ABSTRACT

BACKGROUND@#Prospective analyses have yet to identify a consistent relationship between sleep duration and the incidence of gastrointestinal (GI) cancers. The effect of changes in sleep duration on GI cancer incidence has scarcely been studied. Therefore, we aimed to examine the association between baseline sleep duration and annual changes in sleep duration and GI cancer risk in a large population-based cohort study.@*METHODS@#A total of 123,495 participants with baseline information and 83,511 participants with annual changes in sleep duration information were prospectively observed from 2006 to 2015 for cancer incidence. Cox proportional-hazards models were used to calculate hazard ratios (HRs) and their confidence intervals (CIs) for GI cancers according to sleep duration and annual changes in sleep duration.@*RESULTS@#In baseline sleep duration analyses, short sleep duration (≤5 h) was significantly associated with a lower risk of GI cancer in females (HR: 0.31, 95% CI: 0.10-0.90), and a linear relationship between baseline sleep duration and GI cancer was observed (P = 0.010), especially in males and in the >50-year-old group. In the annual changes in sleep duration analyses, with stable category (0 to -15 min/year) as the control group, decreased sleep duration (≤-15 min/year) was significantly associated with the development of GI cancer (HR: 1.29; 95% CI: 1.04-1.61), especially in the >50-year-old group (HR: 1.32; 95% CI: 1.01-1.71), and increased sleep duration (>0 min/year) was significantly associated with GI cancer in females (HR: 2.89; 95% CI: 1.14-7.30).@*CONCLUSIONS@#Both sleep duration and annual changes in sleep duration were associated with the incidence of GI cancer.

ABSTRACT

BACKGROUND@#Cancer is one of the leading causes of death globally, but its burden is not uniform. GLOBOCAN 2020 has newly updated the estimates of cancer burden. This study summarizes the most recent changing profiles of cancer burden worldwide and in China and compares the cancer data of China with those of other regions.@*METHODS@#We conducted a descriptive secondary analysis of the GLOBOCAN 2020 data. To depict the changing global profile of the leading cancer types in 2020 compared with 2018, we extracted the numbers of cases and deaths in 2018 from GLOBOCAN 2018. We also obtained cancer incidence and mortality from the 2015 National Cancer Registry Report in China when sorting the leading cancer types by new cases and deaths. For the leading cancer types according to sex in China, we summarized the estimated numbers of incidence and mortality, and calculated China's percentage of the global new cases and deaths.@*RESULTS@#Breast cancer displaced lung cancer to become the most leading diagnosed cancer worldwide in 2020. Lung, liver, stomach, breast, and colon cancers were the top five leading causes of cancer-related death, among which liver cancer changed from the third-highest cancer mortality in 2018 to the second-highest in 2020. China accounted for 24% of newly diagnosed cases and 30% of the cancer-related deaths worldwide in 2020. Among the 185 countries included in the database, China's age-standardized incidence rate (204.8 per 100,000) ranked 65th and the age-standardized mortality rate (129.4 per 100,000) ranked 13th. The two rates were above the global average. Lung cancer remained the most common cancer type and the leading cause of cancer death in China. However, breast cancer became the most frequent cancer type among women if the incidence was stratified by sex. Incidences of colorectal cancer and breast cancer increased rapidly. The leading causes of cancer death varied minimally in ranking from 2015 to 2020 in China. Gastrointestinal cancers, including stomach, colorectal, liver, and esophageal cancers, contributed to a massive burden of cancer for both sexes.@*CONCLUSIONS@#The burden of breast cancer is increasing globally. China is undergoing cancer transition with an increasing burden of lung cancer, gastrointestinal cancer, and breast cancers. The mortality rate of cancer in China is high. Comprehensive strategies are urgently needed to target China's changing profiles of the cancer burden.

ABSTRACT

Osteoprotegerin (OPG), secreted by osteoblasts, is a marker of bone turnover. OPG can inhibit osteoclastic differentiation by binding receptor activator of nuclear factor-κB ligand (RANKL). In this study, we found that rutaecarpine (RUT) had the up-regulating OPG activity, and it could significantly increase OPG protein levels in both mouse embryonic osteogenic precursor MC3T3-E1 and human osteosarcoma U-2OS cells. Osteoblastogenic differentiation calcified nodules staining results showed that RUT significantly promoted the osteogenic differentiation of MC3T3-E1 cells. Osteoclastic differentiation tartrate resistant acid phosphatase (TRAP) staining results showed that RUT obviously inhibited the osteoclast differentiation of mouse macrophages RAW264.7 induced by RANKL. In vivo studies showed that low-dose RUT group (5 mg·kg-1·day-1) and high-dose RUT group (45 mg·kg-1·day-1) treatments for 3 months significantly increased bone density in ovariectomized (OVX) rats; calcein double labeling experiment and toluidine blue staining results indicated that low-dose RUT group promoted bone formation and decreased bone loss in vivo; immunohistochemistry results showed that low-dose RUT group increased the expression of OPG in rat femur. All animal procedures were performed in accordance with the regulations of the Institutional Animal Care and Use Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences. In summary, this study demonstrated that RUT could up-regulate OPG expression and had promoting osteoblastic differentiation and inhibiting osteoclastic differentiation effects in vitro and in vivo.

ABSTRACT

BACKGROUND@#Early detection of gastric cancer (GC) has been the topic of major efforts in China. This study aimed to explore the risk factors associated with GC and to provide evidence for the selection of a high-risk population of GC.@*METHODS@#Based on the cancer screening cohort of the National Cancer Screening Program in Urban China, GC patients diagnosed by endoscopy and pathological examinations constituted the case group, and controls were 1:3 matched by sex and age (±5 years) individually. The variables were selected by univariable analysis of factors such as body mass index (BMI), dietary habits, lifestyle, stomach disease history, and family history of GC; and multivariable logistic regression was used to analyze the influencing factors of GC and to calculate the odds ratio (OR) of related factors and its 95% confidence interval (CI).@*RESULTS@#A total of 215 GC cases and 645 matched healthy controls were included in the final analysis, with a median age of 61 years for the case and control groups. Overall analysis showed that high educational level (above primary school) (OR = 0.362, 95% CI = 0.219-0.599, P < 0.001), overweight/obesity (BMI ≥24 kg/m2; OR = 0.489, 95% CI = 0.329-0.726, P < 0.001), cigarette smoking (OR = 3.069, 95% CI = 1.700-5.540, P < 0.001), alcohol consumption (OR = 1.661, 95% CI = 1.028-2.683, P = 0.038), history of stomach disease (OR = 6.917, 95% CI = 4.594-10.416, P < 0.001), and family history of GC in first-degree relatives (OR = 4.291, 95% CI = 1.661-11.084, P = 0.003) were significantly correlated with the occurrence of GC. Subgroup analyses by age and gender indicated that GC risk was still increased in the presence of a history of stomach disease. A history of chronic gastritis, gastric ulcer, or gastric polyposis was positively associated with GC, with adjusted ORs of 4.155 (95% CI = 2.711-6.368), 1.839 (95% CI = 1.028-3.288), and 2.752 (95% CI = 1.197-6.326).@*CONCLUSIONS@#Subjects who smoke, drink, with history of stomach disease and family history of GC in first-degree relatives are the high-risk populations for GC. Therefore, attention should be paid to these subjects for GC screening.

ABSTRACT

Objective:To use autoregressive integrated moving average (ARIMA) model for predicting the mortality of cardiovascular diseases in residents in Yushui District, Jiangxi Province, and to provide basis for developing the prevention and control strategies as well as to promote the continuous optimization of chronic disease prevention and treatment demonstration area. Methods:Based on the cardiovascular death monitoring data of residents in Yushui District, Jiangxi Province from 2014 to 2018, Econometrics View 9.0 software was used to construct the ARIMA seasonal adjustment model to predict the monthly cardiovascular death in this area. Results:The monthly death rate of cardiovascular diseases in Yushui showed a long-term rising trend, with an apparent seasonal pattern (a peak of cardiovascular death from December to January each year). After the original sequence was subjected to first-order difference and first-order seasonal difference, the difference sequence showed good stationarity (P<0.05). All the theoretical models were listed and their model parameters were calculated respectively. After statistical test (P<0.05), 7 alternative models for seasonal adjustment of ARIMA were selected. Among them, ARIMA(1,1,1)(1,1,1)12 is the optimal model selected in this study (R2=0.749, Adjustment R2=0.724, AIC=8.454, SC=8.633, HQ=8.515).And its residual sequence was tested by white noise test (P>0.05), indicating that the prediction effect was good. Conclusion:ARIMA(1,1,1)(1,1,1) 12 model can accurately simulate the long-term trend and seasonal pattern of cardiovascular disease death in Yushui, and make a scientific prediction of the trend and monthly distribution of cardiovascular disease death in the next three years.

ABSTRACT

In China, the malignant tumor with the highest incidence and motality is lung cancer (LC). As screening and early detection and treatment are effective in reducing LC mortality, formulating a guideline in line with China′s national conditions for the screening and early detection and treatment of LC will greatly promote the homogeneity and accuracy of LC screening, and result in an improvement of the effectiveness of LC screening. Commissioned and directed by the Disease Prevention and Control Bureau of the National Health Commission of the People′s Republic of China, the guidline was initiated by the National Cancer Center of China and formulated with joint effort by experts from different disciplines. Following the principles and methods in WHO Handbook for Guideline Development, the guidline integrates the latest development in LC screening and early diagnosis and treatment worldwide while fully considering China′s national conditions and practical experience in LC screening. It provides detailed evidence-based recommendations for different aspects of LC screening, such as the targeted population, the technologies and the procedures, to regulate the practices of LC screening and early diagnosis and treatment and enhance the effectiveness of the prevention and control of LC in China.

ABSTRACT

OBJECTIVES@#To study the effect of glucose metabolism disorders on the short-term prognosis in neonates with asphyxia.@*METHODS@#A retrospective analysis was performed on the medical data of the neonates with asphyxia who were admitted to 52 hospitals in Hubei Province of China from January to December, 2018 and had blood glucose data within 12 hours after birth. Their blood glucose data at 1, 2, 6, and 12 hours after birth (with an allowable time error of 0.5 hour) were recorded. According to the presence or absence of brain injury and/or death during hospitalization, the neonates were divided into a poor prognosis group with 693 neonates and a good prognosis group with 779 neonates. The two groups were compared in the incidence of glucose metabolism disorders within 12 hours after birth and short-term prognosis.@*RESULTS@#Compared with the good prognosis group, the poor prognosis group had a significantly higher proportion of neonates from secondary hospitals (48.5% vs 42.6%, @*CONCLUSIONS@#Recurrent hyperglycemia in neonates with asphyxia may suggest poor short-term prognosis, and it is necessary to strengthen the early monitoring and management of the nervous system in such neonates.

ABSTRACT

The health literacy refers to the ability of individuals to acquire and understand basic health information and services and use them to make the right decisions to maintain and promote their health. Health literacy data focusing on cancer prevention and control was limited in China. In order to understand the health literacy and awareness of cancer risk factors and the cancer screening, early diagnosis and treatment in Chinese urban residents and compare the effect of different stages of the cancer intervention, the Cancer Screening Program in Urban China (CanSPUC) program, supported by the National Key Public Health Program, conducted a survey on the health literacy of the cancer prevention and treatment among urban residents in 16 provinces nationwide from 2015 to 2017. Four subgroups were designed in this survey, including (1) general population who have never participated in any cancer screening programs at a community-level; (2) individuals who have previously attended the CanSPUC program for cancer risk assessment or screening intervention; (3) cancer patients who were receiving treatment in local hospitals; (4) a special group from employees of government and public institutions (non-health system), state-owned enterprises and private enterprises (to have better understand on the impact of socioeconomic factors). The self-designed questionnaire covered six parts, including basic information, consciousness of common risk factors to cancer, awareness of early detection, awareness of early diagnosis, awareness of early treatment, and the needs and approaches for knowledge of cancer prevention and treatment. A total of 32 257 individuals were included in the final analyses. This paper landscaped the overall design of the survey, including participants, domains of the instrument, quality control, basic characteristics of the included individuals. These descriptions are applicable to each individual report of the current special issue of "Health Literacy of Cancer Control in Urban China" and future reports, in which more detailed results are and will be reported. The findings of this survey could provide some useful implications for similar researches in the future.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Objective@#To understand the health literacy and relevant factors of cancer prevention consciousness in Chinese urban residents 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 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.

ABSTRACT

BACKGROUND@#Due to development of magnetic resonance-based functional imaging, it is easier to detect micro-structural alterations of tumor tissues. The aim of this study was to conduct a preliminary evaluation of the correlation of non-Gaussian diffusion kurtosis imaging (DKI) parameters with expression of molecular markers (epidermal growth factor receptor [EGFR]; anaplastic lymphoma kinase [ALK]; Ki-67 protein) in patients with advanced lung adenocarcinoma, using routine diffusion-weighted imaging as the reference standard.@*METHODS@#Data from patients with primary lung adenocarcinoma diagnosed at Cancer Hospital, Chinese Academy of Medical Sciences (CHCAMS) from 2016 to 2019 were collected for retrospective analysis. The pathologic and magnetic resonance imaging data of 96 patients who met the inclusion criteria were included in this study. Specifically, the Kapp and Dapp parameters measured from the DKI model; apparent diffusion coefficient (ADC) value from the diffusion-weighted imaging model; and the EGFR, ALK, and Ki-67 biomarkers detected by immunohistochemistry and/or molecular biology techniques after biopsy or surgery were evaluated. The relations between quantitative parameters (ADC, Kapp, Dapp) and pathologic outcomes (EGFR, ALK, and Ki-67 expression) were analyzed by Spearman correlation test.@*RESULTS@#Of the 96 lung adenocarcinoma lesions (from 96 patients), the number of EGFR- and ALK-positive and high Ki-67 expressing lesions were 53, 12, and 83, respectively. The Kapp values were significantly higher among patients with EGFR-positive mutations (0.81 ± 0.12 vs. 0.66 ± 0.10, t = 6.41, P < 0.001), ALK rearrangement-negative (0.76 ± 0.12 vs. 0.60 ± 0.15, t = 4.09, P < 0.001), and high Ki-67 proliferative index (PI) (0.76 ± 0.12 vs. 0.58 ± 0.13, t = 4.88, P < 0.001). The Dapp values were significantly lower among patients with high Ki-67 PI (3.19 ± 0.69 μm/ms vs. 4.20 ± 0.83 μm/ms, t = 4.80, P < 0.001) and EGFR-positive mutations (3.11 ± 0.73 μm/ms vs. 3.59 ± 0.77 μm/ms, t = 3.12, P = 0.002). The differences in mean Dapp (3.73 ± 1.26 μm/ms vs. 3.26 ± 0.68 μm/ms, t = 1.96, P = 0.053) or ADC values ([1.34 ± 0.81] × 10 mm/s vs. [1.33 ± 0.41] × 10 mm/s, t = 0.07, P = 0.941) between the groups with or without ALK rearrangements were not statistically significant. The ADC values were significantly lower among patients with EGFR-positive mutation ([1.19 ± 0.37] × 10 mm/s vs. [1.50 ± 0.53] × 10 mm/s, t = 3.38, P = 0.001) and high Ki-67 PI ([1.28 ± 0.39] × 10 mm/s vs. [1.67 ± 0.77] × 10 mm/s, t = 2.88, P = 0.005). Kapp was strongly positively correlated with EGFR mutations (r = 0.844, P = 0.008), strongly positively correlated with Ki-67 PI (r = 0.882, P = 0.001), and strongly negatively correlated with ALK rearrangements (r = -0.772, P = 0.001). Dapp was moderately correlated with EGFR mutations (r = -0.650, P = 0.024) or Ki-67 PI (r = -0.734, P = 0.012). ADC was moderately correlated with Ki-67 PI (r = -0.679, P = 0.033).@*CONCLUSIONS@#The Kapp value of DKI parameters was strongly correlated with different expression of EGFR, ALK, and Ki-67 in advanced lung adenocarcinoma. The results potentially indicate a surrogate measure of the status of different molecular markers assessed by non-invasive imaging tools.
