RT Journal Article SR Electronic T1 Circulating Tumor Cells and PET JF Journal of Nuclear Medicine JO J Nucl Med FD Society of Nuclear Medicine SP 1501 OP 1504 DO 10.2967/jnumed.111.097683 VO 52 IS 10 A1 Yu, Jian Q.

The evaluation and monitoring of these therapies require sophisticated laboratory and imaging technologies to detect potential benefit not necessarily translating into significant changes in tumor size. PET has emerged as the most sensitive imaging technique for providing the metabolic profile of an individual tumor. Most recently, the detection of circulating tumor cells in the peripheral blood of patients with advanced malignancies has provided another dimension to the use of PET for sensitive therapeutic monitoring. Moreover, molecular characterization of circulating tumor cells holds promise for furthering the care of cancer patients.
