Multilocular Cystic Renal Cell Carcinoma: Pathological T Staging Makes No Difference to Favorable Outcomes and Should be Reclassified

Multilocular cystic renal cell carcinoma has an excellent prognosis, which remains unchanged regardless of tumor size or pathological T stage. This suggests a strong case for nephron and adrenal sparing surgery when indicated, and nonsurgical management when feasible. Since postoperative followup protocols are dictated by staging, we propose that for this entity pathological T staging should be abandoned or reassigned as pT1c to guide clinicians.
