Assessing nearly 14,000 women from a contemporary United States database, this is the largest known study examining the relationship between response to NC and molecular subtype. Women with luminal A disease are the least likely to undergo pCR, with the highest rates in Her2 disease. Degree of response is associated with OS, especially in luminal B, Her2, and TN patients. Despite the comparatively higher likelihood of achieving pCR in TN cases, this subgroup may still experience a survival detriment, which has implications for an ongoing national randomized trial.

Purpose Metaplastic breast cancer (MBC) is a rare, aggressive variant of breast cancer that has been associated with poor clinical outcomes, as has triple-negative breast (TNBC) cancer. Limited studies compare the clinical characteristics and prognosis of MBC to TNBC. This study uses a large, contemporary US cancer database to compare clinical characteristics and survival outcomes for patients with MBC to those with TNBC. Methods The National Cancer Database was queried for women with cT1-4N1-3M0 MBC or TNBC diagnosed between 2004 and 2013 and treated with definitive surgery. Chi-squared analysis was performed to determine differences between the cohorts. Kaplan-Meier curves compared overall survival (OS), and Cox regression determined patient factors associated with OS. Results Altogether, 55,847 patients met the inclusion criteria; 50,705 (90.8%) had TNBC and 5,142 (9.2%) had MBC. Most patients had no comorbid conditions (82%), N0 disease (71%), poorly differentiated histology (77%), received chemotherapy (87%), and received radiation therapy (60%). Amongst all patients, patients with TNBC disease were observed to have greater OS than those with MBC (5-year OS 72.0% vs 55.8%, p < 0.001). The greater observed OS for patients with TNBC persisted when controlling for stage and when comparing propensity score matched cohorts. On Cox regression, lower age, T1 status, N0 status, chemotherapy, TNBC disease, and radiation therapy (RT) were associated with improved OS. Conclusions MBC had an association with poorer OS compared to TNBC, while RT and chemotherapy receipt were associated with improved OS for patients regardless of stage. Further studies are needed to corroborate the conclusions herein.

Publication of your research represents the culmination of your scientific activities. The key to getting manuscripts accepted is to make them understandable and informative so that your colleagues will read and benefit from them. We describe key criteria for acceptance of manuscripts and outline a multi-step process for writing the manuscript. The likelihood that a manuscript will be accepted by a major journal is significantly increased if the manuscript is written in polished and fluent scientific English. Although scientific quality is the most important consideration, clear and concise writing often makes the difference between acceptance and rejection. As with any skill, efficient writing of high-quality manuscripts comes with experience and repetition. It is very uncommon for a manuscript to be accepted as submitted to a journal. Thoughtful and respectful responses to the journal reviewers' comments are critical. Success in scientific writing, as in surgery, is dependent on effort, repetition, and commitment. The transfer of knowledge through a well-written publication in a high-quality medical journal will have an impact not only in your own institution and country, but also throughout the world.Publication of a scientific manuscript is the ultimate and arguably one of the most important components of research.1 Through publication of a scientific manuscript, your knowledge and experience become citable science in the form of novel information transmitted to physicians and scientists for current and future generations. Writing manuscripts can be a rewarding and satisfying creative process, and publication of manuscripts confers substantial benefits to academic surgeons.3 Publications in high-quality journals lend credibility to your research (due to the rigorous peer review of high-quality journals and the intense competition for the limited publication space in such journals) and are highly valued evidence of scholarship by promotion and tenure committees. A strong track record of publications carries significant influence in the allocation of grants.For trainees and surgeons early in their careers, writing manuscripts can be a valuable learning experience. As with any skill, efficient writing of high-quality manuscripts comes with experience and repetition. In this article, we offer suggestions to speed the learning process for trainees and early-career surgeons. This advice is relevant not only for manuscripts submitted to Annals of Surgical Oncology, for which most of us serve as editorial leaders, but also for clinical research manuscripts in general.

The changing expression levels of ocular proteins in response to systemic disease has been well established in literature. In this study, we examined the ocular proteome to identify protein biomarkers with altered expression levels in women diagnosed with breast cancer. Tear samples were collected from 273 participants using Schirmer strip collection methods. Following protein elution, proteome wide trypsin digestion with Liquid chromatography/tandem mass spectrometry (LC-MS/MS) was used to identify potential protein biomarkers with altered expression levels in breast cancer patients. Selected biomarkers were further validated by enzyme linked immunosorbent assay (ELISA). A total of 102 individual tear samples (51 breast cancer, 51 control) were analyzed by LC-MS/MS which identified 301 proteins. Spectral intensities between the groups were compared and 14 significant proteins (p-value <0.05) were identified as potential biomarkers in breast cancer patients. Three biomarkers, S100A8 (p-value = 0.0069, 7.8-fold increase), S100A9 (p-value = 0.0048, 10.2-fold increase), and Galectin-3 binding protein (p-value = 0.01, 3.0-fold increase) with an increased expression in breast cancer patients were selected for validation using ELISA. Validation by ELISA was conducted using 171 individual tear samples (75 Breast Cancer and 96 Control). Similar to the observed LC-MS/MS results, S100A8 (p-value <0.0001) and S100A9 (p-value <0.0001) showed significantly higher expression in breast cancer patients. However, galectin-3 binding protein had increased expression in the control group. Our results provide further support for using tear proteins to detect non-ocular systemic diseases such as breast cancer. Our work provides crucial details to support the continued evaluation of tear samples in the screening and diagnosis of breast cancer and paves the way for future evaluation of the tear proteome for screening and diagnosis of systemic diseases.
