Dual-energy CT combined with nasopharyngeal endoscopy to detect nasopharyngeal carcinoma
Screening Effect of Dual-energy CT Combined With Nasopharyngeal Endoscopy for Screening Nasopharyngeal Carcinoma
This project will test whether doing dual-energy CT first and then nasopharyngeal endoscopy can better find nasopharyngeal carcinoma in adults who have high EBV-related blood markers.

What this trial studies
Participants are screened with EBV-related blood tests (EBNA1-IgA, VCA-IgA, and BNLF2b/P85-Ab) and those with high serologic risk are selected for imaging. Selected participants undergo dual-energy CT first to record suspected nasopharyngeal lesions, followed by nasopharyngeal endoscopy to document visually suspicious areas. Biopsies are then taken from lesion sites indicated by CT and from suspicious sites found by endoscopy to obtain pathological confirmation. The study is observational and performed at Zhongshan People's Hospital in Zhongshan, Guangdong.
Who should consider this trial
Good fit: Ideal candidates are residents of Zhongshan City without a prior diagnosis of nasopharyngeal carcinoma who can give informed consent, are in stable health, have high EBV serologic risk, and have no contraindications to contrast CT or endoscopy.
Not a fit: Patients with contrast media allergy, contraindications to nasopharyngeal endoscopy, severe cardiovascular/liver/kidney disease, or low EBV serologic risk are unlikely to receive benefit from this protocol.
Why it matters
Potential benefit: If successful, this approach could lead to earlier and more accurate detection of nasopharyngeal carcinoma by combining targeted imaging with endoscopic biopsy.
How similar studies have performed: EBV serology and endoscopic biopsy are established tools for NPC detection and dual-energy CT has shown promise for lesion characterization, but the specific combination and sequencing used here is not yet widely validated.
