Выполнено морфологическое и иммуногистохимическое исследование с определением экспрессии тропных гормонов гипофиза, индекса пролиферации ki-67, ХгА, СгII и Сн. По результатам МРТ проведена оценка размеров, распространения и инвазивности опухолей.</p></sec><sec><title>Результаты</title><p>Результаты.</p><p>Среди морфологических типов преобладали «немые» гонадотропиномы — 24 (51,1%) случая. Положительная реакция с антителами (АТ) к АКТГ выявлена в 6 (12,7%) случаях, к СТГ — в 5 (10,6%). В 25,5% случаев определены гормон-негативные аденомы. Медиана ki-67 составила 2% (мин.— 0,5%, макс. — 7%). Экспрессия ХгА, СгII и Сн определена в 83, 93,6, 85,1% аденом соответственно. Иммуноэкспрессия ХгА является неблагоприятным прогностическим фактором в отношении инвазивного роста опухолевой ткани, AUC=0,705. Достоверных корреляций между экспрессией АКТГ, СТГ, CгII, Сн, ki-67 и инвазивным ростом не получено.</p></sec><sec><title>Выводы</title><p>Выводы.</p><p>НАГ обладают скрытым секреторным потенциалом. ХгА, СгII и Сн могут использоваться в качестве иммуногистохимических маркеров НАГ.</p></sec></abstract><trans-abstract xml:lang="en"><p>Pituitary adenomas without clinically active hypersecretion are summarized under the term nonfunctioning pituitary adenomas (NFPAs).

Immunopositivity for ACTH was determined in 6 cases (12,7%), for GH in 5 (10,6%) cases, for PRL in 4 (8,5%). The median level of ki-67 was 2% (min. — 0.5%, max. — 7%). The CgA, SgII, Sn immunopositivity was found in 83, 93,6, 85,1% respectively, being more expressed in gonadotropinomas and null cell adenomas. Invasive growth was detected in 28 (44%) cases, among the invasive adenomas 22 tumors were giant. CgA expression is adverse prognostic factor, area under the curve (AUC) with 0,705. We did not find any correlation between ACTH-, STH-, CgII- and Sn- immunopositivity, ki-67 and invasive growth.</p></sec><sec><title>Conclusions</title><p>Conclusions.</p><p>Our work shows that a majority of NFPAs are truly secreting adenomas with significant numbers comprising potentially hazardous cortico- and somatotropinomas.
