ABSTRACT
<p><b>OBJECTIVE</b>To explore the early detection of breast cancer by ultrasonic imaging and thermal tomography of luciferase or green fluorescent protein (GFP)-labeled MDA-MB-231 breast cancer cell line-xenografts in nude mice.</p><p><b>METHODS</b>Fluorescence-tagged lentiviral vectors were transfected into the triple-negative breast cancer cell line MDA-MB-231. These cells were implanted either subcutaneously under the right breast pad or intravenously into the tail vein of nude BALB/C mice. Thermal tomography and ultrasound imaging were used to detect tumor formation and to monitor tumor growth and metastasis in vivo.</p><p><b>RESULTS</b>Triple negative breast cancer cell line-xenografts were used to successfully construct an orthotopic nude mice model of breast cancer metastasis in the peritoneum. Thermal tomography and ultrasound imaging were used together to detect small tumors. Thermal tomography imaging detected small tumors earlier than ultrasound imaging.</p><p><b>CONCLUSIONS</b>Thermal tomography can be used to monitor changes in tumor growth and detect abnormal tissue. Therefore, it can serve as a convenient,rapid,sensitive, and reliable technique for early screening of human breast cancer.</p>
