## Abstract Tumor cells were first shown to exhibit a distinct metabolic phenotype over 80 years ago. Since then, it has become clear that multiple oncogenic events contribute to the development of a metabolic phenotype that supports rapid proliferation. Because this phenotype represents an essenti

Abstract
Background
Nanotechnology‐based drug delivery approaches may help increase therapeutic efficacy and decrease side effects of chemotherapeutics. We investigated expression levels of folate receptor in squamous cell carcinoma of the head and neck (SCCHN) to evaluate folate receptor as a target for nanotherapy.
Methods
Folate receptor expression levels in archival SCCHN tissues were analyzed by immunohistochemistry and correlated with clinical parameters.
Results
Folate receptor was detected in 45% of primary tumors and 40% of corresponding lymph node metastases. Folate receptor expression in primary tumors of the metastatic group strongly correlated with the corresponding lymph node metastases (p = .0002). Folate receptor expression was inversely correlated with disease‐free survival in nonmetastatic (p = .0048), metastatic (p = .0127), and lymph node metastases (p <.001) groups, and with overall survival in the lymph node metastases group (p <.0001).
Conclusion
Folate receptor is expressed in a significant proportion of primary SCCHN and corresponding lymph node metastases tissues, and correlates with worse clinical outcome. These findings provide support for folate receptor‐mediated nanotherapeutics in SCCHN. © 2008 Wiley Periodicals, Inc. Head Neck, 2009
