Extent of lymph node dissection at nephrectomy affects cancer‐specific survival and metastatic progression in specific sub‐categories of patients with renal cell carcinoma (RCC)

Objective To test whether the number of lymph nodes removed affects cancer‐specific survival ( CSS ) or metastatic progression‐free survival ( MPFS ) in different renal cell carcinoma ( RCC ) scenarios. Methods We used C ox regression analyses to analyse the effect of the number of lymph nodes removed on CSS and MPFS in 1983 patients with RCC treated with nephrectomy. To adjust for possible clinical and surgical selection bias, analyses were...
