Primitive Tumour Features

The stage of the primitive tumour is an important prognostic factor. Dukes C stage is associated with worse prognosis, with a 5-year survival in 25% of patients compared with 40% of patients with Dukes stage A and B. Scheele et al. [5, 24] emphasise that the stage of rectal cancer has a prognostic value only in the case of the presence of hepatic synchronous metastasis.

Rectal localisation in comparison to colonic seems to represents an unfavourable prognostic factor, even though this observation is not shared by all Authors in the literature [22, 24, 27].
