    Purpose. To evaluate if Wilms tumor histopathology predicts occurrence of pulmonary metastases and the response of lung metastases to neoadjuvant chemotherapy. Methods. Seventy-nine patients under age 16 years were identified with Wilms tumor in 1988 – 2015. All thoracic CT-images before and after neoadjuvant chemotherapy with suspected metastases were re-evaluated. Tumor volumes were measured from CT- or MRI-images (available in 52/79 patients). Tumor samples from both pre-treatment cutting needle biopsies (CNB) and from nephrectomy were re-evaluated (59/79). Results. Pulmonary metastases were found in 14 out of 79 (18%) patients. Patients with pulmonary metastases had larger Wilms tumor volume (903, IQR 807-1215 ml vs. 428, IQR 299-765 ml; p<0.001), and tended to have predominance of blastemal cells in diagnostic CNB (75, QR 50-97% vs. 50, IQR 20-80%; p=0.064) compared to t..
