PG - 1058-1068 LID - 10.1245/s10434-023-14470-8 [doi] AB - PURPOSE: We aimed to evaluate the safety and efficacy of hyperthermic intraoperative thoraco-abdominal chemotherapy (HITAC) and cytoreductive surgery (CRS) for peritoneal carcinomatosis (PC) patients who underwent diaphragm resection. METHODS: PC patients who underwent CRS with diaphragm resection were selected from a prospectively established database and were divided into hyperthermic intraperitoneal chemotherapy (HIPEC) and HITAC groups. The clinicopathological characteristics, treatment-related variables, perioperative adverse events (AEs), and survival outcomes were compared between the two groups. RESULTS: Of 1168 CRS + HIPEC/HITACs, 102 patients were enrolled-61 HITAC patients and 41 HIPEC patients. In the HITAC and HIPEC groups, the incidence of grade III-V AEs was 29.5% versus 34.1% (p = 0.621). The pleural progression rates were 13.2 versus 18.9% (p = 0.462) and the median overall survival (OS) was 50.5 versus 52.7 months (p = 0.958). Median time to progression (TTP) in thoracic disease was not reached. There was no significant difference in perioperative AEs, TTP, and OS for total patients and the completeness of cytoreduction (CC) score subgroups (p > 0.05). Age >/= 60 years (hazard ratio [HR] 4.162, p = 0.026) was an independent risk factor influencing pleural progression, and primary malignant peritoneal mesothelioma (MPM; HR 2.749, p = 0.016) and the presence of two or more serious AEs (SAEs; HR 7.294, p = 0.001) were independent risk factors influencing OS. CONCLUSIONS: HITAC can be performed in carefully selected PC patients who underwent diaphragm resection, with no worsening of the safety profile and a possible benefit for pleural progression. In those patients, age >/= 60 years is associated with a shorter TTP of thoracic disease, while primary MPM and two or more perioperative SAEs are associated with worse OS. CI - (c) 2023.
