e23275 Background: Multimodal therapy, including definitive radiotherapy (RT) with or without systemic therapy (ST) or surgery followed by adjuvant RT ± ST is typically recommended for patients (pts) with LA HNSCC treated with curative intent. Assessing real-world use of various treatment modalities and OS helps to better understand the unmet needs in this population. Methods: The linked SEER-Medicare data (2007–2019) was used in this retrospective cohort study. Pts with newly diagnosed stage III-IVB (AJCC 6/7th) LA HNSCC (larynx, hypopharynx, oral cavity, or oropharynx) who received primary treatment within 4 months after initial diagnosis were included. HPV status was not available. OS from index date, i.e., primary treatment initiation date, was described using the Kaplan-Meier method. Baseline (12 months prior to index date) factors associated with OS were assessed using a Cox proportional hazards model. Hazard ratios (HRs), 95% confidence intervals (CIs), and p values were reported. Results: In total, 1885 pts met the selection criteria (median follow-up: 24.8 months). The mean age at initial diagnosis was 74.3 years, 67.2% were male, and 81.6% were white. Less than 1/3rd of pts received primary surgery (resected). More than half of resected pts received RT±ST post-surgery. In unresected pts, nearly 2/3rds received definitive concurrent RT+ST. The median OS and 5-year OS were 32.7 months and 37.6%, respectively, for all pts and were comparable between resected and unresected pts. In the multivariable Cox models for both resected and unresected pts, older age, more advanced tumor stage, hypopharynx (vs. oropharynx), and higher Charlson comorbidity index scores were associated with significantly shorter survival. Additionally, surgery followed by RT+ST (vs. surgery only) (HR = 0.50, 95% CI = 0.34-0.72, p < 0.001) and definitive RT+ST (vs. definitive RT only) (HR = 0.69, 95% CI = 0.58-0.81, p < 0.001) were associated with significantly longer survival in resected and unresected pts, respectively. Conclusions: In elderly pts with LA HNSCC, surgery followed by RT and definitive RT+ST were the most common treatment modalities in resected and unresected pts, respectively. The suboptimal real-world survival across all pts with LA HNSCC regardless of treatment strategy highlights a significant unmet need. Studies focused on the novel application and sequencing of effective immunotherapies are needed. Table 1. Primary treatment and OS in LA HNSCC1 [Table: see text]

Published: June 2024

e23283 Background: In a concerted effort to enhance the quality, accessibility, and effectiveness of comprehensive real-world cancer datasets, CancerX, a public-private partnership announced by the White House recently conducted a demonstration project, the CancerX Data Sprint. CancerX Data Sprint attempted a novel approach to quickly inform collective efforts of the Center for Medicare and Medicaid Innovation (CMMI), the National Cancer Institute (NCI), the US Food and Drug Administration (FDA), and the Office of the National Coordinator for Health Information Technology (ONC) to advance cancer-related data standards. Specifically, at the intersection of CMMI’s Enhancing Oncology Model (EOM) and the development of ONC’s United States Core Data for Interoperability (USCDI+) – Oncology extension, CancerX leveraged its unique model and broad membership to report novel insights to advance data-driven innovations in oncology research, care, and policy. Methods: From Sept to Dec 2023, the Data Sprint convened 150+ member organizations from industry and government partners to 1) Identify the high-value research questions that could be asked about the standardized real-world data (RWD) generated through EOM 2) Supplement the existing data elements with new ones to extend and enhance the ability to conduct scientific, clinical, and research inquiries with comprehensive datasets. The CancerX community opined via surveys, written feedback, and live workshops to identify key data elements, discuss their clinical value and technical feasibility, and consider their use in real-world settings as part of the comprehensive datasets. Results: Building on the current EOM clinical data elements, we identified and reported 15 new clinical data elements for considerations with high clinical utility and ease of technical abstraction. This comprehensive RWD encompasses a diverse range of patient demographics, clinical details, treatment histories, and outcomes, creating a more accurate and inclusive portrayal of cancer treatment effectiveness and patient journeys. This depth of information is crucial for optimizing the personalization of treatment pathways, conducting impact assessments, and addressing healthcare disparities. Essentially, the new datasets serve as a valuable repository of insights, driving advancements in cancer research, treatment and elevating care quality. Conclusions: CancerX remains committed to supporting federal data initiatives like USCDI+ Cancer standards development and others by providing recommendations for essential data elements implementation to enhance clinical utility, technical feasibility, and exchange of standardized cancer data. By adopting a unique approach and assembling an interdisciplinary group, we can ensure that data standardization efforts prioritize high-utility data elements, ultimately maximizing benefits for our patients.

e23291 Background: Hematologic cancers (HCs) in Southeast Asia (SEA), a diverse population of over 680 million, are still understudied. Data from the 2020 Global Cancer Observatory (GCO) was used to estimate the incidence and mortality of HCs in the region to provide direction for effective disease control and improve population outcomes. Methods: The International Agency for Research on Cancer’s publicly available GCO data aggregates global cancer incidence and mortality. We report cumulative incidence rate (CIR) and cumulative mortality rate (CMR) defined per 100,000 people, and weighted average age-standardized incidence rate (ASIR) and age-standardized mortality rate (ASMR) in 2020. Data for Hodgkin Lymphoma (HL), Non-Hodgkin's Lymphoma (NHL), Leukemia, and Multiple Myeloma (MM) in the world, in SEA, and in the 11 individual SEA countries are presented. Results: The table presents CIR, ASIR, CMR, and ASMR of hematologic cancers in SEA compared to overall global data. CIR, ASIR, CMR, and ASMR were higher for males than females in SEA. For NHL, CIR was highest in Singapore (18.8), Thailand (10.2), and Brunei (9.6) and lowest in Myanmar & Cambodia (3.6), and Timor-Leste (2.7). ASIR trends were parallel albeit differences were smaller. CMR was highest in Singapore (6.2) and Thailand (5.9) and lowest in Timor-Leste (1.5). ASMR was highest in Brunei (4.5) and lowest in Timor-Leste (2.0). For leukemia, CIR was highest in Singapore (11.1) and lowest in Myanmar (3.1) and Timor-Leste (2.6); ASIR was highest in Singapore (8.9) and lowest in Myanmar (3.2) and Timor-Leste (2.9). CMR was highest in Singapore (5.2) and lowest in Myanmar (2.6) and Timor-Leste (2.3). ASMR was highest in Lao PDR (4.7) and Vietnam (4.5), and lowest in Singapore (3.1) and Timor-Leste (2.9). For MM, CIR was highest in Singapore (4.1), ASIR was highest in Brunei (2.4) and both are lowest in Myanmar (0.4). CMR was highest in Singapore & Thailand (1.8) and lowest in Myanmar (0.35); ASMR rates were similar. For HL, CIR was highest in Brunei Darussalam (1.8) and Singapore (1.4) and lowest in Myanmar (0.2). ASIR trends were similar. CMR was highest in Vietnam (0.26) and lowest in Singapore (0.1) and Myanmar (0.08). ASMR trends were similar. Conclusions: Despite lower regional average incidence and mortality, significant intra-regional variations exist reflecting disparities in the management of HCs. In addition, while data suggests lower disease burden in SEA, mortality rates are still comparable and in some cases worse than the global average. More work is needed to investigate HC epidemiology in SEA to inform cancer control in the region and improve its blood cancer outcomes. [Table: see text]

Published: June 2024

e23297 Background: Risks and benefits associated with use of anticoagulants (ACs) in cancer patients should be carefully assessed due to an increased risk of both thrombotic recurrences and bleeding events. Vitamin K antagonists (AVK) have been the most used ACs for patients with atrial fibrillation and venous thromboembolism for many years. Low molecular weight heparins (LMWH) and direct oral anticoagulants (DOACs) are preferred over AVK for cancer associated thrombosis. To better define the current scenario for ACs in cancer patients we propose to use market research data to describe treatment patterns in Europe and Asia. Methods: This study was conducted using Oncology Dynamics, an online secondary market research survey collecting anonymized patient data, from a representative panel of physicians. Data for 11,568 drug-treated oncology patients (p) (9,178 Europe p; 2,390 Asia p) with active cancer and anticoagulant therapies, collected between Q3 2021 and Q3 2023, from 5 European (France, Spain, Germany, Italy, & UK) and 3 Asian countries (China, Japan, & S. Korea), were analyzed. Patients with Genitourinary (GU) tumors were 36%, Lung 19%, Gastrointestinal (GI) 18%, Hepatobiliary/pancreas 12%, Gynecologic (Gyn) 12%, and Melanoma and Brain < 5%. Results: 94% p were aged > 50 years and 49% > 70 years. 64% p were male and 36% female. 67% p showed advanced/metastatic stage vs 33% local/locally advanced stage. Globally, DOACs use was 55%, LMWH 35%, and AVK < 10%; DOACs were the preferred ACs in Europe (64% p) and LMWH in Asia (59% p). Prescription of AVKs in Asia population was higher (17% p) compared with Europe (7% p). Difference in use of ACs by tumor type in European countries in favor of DOACs vs LMWH was noticeable in GU (75% p vs 13% p), GI (61% vs 34%) and Melanoma (71% vs 22%). In Asia population, predominance of LMWH vs DOACs was observable in Gyn (86% p vs 5% p), GI (57% vs 24%) and Hepatobiliary/pancreas (56% vs 35%). AVK were administered in 53% of GU Asia p and DOACs in 31%. Overall, bleeding was more frequently associated with AVK (32% p), compared to DOACs (15% p) and LMWH (9% p). Conclusions: This research highlights the differences in ACs prescription in oncology patients between Asia and Europe, with a preference for LMWH in former and DOACs in the latter. DOACs are the most common ACs prescribed overall, while AVK, associated with higher incidence of bleeding, are used in a small population. A more comprehensive analysis of the included variables will be shared.
Evaluating reflexive NGS and testing rates in community oncology.
Authors: Cripps Amy Patricia , Prakash Akshay 
Published: June 2024

e23302 Background: In oncology, NGS allows for the identification of DNA sequence variations within a cancer. The goal of testing is to identify/define therapeutic targets & improve patient outcomes, employing specific therapies directed at those targets. In breast cancer, reflex tumor testing (ER/PR/Her2neu) has been performed for > 20 yrs. In CRC, as published by ASCO, guideline-adherent biomarker testing rates for RAS, BRAF, & MSI/MMR-d were 41%, 43%, and 51%, respectively1. In lung cancer, recent data has shown overall testing rates minimally better at 58%2. Methods: The study was conducted on historical data of lung, colorectal, and breast cancer patients seen in Verdi community oncology clinics between 4/1/2022-7/31/2023. Clinical & social health data were collected & abstracted from patient medical history (Doctor’s notes, Pathology studies, NGS results). The database contains demographic & clinical data features for each patient. Results: 153 lung cancer patients were identified, median age 71(44 – 96). 82 F, 71 M. 85% of patients were smokers (130 smokers, 22 non-smokers, 1 unknown). Self-identified race: Asian 1, Black 22, white 106, 24 patients declined to identify. 61.9% (65) of later stage (≥IIB) patients had NGS testing. Of 258 colon/rectal cancer patients (anal cancer was excluded), median age 67(29-96), 122 M,146 F. Self-identified race: Asian 3, Black 26, 181 white, 34 patients declined to identify, 14 were unknown. Overall, 34.5% (89) of patients had NGS testing, and 76.2% (34) of Stage IV patients. There were 511 breast cancer patients, median age 63(25-85), 506 F, 5 M. Self-identified race: Asian/HPI 2, Black 137, white 299, 56 patients declined to identify, 17 were unknown. 100% had NGS, with minimum testing of ER/PR/Her2neu status. In the lung & colorectal patients, statistically significant differences in rates of testing were seen in males (p < 0.0001), older age (p < 0.0001), and non-whites (p = 0.002). Conclusions: Testing at Verdi clinics were higher than reported testing. We propose that to improve testing rates, NGS should be reflexively ordered in other tumor types, as is the standard of care in breast cancer. This would eliminate many issues, including waiting time patients must undergo when testing is not ordered until the patient is seen by the medical oncologist. Proactive testing allows potential targeted treatments to be delivered in real-time and thus improve patient outcomes. 1Genomic Profiling for KRAS, NRAS, BRAF, Microsatellite Instability, and Mismatch Repair Deficiency Among Patients With Metastatic Colon Cancer.

e23303 Background: Breast cancer is the most prevalent cancer and second leading cause of cancer-related mortality among Canadian women. Most of cases belong to the HR+/HER2- subtype, representing approximately two-thirds of all instances. Treatment for this subtype encompasses a multifaceted approach with a curative intent. This real-world evidence study aims to comprehensively analyze the clinical outcomes of Canadian patients diagnosed with early-stage HR+/HER2- breast cancer, focusing on recurrence rates after initiation of adjuvant endocrine therapy to identify opportunities for enhancing patient care. Methods: This is a retrospective, longitudinal cohort study involving 541 patients enrolled in the pan-Canadian cancer patient registry PMT (Personalize My Treatment), with newly diagnosed or recurrent stage II or III HR+/HER2- breast cancer between January 1st, 1996, and May 31st, 2022. We evaluated disease recurrence rates, time to recurrence, and overall survival (OS). Furthermore, the study explored duration of endocrine therapy (ET) in the adjuvant setting. Results: 409 patients received adjuvant ET representing 75.6% of the total cohort, emphasizing the role of ET as standard of care for adjuvant treatment in this patient population. The median duration of adjuvant ET was 4.5 years. In the overall adjuvant patient population, recurrence rates progressively increased over time from 13.2% after 2 years, 21.4% after 3 years, 30.3% after 5 years, and peaking at 58.4% after 10 years. Median time to recurrence for the overall patient population on ET was 7.76 years. OS rate for patients on ET was 94.6% at 5 years and 78.3% at 10 years. Conclusions: This study marks a pioneering real-world analysis utilizing pan-Canadian EHR data, demonstrating increasing recurrence rates over time in HR+/HER2- early breast cancer. It highlights the high unmet need in stage II and stage III breast cancer, with 1 patient out of 3 recurring after 5 years, and more than half recurring after 10 years despites adjuvant treatment with ET alone. This indicates the need for more efficacious and tolerable treatment options to reduce short- and long-term recurrence and to prolong survival, not only in the higher risk patient population, but in the overall HR+/HER2- breast cancer patients at increased risk of recurrence.

Published: June 2024

e23306 Background: Randomized clinical trials are the “gold standard”, but expensive and not always practice changing. Umbilical cord blood (UCB) and haploidentical (haplo) are donor sources for hematopoietic cell transplant (HCT) patients who do not have a fully matched donor. The Blood and Marrow Transplant Clinical Trials Network (CTN) 1101 trial (2012-2018) compared outcomes of double UCB and haplo bone marrow (BM) transplantation. The trial showed a lower two-year overall survival after UCB compared to haplo (46% vs 57%, p = 0.04). Here, we quantified the change in graft selection in clinical practice in the U.S. after publication of the trial’s primary results. Methods: 11,190 U.S. HCT recipients 18-70 years of age who received either UCB (single or double units) or haplo transplants (BM or peripheral blood stem cells), for leukemias, lymphomas, myelodysplastic syndrome, myeloproliferative neoplasms, who reported to the Center for International Blood and Marrow Transplant Research database, were analyzed. Graft utilization was analyzed in 3 time periods: 2010-2012 (pre-study), 2013-2018 (during study), and 2019-2022 (post-study), using Chi-square test and multivariable logistic regression. Results: Over the 3 time periods, there was a practice change with an increasing proportion of haplo transplants vs UCB (32%, 68% and 91% of transplants, p < 0.001; odds ratio (OR) of 4.67 and 21.38 for during-study and post-study periods, respectively, both with p < 0.001, compared to pre-study period). Males and older patients were more likely to receive haplo (OR = 1.32, p < 0.001, and OR = 1.74, p < 0.001, respectively). Compared to White recipients, Black recipients were more likely to receive haplo (OR = 1.74, p < 0.001), whereas Asian recipients were less likely to receive haplo (OR = 0.75, p = 0.002). Hispanic recipients had a similar likelihood of receiving haplo to White patients (OR = 1.03, p = 0.665). Conclusions: Practice change toward haploidentical graft utilization had begun before the CTN 1101 trial’s publication and continued to increase over time. Black patients were more likely than White patients to receive haplo, and Asian patients were more likely than White patients to receive UCB. Availability of both UCB and haplo as alternative graft sources allowed for HCT for a diverse population. [Table: see text]

Published: June 2024

e23313 Background: Breast cancer incidence in the Philippines is among the highest in Asia - the WHO reported it to be as high as 33,079 in 2022. Data provided by the Philippine Cancer Society and Department of Health Rizal Cancer Registry in 2009 included 1,615 breast cancer patients and noted a significant increase in breast cancer incidence from the year 1980 to 2002 in 7 cities in Metro Manila. This retrospective study aims to describe and analyze clinicopathologic and treatment data of Filipino breast cancer patients in a tertiary hospital. This study represents the largest pooled data in the Philippines on breast cancer demographics. Methods: Patients diagnosed with invasive breast cancer in St. Luke’s Medical Center (SLMC) from 2009 to 2020 were included. Patients diagnosed with other breast histopathologic results [i.e. ductal and lobular carcinoma in situ without invasive component] and double primaries were excluded. The study was approved by the Ethics Review Committee (Reference No.: SL-19157). Results: A total of 5,462 breast cancer patients were included. Majority of the patients were late perimenopausal (50-59 yo, 30.06%), menopausal (60-69 yo, 23.03%), and premenopausal (below 44 yo, 19.28%,) at the time of diagnosis. Patients were diagnosed with stage II (N = 1,816, 47.24%), followed by stage I (N = 943, 24%), and stage III (N = 662, 17%). Sixty four percent (N = 1,498) were node negative while 46% (N = 1,300) were node positive. Among patients with de novo metastasis, 14.6% metastasized to the bone while visceral sites include chest wall (17.4%), lung (16.6%), liver (11.5%) and brain (7.45%). Luminal her2- (48.9%) was the most common clinical subtype followed by non-luminal her2+ (15.6%) and triple negative (6.7%). Definitive surgery was the mainstay of treatment – 94% (N = 4116) underwent modified radical mastectomy (MRM) while 5% (N = 223) underwent breast conserving surgery (BCS). Eight hundred patients (19%) received neoadjuvant treatment (hormonal and/or systemic chemotherapy) while 2,246 patients (54%) received adjuvant treatment. Total number of breast cancer patients who underwent adjuvant radiation was 1,399 (25.6%). Conclusions: Compared to middle-high income countries, data suggests that MRM is the preferred surgical technique over BCS. Majority of patients in the study are luminal her2-. However, only 54% received adjuvant treatment. Another observation is the low rate of neoadjuvant treatment by the study population. Further research on the risk factors or reasons for not receiving treatment as well as the outcomes of these patient cohorts is needed to shed light on these cancer care gaps.
