Background: Women are the fastest growing veteran group in the US and the number of women veterans (WVs) with cancer is rising; however, little is known about this population. Cancer care for WVs is complex and it is essential to understand their unique needs and care coordination challenges to provide evidence-based care. The purpose of this review is to map the quantity, distribution, and characteristics of literature describing cancer and its treatment among WVs., Methods: We searched MEDLINE (via PubMed), Embase (Elsevier), and Web of Science Core Collection (Clarivate) from inception through January, 2024. Publications were eligible that reported gender-specific data on any aspect of cancer care among WVs. Data was abstracted by a single investigator with over-reading., Results: Forty-six reports were included; 44 were observational and 19 had a women-only sample. There were no interventional reports and no qualitative reports had a patient sample. Breast cancer was the most commonly addressed (n = 19). There were six additional reports on sex-specific cancers. Many reports used large VA databases or previous trial data, creating the potential for patient overlap between reports. Among VA-specific areas of interest, only three reports evaluated the potential implications of racial differences and only two included a transgender population. No reports examined the effects of toxic exposures on cancer. Within the NCI Cancer Control Continuum, crosscutting areas were more commonly represented; over half (25) of the reports addressed epidemiology. There were few reports on focus areas and little overlap between focus and crosscutting areas., Discussion: Existing literature provides an inadequate understanding of the population of WVs with cancer. There is scant information regarding the population of WVs with cancer, their care preferences or experiences, or how to best identify and address unmet healthcare needs. It is imperative to expand research to provide evidence-based care for this population., (© 2024.

Background: In recent years the US health-care system has witnessed a substantial increase in telehealth use. Telehealth enhances health-care access and quality and may reduce costs. However, there is a concern that the shift from in-person to telehealth care delivery may differentially improve cancer care access and quality in certain clinical settings and for specific patient populations while potentially exacerbating disparities in care for others. Our National Cancer Institute-funded center, called Telehealth Research and Innovation for Veterans with Cancer (THRIVE), is focused on health equity for telehealth-delivered cancer care. We seek to understand how social determinants of telehealth-particularly race and ethnicity, poverty, and rurality-affect the use of telehealth., Methods: THRIVE draws from the Health Disparities Research Framework and the Consolidated Framework for Implementation Research. THRIVE consists of multiple cores that work synergistically to assess and understand health equity for telehealth-delivered cancer care. These include the Administrative Core, Research and Methods Core, Clinical Practice Network, and Pragmatic Trial., Results: As of October 2023, we identified and trained 5 THRIVE scholars, who are junior faculty beginning a research career. We have reviewed 20 potential pilot studies, funding 6. Additionally, in communication with our funders and advisory boards, we have adjusted our study design and analytic approach, ensuring feasibility while addressing our operational partners' needs., Conclusions: THRIVE has several key strengths. First, the Veterans Health Administration's health-care system is large and diverse regarding health-care setting type and patient population. Second, we have access to longitudinal data, predating the COVID-19 pandemic, about telehealth use. Finally, equitable access to high-quality care for all veterans is a major tenet of the Veterans Health Administration health-care mission. As a result of these advantages, THRIVE can focus on isolating and evaluating the impact of social determinants of telehealth on equity in cancer care., (© The Author(s) 2024.

The Veterans Health Administration (VHA) has pioneered teleoncology to address access challenges faced by Veterans requiring cancer care. This ASCO Educational Book highlights the development of teleoncology programs within the VHA: the local VA Pittsburgh Healthcare System (VAPHS) Virtual Cancer Care Center, the National TeleOncology Program (NTO), and the regional Clinical Resource Hub (CRH) Oncology Program. These initiatives provide oncology care using a hub-and-spoke model, which centralizes expertise at hub sites and reaches Veterans at distant spoke sites through synchronous and asynchronous care. The deployment of these teleoncology programs has resulted in significant benefits, such as decreased travel for Veterans, high levels of patient satisfaction, and improved access to specialized treatments. Despite these advancements, disparities in teleoncology utilization and access to clinical trials persist. This educational manuscript highlights the successes and challenges of tele-oncology within the VHA, underscoring the critical role of telehealth in overcoming access barriers.

Purpose: Telegenetics services can expand access to guideline-recommended cancer genetic testing. However, access is often not distributed equitably to all races and ethnicities. We evaluated the impact of an on-site nurse-led cancer genetics service in a diverse Veterans Affairs Medical Center (VAMC) oncology clinic on likelihood of germline testing (GT) completion., Methods: We conducted an observational retrospective cohort study of patients who were referred for cancer genetics services at the Philadelphia VAMC between October 1, 2020, and February 28, 2022. We evaluated the association between genetics service (on-site v telegenetics) and likelihood of GT completion in a subcohort of new consults, excluding patients with prior consults and those referred for known history of germline mutations., Results: A total of 238 Veterans, including 108 (45%) seen on site, were identified for cancer genetics services during the study period, with the majority referred for a personal (65%) or family (26%) history of cancer. In the subcohort of new consults, 121 Veterans (54% self-identified race/ethnicity [SIRE]-Black), including 60 (50%) seen on site, were included in the analysis of germline genetic testing completion. In a univariate analysis, patients who were seen by the on-site genetics service had 3.2-fold higher likelihood of completing GT (relative risk, 3.22; 95% CI, 1.89 to 5.48) compared with the telegenetics service. In multivariable regression analysis, the on-site genetics service was associated with higher likelihood of GT completion, but this association was only statistically significant in SIRE-Black compared with SIRE-White Veterans (adjusted RR, 4.78; 95% CI, 1.53 to 14.96; P < .001; P -interaction of race × genetics service = .016)., Conclusion: An on-site nurse-led cancer genetics service embedded in a VAMC Oncology practice was associated with higher likelihood of germline genetic testing completion than a telegenetics service among self-identified Black Veterans.

Black Veterans have higher a incidence of localized and metastatic prostate cancer compared to White Veterans yet are underrepresented in reports of frequencies of somatic and germline alterations. This retrospective analysis of somatic and putative germline alterations was conducted in a large cohort of Veterans with prostate cancer (N = 835 Black, 1613 White) who underwent next generation sequencing through the VA Precision Oncology Program, which facilitates molecular testing for Veterans with metastatic cancer. No differences were observed in gene alterations for FDA approved targetable therapies (13.5% in Black Veterans vs. 15.5% in White Veterans, P = .21), nor in any potentially actionable alterations (25.5% vs. 28.7%, P =.1). Black Veterans had higher rates of BRAF (5.5% vs. 2.6%, P < .001) alterations, White Veterans TMPRSS2 fusions (27.2% vs. 11.7%, P < .0001). Putative germline alteration rates were higher in White Veterans (12.0% vs. 6.1%, P < .0001). Racial disparities in outcome are unlikely attributable to acquired somatic alterations in actionable pathways., (Published by Oxford University Press 2023.)

Purpose: As the largest integrated health care system in the United States, the Veterans Health Administration (VA) is a leader in telehealth-delivered care. All 10 million Veterans cared for within the VA are eligible for telehealth. The VA cares for approximately 46,000 Veteran patients with newly diagnosed cancer and an estimated 400,000 prevalent cases annually. With nearly 38% of VA health care system users residing in rural areas and only 44% of rural counties having an oncologist, many Veterans lack local access to specialized cancer services., Methods: We describe the VA's National TeleOncology (NTO) Service. NTO was established to provide Veterans with the opportunity for specialized treatment regardless of geographical location. Designed as a hub-and-spoke model, VA oncologists from across the country can provide care to patients at spoke sites. Spoke sites are smaller and rural VA medical centers that are less able to independently provide the full range of services available at larger facilities. In addition to smaller rural spoke sites, NTO also provides subspecialized oncology care to Veterans located in larger VA medical facilities that do not have subspecialties available or that have limited capacity., Results: As of fiscal year 2021, 23 clinics are served by or engaged in planning for delivery of NTO and there are 24 physicians providing care through the NTO virtual hub. Most NTO physicians continue to provide patient care in separate traditional in-person clinics. Approximately 4,300 unique Veterans have used NTO services. Approximately half (52%) of Veterans using NTO lived in rural areas. Most of these Veterans had more than one remote visit through NTO., Conclusion: NTO is a state-of-the-art model that has the potential to revolutionize the way cancer care is delivered, which should improve the experience of Veterans receiving cancer care.

Purpose: Neurotrophic tyrosine receptor kinase 1-3 ( NTRK1-3 ) gene fusions are found in a broad range of tumor types. Clinical trials demonstrated high response rates to tropomyosin receptor kinase (TRK) inhibitors in NTRK fusion-positive cancers, but few reports have described real-world experience with these targeted agents. We evaluated the prevalence of NTRK fusions and the outcomes with TRK inhibitor therapy in a real-world population of patients in the Veterans Health Administration., Methods: Patients with NTRK fusions or rearrangements were identified from the Veterans Affairs (VA) National Precision Oncology Program (NPOP), and patients who were prescribed TRK inhibitors were identified from the Corporate Data Warehouse. Baseline data and clinical outcomes were obtained by retrospective review of medical records., Results: A total of 33 patients with NTRK fusions or rearrangements were identified, including 25 patients comprising 0.12% of all patients with solid tumors sequenced through VA NPOP. Twelve patients with NTRK fusions or rearrangements were treated with TRK inhibitors, none of whom had objective responses. Eight patients experienced toxicities leading to drug interruption, dose reduction, or discontinuation., Conclusion: In this retrospective study of VA patients, NTRK fusions and rearrangements were less common than in previous studies, and objective responses to TRK inhibitors were not observed. Real-world experience with TRK inhibitors differs markedly from clinical trial findings, possibly due to differences in patient demographics, tumor types, and sequencing methods. Our findings highlight the need to study TRK inhibitors in the real-world setting and in populations underrepresented in clinical trials.

Background: Cancer diagnoses are associated with an increased risk for suicide. The aim of this study was to evaluate this association among Veterans receiving Veterans Health Administration (VHA) care, a population that has an especially high suicide risk., Methods: Among 4,926,373 Veterans with VHA use in 2011 and in 2012 or 2013, and without VHA cancer diagnoses in 2011, we assessed suicide risk following incident cancer diagnoses. Risk time was from initial VHA use in 2012-2013 to 12/31/2018 or death, whichever came first. Cox proportional hazards regression models evaluated associations between new cancer diagnoses and suicide risk, adjusting for age, sex, VHA regional network, and mental health comorbidities. Suicide rates were calculated among Veterans with new cancer diagnoses through 84 months following diagnosis., Results: A new cancer diagnosis corresponded to a 47% higher suicide risk (Adjusted Hazard Ratio [aHR] = 1.47, 95% CI: 1.33-1.63). The cancer subtype associated with the highest suicide risk was esophageal cancer (aHR = 6.01, 95% CI: 3.73-9.68), and other significant subtypes included head and neck (aHR = 3.55, 95% CI: 2.74-4.62) and lung cancer (aHR = 2.35, 95% CI: 1.85-3.00). Cancer stages 3 (aHR = 2.36, 95% CI: 1.80-3.11) and 4 (aHR = 3.53, 95% CI: 2.81-4.43) at diagnosis were positively associated with suicide risk. Suicide rates were highest within 3 months following diagnosis and remained elevated in the 3-6- and 6-12-month periods following diagnosis., Conclusion: Among Veteran VHA users, suicide risk was elevated following new cancer diagnoses. Risk was particularly high in the first 3 months. Additional screening and suicide prevention efforts may be warranted for VHA Veterans newly diagnosed with cancer., (Published 2022.

Background: Patients with advanced head and neck squamous cell carcinoma (HNSCC) associated with human papillomavirus (HPV) demonstrate favorable clinical outcomes compared to patients bearing HPV-negative HNSCC. We sought to characterize the association between HPV status and mutational profiles among patients served by the Veterans Health Administration (VHA)., Methods: We performed a retrospective analysis of all Veterans with primary HNSCC tumors who underwent next-generation sequencing (NGS) through the VHA's National Precision Oncology Program between July 2016 and February 2019. HPV status was determined by clinical pathology reports of p16 immunohistochemical staining; gene variant pathogenicity was classified using OncoKB, an online precision oncology knowledge database, and mutation frequencies were compared using Fisher's exact test., Results: A total of 79 patients met inclusion criteria, of which 48 (60.8%) had p16-positive tumors. Patients with p16-negative HNSCC were more likely to have mutations in TP53 (p < 0.0001), and a trend towards increased mutation frequency was observed within NOTCH1 (p = 0.032) and within the composite CDK/Rb pathway (p = 0.065). Mutations in KRAS, NRAS, HRAS, and FBXW7 were exclusively identified within p16-positive tumors, and a trend towards increased frequency was observed within the PI3K pathway (p = 0.051). No difference in overall mutational burden was observed between the two groups., Conclusions: In accordance with the previous studies, no clear molecular basis for improved prognosis among patients harboring HPV-positive disease has been elucidated. Though no targeted therapies are approved based upon HPV-status, current efforts to trial PI3K inhibitors and mTOR inhibitors across patients with HPV-positive disease bear genomic rationale based upon the current findings., (© 2022.

Purpose: There are growing efforts to integrate patient-reported outcome (PRO) data into electronic health records (EHRs) to bring together disparate sources of patient information and improve medical care. PRO measures can be used to assess cancer symptom presence and severity. Integrating PRO tools in EHRs can alert providers to address symptoms, which is an essential component of comprehensive oncology care., Methods: We modified a PRO used to measure cancer and end-of-life symptoms, the Edmonton Symptom Assessment System to create the Veteran Symptom Assessment System (VSAS). VSAS was implemented as an integrated PRO as part of the Veterans Administration EHR system and was used at hematology-oncology clinics in Veteran Administration (VA) medical centers in the Southeast., Results: From 2013 to 2014, VSAS was introduced, underwent usability testing and modifications, and was finally implemented in the EHR. Between 2015 and 2019, VSAS was administered 43,883 times in 9,058 patients. Eighty-nine percent of Veterans were male, 11% were female, 52% identified as non-Hispanic White, and 43% identified as African American. Fatigue, shortness of breath with exertion, and pain were most frequently reported initially (68%, 48%, and 45%, respectively) and were most frequently rated as severe (27%, 16%, and 17%, respectively). In patients diagnosed with stage IV cancer, higher symptom burden was significantly associated with shorter overall survival. The majority of Veterans with longitudinal measurements experienced improvement in symptoms, most frequently in severe symptoms., Conclusion: To our knowledge, this is the first large-scale implementation of a PRO system, integrated in the VA EHR, in ambulatory patients with cancer and blood disorders. The integration of VSAS within the VA EHR is a significant demonstration and a necessary requirement for current and future systemic initiatives in cancer symptom management., Competing Interests: Daphne R.

Purpose: Next-generation sequencing (NGS) gene panels are frequently completed for patients with advanced non-small-cell lung cancer (NSCLC). Patients with highly actionable gene variants have improved outcomes and reduced toxicities with the use of corresponding targeted agents. We sought to identify barriers to targeted agent use within the Veterans Health Affairs' National Precision Oncology Program (NPOP)., Methods: A retrospective evaluation of patients with NSCLC who underwent NGS multigene panels through NPOP between July 2015 and February 2019 was conducted. Patients who were assigned level 1 or 2A evidence for oncogenic gene variants by an artificial intelligence offering (IBM Watson for Genomics [WfG]) and NPOP staff were selected. Antineoplastic drug prescriptions and provider notes were reviewed. Reasons for withholding targeted treatments were categorized., Results: Of 1,749 patients with NSCLC who successfully underwent NGS gene panel testing, 112 (6.4%) patients were assigned level 1 and/or 2A evidence for available targeted treatments by WfG and NPOP staff. All highly actionable gene variants were within ALK , BRAF , EGFR , ERBB2 , MET , RET , and ROS1 . Of these, 36 (32.1%) patients were not prescribed targeted agents. The three most common reasons were (1) patient did not carry a diagnosis of metastatic disease (33.3%), (2) treating provider did not comment on the NGS results (25.0%), and (3) provider felt that patient could not tolerate therapy (19.4%). No patients were denied access to level 1 or 2A targeted drugs because of rejection of a nonformulary drug request., Conclusion: A substantial minority of patients with NSCLC bearing highly actionable gene variants are not prescribed targeted agents. Further provider- and pathologist-directed educational efforts and implementation of health informatics systems to provide real-time decision support for test ordering and interpretation are needed., Competing Interests: Vishal VashisthaEmployment: UnitedHealthcare (I)Research Funding: IBM Watson HealthOther Relationship: IBMUncompensated Relationships: IBM Watson Health Pradeep J.

Background: Transportation barriers limit access to cancer care services and contribute to suboptimal clinical outcomes. Our objectives were to describe the frequency of Veterans reporting and the factors associated with transportation barriers to or from colorectal cancer (CRC) care visits., Methods: Between November 2015 and September 2016, Veterans with incident stage I, II, or III CRC completed a mailed survey to assess perceived barriers to recommended care. Participants who reported difficulty with transportation to or from CRC care appointments were categorized as experiencing transportation barriers. We assessed pairwise correlations between transportation barriers, transportation-related factors (e.g., mode of travel), and chaotic lifestyle (e.g., predictability of schedules), and used logistic regression to examine the association between the reporting of transportation difficulties, distance traveled to the nearest Veterans Affairs (VA) facility, and life chaos., Results: Of the 115 Veterans included in this analysis, 18% reported experiencing transportation barriers. Distance to the VA was not strongly correlated with the reporting of transportation barriers (Spearman's ρ = 0.12, p = 0.19), but chaotic lifestyle was both positively and significantly correlated with experiencing transportation barriers (Spearman's ρ = 0.22, p = 0.02). Results from the logistic regression model modestly supported the findings from the pairwise correlations, but were not statistically significant., Conclusions: Transportation is an important barrier to or from CRC care visits, especially among Veterans who experience greater life chaos. Identifying Veterans who experience chaotic lifestyles would allow for timely engagement in behavioral interventions (e.g., organizational skills training) and with support services (e.g., patient navigation).

Background: The Veterans Affairs (VA) healthcare system is a high-volume provider of cancer care. Women are the fastest growing patient population using VA healthcare services. Quantifying the types of cancers diagnosed among women in the VA is a critical step toward identifying needed healthcare resources for women Veterans with cancer., Materials and Methods: We obtained data from the VA Central Cancer Registry for cancers newly diagnosed in calendar year 2010. Our analysis was limited to women diagnosed with invasive cancers (e.g., stages I-IV) between January 1, 2010, and December 31, 2010, in the VA healthcare system. We evaluated frequency distributions of incident cancer diagnoses by primary anatomical site, race, and geographic region. For commonly occurring cancers, we reported distribution by stage., Results: We identified 1,330 women diagnosed with invasive cancer in the VA healthcare system in 2010. The most commonly diagnosed cancer among women Veterans was breast (30%), followed by cancers of the respiratory (16%), gastrointestinal (12%), and gynecological systems (12%). The most commonly diagnosed cancers were similar for white and minority women, except white women were significantly more likely to be diagnosed with respiratory cancers (p < 0.01) and minority women were significantly more likely to be diagnosed with gastrointestinal cancers (p = 0.03)., Conclusions: Understanding cancer incidence among women Veterans is important for healthcare resource planning. While cancer incidence among women using the VA healthcare system is similar to U.S civilian women, the geographic dispersion and small incidence relative to male cancers raise challenges for high quality, well-coordinated cancer care within the VA.

Introduction: Ensuring guideline-concordant cancer care is a Department of Veterans Affairs (VA) priority, especially as the number of breast cancer patients at VA medical centers (VAMCs) grows. We assessed the utilization and clinical impact of the 21-gene Recurrence Score test, which predicts 10-year risk of breast cancer recurrence and the likelihood of chemotherapy benefit, on veterans newly diagnosed with breast cancer., Patients and Methods: We conducted a retrospective cohort study using 2011-2012 VA Central Cancer Registry, chart review, and laboratory test data. Independent variables assessed included patient and site-of-care characteristics. The outcome of interest was whether newly diagnosed, eligible (node negative, hormone-receptor positive, human epidermal growth factor receptor 2 [HER2] negative) veterans underwent the 21-gene test. We performed descriptive statistics on all patients and multivariate logistic regression to determine associations. We correlated treatments received with test results., Results: Among 328 eligible veterans, 82 (25%) had the 21-gene test; 100 eligible veterans (30%) sought care at a VAMC where no tests were ordered. Receiving care at a VAMC that had women's health services (odds ratio [OR], 1.84, 95% confidence interval [CI], 1.05-3.22) and having tumor characteristics meeting the National Comprehensive Cancer Network 2010 test criteria (OR, 3.06, 95% CI, 1.69-5.57) were positive predictors of testing; increasing age (OR, 0.93, 95% CI, 0.91-0.96 per year) and fee-based care (OR, 0.46, 95% CI, 0.26-0.82) were negative predictors. The majority of tested patients received guideline-concordant care., Conclusion: Site of care and tumor characteristics were important predictors of test uptake. Facilitating delivery of guideline-concordant cancer care requires improved laboratory informatics and clinical decision support., (Published by Elsevier Inc.)

Background: Colorectal cancer (CRC) is the third most commonly diagnosed cancer in the US. CRC survivors may have complex healthcare needs requiring care from both specialists and primary care. Our objective was to understand how CRC survivors perceive their survivorship care, especially management of their cardiovascular-related chronic diseases., Methods: We identified patients diagnosed with non-metastatic CRC between 10/1/2007 and 12/31/2015 at Veterans Affairs Medical Centers in North Carolina or Virginia. In 2016, we conducted telephone-based, semi-structured interviews to assess survivors' experiences with cancer survivorship and changes in health priorities. Interviews were conducted until thematic saturation was reached. Interviews were audio-recorded, transcribed, and coded., Results: The 25 participants were, on average, 64 years old and approximately 4 years post-CRC diagnosis at the time of interview; most were white (60%), male (92%), and diagnosed with colon cancer (64%) as opposed to rectal cancer. CRC survivors reported: (1) a shift in focus from surviving cancer to reducing cardiovascular disease risk (e.g., by managing weight); (2) challenges with taking medications for CVD-related conditions; (3) new recognition of the importance of engaging with primary care providers., Conclusions: Experiences with cancer shapes how survivors view their health. Management of cardiovascular-related chronic disease is important to veteran CRC survivors. There is a need to deliver cardiovascular disease risk reduction programs tailored for CRC survivors.

Introduction: Nearly 50,000 incident cancer cases are reported in Veterans Affairs (VA) Central Cancer Registry (VACCR) annually. This article provides an updated report of cancer incidence recorded in VACCR., Materials and Methods: Data were obtained from VACCR for incident cancers diagnosed in the VA health care system, focusing on 2010 data. Cancer incidence among VA patients is described by anatomical site, sex, race, stage, and geographic location, and was compared to the general U.S. cancer population., Results: In 2010, among 46,170 invasive cancers, 97% were diagnosed among men. Approximately 80% of newly diagnosed patients were white, 19% black, and less than 2% were other minority races. Median age at diagnosis was 65 years. The three most frequently diagnosed cancers among VA were prostate (29%), lung/bronchus (18%), and colon/rectum (8%). Melanoma and kidney/renal pelvis tied for fourth (4%), and urinary bladder tied for sixth with liver and intrahepatic bile duct (3.4%). Approximately 23% of prostate, 21% of lung/bronchus, and 31% of colon/rectum cancers were diagnosed with Stage I disease. The overall invasive cancer incidence rate among VA users was 505.8 per 100,000 person-years., Conclusions: Although the composition of the VA population is shifting and includes a larger number of women, registry data indicate that incident cancers in VA in 2010 were most similar to those observed among U.S. men. Consistent reporting of VACCR data is important to provide accurate estimates of VA cancer incidence. This information can be used to plan efforts to improve quality of cancer care and access to services., (Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.)

Introduction: We examined mutational testing of the epidermal growth factor gene (EGFR) and erlotinib treatment among veterans diagnosed with non-small-cell lung cancer in the United States Department of Veterans Affairs (VA). Our objectives were to identify the prevalence of clinically actionable EGFR mutations, to determine whether testing and treatment were guideline concordant, to evaluate the impact of testing and treatment on survival, and to estimate the rate of testing., Patients and Methods: Test results were linked to electronic health records from VA Corporate Data Warehouse and the VA Central Cancer Registry. We analyzed patient demographic and clinical characteristics, prevalence of EGFR mutations, and timing of EGFR mutational testing and erlotinib treatment based on pharmacy records. Overall survival was assessed by Kaplan-Meier analysis., Results: Among 973 patients tested at 70 VA medical centers between 2011 and 2013, 64 (7%) had sensitizing EGFR mutations, 694 (71%) were EGFR wild type, and 168 (17%) had clinically insignificant polymorphisms or variants of unknown significance. Results were not documented in 47 tests (5%). Erlotinib administration was in agreement with test results in 843 cases (87%)., Conclusion: Veterans have a much lower rate of sensitizing EGFR mutations than the reported average of 10% to 15%, which correlates with a high rate of smoking among veterans. This may partially explain clinicians' reluctance to prescribe EGFR testing, which results in underutilization. Although test results appear to have influenced erlotinib treatment decisions, we documented a substantial number of cases where treatment was not applied in accordance with clinical guidelines, potentially resulting in worse outcomes and unnecessary cost., (Published by Elsevier Inc.)

Background: Colorectal cancer (CRC) is a common and potentially deadly disease. Although the United States has robust cancer data reporting, information from the Department of Veterans Affairs (VA) healthcare system has often been underrepresented in national cancer data sources. We describe veterans with incident CRC in terms of their patient and tumor characteristics and mortality., Patients and Methods: Patients diagnosed or treated with CRC at any VA institution in the fiscal years 2009 to 2012 were identified using 3 data sources: (1) VA Central Cancer Registry (VACCR); (2) VA Corporate Data Warehouse; and (3) VA Reports and Measures Portal. The CRC frequencies within the VA population and survival curves were examined descriptively and compared with the national projections using Surveillance, Epidemiology, and End Results program data., Results: A total of 12,551 veterans with CRC were included in the present analysis. The median age at diagnosis was 65.5 years. Approximately 97% (n = 12,229) of the CRC cases were diagnosed among men. Approximately 44% (n = 5517) of the patients were diagnosed with localized disease. The 3-year survival rate was associated with age (P < .01) and stage (P < .01) at diagnosis. We identified a possible decrease in VA CRC incidence over time., Conclusion: Although the VA CRC patient population was heavily skewed toward the male gender, the patient and tumor characteristics were similar between the incident CRC cases reported by the VACCR and those reported to the Surveillance, Epidemiology, and End Results program. This suggests that research findings resulting from the VACCR might have applicability beyond the VA healthcare system setting., Competing Interests: The authors report no conflicts of interest in this work.

Purpose: A growing set of quality measures is being implemented to evaluate all components of cancer care, from diagnosis through the end of life. We investigated the Quality Oncology Practice Initiative (QOPI) quality measures portfolio. Additionally, we explored the effect of quality measure type on conformance., Methods: We performed QOPI data collections twice per year from fall 2007 through fall 2010 and spring 2012, using chart review of the Durham Veterans Administration outpatient oncology clinic. We categorized QOPI measures as nontreatment-related supportive care (NTSC), treatment-related supportive care (TSC), diagnostic, or therapeutic. Descriptive statistics and χ(2) were used to compare longitudinal conformance., Results: The majority of QOPI measures in spring 2012 assess processes of chemotherapy treatment (therapeutic, 54.3%; TSC, 8.7%) or diagnostic modalities (19.6%). Measures targeting NTSC are few (17.4%) but increased from three measures in fall 2007 to eight measures in spring 2012. During those 5 years, average conformance to NTSC, TSC, diagnostic, and therapeutic measures was 71.4%, 86.1%, 89.3%, and 75.4%, respectively (P < .001). Within the NTSC measures, emotional well-being and constipation assessment were least documented (41.0% and 46.3%, respectively). In spring 2012, NTSC measure conformance (75.8%) remained significantly lower than diagnostic measure conformance (91.5%; P < .001)., Conclusion: Most QOPI quality measures assess diagnosis or treatment processes of care and not supportive care. Aggregate conformance to the NTSC measures was lower than that of other categories. The differential conformance demonstrates the necessity of standardized documentation methods and quality improvement efforts that remain commensurate with the increasing portfolio of supportive care measures.

Purpose: It is unclear why racial differences exist in the frequency of surgery for lung cancer treatment. Comorbidity is an important consideration in selection of patients for lung cancer treatment, including surgery. To assess whether comorbidity contributes to the observed racial differences, we evaluated racial differences in the prevalence of comorbidity and their impact on receipt of surgery., Patients and Methods: A total of 1,314 patients (1,135 white, 179 black) in the Veterans Health Administration diagnosed with early-stage non-small-cell lung cancer in 2007 were included. The effect of comorbidity on surgery was determined by using generalized linear models with a logit link accounting for patient clustering within Veterans Administration Medical Centers., Results: Compared with whites, blacks had greater prevalence of hypertension, liver disease, renal disease, illicit drug abuse, and poor performance status, but lower prevalence of respiratory disease. The impact of most individual comorbidities on receipt of surgery was similar between blacks and whites, and comorbidity did not influence the race-surgery association in a multivariable analysis. The proportion of blacks not receiving surgery as well as refusing surgery was greater than that among whites., Conclusion: Blacks had a greater prevalence of several comorbid conditions and poor performance status; however, the overall comorbidity score did not differ by race. In general, the effect of comorbidity on receipt of surgery was similar in blacks and whites. Racial differences in comorbidity do not fully explain why blacks undergo lung cancer surgery less often than whites.

Objective: Approximately 40,000 incident cancer cases are reported in the Veterans Affairs Central Cancer Registry (VACCR) annually (approximately 3% of U.S. cancer cases). Our objective was to provide the first comprehensive description of cancer incidence as reported in VACCR., Methods: Data were obtained from VACCR for incident cancers diagnosed in VA. Analyses focused on 2007 data. Cancer incidence among VA patients was compared to the general U.S. cancer population., Results: In 2007, 97.5% of VA cancers were diagnosed among men. Approximately 78.5% of newly diagnosed patients were White, 19.0% Black, and 2.5% were another race. Median age at diagnosis was 66 years. The geographic distribution of cancer patients in VA aligns that of VA users. The most commonly diagnosed cancers were similar between VA and the U.S. male cancer population. The five most frequently diagnosed cancers among VA cancer patients were: prostate (31.8%), lung/bronchus (18.8%), colon/rectum (8.6%), urinary bladder (3.6%), and skin melanomas (3.4%). VA patients were diagnosed at an earlier stage of disease for the three most commonly diagnosed cancers--lung/bronchus, colon/rectum, and prostate--compared to the U.S. male cancer population., Conclusions: Registry data indicate that incident cancers in VA in 2007 approximately mirrored those observed among U.S. men.

Purpose: The Veterans Affairs (VA) healthcare system treats approximately 3% of patients with cancer in the United States each year. We measured the quality of nonmetastatic colorectal cancer (CRC) care in VA as indicated by concordance with National Comprehensive Cancer Network practice guidelines (six indicators) and timeliness of care (three indicators)., Patients and Methods: A retrospective medical record abstraction was done for 2,492 patients with incident stages I to III CRC diagnosed between October 1, 2003, and March 31, 2006, who underwent definitive CRC surgery. Patients were treated at one or more of 128 VA medical centers. The proportion of patients receiving guideline-concordant care and time intervals between care processes were calculated., Results: More than 80% of patients had preoperative carcinoembryonic antigen determination (ie, stages II to III disease) and documented clear surgical margins (ie, stages II to III disease). Between 72% and 80% of patients had appropriate referral to a medical oncologist (ie, stages II to III disease), preoperative computed tomography scan of the abdomen and pelvis (ie, stages II to III disease), and adjuvant fluorouracil-based chemotherapy (ie, stage III disease). Less than half of patients with stages I to III CRC (43.5%) had a follow-up colonoscopy 7 to 18 months after surgery. The mean number of days between major treatment events included the following: 26.6 days (standard deviation [SD], 38.2; median, 20 days) between diagnosis and initiation of treatment (in stages II to III disease); 64.8 [corrected] days (SD, 54.9; median, 50 days) between definitive surgery and start of adjuvant chemotherapy (in stages II to III disease); and 444.2 [corrected] days (SD, 182.1; median, 393 days) between definitive surgery and follow-up colonoscopies (in stages I to III disease)., Conclusion: Although there is opportunity for improvement in the area of cancer surveillance, the VA performs well in meeting established guidelines for diagnosis and treatment of CRC.

Objective: The Veterans Affairs (VA) Quality Enhancement Research Initiative (QUERI) seeks to develop partnerships between VA health services researchers and clinical managers, with the goal of designing and evaluating interventions to improve the quality of VA health care., Methods: In the present report we describe one such initiative aimed at enhancing the continuum of colorectal cancer (CRC) care, including diagnosis, treatment and surveillance-the Colorectal Cancer Care Collaborative (C4)., Results: We describe the process and thinking that led to two parallel quality improvement "collaboratives" that addressed (1) CRC screening and diagnostic follow-up and (2) the guideline concordance and timeliness of CRC treatment. Additionally, we discuss ongoing effort to spread lessons learned during the first stages of the project, which initially occurred at only a subset of VA facilities, throughout the VA health care system. The description of this initiative is organized around key questions that must be answered when developing, sustaining and spreading multi-component quality improvement interventions., Conclusion: We conclude with a discussion of lessons learned that we believe would apply to similar initiatives elsewhere, even if they address different clinical issues in health care settings with different organizational structures.

PURPOSE: The Veterans Health Administration (VHA) is the largest cancer care provider in the United States, with the added challenge of serving more than twice the percentage of patients with cancer in rural areas than the national average. The VHA established the National Precision Oncology Program in 2016 to implement and standardize the practice of precision oncology across the diverse VHA system. METHODS: Tumor or peripheral blood specimens from veterans with advanced solid tumors who were eligible for treatment were submitted for next-generation sequencing (NGS) at two commercial laboratories. Annotated results were generated by the laboratories and independently using IBM Watson for Genomics. Levels-of-evidence treatment recommendations were based on OncoKB criteria. RESULTS: From July 2016 to June 2018, 3,698 samples from 72 VHA facilities were submitted for NGS testing, of which 3,182 samples (86%) were successfully sequenced. Most samples came from men with lung, prostate, and colorectal cancers. Thirty-four percent of samples were from patients who lived in a rural area. TP53 , ATM , and KRAS were among the most commonly mutated genes. Approximately 70% of samples had at least one actionable mutation, with clinical trials identified as the recommended option in more than 50%. Mutations in genes associated with a neuroendocrine prostate cancer phenotype were expressed at increased frequency among veterans than in the general population. The most frequent therapies prescribed in response to NGS testing were immune checkpoint inhibitors, EGFR kinase inhibitors, and PARP inhibitors. CONCLUSION: Clinical implementation of precision oncology is feasible across the VHA health care system, including rural sites. Veterans have unique occupational exposures that might inform the nature of the mutational signatures identified here. Importantly, these results underscore the importance of increasing clinical trial availability to veterans. [ABSTRACT FROM AUTHOR]

Colorectal cancer (CRC) accounts for ~9% of all cancers in the Veteran population, a fact which has focused a great deal of the attention of the VA's research and development efforts. A field-based meeting of CRC experts was convened to discuss both challenges and opportunities in precision medicine for CRC. This group, designated as the VA Colorectal Cancer Cell-genomics Consortium (VA4C), discussed advances in CRC biology, biomarkers, and imaging for early detection and prevention. There was also a discussion of precision treatment involving fluorescence-guided surgery, targeted chemotherapies and immunotherapies, and personalized cancer treatment approaches. The overarching goal was to identify modalities that might ultimately lead to personalized cancer diagnosis and treatment. This review summarizes the findings of this VA field-based meeting, in which much of the current knowledge on CRC prescreening and treatment was discussed. It was concluded that there is a need and an opportunity to identify new targets for both the prevention of CRC and the development of effective therapies for advanced disease. Also, developing methods integrating genomic testing with tumoroid-based clinical drug response might lead to more accurate diagnosis and prognostication and more effective personalized treatment of CRC.

BACKGROUND Despite clinical trials demonstrating improved survival with adjuvant chemotherapy (AC) for patients with American Joint Committee on Cancer stages I to III non-small cell lung cancer (NSCLC), it is unclear whether this survival benefit extends to broader populations. The current study evaluated patterns of AC use and examined the impact of AC on survival. METHODS A retrospective analysis was conducted of patients in the Veterans Affairs Central Cancer Registry diagnosed with stages IB to IIIA NSCLC between 2001 and 2008. Descriptive statistics were used to examine patterns of AC use over an 8-year time period. Cox proportional hazards regression analyses were used to estimate hazards ratios (HR) and 95% confidence intervals (95% CIs) to compare mortality risk among patients treated with and without AC. RESULTS Among 14,306 patients with stages IB to IIIA NSCLC, 4929 underwent surgery and 22% of these received AC. The percentages of patients diagnosed in 2001 through 2003, 2004 through 2005, and 2006 through 2008 receiving AC were 7.0%, 29.8%, and 29.5%, respectively. There was no survival benefit with AC noted for patients diagnosed between 2001 and 2003, but AC was associated with improved survival for the period between 2004 and 2005 (HR, 0.78; 95% CI, 0.67-0.91) and 2006 through 2008 (HR, 0.79; 95% CI, 0.69-0.91). Of those patients receiving AC, 89% received platinum-doublet chemotherapy. Carboplatin remained the most common agent, although cisplatin use reached 43% in the period between 2006 and 2008. The HR for cisplatin relative to carboplatin was 0.96 (95% CI, 0.80-1.15). CONCLUSIONS There was a significant increase in the use of AC between 2001 and 2008 and AC was associated with an improvement in overall survival.

PURPOSE: It is imperative to provide quality end-of-life (EOL) care for patients with cancer. Although rates of hospice use within the Veterans Health Administration have improved, antineoplastic administration and intensive care unit (ICU) admission at the EOL, indicators of aggressive care, have not clearly declined over recent years. METHODS: We identified 32,665 veterans diagnosed with stage IV lung, colorectal, or pancreatic cancer who died between 2009 and 2016 using a novel EOL Dashboard Tool created from Veterans Administration Cancer Registry data. This EOL tool reports the incidence of antineoplastic drug use in the last 14 days of life, ICU admission in the last 30 days of life, and hospice admission or consult. Change from 2009 to 2016 was assessed using a repeated measures one-way analysis of variance with post hoc test for linear trend of time for individual cancers and two-way analysis of variance for all cancers combined. RESULTS: Antineoplastic use in the last 14 days of life declined from 6.8% in 2009 to 4.4% in 2016 (P =.03). ICU admission in the last 30 days did not change significantly, from 13.3% in 2009 to 14.7% in 2016. The exception was patients with stage IV lung cancer, in whom ICU admissions increased from 12.9% to 16.2% (P =.01). Patients using hospice services increased from 32.4% to 52.6% (P <.01). CONCLUSION: Although antineoplastic administration at the EOL is declining for veterans with stage IV cancer, ICU admissions are unchanged and becoming more common in stage IV lung cancer despite increasing hospice use.

Purpose: Standard therapy for locally advanced rectal cancer includes neoadjuvant chemoradiation and surgery. Complete response (CR) rates after chemoradiation can be as high as 29%, suggesting that nonoperative management (NOM) may be reasonable with appropriately selected patients. We sought to identify potential NOM candidates.Methods and Materials: Using the Veterans Administration Central Cancer Registry, patients with stage II to III rectal cancer receiving chemoradiation with or without subsequent surgery were identified. Clinical CR (cCR) was assessed by physical examination, endoscopy, or imaging. Kaplan-Meier and log-rank tests were used to assess survival; multivariate analysis was performed using Cox proportional hazards.Results: A total of 1313 patients were identified. Of these, 313 received chemoradiation alone (CRT cohort); 1000 received chemoradiation followed by surgery (CRT + S cohort). Median follow-up was 67.2 months. Median overall survival (OS) was 68.5 months. Median OS was 30.6 months for CRT and 89.3 months for CRT + S (P < .001). Median disease-specific survival (DSS) was 44.8 months for CRT and not reached (NR) for CRT + S (P < .001). Sixty-five CRT patients (20.8%) had a cCR. Median OS for CRT cCR patients was 73.5 months (P = .128 vs CRT + S); median DSS was NR (P = .161 vs CRT + S). One hundred thirty-seven (10.5%) CRT + S patients had a pathologic CR (pCR). Median OS with pCR was 133.7 months (P < .001 vs CRT cCR), and median DSS was NR (P = .276 vs CRT cCR).Conclusions: CRT patients with cCR had similar OS and DSS versus CRT + S patients and similar DSS versus CRT + S patients with a pCR. This suggests that patients with locally advanced rectal cancer with a cCR to CRT have an excellent prognosis and may be candidates for organ preservation. [ABSTRACT FROM AUTHOR]
