ADVANCES IN THE NEUROSURGICAL AND COMBINED TREATMENT OF PATIENTS WITH ACROMEGALY

Aim. The study was carried out to identify and analyze the factors of a positive outcome of surgical and radiation treatment of acromegaly. Methods. The work was performed on clinical material and summarizes treatment results of 256 patients (90 males and 166 females). 86% of patients underwent surgical treatment, 14% of patients received radiation therapy during 2002–2018. Significance of factors of a positive outcome of treatment was carried out using the RStudio program. Results. The results of the study revealed that: 1. Significant factors (p <0.05) of a positive outcome of surgical treatment of acromegaly are somatostatin analogs (SSA) therapy before surgery, a small tumor size (microadenomas), and the absence of extrasellar tumor spread. 2. The most significant factor in achieving remission of acromegaly after non-radical adenomectomy is postoperative therapy with SSA (p <0.05). 3. Aggressive pituitary tumors invading surrounding structures, high baseline IGF-1 levels, unfavorable histological findings, macroadenomas, growth hormone levels above 10 μg/L before therapy, and extrasellar tumor spread were associated with less favorable outcomes of acromegaly radiation therapy (RT) (p <0.05). The most significant factor in achieving remission of acromegaly is SSA therapy after RT (p <0.05). Conclusion. Surgical treatment is the optimal primary treatment for acromegaly. Drug therapy with SSA is effective and the preferred treatment after non-radical surgery.
