[A Large Gastric Gastrointestinal Stromal Tumor Successfully Treated with Neoadjuvant Imatinib Followed by Surgery-A Case Report].

Neoadjuvant imatinib may prevent tumor rupture and the need for extended surgery by reducing the tumor size by approximately 35%, especially for large gastric gastrointestinal stromal tumors(GISTs), as shown in a previous phase Ⅱ study (Kurokawa et al. BJC 2017); however, the use ofneoadjuvant imatinib is not prevalent in clinical practice. Herein, we report a large gastric GIST that was successfully treated with neoadjuvant imatinib.

Case of complete mesh migration into the stomach after mesh hiatoplasty for a hiatal hernia.

Mesh migration is a rare complication of surgery for a hiatal hernia. Here, we present the case of a 72-year-old who complained of dysphasia and bodyweight loss. Upper gastrointestinal endoscopy revealed incarcerated mesh in the lumen of the esophagogastric junction.

[Outcomes of Staging Laparoscopy in Eight Patients with Positive Peritoneal Washing Cytology after S-1 Administration].

Aim: The aim of this study was to clarify the clinical outcomes of staging laparoscopy(SL)for patients with positive peritonealwashing cytology(CY1P0)after S-1 administration.

Patients And Methods: Since 2007, eight CY1P0 patients who underwent SL after S-1 administration were enrolled. S-1 was administered according to the ACTS-GC and SL was performed after 8 courses of S-1 treatment.

[Administration of S-1 Monotherapy as Adjuvant Chemotherapy in a Patient with Advanced Gastric Cancer with HIV Infection].

A 64-year-old man with advanced gastric cancer presented with chief complaints of chest pain. His preoperative blood examination revealed positive results for serum HIV-antibody. His HIV-RNA level was 1.

A Case of Laparoscopic Resection for Carcinoma of the Gastric Remnant following Proximal Gastrectomy Reconstructed with Jejunal Interposition.

A 72-year-old Japanese man had a history of proximal gastrectomy for early gastric cancer located in the upper third of the stomach in 2007. Our usual treatment strategy for early gastric cancer in the upper third of the stomach in 2007 was open proximal gastrectomy reconstructing by jejunal interposition with a 10 cm single loop. Upper gastrointestinal fiberscopy for annual follow-up revealed a type 0-IIc-shaped tumor with ulcer scar, 4.

Totally laparoscopic gastrectomy for early gastric cancer accompanied by huge hiatal hernia: A case report.

We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made.

[Multidisciplinary Treatment for a Patient with Primary Malignant Melanoma Arising from the Stomach].

A 61-year-old woman was referred to our hospital with the complaint of severe dysphagia. Upper gastrointestinal endoscopy revealed an elevated tumor with an irregular surface located in the upper third of the stomach, and malignant melanoma was confirmed by biopsy specimens. Abdominal CT scan findings revealed that the tumor was invading the lateral segment of the liver and crus of the diaphragm.

[Effectiveness of chemoradiotherapy for a patient with local recurrence of advanced gastric cancer followed by curable gastrectomy].

We report here the effectiveness of chemoradiotherapy for a patient with local recurrence followed by curable gastrectomy. A 57-year-old man presented with a history of total gastrectomy with distal pancreatectomy and splenectomy, D2 lymphadenectomy, and Roux-en-Y reconstruction for advanced gastric cancer arising from the cardia. Esophageal intramural metastasis and lymph node metastasis around the right recurrent nerve were detected by chest-abdominal computed tomography and gastrointestinal endoscopy 27 months after the initial gastrectomy.

[A case of early gastric cancer with multiple synchronous bone metastases treated complete response with S-1+CDDP].

We report a case of complete response (CR) following induction chemotherapy using S-1 for a patient with early gastric cancer accompanied by multiple synchronous bone metastases. An asymptomatic 70-year-old woman was diagnosed with early gastric cancer by upper gastrointestinal endoscopy during a periodic medical examination. An abdomino-pelvic computed tomography (CT) scan revealed no primary tumor in the stomach and the absence of lymph node or liver metastases.

[How does we treat liver metastases from colorectal cancer by cure-intent surgery ?].

Surgery is the most optimal and curative intent strategy for liver recurrence from colorectal cancer. There are scoring systems and grade classification for liver resection. If we carry out preoperative imaging of liver metastases strictly following to liver resection, we can expect to get a cure state satisfactory.

[A clinical case of lymph node recurrence after the resection of esophagogastric junction cancer treated by chemoradiation therapy].

A 52-year-old man who was diagnosed with esophagogastric junction cancer underwent left thoracolaparotomy and total gastrectomy. At 3 years and 11 months after the surgery, his carcinoembryonic antigen value was elevated, and cervical and right paraesophageal lymph node enlargement was detected by chest computed tomography(CT). Although lymph node dissection was performed, the presence of microscopic cancer-positive surgical stumps was confirmed.

[Therapeutic strategy for gastric cancer with positive peritoneal lavage cytology without peritoneal dissemination].

We analyzed the prognosis of patients with positive lavage cytology, excluding other unresectable factors.From 2002 to 2008, 76 advanced gastric cancer patients positive for malignant cells(CY1)were investigated for our study.There were 60 patients undergoing gastric cancer surgery.

[Is it necessary to carry out hepatic resection and pulmonary resection to obtain a cure for liver and lung metastases from colorectal cancer ?].

If hepatic or pulmonary metastases from colorectal cancer are resectable, we perform the operation, and the 5-year survival rate is 40-50%. Median survival time is over 20 months recently for systemic chemotherapy. However, surgical treatment is the only way to obtain a cure.

[Surgery for colorectal cancer in elderly patients].

The number of surgeries for colorectal cancer in elderly patients is increasing in correspondence to Japan's aging society. It is important to evaluate the patient's condition in order to carry out operations safely. The Onodera index (Onodera index in order (PNI: prognostic nutritional index)=serum alb value × 10+the lymphocyte counts of peripheral blood) is a simple and useful tool for choosing the method of operation.
