Current Clinical Trials

When diagnosed in the first 7 months of life, the 5 year event-free survival and overall survival rates are 94% and 96%, respectively.[1]

A prospective clinical trial that enrolled 50 patients confirmed that complete surgical resection, which includes the entire capsule, is adequate therapy for most patients with mesoblastic nephroma.[2] In this study, only two of 50 patients died. Patients were at increased risk for local and eventually metastatic recurrence if there was stage III (incomplete resection and/or histologically positive resection margin), cellular subtype, and aged 3 months or older at diagnosis. Because of the small numbers of patients and the overlapping incidence of these characteristics (five of 50 patients), the significance of the individual characteristics could not be discriminated. Adjuvant chemotherapy has been recommended for patients who share these three characteristics, though the benefit of adjuvant therapy will remain unproven with such a low incidence of disease.

Check for U.S. clinical trials from NCI's PDQ Cancer Clinical Trials Registry that are now accepting patients with congenital mesoblastic nephroma ¹. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site ².
