| Abstract |
An alternatively spliced transcription factor that participates in the unfolded protein response, XBP1 is a novel protein involved in cancer progression and outcome. This study aimed to investigate the relationship of spliced XBP1 (XBP1s) with the clinicopathological characteristics and prognosis of breast cancer by using tissue-microarray analysis. A consecutive series of 170 patients with breast cancer diagnosed between 2001 and 2004 in hospitals in eastern and southern China were included. Immunohistochemical staining for XBP1s was performed, and the expression of XBP1s was separately examined in nuclei and cytoplasm. We found that a higher expression of XBP1s in nuclei strongly correlated with poorer survival (46.7% versus 75%, P=0.018); however, the expression of XBP1s in the cytoplasm had no relationship with survival. Multivariate Cox regression analysis indicated that the expression of XBP1s was not an independent prognostic factor (RR 2.074, 95% CI 0.909-4.736; P=0.083). None of the other clinicopathological characteristics - age, pathology grade, T stage, N stage, TNM stage, estrogen receptor, progesterone receptor, or HER2 status - was found to be correlated with XBP1s expression in the nuclei. In conclusion, independently of other clinicopathological factors, the nuclear expression of XBP1s is correlated with shorter breast cancer survival; however, whether nuclear XBP1s is an independent prognostic biomarker needs to be confirmed by further studies with larger samples and detailed sample stratification. |

Attention Score in Context
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 13 December 2017.
All research outputs
#16,868,837
of 25,584,565 outputs
Outputs from OncoTargets and therapy
#979
of 2,967 outputs
Outputs of similar age
#267,257
of 446,259 outputs
Outputs of similar age from OncoTargets and therapy
#23
of 73 outputs
Altmetric has tracked 25,584,565 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,967 research outputs from this source. They receive a mean Attention Score of 3.0. This one has gotten more attention than average, scoring higher than 61% 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 446,259 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 73 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 64% of its contemporaries.
