Item 4355 Impact of Demographic & Racial Differences on DNA Repair Capacity in Lung Cancer(Cambridge University Press, 2020-07-29) Duncan, Francesca Christina; Sears, Catherine; Al Narallah, Nawar; Al-Hader, Ahmad; Medicine, School of MedicineOBJECTIVES/GOALS: Lung cancer is the leading cause of cancer-related mortality in the United States for both men and women. African Americans are disproportionately affected with lung cancer, having higher incidence and mortality rates compared to Caucasian men and women. African American smokers are diagnosed with lung cancer at a lower age with lower cumulative smoking history. Differences in socioeconomic and environmental factors likely contribute to lung cancer disparities, but less is known about acquired biologic alterations that can promote initiation and progression of lung cancer, particularly in African Americans. This is of interest because there may be other biological, genetic, or environmental factors contributing to lung cancer outcomes as it relates to differences in gender and race. One potential biologic variable may be in the DNA repair capacity (DRC), which describes a cell’s ability to repair damage to DNA caused by carcinogens, oxidants, and radiation. Altered DNA repair is a hallmark of cancer, leading to mutations and malignant transformation. We hypothesize that DRC is decreased in African Americans with lung cancer compared to Caucasian Americans with lung cancer, contributing to the disparity that exists in this racial group. We will 1) perform a retrospective chart review to determine demographic differences between African Americans and Caucasians at three central Indiana hospitals and 2) determine the impact of race and lung cancer on DRC amongst African Americans and Caucasians with and without lung cancer. METHODS/STUDY POPULATION: Lung cancer patients are identified in 3 central Indiana hospitals with different payer source and patient populations using ICD codes. Collected demographics include age, gender, pack-years, lung cancer histology, treatment, and mortality. DRC is measured by host-cell reactivation (non-homologous end-joining and nucleotide excision repair pathways) by flow-cytometry. Measurement of DRC is performed on PBMCs obtained from 120 patients (male and female, African Americans and Caucasians with and without lung cancer). Correlation of DRC and lung cancer will be determined by comparing lung cancer diagnosis to quartile DRC, and adjusted for confounders (measured demographics). Correlative measures will include measures of DNA damage and genomic instability. RESULTS/ANTICIPATED RESULTS: 3450 lung cancer patients were diagnosed with lung cancer at Indiana University Hospital between 1/1/2000 – 5/31/2015. Of these, 48.2% were female and 92.7% smokers. African Americans, Caucasians and Other ethnicities represented 12%, 86% and 2%, respectively. Of smokers, 11.4% were African American. The primary payer source was Federal/Medicare. Retrospective review of lung cancer patients from two additional health systems (county and VA hospitals) will be performed as above with outcomes measured. DRC and additional correlative measures will be performed as in Methods. DISCUSSION/SIGNIFICANCE OF IMPACT: If present, altered DRC in African Americans compared to Caucasians may contribute to the disproportional impact of lung cancer on African Americans. If DRC is decreased in African Americans with lung cancer, future studies will focus on identifying potential genetic, epigenetic and environmental causes for this decrease.Item Clinical Outcomes Among Immunotherapy-Treated Patients With Primary Cardiac Soft Tissue Sarcomas: A Multicenter Retrospective Study(Elsevier, 2024-01-16) Nassar, Amin H.; El-Am, Edward; Denu, Ryan; Alaiwi, Sarah Abou; El Zarif, Talal; Macaron, Walid; Abdel-Wahab, Noha; Desai, Aakash; Smith, Caleb; Parikh, Kaushal; Abbasi, Muhannad; Farhat, Elias Bou; Williams, James M.; Collins, Jeremy D.; Al-Hader, Ahmad; McKay, Rana R.; Malvar, Carmel; Sabra, Mohamad; Zhong, Caiwei; El Alam, Raquelle; Chehab, Omar; Lima, Joao; Phan, Minh; Pria, Hanna Ferreira Dalla; Trevino, Alexandra; Neilan, Tomas G.; Kwan, Jennifer M.; Ravi, Vinod; Deshpande, Hari; Demetri, George; Choueiri, Toni K.; Naqash, Abdul Rafeh; Medicine, School of MedicineBackground: Primary cardiac soft tissue sarcomas (CSTS) affect young adults, with dismal outcomes. Objectives: The aim of this study was to investigate the clinical outcomes of patients with CSTS receiving immune checkpoint inhibitors (ICIs). Methods: A retrospective, multi-institutional cohort study was conducted among patients with CSTS between 2015 and 2022. The patients were treated with ICI-based regimens. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Objective response rates were determined according to Response Evaluation Criteria in Solid Tumors version 1.1. Treatment-related adverse events were graded per the Common Terminology Criteria for Adverse Events version 5.0. Results: Among 24 patients with CSTS, 17 (70.8%) were White, and 13 (54.2%) were male. Eight patients (33.3%) had angiosarcoma. At the time of ICI treatment, 18 patients (75.0%) had metastatic CSTS, and 4 (16.7%) had locally advanced disease. ICIs were administered as the first-line therapy in 6 patients (25.0%) and as the second-line therapy or beyond in 18 patients (75.0%). For the 18 patients with available response data, objective response rate was 11.1% (n = 2 of 18). The median PFS and median OS in advanced and metastatic CSTS (n = 22) were 5.7 months (95% CI: 2.8-13.3 months) and 14.9 months (95% CI: 5.7-23.7 months), respectively. The median PFS and OS were significantly shorter in patients with cardiac angiosarcomas than in those with nonangiosarcoma CSTS: median PFS was 1.7 vs 11 months, respectively (P < 0.0001), and median OS was 3.0 vs 24.0 months, respectively (P = 0.008). Any grade treatment-related adverse events occurred exclusively in the 15 patients with nonangiosarcoma CSTS (n = 7 [46.7%]), of which 6 (40.0%) were grade ≥3. Conclusions: Although ICIs demonstrate modest activity in CSTS, durable benefit was observed in a subset of patients with nonangiosarcoma, albeit with higher toxicity.Item Emergency department associated lung cancer diagnosis: Case series demonstrating poor outcomes and opportunities to improve cancer care(Elsevier, 2021) Pettit, Nicholas; Al-Hader, Ahmad; Thompson, Caroline A.; Emergency Medicine, School of MedicineThe diagnosis of cancer through an emergency presentation of an undiagnosed malignancy constitutes around 20–50% of first-time cancer diagnoses. There is a paucity of evidence on the emergency presentations of undiagnosed malignancy with only a few epidemiological studies of large administrative databases. Limited administrative data has shown patients diagnosed with cancer after an emergency presentation suffer poorer clinical outcomes as compared to those diagnosed with cancer through elective routes. Further those diagnosed emergently are commonly among vulnerable populations, such as based on socioeconomic status and racial/ethnic groups. Lung cancer is the most common cancer diagnosed emergently, and while one of the most preventable and treatable, often presents to an emergency department in extremis. This case study of six patients seeks to augment administrative database research by adding detailed clinical information as to demonstrate the issues with diagnosing lung cancer through an emergency presentation. We found that patients diagnosed emergently have complex care pathways including delayed biopsies, delayed treatments, and poor outcomes. Research is needed to elucidate the optimal path on how to manage suspected lung cancer diagnoses from the emergency department.Item Examining adherence to oral anticancer medications through a human factors engineering framework: Protocol for a scoping review(PLOS, 2022-09-22) Lin, Irene D.; Shotts, Matthew B.; Al-Hader, Ahmad; Weddle, Kellie Jones; Holden, Richard J.; Mueller, Emily L.; Macik, Monica R.; Ramirez, Mirian; Abebe, Ephrem; Medicine, School of MedicineBackground The number of oral anticancer medications has increased over the past few decades, opening new possibilities in cancer care and improving convenience for patients and caregivers. However, adherence levels continue to be suboptimal, potentially jeopardizing therapeutic benefits. Poor adherence levels may indicate gaps in current strategies and interventions aimed at enhancing medication adherence and the extent to which they address the complex and multi-faceted medication management needs of patients and their caregivers. Beyond commonly understood barriers (e.g., forgetting to take medications), adherence interventions must address systemic barriers that may not be fully appreciated by members of the healthcare system. This scoping review aims to apply a systems framework (human factors engineering framework) to examine system elements targeted by adherence enhancing interventions. Methods Studies published in English, reporting adherence interventions for oral anticancer medications with adherence and/or persistence as primary outcome measures will be included in this review. We will search the following electronic databases with no limits on dates: Ovid MEDLINE, Cochrane Library, Web of Science Core Collection, Embase, CINAHL Complete, PsycInfo, and Scopus. Two reviewers will independently screen study titles and abstracts for inclusion with a third reviewer adjudicating conflicts. Full text of included articles will be used to extract information on systemic barriers targeted by adherence interventions as well as information about intervention type, outcomes, and study characteristics. Extracted information will be synthesized to generate a summary of work system factors targeted by adherence interventions. Discussion Through application of a systems-based approach, this scoping review is expected to shed light on the complex and multifaceted nature of factors influencing adherence to oral anticancer agents. The review may also identify areas that are ripe for further research.Item Hemophagocytic Lymphohistiocytosis in the Medical ICU: A Single-Institution Cohort Study on Acute Liver Failure and Mortality(Wolters Kluwer, 2021-01-08) Al Nasrallah, Nawar; Al-Hader, Ahmad; Samala, Niharika; Sears, Catherine R.; Medicine, School of MedicineHemophagocytic lymphohistiocytosis is a life-threatening hyperinflammatory disorder that is associated with high morbidity and mortality in the ICU. It has also been associated with acute liver failure. Design: Retrospective observational study. Setting: Tertiary-care medical ICU. Patients: Thirty-one patients critically ill with hemophagocytic lymphohistiocytosis. Interventions: None. Measurements and main results: We performed a comprehensive review of critically ill hemophagocytic lymphohistiocytosis patients admitted to a tertiary-care medical ICU from January 2012 to December 2018. Most patients presented with constitutional symptoms and elevated liver enzymes and thrombocytopenia were common upon hospital admission. ICU admission laboratory and clinical variables were used to calculate Acute Physiology and Chronic Health Evaluation II, hemophagocytic syndrome diagnostic score, and model for end-stage liver disease. Mean age of the cohort was 48.1 years, and 45% were male. The mortality rate was 65% at 28 days and 77% at 1 year. About 28-day survivors were younger, had lower mean Acute Physiology and Chronic Health Evaluation II score (16.5 vs 23.0; p = 0.004), and higher mean hemophagocytic syndrome diagnostic score (249.1 vs 226.0; p = 0.032) compared with nonsurvivors. Survivors were less likely to receive mechanical ventilation, renal replacement therapy, or vasopressor support and were more likely to receive chemotherapy for hemophagocytic lymphohistiocytosis. In this ICU cohort, 29% were diagnosed with acute liver failure, of whom only 22% developed acute liver failure early during their hospital stay. Acute liver failure was associated with a higher model for end-stage liver disease score upon hospital admission. Available histology in those that developed acute liver failure showed massive hepatic necrosis, or histiocytic or lymphocytic infiltrates. Conclusions: Patients admitted to the ICU with hemophagocytic lymphohistiocytosis have a high mortality. Those who survived had lower Acute Physiology and Chronic Health Evaluation scores, had higher hemophagocytic syndrome diagnostic scores, are more likely to receive hemophagocytic lymphohistiocytosis specific chemotherapy, and are less likely to have organ failure. Hemophagocytic lymphohistiocytosis can be associated with acute liver failure especially when model for end-stage liver disease score is elevated upon admission.Item Malignant gastrointestinal neuroectodermal tumour arising in the extrahepatic bile ducts; a rare neoplasm in an unusual anatomic location(BMJ, 2022-07-20) Miller, C. Quinn; Al-Hader, Ahmad; Vance, Gail H.; Zhang, Chen; Pathology and Laboratory Medicine, School of MedicineMalignant gastrointestinal neuroectodermal tumour (GNET) is a rare, aggressive neoplasm with fewer than 100 cases reported in the literature. Most cases arise in the tubular gastrointestinal tract. We reported a unique case of GNET arising in the extrahepatic bile ducts and reviewed the literature of GNETs. The patient is a female in her mid-30s who presented with painless jaundice and diarrhoea several months after cholecystectomy for biliary dyskinesia. Workup revealed a tumour arising from the peripheral 4B bile ducts involving the left hepatic duct and bifurcation. Histologic examination of the lesion showed a malignant spindled and epithelioid neoplasm which strongly expressed S100 and SOX-10. Neoplastic cells were negative for various cytokeratins and melanoma markers. FISH testing using EWSR1 break-apart probes showed rearrangement of the EWSR1 gene region. The immunohistochemical and molecular findings are consistent with a diagnosis of GNET arising in the extrahepatic bile ducts.Item Pancreatic acinar cell carcinoma: A review on molecular profiling of patient tumors(Baishideng Publishing Group, 2017-12-07) Al-Hader, Ahmad; Al-Rohil, Rami N; Han, Haiyong; Von Hoff, Daniel; Medicine, School of MedicinePancreatic carcinomas with acinar differentiation are rare, accounting for 1%-2% of adult pancreatic tumors; they include pancreatic acinar cell carcinoma (PACC), pancreatoblastoma, and carcinomas of mixed differentiation. Patients with PACC have a prognosis better than pancreatic ductal adenocarcinomas but worse than pancreatic neuroendocrine tumors. Reports of overall survival range from 18 to 47 mo. A literature review on PACCs included comprehensive genomic profiling and whole exome sequencing on a series of more than 70 patients as well as other diagnostic studies including immunohistochemistry. Surgical resection of PACC is the preferred treatment for localized and resectable tumors. The efficacy of adjuvant treatment is unclear. Metastatic PACCs are generally not curable and treated with systemic chemotherapy. They are moderately responsive to chemotherapy with different regimens showing various degrees of response in case reports/series. Most of these regimens were developed to treat patients with pancreatic ductal adenocarcinomas or colorectal adenocarcinomas. Review of PACC’s molecular profiling showed a number of gene alterations such as: SMAD4, BRAF, BRCA2, TP53, RB1, MEN1, JAK-1, BRCA-1, BRCA-2, and DNA mismatch repair abnormalities. PACCs had multiple somatic mutations with some targetable with available drugs. Therefore, molecular profiling of PACC should be an option for patients with refractory PACC.Item Racial disparities in staging, treatment, and mortality in non-small cell lung cancer(AME, 2024) Duncan, Francesca C.; Al Nasrallah, Nawar; Nephew, Lauren; Han, Yan; Killion, Andrew; Liu, Hao; Al-Hader, Ahmad; Sears, Catherine R.; Medicine, School of MedicineBackground: Black race is associated with advanced stage at diagnosis and increased mortality in non-small cell lung cancer (NSCLC). Most studies focus on race alone, without accounting for social determinants of health (SDOH). We explored the hypothesis that racial disparities in stage at diagnosis and outcomes are associated with SDOH and influence treatment decisions by patients and providers. Methods: Patients with NSCLC newly diagnosed at Indiana University Simon Comprehensive Cancer Center (IUSCCC) from January 1, 2000 to May 31, 2015 were studied. Multivariable regression analyses were conducted to examine the impact of SDOH (race, gender, insurance status, and marital status) on diagnosis stage, time to treatment, receipt of and reasons for not receiving guideline concordant treatment, and 5-year overall survival (OS) based on Kaplan-Meier curves. Results: A total of 3,349 subjects were included in the study, 12.2% of Black race. Those diagnosed with advanced-stage NSCLC had a significantly higher odds of being male, uninsured, and Black. Five-year OS was lower in those of Black race, male, single, uninsured, Medicare/Medicaid insurance, and advanced stage. Adjusted for multiple variables, individuals with Medicare, Medicare/Medicaid, uninsured, widowed, and advanced stage at diagnosis, were associated with significantly lower OS time. Black, single, widowed, and uninsured individuals were less likely to receive stage appropriate treatment for advanced disease. Those uninsured [odds ratio (OR): 3.876, P<0.001], Medicaid insurance (OR: 3.039, P=0.0017), and of Black race (OR: 1.779, P=0.0377) were less likely to receive curative-intent surgery for early-stage NSCLC because it was not a recommended treatment. Conclusions: We found racial, gender, and socioeconomic disparities in NSCLC diagnosis stage, receipt of stage-appropriate treatment, and reasons for guideline discordance in receipt of curative intent surgery for early-stage NSCLC. While insurance type and marital status were associated with worse OS, race alone was not. This suggests racial differences in outcomes may not be associated with race alone, but rather worse SDOH disproportionately affecting Black individuals. Efforts to understand advanced diagnosis and reasons for failure to receive stage-appropriate treatment by vulnerable populations is needed to ensure equitable NSCLC care.Item Safety and Activity of Immune Checkpoint Inhibitors in People Living With HIV and Cancer: A Real-World Report From the Cancer Therapy Using Checkpoint Inhibitors in People Living With HIV-International (CATCH-IT) Consortium(American Society of Clinical Oncology, 2023) El Zarif, Talal; Nassar, Amin H.; Adib, Elio; Fitzgerald, Bailey G.; Huang, Jiaming; Mouhieddine, Tarek H.; Rubinstein, Paul G.; Nonato, Taylor; McKay, Rana R.; Li, Mingjia; Mittra, Arjun; Owen, Dwight H.; Baiocchi, Robert A.; Lorentsen, Michael; Dittus, Christopher; Dizman, Nazli; Falohun, Adewunmi; Abdel-Wahab, Noha; Diab, Adi; Bankapur, Anand; Reed, Alexandra; Kim, Chul; Arora, Aakriti; Shah, Neil J.; El-Am, Edward; Kozaily, Elie; Abdallah, Wassim; Al-Hader, Ahmad; Ghazal, Batool Abu; Saeed, Anwaar; Drolen, Claire; Lechner, Melissa G.; Drakaki, Alexandra; Baena, Javier; Nebhan, Caroline A.; Haykal, Tarek; Morse, Michael A.; Cortellini, Alessio; Pinato, David J.; Pria, Alessia Dalla; Hall, Evan; Bakalov, Veli; Bahary, Nathan; Rajkumar, Aarthi; Mangla, Ankit; Shah, Vishal; Singh, Parminder; Nana, Frank Aboubakar; Lopetegui-Lia, Nerea; Dima, Danai; Dobbs, Ryan W.; Funchain, Pauline; Saleem, Rabia; Woodford, Rachel; Long, Georgina V.; Menzies, Alexander M.; Genova, Carlo; Barletta, Giulia; Puri, Sonam; Florou, Vaia; Idossa, Dame; Saponara, Maristella; Queirolo, Paola; Lamberti, Giuseppe; Addeo, Alfredo; Bersanelli, Melissa; Freeman, Dory; Xie, Wanling; Reid, Erin G.; Chiao, Elizabeth Y.; Sharon, Elad; Johnson, Douglas B.; Ramaswami, Ramya; Bower, Mark; Emu, Brinda; Marron, Thomas U.; Choueiri, Toni K.; Baden, Lindsey R.; Lurain, Kathryn; Sonpavde, Guru P.; Naqash, Abdul Rafeh; Graduate Medical Education, School of MedicinePurpose: Compared with people living without HIV (PWOH), people living with HIV (PWH) and cancer have traditionally been excluded from immune checkpoint inhibitor (ICI) trials. Furthermore, there is a paucity of real-world data on the use of ICIs in PWH and cancer. Methods: This retrospective study included PWH treated with anti-PD-1- or anti-PD-L1-based therapies for advanced cancers. Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Objective response rates (ORRs) were measured per RECIST 1.1 or other tumor-specific criteria, whenever feasible. Restricted mean survival time (RMST) was used to compare OS and PFS between matched PWH and PWOH with metastatic NSCLC (mNSCLC). Results: Among 390 PWH, median age was 58 years, 85% (n = 331) were males, 36% (n = 138) were Black; 70% (n = 274) received anti-PD-1/anti-PD-L1 monotherapy. Most common cancers were NSCLC (28%, n = 111), hepatocellular carcinoma ([HCC]; 11%, n = 44), and head and neck squamous cell carcinoma (HNSCC; 10%, n = 39). Seventy percent (152/216) had CD4+ T cell counts ≥200 cells/µL, and 94% (179/190) had HIV viral load <400 copies/mL. Twenty percent (79/390) had any grade immune-related adverse events (irAEs) and 7.7% (30/390) had grade ≥3 irAEs. ORRs were 69% (nonmelanoma skin cancer), 31% (NSCLC), 16% (HCC), and 11% (HNSCC). In the matched mNSCLC cohort (61 PWH v 110 PWOH), 20% (12/61) PWH and 22% (24/110) PWOH had irAEs. Adjusted 42-month RMST difference was -0.06 months (95% CI, -5.49 to 5.37; P = .98) for PFS and 2.23 months (95% CI, -4.02 to 8.48; P = .48) for OS. Conclusion: Among PWH, ICIs demonstrated differential activity across cancer types with no excess toxicity. Safety and activity of ICIs were similar between matched cohorts of PWH and PWOH with mNSCLC.Item Superior vena cava syndrome in a patient with locally advanced lung cancer with good response to definitive chemoradiation: a case report(Biomed Central, 2018-10-20) Hinton, Jason; Cerra-Franco, Alberto; Shiue, Kevin; Shea, Lindsey; Aaron, Vasantha; Billows, Geoffrey; Al-Hader, Ahmad; Lautenschlaeger, Tim; Radiation Oncology, School of MedicineBACKGROUND: The incidence of superior vena cava syndrome within the United States is roughly 15,000 cases per year. Superior vena cava syndrome is a potentially life-threatening medical condition; however, superior vena cava syndrome is not fatal in the majority of cases. Superior vena cava syndrome encompasses a collection of signs and symptoms resulting from obstruction of the superior vena cava, including swelling of the upper body of the head, neck, arms, and/or breast. It is also associated with cyanosis, plethora, and distended subcutaneous vessels. Lung cancer, including both non-small cell lung cancer and small cell lung cancer, is the most common extrinsic cause of superior vena cava syndrome. Intrinsic disruption of superior vena cava flow can also precipitate superior vena cava syndrome. This case report describes an unusual presentation and potential etiology of superior vena cava syndrome. CASE PRESENTATION: Our patient was a 51-year-old black woman with locally advanced, stage IIIB non-small cell lung cancer who had no clinical symptoms of superior vena cava syndrome at the time of diagnosis. However, she did have radiographic evidence of superior vena cava stenosis caused by extrinsic compression from her large right hilar primary tumor. She was treated with definitive chemoradiation, receiving 60 Gy of external beam radiation therapy given concurrently with chemotherapy. Three months after completion of radiotherapy, she developed signs of superior vena cava syndrome, including breast and supraclavicular swelling. She had a chest computed tomography scan showing over 50% reduction in the size of a right hilar mass; however, she had continued radiographic stenosis of the superior vena cava. The distribution of stenosis appeared to be inferior to the caudal extent of pretreatment tumor volume. She had no other radiographic indications for superior vena cava syndrome. CONCLUSIONS: Generally, superior vena cava syndrome is the result of extrinsic compression of the superior vena cava by tumor. Our patient's case represents the development of superior vena cava syndrome after an excellent response of tumor with near-complete tumor response. We suspect chemoradiation therapy as a potential etiology for the precipitation of the superior vena cava syndrome, which is currently not well reported in the medical literature.
