Cost-effectiveness comparison of prophylactic octreotide and pasireotide for prevention of fistula after pancreatic surgery

Abstract

Purpose: Postoperative pancreatic fistula (POPF) is a major determinant of pancreatic surgery outcome, and prevention of POPF is a relevant clinical challenge. The aim of the present study is to compare the cost-effectiveness of octreotide and pasireotide for POPF prophylaxis.

Methods: A systematic literature review and meta-analysis and a retrospective patient cohort provided the data. Cost-effectiveness was calculated by the incremental cost-effectiveness ratio (ICER) and by decision tree modelling of hospital stay duration.

Results: Six randomised trials on octreotide (1255 patients) and one trial on pasireotide (300 patients) were included. The median POPF incidence without prophylaxis was 19.6 %. The relative risks for POPF after octreotide or pasireotide prophylaxis were 0.54 or 0.45. Octreotide prophylaxis (21 × 0.1 mg) costs were 249.69 Euro, compared with 728.84 Euro for pasireotide (14 × 0.9 mg) resulting in an ICER of 266.19 Euro for an additional 1.8 % risk reduction with pasireotide. Decision tree modelling revealed no significant reduction of median hospital stay duration if pasireotide was used instead of octreotide.

Conclusion: Prophylactic octreotide is almost as effective as pasireotide but incurs significantly fewer drug costs per case. However, the data quality is limited, because the effect of octreotide on clinically relevant POPF is unclear. Together with the lack of multicentric data on pasireotide and its effectiveness, a current off-label use of pasireotide does not appear to be justified.
