[Tumor factors influencing the prognosis of renal cell carcinoma].
Fifty six patients, 40 males and 16 females, received radical nephrectomy and were diagnosed to have renal cell carcinoma pathologically at Asahi General Hospital between January, 1972 and September, 1984. The five and ten year survival rates were 44.2 and 35.7% respectively. The cancers were classified according to pTNM category and their cell type and grade were estimated. The relationship between these factors and the patient's prognosis was studied. We recognized a close correlation among pT, cell type and grade, and found that they had a serious influence on prognosis. There was a close correlation between grade and pV, but no relationship between pN, pM and grade. Cases with a positive lymph node or distant metastasis had poor prognosis. Therefore, we suggest the possibility of false negative evaluation of pN and pM, because pN and pM were estimated clinically. Consequently, we believe that the pTNM category is a good classification for evaluation tumor expansion and the prognosis.
