- Post radiotherapy 8 weeks NPC patient
- description
- All post-radiotherapy 8 weeks NPC patient will routinely undergo laryngoscope examination (WL system) and NP biopsy will be taken at the same time to determine if there is any residual NPC. In this study, laryngoscope with NBI system will be used. NBI system will be turn on during the post radiotherapy 8 week laryngoscope examination in additional to routine WL system

- Positive Nasopharynx Biopsy Results Detected by NBI System in Those Post-radiotherapy 8th Week NPC Patient
- timeFrame
- Post-radiotherapy 8th week
- description
- 4 grading of NBI vessel patterns can be identified in those post-radiotherapy 8 weeks NPC patients. Grade A: normal vessel size and length, regular pattern Grade B: normal vessel size, short, regular spiderweb like pattern Grade C: irregular vessel size and length, distorted and irregular pattern Grade D: thickened vessel size, elongated, distorted, and earthworm pattern
