ABSTRACT
PURPOSE:
We evaluated the role of several prognostic factors in predicting death and/or progressive disease in patients with renal cell carcinoma. MATERIALS ANDMETHODS:
Between 2004 and 2010, 227 consecutive patients with renal cell carcinoma underwent radical nephrectomy at our Institute. All histological specimens were examined by the same pathologist. We considered certain histological parameters, including histological subtype, conventional Fuhrman grade, presence of sarcomatoid features, adrenal gland infiltration, invasion of the perinephric fat, vascular embolization, collecting system invasion, presence or absence of tumour necrosis (0%, 1% to 49%, or 50% or greater) and regional lymph node metastasis.RESULTS:
Variables significantly associated with death and/or progressive disease on univariate analysis were histological subtype (p = 0.006), Fuhrman grade (p < 0.0001), tumor necrosis (p = 0.009), perinephric fat invasion (p = 0.002), vascular embolization (p = 0.0002), presence of lymph node involvement (p < 0.002), tumor size (p = 0.0006), TNM stage (p < 0.00001) and presence of metastasis (p < 0.00001). In the multivariable model histological subtype, tumor necrosis, lymph node involvement and presence of metastasis were independent risk factors for disease-free survival (p = 0.011, 0.042, 0.025 and p < 0.0001, respectively).CONCLUSION:
Histological subtype, tumor necrosis, lymph node involvement and presence of metastasis proved to be independent prognostic factors for disease-free survival. Therefore, the presence and rate of tumor necrosis should always be informed by the pathologist and lymphadenectomy should be performed in all patients.
