Иммуногистохимическая диагностика гормоно-рецепторного статуса рака молочной железы с прогнозом основных направлений противоопухолевой лекарственной терапии

Abstract

The data on the cost of immunohistochemical diagnosing of the hormone-receptor status and the diagnostic coverage of the women operated for breast carcinoma (BC) in the regions of the Republic of Belarus are presented. During 2008-2013 the percentage of hormone-receptor examination coverage of the BC patients was as follows: Brest region 85,1%, Vitebsk region 61,9%, Mogilev region 88,1%, Gomel region 98,6%. The made pharmacoeconomic analysis of the hormone-receptor status of BC has shown that these examinations constitute a significant part of all IHC examinations in the regional pathoanatomical bureaus and are lower in cost than the analysis of HER2/neu. At the same time, the hormone-receptor status analysis helps to define a considerable group of patients with BC, who have a more favourable prognosis, which requires less expensive hormone therapy. According to the Cancer Registry of the Vitebsk region 500 cases of breast cancer were diagnosed in 2014. The hormone-receptor status and HER2/neu analyses were made in the oncomorphology department in 425 cases. Estrogen and progesterone receptors were immunohistochemically revealed in 54,1% of cases, and the reaction was negative in 34,1% of cases. At the same time 82 cases were characterized by triple negative cancer, which constituted 20% of the total number of invasive breast cancer. The obtained data with the percentage of HER2/neu hyperexpression taken into account help to determine the proportion of women requiring hormonal, targeted and cytostatic therapies.

Представлены данные о стоимости иммуногистохимической (ИГХ) диагностики гормоно-рецепторного статуса и охвата им женщин, оперированных по поводу рака молочной железы (РМЖ) в регионах Республики Беларусь. За 2008-2013 гг. процент охвата исследованиями гормоно-рецепторного статуса пациенток с РМЖ составил: по Брестской области 85,1%, по Витебской 61,9%, по Могилевской 88,1%, по Гомельской 98,6%. Проведенный фармакоэкономический анализ гормоно-рецепторного статуса РМЖ показал, что эти исследования составляют значительный объем ИГХ нагрузки областных патологоанатомических бюро, стоят дешевле, чем определение HER2/neu. В то же время они позволяют выявить довольно значительную группу пациентов с РМЖ с более благоприятным прогнозом, для которой требуется менее затратная гормональная терапия. В 2014 г., согласно канцер-регистру, в Витебской области было выявлено 500 случаев РМЖ. В отделении онкоморфологии проведено 425 исследований гормоно-рецепторного статуса и HER2/neu. Рецепторы эстрогена и прогестерона в опухоли иммуногистохимически определялись в 54,1% случаев, отсутствовали в 34,1%. При этом выявлено 82 случая тройного негативного рака, что составило 20% от общего количества инвазивного РМЖ. Полученные данные с учетом процента гиперэкспресии HER2/neu позволяют определить удельный вес женщин, нуждающихся в гормональной, таргетной и цитостатической терапии.
