Determinants of Population-Based Cancer Screening Performance at Primary Healthcare Institutions in China

Willingness of healthcare providers to perform population-based cancer screening: a cross-sectional study in primary healthcare institutions in Tianjin, China

OBJECTIVE

To evaluate the willingness of healthcare providers to perform population-based screening in primary healthcare institutions in China.

METHODS

Healthcare providers of 262 primary healthcare institutions in Tianjin were invited to fill out a questionnaire consisting of demographic characteristics, workload, and knowledge of, attitude towards and willingness to perform breast, cervical and colorectal cancer screening. Willingness to screen was the primary outcome. Multilevel logistic regression models were conducted to analyse the determinants of healthcare providers' willingness to screen. ORs and 95% CIs were estimated.

RESULTS

A total of 554 healthcare providers from 244 institutions answered the questionnaire. 67.2%, 72.1% and 74.3% were willing to perform breast, cervical and colorectal cancer screening, respectively. A negative attitude towards screening was associated with a low willingness for cervical (OR=0.27; 95% CI 0.08, 0.94) and colorectal (OR=0.08; 95% CI 0.02, 0.30) cancer screening, while this was not statistically significant for breast cancer screening (OR=0.30; 95% CI 0.08, 1.12). For breast, cervical and colorectal cancer screening, 70.1%, 63.8% and 59.0% of healthcare providers reported a shortage of staff dedicated to screening. A perceived reasonable manpower allocation was a determinant of increased willingness to perform breast (OR=2.86; 95% CI 1.03, 7.88) and colorectal (OR=2.70; 95% CI 1.22, 5.99) cancer screening. However, this was not significant for cervical cancer screening (OR=1.76; 95% CI 0.74, 4.18).

CONCLUSIONS

In China, healthcare providers with a positive attitude towards screening have a stronger willingness to contribute to cancer screening, and therefore healthcare providers' attitude, recognition of the importance of screening and acceptable workload should be optimised to improve the uptake of cancer screening.

miR-127-3p Inhibits Breast Cancer Cell Behaviors via Targeting Benzodiazepine Receptor-Associated Protein 1 (BZRAP1)

microRNAs are key regulators of cell proliferation, apoptosis, and anti-cancer immune response. This study intends to evaluate miR-127-3p’s role in breast cancer cells (BC). After transfection, miR-156 and BZRAP1 expression was assessed by qRT-PCR and Western blotting along with analysis of cell proliferation and apoptosis by MTT and flow cytometry. Finally, an in vivo tumor model was established to verify miR-127-3p’s in vivo effect. Transfection of si-BZRAP1/miR-127-3p into MCF-7 cells reduced BZRAP1 expression, inhibited cell proliferation and promoted apoptosis. miR-127-3p is confirmed to target BZRAP1 and exerts tumor suppressor activity by inhibiting BZRAP1. miR-127-3p inhibited BC cell growth and promote apoptosis by targeting BZRAP1, indicating that it is expected to be a target for the treatment of BC. The significance of this study is to confirm that miR-127-3p may participate in tumor progression via BZRAP1, and may become a potential target for treating tumor. Further analysis of the pathogenesis of breast cancer and detection of miR-127-3p/BZRAP1 in BC has important application value in the treatment.
