| Abstract |
We determined factors associated with morbidity and outcomes of a series of non-small cell lung cancer (NSCLC) patients treated with dose-escalated chemoradiotherapy at the University of Pittsburgh Lung Cancer Program. The records of 170 stage III NSCLC patients treated with definitive intent were retrospectively reviewed. All patients received four-dimensional CT simulation scan and had respiratory gating if tumor movement exceeded 5 mm. Overall survival (OS), locoregional control (LRC), and freedom from distant metastasis (FFDM) were calculated using log-rank and Cox regression analysis. For the present series of patients, median follow-up was 36.6 months, median survival 27.4 months, and the 2- and 4-year OS was 56.0 and 30.7%, respectively. The 4-year LRC and FFDM were 43.9 and 40.7%, respectively. No benefit was associated with irradiation doses above 66 Gy in OS (p = 0.586), LRC (p = 0.440), or FFDM (p = 0.230). On univariate analysis, variables associated with worse survival included: clinical stage IIIB (p = 0.037), planning target volume (PTV) over 450 cc (p < 0.001), heart V30 over 40% (p = -0.048), and esophageal mean dose over 20% (p = 0.024), V5 (p = -0.015), and V60 (p = -0.011). On multivariable analysis, PTV above 450 cc (52.2 vs. 25.3 months, p < 0.001) and esophageal V60 >20% (43.8 vs. 21.3 months, p = -0.01) were associated with lower survival. Grade 2 or higher acute lung toxicity and esophagitis were detected in 9.5 and 59.7%, respectively of patients. Grade 2 or higher acute lung toxicity was reduced if lung V5 was ≤65 (7.4 vs. 23.8%, p = 0.03). Grade 2 or higher acute esophagitis was reduced if V60 ≤ 20% (62 vs. 81.3%, p = 0.018). The use of intensity-modulated radiation therapy was more frequent in stage IIIB compared to stage IIIA patients (56.5 vs. 39.5%, p = 0.048) and was associated with a higher lung V5 and V10. The outcomes of a program of dose-escalated chemoradiotherapy for unresectable stage IIIA and IIIB NSCLC patients were consistent with other studies and showed no benefit to radiation doses above 66 Gy. Furthermore, maintaining low esophageal V60 and lung V5 were associated with lower morbidity and mortality. |

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 23 January 2017.
All research outputs
#19,947,956
of 25,377,790 outputs
Outputs from Frontiers in oncology
#9,325
of 22,420 outputs
Outputs of similar age
#305,176
of 422,539 outputs
Outputs of similar age from Frontiers in oncology
#26
of 45 outputs
Altmetric has tracked 25,377,790 research outputs across all sources so far. This one is in the 18th percentile – i.e., 18% of other outputs scored the same or lower than it.
So far Altmetric has tracked 22,420 research outputs from this source. They receive a mean Attention Score of 3.0. This one is in the 49th percentile – i.e., 49% 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 422,539 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 24th percentile – i.e., 24% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 45 others from the same source and published within six weeks on either side of this one. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
