[A study on the relationship between pathologic morphology and clinical prognosis of renal cell carcinoma]

One hundred and six cases of renal cell carcinoma (RCC) were studied with an objective to investigate the effects of clinical stages, histological patterns (grading), cell types, nuclear grading and tumor sizes on the postoperative survival time of the patients. The results showed that there were no statistical differences in the postoperative survival time among different histological patterns and among different cellular types, such as clear cell, granular cell and mixed cell. But those with either diffuse sarcomatoid pattern or undifferentiated cell type had poor prognosis. The patients with tumor size greater than 10 cm in diameter had poor prognosis. The prognosis-deciding factors for RCC patients were the clinical staging and nuclear grading. We suggest that the nuclear grading of RCC be noted in every pathological report, so as to provide reference for clinical evaluation of the prognosis and further treatment.
