|Condition or disease||Intervention/treatment||Phase|
|Head and Neck Squamous Cell Carcinoma||Drug: Panitumumab-IRDye800 Drug: Lymphoseek||Phase 2|
I. To determine if near-infrared fluorescence imaging of panitumumab-IRDye800 can identify metastatic disease in regional neck lymph nodes of patients with head and neck squamous cell carcinoma (HNSCC).
I. Determine if panitumumab-IRDye800 can identify sentinel nodes with the same accuracy as technetium Tc 99m-labeled tilmanocept (Lymphoseek).
Beginning 2-5 days before surgery, patients receive panitumumab IRDye800 intravenously (IV) over 60 minutes. On the day before surgery, patients also receive technetium Tc 99m-labeled tilmanocept via injection and undergo lymphoscintigraphy and single photon emission computed tomography/computed tomography (SPECT/CT).
After completion of study, patients are followed up for 30 days.

Experimental: T1 or T2 stage and node negative
T1 or T2 stage primary tumor and node negative (i.e., cN0)
50 mg infusion
2 mCi, infusion
Experimental: Any T stage and node positive
Any T stage tumor and node positive (i.e., cN+)
50 mg infusion
- Number and location of panitumumab-IRDye800 positive lymph nodes (LNs) that are also tumor- positive at (histo-) pathology [ Time Frame: Up to 30 days ]The sensitivity and specificity of the intraoperative findings on whether the LN is fluorescent (i.e. presence of panitumumab-IRDye800) to the histopathological status of the LNs will be calculated. Significance for both primary and secondary analyses will be assessed at the 0.05 level and to assess uncertainty, 95% confidence intervals will be provided for all estimates.
- The number and location of Lymphoseek positive lymph nodes (LNs) that are also tumor-positive at (histo-) pathology [ Time Frame: Up to 30 days ]Whether the LN tracer Lymphoseek can identify metastatic disease in regional neck LNs of patients with head and neck squamous cell cancer will be determined. Similar to the primary analysis, the specificity and sensitivity of Lymphoseek for metastatic LN identification, using histology will be calculated, and compared to neck dissection with Durkalski's test.
