The Radiation Oncology Mentorship Initiative: Analysis of a Formal Mentoring Initiative for Medical Students Interested in Radiation Oncology.

The importance of mentorship in medicine and its impact on academic and professional development has been widely studied. However, mentorship for medical students in the field of radiation oncology is limited. Our radiation oncology department developed a formal medical student mentorship program in 2004. This program included both clinical and research mentoring pathways. Our study aims to gain feedback and perspective from former medical student participants who subsequently entered into a radiation oncology residency program. An anonymous survey was sent to 22 former students in the mentorship program from 2005 to 2016 who entered a radiation oncology residency program. The survey included Likert scales (1-5), multiple choice, strength category rankings, and free responses. Data was compiled and analyzed with Qualtrics data software. The survey response rate was 100%. Seventeen (77.3%) participants reported that the mentorship program strongly affected their career choice and a majority reported that their research experience strongly (45.5%) or moderately affected (31.8%) their career choice. Fourteen (63.6%) respondents reported that the mentorship program was very effective and 8 (36.4%) reported it as being effective. Eighteen (81.8%) respondents reported that mentorship was extremely important to their career. Students participating in the research pathway also reported improvement in valuable skills such as presentations, abstract writing, manuscript writing, statistical analysis, and coordination with colleagues. A total of 66.7% of attending radiation oncologists who previously participated in this program now practice in an academic setting. Our institution successfully developed a formalized mentorship program for medical students interested in radiation oncology. Participants in this program reported high levels of satisfaction and emphasized the importance of mentorship in the development of valuable research competencies and on their overall career path. This program can serve as a model for future mentorship initiative in medical school.

Impact of patient demographics, tumor characteristics, and treatment type on treatment delay throughout breast cancer care at a diverse academic medical center.

PURPOSE AND OBJECTIVE: The aim of this study was to examine the impact of patient demographics, tumor characteristics, and treatment type on time to treatment (TTT) in patients with breast cancer treated at a safety net medical center with a diverse patient population. PATIENTS AND METHODS: A total of 1,130 patients were diagnosed and treated for breast cancer between 2004 and 2014 at our institution. We retrospectively collected data on patient age at diagnosis, race/ethnicity, primary language spoken, marital status, insurance coverage, American Joint Committee on Cancer (AJCC) stage, hormone receptor status, and treatment dates. TTT was determined from the date of breast cancer biopsy to treatment start date. Nonparametric Mann-Whitney U-test (or Kruskal-Wallis test when appropriate) and multivariable quantile regression models were employed to assess for significant differences in TTT associated with each factor. RESULTS: Longer median TTT was noted for Black (P=0.002) and single (P=0.002) patients. AJCC stage IV patients had shorter TTT (27.5 days) compared to earlier AJCC patients (36, 35, 37, 37 days for stage 0, I, II, III, respectively), P=0.028. Age, primary language spoken, insurance coverage, and hormone receptor status had no significant impact on TTT. On multivariate analysis, race/ethnicity remained the only significant factor with Black reporting longer TTT, P=0.025. However, race was not a significant factor for time from first to second treatment. More Black patients were noted to be single (P<0.0001) and received chemotherapy as first treatment (P=0.008) compared to White, Hispanic, or other race/ethnicity patients. CONCLUSION: In this retrospective analysis, Black patients had longer TTT, were more likely to receive chemotherapy as first treatment, and have a single marital status. These patient factors will help identify vulnerable patients and guide further research to understand the barriers to care and the impact of treatment delays on outcomes.

Effect of Patient Demographic Characteristics and Radiation Timing on PSA Reduction in Patients Treated With Definitive Radiation Therapy for Prostate Cancer.

INTRODUCTION: The purpose of this study was to assess how demographic characteristics and temporal factors including time to treatment (TTT) and elapsed time of treatment (ETT) affect prostate-specific antigen (PSA) levels during and after radiation treatment for low- and intermediate-risk prostate cancer. PATIENTS AND METHODS: A retrospective review of 1584 patients was conducted on patients diagnosed with prostate cancer between 2005 and 2013, from which 147 patients were found to have completed definitive external beam radiation therapy (EBRT) monotherapy. Demographic data, TTT (days between diagnosis and EBRT start date), ETT (days between EBRT start and stop date), and Gleason score were collected on these patients and analysis of variance was performed to analyze the relationship of these factors with PSA changes. PSA changes were calculated during treatment as the difference between pre- and posttreatment PSA levels and after treatment as 3-year and overall PSA velocities. RESULTS: Patients who spoke Haitian Creole (P = .039) and those with a longer ETT (P = .029) had significantly greater PSA decline during treatment, primarily as a result of higher pretreatment PSA levels. Patients with Gleason score 4+3 disease had significantly greater 3-year (P = .033) and overall (P = .019) PSA velocities. Race and/or ethnicity, insurance type, marital status, and age were not associated with any PSA variable. CONCLUSION: Disparities in prostate cancer are not reflected in PSA dynamics during or after radiation treatment, but are evident in PSA level at presentation. Timeliness of treatment was not found to affect true PSA change due to EBRT in low- and intermediate-risk prostate cancer patients.

Medical student mentorship in radiation oncology at a single academic institution: A 10-year analysis.

PURPOSE: Mentorship has been identified by medical students, residents, and faculty as an important component of specialty selection and research productivity in radiation oncology. This study quantitatively analyzes the impact of a mentorship program in radiation oncology targeted to medical students at our institution. METHODS AND MATERIALS: We performed a retrospective review of 76 current or former medical students who were mentored by faculty radiation oncologists at our institution between 2004 and 2013. Data were collected from the medical school's Office of Student Affairs and from internal departmental records. Mentees were organized by mentorship tracks, which included a clinical track and a research track. For each track, data were compiled and analyzed for student specialty selection, and Fisher exact tests were used to determine the relative significance of exposure to clinical, research, or both tracks on student likelihood of pursuing residency in radiation oncology relative to other specialties. We further tracked the research productivity of mentees in the program, as determined by the number publications that were coauthored by mentees and mentors each year. RESULTS: The absolute number of mentees has grown each year, with a total of 76 mentees, including 58 alumni, at the end of 2013. Mentees in the program have produced a total of 53 manuscripts, given 75 presentations at national conferences, and received numerous national and internal medical school research awards. Of the 58 alumni, 17 (29.3%) applied to and matched into radiation oncology residencies. Alumni of both the research and the clinical track were 5.76 (P < .01) times more likely to enter a radiation oncology residency program than the average single-track alumnus. CONCLUSIONS: Mentorship in medical school is an important factor in the development of future radiation oncologists. These results demonstrate the positive impact mentorship has on specialty selection and research productivity.

Patient demographic characteristics and disease stage as drivers of disparities in mortality in prostate cancer patients who receive care at a safety net academic medical center.

INTRODUCTION: The purpose of this study was to examine the effect of patient demographic characteristics and tumor stage at diagnosis on mortality in prostate cancer patients who receive care at a safety net, academic medical center with a diverse patient population. PATIENTS AND METHODS: Eight hundred sixty-nine patients were diagnosed with prostate cancer at our institution between August 2004 and October 2011. Patient demographic characteristics were determined as follows: race and/or ethnicity, primary language, insurance type, age at diagnosis, marital status, income (determined by zip code), and American Joint Committee on Cancer (AJCC) tumor stage. Fisher exact or Pearson χ(2) test was used to test for differences in categorical variables. Multivariate logistic regression analysis was performed to identify factors related to mortality recorded at the end of follow-up in March of 2012. RESULTS: Mortality was significantly decreased in patients who spoke Haitian Creole (odds ratio [OR], 0.18; 95% confidence interval [CI], 0.04-0.74; P = .017). Distribution of insurance type, age, income, and prostate-specific antigen level differed between English and Haitian Creole speakers. Increased mortality was observed in patients who were single (OR, 1.99; 95% CI, 1.06-3.73; P = .032), older than 70 (OR, 15.5; 95% CI, 3.03-79.45; P = .001), had Medicaid and/or free care (OR, 4.98; 95% CI, 1.72-14.4; P = .003), or had AJCC stage IV cancer (OR, 9.56; 95% CI, 4.89-18.69; P < .001). There was no significant difference in mortality according to race and/or ethnicity or income in the multivariate-adjusted model. CONCLUSION: In this retrospective study, prostate cancer patients who spoke Haitian Creole had a lower incidence of mortality compared with English speakers. Consistent with similar large-scale studies, being single or having Medicaid and/or free care insurance predicted worse outcomes, reinforcing their roles as drivers of disparities.
