Low specificity of cytokeratin 19 reverse transcriptase-polymerase chain reaction analyses for detection of hematogenous lung cancer dissemination

Sensitive detection of systemic tumor dissemination in lung cancer patients is important for selection of appropriate treatment modalities. Based on recent promising data that showed reverse transcriptase-polymerase chain reaction (RT-PCR) analyses for cytokeratin 19 (CK-19) expression in peripheral...
