二次电切应用于T_1期膀胱癌,可以纠正首次电切的错误分期、清除残留肿瘤组织,而且减少膀胱肿瘤的复发和进展。T_1期膀胱癌二次电切的阳性率与首次电切时的肿瘤特点(肿瘤分级、肿瘤大小、肿瘤数量)相关。T_1期膀胱癌二次电切阳性发现(首次电切的肿瘤残留)不利于预后,分期高的预后差。需要根据二次电切时不同的病理分期制定不同的治疗策略,对于T_0、T_a、T_(is)期需行bacillus Calmette-Guérin(BCG)灌注,T_1期尽早实施膀胱全切可能会获益,T_2期及以上应积极实施膀胱全切。
Secondary electrosurgery applied to T_1 bladder cancer can correct the first staging error staging, remove residual tumor tissue, and reduce the recurrence and progression of bladder cancer. The positive rate of T 2 resection was related to the characteristics of the tumor at the time of initial resection (tumor grade, tumor size, number of tumors). T_1 bladder resection positive results (first resection of tumor residues) is not conducive to the prognosis, poor prognosis of high staging. Different strategies need to be made according to the different pathological staging of secondary resection. Perfusion of Bacillus Calmette-Guérin (BCG) is required for T_0, T_a, and T_ (is), and full bladder resection may be beneficial as early as T_1. T_2 period and above should be actively implemented full bladder resection.
