Similarly, there were no associations of NGF protein expression with that of individual pathological subtypes: compound nevi (CN, h-score = 190.7, IQR 167.5–232.1), dysplastic nevi (DN, h-score = 186.7, IQR 170.6–206.9), thin primary melanomas (TnP, h-score = 146.4, IQR 100.8–166.7), thick primary melanomas (TkP, h-score = 162.2, IQR 94.89–234.8), lymph node metastases (LNM, h-score = 109.1, IQR 62.23–276.7) and distant metastases (DM, h-score = 145.3, IQR 103.9–177.8) (Figure 1H). This evidence concerns the gene NGF and metastatic malignant neoplasm in the lymph nodes.
