Prognostic impact of splenectomy on advanced proximal gastric cancer with No. 10 lymph node metastasis

Background This study evaluated the prognostic impact of D2 lymphadenectomy combined with splenectomy in patients with advanced proximal gastric cancer and lymph node metastasis at the splenic hilum （No. 10 lymph nodes）. Methods The clinical records of 216 patients with advanced proximal gastric cancer and No. 10 lymph node metastasis who underwent D2 curative resection were retrospectively analyzed. Seventy-three patients underwent simultaneous splenectomy （splenectomy group）, while 143 patients did not （spleen-preserving group）. Five-year survival rates, mean numbers of dissected No. 10 lymph nodes and metastatic No. 10 lymph nodes, and operative morbidity and mortality were calculated and compared between the two groups. Potential prognostic factors were evaluated by univariate and multivariate analysis.
Results The 5-year survival rate was 30.0% for the splenectomy group and 19.7% for the spleen-preserving group （χ^2=14.73, P 〈0.05）. The mean numbers of dissected No. 10 lymph nodes and metastatic No. 10 lymph nodes in the splenectomy group were significantly greater than in the spleen-preserving group （P 〈0.05）. Multivariate analysis revealed that the depth of invasion, splenectomy, and type of gastrectomy were independent prognostic factors. The survival rate for T3 patients with and without splenectomy was 38.7% and 18.9%, respectively （χ^2 =15.03, P 〈0.05）. For patients undergoing total gastrectomy, survival rates were 33.4% and 20.7%, respectively （χ^2 =13.63, P〈0.05）. Operative morbidity and mortality in splenectomy group was 24.7% and 4.1%, respectively, and in the spleen-preserving group was 17.5% and 3.5%, respectively. The differences were not statistically significant （P 〉0.05）. Conclusions Splenectomy is beneficial for No. 10 lymph node dissection in patients with advanced proximal gastric cancer. To improve patient prognosis, total gastrectomy with splenectomy is recommended for patients with T3 proximal gastric cancer who have No. 10 lymph node metastasis.

Proximal gastric cancer: lymph node metastatic patterns according to different T stages dictate surgical approach

Background As a common form of gastric cancer migration,lymph node metastasis largely affects the surgical treatment and prognosis of gastric cancer.Surgery is the fundamental curative option for gastric cancer that varies depending on different stages.The study aimed to compare the clinicopathological characteristics and lymph node metastatic patterns in patients of proximal gastric cancer with different T stages and investigate a reasonable radical gastrectomy approach in terms of the range of lymphadenectomy for proximal gastric cancer.Methods In our retrospective study,the data of 328 patients of proximal gastric cancer with different T stages were analyzed.By comparing the differences of lymph node metastatic rate and ratio,we investigated the clinicopathological characteristics and metastatic patterns of lymph nodes.Also,we were especially interested in the differences in survival rates between patients with and without No.5 and 6 group metastasis with the same TNM stage.Results The overall lymph node metastatic rate and ratio of advanced proximal gastric cancer were 73.4％ and 23.3％,respectively.The tumors of different T stages were statistically significant in size and differentiation degree （P ＜0.05）,multivariate analysis showed that the depth of tumor invasion was an independent risk factor for lymph node metastasis in proximal gastric cancer （RR,12.025; 95％ CI,2.326 to 62.157; P=0.003）.The overall survival rate of patients with No.5,6 group lymph node metastasis and those without was significantly different,but the differences in survival rates between patients with and without No.5 and 6 group metastasis with the same TNM stage were not statistically significant.Conclusions Different T stages in proximal gastric cancer showed different patterns and characteristics of lymph node metastasis.D2 lymphadenectomy in patients with early gastric cancer had little survival benefit because metastasis to level 2 nodes was rare.Therefore the range of the lymph node dissection in radical gastrectomy

Lymph node metastases of adenocarcinoma of the esophagus and esophagogastric junction

Background Esophageal adenocarcinoma is becoming an increasingly important problem. It has been the most rapidly increasing malignancy in western countries in the last decades, and its prognosis is poor. The aim of this study was to evaluate the relationship between tumor invasion depth and lymph node metastasis for adenocarcinoma of the esophagus and esophagogastric junction, and to analyze the impact of lymph node metastases on survival of the patients.Methods The study group comprised 121 patients with adenocarcinoma of the esophagus or esophagogastric junction, who underwent esophagectomy between January 1985 and December 2003 at either the Royal Adelaide Hospital or the Flinders Medical Center, Australia. Overall, there were 101 males and 20 females, with a mean age at surgery of 62 years (range 36–80). All of them were followed up for 6 months to 13 years (mean, 6.5 years). The relationship between tumor invasion depth and lymph node metastasis, as well as between survival and lymph node metastasis in these patients were analyzed by Chi-square or Fisher’s exact test. A P<0.05 was considered statistically significant.Results The tumors were located entirely within the esophagus in 83 patients, and involved the gastro-esophageal junction in 38. The overall resection rate was 96.7% (117/121). When tumor invasion was within mucosa or submucosa of the esophagus (T(1)), the lymph node metastasis rate was 22.2% (10/45), the mean number of metastatic lymph nodes was 0.3, and the proportion of more than 4 lymph nodess metastases was 0% (0/45). When tumor invaded the adjacent structures of the esophagus (T(4)), the lymph node metastasis rate was 85.7% (6/7); the mean number of metastatic lymph nodes was 5.1, and the proportion of more than 4 lymph nodes metastases was 71.4% (5/7). There was a significant difference between T(1) and T(4) (P<0.01). The 5-year survival rate for patients without lymph node metastasis was 52.9%, for those with 1-4 nodes involved was 11.5%, and for patients with more than 4 positive nodes was 0.0% (P<0.01). Conclusions There is a close association between tumor invasion depth and lymph node metastasis for adenocarcinoma of the esophagus and esophagogastric junction. Both the number and rate of lymph node metastasis are significantly correlated to the depth of tumor invasion. Moreover, when the tumor invades deeper into the esophageal wall, the percentage of patients with more than 4 involved nodes increases. Both the lymph node status and the number of metastatic nodes are important prognostic factors for the disease.     

Relations of proliferative activities of gastric carcinoma cells to lymphatic involvement, venous invasion and prognosis

Background This study was to evaluate bivariate bromodeoxyuridine(BrdUrd)/DNA flow cytometric analysis in detection of gastric carcinoma and to study the relations of cellular BrdUrd labeling indices (LI), G2/M-phase fraction(G2/MPF) and DNA ploidy pattern to lymphatic involvement, venous invasion and prognosis.Methods Fresh tumor samples from 60 patients with gastric carcinoma were analyzed by bivariate BrdUrd/DNA flow cytometry. The results were correlated with lymphatic vessel invasion, lymphatic node metastasis, the number of matastatic lymphatic nodes, and venous invasion. Propidium iodide (PI) was used as a fluorescent probe for total cellular DNA, and a monoclonal antibody against BrdUrd was used as a probe for BrdUrd incorporated into DNA. Fluorescent-labeled goat anti-mouse antibody was used as a second antibody. S-phase fractions were measured by in vitro BrdUrd labeling, and DNA ploidy and G2/MPF were also measured. Comparison of survival was performed with the log-rank test, the Chi-square test for qualitative data, and Student’s t test for quantu data. Results BrdUrd LI and G2/MPF values were significantly higher in tumors with lymphatic vessel invasion than in those without invasion respectively (P<0.01); the patients who had tumors with lymphatic vessel invasion showed a significantly poor prognosis (P<0.01). Both BrdUrd LI and G2/MPF values were significantly higher in tumors with lymphatic node metastasis than in those without metastasis (P<0.01). A statistical significant difference was noted in the 5-year survival rates between the patients with lymph node metastasis and those without metastasis. Compared with diploid carcinoma, the incidence of lymph node metastasis was significantly higher in aneuploid carcinoma (P<0.05), and the patients with aneuploid carcinoma showed a significantly poor prognosis (P<0.05). BrdUrd LI was significantly higher in patients with more than 5 metastatic lymph nodes than those with 1-4 metastatic lymph nodes (P<0.05) and those without metastasis (P<0.01). G2/MPF values in those patients either with more than 5 metastatic lymph nodes or 1-4 metastatic lymph nodes were higher than those without metastasis (P<0.01 and P<0.05). A statistical significance was seen in the 5-year survival rates among the patients with no metastatic lymph node, 1-4 metastatic nodes and more than 5 metastatic nodes (P<0.01). G2/MPF values were significantly higher in patients with venous invasion than in those without invasion (P<0.01).Conclusions Positive correlations exist between cellular BrdUrd LI, G2/MPF with lymphatic involvement and prognosis, and DNA aneuploid with lymphatic involvement and prognosis. The same was true between G2/MPF value and venous invasion in gastric carcinoma.
