TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Aberrant DNA content has been discussed as a potential prognostic feature in prostate cancer.', 'We analyzed the clinical significance of DNA ploidy in combination with prognostic relevant deletions of PTEN and 6q15 in 3,845 prostate cancers.', 'The DNA status was diploid in 67.8%, tetraploid in 25.6%, and aneuploid in 6.8% of tumors, and deletions of PTEN and 6q15 occurred in 17.8% and 20.3% of tumors. Abnormal DNA content and deletions were linked to high Gleason score, advanced tumor stage, and positive nodal stage (P < 0.0001 each). The risk of PSA recurrence increased from diploid to tetraploid and from tetraploid to aneuploid DNA status (P < 0.0001 each). However, 40% of patients with Gleason score ≥4+4 and 55% of patients with PSA recurrence had diploid cancers. This fraction decreased to 21% (Gleason ≥4+4) and 29% (PSA recurrence) if PTEN and/or 6q deletion data were added to ploidy data to identify cancers with an aberrant DNA status. The significance of combining both deletions and ploidy was further demonstrated in a combined recurrence analysis. Presence of deletions increased the risk of PSA recurrence in diploid (P < 0.0001), tetraploid (P < 0.0001), and aneuploid cancers (P = 0.0049), and the combination of ploidy data and deletions provided clinically relevant information beyond the CAPRA-S nomogram. Multivariate modeling including preoperatively and postoperatively available parameters identified the "combined DNA status" as a strong independent predictor of poor patient outcome.'] Does the Combination of DNA Ploidy Status and PTEN/6q15 Deletions provide Strong and Independent Prognostic Information in Prostate Cancer?
