简介
BRCA1-associated protein 1 (BAP1) immunohistochemistry (IHC) was assessed as a predictive biomarker for pemetrexed-based treatment in non-surgically treated malignant pleural mesothelioma (MM) patients.
IHC was performed on 168 MM patient slides to assess BAP1 loss (BAP1-) or retain (BAP1+). BAP1 mouse monoclonal antibody (C-4) was used. Gender, age, performance status (PS), subtype, types of treatment and overall survival (OS) was retrieved from medical records and registries. Clinical endpoint was OS. Data were analyzed by Fisher´s exact test, Kaplan-Meier estimate, log rank test and cox regression.
In total, 91 MM patients that received best supportive care (BSC) and 77 treated with pemetrexed were included in the study (Table 1). Each group was analyzed according to BAP1- or BAP1+. A significantly higher OS was observed in the pemetrexed group for BAP1- versus BAP1+ (OS=20 vs 10 …
