Abstract

Purpose: To determine whether adding 2 years of androgen-deprivation therapy (ADT) improved outcome for patients electively treated with ADT before and during radiation therapy (RT). Patients and Methods: Prostate cancer patients with T2c-T4 prostate cancer with no extra pelvic lymph node involvement and prostate-specific antigen (PSA) less than 150 ng/mL were included. All patients received 4 months of goserelin and flutamide before and during RT. They were randomized to no further ADT (short-term ADT [STAD] + RT) or 24 months of goserelin (long-term ADT [LTAD] + RT). A total of 1,554 patients were entered. RT was 45 Gy to the pelvic nodes and 65 to 70 Gy to the prostate. Median follow-up of all survival patients is 11.31 and 11.27 years for the two arms. Results: At 10 years, the LTAD + RT group showed significant improvement over the STAD + RT group for all end points except overall survival: disease-free survival (13.2% v 22.5%; P < .0001), disease-specific survival (83.9% v 88.7%; P = .0042), local progression (22.2% v 12.3%; P < .0001), distant metastasis (22.8% v 14.8%; P < .0001), biochemical failure (68.1% v 51.9%; P ≤ .0001), and overall survival (51.6% v 53.9%, P = .36). One subgroup analyzed consisted of all cancers with a Gleason score of 8 to 10 cancers. An overall survival difference was observed (31.9% v 45.1%; P = .0061), as well as in all other end points herein. Conclusion: LTAD as delivered in this study for the treatment of locally advanced prostate cancer is superior to STAD for all end points except survival. A survival advantage for LTAD + RT in the treatment of locally advanced tumors with a Gleason score of 8 to 10 suggests that this should be the standard of treatment for these high-risk patients.

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.
