The expression of TC-PTP mRNA was associated with favorable prognosis in ovarian cancers (THPA database, Log-rank, P <  0.001), but predicted shorter OS in clear cell renal cell carcinoma (THPA database, Log-rank, P <  0.001) based on THPA database using the TCGA database. The gene discussed is PTPN2; the disease is clear cell renal carcinoma.
