[Renal cell carcinoma associated with Xp11 translocation involving the gene].

The paper describes a clinical case of the rare tumor renal cell carcinoma associated with Xp11 translocations involving the TFE3 gene in a 53-year-old male patient. It provides the detailed characteristics of current diagnostic techniques.

[Importance of proliferative potential (as the ratio of a proliferative cells number and duration of mitosis) in diagnoses of malignant degree and prognosis of adrenocortical cancer].

The aim of research has been the estimation of a proliferative potential as simultaneous detection of a proliferative cells number (Ki-67 index) and duration of mitosis (nucleolar argyrophilic protein expression--B23/nucleophosmin and C23/nucleolin) at patients with adrenocortical cancer. In according to lifetime of patients after operation 2 groups had been sorted out. The first one included patients surviving 56.

[Prognistic value of a study of the expression of argyrophilic nucleolar organizer region associated proteins in case of papillary thyroid cancer].

The prognosis in papillary thyroid cancer (PTC) is usually good. Ten-year survival can be seen in 90-98% of patients. Immunohistochemical study (antigen K-67) ascertained that a female patient with PTC had a low number of proliferating cells, which is usually seen in the favorable course of the disease.
