BACKGROUND: Several nomograms were developed for predicting the potential recurrence and cancer death risk in renal cell carcinoma patients. The combination of TNM classification and appropriately selected clinical classifiers allows for the creation of simple and effective risk calculators.
MATERIAL AND METHODS: There were 230 patients with renal cell cancer enrolled in this study. Basic parameters of blood count, serum creatinine and sodium concentrations, and histopathological features of the tumors were analyzed. A determination of whether any of the tested parameters could be used to assess the prognosis of kidney cancer was performed.
RESULTS: When the platelet cell count (PLT) increased by 10 thousand/µL, the risk of metastasis was higher by 5%, and cancer recurrence and death by 10%. A low-risk recurrence group was identified: T1b, PLT <230, Na of 140.6 mmol/L. A high-risk recurrence group was identified: T3a, PLT >280, Na of 143.4 mmol/L. A low-risk cancer specific mortality group was identified: T2a, absence of metastases, preoperative creatinine level of 85.6 µmol/L, and the value of PLT 227.0×103. A high-risk cancer specific mortality group was identified: T3a, the presence of metastases in the lungs (M), serum creatinine before treatment level of 97.9 µmol/L, and the value of PLT 299.5×10³.
CONCLUSIONS: Preoperative PLT, serum sodium, and tumor staging were independent risk factors for local recurrence. Blood PLT, serum sodium, creatinine, and tumor staging were useful indicators for estimating 5-year cancer specific survival.
