The goal of this study was to identify risk factors in patients with node-positive stage IB, IIA, and IIB cervical carcinoma after radical hysterectomy with pelvic lymph node dissection and postoperative irradiation.
Two hundred forty-two patients with FIGO stage IB, IIA, and IIB cervical carcinoma underwent radical hysterectomy with pelvic lymph node dissection; pathological analysis of the surgical specimen showed positive lymph nodes in 59 patients. These 59 patients were further treated with postoperative radiotherapy. Eighteen patients were in stage IB, 4 in stage IIA, and 37 in stage IIB. Histological tumor type, tumor size, lymph-vascular space invasion, parametrium infiltration, number of positive nodes, and involvement of common iliac nodes were assessed for correlation with cancer recurrence.
When all these variables were assessed in the Cox proportional regression analysis, parametrium infiltration (P = 0. 0199) and number of positive nodes (two or more nodes) (P = 0.0483) revealed the factor correlating significantly with disease-specific survival. Based on these two factors, node-positive patients could be divided into low-risk (n = 11), intermediate-risk (n = 29), and high-risk (n = 19) groups. The 5-year disease-specific survival for the low-risk group was 100% which was significantly better than the 39.1% for the high-risk group (P = 0.0012).
For patients in the high-risk group, it may be worthwhile to consider new strategies to improve survival.
本研究的目的是确定在接受根治性子宫切除术加盆腔淋巴结清扫及术后放疗的IB、IIA和IIB期淋巴结阳性宫颈癌患者中的危险因素。
242例FIGO分期为IB、IIA和IIB期的宫颈癌患者接受了根治性子宫切除术加盆腔淋巴结清扫;手术标本的病理分析显示59例患者有淋巴结阳性。这59例患者进一步接受了术后放疗。其中18例为IB期,4例为IIA期,37例为IIB期。评估组织学肿瘤类型、肿瘤大小、淋巴血管间隙浸润、宫旁浸润、阳性淋巴结数量及髂总淋巴结受累情况与癌症复发的相关性。
在Cox比例回归分析中评估所有这些变量时,宫旁浸润(P = 0.0199)和阳性淋巴结数量(两个或更多淋巴结)(P = 0.0483)显示与疾病特异性生存显著相关。基于这两个因素,淋巴结阳性患者可分为低风险组(n = 11)、中风险组(n = 29)和高风险组(n = 19)。低风险组的5年疾病特异性生存率为100%,显著高于高风险组的39.1%(P = 0.0012)。
对于高风险组患者,考虑新的策略以提高生存率可能是值得的。
