The structure of chronic pain and its treatment in 41 cases of advanced malignant tumor of genitals are discussed. Pain syndrome was found to have a certain pattern (site, acuteness, depth, irradiation) which may be used as an additional diagnostic parameter. ⋯ Subarachnoidal blockade by alcohol proved to be the most effective (78%) and lasting (22 days). Analgesia by sacral blockade is less effective but safer.

The predictive value of aspiration and trepan biopsy is analysed in 247 cases of prostatic cancer. The diagnostic value of trepan biopsy is 90.1%; it is not determined by the degree of tumor differentiation. The value of aspiration biopsy varies with different degree of differentiation; it is 42.1% for well-differentiated cancer, 81.2%--for moderately- and 97.4%--for poorly-differentiated tumors. Aspiration biopsy is a safe procedure, while trepan biopsy may be followed by severe complications.
