[Tumor cell separation by cell saver and membrane filter passage].

Abstract

Definite suspensions of malignant cells from three human tumor cells lines (bladder, prostate and renal cell carcinom) were passed through a cell saver (Althin Mediplast) and a leucozyte removal filter (PALL RC 100) under standard conditions. The examination of the solutions did not detect any malignant cells at all. If investigations with malignant cells in the blood will confirm these results, the use of intraoperative autotransfusion in urological tumor surgery would be possible.
