RESUMO

BACKGROUND: A challenge facing many Academic Health Centers (AHCs) attempting to revise health professions education to include the impact of racism as a social and structural determinant of health (SSDoH) is a lack of broad faculty expertise to reinforce and avoid undermining learning modules addressing this topic. To encourage an institutional culture that is in line with new anti-racism instruction, we developed a six-part educational series on the history of racism in America and its impact on contemporary health inequities for teaching structural competency to health professions academicians. METHODS: We developed a six-hour elective continuing education (CE) series for faculty and staff with the following objectives: (1) describe and discuss race as a social construct; (2) describe and discuss the decolonization of the health sciences and health care; (3) describe and discuss the history of systemic racism and structural violence from a socio-ecological perspective; and (4) describe and discuss reconciliation and repair in biomedicine. The series was spread over a six-month period and each monthly lecture was followed one week later by an open discussion debriefing session. Attendees were assessed on their understanding of each objective before and after each series segment. RESULTS: We found significant increases in knowledge and understanding of each objective as the series progressed. Attendees reported that the series helped them grapple with their discomfort in a constructive manner. Self-selected attendees were overwhelmingly women (81.8%), indicating a greater willingness to engage with this material than men. CONCLUSIONS: The series provides a model for AHCs looking to promote anti-racism and structural competency among their faculty and staff.

RESUMO

Future far-infrared astrophysics observatories will require focal plane arrays containing thousands of ultrasensitive, superconducting detectors, each of which require efficient optical coupling to the telescope fore-optics. At longer wavelengths, many approaches have been developed, including feedhorn arrays and macroscopic arrays of lenslets. However, with wavelengths as short as 25 µm, optical coupling in the far infrared remains challenging. In this paper, we present an approach to fabricate far-infrared monolithic silicon microlens arrays using grayscale lithography and deep reactive ion etching. The fabricated microlens arrays presented here are designed for two different wavebands: 25-40 µm and 135-240 µm. The microlens arrays have sags as deep as 150 µm, are hexagonally packed with a pixel pitch of 900 µm, and have an overall size as large as 80 by 15 mm. We compare an as-fabricated lens profile to the design profile and calculate that the fabricated lenses would achieve 84% encircled power for the designed detector, which is only 3% less than the designed performance. We also present methods developed for antireflection coating microlens arrays and for a silicon-to-silicon die bonding process to hybridize microlens arrays with detector arrays.

RESUMO

OBJECTIVE: To quantify racial disparities in mortality and post-hospitalization outcomes among incarcerated individuals that were hospitalized during their incarceration period. METHODS: We designed a retrospective cohort study using administrative and hospital data collected from a preferred healthcare referral center for all Massachusetts jails and prisons between January 2011 and December 2018 with linkage to Massachusetts Vital Records and Statistics. We identified 4260 incarcerated individuals with complete data on race/ethnicity that were hospitalized during the study period. The primary study indicators were age, race, ethnicity, length of hospital stay, Elixhauser comorbidity score, incarceration facility type, and number of hospital admissions. The primary outcome was time to death. RESULTS: Of the incarcerated individuals that were hospitalized, 2606 identified as White, 1214 identified as Black, and 411 people who identified as some other race. The hazard of death significantly increased by 3% (OR: 1.03; 95% CI: 1.02-1.03) for each additional yearly increase in age. After adjusting for the interaction between race and age, Black race was significantly associated with 3.01 increased hazard (95% CI: 1.75-5.19) of death for individuals hospitalized while incarcerated compared to White individuals hospitalized while incarcerated. Hispanic ethnicity and being incarcerated in a prison facility was not associated with time to mortality, while increased mean Elixhauser score (HR: 1.07; 95% CI: 1.06-1.08) and ≥ 3 hospital admissions (HR: 2.47; 95% CI: 2.07-2.95) increased the hazard of death. CONCLUSIONS: Our findings suggest disparities exist in the mortality outcomes among Black and White individuals who are hospitalized during incarceration, with an increased rate of death among Black individuals. Despite hypothesized equal access to healthcare within correctional facilities, our findings suggest that incarcerated and hospitalized Black individuals may experience worse disparities than their White counterparts, which has not been previously explored or reported in the literature. In addition to decarceration, advocacy, and political efforts, increased efforts to support research access to datasets of healthcare outcomes, including hospitalization and death, for incarcerated people should be encouraged. Further research is needed to identify and address the implicit and explicit sources of these racial health disparities across the spectrum of healthcare provision.

RESUMO

OBJECTIVES: This study aimed to discover how the COVID-19 pandemic altered the implementation of the social model of recovery in sober living homes (SLHs). Researchers analyzed associations between residents' feelings of interconnectedness, social service utilization, and relapse predictors throughout the pandemic. This study provides an understanding of how the COVID-19 pandemic impacted treatment of substance use disorder (SUD). METHODS: This study used retrospective surveyed data from 105 SLH residents. Correlational analysis was used to determine the relationship between social service use, social connectivity, and relapse predictors at three different time points: February 2020, December 2020, and June 2021. Three residents underwent additional interviews. RESULTS: There was a decline in social service utilization from February 2020 to December 2020 with an associated decline in feelings of social connectivity. From December 2020 to June 2021, there was an increase in residents' use of social services with an associated increase in connectivity. There was a significant negative correlation between relapse predictors and number of supportive services used in February 2020 ( r = -0.217, P < 0.05) and in December 2020 ( r = -0.352, P < 0.001). In June 2020, there was a significant negative correlation between interconnectedness and relapse predictors ( r = -0.297, P < 0.05). The number of interviews was not sufficient for formal qualitative analysis. CONCLUSIONS: The results suggest the COVID-19 pandemic possibly interrupted the course of recovery in SLHs. These findings offer insight to how the pandemic impacted individuals recovering from SUD and suggest that SUD treatment professionals should develop interventions to enhance social connectivity to deploy in response to global stressors.

RESUMO

Clinical trials conducted with incarcerated populations are rare. We present a case example of one such jail-based cancer prevention clinical trial to demonstrate the importance of including a theory-driven approach to intervention framing, novel experimental designs to boost access to low-risk trials, and retention strategies for long-term follow-up of hard-to-reach populations. As such we offer a social determinant of health framework to ensure cancer prevention research is conducted through the lenses of health promotion and health equity. Deviations from the gold-standard randomized control design, transparent systematic allotment, and street-based outreach retention strategies contribute to the feasibility of conducting clinical trials in carceral settings and after people leave jail. Best practices presented can be used in design and conduct of future clinical trials with criminal legal system-involved populations.

RESUMO

People with lived experience of incarceration have higher rates of morbidity and mortality compared to people without history of incarceration. Research conducted unethically in prisons and jails led to increased scrutiny of research to ensure the needs of those studied are protected. One consequence of increased restrictions on research with criminal-legal involved populations is reluctance to engage in research evaluations of healthcare for people who are incarcerated and people who have lived experience of incarceration. Ethical research can be done in partnership with people with lived experience of incarceration and other key stakeholders and should be encouraged. In this article, we describe how stakeholder engagement can be accomplished in this setting, and further, how such engagement leads to impactful research that can be disseminated and implemented across disciplines and communities. The goal is to build trust across the spectrum of people who work, live in, or are impacted by the criminal-legal system, with the purpose of moving toward health equity.

RESUMO

Limited women's health and cancer prevention materials are available that have been validated for vulnerable populations. Such materials are especially important for groups, which have intermittent and typically low-quality healthcare access and are at greatest risk for missing out on women's health and cancer prevention screening. Health education materials are developed from heterogeneous sources. Clinical and research teams have minimal guidance in terms of sources, timelines, outputs, and evaluation in the development of such materials. The goal of this paper is to share our process in developing and evaluating an up-to-date women's health and cancer prevention learning guide appropriate for a target population of women involved in the criminal justice system. A ten-page learning guide was drafted using the current evidence-based data, with the objective of providing educational material on four topics: cervical cancer, breast cancer, sexually transmitted infection, and unintended pregnancy prevention. The learning guide was then tested on a convenience sample of 33 women at a local county jail. Feedback was organized into three parts in which the participants Responded to open-ended question, "What is missing?" Rated each of the four topics for design and content Completed a usability assessment Common themes were participants' interest in learning about side effects of birth control and wanting more information on testing and treatment, specifically for sexually transmitted infections (STIs). Women were satisfied with the cancer prevention information presented to them. This report provides a framework for cancer prevention researchers who are developing health education materials for vulnerable populations.

RESUMO

Extensive health inequities exist for persons with criminal-legal involvement in the USA. Researchers, both novice and experienced, are critical in documenting these inequities and implementing programs that address the many health and social problems of this population. However, working with currently or formerly incarcerated persons brings new challenges to researchers that may have not been previously considered as necessary. Because incarcerated persons were systemically exploited by biomedical researchers until reform following the Civil Rights Movement, resulting in their designation as a vulnerable population in the Code of Federal Regulations, enhanced protections are necessary in implementing contemporary research involving incarcerated persons. These enhanced protections can delay or prolong the regulatory approval process, particularly to the novice carceral system researcher, which may discourage some from engaging with this important population. Drawing on the many years of experience working with incarcerated persons accumulated by the Sexual Health Empowerment (S)HE Team at the University of Kansas Medical Center (KUMC), this article offers some concrete steps toward getting started in this work.

RESUMO

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare but aggressive malignancy, and many prognostic factors that influence survival remain undefined. Individually, the GRAS (Grade, Resection status, Age, and Symptoms of hormone hypersecretion) parameters have demonstrated their prognostic value in ACC. This study aimed to assess the value of a cumulative GRAS score as a prognostic indicator after ACC resection. METHODS: A retrospective cohort study of adult patients who underwent surgical resection for ACC between 1993 and 2014 was performed using the United States Adrenocortical Carcinoma Group (US-ACCG) database. A sum GRAS score was calculated for each patient by adding one point each when the criteria were met for tumor grade (Weiss criteria ≥ 3 or Ki67 ≥ 20%), resection status (micro- or macroscopically positive margin), age (≥ 50 years), and preoperative symptoms of hormone hypersecretion (present). Overall survival (OS) and disease-free survival (DFS) by cumulative GRAS score were analyzed by the Kaplan-Meier method and log-rank test. RESULTS: Of the 265 patients in the US-ACCG database, 243 (92%) had sufficient data available to calculate a cumulative GRAS score and were included in this analysis. The 265 patients comprised 23 patients (10%) with a GRAS of 0, 52 patients (21%) with a GRAS of 1, 92 patients (38%) with a GRAS of 2, 63 patients (26%) with a GRAS of 3, and 13 patients (5%) with a GRAS of 4. An increasing GRAS score was associated with shortened OS (p < 0.01) and DFS (p < 0.01) after index resection. CONCLUSION: In this retrospective analysis, the cumulative GRAS score effectively stratified OS and DFS after index resection for ACC. Further prospective analysis is required to validate the cumulative GRAS score as a prognostic indicator for clinical use.

RESUMO

Correctional systems in several U.S. states have entered into partnerships with academic medical centers (AMCs) to provide healthcare for persons who are incarcerated. One AMC specializing in the care of incarcerated patients is the University of Texas Medical Branch at Galveston (UTMB), which hosts the only dedicated prison hospital in the U.S. and supplies 80% of the medical care for the entire Texas Department of Criminal Justice (TDCJ). Nearly all medical students and residents at UTMB take part in the care of the incarcerated. This research, through qualitative exploration using focus group discussions, sets out to characterize the correctional care learning environment medical trainees enter. Participants outlined an institutional culture of low prioritization and neglect that dominated the learning environment in the prison hospital, resulting in treatment of the incarcerated as second-class patients. Medical learners pointed to delays in care, both within the prison hospital and within the TDCJ system, where diagnostic, laboratory, and medical procedures were delivered to incarcerated patients at a lower priority compared to free-world patients. Medical learners elaborated further on ethical issues that included the moral judgment of those who are incarcerated, bias in clinical decision making, and concerns for patient autonomy. Medical learners were left to grapple with complex challenges like the problem of dual loyalties without opportunities to critically reflect upon what they experienced. This study finds that, without specific vulnerable populations training for both trainees and correctional care faculty to address these institutional dynamics, AMCs risk replicating a system of exploitation and neglect of incarcerated patients and thereby exacerbating health inequities.

RESUMO

BACKGROUND: Correctional systems in several U.S. states have entered into partnerships with Academic Medical Centers (AMCs) to provide healthcare for people who are incarcerated. This project was initiated to better understand medical trainee perspectives on training and providing healthcare services to prison populations at one AMC specializing in the care of incarcerated patients: The University of Texas Medical Branch at Galveston (UTMB). We set out to characterize the attitudes and perceptions of medical trainees from the start of their training until the final year of Internal Medicine residency. Our goal was to analyze medical trainee perspectives on caring for incarcerated patients and to determine what specialized education and training is needed, if any, for the provision of ethical and appropriate healthcare to incarcerated patients. RESULTS: We found that medical trainees grapple with being beneficiaries of a state and institutional power structure that exploits the neglected health of incarcerated patients for the benefit of medical education and research. The benefits include the training opportunities afforded by the advanced pathologies suffered by persons who are incarcerated, an institutional culture that generally allowed students more freedom to practice their skills on incarcerated patients as compared to free-world patients, and an easy compliance of incarcerated patients likely conditioned by their neglect. Most trainees failed to recognize the extreme power differential between provider and patient that facilitates such freedom. CONCLUSIONS: Using a critical prison studies/Foucauldian theoretical framework, we identified how the provision/withholding of healthcare to and from persons who are incarcerated plays a major role in disciplining incarcerated bodies into becoming compliant medical patients and research subjects, complacent with and even grateful for delayed care, delivered sometimes below the standard best practices. Specialized vulnerable-population training is sorely needed for both medical trainees and attending physicians in order to not further contribute to this exploitation of incarcerated patients.

RESUMO

BACKGROUND: Adrenocortical carcinoma is a rare, aggressive cancer. We compared features of patients who underwent synchronous versus metachronous metastasectomy. METHODS: Adult patients who underwent resection for metastatic adrenocortical carcinoma from 1993 to 2014 at 13 institutions of the US adrenocortical carcinoma group were analyzed retrospectively. Patients were categorized as synchronous if they underwent metastasectomy at the index adrenalectomy or metachronous if they underwent resection after recurrence of the disease. Factors associated with overall survival were assessed by univariate analysis. RESULTS: In the study, 84 patients with adrenocortical carcinoma underwent metastasectomy; 26 (31%) were synchronous and 58 (69%) were metachronous. Demographics were similar between groups. The synchronous group had more T4 tumors at the index resection (42 vs 3%, P < .001). The metachronous group had prolonged median survival after the index resection (86.3 vs 17.3 months, P < .001) and metastasectomy (36.9 vs 17.3 months, P = .007). Synchronous patients with R0 resections had improved survival compared to patients with R1/2 resections (P = .008). Margin status at metachronous metastasectomy was not associated with survival (P = .452). CONCLUSION: Select patients with metastatic adrenocortical carcinoma may benefit from metastasectomy. Patients with metachronous metastasectomy have a more durable survival benefit than those undergoing synchronous metastasectomy. This study highlights need for future studies examining differences in tumor biology that could explain outcome disparities in these distinct patient populations.

RESUMO

BACKGROUND: Patterns and prognostic implications of recurrent adrenocortical carcinoma are poorly understood. In this study, we aim to describe temporal and spatial patterns of adrenocortical carcinoma recurrence. METHODS: This is a retrospective review of 576 patients with adrenocortical carcinoma evaluated at a single institution. Clinicopathologic and follow-up data were collected longitudinally. RESULTS: A total of 354 patients underwent resection of stage I-III adrenocortical carcinoma. We found that 249 (70%) patients developed disease recurrence. The median recurrence-free interval after primary resection was 11 months. The most common sites of initial recurrence were lung and tumor bed. The shortest time to recurrence was associated with lung or multiple site metastases. We found that 142 of 249 patients developed one or more additional sites of recurrence (median 5 months), most commonly involving the lungs. A total of 20 patients developed a third site of recurrence. We found that 100 patients underwent one or more reoperations or metastasectomies and 79 recurred again after reoperation. Same organ or site recurrence was common after reoperation (67%). Although lung metastases occurred early, recurrences to the peritoneal cavity or to multiple sites were associated with worse survival. Metastasectomy beyond three total operations did not improve overall survival. CONCLUSION: Survival varies according to site of recurrence and other clinicopathologic factors. Knowledge of patterns of recurrence may assist in anticipating disease course and lead to better informed selection of treatment.

RESUMO

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare and aggressive cancer. This report describes factors and outcomes associated with resection of extra-adrenal organs en bloc during index adrenalectomy. METHODS: Patients who underwent ACC resection for non-metastatic disease from 1993 to 2014 at 13 participating institutions of the US-ACC Group were included in the study. Factors associated with en bloc resection were assessed by uni- and multivariate analysis. The primary end point was overall survival. RESULTS: In this study, 167 patients were included and categorized as adrenalectomy with en bloc resection (AdEBR) if they had extra-adrenal organs removed or adrenalectomy (Ad) if they did not. The demographics were similar between the AdEBR (n = 68, 40.7%) and Ad groups, including age, gender, race, American Society of Anesthesiology (ASA) class, and body mass index (BMI). The AdEBR group had larger tumors (13 vs. 10 cm), more open operations (97.1 vs. 63.6%), and more lymph node dissections (LNDs) (36.8 vs. 12.1%). The most common organs removed were kidney (55.9%), liver (27.9%), and spleen (23.5%). Multiple organs were removed in 38.2% (n = 26) of the patients. Margin-negative resections were similar between the two groups. In the multivariate Cox regression adjusted for T and N stages, LND, margin, size, and hormone hypersecretion, en bloc resection was not associated with improved survival (hazard ratio [HR], 1.42; p = 0.323). CONCLUSION: The study findings validated current practice by showing that en bloc resection should occur at index adrenalectomy for ACC when a T4 lesion is suspected pre- or intraoperatively, or when it is necessary to avoid tumor rupture. However, in this study, when a negative margin resection was otherwise achieved, removal of extra-adrenal organs en bloc was not associated with additional survival benefit.

RESUMO

BACKGROUND: The 7th AJCC T-stage system for adrenocortical carcinoma (ACC), based on size and extra-adrenal invasion, does not adequately stratify patients by survival. Lymphovascular invasion (LVI) is a known poor prognostic factor. We propose a novel T-stage system that incorporates LVI to better risk-stratify patients undergoing resection for ACC. METHOD: Patients undergoing curative-intent resections for ACC from 1993 to 2014 at 13 institutions comprising the US ACC Group were included. Primary outcome was disease-specific survival (DSS). RESULTS: Of the 265 patients with ACC, 149 were included for analysis. The current T-stage system failed to differentiate patients with T2 versus T3 disease (p = 0.10). Presence of LVI was associated with worse DSS versus no LVI (36 mo vs. 168 mo; p = 0.001). After accounting for the individual components of the current T-stage system (size, extra-adrenal invasion), LVI remained a poor prognostic factor on multivariable analysis (hazard ratio 2.14, 95% confidence interval 1.05-4.38, p = 0.04). LVI positivity further stratified patients with T2 and T3 disease (T2: 37 mo vs. median not reached; T3: 36 mo vs. 96 mo; p = 0.03) but did not influence survival in patients with T1 or T4 disease. By incorporating LVI, a new T-stage classification system was created: [T1: ≤ 5 cm, (-)local invasion, (+/-)LVI; T2: > 5 cm, (-)local invasion, (-)LVI OR any size, (+)local invasion, (-)LVI; T3: > 5 cm, (-)local invasion, (+)LVI OR any size, (+)local invasion, (+)LVI; T4: any size, (+)adjacent organ invasion, (+/-)LVI]. Each progressive new T-stage group was associated with worse median DSS (T1: 167 mo; T2: 96 mo; T3: 37 mo; T4: 15 mo; p < 0.001). CONCLUSIONS: Compared with the current T-stage system, the proposed T-stage system, which incorporates LVI, better differentiates T2 and T3 disease and accurately stratifies patients by disease-specific survival. If externally validated, this T-stage classification should be considered for future AJCC staging systems.

RESUMO

Perioperative blood transfusion is associated with decreased survival in pancreatic, gastric, and liver cancer. The effect of transfusion in adrenocortical carcinoma (ACC) has not been studied. Patients with available transfusion data undergoing curative-intent resection of ACC from 1993 to 2014 at 13 institutions comprising the United States Adrenocortical Carcinoma Group were included. Factors associated with blood transfusion were determined. Primary and secondary end points were recurrence-free survival (RFS) and overall survival (OS), respectively. Out of 265 patients, 149 were included for analysis. Out of these, 57 patients (38.3%) received perioperative transfusions. Compared to nontransfused patients, transfused patients more commonly had stage 4 disease (46% vs 24%, P = 0.01), larger tumors (15.8 vs 10.2 cm, P < 0.001), inferior vena cava involvement (24.6% vs 5.4%, P = 0.002), additional organ resection (78.9% vs 36.3%, P < 0.001), and major complications (29% vs 2%, P < 0.001). Transfusion was associated with decreased RFS (8.9 vs 24.7 months, P = 0.006) and OS (22.8 vs 91.0 months, P < 0.001). On univariate Cox regression, transfusion, stage IV, hormonal hypersecretion, and adjuvant therapy were associated with decreased RFS. On multivariable analysis, only transfusion [hazard ratio (HR) = 1.7, 95% confidence interval (CI) =1.0-2.9, P = 0.04], stage IV (HR = 3.2, 95% CI = 1.7-5.9, P < 0.001), and hormonal hypersecretion (HR = 2.6, 95% CI = 1.5-4.2, P < 0.001) were associated with worse RFS. When applying this model to OS, similar associations were seen (transfusion HR = 2.0, 95% CI = 1.1-3.8, P = 0.02; stage 4 HR = 6.2, 95% CI = 3.1-12.4, P < 0.001; hormonal hypersecretion HR = 3.5, 95% CI = 1.9-6.4, P < 0.001). There was no difference in outcomes between patients who received 1 to 2 units versus >2 units of packed red blood cells in median RFS (8.9 vs 8.4 months, P = 0.95) or OS (26.5 vs 18.6 months, P = 0.63). Perioperative transfusion is associated with earlier recurrence and decreased survival after curative-intent resection of ACC. Strategies and protocols to minimize blood transfusion should be developed and followed.

OBJECTIVE: To evaluate conditional disease-free survival (CDFS) for patients who underwent curative intent surgery for adrenocortical carcinoma (ACC). BACKGROUND: ACC is a rare but aggressive tumor. Survival estimates are usually reported as survival from the time of surgery. CDFS estimates may be more clinically relevant by accounting for the changing likelihood of disease-free survival (DFS) according to time elapsed after surgery. METHODS: CDFS was assessed using a multi-institutional cohort of patients. Cox proportional hazards models were used to evaluate factors associated with DFS. Three-year CDFS (CDFS3) estimates at "x" year after surgery were calculated as follows: CDFS3 = DFS(x+3)/DFS(x). RESULTS: One hundred ninety-two patients were included in the study cohort; median patient age was 52 years. On presentation, 36% of patients had a functional tumor and median size was 11.5 cm. Most patients underwent R0 resection (75%) and 9% had N1 disease. Overall 1-, 3-, and 5-year DFS was 59%, 34%, and 22%, respectively. Using CDFS estimates, the probability of remaining disease free for an additional 3 years given that the patient had survived without disease at 1, 3, and 5 years, was 43%, 53%, and 70%, respectively. Patients with less favorable prognosis at baseline demonstrated the greatest increase in CDFS3 over time (eg, capsular invasion: 28%-88%, Δ60% vs no capsular invasion: 51%-87%, Δ36%). CONCLUSIONS: DFS estimates for patients with ACC improved dramatically over time, in particular among patients with initial worse prognoses. CDFS estimates may provide more clinically relevant information about the changing likelihood of DFS over time.

RESUMO

BACKGROUND: Lymph node metastasis is an established predictor of poor outcome for adrenocortical carcinoma (ACC); however, routine lymphadenectomy during surgical resection of ACC is not widely performed and its therapeutic role remains unclear. METHODS: Patients undergoing margin-negative resection for localized ACC were identified from a multi-institutional database. Patients were stratified into 2 groups based on the surgeon's effort or not to perform a lymphadenectomy as documented in the operative note. Clinical, pathologic, and outcome data were compared between the 2 groups. RESULTS: Of 120 patients who met inclusion criteria from 1993 to 2014, 32 (27 %) underwent lymphadenectomy. Factors associated with lymphadenectomy were tumor size (12 vs. 9.5 cm; p = .007), palpable mass at presentation (26 vs. 12 %; p = .07), suspicious lymph nodes on preoperative imaging (44 vs. 7 %; p < .001), and need for multivisceral resection (78 vs. 36 %; p < .001). Median number of lymph nodes harvested was higher in the lymphadenectomy group (5.5 vs. 0; p < .001). In-hospital mortality (0 vs. 1.3 %; p = .72) and grade 3/4 complication rates (0 vs. 12 %; p = .061) were not significantly different. Patients who underwent lymphadenectomy had improved overall survival (5-year 76 vs. 59 %; p = .041). The benefit of lymphadenectomy on overall survival persisted on multivariate analysis (HR = 0.17; p = .006) controlling for adverse preoperative and intraoperative factors associated with lymphadenectomy, such as tumor size, palpable mass, irregular tumor edges, suspicious nodes on imaging, and multivisceral resection. CONCLUSIONS: In this multicenter study of adrenocortical carcinoma patients undergoing R0 resection, the surgeon's effort to dissect peritumoral lymph nodes was independently associated with improved overall survival.

RESUMO

BACKGROUND: Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with limited therapeutic options beyond surgical resection. The characteristics of actual long-term survivors following surgical resection for ACC have not been previously reported. METHOD: Patients who underwent resection for ACC at one of 13 academic institutions participating in the US Adrenocortical Carcinoma Group from 1993 to 2014 were analyzed. Patients were stratified into four groups: early mortality (died within 2 years), late mortality (died within 2-5 years), actual 5-year survivor (survived at least 5 years), and actual 10-year survivor (survived at least 10 years). Patients with less than 5 years of follow-up were excluded. RESULTS: Among the 180 patients available for analysis, there were 49 actual 5-year survivors (27%) and 12 actual 10-year survivors (7%). Patients who experienced early mortality had higher rates of cortisol-secreting tumors, nodal metastasis, synchronous distant metastasis, and R1 or R2 resections (all P < 0.05). The need for multi-visceral resection, perioperative blood transfusion, and adjuvant therapy correlated with early mortality. However, nodal involvement, distant metastasis, and R1 resection did not preclude patients from becoming actual 10-year survivors. Ten of twelve actual 10-year survivors were women, and of the seven 10-year survivors who experienced disease recurrence, five had undergone repeat surgery to resect the recurrence. CONCLUSION: Surgery for ACC can offer a 1 in 4 chance of actual 5-year survival and a 1 in 15 chance of actual 10-year survival. Long-term survival was often achieved with repeat resection for local or distant recurrence, further underscoring the important role of surgery in managing patients with ACC. J. Surg.
