Filter by:This study will compare TNFE-NBI and biopsy, with DRE and biopsy for the diagnostic evaluation and staging of patients with suspicious UADT lesions. All patients enrolled in the study will undergo TNFE-NBI with biopsy of suspicious lesions prior to planned regular clinical care (DRE). Biopsies will be evaluated by standard clinical methods for patient diagnoses and care. As the current standard of care, if all biopsies for a given patient are non-malignant, a 3 month office visit will be arranged to evaluate and determine the need for further intervention. At the end of study enrollment both sets of biopsies will be re-evaluated in a blinded fashion by the surgical pathologist. Study assessment of malignant vs. non-malignant (benign) pathology will be used to see whether both tests tended to agree on diagnoses.
The objectives for this study is as follows: - Primary: - To evaluate the progression-free survival of locoregionally advanced (stages III/IV) SCCHN patients undergoing postoperative chemoradiotherapy with panitumumab. - Secondary: - To evaluate the overall survival, event-free survival, and toxicities. - To correlate efficacy parameters with 1) EGFR and downstream pathway activation, 2) FcyR polymorphisms, and 3) serum cytokine profiles. More specifically, the aim is to demonstrate the usefulness of biomarkers (downstream signaling molecules, FcyR polymorphisms, or tumor and serum cytokine(s) in predicting progression-free survival in patients with SCCHN treated with the above treatment. Specific biomarkers that relate to Epidermal Growth Factor Receptor and angiogenesis, including EGFR, pEGFR, Src, pMAPK, pSTAT3, pSTAT5, pSTAT1, pAKT, p38, p21, p27, PARP, E-cadherin, p-ErbB3, Ki67, VEGF, and IL-8, using reverse phase protein microarrays (RPPA) will be tested in baseline archival paraffin-embedded tumor tissue. To collect tumor tissue from pretreatment biopsies for cytokine/chemokine and immune biomarker studies on tumor tissue. We plan to investigate the expression of pAKT, pMAPK, and other EGFR pathway-related markers as well angiogenesis biomarkers. In addition, EGFR polymorphisms will be studied in tumor tissue samples and serum. Additional studies may be performed in the future. Some of these studies may be performed by Amgen.
