[Immunohistochemical investigation of steroid hormones (ER, PR) in breast cancer].

Immunohistochemical investigations were performed in 22 cases of breast cancer. The objective of this study was to assess the presence and distribution of ER and PR in the cancer tissue. We found that expression of the ER and PR in the cancer tissue is variable, which depends on cancer histogenesis (lobular, ductal), histological form, differentiation grade, and stage of its development.

[Strategy and results of treatment in trophoblastic disease].

The study involved 457 cases of ordinary (261), invasive (75) vesicular mole and choriocarcinoma (121-stage I-51.2; stage II-19.8 and stage III-27.

[Combined examination of the hypophysis-adrenal cortex system in breast cancer].

A multimodality radioimmunological and clinicobiochemical study showed an increase in the hydrocortisone level and a decrease in the ACTH level in breast cancer patients. Stage I, following radical mastectomy (RM). A simultaneous increase in the hydrocortisone, ACTH and aldosterone level after RM, chemotherapy, hormone therapy was noted in all patients with breast cancer, Stages II and III, with initially lowered hydrocortisone and aldosterone levels and an elevated ACTH level.
