Influence of treatment center and hospital volume on survival for locally advanced cervical cancer.

ABSTRACT:

Objective

Procedural volume is associated with outcomes for many surgical interventions. Little is known about the association between volume and outcomes of radiation. We examined the association between treatment center and hospital volume and outcomes for women with locally advanced cervical cancer treated with radiation.

Methods

Women with stage IIB-IVA cervical cancer treated with primary radiation from 1998 to 2011 and recorded in the National Cancer Database were examined. Hospital volume was estimated as the mean annualized volume, while center-specific effects on care were examined using a hospital-specific random effect. Multivariable regression models adjusted for metrics of treatment quality were used to estimate survival.

Results

20,766 patients treated a
