摘要
目的分析不同放疗方法对Ⅲ宫颈癌疗效和副反应的影响。方法回顾性分析763例接受全程放疗的Ⅲ期宫颈癌患者（鳞癌722例，腺癌41例）的生存率，对资料完整的350例进行近期疗效及放疗副反应的比较。763例中全盆2个野常规分割＋腔内放疗113例（CF组），盆腔盒式4个野加速超分割＋腔内放疗44例（AHF组），盆腔4个小野非常规分割同期腔内放疗606例（FRT组），61例加用了化疗。350例中CF组112例，AHF组44例，FRT组194例，61例加用了化疗。结果全部病例CF、AHF、FRT组3年生存率分别为65．7％、66．8％、44．3％（P=0．000），5年生存率分别为65．7％、66．8％、36．3％（P=0．ooo）；CF、FRT组10年生存率分别为43．3％、31．9％（P=0．200）；鳞癌加化疗组生存率高于无化疗组。350例中CF、AHF、FRT组局部控制率分别为83．0％、93．2％、86．1％（χ^2=2．70，P=0．259），急性放射性肠道、膀胱损伤发生率相似（P〉0．05），FRT组骨髓抑制率最低（56．2％；χ^2=25．95，P=0．000）；AHF组皮肤反应发生率最低（9．1％；χ^2=20．25，P=0．002）；鳞癌加化疗组生存率高于无化疗组，但骨髓抑制及肠道反应均高于无化疗组。结论CF组及AHF组5年生存率均较好，AHF组的并发症较轻、疗程短并有提高局部控制率的趋势，值得推广应用。同步放化疗可改善鳞癌患者的生存率及近期疗效，但并发症显著增加，治疗要考虑患者体质、对化疗的耐受程度等。
Objective To evaluate the clinical value of different radiotherapy protocols in the treatment of advanced cervical cancer. Methods From 1976 to 2006,763 patients with stage Ⅲ cervical cancer（722 with squamous cell carcinoma and 41 with adenocarcinoma）were treated by radiotherapy in our hos- pital. 113 patients were treated by two-field whole pelvic irradiation in conventional fractionation plus brachytherapy（ CF group）, 44 by four-field whole pelvic irradiation in accelerated hyperfractionation plus brachytherapy（ AHF group） ,and 606 by concomitant four-field unconventional fractionation radiotherapy and brachytherapy（ FRT group）. Sixty-one patients were treated by radiotherapy and chemotherapy. Among 350 patients who had complete data,the short-term efficacy and toxicities were compared. Results For patients in CF, AHF and FRT groups, the 3-year overall survival rates （OS） were 65.7% , 66.8% and 44.3% , respectively （ P = 0. 000）, and the 5 -year OS were 65.7 %, 66.8 % and 36.3 %, respectively （ P = 0. 000）. The 10-year OS were 43.3 % and 31.9% in CF and FRT groups （P = 0. 200）. For squamous cell carcinoma, the OS was higher of patients with chemotherapy than those without. In 350 patients who had complete data,the local control rates of CF,AHF and FRT groups were 83.0% ,93.2% and 86.1% ,respectively（ χ^2 =2.70,P =0. 259）;AHF group had the lowest side effect rate, especially skin reaction （9.1%, χ^2= 20.25, P = 0. 002） ;CF group had the lowest acute bone marrow suppression rate（ χ^2 =25.95 ,P =0. 000） ;for squamous cell carcinoma,the OS was higher in patients with chemotherapy than those without;the acute bone marrow and intestinal toxicities were more in patients with chemotherapy than those without. Conclusions CF and AHF groups have similar 5-year OS of patients with advanced cervical cancer. AHF group has less toxicities, shorter treatment course and a trend of better local control. Concurrent chemoradiation could improve survival and local control of the patients with advanced squamous cell cervical cancer while increase the side effects. The individual condition should be considered to choose the treatment protocol.
