Abstract:
objective To detect CK19 mRNA and CEA mRNA in blood of the peripheral vein and to investigate the effect of ligating pulmonary vein firstly or ligating pulmonary artery firstly during surgical operation on haematogenous dissemination of malignant cells.Methods Fifty six non-small cell lung cancer patients were collected and random assigned to two groups before operation (ligating pulmonary vein firstly or ligating pulmonary artery firstly).The patients were accepted radical operation and their operations were put in practice by doctors of one team.Vein blood was collected one day before operation and one week after operation.CK19 mRNA and CEA mRNA in blood were detected by nested reverse transcriptase-polymerase chain reaction. Result The positive rate of expression of CK19 mRNA and CEA mRNA after operation is lower than that before operation.The positive rate of expression of CK19 mRNA and CEA mRNA in ligating pulmonary vein firstly after operation is lower than that in the other group. Conclusions Surgical operation have effects on the dissemination of malignant cell and ligating palmonary vein firstly during operation can reduce the dissemination of malignant cell.
