Recent Strategies for Treating Stage IV Gastric Cancer: Roles of Palliative Gastrectomy, Chemotherapy, and Radiotherapy.

Recently, many strategies have been reported for the effective treatment of gastric cancer. However, the strategy for treating stage IV gastric cancer remains controversial. Conducting a prospective phase III study in stage IV cancer patients is difficult because of heterogeneous performance status, age, and degree of cancer metastasis or extension.

Small bowel obstruction caused by endometriosis in a postmenopausal woman.

We report a rare case of small bowel obstruction (SBO) caused by endometriosis in a postmenopausal woman. A 54-year-old postmenopausal woman presented with severe abdominal pain and vomiting. Before menopause, she sometimes had abdominal pain associated with menses.

Pathological complete response and long-term survival in a very elderly patient after neoadjuvant chemotherapy for locally advanced, unresectable gastric cancer.

We address the pathological complete response and long-term survival of elderly patients after neoadjuvant chemotherapy in locally advanced, unresectable gastric cancer. An 83-year-old man was hospitalized for upper abdominal pain. Gastrointestinal endoscopy showed a large tumor spanning from the gastric angle to the antrum, and extending to the duodenum.

Profile of microRNAs associated with aging in rat liver.

Recent studies suggest that small non‑coding microRNAs (miRNAs or miRs) play an important role in the regulation of genes involved in various cellular and developmental processes. However, the expression of miRNAs during the aging process remains largely unknown. The aim of the present study was to analyze miRNA expression profiles in rat livers during the aging process.

Current innovations in endoscopic therapy for the management of colorectal cancer: from endoscopic submucosal dissection to endoscopic full-thickness resection.

Endoscopic submucosal dissection (ESD) is accepted as a minimally invasive treatment for colorectal cancer. However, due to technical difficulties and an increased rate of complications, ESD is not widely used in the colorectum. In some cases, endoscopic treatment alone is insufficient for disease control, and laparoscopic surgery is required.
