ABSTRACT
BACKGROUND: One potential benefit of neoadjuvant therapy (NAT) in node-positive, estrogen receptor-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) patients is axillary downstaging to avoid axillary dissection. OBJECTIVE: The aim of this study was to evaluate axillary response to NAT with chemotherapy (NCT) or endocrine therapy (NET) and identify potential predictors of response. METHODS: A prospectively collected database was queried for node-positive, ER+, HER2- breast cancer patients treated with NAT and surgery from January 2011 to September 2020. Axillary response was categorized into pathologic complete response (pCR) versus no pCR, and was correlated to demographic and clinicopathologic parameters in a logistic regression model. RESULTS: A cohort of 176 eligible patients was identified and 178 breast cancers were included in the study. The overall axillary pCR rate was 12.3% (22/178). NCT and NET achieved response rates of 13.9% (19/137) and 7.3% (3/41), respectively (p = 0.232). A significantly higher axillary pCR rate was identified in patients with clinical stage II at diagnosis (12/60, 20%) compared with stage III (10/118, 8.4%; p = 0.03). NET patients with ypN0 were younger and were treated for a longer period of time (>6 months). Completion axillary dissection was omitted in the majority (73.7%) of NCT patients achieving axillary pCR. CONCLUSIONS: For patients with node-positive, ER+, HER2- breast cancer, a lower burden of disease at the time of diagnosis (stage II) is associated with a significantly higher axillary pCR, enabling those patients to be spared axillary dissection. Further studies are necessary to define the role of genomic profiling in predicting axillary response.
ABSTRACT
As the proportion of geriatric patients increases, so too does the incidence of geriatric trauma. Trauma centres must develop protocols to reduce the risk of complications from injuries in this specialised patient population. From a soft tissue standpoint, open wounds tend to heal slower in these patients and have a significant impact on their quality of life. In this case report, we describe our protocol for managing traumatic skin tears using a combination of traumatic skin grafts and minced expansion grafts with photographic documentation of the healing from significant wounds in an elderly patient involved in a high-energy blunt traumatic injury.
