Description
Marcelo Portes Rocha Martins and colleagues asked in 2026 whether a bowel tumor's side predicts outcome and whether a computer model can flag high-risk cases. Standard staging misses several factors that shape survival, so the team studied 71 operated patients from 2020 to 2024 and built a decision-tree model from their clinical and pathology details.
Left-sided tumors were more common and tied to alcohol use, pre-surgery chemoradiation, and higher deaths despite heavier treatment, while right-sided tumors favored women and vessel invasion. Positive surgical margins emerged as the strongest warning sign, giving surgeons a sharper tool for planning follow-up.
