Mohs micrographic surgery: 10 year experience in Puerto Rico
Puerto Rico Health Sciences Journal
|March 27, 2014
Summary
Mohs micrographic surgery (MMS) for nonmelanoma skin cancer (NMSC) saw a 44% increase in use over 10 years. Treatments in 2010 showed larger defects and more flap repairs compared to 2000, despite similar tumor characteristics.
Area of Science:
- Dermatology
- Surgical Oncology
Background:
- Nonmelanoma skin cancer (NMSC) incidence is rising globally.
- Mohs micrographic surgery (MMS) is a standard treatment for NMSC, particularly on the face.
- Treatment modalities for NMSC have diversified over time.
Purpose of the Study:
- To compare changes in NMSC characteristics treated with MMS over a 10-year period.
- To evaluate modifications in surgical defect repair patterns following MMS.
- To analyze trends in MMS utilization at the University of Puerto Rico dermatology clinics.
Main Methods:
- Retrospective chart review of patients treated with MMS in 2000 and 2010.
- Analysis of patient demographics, lesion location, pathology, and tumor/defect sizes.
- Comparison of preoperative tumor characteristics and postoperative repair methods.
Main Results:
- MMS treatment increased by 44% from 2000 to 2010.
- Tumor types, preoperative sizes, and locations (head/neck, nose) remained similar between cohorts.
- Postoperative defects were smaller in 2000 than in 2010; flap repairs increased significantly in 2010.
Conclusions:
- A trend towards larger defects and reconstruction with flaps was observed in 2010.
- Fewer surgical stages were needed for tumor excision in 2010 compared to 2000.
- The study highlights evolving patterns in MMS treatment for NMSC.
