We report two cases of local recurrence of renal cell carcinoma, which invaded the gastrointestinal tract. The intervals to local recurrence after primary nephrectomies were 5 and 13 years. Both cases developed massive gastrointestinal bleeding. Blood transfusions and arterial embolization were performed; however, continuous melena prevented improvement in their general condition. Although distant metastases were observed in both cases, tumor resections combined with intestine invasion were performed. Although this surgical approach does not significantly improve the prognosis, even in patients who have remaining metastatic lesions, it may provide palliation and improve the quality of survival.
