Plantar acral melanoma--an experience from a regional cancer centre, India.

This is a retrospective analysis of all plantar acral melanomas treated at the Cancer Institute (WIA) Madras between January 1981 and December 1990. Acral melanomas constitute 26% of all melanomas in this population, the sole of the foot being the dominant site (35 of 36 cases). We have found that it is more common in the lower socioeconomic strata, occurs often over weight bearing areas and is usually advanced at presentation. The projected five year survival was 51% while the five year disease free survival was only 22%. Pathological nodal status was found to be the only factor significantly influencing survival in this study. Wide local excision was found to give results equivalent to radical amputation and is strongly recommended since it gives a much better quality of life with a disease that has an overall dismal prognosis.
