Objective To understand role of chemokines and their receptors in pathogenesis, progression, and metastasis of gastric cancer, and to provide a better approach for diagnosis and treatment of gastric cancer. Method The literatures about the relationship between chemokines and their receptors and gastric cancer were reviewed. Results There were about 50 various chemokines and their receptors abnormally expressed in the tumor microenvironment. The main types related gastric cancer were the CXC, CC and CX3C chemokines and their receptors, which could promote the proliferation, invasion, and metastasis of the gastric cancer through several pathways like mTOR pathway, JAK2-STAT3 pathway, etc.. Conclusions Chemokines and their receptors play an important role in occurrence and development of gastric cancer. Further studies on chemokines and their receptors will not only assist in early diagnosis of gastric cancer, as well as estimation of clinical prognosis, but also provide an intervention target for gastric cancer.
Objective To study the necessity and feasibility of No.12b lymph node dissection in D2 lymphadenectomy for advanced distal gastric cancer, and the relation between No.12b lymph node metastasis and clinicopathologic factors. Methods Clinical data of sixty cases of advanced distal gastric cancer receiving D2 or D2+ radical correction were collected retrospectively, both of which were all plus No.12b lymph node dissections. The relationships between No.12b lymph node metastasis and clinicopathologic factors were analyzed. Results No death attributed to operation or severe operative complications were found. There were 12 cases (20.00%) with No.12b lymph node metastasis. The rates of No.12b lymph node metastasis in Borrmann Ⅲ-Ⅳ types, N2-3 of lymph node metastasis and T3-4 of tumor infiltration were 31.25% (10/32), 30.30% (10/33) and 29.73% (11/37), which were significantly higher than those in Borrmann Ⅰ-Ⅱ types 〔7.14% （2/28）〕, N0-1 〔7.41% （2/27）〕 and T1-2 〔4.35% （1/23）〕 respectively (Plt;0.05). There was no relationship between tumor size and No.12b lymph node metastasis. Conclusions No.12b lymph node dissection is safe and feasible for advanced distal gastric cancer. Further perspective studies on No.12b lymph node dissection influence on prognosis in more cases are required.
ObjectiveTo investigate the relationship between topical reactive lymphoid hyperplasia and postoperative recurrence and survival of gastric cancer patients. MethodsThe clinical and pathological data of gastric cancer patients who underwent D2 radical gastrectomy from January 2007 to July 2009 were retrospectively analyzed. Based on the number of reactive lymph nodes, cases were divided in to topical reactive lymphoid hyperplasia group (RLH, n=18) and non-RLH group (n=43) by using a median method. The postoperative disease-free survival (DFS) and overall survival (OS) rates of patients in different groups were compared using Kaplan-Meier method and log-rank test, respectively. ResultsThere were no significant difference between the two groups in age, gender, pathological stage, surgical approach, extent of surgery or methods of postoperative chemotherapy (P > 0.05). The median disease-free survival time was 50 months in RLH group, and the median disease-free survival time was 39 months in non-RLH group. DFS of patients in RLH group was significant higher than non-RLH group (66.7% vs. 34.9%, P=0.048). The median survival time was 53.6 months and 52.3 months, respectively, in RLH group and non-RLH group. No difference was found in OS between the two groups (72.2% vs. 60.5%, P=0.338). ConclusionTopical reactive lymphoid hyperplasia reactive the immunity of gastric cancer patients and contact postoperative DFS rate.
Objective To assess safety and feasibility of laparoscopic gastrectomy in the elderly with gastric cancer. Methods From January 2010 to September 2014, 146 elderly (age ≥65 years old) patients with gastric cancer underwent radical operations in the Department of General Surgery, Guangdong Academy of Medical Sciences and Guangdong General Hospital were collected, then were divided into a laparoscopy-assisted radical gastrectomy (LAG group, n=40) and an open radical gastrectomy (OG group, n=106) according to the operative mode. The differences of intraoperative and postoperative situation, and the postoperative complications were analyzed between the LAG group and the OG group. Results ① The age, gender, body mass index, albumin, ASA grade, tumor location, differentiation degree, TNM stage, radical gastrectomy, and digestive tract anastomosis had no significant differences between the LAG group and the OG group (P>0.05). ② None of the patients died during the operative period and there was no significant difference in the mean number of retrieved lymph nodes between these two groups (P>0.05). In the aspects of the intraoperative blood loss, the first flatus time or the first feeding time, and the postoperative hospitalization stay in the LAG group were significantly less than those in the OG group (P<0.05). For the operative time, the OG group showed a distinctive advantage with a significantdifference than the LAG group (P<0.05). ③ The rate of postoperative complication in the LAG group and OG group was 10.0% (4/40) and 15.1% (16/106) respectively, and the difference was not significant (χ2=0.64, P=0.591), the grade of the Clavien-Dindo complications had no significant difference (χ2=0.63, P=0.592). ④ None of the patients died following operation in the LAG group and one case died in the OG group because of the respiratory and circulatory failure caused by the pulmonary embolism. Conclusion Preliminary results of limited cases in this study show that LAG in the elderly patients with gastric cancer could reduce intraoperative blood loss, shorten the first flatus time or the first feeding time, and postoperative hospitalization stay, could obtain same radical effect without increasing incidence of postoperative complications as compared with OG, so it is safety and feasible.
ObjectiveTo investigate the effects of intraoperative intermittent pneumatic compression (IPC) treatment on coagulation and fibrinolysis, lower extremity venous blood flow velocity, and deep venous thrombosis (DVT) in patients with gastric cancer (GC) after radical gastrectomy. MethodsThe patients with GC who underwent radical gastrectomy at Hebei Provincial People’s Hospital from July 2021 to July 2024 were retrospectively enrolled, then the patients were assigned into control group (the patients who did not receive intraoperative IPC) and study group (the patients who received intraoperative IPC), and the propensity score matching (PSM) method was used to conduct 1∶1 matching based on the basic characteristics such as age, gender, body mass index, comorbidities to ensure baseline comparability between the two groups. The incidences of postoperative DVT and lower extremity swelling, and coagulations [prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT)] and fibrinolysis [D-dimer (D-D), fibrinogen (FIB), and fibrin degradation products (FDP)], as well as lower extremity venous blood flow velocity were analyzed after PSM. The locally weighted regression was used to analyze the correlation between the coagulation and fibrinolytic functions indexes and the lower extremity venous blood flow velocity. ResultsA total of 120 patients were matched (60 cases per group). The baseline characteristics of both groups were comparable (P>0.05). The incidences of DVT on day 7 and lower extremity swelling on day 1, 3, and 7 after surgery in the study group were significantly lower than those in the control group (P<0.05). The results of repeated-measures analysis of variance showed that there were statistically significant differences in the inter-group, time-related, and group-by-time interaction effects of coagulation and fibrinolysis indexes as well as lower extrimety venous blood flow velocities (P<0.05). The impact of the time factor on coagulation and fibrinolysis indexes and lower extrimety venous blood flow velocities varied with intraoperative IPC intervention measures. After surgery, the PT, TT, APTT, and lower extrimety venous blood flow velocities in the study group first decreased and then increased as compared with those before surgery, and the decrease degree was smaller and the increase degree was larger than those in the control group. After surgery, the D-D, FIB, and FDP in the study group first increased and then decreased as compared with those before surgery, and the increase degree was smaller and the decrease degree was larger than those in the control group. Both PT and TT were significantly positively correlated with femoral vein blood flow velocity (r=0.21, P=0.042; r=0.22, P=0.040), and both also showed significant positive correlations with popliteal vein blood flow velocity (r=0.25, P＜0.001; r=0.20, P=0.032). APTT was only significantly positively correlated with popliteal vein blood flow velocity (r=0.33, P＜0.001). D-D was negatively correlated with the flow velocities of the femoral vein, external iliac vein, and popliteal vein (r=–0.23, P=0.012; r=–0.22, P=0.047; r=–0.37, P<0.001). Both FIB and FDP were negatively correlated with the flow velocity of the femoral vein (r=–0.23, P=0.036; r=–0.27, P=0.002). FIB was also negatively correlated with the flow velocity of the popliteal vein (r=–0.26, P=0.038), and FDP was negatively correlated with the flow velocity of the external iliac vein (r=–0.31, P<0.001). ConclusionBased on the results of this study, intraoperative IPC treatment could improve coagulation and fibrinolytic functions of patients with GC after surgery, and has a certain preventive effect on occurrence DVT of lower extremity.
ObjectiveTo investigate the risk factors affecting the occurrence of infectious complications after radical gastrectomy for gastric cancer, and to establish a risk prediction Nomogram model. MethodsThe clinicopathologic data of 429 primary gastric cancer patients who underwent radical resection for gastric cancer at the Second Department of General Surgery of Shaanxi Provincial People’s Hospital between January 2018 and December 2020 were retrospectively collected to explore the influencing factors of infectious complications using multivariate logistic regression analyses, and to construct a prediction model based on the results of the multivariate analysis, and then to further validate the differentiation, consistency, and clinical utility of the model. ResultsOf the 429 patients, infectious complications occurred in 86 cases (20.05%), including 53 cases (12.35%) of pulmonary infections, 16 cases (3.73%) of abdominal infections, 7 cases (1.63%) of incision infections, and 10 cases (2.33%) of urinary tract infections. The results of multivariate logistic analysis showed that low prognostic nutritional index [OR=0.951, 95%CI (0.905, 0.999), P=0.044], long surgery time [OR=1.274, 95%CI (1.069, 1.518), P=0.007], American Society of Anesthesiologists physical status classification (ASA) grade Ⅲ–Ⅳ [OR=9.607, 95%CI (4.484, 20.584), P＜0.001] and alcohol use [OR=3.116, 95%CI (1.696, 5.726), P＜0.001] were independent risk factors for the occurrence of infectious complications, and a Nomogram model was established based on these factors, with an area under the ROC of 0.802 [95%CI (0.746, 0.858)]; the calibration curves showed that the probability of occurrence of infectious complications after radical gastrectomy predicted by the Nomogram was in good agreement with the actual results; the decision curve analysis showed that the Nomogram model could obtain clinical benefits in a wide range of thresholds and had good practicality.ConclusionsClinicians need to pay attention to the perioperative management of gastric cancer patients, fully assess the patients’ own conditions through the prediction model established by prognostic nutritional index, surgery time, ASA grade and alcohol use, and take targeted interventions for the patients with higher risks, in order to reduce the risk of postoperative infectious complications.
