MFAP2 is important in the prognosis of the above tumor types; however, the specific mechanism and prognostic value of MFAP2 in other cancers with low expression of MFAP2, such as Kidney chromophore, Kidney renal clear cell carcinoma, Kidney renal papillary cell carcinoma, and Prostate adenocarcinoma, need to be further explored. The gene discussed is MFAP2; the disease is prostate adenocarcinoma.
