Clinical importance of dependent prognostic factors for renal parenchymal carcinoma and a possibility of predicting the treatment outcome.
AIM To determine an influence of dependent predictors (clinical presentation, stage, pH type) on survival of patients suffering from renal carcinoma. METHODS The research included 158 patients who had been treated for carcinoma of renal parenchyma in the period between 1 January 1998 and 31 December 2011. A disease stage was determined according to the guidelines of the American Joint Committee on Cancer (AJCC). Prognostic factors were tested by the Cox regression analysis, and dependent prognostic factors were determined based on significance. RESULTS Patient survival was significantly different in relation to the clinical presentation of the disease (p less than 0.0001). Length of patient survival significantly differs with regard to the clinical stage of the disease (p less than 0.0001). The length of patient survival significantly differs depending on a pathohistological type of cancer (p=0.0027) and after five years it was much longer for patients with the conventional cancer type as compared with the chromophobe type, 80.3% vs. 61.5%, respectively. The total survival rate of patients with renal parenchymal cancer is 81.2% after one year, 77.6% after 5 years and 70.4% after 10 years. CONCLUSION The manner of detection, clinical stage and pathohistological type of the disease did not meet requirements for independent predictors. Success of the therapeutic treatment depends on the manner of the renal cell carcinoma presentation, pathohistological type and tumor stage.
