| Abstract |
Survival nomograms offer individualized predictions using a more diverse set of factors than traditional staging measures, including the American Joint Committee on Cancer Tumor Node Metastasis (AJCC TNM) Staging System. A nomogram predicting overall survival (OS) for resected, non-metastatic non-small cell lung cancer (NSCLC) has been previously derived from Asian patients. The present study aims to determine the nomogram's predictive capability in the US using the National Cancer Database (NCDB). This was a retrospective review of adults with resected, non-metastatic NSCLC entered into the NCDB between 2004 and 2012. Concordance indices and calibration plots analyzed discrimination and calibration, respectively. Multivariate analysis was also used. A total of 57,313 patients were included in this study. The predominant histologies were adenocarcinoma (48.2%) and squamous cell carcinoma (31.3%), and patients were diagnosed with stage I-A (38.3%), stage I-B (22.7%), stage II-A (14.2%), stage II-B (11.5%), and stage III-A (13.3%). Median OS was 74 months. 1-, 3- and 5-year OS rates were 89.8% [95% confidence interval (CI) 89.5-90.0%], 71.1% (95% CI 70.7-71.6%), and 55.7% (95% CI 54.7-56.6%), respectively. The nomogram's concordance index (C-index) was 0.804 (95% CI 0.792-0.817). AJCC TNM staging demonstrated higher discrimination (C-index 0.833, 95% CI 0.821-0.840). The nomogram's individualized estimates accurately predicted survival in this patient collective, demonstrating higher discrimination in this population than in the developer's cohorts. However, the generalized survival estimates provided by traditional staging demonstrated superior predictive capability; therefore, AJCC TNM staging should remain the gold standard for the prognostication of resected NSCLC in the US. |

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 26 May 2017.
All research outputs
#6,333,293
of 22,953,506 outputs
Outputs from Annals of Surgical Oncology
#2,118
of 6,516 outputs
Outputs of similar age
#121,311
of 420,388 outputs
Outputs of similar age from Annals of Surgical Oncology
#29
of 79 outputs
Altmetric has tracked 22,953,506 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 6,516 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one has gotten more attention than average, scoring higher than 67% 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 420,388 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 79 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 63% of its contemporaries.
