| Abstract |
Inflammatory breast cancer (IBC) is a rare and aggressive disease treated with multimodality therapy: preoperative systemic therapy (PST) followed by modified radical mastectomy (MRM), chest wall and regional nodal radiotherapy, and adjuvant biologic therapy and/or endocrine therapy when appropriate. In non-IBC, the degree of pathologic response to PST has been shown to correlate with time to recurrence (TTR) and overall survival (OS). We sought to determine if pathologic response correlates with oncologic outcomes of IBC patients. Following review of IBC patients' records (1997-2014), we identified 258 stage III IBC patients; 181 received PST followed by MRM and radiotherapy and were subsequently analyzed. Pathologic complete response (pCR) to PST, hormone receptor and human epidermal growth factor receptor 2 (HER2) status, grade, and histology were evaluated as predictors of TTR and OS by Cox model. Overall, 95/181 (52%) patients experienced recurrence; 93/95 (98%) were distant metastases (median TTR 3.2 years). Seventy-three patients (40%) died (median OS 6.9 years). pCR was associated with improved TTR (hazard ratio [HR] 0.20, 95% confidence interval [CI] 0.09-0.46, p < 0.01, univariate; HR 0.17, 95% CI 0.07-0.41, p < 0.0001, multivariate) and improved OS (HR 0.26, 95% CI 0.11-0.65, p < 0.01, univariate). In patients with pCR, grade III (HR 1.91, 95% CI 1.16-3.13, p = 0.01), and triple-negative phenotype (HR 3.54, 95% CI 1.79-6.98, p = 0.0003) were associated with shorter TTR, while residual ductal carcinoma in situ was not (HR 0.85, 95% CI 0.53-1.35, p = 0.48, multivariate). In stage III IBC, pCR was associated with prognosis, further influenced by grade, hormone receptor, and HER2 status. Investigating mechanisms that contribute to better response to PST could help improve oncologic outcomes in IBC. |

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 17 August 2017.
All research outputs
#18,567,744
of 22,997,544 outputs
Outputs from Annals of Surgical Oncology
#5,036
of 6,529 outputs
Outputs of similar age
#241,084
of 316,075 outputs
Outputs of similar age from Annals of Surgical Oncology
#50
of 66 outputs
Altmetric has tracked 22,997,544 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,529 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.4. This one is in the 15th percentile – i.e., 15% 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 316,075 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 66 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
