[Perivesical abscess secondary to ruptured appendicitis : a case report].

A 38 year-old man was referred to our hospital for high fever and lower abdominal pain. The laboratory data showed his inflammatory state with a few puss cells in the urine analysis. Computed tomography (CT) scan and magnetic resonance imaging (MRI) scan demonstrated perivesical abscess and the cystoscopy on the day just before the operation revealed no abnormal findings in the bladder mucosa.

Impact of lymphovascular invasion in patients with stage I gastric cancer.

Background: Patients with stage I gastric cancer often suffer from tumor recurrence despite a generally favorable operative outcome. It is therefore important to determine the prognostic factors in order to improve such outcomes.

Methods: Between April 1985 and March 2000, a total of 1,880 patients with histologically proven stage I gastric cancer were included in this study.

[Efficacy of low-dose CDDP and CPT-11 for patients with intestinal type of gastric adenocarcinoma].

Background: Preclinical studies have shown that irinotecan (CPT-11) and cisplatin (CDDP) can act synergistically. Several chemotherapy regimens combining CPT-11 and CDDP for advanced gastric cancer have been reported to demonstrate high response rates and high incidence of severe toxicity.

Purpose: We conducted a combination chemotherapy regimen of low-dose CDDP and CPT-11 to prolong the time to progression with less toxicity.

Phase I study of biweekly docetaxel and S-1 combination chemotherapy for advanced gastric cancer.

Background: Docetaxel and S-1 are novel antitumour chemotherapeutic agents with distinct toxicities. Here a phase I study of combined docetaxel and S-1 therapy for advanced gastric cancer is reported.

Patients And Methods: The study group comprised 21 patients who received at least two courses of treatment.

The influence of stage migration on the comparison of surgical outcomes between D2 gastrectomy and D3 gastrectomy (para-aortic lymph node dissection): a multi-institutional retrospective study.

Background: The aim of this study was to determine the influence of stage migration on the outcomes of D2 gastrectomy compared with D3 gastrectomy in advanced gastric cancer.

Methods: A series of 580 advanced gastric cancer patients (430 D2 gastrectomy and 150 D3 gastrectomy) were registered. The incidence of stage migration and the surgical results of D2 and D3 gastrectomy were compared.

Clinical significance of the metastatic lymph-node ratio in early gastric cancer.

The metastatic lymph-node ratio has important prognostic value in gastric cancer; this study focused on its significance in early gastric cancer. In total, 1,472 patients with early gastric cancer underwent curative gastrectomy between 1992 and 2001. Of these, 166 (11.

Lymph node status in patients with submucosal gastric cancer.

Background: The aim of this study was to clarify the lymph node status in patients with submucosal gastric cancer.

Methods: Between April 1994 and December 1999, 615 patients with histologically proven submucosal gastric cancer who underwent curative resection were included in this study. The results of the surgery and predictive factors for lymph node metastasis were evaluated by univariate and multivariate analyses.

Clinicopathological features of gastric carcinoma in younger and middle-aged patients: a comparative study.

Gastric carcinoma is relatively rare in patients under the age of 40. This study was undertaken to clarify the clinicopathological characteristics and surgical outcomes of gastric carcinoma in younger patients compared with those of middle-aged patients. The surgical results from 131 younger patients (aged < or = 40 years) and 918 middle-aged patients (aged 55-65 years) were compared retrospectively.

Clinicopathological properties of poorly-differentiated adenocarcinoma of the stomach: comparison of solid- and non-solid-types.

Background: The purpose of this study was to clarify the clinicopathological and biological properties of the poorly-differentiated types of gastric carcinoma (solid-type and non-solid-type).

Patients And Methods: A total of 1,558 patients with primary gastric adenocarcinomas were enrolled in this study. The surgical results were compared.

Comparison of surgical results of D2 versus D3 gastrectomy (para-aortic lymph node dissection) for advanced gastric carcinoma: a multi-institutional study.

Background: Curative gastrectomy is a promising approach for the treatment of gastric cancer; however, the optimal extent of lymph node dissection for advanced cancer remains controversial. The aim of this multi-institutional study was to evaluate the feasibility of D3 gastrectomy (para-aortic lymph node dissection) for advanced gastric cancer. The surgical results of D2 and D3 gastrectomy (para-aortic lymph node dissection) were retrospectively compared.

Significance of long-term follow-up of early gastric cancer.

Background: Therapeutic outcomes for most patients with early gastric cancer are favorable. However, mortality among these patients remains a concern. Improvements in therapeutic outcomes are being sought by studying the timing and causes of death.

Surgical outcomes in patients with T4 gastric carcinoma.

Background: There is controversy about the best therapeutic surgical approach for treatment of patients with T4 gastric cancer.

Study Design: We used univariate and multivariate analyses to review the surgical outcomes and prognostic factors of 117 patients who underwent surgery for T4 gastric carcinoma.

Results: Curative resection was performed in 38 (32.

[Effect of hepatic arterial infusion chemotherapy for liver metastasis from gastric cancer].

We performed hepatic arterial infusion (HAI) chemotherapy for 4 patients with advanced gastric cancer who had undergone curative resection except for liver metastasis. The main antineoplastic drugs were 5-fluorouracil (5-FU), mitomycin C (MMC) and cisplatin (CDDP). A catheter was inserted into the hepatic artery by interventional radiological techniques in 3 patients and operatively in 1 patient.
