Description
The prognosis of cancer patients is highly dependent on the time of diagnosis. Early, stage 1 disease is often curable whereas late stage diseases are usually beyond curable treatments. Therefore, new diagnostic tools for malignancies of the upper aerodigestive tract are developed all the time and narrow band imaging (NBI) is one of these new options for early diagnostics. In this paper, we describe the implementation of NBI technique in our institution. During the first 6 weeks we used NBI to examine 73 patients with different types of pharyngeal or laryngeal problems. Most of the patients (77%) were on follow-up visits after earlier malignant disease. In our series we had 11 NBI-positive patients and the histological diagnosis was carcinoma or dysplasia among 10 of these. Among the NBI negative patients we found four carcinomas. It is notable that NBI affected the decision of a biopsy procedure in three patients, with final diagnosis of dysplasia or carcinoma. In conclusion, we find NBI useful in the diagnostics of malignancies of the upper aerodigestive tract. This is a useful tool in improving the accuracy of the diagnostics. However, it still takes an experienced clinician and a learning curve can be expected.
