The cellular DNA content of fine needle aspirates from 300 patients with newly discovered, untreated prostatic carcinomas was measured by flow cytofluorometry. Well-differentiated tumors were mostly diploid or tetraploid aneuploid while poorly differentiated tumors were almost exclusively aneuploid, with a predominance of nontetraploid modal values.(More)
In a randomized study of advanced renal cell carcinoma 60 patients were allocated to treatment with either recombinant interferon alpha-2a or medroxyprogesterone acetate. Correlation between the dose of interferon alpha-2a and plasma-concentration indicated linear kinetics. Survival was similar in the two treatment groups. Only one complete and one partial(More)
In the present study material obtained from prostatic lesions by transrectal aspiration biopsy was subjected to a comparative morphologic and cytophotometric DNA analysis. Based on the morphologic pattern, the clinical material was divided into benign lesions (prostatic hyperplasia), suspected prostatic malignancy and highly, moderately and poorly(More)
Cell material from 100 cases of newly diagnosed bladder tumours was studied with rapid flow cytofluorometric DNA analysis. The degree of ploidy and the percentage of cells in the S-phase characterising the proliferation pattern of the tumours were determined from DNA histograms. The results were related to the tumour categories and to the histopathological(More)
229 patients with Grade 1-2 tumours (WHO), all category Ta or T1 (UICC) and surgically treated, were followed clinically and by flowcytofluorometric DNA-analysis (FCM). The tumours were characterised by their DNA profile. 175 cases were found to be diploid and fifty-four cases showed aneuploidy. The mean follow-up time with continuous FCM analysis was 2.6(More)
Biopsies from bladder tumors of 41 patients were investigated by flow-cytofluorometric DNA analysis and compared with exfoliated cells. The degrees of ploidy and proliferation were determined. Good agreement was found between the degrees of ploidy and proliferation in the biopsies and the exfoliated cell material. Tumors Grade I-II were either euploid or(More)
