^a 3 patients in IP group did not receive IV chemotherapy.

^b 1 patients did not receive any protocol-based therapy. 1 patient only received 3 cycles of IV therapy after cytoreduction and the data of adverse events were missed.

^cP values were calculated by χ²-test (grades 0, 1, and 2 vs. grades 3 and 4).

^d 1 patient died of mesenteric venous thrombosis after completing 4 cycles of IP therapy and 4 cycles of IV therapy. In the intraperitoneal chemotherapy group, other 3 patients encountered grade 2 thromboembolic events (deep venous thrombosis of the lower extremities). And in the intravenous chemotherapy group, 1 patient encountered a grade 2 thromboembolic event (Upper-extremity deep vein thrombosis), which was PICC line-associated thrombosis³¹
