The role each prognostic variable their independent effect were using Cox model. Disease-free (DFS) overall (OAS) survival curves estimated Kaplan-Meier method.RESULTSAs November 30, 1994, median follow-up period 12 years. 43 (29.7%), which directly correlated with tumor size inversely estrogen receptor (ER) level. At univariate analysis, did not affect either DFS OAS; had a on reducing risk rec...
