Correlation of Hormone Receptor Expression with Histologic Parameters in Benign and Malignant Breast Tumors
Background and Objective: Breast cancer is the commonest cancer of Indian women. Estrogen and Progesterone expression is seen in benign breast lesions and in breast carcinoma associated with good prognostic parameters and it correlates well with response to hormone therapy. Although a lot of studies have been conducted in the past on hormone receptor expression in breast cancer and few have cor...
متن کاملSerotonin and pancreatic duct function.
1. 5-HT inhibits spontaneous fluid secretion as well as stimulated secretion with secretin (cAMP mediated) or ACh (Ca2+ mediated) in the isolated guinea pig pancreatic ducts. 2. The inhibitory effect of 5-HT is reversible and is dependent on the concentration in the range 0.01-0.1 microM, which is much lower than those that affect intestinal motility and secretion. 3. The 5-HT3 receptor in duct...
متن کاملPancreatic carcinoids (serotonin-producing pancreatic neuroendocrine neoplasms)
INTRODUCTION Pancreatic neuroendocrine neoplasms (pNENs) are relatively rare tumors representing 1% to 2% of all pancreatic neoplasms. These tumors can secrete a variety of biologically active substances giving rise to distinct clinical symptoms or can be clinically nonfunctioning. Apart from insulinomas and gastrinomas, which constitute the majority of functioning pNENs, some tumors may secret...
متن کاملPancreatic Neuroendocrine Tumors
Pancreatic neuroendocrine tumors are usually indolent (slow-growing) by nature and develop over the course of many years. Pancreatic neuroendocrine tumors are usually more indolent, with better prognosis than adenocarcinoma of the pancreas (Carriaga & Henson, 1995). However, aggressive, fast growing pancreatic neuroendocrine tumors exist and different types of pancreatic neuroendocrine tumors e...
متن کاملBiomarkers in pancreatic neuroendocrine tumors.
The aim of biomarkers is to identify patients most likely to benefit from a therapeutic strategy. Pancreatic neuroendocrine tumors are rare neoplasms that arise in the endocrine tissues of the pancreas. Pancreatic neuroendocrine tumors represent 3% of primary pancreatic neoplasms and their incidence has risen. The SMAD4 gene is located on chromosome 18q and someday the SMAD4 gene status may be ...
