Patients and Methods: Clinicopathological characteristics and prognostic outcomes of 310 patients who had lymph node-negative advanced gastric adenocarcinoma and received curative resection between 2002 and 2006 were retrospectively evaluated. Results: Among the 300 patients, 15 (5.0%) had locoregional recurrence, 5 (1.7%) had lymph node recurrence, 27 (9.0%) had peritoneal seeding recurrence, and 21 (7.0%) had hematogenous metastasis. Using multivariate analysis, we found that the maximum tumor diameter (P=0.014), histological type (P=0.001) and Borrmann type (P=0.033) were independent factors predicting the locoregional recurrence. Lymph node recurrence was significantly affected by lymph node dissection (P=0.029) and lymphovascular invasion (P=0.004). Clinicopathological factors predicting the peritoneal seeding recurrence were the depth of invasion (P=0.001) and Borrmann type (P=0.002). In addition, lymphovascular invasion (P=0.013) and histological type (P=0.001) were significantly associated with hematogenous metastasis. Conclusion: Node-negative advanced gastric cancer has a high amount of peritoneal seeding and hematogenous metastasis.展开更多

However, a much deeper understanding of oncogenic proteins is needed for the benefit to cancer patients. The lipid raft marker proteins, flotillin-1 and flotillin-2, were first found in goldfish retinal ganglion cells during axon regeneration. They have since been found in a variety of cells, mainly on the inner surface of cell membranes, and not only act as a skeleton to provide a platform for protein-protein interactions, but also are involved in signal transduction, nerve regeneration, endocytosis, and lymphocyte activation. Previous studies have shown that flotillins are closely associated with tumor development, invasion, and metastasis. In this article, we review the functions of flotillins in relevant cell processes, their underlying mechanisms of action in a variety of tumors, and their potential applications to tumor molecular diagnosis and targeted therapy.展开更多
