Postoperative intraperitoneal hyperthermic perfusion improve survival for advanced gastric cancer

Abstract

To evaluate the value of intraperitoneal hyperthermic perfusion (IPHP) in the treatment of gastric cancer. Gastric cancer (GC) is a malignancy with poor prognosis, recent years have demonstrated advances in the use of IPHP for the treatment of advanced gastric cancer (AGC), but the outcome is controversial. Between January 2015 and January 2017, 134 patients with GC were treated with IPHP in our surgery department, 130 of them were advanced GC patients, and other 1439 cases were treated without IPHP for comparison. In this retrospective cohort study, demographic, perioperative data, and follow-up data were analyzed by univariant analysis, Kaplan–Meier and Cox regression survival analysis. We found the 1-year survival in IPHP group was significantly longer than it in non-IPHP group (85.5% vs 73.8%, P = .027). and IPHP decreased mortality 1.8 times in 2-year course (OR = 0.556, P = .004). The incidence rate of total complications in IPHP group was similar to that in the Non-IPHP group (6.67% vs 7.46%, respectively; P = .718). We classified all patients into four groups, operation alone, operation + chemotherapy, operation + IPHP, and operation + IPHP + chemotherapy. The 1-year survival in the groups was 70.2%, 77.5%, 83.1%, and 93.5%, respectively ( P = .001), compared with the group of operation alone, the 2-year mortality risk was decreased 1.76 times (OR = 0.569, P = .030) and 2.59 times (OR = 0.385, P = .022) in operation + IPHP group and operation + IPHP + chemotherapy group. Our results suggest that IPHP could contribute to improve survival of patients with gastric cancer. And the modality of operation + IPHP + chemotherapy is the optimal treatment modality for gastric cancer.

Assessment of the efficacy and safety of intraperitoneal chemotherapy in patients with advanced gastric cancer in Chinese population: a meta-analysis

“…Gastric cancer is currently one of the highest mortality rates and serious cancers in all of the world (Xiao et al, 2018;Yu et al, 2019;Zare et al, 2019). The incidence of gastric cancer usually has no obvious symptoms and signs (Zhang et al, 2019). The detection rate of early gastric cancer is deficient, generally with no apparent symptoms.…”
