English to Chinese: Risk of tumour progression after radical cystectomy | |
Source text - English The risk of tumour progression after radical cystectomy strongly depends on the histopathological tumour stage. The risk of tumour progression increases stepwise, from 5% in patients undergoing cystectomy for pT1 G3 tumours (1,2) to almost 100% in patients with pN2 disease (3,4).
Progression risk is highest within the first 24 months following cystectomy, declines from months 24 to 36 and is relatively low after month 36 (3). Tumour progression may occur locally in the true pelvis, in regional or juxtaregional lymph nodes or as distant metastases. Furthermore, urothelial remnants in the upper urinary tract and/or urethra need to be checked for intraluminal tumour recurrences. The total risk of intraluminal recurrences may range from 5-15% with about 50% of cases occurring within 12 months. The risk of new intraluminal tumour formation does not decrease with time (5-7). | Translation - Chinese 膀胱根除術後腫瘤進展的風險
膀胱根除術術後腫瘤進展的風險和病理性腫瘤分期有高度的相關性並隨之階段性的增加;由在原發性腫瘤第三級接受除膀胱根除術的5%復發率(1,2)到腫瘤淋巴腺蔓延第二級接受手術後將近100%復發率(3,4)。
腫瘤進展癌化的風險在術後的24個月最高,在術後的24至36個月中慢慢降低,術後36個月後腫瘤再進展的風險則相對的非常低(3)。腫瘤的進展復發可能局部發生在眞骨盆腔、鄰近或周圍淋巴腺、甚至遠處的淋巴轉移;此外必須檢查上輸尿管部剩餘的泌尿系統和尿道管道內腫瘤再生的可能性。總體說來管道內腫瘤再發生的風險在5-15%之間,其中大約50%的病例發生在術後的12個月內(5-7);管道內腫瘤新生的風險則不會隨著時間降低。
