The objective of the study was to analyze the outcomes of patients with renal cell carcinoma (RCC) arising in end-stage renal disease (ESRD) over a 40-year span.
We retrospectively evaluated data of patients with ESRD-RCC diagnosed between 1979 and 2020 at two institutions. We assessed changes in stage, surgical approaches, and cancer-specific survival (CSS) following nephrectomy according to era between ESRD-RCC and sporadic RCC. Furthermore, perioperative outcomes in patients with ESRD-RCC were compared between laparoscopic and open surgery.
Patients with ESRD-RCC (n = 549) were diagnosed at an earlier stage (p = 0.0276), and the ratio of laparoscopic nephrectomy was increased (p < 0.0001) according to eras. Since 2000 (i.e., after implementation of laparoscopic nephrectomy), patients with ESRD-RCC (n = 305) had significantly shorter CSS (p = 0.0063) after nephrectomy than sporadic RCC (n = 2732). After adjustment by multivariate analysis and propensity score matching, ESRD status was independently associated with shorter CSS (p = 0.0055 and p = 0.0473, respectively). Improved CSS in sporadic RCC (p < 0.0001), but not ESRD-RCC (p = 0.904), according to era contributed to this difference. Laparoscopic nephrectomy showed favorable outcomes, including shorter surgery time, lower estimated bleeding volumes, transfusion rates, and readmission rates, and shorter postoperative hospitalization than open nephrectomy (p < 0.05).
Advances in diagnostic and treatment modalities potentially enable early diagnosis and minimally invasive surgery for patients with ESRD-RCC. As ESRD-RCC may not present indolently, careful post-operative monitoring is needed.
