A woman in her 70s was diagnosed with a protruding mucosa-associated lymphoid tissue (MALT) lymphoma during a secondary health examination. After eradication of Helicobacter pylori, a biopsy revealed gastric follicular lymphoma (FL) and the lesion was still protruding one year later.

Stricture of the celiac artery caused by the median arcuate ligament induces abdominal ischemic symptoms and aneurysm near the pancreatic head. However, the need to treat asymptomatic patients is unclear. We safely performed surgical decompression of a stricture of the celiac artery by MAL in an asymptomatic patient at the same time as gastrectomy for gastric cancer. After surgery, the stricture of the celiac artery had disappeared as demonstrated by CT scan and 3-D CT angiography.

Our aim was to evaluate postoperative adjuvant chemotherapy using S-1 plus cisplatin(S-1/CDDP)for type 4 gastric cancer.We investigated 18 patients who had undergone curative operations for type 4 gastric cancer. They were classified into two groups of patients, one using S-1/CDDP(group A: 9)and one using S-1 alone(group B: 9), after surgery between 2000 and 2010. Median survival time(MST)and survival rates were reported retrospectively. Patients as- signed to group A were treated with the following regimen: S-1, 80-120mg/day(body surface area 1. 25m2: 80mg/day, 1. 25-1. 5m2: 100mg/day, 1. 5m2: 120mg), was administered for 21 consecutive days followed by a 14-day rest period, and CDDP, 60mg/m2, was administered on day 8 for 5 courses. After this course, S-1 80mg/m2 was given for 18 months. S- 1(80-120mg/day, body surface area 1. 25m2: 80mg/day, 1. 25-1. 5m2: 100mg/day, 1. 5m2: 120mg)was administered for 28 days followed by 14-day rest as one course.MST differed significantly between group A and group B (MST; group A: 1, 603 vs group B: 955 days). The overall survival rate at 5 years was 64. 8% in group A and 13% in group B, and the overall survival rate in group A was statistically better than that in group B(p=0. 02).Postoperative adjuvant chemotherapy using S-1/CDDP for resected type 4 gastric cancer contributes to prolonged life, compared with using S-1 in overall survival.

A 75-year-old man with type 4 advanced gastric cancer was referred to our hospital. We diagnosed the tumor as cStage III B(cT4a, cN2, cM0)gastric cancer. We selected neoadjuvant S-1 combined with CDDP therapy for him. After 2 courses of chemotherapy, the extension of the gastric wall improved. After an additional 2 courses of chemotherapy, the primary tumor revealed a partial response(PR), judged from a barium meal study and upper GI endoscopic findings, and a total gastrectomy with lymph node dissection was performed. The pathological specimens showed no cancer cells in the gastric wall and lymph nodes, so the histological effect was judged as Grade 3.

A 50-year-old man with advanced gastric cancer and a tumor embolus in the portal vein was referred to our hospital. We diagnosed the tumor as cStage III B (cT3, cN2, cH0, P0, M0) gastric cancer, and selected neoadjuvant S-1 (80 mg/m2) and CDDP (60 mg/m2) therapy for him. After 2 courses of chemotherapy, the embolus in the portal vein disappeared. After additional chemotherapy, the primary tumor and regional lymph node revealed a partial response (PR), and judging from the results from the barium meal study, upper GI endoscopic findings and CT scan, a total gastrectomy with lymph node dissection was performed.

A 54-year-old man suffering from Borrmann type 4 advanced gastric cancer with pancreatic invasion and paraaortic lymph node metastases underwent a total gastrectomy, which was a radical C operation. From postoperative month 4, he visited our hospital with multiple liver metastases and increased lymph node metastases. After chemotherapy with CDDP and 5-FU, CDDP and UFT was administered on an outpatient basis. The effect of this therapy was PD, therefore, docetaxel and 5'-DFUR combination chemotherapy was performed as second line therapy. After 2 courses of this therapy, the size of liver and lymph node metastases was reduced and the effect of this therapy was PR. The patient has undergone 4 courses of this therapy and is maintaining a clinical PR. It is conceivable that docetaxel and 5'-DFUR combination chemotherapy is useful for patients with advanced and recurrent gastric cancer, even if they had been treated with 5-FU administration as first line therapy.
