Expression and potential role of ErbB receptors in type II endometrial cancer.

Objective: Endometrial cancer is the most common malignancy of the female genital tract. Based on clinical and pathological features, endometrial cancer is classified into two types. The aim of our study was to describe the expression and the potential clinical role of ErbB receptors in Greek patients with type II endometrial cancer.

Complications and risk factors related to the extent of surgery in thyroidectomy. Results from 2,043 procedures.

Objective: To evaluate the rate of complications and the risk factors in relation to the extent of surgery in patients undergoing thyroidectomy in a tertiary university center.

Design: Data were collected retrospectively from 2,043 consecutive patients who underwent thyroid surgery for various thyroid diseases at the University Hospital of Patras, Greece, between January 1996 and December 2007. Recurrent laryngeal nerve palsy (RLNP) and hypoparathyroidism were set as the primary end points, while hematoma and wound infection were set as the secondary endpoints.

The potential role of Bcl-2 expression, apoptosis and cell proliferation (Ki-67 expression) in cases of gastric carcinoma and correlation with classic prognostic factors and patient outcome.

Background: This study investigated the presence of apoptosis and proliferation in gastric cancer and assesses their possible correlation with classic prognostic markers and patients' survival.

Patients And Methods: The study comprised 110 patients with gastric carcinoma who underwent gastrectomy for therapeutic reasons, and did not receive any pre- or postoperative treatment. Patients were followed up for 3.

Oval cell proliferation in cirrhosis in rats. An experimental study.

Aim: Oval cells are liver stem cells involved in liver regeneration following liver damage. Previous studies have shown that pretreatment with a hepatocyte inhibitor is required to allow full oval cell activation. This study investigates whether oval cells develop and proliferate in a model of experimental liver fibrosis without pretreatment with a known hepatocyte inhibitor.

Potential role of hepatic progenitor cells expression in cases of chronic hepatitis C and their relation to response to therapy: a clinicopathologic study.

Background: This study investigates the correlation of hepatic progenitor cells (HPC) expression with treatment response in patients with chronic hepatitis C.

Design: The study comprised 77 liver biopsies with chronic hepatitis C (HCV). All patients were PCR-HCV (+) and received antiviral therapy with interferon or pegylated interferon alpha-2b and ribavirin.
