Supplemental Figures and Tables: Clinicohistopathologic profile of patients who underwent Mohs micrographic surgery at the Dermatology Center of St. Luke’s Medical Center, Philippines from March 2003 - March 2018

ABSTRACT BACKGROUND Mohs Micrographic Surgery (MMS) has proven to be an effective technique in microscopically removing tumor foci while sparing normal tissue. OBJECTIVE To describe the clinical and histopathologic profile of patients who underwent MMS at the Dermatology Center of St. Luke’s Medical Center from March 2003 - March 2018. METHODS A retrospective review of MMS cases at the Dermatology Center from March 2003-March 2018. RESULTS Of 476 total MMS cases treated from 2003 to 2018, 404 cases with complete data were included. Mean age of the study population was 64.8 years old, with 94.9% in the >40 age group. Two hundred forty-two patients were Asians. The most common tumor was basal cell carcinoma (78%). More than half of cases (65.1%) were cleared of tumor after 2 stages. Based on the 5-year surveillance, there has been no recurrence of primary cases as of 2018. There were 2 (6.89%) recurrences amongst 29 recurrent tumors. LIMITATIONS This study is limited to MMS patients operated on at the Dermatology Center of St. Luke’s Medical Center. CONCLUSION The clinicohistopathologic profile of patients who underwent MMS is reflective of local, regional and international data. Post-operative data and surveillance prove that MMS is both a conservative and reliable approach to treatment of NMSCs.
