Abstract Purpose: To determine the dose limiting toxicities (DLT), maximum tolerated dose (MTD), and recommended phase II dose (RP2D) of veliparib in combination with weekly topotecan in patients with solid tumors. Correlative studies were included to assess the impact of topotecan and veliparib on poly(ADP-ribose) levels in peripheral blood mononuclear cells, serum pharmacokinetics of both agents, and potential association of germline repair gene mutations with outcome. Experimental Design: Eligible patients had metastatic nonhematologic malignancies with measurable disease. Using a 3 + 3 design, patients were treated with veliparib orally twice daily on days 1–3, 8–10, and 15–17 and topotecan intravenously on days 2, 9, and 16 every 28 days. Tumor responses were assessed by RECIST. Results: Of 58 patients enrolled, 51 were evaluable for the primary endpoint. The MTD and RP2D was veliparib 300 mg twice daily on days 1–3, 8–10, and 15–17 along with topotecan 3 mg/m2 on days 2, 9, and 16 of a 28-day cycle. DLTs were grade 4 neutropenia lasting >5 days. The median number of cycles was 2 (1–26). The objective response rate was 10%, with 1 complete and 4 partial responses. Twenty-two patients (42%) had stable disease ranging from 4 to 26 cycles. Patients with germline BRCA1, BRCA2, or RAD51D mutations remained on study longer than those without homologous recombination repair (HRR) gene mutations (median 4 vs. 2 cycles). Conclusions: Weekly topotecan in combination with veliparib has a manageable safety profile and appears to warrant further investigation.
Healthy Exercise Habits Are Associated With Lower Risk of Burnout and Higher Quality of Life Among U.S. Medical Students
Purpose Although burnout and low quality of life (QOL) are common among medical students, little remains known about personal fitness habits of medical students that may promote well-being. Method In 2012 the authors conducted a cross-sectional study of U.S. medical students to explore relationships between burnout, QOL, and compliance with Centers for Disease Control and Prevention (CDC) exercise recommendations. Wilcoxon-Mann-Whitney tests, Fisher exact tests, and multivariate logistic regression were performed. Results Among approximately 12,500 medical students invited to participate, 4,402 (35.2%) completed surveys. Most (2,738/4,367; 62.7%) engaged in aerobic exercise in accordance with CDC recommendations, while fewer (1,685/4,376; 38.5%) adhered to muscle strengthening recommendations. Burnout prevalence was lower among students who exercised aerobically consistent with CDC recommendations compared with those who exercised less (53.1% vs. 60.8%, P < .0001). Similarly, rates of burnout were also lower among students who strength trained consistent with CDC recommendations (51.8% vs. 58.6%, P < .0001). Overall QOL scores were higher for medical students adhering to CDC recommendations for aerobic exercise (7.2 vs. 6.6, P < .0001), strength training (7.2 vs. 6.8, P < .0001), or both aerobic and strength training (8.0 vs. 7.0, P < .0001). Compliance with CDC exercise guidelines remained independently associated with lower risk of burnout and higher QOL on multivariate analysis controlling for age, sex, relationship status, children, and year in school. Conclusions Students whose aerobic exercise and/or strength training habits are consistent with CDC guidelines appear less likely to experience burnout and to have higher QOL.
Purpose To explore the relationship between alcohol abuse/dependence with burnout and other forms of distress among a national cohort of medical students. Method In 2012, the authors completed a national survey of medical students from the American Medical Association’s Physician Masterfile containing validated items assessing alcohol abuse/dependence, burnout, depression, suicidality, quality of life (QOL), and fatigue. Descriptive and comparative statistical analyses were computed, including chi-square and multivariate logistic regression, to determine relationships between variables. Results Of the 12,500 students, 4,402 (35.2%) responded. Of these, 1,411 (32.4%) met diagnostic criteria for alcohol abuse/dependence. Students who were burned out ( P = .01), depressed ( P = .01), or reported low mental ( P =.03) or emotional ( P = .016) QOL were more likely to have alcohol abuse/dependence. Emotional exhaustion and depersonalization domains of burnout were strongly associated with alcohol abuse/dependence. On multivariate analysis, burnout (OR 1.20; 95% CI 1.05–1.37; P < .01), having $50,000 to $100,000 (OR 1.21 versus < $50,000; CI 1.02–1.44; P < .05) or > $100,000 (OR 1.27 versus < $50,000; CI 1.08–1.48; P < .01) of educational debt, being unmarried (OR 1.89; CI 1.57–2.27; P < .001), and being younger (for every five years, OR 1.15; CI 1.02–1.28; P = .01) were independently associated with increased risk for alcohol abuse/dependence. Conclusions Burnout was strongly related to alcohol abuse/dependence among sampled medical students and increased educational debt predicted a higher risk. A multifaceted approach addressing burnout, medical education costs, and alcohol use is needed.
The prevalence of substance use disorders in American physicians
Purpose To evaluate the career plans, professional expectations, and well-being of oncology fellows compared with actual experiences of practicing oncologists. Methods US oncology fellows taking the 2013 Medical Oncology In-Training Examination (MedOnc ITE) were invited to participate in an optional postexamination survey. The survey evaluated fellows' career plans and professional expectations and measured burnout, quality of life (QOL), fatigue, and satisfaction with work-life balance (WLB) using standardized instruments. Fellows' professional expectations and well-being were compared with actual experiences of US oncologists assessed simultaneously. Results Of the 1,637 oncology fellows in the United States, 1,373 (83.9%) took the 2013 MedOnc ITE. Among these, 1,345 (97.9%) completed the postexamination survey. The frequency of burnout among fellows decreased from 43.3% in year 1 to 31.7% in year 2 and 28.1% in year 3 (P < .001). Overall, the rate of burnout among fellows and practicing oncologists was similar (34.1% v 33.7%; P = .86). With respect to other dimensions of well-being, practicing oncologists had lower fatigue (P < .001) and better overall QOL scores (P < .001) than fellows but were less satisfied with WLB (P = .0031) and specialty choice (P < .001). Fellows' expectations regarding future work hours were 5 to 6 hours per week fewer than oncologists' actual reported work hours. Levels of burnout (P = .02) and educational debt (P ≤ .004) were inversely associated with ITE scores. Fellows with greater educational debt were more likely to pursue private practice and less likely to plan an academic career. Conclusion Oncology fellows entering practice trade one set of challenges for another. Unrealized expectations regarding work hours may contribute to future professional dissatisfaction, burnout, and challenges with WLB.
Satisfaction With Work-Life Balance and the Career and Retirement Plans of US Oncologists
Purpose To evaluate satisfaction with work-life balance (WLB) and career plans of US oncologists. Methods The American Society of Clinical Oncology conducted a survey of US oncologists evaluating satisfaction with WLB and career plans between October 2012 and March 2013. The sample included equal numbers of men and women from all career stages. Results Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys. From 1,117 oncologists (37.3% of overall sample) completing full-length surveys, we evaluated satisfaction with WLB and career plans among the 1,058 who were not yet retired. The proportion of oncologists satisfied with WLB (n = 345; 33.4%) ranked lower than that reported for all other medical specialties in a recent national study. Regarding career plans, 270 oncologists (26.5%) reported a moderate or higher likelihood of reducing their clinical work hours in the next 12 months, 351 (34.3%) indicated a moderate or higher likelihood of leaving their current position within 24 months, and 273 (28.5%) planned to retire before 65 years of age. Multivariable analyses found women oncologists (odds ratio [OR], 0.458; P < .001) and those who devoted greater time to patient care (OR for each additional hour, 0.977; P < .001) were less likely to be satisfied with WLB. Satisfaction with WLB and burnout were the strongest predictors of intent to reduce clinical work hours and leave current position on multivariable analysis. Conclusion Satisfaction with WLB among US oncologists seems lower than for other medical specialties. Dissatisfaction with WLB shows a strong relationship with plans to reduce hours and leave current practice. Given the pending US oncologist shortage, additional studies exploring interactions among WLB, burnout, and career satisfaction and their impact on career and retirement plans are warranted.
Burnout and Career Satisfaction Among US Oncologists
Purpose To evaluate the personal and professional characteristics associated with career satisfaction and burnout among US oncologists. Methods Between October 2012 and March 2013, the American Society of Clinical Oncology conducted a survey of US oncologists evaluating burnout and career satisfaction. The survey sample included equal numbers of men and women and represented all career stages. Results Of 2,998 oncologists contacted, 1,490 (49.7%) returned surveys (median age of respondents, 52 years; 49.6% women). Among the 1,117 oncologists (37.3% of overall sample) who completed full-length surveys, 377 (33.8%) were in academic practice (AP) and 482 (43.2%) in private practice (PP), with the remainder in other settings. Oncologists worked an average of 57.6 hours per week (AP, 58.6 hours per week; PP, 62.9 hours per week) and saw a mean of 52 outpatients per week. Overall, 484 oncologists (44.7%) were burned out on the emotional exhaustion and/or depersonalization domain of Maslach Burnout Inventory (AP, 45.9%; PP, 50.5%; P = .18). Hours per week devoted to direct patient care was the dominant professional predictor of burnout for both PP and AP oncologists on univariable and multivariable analyses. Although a majority of oncologists were satisfied with their career (82.5%) and specialty (80.4%) choices, both measures of career satisfaction were lower for those in PP relative to AP (all P < .006). Conclusion Overall career satisfaction is high among US oncologists, albeit lower for those in PP relative to AP. Burnout rates among oncologists seem similar to those described in recent studies of US physicians in general. Those oncologists who devote the greatest amount of their professional time to patient care seem to be at greatest risk for burnout.
