STAGE-IV RENAL-CELL CARCINOMA

Data from 104 patients with stage IV renal cell carcinoma were evaluat ed to investigate relationships between survival and gender, race, age , tumor size, lung versus bone metastasis, number of metastatic sites and nephrectomy. No statistically significant differences in survival were found beta een gender or racial groups, nor was there a statistic ally significant relationship between survival and patient age. Surviv al tended to decrease as tumor size increased. Survival was worse for patients with multiple metastatic sites compared to those with only 1 metastatic site, and for patients with bone and lung metastases compar ed to those with lung but no bone metastases and bone but no lung meta stases. Although nephrectomy patients appeared to have somewhat better survival rates than those without nephrectomy, this difference was ap parently due to better prognostic factors for nephrectomy patients.
