Planar fluorescence imaging using normalized data.

Fluorescence imaging of tissues has gained significant attention in recent years due to the emergence of appropriate reporter technologies that enable noninvasive sensing of molecular function in vivo. Two major approaches have been used so far for fluorescence molecular imaging, i.e.

Five-year update of an expanded phase II study of dose-dense and -intense doxorubicin, paclitaxel and cyclophosphamide (ATC) in high-risk breast cancer.

Objectives: This study evaluated the safety and efficacy of dose-dense and -intense sequential doxorubicin (A), paclitaxel (T) and cyclophosphamide (C) as adjuvant therapy for breast cancer (BC) with >or=4 ipsilateral axillary lymph nodes.

Methods: Patients were recruited after BC surgery if >or=4 axillary nodes were involved by metastatic cancer. Planned treatment was A 90 mg/m(2) three times every 14 days (q14d x 3), T 250 mg/m(2) q14d x 3 and C 3 g/m(2) q14d x 3 combined with filgrastim support.

Use of gene expression profiling to direct in vivo molecular imaging of lung cancer.

Using gene expression profiling, we identified cathepsin cysteine proteases as highly up-regulated genes in a mouse model of human lung adenocarcinoma. Overexpression of cathepsin proteases in these lung tumors was confirmed by immunohistochemistry and Western blotting. Therefore, an optical probe activated by cathepsin proteases was selected to detect murine lung tumors in vivo as small as 1 mm in diameter and spatially separated.
