Background: Within the multidisciplinary management of breast cancer, variations exist in reconstructive options offered and care provided. The authors evaluated plastic surgeon perspectives on important issues related to cancer reconstruction provide some insight into factors that influence these perspectives. Methods: Women diagnosed with early-stage (stages 0 II) between July 2013 September 2014 were identified through Georgia Los Angeles Surveillance, Epidemiology, End Results...

TPS613 Background: Approximately 50% of newly diagnosed breast cancers are stage 1, with the majority being ER/PR-positive, HER2-negative. Genomic assays such as Oncotype DX® have identified patients (pts) reduced risk distant metastasis and without benefit from chemotherapy added to endocrine therapy, freeing them excess toxicity. also recognized prognostic for in-breast recurrence (IBR) after BCS could similarly allow de-escalation adjuvant radiotherapy (RT). Reducing overtreatment is...

Objective Much of what is known about the significance human papillomavirus (HPV) in oropharyngeal squamous cell carcinoma derived from single‐institution retrospective studies, post hoc analyses tissue specimens clinical trials, and bank studies with a small sample size. The objective this study to investigate impact HPV on frequency presentation large, national information patients who underwent testing. Study Design Retrospective, cross‐sectional study. Methods We identified comprehensive...

Reirradiation poses a distinct therapeutic challenge owing to risks associated with exceeding normal tissue tolerances and possibly more therapeutically resistant disease biology. We report our experience reirradiation for locoregional recurrent or second primary breast cancer.Between 1999 2019, all patients cancer treated repeat breast/chest wall radiation therapy (RT) at institution were identified. Adverse events assessed using the Common Terminology Criteria Events v5.0. Fisher exact,...

Importance Little is known about regional nodal irradiation (RNI) practice patterns or rates of locoregional recurrence (LRR) with and without RNI in patients limited disease favorable biology treated modern surgical systemic therapy, including approaches that de-escalate those latter treatments. Objective To investigate how often low–recurrence score breast cancer 1 to 3 nodes involved receive RNI, incidence predictors LRR, associations between therapy disease-free survival. Design,...

BACKGROUND The authors examined racial/ethnic differences in patient perspectives regarding their breast cancer treatment experiences. METHODS A weighted random sample of women newly diagnosed with between 2013 and 2015 Los Angeles County Georgia were sent surveys 2 months after undergoing surgery (5080 women; 70% response rate). analytic was limited to patients residing (2397 women). RESULTS pattern visits different specialists before found be similar across groups. Low acculturated Latinas...

To report oncologic, physician-assessed, and patient-reported outcomes (PROs) for a group of women homogeneously treated with modern, skin-sparing multifield optimized pencil-beam scanning proton (intensity modulated therapy [IMPT]) postmastectomy radiation (PMRT).We reviewed consecutive patients who received unilateral, curative-intent, conventionally fractionated IMPT PMRT between 2015 2019. Strict constraints were applied to limit the dose skin other organs at risk. Five-year oncologic...

Over 50% of households in the United States have at least one musician-many musicians are also breast cancer survivors. This group has not been well studied, and given level fine sensory-motor skill required for musicianship, we hypothesized that experience unique manifestations treatment toxicities. A nine-item Musical Toxicity Questionnaire (MTQ) was distributed to patients who had consented participate Mayo Clinic Breast Cancer Registry. The MTQ screened participants by asking if they...

Abstract Background In breast cancer patients treated with pencil‐beam scanning proton therapy (PBS), the increased linear energy transfer (LET) near end of range can affect nearby ribs. This may associate a higher risk rib fractures. Purpose To study effect LET on fracture in PBS using novel tool dose‐LET volume histogram (DLVH). Methods From prospective registry post‐mastectomy to chest wall and regional lymph nodes for between 2015 2020, we retrospectively identified cases detected after...

The Health Care Climate Questionnaire measures patient perceptions of their clinician's autonomy supportive communication. We sought to evaluate the psychometric properties a modified brief version (mHCCQ) adapted for breast cancer patients.We surveyed 235 women aged 20-79 diagnosed with within previous 18 months at two specialty centers using print questionnaire. Patients completed mHCCQ surgeon, medical oncologist, and radiation oncologist separately, as well overall treatment experience....
