Abstract

BACKGROUND.: For patients with bone metastases, high N‐telopeptide of type I collagen (NTX) levels correlate with increased risks of skeletal‐related events and death. However, the relation between NTX decreases and clinical benefits is unclear. METHODS.: Correlations between NTX normalization during treatment and clinical outcome were retrospectively analyzed in 3 large, phase 3 trials. Urinary NTX levels were measured at baseline and at Month 3 in patients with bone metastases from breast cancer (BC; n = 578), hormone‐refractory prostate cancer (HRPC; n = 472), or nonsmall‐cell lung cancer and other solid tumors (NSCLC/OST; n = 291) who received zoledronic acid or control (pamidronate for BC; placebo for HRPC and NSCLC/OST) for up to 24 months. NTX levels were characterized as normal (N; <64 nmol/mmol creatinine) or elevated (E; ≥64 nmol/mmol creatinine). RESULTS.: After 3 months of zoledronic acid, most N‐group patients maintained normal levels; however, most E‐group patients normalized their NTX levels (BC, 81%; HRPC, 70%; NSCLC/OST, 81%). In contrast, NTX levels normalized with pamidronate in 65% of BC, with placebo in 8% of HRPC, and in 17% of NSCLC/OST E‐group patients. Normalized NTX correlated with improved overall survival versus persistently elevated NTX (significant for zoledronic acid‐treated patients; trend for placebo‐treated patients). Moreover, percentage reductions from baseline NTX levels correlated with benefits regardless of whether patients transitioned from E to N. CONCLUSIONS.: Zoledronic acid normalizes or maintains normal NTX levels in most patients with bone metastases. Normalized NTX within 3 months of treatment, versus persistently elevated NTX, was associated with reduced risks of skeletal complications and death. Cancer 2008. © 2008 American Cancer Society.

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.
