Role of Positron-Emission Tomography Scan in the Diagnosis and Management of Breast Cancer

March 17, 2009

In 2008, more than 184,000 new patients were diagnosed with breast cancer, the most commonly diagnosed malignancy in women in the United States. Despite great advances over the past few years in screening, detection, and treatment, more than 40,000 women died from the disease in 2008.[1] Early breast cancer is considered a curable disease, but the curative potential of patients with locally advanced or metastatic disease is limited.

Role of Tumor Markers and Circulating Tumors Cells in the Management of Breast Cancer

June 01, 2008

Along with various imaging modalities, serologic tumor markers such as CA 15-3 and CA 27.29 have been used for decades to monitor treatment response in patients with metastatic breast cancer (MBC). Despite the frequent use of these markers, they lack high sensitivity and specificity for breast cancer progression. The prognostic significance of these markers remains indeterminate because of the conflicting outcome of many clinical trials. The circulating tumor cell (CTC) test has recently been studied in clinical trials in patients with MBC. Some of the studies showed that high levels of CTCs are correlated with poor survival in MBC. An intergroup trial is underway to determine the implication of changing treatment based on the CTC level. This article will discuss the current data on these markers, with special emphasis on the CTC test. The potential clinical utility of these markers will also be discussed.
