History of the lymph node numbering system in the Japanese Classification of Gastric Carcinoma since 1962
AbstractThe Japanese Classification of Gastric Carcinoma was established by the Japanese Research Society for Gastric Cancer in 1962. The latest 15th edition was published in 2017. One of its main features is that lymph nodes are numbered as stations. The number of groups has increased from 16 to 36 in 55  years. Seven groups (nos. 1, 2, 5, 7, 9, 10, and 15) were retained from the original classification. Nine groups (nos. 3, 4, 6, 8, 11, 12, 13, 14, and 16) were sub-divided into two or more groups. Furthermore, seven groups (nos. 17, 18, 19, 20, 110, 111, and 112) were added in the 6th, 11th, and 1 2th editions. This...

Nutritional impact of active hexose-correlated compound for patients with resectable or borderline-resectable pancreatic cancer treated with neoadjuvant therapy
AbstractActive hexose-correlated compound (AHCC) is a standardized extract from culturedLentinula edodes mycelia, used as a potent biological response modifier in cancer treatment. We evaluated the nutritional effect of AHCC, given during neoadjuvant therapy, to patients with pancreatic ductal adenocarcinoma (PDAC). Thirty patients with resectable or borderline-resectable PDAC received neoadjuvant therapy with gemcitabine plus S-1. We compared, retrospectively, the outcomes of 15 patients who received AHCC combined with neoadjuvant therapy with those of 15 patients who did not receive AHCC combined with neoadjuvant therapy...

However, with advances in GC chemotherapy, multimodal treatment, including perioperative chemotherapy plus conversion surgery, has attracted attention as a new strategy to improve the outcome of patients with stage IV disease. Conversion surgery is defined as surgical treatment aimed at R0 resection after a good response to induction chemotherapy for tumors originally considered unresectable or marginally resectable for technical and/or oncological reasons.

AbstractAdvanced gastric cancers are responsible for overwhelming human suffering and death. Despite the development of combination chemotherapies, the survival rates of patients with gastric cancer remain unsatisfactory. Given the growing evidence of the benefits of immunotherapy as an alternative treatment for other cancers such as advanced melanoma, non-small cell lung cancer, renal cell carcinoma, and refractory Hodgkin ’s lymphoma, researchers have begun to explore its application in the treatment of gastric cancer. Three types of immunotherapy have shown promising effects against gastric cancer: immune checkpoi...
