Identification of potential serum markers for endometrial cancer using protein expression profiling.

Objectives: Screening method of endometrial cancer (EC) has not been established yet. Our study was to explore serum biomarkers of EC patients using surface-enhanced laser desorption and ionization-time-of-flight mass spectrometry (SELDI-TOF MS).

Methods: Serum samples from 65 EC patients and 40 controls were analyzed by SELDI-TOF MS (training set).
