Jirasak Sukhaboon Methods: Patients aged 18–70 years who had International Federation of Gynecology and https://orcid.org/0000-0002-4892-0645 Obstetrics stage IIB–IVA without para-aortic lymph node enlargement, Eastern Cooperative https://ejgo.org 1/13 Adjuvant chemotherapy for cervical cancer Somkit Penpattanagul Oncology Group scores 0–2, and non-aggressive histopathology were randomized to have https://orcid.org/0000-0001-5860-9554 CCRT with weekly cisplatin followed by observation (arm A) or by ACT with paclitaxel plus Apiradee Kridakara carboplatin every 4 weeks for 3 cycles (arm B). https://orcid.org/0000-0003-3286-5052 Results: Jitti Hanprasertpong Data analysis of 259 patients showed no significant difference in complete responses https://orcid.org/0000-0002-0640-6824 at 4 months after treatment between arm A (n=129) and arm B (n=130): 94.1% vs. 87.0% Kittisak Chomprasert (p=0.154) respectively. With the median follow-up of 27.4 months, 15.5% of patients in arm A https://orcid.org/0000-0002-8163-1626 and 10.8% in arm B experienced recurrences (p=0.123). There were no significant differences Sirentra Wanglikitkoon of overall or loco-regional failure. However, systemic recurrences were significantly lower https://orcid.org/0000-0003-1798-8871 in arm B than arm A: 5.4% vs. 10.1% (p=0.029). The 3-year progression-free survival (PFS) Thiti Atjimakul https://orcid.org/0000-0003-3460-8236 and 3-year overall survival (OS) of the patients in both arms were not significantly different. Piyawan Pariyawateekul The hazard ratio of PFS and OS of arm B compared to arm A were 1.26 (95% CI=0.82–1.96; https://orcid.org/0000-0001-7705-6537 p=0.293) and 1.42 (95% CI=0.81–2.49; p=0.221) respectively. Kanyarat Katanyoo Conclusions: ACT with paclitaxel plus carboplatin after CCRT did not improve response rate https://orcid.org/0000-0002-6561-5589 and survival compared to CCRT alone. Only significant decrease of systemic recurrences with Prapai Tanprasert https://orcid.org/0000-0002-9237-7539 ACT was observed, but not overall or loco-regional failure.

In Thailand, it is the second most common female cancer after breast cancer Vichan Lorvidhaya and remains the leading cause of death among women. An average age standardized https://orcid.org/0000-0001-8203-0761 incidence rate was 29.2 per 100,000 women with a death rate of 15.2 per 100,000 women or approximately half of its incidence [1]. This is probably due to a suboptimal screening Trial Registration ClinicalTrials.gov Identifier: NCT02036164 coverage of the target population, leading to a high proportion of locally advanced and Thai Clinical Trials Registry Identifier:TCTR advanced stage diseases and poor overall prognosis [2]. 20140106001 Concurrent chemoradiation therapy (CCRT) has been used as a standard treatment for locally Funding This trial was granted by the Thailand National advanced cervical cancer (LACC) for over two decades. Despite a survival improvement with Research Fund. an addition of concurrent chemotherapy to radiation, high rates of local and distant failures (17% and 18%, respectively) were still encountered [3].
