Effect of Acute Surgical Stress on Serum Ghrelin Levels.

Background: Ghrelin is an appetite hormone that influences the gastrointestinal function and regulates energy metabolism. Growing evidence also suggests that this hormone plays a central role in immune modulation. Each surgical operation is followed by a series of inflammatory and metabolic changes that constitute the stress response.

Lymph node harvesting in colorectal carcinoma specimens.

Introduction: Adequate lymph node evaluation is an important determinant of prognosis in patients with colorectal cancer. Current guidelines recommend evaluation of at least 12 lymph nodes; however, a significant number of patients fail to meet these criteria.

Aim: To investigate the factors that influence adequate recovery and evaluation of lymph nodes in colorectal cancer.

Analysis of clinical and molecular associations of triple negative breast cancers in node-negative patients.

Introduction: Therapeutic modalities in node-negative breast cancer patients remain a matter of controversy. Various prognostic factors have been proposed to help select those patients that would most likely benefit from adjuvant therapy. In view of this notion the triple negative phenotype (hormone receptors and HER2 negative tumors) has gained increasing attention.
