RESUMO

PURPOSE: This study assessed the trial-level association between event-free survival (EFS) and overall survival (OS) in gastric or gastroesophageal junction (GEJ) adenocarcinoma in the neoadjuvant ± adjuvant settings. EXPERIMENTAL DESIGN: A systematic literature review was conducted to identify randomized controlled trials (RCT) that evaluated neoadjuvant therapies with or without adjuvant therapies for gastric or GEJ adenocarcinoma. A meta-analysis was performed using weighted linear regressions of the treatment effect of OS on the treatment effect of EFS. The coefficient of determination (R²) and associated 95% confidence interval (CI) were used to evaluate the association between treatment effects of EFS and OS. The threshold used for defining good trial-level surrogacy was a correlation coefficient (R) of 0.8 or R² of 0.65, based on prior literature. Sensitivity analyses were performed to assess the robustness of the association with divergent study designs, including study population, inclusion of adjuvant therapy, and definitions of EFS and OS. RESULTS: The main analysis included 16 comparisons from 15 RCTs. The log(HR) of EFS was a significant predictor of log(HR) of OS, with an estimated coefficient of 0.72 (P < 0.001) and R² = 0.75 (95% CI, 0.49-0.95), indicating that EFS was a good surrogate outcome for OS. The results of the sensitivity analyses were consistent with the primary results, with R² ranging from 0.76 to 0.89. CONCLUSIONS: This study suggests that EFS is a good surrogate for OS in gastric or GEJ adenocarcinoma in the neoadjuvant ± adjuvant setting.

RESUMO

OBJECTIVES: Liposomal irinotecan (nal-IRI) is a topoisomerase inhibitor proven to improve survival in metastatic pancreatic cancer (mPC). This study describes real-world characteristics of patients treated with nal-IRI for mPC. METHODS: Patients 18 years or older diagnosed with stage IV mPC and treated with nal-IRI were selected retrospectively from a deidentified electronic health record database of more than 2 million US cancer patients. Demographics, clinical and dosing characteristics, and treatment outcomes were collected. RESULTS: Of 257 total patients, 145 (57%) received nal-IRI as first- or second-line therapy. Median nal-IRI treatment duration was 51 days, longer when nal-IRI was used as first/second versus as third-line therapy or later (62 vs 44.5 days). Seventy patients (27.2%) experienced dose modification. Median time to treatment discontinuation was 2.3 versus 1.6 months for first-/second- versus third-line therapy or later, respectively. Median overall survival from nal-IRI initiation was 5.6 versus 4.1 months for first-/second- versus third-line therapy or later, respectively. Prior irinotecan treatment, baseline serum albumin less than 40 g/L, and baseline neutrophil-to-lymphocyte ratio greater than 5 were associated with reduced overall survival. CONCLUSIONS: This is the first large US study of real-world US mPC patients treated with nal-IRI. These results, comparable to the NAPOLI-1 trial, can help inform future studies and the efficacy of nal-IRI in mPC therapy.

RESUMO

BACKGROUND: Prostate cancer is the most frequently diagnosed cancer in men in the United States. There is scant real-world evidence characterizing the care utilization and clinical outcomes associated with the use of therapies currently approved by the US Food and Drug Administration (FDA) for patients with metastatic castrate-resistant prostate cancer (CRPC). OBJECTIVE: To describe the real-world treatment patterns, healthcare costs, and survival rates of patients with metastatic CRPC and bone metastases who have commercial or Medicare coverage. METHODS: This retrospective observational study was conducted using medical and pharmacy claims from the Humana research database for male patients who had Medicare or commercial coverage and were aged 55 to 89 years at the initiation of treatment for metastatic CRPC. Three inclusion criteria were used to identify appropriate patients for the 2 cohorts, including (1) a diagnosis of prostate cancer (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 185.x); (2) a diagnosis of bone metastasis (ICD-9-CM code 198.5) between 2013 and 2014; and (3) a healthcare insurance claim indicating a prescription for an FDA-approved first-line treatment for metastatic CRPC. Subsequent lines of treatment were also identified through the healthcare claims data. The 2-year survival rate was calculated and controlled for demographic and clinical characteristics, and the total costs (medical plus pharmacy) were calculated for the 6 months postindex. RESULTS: A total of 1855 patients met the study inclusion criteria. Of these patients, 660 (35.6%) received at least 1 medication. The patient count by line of treatment was 660 (100%) who received first-line therapy, 380 (57.6%) who received second-line treatment, 204 (30.9%) who received third-line therapy, and 107 (16.2%) who received fourth-line therapy. The medication distribution by line of treatment (using first-, second-, third-, or fourth-line therapy for each drug) was abiraterone acetate (50.5%, 61.3%, 68.6%, 75.7%); enzalutamide (15.6%, 39.2%, 54.4%, 71.0%); sipuleucel-T (9.2%, 13.9%, 20.1%, 20.6%); radium-223 dichloride (1.7%, 2.6%, 7.4%, 13.1%); cabazitaxel (2.3%, 5.5%, 16.2%, 19.6%); and docetaxel (22.1%, 32.1%, 42.6%, 48.6%). The total monthly unadjusted healthcare costs for patients who received an FDA-approved treatment was much higher ($9435) than for patients with metastatic prostate cancer who did not receive an FDA-approved treatment ($5055), and the 2-year survival rate for patients who received an FDA-approved treatment was 57.1% (25th percentile, 250 days; 50th percentile, 541 days). CONCLUSIONS: The most common first-line treatment for patients with commercial or Medicare coverage who had metastatic CRPC was abiraterone or enzalutamide. Hormone therapies used as monotherapy were the most frequently used treatment, and their concomitant administration with other treatments was the second most common treatment pattern. Additional clinical studies are needed to further elucidate the treatment sequencing for patients with metastatic CRPC.

RESUMO

BACKGROUND: There are a lack of guideline recommendations for patients with metastatic castration-resistant prostate cancer (mCRPC) undergoing treatment progression and sequencing. Understanding treatment patterns and associated utilization and costs may help inform stakeholders and guide decision making. OBJECTIVE: To describe treatment patterns and health care costs in prostate cancer (PC) patients with bone metastases treated with agents approved by the FDA for mCRPC. METHODS: 2 large integrated claims databases (MarketScan and PharMetrics) were used to identify males aged ≥ 18 years who were diagnosed and treated for PC (ICD-9-CM code 185.xx or 233.4) with bone metastases (ICD-9-CM code 198.5) from June 2013 to September 2014. Patients were required to be continuously enrolled for ≥ 6 months before and after initiation of treatment with abiraterone, cabazitaxel, docetaxel, enzalutamide, mitoxantrone, radium-223, sipuleucel-T, or other chemotherapy. Study endpoints included lines of therapy, health care resource utilization per patient per month (PPPM), PPPM costs, and mortality rate. Descriptive analysis was completed for the study sample, and survival function was calculated via Kaplan-Meier estimates. RESULTS: There were 953 patients meeting all inclusion criteria in the MarketScan database and 565 patients in the PharMetrics database. The median follow-up time was 18 months (interquartile range [IQR] = 14-23) for MarketScan and 14 months (IQR = 11-18) for PharMetrics. Mean age (SD) was 71 (± 10.7) and 66 (± 9.3) years, respectively. Before mCRPC treatment initiation, patients received palliative radiation therapy and bone antiresorptive therapy. For MarketScan and PharMetrics, respectively, 14.0% and 18.2% of patients received radiation therapy, 36.1% and 40.0% received denosumab; 16.5% and 16.8% received zoledronic acid; and 0.2% and 0.8% received pamidronate. Across both databases, abiraterone was the most commonly received bone metastasis treatment agent across all lines of therapy, except fourth line. Radium-223, cabazitaxel, and mitoxantrone were the least utilized therapies. The median cost PPPM during the post-index period was $10,916 (IQR=$5,334-$13,457) in MarketScan and $10,292 (IQR = $7,245-$14,699) in PharMetrics. The cost PPPM during the 6-month pre-index period was $2,643 (IQR = $850-$4,357) in MarketScan and $2,742 (IQR = $1,484-$4,730) in PharMetrics. CONCLUSIONS: Patients were treated mainly with abiraterone across most lines of care, with radium-223, cabazitaxel, and mitoxantrone as the least utilized therapies. Median costs PPPM increased by approximately $8,900 after initiation of FDA-approved agents for mCRPC, with the largest increase in cost stemming from oral medications.

RESUMO

OBJECTIVES: To evaluate the economic burden of treating skeletal-related events (SREs) in prostate cancer (PC) patients with bone metastasis from an insurer perspective. METHODS: We conducted a retrospective cohort analysis using claims data. PC patients with bone metastasis were identified in the MarketScan Databases between January 1, 2004, and March 1, 2014. The propensity score matching approach was used to match patients with SREs to those without SREs. A pseudo-SRE date was assigned to the control group. We compared 6-month and 12-month total costs of patients between two groups after the SRE or pseudo-SRE date. All costs were adjusted to 2014 US$. RESULTS: We identified 4083 PC men with bone metastasis, from which 787 patients with SREs were matched (1:1) to those without SREs. On average, the total 6-month cost of treating patients with SREs was $43,746 compared with $25,956 in the matched control cohort (P < 0.05). The largest proportion of differences in costs between the two groups was incurred in the first month after the SRE index date or the pseudo-SRE date ($14,979 vs. $4,849; P < 0.05) and was mostly attributable to outpatient visits (43.4%; P < 0.05) and inpatient hospitalization (33.1%; P < 0.05). The total cost per patient over the 12-month period was $22,171 higher among patients with SREs than among patients without SREs (P < 0.05). CONCLUSIONS: Our findings suggest that SREs impose considerable burden on health resource utilization for payers. Costs attributable to SREs were substantial. Most costs were incurred in the first month after the occurrence of SREs. Although costs decreased thereafter, they remained significantly higher for patients with SREs in subsequent months compared with patients without SREs.

RESUMO

Sorafenib is the only Food and Drug Administration (FDA)-approved first-line therapy shown to have survival benefit for patients with advanced hepatocellular carcinoma (HCC). Patients with advanced HCC are often but not exclusively transferred from non-oncologists to oncologists to initiate systemic therapy. The objective of this study was to assess whether sorafenib prescribing by non-oncologists has any impact on utilization, adverse effects, cost or outcome.This was a retrospective cohort study utilizing data from patients prescribed sorafenib for HCC within Veterans Health Administration hospitals with 100% chart abstraction to confirm HCC diagnosis, identify prescribing provider specialty (oncology versus gastroenterology/hepatology), and obtain data required for cancer staging by the Barcelona Clinic Liver Cancer (BCLC) system. The primary outcome was overall survival from the time of sorafenib prescription.A total of 4903 patients who prescribed sorafenib for HCC were identified, for whom 340 patients (6.9%) were prescribed drug by a non-oncologist (Onc). BCLC Stage, age, Child-Turcotte-Pugh score, and comorbidity indices were similar between patients prescribed sorafenib by oncologists and non-oncologists. Oncologists more often discontinued sorafenib due to progression, whereas non-oncologists were more likely to continue sorafenib until death resulting in greater pill utilization and cost. Overall survival in both unadjusted and multivariable models showed no significant impact of prescriber type on survival (222 vs 217 days, P = .96), confirmed with propensity-matched subcohorts.Similar survival outcomes were observed for patients with HCC prescribed sorafenib by non-oncologists and oncologists, suggesting that non-oncologists with expertise in the management of HCC can safely and effectively administer sorafenib.

RESUMO

BACKGROUND & AIMS: It is important to quantify medical costs associated with hepatocellular carcinoma (HCC), the incidence of which is rapidly increasing in the United States, for development of rational healthcare policies related to liver cancer surveillance and treatment of chronic liver disease. We aimed to comprehensively quantify healthcare costs for HCC among patients with cirrhosis in an integrated health system and develop a model for predicting costs that is based on clinically relevant variables. METHODS: Three years subsequent to liver cancer diagnosis, costs accrued by patients included in the Veteran's Outcome and Cost Associated with Liver disease cohort were compiled by using the Department of Veterans Affairs Corporate Data Warehouse. The cohort includes all patients with HCC diagnosed in 2008-2010 within the VA with 100% chart confirmation as well as chart abstraction of tumor and clinical characteristics. Cancer cases were matched 1:4 with non-cancer cirrhosis controls on the basis of severity of liver disease, age, and comorbidities to estimate background cirrhosis-related costs. Univariable and multivariable generalized linear models were developed and used to predict cancer-related overall cost. RESULTS: Our analysis included 3188 cases of HCC and 12,722 controls. The mean 3-year total cost of care in HCC patients was $154,688 (standard error, $150,953-$158,422) compared with $69,010 (standard error, $67,344-$70,675) in matched cirrhotic controls, yielding an incremental cost of $85,679; 64.9% of this value reflected increased inpatient costs. In univariable analyses, receipt of transplantation, Barcelona Clinic Liver Cancer (BCLC) stage, liver disease etiology, hospital academic affiliation, use of multidisciplinary tumor board, and identification through surveillance were associated with cancer-related costs. Multivariable generalized linear models incorporating transplantation status, BCLC stage, and multidisciplinary tumor board presentation accurately predicted liver cancer-related costs (Hosmer-Lemeshow goodness of fit; P value ≅ 1.0). CONCLUSIONS: In a model developed to comprehensively quantify healthcare costs for HCC among patients with cirrhosis in an integrated health system, we associated receipt of liver transplantation, BCLC stage, and multidisciplinary tumor board with higher costs. Models that predict total costs on the basis of receipt of liver transplantation were constructed and can be used to model cost-effectiveness of therapies focused on HCC prevention.

RESUMO

PURPOSE: There is limited information on the use of data visualization tools for health services research applications. We provide a proof-of-concept application that focuses on claims-based measures of palliative radiation therapy. We investigate whether a guided, data-driven investigation contributes information for subsequent statistical analysis and algorithm development. METHODS: This retrospective cohort study used linked registry and claims data on men who were diagnosed with stage IV M0 or stage IV M1b prostate cancer between 2005 and 2009, with associated claims from 2005 through 2010, and receiving radiation therapy. Preprocessing of data was accomplished by using EventFlow software to investigate longitudinal patterns in claims for radiation therapy in the 13 months after cancer diagnosis. Guided by results from EventFlow, we developed descriptive statistics to investigate the length of radiation therapy, use of bone metastasis coding, and mortality between M1b and M0 patients. RESULTS: A total of 1,151 patients met the inclusion criteria. Taking advantage of the novel aggregation capability of EventFlow, we observed differences in the length of radiation therapy and the use of bone metastasis coding between men with (M1b) and without (M0) a diagnosis of bone metastasis. Seventy-nine percent of M1b patients received radiation for a duration ≤ 4 weeks, which suggested palliative radiation (to the bone). Seventy-six percent of M0 patients received radiation for ≥ 6 weeks, which suggested radiation to the prostate. Mortality was higher among those who received a shorter duration of radiation therapy compared with those who received a longer duration of therapy. CONCLUSION: Use of EventFlow, followed by statistical analysis of the linked registry and claims data, identified useful components of a claims-based measure of radiation to the bone.

RESUMO

PURPOSE/OBJECTIVE(S): Skeletal-related events (SREs), which include radiation to the bone (RtB), can occur among patients with bone metastasis (BM). There is a recognized potential for misclassification of RtB when using claims data. We compared alternative measures of RtB to better understand their impact on SRE prevalence and SRE-related mortality. METHODS AND MATERIALS: We analyzed data for stage IV prostate cancer (PCa) cases identified between 2005 and 2009 in the Surveillance, Epidemiology, and End Results registry linked with Medicare claims. We created two measures of RtB: 1) a literature-based measure requiring the presence of a prior claim with a BM code; 2) a new measure requiring either that the BM code coincided with the radiation episode or that the duration of the radiation episode was less than or equal to 4 weeks. We estimated adjusted hazard ratios of an SRE using both measures among stratified samples: no metastasis (M0), metastasis to bone (M1b) and other sites (M1c). RESULTS: The study sample included 5,074 men with stage IV PCa (median age 77 years), of whom 22% had M0, 54% had M1b, and 24% had M1c disease at time of PCa diagnosis. Based on Approaches 1 and 2, the proportion with probable RtB was 5% and 8% among M0, 30% and 30% among M1b, and 25% and 27% among M1c patients. Among M0 patients, the adjusted hazard ratio (AHR) associated with an SRE was 1.27 when using Approach 1 (95% confidence interval, CI: 0.95-1.7) and 1.49 when using Approach 2 (95% CI: 1.14-1.96). However, the impact of SREs on mortality did not differ between both approaches among M1b and M1c patients. CONCLUSION: We found that alternative measures used to define RtB as SRE in claims data impact conclusions regarding the effect of SREs on mortality among M0 but not M1 patients.

RESUMO

BACKGROUND & AIMS: Little is known about provider and health system factors that affect receipt of active therapy and outcomes of patients with hepatocellular carcinoma (HCC). We investigated patient, provider, and health system factors associated with receipt of active HCC therapy and overall survival. METHODS: We performed a national, retrospective cohort study of all patients diagnosed with HCC from January 1, 2008 through December 31, 2010 (n = 3988) and followed through December 31 2014 who received care through the Veterans Administration (128 centers). Outcomes were receipt of active HCC therapy (liver transplantation, resection, local ablation, transarterial therapy, or sorafenib) and overall survival. RESULTS: In adjusted analyses, receiving care at an academically affiliated Veterans Administration hospital (odds ratio [OR], 1.97; 95% confidence interval [CI], 1.60-2.41) or a multi-specialist evaluation (OR, 1.60; 95% CI, 1.15-2.21), but not review by a multidisciplinary tumor board (OR, 1.19; 95% CI, 0.98-1.46), was associated with a higher likelihood of receiving active HCC therapy. In time-varying Cox proportional hazards models, liver transplantation (hazard ratio [HR], 0.22; 95% CI, 0.16-0.31), liver resection (HR, 0.38; 95% CI, 0.28-0.52), ablative therapy (HR, 0.63; 95% CI, 0.52-0.76), and transarterial therapy (HR, 0.83; 95% CI, 0.74-0.92) were associated with reduced mortality. Subspecialist care by hepatologists (HR, 0.70; 95% CI, 0.63-0.78), medical oncologists (HR, 0.82; 95% CI, 0.74-0.91), or surgeons (HR, 0.79; 95% CI, 0.71-0.89) within 30 days of HCC diagnosis, and review by a multidisciplinary tumor board (HR, 0.83; 95% CI, 0.77-0.90), were associated with reduced mortality. CONCLUSIONS: In a retrospective cohort study of almost 4000 patients with HCC cared for at VA centers, geographic, provider, and system differences in receipt of active HCC therapy are associated with patient survival. Multidisciplinary methods of care delivery for HCC should be prospectively evaluated and standardized to improve access to HCC therapy and optimize outcomes.

RESUMO

Hepatocellular carcinoma (HCC) is a leading cause of morbidity and mortality in cirrhosis patients. This provides an opportunity to target the highest-risk population, yet surveillance rates in the United States and Europe range from 10% to 40%. The goal of this study was to identify barriers to HCC surveillance, using data from the Veterans Health Administration, the largest provider of liver-related health care in the United States. We included all patients 75 years of age or younger who were diagnosed with cirrhosis from January 1, 2008, until December 31, 2010. The primary outcome was a continuous measure of the percentage of time up-to-date with HCC surveillance (PTUDS) based on abdominal ultrasound (secondary outcomes included computed tomography and magnetic resonance imaging). Among 26,577 patients with cirrhosis (median follow-up = 4.7 years), the mean PTUDS was 17.8 ± 21.5% (ultrasounds) and 23.3 ± 24.1% when any liver imaging modality was included. The strongest predictor of increased PTUDS was the number of visits to a specialist (gastroenterologist/hepatologist and/or infectious diseases) in the first year after cirrhosis diagnosis; the association between visits to a primary care physician and increasing surveillance was very small. Increasing distance to the closest Veterans Administration center was associated with decreased PTUDS. There was an inverse association between ultrasound lead time (difference between the date an ultrasound was ordered and requested exam date) and the odds of it being performed: odds ratio = 0.77, 95% confidence interval 0.72-0.82 when ordered > 180 days ahead of time; odds ratio = 0.90, 95% confidence interval 0.85-0.94 if lead time 91-180 days. CONCLUSIONS: The responsibility for suboptimal surveillance rests with patients, providers, and the overall health care system; several measures can be implemented to potentially increase HCC surveillance, including increasing patient-specialist visits and minimizing appointment lead time.

RESUMO

PURPOSE: The development of skeletal-related events (SREs) (pathologic fracture, need for surgery and/or radiation to bone, spinal cord compression, and hypercalcemia of malignancy) in metastatic prostate cancer (MPC) is associated with worsened pain and compromised quality of life. Opioids are frequently used throughout the course of SRE treatment. This study describes the treatment patterns and incremental use of opioids in MPC patients diagnosed with SREs. METHODS: PC patients with bone metastases newly diagnosed with an SRE between January 1, 2005, and September 30, 2014, were identified using MarketScan Commercial and Medicare databases. Included patients were aged ≥40 years, had medical/pharmacy benefits for ≥12 months before (preindex) and ≥6 months after (postindex) diagnosis, and were without evidence of other primary cancers. Patients were categorized as nonusers of opioids (<10 days), short-term users (≥10 and <60 days), or long-term users (≥60 days) and further by SRE type. Opioid type, proportion of time on opioids, morphine-equivalent dose, adjuvant medications, and radiation use before and after SRE diagnosis were evaluated. FINDINGS: A total of 1071 eligible patients were identified (mean age, 71 years; 10.8% had chronic pain at baseline). The most common SRE types present were radiation (60.2%), radiation and bone surgery (15.0%), pathologic fracture (7.2%), and bone surgery (6.5%). Opioid use increased from 49.9% preindex to 53.3% postindex (P < 0.0001). The proportion of time on opioids doubled after SRE (pre, 0.3 vs post, 0.6; P < 0.0001). A greater percentage of patients used only opioids after an SRE (pre, 11.0%; post, 46.1% [P < 0.0001]), while a lesser percentage of patients used only radiation after an SRE (pre, 36.0%; post, 4.7% [P < 0.0001]). An increase was observed in patients using neither radiation nor opioids (pre, 14.5%; post, 42.0% [P < 0.0001]). An increase of ~50% was noted in long-term opioid users (from 22.1% to 32.1%). The use of monotherapy with a short-acting opioid decreased (pre, 35.1%; post, 32.5% [P < 0.0001]), while use of mixed opioids increased (pre, 13.7%; post, 19.1% [P < 0.0001]). Mean morphine-equivalent dose increased from pre- to post-SRE (9.1 vs 13.1 mg). Bisphosphonate and NSAID users decreased from before to after an SRE diagnosis (bisphosphonates, 40.2% vs 8.6%; NSAIDs, 26.7% vs 17.5% [both, P < 0.0001]). IMPLICATIONS: Long-term opioid use and dose were significantly increased after SRE development in MPC. The high percentage of patients not treated with an opioid or radiation potentially supports the need for additional treatment options for controlling pain if medically necessary and/or to prevent SREs.

RESUMO

The objective of this study was to examine indirect costs and workplace productivity loss (defined as an aggregate measure of absenteeism, short-term disability, and long-term disability days) associated with non-Hodgkin lymphoma (NHL) from a societal perspective in a commercially insured working-age United States population. The MarketScan(®) Commercial Claims and Encounters and Health and Productivity Management Databases (2007-2013) were used in this study, with controls matched 3:1 to NHL patients. In comparison to controls, NHL patients incurred significantly more workplace productivity loss (31.99 days; 95% CI: 25.24 days, 38.73 days; p < 0.001) and associated indirect costs ($6302.34; 95% CI: $4973.40, $7631.28; p < 0.001) in the 12-month post-diagnosis period when adjusting for covariates. NHL contributes significantly to losses in workplace productivity and higher associated indirect costs.

RESUMO

BACKGROUND: Approximately 40% of men diagnosed with metastatic prostate cancer experience one or more skeletal-related events (SREs), defined as a pathological fracture, spinal cord compression, or surgery or radiotherapy to the bone. Accurate assessment of their effect on survival, health care resource utilization (HCRU), and cost may elucidate the value of interventions to prevent SREs. MATERIALS AND METHODS: Men older than age 65 years with prostate cancer and bone metastasis diagnosed between 2004 and 2009 were identified from linked Surveillance Epidemiology and End Results-Medicare records. Hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk for death associated with SREs were calculated by using Cox regression. HCRU and costs (in 2013 U.S. dollars) were evaluated in a propensity score-matched cohort by using Poisson regression and Kaplan-Meier sample average estimators, respectively. RESULTS: Among 3,297 men with prostate cancer metastatic to bone, 40% experienced ≥1 SRE (median follow-up, 19 months). Compared with men who remained SRE-free, men with ≥1 SRE had a twofold higher risk for death (HR, 2.29; 95% CI, 2.09-2.51). Pathological fracture was associated with the highest risk for death (HR, 2.77; 95% CI, 2.38-3.23). Among men with ≥1 SRE, emergency department visits were twice as frequent (95% CI, 1.77-2.28) and hospitalizations were nearly four times as frequent (95% CI, 3.20-4.40). The attributable cost of ≥1 SRE was $21,191 (≥1 SRE: $72,454 [95% CI, $67,362-$76,958]; SRE-free: $51,263 [95% CI, $45,439-$56,100]). CONCLUSION: Among men with prostate cancer metastatic to bone, experiencing ≥1 SRE is associated with poorer survival, increased HCRU, and increased costs. These negative effects emphasize the importance of SRE prevention in this population.

RESUMO

GOALS: To evaluate hepatocellular carcinoma (HCC) surveillance rates among commercially insured patients, and evaluate factors associated with compliance with surveillance recommendations. BACKGROUND: Most HCC occurs in patients with cirrhosis. American Association for the Study of Liver Diseases and European Association for the Study of the Liver guidelines each recommend biannual HCC surveillance for cirrhotic patients to diagnose HCC at an early, curable stage. However, compliance with these guidelines in commercially insured patients is unknown. STUDY: We used the Truven Health Analytics databases from 2006 to 2010, using January 1, 2006 as the anchor date for evaluating outcomes. The primary outcome was continuous surveillance measure, defined as the proportion of time "up-to-date" with surveillance (PTUDS), with the 6-month interval immediately following each ultrasound categorized as "up-to-date." RESULTS: During a median follow-up of 22.9 (interquartile range, 16.3 to 33.9) months among 8916 cirrhotic patients, the mean PTUDS was 0.34 (SD, 0.29), and the median was 0.31 (interquartile range, 0.03 to 0.52). These values increased only modestly with inclusion of serum alpha-fetoprotein testing, contrast-enhanced abdominal computed tomographic scans or magnetic resonance imagings, and/or extension of up-to-date time to 12 months. Being diagnosed by a nongastroenterology provider and increasing age were significantly associated with decreased HCC surveillance (P<0.05), whereas a history of a hepatic decompensation event, presence of any component of the metabolic syndrome, and diagnosis of hepatitis B or hepatitis C were significantly associated with increased surveillance (P<0.05). However, even among patients with the most favorable characteristics, surveillance rates remained low. CONCLUSIONS: HCC surveillance rates in commercially insured at-risk patients remain poor despite formalized guidelines, highlighting the need to develop interventions to improve surveillance rates.

RESUMO

BACKGROUND & METHODS: The Child-Turcotte-Pugh (CTP) score is a widely used and validated predictor of long-term survival in cirrhosis. The CTP score is a composite of 5 subscores, 3 based on objective clinical laboratory values and 2 subjective variables quantifying the severity of ascites and hepatic encephalopathy. To date, no system to quantify CTP score from administrative databases has been validated. The Veterans Outcomes and Costs Associated with Liver Disease study is a multicenter collaborative study to evaluate the outcomes and costs of hepatocellular carcinoma in the U.S. Veterans Health Administration. We developed and validated an algorithm to calculate electronic CTP (eCTP) scores by using data from the Veterans Health Administration Corporate Data Warehouse. METHODS: Multiple algorithms for determining each CTP subscore from International Classification of Diseases version 9, Common Procedural Terminology, pharmacy, and laboratory data were devised and tested in 2 patient cohorts. For each cohort, 6 site investigators (Boston, Bronx, Brooklyn, Philadelphia, Minneapolis, and West Haven VA Medical Centers) were provided cases from which to determine validity of diagnosis, laboratory data, and clinical assessment of ascites and encephalopathy. The optimal algorithm (designated eCTP) was then applied to 30,840 cirrhotic patients alive in the first quarter of 2008 for whom 5-year overall and transplant-free survival data were available. The ability of the eCTP score and other disease severity scores (Charlson-Deyo index, Veterans Aging Cohort Study index, Model for End-Stage Liver Disease score, and Cirrhosis Comorbidity) to predict survival was then assessed by Cox proportional hazards regression. RESULTS: Spearman correlations for administrative and investigator validated laboratory data in the HCC and cirrhotic cohorts, respectively, were 0.85 and 0.92 for bilirubin, 0.92 and 0.87 for albumin, and 0.84 and 0.86 for international normalized ratio. In the HCC cohort, the overall eCTP score matched 96% of patients to within 1 point of the chart-validated CTP score (Spearman correlation, 0.81). In the cirrhosis cohort, 98% were matched to within 1 point of their actual CTP score (Spearman, 0.85). When applied to a cohort of 30,840 patients with cirrhosis, each unit change in eCTP was associated with 39% increase in the relative risk of death or transplantation. The Harrell C statistic for the eCTP (0.678) was numerically higher than those for other disease severity indices for predicting 5-year transplant-free survival. Adding other predictive models to the eCTP resulted in minimal differences in its predictive performance. CONCLUSION: We developed and validated an algorithm to extrapolate an eCTP score from data in a large administrative database with excellent correlation to actual CTP score on chart review. When applied to an administrative database, this algorithm is a highly useful predictor of survival when compared with multiple other published liver disease severity indices.

RESUMO

OBJECTIVES: To identify the pattern of the risk of death over long-term in unresectable hepatocellular carcinoma by determining the appropriate distribution to extrapolate overall survival and to assess the role of the Weibull distribution as the standard survival model in oncology. RESEARCH DESIGN AND METHODS: To select the appropriate distribution, three types of data sources have been analysed. Patient level data from two randomized controlled trials and published Kaplan-Meier curves from a systematic literature review provided short term follow-up data. They were supplemented with patient level data, with long-term follow-up from the Cancer Institute New South Wales, Australia. Published Kaplan-Meier curves were read in and a time-to-event dataset was created. Distributions were fitted to the data from the different sources separately. Their fit was assessed visually and compared using statistical criteria based on log-likelihood, the Akaike information criterion (AIC), and the Bayesian information criterion (BIC). RESULTS: Based on both published and patient-level, and both short- and long-term follow-up data, the Weibull distribution, used very often in cost-effectiveness models in oncology, does not seem to offer a good fit in hepatocellular carcinoma among the different survival models. The best fitting distribution appears to be the lognormal, with loglogistic as the second-best fitting function. Results were consistent between the different sources of data. CONCLUSIONS: In unresectable hepatocellular carcinoma, the Weibull model, which is often treated at the gold standard, does not appear to be appropriate based on different sources of data (two clinical trials, a retrospective database and published Kaplan-Meier curves). Lognormal distribution seems to be the most appropriate distribution for extrapolating overall survival.
