032) and fixator groups (4% vs 96%, p=0.021). The mean time period between injury and definitive surgery was significantly shorter in the external fixator group (11±5 vs 7±4 days, p=0.033). Before definitive treatment, pin tract infection was observed in two ankles in the fixator group.

Splint immobilization of ankle fracture-dislocations may predispose to reduction loss, soft tissue complications, and a longer time period between injury and definitive fixation. The risk of these potential complications can be reduced with the use of an external fixator.

Reducing the rate of margin positivity and reoperations remains a paramount goal in breast-conserving surgery (BCS). This study assesses the effectiveness of standard partial mastectomy with cavity shave margins (CSM) compared with partial mastectomy with selective margin resection (SPM), with regard to outcomes of the initial surgeries, re-excisions, and overall costs.

This is a retrospective review of 122 eligible breast cancer patients who underwent BCS at one institution. The CSM and SPM groups each included 61 patients, matched for presurgical diagnoses and clinical stage. Data including margin status, rates and reason for re-excision, associated operation times, and costs were analyzed.

Patients undergoing CSM had less than half the rate of positive margins (PMs) (10% vs. 23%; P=.03) and re-excisions (8% vs. 23%; P=.02) compared with SPM. In the former group, the margin involvement was focal, and re-excisions were performed almost exclusively for PMs. For SPM, the majority (92%) of PMs were on the main lumpectomy specimen rather than the selective margins, and re-excisions included, in addition to PMs, extensive or multifocal negative but close margins. Reduced breast tissue volumes were removed with CSM, particularly for patients undergoing a single surgery (47 vs. 165 cm
; P < .001). The initial surgery with CSM is on average 27% more costly than that for SPM (P < .001), due to the increased pathology costs which are partially offset by the increased re-excision rates in SPM.

Circumferential cavity shaving, associated with consistent lower PMs, tissue volumes excised, and re-excision rates, is appropriate for routine implementation as a method offering superior surgical outcomes.

Poor adherence to the 2011 American Society for Radiation Oncology (ASTRO) evidence-based guideline on whole-breast irradiation (WBI) has been reported. We utilized theMednet to assess the views of the updated 2018 guideline among radiation oncologists (ROs).

We identified 11 questions asked by community ROs on theMednet, a web-based platform, between October 27, 2014 and May 2, 2017 that were updated in the 2018 guideline. New answers provided by senior authors of the 2018 guideline, cited guidelines, and polls to survey ROs were disseminated in 3 theMednet's newsletters between March 16, 2018 and May 1, 2018. Any question with less than 60% consensus was resubmitted on October 9, 2019 and assessed on February 13, 2020.

A total of 792 ROs responded to the initial surveys. In each survey, the answer choice(s) that received the majority of the votes aligned with the 2018 guideline. The strongest consensus was for the use of hypofractionated (HF)-WBI regardless of histology (97%), followed by HF-WBI boost dose (92%), molecular subtype (90%), grade (88%), and concurrent use of trastuzumab (87%). The least consensus was for age at which HF-WBI should be offered with 53% of respondents, specifically 73% of academic ROs versus 47% of community ROs (P=.001), agreeing with the guideline. The re-submitted survey 19 months later showed 77% of 287 new respondents now agreed with the guideline regarding age.

The majority of ROs concur with the 2018 WBI guideline in theMednet surveys, with better agreement among academic ROs than community ROs for certain components of the guideline. Further research into the different practice patterns may optimize patient care.

Primary graft dysfunction (PGD) is a risk factor for chronic lung allograft dysfunction (CLAD). However, the association between PGD and degree of allograft injury remains poorly defined. In this study, we leverage a novel biomarker for allograft injury, percentage donor-derived cell-free DNA (%ddcfDNA), to study the association between PGD, degree of allograft injury, and the development of CLAD.

This prospective cohort study recruited 99 lung transplant recipients and collected plasma samples on days 1, 3, and 7 for %ddcfDNA measurements. Clinical data on day 3 was used to adjudicate for PGD. %ddcfDNA levels were compared between PGD grades. In PGD patients, %ddcfDNA was compared between those who developed CLAD and those who did not.

On posttransplant day 3, %ddcfDNA was higher in PGD than in non-PGD patients (median [IQR] 12.2% [8.2, 22.0] vs 8.5% [5.6, 13.2] p = 0.01). %ddcfDNA correlated with the severity grade of PGD (r = 0.24, p = 0.02). Within the PGD group, higher levels of %ddcfDNA correlated with increased risk of developing CLAD (log OR(SE) 1.38 (0.53), p = 0.009). PGD patients who developed CLAD showed ∼2-times higher %ddcfDNA levels than patients who did not develop CLAD (median [IQR] 22.4% [11.8, 27.6] vs 9.9% [6.7, 14.9], p = 0.007).

PGD patients demonstrated increased early posttransplant allograft injury, as measured by %ddcfDNA, in comparison to non-PGD patients, and these high %ddcfDNA levels were associated with subsequent development of CLAD. This study suggests that %ddcfDNA identifies PGD patients at greater risk of CLAD than PGD alone.
