Pediatric regimens in the treatment of adult-onset, metastatic Wilms tumor: A case report.

The optimal treatment of adult-onset Wilms tumors (WTs) in elderly patients is a debated area, as pediatric protocols are thought to carry unacceptable toxicity. We treated a 62-year-old female with good performance status and Stage IV (T1b N1 M1) favorable histology WT using pediatric adjuvant and salvage chemoradiation protocols. Though she experienced nodal relapse and both adjuvant and salvage treatment were discontinued early due to toxicity, she obtained excellent oncologic outcomes, having remained disease-free for 32 months. We recommend considering pediatric protocols for elderly WT patients with good performance status, anticipating dose reductions and possible early chemotherapy termination.
