Zusammenfassung:Objective—To determine whether a preoperative imaging protocol relying predominantly on a chest X‐ray film (CXR) and ultrasound in patients with Wilms' tumor is adequate for patient management and to determine the frequency more sophisticated imaging, in particular, computed tomography (CT), is required. Design and setting—Historical cohort study at a tertiary pediatric hospital. Subjects—60 consecutive patients with Wilms' tumor treated at our institution between 1980 and 1990. Main outcome measure—The preoperative imaging was recorded and 2‐ and 4‐year survival were compared with the National Wilms' Tumor Study. Results—100% of patients had a preoperative CXR, 95% abdominal ultrasound, 5% abdominal CT, 13% chest CT, 47% abdominal X‐ray, 2% aortography, 5% cavography, and 35% intravenous urography. The overall 2‐ and 4‐year survivals of 92% and 90%, respectively, did not statistically differ from the National Wilms' Tumor Study 2‐ and 4‐year survivals of 94% and 91%. Conclusions—A preoperative imaging protocol relying predominantly on a CXR and abdominal ultrasound does not reduce survival. Other more sophisticated imaging, in particular, CT, is not required in the majority of cases and is warranted only when a CXR or ultrasound is unable to resolve relevant management problems. © 1995 Wiley‐Liss, Inc.
