In addition, melanomas expressing lower than the mean XPC (XPC-) had 164.14 (95% CI 115.82 - 212.46) median weeks survival compared to 547.29 (95% CI 142.12 - 952.45) median weeks survival for those with high XPC expression (XPC+) (χ2 = 4.34 p = 0.037) (Figure 5). This evidence concerns the gene XPC and melanoma.
