Prognosis for women diagnosed with melanoma during, before, or after pregnancy: Weighing the evidence

Abstract

Approximately one third of women who are diagnosed with malignant melanoma are of childbearing age. Therefore, it is not surprising that some studies have found malignant melanoma to be one of the most common malignancies diagnosed in pregnant women. The impact of pregnancy-related hormonal changes on melanoma development and progression remains controversial. Women undergo immunologic changes during pregnancy that may decrease tumor surveillance. Additionally, hormone receptors are found on some melanomas. Unfortunately, many of the past and even recent studies that have been published and are reviewed herein did not uniformly use appropriate control groups, account for confounding covariates, or employ appropriate statistical analysis, which makes it difficult to rely on the conclusions they reach. However, a review of the better controlled and preponderant studies demonstrates that pregnancy-associated melanomas are not associated with a poorer prognosis.
