Long-term Survival of Bladder Cancer Metastatic to Femoral Neck Treated with Chemotherapy, Radiation, and Arthroplasty: A Case Report

Case: A 64-year-old male suffered a pathologic left femoral neck fracture. Biopsy demonstrated metastatic urothelial cancer with a non-muscle invasive bladder cancer primary confirmed by cystoscopy. Patient underwent hemiarthroplasty, chemotherapy, radiation, and eventually, a conversion to total hip arthroplasty. Today, over a decade from initial surgery, the patient remains alive and highly functional. To our knowledge, this is the only report of bone metastatic bladder cancer with over 10-year survival. Conclusion: Bladder cancer metastatic to bone has a 5-year survival rate of 3%. Surgical resection of metastasis with reconstruction may confer a survival benefit in bony oligometastatic bladder cancer.
