Background: This qualitative study sought to understand factors related to low rates of screening mammography among transgender and gender-diverse (TGD) individuals and how these rates might be improved. Methods: Individuals who self-reported as TGD were recruited from multiple sites and national patient advocates. Consenting participants completed an individual interview using a semistructured guide informed by the Health Belief Model (HBM). Interview data were analyzed using thematic analysis. Results: A total of 44 individuals completed the interview (median age, 44.9 years; range, 19–77 years); 11% were a racial/ethnic minority; and 52%, 20%, and 25%, respectively, self-identified as a transgender woman, transgender man, or nonbinary. Three themes emerged around constructs in the HBM. First, individuals voiced a hope to be treated equally (“I just want to go to work, pay my taxes, love my family, and go along my day and be a good human”) and described how such equitable treatment during screening guarded against gender dysphoria and favored gender affirmation (“it is affirming…being treated as any other woman”). Second, barriers and facilitators related to mammography were identified, including the need to address cost/low cost (“screenings are a luxury”); prior negative/positive experiences (“they would call my name and look at me but dismiss me”); absence/presence of education (“none of the doctors…ever told me what that process looks like”); and perceived low/high cancer risk (“my mom died pretty young from breast cancer”). Finally, practical recommendations were offered, including individual changing/waiting rooms, hiring gender-diverse staff, and engaging clinicians who provide whole-person, trauma-informed care. Conclusions: Mammographic screening among TGD individuals could be improved by proactively creating safe, affirming spaces; working to lower costs; providing educational materials tailored to the TGD community about cancer risk and the practical aspects of screening; and hiring gender-diverse staff. These recommendations from TGD participants merit implementation as well as further study.

The NCCN Guidelines for Survivorship offer guidance for health care providers who care for survivors of adult-onset cancer. These guidelines include screening, evaluation, and treatment recommendations for common physical and psychosocial problems resulting from cancer and its treatment and provide a framework for care coordination. They also present guidance for helping cancer survivors to enhance their wellness and maintain a healthy lifestyle. This article summarizes the panel’s current recommendations and recent updates regarding anxiety, depression, distress, and trauma in cancer survivors.

Background Invasive micropapillary carcinoma (IMPC) of the breast is associated with a high propensity for lymphovascular invasion and lymph node metastasis. However, whether chemotherapy is associated with improved survival outcomes in these patients remains unclear. Methods This retrospective study analyzed IMPC patients from the SEER database (2010–2018) (n=1,150) and an external validation cohort from Nanjing Drum Tower Hospital (n=199). Propensity score matching assessed chemotherapy’s impact on overall survival (OS) and breast cancer-specific survival (BCSS) in the SEER cohort. A risk stratification model was developed and validated using the external cohort. Results In the SEER cohort, chemotherapy was associated with significantly improved OS (HR = 0.517, 95% CI 0.293-0.910, P = 0.020) but not BCSS. A risk model incorporating marital status, tumor size, subtype, and radiotherapy history identified high- and low-risk groups. Chemotherapy was associated with significantly better OS only for high-risk patients (internal training cohort: HR = 0.577, 95% CI 0.349-0.952, P = 0.029; internal validation cohort: HR = 0.213, 95% CI 0.070-0.647, P = 0.003). External validation consistently confirmed poorer prognosis for high-risk patients (HR = 2.969, 95% CI 1.028-8.571, P = 0.035) and verified the model’s ability to identify patients with differential OS associations with chemotherapy: chemotherapy was associated with better OS in high-risk patients (HR = 0.163, 95% CI 0.031-0.868, P = 0.016), but not in low-risk patients (HR = 0.793, 95% CI 0.153-4.103, P = 0.782). Conclusions Chemotherapy was associated with improved prognosis particularly in high-risk patients with IMPC. However, chemotherapy decisions should be made cautiously for low-risk patients, taking into account a comprehensive assessment of clinical and pathological factors.

e12697 Background: Postpartum-associated breast cancer (PABC) has been defined clinically as breast cancer (BC) diagnosed within the first 5 years of the most recent birth. Though generally rare, incidence rates are increasing in conjunction with delayed childbearing and older maternal age at first birth. Currently, there are limited data regarding serial patient-reported outcomes in this patient population compared to non-PABC patients. Methods: Patients with PABC from the Mayo Clinic Breast Disease Registry who completed baseline, 2, and 4-year surveys were matched 1:1 to BC patients whose cancers occurred more than 5 years after their most recent birth (or in the setting of nulliparity) based on age, clinical stage, treatment received, and tumor subtype. Survey results from the Patient Health Questionnaire-2 (PHQ-2), Patient-Reported Outcomes Measurement Information System-10 (PROMIS-10), and Impact of Event Scale-Revised (IES-R) collected at approximately two and four years after diagnosis were compared between PABC and non-PABC patients. Univariable analyses used Wilcoxon rank sum tests, whereas multivariable analyses employed linear regression models adjusting for potential confounding effects. Results: A total of 222 individuals were included (111 with PABC). A higher proportion of individuals in the PABC cohort were married compared to the non-PABC cohort (80% vs. 42%, p < 0.001); otherwise, the groups were well-balanced across multiple categories, including age, gender, race/ethnicity, menopausal status, and germline mutation status. In univariable analyses, the Year 2 composite PHQ-2 score was significantly worse among individuals with non-PABC (p = 0.04), and the non-PABC cohort reported greater difficulty with sleep (p = 0.03) as measured by IES-R at Year 4. Both associations attenuated in a multivariable analysis controlling for marital status. In marital status-adjusted analyses of Year 4 survey results, PABC participants reported greater difficulty in carrying out social activities but were less likely to report emotional distress as evaluated by PROMIS-10 (compared with non-PABC participants). No other variables were significant univariably or multivariably (p > 0.05). Conclusions: In general, quality of life is similar among survivors of PABC compared to those diagnosed with breast cancer outside the postpartum period (or when nulliparous). However, our findings reveal that individuals with PABC are less likely to experience emotional distress 2 and 4 years after the BC diagnosis, which is unexpected, given that postpartum patients typically report higher levels of distress compared to their non-postpartum counterparts. Further investigation into these findings is warranted.

Abstract Background Anxiety is a common symptom experienced by patients with cancer, who are increasingly interested in non-pharmacologic symptom management. Acupressure, a noninvasive intervention thought to impact the neurohormonal axis, has shown promise in reducing anxiety. However, research on acupressure for anxiety in patients with cancer has been limited. Methods Individuals receiving chemotherapy, who reported baseline anxiety, were eligible for this study. Consenting participants received one 15-minute nurse-led acupressure session and completed pre- and post-intervention surveys. The primary endpoint was a change in anxiety. Participants were also asked about symptoms of nausea, pain, well-being, relaxation, worry, and distress. Participants were invited to learn self-acupressure techniques. These participants were asked to complete a final survey 1-week post-intervention. Results Thirty adult patients participated in this study. Mean baseline anxiety was 5 on a 0 to 10 Likert scale. Immediate post-intervention anxiety scores significantly improved for all thirty patients to an average of 2.0 (P &lt; .001). Mean nausea scores improved from 1.5 at baseline to 0 post-intervention (P &lt; .001), and pain scores improved from 2.0 at baseline to 1.0 post-intervention (P = .001). Participants reported significant improvement in sense of wellbeing (P = .0004), distress (P &lt; .001), ability to achieve relaxation (P &lt; .001), and ability to control their worries (P &lt; .001). The improvement in anxiety, well-being, and relaxation was sustained at one week. 100% of participants stated that they would recommend acupressure for symptom management. Conclusion Acupressure is a promising non-pharmacologic intervention for the management of cancer-associated anxiety.

Purpose To assess how comfortable patients with cancer are in responding to intimate questions on sexual orientation and gender identity (SOGI) and to examine whether question sequencing alters patient-reported comfort. Patients and Methods Patients with cancer were asked to respond to one of two surveys that were provided to patients in a randomized manner and that included seven identical SOGI questions but differed in sequence of responses (upfront vs later debated terms, e.g. “genderqueer”). Using a Likert scale (1 = very uncomfortable to 5 = very comfortable), patients rated comfort. The primary endpoint was the percentage of patients comfortable with the question, “Do you consider yourself to be… [12 response options, including genderqueer]”. Secondary endpoints included differences in comfort based on question sequence or demographics. Write-in comments were captured. Results 74% of patients (95% CI: 70%, 78%) were comfortable when reviewing the primary endpoint SOGI question. Similar comfort levels were reported for the other questions. No significant differences in comfort were observed based on question sequence or demographics. Four themes emerged from write in comments 1) emotional reactions to the questions (“uncomfortable because this question is essentially gender binary”) 2) emotional reactions toward SOGI (“bending over backwards to be politically correct”); 3) concern for privacy and relevance to cancer care (“not sure why this information is needed/necessary”); and 4) constructive remarks (“didn’t know what cisgender was - please define”). Conclusions Most patients with cancer are comfortable in answering SOGI questions. However, their comfort might be enhanced with slight question/response modifications.

PURPOSE This national study was undertaken to determine screening mammography rates among transgender and gender diverse (TGD) individuals. METHODS TGD individuals and cisgender women who qualified to receive screening mammography based on American College of Radiology guidelines were identified in the longitudinal OptumLabs Data Warehouse. The primary end point was the percentage of patients who had high rates of screening (>75% recommended screenings). Multivariable analyses were conducted in a matched population of transgender men to cisgender women to identify and adjust for factors associated with high adherence. Individuals were matched at a 1:4 ratio (transgender men: cisgender women) on age, race/ethnicity, year of enrollment in their health care plan, and duration of follow-up. RESULTS This study focused on 10,478 TGD individuals (3,778 transgender men; 1,294 transgender women; 5,406 with gender dysphoria not meeting other TGD criteria, NMOT) and 6,218,369 cisgender women. For transgender men, transgender women, individuals with gender dysphoria NMOT, and cisgender women, high mammography rates were observed in 41.1% (95% CI, 39.5 to 42.6), 7.4% (95% CI, 6.0 to 8.8), 11.9% (95% CI, 11.0 to 12.7), and 38.3% (95% CI, 38.3 to 38.4), respectively ( P < .0001). When transgender men were compared with 15,112 matched cisgender women, an age-based differential association was observed between sex and high mammography rates (interaction P = .0003); compared with cisgender women, transgender men appeared more likely to manifest high rates of screening at age 40-49 years (odds ratios [ORs], 1.38 [95% CI, 1.28 to 1.50]; P < .0001) and 50-59 years (OR, 1.57 [95% CI, 1.35 to 1.81]; P < .0001) but not in the older age groups. CONCLUSION The relatively high rates of screening mammography in cisgender women and transgender men suggest clinicians are offering mammography to individuals who are at average or high breast cancer risk, as compared with cisgender women, and not to transgender women at low risk.

Abstract Introduction: An Our Practice Advisory (OPA), formerly known as Best Practice Advisory (BPA), is an electronic health record (EHR) tool. OPAs identify key parameters to alert providers of potential interventions that could enhance quality of care. Such functionality is increasingly relevant given the rapid pace of new drug approvals. Within the Mayo Clinic system, we previously identified that amongst Mayo Clinic patients (pts) meeting the MonarchE criteria, 28% of pts did not undergo a documented discussion with their provider regarding the role of adjuvant abemaciclib (Premji, SABCS 2024). Further, a Flatiron study identified that only 40% of eligible pts received abemaciclib (Sandoval, Miami Breast 2025). To address this practice gap, in 2024 we began to implement EHR clinical decision support by creating an OPA trigger for pts eligible for an adjuvant CDK 4/6 inhibitor (CDK 4/6i). Here we report on ‘action taken’ versus not for the OPA and the most common reasons for re-prompts. Methods: The Mayo Breast Disease Group designed an OPA including pts who are within 14 months of a clinical or pathologic diagnosis of high-risk early-stage breast cancer. We leveraged structured data captured in the Epic staging forms (Epic Systems) to identify pts with clinical or pathologic T-stage, N-stage, grade, ± Ki-67/ multigene signature to identify ER+/HER2- pts eligible for adjuvant ribociclib or abemaciclib based on FDA approvals. The OPA was triggered by a patient encounter in oncology when endocrine therapy (but not CDK4/6i) was on the active medication list resulting in a hard stop. The OPA gathered limited details about whether adjuvant CDK4/6 inhibitors were discussed and whether the provider followed a link that resulted in prescribing one—considered an indicator of action taken. In this IRB-exempt quality improvement project, we describe the responses captured in the OPA trigger utilizing Epic tools. Results: The OPA went live on 1/10/2025. Over a 5-month period post OPA initiation, we identified 517 OPA alerts among 332 unique pts. Their median age was 62.5 years, and the majority were female (97%). The median time to resolve the OPA was 17.5 seconds (range 2-567 seconds). 12.6% (65/517) of the time there was ‘action taken’ by selecting the hyperlink to potentially start a treatment plan. Providers selected the following OPA pre-set responses: ‘re-prompt in one month’ 248 (48%), ‘patient not a candidate for therapy’ 48 (9%), ‘patient declines’ 69 (13%), ‘outside oncologist will prescribe’ 36 (7%), ‘not discussed’ 44 (9%), and unknown 72 (14%). The most common free text comments among the 517 OPA alerts (summarized) included: ‘revisit in future’ 108 (21%), ‘too early’ 65 (13%), ‘patient declines’ 66 (13%), ‘outside oncologist will start’ 31 (6%), ‘not a candidate’ 26 (5%), and ‘co-morbidities’ 18 (3%). Erroneous OPA prompting occurred in 14 (3%) who previously failed a CDK4/6i due to toxicity and in 18 (3%) for pts currently on a CDK4/6i. 30 (6%) OPA comments noted that they discussed or started therapy that day. Conclusion: The OPA offered clinical decision support and ensured that clinicians considered prescribing CDK 4/6i in all pts identified as eligible, and captured deferrals. Refinements are needed to ensure appropriate timing of OPA and minimize erroneous firing. The OPA remains active and captures the reason for deferral of adjuvant CDK 4/6i prescription. This data pairs real world decision making to better understand clinically meaningful application of improved invasive disease-free survival (iDFS). Citation Format: S. Premji, P. Advani, S.

Objectives On rare occasions, hiccups can cause morbidity, such as sleep deprivation, aspiration and even death. At times, palliative invasive procedures are considered. This study tested the hypothesis that invasive procedures can provide hiccup palliation with an acceptable safety profile. Methods Multi-site electronic medical data were used to assess adult patients who underwent an invasive procedure for hiccups between January 1995 and January 2022. Hiccup palliation was defined as documented improvement in severity or frequency of this sign/symptom after the procedure. Results A total of 69 patients underwent one or more invasive procedures for hiccups (144 total procedures). Fifty-nine patients (86%) were men. The most frequent initial procedure was a phrenic nerve block (n=10) followed by oesophageal dilation (n=9). Only 31 patients (45%) manifested hiccup palliation after their first procedure. Nearly half, or 32 patients (46%), underwent more than one procedure (2 underwent nine procedures). Of these subsequent procedures, 35 resulted in palliation. Five adverse events arose from 144 procedures: post-esophagectomy atrial fibrillation, haematoma after cardiac device removal, vocal cord immobility after craniotomy, vocal cord immobility after vagal nerve manipulation, and a cerebral spinal leak after vagal nerve decompression. Conclusions Invasive procedures can palliate hiccups with an acceptable safety profile. However, these procedures appear to palliate hiccups in only about half of patients and sometimes do so only transiently.
