Randomized Control Trial on Efficacy and Safety of Concurrent and Adjuvant Chemotherapy for the Cervical Cancer
A Phase 3 study testing concurrent chemotherapy with cisplatin, concurrent chemotherapy with docetaxel and pelvic radiotherapy in people with Cervical Cancer, run by Air Force Military Medical University, China at 3 sites in China.
Trial summary
The standard treatment of local advanced cervical cancer is concurrent chemoradiotherapy. The 3 year disease free survival was about 50-70%. The distant metastasis is the main cause of failure in local advanced cervical cancer treated with 3-dimensional conformal radiotherapy (3D-CRT) or intensity modulated… Read more about this study

About this study
Official title: Multicenter Study on Efficacy and Safety of Concurrent and Adjuvant Chemotherapy With Cisplatin and Docetaxel Combined With Radiotherapy for Local Advanced Cervical Cancer
The standard treatment of local advanced cervical cancer is concurrent chemoradiotherapy. The 3 year disease free survival was about 50-70%. The distant metastasis is the main cause of failure in local advanced cervical cancer treated with 3-dimensional conformal radiotherapy (3D-CRT) or intensity modulated radiotherapy (IMRT). The purpose of this study is to investigate the efficacy and tolerance of concurrent and adjuvant chemotherapy with cisplatin and docetaxel for local advanced cervical cancer. It was expected that the 3 year disease free survival would be increased by 10% with this new treatment schedule.
Read the detailed description
The cervical cancer is the most common malignant gynecological tumor in the developing area. From 1999, the concurrent chemoradiotherapy has been established as the standard treatment for local advanced cervical cancer. The modern radiotherapy techniques, such as 3 dimensional conformal radiotherapy(3D-CRT), intensity modulated radiotherapy(IMRT), image guided 3-dimensional brachytherapy(3D-BT), was widely used for the treatment of cervical cancer. The recently clinical outcome showed that the 3 year local and regional control was more than 90%[1-3]. The distant metastasis has proved to be the main cause of failure and death, especially for the patient with pelvic lymph node metastasis, large volume of tumor and advanced FIGO stage. the data showed that the 3 year distant metastasis free survival and overall survival were 64.7% and 64.6% respectively for the patient with huge pelvic lymph node metastasis and FIGO stage III- IVA. The system treatment pointing at the distant metastasis has become to be the topic of clinical investigation.
Dueñas-González A'[4] study demonstrated that the 3 year progress free survival and distant metastasis free survival has increased by 8.9% and 8.3% by the radial radiotherapy combined with concurrent chemotherapy with weekly gemcitabine and cisplatin and adjuvant chemotherapy with triweekly gemcitabine and cisplatin. Ryu SY[5] also reported the triweekly concurrent cisplatin with 3 cycles improved survival outcomes compared with weekly concurrent cisplatin. Retrospective studies by Tang and Jelavić-TB[6-7] suggested that the adjubant chemotherapy after CCRT has better DMFS and OS.
The aim of present study is to prospectively investigate the efficacy and safety of concurrent and adjuvant chemotherapy with cisplatin and docetaxel for patients with local advanced cervical cancer, especially for those with FIGO III-IVA with or without pelvic lymph node metastasis and the FIGO IB2-IIB with pelvic lymph node metastasis.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing concurrent chemotherapy with cisplatin, concurrent chemotherapy with docetaxel and pelvic radiotherapy in people with Cervical Cancer, run by Air Force Military Medical University, China at 3 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact mei shi, professor (0086-029-84775432, mshi82@fmmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
disease free survival (time frame: 3 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02703961, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Mar 2016.
