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.

Surg J (N Y) 2023; 9:e28-e35. [PMID: 36742159 PMCID: PMC9897905 DOI: 10.1055/s-0043-1761278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 12/05/2022] [Indexed: 02/05/2023] Open
Abstract
Introduction Multivisceral resections (MVRs) in gastric cancer are potentially curable in selected patients in whom clear resection margins are possible. However, there are still uncertain data on their feasibility and safety considering short- and long-term results. The study compares survival, morbidity, mortality, and other secondary outcomes between standard and MVRs for gastric cancer. Materials and Methods A monocentric retrospective study in patients with gastric adenocarcinoma, covering 2004 to 2020. Of the 336 operable cases, 101 patients underwent MVRs. The remaining 235 underwent standard gastric resections (SGRs), of which 173 patients were in stage T3/T4. To compare survival, a control group of 101 patients with palliative procedures was used-bypass anastomosis or exploration. Results MVR had a lower survival rate than the SGR but significantly higher than the palliative procedures. The predominant gender in MVR was male (72.3%), with a mean age of 61 years. The perioperative mortality was 3.96% ( n = 4), and the overall median survival was 28.1 months. The most frequently resected organs were the spleen (67.3%), followed by the pancreas (32.7%) and the liver (20.8%). In 56.4% of the cases two organs were resected, in 28.7% three organs, and in 13.9% four organs. The main complication was bleeding (9.9%). The major postoperative complications in the MVR were 14.85%, and in the SGR 6.4% ( p < 0.05). Better long-term results were observed in patients who underwent R0 resections compared with R1. Conclusion Multiorgan resections are characterized by poorer survival and a higher complication rate than gastrectomies. On the other hand, they have better long-term outcomes than palliative procedures. However, MVRs are admissible when performed by an experienced surgical team in high-volume centers.

Efficacy and safety of FLOT regimen vs DCF, FOLFOX, and ECF regimens as perioperative chemotherapy treatments for resectable gastric cancer patients; a report from the middle east. Res Pharm Sci 2022; 17:621-634. [PMID: 36704436 PMCID: PMC9872182 DOI: 10.4103/1735-5362.359430] [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: 05/15/2022] [Revised: 08/13/2022] [Accepted: 08/23/2022] [Indexed: 01/28/2023] Open
Abstract
Background and purpose This study aimed to compare the efficacy and toxicity of perioperative chemotherapy regimens including epirubicin, cisplatin, 5-fluorouracil (ECF), docetaxel, cisplatin, 5-fluorouracil (DCF), leucovorin, 5-fluorouracil, oxaliplatin (FOLFOX), and 5-fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) to identify the most effective chemotherapy regimen with less toxicity. Experimental approach This retrospective cohort study (2014-2021) was based on 152 eligible resectable gastric cancer patients who had received one of the perioperative mentioned chemotherapy regimens and followed for at least two years. The primary endpoint of this study was overall survival (OS), progression-free survival (PFS), overall response rate (ORR), and R0 resection. Findings / Results Of included patients, 21%, 33.7%, 24.3%, and 21% had received ECF, DCF, FOLFOX and FLOT, respectively. After the median 30-month follow-ups, OS was higher with the FLOT regimen in comparison with other regimens (hazard ratio = 0. 276). The median OS of the FLOT regimen was 39 months. Besides, the median OS was 28, 25, and 21 months for DCF, FOLOFX, and ECF regimens, respectively. Moreover, a median PFS of 24, 18, 17, and 14 months was observed for FLOT, DCF, FOLFOX, and ECF regimens, respectively (Log-rank < 0.001). FLOT regimen showed 84. 4% ORR which was notably higher than other groups. Conclusions and implications For resectable gastric cancer patients, the perioperative FLOT regimen led to a significant improvement in patients' OS and PFS versus ECF, DCF, and FOLFOX regimens. As such, the FLOT regimen could be considered the optimal option for managing resectable gastric cancer patients.

Abstract
Background: T4a gastric cancer (GC) is a subtype of advanced GC (AGC), which urgently needs a comprehensive grade method for better treatment strategy choosing. The purpose of this study was to develop two nomograms for predicting the prognosis of patients with T4a GC. Methods: A total of 1,129 patients diagnosed as T4a GC between 2010 and 2015 were extracted from the Surveillance, Epidemiology, and End Result (SEER) program database. Univariate and multivariate Cox analyses were performed to explore the independent predictors and to establish nomogram for overall survival (OS) of the patients, whereas competing risk analyses were performed to find the independent predictors and to establish nomogram for cancer-specific survival (CSS) of the patients. The area under the curve (AUC), calibration curve, decision curve analysis (DCA), and Kaplan–Meier analysis were performed to evaluate the nomograms. Results: Older age, larger tumor size, black race, signet ring cell carcinoma (SRCC), more lymph node involvement, the absence of surgery, the absence of radiotherapy, and the absence of chemotherapy were identified as independent prognostic factors for both OS and CSS. In the training cohort, the AUCs of the OS nomogram were 0.760, 0.743, and 0.723 for 1-, 3-, and 5-year OS, whereas the AUCs of the CSS nomogram were 0.724, 0.703, and 0.713 for 1-, 3-, and 5-year CSS, respectively. The calibration curve and DCA indicated that both nomograms can effectively predict OS and CSS, respectively. The abovementioned results were also confirmed in the validation cohort. Stratification of the patients into high- and low-risk groups highlighted the differences in prognosis between the two groups both in training and in validation cohorts. Conclusions: Age, tumor size, race, histologic type, N stage, surgery status, radiotherapy, and chemotherapy were confirmed as independent prognostic factors for both OS and CSS in patients with T4a GC. Two nomograms based on the abovementioned variables were constructed to provide more accurate individual survival predictions for them.

Radiologic serosal invasion sign as a new criterion of T4a gastric cancer on computed tomography: diagnostic performance and prognostic significance in patients with advanced gastric cancer. Abdom Radiol (NY) 2020; 45:2950-2959. [PMID: 31359095 DOI: 10.1007/s00261-019-02156-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/16/2022]
Abstract
PURPOSE To investigate the diagnostic performance and prognostic significance of a new criterion for radiologic T4a staging on computed tomography (CT) in patients with advanced gastric cancer (AGC). METHODS Between January 2010 and April 2019, 101 patients with pathologically confirmed gastric cancer were collected. Among them, 53 patients with pathologic T3 and T4a cancers were included in this study. Three reviewers assessed preoperative CT scans for radiologic T staging in two sessions, independently and in consensus at a 2-week interval, while blinded about the pathologic T stage. The radiologic serosal invasion sign was defined as a nodular extension from the outer gastric wall reaching beyond the perigastric vascular plane and adopted as a new CT criterion for T4a cancer. We evaluated the diagnostic performance, interobserver agreement, and prognostic significance of this sign for the postoperative recurrence. RESULTS There were 46 pathologic T3 cancers (86.7%) and seven pathologic T4a cancers (13.2%). The diagnostic performance of the radiologic serosal invasion sign in the differentiation between T3 and T4a cancers was as follows: sensitivity, 91.3%; specificity, 71.43%; and accuracy, 88.68% for R1 and sensitivity, 78.26%; specificity, 85.71%; and accuracy, 79.25% for R2. The k-value was 0.64. Among the clinical and pathologic variables, radiologic T4a sign [hazard ratio (HR): 7.96; 95% confidence interval (CI) 2.36-26.86, p = 0.001], pathologic T4a (HR 9.82, 95% CI 2.35-40.95, p = 0.002), tumor size (HR 1.18, 95% CI 1.02-1.35, p = 0.026), and lymphovascular invasion (HR 6.39, 95% CI 1.42-28.75, p = 0.015) were the significant factors for postoperative recurrence. CONCLUSIONS Radiologic serosal invasion sign is reliable as a new CT criterion for T4a cancer staging in patients with advanced gastric cancer, demonstrating 80% to 88% accuracy. Radiologic serosal invasion sign can also serve as a prognostic factor for postoperative recurrence as well as pathologic T4a stage.

Abstract
INTRODUCTION Multivisceral resection (MVR) is potentially curative for selected gastric cancer patients, supposedly at the cost of increased complications. However, current data comparing MVR to standard gastrectomy (SG) is lacking. OBJECTIVES Compare complications and survival after MVR and SG. METHODS In a retrospective cohort of 1015 patients with gastric adenocarcinoma, 58 underwent MVR and 466 SG. Groups were compared concerning their characteristics, complications, and survival. RESULTS One hundred seventy-six patients had postoperative complications. Major complications were more frequent after MVR (P = .002). Surgical mortality was 8.6% and 4.9% for MVR and SG (P = .221). Older age, higher morbidities, and MVR were independent risk factors for major complications. The odds ratio for major complications was 5.89 for MVR with one or two organs and 38.01 for MVR with three or more organs. The pancreas was the most commonly removed organ and pT4b disease were confirmed in 34 (58.6%) of the MVR cases. Disease-free survival (DFS) was lower in MVR patients (51% vs 77.8%; P < .001), being worse according to the number of organs resected. In pN+ patients, DFS was worse after MVR. DFS was equivalent to pT4b and non-pT4b in the MVR group. CONCLUSIONS Increased morbidity and lower survival are expected for gastric cancer patients undergoing MVR.

Abstract
PURPOSE This study reports single-surgeon experience with extended gastrectomy including en-bloc resection of adjacent organs/structures for T4b stage gastric adenocarcinoma. Time-related changes in patient selection criteria and outcomes were also analyzed. METHODS All consecutive gastrectomies for adenocarcinoma performed between May 2004 and December 2017 were extracted from prospectively collected database to study surgical and oncologic results. Time-related changes in outcomes were examined according to three time periods. RESULTS Five hundred eighty-seven gastrectomies were performed throughout the study period including 87 (14.8%) extended resections. The latter most often included pancreatosplenectomy, colon, and liver resections (21, 16, and 11 patients, respectively) resulting in similar postoperative outcomes and survival. Extended gastrectomy was associated with larger tumor size (8.4 vs 5.6 cm), performing total gastrectomy (55.2 vs 35.2%, p < 0.01) and increased blood loss (375 vs 150 ml, p < 0.01) compared with standard gastrectomy. Larger experience in extended gastrectomy allowed for expanding patient selection criteria, considering complex resections and extensive lymphadenectomy. Median and 3-year survival following extended gastrectomy for T4b adenocarcinoma were 14 months and 18%, respectively, which was comparable to standard gastrectomy for T4a adenocarcinoma (p = 0.48). Obesity, nodal stage and type of gastrectomy were associated with survival in T4b adenocarcinoma in the univariable analysis. Obesity and N3a and N3b stages were independent predictors in the multivariable model. CONCLUSIONS Extended gastrectomy for T4b gastric adenocarcinoma provides satisfactory surgical outcomes even with expanded patient selection criteria and regardless of the organ involved. Given its poor prognosis, neoadjuvant therapy should be considered to improve the long-term oncologic results.

Abstract
Background: To investigate prognostic factors and recurrence patterns in T4 gastric cancer (GC) patients after curative resection. Methods: Between January 2004 and December 2014, 249 patients with T4 gastric cancer undergoing curative resection were recruited. Patient characteristics, survival, prognostic factors and recurrence patterns were analyzed. Results: Our results showed that the median survival time (MST) for T4 gastric cancer after curative resection was 55.47 months, with 59.47 months for T4a (tumor perforating serosa) and 25.90 months for T4b (tumor invasion of the adjacent structure). Multivariate analysis indicated that age (hazard ratio [HR], 1.86; P = 0.006), location of tumor (HR, 1.25, 0.90 - 5.64; P < 0.001) and intraoperative blood loss (HR, 1.85; P = 0.010) were independent prognostic factors for overall survival (OS). After a median follow-up of 25.87 months, a total of 109 (43.8%) patients suffered from recurrence, and 90 patients had been observed specific recurrence sites, among which peritoneal metastasis was the most common recurrence pattern, 59.0% for T4a and 88.3% for T4b, respectively. Conclusions: For T4 gastric cancer patients after curative resection, older age, gastric cancer of the entire stomach and more intraoperative blood loss were associated with poor OS. The recurrence rate after curative resection for T4 was high, and the most common recurrence pattern was peritoneal metastasis.

Abstract
AIM To study the prognostic factors of gastric cancer (GC) patients who were classified with stage III disease according to the newest TNM classification. METHODS This study retrospectively enrolled 279 patients who underwent radical gastrectomy from January 2012 to December 2014 at our hospital and who were diagnosed with stage III GC according to the new 8th edition of the TNM classification. The patient data that were collected included age, sex, pathological parameters, survival, lymph node ratio, neo-adjuvant chemotherapy with oxaliplatin and S-1, and operation type. The characteristics, survival, and prognostic factors of the patients were analyzed by univariate and multivariate analyses. RESULTS The median OS of the patients after curative surgery was 19 months, and the 3-year survival rate (3-YSR) was 25.3%. A univariate analysis showed that tumor location (P = 0.01), neo-adjuvant chemotherapy (P = 0.005), pathological T stage (P = 0.002), pathological N stage (P < 0.001), lymph node ratio (LNR) (P < 0.001), and operation type (P = 0.032) were significantly associated with overall survival. A multivariate analysis revealed that neo-adjuvant chemotherapy (P = 0.009), pathological T stage (P = 0.012), and LNR (P < 0.001) were independent prognostic factors. CONCLUSIONS Neo-adjuvant chemotherapy, pathological T stage, and LNR were independent prognostic factors for the overall survival of patients with stage III GC. The neo-adjuvant chemotherapy with oxaliplatin and S-1 can be used for the patients to improve their survival.

Abstract
BACKGROUND The prognosis and survival of patients with advanced gastric cancer is poor. Although completeness of resection (R0) is one of the most important factors affecting survival, multivisceral resection (MVR) for locally advanced (clinical T4b, cT4b) gastric cancer remains controversial. The aim of this study was to evaluate the factors affecting prognosis and survival after MVR in patients with cT4b gastric cancer. METHODS Between 2005 and 2015, we retrospectively reviewed the medical records of 103 patients who underwent MVR for cT4b gastric cancer with suspected direct invasion to adjacent organs. Patient characteristics, related complications, long-term survival, and prognostic factors of cT4b gastric cancer were analyzed. RESULTS Postoperative mortality and morbidity rates of patients after MVR were 1.0 and 37.9%, respectively. R0 resection was achieved in 82.5% patients, all of whom had a significantly improved survival rate. Overall survival rates at 1 and 3 years were 78.3 and 47.7% for R0 resection and 46.6 and 14.3% for R1 resection, respectively (R0 vs. R1, P < 0.002). Multivariate analysis revealed that completeness of resection (R0) was an independent prognostic factor associated with longer survival. CONCLUSIONS In patients with cT4b gastric cancer, gastrectomy with MVR to achieve an R0 resection can be performed with acceptable postoperative morbidity and mortality rates and can have a positive impact on long-term survival.

Incomplete resection and linitis plastica are factors for poor survival after extended multiorgan resection in gastric cancer patients. Sci Rep 2017; 7:15800. [PMID: 29150634 PMCID: PMC5694005 DOI: 10.1038/s41598-017-16078-x] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Accepted: 11/07/2017] [Indexed: 12/12/2022] Open
Abstract
The aim of this retrospective study was to analyze the morbidity, mortality, and survival rates of extended multiorgan resection (EMR) for locally advanced gastric cancer patients compared to gastrectomy alone and a palliative operation. 893 locally advanced gastric cancer patients without distant metastasis had surgery including gastrectomy alone (GA group, n = 798), EMR resection (EMR group, n = 75), and palliative operation (palliative gastrectomy or gastrojejunostomy (PO group, n = 20)). Postoperative mortality and complication rates in the EMR group were significantly higher than in the GA group (2.7% vs 0.4%, P = 0.010 and 25.3% vs 8.1%, P < 0.001, respectively), but similar in the PO group. The median survival time of the EMR group was significantly longer than in the PO group (27 months vs 11 months, P = 0.020), but significantly worse (P = 0.020) than in the GA group (44 months). Incompleteness of resection (R1) and linitis plastica were independent prognostic factors for survival in the EMR group. Three different gastric cancer surgeries led to different postoperative mortality and complication rates. EMR had a better survival rate compared with PO while GA had the longest survival time with the lowest mortality and complication rates.

Abstract
There are plenty of risk factors associated with splenic hilar lymph node metastasis (SHLNM) in patients with advanced gastric cancer (AGC). Whereas, their main influencing factors have not reached a consensus yet. The aim of the study is to investigate the related clinicopathological factors influencing SHLNM in AGC. A retrospective study was performed to investigate 150 patients who underwent D2 curative partial or total gastrectomy for gastric carcinoma from January 2007 to November 2012. Clinicopathological factors were analyzed by univariate and multivariate analysis. A total of 10.7% (16/150) of the patients had SHLNM. The overall ratio of metastatic lymph node (positive lymph nodes/lymph nodes harvested) in the splenic hilum was 17.5% (38/217). Univariate analysis results showed SHLNM was related with depth of invasion, tumor grade, tumor size, tumor location and Bormann type, with significant difference (P<0.05); Multivariate analysis demonstrated that SHLNM was related with depth of invasion and tumor size, with significant difference (P<0.05). Consequently, depth of invasion, tumor grade, tumor size, tumor location and Bormann type were associated with SHLNM in AGC, meanwhile depth of invasion and tumor size are independent risk factors. Preoperative predicting risk factors of SHLNM greatly benefits making more rational surgical scheme of treating AGC.

[PMID: 26372042 PMCID: PMC4570799 DOI: 10.1371/journal.pone.0136871] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2015] [Accepted: 08/10/2015] [Indexed: 01/31/2023] Open
Abstract
This study investigated the utility of quantifying iodine concentration (IC) in perigastric adipose tissue, using dual-energy computed tomography (DECT), for the detection of T4a-stage gastric cancer. Fifty-four patients with gastric cancer were enrolled at the Fourth Hospital of Hebei Medical University between January and June 2013. Patients were imaged preoperatively with conventional computed tomography (CT) scans and DECT, and the IC in perigastric fat adjacent to the tumor calculated from arterial phase (AP) and portal venous phase (PVP) images. The patients subsequently received surgical treatment (gastrectomy), and histologic analysis of resected specimens was used as a ‘gold standard’ reference for cancer staging. Receiver operating characteristic (ROC) curve analysis was employed to assess the utility of DECT for identifying T4a-stage gastric cancer, with optimal IC thresholds determined from the area under the ROC curve (AUC). Postoperative histology revealed that 32 patients had serosal invasion (group A), and 22 did not (group B). The accuracy of conventional CT for distinguishing stage T4 from non-T4 stages was 68.5% (37/54). IC was significantly higher in group A than in group B (AP: 0.60±0.34 vs. 0.09±0.19 mg/mL, p<0.001; PVP: 0.83±0.41 vs. 0.27±0.21 mg/mL, p<0.001). The sensitivity, specificity and AUC for detecting serosal invasion were 77.1%, 79.2% and 0.89 at an IC threshold of 0.25 mg/mL for AP images; and 80.0%, 79.2% and 0.90 at an IC threshold of 0.45 mg/mL for PVP images. These results indicated that Iodine quantification in perigastric fat using DECT is an accurate method for detecting serosal invasion by gastric cancer.

Mol Med Rep 2014; 11:1366-71. [PMID: 25369757 DOI: 10.3892/mmr.2014.2839] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2014] [Accepted: 09/29/2014] [Indexed: 11/06/2022] Open
Abstract
Stimulation of Toll‑like receptor 9 (TLR9) has been associated with invasion in various types of cancer cell in vitro. The present study aimed to evaluate the expression of TLR9 in MGC803 gastric cancer cells and investigate the effect of a non‑specific TLR9 inhibitor, chloroquine (CQ), on MGC803 cell migration via the TLR9/nuclear factor kappa B (NFκB) signaling pathway. The expression of TLR9 was investigated using reverse transcription polymerase chain reaction (RT‑PCR), flow cytometry and western blot analysis. The effects of CQ on MGC803 cell proliferation were measured by MTT colorimetric assay. The mRNA expression levels of cyclooxygenase‑2 (COX‑2), matrix metalloproteinase (MMP)‑2, MMP‑7 and NFκB p65 were evaluated by RT‑PCR in MGC803 cells stimulated by various concentrations of CQ. The migration of gastric cancer cells treated with CQ at 12, 24 and 36 h was measured by wound healing assay. The results indicated that MGC803 cells expressed TLR9 and that CQ had anti‑proliferative effects on MGC803 cells and inhibited mRNA expression of COX‑2, MMP‑2, MMP‑7 and NFκB p65 (P<0.05). Furthermore, CQ inhibited the bioactivity of NFκB p65 and prevented the migration of MGC803 cells in a dose‑dependent manner (P<0.05). In conclusion, the results indicated that the TLR9/NFκB signaling pathway was involved in gastric cancer cell migration and that CQ had anti‑tumor activity.
