Before carrying out the research, we have found that some LOX family genes, such as LOX and LOXL2, were significantly correlated with poor prognosis in many types of solid tumors (eg, bladder urothelial carcinoma, lung squamous cell carcinoma, and skin cutaneous carcinoma) using the online web tool ESurv, which was a user‐friendly web tool for survival analysis.17 The gene discussed is LOX; the disease is bladder transitional cell carcinoma.
