To assess the independence and applicability of this four-DNA methylation signature, patients were regrouped according to different clinicopathological characteristics. Over the last few decades, the incidence of CM has been increasing rapidly in males compared to females of all ages, with the exception of young women who appear to be at higher risk than young men (Robsahm et al., 2013). The incidence in male patients is 1.6 times higher than that of female patients, and regrouping was performed based on patients’ sexes and ages at initial diagnosis in the following way: age ?50 (N = 141, %), 50 70 (N = 118, %). 001) longer OS, and the AUC values were more than 0.75 (Figure 3 and Figure 3-figure supplement 1), suggesting that the four-DNA methylation signature is independent of patient sex and age. Considering that once the tumor metastasizes to distant tissues, the 5 year survival rate is very low (Siegel et al., 2018), we regrouped patients based on the site of sample obtainment, including distant metastasis, subcutaneous tissue, and regional lymph node metastasis. Kaplan–Meier and ROC analyses demonstrated that the survival of patients in low-risk groups was much improved in comparison with patients in high-risk groups, and the four-DNA methylation signature had high predictive performance (Figure 3-figure supplement 2). Meanwhile, research has shown that DNA methylation changes in relation to disease stage (Wouters et al., 2017), and survival outcomes can vary widely even at a single stage (Weiss et al., 2015). Because of limited sample size at each stage, patients were separated into early-stage (0 and I and II) and advanced-stage (III and IV) cohorts. Despite the markedly different outcomes in terms of the extent of disease, the OS between high- and low-risk groups are significantly (p Contour step three-source studies dos Given that Breslow density is the most effective prognostic cause for CM, customers that Breslow thickness over dos mm reaches ideal risk of development locoregional cutaneous metastases (Messeguer mais aussi al., 2013), i examined if the four-DNA methylation signature you can expect to identify customers with different endurance risk to own people with assorted Breslow occurrence.

Despite the markedly different outcomes in terms of the extent of disease, the OS between high- and low-risk groups are significantly (p<0.001) different, and the AUC in early-stage and advanced-stage cohorts were 0.814 and 0.809, respectively (Figure 3-figure supplement 3). Furthermore, whether the tumor was located in head and neck or extremity or trunk, the four-DNA methylation signature performed well in differentiating low- and high-risk groups, and patients in high-risk groups showed a trend towards worse OS (Figure 3-figure supplement 4).
