title: [Report of two cases of advanced renal cell carcinoma and our experience at Mito Saiseikai General Hospital].
abstract: A tumor thrombus in the vena cava (infrahepatic) was identified in a 70-year-old male with chronic obstructive lung disease, and right nephrectomy and thrombectomy were performed successfully. Therefore, he enjoyed good health for 6 months until he developed bone metastasis in the vertebrae and upper gastrointestinal bleeding. In another case of a 51-year-old male who presented with a mass in the posterior part of the chest; the biopsy specimen of the mass was reported to at least resemble renal-cell carcinoma. Subsequently, he underwent right nephrectomy and thoracotomy to remove the mass. He has since led an uneventful life without tumor recurrence. In our hospital from 1971 to 1980, 9 cases of renal-cell carcinoma have been experienced, including the above 2 cases. Their average age was 49.4 years, with ages ranging from 34 to 70 years. Seven patients presented with gross hematuria, and 2 patients, with flank pain. All 9 cases, all of whom underwent radical nephrectomy, were diagnosed pathologically as having renal cell carcinoma. The right side was involved in 3 cases, and the left, in 6 cases. The upper pole of the kidney was involved in 2 cases the middle in 1 case, and the lower in 5 cases. The mean 5-year survival rate was 69.2% and was closely associated with the tumor stage.
