Changes in the cellular proliferation of the healthy mucosa in patients with colorectal cancer
1994
AIM: To analyze differences in the proliferative pattern of normal mucosa between patients with colorectal cancer and healthy subjects. PATIENTS AND METHODS: By using flow cytometry we examined the proliferative pattern (Proliferative Index and S-Phase) in samples of normal mucosa from 34 patients operated on for colorectal cancer at our hospital and from 14 healthy subjects as a control group. RESULTS: All examined samples were diploid. The Proliferative Index and S-Phase in the Cancer Group were significantly higher than in the Control Group (16.7 +/- 5.9 vs 11.4 +/- 4, p < 0.003, and 11.9 +/- 3.9 us 6.6 +/- 3 p < 0.0004). CONCLUSIONS: These findings provide evidence for an altered proliferative pattern in the healthy colonic mucosa of patients with colorectal cancer.
