Abstract:
Ewing sarcoma arising from kidney has been considered poor prognosis. Surgical extirpation combined with chemotherapy (C/T), and/or radiotherapy (R/T) are the mainstay of treatment. We report two cases at Kaohsiung Veterans General Hospital. We discuss their treatment and outcome to guess which choice is better.
The 14-year-old girl with no congenital abnormality suffered from a left huge renal mass. Renal cell carcinoma was initially suspected and radical nephrectomy was performed. But pathology showed the primitive neuroectodermal tumor (Ewing sarcoma), with pancreas tail invasion (noted by intra- operative Frozen). She received adjuvant C/T ( total 48 times). Besides, R/T with 45Gy was also performed. Another one was a healthy 17-year-old boy who also had a left large renal mass with suspected lung metastasis and IVC thombus. Biopsy was firstly done and primitive neuroectodermal tumor was diagnosed. Neo-adjuvant C/T were given. Then, radical nephrectomy, with IVC thrombectomy were performed and adjuvant C/T (total 51 times ) + R/T (chest and abdomen )with 54Gy.
The girl has followed 48 months till now. Lung metastases (left upper and left lower) were found in 6 months later after adjuvant C/T completed. She received wedge resection of lung metastases, radiotherapy and relapse C/T. Interestingly, the boy’s pre-operative computed tomography showed the tumor burden decreased. He has followed 30 months till now. No obvious relapse notes after C/T completed 10 months earlier.
According to our experience, neo-adjuvant C/T and then followed locally control combine adjuvant C/T and R/T is better. Pediatric renal mass is difficult to diagnose. If biopsy is used to survey pathohistology initially, neo-adjuvant C/T may be feasible. But more follow-up time and cases must be needed to evaluate outcome.
