Objectives This is the first UK trial of pressurised intraperitoneal aerosolised chemotherapy (PIPAC) for colorectal cancer peritoneal metastases. This trial aimed to assess the impact of PIPAC in combination with standard of care systemic treatment on: progression free survival (PFS); quality of life (QoL); and short-term complications. In addition, this trial set out to demonstrate that PIPAC can be performed safely in operating theatres within a National Health Service (NHS) setting. Methods Single-centre clinical trial with prospective data collection for patients undergoing 8-weekly PIPAC with oxaliplatin at 92 mg/m2 from January 2019 till January 2022. Progression free survival was assessed using peritoneal carcinomatosis index (PCI) by CT scans and laparoscopy. Quality of life was assessed by EORTC QLQ-C30 questionnaire. Adverse events were recorded using CTCAE. Results Five patients underwent a total of ten PIPAC administrations (median 2, range 1–4). Median PFS was 6.0 months. QoL was maintained across repeat PIPAC procedures but a decrease in social functioning and increased fatigue were evident. Three incidences of grade 3 adverse events occurred but PIPAC was well tolerated. Conclusions The presented data demonstrates that PIPAC is feasible and can be safely delivered within the NHS for patients with colorectal cancer peritoneal metastases, but caution must also be exercised given a risk of adverse events. Systemic chemotherapy can be safely administered at a different unit to the PIPAC procedure if both groups have clear lines of communication and timely data sharing.
