Comparison of Elective Lymph Node Treatment Versus Clinical Observation in the Absence of Palpable Lymph Nodes for High Risk Skin Squamous Cell Carcinoma (SCC)
- Conditions
- High Risk Cutaneous Squamous Cell Carcinoma
- Interventions
- Procedure: elective lymph node dissection
- Registration Number
- NCT01252329
- Lead Sponsor
- University of Pittsburgh
- Brief Summary
This study will evaluate if there is a difference in survival between elective treatment of draining lymph nodes vs. clinical nodal observation in patients undergoing Mohs surgery for high risk skin squamous cell carcinoma of the head and neck who have a normal lymph node exam. Each treatment arm is accepted as a current standard of care, and the objective is to compare outcomes between the two arms.
- Detailed Description
This is a prospective, randomized, non-blinded, controlled trial of high risk head and neck cutaneous squamous cell carcinomas which will compare specific outcomes between two treatment arms. Subjects are eligible patients who are sent to Zitelli \& Brodland PC for Mohs micrographic surgery of tumors that meet our high risk criteria. These patients with clinically-negative lymph node exams will either enter into the arm of nodal observation or the arm of elective management of the neck, which is currently the standard protocol per the UPMC ENT department. The patients in the observation arm will have evaluation and treatment of their lymph nodes if an abnormality is detected clinically. The primary endpoint is disease-specific survival. Secondary endpoints will include overall and disease-free survival, complications, and quality of life measures for each arm.

Group Intervention Description Elective lymph node treatment arm elective lymph node dissection Patients entering this arm will undergo selective nodal dissection of the draining lymph nodes with subsequent radiation and/or chemotherapy if indicated.
- Primary Outcome Measures
Name Time Method Disease-specific survival 5 years
- Secondary Outcome Measures
Name Time Method Overall survival 5 years Disease-free survival 5 years Complications 5 years This refers to any adverse event or side effect related to any of the study interventions.
quality of life 5 years This refers to quality of life measured with a standard questionnaire. The two arms will be compared with respect to their differences (if any) in quality of life.
