Cluster-poor patients have a worse prognostic than cluster-rich patients. Cluster-poor and rich patients were compared for morphological and clinical criteria. (A) BerEP4 staining (tumor cells) of representative cluster-poor and rich ascites. (B) Cluster number distribution in the cohort. Median is represented. (C) Overall survival curve and (D) progression-free survival curve adjusted for WHO performance score, Sugarbaker score, age and BMI using Cox proportional hazard regression models. * p < 0.05, ** p < 0.01
