RESUMO
Black women experience disproportionate rates of advanced breast cancer diagnoses and mortality. Mammography is a proven and effective tool in early breast cancer detection and impacts patient outcomes. We interviewed Black women with a personal or family history of breast and/or ovarian cancer to understand their screening experiences and views. N = 61 individuals completed an interview. Interview transcripts were qualitatively analyzed for themes regarding clinical experiences, guideline adherence, and family sharing specific to Black women and their families. Most participants were college educated with active health insurance. Women in this cohort were knowledgeable about the benefits of mammography and described few barriers to adhering to annual mammogram guidelines. Some with first-degree family history were frustrated at insurance barriers to mammography before the age of 40. Participants were generally comfortable encouraging family and friends to receive mammograms and expressed a desire for a similar screening tool for ovarian cancer. However, they expressed concern that factors such as screening awareness and education, lack of insurance coverage, and other systematic barriers might prevent other Black women from receiving regular screening. Black women in this cohort reported high adherence to mammography guidelines, but expressed concern about cultural and financial barriers that may impact cancer screening access in the population more generally and contribute to disparities. Participants noted the importance of frank and open discussions of breast cancer screening in their families and community as a means of improving awareness.

Study conducted to determine frequency and timing of unplanned breast implant removal after mastectomy, reconstruction, and postmastectomy radiation (PMRT). From 2010-2017, 52 patients underwent mastectomy, reconstruction, and PMRT. With median follow-up of 3.1 years, 23 patients (44%) experienced implant removal. Implant removal occurred in 9 (17%) patients before starting PMRT and 14 (27%) patients after starting PMRT. Implant removal rates were similar for hypofractionated PMRT compared with standard fractionation and for proton compared with photon PMRT. Implant removal is common for women undergoing mastectomy and reconstruction followed by PMRT. The risk is clinically significant even before starting radiation.

BACKGROUND: The goal of this study was to assess the impact of trastuzumab on locoregional failure. METHODS: The analysis included 2763 patients with HER2-positive (HER2+) breast cancer who were randomly assigned to adjuvant doxorubicin (A), cyclophosphamide (C), paclitaxel (T) and trastuzumab (H) (arm A, ACâT [n = 922]; arm B, ACâTâH [n = 988]; arm C, ACâT+HâH [n = 853]). Radiotherapy was given after ACâT concurrently with H. Radiotherapy was given after lumpectomy (L) or after mastectomy (M) with ≥4 positive lymph nodes but was optional for 1 to 3 positive lymph nodes. Locoregional failures at 10 years (LFR10) as first events were compared using competing risk analysis. RESULTS: The median follow-up was 13.0 years. The first site of failure was local-only in 96 cases, locoregional in 16 cases, regional in 32 cases, and not specified in 2 cases; LFR10 was 4.8% (95% CI 4.1%-5.7%). LFR10 was 5.5% (95% CI 4.3%-7.2%), 4.9% (95% CI 3.7%-6.4%), and 2.8% (95% CI 1.9%-4.1%) in arms A, B, and C (B vs A: hazard ratio [HR] 0.91, P = .62; C vs A: HR 0.72, P = .12). For estrogen receptor-positive patients, LFR10 was 3.7% (95% CI 2.8%-4.8%) and for estrogen receptor-negative patients, it was 6.1% (95% CI 5.0%-7.4%; HR 0.61, P = .004). Local treatment included L+RT (n = 1044 [38%]), M+RT (n = 1025 [37%]), and M (n = 694 [25%]). LFR10 was 6.% (95% CI 5.0%-7.8%), 3.0% (95% CI 2.1%-4.3%), and 5.5% (95% CI 4.0%-7.4%) for L+RT, M+RT, and M, respectively (M+RT vs L+RT: HR 0.43, P < .001; M vs L+RT: HR 0.88, P = .57). For 1 to 3 positive lymph nodes, LFR10 was 6.5% (95% CI 4.8%-8.9%), 4.1% (95% CI 2.4%-7.0%), and 4.3% (95% CI 2.9%-6.5%) in L+RT, M+RT, and M, respectively (M vs L+RT: HR 0.68, P = .14; M vs M+RT: HR 1.2, P = .6). CONCLUSION: Low 10-year LFRs were seen regardless of trastuzumab use. Differences in local therapy in patients with 1 to 3 positive lymph nodes did not appear to improve local control. Local therapy studies for HER2+ and other tumor characteristics are important as the role of local therapies continues to evolve.

PURPOSE: To characterize quality of life (QOL) using real-time, electronic patient-reported outcomes (ePROs) and to evaluate adverse events (AEs) and supportive care during head-and-neck radiotherapy (RT) and concurrent chemoradiotherapy (CCRT). METHODS: Sixty-five patients undergoing head-and-neck RT completed electronic, real-time, 12-item linear analog self-assessments (LASA) at baseline, before biweekly appointments, and at the last week of RT. Changes in QOL domains between time points were calculated. Clinical data were collected from the institutional medical record. AEs were recorded at the same time points as the LASA and graded. RESULTS: During head-and-neck RT, most patients had clinically meaningful decreases in all QOL domains except level of support, financial concerns, and legal concerns. QOL domains with the most prevalent, clinically meaningful decreases were fatigue (75.4% of patients; 95% CI, 62.9-84.9%), social activity (70.8%; 95% CI, 58.0-81.1%), and overall QOL (70.8%; 95% CI, 58.0-81.1%). All patients had grade 2 AEs; 35.4% had grade 3 (50.0%, CCRT; 12.0%, RT; P = .002). Weight loss averaged 5.5 kg (6.9 kg, CCRT; 2.8 kg, RT; P < .001). Intravenous hydration was needed in 52.3% (77.5%, CCRT; 12.0%, RT; P < .001); feeding tube placement 40.0% (57.5%, CCRT; 12.0%, RT; P = .001); emergency department visits without hospitalization, 10.8%; and emergent hospitalization, 27.7% (37.5%, CCRT; 12.0%, RT; P = .04). CONCLUSIONS: Head-and-neck RT, particularly CCRT, negatively impacts patients' overall QOL, social activity, and fatigue, with frequent grade 3 AEs, weight loss, intravenous hydration, feeding tube placement, ED visits, and hospitalization. Real-time ePROs allow providers to monitor QOL at multiple time points during RT, potentially allowing early intervention to improve QOL and mitigate AEs.

This work is to show which is more relevant to cause local failures (LFs) due to patient setup uncertainty between the planning target volume (PTV) underdosage and the potential target underdosage subject to patient setup uncertainties in head and neck (H&N) cancer treated with volumetric-modulated arc therapy (VMAT). Thirteen LFs in 10 H&N patients treated by VMAT were analyzed. Measures have been taken to minimize the chances of insufficient target delineation for these patients and the patients were clinically determined to have LF based on the PET/CT scan results by an experienced radiologist and then reviewed by a second experienced radiation oncologist. Two methods were used to identify the possible locations of LF due to underdosage: (a) examining the standard VMAT plan, in which the underdosed volume in the nominal dose distribution (UVN) was generated by subtracting the volumes receiving the prescription doses from PTVs, and (b) plan robustness analysis, in which in addition to the nominal dose distribution, six perturbed dose distributions were created by translating the CT iso-center in three cardinal directions by the PTV margin. The coldest dose distribution was represented by the minimum of the seven doses in each voxel. The underdosed volume in the coldest dose distribution (UVC) was generated by subtracting the volumes receiving the prescription doses in the coldest dose distribution from the volumes receiving the prescription doses in the nominal dose distribution. UVN and UVC were subsequently examined for spatial association with the locations of LF. The association was tested using the binominal distribution and the Fisher's exact test of independence. We found that of 13 LFs, 11 were associated with UVCs (P = 0.011), while three were associated with UVNs (P = 0.99). We concluded that the possible target underdosage due to patient setup uncertainties appeared to be a more relevant factor associated with LF in VMAT for H&N cancer than the compromised PTV coverage at least for the patients included in this study.

This study examined the effect of message framing on African American women's intention to participate in health-related research and actual registration in ResearchMatch (RM), a disease-neutral, national volunteer research registry. A community-engaged approach was used involving collaboration between an academic medical center and a volunteer service organization formed by professional women of color. A self-administered survey that contained an embedded message framing manipulation was distributed to more than 2,000 African American women attending the 2012 national assembly of The Links, Incorporated. A total of 391 surveys were completed (381 after exclusion: 187 containing the gain-framed message and 194 containing the loss-framed message). The majority (57%) of women expressed favorable intentions to participate in health-related research, and 21% subsequently enrolled in RM. The effect of message framing on intention was moderated by self-efficacy. There was no effect of message framing on RM registration; however, those with high self-efficacy were more than 2 times as likely as those with low self-efficacy to register as a potential study volunteer in RM (odds ratio = 2.62, 95% confidence interval [1.29, 5.33]). This investigation makes theoretical and practical contributions to the field of health communication and informs future strategies to meaningfully and effectively include women and minorities in health-related research.

BACKGROUND: Controversy continues regarding the use of adjuvant radiation therapy (RT) and hormonal therapy (HT) for patients undergoing breast-conserving therapy (BCT) for ductal carcinoma in situ (DCIS). METHODS: A prospective database was queried to identify women 18 years of age or older treated for DCIS from 2002 to 2013. RESULTS: BCT was completed for 300 patients with a median age of 66 years. The median DCIS size was 0.7 cm (range 0.1-6.0 cm). The DCIS grades were high (44 %), intermediate (37 %), and low (19 %). The closest margin was wider than 3 mm in 80 % and wider than 5 mm in 63 % of the cases. Adjuvant RT was administered to 183 patients (61 %), and the RT status of 9 patients (3 %) was unknown. RT was associated with age, DCIS size, comedo necrosis, grade, and treatment in 2002-2007 versus 2008-2013. Adjuvant HT was administered to 86 estrogen receptor-positive patients (39 %), and the HT status of 4 patients (2 %) was unknown. The median follow-up period was 63 months (range 4-151 months). The 5-year overall local recurrence (LR) rate was 4 % (95 % confidence interval [CI] 2.1-7.4 %). The 5-year LR rate was 3.9 % (95 % CI 1.8-8.6 %) for the RT patients and 4.1 % (95 % CI 1.6-10.7 %) for the patients not receiving RT. Of 13 LRs, 10 (77 %) were DCIS, and 3 (23 %) were invasive including one node-positive recurrence. CONCLUSIONS: Multidisciplinary and joint decision making in the treatment of DCIS results in a substantial and increasing number of patients forgoing adjuvant RT, adjuvant HT, or both. Reasonable 5-year LR rates suggest that such decision making can appropriately allocate patients to adjuvant therapies.

Ductal carcinoma in situ (DCIS) is a breast neoplasm with potential for progression to invasive cancer. Management commonly involves excision, radiotherapy, and hormonal therapy. Surgical assessment of regional lymph nodes is rarely indicated except in cases of microinvasion or mastectomy. Radiotherapy is employed for local control in breast conservation, although it may be omitted for select low-risk situations. Several radiotherapy techniques exist beyond standard whole-breast irradiation (ie, partial-breast irradiation [PBI], hypofractionated whole-breast radiation); evidence for these is evolving. We present an update of the American College of Radiology (ACR) Appropriateness Criteria® for the management of DCIS. The ACR Appropriateness Criteria® are evidence-based guidelines for specific clinical conditions, which are reviewed every 3 years by a multidisciplinary expert panel. The guideline development and review includes an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi technique) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Although both breast-conserving surgery and mastectomy generally provide excellent local-regional control of breast cancer, local-regional recurrence (LRR) does occur. Predictors for LRR include patient, tumor, and treatment-related factors. Salvage after LRR includes coordination of available modalities, including surgery, radiation, chemotherapy, and hormonal therapy, depending on the clinical scenario. Management recommendations for breast cancer LRR, including patient scenarios, are reviewed, and represent evidence-based data and expert opinion of the American College of Radiology Appropriateness Criteria Expert Panel on LRR.The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel.The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel.

A prospective study was performed for patients with early-stage breast cancer in which a single fraction of intraoperative electron irradiation (IOERT) was given to the tumor bed, followed by conventional fractionated whole-breast irradiation (WBRT). Patients with T1/T2N0 breast cancer underwent lumpectomy and sentinel lymph node biopsy. A tumor bed boost of 10 Gy of IOERT using 6-12 MeV electrons was administered by a dedicated mobile linear accelerator in the operating room. After adequate wound healing, 48 Gy WBRT was given to the whole breast in 24 fractions. Fifty-two patients were enrolled between February 2003 and January 2005. At a median follow-up of 79 months, there were two local relapses. The 6-year actuarial overall survival and distant control rates were 89% and 96%, respectively. At last follow-up, cosmesis was graded as excellent or good in 45 (87%), fair in five (10%), and poor in two patients (4%), respectively. Difficulty in wound healing occurred in two patients who had additional surgery later. One patient developed significant fibrosis after aspiration of a symptomatic seroma. The result of this pilot study shows the feasibility of using IOERT as the tumor bed boost in lieu of 6-8 days of standard electron beam treatment with good local control and cosmetic results. However, late surgical intervention of the lumpectomy bed may result in more pronounced tissue fibrosis and wound healing difficulty.

OBJECTIVES: We evaluated relapse patterns after transoral laser microsurgery (TLM) in squamous cell carcinoma (SCC) of the tonsil and tongue base and evaluated the indications for adjuvant irradiation. METHODS: Between December 1, 1996, and December 31, 2005, 79 patients with previously untreated SCC of the tonsil or tongue base underwent TLM with or without neck dissection. Thirty-eight patients (48%) underwent postoperative irradiation (median, 62 Gy) to the primary site and the neck. Analysis of relapse patterns was performed on the basis of adverse risk factors and the presence or absence of adjuvant irradiation. RESULTS: The median follow-up for living patients was 47 months (range, 10 to 107 months), and patients were monitored for at least 2 years or until recurrence or death. Local, regional, and distant treatment failures numbered 4, 6, and 4 for surgery alone (n = 41) and 0, 2, and 6 for adjuvant irradiation (n = 38), respectively. Patients with high-risk features (extracapsular extension or at least 2 adverse factors) had locoregional control rates at 2 or more years of 66% and 94% for TLM alone and TLM plus adjuvant irradiation, respectively. CONCLUSIONS: Adjuvant irradiation after TLM resection of oropharyngeal SCC with intermediate- or high-risk features improves locoregional control compared with TLM alone.

BACKGROUND: The strong Black woman (SBW) stereotype can be seen as a positive view of Black women and even a standard to uphold. SBW internalization is a coping mechanism for dealing with racism and sexism. However, multiple recent studies have indicated that Black women in the modern era experience the paradox of SBW internalization having negative generational health effects. We interviewed Black women with a personal or relation diagnosis of breast or ovarian cancer to understand their views and experiences, including how the perception of the SBW stereotype influenced their care. METHODS: Qualitative semi-structured interviews were conducted via telephone or video conference and transcribed verbatim. Transcripts were qualitatively analyzed for iterative themes related to cancer care and psychosocial support. RESULTS: Sixty-one Black women completed an interview. Responses in multiple transcripts expressed experiences and sentiments consistent with the SBW stereotype, including the importance of maintaining the appearance of strength during their cancer journey. This resulted in some patients declining assistance during their cancer journeys. Participants shared a hope that there would be more willingness to show vulnerability so that future generations of cancer patients receive adequate support. Key aspects of the SBW stereotype were also cited as potential contributors to ongoing racial disparities in breast and ovarian cancer outcomes. CONCLUSION(S): Participants described a paradox of the SBW stereotype that is ultimately detrimental to health and wellbeing. Healthcare professionals and cancer researchers should be aware of this phenomenon to address cancer care more appropriately in Black women.
RESUMO
PURPOSE: Our aim was to report physician- and patient-reported outcomes of patients with localized breast cancer treated with moderate versus ultrahypofractionated whole breast irradiation (WBI) after breast-conserving surgery (BCS). METHODS AND MATERIALS: Between February 2018 and February 2020, patients with localized breast cancer (pT0-3 pN0-1 M0) were offered participation in a phase 3 randomized clinical trial assessing adjuvant moderate hypofractionation (MHF) to 40 Gy in 15 fractions versus ultrahypofractionation (UHF) to 25 Gy in 5 fractions after BCS, with an optional simultaneously integrated boost. Toxicities, cosmesis, and quality of life were assessed at baseline, end of treatment (EOT), and 3 months, 1 year, 2 years, and 3 years from irradiation using validated metric tools. RESULTS: One hundred seven patients were randomized to MHF (n = 54) or UHF (n = 53) adjuvant WBI. The median follow-up was 42.8 months. Grade 2 radiation dermatitis was experienced by 4 patients (7.4%) in the MHF arm and 2 patients (3.7%) in the UHF arm at EOT (P = .726). No grade 3 or higher toxicities were observed. Deterioration of cosmesis by physician assessment was observed in 2 (6.7%) patients treated in the UHF arm and 1 (1.9%) patient treated in the MHF arm at EOT (P = .534), whereas at 3 months, only 1 (1.8%) patient treated in the MHF arm demonstrated deterioration of cosmesis (P = .315). At EOT, 91% and 94% of patients reported excellent/good cosmesis among those treated with MHF and UHF regimens, respectively (P = .550). At 3 months, more patients within the MHF arm reported excellent/good cosmesis compared with those in the UHF arm (100% vs 91%; P = .030). However, the difference in patient-reported cosmesis disappeared at the 1-, 2-, and 3-year time points. CONCLUSIONS: UHF WBI showed similar treatment-related late toxicities and similar provider-scored cosmesis compared with MHF radiation in patients treated adjuvantly after BCS.

PURPOSE: The optimal approach for partial breast irradiation (PBI) is unknown. We investigated a novel de-intensified 3-fraction PBI regimen for photons, protons, and brachytherapy. METHODS AND MATERIALS: A multicenter nonrandomized controlled trial with the primary outcome of adverse cosmesis at 3 years versus before PBI. Eligibility criteria were age ≥50 years treated with breast-conserving surgery for node-negative estrogen receptor-positive (ER+) invasive breast cancer or any ductal carcinoma in situ (DCIS) measuring ≤2.5 cm. Photon and proton PBI were prescribed 21.9 Gy (relative biological effectiveness) and brachytherapy 21 Gy in 3 fractions. Radiation therapy technique and adjuvant endocrine therapy were selected at physician and patient discretion. RESULTS: Between June 17, 2015, and July 13, 2017, 161 eligible patients were treated with photons (56), protons (49), or brachytherapy (56). Median patient age was 66.8 years. One hundred twenty-six (78.3%) had invasive breast cancer (all ER+) and 35 (21.7%) had DCIS (88.6% ER+). Fifty-four percent of patients with invasive breast cancer and 25.8% of patients with ER+ DCIS initiated and adhered to the prescribed endocrine therapy. The proportion of patients with adverse cosmesis (by trained nurse assessment) was 14.5% at baseline and 2.3% at 3 years (difference, -12.2%; 95% CI, -100% to -6.4%). Adverse cosmesis at the last follow-up, with a median follow-up of 5 years, was 5.7% by nurse assessment, 5.6% by panel assessment of digital photographs, and 5.2% by patient self-report. There were no observed clinically meaningful changes in other patient-reported outcomes, and just 2 grade 2 or higher adverse events, both grade 2, in the brachytherapy cohort. Five-year local recurrence-free survival and progression-free survival were 98.0% and 95.5%, respectively. There were no local recurrences among 60 patients with invasive breast cancer and Ki67 ≤13.25%. CONCLUSIONS: Deintensified 3-day PBI provided favorable disease control, tolerability, and cosmetic outcomes, meeting the prespecified criteria for acceptability. This approach is an attractive option for patients with small node-negative ER+ breast cancer and DCIS.
RESUMO
BACKGROUND: Knowledge regarding behavior of and prognostic factors for Merkel cell carcinoma (MCC) is limited. OBJECTIVE: We sought to further understand the characteristics, behavior, prognostic factors, and optimal treatment of MCC. METHODS: A multicenter, retrospective, consecutive study of patients with known primary MCC was completed. Overall survival and survival free of locoregional recurrence were calculated and statistical analysis of characteristics and outcomes was performed. RESULTS: Among the 240 patients, the mean age at diagnosis was 70.1 years, 168 (70.0%) were male, and the majority was Caucasian. The most common location was head and neck (111, 46.3%). Immunosuppressed patients had significantly worse survival, with an overall 3-year survival of 43.4% compared with 68.1% in immunocompetent patients. In our study, patients with stage II disease had improved overall survival versus those with stage I disease, in a statistically significant manner. Patients with stage III disease had significantly worse survival compared with stage I and with stage II. Primary tumor size did not predict nodal involvement. CONCLUSION: The data presented represent one of the largest series of primary MCC in the literature and confirm that MCC of all sizes has metastatic potential, supporting sentinel lymph node biopsy for all primary MCC. Because of the unpredictable natural history of MCC, we recommend individualization of care based on the details of each patient's tumor and clinical presentation.

BACKGROUND: Knowledge is limited regarding unknown primary Merkel cell carcinoma (UPMCC). OBJECTIVE: We sought to document the characteristics and behavior of UPMCC, and determine the most appropriate treatment. METHODS: A multicenter, retrospective, consecutive study reviewing patients given a diagnosis of UPMCC between 1981 and 2008 was completed. In addition, a literature review of cases of UPMCC was performed. RESULTS: In all, 23 patients with UPMCC are described and 34 cases from previous reports are compiled. Among the 23 new cases of UPMCC, the average age at diagnosis was 66.0 years; the majority of patients were male (87%) and Caucasian (100% of those reported). One patient was immunosuppressed, and 39% had a history of other cancer. After the initial biopsy, 16 patients had further evaluation of the involved lymph node basin. Half of these had additional positive nodes (8 of 16). The majority of patients had lymph node basin involvement only (78%), whereas 22% had lymph node basin and distant metastasis. The most common lymph node basin involved was inguinal. The median size of the involved lymph node at diagnosis was 5.0 cm. At 2 years, the overall survival of stage IIIB UPMCC was significantly improved versus stage IIIB known primary Merkel cell carcinoma (MCC): 76.9% to 36.4%. LIMITATIONS: Limited number of cases and retrospective review are limitations. CONCLUSION: Our data demonstrate improved overall survival in patients with stage IIIB UPMCC versus those with stage IIIB known primary MCC. Because of the unpredictable natural history of UPMCC, we recommend individualization of care based on the details of each patient's clinical presentation.

PURPOSE: The Bowel Function Questionnaire (BFQ) has been used in clinical trials to assess symptoms during and after pelvic radiotherapy (RT). This study evaluated the importance of symptoms in the BFQ from a patient perspective. METHODS: Patients reported presence or absence of symptoms and rated importance of symptoms at baseline, 4 weeks after completion of pelvic RT, and 12 and 24 months after RT. The BFQ measured overall quality of life (QOL) and symptoms of nocturnal bowel movements, incontinence, clustering, need for protective clothing, inability to differentiate stool from gas, liquid bowel movements, urgency, cramping, and bleeding. Bowel movement frequency also was recorded. A content validity questionnaire (CVQ) was used to rate symptoms as "not very important," "moderately unimportant," "neutral," "moderately important," or "very important." RESULTS: Most of the 125 participating patients rated all symptoms as moderately or very important. Generally, patients gave similar ratings for symptom importance at all study points, and ratings were independent of whether the patient experienced the symptom. Measures of greatest importance (moderately or very important) at baseline were ability to control bowel movements (94 %), not having to wear protective clothing (90 %), and not having rectal bleeding (94 %). With the exception of need for protective clothing, the presence of a symptom at 4 weeks was associated with significantly worse QOL (P < .01 for all). CONCLUSIONS: The BFQ has excellent content validity. Patients rated most symptoms as moderately or very important, indicating the BFQ is an appropriate tool for symptom assessment during and after pelvic RT.

BACKGROUND: Black breast and ovarian cancer patients are underrepresented in clinical cancer trials disproportionate to the prevalence of these cancers in Black females. Historically, lower enrollment has been attributed to individualized factors, including medical mistrust, but more recently structural factors, including systemic racism, have received additional scrutiny. We interviewed Black women with a personal or family history of breast and ovarian cancer to understand their views and experiences related to research participation. METHODS: Qualitative interviews were conducted via telephone or video conference and transcribed verbatim. Transcripts were qualitatively analyzed for iterative themes related to the offer and participation in cancer clinical trials and research studies, impact on cancer care, and recommendations to increase enrollment of Black patients. RESULTS: Sixty-one Black women completed an interview. Participants expressed that Black women are underrepresented in cancer research, and that this negatively impacted their own care. Many cited past historical abuses, including the Tuskegee syphilis trial, as a potential factor for lower enrollment but suggested that lower enrollment was better understood in the context of the entirety of their healthcare experiences, including present-day examples of patient mistreatment or dismissal. Participants suggested that proactive community engagement, transparency, and increased representation of Black research team members were strategies likely to foster trust and bolster research participation. CONCLUSION(S): Medical mistrust is only a partial factor in the lower participation of Black patients in cancer research. Researchers should implement the strategies identified by our participants to promote diverse enrollment and ensure that Black patients are included in future therapeutic advances.

BACKGROUND: Promotions in academic medicine are frequently based on number of publications and leadership positions held. While prior study has established women publish less than men, many evaluations are limited to individual specialties and do not evaluate involvement with educational activities. OBJECTIVE: To compare gender differences in academic output, intramural leadership positions, and educational leadership positions of academic physicians. METHODS: The curriculum vitae and de-identified demographic data of all permanent physicians employed at a multi-site academic medical center were reviewed from April to May 2020. Multivariable logistic and Poisson regressions evaluated leadership positions and number of publications. RESULTS: Of 3,359 physicians in the demographic database, 32.3% (nâ=â1,087) were women and 72.5% were white (nâ=â2,510). Of the 3,015 physicians in the curriculum vitae database, 32% (nâ=â962) were women. Women were more likely (pâ<â0.001) to be assistant professor (54% vs. 42.7%) and less likely to be associate (18.1% vs. 20.3%) or full professor (14.6% vs. 29.1%). Women assistant professors published 22% fewer articles (ratio estimateâ=â0.78, pâ<â0.001), associate professors 18% less (coefficientâ=â0.82, pâ<â0.001), and full professors 23% less (coefficientâ=â0.77, pâ<â0.001). Fewer women were program directors for residencies (1.6% vs. 2.9%, pâ=â0.02) or fellowships (5.4% vs. 7.4%, pâ=â0.04), and held fewer division or department leadership positions (OR 0.8, 95% CI as [0.6, 1.0], pâ=â0.03). CONCLUSION: Women physicians do not outperform men across any education, leadership, or publication category. A cultural shift is needed to redefine traditional metrics for leadership appointments if academic medicine hopes to achieve equity.

Purpose: Our purpose was to report the results of a phase II trial of patients with breast cancer treated with hypofractionated whole breast radiation therapy (RT) before breast-conserving surgery (BCS). Methods and materials: Between 2019 and 2020, patients with cT0-T2, N0, M0 breast cancer were enrolled. Patients were treated with hypofractionated whole breast RT, 25 Gy in 5 fractions, 4 to 8 weeks before BCS. Pathologic assessment was performed using the residual cancer burden (RCB). Toxicities were assessed according to Common Terminology Criteria for Adverse Events (version 4). Quality of life was assessed with Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events, The Breast Cancer Treatment Outcome Scale, Linear Analogue Self-Assessment, and Patient-Reported Outcomes Measurement Information System. Results: Twenty-two patients were enrolled. Median follow-up was 7.6 months (range, 0.2-16.8). Seven (32%) and 2 (9%) patients experienced grade 2+ or 3 toxicities, respectively. Overall quality of life Linear Analogue Self-Assessment and Patient-Reported Outcomes Measurement Information System did not change significantly from baseline (P = .21 and P = .72, respectively). There was no clinically significant change (≥1 point) in any of The Breast Cancer Treatment Outcome Scale domains. Only 1 (5%) patient experienced a clinical deterioration that corresponded to a "fair" outcome on the Harvard Cosmesis Scale. At pathologic evaluation, 14 (64%) patients had RCB-0 or RCB-I, including 3 (14%) patients with a pathologic complete response (RCB-0). Eight patients (36%) had RCB-II. No local or distant recurrences have been observed. Conclusions: Extremely hypofractionated whole breast RT before BCS is a feasible approach. There were low rates of toxicities and good cosmesis. Further investigation into this approach with RT before BCS is warranted.
