[A case of an elderly patient with recurrent GIST, which was effectively treated with low-dose imatinib mesylate].

The recommended dose of imatinib for recurrent gastrointestinal stromal tumors (GIST) is 400mg/day. However, adverse effects limit the use of the standard dose in elderly patients. We report a case of an elderly patient with recurrent GIST, where long-term control of the disease was achieved with low-dose imatinib therapy.

[A case report of goblet cell carcinoid tumor of the appendix].

Goblet cell carcinoid (GCC) tumor of the appendix is rare, and the prognosis is considered poor compared to classical carcinoid tumor. We present a case of a 60-year old woman who underwent appendectomy for acute appendicitis. Histopathological studies revealed a GCC tumor with submucosal invasion.

[A case report of long-term survival in the patient with anorectal malignant melanoma].

Malignant melanoma of the anorectal region is rare, and the prognosis is considered to be poor. We present a case of long-term survival in a 56-year-old patient with primary malignant melanoma in the anorectal area, who complained of anal bleeding. Barium enema showed an elevated lesion in the anorectal region.

[Thymic basaloid carcinoma].

This is a case of a 72-year-old male whose chest computed tomography (CT) revealed a 2.0 x 1.6 cm anterior mediastinal solid tumor during follow-up of an abnormal shadow of the lung.

[Third-line CPT-11 chemotherapy for gastric cancer cases of non-curative gastrectomy or recurrence].

Background: There have been few case reports of 3rd-line chemotherapy for gastric cancer. So we reported the results of CPT-11 therapy as the 3rd-line chemotherapy for gastric cancer.

Patients And Methods: 549 cases underwent gastrectomy from Jan.

A sodium hyaluronate carboxymethylcellulose bioresorbable membrane prevents postoperative small-bowel adhesive obstruction after distal gastrectomy.

Purpose: It is predictable that since distal gastrectomy (DG) with Billroth I anastomosis involves no procedures caudal to transverse colon, the effects of the surgical wound are the main cause of adhesive obstruction. Thus, it is an appropriate operation to test the efficiency of a synthetic absorbable adhesion barrier (Seprafilm).

Methods: The subjects were 282 patients diagnosed with gastric cancer who underwent open DG with Billroth I anastomosis between 2001 and August, 2005.

Distant peritoneal metastasis to a mesh-plug prosthesis in a gastrointestinal cancer patient: report of a case.

A case of distant metastasis to mesh-plug prosthesis in gastrointestinal cancer is presented herein. An 88-year-old man had received mesh-plug repair with high ligation for a recurrence of a right inguinal hernia. Six months later, advanced gastric cancer and advanced transverse colon cancer were detected, and therefore a distal gastrectomy and partial colectomy were performed.

Clinicopathological characteristics of superficial spreading type early gastric cancer.

Background And Objectives: Superficial spreading type early gastric cancer is characterized by its atypical growth pattern and occasionally indistinct tumor margin. Because it is a rare form of early gastric cancer, the clinicopathological details are not apparent. The aim of this study was to clarify the clinicopathological features of the superficial spreading type of early gastric cancer.
