  • Title: [Significance of local tumor associated infiltration of mononuclear leukocytes for persistent tumor formations following transurethral resection (TUR) of bladder cancers].
    Author: Flamm J.
    Journal: Z Urol Nephrol; 1985 Feb; 78(2):65-70. PubMed ID: 3993242.
    Abstract:
    In 140 patients with primarily curatively resected tumour of the urinary bladder the inclination to persistence was investigated in relation to the local peritumoural infiltration of leucocytes. 19% of the tumours with cellular infiltration and 33% of the tumours without cellular infiltration showed persistent tumour formations. Altogether 30 (21%) of the 140 tumours were persisting. The following parameters were found in persistent tumour formations: Multifocal tumours have a higher persistence rate than isolated primary tumours. With increasing degree of malignancy (G) the rate of persistence is elevating. It seems that in differentiated transurethral resection (separate resection of the exophyte, the tumour basis, resection of the marginal wall, if necessary, with second look operation) the local depth spreading of the tumour has no influence on the rate of persistence. Tumours without peritumoural infiltration with mononuclear leucocytes show a higher persistence rate than tumours with cellular infiltration, in which case this difference becomes even more significant with advanced tumour formation (T) and degree of malignancy (G).
