Bone resorption predicts for skeletal complications in metastatic bone disease.

Brown JE, Thomson CS, Ellis SP, Gutcher SA, Purohit OP, Coleman RE - Br. J. Cancer (2003)

Bottom Line: All skeletal-related events, plus hospital admissions for bone pain and death during the period of observation, were recorded.Data were available for 121 patients over the first 3-month period of monitoring (0-3 months) and 95 patients over the second 3-month period (4-6 months).In a multivariate logistic regression model, Ntx was highly predictive for events/death.

ABSTRACT
Relationships between the rate of bone resorption (measured by urinary N-telopeptide (Ntx) excretion) and a range of skeletal complications have been evaluated in patients with metastatic bone disease. A total of 121 patients had monthly measurements of Ntx during treatment with bisphosphonates. All skeletal-related events, plus hospital admissions for bone pain and death during the period of observation, were recorded. Data were available for 121 patients over the first 3-month period of monitoring (0-3 months) and 95 patients over the second 3-month period (4-6 months). N-telopeptide levels were correlated with the number of skeletal-related events and/or death (r=0.62, P<0.001 for 0-3 months and r=0.46, P<0.001 for 4-6 months, respectively). Patients with baseline Ntx values > or =100 nmol mmol(-1) creatinine (representing clearly accelerated bone resorption) were 19.48 times (95% CI 7.55, 50.22) more likely to experience a skeletal-related event/death during the first 3 months than those with Ntx <100 (P<0.001). In a multivariate logistic regression model, Ntx was highly predictive for events/death. This study is the first to indicate a strong correlation between the rate of bone resorption and the frequency of skeletal complications in metastatic bone disease. N-telopeptide appears useful in the prediction of patients most likely to experience skeletal complications and thus benefit from bisphosphonate treatment.

Mentions: The table shows the median of the Ntx value that was recorded in the month prior to the event, as well as minimum and maximum values of Ntx for each type of event. Note that these counts are not mutually exclusive as several patients had more than one type of event during the time period 0–6 months. The analysis includes the 111 patients who remained on study or died during the first 6 months.
