI was also significantly reduced in XS0601 group (7.1% and 11.0%) as compared with those in placebo group (19.5% and 42.9%) (P < 0.05). No significant side effects occurred within the 6-month follow-up period in the XS0601 group. Conclusion Administration of XS0601 for 6 months is demonstrated to be safe and effective in reducing restenosis in post-PCI patients. | CHEN Ke-ji SHI Da-zhuo XU Hao LUE Shu-zheng LI Tian-chang KE Yuan-nan ZHANG Min-zhou LU Xiao-yan SUN Rui-yuan YOU Shi-jie | 2006 | Chinese Medical Journal2006,,1: | 83 |

| 6 | UNSTEADY FLOW ANALYSIS AND EXPERIMENTAL INVESTIGATION OF AXIAL-FLOW PUMP显示文摘The three-dimensional unsteady turbulent flow in axial-flow pumps was simulated based on Navier-Stoke solver embedded with k-ε RNG turbulence model and SIMPLEC algorithm.Numerical results show that the unsteady prediction results are more accurate than the steady results,and the maximal error of unsteady prediction is only 4.54%.The time-domain spectrums show that the static pressure fluctuation curves at the inlet and outlet of the rotor and the outlet of the stator are periodic,and all have four peaks and four valleys.The pressure fluctuation amplitude increases from the hub to the tip at the inlet and outlet of the rotor,but decreases at the outlet of the stator.The pressure fluctuation amplitude is the greatest at the inlet of the rotor,and the average amplitude decreases sharply from the inlet to the outlet.The frequency spectrums obtained by Fast Fourier Transform(FFT) show that the dominant frequency is approximately equal to the blade passing frequency.The static pressure on the pressure side of hydrofoil on different stream surfaces remains almost consistent,and increases gradually from the blade inlet to the exit on the suction side at different time steps.The axial velocity distribution is periodic and is affected by the stator blade number at the rotor exit.The experimental results show that the flow is almost axial and the pre-rotation is very small at the rotor inlet under the conditions of 0.8 QN -1.2 QN.Due to the clearance leakage,the pressure,circulation and meridional velocity at the rotor outlet all decrease near the hub leakage and tip clearance regions. | ZHANG De-sheng SHI Wei-dong CHEN Bin GUAN Xing-fan | 2010 | Journal of Hydrodynamics2010,22,1: | 111 |

| 11 | Cancer Incidence and Mortality in China,2007显示文摘Objective:Cancer incidence and mortality data collected from population-based cancer registries were analyzed to present the overall cancer statistics in Chinese registration areas by age,sex and geographic area in 2007.Methods:In 2010,48 cancer registries reported cancer incidence and mortality data of 2007 to National Central Cancer Registry of China.Of them,38 registries' data met the national criteria.Incidence and mortality were calculated by cancer sites,age,gender,and area.Age-standardized rates were described by China and World population.Results:The crude incidence rate for all cancers was 276.16/100,000(305.22/100,000 for male and 246.46/100,000 for female;284.71/100,000 in urban and 251.07/100,000 in rural).Age-standardized incidence rates by China and World population were 145.39/100,000 and 189.46/100,000 respectively.The crude mortality rate for all cancers was 177.09/100,000(219.15/100,000 for male and 134.10/100,000 for female;173.55/100,000 in urban and 187.49/100,000 in rural).Age-standardized mortality rates by China and World population were 86.06/100,000 and 116.46/100,000,respectively.The top 10 most frequently common cancer sites were the lung,stomach,colon and rectum,liver,breast,esophagus,pancreas,bladder,brain and lymphoma,accounting for 76.12% of the total cancer cases.The top 10 causes of cancer death were cancers of the lung,liver,stomach,esophagus,colon and rectum,pancreas,breast,leukemia,brain and lymphoma,accounting for 84.37% of the total cancer deaths.Conclusion: Cancer remains a major disease threatening people's health in China. Prevention and control should be enhanced, especially for the main cancers. | Wan-qing Chen Hong-mei Zeng Rong-shou Zheng Si-wei Zhang Jie He | 2012 | Chinese Journal of Cancer Research2012,24,1: | 88 |
| 12 | The incidences and mortalities of major cancers in China, 2009显示文摘In 2012, the National Central Cancer Registry (NCCR) of China collected cancer registration information for the year 2009 from local cancer registries and analyzed it to describe the incidences and mortalities of cancers in China. Based on the data quality criteria from NCCR, data from 104 registries covering 85,470,522 people (57,489,009 in urban areas and 27,981,513 in rural areas) were checked and evaluated. The data from 72 registries were qualified and accepted for the cancer registry annual report in 2012. The total cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphologically verified cases accounted for 67.23%, and 3.14% of the incident cases only had information from death certifications. The crude incidence in the Chinese cancer registration areas was 285.91/ 100,000 (317.97/100,000 in males and 253.09/100,000 in females). The age-standardized rates for incidences based on the Chinese standard population (ASRIC) and the world standard population (ASRIW) were 146.87/100,000 and 191.72/100,000, respectively, with a cumulative incidence of 22.08%. The cancer mortality in the Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females). The age-standardized rates for mortalities based on the Chinese standard population (ASRMC) and the world standard population (ASRMW) were 85.06/100,000 and 115.65/100,000, respectively, and the cumulative mortality was 12.94% . Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreatic cancer, encephaloma, lymphoma, female breast cancer, and cervical cancer were the most common cancers, accounting for 75% of all cancer cases. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia, and lymphoma accounted for 80% of all cancer deaths. The cancer registration's population coverage has been increasing, and its data quality is improving. As the basis of the cancer control program, the cancer registry plays an important role in directing anticancer strategies in the medium and long term. Because cancer burdens are different in urban and rural areas in China, prevention and control efforts should be based on practical situations. | Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Guanglin Li Lingyou Wu Jie He | 2013 | Chinese Journal of Cancer2013,32,3: | 111 |
| 13 | Report of incidence and mortality in China cancer registries, 2009显示文摘Objective: The National Central Cancer Registry (NCCR) collected cancer registration data in 2009 from local cancer registries in 2012, and analyzed to describe cancer incidence and mortality in China. Methods: On basis of the criteria of data quality from NCCR, data submitted from 104 registries were checked and evaluated. There were 72 registries' data qualified and accepted for cancer registry annual report in 2012. Descriptive analysis included incidence and mortality stratified by area (urban/rural), sex, age group and cancer site. The top 10 common cancers in different groups, proportion and cumulative rates were also calculated. Chinese population census in 1982 and Segi's population were used for age-standardized incidence/mortality rates. Results: All 72 cancer registries covered a total of 85,470,522 population (57,489,009 in urban and 27,981,513 in rural areas). The total new cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphology verified cases accounted for 67.23%, and 3.14% of incident cases only had information from death certifications. The crude incidence rate in Chinese cancer registration areas was 285.91/100,000 (males 317.97/100,000, females 253.09/100,000), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 146.87/100,000 and 191.72/100,000 with the cumulative incidence rate (0-74 age years old) of 22.08%. The cancer incidence and ASIRC were 303.39/100,000 and 150.31/100,000 in urban areas whereas in rural areas, they were 249.98/100,000 and 139.68/100,000, respectively. The cancer mortality in Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females), age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 85.06/100,000 and 115.65/100,000, and the cumulative incidence rate (0-74 age years old) was 12.94%. The cancer mortality and ASMRC were 181.86/100,000 and 80.86/100,000 in urban areas, whereas in rural areas, they were 177.83/100,000 and 94.40/100,000 respectively. Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreas cancer, encephaloma, lymphoma, female breast cancer and cervical cancer, were the most common cancers, accounting for 75% of all cancer cases in urban and rural areas. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia and lymphoma accounted for 80% of all cancer deaths. The cancer spectrum showed difference between urban and rural areas, males and females. The main cancers in rural areas were cancers of the stomach, followed by esophageal cancer, lung cancer, liver cancer and colorectal cancer, whereas the main cancer in urban areas was lung cancer, followed by liver cancer, gastric cancer and colorectal cancer. Conclusions: The coverage of cancer registration population has been increasing and data quality is improving. As the basis of cancer control program, cancer registry plays an important role in making anticancer strategy in medium and long term. As cancer burdens are different between urban and rural areas in China, prevention and control should be implemented based on practical situation. | Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Guanglin Li Lingyou Wu Jie He | 2013 | Chinese Journal of Cancer Research2013,25,1: | 202 |

| 15 | Targeted Mutagenesis in Zea mays Using TALENs and the CRISPR/Cas System显示文摘Transcription activator-like effector nucleases(TALENs) and clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated(Cas) systems have emerged as powerful tools for genome editing in a variety of species. Here, we report, for the first time, targeted mutagenesis in Zea mays using TALENs and the CRISPR/Cas system. We designed five TALENs targeting 4 genes, namely ZmPDS, ZmIPK1A, ZmIPK, ZmMRP4, and obtained targeting efficiencies of up to 23.1% in protoplasts, and about 13.3% to 39.1% of the transgenic plants were somatic mutations. Also, we constructed two gRNAs targeting the ZmIPK gene in maize protoplasts, at frequencies of 16.4% and 19.1%, respectively. In addition, the CRISPR/Cas system induced targeted mutations in Z. mays protoplasts with efficiencies(13.1%) similar to those obtained with TALENs(9.1%).

| 16 | Annual report on status of cancer in China,2010显示文摘Objective:Population-based cancer registration data in 2010 were collected,evaluated and analyzed by the National Central Cancer Registry(NCCR) of China.Cancer incident new cases and cancer deaths were estimated.Methods:There were 219 cancer registries submitted cancer incidence and death data in 2010.All data were checked and evaluated on basis of the criteria of data quality from NCCR.Total 145 registries' data were qualified and accepted for cancer statistics in 2010.Pooled data were stratified by urban/rural,area,sex,age group and cancer site.Cancer incident cases and deaths were estimated using age-specific rates and national population.The top ten common cancers in different groups,proportion and cumulative rate were also calculated.Chinese census in 2000 and Segi's population were used for age-standardized incidence/ mortality rates.Results:All 145 cancer registries(63 in urban and 82 in rural) covered a total of 158,403,248 population(92,433,739 in urban and 65,969,509 in rural areas).The estimates of new cancer incident cases and cancer deaths were 3,093,039 and 1,956,622 in 2010,respectively.The morphology verified cases(MV%) accounted for 67.11% and 2.99% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio(M/I) of 0.61.The crude incidence rate was 235.23/100,000(268.65/100,000 in males,200.21/100,000 in females),age-standardized incidence rates by Chinese standard population(ASIRC,2000) and by world standard population(ASIRW) were 184.58/100,000 and 181.49/100,000 with the cumulative incidence rate(0-74 years old) of 21.11%.The cancer incidence and ASIRC were 256.41/100,000 and 187.53/100,000 in urban areas whereas in rural areas,they were 213.71/100,000 and 181.10/100,000,respectively.The crude cancer mortality in China was 148.81/100,000(186.37/100,000 in males and 109.42/100,000 in females),age-standardized incidence rates by Chinese standard population(ASMRC,2000) and by world standard population(ASMRW) were 113.92/100,000 and 112.86/100,000,and the cumulative incidence rate(0-74 years old) was 12.78%.The cancer mortality and ASMRC were 156.14/100,000 and 109.21/100,000 in urban areas,whereas in rural areas,they were 141.35/100,000 and 119.00/100,000 respectively.Lung cancer,gastric cancer,colorectal cancer,liver cancer,esophageal cancer,pancreas cancer,encephaloma,lymphoma,female breast cancer and cervical cancer,were the most common cancers,accounting for 75% of all cancer cases in urban and rural areas.Lung cancer,gastric cancer,liver cancer,esophageal cancer,colorectal cancer,pancreatic cancer,breast cancer,encephaloma,leukemia and lymphoma accounted for 80% of all cancer deaths.Conclusions:The coverage of cancer registration population had a rapid increase and could reflect cancer burden in each area and population.As the basis of cancer control program,cancer registry plays an irreplaceable role in cancer epidemic surveillance,evaluation of cancer control programs and making anticancer strategy.China is facing serious cancer burden and prevention and control should be enhanced. | Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Hongmei Zeng Xiaonong Zou Jie He | 2014 | Chinese Journal of Cancer Research2014,26,1: | 198 |
| 17 | Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups. | Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He | 2018 | Chinese Journal of Cancer Research2018,30,6: | 132 |
| 18 | Antitumor activities of human autologous cytokineinduced killer(CIK)cells against hepatocellular carcinoma cells in vitro and in vivo显示文摘AIM: To characterize the anticancer function of cytokine-induced killer cells (CIK) and develop an adoptiveimmunotherapy for the patients with primary hepatocellularcarcinoma (HCC), we evaluated the proliferation rate,phenotype and the antitumor activity of human CIK cellsfrom healthy donors and HCC patients in vitro and in vivo.METHODS: Peripheral blood mononuclear cells (PBMC) fronhealthy donors and patients with primary HCC were incubatedin vitro and induced into ClK cells in the presence of variouscytokines such as interferon-gamma (IFN-γ), interleukin-1(IL-1), IL-2, and monoclonal antibody (mAb) against CD3.The phenotype and characterization of CIK cells wereidentified by flow cytometric analysis. The cytotoxicity of CIKcells was determined by 51 Cr release assay.RESULTS: The CIK cells were shown to be a heterogeneouspopulation with different cellular phenotypes. Thepercentage of CD3+/CD56+ positive cells, the dominanteffector cells, in total CIK cells from healthy donors andHCC patients, significantly increased from 0.1-0.13 % at day0 to 19.0-20.5 % at day 21 incubation, which suggested thatthe CD3+ CD56+ positive cells proliferated faster than othercell populations of CIK cells in the protocol used in thisstudy. After 28 day in vitro incubation, the ClK cells frompatients with HCC and healthy donors increased by morethan 300-fold and 500-fold in proliferation cell number,respectively. CIK cells originated from HCC patientspossessed a higher in vitro antitumor cytotoxic activity onautologous HCC cells than the autologous lymphokine-activated killer (LAK) cells and PBMC cells. In in vivoanimal experiment, CIK cells had stronger effects on theinhibition of tumor growth in Balb/c nude mice bearing BEL-7402-producing tumor than LAK cells (mean inhibitory rate,84.7 % vs 52.8 %, P < 0.05) or PBMC (mean inhibitoryrate, 84.7% vs37.1%, P<0.01).CONCLUSION: Autologous CIK cells are of highly efficientcytotoxic effector cells against primary hepatocellularcarcinoma cells and might serve as an alternative adoptivetherapeutic strategy for HCC patients. | Fu-Sheng Wang Ming-Xu Liu Bing Zhang Ming Shi Zhou-Yun Lei Wen-Bing Sun Qing-You Du Ju-Mei Chen,Division of Biological Engineering,Beijing Institute of Infectious Diseases,Beijing 100039,China Wen-Bing Sun,Department of Surgery,Beijing Hospital of Infectious Diseases,Beijing 100039,China | 2002 | World Journal of Gastroenterology2002,8,3: | 108 |

| 20 | Annual report on status of cancer in China, 2011显示文摘Objective: The National Central Cancer Registry(NCCR) collected population-based cancer registration data in 2011 from all cancer registries. National cancer incidence and mortality were compiled and cancer incident new cases and cancer deaths were estimated.Methods: In 2014, there were 234 cancer registries submitted cancer incidence and deaths occurred in 2011. All datasets were checked and evaluated based on the criteria of data quality from NCCR. Total 177 registries' data were qualified and compiled for cancer statistics in 2011. The pooled data were stratified by area(urban/rural), gender, age group(0, 1-4, 5-9, 10-14…85+) and cancer type. Cancer incident cases and deaths were estimated using age-specific rates and national population in 2011. All incidence and death rates are age-standardized to the 2000 Chinese standard population and Segi's population expressed per 100,000 persons.Results: All 177 cancer registries(77 in urban and 100 in rural areas) covered 175,310,169 populations(98,341,507 in urban and 76,968,662 in rural areas). The morphology verified cases(MV%) accounting for 70.14% and 2.44% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio of 0.63. The estimates of new cancer incident cases and cancer deaths were 3,372,175 and 2,113,048 in 2011, respectively. The incidence rate was 250.28/100,000(males 277.77/100,000, females 221.37/100,000), and the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 186.34/100,000 and 182.76/100,000 with the cumulative incidence rate(0-74 years old) of 21.20%. The cancer incidence and ASIRC in urban areas were 261.38/100,000 and 189.89/100,000 compared to 238.60/100,000 and 182.10/100,000 in rural areas, respectively. The cancer mortality was 156.83/100,000(194.88/100,000 in males and 116.81/100,000 in females), the age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 112.88/100,000 and 111.82/100,000, and the cumulative mortality rate(0-74 years old) was 12.69%. The cancer mortality and ASMRC were 154.37/100,000 and 108.20/100,000 in urban areas, and 159.42/100,000 and 117.97/100,000 in rural areas, respectively. Cancers of lung, female breast, stomach, liver, colon and rectum, esophageal, cervix, uterus, prostate and ovary were the most common cancers, accounting for about 75% of all cancer new cases. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer, female breast cancer, pancreatic cancer, brain tumor, cervical cancer and leukemia were the leading causes of cancer death, accounting for about 80% of all cancer deaths. The cancer incidence, mortality and spectrum showed difference between urban and rural areas, males and females.Conclusions: The coverage of cancer registration population had a greater increase than that in the last year. The data quality and representativeness are gradually improved. As the basic work of cancer prevention and control, cancer registry is playing an irreplaceable role. The disease burden of cancer is increasing, and the health department has to take effective measures to contain the increased cancer burden in China. | Wanqing Chen Rongshou Zheng Hongmei Zeng Siwei Zhang Jie He | 2015 | Chinese Journal of Cancer Research2015,27,1: | 431 |
