To facilitate the regression of extra renal disease in response to sys
temic therapy, cytoreductive surgery has been advocated as step 1 in t
he treatment of stage IV renal cell carcinoma. To determine the effect
of surgery on subsequent clinical course, we reviewed the treatment r
ecords of 30 patients with known stage TV carcinoma of the kidney who
underwent nephrectomy or additional procedures in preparation for syst
emic therapy. Of 30 patients only 7 (23%) underwent systemic therapy p
ostoperatively. Progression of the disease, surgical morbidity and mor
tality were the factors preventing 77% of our patients from continuing
with treatment. Since regression of extra renal lesions is the goal o
f systemic therapy, our data suggest that nephrectomy and most other c
ytoreductive operations in preparation for systemic therapy are not ef
ficient treatment strategies.
