Insulin resistance predicts rapid virological response in non-diabetic, non-cirrhotic genotype 1 HCV patients treated with peginterferon alpha-2b plus ribavirin.

Background/aims: The rapid decline in hepatitis C virus RNA is crucial for determining the outcome of therapy in patients with genotype 1 chronic hepatitis C. However, the variables influencing the early phase of viral decay are still largely unexplored. We aimed to assess which pre-treatment variable may predict rapid virologic response (RVR) and sustained virologic response (SVR).

Liver transplantation and recurrent hepatocellular carcinoma: predictive value of nodule size in a retrospective and explant study.

Background: Recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT) remains a major cause of post-LT death.

Methods: To assess which preoperative and postoperative variables were related to recurrence of HCC after LT in patients with cirrhosis and HCC, we evaluated 96 patients with cirrhosis (74 with known HCC and 22 with incidental HCC) who survived more than 1 month after LT.

Results: The median waiting list time was 36 days (range 1-370 days), and the median interval from detection to transplant was 180 days (range 14-1460 days).

Blood levels of reduced and oxidized glutathione in malignant and non-malignant human colorectal lesions.

Glutathione blood levels were determined in colorectal cancer patients (n = 10), patients with adenomatous colorectal polyps (n = 8), and healthy subjects (control group; n = 10). Mean GSH level (micrograms/ml) was significantly higher in cancer patients [515.4 +/- 76.

Palliative bipolar electrocoagulation treatment of malignant gastroesophageal strictures.

Seventeen patients with non-resectable circumferential malignant strictures of the esophagus (n = 13) or the gastroesophageal junction (n = 4) were treated with a bipolar electrocoagulation tumor probe (BICAP). None had received prior radiotherapy or chemotherapy. The mean tumor length was 7.

Long-term postoperative results in 54 cases of early gastric cancer: the choice of surgical procedure.

Surgical experience on the management of early gastric carcinoma (EGC) related to a series of 54 subjects was observed from 1974 to 1984. Thirty-four patients were male, 20 were female; median age was 61.84 (range 22-79) years.

Family history of colorectal cancer as a risk factor for benign and malignant tumours of the large bowel. A case-control study.

The relationship between first degree family history of colorectal cancer and the risk of benign or malignant tumours of the large bowel was investigated in a case-control study. Two groups of cases (283 patients with adenomatous polyps and 414 patients with adenocarcinoma of the large bowel) and 2 groups of controls (399 polyp-free subjects and 456 hospitalized patients) were interviewed. Since no difference in the frequency of family history between the 2 control groups was detected, these were lumped together.

Colorectal cancer in patients with family history.

The relationship between first degree family history of colorectal cancer and some pathological and clinical features was investigated in 302 patients affected by large bowel carcinoma. Patients with inherited forms of polyposis of the large bowel were excluded. Thirty-six (11.

Esophageal dilation in malignant dysphagia.

Esophageal dilation by means of guided Neoplex (Medoc) tubes in 38 patients with malignant obstruction of the esophagus was analyzed. Peroral dilation proved to be a simple, well-tolerated primary procedure in the management of malignant strictures. Most patients have a temporary improvement of dysphagic symptoms, but the benefit appears to decrease progressively in successive dilatatory sessions.
