A 54 years old female with history of total thyroidectomy for papillary carcinoma, treated with lOOmCi of iodine-131 and negative whole body scans was referred for follow up study. Tl-201 scan revealed an area of radiotracer uptake in the neck region, suggestive of a parathyroid adenoma versus recurrence of thyroid carcinoma. The patient was operated, the parathyroid adenoma was removed. ...

mucinous carcinoma of the breast is a well-differentiated type of adenocarcinoma accounting for 2-5% of all breast cancers. pure mucinous carcinoma of the breast has a favorable prognosis, usually seen in post-menopausal women. neuroendocrine differentiation has been described in both in-situ and infiltrating breast cancers .mucinous carcinomas of the breast appear to have the greatest associat...

background the process of neoplastic transformation in the stomach has been reported to be associated with decreased expression of normal mucins of the gastric mucosa and denovo expression of mucins that are normally expressed in other organs. this association may be used as a means to bring new insights into biologic behavior and genetic pathways in the development of gastric cancer. there are...

cadmium has been known to be harmful to human health, mainly via contaminated drinking water, food supplies, tobacco and industrial pollutants. the aim of this study was to determine the ability of cadmium chloride (cdcl 2 ) to cause cell death in the human lung carcinoma cell line (calu-6). the cells were grown in rpmi-1640 medium supplemented with 10% fcs, penicillin/streptomycin (100 u/ml, 1...

context primary liver cancer is one of the most common and deadly malignant neoplasms worldwide. the incidence and mortality rates for hepatocellular carcinoma (hcc) are virtually identical, reflecting the poor overall survival of patients with this kind of tumor. effective therapies mostly achieved if the hcc diagnosis is made at early stages of the tumor. surveillance tests include serologic ...

contexts hepatocellular carcinoma (hcc) is one of the most common malignant diseases in the world. because less than 20% of patients with hcc are resectable, various types of non-surgical treatment have been developed. evidence acquisition at present, radiofrequency ablation (rfa) is accepted as the standard local treatment for patients with hcc because of its superior local control and overall...

cancer starts with a change in one single cell. this change may be initiated by external agents and genetic factors. cancer is a leading cause of death worldwide and accounts for 7.6 million deaths (around 13% of all deaths) in 2008. lung, stomach, liver, colon and breast cancer cause the most cancer deaths each year. in this review, different aspects of gastric cancer; including clinical, path...
