Фактор роста эндотелия сосудов в диагностике метастазов мышечно-инвазивного рака мочевого пузыря

Фактор роста эндотелия сосудов в диагностике метастазов мышечно-инвазивного рака мочевого пузыря

Abstract

Цель исследования – изучение диагностического значения фактора роста эндотелия сосудов (vascular endothelial growth factor, VEGF) при мышечно-инвазивном раке мочевого пузыря (МИРМП). Материалы и методы. Определение уровня VEGF методом иммуноферментного анализа в сыворотке крови и плазме проводили до оперативного вмешательства у больных с инвазией в пределах органа и с экстраорганным ростом, а также через 12–18 мес после операции у пациентов с рецидивами и метастазами или без таковых. Результаты. Было установлено, что содержание VEGF является одним из показателей активности опухолевого ангиогенеза. Так, повышение уровня VEGF коррелировало с глубиной инвазии опухоли, являясь одним из показателей ее агрессивности и злокачественности, а также метастатического потенциала. В то же время снижение концентрации данного биомаркера у больных МИРМП в послеоперационном периоде сопровождалось уменьшением или отсутствием клинических проявлений опухолевого роста. Выводы. Таким образом, определение содержания VEGF в сыворотке крови и плазме может служить основой для разработки новых методов ранней неинвазивной диагностики МИРМП, прогнозирования течения заболевания и оценки эффективности лечения.

Objective. The diagnostic value of vascular endothelial growth factor (VEGF) in muscle-invasive bladder cancer (MIBC) was estimated. Materials and methods. The level of VEGF was determined by ELISA in blood serum, plasma of patients with cancer invasion within the bladder or with extra-bladder invasion before surgical treatment and of patients with recurrences and metastases or without them 12– 18 months after surgical treatment. Results. Concentration of VEGF was shown to be one of criteria of activity in this disease. Thus, increasing of VEGF level correlated with the degree of the tumor invasion being one of criteria of its aggressive character and malignancy as well as its metastatic potential. At the same time, decreasing of concentration of this biomarker in patients with MIBC in the post-operative period was followed by limitation or absence of clinical manifestation of the tumor progression. Conclusions. Thus, detection of VEGF in blood serum, plasma can serve as the basis for development of new methods of early non-invasive diagnostics of MIBC, prognosis of its course and estimation of the efficiency of treatment.
