Conducting Physician Engagement Research in a Pandemic: Persevering when Burnout Mitigation Is Needed Most.

We planned a pilot study on a physician engagement intervention, termed ECHO-MDA, using the Project ECHO framework. The study was approved and launched just as the COVID pandemic reached Texas. We pivoted to accommodate the realities of research in pandemic times.

Outcomes of older adults with early-stage triple-negative breast cancer (TNBC) receiving chemotherapy: a single-institution experience.

Background: Despite lower chemotherapy use in older triple-negative breast cancer (TNBC) patients, their outcomes match younger counterparts. We compared outcomes in early-stage TNBC patients by age receiving chemotherapy at a major cancer center with a national TNBC database.

Methods: Retrospective study using institutional data on stage I-III TNBC (ER/PR < 10%) women with neoadjuvant/adjuvant chemotherapy.

Short-Term Biomarker Modulation Study of Dasatinib for Estrogen Receptor-Negative Breast Cancer Chemoprevention.

Objective: Risk-reducing therapy with selective estrogen receptor (ER) modulators and aromatase inhibitors reduce breast cancer risk. However, the effects are limited to ER-positive breast cancer. Therefore, new agents with improved toxicity profiles that reduce the risk in ER-negative breast cancers are urgently needed.

Phase II Trial of Nelipepimut-S Peptide Vaccine in Women with Ductal Carcinoma In Situ.

Unlabelled: NeuVax is a vaccine comprised of the HER2-derived MHC class I peptide E75 (nelipepimut-S, NPS) combined with GM-CSF. We completed a randomized trial of preoperative vaccination with NeuVax versus GM-CSF alone in patients with ductal carcinoma in situ (DCIS). The primary objective was to evaluate for NPS-specific cytotoxic T lymphocyte (CTL) responses.

Phase I Dose Escalation Study of Topical Bexarotene in Women at High Risk for Breast Cancer.

Bexarotene is a rexinoid that has been shown to prevent mammary tumors in mouse models but oral dosing has toxicities. This phase I study evaluates topical bexarotene, as a potential chemoprevention agent, for safety and toxicity in high-risk women for breast cancer.

Associations of Dysnatremia with COVID-19 Status and Mortality.

Background: In patients without COVID-19, dysnatremia is associated with mortality. These relationships are not well established in patients with COVID-19. We tested the hypotheses that patients with COVID-19 were more likely to have dysnatremia than those without COVID-19 and that, among those with COVID-19, dysnatremia is associated with mortality.

Opioid Rotation and Conversion Ratios Used by Palliative Care Professionals: An International Survey.

The opioid rotation ratios (ORRs) and conversion ratios (CRs) used worldwide among palliative care (PC) professionals to perform opioid rotations (ORs) and route conversions may have a wide variation. We surveyed PC professionals on opioid ratios used through email to the Multinational Association of Supportive Care in Cancer's PC study group and Twitter and Facebook posts between September and November 2020. We received 370 responses from respondents from 53 countries: 276 (76%) were physicians, 46 (13%) advanced practice providers, 39 (11%) pharmacists, and 9 respondents did not report their profession.

Turnaround Times in Melanoma BRAF Testing and the Impact on the Initiation of Systemic Therapy at a Single Tertiary Care Cancer Center.

Purpose: The identification of mutations in melanoma enables targeted therapy and improves patient outcomes. Barriers to molecular testing affect the quality of care and therapeutic options.

Methods: This retrospective study mapped testing timelines in adult patients with melanoma at the Princess Margaret Cancer Centre to identify obstacles to timely reporting and its impact on the initiation of therapy.

Combination Therapy of Physical Activity and Dexamethasone for Cancer-Related Fatigue: A Phase II Randomized Double-Blind Controlled Trial.

Background: Despite the high frequency of cancer-related fatigue (CRF) and its debilitating effects on the quality of life of patients with advanced cancer, there are limited treatment options available. Treatments including physical activity (PA) or dexamethasone (Dex) improve CRF; however, they have lower adherence rates (PA) or long-term adverse effects (Dex). The aim of this study was to determine the feasibility of and preliminary results for the combination of PA and Dex in improving CRF.

Prognostic Value of Cell-Surface Vimentin-Positive CTCs in Pediatric Sarcomas.

Background: Despite advances in care, the 5 year overall survival for patients with relapsed and or metastatic sarcoma remains as low as < 35%. Currently, there are no biomarkers available to assess disease status in patients with sarcomas and as such, disease surveillance remains reliant on serial imaging which increases the risk of secondary malignancies and heightens patient anxiety.

Methods: Here, for the first time reported in the literature, we have enumerated the cell surface vimentin (CSV+) CTCs in the blood of 92 sarcoma pediatric and adolescent and young adult (AYA) patients as a possible marker of disease.

A phase II study of talimogene laherparepvec for patients with inoperable locoregional recurrence of breast cancer.

Talimogene laherparepvec (T-VEC) is an immunotherapy that generates local tumor lysis and systemic antitumor immune response. We studied the efficacy of intratumoral administration of T-VEC as monotherapy for inoperable locoregional recurrence of breast cancer. T-VEC was injected intratumorally at 10 PFU/mL on day 1 (cycle 1), 10 PFU/mL on day 22 (cycle 2), and 10 PFU/mL every 2 weeks thereafter (cycles ≥ 3).

Outcomes After Breast Radiation Therapy in a Diverse Patient Cohort With a Germline BRCA1/2 Mutation.

Purpose: BRCA1/2 pathogenic variant (PV) mutations confer radiation sensitivity preclinically, but there are limited data regarding breast cancer outcomes after radiation therapy (RT) among patients with documented BRCA1/2 PV mutations versus no PV mutations.

Methods And Materials: This retrospective cohort study included women with clinical stage I-III breast cancer who received definitive surgery and RT and underwent BRCA1/2 genetic evaluation at the The University of Texas MD Anderson Cancer Center. Rates of locoregional recurrence (LRR), disease-specific death (DSD), toxicities, and second cancers were compared by BRCA1/2 PV status.

Phase II trial of proton therapy versus photon IMRT for GBM: secondary analysis comparison of progression-free survival between RANO versus clinical assessment.

Background: This secondary image analysis of a randomized trial of proton radiotherapy (PT) versus photon intensity-modulated radiotherapy (IMRT) compares tumor progression based on clinical radiological assessment versus Response Assessment in Neuro-Oncology (RANO).

Methods: Eligible patients were enrolled in the randomized trial and had MR imaging at baseline and follow-up beyond 12 weeks from completion of radiotherapy. "Clinical progression" was based on a clinical radiology report of progression and/or change in treatment for progression.

Inflammatory breast cancer appearance at presentation is associated with overall survival.

Background: Inflammatory breast cancer (IBC) is a clinical diagnosis. Here, we examined the association of a "classic" triad of clinical signs, swollen involved breast, nipple change, and diffuse skin change, with overall survival (OS).

Method: Breast medical photographs from patients enrolled on a prospective IBC registry were scored by two independent reviewers as classic (triad above), not classic, and difficult to assign.

Management of severe hyponatremia with low-dose continuous kidney replacement therapy and peripheral D5W in an infant with acute kidney injury.

We report a 7-month-old female infant who presented with anuric acute kidney injury and severe hyponatremia (serum sodium 110 mEq/L). The patient was treated with low-dose continuous kidney replacement therapy (CKRT), that is, 85% of total clearance dose divided equally between normonatric (Na 140 mEq/L) replacement and dialysate fluids. The remaining 15% of the clearance was provided by peripheral infusion of dextrose 5% (D5W).
