Median dose-normalized tumour paclitaxel concentrations in each of the abdominal quadrants, sampled 0.5 h after initiation of the PIPAC procedure. All concentrations were dose-normalized to 140 mg/m2. Colored boxes: median dose-normalized tumour concentrations stratified per sampling location; Black dots: median dose-normalized tumour PTX concentrations across sampling location; PTX = paclitaxel, PIPAC = pressurized intraperitoneal aerosol chemotherapy, LUA = left upper abdomen, RUA = right upper abdomen, LF = left iliac fossa, RF = right iliac fossa.
