The presence in the mucous membrane around the tumor of moderate or small amounts of sulfomucins as well as a complete absence of sulfo- and cyalomucins in the tumor cells are indices of a favourable prognosis. Unfavourable factors indicating the probability of rectal carcinoma recurrence after the operation are as follows: the presence in the tumour cells of a moderate amount of cyalomucins and/or a small amount of sulfomucins as well as a complete absence of sulfomucins in the mucous membrane near tumour. The rule for the individual prognosis has been worked out. Its statistical significance is 80%.

A histological method of double embedding of the tissue in paraplast-piccolyte used for light microscopy is described. The method requires no special equipment, is simple and suitable for all methods of staining of sections obtained upon paraffin embedding, including immunofluorescent and immunoperoxidase procedures.
