RESUMO
Objective To analyze the clinical characteristics and survival prognosis of patients with AIDS-related malignant tumor. Methods We retrospectively analyzed the data of 354 patients with AIDS-related malignant tumor. Univariate analysis was conducted by Log rank test and multivariate analysis was conducted by Cox proportional risk regression model. Results The average age of the patients was 54.10±12.96 years old. The ratio of male to female patients was 2.1:1. The number of patients with AIDS complicated with lymphoma was the most, accounting for 28.25%. The 1-, 3- and 5-year survival rates were 78.48%, 62.13% and 55.31%, respectively. Univariate analysis showed that there were statistical differences in prognosis of patients with different types of malignant tumor, age, gender, medical insurance type, number of admissions after diagnosis of AIDS, average length of stay, radiotherapy or not, leaving hospital according to medical advice. Multivariate analysis showed that gender, number of admissions after diagnosis of AIDS, average length of stay, proportion of out-of-pocket and leaving hospital according to medical advice were independent risk factors affecting the survival and prognosis of patients. Conclusion AIDS is easily complicated with lymphoma, lung cancer and cervical cancer. The patients received insufficient anti-tumor courses in hospital.
RESUMO
Objective: To analyze the survival of patients with colon cancer who have special medical insurance in Chongqing, and to provide a reference for prognosis evaluation and prevention of colon cancer. Methods: A retrospective cohort study was conducted, and a total of 1 201 patients with colon cancer were enrolled. They were diagnosed and treated from January 2010 to December 2014 in Chongqing Malignant Tumor Treatment System. Follow-up was done by telephone, out-patient and in-patient review to understand the survival of all patients. The end point is the patient's death, and the end time of follow-up is December 31, 2018. The survival rate was calculated by Kaplan-Meier method. The log-rank test was used for the single factor analysis. The COX proportional hazards regression model was used for the multivariate analysis. Survival curves were plotted using GraphPad Prism 8.0 software. Results: The average diagnostic age of 1 201 patients with colon cancer was (64.98±12.71) years. Among them, there were male patients accounting for 58.20%, married patients for 93.78%, still smoking patients for 22.02%, still alcohol-drinking patients for 22.66%, TNM stage patients for 44.27%, and adenocarcinoma patients for 90.33%. The mean survival time of the patients was 84.82 months [95% confidence interval (CI): 82.34-87.30], and the 1-, 3and 5-year observed survival rates were 92.08%, 77.92% and 67.18%, respectively. Multivariate analysis showed that age, TNM staging, surgical treatment and histological differentiation were independent risk factors affecting survival and prognosis of colon cancer patients. Conclusion: The prognosis of patients with colon cancer is relatively good. There are many risk factors affecting the prognosis of patients with colon cancer. Surgical treatment and High degree of differentiation are the protective factors affecting the prognosis of patients.
RESUMO
Objective@#To investigate the demand and access to the cancer prevention and treatment knowledge and related factors among urban residents in China from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of general demographic characteristics, the demand and access to cancer prevention and treatment knowledge, and the influencing factors of the attitude. The Chi-square test was used to analyze the difference of the demand of the cancer prevention knowledge among different groups and the corresponding factors of the cancer prevention and treatment knowledge were analyzed by using the logistic regression model.@*Results@#The proportion of residents who need the cancer prevention and treatment knowledge was 79.5%. The demand rate of the inducement, symptom and diagnosis methods of cancer in the occupational population was highest, about 66.8%, 71.0% and 20.8%, respectively. The demand rate of treatment methods and cost in current cancer patients was the highest, about the 45.9% and 21.9%, respectively. The top three sources to acquire the cancer prevention and treatment knowledge were "broadcast or television" (69.5%), "books, newspapers, posters or brochures" (44.7%) and "family and friends" (33.8%). The multivariate analysis showed that compared with public institution personnel/civil servants, unmarried/cohabiting/divorced/widowed and others, annual household income less than 20 000 CNY, from the eastern region, people without cancer diagnosis and people with self-assessment of cancer risk, the demand rate of cancer prevention and treatment knowledge was higher in enterprise personnel/workers, married, annual household income between 60 000 CNY and 150 000 CNY, from the central region, people with cancer and people with unclear cancer risk (all P values <0.05).@*Conclusion@#There was a high demand for the cancer prevention and treatment knowledge among urban residents in China from 2015 to 2017. The main access to the knowledge is from the radio or television. The occupation, marital status, annual household income, residential region, health status and risk of disease were the main factors of the demand of the cancer prevention and treatment knowledge.
RESUMO
Objective@#To understand the health literacy of the cancer prevention and treatment among urban residents of China, and explore the related factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The health literacy of the cancer prevention, early discovery, early diagnosis, early treatment and the demands of cancer prevention and treatment knowledge was analyzed. The level of health literacy among different groups were calculated and compared. The binary logistic regression model was used to analyze the influencing factors of the health literacy of the cancer prevention and treatment.@*Results@#The level of health literacy of the cancer prevention and treatment was 56.97% among all study population; in each group it was 55.01% for community residents, 59.08% for cancer risk assessment/screening population, 61.99% for cancer patients and 57.31% for occupational population, respectively (P<0.001). The level of health literacy of the cancer prevention and treatment of residents aged 50 to 69 years old, other occupational groups, unmarried, the central and western region residents and the group with unclear self-assessment of cancer risk was significantly lower than that of residents younger than 40 years old, personnel of public institutions/civil servants, married, the eastern region residents and the group whose self-assessment without cancer risk (P<0.05) . The level of health literacy of cancer prevention and treatment of females, people who went to high school or over, cancer risk assessment/screening population, cancer patients and occupational population was significantly higher than that of males, people who had an education level of primary school or below and community residents (P<0.05) .@*Conclusion@#The health literacy of the cancer prevention and treatment of urban residents in China was relatively high, but there was still room for improvement. Gender, age, educational level, occupation, region, marital status, self-assessment of cancer risk, and type of respondents were the key influencing factors of the health literacy of the cancer prevention and treatment. Male, 50-69 years old, lower educational level, central and western regions, unclear cancer risk self-assessment, and without specific environmental exposure to cancer prevention and treatment knowledge or related risk factors were the characteristics of the key intervention group of the health literacy of the cancer prevention and treatment.
RESUMO
Objective@#To understand the consciousness of the cancer early treatment and its demographic and socioeconomic factors.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China (CanSPUC) from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The questionnaire collected personal information, the consciousness of the cancer early treatment and relevant factors. The Chi square test was used to compare the difference between the consciousness of the cancer early treatment and relevant factors among the four groups. The logistic regression model was used to analyze the influencing factors related to the consciousness of the cancer early treatment.@*Results@#With the assumption of being diagnosed as precancer or cancer, 89.97% of community residents, 91.84% of cancer risk assessment/screening population, 93.00% of cancer patients and 91.52% of occupational population would accept active treatments (P<0.001). If the immediate family members were diagnosed as precancer or cancer, people who would encourage their family members to receive early treatment in the four groups accounted for 91.96%, 91.94%, 92.44% and 91.55%, respectively (P<0.001). The company employees, annual household income with 40 000 yuan and more and other three groups had a relatively better consciousness of the cancer early treatment (P<0.05). Male, widowed, unemployed and from the central and western regions had a relatively worse consciousness of the cancer early treatment (P<0.05).@*Conclusion@#Residents in urban China participants had a good consciousness of the cancer early treatment. The marital status, occupation, annual household income and residential regions were major factors related to the consciousness of the cancer early treatment.
RESUMO
Objective@#To understand the consciousness of the cancer early diagnosis among urban residents and identify the related factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The general demographic characteristics, the consciousness of the cancer early diagnosis (whether people would have a willingness or encourage their relatives/friends to confirm the abnormal results once which were detected from the physical examination) and other information were collected by using the self-designed questionnaire. The non-conditional logistic regression model was used to identify the relateol factors related to the consciousness of the cancer early diagnosis.@*Results@#As for residents with abnormal result from the physical examination, 89.29% (28 802) of residents would choose to seek medical treatment for further diagnosis. If their relatives/friends had abnormal results from the physical examination, 89.55% (28 886) of residents would encourage their relatives/friends to confirm the diagnosis in time. The non-conditional logistic regression model analysis showed that compared with the public institution staff/civil servants, annual household income less than 20 000 CNY, the western region and the cancer risk assessment/screening intervention population, the company staff, annual household income about 40 000 CNY and more, and the residents from the middle and eastern region had a stronger consciousness to seek further diagnosis; while the unemployed residents and community residents were less likely to seek further diagnosis (P<0.05).@*Conclusions@#From 2015 to 2017, the Chinese urban residents had a good consciousness of the cancer early diagnosis. Occupation, annual household income, residential region and population group were related to the consciousness of the cancer early diagnosis.

Objective@#To understand the consciousness of the cancer early detection among urban residents and identify the influencing factors from 2015 to 2017.@*Methods@#A cross-sectional survey was conducted in 16 provinces covered by the Cancer Screening Program in Urban China from 2015 to 2017. A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. Self-designed questionnaires were used to collect population, socioeconomic indicators, self-cancer risk assessment, regular participation in physical examination and other information. The multivariate logistic regression model was used to identify the factors of people who had not regularly participated in the regular physical examination in the past five years.@*Results@#The self-assessment results of 32 357 residents showed that there were 27.54% (8 882) of total study population with self-reported cancer risk, 45.48% (14 671) without cancer risk and 26.98% (8 704) with unclear judgement on their own cancer risk. Among population with cancer risk, 79.84% (7 091) considered physical examination accounted. In the past five years, there were 21 105 (65.43%) residents participated in regular physical examination and 11 148 (34.56%) participated in non-scheduled one, respectively. The multivariate logistic regression analysis showed that compared with unmarried and western region residents, divorced, middle and eastern region residents had a stronger consciousness to participate in the regular physical examination (P<0.05). Compare with residents with annual household income less than 20 000 CNY in 2014, cancer risk assessment/screening intervention population, and self-assessment with cancer risk, residents with annual household income between 20 000 CNY and 59 000 CNY in 2014, occupational population, community residents, cancer patients, self-reported cancer-free risk, and self-assessment with unclear judgement of cancer risk were less likely to participate in the regular physical examination (all P values <0.05).@*Conclusion@#From 2015 to 2017, the Chinese urban residents had a acceptable consciousness of the cancer early detection. The marital status, annual household income, population group and self-assessment of cancer risk were related to the consciousness of the cancer early detection of people who had not participated in the regular physical examination in the past five years.

A total of 32 257 local residents aged ≥18 years old who could understand the investigation procedure were included in the study by using the cluster sampling method and convenient sampling method. All local residents were categorized into four groups, which contained 15 524 community residents, 8 016 cancer risk assessment/screening population, 2 289 cancer patients and 6 428 occupational population, respectively. The self-designed questionnaire was used to collect the information of demographic characteristics and cancer prevention consciousness focusing on nine common risk factors, including smoking, alcohol, fiber food, food in hot temperature or pickled food, chewing betel nut, helicobacter pylori, moldy food, hepatitis B infection, estrogen, and exercise. The logistic regression model was adopted to identify the influencing factors.@*Results@#The overall health literacy of the cancer prevention consciousness was 77.4% (24 980 participants), with 77.4% (12 018 participants), 79.9% (6 406 participants), 77.2% (1 766 participants) and 74.5% (4 709 participants) in each group (P<0.001). The correct response rates for nine risk factors ranged from 55.2% to 93.0%. The multivariate logistic regression analysis showed that compared with community residents, people with primary school level education or below, and the number of people living together in the family <3, the cancer risk assessment/screening intervention population, cancer patients, those with junior high school level educationor above and the number of people living in the family ≥3 had better health literacy of the cancer prevention consciousness (all P values <0.05). Compared with females, 39 years old and below, government-affiliated institutions or civil servants, from the eastern region, males, older than 40 years, company or enterprise employees, and from the middle or western region had worse health literacy of the cancer prevention consciousness (all P values <0.05).@*Conclusion@#The health literacy of the cancer prevention consciousness in Chinese urban residents should be improved. The cancer screening intervention, gender, age, education, occupation, the number of people co-living in the family, and residential region were associated with the health literacy of the cancer prevention consciousness.
RESUMO
Objective:To investigate the survival prognosis of patients with primary liver cancer and its influencing factors.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 3 106 patients with primary liver cancer who had health insurance for special illness in the Chongqing Malignant Tumor Treatment System from January 2000 to August 2018 were collected. There were 2 559 males and 547 females, aged (60±13)years, with a range from 19 to 95 years. Observation indicators: (1) demographic characteristics; (2) clinical treatment and pathological examination; (3) follow-up and survival; (4) analysis of prognostic factors. Follow-up using telephone interview, outpatient or inpatient reexamination was preformed to detect survival of patients. Follow-up was done once every 3 months within the first year and once a year thereafter up to December 2018. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represent as M (range). Count data were expressed as absolute numbers or percentages. Survival analysis was done after excluding missing data of follow-up. The survival rate was calculated and survival curve was drawn by Kaplan-Meier method. The prognostic factors were analyzed after excluding missing data of follow-up, pathological type, and TNM staging. The log-rank test was used for univariate analysis, and COX proportional hazard model was used for multivariate analysis. Results:(1) Demographic characteristics: of the 3 106 patients with primary liver cancer, the number of males and females (gender), cases with age < 30 years, from 30 to 44 years, from 45 to 59 years, from 60 to 74 years, ≥75 years, cases of Han nationality or other ethnic groups, cases being married or other status (marital status), cases with occupation as enterprise unit staff and (or) workers, public institution personnel and (or) civil servants, freelancers and (or) self-employed entrepreneurs, unemployed, company staff, and other professionals were 2 559, 547, 35, 362, 1 131, 1 163, 415, 3 053, 53, 2 896, 210, 880, 342, 130, 101, 124, and 1 529, respectively. (2) Clinical treatment and pathological examination: of the 3 106 patients with primary liver cancer, cases with hospitalization time < 10 days, from 10 to 19 days, from 20 to 29 days, ≥30 days, cases without surgery or with surgery, cases with hepatocellular carcinoma, cholangiocarcinoma, hybrid type and other pathological types, cases of stage Ⅰ, Ⅱ, Ⅲ, Ⅳ of TNM staging were respectively 771, 1 312, 661, 362, 915, 2 191, 836, 63, 24, 29, 28, 90, 624. There were 2 183 out of 3 106 patients without pathological data and 2 335 without TNM staging data. (3) Follow-up and survival: of the 3 106 patients with primary liver cancer, 2 561 were followed up for 3.0-96.0 months, with a median follow-up time of 27.6 months. The 2 561 patients had survived for 1.0-96.0 months, with a median survival time of 24.7 months. The 1-, 3-, 5-year survival rates were 63.2%, 42.3%, 29.5%, respectively. (4) Analysis of prognostic factors: results of univariate analysis showed that age, marital status, occupation, hospitalization time, surgical treatment, pathological types, and TNM staging were related factors for prognosis of patients ( χ2=31.820, 6.752, 39.100, 120.889, 226.700, 10.452, 48.602, P<0.05). Results of multivariate analysis showed that being married, hospitalization time no less than 30 days, surgical treatment were independent protective factors for prognosis ( hazard ratio=1.463, 0.572, 0.575, 95% confidence interval: 1.044-2.049, 0.413-0.793, 0.438-0.755, P<0.05), stage Ⅲ and Ⅳ of TNM staging were independent risk factors for prognosis of patients ( hazard ratio=3.941, 5.036, 95% confidence interval: 1.687-9.211, 2.237-11.335, P<0.05). Conclusions:Patients with primary liver cancer have poor prognosis. Being married, hospitalization time no less than 30 days, and surgical treatment are independent protective factors for prognosis, stage Ⅲ and Ⅳ of TNM staging are independent risk factors for prognosis.
RESUMO
Objective To estimate the cancer incidence and mortality in Chongqing in 2014.Methods On basis of the methods and criteria of data quality control made by NCCR,authors compiled and summarized the 2014 tumor registration data reported by 11 registries in Chongqing.The datas which were stratified by area (urban/rural),gender,age and cancer type,incidence and mortality were calculated combined with national population.Results All 11 cancer registries reported 24 506 new cancer cases (14 610 were male and 9 896 were female)in 2014.The crude incidence in Chongqing was 244.66/105 (male was 289.01/105,female was 199.47/105).Sex ratio was 1.45:1.00,male was significantly higher than female.The incidence of lung cancer,colorectum,liver,esophagus,breast,stomach were the top six tumor.The incidence rate of all age groups in 2014 increased with age,the incidence rate increased from 40-44 years old group,and reached the highest incidence rate in the 80-84 years old group.Conclusion The data quality and representativeness in Chongqing tumor registration are gradually improved.Cancer registration as the basis of cancer prevention and control work,play an irreplaceable role.
