Prognostic role of tumour multifocality in renal cell carcinoma.

2012

Study Type - Therapy (multi-centre cohort) Level of Evidence3b What's known on the subject? and What does the study add? In RCC about 5% of the patients presented multifocal disease. Prevalence of tumour multifocality was associated with a higher percentage of symptomatic RCC, higher pathological TNM stages, higher tumour grade and higher prevalence of tumour necrosis. Although in univariable analysis multifocal tumours had lower probability of CSS, tumour multifocality did not retain an independent predictive role in multivariable analysis. Patient age at surgery, gender, mode of presentation, pathological N stage and presence of metastases were independent predictors of CSS in multivariab…
