Retrospective Evaluation of Gastroscopic Findings in Colon Cancer Patients and Colonoscopic Findings in Gastric Cancer Patients

Objectives: The aim study is to detect gastroscopic lesions in colon cancer patients and colonoscopic lesions in gastric cancer patients.
Methods: This study is a single-center retrospective study. 101 colon cancer and 53 gastric cancer patients were included in the study. In colon cancer control group, 115 patients were selected who applied colonoscopy with no malignancy re-sult. And in gastric cancer control group, 112 patients were selected who applied gastroscopy with no malignancy result. Results: We observed colon cancer in 2 (%3,8) patients and totally 22 colon polyps in 13 (%24,5) patients from 53 gastric cancer patients. There was no colon cancer diagnosis and totally 36 colon polyps found in 27(%24,1) in control group (n=1l 2) patients. There was no statistically significance in both groups about the number and adenomatous polyps ratio (p>0.05). In colon cancer group (n=10l), 1 (%1) patient had severe dysplasia and 10(%9,9) patients had gastric polyp; but in control group (n=115), there was 1 (%0,8) mild dysplasia and 11(%9,6) gastric polyp. There was no statistically significance in both groups about the number and adenomatous of polyps.
Conclusion: We found no statistically significant difference between the groups. Prospective studies are needed for second primary cancer investigations.
