The consensus on the prevention and correction of rash in patients with HR+ HER2- metastatic breast cancer treated with alpelisib

The consensus on the prevention and correction of rash in patients with HR+ HER2- metastatic breast cancer treated with alpelisib was developed by the experts of the Russian Society of Clinical Oncology and dermatovenerologists. PIK3CA mutation is a poor prognostic factor for HR+ HER2- metastatic breast cancer. Alpelisib demonstrates efficacy in patients with PIK3CA mutation, but treatment might be associated with adverse events that include rash. All-grade rash was reported in 35.6% patients in SOLAR-1 trial (n=284). According to the published real-world data, for Russian population (n=19) all-grade rash was reported for 37% patients. The consensus contains practical recommendation on management of patients with rash of different grade.
