Economic assessment of NGS testing workflow for NSCLC in a healthcare setting.

Background: The molecular diagnostic and therapeutic pathway of Non-Small Cell Lung Cancer (NSCLC) stands as a successful example of precision medicine. The scarcity of material and the increasing number of biomarkers to be tested have prompted the routine application of next-generation-sequencing (NGS) techniques. Despite its undeniable advantages, NGS involves high costs that may impede its broad adoption in laboratories. This study aims to assess the detailed costs linked to the integration of NGS diagnostics in NSCLC to comprehend their financial impact. Materials and methods: The retrospective analysis encompasses 210 cases of early and advanced stages NSCLC, analyzed with NGS and collected at the IRCCS San Gerardo dei Tintori Foundation (Monza, Italy). Molecular analyses were conducted on FFPE samples, with an hotspot panel capable of detecting DNA and RNA variants in 50 clinically relevant genes. The economic analysis employed a full-cost approach, encompassing direct and indirect costs, overheads, VAT (Value Added Tax). Results: We estimate a comprehensive cost for each sample of €1048.32. This cost represents a crucial investment in terms of NSCLC patients survival, despite constituting only around 1% of the expenses incurred in their molecular diagnostic and therapeutic pathway. Conclusions: The cost comparison between NGS test and the notably higher therapeutic costs highlights that the diagnostic phase is not the limiting economic factor. Developing NGS facilities structured in pathology networks may ensure appropriate technical expertise and efficient workflows.

Epidemiology, Patients' Journey and Healthcare Costs in Early-Stage Non-Small-Cell Lung Carcinoma: A Real-World Evidence Analysis in Italy.

This real-world analysis aims to estimate the epidemiology and economic burden related to early-stage non-small-cell lung carcinoma (eNSCLC) in the clinical practice Italian setting. An observational analysis was performed using administrative databases linked to pathological anatomy data, covering around 2.5 mln health-assisted individuals. From 2015 to mid-2021, eNSCLC patients staged II-IIIA treated with chemotherapy after surgery were included. Patients were stratified into those presenting loco-regional or metastatic recurrence during follow-up and annualized healthcare direct costs covered by the Italian National Health System (INHS) were estimated. In 2019-2020, the prevalence of eNSCLC was 104.3-117.1/million health-assisted subjects, and the annual incidence was 38.6-30.3/million. Data projected to the Italian population estimated 6206 (2019) and 6967 (2020) prevalent and 2297 (2019) and 1803 (2020) incident cases. Overall, 458 eNSCLC patients were included. Of them, 52.4% of patients had a recurrence (5% loco-regional-recurrence, 47.4% metastatic-recurrence). Healthcare total direct costs/patient averaged EUR 23,607, in particular, in the first year after recurrence, costs averaged EUR 22,493 and EUR 29,337 in loco-regional and metastatic-recurrence patients, respectively. This analysis showed that about one-half of eNSCLC patients stage II-IIIA experience a recurrence, and in recurrence patients, total direct costs were almost two-fold those of no-recurrence patients. These data highlighted an unmet clinical need, as the therapeutic optimization of patients at early stages.

Host immune-inflammatory markers to unravel the heterogeneous outcome and assessment of patients with PD-L1 ≥50% metastatic non-small cell lung cancer and poor performance status receiving first-line immunotherapy.

BACKGROUND: Patients with programmed cell death-ligand 1 (PD-L1) ≥50% metastatic non-small cell lung cancer (mNSCLC) and ECOG performance status (PS) of 2 treated with first-line immunotherapy have heterogeneous clinical assessment and outcomes. METHODS: To explore the role of immune-inflammatory surrogates by the validated lung immuno-oncology prognostic score (LIPS) score, including the neutrophil-to-lymphocyte ratio (NLR) and the pretreatment use of steroids, alongside other prognostic variables. A retrospective analysis of 128 patients with PS2 and PD-L1 ≥50% mNSCLC treated between April 2018 and September 2019 with first-line pembrolizumab in a real-world setting was performed. RESULTS: With a median follow-up of 15.3 months, the 1-year overall survival (OS) and median progression-free survival (PFS) were 32.3% (95% CI: 30.9-33.9) and 3.3 months (95% CI: 1.8-4.7), respectively. The NLR, lactate dehydrogenase (LDH) and pretreatment steroids results were the only significant prognostic factors on the univariate analysis and independent prognostic factors by the multivariate analysis on both OS and PFS. The LIPS score, including the NLR and pretreatment steroids, identified 29 (23%) favourable-risk patients, with 0 factors, 1-year OS of 67.6% and median PFS of 8.2 months; 57 (45%) intermediate-risk patients, with 1 factor, 1-year OS 32.1% and median PFS 2.7 months; 42 (33%) poor-risk patients, with both factors, 1-year OS of 10.7% and median PFS of 1.2 months. CONCLUSIONS: The assessment of pre-existing imbalance of the host immune response by combined blood and clinical immune-inflammatory markers may represent a way to unravel the heterogeneous outcome and assessment of patients with mNSCLC and poor PS in the immune-oncology setting.

Treatment Patterns, Clinical Outcomes and Healthcare Costs of Advanced Non-Small Cell Lung Cancer: A Real-World Evaluation in Italy.

We aimed at describing treatment pathways, clinical outcomes and healthcare costs of advanced non-small cell lung cancer (NSCLC) patients in Lombardy Region, Italy. Using healthcare administrative data, 37,562 patients with a new diagnosis of lung cancer between 2012 and 2019 were identified. Among these, patients who started a first-line treatment for advanced NSCLC with either pembrolizumab (n = 660) or tyrosine-kinase inhibitors (TKI) (n = 1245) before 30 June 2020 were included in the study cohort and followed-up until 31 December 2020. Among pembrolizumab users, median time-to-treatment failure (TTF) and median overall survival (OS) were 3.2 months and 13.6 months, respectively. About one third (34.1%) switched to second-line treatment (chemotherapy for all of them). Among TKI users, median TTF and median OS were 9.3 months and 18.4 months, respectively, and 37.1% of patients started second-line treatment (17.8% with TKI and 19.2% with chemotherapy). Average per-patient cumulative healthcare costs during the first year after first-line treatment start were 51,735 € and 30,708 €, respectively, in pembrolizumab and TKI first-line users. These results are coherent with those reported from other real--world studies and may help both clinicians and health decision makers.

Economic burden of patients affected by non-small cell lung cancer (NSCLC): the LIFE study.

PURPOSE: Non-small cell lung cancer (NSCLC) is a condition with significant clinical burden for patients and relevant economic impact. Limited evidence exists on the management costs of NSCLC patients, especially in the late phases of the disease. The main objective of this analysis was to evaluate the economic impact of clinical management of NSCLC patients in the Italian population. METHODS: This evaluation was an economic analysis of the observational and multicentre study LIFE, which described the therapeutic approach in routine clinical practice for NSCLC patients, progressing after first-line treatment. This study evaluated resource consumption in different Italian hospitals, including specialist visits, hospitalizations, accesses to first aid, pharmacological treatment, laboratory tests and palliative care. The National Healthcare Service perspective was adopted. RESULTS: In this study, N = 191 patients enrolled in the LIFE study were included. Patients were aged 64.2 years and were predominantly males (66%). In the different line of treatments, monthly costs of patients ranged between €1471 (first line) and €1788 (third line). The overall healthcare cost over the average period of observation (16.4 months) was €25,859 per patient. Overall, oncology therapy was the cost driver, although the composition of medical costs changed across the different lines of treatment, with costs for concomitant medication and palliative care being predominant in late phase of the disease. CONCLUSIONS: The economic burden of NSCLC is extremely high during the overall period of treatment, and a significant level of care is required in each stage of the disease.

Chemotherapy-induced anemia and oncologist perception on treatment: results of a web-based survey.

AIMS AND BACKGROUND: Anemia prevalence and incidence in chemotherapy-treated patients is high. Erythropoiesis-stimulating agents (ESAs) are frequently employed in the management of chemotherapy-induced anemia. However, other treatments such as red blood transfusion or iron supplementation are normally used. Recent international guidelines raised some concern about ESAs employment with a possible impact in chemotherapy-induced anemia management and changes in clinical practice behavior. METHODS: To evaluate opinions about chemotherapy-induced anemia clinical management preference, the Associazione Italiana Oncologia Medica (AIOM) Lombardy section coordinators sent via email a 12-item questionnaire about their knowledge on CIA and usual therapeutic strategies to manage this adverse event to AIOM Lombardy onco-hematologist members. RESULTS: From January 2011 to March 2011, 81 questionnaires were collected with an approximated share of 30%. The survey was completed mainly by oncologists (91%) aged 35-50 years (50%). Chemotherapy-induced anemia was considered to have clinical impact in changing cancer therapeutic strategy by nearly 60% of the respondents. ESAs were administered largely (80%) with concomitant iron supplementation in 52%; 38% jointly used blood transfusion as part of the therapy. Nearly 20% of those who replied correctly employed transferrin saturation levels as a marker to guide iron supplementation. Physician prescribers strictly followed the guidelines to start and stop ESAs even if 14% were negatively influenced by new ASCO recommendations. ESA biosimilars were considered future substitutes of originators in 45% of the cases. CONCLUSIONS: Chemotherapy-induced anemia was perceived as an adverse event with a mild impact on clinical practice. ESAs were largely employed, however the number of transfusions and lack of employment of markers of iron depletion suggested that adherence to guidelines could be theoretically met but with some discordances regarding the most appropriate strategies in daily clinical practice.

Chemotherapy-Induced Peripheral Neurotoxicity assessment: a critical revision of the currently available tools.

Chemotherapy-Induced Peripheral Neurotoxicity (CIPN) is a frequent, potentially severe and dose-limiting side-effect of cancer treatment. Despite its clinical relevance that limits the use of several antineoplastic agents and even the future development of new anticancer drugs, several crucial aspects of CIPN remain unsolved, one of which is how to assess its occurrence and severity in the most effective and reliable way. CIPN severity is generally assessed using Common Toxicity Criteria (CTC) scales, although it is well known that significant inter-observer disagreement exists using these scales. Moreover, most CTC scores mix impairment, disability and quality of life measures, which could lead to misinterpretation of the results and unpredictable under- or overestimation of the effect. This uncertainty may lead to different interpretations of the results of the same clinical trials by clinicians and also by regulatory agencies. The use of other types of scale based on clinical and instrumental examinations, or the use of self-administered questionnaires for patients, has not yet really improved the accuracy of CIPN assessment, although some of these tools are promising and deserve to be further validated. As a result, there is a general recognition that CIPN has still not been properly assessed and that improvements should be made. In this review, the available data regarding the different tools used to assess CIPN will be revised and their features will be critically examined, with a special focus on their reliability and reproducibility across examiners and, when available, through direct comparison.

Informal caregiving burden in advanced non-small cell lung cancer: the HABIT study.

INTRODUCTION: This study's aim was to assess economic data regarding the home assistance burden for advanced non-small cell lung cancer (NSCLC) patients in Italy. PATIENTS AND METHODS: One hundred four NSCLC patients in second-line chemotherapy (2LC) or in supportive therapy (ST) were enrolled in 18 Italian oncology departments and were observed for 3 months. The main caregiver's workload was assessed monthly by a task scale; other caregivers' activities were also registered. Eastern Cooperative Oncology Group performance status was assessed by physicians, and patients completed the Lung Cancer Symptoms (LCS) subscale. Formal caregiving time was valued according to market prices; informal caregiving hours were valued using the wage rate for an equivalent service. Covariance analysis was performed to check for influential factors in assistance costs. RESULTS: The mean age of the total sample was 65.5 years, and prevalence of males was over 80%. In over 70% of cases, the principal caregiver was patient's spouse, living with the patient and not working. Principal caregiver support was the main cost item: 2.368 euros in 2LC and 2.805 euros in ST, representing 74% of total trimonthly assistance costs. Regression analysis showed a positive correlation between the severity of symptoms and the costs of assistance. The caregiving burden was higher in patients with bone and/or cerebral metastases; other metastasis sites seemed to have no impact on assistance costs. CONCLUSION: Considering quality of life as the ultimate health outcome, clinicians are challenged to contribute to a research and policy agenda that holds burden of care in due consideration.
