Resection of Renal Cell and Prostate Carcinoma Sternum Metastases with Long-Term Follow-Up: A Report of 2 Cases.

INTRODUCTION: Rarely solitary sternum metastases are addressed by resection. Two additional cases are presented as they are interesting because of their long-term follow-up.

CASE PRESENTATION: Case 1: A renal cell carcinoma was treated by transabdominal nephrectomy at age 64. Right iliac bone and sternum metastases were diagnosed 7 months later and treated by internal hemipelvectomy followed by sternum metastasectomy 6 weeks after the internal hemipelvectomy. At 12-year follow-up, the patient appears disease free. Case 2: Prostate cancer was treated by prostatectomy at age 67. A subsequent solitary sternum metastasis was resected 10 years later for persistent PSA-activity despite repeated radiotherapy. The patient remains asymptomatic for 3 years now.

CONCLUSION: Resection of sternum metastases may have curative potential and should be considered in tumours known to be rather resistant to chemo- and/or radiotherapy.
