1. Determine the maximal tolerated dose (MTD) of Nab paclitaxel (Abraxane®) administered IP by PIPAC in concomitance with cisplatin. (Time Frame - From the time of treatment randomization through 30 days following cessation of treatment): MTD is defined as the lowest dose level at which ≥33% of patients' experience dose limiting toxicity in accordance to CTCAE version 5.0 criteria.
Secondary outcome:
1. Adverse events (AE) and serious adverse events (SAE) (Time Frame - D-1/D10 of each cycle): AE and SAE with predefined toxicity criteria will be applied using CTCAE version 5.0 criteria, documented before and after each cycle of PIPAC treatment. Surgical complications will be assessed according to Clavien classification and comprehensive complication index (CCI)
2. The efficacy (Time Frame - D0 of each cycle): It will be assessed by the objective histological regression and objective tumor response rate (OTR) according to the new regression system for peritoneal cancer (PRGS, peritoneal regression grade score system). The objective response rate (ORR), the clinical benefit rate (CBR) as defined by RECIST version 1.1 criteria and the relevance of radiological response assessed by CT enterography (CT-PCI score).
3. The QoL (Time Frame - D-1/D10 of each cycle): QoL will be evaluated based on the EORTC questionnaire QLQ-C30 Version 3.0 and visual analogic scale for pain (VAS scale).
