To evaluate the benefit with the addition of paclitaxel to cisplatin-based concurrent chemoradiotherapy (C-CRT) for the treatment of locally advanced carcinoma of the uterine cervix in terms of local control, disease free survival (DFS) and overall survival (OS).
From 1/7/2011 to 31/5/2012, 81 women (median age of 50 years) with newly diagnosed, histopathologically proven carcinoma cervix with FIGO stages IIA to IIIB were randomized to two arms-cisplatin 40 mg/m(2)/week for 5 weeks was given in single agent cisplatin (control arm), while cisplatin 30 mg/m(2)/week and paclitaxel 50 mg/m(2)/week for 5 weeks were given in cisplatin and paclitaxel (study arm). External beam radiotherapy (EBRT) was delivered to a total dose of 50 Gray (Gy) in 25 fractions (#) followed by intracavitary (I/C) brachytherapy or supplement EBRT at 20 Gy/10# with 2 cycles of respective chemotherapy. This prospective trial was registered with clinicaltrials.gov (NCT01593306).
Patients (n=81) had a maximum follow up of 36 months with a median follow up of 29 months. At first follow up study arm showed complete response in 84% vs. 75.6% in control arm (P=0.4095). An increase in toxicities was observed in the study arm in comparison to the control arm in terms of haematological grade II (35% vs. 12.2%), gastrointestinal (GI) grade III (20% vs. 7.4%) and GI grade IV (12.5% vs. 2.4%) toxicities. At median follow-up, the study arm demonstrated enhanced outcomes over the control arm in terms of DFS (79.5% vs. 64.3%; P=0.07) and OS (87.2% vs. 78.6%; P=0.27).
Despite the expected increase in manageable toxicities, these early results reveal promise with the inclusion of paclitaxel into the standard cisplatin based chemoradiation regime. Larger multi-institutional studies are justified to confirm a potential for the enhancement of response rates and survival.
评估紫杉醇联合顺铂同期放化疗(C-CRT)治疗局部晚期宫颈癌的疗效,包括局部控制、无病生存(DFS)和总生存(OS)。
2011 年 7 月 1 日至 2012 年 5 月 31 日,81 例新诊断的宫颈鳞癌患者(中位年龄 50 岁),国际妇产科联盟(FIGO)分期为 IIA 至 IIIB 期,随机分为两组:顺铂 40mg/m2/周(单药顺铂组),顺铂 30mg/m2/周联合紫杉醇 50mg/m2/周(顺铂联合紫杉醇组),共 5 周。外照射放疗(EBRT)剂量为 50Gy/25 次(#),随后行腔内(I/C)近距离放疗或补充外照射放疗 20Gy/10#,2 个周期的相应化疗。这项前瞻性试验在临床试验.gov(NCT01593306)上注册。
81 例患者(n=81)的随访时间最长为 36 个月,中位随访时间为 29 个月。首次随访时,研究组完全缓解率为 84%,对照组为 75.6%(P=0.4095)。与对照组相比,研究组的血液学 2 级毒性(35% vs. 12.2%)、胃肠道(GI)3 级毒性(20% vs. 7.4%)和 GI 4 级毒性(12.5% vs. 2.4%)发生率更高。中位随访时,研究组在 DFS(79.5% vs. 64.3%;P=0.07)和 OS(87.2% vs. 78.6%;P=0.27)方面的结果优于对照组。
尽管预计毒性会增加,但这些早期结果显示,在顺铂为基础的放化疗方案中加入紫杉醇具有一定的前景。有必要进行更大规模的多机构研究,以确认提高反应率和生存率的潜力。
