^a11 patients had several combinations of distant metastases and only 16 patients had isolated HM. Survival data is for all 27; ^bOnly two controlled study comparison, both case-control; ^cAll patients were R1 resections; ^dUnreliable data due to short observation time and many censured patients; Abbreviations: PM, peritoneal metastases; HM, hepatic metastases; PCI, peritoneal cancer index
