BACKGROUND: Merkel cell carcinoma (MCC) is a rare and aggressive neuro
endocrine tumor of dermal origin, Treatment recommendations are limite
d owing to a paucity of retrospective data and an absence of prospecti
ve data. The objective of this study was to determine current therapeu
tic trends and their impact upon outcome, METHODS: A retrospective stu
dy (1983 to 1996) was performed with patients from the Department of D
efense and our University-affiliate hospitals, RESULTS: Thirty-five pa
tients were evaluated with a mean follow-up of 31 months, Overall, 1-
and 2-year survival rates were 80% and 50%, respectively, Patients und
ergoing wide local excision, prophylactic lymph node dissection, and a
djuvant radiotherapy had significantly decreased locoregional and dist
ant recurrence rates and improved survival when compared with their co
unterparts, Adjuvant chemotherapy did not diminish recurrence rates no
r improve survival. Both locoregional and distant recurrence significa
ntly decreased survival, CONCLUSIONS: These data suggest that early ag
gressive treatment for MCC improves both tumor control and survival, w
hereas the early use of chemotherapy does not improve outcome, (C) 199
