The relative analysis of clinical endocrine features and pathological types of pituitary microadenomas / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVES</b>To study the relationship between the clinical presentation, endocrinal findings and pathological types in patients with pituitary microadenomas, so as to improve the accuracy of clinical diagnosis and choose the best therapy strategy before the operation.</p><p><b>METHODS</b>From January 2007 to June 2009, the clinical data of 94 patients who were surgically removed pituitary microadenomas were obtained, including the clinical presentation, endocrinal findings and pathological diagnosis. The analysis was accomplished with Chi-square test.</p><p><b>RESULTS</b>Hormonal symptoms were found in 86 patients (91.5%), it occurred more frequently in immunopositive patients (85/92, 92.4%) than in immunonegative patients (1/2, 50.0%) (P < 0.05). The coincidence of hormonal symptoms and immunohistochemistry diagnosis was 71.7%; 88.9% patients had the symptoms of amenorrhea, galactorrhea and sexual function diseases in prolactin (PRL) positive group and 28.1% patients had the symptoms of gigantism or acromegaly in growth hormone (GH) positive group. The coincidence of endocrinal findings and immunohistochemistry diagnosis was 69.0%; 87.7% patients had high level of blood PRL in PRL positive group and 21.9% patients had high level of blood GH in GH positive group.</p><p><b>CONCLUSIONS</b>There is an obvious relationship between the clinical presentation, endocrinal findings and pathological diagnosis in patients with pituitary microadenomas, which may contribute to the clinical diagnosis and treatment of pituitary secreting microadenomas.</p>
