| Abstract |
A growing body of research describes cancers other than breast and ovarian in families with BRCA1/2 mutations, but the prevalence and characteristics of pancreatic cancer in these families has not been well described. This study was designed to: (1) estimate the prevalence of pancreatic cancer in BRCA1/2 positive families; (2) ascertain age of onset and gender distribution of pancreatic cancer in this cohort; and (3) compare age and gender characteristics of pancreatic cancer in BRCA1/2 positive families with those of the general population. Within the UCSF Cancer Risk Program cohort, 24/219 (11.0%) BRCA1 and 17/156 (10.9%) BRCA2 families had at least 1 individual with pancreatic cancer. In the 24 BRCA1 families, median age of diagnosis was 59 (range 45-80) in males, and 68 (range 38-87) in females (male:female ratio = 2.00). In the 17 BRCA2 families, median age of diagnosis was 67 (range 39-78) in males and 59 (range 46-81) in females (male:female ratio = 1.11). The SEER database, which describes cancer characteristics in a representative sample of the US population, reports a median age of 70 in males and 74 in females (male:female ratio = 0.96) over the same time period. Additionally, mean ages of diagnosis of pancreatic cancer in BRCA1/2 families differ significantly from the SEER mean (P = 0.0014 for BRCA1 and P = 0.011 for BRCA2 by unpaired t-test). Our findings suggest that families with early onset pancreatic cancer and features of hereditary breast and ovarian cancer should be considered for BRCA1/2 testing. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 26 August 2012.
All research outputs
#18,313,878
of 22,675,759 outputs
Outputs from Familial Cancer
#416
of 558 outputs
Outputs of similar age
#83,037
of 90,266 outputs
Outputs of similar age from Familial Cancer
#2
of 2 outputs
Altmetric has tracked 22,675,759 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 558 research outputs from this source. They receive a mean Attention Score of 4.2. This one is in the 14th percentile – i.e., 14% 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 90,266 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 3rd percentile – i.e., 3% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 2 others from the same source and published within six weeks on either side of this one.
