Purpose
Life expectancy is routinely used as part of the decision-making process in deciding the
value of surgery for the treatment of bone metastases. We sought to investigate the
validity of frequently used indices in the prognostication of survival in patients with
metastatic bone disease.
Methods
The study prospectively assessed 191 patients who underwent surgery for metastatic bone
disease. Diagnostic, staging, nutritional, and hematologic parameters cited to be related to
life expectancy were evaluated. Preoperatively, the surgeon recorded an estimate of
projected life expectancy for each patient. The time until death was recorded.
Results
Kaplan-Meier survival analyses indicated that the survival estimate, primary diagnosis, use of
systemic therapy, Eastern Cooperative Oncology Group (ECOG) performance status, num-
ber of bone metastases, presence of visceral metastases, and serum hemoglobin, albumin,
and lymphocyte counts were significant for predicting survival (P .004). Cox regression
analysis indicated that the independently significant predictors of survival were diagnosis
(P .006), ECOG performance status (P .04), number of bone metastases (P .008),
presence of visceral metastases (P .03), hemoglobin count (P .009), and survival
estimate (P .00005). Diagnosis, ECOG performance status, and visceral metastases
covaried with surgeon survival estimate. Linear regression and receiver-operator character-
istic assessment confirmed that clinician estimation was the most accurate predictor of
survival, followed by hemoglobin count, number of visceral metastases, ECOG performance
status, primary diagnosis, and number of bone metastases. Nevertheless, survival estimate
was accurate in predicting actual survival in only 33 (18%) of 181 patients.
Conclusion
A better means of prognostication is needed. In this article, we present a sliding scale for
this purpose.

INTRODUCTION
Decisions regarding potential surgery for met-
astatic disease require reliable data about
patient survival and quality of life. This inves-
tigation evaluated factors that have been cited
as important correlates to patient post-
operative survival and compared them to sur-
geon preoperative survival estimates.
This information is sought for many
reasons. It helps to set appropriate expecta-
tions for the patient, family, and medical
staff. Data about cost, risk, and quality of life
are often conflicting, but if these data could
be weighed properly, it would help to define
the most appropriate treatment for patients
with metastatic bone disease.
