Comparison of results with CO2 laser and traditional surgical treatment of stage I malignant melanoma.
The follow-up data on 39 cases of stage I malignant melanoma treated with CO2 laser are compared to those of an analogous group of cases treated by traditional surgical methods and selected for their clinical and pathologic similarities with the laser-treated group. The findings were expressed in terms of tumor-free time and were evaluated by variance analysis. The data showed that traditional methods gave better results. CO2 laser surgery requires longer healing time, which may have a negative effect on the course of the disease.
