SnapShot: Circulating Tumor Cells
Circulating tumor cells in the blood of patients are both signal flares for the existence of a tumor and harbingers of metastasis. With recent technological developments, these cells can be isolated and analyzed to provide insights into the biology of cancer spread and response to therapy and to offer new avenues for blood biomarker development.
متن کاملCirculating tumor cells.
A typical cancerous tumor contains millions or even billions of cells harboring genetic mutations driving them to grow, divide, and invade the local tissue in which they’re embedded. However, as the cells proliferate, they don’t all stay in the neighborhood. Some cells slough off the edges of a tumor and are swept away by the bloodstream or lymphatic system. These so-called circulating tumor ce...
متن کاملCirculating Tumor Cells.
Circulating Tumor Cells (CTC) are shed from primary or secondary tumors. Prior studies have demonstrated that enumeration of CTC is a robust independent prognostic factor of progression free and overall survival in patients with early and metastatic breast cancer. CTC, as well as other circulating tumor markers, have the appealing advantages over tissue biopsy of (1) ease of collection, (2) ser...
متن کاملCirculating Tumor Cells and Tumor Dormancy
Metastatic cancer can recur months or even years after apparently successful treatment of the primary tumor. While the exact mechanisms leading to cancer recurrence remain poorly understood, failure to completely eliminate dormant micrometastases and solitary metastatic cells is believed to be a major contributor. Thus, while not of initial clinical concern, metastatic dormancy is still a signi...
متن کاملDetection of Circulating Tumor Cells
The increasing number of treatment options for patients with metastatic carcinomas has created an accompanying need for methods to determine if the tumor will be responsive to the intended therapy and to monitor its effectiveness. Ideally, these methods would be noninvasive and provide quantitative real-time analysis of tumor activity in a variety of carcinomas. Assessment of circulating tumor ...
