In univariate analysis, total number of cycles of chemotherapy, HR 0.75 (95% CI 0.6–0.93), CEA pre PIPAC, HR1 (95% CI 1–1), Albumin pre –PIPAC, HR 0.8 (95% CI 0.66–0.96), ascites at first PIPAC, HR 1 (95% CI 1–1) and patients who showed radiological response after 3rd PIPAC, HR 3.7(95% CI 1–14) were significant predictors for overall survival (Table S1). Here, ALB is linked to Ascites.
