| Abstract |
The outcome of radical surgery for lung cancer was investigated in patients with combined pulmonary fibrosis and emphysema (CPFE). A retrospective chart review involved 250 patients with lung cancer who underwent pulmonary resection at Tokyo Women's Medical University Yachiyo Medical Center between 2008 and 2012. Based on the status of nontumor-bearing lung evaluated by preoperative computed tomography (CT), the patients were divided into normal, emphysema, interstitial pneumonia (IP), and CPFE groups, and their clinical characteristics and surgical outcome were analyzed. The normal, emphysema, IP, and CPFE groups comprised 124 (49.6%), 108 (43.2%), seven (2.8%), and eleven (4.4%) patients, respectively. The 5-year survival rate of the CPFE group (18.7%) was significantly lower than that of the normal (77.5%) and emphysema groups (67.1%) (P<0.0001 and P=0.0027, respectively) but equivalent to that of the IP group (44.4%) (P=0.2928). In a subset analysis of cancer stage, the 5-year overall survival rate of the CPFE group in stage I (n=8, 21.4%) was also lower than that of the normal group and emphysema group in stage I (n=91, 84.9% and n=70, 81.1%; P<0.0001 and P<0.0001, respectively). During entire observation period, the CPFE group was more likely to die of respiratory failure (27.2%) compared with the normal and emphysema groups (P<0.0001). Multivariate analysis of prognostic factors using Cox proportional hazard model identified CPFE as an independent risk factor (P=0.009). CPFE patients have a poorer prognosis than those with emphysema alone or with normal lung on CT finding. The intensive evaluation of preoperative CT images is important, and radical surgery for lung cancer should be decided carefully when patients concomitantly harbor CPFE, because of unfavorable prognosis. |

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 01 July 2016.
All research outputs
#17,286,645
of 25,374,917 outputs
Outputs from International Journal of Chronic Obstructive Pulmonary Disease
#1,731
of 2,577 outputs
Outputs of similar age
#225,314
of 353,658 outputs
Outputs of similar age from International Journal of Chronic Obstructive Pulmonary Disease
#61
of 83 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 21st percentile – i.e., 21% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,577 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one is in the 24th percentile – i.e., 24% 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 353,658 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 28th percentile – i.e., 28% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 83 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
