TI  - CT-estimated volume of Wilms tumor can predict weight.
PG  - 311-3
AB  - Wilms tumor weight was used to recruit patients in a recent National Wilms Tumor 
      Study (NWTS) group trial. The authors hypothesized that a simple calculation of 
      tumor volume based on a preoperative CT scan could predict tumor weight. The 
      authors reviewed charts and CT images of patients with Wilms tumors who were 
      treated at their institution between 1985 and 2002. Tumor volume was calculated 
      as: V = 1/6pi x d (long axis) x d (short axis) x d (craniocaudal). Weight and 
      calculated tumor volume were correlated using linear regression. Complete data of 
      tumor weight and volume could be determined in 25 of the 49 patients. These were 
      highly correlated (Spearman R = 0.97). Wilms tumor weight can be predicted based 
      on a simple estimate of tumor volume on a preoperative CT scan. CT-estimated 
      volume may replace weight as a prognostic factor and in guiding management.
