Abstract:
Objective To investigate the relationship of tumor malignancy with Na+ microcurrent measured by microcurrent detector in order to develop a novel approach for rapid intraoperative diagnosis of tumor.Methods 101 cases of various tumors were studied.Na+ microcurrent of tumor tissue or surrounding normal tissue was measured by Na+ microcurrent detector.All tumor tissues were sampled for histopathological examination as well.Results In 97 cases(96%),the Na+ microcurrent level in tumor tissue was significantly different from that in surrounding normal tissue.It was greater than 30?A in tumor tissue with the maximum of 60-70?A,and averagely 20?A in surrounding normal tissue.The consistency of Na+ microcurrent detection and pathological examination was 96%.Conclusion the measurement of Na+ microcurrent by microcurrent detector is rapid,convenient and accurate,which may become a novel approach for rapid intraoperative diagnosis of tumor malignancy.
