The routine use of extraperitoneal surgical staging prior to radiation therapy in patients with bulky or locally advanced cervical carcinoma remains controversial.
A review was performed of 266 patients with cervical carcinoma who underwent extraperitoneal pelvic and paraaortic lymphadenectomy prior to receiving radiotherapy. Patients were divided into groups based on their lymph node status. Group A had negative lymph nodes; Group B had resected, microscopic lymph node metastases; Group C had macroscopically positive lymph nodes that were resectable at the time of surgery; and Group D had unresectable lymph nodes. All patients received standard radiotherapy utilizing external beam and brachy-therapy. Patients with lymph node metastases received extended field irradiation. Survival probabilities were computed by the Kaplan-Meier product limits method with statistical significance determined by the Mantel-Cox log rank test.
Lymph node metastases were detected in 50% of patients. Five- and 10-year disease free survival rates were similar for all patients in Groups B and C. All patients in Group D recurred. There was a 10.5% incidence of severe radiation-related morbidity and a 1.1% incidence of treatment-related deaths.
Pretreatment extraperitoneal staging of patients with bulky or locally advanced cervical carcinoma may afford a survival benefit via the debulking of macroscopically positive lymph nodes without significantly increasing treatment-related morbidity or mortality.
对于体积较大或局部晚期宫颈癌患者,在放疗前常规进行腹膜外手术分期仍存在争议。
对266例宫颈癌患者进行回顾性研究,这些患者在接受放疗前接受了腹膜外盆腔和腹主动脉旁淋巴结清扫术。根据患者的淋巴结状态进行分组。A组淋巴结阴性;B组有镜下可切除的淋巴结转移;C组有手术时可切除的肉眼可见阳性淋巴结;D组有不可切除的淋巴结。所有患者均接受了包括外照射和近距离放疗的标准放疗。有淋巴结转移的患者接受扩大野照射。采用Kaplan-Meier乘积限法计算生存概率,通过Mantel-Cox对数秩检验确定统计学意义。
50%的患者检测到淋巴结转移。B组和C组所有患者的5年和10年无病生存率相似。D组所有患者均复发。严重放疗相关并发症的发生率为10.5%,治疗相关死亡的发生率为1.1%。
对于体积较大或局部晚期宫颈癌患者,放疗前进行腹膜外分期可能通过切除肉眼可见的阳性淋巴结而带来生存获益,且不会显著增加治疗相关的发病率或死亡率。
