The prevalence of bilateral involvement is higher in individuals with genetic predisposition syndromes than in those without predisposition syndromes. For example, in 545 cases of bilateral Wilms tumors, bona fide pathogenic germline variants were found in 22% of patients. [ 124] The most common predisposition variants are mutations of WT1 and 11p15 loss of imprinting. [ 22, 72]
Where does Wilms tumor occur?
Wilms tumor may arise during embryogenesis on the background of an otherwise genomically normal kidney, or it may arise from nongermline somatic genetic precursor lesions residing in histologically and functionally normal kidney tissue.

Management of lung metastasis
Patients with negative findings on chest radiography and positive findings on CT scanning of the lungs require tissue diagnosis of the lung nodules because several conditions (eg, histoplasmosis, atelectasis, pseudotumor, intrapulmonary lymph node, pneumonia) can mimic pulmonary metastases.
Management of bilateral Wilms tumor
One report of patients with bilateral Wilms tumor treated according to the National Wilms Tumor Study-4 demonstrated that preservation of renal parenchyma is possible following initial preoperative chemotherapy.
Additional treatment considerations
Whether patients younger than age 6 months who have stage III disease should receive radiation therapy is controversial. In the NWTS-5 protocol, physicians were required to call an NWTS-5 radiation oncologist to discuss guidelines.
Activity
No precautions regarding activity are advised, although the patient and his or her parents should be aware that the patient will have only 1 kidney after therapy. Activities that carry an inherent risk of kidney injury, such as boxing and hockey, should be avoided.
