AIM To evaluate the impact of obesity on the posto-perative outcome after hepatic resection in patients with hepatocellular carcinoma (HCC). METHODS Data from 328 consecutive patients with primary HCC and 60 patients with recurrent HCC were studied. We compared the surgical outcomes between the non-obese group (body mass index: BMI < 25 kg/m(2)) and the(More)
BACKGROUND Hepatocellular carcinoma (HCC) ≤ 2 cm in diameter is considered to have a low potential for malignancy. METHODS A retrospective review was undertaken of 149 patients with primary solitary HCC ≤ 2 cm who underwent initial hepatic resection between 1994 and 2010. The independent predictors of the microinvasion (MI) such as portal venous, hepatic(More)
Gastrointestinal stromal tumors (GISTs) commonly harbor oncogenic mutations of the c-kit receptor gene, which are targets for imatinib mesylate. However, imatinib resistance is an increasing clinical problem. We herein present such a case with a recurrent GIST, in association with the development of a secondary mutation in the c-kit gene. A 67-year-old man,(More)
Elevated soluble interleukin-2 receptor (sIL-2R) in sera is observed in patients with malignant lymphoma (ML). Therefore, sIL-2R is commonly used as a diagnostic and prognostic marker for ML, but the mechanisms responsible for the increase in sIL-2R levels in patients with B-cell lymphomas have not yet been elucidated. We first hypothesized that lymphoma(More)
BACKGROUND/AIMS The aim of the present study was to re-evaluate CY(+) with gastric carcinoma in Japanese patients to identify the characteristics that might distinguish patients with a poor prognosis from those with an intermediate prognosis among CY(+) patients. METHODOLOGY CY(+) was found in 56 of 566 patients (9.9%) who had undergone surgery for(More)
This report describes the successful treatment of a case of true gastric cancer presenting as protein-losing gastroenteropathy. A 58-year-old Japanese male presented gastric carcinoma. His serum albumin and total protein levels were 1.8 and 4.2 g/dl, respectively. He was diagnosed with gastric cancer with protein-losing gastroenteropathy based on(More)
BACKGROUND/AIMS Surgically resected hepatocellular carcinomas (HCC) in patients with non-alcoholic steatohepatitis (NASH) have rarely been described and the clinicopathological characteristics of HCC and non-cancerous liver tissue are still obscure. METHODOLOGY From 1997 to 2004, 242 patients with HCC underwent hepatic resection at the Hiroshima Red Cross(More)
A 67-year-old woman was admitted to our hospital because of breathlessness. Systemic amyloidosis had been diagnosed 5 years previously. Her chest X-ray film showed multiple nodules in both lung fields. Chest computed tomography (CT) revealed some of the nodules had calcifications. Bronchoscopy demonstrated amyloid deposits in the bronchial walls. The serum(More)
A 61-year-old man was admitted to our hospital with cough, breathlessness, anorexia and chest pain. Chest radiograph showed right pleural effusion and also a chest CT scan showed right pleural effusion with thickening of the right visceral pleura, pericardial effusion and a liver tumor. The pleural effusion was slightly bloody and exudative. The adenosine(More)
A 35-year-old woman with past history of pneumonia in the right lung field 5 years before was admitted to our hospital because of fever and cough. Chest radiographs showed a pulmonary tumor with atelectasis of the right lower lung. Chest CT also revealed a round clear-edged tumor at the right S6 with atelectasis of the right lower lung lobe. Bronchoscopic(More)
