Analysis Of Long-term Curative Effect Of Radical Nephrectomy

Objective To study the factors which affect the prognosis of radical nephrectomy.Methods 348 cases of renal cell carcinoma treated with "Radical Nephrectomy" from Jan. 1987 to Dec.2003 were reviewed. All the data were input to Excel database after they were encoded, and then read by SPSS 12.0 statistic software. The cumulative survival rates were calculated by the life-table method. We assess the impact of multiple covariates in survival time with Cox Regression model. Statistical analysis were done with the SPSS 12.0 statistic software. All tests were performed at the 0.05 level of significances.Results The pathological results showed that 256 cases were clear cell carcinoma, 41 cases being granular cell carcinoma, 28 cases being complex of the above two varieties, and the others were 23 cases. 193 cases being T₁N₀M₀, 114 cases being T₂N₀M₀, 4 cases being T₂N₁M₀, 3 cases being T3N0M0, 9 cases being T₃N₁M₀, 3 cases being T₃N₂M₀ 22 cases being T₃N₀M₁. 220 cases have been followed up. The 1 year survival rate was 84.47±2.45%, The 3 years survival rate was 73.26±3.28%, The 5 years survival rate was 65.21±4.29%, The 10 years survival rate was 55.18±7.47%.Condutions "Sex", "vena cava", "TNM", "Robson" and "assistant treatment" were significant in statistics(P<0.05); "Age", "symptom", "course of diseases", "left or right side", "medical diseases", "surgical route" and "surgical manner" had no meaning(P>0.05).
