Abstract Background Radiation‐associated soft tissue sarcomas (RA‐STS) are rare complications of patients receiving radiation therapy (RT) and are generally associated with a poor prognosis. Most of the literature surrounding RA‐STS of the chest is centered on angiosarcoma. Therefore, we aim to document the management and outcome of patients with non‐angiosarcoma RA‐STS of the chest. Methods We reviewed 17 patients (all female, median age 65 years) diagnosed with RA‐STS. The most common primary malignancy was breast carcinoma ( n = 15), with a median RT dose of 57.9 Gy. All patients underwent surgical resection; five patients (29%) received radiotherapy; and five patients (29%) received peri‐operative chemotherapy. Results The 5‐year local recurrence and metastatic‐free survival were 61% and 60%, while the 5‐year disease‐specific survival was 53%. Local recurrence was associated with death due to disease (HR 9.06, p = 0.01). Complications occurred in nine of patients, most commonly due to a wound complication ( n = 7). At the most recent follow‐up, the median Musculoskeletal Tumor Society Score was 63%. Conclusion RA‐STS involving the chest wall are aggressive tumors with a high risk of local relapse and death due to disease. Local recurrence was associated with death due to disease; as such, we recommend aggressive surgical management with evaluation for adjuvant therapies.

Context.— The joint College of American Pathologists/American College of Medical Genetics and Genomics Cytogenetics Committee works to ensure competency and proficiency of clinical cytogenetics testing laboratories through proficiency testing programs for various clinical tests offered by such laboratories, including the evaluation of constitutional abnormalities. Objective.— To review and analyze 20 years of constitutional chromosome analysis proficiency testing results (2003–2022), primarily utilizing G-banded karyograms. Design.— A retrospective review of results from 2003 through 2022 was performed, identifying challenges addressing constitutional disorders. The chromosomal abnormalities and overall performance were evaluated. Results.— A total of 184 cases from 161 proficiency testing challenges were administered from 2003 through 2022. Challenges consisted of metaphase images and accompanying clinical history for evaluation of numerical and/or structural abnormalities. Of the 184 cases, only 2 (1%) failed to reach an 80% grading consensus for recognition of the abnormality. Both cases illustrated the limitations of correctly characterizing some chromosomal abnormalities, including recombinant chromosomal abnormalities and isochromosome identification. In addition, 2 cases failed to reach a consensus for nomenclature reporting: 1 with an isochromosome and another with a duplication. Conclusions.— This 20-year review illustrates the high rate of competency and proficiency of cytogenetic laboratories in the correct identification of constitutional chromosome abnormalities.

e23554 Background: Follicular dendritic cell sarcoma (FDCS) is a low-grade neoplasm arising from follicular dendritic cells. Its diagnosis is challenging due to its extreme rarity, and the optimal management remains unknown. Methods: We conducted a retrospective study of FDCS patients (pts) seen at Mayo Clinic, MN since 2018. Time to event analyses were done from the time of diagnosis. Results: Ten pts with FDCS were identified (Table). The median age was 60 years (range, 38-76) and 5 were males. Abdominal pain was the most common presenting symptom (30%) followed by constitutional symptoms, shortness of breath, and vision change. In 3 pts, the diagnosis was incidental. The 2 most common primary locations were abdomen/pelvis (50%) and mediastinum (30%). Six pts (60%) presented with advanced disease and 3 (30%) had Castleman’s disease. Most (60%) had advanced disease. Six pts had Epstein-Barr virus in situ hybridization and all tested negative. Seven pts had next generation sequencing and 5 (83%) had genetic alterations detected with CDKN2A/B alterations being most frequent (3 pts, all with advanced disease). The median follow up was 4.3 years (range, 0.2-13.3). In the 4 patients with localized disease, 3 underwent complete surgical excision resulting in complete remissions (CRs). The one who received radiation had a partial remission (PR). The median time to progression after 1st line treatment was 4 months (all with advanced disease). All 3 pts who died had advanced disease and 2 had CDKN2A/B alterations. Conclusions: In FDCS, localized diseases managed by surgical excision with or without radiation can achieve long term remissions. Advanced diseases generally do not respond to multimodality therapy including immunotherapy but can have disease stabilization with variable survival. CDKN2A/B mutations were common and potentially associated with a worse outcome. Better understanding of the impact of the FDCS mutational landscape on prognosis may provide novel approaches to therapy. [Table: see text]

This study investigates delays in transitioning from positive noninvasive multitarget stool DNA test results to scheduled diagnostic colonoscopies and identifies strategies aimed at improving patient care. A retrospective review revealed a 53% reduction in the average time from positive multitarget stool DNA test results to ordering colonoscopies postintervention. The findings demonstrate the significance of implementing a new communication system to expedite transitions in health care processes, showcasing its potential to significantly improve efficiency in patient care and health care provider workflows across various clinical testing scenarios. The findings emphasize the transformative impact of this communication system, shedding light on its ability to streamline processes and enhance patient care and staff experience.

Abstract Background: Eyebrow and eyelash loss, known as madarosis, can occur secondary to breast cancer-directed therapy. However, the incidence and predictors of this phenomenon are not well-known. The purpose of this study is to ascertain the proportion of breast cancer survivors who experience madarosis, potential contributing factors to eyebrow and eyelash loss, and associations between this symptom and mental health. Methods: Breast cancer survivors were invited to participate in an ongoing longitudinal cohort study, the Mayo Clinic Breast Disease Registry (MCBDR), after having been seen at least once for breast cancer at Mayo Clinic in Rochester, MN. Those who consented were mailed a survey approximately one year after diagnosis. Respondents were asked to report their degree of eyebrow and eyelash loss experienced since their diagnosis on a 4-point scale of “no loss” (0) to “complete loss” (3). The proportions of participants who reported eyebrow and eyelash loss were evaluated overall and according to treatment type by descriptive statistics. Relationships between eyebrow and eyelash loss and mental health scores collected using the PROMIS-10 project scales (ranging from 0-20), with the poorest mental health indicated by scores under 8, were explored. Results: 838 registry participants responded to the year 1 survey’s alopecia questions. The median age of breast cancer survivors was 59.4 years (range 22-100 years). The majority were diagnosed at stage I-II (69%). 315 (37%) had received chemotherapy (+/- endocrine therapy), 415 (50%) had received endocrine therapy only, and 108 (13%) had received neither. Nearly half reported eyebrow loss (49%) or eyelash loss (49%). Eyebrow loss was reported by 89% of chemotherapy recipients, 27% of endocrine therapy only recipients, and 19% of those not treated with chemotherapy or endocrine therapy. 102 (32%) of those with chemotherapy-associated eyebrow loss reported that it was complete. Eyelash loss was reported by 274 (87%) of chemotherapy recipients, 112 (27%) of endocrine therapy only recipients, and 23 (21%) of those who received neither. Although no formal statistical testing was performed, there was a numerically higher proportion of patients with eyebrow and/or eyelash loss who reported poor mental health. Conclusions: Madarosis is a bothersome symptom in cancer survivors, particularly after chemotherapy. Future investigation into the incidence, predictors, and treatment of anti-neoplastic medication-related madarosis is needed. Table.

Abstract Background: Retrospective studies suggest that breast cancer survivors report treatment-associated hair loss or thinning years after their initial diagnosis. This study investigates patient perceptions of alopecia persisting 6 years after the diagnosis of breast cancer. Methods: Breast cancer survivors who had signed informed consent for participation in a prospective longitudinal cohort study, the Mayo Clinic Breast Disease Registry (MCBDR), after diagnosis of breast cancer approximately six years prior, were mailed a survey. This survey asked about degree of bother from hair thinning and hair loss on a scale from 0 “not at all” to 4 “extremely” and about use of hair thickening/regrowth products. PROMIS-10 project scales assessed global mental health (5: worst mental health, 20: best mental health). Data were analyzed using descriptive statistics. Results: 969/1476 participants responded (response rate 65.7%); 819 participants were available for analysis. Participant median age was 65.7 years (range 34 -100 years). 604 (73%) had been diagnosed with stage I-II breast cancer, 248 (30%) had received chemotherapy (+/- endocrine therapy), 365 (45%) had received only endocrine therapy, and 206 (25%) had received neither. Nearly half (381, 47%) reported hair loss and over half (468, 57%) reported hair thinning. 155 (19%) used hair regrowth products. Amongst the 526 who were 55 years and older, 270 (51%) reported hair loss and 323 (61%) hair thinning; 111 (38%) of the 291 women under 55 years reported hair loss and 145 (50%) hair thinning. Twenty-eight percent of chemotherapy recipients, 18% of patients who did not receive chemotherapy but received endocrine therapy, and 14% of patients who had received neither reported continued difficulty with moderate to extreme hair loss. Moderate to extreme bother from hair thinning was reported by 34% of chemotherapy recipients, 22% of endocrine therapy-only recipients, and 18% of those who had received neither. See the table for associations between mental health scores and hair loss/thinning. Use of hair growth products was reported by 29% of chemotherapy recipients, 14% of endocrine therapy-only recipients, and 15% of those who had received neither oncologic therapy. Conclusions: Hair loss and thinning are frequently reported as persistently bothersome symptoms from breast cancer survivors. Future investigations into the incidence, predictors, and treatment of chemotherapy and endocrine therapy-associated alopecia are needed.

ImportanceRedirection of care refers to withdrawal, withholding, or limiting escalation of treatment. Whether maternal social determinants of health are associated with redirection of care discussions merits understanding.ObjectiveTo examine associations between maternal social determinants of health and redirection of care discussions for infants born extremely preterm.Design, Setting, and ParticipantsThis is a retrospective analysis of a prospective cohort of infants born at less than 29 weeks’ gestation between April 2011 and December 2020 at 19 National Institute of Child Health and Human Development Neonatal Research Network centers in the US. Follow-up occurred between January 2013 and October 2023. Included infants received active treatment at birth and had mothers who identified as Black or White. Race was limited to Black and White based on service disparities between these groups and limited sample size for other races. Maternal social determinant of health exposures were education level (high school nongraduate or graduate), insurance type (public/none or private), race (Black or White), and ethnicity (Hispanic or non-Hispanic).Main Outcomes and MeasuresThe primary outcome was documented discussion about redirection of infant care. Secondary outcomes included subsequent redirection of care occurrence and, for those born at less than 27 weeks’ gestation, death and neurodevelopmental impairment at 22 to 26 months’ corrected age.ResultsOf the 15 629 infants (mean [SD] gestational age, 26 [2] weeks; 7961 [51%] male) from 13 643 mothers, 2324 (15%) had documented redirection of care discussions. In unadjusted comparisons, there was no significant difference in the percentage of infants with redirection of care discussions by race (Black, 1004/6793 [15%]; White, 1320/8836 [15%]) or ethnicity (Hispanic, 291/2105 [14%]; non-Hispanic, 2020/13 408 [15%]). However, after controlling for maternal and neonatal factors, infants whose mothers identified as Black or as Hispanic were less likely to have documented redirection of care discussions than infants whose mothers identified as White (Black vs White adjusted odds ratio [aOR], 0.84; 95% CI, 0.75-0.96) or as non-Hispanic (Hispanic vs non-Hispanic aOR, 0.72; 95% CI, 0.60-0.87). Redirection of care discussion occurrence did not differ by maternal education level or insurance type.Conclusions and RelevanceFor infants born extremely preterm, redirection of care discussions occurred less often for Black and Hispanic infants than for White and non-Hispanic infants. It is important to explore the possible reasons underlying these differences.
