A Prospective Multicenter Phase II Study on the Feasibility and Efficacy of S-1 and Oxaliplatin Neoadjuvant Chemotherapy for Locally Advanced Rectal Cancer.

Background: Neoadjuvant chemoradiotherapy and total mesorectal excision compose the standard of care for rectal cancer in multiple guidelines. However, neoadjuvant chemoradiotherapy has not exhibited clear survival benefits but rather has led to an increase in adverse events. Conversely, neoadjuvant chemotherapy is expected to prevent adverse events caused by radiation, yet this treatment is still controversial.

[Ischemic Colitis after Closure of Temporary Ileostomy for Low Anterior Resection of Rectal Cancer in a Dialysis Patient-A Case Report].

Dialysis patients are at increased risk of ischemic colitis and are likely to develop irreversible ischemic colitis. We report a rare case of ischemic colitis after the closure of a temporary ileostomy for low anterior resection(LAR)of rectal cancer in a dialysis patient. A 77-year-old man undergoing maintenance dialysis was diagnosed as having colorectal cancer with a type 2 tumor at the anastomosis site of high anterior resection performed for sigmoid colon cancer 14 years ago.

[A Case of Strangulation Ileus with Hemorrhagic Shock Caused by an Internal Hernia of the Small Intestine].

Patient: An 81-year-old man. Past medical history: distal gastrectomy and Roux-en-Y reconstruction.

Chief Complaint: epigastric pain, nausea, and hematemesis.

[A case of complete remission(CR)persisting from UFT-E in an old patient with liver metastasis of gastric cancer].

A 82-year-old woman with gastric cancer underwent distal gastrectomy with level 2 lymph node dissection(M, Less, 2.2 x 2.0 cm, type 1, fH0, fP0, fM0, fT2, fN2(+), por 1, med, INF beta, ly2, v2, fPM(-), fDM(-), fStage IIIa).

[A case of perforated gastric cancer in which complete response was confirmed with resection following TS-1/CDDP combined chemotherapy after omentopexy].

The present patient was a 50-year-old male with sudden upper abdominal pain. The patient exhibited pallor, and physical examination revealed a rigid abdomen. Abdominal x-ray revealed free air, and emergency laparotomy was performed to confirm upper gastrointestinal tract perforation.
