Abstract
Background: Cancer often co-occurs with other chronic conditions, which may result in polypharmacy. Polypharmacy is associated with adverse outcomes, including increased health service utilization. Objectives: This study examines the overall prevalence of polypharmacy (5 or more medications) among adults with cancer and multimorbidity, as well as the association of both minor polypharmacy (5-9 medications) and hyper-polypharmacy (10 or more medications) on high use of emergency room visits and hospitalizations, while controlling for age, sex, and type and stage of cancer. Methods: This retrospective longitudinal study used linked health administrative databases and included persons 18 years and older diagnosed with cancer between April 2010 and March 2013 in Ontario, Canada. Data on the number of health service utilizations at or above the 90th percentile (high users), was collected up to March 2014 and multivariate logistic regression was used to determine the impact of polypharmacy. Results: The prevalence of polypharmacy was 46% prior to cancer diagnosis, and 57% one year after diagnosis. Polypharmacy prior to and after cancer diagnosis increased with the level of multimorbidity, increasing age, but did not differ by sex. It was also highest in persons with lung cancer (52.4%) and those diagnosed with stage 4 cancer (51.3%). Minor polypharmacy increased the odds of being a high user of emergency rooms (1.16; 99% CI: 1.09-1.24) and hospitalizations (1.03; 0.98-1.09) and the odds of high use was greater with hyper-polypharmacy (1.41; 1.33-1.51) and (1.23; 1.17-1.29) respectively. Conclusion: Polypharmacy is highly prevalent and is associated with high health service utilization among adults with cancer and multimorbidity.

Serplulimab Plus Chemotherapy vs Chemotherapy for Treatment of US and Chinese Patients with Extensive-Stage Small-Cell Lung Cancer: A Cost-Effectiveness Analysis to Inform Drug Pricing. BioDrugs 2023; 37:421-432. [PMID: 36840914 DOI: 10.1007/s40259-023-00586-6] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/09/2023] [Indexed: 02/26/2023]
Abstract
BACKGROUND Serplulimab is a potential valuable therapy, while patients, physicians, and decision-makers are uncertain about the cost-effectiveness of this novel drug and its corresponding reasonable price. This study aimed to simulate the price at which serplulimab was cost-effective as first-line therapy for United States (US) and Chinese extensive-stage small-cell lung cancer (ES-SCLC) patients. METHODS In this economic evaluation, a partitioned survival model was constructed from the perspective of US and Chinese payers. Baseline characteristics of patients and critical clinical data were obtained from ASTRUM-005. Costs and utilities were collected from open-access databases and published literature. Cumulative costs (in US dollars), life years, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) were measured and compared. Price simulation was conducted to inform the pricing strategy at the given willingness-to-pay (WTP) threshold. The robustness of the model was assessed via sensitivity analyses and scenario analyses; subgroup analyses were also included. RESULTS Base-case analysis indicated that serplulimab ($818.16/100 mg) would be cost-effective in the US at the WTP threshold of $150,000, with improved effectiveness of 0.61 QALYs and an additional cost of $64,918 (ICER $106,757). Serplulimab ($818.16/100 mg, patient assistance program considered) was cost-effective in China, with improved effectiveness of 0.58 QALYs and an increased overall cost of $19,369 (ICER $33,392). The price simulation results indicated that serplulimab was favored in the US when the price was less than $762.11/100 mg and $1261.57/100 mg at the WTP threshold of $100,000 and $150,000, respectively; it was cost-effective at the WTP threshold of $38,184 when the price was less than $373.37/100 mg in China. Sensitivity analyses revealed that the above results were stable. Subgroup analysis results indicated an overall trend for subgroups with better survival advantages to have a higher probability of cost-effectiveness, despite serplulimab not being cost-effective in some subgroups. CONCLUSIONS Serplulimab might be a valuable and cost-effective therapy in both the US and China. The evidence-based pricing strategy provided by this study could benefit decision-makers in making optimal decisions and clinicians in general clinical practice. More evidence about the budget impact and affordability for patients is needed.

Treatment patterns for advanced non-small cell lung cancer in the US: A systematic review of observational studies. Cancer Treat Res Commun 2022; 33:100648. [PMID: 36270164 DOI: 10.1016/j.ctarc.2022.100648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 10/10/2022] [Accepted: 10/11/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND The advent of immunotherapies (I-O) and targeted therapies has transformed the treatment landscape in advanced non-small cell lung cancer (NSCLC). However, adoption of new treatment guidelines and evolving treatment patterns in clinical practice are largely unknown. The aim of this systematic literature review (SLR) was to capture real-world first-line treatment patterns in advanced (staged IIIB-IV) or recurrent NSCLC patients in the US. METHODS Electronic databases were systematically searched for observational studies published 2012-2020 that reported on adult patients receiving first-line therapy for advanced NSCLC. Included studies were reviewed and treatment patterns were summarized descriptively. RESULTS Eighteen studies were included. Platinum-doublet (PD) chemotherapy and unspecified chemotherapy regimens were the most commonly used first-line treatments (up to 71% and 96%, respectively). Chemotherapy as monotherapy was mainly utilized in patients ≥65 years. While chemotherapy use was continuously high, I-O became the preferred front-line treatment in 2018 (32.9%). I-O monotherapy was more prevalent among patients with PD-L1 ≥50%, compared to patients with lower levels. First-line use of tyrosine kinase inhibitors and bevacizumab-based therapies was common in 2010 (33.4% and 21.7%, respectively), but gradually declined to <1% in 2018. CONCLUSION Consistent with the evolving first-line NSCLC treatment landscape in the US, this SLR captures the increasing use of I-O in recent years. While the brief lag in I-O use from the time of authorization may be attributable to an initial resistance to treatment adoption or publication delays, continued use of chemotherapy regimens may reflect an unmet treatment need, which warrants further research.

Abstract
OBJECTIVES To evaluate an algorithm developed for identifying non-small cell lung cancer (NSCLC) candidates among patients with lung cancer with a diagnosis International Classification of Diseases: ninth revision (ICD-9) 162.x code in administrative databases. Algorithm could then be applied for identifying the NSCLC population in order to assess the appropriateness and quality of care of the NSCLC care pathway. DESIGN Algorithm discrimination capacity to select both NSCLC or non-NSCLC was carried out on a sample for which electronic health record (EHR) diagnosis was available. A bivariate frequency distribution and other measures were used to evaluate algorithm's performances. Associations between possible factors potentially affecting algorithm accuracy were investigated. SETTING Administrative databases used in a specific geographical area of Emilia-Romagna region, Italy. PARTICIPANTS Algorithm was carried out on patients aged >18 years, with a lung cancer diagnosis from January to December 2017 and resident in Emilia-Romagna region who have been hospitalised at IRST or in one of the hospitals placed in the Forlì-Cesena area and for which EHR diagnosis data were available. OUTCOME MEASURES Overall accuracy, positive (PPV) and negative (NPV) predictive values, sensitivity and specificity, positive and negative likelihood ratios and diagnostic OR were calculated. RESULTS A total of 430 patients were identified as lung cancer cases based on ICD-9 diagnosis. Focusing on the total incident cases (n=314), the algorithm had an overall accuracy of 82.8% with a sensitivity of 88.8%. The analysis confirmed a high level of PPV (90.2%), but lower specificity (53.7%) and NPV (50%). Higher length of stay seemed to be associated with a correct classification. Hospitalisation regimen and a supply of antiblastic therapy seemed to increase the level of PPV. CONCLUSION The algorithm demonstrated a strong validity for identifying NSCLC among patients with lung cancer in hospital administrative databases and can be used to investigate the quality of cancer care for this population. TRIAL REGISTRATION NUMBER NCT04676321.

First-line treatment for lung cancer among Japanese older patients: A real-world analysis of hospital-based cancer registry data. PLoS One 2021; 16:e0257489. [PMID: 34543332 PMCID: PMC8452055 DOI: 10.1371/journal.pone.0257489] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Accepted: 09/03/2021] [Indexed: 12/02/2022] Open
Abstract
Aging of the population has led to an increase in the prevalence of cancer among older adults. In Japan, single agent chemotherapy was recommended for advanced non-small cell lung cancer (NSCLC) for those, who were aged ≥75 years, while the Western guidelines did not recommend a specific regimen. In clinical practice, physicians are required to decide the treatment based on a lack of enough evidence. This study aimed to examine the prescribing patterns of first-line chemotherapy according to age in the real-world practice. Data from the survey database of Diagnostic Procedure Combination and hospital-based cancer registries of designated cancer centers nationwide were used. The first-line chemotherapy regimens among 9,737 patients who were diagnosed with advanced lung cancer between January and December 2013, were identified and compared based on age. We found that the proportion of patients receiving chemotherapy decreased with age; 80.0%, 70.4%, 50.6%, and 30.2% of patients aged 70–74, 75–79, 80–84, and ≥ 85 years, respectively, received chemotherapy. Among them, platinum doublets were prescribed for 62.7% of the patients who were aged ≥ 70 years, and 60.7% of the patients who were aged ≥ 75 years with no driver mutations in NSCLC; only 37.6% of them received single agents. Patients who were aged ≥ 80 years also preferred platinum doublets (35.6%). Carboplatin was commonly prescribed in all age groups; only 28.4% of those receiving platinum doublets selected cisplatin. In this study, platinum doublets were identified as the most commonly prescribed regimen in those who were aged ≥ 70 years. Despite recommendations of Japanese guidelines for NSCLC, 60.7% of those who were aged ≥75 years received platinum doublets. Additionally, patients who were aged ≥ 80 years also received systemic chemotherapy, including platinum doublets; age did not solely influence regimen selection.

Abstract
AIM Systemic therapies for lung cancer are rapidly evolving. This study aimed to describe lung cancer treatment patterns in New South Wales, Australia, prior to the introduction of immunotherapy and latest-generation targeted therapies. METHODS Systemic therapy utilization and treatment-related factors were examined for participants in the New South Wales 45 and Up Study with incident lung cancer ascertained by record linkage to the New South Wales Cancer Registry (2006-2013). Systemic therapy receipt to June 2016 was determined using medical and pharmaceutical claims data from Services Australia, and in-patient hospital records. Factors related to treatment were identified using competing risks regressions. RESULTS A total of 1,116 lung cancer cases were identified with a mean age at diagnosis of 72 years and median survival of 10.6 months. Systemic therapy was received by 45% of cases. Among 400 cases with metastatic non-small cell lung cancer, 51% and 28% received first- and second-line systemic therapy, respectively. Among 112 diagnosed with small-cell lung cancer, 79% and 29% received first- and second-line systemic therapy. The incidence of systemic therapy was lower for participants with indicators of poor performance status, lower educational attainment, and those who lived in areas of socioeconomic disadvantage; and was higher for participants with small-cell lung cancer histology or higher body mass index. CONCLUSION This population-based Australian study identified patterns of systemic therapy use for lung cancer, particularly small-cell lung cancer. Despite a universal healthcare system, the analysis revealed socioeconomic disparities in health service utilization and relatively low utilization of systemic therapy overall.

Economic burden of lung cancer in Turkey: a cost of illness study from payer perspective. HEALTH ECONOMICS REVIEW 2021; 11:22. [PMID: 34173876 PMCID: PMC8233643 DOI: 10.1186/s13561-021-00322-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Accepted: 06/11/2021] [Indexed: 05/28/2023]
Abstract
BACKGROUND This study was designed to estimate economic burden of lung cancer in Turkey from payer perspective based on expert panel opinion on practice patterns in clinical practice. METHODS In this cost of illness study, direct medical cost was calculated based on cost items related to outpatient visits, laboratory and radiological tests, hospitalizations/interventions, drug treatment, adverse events and metastasis. Indirect cost was calculated based on lost productivity due to early retirement, morbidity and premature death resulting from the illness, the value of lost productivity due to time spent by family caregivers and cost of formal caregivers. RESULTS Cost analysis revealed the total per patient annual direct medical cost for small cell lung cancer to be €8772), for non-small-cell lung cancer to be €10,167. Total annual direct medical cost was €497.9 million, total annual indirect medical cost was €1.1 billion and total economic burden of lung cancer was €1.6 billion. Hospitalization/interventions (41%) and indirect costs (68.6%) were the major cost drivers for total direct costs and the overall economic burden of lung cancer, respectively. CONCLUSIONS Our findings indicate per patient direct medical costs of small cell lung cancer and non-small-cell lung cancer to be substantial and comparable, indicating the substantial economic burden of lung cancer in terms of both direct and indirect costs. Our findings indicate that hospitalization/interventions cost item and indirect costs were the major cost drivers for total direct costs and the overall economic burden of lung cancer, respectively. Our findings emphasize the potential role of improved cancer prevention and early diagnosis strategies, by enabling cost savings related to drug treatment and metastasis management cost items, in sustainability of cancer treatments.

Abstract
Background: Real-world data are lacking on patients with small-cell lung cancer (SCLC) with extensive-stage SCLC (eSCLC) and poor performance status (PS). Patients & methods: Eligible patients diagnosed with eSCLC between 1 January 2008 and 31 December 2017 were included in this retrospective, observational study. Results: The study included 406 patients, with 14.3% impaired PS. Progression-free survival and overall survival were not significantly different between impaired (Eastern Cooperative Oncology Group ≥2) and not impaired patients (median, 4.5 vs 5.3 months, and 7.2 vs 8.4 months, respectively). Impaired patients used more supportive care drugs (mean, 3.0 vs 2.0; p = 0.033). Conclusion: Effectiveness outcomes among patients with and without impaired PS did not differ in the real-world setting. Progression-free survival and overall survival were similar to data from clinical trials.

Abstract
Although physicians rely on clinical trial data to guide cancer treatment decisions, patient characteristics and outcomes often differ between real-world and clinical trial populations. We analyzed retrospective clinical data collected from a prior authorization (PA) tool linked with payer claims data to describe outcomes of first-line treatment for metastatic non-small cell lung cancer among 2,108 patients. Duration of therapy was shorter than observed in clinical trials. Healthcare costs and hospitalizations varied substantially by regimen. PA clinical data linked with administrative claims enable head-to-head comparisons of contemporary cancer treatments used in routine clinical practice, which are not available from clinical trials.

Abstract
INTRODUCTION Most cases of small cell lung cancer (SCLC) are diagnosed at an advanced stage. The objective of this study was to investigate patient characteristics, survival, chemotherapy treatments, and health care use after a diagnosis of advanced SCLC in subjects enrolled in a health system network. METHODS This was a retrospective cohort study of patients aged ≥ 18 years who either were diagnosed with stage III/IV SCLC or who progressed to advanced SCLC during the study period (2005-2015). Patients identified from the Indiana State Cancer Registry and the Indiana Network for Patient Care were followed from their advanced diagnosis index date until the earliest date of the last visit, death, or the end of the study period. Patient characteristics, survival, chemotherapy regimens, associated health care visits, and durations of treatment were reported. Time-to-event analyses were performed using the Kaplan-Meier method. RESULTS A total of 498 patients with advanced SCLC were identified, of whom 429 were newly diagnosed with advanced disease and 69 progressed to advanced disease during the study period. Median survival from the index diagnosis date was 13.2 months. First-line (1L) chemotherapy was received by 464 (93.2%) patients, most commonly carboplatin/etoposide, received by 213 (45.9%) patients, followed by cisplatin/etoposide (20.7%). Ninety-five (20.5%) patients progressed to second-line (2L) chemotherapy, where topotecan monotherapy (20.0%) was the most common regimen, followed by carboplatin/etoposide (14.7%). Median survival was 10.1 months from 1L initiation and 7.7 months from 2L initiation. CONCLUSION Patients in a regional health system network diagnosed with advanced SCLC were treated with chemotherapy regimens similar to those in earlier reports based on SEER-Medicare data. Survival of patients with advanced SCLC was poor, illustrating the lack of progress over several decades in the treatment of this lethal disease and highlighting the need for improved treatments.

Abstract
OBJECTIVES The effectiveness and costs of new treatments should be assessed in relation to existing practice. We describe treatments, survival and costs for advanced or metastatic small cell lung cancer (SCLC) patients receiving systemic therapy in the period preceding the introduction of immunotherapies. MATERIALS AND METHODS This was a retrospective cohort study of patients aged ≥65 years, identified using linked Surveillance, Epidemiology, and End Results and Medicare databases. Individuals with a new primary diagnosis of SCLC between January 2007 and December 2013 were followed until December 2014. Chemotherapy treatments, health care visits and costs (in 2016 USD), and survival were determined by line of therapy. RESULTS A total of 11 812 patients were identified with SCLC. First-line (1L) chemotherapy was received by 6509 (55.1%) patients, most (93.2%) with carboplatin- (71.0%) or cisplatin- (22.2%) based therapies, typically combined with etoposide (79.2%). Second- (2L) and third- (3L) line chemotherapies were received by 2238 (18.9%) and 679 (5.7%) patients, of which 48.4% and 30.9%, respectively, were platinum-based. The median durations of 1L, 2L, and 3L carboplatin-based therapies were 5.9, 4.8, and 5.4 months, respectively, and the corresponding durations of cisplatin-based therapies were 5.3, 4.2, and 5.3 months. During 1L, 2L, and 3L chemotherapies, patients averaged 8.2, 7.4, and 7.3 health care visits per month, respectively, and incurred total mean health care costs of $60 223, $42 636, and $35 903 per patient, respectively. Median survival from the start of 1L, 2L, and 3L chemotherapy was 9.2, 6.0, and 5.7 months, respectively. CONCLUSION First-line chemotherapy was primarily platinum-based, and a plethora of different regimens was used for 2L and 3L chemotherapies. Median survival from the start of 1L chemotherapy was 9 months, with an associated health care cost of $60 000. These data highlight an unmet medical need among SCLC patients receiving systemic therapy.

Impact of thoracic radiation therapy after chemotherapy on survival in extensive-stage small cell lung cancer: A propensity score-matched analysis. Thorac Cancer 2019; 10:799-806. [PMID: 30779334 PMCID: PMC6449270 DOI: 10.1111/1759-7714.13001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2018] [Revised: 01/13/2019] [Accepted: 01/13/2019] [Indexed: 11/27/2022] Open
Abstract
Background The role of thoracic radiation therapy (TRT) after chemotherapy (CHT) in extensive‐stage small cell lung cancer (ES‐SCLC) has not been well defined. We investigated whether intensity‐modulated radiotherapy (IMRT) improves outcomes in ES‐SCLC after CHT compared to CHT alone. Methods A total of 292 patients who reached a complete response (CR), partial response (PR), or stable disease (SD) after CHT were assigned into groups: CHT + TRT and CHT alone. Propensity score matching was used to balance patient groups (n = 72 each). Results The five‐year overall survival (OS: 12.3% vs. 3.6%; P < 0.001) and progression‐free survival (PFS: 3.2% vs. 1.7%; P = 0.006) rates were significantly higher in the CHT + TRT group. This data was confirmed in the matched samples (5‐year OS: 10.5% vs. 1.6%, P < 0.001; PFS: 4.3% vs. 0.0%, P = 0.023). The overall (P = 0.002) and locoregional (P < 0.001) recurrence rates in the CHT + TRT group were significantly lower than in the CHT group. Univariate analysis showed that response evaluation after CHT and TRT were significant prognostic factors of OS. Multivariate analyses revealed that N Stage 0–1 (P = 0.02), > 6 cycles of CHT (P = 0.042), CR + PR after CHT (P < 0.001), and TRT (P < 0.001) were independently associated with longer OS compared to CHT alone. Conclusion TRT using IMRT is strongly correlated with improved OS and PFS in ES‐SCLC patients reaching CR, PR or SD after CHT. A multicenter, randomized phase III clinical trial is needed to confirm these findings.

Abstract
AIM A comparison of conventional pairwise propensity score matching (PSM) and generalized PSM method was applied to the comparative effectiveness of multiple treatment options for lung cancer. MATERIALS & METHODS Deidentified data were analyzed. Covariate balances between compared treatments were assessed before and after PSM. Cox proportional hazards regression compared overall survival after PSM. RESULTS & CONCLUSION The generalized PSM analyses were able to retain 61.2% of patients, while the conventional PSM analyses were able to match from 24.1 to 77.1% of patients from each treatment comparison. The generalized PSM achieved statistical significance (p < 0.05) in 8/10 comparisons, whereas conventional pairwise PSM achieved 1/10. The noted differences arose from different matched patient samples and the size of the samples.

Real-World Treatment Patterns, Overall Survival, and Occurrence and Costs of Adverse Events Associated With Second-Line Therapies for Medicare Patients With Advanced Non-Small-Cell Lung Cancer. Clin Lung Cancer 2018; 19:e783-e799.

Abstract
INTRODUCTION Real-world data on current treatment practices for non-small-cell lung cancer (NSCLC) are needed to understand the place in therapy and potential economic impact of newer therapies. PATIENTS AND METHODS This retrospective cohort study identified patients ≥ 65 years old in the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database with first-time diagnosis of stage IIIB/IV NSCLC from 2007-2011 who received second-line therapy after first-line platinum-based chemotherapy from 2007 through mid-2013. Second-line regimens, health care resource use, adverse events (AEs), and associated costs were analyzed descriptively. Overall survival was determined by Kaplan-Meier test. Costs were adjusted to 2013 US dollars. RESULTS We identified 4033 patients with advanced NSCLC who received second-line therapy (47% of those who received first-line platinum-based chemotherapy). Mean (SD) age was 73 (5) years, 2246 (56%) were male; 1134 (28%) and 2899 (72%) had squamous and nonsquamous NSCLC, respectively. The 4 most common second-line regimens were pemetrexed (22%), docetaxel (12%), carboplatin/paclitaxel (11%), and gemcitabine (7%). Median overall survival from second-line therapy initiation was 7.3 months (95% confidence interval, 7.0-7.7). Dyspnea and anemia were the most common AEs of interest, affecting 29% and 26% of patients, respectively; atypical pneumonia was associated with the highest AE-related costs (mean, $5339). The mean total per-patient-per-month cost was $10,885; AE-related per-patient-per-month costs totaled $1036 (10%). Costs were highest for pemetrexed-treated patients. CONCLUSION These real-world data illustrate the variety of second-line regimens, poor prognosis, and high cost of second-line chemotherapy for patients with advanced NSCLC treated before the approval of immunotherapies for these patients.

Abstract
BACKGROUND Small cell lung cancer (SCLC), the most aggressive form of lung carcinoma, represents approximately 15% of all lung cancers; however, the economic and healthcare burden of SCLC is not well-defined. OBJECTIVE The aim of this study was to explore the impact of SCLC on healthcare costs through a systematic literature review (SLR). METHODS Using the OVID search engine, the SLR was conducted in PubMed, MEDLINE In-Process, EMBASE, EconLIT and the National Health Service Economic Evaluation Database (NHS EED). Searches were limited to studies published between January 2005 and 24 February 2016, and excluded preclinical studies. Additional internet-based searches were conducted. In total, 229 abstracts were retrieved and systematically screened for eligibility, with 17 publications retained. RESULTS The majority of publications provided data on limited and extensive disease of SCLC. The reported burden was categorised as direct costs and indirect costs, with the majority of the publications (n = 16) reporting on direct costs and one reporting on both direct and indirect costs. The only indirect costs reported for SCLC were lost productivity (premature mortality costs) and caregiver burden. Chemotherapy, diagnostic costs and treatment costs were identified as significant costs when managing SCLC patients, including the associated treatment costs such as hospitalisation, nurse visits, emergency room visits, follow-up appointments and outpatient care. CONCLUSIONS SCLC and its treatment have a substantial impact on costs. The scarcity and heterogeneity of economic cost data negated meaningful cost comparison, highlighting the need for further research. Capturing the economic burden of SCLC may help patients and clinicians make informed treatment choices and improve SCLC management.

Real-World Use and Outcomes of ALK-Positive Crizotinib-Treated Metastatic NSCLC in US Community Oncology Practices: A Retrospective Observational Study. J Clin Med 2018; 7:jcm7060129. [PMID: 29844259 PMCID: PMC6025021 DOI: 10.3390/jcm7060129] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Accepted: 05/15/2018] [Indexed: 12/20/2022] Open
Abstract
Introduction: Around 3–5% of non-small cell lung cancers (NSCLC) are ALK-positive. Crizotinib was the first approved ALK inhibitor from clinical trials. However, there are less data on the utilization and patient outcomes associated with crizotinib in real-world clinical practice. Methods: This was a retrospective, observational study of adult crizotinib-treated ALK-positive metastatic NSCLC patients who received treatment between 1 September 2011 and 31 October 2014, with follow up through 31 December 2015. Data were obtained via programmatic queries of the US Oncology Network/McKesson Specialty Health electronic health record database, supplemented with chart abstraction. Overall survival (OS) and time to treatment failure (TTF) were estimated from crizotinib initiation using the Kaplan–Meier (KM) method. Results: Of the n = 199 ALK-positive crizotinib-treated patients meeting eligibility criteria, crizotinib was prescribed as first line (1 L) in n = 123 (61.8%). The majority (88.9%) had confirmed adenocarcinoma histology and 32.2% had brain metastases at initial diagnosis. Median age at crizotinib initiation was 60.2 years (range 27.1–88.2); 54.8% were never smokers, 33.7% were former smokers. Treatment of 250 mg, twice daily, was most commonly prescribed (89.5%) with the dose unchanged from an initial dose in 79.4% of patients. The primary discontinuation reason was progression (n = 91, 58.7%). Patients (3.2%) were identified as discontinuing crizotinib as a result of treatment-related toxicity. With median follow-up time of 13.0 months (min–max = 0.03–46.6), median OS from crizotinib initiation was 33.8 months (95% CI = 24.3–38.8). Median TTF was 10.4 months. Conclusions: Crizotinib usage evaluated within the real-world setting is consistent with prior phase III clinical trial data, and illustrates the real-world effectiveness of crizotinib.

Abstract
OBJECTIVES To assess the accuracy of International Classification of Diseases 9th Revision-Clinical Modification (ICD-9-CM) codes in identifying subjects with lung cancer. DESIGN A cross-sectional diagnostic accuracy study comparing ICD-9-CM 162.x code (index test) in primary position with medical chart (reference standard). Case ascertainment was based on the presence of a primary nodular lesion in the lung and cytological or histological documentation of cancer from a primary or metastatic site. SETTING Three operative units: administrative databases from Umbria Region (890 000 residents), ASL Napoli 3 Sud (NA) (1 170 000 residents) and Friuli Venezia Giulia (FVG) Region (1 227 000 residents). PARTICIPANTS Incident subjects with lung cancer (n=386) diagnosed in primary position between 2012 and 2014 and a population of non-cases (n=280). OUTCOME MEASURES Sensitivity, specificity and positive predictive value (PPV) for 162.x code. RESULTS 130 cases and 94 non-cases were randomly selected from each database and the corresponding medical charts were reviewed. Most of the diagnoses for lung cancer were performed in medical departments.True positive rates were high for all the three units. Sensitivity was 99% (95% CI 95% to 100%) for Umbria, 97% (95% CI 91% to 100%) for NA, and 99% (95% CI 95% to 100%) for FVG. The false positive rates were 24%, 37% and 23% for Umbria, NA and FVG, respectively. PPVs were 79% (73% to 83%)%) for Umbria, 58% (53% to 63%)%) for NA and 79% (73% to 84%)%) for FVG. CONCLUSIONS Case ascertainment for lung cancer based on imaging or endoscopy associated with histological examination yielded an excellent sensitivity in all the three administrative databases. PPV was moderate for Umbria and FVG but lower for NA.

Abstract
Objective: To assess the validity of a treatments- and tests-based Case-Finding Algorithm for identifying patients with non-small cell lung cancer (NSCLC) from claims databases. Data sources: Primary data from the HealthCore Integrated Research Environment (HIRE)-Oncology database and the HealthCore Integrated Research Database (HIRD) were collected between June 1, 2014, and October 31, 2015. Study design: A comparative statistical evaluation using receiver operating characteristic (ROC) curve analysis and other validity measures was used to validate the NSCLC Case-Finding Algorithm vs. a control algorithm. Data collection: Patients with lung cancer were identified based on diagnosis and pathology classifications as NSCLC or small-cell lung cancer. Records from identified patients were linked to claims data from Anthem health plans. Three-month pre-index and post-index data were included. Principal findings: The NSCLC Case-Finding Algorithm had an area under the curve (AUC) of 0.88 compared with 0.53 in the control (p < 0.0001). Promising diagnostic accuracy was observed for the NSCLC Case-Finding Algorithm based on sensitivity (94.8%), specificity (81.1%), positive predictive value (PPV) (95.3%), negative predictive value (NPV) (79.6%), accuracy (92.1%), and diagnostic odds ratio (DOR) (78.8). Conclusions: The NSCLC Case-Finding Algorithm demonstrated strong validity for distinguishing patients with NSCLC from those with SCLC in claims data records and can be used for research into NSCLC populations.

Receipt of thoracic radiation therapy and radiotherapy dose are correlated with outcomes in a retrospective study of three hundred and six patients with extensive stage small-cell lung cancer. Radiother Oncol 2017; 125:331-337. [PMID: 29079309 DOI: 10.1016/j.radonc.2017.10.005] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2017] [Revised: 09/06/2017] [Accepted: 10/03/2017] [Indexed: 01/22/2023]
Abstract
BACKGROUND The importance of the thoracic radiation therapy (TRT) dose has not been clearly defined in extensive stage small-cell lung cancer (ES-SCLC) and it is unclear whether improved TRT dose translates into a survival benefit. METHODS 306 patients with ES-SCLC were retrospectively reviewed, of which 170 received IMRT/CRT fractionation RT after ChT, and 136 received chemotherapy (ChT) alone. We adopted the time-adjusted BED (tBED) for effective dose fractionation calculation. Due to the nonrandomized nature of this study, we compared the ChT+RT with ChT groups that matched on possible confounding variables. RESULTS Patients achieved 2-year OS, PFS and LC rates of 19.7%, 10.7% and 28.4%, respectively. After propensity score matching, (113 cases for each group), the rates of OS, PFS and LC at 2 years were 21.4%, 7.7% and 34.5% for ChT+TRT, and 10.3% (p<0.001), 4.6% (p<0.001) and 6.3% for ChT only (p<0.001), respectively. Among propensity score matching patients, 56 cases for each group received the high dose (tBED>50 Gy) TRT and received low dose (tBED≤50 Gy) TRT. Two-year OS, PFS and LC rates were 32.3%, 15.3% and 47.1% for the high dose compared with 17.0% (p<0.001), 12.9% (p=0.097) and 34.7% (p=0.029) for low dose radiotherapy. CONCLUSIONS TRT added to ChT improved ES-SCLC patient OS. High dose TRT improved OS over lower doses. Our results suggest that high-dose thoracic radiation therapy may be a reasonable consideration in select patients with ES-SCLC.

Cost-Effectiveness of Thoracic Radiation Therapy for Extensive-Stage Small Cell Lung Cancer Using Evidence From the Chest Radiotherapy Extensive-Stage Small Cell Lung Cancer Trial (CREST). Int J Radiat Oncol Biol Phys 2017; 100:97-106. [PMID: 29029885 DOI: 10.1016/j.ijrobp.2017.08.041] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Revised: 08/10/2017] [Accepted: 08/28/2017] [Indexed: 12/11/2022]
Abstract
PURPOSE The Chest Radiotherapy Extensive-Stage Small Cell Lung Cancer Trial (CREST) showed that adding thoracic radiation therapy (TRT) to the standard treatment (ST) paradigm of chemotherapy and prophylactic cranial irradiation improves overall survival and progression-free survival (PFS) in patients with extensive-stage small cell lung cancer (ES-SCLC). We evaluated the cost-effectiveness of adding TRT to ST in ES-SCLC patients. METHODS AND MATERIALS A cost-utility analysis was performed comparing TRT plus ST versus ST alone. The base-case time horizon was 24 months, consistent with the maximum PFS reported in the CREST. Overall survival was partitioned into 2 health states: PFS and postprogression survival. The proportion of patients in each health state over time was estimated by fitting parametric probability distributions to the CREST survival data. Costs were from a US health care payer perspective, and utilities were derived from the literature. Incremental cost-effectiveness ratios (ICERs) were calculated per quality-adjusted life-year (QALY) using a 3% discount rate. Sensitivity analyses addressed uncertainty in key variables. RESULTS In the base-case analysis, adding TRT to ST was both cost saving and more effective, thereby strongly dominating ST alone. At willingness-to-pay thresholds of $50,000/QALY, $100,000/QALY, and $200,000/QALY, TRT was preferred 68%, 81%, and 96% of the time, respectively. In the lifetime scenario analysis, the TRT ICER increased to $194,726/QALY. CONCLUSIONS By use of the actual follow-up interval reported in the CREST, adding TRT to ST strongly dominates a strategy of ST alone in ES-SCLC patients. Since the long-term survival benefit of TRT is small relative to ongoing costs of progressive metastatic disease, we estimate less favorable ICERs for TRT over a lifetime horizon.

[PMID: 28710943 PMCID: PMC5572775 DOI: 10.1016/j.canep.2017.07.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2017] [Revised: 06/24/2017] [Accepted: 07/03/2017] [Indexed: 01/10/2023]
Abstract
BACKGROUND The experiences of patients with recurrent cancer are assumed to reflect those of patients with de novo stage IV disease; yet, little is truly known because most registries lack recurrence status. Using two databases with excellent recurrence and death information, we examined determinants of survival duration after recurrence of breast (BC), colorectal (CRC), and lung cancers (LC). METHODS Recurrence status was abstracted from the medical records of patients who participated in the Cancer Care Outcomes Research and Surveillance study and who received care at two Cancer Research Network sites-the Colorado and Northwest regions of Kaiser Permanente. The analysis included 1653 patients who developed recurrence after completing definitive therapy for stages I-III cancer. Multivariable modeling identified independent determinants of survival duration after recurrence, controlling for other factors. RESULTS Through 60 months' average follow-up, survival after recurrence for BC, CRC, and LC were 28.4, 23.1 and 16.1 months, respectively. Several factors were independently associated with shorter survival for all three cancers, including higher initial stage (III vs. I: BC -9.9 months; CRC -6.9 months; LC -7.4 months; P≤0.01). Factors associated with shorter survival for selected cancers included: distant/regional recurrence for BC and CRC; current/former smoker for LC; high grade for CRC; and <4-year time-to-recurrence for BC. CONCLUSIONS Initial stage predicts survival duration after recurrence, whereas time-to-recurrence usually does not. The impact of biologic characteristics (e.g., grade, hormone-receptor status) on survival duration after recurrence needs further study. Predictors of survival duration after recurrence may help facilitate patient decision-making.

The Role of 18F-FDG PET/CT on Staging and Prognosis in Patients with Small Cell Lung Cancer. Eur Radiol 2015; 26:3155-61. [PMID: 26685851 DOI: 10.1007/s00330-015-4132-2] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2015] [Revised: 11/05/2015] [Accepted: 11/23/2015] [Indexed: 02/06/2023]
Abstract
BACKGROUND We evaluated 18F-FDG PET/CT in small cell lung cancer (SCLC) staging and assessed metabolic (SUVmax, MTV and TLG) and morphologic (CTvol) variables as predictors for overall survival (OS) and progression-free survival (PFS). METHODS Patients with newly diagnosed, histopathology-confirmed SCLC, who underwent 18F-FDG PET/CT were evaluated. A Cox proportional hazard model was used to determine the association between the primary tumour SUVmax, MTV, TLG and CTvol with OS and PFS. Similar evaluations were performed when hilar/mediastinal lymphadenopathy was included [total SUVmax (TSUVmax), total MTV (TMTV) and total TLG (TTLG)]. RESULTS 55 patients were included. 18F-FDG PET/CT changed staging in 6/55 (10.9%) patients who were upstaged to extensive disease. TTLG (>443.8) was a significant variable for OS with HR=2.1 (CI 1.14-3.871, p=0.017). Patients with TTLG>443.8 had a median OS of 13.4 months compared to 25.7 months in patients with TTLG<443.8 (p=0.018). TMTV (>72.4) was significant for PFS with HR=2.3 (CI 1.11-4.8, p=0.025). A median PFS of 12.1 and 26.2 months was found with TMTV greater and less than 72.4, respectively (p=0.005). CONCLUSIONS 18F-FDG PET/CT improved staging of patients with SCLC, and TTLG and TMTV can be used as prognostic variables for OS and PFS, respectively. KEY POINTS • Identifying variables that predict the prognosis of patients with SCLC is important. • 18F-FDG PET/CT influences staging of patients with SCLC. • Metabolic parameters could be used as predictors for PFS and OS.

Adherence to granulocyte-colony stimulating factor (G-CSF) guidelines to reduce the incidence of febrile neutropenia after chemotherapy--a representative sample survey in Germany. Support Care Cancer 2015; 24:367-376. [PMID: 26081593 DOI: 10.1007/s00520-015-2779-5] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Accepted: 05/17/2015] [Indexed: 11/30/2022]
Abstract
PURPOSE Febrile neutropenia (FN) after chemotherapy increases complications, morbidity, risk of death, reduction of dose delivery and impairs quality of life. Primary granulocyte-colony stimulating factor (G-CSF) prophylaxis after chemotherapy is recommended in the guideline (GL) if the risk of FN is high (≥20%) or intermediate (≥10-20%) with additional risk factors. This study evaluated the implementation of G-CSF GL. PATIENTS AND METHODS Sample size of the survey was calculated at 2% of the incidences of malignant lymphoma, breast cancer, and lung cancer in Germany in 2006. Patients were documented retrospectively over three to nine cycles of chemotherapy and FN risk ≥10%. Professional physician profiles were analyzed by classification and regression tree analysis (CART). RESULTS One hundred ninety-five hematologists-oncologists and pulmonologists and gynecologists specialized in oncology documented data of 666 lung cancer patients, 286 malignant lymphoma patients, and 976 breast cancer patients, with 7805 chemotherapy cycles; 85.1% of physicians claimed adhering to G-CSF GL. Adherence to GL in all high-FN-risk chemotherapy cycles was 15.4% in lung cancer, 84.5% in malignant lymphoma, and 85.6% in breast cancer, and in all intermediate-FN-risk chemotherapy cycles, lung cancer it was 38.8%, malignant lymphoma it was 59.4%, and breast cancer it was 49.3%. G-CSF was overused without additional patient risk factors in 7.2% lung cancer cycles, 16.8% malignant lymphoma cycles, and 17.6% breast cancer cycles. The CART analysis split pulmonologists and other specialists, with the latter adhering more to GL. Pulmonologists, trained less than 22.5 years, adhered better to GL, as did also gynecologists or hematologists-oncologists with professional experience less than 8.1 years. CONCLUSIONS Acceptance of and adherence to G-CSF GL differed between lung cancer, lymphoma, and breast cancer. Physicians overestimate their adherence to the GL. Physicians adhering to the GL can be characterized.

Cost-effectiveness of first-line induction and maintenance treatment sequences in non-squamous non-small cell lung cancer (NSCLC) in the U.S. Lung Cancer 2015; 89:294-300. [PMID: 26122345 DOI: 10.1016/j.lungcan.2015.05.020] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2014] [Revised: 05/19/2015] [Accepted: 05/23/2015] [Indexed: 11/26/2022]
Abstract
OBJECTIVES Due to the lack of direct head-to-head trials, there are limited data regarding the comparative effectiveness of induction-maintenance sequences. The objective of this study was to develop a cost-effectiveness model to compare induction-maintenance sequences in the US for the treatment of advanced non-squamous NSCLC. MATERIALS AND METHODS Decision analytic modelling was used to synthesize the treatment effect and baseline risk estimates for nine induction and maintenance treatment sequences, reflecting treatments used in the US. The model was structured using an area-under-the-curve approach and sensitivity analyses were conducted. Model validation was conducted by an independent third party. RESULTS All active maintenance therapy-containing regimens, with the exception of gemcitabine+cisplatin (first-line)→erlotinib (maintenance), were more costly than induction-only regimens. Concerning treatments that may be cost effective, the incremental costs per life-year gained were $121,425, $148,994, and $191,270 for gemcitabine+cisplatin→erlotinib versus gemcitabine+cisplatin→best supportive care (BSC), pemetrexed+cisplatin→BSC versus gemcitabine+cisplatin→erlotinib, and for pemetrexed+cisplatin→pemetrexed versus pemetrexed+cisplatin→BSC, respectively. All other regimens were found to be dominated (carboplatin+paclitaxel→BSC; carboplatin+paclitaxel→erlotinib; carboplatin+paclitaxel→pemetrexed; bevacizumab+carboplatin+paclitaxel→bevacizumab) or extendedly dominated (cisplatin+gemcitabine→pemetrexed). Sensitivity analyses demonstrated stability. CONCLUSIONS Depending on the specific cost-effectiveness threshold used by a decision maker, the most cost-effective treatment sequence may include the referent comparator gemcitabine+cisplatin and the studied regimens of gemcitabine+cisplatin→erlotinib, pemetrexed+cisplatin→BSC, or pemetrexed+cisplatin→pemetrexed.
