Abstract

INTRODUCTION:

The study objectives were to assess the effect of age, to evaluate the impact of smoking, and to determine the effect of rural residence on tumor characteristics, treatment modalities, and outcomes for Kentucky's endometrial cancer patients.

METHODS:

The Kentucky Cancer Registry identified Kentucky residents diagnosed with endometrial cancer from 1995 to 2002. Data abstracted included demographics, tumor characteristics, treatment, and recurrence/survival status.

RESULTS:

Three thousand five hundred and sixty-two women were diagnosed with endometrial cancer. Mean age at diagnosis decreased significantly (P=0.0388) over the 7-year period. Smokers had higher grade, stage, and worse outcomes. Rural women more often lacked commercial insurance, underwent less comprehensive surgical evaluation, and had less multimodality treatment. Increasing age (P<0.0001), positive or unknown smoking status (P=0.0003), black race (P<0.0001), no commercial insurance (P<0.0001), increasing grade or advanced stage (P<0.0001), small size of treating hospital (P<0.0001), and unknown nodal status (P<0.0001) were negatively associated with disease-specific survival. Lymph node sampling was performed in only 38.6% of women. On multivariate analysis, age (RR 1.38 for 10 year increments; P<0.0001), smoking (RR 1.38; P=0.008), no commercial insurance or Medicaid (RR 1.87; P=0.0007), rural residence (RR 0.77; P=0.011), advanced stage and grade (RR 7.96, 3.96; P<0.0001), and no nodal evaluation or unknown nodal status (RR 2.32, 2.51; P<0.0001) significantly effected disease-specific survival.

CONCLUSIONS:

Our data support a trend toward a younger age for endometrial cancer diagnosis, confirm the adverse impact of smoking and socioeconomic factors, and demonstrate an association between incomplete surgical staging and decreased survival.
