Summary

Current imaging devices usually detect cancer prior to surgery. However, these devices cannot be used during the surgical procedure to visualize lymph nodes with cancer (called "sentinel lymph nodes"). This is a Phase II study, containing a total of 67 patients with head and neck cancer. The purpose of this study is to test if imaging, with cRGDY-PEG-Cy5.5-C dots is useful for evaluating your type of cancer. This is currently not approved by the FDA. The researchers want to see if cRGDY-PEG-Cy5.5-C dots, can improve upon the usual scans. As a part of your standard of care, you will initially undergo imaging of your lymph nodes prior to your surgery. Prior to your surgery, you will be injected with a radioactive dye around the tumor site, and images will be acquired about 2 hours later using a device to image the location of the dye. We have tested, for the first time in humans, a new, experimental dye-labeled particle (dots), cRGDY-PEG-Cy5.5-C dots for lymph node mapping. This particle, the size of a small protein, will be injected around sites of your tumor before or during your surgery to identify diseased nodes using a hand-held camera system. The dye-labeled particle can be viewed in tissues that may contain tumor. The particles will not treat your cancer and any images or information found during this study will not be used for your treatment. The information collected may be used to guide the design of future studies to detect and/or treat tumors.

Criteria

Inclusion Criteria:

• 18 years of age or older

• Histologically confirmed diagnosis of melanoma at MSKCC

• Have one of the following disease histories:

• Newly-diagnosed or recurrent (local, regional, metastatic) malignant melanoma, oral cavity squamous cell carcinoma, and squamous cell carcinoma of the skin patients in whom SLN mapping is indicated

• Residual clinically or radiographically evident tumor, including primary cutaneous and mucosal melanomas

• Prior radiation therapy, chemotherapy, or surgery in patients requiring flap reconstruction in the head and neck region.

• Newly diagnosed patients with previous excisional biopsy.

• At the discretion of the physician or surgeon, normal baseline cardiac function based upon pre-operative evaluation

• At the discretion of the operating surgeon, ANC>1000/mcl and platelets>100,000/mcl.

• At the discretion of the physician or surgeon, bilirubin level of < 2.0 mg/dl in the absence of a history of Gilbert's disease (or pattern consistent with Gilbert's).

• For melanoma patients, if patients have a history of malignancy other than melanoma, and other skin cancers in the past five years, their inclusion is up to the discretion of the physician.

• All patients of childbearing and child-creating age must be using an acceptable form of birth control

• Women who are pre-menopausal must have a negative serum pregnancy test

Exclusion Criteria:

• Known pregnancy or breast-feeding.

• Medical illness unrelated to the tumor which in the opinion of the attending physician and principal investigator will preclude administration of the agent. This includes patients with uncontrolled infection, chronic renal insufficiency, myocardial infarction within the past 6 months, unstable angina, cardiac arrhythmias other than chronic atrial fibrillation and chronic active or persistent hepatitis, or New York Heart Association Classification III or IV heart disease.
