Rideshare Intervention to Promote Access to Care and Environmental Sustainability Within Oncology Open
PURPOSE Transportation is a critical determinant of cancer care access, particularly for patients undergoing daily radiotherapy. In 2020, University of California, San Francisco Health launched a subsidized rideshare transportation program…

Leveraging Dynamic Prompting for Outcome Prediction of Cancer Patients Using Large Language Models and Electronic Health Record Notes Open
Outcome prediction from unstructured EHR notes remains challenging, especially for rare cancers with limited pre-training data. We present a dynamic prompting framework that retrieves semantically similar patient examples, constructs tailo…

Exploring the Social Media Discussion of Breast Cancer Treatment Choices: Quantitative Natural Language Processing Study Open
Background Early-stage breast cancer has the complex challenge of carrying a favorable prognosis with multiple treatment options, including breast-conserving surgery (BCS) or mastectomy. Social media is increasingly used as a source of inf…

Positive margins after mastectomy in patients with invasive lobular carcinoma of the breast: Incidence and management strategies Open
Surgical treatment of invasive lobular carcinoma (ILC) is challenging due to its diffuse growth pattern, and the positive margin rate after mastectomy is poorly described.We retrospectively determined the positive margin rate in those with…

A pilot, randomized controlled trial of tele-mentorship: a useful tool during social distancing Open
Medical mentorship is a key component to medical education. Effective mentorship increases academic research productivity, job satisfaction, and advancement of clinical skills, which translate to improved patient care.

Intensity modulated Ir-192 brachytherapy using high-Z 3D printed applicators Open
Gynecologic cancers are often asymmetric, yet current Ir-192 brachytherapy techniques provide only limited radial modulation of the dose. The shielded solutions investigated here solve this by providing the ability to modulate between high…

Long-term Outcomes of Stereotactic Body Radiotherapy for Low-Risk and Intermediate-Risk Prostate Cancer Open
In this study, stereotactic body radiotherapy for low-risk and intermediate-risk disease was associated with low rates of severe toxic events and high rates of biochemical control. These data suggest that stereotactic body radiotherapy is …

Increases in Serial Pretreatment 18F-FDG PET-CT Metrics Predict Survival in Early Stage Non-Small Cell Lung Cancer Treated With Stereotactic Ablative Radiation Therapy Open
MTGR greater than 0.04 mL/d is prognostic of death in patients with non-small cell lung cancer treated with SABR. Increasing SUVV trends, nonsignificantly, toward increased risk of recurrence and death. MTGR and SUVV may be candidate imagi…
