Smaller Renal Tumors Predict Longer Surgical Wait Times
Patients whose surgical wait time was 3 months or more versus less than 3 months had 10-fold increased odds of having a smaller tumor.
Surgical wait times for patients with renal masses are longer for those with smaller tumors, study findings presented at the Canadian Urological Association 2016 annual meeting in Vancouver suggest.
In a retrospective study of 350 patients who had surgery for renal masses, Simon Ouellet, MD, and colleagues at Université de Sherbrooke in Quebec, 180 had a surgical wait time of less than 3 months and 170 had a surgical wait time of 3 months or more. The groups were similar with respect to age, sex, the distance from hospital to home, smoking status, body mass index, and the presence of hypertension and diabetes.
Compared with patients who had a surgical wait time of less than 3 months, those with a surgical wait time of 3 months or more had significantly smaller tumors radiologically (4.1 vs 6.9 cm) and a significantly smaller proportion of T2 stage or higher tumors (16% vs 54%).
In multivariate analysis, patients with a surgical wait time of 3 months or more had 10-fold and 2.9-fold increased odds of having a smaller tumor and diabetes, respectively, and 6.6-fold and 11-fold increased odds of undergoing additional investigations with magnetic resonance imaging and renal biopsy, respectively.
