Dejeu V, Dejeu P, Muresan A, Bradea P, Dejeu D. Analysis of Patient Outcomes following Curative R0 Multiorgan Resections for Locally Advanced Gastric Cancer: A Systematic Review and Meta-Analysis. J Clin Med 2024; 13:3010. [PMID: 38792552 PMCID: PMC11121797 DOI: 10.3390/jcm13103010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 04/30/2024] [Accepted: 05/05/2024] [Indexed: 05/26/2024] Open
Abstract
Background: This systematic review examines the efficacy of multiorgan resection (MOR) in treating locally advanced gastric cancer (LAGC), focusing on survival outcomes, postoperative morbidity, and mortality. Methods: We conducted a comprehensive search of studies in PubMed, Scopus, and Embase up to November 2023, based on the PRISMA guidelines. The inclusion criteria focused on clinical trials, observational studies, case-control studies, and qualitative research, involving patients of any age and gender diagnosed with LAGC undergoing MOR aimed at R0 resection, with secondary outcomes focusing on survival rates, postoperative outcomes, and the effects of adjuvant and neoadjuvant therapies. Exclusion criteria ruled out non-human studies, research not specifically focused on LAGC patients undergoing MOR, and studies lacking clear, quantifiable outcomes. The quality assessment was performed using the Newcastle-Ottawa Scale. The final analysis included twenty studies, involving a total of 2489 patients across a time span from 2001 to 2023. Results highlighted a significant variation in median survival times ranging from 10 to 27 months and R0 resection rates from 32.1% to 94.3%. Survival rates one-year post-R0 resection varied between 46.7% and 84.8%, with an adjusted weighted mean of 66.95%. Key predictors of reduced survival included esophageal invasion and peritoneal dissemination, the presence of more than six lymph nodes, and tumor sizes over 10 cm. Nevertheless, the meta-analysis revealed a significant heterogeneity (I2 = 87%), indicating substantial variability across studies, that might be caused by differences in surgical techniques, patient demographics, and treatment settings which influence survival outcomes. Results: The review underlines the important role of achieving R0 resection status in improving survival outcomes, despite the high risks associated with MOR. Variability across studies suggests that local practice patterns and patient demographics significantly influence results. Conclusions: The findings emphasize the need for aggressive surgical strategies to improve survival in LAGC treatment, highlighting the importance of achieving curative resection despite inherent challenges.

Zhang J, Sun J, Liu J, Mei S, Quan J, Hu G, Li B, Zhuang M, Wang X, Tang J. Comparison of short- and long-term outcomes between laparoscopic and open multivisceral resection for clinical T4b colorectal cancer: A multicentre retrospective cohort study in China. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2024; 50:107316. [PMID: 38086316 DOI: 10.1016/j.ejso.2023.107316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 10/31/2023] [Accepted: 12/04/2023] [Indexed: 01/16/2024]
Abstract
BACKGROUND Laparoscopic surgery is controversial for patients with clinical T4b colorectal cancer (CRC) who require multivisceral resection (MVR). This study aims to explore and compare the safety and long-term oncological outcomes of laparoscopic surgery and open surgery for patients with clinical T4b CRC. MATERIALS AND METHODS This study was a retrospective cohort study based on a multicentre database. According to the operation method, the patients were divided into a laparoscopic MVR group and an open MVR group. The short-term and long-term outcomes were compared. RESULTS From January 2010 to December 2021, a total of 289 patients in the laparoscopic MVR group and 349 patients in the open MVR group were included. After propensity score matching, patients were stratified into a laparoscopic MVR group (n = 163) and an open MVR group (n = 163). Compared with the open MVR group, the laparoscopic MVR group had less blood loss (100 vs. 200, p < 0.001), a shorter time to first flatus (3 vs. 4, P < 0.001), a shorter postoperative hospital stay (10 vs. 12, P < 0.001), and a lower incidence of surgical site infection (2.5 % vs. 8.0 %, P = 0.043). The Kaplan-Meier curves showed that the two groups had similar overall survival (P = 0.283) and disease-free survival (P = 0.152). CONCLUSION Compared with open MVR, laparoscopic MVR had less blood loss, fewer surgical site infection complications, faster recovery and a shorter hospital stay. The long-term survival outcome of laparoscopic MVR was not inferior to that of open MVR.
