This study assessed the cost-effectiveness of pressurized intraperitoneal aerosol chemotherapy with low-dose cisplatin and doxorubicin (PIPAC C/D) for the treatment of advanced gastric cancer. The results showed that PIPAC C/D plus chemotherapy is a cost-effective strategy for upfront therapy, and PIPAC C/D as a second-line therapy has the potential to reduce costs and improve clinical outcomes for patients with advanced gastric cancer.
Objective: The aim of this study was to assess the cost-effectiveness of pressurized intraperitoneal aerosol chemotherapy with low-dose cisplatin and doxorubicin (PIPAC C/D) for the treatment of advanced gastric cancer. Methods: A Partitioned Survival Model followed by state transition Markov model was developed to estimate the costs and effectiveness of the use of PIPAC C/D versus palliative chemotherapy in the UK. The intervention was assessed at two different levels of care, including upfront therapy (PIPAC C/D plus Oxaliplatin in combination with Capecitabine (XELOX) chemotherapy versus first-line chemotherapy alone) and second-line therapy (PIPAC C/D alone versus second-line chemotherapy (ramucirumab monotherapy)). Data from multiple sources, including published literature and UK-based databases, were used to inform the economic model. Results: For the upfront therapy analysis, the estimated total costs in the intervention and comparator arms were 32,606 pound (SD: 3877) pound and 17,844 pound (SD: 920) pound, respectively. PIPAC C/D plus XELOX led to an increase of 0.46 in quality-adjusted life-years (QALYs) gained. The incremental cost per QALY gained was 31,868 pound. For the second-line therapy analysis, the use of PIPAC C/D led to an increase of 0.19 in QALYs and a 21,474 pound reduction in costs, meaning the intervention was a dominant strategy. Conclusions: The cost-effectiveness results for the upfront therapy analysis indicate that PIPAC C/D plus chemotherapy is a cost-effective strategy. Additionally, PIPAC C/D alone as a second-line therapy has the potential to reduce costs and improve clinical outcomes for patients with advanced gastric cancer with peritoneal metastasis.
