age alone is not sufficient reason to withhold curative or palliative treatment from elderly gastric cancer patients. Patient selection and risk-adapted surgery in elderly patients can obtain an acceptable therapeutic result comparable to that for younger patients. Perioperative chemotherapy or postoperative chemotherapy should be added in cases of locally advanced gastric cancer. Palliative systemic chemotherapy seems to prolong survival in recurrent and metastatic disease. Now, an aging society is coming in Japan, which has one of the oldest populations in the world. This article concerning people aged 85 years or older is presented at Baf-A1 manufacturer a timely point. In this issue of the International Journal of Clinical Oncology, Dr. Endo report topics of

the prognosis of gastric cancer patients aged 85 years and older, which reveal that females, patients aged 85–89 years, and patients with advanced cancer had better survival with surgery [1]. On the other hand, for males, patients aged ≥90 years, or patients with early cancer, best supportive care VX-680 (BSC) might be an optimal strategy. Conflict of interest The author declares that he has no conflict of interest. Reference 1.

“There are several morphological pathways by which lymph node metastasis can arise: invasion into a deeper layer; detachment of tumor cells from the primary tumor; infiltration into intramural lymphatics; flow to extramural lymphatics; arrival to afferent lymphatics of a marginal sinus; movement to the lymph node cortex; and implantation of tumor cells into the node and formation of metastasis. Some cancer cells move from an efferent

lymphatic vessel to the next lymph node. In terms of the first step toward lymph node metastasis, a small number of cancer cells is thought to be related to the formation of metastasis. check details recent research into biological aspects has elucidated various tumor characteristics. What kinds of tumor cells have metastatic potential? Many medroxyprogesterone molecules in the pathways toward lymphatic metastasis are thought to be related. Once tumor cells invade the lymphatics, can all cells implant into lymph nodes? Numerous immune cells are originally present in the lymph nodes, and such cells fight and defend against the invasion of bacteria, viruses, tumor cells, and so on. Thus, it is speculated that only certain special cancer cells can implant and grow to form an overt metastasis. What are these special cancer cells? The recent concept of epithelial-mesenchymal transition and the stem cell theory seems to offer an important key to solving the properties of tumor cells.
