Thymosin beta-4 (Tβ(4)) is a major actin-sequestering molecule that contributes to cell growth, differentiation, motility, survival, mitosis and angiogenesis. It is overexpressed in certain type of carcinoma and fibrosarcoma cell lines and is associated with metastatic potential. The aim of this study was to investigate the relationship between Tβ(4) expression and clinicopathologic features and VEGF status in gastrointestinal stromal tumors (GISTs).

Background And Objectives: Currently, radiotherapy with concomitant and adjuvant temozolomide has become the standard treatment for glioblastoma. The purpose of this study was to report our experience with radiation plus concomitant temozolomide in 116 patients with glioblastoma multiforme (GBM) and examine the value of different prognostic factors.

Design And Setting: Retrospective analysis of 116 patients with newly diagnosed GBM, who were treated at our department between January 1994 and March 2009.

Purpose: In this study, we have examined the correlation between colorectal cancer (CRC) and serum adiponectin and resistin levels, body mass index and insulin resistance.

Methods: The relation between serum adiponectin and resistin levels, obesity and insulin resistance in 36 CRC patients and 37 controls was examined.

Results: Insulin and homeostasis model assessment insulin resistance index (HOMA-IR) levels were higher, and adiponectin levels were significantly decreased in patients versus controls, whereas, resistin levels were significantly increased.

Unlabelled: Chemotherapy provides palliation and modest prolongation of symptom-free survival in metastatic breast cancer. Taxane containing regimens are commonly considered to be among the initials in metastatic setting due to earlier use of anthracyclines in the course of breast cancer. Therefore, we conducted this Phase II study to assess efficacy and safety of gemcitabine plus paclitaxel (GT) combination therapy in anthracycline pretreated metastatic first-line setting.

Insulin resistance (IR) and obesity may be risk factors for breast cancer. The mechanism of IR in patients with cancer has not been fully clarified yet. This study was conducted to evaluate the possible role of circulating cytokines; tumor necrosis factor-alpha (TNF-alpha) and interleukin 6 (IL-6) in inducing IR in 20 overweight or obese patients with early stage breast cancer and to compare their levels with that of body mass index matched 20 healthy controls.

Aim/background: nm23 is suggested to represent a new class of metastasis suppressor genes. An inverse correlation between nm23 expression level and metastatic potential has been demonstrated in different malignancies. This study evaluated the prognostic value of nm23 in gastrointestinal stromal tumors (GISTs).

Aim: In this study we determined the protective role of amifostine against the side effects of the combination of paclitaxel and carboplatin in patients with non-small cell lung cancer (NSCLC).

Patients And Methods: Chemo-naive patients with NSCLC were eligible. Thirty-eight patients were randomized to receive paclitaxel 175 mg/m2 and carboplatin AUC = 6 with amifostine 910 mg/m2 (group B) or chemotherapy alone (group A).
