A randomized phase 2 trial of nivolumab, gemcitabine, and cisplatin or nivolumab and ipilimumab in previously untreated advanced biliary cancer: BilT-01.

BACKGROUND: Gemcitabine and cisplatin has limited benefit as treatment for advanced biliary tract cancer (BTC). The addition of an anti-programmed death receptor (PD-1)/PD-ligand (L1) antibody to either systemic chemotherapy or anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA4) antibody has shown benefit in multiple solid tumors. METHODS: In this phase 2 trial, patients 18 years or older with advanced BTC without prior systemic therapy and Eastern Cooperative Oncology Group Performance Status 0-1 were randomized across six academic centers. Patients in Arm A received nivolumab (360 mg) on day 1 along with gemcitabine and cisplatin on days 1 and 8 every 3 weeks for 6 months followed by nivolumab (240 mg) every 2 weeks. Patients in Arm B received nivolumab (240 mg) every 2 weeks and ipilimumab (1 mg/kg) every 6 weeks. RESULTS: Of 75 randomized patients, 68 received therapy (Arm A = 35, Arm B = 33); 51.5% women with a median age of 62.5 years. The observed primary outcome of 6-month progression-free survival (PFS) rates in the evaluable population was 59.4% in Arm A and 21.2% in Arm B. The median PFS and overall survival (OS) in Arm A were 6.6 and 10.6 months, and in Arm B 3.9 and 8.2 months, respectively, in patients who received any treatment. The most common treatment-related grade 3 or higher hematologic adverse event was neutropenia in 34.3% (Arm A) and nonhematologic adverse events were fatigue (8.6% Arm A) and elevated transaminases (9.1% Arm B). CONCLUSIONS: The addition of nivolumab to chemotherapy or ipilimumab did not improve 6-month PFS. Although median OS was less than 12 months in both arms, the high OS rate at 2 years in Arm A suggests benefit in a small cohort of patients.

Carfilzomib, lenalidomide, and dexamethasone plus transplant in newly diagnosed multiple myeloma.

In this phase 2 multicenter study, we evaluated the incorporation of autologous stem cell transplantation (ASCT) into a carfilzomib-lenalidomide-dexamethasone (KRd) regimen for patients with newly diagnosed multiple myeloma (NDMM). Transplant-eligible patients with NDMM received 4 cycles of KRd induction, ASCT, 4 cycles of KRd consolidation, and 10 cycles of KRd maintenance. The primary end point was rate of stringent complete response (sCR) after 8 cycles of KRd with a predefined threshold of ≥50% to support further study. Seventy-six patients were enrolled with a median age of 59 years (range, 40-76 years), and 35.5% had high-risk cytogenetics. The primary end point was met, with an sCR rate of 60% after 8 cycles. Depth of response improved over time. On intent-to-treat (ITT), the sCR rate reached 76%. The rate of minimal residual disease (MRD) negativity using modified ITT was 70% according to next-generation sequencing (<10-5 sensitivity). After median follow-up of 56 months, 5-year progression-free survival (PFS) and overall survival (OS) rates were 72% and 84% for ITT, 85% and 91% for MRD-negative patients, and 57% and 72% for patients with high-risk cytogenetics. For high-risk patients who were MRD negative, 5-year rates were 77% and 81%. Grade 3 to 4 adverse events included neutropenia (34%), lymphopenia (32%), infection (22%), and cardiac events (3%). There was no grade 3 to 4 peripheral neuropathy. Patients with NDMM treated with KRd with ASCT achieved high rates of sCR and MRD-negative disease at the end of KRd consolidation. Extended KRd maintenance after consolidation contributed to deepening of responses and likely to prolonged PFS and OS. Safety and tolerability were manageable. This trial was registered at www.clinicaltrials.gov as #NCT01816971.

Public Attitudes Regarding Hospitals and Physicians Encouraging Donations From Grateful Patients.

Importance: Philanthropy is an increasingly important source of support for health care institutions. There is little empirical evidence to inform ethical guidelines. Objective: To assess public attitudes regarding specific practices used by health care institutions to encourage philanthropic donations from grateful patients. Design, Setting, and Participants: Using the Ipsos KnowledgePanel, a probability-based sample representative of the US population, a survey solicited opinions from a primary cohort representing the general population and 3 supplemental cohorts (with high income, cancer, and with heart disease, respectively). Exposures: Web-based questionnaire. Main Outcomes and Measures: Descriptive analyses (with percentages weighted to make the sample demographically representative of the US population) evaluated respondents' attitudes regarding the acceptability of strategies hospitals may use to identify, solicit, and thank donors; perceptions of the effect of physicians discussing donations with their patients; and opinions regarding gift use and stewardship. Results: Of 831 individuals targeted for the general population sample, 513 (62%) completed surveys, of whom 246 (48.0%) were women and 345 (67.3%) non-Hispanic white. In the weighted sample, 47.0% (95% CI, 42.3%-51.7%) responded that physicians giving patient names to hospital fundraising staff after asking patients' permission was definitely or probably acceptable; 8.5% (95% CI, 5.7%-11.2%) endorsed referring without asking permission. Of the participants, 79.5% (95% CI, 75.6%-83.4%) reported it acceptable for physicians to talk to patients about donating if patients have brought it up; 14.2% (95% CI, 10.9%-17.6%) reported it acceptable when patients have not brought it up; 9.9% (95% CI, 7.1%-12.8%) accepted hospital development staff performing wealth screening using publicly available data to identify patients capable of large donations. Of the participants, 83.2% (95% CI, 79.5%-86.9%) agreed that physicians talking with their patients about donating may interfere with the patient-physician relationship. For a hypothetical patient who donated $1 million, 50.1% (95% CI, 45.4%-54.7%) indicated it would be acceptable for the hospital to show thanks by providing nicer hospital rooms, 26.0% (95% CI, 21.9%-30.1%) by providing expedited appointments, and 19.8% (95% CI, 16.1%-23.5%) by providing physicians' cell phone numbers. Conclusions and Relevance: In this survey study of participants drawn from the general US population, a substantial proportion did not endorse legally allowable approaches for identifying, engaging, and thanking patient-donors.

This study assesses career satisfaction, discrepancies between ideal and expected careers, and likelihood of leaving current positions among former K awardees.

Patient views and correlates of radiotherapy omission in a population-based sample of older women with favorable-prognosis breast cancer.

BACKGROUND: The omission of radiotherapy (RT) after lumpectomy is a reasonable option for many older women with favorable-prognosis breast cancer. In the current study, we sought to evaluate patient perspectives regarding decision making about RT. METHODS: Women aged 65 to 79 years with AJCC 7th edition stage I and II breast cancer who were reported to the Georgia and Los Angeles County Surveillance, Epidemiology, and End Results registries were surveyed (response rate, 70%) regarding RT decisions, the rationale for omitting RT, decision-making values, and understanding of disease recurrence risk. We also surveyed their corresponding surgeons (response rate, 77%). Patient characteristics associated with the omission of RT were evaluated using multilevel, multivariable logistic regression, accounting for patient clustering within surgeons. RESULTS: Of 999 patients, 135 omitted RT (14%). Older age, lower tumor grade, and having estrogen receptor-positive disease each were found to be strongly associated with omission of RT in multivariable analyses, whereas the number of comorbidities was not. Non-English speakers were more likely to omit RT (adjusted odds ratio, 5.9; 95% confidence interval, 1.4-24.5). The most commonly reported reasons for RT omission were that a physician advised the patient that it was not needed (54% of patients who omitted RT) and patient choice (41%). Risk of local disease recurrence was overestimated by all patients: by approximately 2-fold among those who omitted RT and by approximately 8-fold among those who received RT. The risk of distant disease recurrence was overestimated by approximately 3-fold on average. CONCLUSIONS: To some extent, decisions regarding RT omission are appropriately influenced by patient age, tumor grade, and estrogen receptor status, but do not appear to be optimally tailored according to competing comorbidities. Many women who are candidates for RT omission overestimate their risk of disease recurrence. Cancer 2018;124:2714-2723. © 2018 American Cancer Society.

The association between patient attitudes and values and the strength of consideration for contralateral prophylactic mastectomy in a population-based sample of breast cancer patients.

BACKGROUND: Little is known about how the individual decision styles and values of breast cancer patients at the time of treatment decision making are associated with the consideration of different treatment options and specifically with the consideration of contralateral prophylactic mastectomy (CPM). METHODS: Newly diagnosed patients with early-stage breast cancer who were treated in 2013-2014 were identified through the Surveillance, Epidemiology, and End Results registries of Los Angeles and Georgia and were surveyed approximately 7 months after surgery (n = 2578; response rate, 71%). The primary outcome was the consideration of CPM (strong vs less strong). The association between patients' values and decision styles and strong consideration was assessed with multivariate logistic regression. RESULTS: Approximately one-quarter of women (25%) reported strong/very strong consideration of CPM, and another 29% considered it moderately/weakly. Decision styles, including a rational-intuitive approach to decision making, varied. The factors most valued by women at the time of treatment decision making were as follows: avoiding worry about recurrence (82%) and reducing the need for more surgery (73%). In a multivariate analysis, patients who preferred to make their own decisions, those who valued avoiding worry about recurrence, and those who valued avoiding radiation significantly more often strongly considered CPM (P < .05), whereas those who reported being more logical and those who valued keeping their breast did so less often. CONCLUSIONS: Many patients considered CPM, and the consideration was associated with both decision styles and values. The variability in decision styles and values observed in this study suggests that formally evaluating these characteristics at or before the initial treatment encounter could provide an opportunity for improving patient clinician discussions.

Recurrence risk perception and quality of life following treatment of breast cancer.

PURPOSE: Little is known about different ways of assessing risk of distant recurrence following cancer treatment (e.g., numeric or descriptive). We sought to evaluate the association between overestimation of risk of distant recurrence of breast cancer and key patient-reported outcomes, including quality of life and worry. METHODS: We surveyed a weighted random sample of newly diagnosed patients with early-stage breast cancer identified through SEER registries of Los Angeles County & Georgia (2013-14) ~2 months after surgery (N = 2578, RR = 71%). Actual 10-year risk of distant recurrence after treatment was based on clinical factors for women with DCIS & low-risk invasive cancer (Stg 1A, ER+, HER2-, Gr 1-2). Women reported perceptions of their risk numerically (0-100%), with values ≥10% for DCIS & ≥20% for invasive considered overestimates. Perceptions of "moderate, high or very high" risk were considered descriptive overestimates. In our analytic sample (N = 927), we assessed factors correlated with both types of overestimation and report multivariable associations between overestimation and QoL (PROMIS physical & mental health) and frequent worry. RESULTS: 30.4% of women substantially overestimated their risk of distant recurrence numerically and 14.7% descriptively. Few factors other than family history were significantly associated with either type of overestimation. Both types of overestimation were significantly associated with frequent worry, and lower QoL. CONCLUSIONS: Ensuring understanding of systemic recurrence risk, particularly among patients with favorable prognosis, is important. Better risk communication by clinicians may translate to better risk comprehension among patients and to improvements in QoL.

Surgeon and Radiation Oncologist Views on Omission of Adjuvant Radiotherapy for Older Women with Early-Stage Breast Cancer.

PURPOSE: Although clinical trials have shown no survival advantage and only a modest improvement in local control from adjuvant radiotherapy after lumpectomy in older women with stage I, estrogen receptor-positive (ER+) breast cancer, radiotherapy is commonly administered, raising concerns about overtreatment. Therefore, we sought to evaluate physician views on omission of radiotherapy in older women with favorable prognosis breast cancer. METHODS: We surveyed a national sample of 713 radiation oncologists and 879 surgeons. Of these, 1504 were eligible and 825 responded (55%). We assessed responses to clinical scenarios, knowledge of pertinent risk information, and correlates of views on radiotherapy omission. RESULTS: Omission of radiotherapy in patients age ≥70 years with stage I, ER+ breast cancer, treated with lumpectomy and endocrine therapy, was felt to be unreasonable by 40% of surgeons and 20% of radiation oncologists. Many surgeons (29%) and radiation oncologists (10%) erroneously associated radiotherapy in older women with improvement in survival. Similarly, 32% of surgeons and 19% of radiation oncologists tended to substantially overestimate the risk of locoregional recurrence in older women with omission of RT. In a scenario with an 81-year-old with multiple comorbidities, 31% of surgeons and 35% of radiation oncologists would still recommend radiotherapy. CONCLUSIONS: Many radiation oncologists and surgeons continue to consider omission of radiotherapy as substandard therapy and overestimate the benefits of radiotherapy. Surgeons, in addition to radiation oncologists, may have an opportunity to play a pivotal role in reducing overuse of aggressive care in this setting.

A phase I trial of cabozantinib and gemcitabine in advanced pancreatic cancer.

Background Cabozantinib and gemcitabine improve tumor control in pancreatic ductal adenocarcinoma (PDAC) in preclinical models through c-Met inhibition. We sought to determine the maximum tolerated dose (MTD) of this combination in patients with advanced PDAC. Methods Patients with ≤1 prior treatment and adequate performance status were eligible. Cabozantinib was given orally once daily, beginning day (-)7 and continued with gemcitabine given intravenously on days 1, 8, and 15 every 28 days. Dose level was assigned using Time to Event Continual Reassessment Method (TITE-CRM). Primary endpoint was MTD, defined as the highest dose level at which ≤25 % of patients incurred a dose-limiting toxicity (DLT). Secondary endpoints included response rate, progression-free survival (PFS), overall survival (OS) and urinary biomarker assessment. Results Twelve patients were enrolled and treated with 10 patients evaluable for DLT. The probability of DLT was >25 % for all dose levels tested, and thus an MTD was not determined. DLTs included grade 3 ALT/AST elevations and thrombocytopenia. Three patients had partial responses, but each discontinued therapy due to toxicity. Median PFS and OS were 4.7 (95 % CI: 1.4-9.7) and 10.1 months (95 % CI: 3.6-20.6). Exploratory biomarker analysis showed correlation of c-Met and VEGF levels with response. Conclusions An MTD for the combination was not established. Cabozantinib and gemcitabine appear impractical for further development due to DLT at low doses and continuing toxicities with ongoing therapy. Acknowledging the small sample size, responses were seen suggesting further investigation of c-Met inhibition in PDAC may be warranted.

Differences between Breast Conservation-Eligible Patients and Unilateral Mastectomy Patients in Choosing Contralateral Prophylactic Mastectomies.

There has been an increasing use of bilateral mastectomy (BM) for breast cancer. We sought to examine our trends among breast conservation (BCT) candidates and women recommended for unilateral mastectomy (UM). Our prospective breast cancer database was queried for women with a first-time, unilateral breast cancer. Patient and histologic factors and surgical treatment, including reconstruction, were evaluated. A detailed chart review was performed among patients from two representative time periods as to the reasons the patient underwent mastectomy. We identified 3,892 women between 2000 and 2012 of whom 60% underwent BCT, 1092 (28%) had UM and 12% underwent BM. BM rose from 4% in 2000 to a high of 19% in 2011, increasing around 2002 for women <40. BCT was less likely with decreasing age (p < 0.0001), lobular histology (p < 0.0001), higher stage (p < 0.0001) and decreasing BMI (p < 0.0001). Among mastectomy patients, contralateral mastectomy was associated with decreasing age (p < 0.0001), Caucasian race (p < 0.0001), and lower stage (p = 0.005). Over time, indications for mastectomy decreased while patients deemed BCT-eligible opting for UM or BM increased dramatically. Increases in the use of BM are in large part among women who were otherwise BCT-eligible. Factors associated with BM use are different for BCT-eligible patients and those recommended for UM. A better understanding of the factors driving individual patient choices is needed.

Gender differences in resources and negotiation among highly motivated physician-scientists.

BACKGROUND: Resources, including space, equipment, funding, personnel, and protected time, are essential in academic medical careers. Negotiation often plays a key role in the distribution of these resources. OBJECTIVE: This study explored gender differences in resources, negotiation behaviors, and negotiation outcomes in a sample of career development awardees. DESIGN: Postal survey of a cohort of 1,708 clinician-researchers with responses from 1,275 (75 % response rate). PARTICIPANTS: Researchers who received NIH K08 or K23 awards between 2006 and 2009. MAIN MEASURES: We analyzed gender differences in resources, negotiation behaviors, and negotiation outcomes, using regression models adjusted for race, K award type, K award year, degree, academic rank, specialty, and institutional funding. KEY RESULTS: Over one-fifth of respondents reported inadequate access to research space and one-third had asked for increased space or equipment. Perceived adequacy of these physical resources did not differ significantly by gender, but a higher proportion of women reported inadequate access to grants administrators (34.8 %) and statistical support (49.9 %) than men (26.9 %; p = 0.002 and 43.4 %; p = 0.025, respectively). Women were more likely to have asked for reduction in clinical hours (24.1 % vs. 19.3 %; p = 0.02) and to have raised concerns about unfair treatment (50.2 % vs. 38.2 %; p < 0.001). Overall, 42.9 % of women and 35.9 % of men asked for a raise in the two years preceding the survey (p = 0.09), and among those who had asked for increased resources, the likelihood that the request was granted did not differ significantly by gender. CONCLUSION: Many career development award recipients report resource needs and negotiate for increased resources. Gender differences in perceived access to research support personnel exist even in this select cohort of K awardees. Institutions should provide appropriate training in negotiation and ensure adequate and equitable distribution of resources to promote academic success.

Gender differences in time spent on parenting and domestic responsibilities by high-achieving young physician-researchers.

BACKGROUND: Female physician-researchers do not achieve career success at the same rate as men. Differences in nonprofessional responsibilities may partially explain this gap. OBJECTIVE: To investigate the division of domestic labor by gender in a motivated group of early-career physician-researchers. DESIGN: Nationwide postal survey between 2010 and 2011. SETTING: United States. PARTICIPANTS: Physician recipients of National Institutes of Health K08 or K23 awards between 2006 and 2009 with active academic affiliation at the time of the survey. MEASUREMENTS: Time spent on parenting and domestic tasks was determined through self-report. Among married or partnered respondents with children, a linear regression model of time spent on domestic activities was constructed considering age, gender, race, specialty, MD or MD/PhD status, age of youngest child, number of children, work hours, K award type, and spousal employment. RESULTS: A 74% response rate was achieved, and 1049 respondents were academic physicians. Women were more likely than men to have spouses or domestic partners who were employed full-time (85.6% [95% CI, 82.7% to 89.2%] vs. 44.9% [CI, 40.8% to 49.8%]). Among married or partnered respondents with children, after adjustment for work hours, spousal employment, and other factors, women spent 8.5 more hours per week on domestic activities. In the subgroup with spouses or domestic partners who were employed full-time, women were more likely to take time off during disruptions of usual child care arrangements than men (42.6% [CI, 36.6% to 49.0%] vs. 12.4% [CI, 5.4% to 19.5%]). LIMITATIONS: Analyses relied on self-reported data. The study design did not enable investigation of the relationship between domestic activities and professional success. CONCLUSION: In this sample of career-oriented professionals, gender differences in domestic activities existed among those with children. Most men's spouses or domestic partners were not employed full-time, which contrasted sharply with the experiences of women. PRIMARY FUNDING SOURCE: National Institutes of Health.

Psychometric properties of a brief measure of autonomy support in breast cancer patients.

BACKGROUND: The Health Care Climate Questionnaire measures patient perceptions of their clinician's autonomy supportive communication. We sought to evaluate the psychometric properties of a modified brief version of the Health Care Climate Questionnaire (mHCCQ) adapted for breast cancer patients. METHODS: We surveyed 235 women aged 20-79 diagnosed with breast cancer within the previous 18 months at two cancer specialty centers using a print questionnaire. Patients completed the mHCCQ for their surgeon, medical oncologist, and radiation oncologist separately, as well as the overall treatment experience. Exploratory factor analysis (EFA) using principal components was used to explore the factor structure. RESULTS: One hundred sixty out of 235 (68.1%) women completed the survey. Mean age was 57 years and time since diagnosis was 12.6 months. For surgeon, medical oncologist, and radiation oncologist ratings separately, as well as overall treatment, women rated 6 dimensions of perceived physician autonomy support. Exploratory factor analysis indicated a single factor solution for each clinician type and for the overall experience. Further, all six items were retained in each clinician subscore. Internal consistency was 0.93, 0.94, 0.97, and 0.92 for the overall, surgeon, medical oncologist, and radiation oncologist scales, respectively. Hierarchical factor analysis demonstrated that a summary score of the overall treatment experience accounts for only 52% of the total variance observed in ratings of autonomy support for the three provider types. CONCLUSIONS: These results describe the first use of the mHCCQ in cancer patients. Ratings of the overall treatment experience account for only half of the variance in ratings of autonomy support, suggesting that patients perceive and report differences in communication across provider types. Future research is needed to evaluate the relationship between physician communication practices and the quality of decision making, as well as other outcomes among cancer patients.

A phase 1/2 study of carfilzomib in combination with lenalidomide and low-dose dexamethasone as a frontline treatment for multiple myeloma.

This phase 1/2 study in patients with newly diagnosed multiple myeloma (N = 53) assessed CRd--carfilzomib (20, 27, or 36 mg/m2, days 1, 2, 8, 9, 15, 16 and 1, 2, 15, 16 after cycle 8), lenalidomide (25 mg/d, days 1-21), and weekly dexamethasone (40/20 mg cycles 1-4/5+)--in 28-day cycles. After cycle 4, transplantation-eligible candidates underwent stem cell collection (SCC) then continued CRd with the option of transplantation. The maximum planned dose level (carfilzomib 36 mg/m2) was expanded in phase 2 (n = 36). Thirty-five patients underwent SCC, 7 proceeded to transplantation, and the remainder resumed CRd. Grade 3/4 toxicities included hypophosphatemia (25%), hyperglycemia (23%), anemia (21%), thrombocytopenia (17%), and neutropenia (17%); peripheral neuropathy was limited to grade 1/2 (23%). Most patients did not require dose modifications. After a median of 12 cycles (range, 1-25), 62% (N = 53) achieved at least near-complete response (CR) and 42% stringent CR. Responses were rapid and improved during treatment. In 36 patients completing 8 or more cycles, 78% reached at least near CR and 61% stringent CR. With median follow-up of 13 months (range, 4-25 months), 24-month progression-free survival estimate was 92%. CRd was well tolerated with exceptional response rates. This study is registered at http://www.clinicaltrials.gov as NCT01029054.

National science foundation grant awardees' perspectives on Article X and sexual harassment in science.

Federal scientific agencies seek to make an impact on the continued prevalence of sexual harassment in the scientific academic community beyond institutional self-regulation. The National Science Foundation's Article X, released in 2018, is one of the most significant and ambitious federal policy initiatives to address sexual harassment. The present article presents the results of the first study to examine scientists' knowledge and attitudes about this important recent policy. We found, although overall knowledge about Article X was fairly low, the majority of participants responded positively to it. Crucially, impressions of the policy varied based on past experience and demographic factors. Individuals who had experienced harassment in the past year were less likely to believe the policy would help reduce sexual harassment in the sciences compared to those who had not experienced harassment (OR = 0.47, 95% CI:0.23-0.97, p = .034) and had greater odds of endorsing that the policy failed to go far enough (OR = 2.77, 95% CI:1.15-6.66, p = .023). Associations between demographic factors and views of the policy were less pronounced, but it is notable that, compared to their White counterparts, Black participants were more likely to believe the policy went too far (OR = 5.87, 95% CI:1.04-33.17, p = .045). Additionally, concerns were raised about the institutional enforcement of these policies and the existence of sufficient protections for survivors. Our work has implications for NSF's continued evaluation of the efficacy of this program as well as for other federal agencies implementing or considering similar policies.

Burnout Among Mid-Career Academic Medical Faculty.

Importance: Studies reveal that most physicians report symptoms of burnout. Less is known about burnout in mid-career medical faculty specifically. Objective: To characterize burnout and its risk factors, particularly differences by gender, among mid-career medical faculty. Design, Setting, and Participants: Between August 2021 and August 2022, a survey was sent to 1430 individuals who received new National Institutes of Health K08 and K23 career development awards from 2006 to 2009. Data were analyzed between June and October 2023. Main Outcomes and Measures: Personal and work-related burnout as evaluated using the Copenhagen Burnout Inventory (CBI). The CBI score ranges from 0 to 100, with a score of 50 or higher indicating a high degree of burnout. Multivariable models were used to investigate associations between burnout and participant characteristics, including race and ethnicity, sexual orientation and gender identity, academic rank, work climate, experiences of workplace sexual harassment, sleep hours, work and domestic caregiving time, and time allocation changes in work and domestic work hours compared with before the COVID-19 pandemic. Work climate was evaluated by a general climate elements scale assessing elements such as friendliness, respect, and collegiality, and a diversity, equity, and inclusion climate elements scale assessing elements such as homogeneity, sexism, and homophobia; higher scores indicated a more favorable view of the climate. Results: In all, 1430 surveys were sent, 926 candidates responded (65% response rate), and the analytic cohort was limited to the 841 respondents who were still in academic medicine (50.7% men). Burnout was significantly more common for women than men (mean [SD] CBI personal scores, 46.6 [19.4] vs 37.5 [17.2]; P < .001; mean [SD] CBI work-related scores, 43.7 [20.4] vs 34.6 [19.7]; P < .001). In multivariable models, personal burnout was significantly more likely for women (adjusted odds ratio [AOR], 2.29 [95% CI, 1.54-3.41]; P < .001) and with more weekly hours of patient care (AOR, 1.07 [95% CI, 1.00-1.15] for each 5-hour increase; P = .04). Personal burnout was less likely with more nightly sleep hours (AOR, 0.68 [95% CI, 0.56-0.81] for each 1-hour increase; P < .001) and with an improved general work climate rating (AOR, 0.64 [95% CI, 0.48-0.85] for each 1-point increase in general work climate scale score; P = .002). Work-related burnout was also significantly more likely for women than men (AOR, 1.77 [95% CI, 1.17-2.69]; P = .007). Greater work-related burnout was associated with an increase of 8 or more work hours per week compared with before the COVID-19 pandemic (AOR, 1.87 [95% CI, 1.13-3.08]; P = .01), more weekly hours of patient care (AOR, 1.11 [95% CI, 1.03-1.19] for each 5-hour increase; P = .007), and a workplace sexual harassment experience in the past 2 years (AOR, 1.71 [95% CI, 1.11-2.62]; P = .01). Work-related burnout was significantly less likely with more nightly sleep hours (AOR, 0.80 [95% CI, 0.66-0.96] for each 1-hour increase; P = .02) and with an improved general work climate rating (AOR, 0.49; [95% CI, 0.36-0.65] for each 1-point increase in general work climate scale score; P < .001). Conclusions and Relevance: This survey study of K grant awardees revealed substantial rates of burnout among mid-career medical faculty, and burnout rates differed by gender. Evidence-based interventions are needed to realize the benefits of workforce diversity and vitality.

Factors Associated With Cardiac Radiation Dose Reduction After Hypofractionated Radiation Therapy for Localized, Left-Sided Breast Cancer in a Large Statewide Quality Consortium.

PURPOSE: Limiting cardiac radiation dose is important for minimizing long-term cardiac toxicity in patients with left-sided early-stage breast cancer. METHODS AND MATERIALS: Prospectively collected dosimetric data were analyzed for patients undergoing moderately hypofractionated radiation therapy to the left breast within the Michigan Radiation Oncology Quality Consortium from 2016 to 2022. The mean heart dose (MHD) goal was progressively tightened from ≤2 Gy in 2016 to MHD ≤ 1.2 Gy in 2018. In 2021, a planning target volume (PTV) coverage goal was added, and the goal MHD was reduced to ≤1 Gy. Multivariate logistic regression models were developed to assess for covariates associated with meeting the MHD goals in 2016 to 2020 and the combined MHD/PTV coverage goal in 2021 to 2022. RESULTS: In total, 4165 patients were analyzed with a median age of 64 years. Overall average cardiac metric compliance was 91.7%. Utilization of motion management increased from 41.8% in 2016 to 2020 to 46.5% in 2021 to 2022. Similarly, use of prone positioning increased from 12.2% to 22.2% in these periods. On multivariate analysis in the 2016 to 2020 cohort, treatment with motion management (odds ratio [OR], 5.20; 95% CI, 3.59-7.54; P < .0001) or prone positioning (OR, 3.21; 95% CI, 1.85-5.57; P < .0001) was associated with meeting the MHD goal, while receipt of boost (OR, 0.25; 95% CI, 0.17-0.39; P < .0001) and omission of hormone therapy (OR, 0.65; 95% CI, 0.49-0.88; P = .0047) were associated with not meeting the MHD goal. From 2021 to 2022, treatment with motion management (OR, 1.89; 95% CI, 1.12-3.21; P = .018) or prone positioning (OR, 3.71; 95% CI, 1.73-7.95; P = .0008) was associated with meeting the combined MHD/PTV goal, while larger breast volume (≥1440 cc; OR, 0.34; 95% CI, 0.13-0.91; P = .031) was associated with not meeting the combined goal. CONCLUSIONS: In our statewide consortium, high rates of compliance with aggressive targets for limiting cardiac dose were achievable without sacrificing target coverage.
