A direct measurement of serum amylase levels produced by lung cancer.
The production of amylase by lung cancer has been previously diagnosed pathologically or immunohistochemically, or it has been confirmed by a decrease in serum levels after resection. It is possible to directly probe the continuous production of amylase by collecting samples from the inflow and outflow vessels of lung cancer. We herein describe an intraoperative measurement in which the amylase level in the pulmonary lobar vein was 3 times greater than that in the superior vena cava which was 6 times greater than the normal range. The venous level of amylase returned to a normal range after resection.
