Summary
Malignant melanoma incidence in Puerto Rico increased between 1981-1987, with most cases on extremities. Superficial spreading melanoma was most common, but data on tumor depth and patient age varied.
Area of Science:
- Epidemiology
- Dermatology
- Oncology
Background:
- Malignant melanoma is a significant public health concern.
- Understanding regional incidence and characteristics is crucial for targeted prevention and treatment strategies.
Purpose of the Study:
- To determine the incidence and clinico-histologic characteristics of malignant melanoma in Puerto Rico.
- To compare current findings with previous epidemiological data for the region.
Main Methods:
- Review of the Puerto Rico Cancer Registry for melanoma cases diagnosed between 1981 and 1987.
- Analysis of demographic, tumor location, and clinico-histologic data.
Main Results:
- A total of 367 new cases were documented, with an average annual incidence of 1.59 per 100,000 population.
- The highest incidence was observed in patients in their sixties, with tumors frequently located on the extremities, particularly the feet.
- Superficial spreading melanoma was the most common subtype, though a significant proportion of cases lacked detailed histologic classification.
Conclusions:
- The incidence of malignant melanoma in Puerto Rico showed an increase compared to earlier periods.
- Extremity and foot locations were common, suggesting potential environmental or genetic factors.
- Incomplete reporting of histologic details highlights a need for improved data collection in cancer registries.
