Fhit protein expression in colorectal carcinomas

The following trends were observed: the proportion of tumors with
reduced expression increased with decreasing differentiation
(χ^{2} = 5.76, *df* = 1,
*P* = 0.016); the proportion of tumors with
reduced expression increased in tumors with metastases (Dukes’ stage
C + D) compared with tumors without metastases (Dukes’
stage A + B; χ^{2} = 3.68,
*df* = 1, *P* = 0.055).
There was a lack of association of differentiation with Fhit expression
(*P* = 0.1204, Fisher’s exact test); and of
Dukes’ stage with Fhit expression (*P* = 0.4512, Fisher’s exact test).
