Primary Non-Hodgkin's lymphoma of the gallbladder (PNHL-GB) is extremely rare and data on clinical characteristics, optimal management and outcomes of these patients are limited to anecdotal reporting. We, therefore, sought to examine these patients using a population-based database.
Surveillance, epidemiology, and end results (SEER) database was queried between 1973 and 2013.
One hundred and six cases with PNHL-GB were identified (mean age=70.5 ±15 years, whites 92%, male: female 1.03:1). The majority of patients had loco-regional disease (61%) and DLBCL histology (33%). Ninenty cases (85%) had undergone surgical resection, 6 (5.6%) received radiotherapy. Median overall survival (OS) of the entire cohort was 41 months with a 5-year survival rate of 40%. Patients receiving adjuvant RT had superior OS compared to surgery alone (140 ±27 vs. 86 ±16 months, respectively) and patients with DLBCL demonstrated lower survival compared to other histologies (13 vs. 53 months, respectively, p=0.034).
Our study presents the largest dataset of PNHL-GB describing clinical features and outcomes of these patients in addition to summarizing the literature.
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 10 May 2017.
All research outputs
#31,228,352
of 34,411,289 outputs
Outputs from Anticancer Research: International Journal of Cancer Research and Treatment
#6,843
of 8,157 outputs
Outputs of similar age
#318,568
of 355,920 outputs
Outputs of similar age from Anticancer Research: International Journal of Cancer Research and Treatment
#80
of 102 outputs
Altmetric has tracked 34,411,289 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 8,157 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 1st percentile – i.e., 1% 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 355,920 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 102 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
