AI Article Synopsis
- Approximately 147,000 Americans are expected to be diagnosed with colorectal carcinoma this year, which accounts for 15% of all cancers and 12% of cancer deaths.
- Screening methods like fecal occult blood tests and sigmoidoscopy can help detect the disease early or even prevent it by removing polyps.
- While general and targeted screening is promising for reducing cancer incidence and mortality, the cost-effectiveness and definitive benefits of these screenings are still being evaluated.
Article Abstract
Colorectal carcinoma will occur in some 147,000 Americans this year. This disease accounts for 15% of all cancers and 12% of all cancer deaths. Screening for colorectal carcinoma may allow the disease process to be found earlier and, in some situations such as when polyps are found and removed, may even prevent the disease. The two main modalities of screening are fecal occult blood tests and sigmoidoscopy. By general screening of asymptomatic patients as well as by selective screening of those at high risk, there is hope that the incidence and mortality of this cancer will diminish. Absolute confirmation of this benefit is still lacking, making the evaluation of the cost-effectiveness of this screening somewhat questionable. Current educational efforts are designed to increase compliance and to help solve some of these unanswered questions.

Stereocaulon alpinum has been found to have potential pharmaceutical properties due to the presence of secondary metabolites such as usnic acid, atranorin, and lobaric acid (LA) which have anticancer activity. On the other hand, the effect of LA on the stemness potential of colorectal cancer (CRC) cells remains unexplored, and has not yet been thoroughly investigated. In this study, we examined the inhibitory activity of LA from Stereocaulon alpinum against the stemness potential of CRC cells and investigated the possible underlying mechanisms.

About the authors: Seval Ulubay, PhD, Samsun Gazi State Hospital, Samsun, Türkiye.
Colorectal cancer can be diagnosed early with screening tests; therefore, patients' beliefs regarding colorectal cancer screening are closely related to clinical and pathological disease stages at the time of diagnosis. This study aimed to determine participation in colorectal cancer screening programs and health beliefs related to protection from colorectal cancer among patients aged 40-70 years and evaluate factors affecting their participation in such screening programs. This descriptive study was conducted in a state hospital in Türkiye between May 2021 and December 2021 with the participation of 1,016 patients.
