Prognostic Significance of Positive Surgical Margins in Radical Prostatectomy Specimens

Abstract

PURPOSE: The prognostic significance of positive surgical margins in radical prostatectomy specimens was assessed. MATERIALS AND METHODS: The interval to progression (increasing prostate specific antigen level) was measured in 478 patients by status of the surgical margins. RESULTS: At 5 years, the nonprogression rate was 64% for patients with and 83% for those without positive surgical margins. With a high grade cancer, seminal vesicle invasion or lymph node metastases, positive surgical margins had no effect on prognosis; with extracapsular extension and a Gleason score of 6 or less positive surgical margins were associated with a higher progression rate. CONCLUSIONS: Prognosis was adversely affected by positive surgical margins only in moderately differentiated cancers with extracapsular extension alone. If the cancer is otherwise confined, positive surgical margins are associated with an excellent prognosis unlikely to be improved by adjuvant therapy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
