23 апреля 2021 г. прошел виртуальный форум, посвященный вопросам диагностики и лечения пациентов с гормонозависимым HER2-отрицательным распространенным раком молочной железы с мутацией гена PIK3CA с использованием таргетного препарата алпелисиб. Эксперты-онкологи из Франции и России обсудили значение мутации PIK3CA, необходимость и методы ее диагностики, а также обменялись информацией и опытом применения препарата алпелисиб в том числе у пациенток, ранее получавших ингибитор CDK4/6 и резистентных к эндокринной терапии. На клиническом примере эксперты также обсудили вопросы профилактики и коррекции нежелательных явлений.
А virtual forum dedicated to the diagnosis and treatment of patients with hormone-dependent HER2-negative advanced breast cancer (HR+ HER2- aBC) with the PIK3CA mutation using target drug alpelisib was held on April 23, 2021. Oncologists from France and Russia discussed the significance of the PIK3CA mutation, the necessity and methods of its identification. They also shared information and exchanged experience of using alpelisib to treat patients who had previously received a CDK4/6 inhibitor and were resistant to endocrine therapy. Using the example of a clinical case, the experts also discussed the issues of prevention and correction of adverse events.
