Omission of staging PET/CT linked to reduced survival in stage III non-small cell lung cancer: insights from the LUCAS project real-world data.

Background: Stage III non-small cell lung cancer (NSCLC) is a highly heterogeneous stage due to its subgroups (IIIA-IIIC) comprising both resectable and unresectable tumors. Accurate determination of the extent of the disease is essential for excluding stage IV and choosing the optimal treatment regimen. Whole body positron emission tomography and computed tomography scan (PET/CT) is recommended as an initial staging imaging in locally advanced NSCLC. Despite international guidelines for NSCLC diagnosis and treatment, they are not always adhered to due to various reasons. Even in such a groundbreaking study, the phase 3 trial PACIFIC investigating the efficacy of durvalumab as consolidation therapy in patients with stage III NSCLC PET/CT was not mandatory. With the premise that whole body PET/CT of the trunk is essential for diagnosing stage III NSCLC, we performed a retrospective study evaluating the relationship of the use of PET/CT versus conventional staging with CT of the chest and abdomen, in terms of survival. Methods: This retrospective study of stage III NSCLC patients used the Czech lung cancer registry LUCAS, which was established in June 2018. As of the data export (up to February 9, 2022), a total of 703 patients were eligible for the analysis. Overall survival (OS) was compared using Kaplan-Meier analysis and a Cox regression model. Continuous variables were tested using the Mann-Whitney test, and categorical variables using the Pearson's Chi-square or Fisher's exact test. Results: A total of 703 patients were included in the cohort with an average age of 69 years. PET/CT was performed on 354 patients, and conventional staging using chest and abdominal CT on 349 patients. The median OS among patients with PET/CT was 20.9 months [95% confidence interval (CI): 18.1-23.7], and it was statistically significantly higher (P<0.001) than among patients without PET/CT, where the median OS was 9.0 months (95% CI: 7.3-10.6). The observed effect of PET/CT was also statistically significant when comparing individual stages (IIIA, IIIB, IIIC). The multivariate Cox model confirmed the use of PET/CT as an independent prognostic factor. The most common reason for omission of PET/CT was the local or time unavailability of the examination. Conclusions: Omission of PET/CT can mean a significant decrement in survival for the patients in stage III NSCLC, likely due to poor staging and suboptimal treatment. Routine use of PET/CT is strictly recommended for the optimal management of stage III NSCLC patients even outside the high-income countries.

Neurosurgical treatment and outcome patterns in patients with meningioma in South Moravian region-a population-based study.

INTRODUCTION: Meningiomas are usually slow-growing tumours, constituting about one third of all primary intracranial tumours. They occur more frequently in women. Clinical manifestation of meningiomas depends on their location, tumour size and growth rate. In most cases, surgical treatment is the procedure of choice. The success of this treatment is, however, associated with the radicality of the resection. Radiotherapy represents an additional or alternative treatment modality. Gamma knife surgery is another notable treatment method, especially in small and/or slow-growing tumours in eloquent areas or in elderly patients. MATERIAL AND METHODS: Authors describe their experience with the diagnosis, treatment and outcome of the patients with meningioma (n = 857). Furthermore, they also assess the postoperative morbidity/mortality and recurrence rate. RESULTS AND CONCLUSIONS: In view of the benign histology of meningiomas, the success of the treatment largely depends (besides the tumour grading) on the radicality of the resection. The emphasis is also put on appropriate follow-up of the patients. In certain patients, the watch and wait strategy should be also considered as a suitable treatment method.

Lung Cancer in Non-smokers in Czech Republic: Data from LUCAS Lung Cancer Clinical Registry.

BACKGROUND/AIM: LUCAS is a clinical lung cancer registry (ClinicalTrials.gov identifier is NCT04228237), prospectively collecting data from newly diagnosed lung cancer patients in seven pneumooncology centers in the Czech Republic, since June 1, 2018. The aim of the study was to assess the stage of the disease at the time of diagnosis, percentage of morphological types, survival, percentage of driving mutations, eligibility for radical surgery, and percentage of patients who undergo radical surgery, in the non-smoking population in comparison with smokers and former smokers. PATIENTS AND METHODS: The total number of patients in the registry at the time of the analysis was 2,743. Only 2,439 patients with complete records (smoking status, stage, and type of tumor) were included in this study. RESULTS: The analysis indicated that non-smokers are diagnosed at a later stage of the disease but they have a better survival rate than smokers. Fewer smokers with stage III disease who are eligible for radical surgery will undergo surgery compared to non-smokers with the same clinical stage. Driving mutations are more common in non-smokers, even after adjustment for the more frequent occurrence of adenocarcinoma in the group of non-smokers. CONCLUSION: The data from LUCAS registry are consistent with already known facts, suggesting that the LUCAS registry is a useful clinical tool.

SETAP: epidemiology and prevention of stroke and transient ischaemic attack in Czech patients with atrial fibrillation.

AIMS: The aim of this study is to analyse the prevalence, epidemiology, and anticoagulation prevention of stroke or transient ischaemic attack (TIA) in Czech patients with atrial fibrillation (AF). METHODS AND RESULTS: Retrospective observational analysis of diagnoses, procedures, and treatment reported to the Czech National Registry of Reimbursed Healthcare Services between 2015 and 2018. Prevalence of AF in 2018 was 4.3% of Czech population and the prevalence of stroke/TIA in AF patients was 22.3% with annual incidence of 181.62 cases per 100 000 inhabitants. In 2018, CHA2DS2-ASc score ≥4 was present in 98% AF patients in secondary and 59% in primary prevention, respectively, while the anticoagulation treatment was used by 71-81% of them. Between 2015 and 2018, the percentage of AF patients treated with warfarin monotherapy in primary prevention decreased from 35% to 31%, with acetylsalicylic acid (ASA) monotherapy from 18% to 16% and non-vitamin K antagonist oral anticoagulants (NOACs) monotherapy increased from 7% to 11%. In secondary prevention, the percentage of warfarin monotherapy treatment decreased from 35% to 32%, with ASA monotherapy from 20% to 18% and with NOACs monotherapy increased from 9% to 15%. CONCLUSION: This study followed all Czech patients with AF. The unadjusted prevalence and incidence of AF was higher compared with other countries and 2019 European Society of Cardiology Statistics. The study identified several gaps in standard of reimbursed care. 20-30% of AF patients with other risk factors were without any prevention medication and the share of ASA monotherapy in treated patients was 16-18%.

The value of innovation in decision-making in health care in Central Eastern Europe - The Sixth International Conference, 2 June 2017, Belgrade, Serbia.

The Pharmacoeconomics Section of the Pharmaceutical Association of Serbia organised a one day international conference on the value of innovation in decision-making in health care in Central and Eastern Europe. The focus of the conference was on reimbursement decisions for medicines using health technology assessment and the use of managed entry agreements (MEAs). The objectives of this conference were firstly to discuss the challenges and opportunities with the use of MEAs in Central and Eastern European countries; secondly the role of patient registries especially with outcome based schemes, and finally new approaches to improve accessibility to new medicines including better managing their entry.

De novo cost-utility analysis of oral paliperidone in the treatment of schizoaffective disorder.

OBJECTIVES: The aim of this analysis is to compare costs and effectiveness of paliperidone ER vs. placebo in the treatment of schizoaffective disorder (SAD) in the Czech Republic based on pooled clinical trial data. METHODS: A de novo micro-simulation model was developed to assess the cost-utility analysis of paliperidone vs. placebo as there is lack of clinical data comparing paliperidone to other interventions. There are no studies primarily evaluating the efficacy of treatment of SAD with other antipsychotics. The model estimated effectiveness and costs of patients with SAD every week during 24-week time horizon. The effectiveness was defined as improvement of a patient's PANSS score where utilities were assigned to each modelled PANSS score. Based on the patient level data a linear mixed-effects model was used to estimate the regression equations of percentage decrease of PANSS score from the baseline. Utilities were computed using a regression function of patients' age, sex and PANSS score, which was adapted from a clinical study of patients with schizophrenia as there are no QoL data on SAD patients. Among relevant costs, reflecting the payer's perspective, costs of pharmacotherapy, concomitant medications and outpatient care were considered. RESULTS: The average ICER of paliperidone compared to placebo reached 28,935 EUR/QALY. The probability of paliperidone being cost-effective compared to placebo was 99.5%. CONCLUSIONS: Treatment of SAD with paliperidone results in acceptable ICER and high probability of being cost-effective compared to placebo. Thus, it can be considered as a cost-effective treatment of patients with SAD in the Czech Republic.
