The economic burden of metastatic pancreatic cancer.

BACKGROUND: Objectives: Pancreatic cancer (PC) is a costly disease with a limited life-expectancy as it generally presents as an advanced, metastatic disease. Though current literature suggests cost varies by first line treatment, there is limited real-world knowledge about the economic burden of pancreatic cancer. This study describes the economic burden of pancreatic cancer patients overall and by observed first line treatments. METHODS: The IBM MarketScan databases were used to identify adult metastatic PC patients from January 1, 2010 through 3/31/2017. Those without other primary cancers, pregnancy, or prior PC treatment, and with 6 months of continuous enrollment prior to PC were included. Treatment patterns and healthcare utilization and expenditures were measured during the variable-length follow-up period. Continuous measures were presented as per patient per month (PPPM). RESULTS: A total of 6,360 patients met all inclusion criteria. Almost half (46.8%) of patients were untreated. Gemcitabine alone (15.6%) and FOLFIRINOX (11.4%) were the most commonly observed first line regimens. Treated patients incurred $17,513 PPPM (Gemcitabine alone) to $27,889 PPPM (FOLFIRINOX) during follow-up. Untreated patients incurred the highest unadjusted ($30,777 PPPM) and adjusted ($20,392 PPPM) cost. CONCLUSIONS: Metastatic PC patients incur a high economic burden driven by high utilization of healthcare resources, which varies by first line treatment. Also, the high proportion of untreated patients is alarming as these patients may be the most expensive of all patients. There is an unmet need in these patients for effective treatments that also reduce their economic burden.

Healthcare resource utilization and costs of adverse events among patients with metastatic urothelial cancer in USA.

Aim: To estimate incremental costs and healthcare resource utilization (HRU) associated with select severe adverse events (AEs) and AEs of any severity in patients with metastatic urothelial carcinoma receiving first-line (1L) therapy. Materials & methods: Adults treated with 1L systemic therapy between January 2012 and September 2017 with ≥1 urothelial cancer diagnosis were identified using claims data. Per-patient-per-month cost differences and HRU rate ratios comparing patients with and without select AEs were estimated. Results: Patients with any severe select AEs had higher costs than those without (cost difference = $6130 per-patient-per-month; p < 0.001). Healthcare costs and HRU for patients with select AEs were significantly higher versus those without. Conclusion: Select AEs during 1L therapy for metastatic urothelial carcinoma can result in significant burden to patients and healthcare systems.

Epidemiologic, humanistic and economic burden of hepatocellular carcinoma in the USA: a systematic literature review.

AIM: To describe the epidemiologic, humanistic and economic burdens of hepatocellular carcinoma (HCC) in the USA. MATERIALS & METHODS: Studies describing the epidemiology and economic burden from national cohorts, any economic models, or any humanistic burden studies published 2008-2018 were systematically searched. RESULTS: HCC incidence was 9.5 per 100,000 person-years in most recent data, but was ∼100-times higher among patients with hepatitis/cirrhosis. Approximately a third of patients were diagnosed with advanced disease. Patients with HCC experienced poor quality of life. Direct costs were substantial and varied based on underlying demographics, disease stage and treatment received. Between 25-77% of patients did not receive surgical, locoregional or systemic treatment. CONCLUSION: Better treatments are needed to extend survival and improve quality of life for patients with HCC.

Medical oncology referral and systemic therapy of patients with advanced stage urothelial carcinoma.

Aim: To understand physician visit patterns among patients with stage IV (including nonmetastatic [M0] and metastatic [M1] disease) urothelial carcinoma (UC) and understand factors associated with a timely referral to a medical oncologist and systemic treatment. Patients & methods: Retrospective analysis of Surveillance, Epidemiology and End Results-Medicare data. Results: First physician encounter was with a urologist (M0: 69%; M1: 53%) or primary care physician ([PCP]; M0: 19%, M1: 25%) for the majority of patients around UC diagnosis. After the index urologist encounter, most patients had a subsequent medical oncologist visit at a median of 52 days (M0: 69.5 days, M1: 33 days). In an adjusted model, older age, index PCP visit, higher comorbidities and M0 disease were negatively associated with a medical oncologist referral. Among those referred to a medical oncologist, older age, Hispanic or non-Hispanic Black race and not being married were negatively associated with subsequent chemotherapy receipt (p < 0.05). Conclusion: Many patients with advanced UC encounter multiple specialists during their disease course. Older patients or those with a first UC-related encounter with a PCP are less likely to be referred to medical oncology. Once referred to medical oncology, social determinants, including race and marital status, are relevant predictors of receiving chemotherapy.

Treatment patterns and outcomes in pancreatic cancer: Retrospective claims analysis.

BACKGROUND: Pancreatic cancer represents the third leading cause of US cancer deaths, with median survival <1 year. The goal of this study was to describe systemic treatments, healthcare utilization and costs, and overall survival among patients with unresectable/metastatic disease. METHODS: This study used healthcare claims for commercial and Medicare Advantage enrollees diagnosed with pancreatic adenocarcinoma (at index date) during January 01 2010 to 31 May 2017. Included patients were aged ≥18 years, with continuous 6-month preindex enrollment. Patients were excluded by resectable disease, another primary cancer, or pregnancy. Cohorts were based on first-line (LOT1) chemotherapy regimen. RESULTS: Overall, 12 978 patients (mean age 70 years, 51% male) were included, among which 5610 (43%) received chemotherapy. Of those, 23% received gemcitabine monotherapy, 22% gemcitabine-nab paclitaxel, 22% FOLFIRINOX, 3% FOLFOX, and 29% received other regimens. Mean LOT1 duration was 112 days; 60% did not undergo subsequent lines of therapy. Moreover, 50% of patients had an emergency room visit and 45% were hospitalized during LOT1. Among treated and untreated patients, mean total 6-month costs were $52 101. We found that patients receiving FOLFIRINOX had the highest costs, whereas those who received gemcitabine monotherapy had the lowest. Median overall survival (mOS) was 335 days with any first-line treatment. FOLFIRINOX-treated patients had the highest mOS (492 days), whereas gemcitabine monotherapy-treated patients had the lowest (223 days). CONCLUSIONS: A large proportion (57%) of patients with unresectable/metastatic pancreatic cancer did not receive chemotherapy. Healthcare costs were higher for fluorouracil-based regimens, while lower for gemcitabine-based regimens. Survival rates were within expectations for advanced pancreatic cancer.

The Real-World Lifetime Economic Burden of Urothelial Carcinoma by Stage at Diagnosis.

BACKGROUND: Urothelial carcinoma (UC) is generally diagnosed early and may incur significant lifetime costs. This study estimated, from the payer's perspective, the lifetime costs among patients diagnosed with UC according to stage at diagnosis. METHODS: This retrospective analysis of the linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database identified patients ≥66 years with newly diagnosed UC from 2004-2013. Patients were followed from UC diagnosis to death or last follow-up to estimate lifetime costs. Costs were allocated to 3 phases: diagnosis (≤3 months after diagnosis), terminal (≤3 months before death), and continuation (months between diagnosis and terminal phases). Survival-adjusted lifetime costs (total and major UC-related) were estimated for patients with UC based on stage at diagnosis (stages 0 through IV) and in a subgroup of patients receiving ≥1 systemic line of chemotherapy (LOC). RESULTS: The sample included 15,588 patients: 3,446 stage 0 (8% ≥1 LOC; median [IQR] follow-up in months: 44 [23-71]); 3,902 stage I (12% ≥1 LOC; 33 [15-62]); 4,301 stage II (26% ≥1 LOC; 17 [7-39]); 1,612 stage III (25% ≥1 LOC; 17 [7-42]); and 2,327 stage IV (33% ≥1 LOC; 8 [3-18]). Median age was 78 years and 72% were male. Mean lifetime costs were lowest for stage IV patients (stage 0, $151,626; stage 1, $150,123; stage II, $149,728; stage III, $190,996; stage IV, $117,503). Hospitalizations not involving a cystectomy contributed about half of lifetime costs across all stages. Cystectomy contributed 2-13% of the total lifetime UC costs ($3,356 stage 0; $7,011 stage I; $11,855 stage II; $25,509 stage III; $11,693 stage IV). UC-related office visits contributed 8-15% of lifetime costs ($11,717 stage 0; $14,611 stage I; $19,882 stage II; $21,480 stage III; $17,820 stage IV). CONCLUSION: UC continues to be a costly cancer with stage III patients having highest lifetime costs. Hospitalizations drive most of the lifetime costs across all stages; most of these hospitalizations did not involve costs related to cystectomy. Treatment plans requiring shorter and fewer hospitalizations may lessen the economic burden of UC.

Comparative efficacy and safety of antidiabetic drug regimens added to metformin monotherapy in patients with type 2 diabetes: a network meta-analysis.

INTRODUCTION: When first line therapy with metformin is insufficient for patients with type 2 diabetes (T2D), the optimal adjunctive therapy is unclear. We assessed the efficacy and safety of adjunctive antidiabetic agents in patients with inadequately controlled T2D on metformin alone. MATERIALS AND METHODS: A search of MEDLINE and CENTRAL, clinicaltrials.gov, regulatory websites was performed. We included randomized controlled trials of 3-12 months duration, evaluating Food and Drug Administration or European Union approved agents (noninsulin and long acting, once daily basal insulins) in patients experiencing inadequate glycemic control with metformin monotherapy (≥ 1500 mg daily or maximally tolerated dose for ≥ 4 weeks). Random-effects network meta-analyses were used to compare the weighted mean difference for changes from baseline in HbA1c, body weight (BW) and systolic blood pressure (SBP), and the risk of developing hypoglycemia, urinary (UTI) and genital tract infection (GTI). RESULTS: Sixty-two trials evaluating 25 agents were included. All agents significantly reduced HbA1c vs. placebo; albeit not to the same extent (range, 0.43% for miglitol to 1.29% for glibenclamide). Glargine, sulfonylureas (SUs) and nateglinide were associated with increased hypoglycemia risk vs. placebo (range, 4.00-11.67). Sodium glucose cotransporter-2 (SGLT2) inhibitors, glucagon-like peptide-1 analogs, miglitol and empagliflozin/linagliptin significantly reduced BW (range, 1.15-2.26 kg) whereas SUs, thiazolindinediones, glargine and alogliptin/pioglitazone caused weight gain (range, 1.19-2.44 kg). SGLT2 inhibitors, empagliflozin/linagliptin, liraglutide and sitagliptin decreased SBP (range, 1.88-5.43 mmHg). No therapy increased UTI risk vs. placebo; however, SGLT2 inhibitors were associated with an increased risk of GTI (range, 2.16-8.03). CONCLUSIONS: Adding different AHAs to metformin was associated with varying effects on HbA1c, BW, SBP, hypoglycemia, UTI and GTI which should impact clinician choice when selecting adjunctive therapy.
