Melanoma astrocytoma syndrome

From WikiMD's Wellness Encyclopedia

Other Names: Melanoma and neural system tumor syndrome An extremely rare, inherited disorder in which affected people have an increased risk of developing melanoma and nervous system tumors, especially astrocytoma (a type of brain tumor). The tumors tend to develop at an early age, and one or both types of tumors may occur in the same person. Also called melanoma and neural system tumor syndrome.

Cause[edit | edit source]

Melanoma-astrocytoma syndrome is caused by mutations (changes) in the CDKN2A gene.

Epidemiology[edit | edit source]

Prevalence and incidence rates are not known. Fewer than 20 affected families have been reported to date. Cases have been reported from France, Italy, the UK and the USA.

Clinical description[edit | edit source]

In reported families, affected individuals had cutaneous melanoma in association with dysplastic nevi, astrocytoma, benign or malignant peripheral nerve sheath tumor, neurofibroma, medulloblastoma, glioblastoma multiforme, ependymoma, glioma, and meningioma (see these terms). In some cases, melanoma was described first followed by nervous system tumors, and in other cases, melanoma was a secondary cancer.

Etiology[edit | edit source]

The etiology of this tumor association is unknown. Genetic mutations or germline deletions are thought to underlie this cancer susceptibility syndrome.

Genetic counseling[edit | edit source]

Male-to-male transmission was reported in one family but inheritance patterns are not clearly characterized. The increased risk appears to be found in both first- and second-degree relatives.

Treatment[edit | edit source]

The medication(s) listed below have been approved by the Food and Drug Administration (FDA) as orphan products for treatment of this condition.

  • Aldesleukin (Brand name: Proleukin)Treatment of adults with metastatic melanoma.
