The Prognostic Value of Modal Deoxyribonucleic Acid in Low Grade, Low Stage Untreated Prostate Cancer

Abstract
We selected for a prospective surveillance study 167 patients with untreated grades 1 and 2 prostate cancer. The tumors were classified regarding modal deoxyribonucleic acid value (ploidy) by flow cytometry, cytological grade by transrectal fine needle aspiration biopsy and local tumor stage. Of the patients 146 could be evaluated. Mean followup was 50 months.
