e17549 Background: Ovarian cancer is the most lethal gynecologic cancer with roughly 20% of cases attributable to mutations in BRCA 1 or BRCA 2. In 2018, the SOLO-1 study, comparing PARPi to placebo in BRCA 1/2 mutated ovarian cancers following first-line chemotherapy showed an unprecedented 70% reduction in the hazard to progression or death. Consequently, in 2020, ASCO published a consensus statement recommending germline testing for all women with epithelial ovarian cancer. Currently, our understanding of the improvement, or lack thereof, in germline testing for ovarian cancers following these changes are not well described, and research is needed to determine the real-world frequency of and barriers to genetic testing. Methods: We retrospectively reviewed 115 patients’ charts with newly diagnosed ovarian cancer from 2012-2022 at Grady Memorial Hospital. An assessment of genetic testing was acquired, including genetic counseling referral frequency, attrition, somatic tumor testing, and mutated genes identified. Additional characteristics including age, race, histology, grade, and stage were obtained. Univariate association (Chi-square or Fisher’s exact test) was performed to correlate the above variables with germline testing. Results: Of 115 patients diagnosed with ovarian cancer from 2012–2022, 33% received a genetic counseling referral and 16.5% received an evaluation. Germline testing, in lieu of referral, was ordered by the physician in 20% of cases. Among patients who completed germline testing, a pathogenic mutation was found in 9.8% of patients. Patients who were ≤ 48 years old were more likely to be referred for genetic counseling (50% vs. 26.5%, p = 0.016), and those with earlier stage disease (stage 1 or 2 versus stage 3 or 4) were more likely to be referred for genetic counseling (46.5% vs. 25%, p = 0.018). There was a significant difference in those receiving genetic counseling referral pre and post October 2018 (when SOLO-1 was published) with 50% of patients being referred after October 2018 versus 18% of patient before referred prior (p = 0.005), and in 2021 (following the ASCO consensus statement), an impressive 63.6% of patients were referred with attrition rate of 54.5%. Conclusions: Our real-world data demonstrates improvement in germline testing for newly diagnosed ovarian cancers at our institution over the past decade, with significant increases in both genetic counseling referral and attrition since 2018. Despite these improvements, we continue to be deficient in testing patients who are older and with more advanced-stage disease, which may be due to the gravity of their presentation and prioritized focus of treatment initiation. System-wide changes, including the option of having genetic testing ordered by the oncologist in the clinic with genetic counseling performed after results are available, are being explored.
Abstract Background: This Phase II study aimed to determine the efficacy and safety of administering palliative radiotherapy (RT) to bone metastases (mets) in patients (pts) receiving concurrent palbociclib and hormone therapy (HT) for hormone receptor positive, Her2/neu negative breast cancer. The primary endpoint was response rate 3 months after RT. Methods: Pts with painful bone mets or asymptomatic bone mets with risk for impending clinical event were treated with RT to 30 Gy in 10 fractions or 20 Gy in 5 fractions with concurrent palbociclib and HT. Change in maximum pain score on the Brief Pain Inventory was used to assess pain response 3 months post RT relative to baseline. Among pts with asymptomatic bone lesions, response was defined as prevention of a clinical event (e.g., bone fracture) without evidence of local tumor growth on surveillance imaging. Patient reported outcomes (PROs) of fatigue, depression, anxiety, and quality of life were collected. Blood-based biomarkers were examined to determine their relationship with response and PROs. Using a non-inferiority study design, a sample size of at least 33 pts was needed to achieve 80% power to detect a non-inferiority proportion of 60% using a one-sided binomial test and assuming a Type I error of 0.05. Results: Among 38 patients enrolled, 79% had painful bone mets. 35 pts completed baseline and 3-month post RT assessments. 61% and 37% of pts received aromatase inhibitors and fulvestrant, respectively, with palbociclib. Median age was 60 years (31-83) and 25% of pts were non-Hispanic Black. The majority (72%) of pts received 5 fraction RT and 69% received RT to one bone region. 29 patients (83%) were responders [95% CI: 66%-93%, p=.003]. Median progression free survival (PFS) was 30.4 months (1.3 - 44.0). Three-year PFS and overall survival were 45.6% and 67.2%, respectively. Grade 3 neutropenia developed in 4 (11%), 4 (11%), and 7 (20%) pts at end of RT, 1 month, and 3 months post RT, respectively. No pts developed Grade 4 neutropenia. One patient developed Grade 3 gastrointestinal toxicity during RT, another developed Grade 3 dyspnea 1 month post XRT, and another developed a bone fracture 6 months after RT. >While patient reported measures of fatigue, depression, and overall quality of life did not significantly change during or after RT relative to baseline, pain scores (i.e., BPI pain severity and interference, BM22 pain characteristics and pain site subscales, EORTC C15 pain) significantly decreased 3 months post XRT relative to baseline. Heightened inflammatory marker levels (e.g., TNFRII, IL1ra, CRP, TNF alpha) were significantly associated with worse symptoms of fatigue (MFI) and depression (HADS), increased pain interference (BPI), and lower overall quality of life (SF-36), controlling for age and time using mixed effect models. Patients with improved pain symptoms and lower pain scores had significantly lower inflammatory marker levels relative to baseline (e.g., interleukin-6). Conclusions: Our study demonstrated high rates of response to concurrent RT with palbociclib and HT with acceptable levels of toxicity. These results suggest that RT to bone mets effectively alleviates pain in patients taking palbociclib and pain response to treatment is associated with decreased inflammatory markers. RT may be given to pts receiving palbociclib and HT for breast cancer.

PurposeAnal cancer affects a disproportionate percentage of persons infected with human immunodeficiency virus (HIV). We analyzed a cohort of patients with HIV and anal cancer who received modern radiation therapy (RT) and concurrent chemotherapy to assess whether certain factors are associated with poor oncologic outcomes.Patients and MethodsWe performed a retrospective chart review of 75 consecutive patients with HIV infection and anal cancer who received definitive chemotherapy and RT from 2008 to 2018 at a single academic institution. Local recurrence, overall survival, changes in CD4 counts, and toxicities were investigated.ResultsMost patients were male (92%) with large representation from Black patients (77%). The median pretreatment CD4 count was 280 cells/mm3, which was persistently lower at 6 and 12 months’ posttreatment, 87 cells/mm3 and 182 cells/mm3, respectively (P < .001). Most (92%) patients received intensity modulated RT; median dose was 54 Gy (Range, 46.8-59.4 Gy). At a median follow-up 5.4 years (Range, 4.37-6.21 years), 20 (27%) patients had disease recurrence and 10 (13%) had isolated local failures. Nine patients died due to progressive disease. In multivariable analysis, clinically node negative involvement was significantly associated with better overall survival (hazard ratio, 0.39; 95% confidence interval, 0.16-1.00, P = .049). Acute grade 2 and 3 skin toxicities were common, at 83% and 19%, respectively. Acute grade 2 and 3 gastrointestinal toxicities were 9% and 3%, respectively. Acute grade 3 hematologic toxicity was 20%, and one grade 5 toxicity was reported. Several late grade 3 toxicities persisted: gastrointestinal (24%), skin (17%), and hematologic (6%). Two late grade 5 toxicities were noted.ConclusionsMost patients with HIV and anal cancer did not experience local recurrence; however, acute and late toxicities were common. CD4 counts at 6 and 12 months’ posttreatment remained lower than pretreatment CD4 counts. Further attention to treatment of the HIV-infected population is needed.
The adoption of transoral robotic surgery and shifting epidemiology in oropharyngeal squamous cell cancer have stimulated debate over upfront and adjuvant treatment. Institutional variation in practice patterns can be obscured in patient-level analyses. We aimed to characterize institutional patterns of care as well as identify potential associations between patterns of care and survival.
Abstract BACKGROUND Differences in perception, assessment, communication, and management of pain contribute to racial/ethnic pain disparities in breast cancer (BC). We previously found that Black women (BW) reported higher pain severity and interference with life after breast surgery compared to White women after adjusting for type of surgery and other potential confounders. Racial/ethnic inequities persist despite prior trials to improve disparate pain outcomes. This is likely because multiple factors contribute to pain expression, and structural factors affect the ability to control pain adequately. Perceived discrimination is associated with mistrust of medical providers. These factors are known to affect clinical outcomes, but their impact on pain has been understudied. In this preliminary analysis, we examine medical discrimination, trust in physician, and pain outcomes among BW with early-stage breast cancer after mastectomy. METHODS We surveyed BW with stage 0-III breast cancer who had mastectomy < 2 years of study enrollment at Baylor St. Luke’s Medical Center or Harris Health Smith Clinic in Houston, TX. Participants completed a demographic survey as well as the Brief Pain Inventory (BPI), Discrimination in Medical Settings Scale (DMS), and Trust in Physician Scale (TPS). In the BPI, participants reported their pain severity (PS) on a 0-10 scale at its worst, least, and on average. They reported pain interference with life (PI) from 0-10, types of pain treatments, and % relief from pain treatments. DMS and TPS questions were assessed on 5-point Likert scale. We performed chart review to obtain baseline clinical data related to BC diagnosis and treatment and comorbidities. We summarized patients’ baseline demographic and clinical information using descriptive statistics. PI and DMS were scored as a mean of the total items of each survey. We created mean Trust and Mistrust scores using means of the TPS questions related to each category. RESULTS Of the 37 BW surveyed, 36 (97.3%) were non-Hispanic. 23 (62.2%) had HR+ BC, and 2 (6.7%) had HER2+ disease. 26 (70.3%) women received chemotherapy, 10 (27%) received radiation therapy, and 17 (45.9%) received endocrine therapy. 26 (70.3%) women had > 1 comorbidity; the mean (SD) number reported was 1.3 (1.1). Mean BMI was 30.9 (6.6). 10 (29.4%) women completed high school, and 8 (23.5%) completed some college. 19 (55.9%) had a household income < $25,000, and 11 (32.4%) had private health insurance. Mean worst PS was 4.2 (3.1), and mean average PS was 3.6 (2.9). Mean composite PI score was 2.7 (2.7). 11 (29.7%) women were taking opioids for pain, 17 (45.9%) were taking non-opioid analgesics, and 3 (8.1%) were receiving non-medication treatments. Mean % pain relief with treatment was 52.3% (38.3). Mean DMS score was 1.2 (0.6). Mean composite TPS Trust and Mistrust scores were 4.4 (0.7) and 1.8 (1.0), respectively. CONCLUSION BW may continue to experience pain requiring opioid and/or non-opioid analgesics up to 2 years following mastectomy. Study participants reported relatively low levels of discrimination and high levels of trust on average. We are currently enrolling additional participants in the Emory Healthcare System and Grady Memorial Hospital in Atlanta, GA. After enrolling at least 80 total patients, we will determine the association between DMS and pain outcomes among participants adjusting for demographic, socioeconomic, and clinical factors as well as assess TPS as a potential mediator in the causal pathway between DMS and PS.

e13751 Background: Racial pain disparities in breast cancer (BC) are well-described and persist despite prior trials to improve disparate pain outcomes. We previously found Black women (BW) reported more pain severity (PS) and interference with life (PI) after breast surgery compared to White women. Pain expression is multifactorial, and structural factors affect the ability to report and control pain. Perceived discrimination is associated with mistrust of medical providers, which affects clinical outcomes. Their impact on pain is understudied. We evaluated the association between discrimination, trust, and pain among BW with early-stage BC after mastectomy. Methods: BW with stage 0-III BC who had mastectomy ≤2 years of enrollment at academic and safety net hospitals in Houston, TX and Atlanta, GA, completed a demographic survey, Brief Pain Inventory (BPI), Discrimination in Medical Settings Scale (DMS), and Trust in Physician Scale (TPS). In BPI, worst, least, and average PS were reported from 0-10. PI from 0-10, pain treatments, and % relief were reported. DMS and TPS questions were on a 5-point Likert scale. We performed chart review to obtain baseline clinical data related to BC diagnosis, treatment and comorbidities. PI and DMS were scored as a mean of the total items of each survey. Mean Trust and Mistrust scores used means of TPS questions related to each category. Higher scores mean more PS, PI, discrimination, trust, or mistrust. We used ANOVA to examine associations between categorical variables and Pearson correlation coefficient for continuous variables. We performed univariate linear regression and multi-linear regression between specific variables and outcomes, accounting for collinearity. Results: Of the 77 BW surveyed, 66.2% received chemotherapy. 47.2% had a household income < $25,000, and 40.3% had private health insurance. PS, PI, DMS, and trust scores are shown (Table). Univariate analysis showed an association between DMS and mistrust (p=0.01), lower income and higher PS (p=0.01) and PI (p=0.04), and insurance status and PS (p=0.02) and PI (p=0.02). Associations between mistrust or DMS and pain were not statistically significant. A multivariate analysis with DMS as outcome showed an association with mistrust (p=0.04). Multivariate analysis also showed receipt of chemotherapy was associated with higher PS (p=0.02) and PI (p=0.03). Conclusions: BW have moderate pain up to 2 years following mastectomy. Participants reported low levels of discrimination and high trust. More discrimination was associated with more physician mistrust, but not PS or PI. Lower income and lack of private health insurance were associated with higher PS and PI. Future studies should address discrimination and trust in clinical settings and financial barriers to pain control. [Table: see text]
Incidence of surgical site infection (SSI) following Mohs micrographic surgery (MMS) amongst patients with diabetes is largely unknown.Evaluate diabetes as a potential SSI risk factor in MMS by comparing SSI incidence in a cohort of patients with and without diabetes.A 5-year retrospective review to determine SSI rate in patients with diabetes compared to patients without diabetes. SSI incidence in patients with diabetes was further compared by A1c, and the impact of antibiotics on SSI rate was also examined.Overall rate of SSI was 1.47% (53/3597 cases). SSI rate amongst patients with diabetes was 1.95% (14/719 cases) compared to 1.35% (39/2878 cases) in patients without diabetes, with a non-significant odds ratio for SSI of 1.45 (95% CI = 0.78-2.68, P = 0.241). Multivariable logistic regression analysis revealed no difference in SSI. Stratification of diabetic patients by A1c into ≥7.0 and <7.0 compared to patients without diabetes yielded no statistically significant difference in SSI amongst all groups (P = 0.815). Whether an antibiotic was prescribed did not significantly impact SSI rate between groups.No significant difference in postoperative SSI was found in patients with diabetes compared to patients without diabetes following MMS regardless of degree of glycaemic control.
