肿瘤大小和分期是评价肾细胞癌预后的重要参数。虽然T_1和T_2期仅通过肿瘤大小来进行病理分期,但由于肿瘤的某些固有特性的存在,肿瘤病理分期可升为T_(3a)而不论其大小。研究者此次研究的目的即是研究肿瘤病理分期对肿瘤的大小和疾病复发的风险之间关系的影响。纳入研究的对象是研究者所在医院2006年至2013年行肾切除术且病理分期确诊为T_1、T_2及T_(3a)的1 809例患者。以复发时间为结果,以肿瘤大小和分期为协变量来构建COX回归模型,肿
Tumor size and stage are important parameters for evaluating the prognosis of renal cell carcinoma. Although the T 1 and T 2 stages are only pathologically staged by the size of the tumor, the pathological staging of the tumor may rise to T 3a regardless of its size, due to the inherent nature of the tumor. The purpose of this study was to examine the impact of tumor pathology on the relationship between tumor size and the risk of disease recurrence. The subjects enrolled were 1,809 patients who underwent nephrectomy and were diagnosed as T_1, T_2 and T_ (3a) in the hospital from 2006 to 2013, respectively. The recurrence time as a result, the tumor size and staging as a covariate to construct COX regression model, swollen
