Cancer survivorship programs at the Dana-Farber Cancer Institute.

PURPOSE: We sought to present the current status of survivorship programs at Dana-Farber Cancer Institute which include the David B. Perini, Jr. Quality of Life Clinic for survivors of childhood cancer, Stop and Shop Neuro-Oncology Outcomes Clinic for pediatric brain tumor survivors, and Adult Survivorship Program for adult cancer survivors including those diagnosed as adults (age 18 years and older) and adult survivors of childhood cancer, in an effort to share best practices as well as challenges. METHODS: Description of programs and discussion. RESULTS: Our institutional programs are detailed regarding their history and the multidisciplinary approach and both consultative and long-term care delivery models for pediatric and adult cancer survivors, with the goal of meeting the spectrum of survivorship care needs, from diagnosis and management of long-term effects of cancer-directed therapy and surveillance for subsequent cancer, to healthy lifestyle promotion and psychosocial support. Program investigators conduct research to understand the risks and unmet needs of cancer survivors, and to develop and test interventions to improve care delivery and medical and psychosocial outcomes. There are also educational initiatives detailed. CONCLUSIONS: Survivorship programs at Dana-Farber are designed to optimize care and outcomes for cancer survivors including conducting quality improvement initiatives and research to further understand and meet the clinical needs of the large, heterogenous, and growing population cancer survivors into the future. IMPLICATIONS FOR CANCER SURVIVORS: Programs like ours as well as those ongoing and planned aim to improve the comprehensive care of diverse cancer survivors.

Pectus repair after prior sternotomy: clinical practice review and practice recommendations based on a 2,200-patient database.

The minimally invasive repair of pectus excavatum (MIRPE) is widely accepted as a method of pectus excavatum (PE) repair. Repair is rarely performed in patients with a history of median sternotomy. A feared complication of this procedure is iatrogenic cardiac injury; the risk of injury in patients with prior sternotomy is especially high due to the development of post-surgical retrosternal adhesions, which obscures the "critical view" during MIRPE. A 14-center review reported the incidence to be as high as 7% after analyzing 75 patients with history of sternotomy who underwent MIRPE. Little literature exists on how to best prepare for MIRPE in patients with prior sternotomy. A review of the literature and a retrospective review of over 2,200 patients who underwent MIRPE at our institution was performed to analyze 9 patients who underwent MIRPE after prior sternotomy. Iatrogenic cardiac injury occurred in 2 patients. Given the infrequency in our experience and the low numbers reported in the literature, statistical conclusions cannot be drawn. However, prudent strategies based on this experience include thoracoscopy, routine sternal elevation, direct sub-xiphoid retrosternal dissection, coordination with cardio-thoracic surgeons, preparation for cardio-pulmonary bypass, and massive transfusion protocol availability to optimize surgical outcomes in patients undergoing MIRPE with a history of sternotomy.

Gastrointestinal Stromal Tumor in the Excluded Gastric Remnant After Roux-en-Y Gastric Bypass.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the GI tract. Despite this, they rarely occur, accounting for only 1% to 3% of all gastrointestinal tumors. This report describes a 53-year-old female patient with surgical history of Roux-en-Y gastric bypass (RYGB) who presented with right upper quadrant abdominal pain. CT imaging revealed a large 20 × 12 × 16 cm mass in the excluded stomach remnant. Ultrasound-guided biopsy confirmed this mass to be a GIST. The patient was treated surgically with exploratory laparotomy with distal pancreatectomy, partial colectomy, partial gastrectomy, and splenectomy. There are currently only 3 known reported cases of GISTs after RYGB.

Adrenocortical Carcinoma: Role of Adjuvant and Neoadjuvant Therapy.

Adjuvant and neoadjuvant chemotherapy in the treatment of adrenocortical carcinoma (ACC) is limited by few existing trials, most of which are retrospective. The drug mitotane has been used for the treatment of ACC, although existing guidelines only support its use in high risk of recurrence. The first phase 3 trial involving systemic chemotherapy for ACC supports the use of etoposide, doxorubicin, cisplatin, and mitotane for combination therapy. No significant breakthrough has been discovered thus far in of targeted and immunotherapies. Neoadjuvant chemotherapy is only used to allow for complete surgical resection because complete excision is the definitive treatment of ACC.

Association of Changes in Cancer Therapy Over 3 Decades With Risk of Subsequent Breast Cancer Among Female Childhood Cancer Survivors: A Report From the Childhood Cancer Survivor Study (CCSS).

Importance: Breast cancer is the most common invasive subsequent malignant disease in childhood cancer survivors, though limited data exist on changes in breast cancer rates as primary cancer treatments have evolved. Objective: To quantify the association between temporal changes in cancer treatment over 3 decades and subsequent breast cancer risk. Design, Setting, and Participants: Retrospective cohort study of 5-year cancer survivors diagnosed when younger than 21 years between 1970 and 1999, with follow-up through December 5, 2020. Exposures: Radiation and chemotherapy dose changes over time. Main Outcomes and Measures: Breast cancer cumulative incidence rates and age-specific standardized incidence ratios (SIRs) compared across treatment decades (1970-1999). Piecewise exponential models estimated invasive breast cancer and ductal carcinoma in situ (DCIS) risk and associations with treatment exposures, adjusted for age at childhood cancer diagnosis and attained age. Results: Among 11 550 female survivors (median age, 34.2 years; range 5.6-66.8 years), 489 developed 583 breast cancers: 427 invasive, 156 DCIS. Cumulative incidence was 8.1% (95% CI, 7.3%-9.0%) by age 45 years. An increased breast cancer risk (SIR, 6.6; 95% CI, 6.1-7.2) was observed for survivors compared with the age-sex-calendar-year-matched general population. Changes in therapy by decade included reduced rates of chest (34% in the 1970s, 22% in the 1980s, and 17% in the 1990s) and pelvic radiotherapy (26%, 17%, and 13% respectively) and increased rates of anthracycline chemotherapy exposures (30%, 51%, and 64%, respectively). Adjusting for age and age at diagnosis, the invasive breast cancer rate decreased 18% every 5 years of primary cancer diagnosis era (rate ratio [RR], 0.82; 95% CI, 0.74-0.90). When accounting for chest radiotherapy exposure, the decline attenuated to an 11% decrease every 5 years (RR, 0.89; 95% CI, 0.81-0.99). When additionally adjusted for anthracycline dose and pelvic radiotherapy, the decline every 5 years increased to 14% (RR, 0.86; 95% CI, 0.77-0.96). Although SIRs of DCIS generally increased over time, there were no statistically significant changes in incidence. Conclusions and Relevance: Invasive breast cancer rates in childhood cancer survivors have declined with time, especially in those younger than 40 years. This appears largely associated with the reduced use of chest radiation therapy, but was tempered by concurrent changes in other therapies.

Delphi Panel Consensus Recommendations for Screening and Managing Childhood Cancer Survivors at Risk for Cardiomyopathy.

Background: Cardiomyopathy is a leading cause of late morbidity and mortality in childhood cancer survivors (CCS). Evidence-based guidelines recommend risk-stratified screening for cardiomyopathy, but the management approach for abnormalities detected when screening asymptomatic young adult CCS is poorly defined. Objectives: The aims of this study were to build upon existing guidelines by describing the expert consensus-based cardiomyopathy screening practices, management approach, and clinical rationale for the management of young adult CCS with screening-detected abnormalities and to identify areas of controversy in practice. Methods: A multispecialty Delphi panel of 40 physicians with expertise in cancer survivorship completed 3 iterative rounds of semi-open-ended questionnaires regarding their approaches to the management of asymptomatic young adult CCS at risk for cardiomyopathy (screening practices, referrals, cardiac testing, laboratory studies, medications). Consensus was defined as ≥90% panelist agreement with recommendation. Results: The response rate was 100% for all 3 rounds. Panelists reached consensus on the timing and frequency of echocardiographic screening for anthracycline-associated cardiomyopathy, monitoring during pregnancy, laboratory testing for modifiable cardiac risk factors, and referral to cardiology for ejection fraction ≤50% or preserved ejection fraction with diastolic dysfunction. Controversial areas (<75% agreement) included chest radiation dose threshold to merit screening, indications for advanced cardiac imaging and cardiac serum biomarkers for follow-up of abnormal echocardiographic findings, and medical management of asymptomatic left ventricular systolic dysfunction. Conclusions: Expert practice is largely consistent with existing risk-based screening guidelines. Some recommendations for managing abnormalities detected on screening echocardiography remain controversial. The rationale offered by experts for divergent approaches may help guide clinical decisions in the absence of guidelines specific to young adult CCS.

Management of childhood cancer survivors at risk for thyroid function abnormalities: A Delphi study.

BACKGROUND: Thyroid function abnormalities can occur after treatment for childhood cancer. Evidence for the management of thyroid dysfunction among asymptomatic childhood cancer survivors (CCS) is lacking. We used a Delphi consensus methodology to expand guidelines for screening asymptomatic CCS at risk for thyroid dysfunction and explore recommendations for the clinical management of abnormal results. PROCEDURE: A Delphi panel of 40 expert physicians representing oncology, endocrinology, and primary care participated in three rounds of anonymous, iterative questionnaires formatted as clinical scenarios. Consensus is defined as ≥ 90% of panelists agree with recommendation and disagreement as < 70% agree. RESULTS: Panelists reached consensus that CCS treated with radiation including neck, total body, whole brain, brain including the hypothalamic-pituitary axis (HPA), and therapeutic meta-iodobenzylguanidine (MIBG) should have annual, lifelong screening using serum thyroid-stimulating hormone (TSH) and free T4 starting within one year off-treatment (98%). Panelists disagreed on continuing to screen CCS for thyroid dysfunction after immunotherapy associated with acute thyroid injury (31%-50%). There was also disagreement on indications for brain (17%-43%) or thyroid (50%-65%) imaging, laboratory tests to assess the HPA (29%-75%), and TSH threshold to initiate treatment of subclinical hypothyroidism. Lack of evidence was the most frequent rationale panelists offered for not recommending additional testing or medications. Panelists' recommendations did not vary by geography, specialty, or survivorship clinical experience. CONCLUSIONS: Consensus was reached on most recommendations for screening and management of cancer treatment-related thyroid dysfunction. Screening after completion of thyroid-toxic immunotherapy, indications for imaging, and treatment of subclinical hypothyroidism are areas of disagreement for further investigation.

Consensus Recommendations for Managing Childhood Cancer Survivors at Risk for Stroke After Cranial Irradiation: A Delphi Study.

BACKGROUND AND OBJECTIVES: There is insufficient evidence to support stroke prevention guidelines for childhood cancer survivors (CCS) treated with cranial irradiation for CNS tumors or other childhood cancers involving the CNS. We used a systematic consensus-building methodology to develop expert recommendations and define areas of controversy in managing asymptomatic CCS at risk for stroke. METHODS: A Delphi process was used to query a multispecialty panel of 45 physicians from the United States/Canada, with expertise in CCS, about their stroke screening and management practices (imaging, referrals, laboratory testing, and medications). Three iterative rounds of anonymous, scenario-based questionnaires, building on panelists' aggregate responses, were used to reach consensus (≥90% agreement), agreement (89%-70% agree), or to understand the rationale for disagreement (<70% agree). RESULTS: All 45 physicians participated in the first 2 rounds and 44 in the third. Panelists reached consensus on indications for referral to neurology and laboratory screening for modifiable cerebral vascular disease (CVD) risk factors in most scenarios. Panelists agreed that aspirin therapy is not recommended in the scenario of normal neuroimaging (86% agreed). Decisions about aspirin therapy in scenarios with abnormal neuroimaging were deferred to specialists; almost all agreed with not using aspirin for cavernomas with no evidence for previous hemorrhage (93%) and using aspirin for both large vessel CVD (93%) and small vessel CVD with evidence of previous stroke (86%). Clinical decisions that remain controversial (less than 70% agreement) include neuroimaging to screen asymptomatic CCS for CVD, referral to neurology for cavernomas, aspirin use in the setting of cavernomas with previous hemorrhage, or with evidence for small vessel CVD and no previous stroke, and indications for statins. Overall, pediatric neurologists/neuro-oncologists and radiation oncologists were more likely to advocate for screening and interventions. DISCUSSION: Despite lack of evidence to guide the management of CCS at risk for stroke, expert recommendations and rationale developed by consensus methodology are helpful to support clinical decision-making.

Randomized Waitlist-Control Trial of a Web-Based Stress-Management and Resiliency Program for Adolescent and Young Adult Cancer Survivors: Protocol for the Bounce Back Study.

BACKGROUND: The emotional health of adolescent and young adult (AYA) cancer survivors is compromised both during and after cancer treatment. Targeted programs designed to support AYAs' ability to cope with stress in the years following treatment completion are lacking. Mind-body programs may ameliorate the negative psychological and emotional effects of stress and assist AYAs with managing the psychosocial challenges of early survivorship. OBJECTIVE: Our randomized waitlist-control trial aims to assess the feasibility, acceptability, and preliminary efficacy of a virtual group program (Bounce Back) to promote stress management and resiliency among posttreatment AYAs. METHODS: Bounce Back is a stress management and resiliency program delivered via videoconference by a trained mental health clinician. Sessions were adapted from an evidence-based mind-body program (Stress Management and Resiliency Training - Relaxation Response Resiliency Program [SMART-3RP]) grounded in relaxation response elicitation, mindfulness, cognitive behavioral therapy, and positive psychology. Seventy-two AYAs (diagnosed with cancer between ages 14 years and 29 years and had completed cancer treatment within the last 5 years) were randomly assigned to the Bounce Back program or waitlist-control group and completed assessments at baseline, 3 months postbaseline, and 6 months postbaseline. The primary aim of the study is to determine the feasibility and acceptability of the Bounce Back program. Descriptive statistics, including means, frequencies, and ranges supplemented by qualitative exit interview feedback will be used to characterize the sample and to summarize feasibility and acceptability. The exploratory aims are to evaluate the preliminary effects of the program on stress coping and psychosocial outcome measures (ie, anxiety, depression) collected across the 3 time points. RESULTS: This study was funded by the National Cancer Institute in July 2017. Study procedures were approved by the Dana-Farber Harvard Cancer Center Institutional Review Board in October 2018 (Protocol 18-428). The randomized trial was conducted from July 2019 to March 2021. Quantitative data collection is complete, and qualitative exit interview data collection is ongoing. Results are expected to be published in peer-reviewed journals and presented at local, national, or international meetings in the coming years. CONCLUSIONS: Few evidence-based programs exist that tackle the key transitional issues faced by AYA cancer survivors. Future analyses will help us determine the feasibility and acceptability of the Bounce Back program and its impact on AYA stress coping and psychological well-being.

Early parental knowledge of late effect risks in children with cancer.

BACKGROUND/OBJECTIVES: Despite the pervasiveness of late effects in childhood cancer survivors, many parents feel inadequately informed about their child's risks. We assessed early parental knowledge of risks of late effects and predictors of increased knowledge. DESIGN/METHODS: Parents of children receiving cancer treatment at Dana-Farber/Boston Children's Cancer and Blood Disorders Center were surveyed about their knowledge of their child's likelihood of eight late effects. Individual risk for each late effect (yes/no) was assessed using the Children's Oncology Group's Long-Term Follow-Up Guidelines v5 as a reference. Descriptive statistics were used to summarize knowledge scores; ordinal logistic regression was used to identify predictors of higher knowledge. RESULTS: Of 96 parent participants, 11 (11.46%) correctly identified all of their child's risks for the eight late effects. Five of eight was the median number of correctly identified late effect risks. Among 21 parents whose children were at risk for ototoxicity, 95% correctly identified this risk. Conversely, parents of at-risk children were less knowledgeable about risks of secondary malignancy (63% correct identification, of N = 94 at risk), cardiac toxicity (61%; N = 71), neurocognitive impairment (56%; N = 63), and infertility (28%; N = 61). Ordinal logistic regression analysis identified no significant differences in parental knowledge of late effect risks by any factors evaluated. CONCLUSIONS: Gaps in parental knowledge of potential late effects of childhood cancer treatment emerge early in a child's care, and parents are more knowledgeable about some late effects, such as ototoxicity, than others, such as infertility. As no child- or parent-specific factors were associated with increased knowledge of late effect risks, interventions must be applied broadly.

Biliary Complications Following Adult Deceased Donor Liver Transplantation: Risk Factors and Implications at a High-volume US Center.

Biliary leaks and anastomotic strictures comprise the majority of biliary complications (BCs) following liver transplantation (LT). Currently, there are few large contemporary case series of BCs in adult deceased donor liver transplant (DDLT) recipients in the literature. The purpose of this study was to examine the pretransplant and intraoperative risk factors associated with BCs at a high-volume tertiary care center and determine the impact of these BCs on their posttransplant course and long-term transplant outcomes. METHODS: We retrospectively reviewed all adult patients undergoing a DDLT from a donor after brain death (DBD) at Emory University between January 2015 and December 2019. RESULTS: A total of 647 adult patients underwent DDLT from a DBD during the study period and were included in analyses. The median length of follow-up posttransplant was 2.5 y. There were a total of 27 bile leaks (4.2%) and 69 biliary strictures (10.7%). Recipient age and cold ischemic time were identified as risk factors for biliary leak, whereas alcoholic cirrhosis as transplant indication was a risk factor for biliary stricture. Placement of a biliary stent was associated with the development of both biliary leaks and anastomotic strictures. Posttransplant, biliary leaks were a significant risk factor for future episodes of acute rejection but did not impact overall survival. In contrast, biliary strictures were associated with a significantly reduced overall survival at 1- and 4-y post DDLT. CONCLUSIONS: BCs are a major source of morbidity and mortality following DDLT, with strictures and leaks associated with distinct posttransplant complications.

Fertility preservation for female patients with childhood, adolescent, and young adult cancer: recommendations from the PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Female patients with childhood, adolescent, and young adult cancer are at increased risk for fertility impairment when treatment adversely affects the function of reproductive organs. Patients and their families desire biological children but substantial variations in clinical practice guidelines reduce consistent and timely implementation of effective interventions for fertility preservation across institutions. As part of the PanCareLIFE Consortium, and in collaboration with the International Late Effects of Childhood Cancer Guideline Harmonization Group, we reviewed the current literature and developed a clinical practice guideline for fertility preservation in female patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger, including guidance on risk assessment and available methods for fertility preservation. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the available evidence and to form the recommendations. This clinical practice guideline leverages existing evidence and international expertise to develop transparent recommendations that are easy to use to facilitate the care of female patients with childhood, adolescent, and young adult cancer who are at high risk for fertility impairment. A complete review of the existing evidence, including a quality assessment, transparent reporting of the guideline panel's decisions, and achievement of global interdisciplinary consensus, is an important result of this intensive collaboration.

Fertility preservation for male patients with childhood, adolescent, and young adult cancer: recommendations from the PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Male patients with childhood, adolescent, and young adult cancer are at an increased risk for infertility if their treatment adversely affects reproductive organ function. Future fertility is a primary concern of patients and their families. Variations in clinical practice are barriers to the timely implementation of interventions that preserve fertility. As part of the PanCareLIFE Consortium, in collaboration with the International Late Effects of Childhood Cancer Guideline Harmonization Group, we reviewed the current literature and developed a clinical practice guideline for fertility preservation in male patients who are diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger, including guidance on risk assessment and available methods for fertility preservation. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the available evidence and to form the recommendations. Recognising the need for global consensus, this clinical practice guideline used existing evidence and international expertise to rigorously develop transparent recommendations that are easy to use to facilitate the care of male patients with childhood, adolescent, and young adult cancer who are at high risk of fertility impairment and to enhance their quality of life.

Communication and ethical considerations for fertility preservation for patients with childhood, adolescent, and young adult cancer: recommendations from the PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group.

Patients with childhood, adolescent, and young adult cancer who will be treated with gonadotoxic therapies are at increased risk for infertility. Many patients and their families desire biological children but effective communication about treatment-related infertility risk and procedures for fertility preservation does not always happen. The PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group reviewed the literature and developed a clinical practice guideline that provides recommendations for ongoing communication methods for fertility preservation for patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger and their families. Moreover, the guideline panel formulated considerations of the ethical implications that are associated with these procedures. Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the evidence and recommendations. In this clinical practice guideline, existing evidence and international expertise are combined to develop transparent recommendations that are easy to use to facilitate ongoing communication between health-care providers and patients with childhood, adolescent, and young adult cancer who might be at high risk for fertility impairment and their families.

Virtual visits as long-term follow-up care for childhood cancer survivors: Patient and provider satisfaction during the COVID-19 pandemic.

Telemedicine can potentially meet objectives of long-term follow-up care (LTFU) for childhood cancer survivors (CCS) while reducing barriers. We surveyed providers at our institution about their satisfaction with video-conference virtual visits (VV) with 81 CCS during COVID-19 restrictions. The same 81 CCS (or parent proxies) were surveyed about their experience, of which 47% responded. Providers and CCS were highly satisfied with VV (86% and 95% "completely/very satisfied," respectively). CCS rated VV "as/nearly as" helpful as in-person visits (66%) and 82% prefer VV remain an option postpandemic. High levels of survivor and provider satisfaction with VV support ongoing investigation into implementation for LTFU.

Long-Term Psychosocial Well-Being and Quality of Life Among Childhood Cancer Survivors Who Developed a Subsequent Malignant Neoplasm.

Childhood cancer survivors (CCS) are at increased risk of subsequent malignant neoplasms (SMNs). However, the impact of SMNs on long-term psychosocial functioning is unknown. In a cohort of 322 young adult CCS, survivors who developed a SMN (n = 43, 13.4%) did not report a significantly higher burden of fatigue, insomnia, depression, anxiety, or impaired quality of life on average 8 years after SMN diagnosis. They, however, endorsed significantly greater body image concerns. Our findings indicate that CCS with an SMN do not significantly differ from those without regarding most psychosocial outcomes in young adulthood, although clinicians may be vigilant for greater body image dissatisfaction.

Aortic Aneurysm Natural Progression is Not Influenced by Concomitant Malignancy and Chemotherapy.

BACKGROUND: Aortic aneurysms occur concomitantly with malignancy in approximately 1.0-17.0% of patients. There is little published information regarding the effects of subsequent oncological therapies on aortic aneurysm growth. The aim of this study was to determine the effects of chemoradiation therapies on the natural progression of small abdominal aortic aneurysm (AAA), thoracic aortic aneurysm, and thoracoabdominal aortic aneurysm. METHODS: Patients with aortic aneurysms with and without malignancy between 2005 and 2017 were identified within institutional databases using Current Procedural Terminology and International Classification of Disease codes. Inclusion criteria included complete chemotherapy documentation, a minimum of 3 multiplanar axial/coronal imaging or ultrasonography before, during, and after receiving therapy or 2 studies for patients without malignancy. Propensity matching, Cox and linear regression, and Kaplan-Meier survival analyses were performed. RESULTS: A total of 159 (172 aneurysms) patients with malignancy and 127 (149 aneurysms) patients without malignancy were included. Average patient demographics were 74.4 ± 9.8-years-old, Caucasian (66.8%), male (70.3%), with hypertension (71.1%), current smoking (24.5%), coronary atherosclerotic disease (26.2%), and AAA (71.0%). The most common malignancy was lung cancer (48.4%) with most chemotherapy regimens including a platinum-based alkylating agent and concurrent antimetabolite (56.0%). The overall median follow-up time was 28.2 (range 3.1-174.4) months. Aortic aneurysms in patients without malignancy grew to larger sizes (4.43 ± 0.96 vs. 4.14 ± 1.00, P = 0.008) with similar median growth rates (0.12 vs. 0.12 cm/year, P = 0.090), had more atypical morphologic features (14.1% vs. 0.6%, P < 0.001), more frequently underwent repair (22.1% vs. 8.7%, P = 0.001), and more frequently required emergency repair for rupture (5.4% vs. 0.0%, P = 0.087). Cox regression identified initial aortic size ≥4.0 cm (hazard ratio [HR] 3.028), AAA (HR 2.146), chronic aortic findings (3.589), and the use of topoisomerase inhibitors (HR 2.694). Linear regression demonstrated increased growth rates predicted by antimetabolite chemotherapy (ß 0.170), initial aortic size (ß 0.086), and abdominal aortic location (ß 0.139, all P < 0.002). CONCLUSIONS: Small aortic aneurysms with concomitant malignancies are discovered at smaller initial sizes, grow at similar rates, require fewer interventions, and have fewer ruptures and acute dissections than patients without malignancy. Antimetabolite therapies modestly accelerate aneurysmal growth, and patients receiving topoisomerase inhibitors may require earlier repair. Patients with concomitant disease can be confidently treated according to standard institutional aneurysm surveillance protocols. Overall, we recommend treatment of the malignancy before small aortic aneurysm repair as these aneurysms behave similarly to those in patients without malignancy.

Outcomes and implications of a single brain death examination policy on organ donation outcomes at a high-volume trauma center.

BACKGROUND: Despite current neurological guidelines that a single brain death examination (SBDE) is sufficient to determine brain death, a vast majority of hospitals still use a two brain death examination (TBDE) policy based on historical practice. The purpose of this study was to analyze the outcomes and implications of an SBDE policy compared with a TBDE policy with respect to organ donation outcomes. METHODS: We retrospectively reviewed all adult patients declared dead by neurological criteria between 2010 and 2018 at a high-volume trauma center. The study population was divided into SBDE and TBDE cohorts. Primary outcomes included time to organ donation, terminal donor creatinine and bilirubin, and number of procured and transplanted organs. RESULTS: A total of 327 patients comprised the study population: 66.7% SBDE (n = 218 of 327 patients) and 33.3% TBDE (n = 109 of 327 patients). The SBDE group had a shorter median time from examination to procurement (38 vs. 44 hours, p = 0.02) as well as lower terminal donor creatinine (1.1 vs. 1.35 mg/dL, p = 0.004) and bilirubin (0.8 vs. 1.1 mg/dL, p = 0.04). Furthermore, the SBDE group had a significantly greater proportion of kidneys (90.6% vs. 81.6%, p = 0.02), lungs (11.8% vs. 4.6%, p = 0.02), and total organs (58.2% vs. 46.6%; p = 0.0001) procured with intent to transplant and a greater proportion of total organs transplanted (53.1% vs. 42.4%, p = 0.0004). Multivariable regression analysis confirmed that SBDE was independently associated with a shorter time to procurement, lower terminal creatinine, and increased number of procured organs. CONCLUSION: These data highlight the potential benefit of an SBDE policy with regards to organ donation outcomes at a high-volume trauma center and should facilitate future randomized prospective studies to more rigorously test this hypothesis.
