Background: Traditional citation-based metrics do not capture the dissemination of upper extremity lymphedema (UEL) research that occurs online and in mainstream media. There is limited literature reporting the most impactful UEL articles based on citation rate and/or online mentions. We sought to use the Altmetric Attention Score (AAS) to determine the most impactful UEL articles in online media and to report trends in the diagnosis, treatment, and prevention of complications. Methods: The Altmetric database was queried to identify all published articles regarding the management, diagnosis, and prevention of complications seen in the setting of UEL. Extracted data points included article topic and type, journal, and number of online mentions on several platforms. Results: Our index search yielded 638 studies published between 2000 and 2021. Fifty articles with the highest AAS scores were included for analysis. The median AAS was 27.5, but the top four articles had AAS scores that were substantially higher (AAS ≥ 334) than all other studies. Of the top 50 articles, 68% (34/50) were original research. Of those, 23.5% (8/34) were randomized control trials. The most common article topic was the treatment of UEL (36%; 18/50) followed by diagnostic methods of UEL (30%; 15/50). There were a total of 1156 Twitter mentions (median:14) for the top 50 articles. Of all media platforms, news mentions correlated most strongly with AAS (R 2 = 0.99, P < 0.001). Conclusions: Our findings suggest that alternative metrics measure distinct components of article impact and add an important dimension to understanding the overall impact of published research on UEL.

Background Intraoperative radiation therapy (IORT) in select populations is a viable alternative to whole breast radiation therapy (WBRT) in the treatment of biopsy-proven localized invasive and non-invasive breast cancer. We aim to assess recurrence and complication rates following IORT in lumpectomy patients at a community hospital in Baltimore City. Methods An IRB-approved retrospective cohort study was conducted on consecutive cases of lumpectomy with IORT from 2013 through 2020 by a single surgeon. Patient demographics, tumor and operative characteristics, and complications were retrieved from electronic medical records. Primary outcomes were postoperative complications and local recurrence rates. Results The final cohort included 117 patients with mean follow-up time of 2.60 + 1.78 years. Mean age was 69.84 + 8.77 years. Thirty-three (28.21%) of patients developed a seroma. Odds of seroma formation were mildly significant for skin spacing [OR: 1.18, 95% CI: (1.02-1.37)] and balloon fill volume [1.04 (1.00-1.08)], but not for age, BMI, diabetes, former or current smoking status, history of WBRT, tumor size, or balloon size. Three (2.6%) patients had local recurrence. Odds of local recurrence were mildly significant for increased tumor size [1.14 (1.04-1.24)] and not significant for any other covariates. Conclusions IORT exposure did not confer higher rates of complications and the local recurrence rate mirrored that of the general population undergoing lumpectomy and WBRT. This study demonstrates the need for equitable treatment options based on individual needs: IORT is a safe alternative to WBRT in certain subpopulations, especially those with physical, social, or personal limitations preventing participation in a 3- to 7-week time commitment of WBRT.
