Published: May 2021

Senescence is a cell stress response induced by replicative, oxidative, oncogenic, and genotoxic stresses. Tumor cells undergo senescence in response to several cancer therapeutics in vitro (Therapy-Induced Senescence, TIS), including agents utilized as neoadjuvant chemotherapy (NAC) in the treatment of invasive breast cancer. TIS has been proposed to contribute to adverse therapy outcomes including relapse. However, there is limited evidence on the induction of senescence in response to NAC in clinical cancer and its contribution to disease outcomes. In this work, the expression of three senescence-associated markers (p21CIP1, H3K9Me3 (histone H3 lysine 9 trimethylation), and Lamin B1) was investigated in breast cancer samples that developed partial or incomplete pathological response to NAC (n=37). Accordingly, 40.54% of all samples showed marker expression consistent with a senescence-like phenotype, while the remainders were either negative or inconclusive for senescence (2.70 and 56.8%, respectively). Moreover, analysis of core-needle biopsies revealed minimal changes in p21CIP1 and H3K9Me3, but significant changes in Lamin B1 expression levels following NAC, highlighting a more predictive role of Lamin B1 in senescence detection. However, our analysis did not establish an association between TIS and cancer relapse as only three patients (8.1%) with a senescence-like profile developed short-term recurrent disease. Our analysis indicates that identification of TIS in tumor samples requires large-scale transcriptomic and protein marker analyses and extended clinical follow-up. Better understanding of in vivo senescence should elucidate its contribution to therapy outcomes and pave the way for the utilization of senolytic approaches as potential adjuvant cancer therapy.
Survey of Clinician Perspectives and Practices Regarding Swallowing-Related Fatigue
Authors: Brates Danielle , Namasivayam-MacDonald Ashwini , Molfenter Sonja M.
Published: May 2021

Introduction

Fatigue is commonly identified by clinicians who evaluate and treat swallowing impairment despite a lack of research in this area. The purpose of this study was to understand the current role of swallowing-related fatigue in dysphagia evaluation with respect to (a) clinician practices, (b) perspectives, and (c) desire for resources regarding swallowing-related fatigue.

Method

A survey was conducted by licensed speech-language pathologists who evaluate and treat adult dysphagia. The survey was distributed via dysphagia-focused groups on Facebook and Special Interest Group 13. Data were analyzed descriptively and by thematic analysis for free-text response questions.

Results

Out of 426 prospective respondents, 311 completed the survey (response rate = 73.0%). While 86% of respondents agreed that fatigue may be a concern for individuals with swallowing impairment, there was wide variability in how clinicians define and evaluate swallowing-related fatigue, and the majority (62%) define fatigue in two or more ways. Explicit evaluation of fatigue was reportedly conducted by 45% of respondents during the Clinical Swallowing Evaluation, by 38% during videofluoroscopic swallowing study, and by 53% during Flexible Endoscopic Evaluation of Swallowing. The most common methods for identifying fatigue were general declines in performance over the course of the assessment. Respondents reported much more reliance on patient report during Clinical Swallowing Evaluation (41%) compared to videofluoroscopic swallowing study (7%) and fiberoptic endoscopic evaluation of swallowing (5%). Only 7% of respondents reported being aware of any standardized methods for assessing fatigue, while 97% of respondents affirmed interest in incorporating standardized methods for assessing swallow-related fatigue.

Conclusions

Our results demonstrated wide variability in how currently practicing clinicians define and evaluate swallowing-related fatigue, despite the vast majority considering fatigue to be an important factor in dysphagia evaluation. This study highlights a critical gap in the clinical evaluation of swallowing and requires significant further study to guide clinical practice.
