[Renal cancers and caval thrombus, prognostic study. Apropos of 25 cases].
Of the 235 renal cancers treated between 1975 and 1984, twenty five cases were complicated by thrombus of the vena cava. Analysis by Kaplan-Meier's method shows a satisfactory survival rate for isolated thrombus of the vena cava (80 per cent at two years, and 45 per cent at five years). But associated lesions to the perirenal fat or lymph nodes considerably diminishes the survival rate, so that the overall survival rate in this series was only 37 per cent at two years and 20 per cent at five years. 57 per cent of the patients who seemed free of distant metastases during the preoperative investigations, nonetheless died within two years postoperatively, from a lung, liver or bone metastasis. CT scan at present allows diagnosis of renal cancer and assessment of the extension to the fatty capsule and the vena cava. It is to be hoped that nuclear spin electronic resonance will provide a better assessment of the prognostic factors, and, in particular, the lymph node extension.
