To explore whether OLFML2B has the same prognostic ability in other cancers, the Kaplan-Meier analysis of OLFML2B in 33 cancers can be queried in the web tool “SangerBox.” We found that OLFML2B had statistical significance in adrenocortical carcinoma, bladder urothelial carcinoma, breast invasive carcinoma, kidney renal clear cell carcinoma, kidney renal papillary cell carcinoma, lung adenocarcinoma, ovarian serous cystadenocarcinoma, sarcoma, stomach adenocarcinoma, thyroid carcinoma, and uveal melanoma (P < 0.05; Supplementary Figure S1). The gene discussed is OLFML2B; the disease is invasive breast carcinoma.
