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.
