Early EN with a large amount of omega-3 PUFAs in reduced platelet aggregation, coagulation activity, and cytokine production. All these effects would be expected to be beneficial in patients following esophageal cancer surgery. The clinical significance of the changes in eicosanoid production remains to be established.

Proximal gastrectomy through a transhiatal approach may be the optimal surgical strategy for esophagogastric carcinoma. Mediastinal lymph node dissection through a thoracic approach seems unnecessary, particularly when the tumor center is located below the esophagogastric junction. To confirm the necessity of para-aortic nodal dissection, further studies are required.

The prognosis of patients with RGC can be improved by aggressively performing curative resection without causing complications.

We achieved 100 % SN detection. Our results suggested that SN mapping is feasible for AEG and highly sensitive and accurate in diagnosing lymph node metastasis. SN mapping may clarify the necessity of mediastinal lymph node dissection and individualize minimally invasive surgery.

A 68-year-old woman presented with severe bowel obstruction and was subsequently diagnosed with stage IV gastric cancer with peritoneal dissemination. She was immediately stabilized in the hospital with the placement of a nasointestinal tube. Abdominal computed tomography showed multiple intraperitoneal nodules consistent with peritoneal dissemination of the gastric cancer. The patient's inability to tolerate oral intake was a contraindication to using S-1 chemotherapy, currently one of the most effective medications used for gastric cancer in Japan. Therefore, she was initially treated with octreotide acetate (OA). Her bowel obstruction was sufficiently attenuated on the seventh day after the initiation of treatment with OA to permit the initiation of oral S-1, along with low-dose cisplatin (CDDP) and radiation. S-1 was orally administered at a dose of 100 mg/day per body (80 mg/m(2) per day) on days 1-28, and CDDP was infused at a dose of 7.8 mg/day per body (6 mg/m(2) per day) on days 1-5, 8-12, and 15-19. Radiation therapy (2 Gy/day for 5 days/week) was performed with the chemotherapy. Despite no change being shown on her imaging findings with the chemotherapy, the patient's bowel obstruction resolved and she was able to tolerate both liquids and solid food orally. She was discharged 2 months after admission. Seven months after beginning the chemotherapy, she was still doing well on outpatient chemotherapy with S-1 and CDDP, and had no decline in her quality of life or progression of her disease.
