[Is surgery useful in kidney cancer with lymph node invasion?].
lymph node involvement in renal cell carcinoma is factor of very poor prognosis. In a series of 55 node-positive patients, 33 (60%) had simultaneous renal vein or vena cava invasion and 32 (58.2%) had metastases. Gross lymph node involvement was found in 39 patients (70.9%). Patients without venous invasion or metastasis may have a prolonged survival. In this group, those with microscopic nodal involvement can be cured, as the 10 and 15-year the actuarial survival rate is 54.5% Formal lymphadenectomy might have played a role in these results. Surgery can be performed when vein invasion is present without metastasis, but the prognosis is generally poor. Survival does not seem to be influenced by surgery when metastasis is present, regardless of the vein status.
