Objectives Evaluate the value of ultrasound specialist assessment of ovarian masses over 50 mm with sonograms interpreted as possible hemorrhagic ovarian cysts (HOC). Methods Retrospective review of consecutive endovaginal pelvic US reports of premenopausal women at one organization identified adnexal masses over 50 mm maximum diameter designated as possibly being HOC (large HOC). Four ultrasound specialists reviewed studies, scoring two assessments as true or false: 1) US features are most consistent with either an ovarian hemorrhagic cyst (HOC) or endometrioma; 2) If assessment 1 was true, the mass meets O‐RADS criteria of classic HOC except for size. Results A total of 457 of 51,305 women (0.9%) had reports indicating possible large HOC. For 366 patients with established outcomes, 225 (61.5%) had a large HOC (87.1% ≤ 70 mm). Assessment 1 was true for 318 patients; outcomes showed 224 (70.4%) HOC, 89 (28.0%) endometriomas, 4 (1.3%) TOAs, and 1 (0.3%) cystadenoma. Assessment 1 was false for 48 patients; outcomes showed 1 (2.1%) HOC, 1 (2.1%) endometrioma, 6 (12.5%) other non‐neoplastic cysts, 33 (68.8%) benign neoplasms, 5 (10.4%) borderline tumors, and 2 (4.2%) high‐grade malignancies. The decrease in neoplasms and malignancies with true assessment 1 was significant ( p < .001). Assessment 2 was true for 190 patients (180 [94.7%] HOC, 9 [4.7%] endometrioma, 1 [0.5%] cystadenoma), false for 128 patients (44 [34.4%] HOC, 80 [62.5%] endometrioma, and 4 [3.1%] TOA) ( p < .001), and not applicable for 48 patients. Conclusions Ultrasound specialist review of adnexal masses designated as a possible large HOC adds value since over 10% are neoplasms (nearly 2% malignant). Ultrasound specialist assessment can expedite additional imaging or intervention when necessary and obviate follow‐up when HOC features are typical.

Abstract Background Cryoprecipitated antihemophiliac factor (cryo) is primarily used to replenish fibrinogen in acquired coagulopathy. Little has been reported about its usage patterns within hospitals with respect to patient population, frequency of use, and dosing. Study design and methods Cryo production and usage data were collected over 5 years from July 1, 2016, to June 30, 2021, from nationally based blood collection centers in the United States (U.S. n = 2) and Canada ( n = 2) and from eight large academic hospitals, respectively. Usage data for a similar product, purified fibrinogen concentrate were also collected from four hospitals. Results Two U.S. blood collectors reported increases in cryo production normalized to total whole blood collections from 17.4% in 2016 to 22.3% in 2021 and from 16.4% in 2016 to 20.2% in 2021. In contrast, in Canada cryo manufacturing increased slightly in one region (11.3%–12.9%) and decreased (8.0%–2.0%) in the other. Cryo utilization, defined as numbers of patients treated normalized to the inpatient census, and dose administered per patient did not consistently increase and differed significantly between hospitals participating in the study ( p < .0001). Likewise, the departments that most frequently transfused cryo varied between hospitals. Similarly, variations in practice were observed for fibrinogen concentrate usage. Conclusion While much of Canada and Europe have moved towards using fibrinogen concentrate, two large U.S. collectors have increased cryo distribution. The lack of standardization and variability in the clinical practice regarding the use of cryo and fibrinogen concentrate reported by study sites may be attributable to practitioner preference, availability, and/or cost rather than adherence to published evidence or guidelines.

PURPOSE Given the extended survivorship of young adults with breast cancer, characterizing health care utilization and adherence to surveillance guidelines can inform gaps in care. PATIENTS AND METHODS Patients age 40 years and younger at diagnosis of stage 0-III breast cancer enrolled in a prospective cohort study completed a survey 7 years after diagnosis assessing receipt of care and surveillance. We evaluated factors associated with transition to a primary care provider (PCP) for cancer-related follow-up and adherence to mammography and bone density scans. RESULTS Among 660 women, 92% reported having a PCP, although for cancer-related follow-up, 57% saw only an oncology provider, 29% saw both a PCP and oncology provider. In the past 2 years, 68% reported getting a flu shot, 76% a pap test/pelvic examination, 56% cholesterol screening, and 42% (n = 232 endocrine therapy [ET] users) a bone density scan. Among women who had a unilateral mastectomy or lumpectomy (n = 356), 82% reported a mammogram in the past year. In multivariate analyses, those with stage 0 ( v I disease) were more likely to see a PCP for follow-up ( v PCP + oncology provider); ET users and those more concerned about recurrence were less likely. Patients with human epidermal growth factor receptor 2-positive (HER2) disease were more likely to adhere to mammography; those with a BRCA mutation and those with a unilateral mastectomy were less likely. Patients with a BRCA mutation and who had chemotherapy were more likely to report a bone density scan. CONCLUSION Although most have a PCP, over half of young survivors continue to see an oncology provider for follow-up in long-term survivorship. Mammography uptake was high; uptake of other health maintenance practices was lower. Identification of barriers/facilitators to receipt of guideline-concordant care may inform strategies to optimize survivorship.

ABSTRACT Objectives To characterize practice patterns and outcomes in the management of low‐ and intermediate‐grade salivary gland carcinoma prior to the existence of treatment guidelines. Methods Analysis of a registry of patients who underwent parotid and submandibular gland resections for low‐and intermediate‐grade carcinomas between 2010 and 2019. Results Of all 786 patients included in the study, 726 (92%) had preoperative imaging and 653 (83%) had preoperative biopsy. Of the 729 patients with parotid gland cancer, the majority underwent superficial ( n = 384, 53%) or total ( n = 254, 35%) parotidectomy. In patients with facial nerve preservation, total parotidectomy was associated with a significant increase in transient facial weakness (72/177 (41%) vs. 82/311 (26%), RR 0.65, 95% CI 0.50–0.84, p < 0.05) and permanent facial nerve weakness (23/176 (13%) vs. 16/301 (5%), RR 0.41, 95% CI 0.22–0.75, p < 0.05) compared to superficial parotidectomy. Adjuvant radiation therapy ( RT ) was delivered to 285 (36%) patients. The proportion of patients receiving adjuvant RT declined significantly over the time period from 2015 to 2019 compared to 2010 to 2014 at 162/504 (32%) and 123/282 (44%), respectively ( RR 0.74, 95% CI 0.61–0.89, p < 0.05). When comparing the time periods from 2015 to 2019 and 2010 to 2014, there was no significant difference in local control rates ( RR 0.52, 95% CI 0.26–1.04, p = 0.06) or regional control rates ( RR 0.75, 95% CI 0.26–2.13, p = 0.58). Conclusions Management of low‐ and intermediate‐grade salivary cancer from 2010 to 2019 was variable, which is expected given the rarity and heterogeneity of the disease and the lack of treatment guidelines prior to 2021. Most patients with parotid malignancies underwent superficial or total parotidectomy. The extent of parotidectomy had an impact on facial nerve function outcomes. Delivery of adjuvant radiation trended down with time. The data presented here will support dissemination of the guidelines and provide data that could inform future trials. Level of Evidence 2b.

Abstract Background Lung adenocarcinoma in never-smokers is a major public health burden, especially among East Asian women. Polygenic risk scores (PRSs) are promising for risk stratification but are primarily developed in European-ancestry populations. We aimed to develop and validate single- and multi-ancestry PRSs for East Asian never-smokers to improve lung adenocarcinoma risk prediction. Methods PRSs were developed using genome-wide association study summary statistics from East Asian (8002 cases; 20 782 controls) and European (2058 cases; 5575 controls) populations. Single-ancestry models included a PRS with 25 single nucleotide variants (PRS-25), PRS clumping and thresholding (CT), and LDpred2; multi-ancestry models included LDpred2 plus European PRS-128, PRS-CSx, and clumping and thresholding, super learning, empirical Bayes (CT-SLEB). Performance was evaluated in independent East Asian data from the Female Lung Cancer Consortium and externally validated in the Nanjing Lung Cancer Cohort. We assessed predictive accuracy via area under the curve operating procedure (AUC), with 10-year and (ages 30-80 years) absolute risks estimates. Results The best multi-ancestry PRS, using East Asian and European data via CT-SLEB, outperformed the best East Asian-only (LDpred2; AUC = 0.629, 95% confidence interval [CI] = 0.618 to 0.641), achieving an AUC of 0.640 (95% CI = 0.629 to 0.653) and odds ratio of 1.71 (95% CI = 1.61 to 1.82) per standard deviation increase. Nanjing Lung Cancer Cohort validation confirmed robust performance (AUC = 0.649, 95% CI = 0.623 to 0.676). The top 20% PRS group had a 3.92-fold higher lung adenocarcinoma risk than the bottom 20%. Further, the top 5% PRS group reached a 6.69% lifetime absolute risk. Notably, this group reached the average population 10-year lung adenocarcinoma risk at age 50 years (0.42%) by age 41 years, 9 years earlier. Conclusions Multi-ancestry PRS approaches enhance lung adenocarcinoma risk stratification in East Asian never-smokers, with consistent external validation, suggesting future clinical utility.

Background: Ischemic stroke remains a leading cause of morbidity and mortality worldwide. Cardioembolic sources account for a significant proportion of these events, necessitating accurate identification of underlying structural heart abnormalities. Traditionally, transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) have been utilized for this purpose, although both have limitations. Cardiac computed tomography (CCTA) has emerged as a potential alternative, offering non-invasive imaging with high sensitivity and specificity for detecting intracardiac thrombi. Objective: This study aimed to evaluate the diagnostic yield of CCTA compared to TTE and TEE in detecting high-risk cardioaortic sources of embolism, including left ventricular (LV) thrombus, left atrial (LA) thrombus, valvular thrombus, and ulcerated aortic plaques, in patients with ischemic stroke. Methods: We conducted a retrospective, single-center cohort study at Mayo Clinic, Rochester, MN, including 426 ischemic stroke patients who underwent CCTA within 30 days of stroke onset between March 2019 and June 2023. We compared the diagnostic yields of CCTA, TTE, and TEE in detecting structural cardiac sources of embolism. Results: The overall diagnostic yield of CCTA for detecting high-risk cardioaortic sources was 15.5%. Specifically, CCTA identified LV thrombus in 2.3% of patients, LA thrombus in 4.0%, valvular thrombus in 2.8%, and ulcerated aortic plaques in 7.0%. In comparative analysis, CCTA demonstrated a higher yield than TTE (16.0% vs 3.5%, p < 0.001) and a comparable yield to TEE (25.3% vs 20.7%, p = 0.47) in detecting these sources. Conclusions: CCTA proved to be a viable option for identifying high-risk structural sources of cardioembolism in ischemic stroke patients. Its non-invasive nature, coupled with the ability to perform imaging soon after stroke onset, underscores its clinical utility. However, further prospective and blinded studies are required to validate these findings and fully establish the efficacy of CCTA in this context.
