INTRODUCTION

Colorectal cancer (CRC) is a leading cause of mortality among adults. The objective of this study was to show results of the implementation of the colorectal cancer screening program (CRCSP) in the province of Neuquén, Argentina

METHODS

A retrospective study was conducted, with analysis of fecal occult blood test (FOBT) results in people aged 50 to 75 years, in public hospitals between 2015- 2019. Participation rate, FOBT results, colonoscopy (CC) performance in patients with positive FOBT and their findings, and positive predictive value (PPV) for detection of lesions and CRC were determined

RESULTS

A total of 11,189 FOBT were requested. The average participation was 6.52% of the target population, 24.6% of the participants had positive FOBT, and 24% of them had a CC performed. A significant lesion was found in 24.8% (adenomatous polyps 21.9%, cancer 2.9%), with a PPV for the detection of lesions of 34.3%. Furthermore, 7.4% had advanced adenomas, 17.6% of the patients repeated the FOBT after a negative result (second or third round), and 13.7% had a control CC performed after the finding of an adenomatous polyp

DISCUSSION

The CRCSP in Neuquén shows some indicators that need to be improved (coverage, conduction of CC) and others that are adequate (frequency of findings). In view of these difficulties, some more focused screening measures can be considered, such as use of CRC risk scales, bi-annual screening, etc.
