MALAT1 and cutaneous melanoma: The results showed that the overall survival time and disease-free survival time of the patients with MALAT1 or LINC00943 CNV deficiency were significantly lower than those without it, and the difference was significant (details are shown in Table 8 and Fig. 9a-d), suggesting that MALAT1 and LINC00943 are independent risk factors for the prognosis of cutaneous melanoma.
