Abstract:
Renal metastases of osteogenic sarcoma are unusual clinical occurrence and cases of osteogenic sarcoma treated by nephrectomy for renal metastases have been rarely reported. We report a 19-year-old male who was successfully treated by left nephrectomy for a metastatic tumor of osteogenic sarcoma from the right femur. In 1989 above-knee amputation was performed and the initial relapse with right pulmonary metastasis was treated by right upper lobectomy in 1991. In February 1992 he developed left renal and left pulmonary metastasis, hence left nephrectomy and left upper lobectomy were performed. Metastases of osteogenic sarcoma to the organs other than the lung and bone will increase because of the improvement of diagnostic modalities. Our study suggests that a bone scan is useful for routine follow-up of patients with osteogenic sarcoma and that resection of the metastatic lesion can improve these patients' quality of life.
Insights
This case report details the successful surgical treatment of a rare renal metastasis from osteogenic sarcoma. Resection of metastatic lesions can improve quality of life for patients with osteogenic sarcoma.
Area of Science:
- Oncology
- Surgical Oncology
- Medical Imaging
Background:
- Osteogenic sarcoma, a primary bone cancer, rarely metastasizes to the kidney.
- Surgical intervention for renal metastases of osteogenic sarcoma is infrequently documented.
Observation:
- A 19-year-old male with a history of osteogenic sarcoma presented with left renal and pulmonary metastases.
- The patient had previously undergone amputation and lung metastasectomy for recurrent disease.
Findings:
- Successful left nephrectomy was performed for the renal metastasis.
- The patient also underwent a left upper lobectomy for pulmonary metastasis.
Implications:
- This case highlights the possibility of renal osteogenic sarcoma metastasis and the efficacy of surgical resection.
- Routine bone scans are recommended for monitoring osteogenic sarcoma patients for metastatic disease.
- Surgical removal of metastatic lesions can enhance patient quality of life.
