Patel M, Arora A, Mukherjee D, Mukherjee S. Effect of hyperthermic intraperitoneal chemotherapy on survival and recurrence rates in advanced gastric cancer: a systematic review and meta-analysis. Int J Surg 2023; 109:2435-2450. [PMID: 37158149 PMCID: PMC10442139 DOI: 10.1097/js9.0000000000000457] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 05/01/2023] [Indexed: 05/10/2023]
Abstract
BACKGROUND Around 5-20% of patients who undergo surgery for advanced gastric cancer (AGC), which invades into the muscularis propria or beyond, have peritoneal carcinomatosis. The peritoneal recurrence rate is 10-54%, which is associated with a poor prognosis. The role of hyperthermic intraperitoneal chemotherapy (HIPEC) in AGC with and without peritoneal carcinomatosis is not clearly defined. METHODS The authors conducted a meta-analysis, in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of the clinical trials and high-quality nonrandomized studies evaluating the role of HIPEC in AGC over the last 10 years. The studies were searched in PubMed, EMBASE, MEDLINE, and Cochrane databases between January 2011 to December 2021. Clinical data including overall survival, recurrence free survival, overall recurrence rate, peritoneal recurrence rate, and complications analyzed using RevMan 5.4. RESULTS Six randomized controlled trials and 10 nonrandomized studies, comprising a total of 1700 patients were included. HIPEC was associated with significantly improved OS at 3 [odd ratio (OR) 1.89, 95% CI: 1.17-3.05] and 5 years (OR 1.87, 95% CI: 1.29-2.71). HIPEC was associated with reduced overall recurrence (OR 0.49, 95% CI: 0.31-0.80) and peritoneal recurrence (OR 0.22, 95% CI: 0.11-0.47). HIPEC was not associated with increased complications. The occurrence of postoperative renal dysfunction was significantly higher in the HIPEC group (OR 3.94, 95% CI: 1.85-8.38). CONCLUSION The role of HIPEC in AGC has evolved over the past decade. HIPEC may improve survival rates and reduce recurrence rates in patients with AGC, without significant increase in complications and with a favorable impact on 3 and 5-year survival.

Abstract
Peritoneal surface malignancies (PSMs) are usually associated with a poor prognosis. Nonetheless, in line with advances in the management of most abdominopelvic metastatic diseases, considerable progress has been made over the past decade. An improved understanding of disease biology has led to the more accurate prediction of neoplasia aggressiveness and the treatment response and has been reflected in the proposal of new classification systems. Achieving complete cytoreductive surgery remains the cornerstone of curative-intent treatment of PSMs. Alongside centralization in expert centres, enabling the delivery of multimodal and multidisciplinary strategies, preoperative management is a crucial step in order to select patients who are most likely to benefit from surgery. Depending on the specific PSM, the role of intraperitoneal chemotherapy and of perioperative systemic chemotherapy, in particular, in the neoadjuvant setting, is established in certain scenarios but questioned in several others, although more prospective data are required. In this Review, we describe advances in all aspects of the management of PSMs including disease biology, assessment and improvement of disease resectability, perioperative management, systemic therapy and pre-emptive management, and we speculate on future research directions.

Abstract
The role of prophylactic hyperthermic intraperitoneal chemotherapy (p-HIPEC) in serosa invasive gastric cancers without gross or microscopic peritoneal disease, to reduce the rate of peritoneal relapse is an area of ongoing research. Although p-HIPEC is effective in reducing the rate of peritoneal relapse and improving disease free and overall survival with or without adjuvant chemotherapy, when added to curative surgery in locally advanced, non-metastatic gastric cancers, the available literature is at best, heterogeneous, centre-specific and skewed. Apart from that, variations in the systemic therapy used, and the presence of the associated nodal disease further complicate this picture. To evaluate the role of p-HIPEC the PubMed, Cochrane central register of clinical trials, and the American Society of Clinical Oncology (ASCO) meeting library were searched with the search terms, “gastric”, “cancer”, “hyperthermic”, “intraperitoneal”, “chemotherapy”, prophylactic”, “HIPEC” in various combinations, and a critical review of the available evidence was done. Although p-HIPEC is a promising therapy in the management of locally advanced gastric cancers, the current evidence is insufficient to recommend its inclusion into routine clinical practice. Future research should be directed towards identification of the appropriate patient subset and towards redefining its role with current peri-operative systemic therapies.

Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Combined with Surgery: A 12-Year Meta-Analysis of this Promising Treatment Strategy for Advanced Gastric Cancer at Different Stages. Ann Surg Oncol 2022; 29:3170-3186. [PMID: 35175455 DOI: 10.1245/s10434-021-11316-z] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Accepted: 12/28/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND This meta-analysis was designed to systematically assess the effectiveness and safety of hyperthermic intraperitoneal chemotherapy (HIPEC) combined with surgery for different stages of advanced gastric cancer (AGC) during the last 12 years. METHODS The Cochrane Library, PubMed, Embase, Web of Science, and China National Knowledge Infrastructure (CNKI) were searched online, and papers were retrieved from other sources. Next, randomized controlled trials (RCTs) and high-quality nonrandomized controlled trials (NRCTs) were selected for this analysis. The meta-analysis was conducted with RevMan5.4 software. RESULT The 10 RCTs and 13 NRCTs selected for the study included 1892 patients. The overall survival rates were higher in the HIPEC group at 1 year (risk ratio [RR], 0.52; P = 0.004) and 3 years (RR, 0.63; P < 0.00001) than in the control group for the patients without peritoneal cancer, and the HIPEC group had a significant reduction in the recurrence rate (RR, 0.60; p < 0.00001). Among the patients with peritoneal carcinomatosis (PC), the HIPEC group had significantly higher overall survival rates at 1 year (RR, 0.62; P = 0.00001), 2 years (RR, 0.85; P = 0.002), and 3 years (RR, 0.87; P = 0.0001), with an increase in the overall median survival time of 4.67 months. The two groups showed no statistically significant difference in terms of complications for patients with PC (RR, 1.03; P = 0.93) or without PC (RR, 1.15; P = 0.51). CONCLUSION For local AGC without PC, standard surgery combined with prophylactic HIPEC could prolong survival and reduce the recurrence rate without more complications. The prognosis of this treatment strategy for patients with PC is closely related to patient selection. Complete cytoreduction combined with therapeutic HIPEC could prolong survival.

Prophylactic hyperthermic intraperitoneal chemotherapy may benefit the long-term survival of patients after radical gastric cancer surgery. Sci Rep 2022; 12:2583. [PMID: 35173230 PMCID: PMC8850581 DOI: 10.1038/s41598-022-06417-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2021] [Accepted: 01/27/2022] [Indexed: 12/24/2022] Open
Abstract
Hyperthermic intraperitoneal chemotherapy (HIPEC) has been proven to improve the survival rate of gastric cancer and reduce peritoneal recurrence. We aimed to evaluate the effectiveness and safety of prophylactic HIPEC after radical gastric cancer surgery in this study. Researchers searched for studies published in PubMed, Embase, Web of science, Scopus, Cochrane, Clinical key databases and Microsoft Academic databases to identify studies that examine the impact of prophylactic HIPEC on the survival, recurrence and adverse events of patients undergoing radical gastric cancer surgery. RevMan 5.3 was used to analyze the results and risk of bias. The PROSERO registration number is CRD42021262016. This meta-analysis included 22 studies with a total of 2097 patients, 12 of which are RCTs. The results showed that the 1-, 3- and 5-year overall survival rate was significantly favorable to HIPEC (OR 5.10, 2.07, 1.96 respectively). Compared with the control group, the overall recurrence rate and peritoneal recurrence rate of the HIPEC group were significantly lower (OR 0.41, 0.24 respectively). Significantly favorable to the control group in terms of renal dysfunction and pulmonary dysfunction complications (OR 2.44, 6.03 respectively). Regarding the causes of death due to postoperative recurrence: liver recurrence, lymph node and local recurrence and peritoneal recurrence, the overall effect is not significantly different (OR 0.81, 1.19, 0.37 respectively). 1-, 3- and 5-year overall survival follow-up may be incremented by the prophylactic HIPEC, and which reduce the overall recurrence rate and peritoneal recurrence rate. HIPEC may have high-risk of pulmonary dysfunction and renal dysfunction complications. No difference has been found in the deaths due to recurrence after surgery.

Abstract
Gastric cancer (GC) patients with peritoneal metastasis tend to achieve poor clinical outcomes. Until recently, the treatment options were limited mainly to either palliative chemotherapy or radiation therapy in exceptional cases. Currently, these patients benefit from multimodal treatment, such as cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC). Despite good overall results, this treatment modality is still widely debated. The following study is designed to assess the papers about the possible application and utility of HIPEC in GC. A search in the PubMed, Web of Science, and Scopus databases was performed to assess the papers devoted to the role of HIPEC in GC treatment; a literature search was performed until March 21st; and, finally, 50 studies with a total number of 3946 patients were analyzed. According to the most recent data, it seems to be reasonable to limit the duration of HIPEC to the shortest effective time. Moreover, the drugs used in HIPEC need to have equal concentrations and the same solvent. Perioperative chemotherapy needs to be reported in detail and, furthermore, the term "morbidity" should be defined more clearly by the authors.

Abstract
Background Reducing peritoneal recurrence after radical surgery is an important choice to improve the prognosis of patients with advanced gastric cancer. Intraoperative intraperitoneal chemotherapy has the potential to be a promising treatment strategy. In the present study, we conducted a multi-center, randomized, controlled clinical study to evaluate the efficacy and safety of intraoperative intraperitoneal chemotherapy using sustained-release fluorouracil implants plus radical gastrectomy and adjuvant chemotherapy for cTNM stage III gastric cancer. Methods The patients were randomized into intraperitoneal chemotherapy group (sustained-release fluorouracil implants administration after standard D2 radical gastrectomy, and followed by XELOX adjuvant chemotherapy) and control group (standard D2 radical gastrectomy, and followed by XELOX adjuvant chemotherapy). A total of 122 patients from three centers were enrolled from September 2015 to February 2017. Results One hundred and two eligible patients completed the treatment course. The median follow-up time was 41.7 months (36.1–52.9 months). The 3-year progression-free survival rate and overall survival of patients in the intraperitoneal chemotherapy group were 43.9% and 49.1%, respectively, which were significantly better than those of the control group, 31.0% and 38.4%. In the intraperitoneal chemotherapy group, the number of cases with peritoneal recurrence was significantly less than that of the control group, 9 cases (17.3%) vs. 19 cases (44.2%). There were neither significant differences between the groups in the incidence of hematogenous metastasis, lymph node metastasis, nor local metastasis. Conclusion For cTNM stage III gastric cancer, intraoperative sustained-release fluorouracil implants after radical resection combined with postoperative adjuvant chemotherapy, could significantly reduce the risk of peritoneal recurrence and prolong PFS.
