目前,淋巴结阳性的患者前列腺癌根治术后肿瘤复发的模式是未知的。为了描述肿瘤复发的模式,确定肿瘤进展的预测并研究肿瘤临床复发的部位对肿瘤特异性死亡率的影响,我们分析了1 003例行前列腺癌根治术+扩大盆腔淋巴结清扫术的淋巴结阳性患者。其中生化复发370例,临床复发183例。临床复发定义为生化复发后影像学阳性。依据患者复发的第一个部位进行分组:局部和/或淋巴结(前列腺窝和/或盆腔淋巴结)、腹膜后、骨或内脏。利用多元竞争风
Currently, the pattern of tumor recurrence after radical prostatectomy in lymph node-positive patients is unknown. To characterize the pattern of tumor recurrence, determine the prediction of tumor progression, and investigate the effect of site of tumor recurrence on tumor-specific mortality, we analyzed 1 003 patients who underwent radical prostatectomy plus lymph node dissection with enlarged pelvic lymph node dissection. Among them, there were 370 cases of biochemical recurrence and 183 cases of clinical recurrence. Clinical recurrence was defined as positron emission imaging after biochemical recurrence. Grouping according to the first site of patient recurrence: local and / or lymph node (prostate and / or pelvic lymph nodes), retroperitoneal, bone or internal organs. Use multiple competitive winds
