Brief Summary

Sex
Not specified
Target Recruitment
98
Inclusion Criteria

Age between 18-75 years

Primary gastric adenocarcinoma of first diagnosis not previously treated

Laparoscopic finding of positive peritoneal cytology and / or peritoneal localizations of disease (PCI ≤ 6), confirmed by histological examination

Signature of informed consent

ECOG PS scale 0-1

Patients of childbearing potential will be included in the study and monitored by serum pregnancy tests before each chemotherapy cycle and each PIPAC and at the end of treatment. Oral contraceptives will not be used due to the already high thrombotic risk related to the disease, but all other contraceptives will be used according to CTFG indications on contraception.

Active hepatitis B or C

HIV infection

creatinine clearance less than 30ml / min

PCI> 6

Localization of the primary site of disease in the gastric esophagus junction of esophageal relevance (Siewert I-II)

Previous allergic reactions to cisplatin or doxorubicin

Haemorrhagic or occlusive manifestation of disease that candidates the patient for palliative surgery

ASA IV

Primary Outcome Measures
NameTimeMethod
Secondary Resectability Rate (%) evaluated as the % of patients in the 2 arms who will go to CRS and HIPEC compared to the total number of participants at the end of 6 or 12 cycles of chemotherapy in the Arm A and at the end of the 6 cycles of chemotherapy and the 3 PIPACs in arm B; PFS at 1 and 3 years measured as time from randomization at the first evidence of progression (peritoneal or extraperitoneal) or death of patient for any cause, whichever comes first.

Secondary Outcome Measures
NameTimeMethod
overall survival at 1 and 3 years, measured as survival time from randomization until death from any cause; this endpoint will be compared between the two treatment arms

For each patient in Arm B, starting from second cycle of PIPAC, a PRGS score will be assigned for each of the 4 biopsies performed, associated with an average PRGS score, given by the arithmetic mean of the individuals scores. In Arm A, this evaluation can only be carried out on the first occasion restaging after 3 months of treatment on biopsies performed during laparoscopy restaging or at the end of 6 months in those patients with stable disease who continued treatment chemotherapy
