About this study
Official title: CNG Staging Compared With UICC Eighth Staging of Nasopharyngeal Carcinoma for Treatment Decision-marking and Selection of Chemotherapy and Radiotherapy： a Multicenter, Open Label, Randomized Controlled, Non-inferiority Clinical Trial
Due to the increase of tumor control rate and survival rate in era of IMRT, the role of the seventh edition of UICC/AJCC staging system in predicting prognosis is becoming weaker and inaccurate.
Therefore, we put forward a new staging for the clinical staging of NPC in the era of IMRT without changing the current T, N, M staging definition of the 7th of the UICC/AJCC staging system. We call this new stage "Cooperative Nasopharyngeal Carcinoma Group" stage, namely CNG stage. In CNG stage, the clinical stages were reduced to three stages, namely, CNG I stage includes T1-3N0-1M0 and T1-2N2M0, CNG II stage includes T3N2M0, T4N0-2M0 and TanyN3M0, CNG III stage includes TanyNanyM1. For CNG I stage, the IMRT alone is sufficient. If EBV-DNA copies is more than 0 copy/ml, concurrent chemoradiotherapy will be given. For CNG II stage, patients can benefit from combined radiotherapy and chemotherapy. For CNG III stage, patients are recommended for systemic chemotherapy plus local radiotherapy (primary focus, neck drainage area and distant metastasis).

This year, UICC/AJCC has proposed an eighth edition of NPC staging system. The eighth version is mainly changed in the definition and refinement of the anatomic location compared with the seventh edition. This is different from our new CNG staging concept.
Therefore, CNG staging and its treatment strategy was used as the experimental group, and the eighth edition of UICC/AJCC staging with NCCN guiding treatment was used as the control group. The open and randomized controlled clinical study was conducted. The purpose of this study was to evaluate in the era of IMRT, CNG staging can be better than UICC/AJCC eighth clinical staging for treatment decision-marking and selection of chemotherapy and radiotherapy, and differentiating differences in prognosis in each clinical stage. The survival results based on CNG staging and its treatment are not inferior to the survival results of the NCCN guide therapy based on the eighth edition UICC/AJCC staging, to avoid chemotherapy for some of the patients, and to improve the outcome of metastatic patients.
Read the detailed description
The seventh edition of the UICC/AJCC staging system, which is widely used in recent years, is based on survival data in the traditional era of radiotherapy. However, the survival of nasopharyngeal cancer patients has been greatly improved in the era of modern radiation therapy, which IMRT (Intension Modulated Radiotherapy) is widely used. Even with radiotherapy alone, the 5 year disease specific survival rate of nasopharyngeal carcinoma with stage I-II is more than 95%, the 3 year overall survival rate of non metastatic III-IV patients is about 75%, and the 5 year overall survival rate is about 80%. The 5 year survival rate of metastatic nasopharyngeal carcinoma can reach more than 20% with systemic treatment. Due to the increase of tumor control rate and survival rate in era of IMRT, the role of the seventh edition of UICC/AJCC staging system in predicting prognosis is becoming weaker and inaccurate.
Therefore, in the previous study, we put forward a new staging for the clinical staging of nasopharyngeal carcinoma in the era of IMRT without changing the current T, N, M staging definition of the seventh edition of the UICC/AJCC staging system. We call this new stage "Cooperative Nasopharyngeal Carcinoma Group" stage, namely CNG stage. In CNG stage, the clinical stages were reduced to three stages, namely, CNG I stage includes T1-3N0-1M0 and T1-2N2M0, CNG II stage includes T3N2M0, T4N0-2M0 and TanyN3M0, CNG III stage includes TanyNanyM1, and the 5 year DSS (Disease specific survival) is 93.3%, 72.7%, and 24%, respectively, with a significant difference.
This year, UICC/AJCC has proposed an eighth edition of nasopharyngeal carcinoma staging system based on the revision of the seventh edition. The main updates are: (1) add the definition of the T0 phase, that is, the EBV positive cervical lymph node metastases with uncertain primary foci, and (2) the invasion of the adjacent muscles (including the pterygus, the extradypterygus, and the anterior vertebroid muscle) into T2; (3) replace the "masticatory muscle space" and "subtemporal fossa" in the previous T4 definition with a specific description of soft tissue invasion; (4) change the supraclavicular fossa to the lower neck (defined as the lymph node metastases below the subchondral edge); (5) N3a and N3b are combined called N3, and it is defined as a single / double neck lymph node with long diameter > 6cm, and/or below the subchondral subchondral edge; (6) the IVA stage (T4 N0-2 M0) and the IVB stage (anyT N3 M0) are combined called IVA stage; (7) the IVC stage (anyT anyN) is changed to IVB stage. The eighth version is mainly changed in the definition and refinement of the anatomic location compared with the seventh edition. Except for the migration of the adjacent muscle invasion, and the other changes are not significant. The upper bound of N3 is moved from the supraclavicular fossa to the subchondral edge in N staging. This is different from our new CNG staging concept.
CNG staging of nasopharyngeal carcinoma is related to the unique biological behavior of nasopharyngeal carcinoma, which is consistent with the three clinical patterns of nasopharyngeal carcinoma, namely, non metastasis, tendency to metastasis and metastasis. The pattern of tendency to metastasis was related to the late T and N staging. Based on the biological behavior and clinical survival data of NPC, we further proposed the treatment strategy of nasopharyngeal carcinoma under the guidance of CNG staging, that is, the CNG I stage is consistent with the non metastasis model, and the IMRT alone is sufficient. The CNG II stage is consistent with the tendency to metastasis mode, which can benefit from combined radiotherapy and chemotherapy. The CNG III stage is metastatic mode, which is recommended for systemic chemotherapy plus local radiotherapy (primary focus, neck drainage area and distant metastasis). In clinical practice, we suggest that for patients with CNG I stage, if EBV-DNA copies is more than 0 copy/ml, concurrent chemoradiotherapy will be given.
Therefore, CNG staging and its treatment strategy was used as the experimental group, and the eighth edition of UICC/AJCC staging with NCCN guiding treatment was used as the control group. The open and randomized controlled clinical study was conducted. The purpose of this study was to evaluate in the era of IMRT, CNG staging can be better than UICC/AJCC eighth clinical staging for treatment decision-marking and selection of chemotherapy and radiotherapy, and differentiating differences in prognosis in each clinical stage. The survival results based on CNG staging and its treatment are not inferior to the survival results of the NCCN guide therapy based on the eighth edition UICC/AJCC staging, to avoid chemotherapy for some of the patients, and to improve the outcome of metastatic patients.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing CNG Chemotherapy, NCCN Chemotherapy and CNG Radiation in people with Nasopharyngeal Carcinoma, run by Sun Yat-sen University.
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 10 inclusion and 2 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 18 May 2018. Status can change between updates, so confirm with the study contact before making plans.
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 Yun-fei Xia, M.D (86-13602805461, xiayf@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall Survival (OS) (time frame: From the date of randomization until the date of death, assessed up to 60 months). 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 NCT03529279, which also lists 1 linked publication.
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 18 May 2018.
