Abstract

The risk of cancer is increased and affects survival after lung transplantation (LTx), but has not been well characterized in COPD. We aimed to evaluate the incidence and prognosis of cancer following LTx for COPD. A prospective, population-based study of patients undergoing LTx for end-stage COPD at the two transplantation centers in Sweden between 1990-2013, with follow-up for incident cancer and death, using national registers. The excess risk of cancer was calculated as standardized incidence ratios compared with the general population matched for age, sex, and calendar year. Risk factors for cancer were analyzed using Fine-Gray regression, and survival after cancer diagnosis with Kaplan-Meier. In total, 331 patients (mean age 55.4 years; 64% women; 97% former smokers) were included. At a median follow-up of 2.8 years, 35% of patients had developed cancer and the risk was increased more than 10-fold ([95% CI] 8.1-11.8). The highest excess risks were for non-Hodgkin lymphoma (20.8-66.7), skin cancer (20.3-35.2), lung (11.7-31.2), liver (3.6-51.6), and colorectal cancer (6.1-19.5). Median survival was longer for skin cancer (8 years; 95% CI, 3-15) compared with non-skin cancer (4 years; 95% CI, 2.8-4.8; p<0.001). The cancer risk is markedly increased after LTx for COPD. It could not be predicted by the factors evaluated, but contributed significantly to a negative prognosis.

Attention Score in Context

This research output has an Altmetric Attention Score of 5. 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 12 June 2018.
All research outputs
#3,232,631
of 13,073,426 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#402
of 1,589 outputs
Outputs of similar age
#91,782
of 311,402 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#15
of 61 outputs
Altmetric has tracked 13,073,426 research outputs across all sources so far. Compared to these this one has done well and is in the 75th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,589 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.0. This one has gotten more attention than average, scoring higher than 74% 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 311,402 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 61 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 75% of its contemporaries.
