title: [Renal cancer with bone metastasis as initial symptom].
abstract: With a progress of image diagnosis method asymptomatic renal cancers have much chance to be disclosed, but renal carcinoma of which symptoms were caused by metastatic lesion are discovered as an initial symptom has not been decreased. In this paper we reported additional 4 patients who visited our hospital with an initial symptom of metastatic bone pain and were diagnosed that the primary lesion was the kidneys. We further conducted a follow-up study on 4 patients reported previously and discussed on renal cancer with bone metastasis as the initial symptom. Case 1 was a 51-year-old man with lumbar metastasis, case 2 was a 34-year-old woman with vertebral metastasis, case 3 was a 77-year-old man with femur metastasis and case 4 was a 65-year-old woman with femur metastasis. In three of the 4 patients except for case 1, extirpations of the primary lesions were performed. Case 3 and 4 received internal fixation for metastatic lesion in bone. In occasionally four cases, the prognosis was relatively favorable even in advanced renal carcinoma with bone metastasis, so surgical procedures should be made positively for relief of pain in metastatic lesion, maintenance of function and prevention of bone fracture.
