摘要: A series of eight microsatellite loci were assayed for both loss heterozygosity and new mutated alleles in 91 head neck squamous cell carcinomas. In 58 cases, alterations detected used as markers assaying the presence circulating tumor-derived DNA patients' plasma. This was unambiguously 17 cases. The probability detecting independent tumor stage found to be present even some individuals with I tumors. such DNA, however, could not correlated disease outcome or other significant clinical parameters, suggesting that it has no prognostic significance. results indicate a means early diagnosis
