Real-World Utilization, Barriers, and Factors Associated With the Targeted Treatment of Metastatic Colorectal Cancer Patients in China: A Multi-Center, Hospital-Based Survey Study.

Objectives: To explore the utilization, barriers, and factors associated with the targeted treatment of Chinese metastatic colorectal cancer (mCRC) patients. Methods: A total of 1,688 mCRC patients from 19 hospitals in 14 cities were enrolled from March 2020 to March 2021 using stratified, multistage cluster sampling. The use of targeted therapy and any barriers patients experienced were collected. Logistic regression analyses were conducted to identify the factors associated with initiating targeted treatment. Results: About 51.6% of the patients initiated targeted therapy, of whom 44.5%, 20.2%, and 35.2% started first-, second-, and third-line treatment, respectively. The most reported barriers were high medical costs and a lack of belief in the efficacy of targeted therapy. Patients treated in the general hospital, diagnosed at an older age, less educated, and who had a lower family income, no medical insurance, poor health-related quality of life, metastasis outside the liver/lung or systemic metastasis, a shorter duration of mCRC were less likely to initiate targeted therapy. Conclusion: Reduced medical costs and interventional education to improve public awareness could facilitate the use of targeted treatment for mCRC.

Out-of-pocket medical expenditure and associated factors of advanced colorectal cancer in China: a multi-center cross-sectional study.

Background: Colorectal cancer (CRC) causes a substantial disease burden in China. Information on the medical expenditure of CRC patients is critical for decision-makers to allocate medical resources reasonably, however, relevant data is limited in China, especially advanced CRC. The aim of this survey was to quantify the out-of-pocket medical expenditure of advanced CRC and explore associated factors. Methods: A nation-wide, multi-center, cross-sectional survey was conducted from March 2020 to March 2021. Nineteen hospitals in seven geographical regions were selected by multi-stage stratified sampling. For each eligible CRC patient with stage III or IV disease in the selected hospitals, the socio-demographics, clinical information, and range of out-of-pocket medical expenditure data were collected based on patients' self-reporting or medical records. Multivariable logistic analysis was used to explore associated factors of medical expenditure. All statistical analyses were conducted using SAS 9.4. Results: The mean age of the 4,428 advanced CRC patients included was 59.5±11.6 years, 59.6% were male, and 80.1% of patients were in stage III or IV at the time of diagnosis. Besides, 57.2% of patients had an annual household income of less than 50,000 Chinese Yuan (CNY), 40.9% of patients had an out-of-pocket medical expenditure of 50,000-99,999 CNY. As for the affordability of medical expenditure, 33.2% could afford 50,000-99,999 CNY. Multivariate analysis showed that patients who were in the southern [odds ratio (OR): 1.63, 95% confidence interval (CI): 1.31-2.03] and southwestern (OR: 1.55, 95% CI: 1.25-1.93), were in stage III at the time of diagnosis (OR: 1.33, 95% CI: 1.13-1.57), visited three or more hospitals (OR: 1.26, 95% CI: 1.04-1.52), had sought cross-regional health care (OR: 1.60, 95% CI: 1.40-1.83), used genetic testing (OR: 1.26, 95% CI: 1.10-1.45) and targeted drugs (OR: 2.12, 95% CI: 1.79-2.51) had higher out-of-pocket medical expenditure. Conclusions: Patients with advanced CRC had a high out-of-pocket medical expenditure. It is necessary to strengthen the prevention and control of CRC to reduce the disease burden; also, it is critical to deepen the reform of the medical system, increase proportion of medical insurance reimbursement, and remove barriers to cross-regional health care.

The COmprehensive Score for financial Toxicity in China: Validation and Responsiveness.

CONTEXT: Financial toxicity is a priority concern faced by cancer patients and oncology providers. A validated instrument is important to measure this toxicity and improve health-related quality of life of patients. OBJECTIVES: To assess the validity and responsiveness of the Chinese version of the COmprehensive Score for financial Toxicity (COST) and to measure financial toxicity using the COST instrument in Chinese health care systems. METHODS: A longitudinal observational study was performed at three cancer centers from March 2017 to October 2018 for eligible patients. Construct validity was assessed by exploratory and confirmatory factor analysis. The convergent and discriminant validity was tested by examining the correlation coefficient. Responsiveness was tested using the standardized response mean and effect size. Associations between the financial toxicity and variables were assessed by multivariable linear analysis. RESULTS: There were 440 participants at baseline and 268 participants at 6-month follow up. A two-factor solution better represented the Chinese version of COST structure with good internal consistency and test-retest reliability. Convergent validity showed mild to moderate correlations between the domains of COST and the similar domains of Self-Perceived Burden Scale and Quality of Life Discriminant validity showed a low correlation between the COST and the subjective support of Social Support Rate Scale. Sensitivity to change at the sixth month showed effect sizes with global COST scores of 0.3. Multivariable analysis showed that age, household income, and health insurance were significantly associated with financial toxicity. CONCLUSIONS: The Chinese version of COST is a valid and clinically responsive instrument. The identified baseline variables can be used to provide evidence for a financial toxicity intervention study.

Lung cancer imaging methods in China from 2005 to 2014: A national, multicenter study.

BACKGROUND: The study was conducted to examine changes in diagnostic and staging imaging methods for lung cancer in China over a 10-year period and to determine the relationships between such changes and socioeconomic development. METHODS: This was a hospital-based, nationwide, multicenter retrospective study of primary lung cancer cases. The data were extracted from the 10-year primary lung cancer databases at eight tertiary hospitals from various geographic areas in China. The chi-squared test was used to assess the differences and the Cochran-Armitage trend test was used to estimate the trends of changes. RESULTS: A total of 7184 lung cancer cases were analyzed. Over the 10-year period, the utilization ratio of diagnostic imaging methods, such as chest computed tomography (CT) and chest magnetic resonance imaging (MRI), increased from 65.79% to 81.42% and from 0.73% to 1.96%, respectively, while the utilization ratio of chest X-ray declined from 50.15% to 30.93%. Staging imaging methods, such as positron emission tomography-CT, neck ultrasound, brain MRI, bone scintigraphy, and bone MRI increased from 0.73% to 9.29%, 22.95% to 47.92%, 8.77% to 40.71%, 42.40% to 62.22%, and 0.88% to 4.65%, respectively; abdominal ultrasound declined from 83.33% to 59.9%. These trends were more notable in less developed areas than in areas with substantial economic development. CONCLUSION: Overall, chest CT was the most common radiological diagnostic method for lung cancer in China. Imaging methods for lung cancer tend to be used in a diverse, rational, and regionally balanced manner.
