OBJECTIVE: In order to establish a primary diagnosis model of laryngeal carcinoma, we explore the changes of proteomic spectra in serum from patients with laryngeal carcinoma and healthy controls.
METHOD: Proteomic spectra of 32 serum samples from laryngeal carcinoma (18 cases of glottis and 14 of supraglottis) patients and 38 from healthy people whose age and sex was matched were generated by IMAC3-Cu protein chip array and SELDI-TOF-MS (surface was enhanced laser desorption/ionization time-of-flight mass spectrometry). The discriminatory profiling between cancer and normal samples was analyzed by Biomarker Wizard software and Biomarker Pattern software.
RESULT: Fifteen differentially expressed proteins in serum were screened by analysis of proteomic spectra of preoperative patients and normal subjects. Eight proteins (3795.04, 5068.18, 5339.78, 5908.28, 6629.74, 9266.32, 13879.6 and 14037.1) were obtained for making up patterns that was able to class the patients team and normal team correctly. Corresponding correct ratio were 87.50% (28/32) and 86. 84% (33/38).
CONCLUSION: SEI.DI-TOF-MS Protein Chip technology is a new tool for the early diagnosis of laryngeal carcinoma.
