Online adaptive radiotherapy for nasopharyngeal carcinoma

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase III clinical trial involves treatment-naïve patients with nasopharyngeal carcinoma who will be randomly assigned to receive either online adaptive radiotherapy (ART) with a smaller planning target volume (PTV) margin or conventional radiotherapy with a standard PTV margin. The study aims to compare the locoregional recurrence-free survival rates, adverse events, and quality of life between the two treatment approaches. By utilizing online ART, the trial seeks to determine its effectiveness in reducing radiation toxicity while maintaining treatment efficacy.

Inclusion Criteria:

1. Newly diagnosed nasopharyngeal carcinoma confirmed by pathology, with a histological classification of non-keratinizing carcinoma (according to the World Health Organization, WHO), pathological classification.
2. No evidence of distant metastasis (M0).
3. Age between 18 and 70 years.
4. Eastern Cooperative Oncology Group (ECOG) performance status score:0-1.
5. Undergoing radical intensity-modulated radiation therapy (IMRT).
6. No claustrophobia and able to remain in a fixed position for at least 30 minutes
7. Patients must be informed of the main content of this study, sign an informed consent form, and be willing and able to comply with the treatment, follow-up plan, laboratory tests, and other requirements specified in the study protocol.

Exclusion Criteria:

1. Histological types include squamous cell carcinoma or basal cell carcinoma.
2. Radiation therapy intended for palliative care.
3. History of malignant tumors, excluding adequately treated basal cell carcinoma, squamous cell carcinoma, and cervical intraepithelial neoplasia.
4. Pregnant or lactating women (women of childbearing age should undergo pregnancy testing; effective contraception should be emphasized during treatment.
5. Previous radical radiotherapy for nasopharyngeal cancer.
6. Primary and neck metastatic lesions treated with chemotherapy or surgery.
