Introduction
Colorectal cancer (CRC) is one of the most commonly diagnosed types of cancer worldwide, ranking as the third most common neoplasia and the second leading cause of cancer-related deaths according to Global Cancer Statistics 2020 [1]. In Romania, CRC has the highest incidence rate, as reported by the Globocan platform in 2020, although the mortality rate follows global trends. The growing incidence of colorectal cancer poses a significant challenge to the global healthcare system [2].
Aims & Methods
Our aims are to assess and demonstrate the importance and value of a CRC screening program in early diagnosis among individuals aged 50 to 75 years in the southwestern of Oltenia, Romania. We prospectively enrolled apparently healthy individuals between 50 and 75 years old in a CRC prevention program at the University of Medicine and Pharmacy of Craiova, in the southwestern Oltenia region. The ongoing program started in November 2020. Exclusion criteria included individuals already enrolled in a screening program for CRC, with a personal history of colonic polyps, colorectal cancer, or inflammatory bowel diseases and individuals with a family history of inherited syndromes linked with CRC. Patients were identified based on the lists provided by participating general practitioners. All provided informed consent and completed a questionnaire regarding symptoms and family history of CRC. Based on their responses, patients were either offered a fecal immunochemical test (FIT) followed by colonoscopy in case of a positive result or were directly referred for colonoscopy. Those with negative results were instructed to repeat the test in two years.
Results
Until 24 April 2023 we enrolled 44,714 individuals (18,415 male, 41.18%). Of these, 38,610 (86.34%) received FITs, of whom 2,426 (6.28%) had a positive finding and 49 were directly referred for colonoscopy based on their questionnaire answers. We performed 1,262 colonoscopies, also having 1,004 refusals (41.38% of positive FITs) and 209 (8.61%) in waiting. Percentage of positive FIT tests correlated with older age (p<0.05). The chance of a positive colonoscopy finding correlated with the FIT value (p<0.05) and older age (p<0.05), while not being linked to either gender or provenance. We did not find lesions in 400 subjects (31.7% negative colonoscopies). In total, we found 2,092 significant lesions in 862 patients: 100 tumors and 1,992 polyps.
Conclusion
We provided here the first results of a large-scale CRC screening program in the Southwestern region of Romania, proving the importance of a coherent early detection strategy in the successful management of digestive malignancies. The high rate of colonoscopy refusals shows the need for an awareness campaign involving all medical and allied health personnel.
