Recent studies point out the important role of the immune system in the progression of renal cell carcinoma (RCC). Numerous articles show the value of intratumoral lymphocytic infiltration. However, there are few studies on the importance of peritumoral lymphocytic infiltrate, and the results are contradictory. Therefore, the study of the local immune response, which is represented by peritumoral lymphoid infiltrate, is very significant. The aim of the study was to evaluate the relationship between clinicopathologic parameters and density of lymphoid infiltrate (DLI) in the peritumoral zone (PZ). In addition, the objective was to figure out whether DLI in PZ is a prognostic factor for survival of RCC patients.


Postoperative material from 129 patients with RCC has been studied. The average age of the patients was 57,8 ± 9,7 years. DLI in PZ was evaluated at a 1000x magnification in 5 fields of view using tissue specimens stained with hematoxylin and eosin. Statistical analysis was carried out using the program Statistica 6.1.


We revealed a correlation between DLI and: 1) TNM stage (r = 0,312; p 


Based on our findings, we believe that high DLI in PZ found at RCC patients can be attributed to a negative prognostic marker.
