老年宫颈癌患者的临床与预后分析

Clinical and prognostic analysis of elderly patients with cervical cancer

目的 探讨老年宫颈癌患者的预后及危险因素. 方法 回顾性分析2008年6月至2013年6月在浙江省肿瘤医院收治的≥65岁的老年宫颈癌患者337例,收集患者的临床资料及随访信息,分析年龄、体力状况评分(PS)、国际妇产科联盟(FIGO)分期、肿瘤大小、分化程度、病理类型、治疗方式、合并基础疾病与预后的相关性. 结果 337例宫颈癌患者中,Ⅰ期、Ⅱ期、Ⅲ期、Ⅳ期患者的5年总生存率分别为81.8% 、62.3% 、53.5% 、0.0% (χ2=63.414 ,P=0.000 ) ,局部复发率为33.5% ,合并基础疾病和无基础疾病患者的5年总生存率分别为54.0% 和70.0% (χ2=8.907 ,P=0.003) . 119例ⅠA ~ Ⅱ A 期宫颈癌患者中,手术组和放疗组的 5 年总生存率分别为 83.5% 和55.0% (χ2=13.161 ,P=0.000) ,218例中晚期宫颈癌患者中,放化疗组和放疗组的5年总生存率分别为69.7% 和51.9% (χ2=4.030 ,P=0.045) ,急性Ⅲ ~ Ⅳ度骨髓抑制发生率分别为42.4% 、9.7% (χ2=21.362 ,P=0.000) ,Ⅲ ~ Ⅳ度胃肠道反应发生率为9.1% 、5.9% (χ2=0.086 ,P=0.769). Cox回归多因素分析显示,年龄、体力状况(PS)评分、FIGO分期、病理类型、治疗方式、合并基础疾病是影响老年宫颈癌患者预后的因素(均 P<0.05) . 结论 老年宫颈癌患者治疗耐受性好;合并基础疾病是影响预后因素之一,行根治性放疗的早期患者,合并基础疾病比例高,疗效劣于手术;同步放化疗可改善中晚期老年宫颈癌患者的预后.

Objective To explore the prognosis and risk factors for cervical cancer in elderly patients. Methods Clinical data of 337 elderly patients (≥ 65 years old )admitted into Zhejiang Cancer Hospital from June 2008 to June 2013 were retrospectively analyzed.Clinical data and the follow-up information were collected. The correlation of prognosis with age ,performance status score , International Federation of Gynecology and Obstetrics (FIGO )staging ,tumor size ,pathological type , treatment and comorbidities were analyzed. Results Among 337 elderly patients ,the 5-year overall survival(OS )rates for patients with stage Ⅰ,Ⅱ,Ⅲ,Ⅳ were 81.8% ,62.3% ,53.5% and 0.0% , respectively (χ2=63.414 ,P=0.000) ;local recurrence rate was 33.5% ;the 5-year OS rate of patients with and without comorbidities were 54.0% and 70.0% ,respectively(χ2=8.907 ,P=0.003).Among 119 cervical cancer patients with stage ⅠA-ⅡA ,5-year OS for surgery group and radiotherapy group were 83.5% and 55.0% ,respectively(χ2=13.161 ,P=0.000).Among 218 advanced cervical cancer patients ,the 5 year OS for chemoradiotherapy and radiotherapy groups were 69.7% and 51.9% , respectively(χ2=4.030 ,P=0.045). The acute toxicity reactions of radiotherapy and chemoradiotherapy groups were as follows. The incidences of acute grades 3-4 hematological toxicity were 9.7% and 42.4% in radiotherapy group and chemoradiotherapy groups respectively (χ2=21.362 ,P=0.000) ,and the incidences of acute grade 3 gastrointestinal toxicity were 5.9% and 9.1% (χ2=0.086 ,P=0.769)in radiotherapy group and chemoradiotherapy group ,respectively.No grade 4 gastrointestinal toxicity was found.Multivariate Cox regression analysis showed that age ,PS score , FIGO staging ,pathological type ,treatment and comorbidities were influencing factors for prognosis in elderly patients with cervical cancer (P<0.05). Conclusions Elderly cervical cancer patients have a good tolerance to treatment. The comorbidity is one of negatively influencing factors for prognosis. The efficacy of definitive radiotherapy is inferior to surgery in elderly patients with early stage cervical cancer due to the high proportion of comorbidities.Concurrent chemoradiotherapy can improve the prognosis of middle and advanced cervical cancer in elderly patients.
