• Analysis of Immunostaining during Mohs Micrographic Surgery to Improve Detection of Negative Surgical Margins in Patients with Squamous Cell Carcinoma and Chronic Lymphocytic Leukemia (CLL)/ Non-Hodgkins Lymphoma (NHL) Rochester, Minn.

  The goal of this study is to evaluate the use of immunostains during Mohs micrographic surgery (MMS) will improve detection of negative surgical margins in patients with cutaneous squamous cell carcinoma (cSCC) and chronic lymphocytic leukemia (CLL)/non-Hodgkin lymphoma (NHL). The study will also aim to evaluate the use of immunostains during MMS to improve the outcomes (local recurrence, metastasis, and disease-specific death) in patients with cSCC and CLL/NHL.
