Abstract
We present a case detailing the successful reconstruction of the hindfoot in a 15-year-old male patient who suffered a self-inflicted shotgun wound. The patient had multiple complex fractures in these bones, resulting in considerable bone loss and the destruction of the articular surface. Considering the extent of the injuries and the failure of prior intervention from an outside surgeon, traditional reconstruction methods would not have adequately addressed the severity of the damage. Consequently, the treating physician opted to address the deformity using a three-dimensional (3D)-printed custom implant to salvage the limb. The treatment involved a two-stage surgical plan. The first stage encompassed debridement with the removal of antibiotic cement, which had been placed at the time of the initial injury, followed by debridement and placement of a new temporary antibiotic spacer. A 21-day course of antibiotics was administered to combat the developing osteomyelitis. Following the successful eradication of the infection, a second surgery entailed removing the spacer and residual bone, inserting the 3D-printed implant filled with bone graft, and fusing the hindfoot. Post-surgery, the patient steadily progressed from non-weight-bearing to full weight-bearing and was fully weight-bearing at five months post-surgery. He had reported significant improvements in pain and mobility. There were no complications, and the 3D-printed implant exhibited excellent integration with the surrounding bone tissue with a two-year follow-up. This case serves as a demonstration of the utility of 3D-printed custom implants in severe foot and ankle trauma, showcasing the technology's potential to revolutionize orthopedic surgery. Despite the potential risks, this approach highlights significant benefits and opens avenues for tailored reconstructions in complex orthopedic injuries.

Abstract
BACKGROUND Despite notable progress over time, broad insight into the scientific landscape of orthopaedic oncology is lacking. We conducted a bibliometric analysis of the 500 most cited papers in the field. METHODS We searched the Science Citation Index Expanded database of the Web of Science Core Collection to find the 500 most cited articles in the field. RESULTS Citation count ranged from 81 to 1,808. Articles were published from 1965 to 2018. Over half of all articles were published in the United States (53.6%). The 2000s was the most productive decade with 170 (34%) articles. All articles were written in English and were published across 29 journals. Female participation as first authors significantly increased from the 1960s to the 2010s (0% vs 14.6%, P = 0.0434). Similarly, female involvement as senior authors grew from the 1960s to the 2010s (0% vs 12.2%, P = 0.0607). Primary bone sarcomas were the most cited topic among articles from the 1970s to the 1980s. From studies produced in the 1990s up until the 2010s, reconstruction procedures were the most cited topic. CONCLUSION Trends over the years have resulted in an emphasis on a surgical technique. Notable progress has been made regarding gender diversity, yet disparities still exist.

Abstract
Background Ankle fractures are a frequent injury in the adult population and a quarter of all ankle fractures are classified as unstable, requiring surgical intervention. Plate-and-screw construct is the traditionally used fixation method for fibula fractures. The use of an intramedullary nail is an alternative fixation method, with current literature supporting very low complication rates and hardware removal surgeries. The purpose of this study was to evaluate the outcomes, including complication rates and implant removal rates, using a fibula nail with both proximal and distal fixation capabilities by an experienced surgeon. Methods We retrospectively reviewed 203 consecutive fibula nail cases from a single surgeon using a mini-open technique for anatomic reduction. Demographic, operative, clinical, and radiographic outcome data were analyzed, specifically examining complication rates and need for implant removal. Results The average follow-up was 18.8 months (6-54 months). All fractures healed. We identified 2 cases of superficial wound infection, 1 superficial peroneal nerve irritation, and 1 case of implant removal. In the first 110 cases, 2 fractures were converted to a plate intraoperatively prior to a technique modification which has prevented this occurrence. No deep infection, delayed union, or nonunion occurred. Conclusion Our data support that fibula nails with proximal and distal locking capabilities offer an alternative to plating with the potential for lower complication rates and lower need for implant removal. Level of evidence Level IV, case series.

Abstract
BACKGROUND Foot and ankle soft tissue sarcomas (STSs) are rare neoplasms associated with a high risk of local recurrence and metastasis. Although amputation is often performed, its impact on prognosis remains unknown. The aims of our systematic review were identifying risk factors for (1) disease-specific death, (2) local recurrence, (3) metastasis, and assessing (4) whether the type of surgery (amputation or limb-salvage) affected disease-specific survival. METHODS This systematic review was conducted following PRISMA guidelines. The PubMed, Embase, and Scopus databases were searched. Our study was registered in PROSPERO (ID: 415624). Quality appraisal was done using STROBE guidelines. RESULTS A total of 7 studies and 123 patients were included. Metastasis was the only risk factor for disease-specific death (OR = 107.85, P< .001). Previous unplanned excision (OR = 22.29, P = .009) and positive margins (OR = 64.48, P = .011) were associated with higher risk of local recurrence. Patients with high-grade tumors (OR = 13.22, P = .023) and tumors ≥6 cm (OR = 7.40, P = .022) were more likely to develop metastases. After adjusting for confounders (age, sex, and presence of metastasis), amputation was not associated with poorer disease-specific survival. CONCLUSION Metastasis was the single most important risk factor for death with foot and ankle soft tissue sarcoma. Positive margins and history of previous unplanned excision are risk factors for local recurrence. The most important risk factors for metastasis are tumor grade and size ≥6 cm. Amputation was not associated with poorer disease-specific survival.

Abstract
BACKGROUND Motorcycle road traffic collisions are a major cause of mortality in the United States. We aimed to analyze the temporal and statewide trends in motorcycle collision fatalities (MCFs) nationwide and their association with state laws regarding motorcycle helmet requirements, lane splitting, speeding, intoxicating driving, and red light cameras. METHODS A retrospective review of United States MCF/capita from 2015 to 2019 was performed using the Fatality Analysis Reporting System database. MCF/capita was defined as a motorcyclist death per 100 000 motorcyclist registrations. Independent-samples t-test and ANOVA were used to determine differences, with significance defined as P < .05. Linear regression analysis and Pearson's correlation were used to further determine associations between variables. RESULTS The majority of fatalities occurred in males (n = 21 354, 91.0%), ages 25-54 (n = 13 728, 58.5%), and Caucasians (n = 19 195, 81.8%). A total of 24 states and DC exhibited positive trends in MCF/capita from 2015 to 2019. There was no significant difference in MCF/capita between states who had mandatory helmet laws for all, partial requirements, and states with no law (63.4 vs 54.3 vs 33.6, P = .360). Among fatalities involving alcohol, a significantly greater number of MCF/capita were found above the legal limit of .08 compared to the group with a blood alcohol concentration of .01-.07 (17.8 vs 4.5, P < .001). CONCLUSION Motorcyclist fatalities continue to pose a public health risk, with 24 states showing an upward trend. Additional interventions and laws are needed to decrease the number of motorcyclist deaths. Further strategy on implementation and enforcement of helmet laws and alcohol consumption may be an essential component.

Abstract
Introduction Breast surgical oncology is a defined sub-specialty of general surgery that focuses on the surgical management of breast disease and malignancy within a multidisciplinary context. The fellowship directors (FD) that lead these programs have been selected for their abilities. As programs do research to ensure proper training for the next generation of breast surgical oncologists, we wanted to look into the FDs responsible for their training. Methods The Breast Surgical Oncology care program list was compiled via the Society of Surgical Oncology and American Society of Breast Surgeons Accredited programs (n = 60). The demographic information that was of interest included, but was not limited to, gender, age, ethnicity/background, past residency training, past fellowship training, year graduated from residency and fellowship, year since graduation to FD appointment, time at institution till FD appointment, and Hirsch index (h-index). Results Data were collected on all 60 FDs. The average age of FDs was 52 years old, 27% of FDs are men and 73% of FDs are women. The average H-index, number of publications, and number of citations were 19, 67, and 2648, respectively. The mean graduation year from residency was 2003, and from fellowship was 2006; with a mean of 9 years post fellowship graduation until becoming an FD. The most frequently attended residency was Rush (n = 4), and the most common fellowships were Memorial Sloan Kettering (n = 8), MD Anderson Cancer Center (n = 7), and John Wayne Cancer Institute (n = 4). Nine of the FDs stayed at the same institution after doing both residency and fellowship there (15%). Conclusion This is the first study to examine the demographics of those in FD positions in Surgical Breast Oncology, which is a relatively young fellowship. We found that FDs in Breast Surgical Oncology are defined by their high output of research. This qualification may be why the average age, and the number of years to FD are higher compared to other specialties where this research has been undertaken. Initial evaluation of FDs suggest more diversity in this field is needed. Further insight into the leaders training our next generation of surgeons is warranted.

Abstract
BACKGROUND Emergency department thoracotomy is often performed on patients in extremis from traumatic exsanguination. Thus, inherent biases may play a role in whether or not the emergency department thoracotomy is performed. We aimed to investigate race, socioeconomic status, and gender disparities in the use of emergency department thoracotomy and to investigate outcomes of these patients to assess for possible surgeon practice bias. METHOD A nationwide retrospective cohort analysis of the American College of Surgeons Trauma Quality Programs Participant Use Profile 2016-2018. Adult patients who suffered blunt, penetrating, or other injuries secondary to falls/firearms/motor vehicle collision/other mechanisms of injury and presented to a trauma center pulseless, with or without signs of life after injury. Rates of thoracotomy, time to thoracotomy, transfer to operating room, emergency department disposition, intensive care unit length of stay, hospital length of stay, complications, mortality, and hospital disposition. Univariate analyses and adjusted multivariable regression were performed to account for confounders with significance defined as P < .05. RESULTS A total of 6,453 patients were analyzed. Emergency department thoracotomy and mortality were significantly higher in minorities and uninsured patients, even after risk adjustment. There were no differences in timing among race groups to emergency department thoracotomy. White/Caucasian patients experienced the highest rate of emergency department initial disposition to the intensive care unit (10.3%, P < .0001) and lowest mortality rate (89.2%, P < .0001). CONCLUSION Surgeon bias was not seen in the practice of emergency department thoracotomy for patients arriving pulseless. However, poorer outcomes were associated with minorities and lower socioeconomic status patients. Thoracotomy rates were higher in minorities and lower socioeconomic status patients due to more penetrating trauma.

Abstract
BACKGROUND We aim to identify patient cohorts where laparoscopy can be safely utilized with comparable or better outcomes to laparotomy among patients with single penetrating LUQ injuries with a hypothesis that compared to laparotomy, laparoscopy may be associated with equal or improved outcomes of low injury severity patients. METHODS Retrospective review of the ACS-TQP-Participant Use File 2016-2019 dataset. Patients with single LUQ penetrating injuries were included. Primary outcome was risk-adjusted in-hospital mortality. Secondary outcomes included: risk-adjusted complication rates, hospital length-of-stay (H-LOS), and ICU-LOS. Descriptive statistics and multivariable regression with reliability adjustments to account for variations in practice were performed. RESULTS Of 4149 patients analyzed, 3571 (86.1%) underwent laparotomy, 489 (11.8%) underwent laparoscopy, and 89 (2.1%) underwent laparoscopy-to-laparotomy conversion. Adjusted mortality rates were not significantly different among all study cohorts (P > .05). Compared to laparoscopy, adjusted odds of complications were 4.3-fold higher for all patients who underwent laparotomy and 4-fold higher for laparoscopy-to-laparotomy (LtL) patients (P < .05). Diaphragmatic injuries were associated with significantly increased odds of undergoing LtL, whereas sustaining a colonic injury, gastric injury, hepatic injury, or requiring PRBC transfusions were associated with significantly increased odds of undergoing laparotomy (P < .05). H-LOS (days) was significantly longer for patients who underwent laparotomy compared to laparoscopy (3.9 ± 4.0 vs. 10.8 ± 13.4, P < .0001). CONCLUSIONS Laparoscopy may be considered a viable alternative to laparotomy for hemodynamically stable adult patients with single penetrating LUQ injuries of low injury burden validating our hypothesis. Laparoscopy may be less safe for patients with associated diaphragmatic, colonic, or hepatic injuries.

Abstract
INTRODUCTION Traumatic brain injury (TBI), a leading cause of morbidity and mortality among trauma patients worldwide, poses the risk of secondary neurological insult due to significant catecholamine surge. We aim to investigate the effectiveness and outcomes of beta-blocker administration in patients with severe TBI. METHODS A search through PubMed, EMBASE, JAMA network, and Google Scholar databases was conducted for relevant peer-reviewed original studies published before February 15, 2022. A standard random-effects model was used, as justified by a high Cohen's Q test. RESULTS Twelve studies met inclusion criteria and were included in the meta-analysis. Severe TBI patients who were administered beta-blockers had a significantly reduced incidence of in-hospital mortality compared to the non-beta-blocker group (14.5% vs 19.2%). However, the beta-blocker group was reported to have a significantly greater number of ventilator days (5.58 vs 2.60 days). Similarly, intensive care unit (9.00 vs 6.84 days) and hospital (17.30 vs 11.02 days) lengths of stay (LOS) were increased in the beta-blocker group compared to those who were not administered beta-blocker therapy, but only the difference in hospital-LOS was significant. CONCLUSIONS Beta-blockers have significantly decreased in-hospital mortality in patients with severe TBI despite being associated with an increase in ventilator days and hospital-LOS. The administration of beta-blocker therapy in the management of severe TBI may be warranted and should be discussed in future guidelines.

Abstract
BACKGROUND Opioids have been proven effective in pain management, but overprescription can lead to addiction and abuse. Although current guidelines regarding opioid prescription for chronic and acute pain are available, they fail to address the use of opioids for pain management in traumatic injury patients who undergo operations. The primary objective of this study was to examine opioid prescribing practices for US adult trauma patients who require surgical management, based on prior history of opioid use, type of surgical practice, and age. METHODS PubMed and Cochrane Journals were used to identify relevant articles between October 2010 and December 29, 2020. Our primary outcome was discrepancies of morphine milligram equivalents (MMEs) prescribed to trauma patients. Significance was defined as p < 0.05. RESULTS Eleven studies on US trauma patients prescribed opioids were evaluated, creating a total of 30,249 patients stratified by prior opioid use, age, and race. Patterns seen among patients with prior opioid use include higher MMEs prescribed, lower likelihoods of opioid discontinuation, higher mortality rates, and higher complication rates. Orthopedic surgeons prescribed higher values of MMEs than nonorthopedic surgeons. CONCLUSION Higher incidences of opioid prescriptions are seen with orthopedic trauma surgery and prior opioid use by the patient. We recommend further development of national protocol implementation for acute pain management for the US trauma population. LEVEL OF EVIDENCE Systematic review, level III.

Abstract
BACKGROUND There is a lack of literature regarding the most effective timing to initiate physical therapy (PT) among traumatically injured patients. We aim to evaluate the association between early PT/mobilization versus delayed or late PT/mobilization and clinical outcomes of trauma patients. METHODS A retrospective cohort analysis of an urban level-I trauma center from 2014 to 2019 was performed. Univariate analyses and multivariable logistic regression were performed with significance defined as P < 0.05. RESULTS A total of 11,937 patients were analyzed. Among patients without a traumatic brain injury (TBI), late PT initiation times were associated with 60% lower odds of being discharged home without services (P < 0.05), significantly increased hospital and ICU length of stay (H-LOS, ICU-LOS) (P < 0.05), and significantly higher odds of complications (VTE, pneumonia, pressure ulcers, ARDS) (P < 0.001). Among patients with a TBI, late PT initiation time had 76% lower odds of being discharged home without services (P < 0.05) and significantly longer H-LOS and ICU-LOS (P < 0.05) however did not experience significantly higher odds of complications (P > 0.05). CONCLUSIONS Among traumatically injured patients, early PT is associated with decreased odds of complications, shorter H-LOS and ICU-LOS, and a favorable discharge disposition to home without services. Adoption of early PT initiation/mobilization protocols and establishment of prophylactic measures against complications associated with delayed PT is critical to maximize quality of care and trauma patient outcomes. Multi-center prospective studies are needed to ascertain the impact of PT initiation times in greater detail and to minimize trauma patient morbidity.

Abstract
BACKGROUND To match medical students into residency training programs, both the program and student create rank order lists (ROLs). We aim to investigate temporal trends in ROL lengths across 7 match cycles between 2014 and 2021 for both matched and unmatched residency applicants and programs. METHODS retrospective study of ROLs of 7 match cycles, 2014-2021. Residency match and ROL data were extracted from the NRMP database to assess the number of programs filled and unfilled, length of ROLs, position matched, and average ranks per position for osteopathic (DO) and allopathic (MD) medical programs. RESULTS For filled residency programs, the average ROL length consistently increased from 70.72 in 2015 to 88.73 in 2021 (P = .003), with ROL lengths consistently longer for filled vs unfilled residency programs (P < .001). The average ROL length for matched applicants increased consistently from 10.41 in 2015 to 12.35 in 2021 (P = .002), with matched applicants having consistently longer ROLs than unmatched applicants (P < .001). From 2015 to 2021, in both MD and DO applicants, progressively lower proportions of applicants matched their first and second choices. CONCLUSION Trends across the past 7 residency match cycles suggest that ROL lengths for both programs and applicants have been increasing with matched programs and applicants submitting significantly longer ROLs than unmatched applicants. Additionally, fewer applicants are matching at their preferred programs over time. Our findings support the mounting evidence that the Match has become increasingly congested and we discuss the possible factors that may be contributing to the current state of the Match as well as potential solutions.

Abstract
The purpose of this systematic review was to study 4 different aspects of Roux-en-Y gastric bypass (RYBG) and sleeve gastrectomy (SG). Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are two commonly performed bariatric procedures. This systematic review aims to compare RYGB with SG when it comes to weight changes, and cardiometabolic risk profile. Another aim was to evaluate laparoscopic and robotic techniques for both surgeries. PubMED, Cochrane Library, and JAMA Network were searched for articles evaluating RYGB and SG from 2005-2020. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. Four different categories were analyzed comparing RYGB with SG as well as robotic versus laparoscopic approach. The Critical Appraisal Skills Program (CASP) checklist was used to assess the quality of evidence in the studies included in this systematic review. A total of 29 studies were included looking at different aspects of RYGB and SG. RYGB is superior to SG for weight loss, improved or complete remission of cholesterol and hypertensive medications. Consensus is lacking regarding decrease in BMI, total cholesterol, and triglycerides. There is lack of evidence regarding decrease of incidence of MI or stroke. For RYGB and SG, the majority of studies found that the robotic technique was more expensive and took longer. RYGB when compared with SG was associated with larger weight loss, decreased or cessation of cholesterol and hypertensive medications, and lower cholesterol. Decrease in BMI had varying results, with RYGB being superior in more studies, while there was no difference in other studies. There was a lack of evidence to support if RYGB or SG was superior to decreasing triglyceride levels. For both RYGB and SG, the robotic approach was costlier and took more operating time versus the laparoscopic approach.

Abstract
e15135 Background: While the use of monoclonal antibodies targeting the PD-1 axis in metastatic non-small cell lung cancer (NSCLC) continues to expand since initial FDA approval in 2015, factors predictive of response still remain to be determined. Mutation status may provide insight as to which subgroups exhibit resistance to checkpoint inhibitor therapy. Methods: We conducted a single center retrospective analysis of patients with metastatic NSCLC treated at the University of Miami / Sylvester Comprehensive Cancer Center who underwent next-generation sequencing (NGS) and identified patients that harbor either STK11 mutation alone (S) or co-mutations with STK11 and KRAS (S/K). Genomic results were obtained from Guardant360 and Foundation One testing in blood and tissue, respectively. Results: We identified 37 S patients and 36 S/K patients and determined no significant differences in progression-free survival (PFS). However, overall survival (OS) was significantly increased in patients with S/K co-mutation (20.3 ± 4.1 months) vs. patients with S alone (11.9 ± 1.9 months, p = 0.028). Furthermore, S/K patients who received immunotherapy had longer OS (20.7 ± 5.6 months) vs. S patients (13.6 ± 3.4 months, p = 0.049). We further investigated any population-specific factors that may contribute to the enhanced survival in the S/K cohort that had received immunotherapy, as previous studies have reported that STK11/KRAS co-mutations may confer a resistance to PD-1 axis-directed therapy. We found that S/K patients were older at diagnosis and were more likely to have received nivolumab (as compared to newer therapies pembrolizumab and atezolizumab). In addition, S/K patients were more likely to have longer smoking histories (81% smoked more than 30 pack-years at diagnosis) vs. S patients (53%, p = 0.01) and also had a higher number of additional targetable mutations found on NGS (4.7 ± 0.4 vs. 2.9 ± 0.3, p = 0.001). The most commonly identified mutations were TP53 (30%), KEAP1 (19%), CDKN2A/B (18%), SMARCA4/BRG1 (16%), and ARID1A (11%). Conclusions: Our study reveals an interesting analysis of potential predictors of resistance to immunotherapy with the utilization of precision medicine in combination with patient characteristics to identify the most appropriate treatment regimens for patients with NSCLC. Further studies will explore whether patients receiving immunotherapy as first line could overcome any inherent resistance to PD-1 axis-directed therapy from non-modifiable factors at diagnosis.

Abstract
e21547 Background: While genetic profiling has become standard of care for patients diagnosed with non-small cell lung cancer (NSCLC), next-generation sequencing (NGS) provides a wealth of information about targetable mutations. Advances in genetic testing have led to sequencing platforms that utilize tissue itself or extracellular circulating tumor DNA in the blood, known as a “liquid biopsy.” Methods: We identified 55 patients with NSCLC who had undergone both tissue and liquid biopsy, using Foundation One and Guardant 360 at the University of Miami / Sylvester Comprehensive Cancer Center between January 2016 and December 2018, and performed retrospective analysis to determine patient characteristics as well concordance between different NGS platforms. Results: In our patient population, 34% of patients had never smoked prior to diagnosis, while 22% had more than a 30 pack-year smoking history. 64% of patients had no treatment prior to initial NGS. 40% of patients had both testing done essentially simultaneously, while 60% of patients had one test done after disease progression. Of these patients, therapy was changed as a result in 73%. Median number of days between tests was 21 days, with 56% of testing done within 90 days of the previous testing. Nine patients had an additional Foundation One tissue NGS performed. Concordance across all genes tested in both platforms was 98 ± 0.2%. Concordance with consideration of genetic alterations detected in both assays was 24.5 ± 3.0%. The median number of gene alterations determined by Foundation One testing was 4 (range 1-9), while the median for gene alterations detected by Guardant 360 was 3 (range 1-13). The median number of variants of unknown significance (VUS) was 10 (range 5-25). Conclusions: Our analysis indicates a role for both tissue-based and circulating tumor DNA-based NGS for determination of targetable mutations and thus appropriate treatment regimens. Low levels of concordance are potentially related to post-treatment changes in the tumor genetic profile as well as evolution in the testing itself.

Abstract
e17098 Background: Next Generation Sequencing (NGS) guides targeted therapy and clinical trial enrollment for patients with gynecologic malignancies. South Florida is a key region to explore biomarkers and molecular alterations common in Hispanic (H) patients due to the high proportion of H individuals. While NGS testing is increasingly used in clinical practice to aid in treatment planning, ethnic minorities are at risk for health disparity including clinical trial enrollment. The objective of this study was to determine if frequently reported mutations are also common in a predominantly H population with gynecologic cancers. Methods: Clinicopathologic data was obtained from women treated at our institution from Jan. 2014 to Jan 2019 for gynecologic malignancies. Women with ovarian (OC), endometrial (EC), and cervical cancer (CC) with NGS results from Caris Life Sciences were included for analysis. Women self-report ethnicity based on initial hospital intake form. Mutations based on point mutations, indels, fusions and copy number variations were identified. Descriptive statistics are reported. IRB approval was obtained. Results: A total of 233 patients with 117 ovarian (OC), 24 cervical (CC) and 92 endometrial cancers (EC) were included. Among the 233 women, 96 (41%) were H, 137 (59%) identified as NH. There were 38 H and 48 NH patients with EC; 50 H and 62 NH OC patients; and 8 H and 13 NH CC patients. Among EC patients, TP53 appeared in 42% vs. 47%, PTEN 26% vs. 30% , PIK3CA 32% vs. 17%, CTNNB1 32% vs. 17% , and KRAS 16% vs. 21% of H and NH cases respectively. In the OC cohort, TP53 appeared in 74% vs. 75% , BRCA1/2 10% vs. 19%, KRAS 16% vs. 16% and PIK3CA 8% vs. 6% of H and NH cases respectively. In CC patients, TP53 appeared in 25% vs. 23%, KMT2C 12.5% vs. 7.6% and PIK3CA 0 vs. 38% of H and NH cases respectively. There were no statistical differences in the mutation rates between the two groups. Conclusions: There is limited data reported on the variation of mutations based on ethnicity in women with gynecologic cancers. Our study suggests there may be different driver mutations based on ethnicity. Future studies in larger cohorts are needed to further assess genomic differences, potential responses to treatment and further increase H population enrollment into clinical trials.
