Objectives: To determine the prescribing prevalence of epidermal growth factor receptor (EGFR)- and anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) patients in Greece and examine patterns of first-line tyrosine kinase inhibitor (TKI) utilization and associated treatment costs using nationwide real-world data. Methods: A retrospective analysis of the national e-prescription database was performed, identifying patients initiating first-line treatment (FLT) for EGFR- or ALK-positive NSCLC between 1 January 2020 and 31 December 2022. Demographic characteristics, prescribing prevalence data, drug utilization patterns, total annual drug expenditures, and per patient treatment costs were assessed. All statistical analyses were performed using the statistical software SPSS-v.29. Results: Overall, 1188 EGFR-positive (mean age of 70.93 ± 11.6) and 246 (mean age of 64.26 ± 12.6) ALK-positive NSCLC patients initiated FLT during the three-year study period. EGFR mutations were slightly more common in females (53%), peaking in the 70–79 age group (35%). ALK mutations were also more common among females (52%), particularly within the 60–79 age group. In EGFR-positive patients, osimertinib usage markedly increased from 41% in 2020 to 63% in 2022, primarily displacing afatinib (from 32% to 22%) and erlotinib (from 24% to 14%), with gefitinib prescriptions falling below 2%. Among ALK-positive patients, crizotinib utilization declined significantly from 60% to 16%, whereas alectinib increased to 59% by 2022. Annual EGFR-related total drug expenditures remained stable (€11.5 million in 2020 vs. €11.9 million in 2022), driven primarily by increasing osimertinib usage. Similarly, ALK-related annual drug expenditures showed stability, with costs predominantly attributed to rising alectinib utilization. Conclusions: This nationwide analysis highlights the rapid adoption of second- and third-generation TKIs for EGFR- and ALK-positive NSCLC in Greece, reflecting evolving clinical practice patterns. Although the target patient populations are relatively small, the associated economic burden is considerable. To ensure long-term sustainability of the Greek healthcare system, policymakers should critically assess the cost-effectiveness of these innovative therapies and align resource allocation with value-based care principles.

Objective: This systematic literature review aimed to summarize the economic burden of lung cancer in Greece, identify current data gaps, and support the design of future real-world studies. Methods: A systematic search of studies published in English on the cost of lung cancer was performed in MEDLINE-(PubMed), Scopus, and ScienceDirect. The databases were searched until September 2024, and records were screened based on our eligibility criteria. After conducting the initial literature search, the abstracts and full texts of the identified studies were reviewed and evaluated for inclusion based on predefined criteria. Data from the selected studies were then extracted into a standardized form and subsequently synthesized. Results: Seven studies were included in this review. The reported burden was sourced from hospital data and categorized as direct and indirect costs. Most studies (n = 6) reported direct costs, with one study reporting both direct and indirect costs. The total direct medical cost per patient increased from approximately EUR 16,000 in 2015 to EUR 58,974 in 2023, with drug acquisition costs being the key driver of the total direct cost. Additionally, the cost of end-of-life care during the final six months of a patient’s life was estimated to range from EUR 6786 to EUR 7665 per patient, with pharmaceutical costs comprising the largest proportion of the total cost. One study also reported that indirect costs were considerably higher for patients than for family caregivers. Conclusion: The economic burden of lung cancer has increased substantially over the past decade in Greece. The present systematic review emphasizes the critical need for comprehensive real-world studies on the economic burden of lung cancer in Greece. Addressing the current gaps holistically will yield invaluable insights for policymakers and stakeholders.

The economic crisis in Greece, which began in 2010 and lasted for 10 years, highlighted the serious problems and challenges of the Greek Social Health Insurance system. The reforms that mainly took place during the crisis provided a temporary solution. They focused on establishing a new National Organization for Healthcare Services (named EOPYY) and merging all the old insurance funds. This paper aims to examine whether this social health insurance fund has been sustainable in the long run. An actuarial model was created to project future expenses and revenues. Demographic and economic trends were considered, while it was assumed that medical technology remains unaltered. The assessment of the system solvency was based on the ratio (Revenue/Liabilities) calculated for each year, from 2020 to 2050. The results led to deficits, the amount and the time point in which they appear depends on how optimistic or pessimistic demographic and economic assumptions were. A new financial flow model was proposed to address the deficits. The results show that under the new model, the system remains solvent until 2050. The state subsidy amount on the employees’ health insurance premium was estimated as a percentage of the employees’ wage.

Background: Ulcerative colitis (UC) requires life-long disease management. This study aimed to investigate the disease burden and unmet medical needs in UC patients in Greece. Methods: Between October 2023 and January 2024, adult UC patients who were members of the Hellenic Society of Crohn’s Disease and Ulcerative Colitis Patients (HELLESCC) completed a structured self-reported questionnaire. The survey questionnaire included sociodemographic characteristics, smoking habits, history of comorbidities, disease activity, disease characteristics, medications, and patient-reported outcomes (PROs; Short Inflammatory Bowel Disease Questionnaire [SIBDQ], Work Productivity and Activity Impairment [WPAI], Patient Health Questionnaire-9 [PHQ-9], treatment satisfaction, and treatment adherence). Univariate and multivariate logistic regression analyses were used to identify associated factors. Results: Datasets were obtained from 181 UC patients, of whom 48% were on advanced therapies (biological/small-molecule agents) and 54% had active disease. Around 74% reported impaired quality of life (QoL) (SIBDQ < 60), 25% work productivity loss, and 29% daily activity impairment. About 40% reported moderate to severe depressive symptoms (PHQ-9 ≥ 10). Reduced adherence and treatment dissatisfaction were reported by approximately one-third of patients. Female gender and disease activity were associated with moderately to severely impaired QoL, work productivity, and mental health. Interestingly, three out of four patients receiving advanced therapy reported moderately to severely impaired QoL and had increased odds of experiencing moderate to severe depression. Conclusions: The disease burden remains very high in UC, characterized by poor QoL and increased work impairment, depression, and disease activity among Greek patients. Marked treatment dissatisfaction and non-adherence were observed in approximately one-third of patients.

Several European administrations have applied various mechanisms promoting cost containment to stabilise their budgets for pharmaceutical expenditure. Since 2016, Greece has adopted the clawback as a policy to contain the NHS hospitals' pharmaceutical expenditure, which increased significantly in the 2016–2020 period. The present study reviews the impact of this policy on the operation of NHS hospitals, the uninterrupted supply and rational use of their medicines, along with the sustainability of their finances. The trend of pharmaceutical expenditure for the period 2016–2020 is combined with further analysis of detailed drug consumption data of 15 sampled NHS hospitals. The data is classified by Anatomical Therapeutic Category (ATC) and the percentage of clawback distributed to each ATC and pharmaceutical company is calculated. It was found that a large proportion of the clawback is allocated to a few therapeutic categories (ATCs) and consequently, few pharmaceutical companies are particularly burdened. The increased burden on pharmaceutical companies, due to the continuous increase in the excessive pharmaceutical expenditure of the NHS hospitals and their limited budget, endangers the uninterrupted supply of medicines to hospitals and the viability of pharmaceutical companies. This issue was discussed in a scientific consensus group*, in which participants proposed ways to keep the level of pharmaceutical expenditure in line with patients' needs, the country's economic potential, and the sustainability of pharmaceutical companies.

Background: While the clinical application of SII-ONCO-Bacillus Calmette–Guerin (BCG) for non-muscle-invasive bladder cancer (NMIBC) is well established in Greece, there is a lack of real-world data on its effectiveness and safety. This retrospective, observational, multicenter, chart-review study aims to provide real-life data on the effectiveness and safety of SII-ONCO-BCG in patients with intermediate- and high-risk NMIBC. Methods: From January 2016 to December 2023, medical records from six hospital centers were reviewed for adult patients with histologically confirmed stage Ta or T1 NMIBC (with or without carcinoma in situ [CIS]) who received at least one maintenance course of SII-ONCO-BCG after induction. Tumor recurrence and progression were monitored at scheduled time intervals. Primary outcomes included recurrence-free survival (RFS) and progression-free survival (PFS), while adverse events (AEs) constituted secondary outcomes. Results: A total of 162 patients receiving SII-ONCO-BCG were enrolled. Among all patients, 145 (89.5%) patients were men, 88 (54.3%) aged 70 years or older, 103 (63.6%) had T1, 43 (26.5%) Ta, and 21 (12.9%) concurrent CIS. The median follow-up duration was 28.9 months (range, 5–36) and the mean BCG intravesical instillation courses were 13.7 (range, 9–27). After 3-, 2-, and 1-year follow-up, RFS rates of 85.2% (95% CI, 79.7–90.7%), 85.8% (80.4–91.2%), and 87.0% (81.8–92.3%) were observed, respectively. The corresponding 3-, 2-, and 1-year PFS rates were 96.9% (94.2–99.6%), 96.9% (94.2–99.6%), and 97.5% (95.1–99.9%), respectively. During the whole follow-up period, 24 (14.8%) patients experienced at least one AE. Conclusions: This real-world study demonstrates that SII-ONCO-BCG is an effective and safe treatment for patients with intermediate- and high-risk NMIBC.
