[A CASE OF UNRESECTABLE METASTATIC RENAL CARCINOMA SUCCESSFULLY TREATED BY COMBINED MODALITY THERAPY WITH NIVOLUMAB AND SURGERY].

Abstract

The patient was a 65-year-old male who was referred with right renal mass (8 × 6.7 cm) and swelling of para-aortic lymph nodes in CT in April, 20XX. Additional examinations revealed inferior vena cava invasion, multiple lung metastases and left iliac bone metastasis and he was diagnosed with a renal cell carcinoma (cT4N1M1b). Pazopanib was administered as the first line treatment for an unresectable renal cancer. Nivolumab was then administrated as the 2nd line therapy due to the disease progression evaluated in (late) June, 20XX. However, immediately after the first administration of nivolumab, the patient have a difficulty in walking resulting from low-back pain, and MRI showed multiple lumbar vertebral metastases and L2 compression fracture. He was transferred to another hospital for combined modality therapy including right femoral head replacement and palliative radiotherapy in August, 20XX. Nivolumab was resumed since he had stable disease after his return to our hospital, and a total of 20 cycles of nivolumab treatment was performed. A follow-up CT showed 70% decrease in an initial primary tumor and tumor decrease or disappear in metastatic lung and bone tumors. The primary tumor was considered surgically resectable, and a radical nephrectomy was performed in August 20XX +1. Histopathological examination showed with a marked effect of neoadjuvant therapy and no evidence of viable tumor cells. We report a case of unresectable carcinoma that was successfully treated with nivolumab.
