Abstract

Purpose: Primary androgen-deprivation therapy (PADT) is often used to treat clinically localized prostate cancer, but its effects on cause-specific and overall mortality have not been established. Given the widespread use of PADT and the potential risks of serious adverse effects, accurate mortality data are needed to inform treatment decisions. Methods: We conducted a retrospective cohort study using comprehensive utilization and cancer registry data from three integrated health plans. All men were newly diagnosed with clinically localized prostate cancer. Men who were diagnosed between 1995 and 2008, were not treated with curative intent therapy, and received follow-up through December 2010 were included in the study (n = 15,170). We examined all-cause and prostate cancer-specific mortality as our main outcomes. We used Cox proportional hazards models with and without propensity score analysis. Results: Overall, PADT was associated with neither a risk of all-cause mortality (hazard ratio [HR], 1.04; 95% CI, 0.97 to 1.11) nor prostate-cancer–specific mortality (HR, 1.03; 95% CI, 0.89 to 1.19) after adjusting for all sociodemographic and clinical characteristics. PADT was associated with decreased risk of all-cause mortality but not prostate-cancer–specific mortality. PADT was associated with decreased risk of all-cause mortality only among the subgroup of men with a high risk of cancer progression (HR, 0.88; 95% CI, 0.78 to 0.97). Conclusion: We found no mortality benefit from PADT compared with no PADT for most men with clinically localized prostate cancer who did not receive curative intent therapy. Men with higher-risk disease may derive a small clinical benefit from PADT. Our study provides the best available contemporary evidence on the lack of survival benefit from PADT for most men with clinically localized prostate cancer.

    The Discussion addresses primary androgen-deprivation therapy for clinically localized prostate cancer, not preclinical anticancer effects of FBZ. Searches for FBZ, fenbendazole, and anticancer mechanisms found no passage addressing the claim in our copy. (LLM, conf=0.77)

  • Benzimidazoles, including FBZ, exert anticancer effects through several mechanisms, including disruption of microtubule polymerization, induction of apoptosis, cell cycle arrest at G2/M, inhibition of angiogenesis, and interference with glucose and glutamine metabolic pathways.

    “Benzimidazoles, including FBZ, exert anticancer effects through several mechanisms: they disrupt microtubule polymerization, induce apoptosis, arrest the cell cycle at the G2/M phase, inhibit angiogenesis, and interfere with both glucose [3] and probably also glutamine [4] metabolic pathways.”

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.
