| Abstract |
Narrow-band imaging (NBI) is an endoscopic technique enhancing mucosal vasculature and better identifying superficial carcinomas due to their neo-angiogenic pattern. NBI accuracy is increased by combination with a high-definition television (HDTV) camera. The aim of this report was to evaluate the diagnostic improvement of NBI +/- HDTV in the evaluation of head and neck squamous cell cancer (HNSCC) previously treated by chemo-radiotherapy (CHT-RT) or RT. A total of 390 patients affected by HNSCC were prospectively evaluated by NBI and white light (WL) endoscopy +/- HDTV between April 2007 and April 2009 at a single academic institution. Among them, we focused on 59 (15%) patients who received CHT-RT or RT as part of their treatment. Of 59 patients, 13 (22%) showed adjunctive preoperative NBI findings when compared to the standard WL examination. These findings were always confirmed by intraoperative HDTV NBI, while only eight (62%) were visible with HDTV WL. Of 13 lesions, 12 received histopathologic confirmation (from carcinoma in situ to invasive carcinoma). The sensitivity of flexible NBI, HDTV WL, and HDTV NBI was 100, 66 and 100%, respectively. The specificity was 98, 100, and 98%. The positive predictive value was 92, 100, and 92%. The negative predictive value was 100, 94, and 100%. The accuracy was 98, 91, and 98%. NBI +/- HDTV after CHT-RT or RT was of value in detecting tumor persistence (n = 2), early recurrences (n = 6), and metachronous tumors (n = 4). By contrast, only 1 of 59 (2%) patients was found to be false positive. |

Attention Score in Context
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 02 February 2016.
All research outputs
#6,377,613
of 22,660,862 outputs
Outputs from European Archives of Oto-Rhino-Laryngology
#325
of 3,033 outputs
Outputs of similar age
#30,135
of 94,908 outputs
Outputs of similar age from European Archives of Oto-Rhino-Laryngology
#2
of 12 outputs
Altmetric has tracked 22,660,862 research outputs across all sources so far. This one has received more attention than most of these and is in the 70th percentile.
So far Altmetric has tracked 3,033 research outputs from this source. They receive a mean Attention Score of 3.1. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 94,908 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
We're also able to compare this research output to 12 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 83% of its contemporaries.
