We used data from tumor samples taken from Chinese patients with melanoma analyzed at the Geneplus Institute (n=302), as well as data from the Cancer Genome Atlas (TCGA) database (n=367) and the Memorial Sloan Kettering Cancer Center (MSKCC) database (n=350) to estimate the prevalence of CCND1 amplification in melanoma, interrogate the relationship between CCND1 amplification and survival in patients with melanoma, and explore the molecular mechanisms of CCND1 amplification. Here, CCND1 is linked to neoplasm.
