Abstract
Currently, cabergoline therapy is the main method of treatment with prolactin. The use of the drug in most cases leads to tumor regression, normalization of prolactin levels and restoration of gonadotropic function. The mechanism of its impact on tumor cells in vivo, which is dynamically traced in the same human tumor, is the case of considerable interest. We observed a 30-year-old patient who was operated on twice for a giant prolactinoma before and on treatment by cabergoline. The morphological study after the first surgery (before introducing of cabergoline therapy) revealed a prolactin-positive pituitary tumor with a Ki-67 labeling index of 8% and with strong expression of dopamine type 2 receptors (D2R), CD31 and CD34. After 4 months, during which the patient received cabergoline at a dose starting from 0.5 mg to 1.5 mg per week, a second transsphenoidal surgery was performed with subtotal removal of residual tumor tissue. During the morphological study of the second biopsy sample, the tumor retained a pronounced immunopositivity to prolactin and D2R, with a decrease in the labeling index Ki-67 to 2%, as well as a decrease in the expression of CD31 and CD34. Subsequent cabergoline therapyresulted in persistent normoprolactinemia, restoration of androgen (and reproductive) status, and no tumor recurrence over a 10-year period on cabergoline treatment. Thus, one of the mechanisms of effect of cabergoline that leads to tumor regression is a decrease in the proliferative index and angiogenesis of the tumor.
