【Abstract】ObjectiveTo discuss how to improve the current status on clinical therapy for advanced gastric carcinoma. MethodsRelated literatures searched on Medline were collected and reviewed. ResultsThe 5th edition of UICC/AJCC TNM staging system of gastric carcinoma is useful to evaluate the prognosis of patients with advanced gastric carcinoma followed by extended lymphadenectomy. There are many factors influencing their prognosis including disease stage, extent of lymphadenectomy, assistant therapy and so on. ConclusionIt is significant for patients with advanced gastric carcinoma to undergo individualized extended lymphadenectomy and comprehensive therapy to improve their prognosis after radical gastrectomy
ObjectiveTo review the research advances about myeloid derived suppressor cells(MDSC)and pancreatic cancer, and explore the future research trends. MethodRelated literatures in recent 5 years from abroad databases(PubMed, Web of Science, and EMBASE)and domestic databases(CNKI, WANFANG, and WEIPU)were collected and reviewed. ResultsThe MDSC was the core of tumor immune regulation network in pancreatic cancer microenvironment, it formed a complicated feedback with the pancreatic cancer and the stellate cells. MDSC could promote the cancerogensis and progression of pancreatic cancer, and the accumulation of MDSC in peripheral blood of pancreatic cancer patient could predict the poor prognosis. However up to now, the literatures about the relation between MDSC and the chemotherapy and metastasis of pancreatic cancer were limited. ConclusionsThe comprehensive therapy by targeting MDSC of pancreatic cancer is promising. However, many issues need to be further investigated.
