[The ultrastructural factors of the individual prognosis in rectal cancer in patients following radical surgical treatment].

Multifactorial analysis of the prognostic diagnosis of 39 main clinical, morphological and ultrastructural traits in 109 patients with rectum carcinoma is performed on the basis of computer EC-1045/230 program and algorithmic complex. The optimal complex of the traits is established possessing the maximum information value for prognosis of the 2-, 3- and 5-year survival of patients with this tumour. Three rules are formed for the individual prognosis of a favourable and unfavourable issue of the disease after the radical surgery. The value (in %) of these rules for the prognosis was determined: 79,86 and 92% for the 2-, 3- and 5-year survival, respectively. This is the precision with which one or another prognosis can be predicted.
