World J Gastroenterol 2022; 28:381-398. [PMID: 35110956 PMCID: PMC8771610 DOI: 10.3748/wjg.v28.i3.381] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Revised: 11/09/2021] [Accepted: 01/10/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Surgery for gastric cancer is a complex procedure and lymphadenectomy is often mandatory. Postoperative mortality and morbidity after curative gastric cancer surgery is not insignificant.
AIM To evaluate the factors determining mortality and morbidity in a population of patients undergoing R0 resection and D2 lymphadenectomy for gastric cancer.
METHODS A retrospective analysis of clinical data and pathological characteristics (age, sex, primary site of the tumor, Lauren histotype, number of positive lymph nodes resected, number of negative lymph nodes resected, and depth of invasion as defined by the standard nomenclature) was conducted in patients with gastric cancer. For each patient we calculated the Kattan’s score. We arbitrarily divided the study population of patients into two groups based on the nomogram score (< 100 points or ≥ 100 points). Prespecified subgroups in these analyses were defined according to age (≤ 65 years or > 65 years), and number of lymph nodes retrieved (≤ 35 lymph nodes or > 35 lymph nodes). Uni- and multivariate analysis of clinical and pathological findings were performed to identify the factors affecting postoperative mortality and morbidity.
RESULTS One-hundred and eighty-six patients underwent a curative R0 resection with D2 lymphadenectomy. Perioperative mortality rate was 3.8% (7 patients); a higher mortality rate was observed in patients aged > 65 years (P = 0.002) and in N+ patients (P = 0.04). Following univariate analysis, mortality was related to a Kattan’s score ≥ 100 points (P = 0.04) and the presence of advanced gastric cancer (P = 0.03). Morbidity rate was 21.0% (40 patients). Surgical complications were observed in 17 patients (9.1%). A higher incidence of morbidity was observed in patients where more than 35 lymph nodes were harvested (P = 0.0005).
CONCLUSION Mortality and morbidity rate are higher in N+ and advanced gastric cancer patients. The removal of more than 35 lymph nodes does not lead to an increase in mortality.

Diagnostic evaluation of sentinel lymph node biopsy using indocyanine green and infrared or fluorescent imaging in gastric cancer: a systematic review and meta-analysis. Surg Endosc 2018; 32:2620-2631. [PMID: 29484554 DOI: 10.1007/s00464-018-6100-9] [Citation(s) in RCA: 36] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2017] [Accepted: 02/07/2018] [Indexed: 02/08/2023]
Abstract
BACKGROUND Sentinel node navigation surgery (SNNS) for gastric cancer using infrared visualization of indocyanine green (ICG) is intriguing because it may limit operative morbidity. We are the first to systematically review and perform meta-analysis on the diagnostic utility of ICG and infrared electronic endoscopy (IREE) or near infrared fluorescent imaging (NIFI) for SNNS exclusively in gastric cancer. METHODS A search of electronic databases MEDLINE, EMBASE, SCOPUS, Web of Science, and the Cochrane Library using search terms "gastric/stomach" AND "tumor/carcinoma/cancer/neoplasm/adenocarcinoma/malignancy" AND "indocyanine green" was completed in May 2017. Articles were selected by two independent reviewers based on the following major inclusion criteria: (1) diagnostic accuracy study design; (2) indocyanine green was injected at tumor site; (3) IREE or NIFI was used for intraoperative visualization. 327 titles or abstracts were screened. The quality of included studies was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2. RESULTS Ten full text studies were selected. 643 patients were identified with the majority of patients possessing T1 tumors (79.8%). Pooled identification rate, diagnostic odds ratio, sensitivity, and specificity were 0.99 (0.97-1.0), 380.0 (68.71-2101), 0.87 (0.80-0.93), and 1.00 (0.99-1.00), respectively. The summary receiver operator characteristic for ICG + IREE/NIFI demonstrated a test accuracy of 98.3%. Subgroup analysis found improved test performance for studies with low-risk QUADAS-2 scores, studies published after 2010 and submucosal ICG injection. IREE had improved diagnostic odds ratio, sensitivity, and identification rate compared to NIFI. Heterogeneity among studies ranged from low (I2 < 25%) to high (I2 > 75%). CONCLUSIONS We found encouraging results regarding the accuracy, diagnostic odds ratio, and specificity of the test. The sensitivity was not optimal but may be improved by a strict protocol to augment the technique. Given the number and heterogeneity of studies, our results must be viewed with caution.

Abstract
AIM: To compare the short- and long-term outcomes of vascularizing lymph node dissection (VLND) and non-vascularizing lymph node dissection (NVLND) from a single institution.
METHODS: Data of 315 patients with advanced gastric cancer who underwent standard D2 lymphadenectomy with curative intent was collected between January 1994 and December 2006. One hundred and fifty-two patients received VLND while 163 patients received NVLND. Short- and long-term clinical outcomes were compared between the two groups.
RESULTS: The median followed-up time was 82 mo. The rate of postoperative complications in the VLND group was 13.2%, while that in the NVLND group was 11.7% (P = 0.686). The overall 5-year survival rate was 64% in the VLND group and 59% in the NVLND group (P = 0.047). When subgroup analyses were performed according to Bormann type, type of differentiation and lymph node status, survival benefit was demonstrated in patients with Bormann type III or IV (59% vs 50%, P = 0.032), undifferentiated type (63% vs 49%, P = 0.021) or presence of lymph node metastasis (53% vs 38%, P = 0.010) in the VLND group.
CONCLUSION: D2 VLND in advanced gastric cancer treatment allows survival benefit with acceptable morbidity and mortality. VLND for patients with potentially curable advanced gastric cancer is feasible and safe when performed by a well-trained surgical team.

The prognostic value of lymph nodes dissection number on survival of patients with lymph node-negative gastric cancer. Gastroenterol Res Pract 2014; 2014:603194. [PMID: 24868201 PMCID: PMC4020362 DOI: 10.1155/2014/603194] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2014] [Accepted: 04/02/2014] [Indexed: 02/07/2023] Open
Abstract
Objective. The study was designed to explore the prognostic value of examined lymph node (LN) number on survival of gastric cancer patients without LN metastasis. Methods. Between August 1995 and January 2011, 300 patients who underwent gastrectomy with D2 lymphadenectomy for LN-negative gastric cancer were reviewed. Patients were assigned to various groups according to LN dissection number or tumor invasion depth. Some clinical outcomes, such as overall survival, operation time, length of stay, and postoperative complications, were compared among all groups. Results. The overall survival time of LN-negative GC patients was 50.2 ± 30.5 months. Multivariate analysis indicated that LN dissection number (P < 0.001) and tumor invasion depth (P < 0.001) were independent prognostic factors of survival. The number of examined LNs was positively correlated with survival time (P < 0.05) in patients with same tumor invasion depth but not correlated with T1 stage or examined LNs >30. Besides, it was not correlated with operation time, transfusion volume, length of postoperative stay, or postoperative complication incidence (P > 0.05). Conclusions. The number of examined lymph nodes is an independent prognostic factor of survival for patients with lymph node-negative gastric cancer. Sufficient dissection of lymph nodes is recommended during surgery for such population.

Abstract
INTRODUCTION Gastric cancer is the second leading cause of cancer death in the world. The objective of this study was to present the clinical evaluation, treatment and outcome of 179 patients with gastric carcinoma in Zaria, Nigeria. METHODS Patients managed for histologically diagnosed gastric carcinoma were reviewed. The extent of surgical intervention was based on pre-operative and intra-operative staging balanced against the age and overall fitness of the patient. Mortality, morbidity and patient's survival were monitored. RESULTS There were 179 patients, with a male to female ratio of 1.4:1. Their mean age was 51 ± 6.3. Ten (5.6%) patients presented with early gastric cancer. Overall, 155(86.6%) patients had surgical intervention including gastric resection in 87 (56.1%). Of the gastrectomies , 28.7% were curative (R0). Postoperative complications were seen in 43(27.7%) patients. Postoperative mortality in 25(16.1%) patients was significantly associated with peritoneal metastasis (p<0.001), preoperative comorbidity (p<0.01) and age more than 60 years (p<0.03). The overall median survival was 13.6 months while 70.1% and 21.8% of patients that underwent gastrectomy survived for 1 and 5 years respectively. CONCLUSION Treatment of gastric cancer should be based on a reasonable choice of operation that must consider not only the survival benefits but also the surgical risks and postoperative quality of life.

The effectiveness of the new (7th) UICC N classification in the prognosis evaluation of gastric cancer patients: a comparative study between the 5th/6th and 7th UICC N classification. Gastric Cancer 2011; 14:166-71. [PMID: 21360132 DOI: 10.1007/s10120-011-0024-6] [Citation(s) in RCA: 73] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2010] [Accepted: 12/14/2010] [Indexed: 02/07/2023]
Abstract
BACKGROUND The most important prognostic factor after curative surgery for gastric carcinoma is the presence of lymph node metastases. According to the 7th edition of the UICC TNM staging system for gastric cancer, N classification was categorized as N0 (no regional lymph node metastasis), N1 (1-2 regional lymph node metastases), N2 (3-6 regional lymph node metastases), and N3 (7 or more regional lymph node metastases). The purpose of this study was to evaluate the rationality of the new UICC/AJCC N classification in comparison with the 6th UICC classification. METHODS From August 2002 to July 2006, 295 patients with gastric cancer underwent curative resection with D2 lymph node dissection by a single surgeon. We analyzed retrospectively the significant prognostic factors and identified the suitability of the 7th UICC N staging system. RESULTS According to the 7th UICC N classification, the 5-year cumulative survival rates (5-YSR) of N0, N1, N2, N3a, and N3b were 89.7, 73.6, 54.9, 23.1, and 5.4%, respectively (P < 0.0001). Using univariate analysis, the N classification of the 7th and 6th UICC/AJCC TNM staging system, T classification of the 7th UICC TNM staging system, size and location of tumor, and histology were associated with the overall survival of gastric cancer after curative surgery. However, Cox regression multivariate analysis showed the 7th UICC N classification was an independent prognostic factor instead of the 6th UICC N classification (P < 0.0001). CONCLUSION The 7th UICC classification for lymph node metastasis is thought to be a more reliable prognostic factor for gastric cancer than the 6th classification.
