CYFRA 21-1 (cytokeratin 19 fragment) and C-reactive proteins (CRP) were separately reported to be associated with prognosis of head and neck squamous cell carcinoma. The combined roles of CYFRA 21-1 and CRP levels were rarely investigated in oral squamous cell carcinoma (OSCC). The purpose of the present study was to analyze the relationship between preoperative levels of both CYFRA 21-1 and CRP, with clinicopathological factors and prognosis in OSCC patients.
A retrospective study was performed on 130 OSCC patients between December 2010 and June 2013. Their serum CYFRA 21-1 and CRP levels were measured preoperatively.
CYFRA 21-1 level of ≥3.3 ng/mL and CRP level of ≥5.0 mg/L were significantly associated with pathological tumor status (P < 0.001), tumor depth (>10 vs. ≤10 mm, P = 0.001), bone invasion (P = 0.001), skin invasion (P = 0.006), pathologic nodal metastasis (P = 0.012), and disease-free survival (P = 0.009). Higher CYPFRA 21-1 and CRP levels were also associated with higher risks of distant metastasis (log-rank test, P = 0.013, (HR [95 % CI]) 1.692 [1.097-2.414]).
Preoperative CYFRA 21-1 and CRP levels are probable candidates as biomarkers for risk stratification in OSCC.
This research output has an Altmetric Attention Score of 2. 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 30 April 2016.
All research outputs
#13,953,851
of 22,824,164 outputs
Outputs from World Journal of Surgical Oncology
#408
of 2,043 outputs
Outputs of similar age
#132,905
of 266,184 outputs
Outputs of similar age from World Journal of Surgical Oncology
#5
of 41 outputs
Altmetric has tracked 22,824,164 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,043 research outputs from this source. They receive a mean Attention Score of 2.1. This one has done well, scoring higher than 78% 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 266,184 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 48th percentile – i.e., 48% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 41 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 82% of its contemporaries.
