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 was50.2±30.5months. 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 Background: Trophoblast cell-surface antigen 2 (TROP2) is a transmembrane glycoprotein expressed in epithelial cells. TROP2 overexpression has been reported to be correlated with malignant progression in most carcinomas, but TROP2 showed a tumor-suppressive function in some types of cancers. We currently developed a novel antibody against phospho-TROP2 (pTROP2). Since the function of TROP2 is controversial, we then aimed to clarify the clinicopathologic significance of TROP2 and pTROP2 expression in human gastric cancer (GC) in this study.Methods: We retrospectively analyzed the cases of 704 GC patients who underwent gastrectomy. The expressions of TROP2 and pTROP2 in each tumor were evaluated by immunohistochemistry. We analyzed the correlation between the GC patients' clinicopathologic features and the TROP2 and pTROP2 expression in their tumors.Results: Overexpression of TROP2 and that of pTROP2 were identified in 330 (46.9%) and 306 (43.5%) of the 704 GC patients, respectively. TROP2 overexpression was significantly correlated with the histological intestinal type, high tumor invasion depth (T3/T4), lymph node metastasis, lymphatic invasion, and venous invasion. In contrast, pTROP2 overexpression was significantly correlated with intestinal type, low tumor invasion depth (T1/2), no lymph node metastasis, and no lymphatic invasion. TROP2 overexpression was significantly associated with poorer overall survival (p<0.01, log rank), whereas pTROP2 overexpression was significantly associated with better overall survival (p<0.01, log rank).Conclusion: TROP2, but not pTROP2, might be associated with the metastatic ability of GC, resulting in poor prognoses for GC patients.

Abstract Background: Lymph node ratio (LNR), the ratio of metastatic lymph nodes to the total number of examined lymph nodes, has been considered a prognostic factor in gastric cancer (GC) patients. However, the predictive values of LNR vary as characteristics of patients are different. We confirmed its prognostic value and investigated the differences between patients with different pathological features.Methods: Totally, 211 GC patients who underwent curative gastrectomy between October 2004 and November 2016 were retrospectively investigated. Patients were classified into LNR 0, 1 and 2, using cutoff values 0.05 and 0.2. Cutoff values were calculated by Youden index. Relationships between LNR and clinicopathological characteristics were investigated by chi-square test or Fisher's exact test. Survival analysis were based on Cox proportional hazard regression model and Kaplan-Meier method.Results: LNR were related to tumor size (p = 0.003), Lauren classification (p = 0.007), grade of differentiation (p = 0.041), pT stage (p = 0.050) and pN stage (p < 0.001). In multivariable analysis, LNR was an independent prognostic factor (HR = 7.023, p < 0.001). In stratification analysis, LNR showed independent prognostic value (HR = 4.852, p < 0.001) in pT4 patients, but not in pT3 patients (p = 0.361) and pT1-2 patients (p = 0.123). Conclusions: LNR is an independent predictor of overall survival in pT4 GC patients who underwent curative surgery.

4561 Purpose: To determine the prognostic significance of the lymph node ratio (ratio of number of positive lymph nodes to number of dissected lymph nodes) in gastric cancer patients. Methods: We retrospectively analyzed 10,176 gastric patients from 1990–2003 who underwent curative gastrectomy from the SEER database. Survival curves were calculated according to the Kaplan-Meier method and analyzed with log-rank test. Multivariate analysis of prognostic factors related to survival was performed by the Cox proportional hazard model. Results: The lymph node ratio (LNR) was a strong predictor of survival. LNR was equally predictive of survival whether the analysis was restricted to patients with <15 lymph nodes dissected or >15 lymph nodes dissected. Survival of patients with a LNR of 0.1–5% was not significantly different than node negative patients; however, survival of patients with a LNR of 5–10% was significantly different than node negative patients. Multivariate analysis showed that LNR, T-stage, tumor size, and number of lymph nodes positive were independent prognostic predictors of death and that LNR was the strongest predictor for death. Multivariate analysis showed that the number of lymph nodes dissected was an independent prognostic factor for survival. Moreover, LNR was an independent prognostic factor for N1 and N2 patients by AJCC staging. LNR trended toward significance in AJCC N3 patients. Conclusions: LNR was the strongest predictor of death in gastric cancer patients when compared to T-stage, number of lymph nodes positive, and tumor size. LNR is equally predictive regardless of the adequacy of the lymph node dissection. No significant financial relationships to disclose.

Abstract Background: It is well established that retrieved lymph nodes (RLNs) count were positively correlated with better overall survival in gastric cancer (GC). But little is known about the relationship between RLNs count and short-term complications after radical surgery. Methods: A total of 1487 consecutive GC patients between January 2016 and December 2018 at Nanjing Drum Tower Hospital were retrospectively analyzed. Univariate analyses were performed to elucidate the association between RLNs count and postoperative complications. We further identified clinical factors that might affect the RLNs count.Results: Among all of the patients, postoperative complications occurred in 435 (29.3%) patients. The mean RLNs count was 25.1 and 864 (58.1%) patients were diagnosed with lymph node metastasis. Univariate analyses showed no significant difference between RLNs count and postoperative complications (both overall and stratified by CDC grade). We further explored that preoperative serum albumin, type of resection, operation time, tumor invasion, lymph node metastasis, and pTNM stage were associated with RLNs count. Conclusions: The current study demonstrated that RLNs count was not associated with postoperative short-term complications following gastrectomy of GC, which provided a rationale for the determination of a proper RLNs count of curative gastrectomy.
