Кроме того, исследовали ткань 49 аденом, 50 узловых зобов и 50 образцов нормальной ткани щитовидной железы (окружающие узлы). Экспрессию Met/HGF-R оценивали полуколичественным иммуногистохимическим методом с учетом пропорциональности (пределы 0-5) и интенсивности (пределы 0-5) окрашивания клеток и вычисления общей экспрессии Met/ HGF-R (предел 0-10). Met/HGF-R отсутствовал в нормальной ткани щитовидной железы, отсутствовал или был фокально выражен в фолликулярных и анапластических опухолях и с разной степенью интенсивности определялся в папиллярных аденокарциномах. Был сделан вывод о том, что низкая экспрессия Met/HGF-R является показателем неблагоприятного прогноза при папиллярном раке щитовидной железы.</p></abstract><trans-abstract xml:lang="en"><p>Clinical implication of Met-hepatocytic growth factor receptor (Met/HGF-R) in thyroid adenocarcinoma tissue was studied on 163 operative thyroid samples (129papillary cancers, 21 follicular cancers, and 13 anaplastic cancers). 49 adenomas, 50 nodular goiters and 50 normal thyroids were compared. Expression of Met/HGF-R was estimated using semiquantitative immunohistochemical method including proportion (limits 0-5) and intensity (limits 0-5) of cell staining and calculation of Met/HGF-R total expression (limit 0-10). Met/HGF-R was not found in normal thyroid tissue, was absent or focally expressed in follicular and aplastic tumors, and was present in different amounts in papillary adenocarcinomas. It is suggested that low expression of Met/HGF-R is an indicator of unfavorable prognosis in papillary thyroid cancer.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Mеt-гепатоцитарный рецептор</kwd><kwd>плохой прогноз</kwd><kwd>опухоли щитовидной железы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Met-hepatocytic receptor</kwd><kwd>poor prognosis</kwd><kwd>thyroid tumors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Янов Ю.
