[PMID: 38942631 DOI: 10.1016/j.asjsur.2024.06.051] [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: 08/08/2023] [Revised: 12/19/2023] [Accepted: 06/19/2024] [Indexed: 06/30/2024] Open
Abstract
Distal gastrectomy (DG) with lymph node dissection for gastric cancer is routinely performed. In this meta-analysis, we present an updated overview of the perioperative and oncological outcomes of laparoscopic DG (LDG) and robotic DG (RDG) to compare their safety and overall outcomes in patients undergoing DG. An extensive search was conducted using the MEDLINE, EMBASE, PubMed, Web of Science, and the Cochrane Central Register of Controlled Trials from the establishment of the database to June 2023 for randomized clinical trials comparing RDG and LDG. The primary outcome was operative results, postoperative recovery, complications, adequacy of resection, and long-term survival. We identified twenty studies, evaluating 5,447 patients (1,968 and 3,479 patients treated with RDG and LDG, respectively). We observed no significant differences between the two groups in terms of the proximal resection margin, number of dissected lymph nodes, major complications, anastomosis site leakage, time to first flatus, and length of hospital stay. The RDG group had a longer operative time (P < 0.00001), lesser bleeding (P = 0.0001), longer distal resection margin (P = 0.02), earlier time to oral intake (P = 0.02), fewer overall complications (P = 0.004), and higher costs (P < 0.0001) than the LDG group. RDG is a promising approach for improving LDG owing to acceptable complications and the possibility of radical resection. Longer operative times and higher costs should not prevent researchers from exploring new applications of robotic surgery.

A meta-analysis evaluating wound infections and other complications following distal versus complete gastrectomy for gastric cancer. Int Wound J 2024; 21:e14516. [PMID: 38084020 PMCID: PMC10958092 DOI: 10.1111/iwj.14516] [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: 11/07/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 03/23/2024] Open
Abstract
A meta-analysis investigation was carried out to measure the wound infections (WIs) and other postoperative problems (PPs) of distal gastrectomy (DG) compared with total gastrectomy (TG) for gastric cancer (GC). A comprehensive literature investigation till February 2023 was used and 1247 interrelated investigations were reviewed. The 12 chosen investigations enclosed 2896 individuals with GC in the chosen investigations' starting point, 1375 of them were TG, and 1521 were DG. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the WIs and other PPs of DG compared with TG for GC by the dichotomous approaches and a fixed or random model. TG had significantly higher overall PP (OR, 1.58; 95% CI, 1.15-2.18, p = 0.005), WIs (OR, 1.69; 95% CI, 1.07-2.67, p = 0.02), peritoneal abscess (PA) (OR, 2.99; 95% CI, 1.67-5.36, p < 0.001), anastomotic leakage (AL) (OR, 1.90; 95% CI, 1.21-2.97, p = 0.005) and death (OR, 2.26; 95% CI, 1.17-4.37, p = 0.02) compared to those with DG in individuals with GC. TG had significantly higher overall PP, WIs, PA, AL and death compared to those with DG in individuals with GC. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

Abstract
OPINION STATEMENT The surgical treatment of gastric carcinoma has progressed significantly in the past few decades. A major milestone was the establishment of multimodal therapies for locally advanced tumours. Improvements in the technique of endoscopic resection have supplanted surgery in the early stages of many cases of gastric cancer. In cases in which an endoscopic resection is not possible, surgical limited resection procedures for the early stages of carcinoma are an equal alternative to gastrectomy in the field of oncology. Proximal gastrectomy is extensively discussed in this context. Whether proximal gastrectomy leads to a better quality of life and better nutritional well-being than total gastrectomy depends on the reconstruction chosen. The outcome cannot be conclusively assessed at present. For locally advanced stages, total or subtotal gastrectomy with D2 lymphadenectomy is now the global standard. A subtotal gastrectomy requires sufficiently long tumour-free proximal resection margins. Recent data indicate that proximal margins of at least 3 cm for tumours with an expansive growth pattern and at least 5 cm for those with an infiltrative growth pattern are sufficient. The most frequently performed reconstruction worldwide following gastrectomy is the Roux-en-Y reconstruction. However, there is evidence that pouch reconstruction is superior in terms of quality of life and nutritional well-being. Oncological gastric surgery is increasingly being performed laparoscopically. The safety and oncological equivalency were first demonstrated for early carcinomas and then for locally advanced tumours, by cohort studies and RCTs. Some studies suggest that laparoscopic procedures may be advantageous in early postoperative recovery. Robotic gastrectomy is also increasing in use. Preliminary results suggest that robotic gastrectomy may have added value in lymphadenectomy and in the early postoperative course. However, further studies are needed to substantiate these results. There is an ongoing debate about the best treatment option for gastric cancer with oligometastatic disease. Preliminary results indicate that certain patient groups could benefit from resection of the primary tumour and metastases following chemotherapy. However, the exact conditions in which patients may benefit have yet to be confirmed by ongoing trials.

Risks and benefits of additional surgery for early gastric cancer in the upper third of the stomach meeting non-curative resection criteria after endoscopic submucosal dissection. World J Surg Oncol 2022; 20:311. [PMID: 36155115 PMCID: PMC9511772 DOI: 10.1186/s12957-022-02780-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2022] [Accepted: 09/07/2022] [Indexed: 12/05/2022] Open
Abstract
Background Additional surgery is recommended after non-curative endoscopic submucosal dissection for early gastric cancer. However, it is not easy to recommend for tumors located in the upper third of the stomach, because it would be a total or proximal gastrectomy. This study aimed to evaluate the actual risks and benefits of additional gastrectomy for upper third tumors. Methods We reviewed the clinicopathological data of patients who underwent total or proximal gastrectomy for early gastric cancer in the upper third of the stomach between March 2002 and January 2021. The incidence of lymph node metastasis and postoperative complications were calculated, and risk factors for lymph node metastasis were identified using logistic regression analysis. Survival rates were analyzed using the Kaplan–Meier method and log-rank test. Results A total of 523 patients underwent total or proximal gastrectomy for early gastric cancer; 379 of them had tumors meeting the non-curative resection criteria for endoscopic submucosal dissection. The overall lymph node metastasis rate was 9.5%, and lymphovascular invasion was the only significant risk factor for lymph node metastasis (p < 0.001). The most common sites of lymph node metastasis were stations 1, 3, and 7, with their rates being 3.2%, 3.7%, and 3.2%, respectively. Overall and severe (Clavien–Dindo grade III or higher) postoperative complication rates were 21.1% and 14.0%, respectively, while postoperative mortality was 0.5% (2/379). The 5-year overall survival rates for patients with and without lymph node metastasis were 96.1% and 81.1%, respectively (p = 0.076). Conclusions Before planning an additional gastrectomy after non-curative endoscopic resection for the upper third tumor, we should consider both the benefit of the 9.5% curability for lymph node metastasis and the risks of the 21% postoperative complications and 0.5% mortality.

Abstract
Distal gastrectomy (DG) and total gastrectomy (TG) are the most common types of radical surgery for patients with middle-third gastric cancer (MTGC). However, the indications and benefits of the two procedures still remain controversial. The present meta-analysis aimed to compare the surgical and oncological outcomes of DG and TG in the treatment of MTGC. A rigorous literature review was performed in the databases of PubMed, Embase, Web of Science, China National Knowledge Infrastructure and Chinese BioMedical Literature to retrieve studies published up to February 2022. The Newcastle-Ottawa Scale was used to assess the quality of included studies and a meta-analysis was performed using RevMan 5.3 software. A total of 12 retrospective studies performing comparisons of DG and TG were included in the present meta-analysis. For patients who underwent DG, a lower rate of overall post-operative complications, anastomosis leakage and intro-abdominal infection was determined. No significant difference was observed between DG and TG in the 5-year overall survival when the proximal resection margin ranged from 3 to 5 cm. Although DG was associated with a higher 5-year overall survival rate when compared to TG, there was no significant difference in the stratified analyses by TNM stage. In conclusion, the prognosis of MTGC did not depend on the extent of gastrectomy. With lower complications and acceptable oncological outcomes, DG was a safe and feasible surgical procedure for MTGC when a negative proximal margin was confirmed.

Abstract
BACKGROUND Application of indocyanine green (ICG) fluorescence imaging is effective in guiding laparoscopic radical lymphadenectomy for gastric cancer. However, the optimal approach for indocyanine green injection is controversial. Therefore, the objective of this study was aimed to compare the efficacy and ICG injection between the preoperative submucosal and intraoperative subserosal approaches for lymph node (LN) tracing during laparoscopic gastrectomy. METHOD This randomized controlled trial (ClinicalTrials.gov, NCT04219332) included 266 patients with potentially resectable gastric cancer (cT1-T4a, N0/+, M0) enrolled from a tertiary teaching center between December 2019 and October 2020. The primary endpoint was total number of retrieved LNs. RESULTS In total, 259 patients (n = 130 and n = 129 in the submucosal and subserosal groups, respectively) were included in the per-protocol analysis. There are no significant differences in total number of retrieved LNs between the two groups (49.8 vs. 49.2, P = 0.713). The rate of LN noncompliance in the submucosal group was comparable to that in the subserosal group (32.3% vs. 33.3%, P = 0.860). No significant difference was found between the submucosal and subserosal groups in terms of the incidence (17.7% vs. 16.3%; P = 0.762) or severity of postoperative complications. The mean fluorescence cost in the submucosal group was higher than that in the subserosal group ($335.3 vs. $182.4; P < 0.001). The overall treatment satisfaction score was lower in the submucosal group than in the subserosal group (70.5 vs. 76.1%, P = 0.048). CONCLUSION ICG administered by subserosal injection was comparable to that administered by submucosal injection for lymph node tracing in gastric cancer. However, the former approach imposed a lower economic and mental burden on patients undergoing laparoscopic D2 lymphadenectomy. TRIAL REGISTRATION ClinicalTrials.gov, NCT04219332 .

J Gastrointest Surg 2021; 25:2484-2494. [PMID: 33821415 DOI: 10.1007/s11605-021-04975-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Accepted: 03/03/2021] [Indexed: 01/31/2023]
Abstract
BACKGROUND It remains unclear whether laparoscopic conversation to open gastrectomy causes higher morbidity and has an adverse effect on the long-term survival outcomes of patients with gastric cancer. This study was designed to evaluate the impact of the conversion on short and long-term outcomes of patients with locally advanced gastric cancer (AGC). METHODS We retrospectively investigated 871 patients who initially underwent laparoscopic gastrectomy (LG) for pathologically confirmed diagnosis of AGC between February 2009 and April 2018. The patients were grouped as the conversion (CONV) group and completed laparoscopic (LAP) group. The 1:2 propensity score matching was performed to reduce the effect of bias due to the imbalanced baseline features between the two groups. Multivariate analyses were performed to identify risk factors for conversion and poor survival. RESULTS After propensity-score matching, 168 patients (56 in the CONV group and 112 in the LAP group) were studied. The CONV group was associated with significantly longer operation time (252.4 vs. 216.7 min, P < 0.001) and greater estimated blood loss (234.8 vs. 171.2 ml, P < 0.001) as compared with the LAP group. The time to first flatus (3.8 vs. 3.3 days, P = 0.043), time to start a liquid diet (4.1 vs. 3.5 days, P = 0.021), and postoperative hospital stay (8.7 vs. 7.6 days, P = 0.020) were significantly longer in the CONV group than that in the LAP group. The overall complication rate did not differ significantly between the CONV group and the LAP group (16.1% vs. 12.5%, P = 0.692). Both 5-year overall survival (OS) and 5-year disease-free survival (DFS) did not differ significantly between the CONV group and the LAP group (P = 0.805, P = 0.945, respectively). Multivariate analysis showed that lymphovascular invasion and stage III were independent prognostic factors for poor OS and DFS, whereas conversion was not. CONCLUSIONS The conversion from laparoscopic to open gastrectomy had no negative impact on morbidity and long-term survival outcomes for patients with locally AGC.

Abstract
Background: Because of the challenge of jejunal closure recanalization, uncut Roux-en-Y reconstruction remains controversial. This study aimed to investigate the incidence of recanalization after uncut Roux-en-Y reconstruction in pigs and a small number of patients. Methods: Twenty miniature pigs were subjected to distal gastrectomy and uncut Roux-en-Y reconstruction using various rows of linear staplers to block the intestine. The pigs were sacrificed, and the incidence of recanalization was investigated 1 month after the operation. From December 2018 to June 2019, 10 patients with gastric cancer who had undergone elective laparoscopy-assisted distal gastrectomy and uncut Roux-en-Y reconstruction were included in this study. The primary study outcome was recanalization of the afferent limb, demonstrated by gastrointestinal radiography 1, 3, and 6 months after surgery. Various numbers of staple lines across the afferent jejunal limb were applied for closure: 2 staple lines in 2 pigs, 4 staple lines in 6 pigs, 6 staple lines in 8 pigs, and 8 staple lines in 4 pigs. Results: Complete recanalization was detected in all 20 pigs 1 month postoperatively. Recanalization was detected in five cases (50%) by gastrointestinal radiography. Among them, 1 case of recanalization was found in the 1st month after the operation, 2 cases were found in the 3rd month, and another 2 cases were found in the 6th month. Bile reflux was detected by endoscopy in 2 patients with recanalization. Conclusions: The occurrence of afferent limb recanalization after uncut Roux-en-Y reconstruction is high, and using additional staplers alone cannot decrease the incidence of recanalization. Based on our study, uncut Roux-en-Y reconstruction is not recommended.

Risk Factors and Clavien-Dindo Classification of Postoperative Complications After Laparoscopic and Open Gastrectomies for Gastric Cancer: A Single-Center, Large Sample, Retrospective Cohort Study. Cancer Manag Res 2020; 12:12029-12039. [PMID: 33262653 PMCID: PMC7700075 DOI: 10.2147/cmar.s275621] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Accepted: 10/28/2020] [Indexed: 12/23/2022] Open
Abstract
Background Laparoscopy has been increasingly used for the surgery of gastric cancer. However, the postoperative complications are still under-investigated and the short-term results of laparoscopic gastrectomy remain controversial. This study aimed to explore the differences of postoperative complications between laparoscopic and open radical gastrectomies in patients with gastric cancer through the large sample size, retrospective cohort study, and evaluate the safety of laparoscopy in patients who underwent radical gastrectomy. Patients and Methods A total of 2,966 patients with gastric cancer (TNM I~III) who underwent laparoscopy or open gastrectomy from February 2009 to March 2016 were enrolled in this study. Complications were categorized according to the Clavien–Dindo classification. The incidence and severity of complications between laparoscopic and open gastrectomy were compared using one-to-three propensity score matching (PSM) analysis. Logistic regression analyses were performed to identify risk factors related to postoperative complications. Results A total of 2,966 patients were included in the study, including 687 (23.2%) in the LG (Laparoscopy gastrectomies) group and 2,279 (76.8%) in the OG (open gastrectomies) group. After PSM, a well-balanced cohort of 2,373 patients (676 cases in the LG group and 1,697 cases in the OG group) was further analyzed. The results showed that the incidence of overall complications in the LG group was significantly less than the OG group (15.4% vs 20.8%, P=0.003). However, the severe complications of the LG group showed no difference towards the OG group (5.8% vs 5.8%, P=0.952). Multivariate analysis revealed that laparoscopic surgery is a protective factor for the reduction of postoperative complications. Age ≥60 years, ASA classification IIIc and estimated blood loss ≥200 mL were confirmed as independent risk factors of overall complications. Conclusion Compared with traditional open gastrectomy, LG is safe and feasible with less trauma and fewer complications for patients with gastric cancer.

Abstract
Background The benefits of laparoscopic gastrectomy (LG) in elderly gastric-cancer patients still remain unclear. The purpose of this study was to evaluate the feasibility and safety of LG in elderly gastric-cancer patients. Methods We retrospectively evaluated patients who underwent LG or open gastrectomy (OG) between June 2009 and July 2015 in a single high-volume center. We compared surgical, short-term, and long-term survival outcomes among an elderly (≥70 years old) LG (ELG) group (n = 114), a non-elderly (<70 years old) LG (NLG) group (n = 740), and an elderly OG (EOG) group (n = 383). Results Except for extended time to first flatus, the surgical and short-term outcomes of the ELG group were similar to those of the NLG group. The ELG group revealed comparable disease-specific survival (DSS) rates to the NLG group (64.9% vs 66.2%, P = 0.476), although the overall survival (OS) rate was lower (57.0% vs 65.5%, P < 0.001) in the ELG group than in the NLG group. The ELG group showed longer operation time than the EOG group (236.4 ± 77.3 vs 179 ± 52.2 min, P < 0.001). The ELG group had less estimated blood loss (174.0 ± 88.4 vs 209.3 ± 133.8, P = 0.008) and shorter post-operative hospital stay (8.3 ± 2.5 vs 9.2 ± 4.5, P = 0.048) than the EOG group. The severity of complications was similar between the ELG and NLG groups. Multivariate analysis confirmed that LG was not a risk factor for post-operative complications. Conclusions LG is a feasible and safe procedure for elderly patients with acceptable short- and long-term survival outcomes.

Surg Endosc 2020; 35:3572-3583. [PMID: 32780230 DOI: 10.1007/s00464-020-07820-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 07/10/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Robotic distal gastrectomy (RDG) has been increasingly used for the treatment of gastric cancer in recent year. However, whether RDG could reduce the morbidity when compared to laparoscopic distal gastrectomy (LDG) remains controversial. This study aimed to compare the morbidity and short-term surgical outcomes of RDG and LDG for gastric cancer and identify the related risk factors. METHODS Between March 2010 and August 2019, consecutive patients undergoing RDG or LDG (519 and 957 patients, respectively) at our institution were included in this study. Postoperative complications were stratified according to the Clavien-Dindo (C-D) classification. We performed one-to-one propensity score matching (PSM) analysis, and evaluated postoperative morbidity and short-term surgical outcomes in PSM 1032 patients undergoing RDG or LDG. RESULTS After PSM, the two groups were well-balanced. The mean blood loss of the RDG group was about 27 mL less than that of the LDG group (112.1 vs 139.0 mL, P < 0.001). The RDG group had more retrieved lymph nodes than that in the LDG group (32.7 v 30.2, P < 0.001). The RDG group showed a similar overall (9.9% vs 10.7%, P = 0.682), severe (2.7% vs 3.7%, P = 0.376), local (5.6% vs 5.2%, P = 0.783), and systemic complication rates (5.4% vs 6.0%, P = 0.688). There were no significant differences in mortality between the two groups (RDG 0% vs LDG 0.2%, P = 1.000). Subgroup analyses showed no significant differences in most stratified parameters. Age > 65 years and ASA III were identified as two major risk factors for complications. CONCLUSION RDG could be a safe and feasible in treating gastric cancer compared to LDG. However, we did not observe significant reduction in postoperative complications of RDG compared with LDG, although the use of robotic system is assumed to provide a technically superior operative environment.

Abstract
Objective: Cancer-associated systemic inflammation response and hyperfibrinogenemia play crucial roles in cancer progression and prognosis. In this study, we assessed the clinical value of the preoperative fibrinogen and the neutrophil-lymphocyte ratio (NLR) in patients with adenocarcinoma of the esophagogastric junction (AEG) and upper gastric cancer (UGC). Methods: Patients with AEG or UGC who underwent curative surgery were divided into a training set (n=161) and a validation set (n=195). Univariate and multivariate Cox analyses were performed to evaluate the prognostic indicators for overall survival (OS). The optimization cut-off values for fibrinogen and the NLR were 3.09g/L and 1.84, respectively. The combination of fibrinogen and NLR (F-NLR) was 2 for patients with high fibrinogen (≥3.09g/L) and elevated NLR (≥1.84), whereas those with one or neither were indexed as 1 or 0, respectively. Results: F-NLR was identified as an independent prognostic indicator for OS in the training set (P=0.007) which was confirmed in the validation set (P=0.003). In the subgroup analyses, the prognostic significance of F-NLR was still maintained for stages I-II (P = 0.030 in the training set; and P =0.020 in the validation set) and III (P = 0.001 in the training set; and P <0.001 in the validation set).Notably, among patients with F-NLR 2 could benefit from adjuvant chemotherapy compared with those with F-NLR 0-1 (P = 0.020 in the training set; and P =0.005 in the validation set). Conclusions: The preoperative F-NLR score is an independent prognosis indicator for patients with AEG and UGC. And it may help clinicians to identify those patients who at high prognostic risk and will benefit from planning individualized treatment strategies.

Abstract
BACKGROUND It is still remains unclear whether high-risk patients with gastric cancer can benefit from the application of laparoscopic gastrectomy (LG). The aim of this systematic review was to evaluate the surgical and long-term outcomes after LG and open gastrectomy (OG) for high-risk patients with gastric cancer. METHODS We performed a systematic literature search in various databases from January 1994 to June 2018. Patients who had≥1 of the following conditions were defined as high-risk patients: (1) age≥70 years; (2) BMI≥30 kg/m2; (3) ASA (American Society of Anesthesiologists) grade≥3; or (4) clinical T4 stage (cT4). The results were analyzed according to predefined criteria. RESULTS In the present meta-analysis, the outcomes of 12 non-randomized controlled studies enrolling 1651 patients (873 in the LG group and 778 in the OG group) were pooled. The estimated blood loss was significantly lower in the LG group than those in the OG group (P < 0.01). There was no significant difference between two groups in operative time (P = 0.17) and number of harvested lymph nodes (P = 0.21). In the LG group, the time to flatus (P < 0.01), time to food intake (P < 0.01), and postoperative hospital stay (P < 0.01) were significantly shorter than those in the OG group. A lower overall postoperative complication rate was observed in the LG group (P < 0.01). The incidence of surgical (P < 0.01) and non-surgical (P < 0.01) complication was significantly lower in the LG group than that in the OG group. The pooled analysis showed no significant difference in overall survival (OS) between LG and OG groups (P = 0.98). CONCLUSIONS LG can be a safe and feasible procedure for high-risk patients with gastric cancer.

Abstract
BACKGROUND Robot-assisted gastrectomy (RAG) has been increasingly used for the treatment of advanced gastric cancer (AGC), and many advantages over laparoscopy-assisted gastrectomy (LAG) have been reported. However, its postgastrectomy complications still under investigation and the results remain controversial. This study aimed to objectively assess the incidence and severity of complications following RAG vs. LAG using Clavien-Dindo (C-D) classification and to identify risk factors related to complications. METHODS Five hundred and twenty-seven patients with AGC who underwent RAG or LAG between January 2016 and May 2018 were enrolled in this study. Complications were categorized according to the C-D classification. The complications following RAG and LAG were compared using one-to-one propensity score matching (PSM) analysis and subgroup analyses. Logistic regression analyses were performed to identify risk factors related to complications. RESULTS RAG was performed in 251 patients (47.6%) and LAG in 276 patients (52.4%). Before PSM, the RAG group had a smaller tumour size (P = 0.004) and less patients with previous abdominal operation (P = 0.013). After PSM, a well-balanced cohort of 446 patients (223 in each group) was further analyzed. Of interest, the incidence of overall and severe complications (C-D grade ≥ IIIa) following the RAG group were significantly fewer than the LAG group (overall, 24.5% vs. 18.8%, P < 0.001; severe, 8.9% vs. 17.5%, P = 0.002). Subgroup analyses showed statistically significant difference were also observed in most stratified parameters. Multivariable analysis identified age ≥ 65 years, total gastrectomy, stage T3-T4a, stage II-III, and operation time ≥ 250 min as independent predictors of overall complications. Additionally, age ≥ 65 years, stage II-III, and operation time ≥ 250 min were confirmed as independent risk factors for severe complications. CONCLUSIONS RAG with D2 lymphadenectomy is feasible and safe for the treatment of AGC in terms of the lower incidence and severity of complications.

BACKGROUND The impact of postoperative complications (POCs) on the long-term survival outcomes after curative resection for gastric cancer has seldom been reported. The purpose of this study was to evaluate the relationship between the severity of POCs and long-term survival outcomes after curative resection for gastric cancer. METHODS The study analyzed 3091 patients who underwent curative resection for gastric cancer in a single center between June 2009 and June 2015. Patients were divided into two groups based on the occurrence or absence of postoperative complications which were recorded using the Clavien-Dindo classification. Long-term survival outcomes were compared between groups after propensity score matching (PSM). RESULTS A total of 3091 patients were included in the entire cohort. After PSM, no significant difference in baseline data was observed between the complications (C) group (n = 375) and no complications (NC) group (n = 375). With a median follow-up of 51 months, POCs were associated with decreased 5-year overall survival (OS) (51.7% vs. 67.5%, P < 0.001), disease-free survival (DFS) (49.9% vs. 65.6%, P < 0.001), and disease-specific survival (DSS) (53.9% vs. 68.8%, P < 0.001). Increasing Clavien-Dindo grades from II to IV was significantly associated with a corresponding decrease in OS (60, 48.3, 34%, P = 0.010), DFS (58.3, 46.3, 32.1%, P < 0.001) and DSS (62.9, 50.3, 34%, P < 0.001). Multivariate analysis confirmed POCs was an independent prognostic factor for decreased OS, DFS, and DSS (all P < 0.05). CONCLUSIONS POCs had a negative impact on long-term survival outcomes after curative resection for gastric cancer. The negative effects were also increased with higher Clavien-Dindo grades.

Long-term outcomes of laparoscopic versus open D2 gastrectomy for advanced gastric cancer. Surg Oncol 2018; 27:441-448. [PMID: 30217300 DOI: 10.1016/j.suronc.2018.05.022] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2018] [Revised: 05/11/2018] [Accepted: 05/25/2018] [Indexed: 12/23/2022]
Abstract
BACKGROUND Technical safety and short-term surgical outcomes of laparoscopy-assisted gastrectomy (LAG) for advanced gastric cancer (AGC) have been investigated in many clinical trials. However, studies with large sample size and sufficient follow-up comparing LAG and open gastrectomy (OG) for AGC have seldom been reported. The purpose of this study was to compare the long-term outcomes of LAG versus open OG for AGC using a propensity score matching analysis. METHODS We retrospectively evaluated 459 and 856 patients who underwent LG or OG with D2 lymph node dissection, respectively, for AGC between June 2007 and June 2012. One-to-one propensity score matching was performed to compensate for heterogeneity between groups. We compared long-term outcomes between the two groups after propensity score matching. RESULTS In the propensity score-matched cohort, no significant differences were observed in 5-year overall survival (OS) (52.0% vs. 53.4%; P = 0.805) and disease-free survival (DFS) (46.8% vs. 47.3%; P = 0.963) between the LAG group and OG group. Stratified analysis showed that the 5-year OS and DFS rates were comparable between the two groups in each tumor stage (P > 0.05). Multivariate analysis revealed that the operation method was not an independent prognostic factor for OS or DFS. Further analysis showed that the recurrence pattern was similar between the LAG group the OG group (P > 0.05). CONCLUSION LAG is a feasible surgical procedure for AGC in terms of long-term prognosis, although the results should be confirmed by the ongoing randomized controlled trials.
