Prognosis for cutaneous melanoma according to surgical department: comparative study at a tertiary care hospital

IntroductionSurgical treatment of melanoma is performed by dermatologists and general or plastic surgeons. It is not known whether the type of specialist treating the melanoma results in a different prognosis for these patients.Material and methodsA retrospective study was carried out on the epidemiological, clinical/histological and evolutional characteristics of all patients diagnosed with melanoma at Hospital Gregorio Marañón over a 10-year period (1994--2003). The differences by hospital department where the patients were treated (dermatology, general surgery and plastic surgery) were noted.ResultsOver 90 % of the patients with melanoma were treated by the Dermatology Department. The thickness of the tumors and the presence of histologic ulceration were significantly higher in the melanomas treated by general and plastic surgeons (p < 0.05). The differences in overall average survival (105, 55 and 77 months) and disease-free time (88, 24 and 51.3 months) in the melanomas operated on by dermatologists, general surgeons and plastic surgeons, respectively, were significant (p < 0.001).ConclusionsThis study confirms that there are significant differences in the clinical and histological characteristics and the life prognosis of patients with cutaneous melanoma treated by different specialists. The melanomas treated by general or plastic surgeons have usually been developing for a longer time, and therefore are thicker and more often ulcerated than those treated by dermatologists, resulting in a lower survival period. With appropriate medical and surgical training, dermatologists are the most suitable specialists for early diagnosis and treatment.
