Acquired Cystic Disease of the Kidney and Renal Cell Carcinoma - part 4

So sánh các đặc điểm mô học của ung thư biểu mô tế bào thận giữa các bệnh nhân chạy thận và dân số nói chung. Ở những bệnh nhân lọc máu, ung thư biểu mô tế bào rõ ràng là ít thường xuyên hơn, và ung thư biểu mô tế bào dạng hạt và ung thư biểu mô tế bào mao mạch thận thường xuyên hơn, | Renal Cell Carcinomas in Dialysis Patients 29 Spindle 3 Chromophobe 1 s Cyst-assodated 7 Dialysis patients n 1O49 Clear 54 Granular 19 General population n 1167 83 Onishi Ĩ Qin Urol 2002 56 665 Hashimoto Y et al Jpn J Ur ol Sui g 2000 13 592 Abe A et a I Jpn J Ur ol 2002 93 371 Kĩu ra H et al Jpn J Urol 2002 93 371 Papillary 17 Fig. 36. Comparison of the histological characteristics of renal cell carcinomas between dialysis patients and the general population. In dialysis patients clear cell carcinoma is less frequent and granular cell carcinoma and papillary renal cell carcinoma are more frequent than in the general population. Papillary renal cell carcinoma is particularly frequent in renal cell carcinoma related to acquired cystic disease of the kidney Table 6. Prevalence of acquired cystic disease of the kidney renal tumors and renal cell carcinoma as reported in the literature Total cases from 25 references examined CT US autopsy Cysts aCdk Renal tumor RCC 1103 Cases 520 Cases 47.1 53 Cases 4.8 17 Cases 1.5 CT computed tomography 3 Prevalence In relation to the prevalence of renal cell carcinoma observed in 1103 dialysis patients as reported in the literature including imaging and pathological diagnoses cysts were observed in 47.1 renal tumors in 4.8 and renal cell carcinomas in 1.5 14 Table 6 . According to the results of my 10-year follow-up data the annual incidence of renal cell carcinoma was 0.4 34 . Based on a questionnaire survey in 2004 it was 0.2 and in a 20-year follow-up study it was 0.3 . This means that the first screening of 100 patients at a dialysis center reveals renal cell carcinoma in 1-2 dialysis patients and further screenings of the same group reveal the disease in 1 patient every 2.5 years thereafter. Acquired renal cysts are observed in about 50 of dialysis patients and since the prevalence of renal cell carcinoma is 1.5 about 3 of the patients with ACDK are 30 Acquired Cystic Disease of the Kidney and Renal Cell Carcinoma expected to .
