| Abstract |
The Lower Anogenital Squamous Terminology (LAST) Standardization Project for human papilloma virus (HPV)-associated lesions specifically recommends the use of p16 immunohistochemistry (IHC) as an adjunct to morphologic assessment of cervical biopsies interpreted as negative or low-grade squamous intraepithelial lesion (LSIL) from patients with prior high-risk Pap test results (high-grade squamous intraepithelial lesion [HSIL], atypical squamous cells cannot exclude HSIL, atypical glandular cells [AGC], or HPV16 atypical squamous cells of undetermined significance [ASC-US]). The impetus for this recommendation is to increase detection of missed high-grade disease. However, the quality of evidence supporting this recommendation was lower than that for the other LAST recommendations addressing improved consistency in the diagnosis of HSIL with the use of p16. A database search spanning 10 years identified 341 cases (encompassing 736 discrete biopsy specimens) interpreted as negative for dysplasia from 330 patients with a prior high-risk Pap result (atypical squamous cells cannot exclude HSIL, HSIL, atypical glandular cells, not otherwise specified [AGC-NOS], atypical endocervical cells--NOS [AEC-NOS], and AEC-favor neoplastic). p16 IHC was performed and detected missed abnormalities in 11/341 (3.2%) cases. The abnormalities corresponded to missed foci of HSIL (cervical intraepithelial neoplasia [CIN] 2) (n=1), SIL-indeterminate grade (n=7), atypical squamous metaplasia (n=2), and LSIL [CIN1]) (n=1). Subsequent histologic follow-up identified HSIL or greater in 6/8 (75%) p16 cases versus 20/79 (25.3%) p16 cases (P=0.0079). p16 IHC performed on biopsies interpreted as negative from patients with prior high-risk Pap test results increased the detection rate of missed SIL. A p16 result also significantly increased the likelihood of HSIL on subsequent biopsy. Although further studies are required to determine what percentage of missed HSIL justifies the additional cost, improved detection of HSIL in high-risk patients may lead to fewer diagnostic procedures and fewer patients lost to follow-up. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 January 2018.
All research outputs
#14,834,427
of 25,727,480 outputs
Outputs from The American Journal of Surgical Pathology
#2,186
of 3,550 outputs
Outputs of similar age
#225,158
of 452,511 outputs
Outputs of similar age from The American Journal of Surgical Pathology
#30
of 49 outputs
Altmetric has tracked 25,727,480 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,550 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one is in the 37th percentile – i.e., 37% of its peers scored the same or lower than it.
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 452,511 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 49 others from the same source and published within six weeks on either side of this one. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
