Through clinicopathological features comparison, we noticed that there was no significant difference in age, sex ratio, tumor size, treatment (partial/radical nephrectomy ratio), WHO/ISUP grade and pathological stage between the two groups of cases, which further supports the homologous relationship between MCRN-LMP and ccRCC with cystic component similar to MCRN-LMP. The gene discussed is PDLIM7; the disease is nonpapillary renal cell carcinoma.
