This study introduces the comprehensive treatment of using neoadjuvant laparoscopic HIPEC and bidirectional chemotherapy for gastric cancer with peritoneal carcinomatosis. The study reports the real benefit of this treatment strategy and analyzes the prognostic factors. The study also provides a recommended patient selection criteria for applying this protocol. The comprehensive treatment showed better tumor clearance and improved survival outcomes in patients with gastric cancer-associated peritoneal carcinomatosis.
Simple Summary The comprehensive treatment of using neoadjuvant laparoscopic HIPEC and bidirectional chemotherapy before cytoreductive surgery has been introduced. We reported the real benefit of this strategy and analyze the prognostic factors on outcome. We also provided a recommended patient selection criteria for applying this protocol. Comprehensive treatment comprising neoadjuvant laparoscopic HIPEC (L-HIPEC) and bidirectional intraperitoneal and systemic induction chemotherapy (BISIC) followed by cytoreductive surgery (CRS) for gastric cancer with peritoneal carcinomatosis (PC) has been developed. However, its benefits and patient selection criteria have not been thoroughly investigated. We retrospectively reviewed 113 patients, with 25 having received comprehensive treatment (L-HIPEC, BISIC, and then CRS-HIPEC; the BISIC group) and 88 having received direct CRS-HIPEC (the CRS group). The BISIC group showed greater tumor clearance in terms of post-CRS peritoneal cancer index ((PCI) 6 vs. 14, p = 0.002) compared to CRS group. The median survival was 20.0 months in the BISIC group and 8.6 months in the CRS group (p = 0.031). Multivariable analysis revealed that the factors associated with increased survival were the BISIC protocol, age, and post-CRS tumor clearance. BISIC significantly improved survival in cases of moderate severity (PCI 11-20) and severe cases (PCI 21-39) without increasing the morbidity rate. We recommend the use of this neoadjuvant strategy for patients with gastric cancer-associated PC and an initial PCI of >10 to provide superior survival outcomes.
