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.

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.

Background: Patients who experience homelessness manifest poor cancer outcomes, often because of treatment delays. Few studies have used mixed methods to learn what happens at the patient and health care staff level to explain these delays. Methods: This single-institution, multi-site study interrogated the entire medical record system (thousands of patients annually) for homelessness and cancer diagnoses from January 1, 2019, through October 10, 2023. Records were abstracted for relevant quantitative and qualitative data; rigorous methods were used to analyze, integrate, and report findings. Results: Forty-three patients with a median age of 58 years (range: 32, 73 years) and 34 (79%) assigned male sex at birth are the focus of this report. The most common cancers include hematologic (n = 8), gastrointestinal (n = 8), and genitourinary (n = 8). Thirty-five patients (81%) initiated cancer therapy, and 27 (63%) manifested treatment delay (>4 weeks post-diagnosis). The median time to cancer therapy was 9 weeks (95% confidence interval: 4.6, 12 weeks). Qualitative themes that explain delays are as follows: (1) logistical challenges in communication between the patient and health care team (“lack of a cell phone”); (2) patient reluctance to receive care (“patient elected to leave Against Medical Advice”); and (3) medical challenges in providing care (“he was hospitalized after being found down and hypotensive”). Conclusions: This study confirms that initiation of cancer therapy is often delayed in patients who experience homelessness. It sheds light on reasons for delay – for example, lack of phone access, an observation which suggests that perhaps provision of a burner phone might help some patients.

e17538 Background: Adherence to guideline-consistent chemotherapy-induced nausea and vomiting (CINV) prophylaxis is suboptimal. The primary aim of this study was to evaluate the magnitude of compliance to institutional guideline-directed antiemetic prophylaxis using a computerized physician order entry system at a single tertiary care institution. A nurse survey was also performed to evaluate how oncology practices, within a cooperative group, manage clinician orders for the prevention of CINV. Methods: The electronic medical records of 100 consecutive patients were evaluated. The primary endpoint was the incidence of compliance to provide all aspects of institutional guideline-directed antiemetic prophylaxis for acute (Day 1) and delayed (Days 2-4) CINV for patients receiving high, moderate, low, and minimally-emetogenic chemotherapy (HEC/MEC/LEC/MinEC). Noncompliance was declared if a recommended antiemetic was not prescribed per the guidelines or if additional antiemetics were prescribed. Descriptive analyses were performed on the convenience sample. Logistic regression was applied to determine the association of potential factors with noncompliance. Results: The incidence of compliance on Days 1-4 was 94%. Half of the noncompliant events occurred on Day 1 alone and involved the omission of pre-chemotherapy prochlorperazine in patients receiving LEC (3 of 6, 50%). There was a high-degree of compliance to institutional guidelines for delayed CINV (97%). Patients receiving doxorubicin/cyclophosphamide were numerically less likely to receive institutional guideline-directed antiemetic prophylaxis, compared to patients receiving other chemotherapy regimens (OR: 0.24 (0.04, 1.36), p-value: 0.05). No other factors were significantly predictive for compliance. The nurse survey demonstrated significant variability amongst the involved institutions, with regards to antiemetic prescribing practices. Conclusions: Computerized physician order entry is associated with impressive adherence to clinician prescribing practices, according to institutional guideline-directed antiemetic prophylaxis, for preventing acute and delayed CINV.

9075 Background: Chemotherapy-induced peripheral neuropathy (CIPN), a common dose-limiting side effect of chemotherapy, remains without known effective interventions. Preliminary data support that Scrambler therapy, a device which treats pain via non-invasive cutaneous electrostimulation, is beneficial for the treatment of CIPN. This pilot trial was performed to investigate the effect of Scrambler therapy for the treatment of CIPN. Methods: Eligible patients included those age ≥18 years, ECOG PS ≤2, life expectancy ≥3 months, with pain or CIPN symptoms of ≥1 month duration and tingling or pain ≥4/10 during the prior week. Patients were treated with Scrambler therapy to the affected area for up to 10 daily 30 minute sessions. Symptoms were monitored daily during therapy using a questionnaire to measure symptoms of neuropathy with a numerical analogue scale. Results: We report on the first 11 CIPN patients, enrolled between 7/18/2011 and 12/12/2011, 3 men and 8 women; mean age 57 years. Patients had history of exposure to various chemotherapeutic agents and the majority had symptoms >2 years. The table portrays data at baseline, at the end of the 10 planned days of therapy, and the percent changes from baseline to the end of treatment, regarding patient reported pain, tingling, and numbness over the preceding 24 hours. There were no adverse events. Persistent benefit out to 5 weeks was seen in some patients; maturing data will be available by May 2012. Descriptive summary statistics formed the basis of data analysis. Further patients are being entered on this trial. Conclusions: Scrambler therapy appears to be beneficial in the treatment of CIPN. A prospective placebo-controlled clinical trial should be performed to confirm these preliminary findings. [Table: see text]
