About this study

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.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
