Universal Viral Screening of Patients with Newly Diagnosed Cancer in the United States: A Cost-efficiency Evaluation.

Recommendations for universal screening of patients with cancer for hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) are inconsistent. A recent multisite screening study (S1204) from the SWOG Cancer Research Network found that a substantial number of patients with newly diagnosed cancer had previously unknown viral infections. The objective of this study was to determine the cost-efficiency of universal screening of patients with newly diagnosed cancer. We estimated the cost-efficiency of universal screening of new cancer cases for HBV, HCV, or HIV, expressed as cost per virus detected, from the health care payer perspective. The prevalence of each virus among this cohort was derived from S1204. Direct medical expenditures included costs associated with laboratory screening tests. Costs per case detected were estimated for each screening strategy. Secondary analysis examined the cost-efficiency of screening patients whose viral status at cancer diagnosis was unknown. Among the possible options for universal screening, screening for HBV alone ($581), HCV alone ($782), HBV and HCV ($631) and HBV, HCV, and HIV ($841) were most efficient in terms of cost per case detected. When screening was restricted to patients with unknown viral status, screening for HBV alone ($684), HBV and HCV ($872), HBV and HIV ($1,157), and all three viruses ($1,291) were most efficient in terms of cost per newly detected case. Efficient viral testing strategies represent a relatively modest addition to the overall cost of managing a patient with cancer. Screening for HBV, HCV, and HIV infections may be reasonable from both a budget and clinical standpoint. SIGNIFICANCE: Screening patients with cancer for HBV, HCV, and HIV is inconsistent in clinical practice despite national recommendations and known risks of complications from viral infection. Our study shows that while costs of viral screening strategies vary by choice of tests, they present a modest addition to the cost of managing a patient with cancer.

Increased Incidence of Human Papillomavirus-Related Precancer or Second Malignancy Among Allogeneic Stem Cell Transplantation Patients: A SEER-Medicare Population Study.

Each year, more than 8000 allogeneic stem cell transplantations (allo-SCT) are performed in the United States, with approximately 30% of these patients age ≥60 years. Allo-SCT recipients are at increased risk for developing human papillomavirus (HPV)-related precancer or second malignancy. It is important to evaluate HPV-related precancer or second malignancy among allo-SCT recipients to develop or enhance screening and preventive practice guidelines to improve patients' survival and quality of life. In this retrospective matched case-control study, we estimated the cumulative incidence of HPV-related precancer or second malignancy in both male and female Medicare beneficiaries who underwent allo-SCT and compared it with the cumulative incidence in non-SCT controls and noncancer controls. Hematologic cancer patients age ≥18 years who underwent allo-SCT between 2002 and 2011 were matched 1:5 to non-SCT controls and to noncancer controls by age, sex, race/ethnicity, and duration of follow-up. Proportions of HPV-related precancer or second malignancy were estimated and compared between cases and controls using the chi-square test and logistic regression. Kaplan-Meier cumulative incidences were estimated and compared using log-rank tests. We identified 700 allo-SCT cases (median age, 64 years; median follow-up post-transplantation, 4.3 years) matched with 3159 non-SCT controls and 3302 noncancer controls. Approximately 3.7% of allo-SCT cases developed HPV-related precancer or second malignancy post-transplantation, compared with 1.9% of the non-SCT controls and 1.1% of the noncancer controls. The odds ratio of developing HPV-related precancer or second malignancy of allo-SCT cases compared with non-SCT controls and noncancer controls was 2.0 (95% confidence interval [CI], 1.25 to 3.18) and 3.5 (95% CI, 2.1 to 5.8), respectively. Both allo-SCT cases and non-SCT controls had significantly higher proportions and odds of developing HPV-related precancer or second malignancy compared with noncancer controls. The 5-year cumulative incidence in allo-SCT cases was 5%, compared with 2.1% in non-SCT controls and 1.2% in noncancer controls. The cumulative incidence of HPV-related precancer or second malignancy was statistically significantly higher in the allo-SCT than in either of the 2 matched control groups, and the non-SCT controls had a higher cumulative incidence of HPV-related precancer or second malignancy than the noncancer controls. The allo-SCT cases were at increased risk of developing HPV-related precancer or second malignancy compared with the non-SCT controls and noncancer controls. Routine screening of HPV-related precancer or second malignancy in allo-SCT recipients is needed to help prevent HPV-related precancer or second malignancy. © 2021 American Society for Transplantation and Cellular Therapy.

Cost-Effectiveness Analysis of Hepatitis B Virus Screening and Management in Patients With Hematologic or Solid Malignancies Anticipating Immunosuppressive Cancer Therapy.

PURPOSE: National hepatitis B virus (HBV) screening recommendations for patients with cancer anticipating systemic anticancer therapy range from universal screening to screening based on risk of HBV infection, cancer therapy-specific risk of HBV reactivation, or both. We conducted cost-effectiveness analyses to identify optimal HBV screening strategies. PATIENTS AND METHODS: We constructed decision-analytic models to analyze three strategies (no screening, universal screening, and selective screening based on use of an HBV infection risk tool) for hypothetic cohorts of patients anticipating anticancer therapy at high or lower risk for HBV reactivation. Model parameters were drawn from previously published studies, the SEER-Medicare database, and other online resources. Outcomes included lifetime expected cost, quality-adjusted life expectancy, and incremental cost-effectiveness ratio, measured in US dollars required to gain an additional quality-adjusted life-year (QALY). RESULTS: For patients at high reactivation risk, universal screening dominated (ie, was cheaper and more effective than) the other two strategies. Universal screening was associated with a gain in life expectancy of 0.01 QALY compared with no screening and cost $76.06 less than no screening and $4.34 less than selective screening. For those at lower reactivation risk, universal screening still dominated selective screening; however, the incremental cost-effectiveness ratio of the universal screening strategy compared with no screening was $186,917 per QALY gained. CONCLUSION: Universal HBV screening is cost effective and cheaper for patients receiving anticancer therapy associated with a high reactivation risk. For patients receiving anticancer therapy associated with a lower reactivation risk, universal screening is not cost effective.

Global Epidemiology, Prevention, and Management of Hepatocellular Carcinoma.

The incidence rate of hepatocellular carcinoma (HCC) is rising. It is one of the most common cancers worldwide and accounts for substantial morbidity and mortality. Chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and nonalcoholic fatty liver disease (NAFLD) are the most important etiologies of HCC, and effective screening and management strategies are crucial to reduce the HCC risk. For HBV, which accounts for the majority of HCC cases, most infections were acquired via perinatal and early horizontal transmission. Universal vaccination of newborns has led to a decline in HCC incidence compared with the pre-vaccination era. Effective antiviral therapies with nucleos(t)ide analogues or pegylated interferon reduced the incidence of HCC. For HCV, the emergence of effective direct-acting antiviral (DAA) agents has substantially improved cure rates; therefore all patients with HCV should be considered for DAA treatment. The most important obstacle in eliminating HCV is access to therapy. For NAFLD, the global incidence is increasing rapidly, thus its impact on HCC incidence may be explosive. Progression to HCC in NAFLD happens particularly in those with nonalcoholic steatohepatitis (NASH) and exacerbated by metabolic syndrome, or PNPLA3 gene polymorphism. Lifestyle changes are imperative while drug therapy has yet to demonstrate substantive protective effects on HCC prevention. For management of HCC, early diagnosis via imaging surveillance among persons with HCC risk factors remains the most important strategy to identify early-stage disease appropriate for resection or transplantation.

Late effects and healthcare needs of survivors of allogeneic stem cell transplantation: a qualitative study.

PURPOSE: This qualitative study of survivors of allogeneic stem cell transplantation (SCT) for haematological malignancy explored attitudes about late effects of therapy, healthcare issues and information needs. METHODS: We conducted 12 indepth cognitive interviews and three focus groups of patients who had previously had SCT and were without recurrence of their primary disease. We used grounded theory methods, where themes emerged from consensus between cocoders. Health-related quality of life was assessed with the short-form 36 (SF-36). RESULTS: The study included 22 patients (50% female; 95% white; mean age 47 years). The mean time from SCT was 5.2 years (±1.4 years). Most had low SF-36 scores. Participants discussed late effects of therapy, most commonly graft-versus-host disease, and how they impacted their quality of life. They reported frequent healthcare use and cancer screening after SCT and discussed problems affording care and interacting with insurance companies. Participants shared sources of health information (eg, preferring providers as their primary sources of information, but also learnt from websites, medical journals and peer experiences) and identified information barriers (eg, feeling 'on their own' insofar as they did not have targeted care for their needs), and expressed importance of anticipatory guidance regarding infertility. Overall, participants' personal issues and social influences impacted survivors' needs and attitudes. CONCLUSIONS: SCT survivors face continuing and lasting health effects. The factors impacting survivorship needs are complex and may be interrelated. Future research should study the affect of incorporating personal and social issues into existing clinical SCT programmes on survivors' quality of life.

Hematopoietic stem cell transplantation among patients with leukemia of all ages in Texas.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is an effective but expensive medical procedure to which some ethnic minorities, the elderly, and those without insurance have been shown to have limited access. The purpose of the current study was to determine whether socioeconomic factors were associated with HSCT usage rates in patients with leukemia. METHODS: The authors identified 6574 patients with acute lymphocytic leukemia, chronic lymphocytic leukemia, acute myelogenous leukemia, chronic myelogenous leukemia, or other leukemias from the 1999 Texas Hospital Inpatient Discharge Public Use Data File. Of these patients, 1604 received an autologous or allogeneic HSCT. The authors assessed patients' ethnicity, payer status, age, gender, and comorbid medical conditions. Logistic regression was used to control for patient characteristics and to evaluate associations among payer status, ethnicity, and HSCT use. P < or = 0.05 indicated statistical significance. RESULTS: Patients who self-paid had the highest rate of HSCT use in all age groups (32%; P < or = 0.01) and in the adult group (36%; P = 0.11). Elderly patients with Medicare had a low rate of HSCT use (17%; P = 0.13). Logistic regression showed no statistically significant associations between payer status or ethnicity and HSCT use. However, elderly women were significantly less likely to undergo HSCT than elderly men (odds ratio, 0.34; P < or = 0.01). CONCLUSIONS: The lack of statistically significant differences in HSCT use among adult patients with leukemia was surprising because previous studies had shown differences in HSCT by ethnicity and insurance.
