ABSTRACT Background ASP‐1929 photoimmunotherapy—cetuximab conjugated to IRDye 700DX and red light (690 nm) for localized drug activation—results in rapid, selective cell killing. Methods This phase Ib/II open‐label study evaluated ASP‐1929 photoimmunotherapy plus pembrolizumab in patients with recurrent/metastatic HNSCC (≥ 1 accessible lesion, PD‐L1 combined positive score ≥ 1, ineligible for standard locoregional therapy). Primary objectives were safety/tolerability and objective response rate (ORR). Secondary objectives included overall survival (OS) and progression‐free survival (PFS). Results Eighteen patients (median age 63 years, 74% male) comprised the photoimmunotherapy‐evaluable population. The confirmed ORR was 27.8% (95% CI 9.7–53.5); four of five responders had complete responses (95% CI, 6.4–47.6). Median OS was 25.6 months (95% CI, 14.6–not evaluable); median PFS was 2.9 months (95% CI, 1.4–14.6). The most common serious adverse reactions were dysphagia and tongue edema (each n = 2; 10.5%). Conclusions ASP‐1929 photoimmunotherapy plus pembrolizumab was generally tolerable, with promising efficacy in patients with recurrent/metastatic HNSCC.

PURPOSE Although international medical graduates (IMGs) and Puerto Rican Medical Graduates (PRMGs) comprise an integral part of the health care workforce, these individuals, particularly women, frequently face numerous types of discrimination throughout medical training and independent practice. To our knowledge, we conducted the first cross-sectional study to understand the journeys and consequences of migration faced by IMGs and PRMGs in the US oncology workforce. METHODS We developed a cross-sectional, online survey consisting of 51 multiple choice and open-ended questions that captured demographic information, professional status, period of migration to the United States, location within the United States that participants migrated to, reasons for migration, cultural adaptation, experiences of discrimination during training, and overall professional experiences in the United States. RESULTS The majority of participants cited better education, professional gains, and a lack of opportunities in participants' home country as primary reasons for migration to the United States. However, most participants, particularly women, experienced staunch assimilation to fit the mold of professional American standards; women were also particularly likely to report experiences of racial/ethnic, language, and gender discrimination during oncology training in the United States, which only marginally improved during independent practice. Despite such discrimination, most participants reported excellent professional satisfaction during training and independent practice, although only moderate personal satisfaction. Most participants decided to stay in the United States, citing reasons pertaining to enhanced professional opportunities, whereas those that returned home valued reasons relating to family and quality of life. CONCLUSION Our sobering findings underscore the need for institutional enforcement of an inclusive environment encompassing cultural humility, enactment of programs addressing barriers to socialization, immigration laws, and financial support, creation of IMG-specific support networks, and the sponsorship and promoting of minority women physicians.

9011 Background: 'Gender disparities' is a familiar term in medicine. Only 35.2% of oncologists in the U.S. self-identified as women in 2021. Women in medicine are undercompensated and underpromoted. Little is known of the experiences of non-U.S. female physicians in the U.S. We created the first cross-sectional study to assess gender disparities in IMGs and Puerto Rican medical graduates (PRMGs) in oncology in the U.S. Methods: An anonymous online survey was created and distributed via Survey Monkey. Eligible participants were non-U.S. IMGs and PRMGs who trained and/or practiced independently in the U.S. Participants were recruited through email and social media from Sept-Dec 2023. Bivariate association analyses were performed using the two-sample Wilcoxon test for ordered categorical variables and Fisher’s exact test for nominal categorical variables. Results: 97 IMGs and PRMGs in oncology completed the survey. As shown in the table, women were more likely to move to the U.S. for family (22.4% vs 6.2%, p=0.040), whereas men did more for financial gains (20.8% vs 6.1%, p=0.040). culture, particularly to the traditions (65.3% vs 43.8%;p=0.042) and dress code (44.9% vs 20.8%, p=0.017). Women experienced higher rates of gender discrimination during training (53.2% vs 4.5%, p <0.001) and independent practice (57.6% vs 3.6%, p<0.001) than men. Women were also more likely than men to face ethnic/racial discrimination during training (69.6% vs 38.1%; p=0.005). Despite lack of statistical significance, higher trends of ethnic/racial discrimination during independent practice were reported by women (table). More women reported no plans on returning home (68.8% vs 38.3%), whereas more men planned to return home at some point (38.3% vs 16.7%). 18.8% of men vs 0% of women elected leadership opportunities as the reason for returning to their home country (p=0.001). Conclusions: Our study reveals the unfortunate reality that many IMG and PRMG women face in oncology in the U.S. Despite national efforts to reduce the gap in gender disparities, minority women continue to experience racial/ethnic and gender discrimination at higher rates than men. To overcome inequities and achieve gender equity pay transparency, diversity in selection committees is necessary. Further, efforts should be across all settings, academia, private practice, and industry. The time for gender equity in oncology is now. [Table: see text]

9001 Background: With an increasingly diverse patient population in the U.S., the need for a diverse clinician workforce has been exemplified. In 2021, 28% of the practicing physicians in the U.S. were born/trained outside of the continental U.S. Though strides in promoting diversity among oncologists have been made, continuous longitudinal assessments and improvements are important to ensure goals are met. We conducted the first cross-sectional study to understand the challenges and experiences of IMGs and Puerto Rican (PR) medical graduates in oncology in the U.S. Methods: An anonymous online questionnaire via Survey Monkey was developed. Non-U.S. IMGs and PRMGs who trained and/or practicing independently in the U.S. were eligible to participate. The study launched on Twitter with promotional materials, inviting participants to complete the survey. A list of IMGs and PR medical graduates was also compiled and an email invitation with the survey link was sent to. The enrollment period was from Sept-Dec 2023. Data was analyzed using descriptive statistics. Results: 97 participants from oncology-related fields completed the survey. Most were attendings (62.9%), and women (50.5%). 95.9% were IMGs and 5.2% PRMGs. 79.4% participants migrated after medical school and 90.7% were still living In the U.S. The main reasons for migrating were looking for better training (63.9%), seeking professional gains (57.7%), and lack of opportunities in their home country (49.5%). Most had to adapt to new cuisine (51.5%), community (53.6%), traditions (54.6%), and celebrations (58.8%). Participants expressed the need to change their dress code (33%), tone of voice (39.2%), the way they spoke (51.5%), and conducted themselves (49.5%). Participants faced racial/ethnic (54.5%), gender (29.7%), and language (41.9%) discrimination during training in the U.S. Similarly, they experienced racial/ethnic (46.8%), gender (32.8%), and language (24.6%) discrimination during independent practice in U.S. Most participants reported moderate personal (57%), yet extreme professional (57.4%) satisfaction in the U.S. 10.5% of participants had returned to their home country, 27.4% planned to, and 53.7% did not plan to return. The main reasons for going back home were family (67%), quality of life (28.9%), and feelings of isolation/lack of community (22.7%). Conclusions: Our study reveals that the main reasons physicians migrate to the U.S. is for education and professional opportunities. Yet these could come at a high cost, leading foreign-born physicians to compromise their true identities. Despite increasing representation of IMGs and PRMGs in the medical field in the U.S., they remain victims of discrimination at frequent rates. It is imperative to implement changes beyond diversifying the work field and strive for equity to create a more conducive environment for minority physicians.

11014 Background: The well-being of oncology providers (OP) is in jeopardy with increasing workload, limited resources, and personal challenges that result from the COVID-19 pandemic. We aim to evaluate the impact of COVID-19 on work-related (WR) satisfaction and fatigue among OP in Latin America. Methods: We conducted an international cross-sectional online survey of OP practicing in Latin America. The survey was administered in English, Spanish, and Portuguese. Data was analyzed using descriptive statistics and Chi-square tests. Results: In August 2020, 704 OP from 20 Latin American countries completed the survey (77% of 913 who started the survey). Table outlines baseline characteristics. Higher frequency of WR fatigue (67% vs. 58%, p=0.010) and exhaustion (81% vs. 70%, p=0.001) were reported by OP who cared for patients with COVID-19, compared to OP who cared for patients without COVID-19. Providers that observed delays in referrals to radiation (p=0.002) and surgery (p=0.04) reported WR fatigue at higher rates than their counterparts. Higher exhaustion (p=0.016) and dissatisfaction (p=0.046) were reported by OP who lacked access to supportive services, as social work. A significantly higher proportion of women reported WR fatigue (72% vs. 56%, p=0.003) and exhaustion (86% vs. 68%, p=0.001), when compared to men. Women were more likely than men to endorse higher current levels of fatigue when compared to pre-COVID-19 (61% vs. 46%, p=0.0001). To reduce stress, women were more likely than men to cut the time spent watching the news (p=0.002). Both genders declined research collaborations and speaking opportunities. Conclusions: Fatigue and dissatisfaction with work-life were prevalent among OP in Latin America. Higher rates of WR fatigue were seen in women, OP caring for patients with COVID-19, and OP with patients who experienced cancer care delays. Our data imply that OP may be a prime target for psychosocial support, particularly as current challenges will continue for the foreseen future. Baseline characteristics (N=704).[Table: see text]

1537 Background: The severe acute respiratory syndrome 2 (SARS-cov-2) virus causing COVID-19 has brought great challenges to global health services affecting cancer care delivery, outcomes, and increasing the burden in oncology providers (OP). Our study aimed to describe the challenges that OP faced while delivering cancer care in Latin America. Methods: We conducted an international cross-sectional study using an anonymous online survey in Spanish, Portuguese, and English. The questionnaire included 43 multiple choice questions. The sample was stratified by OP who have treated patients with COVID-19 versus those who have not treated patients with COVID-19. Data was analyzed with descriptive statistics and Chi-square tests. Results: A total of 704 OP from 20 Latin American countries completed the survey (77% of 913 who started the survey). Oncologists represented 46% of respondents, followed by 25% surgical-oncologists. Of the respondents, 56% treated patients with COVID-19. A significant proportion of OP reported newly adopting telemedicine during COVID-19 (14% vs 72%, p=0.001). More than half (58%) of OP reported making changes to the treatments they offered to patients with cancer. As shown in the table, caring for patients with COVID-19 significantly influenced practice patterns of OP. Access to specialty services and procedures was significantly reduced: 40% noted significantly decreased or no access to imaging, 20% significantly decreased or no access to biopsies, 65% reported delays in surgical oncology referrals, and 49% in radiation oncology referrals. A vast majority (82%) reported oncologic surgeries were delayed or cancelled, which was heightened among those treating patients with COVID-19 (87% vs 77%, p=0.001). Conclusions: The COVID-19 pandemic has significantly affected the way cancer care is delivered in globally. Although changes to healthcare delivery are necessary as a response to this global crisis, our study highlights the significant disruption and possible undertreatment of patients with cancer in Latin America that results from COVID-19.[Table: see text]
