Acquired renal cystic disease complicated with renal cell carcinoma 11 case reports / 中华泌尿外科杂志

ABSTRACT

Objective To discuss the diagnosis and treatment of acquired cystic kidney disease complicated by kidney cancer. Methods Clinical data of 11 patients with acquired cystic kidney disease complicated by kidney cancer were analyzed retrospectively. Eight patients were male and three were female. The mean age was 55 years old (range 37 to 68). The time of hemodialysis ranged from 2.8 to 7. 4 years, mean 4. 8 years. Results Follow-up ranged from 17- 83 months, mean 55 months. One patient died of cardiovascular disease. Lung metastasis was detected in one patient two years after surgery. Seven patients survived free of tumor recurrence and there was no follow-up on one patient. Conclusions Increased incidence of cancer was observed in patients with end-stage renal disease who have undergone long-term dialysis. In particular, renal cell carcinoma (RCC) showed an excess incidence in ACKD patients. RCC showed an increased prevalence compared with the general population. Patients with predialysis azotemia or a dialysis duration of longer than 3 years should be screened for ACKD. Sonegraphy or CT scanning are useful for early diagnosis of ACKD. We should pay close attention to complications, including ACKD malignant tendency, in patients who have been taking long-term dialysis and positive therapy.
