Vulvar melanoma: an analysis of prognostic factors and treatment patterns.

Vulvar melanoma has a poor prognosis for those with regional and distant metastatic disease. Extent of disease, tumor size, and patient age are important prognostic factors. Other favorable factors included insurance and surgical management. The use of immunotherapy has increased over time and may improve survival in those with distant disease. These data support further investigation into the role of immunotherapy for vulvar melanoma to optimize outcomes.
