Preoperative magnetic resonance imaging use and oncologic outcomes in premenopausal breast cancer patients.

Breast magnetic resonance imaging (MRI) delineates disease extent sensitively in newly diagnosed breast cancer patients, but improved cancer outcomes are uncertain. Young women, for whom mammography is less sensitive, are expected to benefit from MRI-based resection. We identified 512 women aged ≤50 years, undergoing breast-conserving treatment (BCT: tumor-free resection margins and radiotherapy) during 2006-2013 through Northwestern Medicine database queries; 64.

Identifying Breast Cancer Distant Recurrences from Electronic Health Records Using Machine Learning.

Accurately identifying distant recurrences in breast cancer from the Electronic Health Records (EHR) is important for both clinical care and secondary analysis. Although multiple applications have been developed for computational phenotyping in breast cancer, distant recurrence identification still relies heavily on manual chart review. In this study, we aim to develop a model that identifies distant recurrences in breast cancer using clinical narratives and structured data from EHR.

Using natural language processing and machine learning to identify breast cancer local recurrence.

Background: Identifying local recurrences in breast cancer from patient data sets is important for clinical research and practice. Developing a model using natural language processing and machine learning to identify local recurrences in breast cancer patients can reduce the time-consuming work of a manual chart review.

Methods: We design a novel concept-based filter and a prediction model to detect local recurrences using EHRs.

Contralateral Breast Cancer Event Detection Using Nature Language Processing.

To facilitate the identification of contralateral breast cancer events for large cohort study, we proposed and implemented a new method based on features extracted from narrative text in progress notes and features from numbers of pathology reports for each side of breast cancer. Our method collects medical concepts and their combinations to detect contralateral events in progress notes. In addition, the numbers of pathology reports generated for either left or right side of breast cancer were derived as additional features.

Evaluating Mastectomy Skin Flap Necrosis in the Extended Breast Reconstruction Risk Assessment Score for 1-Year Prediction of Prosthetic Reconstruction Outcomes.

Background: Rates of mastectomy for breast cancer treatment and immediate reconstruction continue to rise. With increasing scrutiny on outcomes and patient satisfaction, there is an impetus for providers to be more deliberate in appropriate patient selection for breast reconstruction. The Breast Reconstruction Risk Assessment (BRA) Score was developed for prediction of complications after primary prosthetic breast reconstruction, focusing on calculating risk estimations for a variety of complications based on individual patient demographic and perioperative characteristics.

Percutaneous endoscopic gastrostomy site metastasis from head and neck squamous cell carcinoma: case series and literature review.

Objectives: To present our experience with head and neck squamous cell carcinoma (HNSCC) seeding of percutaneous endoscopic gastrostomy (PEG) sites and to review all reported cases to identify risk factors and develop strategies for complication avoidance.

Materials And Methods: The records of 4 patients with PEG site metastasis from HNSCC were identified from the authors' institution. Thirty-eight further cases were reviewed following a PubMed search and evaluation of references in pertinent articles.

Alphanumeric paging: a potential source of problems in patient care and communication.

Purpose: In recent years, the use of numeric paging in many medical centers has been largely replaced by 1-way alphanumeric paging. There is currently no research studying the potential for alphanumeric paging to lead to problems in communication. The purpose of this article is to determine whether the use of alphanumeric pagers may lead to potential problems in patient care and/or communication.
