Sequential afatinib and osimertinib in patients with EGFR mutation-positive non-small-cell lung cancer : updated analysis of the observational GioTag study
Maximilian J Hochmair, Alessandro Morabito, Desiree Hao, Cheng-Ta Yang, Ross A Soo, James C-H Yang, Rasim Gucalp, Balazs Halmos, Lara Wang, Angela Märten, Tanja Čufer, 2019

Povzetek: Aims: Overall survival (OS) and updated time to treatment failure (TTF) analysis of patients with EGFR mutation-positive (Del19, L858R) non-small-cell lung cancer who received sequential afatinib/osimertinib in the real-world GioTag study. Patients & methods: Patients had T790M-positive disease following first-line afatinib and received osimertinib treatment (n = 203). Primary outcome was TTF. The OS analysis was exploratory. Results: Median OS was 41.3 months (90% CI: 36.8-46.3) overall and 45.7 months (90% CI: 45.3-51.5) in patients with Del19-positive tumors (n = 149); 2-year survival was 80 and 82%, respectively. Updated median TTF with afatinib and osimertinib was 28.1 months (90% CI: 26.8-30.3). Conclusion: Sequential afatinib/osimertinib was associated with encouraging OS/TTF in patients with EGFR T790M-positive non-small-cell lung cancer, especially in patients with Del19-positive tumors.

Non-small cell lung cancer in countries of Central and Southeastern Europe : diagnostic procedures and treatment reimbursement surveyed by the Central European Cooperative Oncology Group
Ales Ryška, Rares Buiga, Albena Fakirova, Izidor Kern, Włodzimierz Olszewski, Lukas Plank, Sven Seiwerth, Erika Toth, Eri Zivka, Christiane Thallinger, Christoph Zielinski, Luka Brčić, 2018

Povzetek: This article analyzes the availability of different diagnostic procedures of non-small cell lung cancer (NSCLC) and the reimbursement landscape of drugs for NSCLC in countries of central and southeastern Europe (CEE). A survey was conducted by the Central European Cooperative Oncology Group. Results of the survey show that both availability and reimbursement of diagnoses of molecular alterations in NSCLC, the detection of which is essential for therapeutic decisions, varies widely between countries of CEE. Not only is "reflex" testing often substituted by analyses performed only "on demand," but reimbursement of such assessments varies widely between unavailability and payments by the health care system or even pharmaceutical companies. It was concluded that a structured access to testing and reimbursement should be the aim in order to provide patients with appropriate therapeutic options. Implications for Practice. This article provides an overview of the limitations in lung cancer treatment in countries of central and southeastern Europe, as well as the reimbursement status of various lung cancer treatment regimens in these countries, which directly impacts treatment options.

Maximilian J Hochmair, Alessandro Morabito, Desiree Hao, Cheng-Ta Yang, Ross A Soo, James C-H Yang, Rasim Gucalp, Balazs Halmos, Angela Märten, Tanja Čufer, 2020

Povzetek: Aim: Final overall survival (OS) and time on treatment analysis of patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC) who received sequential afatinib and osimertinib. Patients & methods: Patients (n = 203) had T790M-positive disease following first-line afatinib and started osimertinib treatment >/=10 months before data entry. Primary outcome was time on treatment; OS analysis was exploratory. Results: Median time on treatment with afatinib and osimertinib was 27.7 months (90% CI: 26.7-29.9). Median OS was 37.6 months (90% CI: 35.5-41.3); median OS was 41.6 and 44.8 months in Del19-positive patients and Asian patients, respectively. Conclusion: In real-world clinical practice, sequential afatinib and osimertinib was associated with encouraging outcomes in patients with EGFR mutation-positive NSCLC, especially in Del19-positive patients and Asian patients.

Pathologic grading of malignant pleural mesothelioma : an evidence-based proposal
Giuseppe Pelosi, Mauro Papotti, Luisella Righi, Giulio Rossi, Stefano Ferrero, Silvano Bosari, Izidor Kern, 2018

Povzetek: Introduction: A pathologic grading system (PGS) for malignant pleural mesothelioma (MPM) is warranted to better identify different risk categories of patients, plan therapeutic options, and activate clinical trials. Methods: A series of 940 patients with MPM (328 in a training set and 612 in a validation set) that was diagnosed between October 1980 and June 2015 at the participant institutions was retrospectively assembled. A PGS was constructed by attributing to each histologic parameter, independent at multivariate analysis with excellent reproducibility (κ > 0.75), different scores based on the increase in corresponding hazard ratios. The relevant PGS score thus ranged from 0 to 8 points for individual patients with MPM. Conclusions: The PGS was constructed by taking into consideration the histological subtyping of MPM (epithelioid/biphasic = 0 points; sarcomatoid = 2 points), necrosis (absent = 0 points versus present = 1 point), mitotic count per 1 mm2 (cutoffs as follows: 1-2 = 0 points, 3-5 = 1 point, 6-9 = 2 points, or ≥10 = 4 points), and Ki-67 labeling index based on 2000 cells (<30% = 0 points versus ≥30 = 1 point), all of which are independent factors in both patient sets after adjustment for stage and age at diagnosis. No heterogeneity was seen across the validation centers (p = 0.19). Epithelioid/biphasic MPM patterning and biopsy versus resection did not affect survival, whereas the PGS outperformed mitotic count and Ki-67 LI in both the training (area under the curve receiver operating characteristic = 0.76) and validation sets (area under the curve receiver operating characteristic = 0.73) (p < 0.01). Patient survival progressively deteriorated from a score of 0 (median times of 26.3 and 26.9 months) to a score 1 to 3 (median times of 12.8 and 14.4 months) and a score of 4 to 8 (median times of 3.7 and 7.7 months) in both sets of patients, with the hazard ratio for a 1-point increase in score being 1.46 (95% confidence interval: 1.36-1.56) in the training set and 1.28 (95% confidence interval: 1.22-1.34) in the validation set (after adjustment for age and [when available] tumor stage). The PGS was effective even in subgroup analysis (epithelioid, biphasic, and sarcomatoid tumors). Discussion: A simple and reproducible multiparametric PGS effectively predicted survival in patients with MPM.

Trans-esophageal endobronchial ultrasound-guided needle aspiration (EUS-B-NA) : a road map for the chest physician
António Bugalho, Maria De Santis, A. Szlubowski, Aleš Rozman, R. Eberhardt, 2018

Povzetek: The endobronchial ultrasound (EBUS) scope has been increasingly used in the gastrointestinal tract (EUS-B). Scientific data proves its efficacy and safety to provide a complete lung cancer staging, when combined with EBUS-TBNA, and in the diagnosis of para-esophageal lesions. There are multiple barriers to start performing EUS-B but probably the most important ones are related to knowledge and training, so new operators should follow a structured training curriculum. This review aims to reflect the best current knowledge regarding EUS-B and provide a road map to assist those who are incorporating the technique into their clinical practice.

NSCLC molecular testing in Central and Eastern European countries
Ales Ryška, Peter Berzinec, Luka Brčić, Tanja Čufer, Rafal Dziadziuszko, Maya Gottfried, Ilona Kovalszky, Włodzimierz Olszewski, Buge Oz, Lukas Plank, József Tímár, 2018

Povzetek: Background: The introduction of targeted treatments for subsets of non-small cell lung cancer (NSCLC) has highlighted the importance of accurate molecular diagnosis to determine if an actionable genetic alteration is present. Few data are available for Central and Eastern Europe (CEE) on mutation rates, testing rates, and compliance with testing guidelines. Methods: A questionnaire about molecular testing and NSCLC management was distributed to relevant specialists in nine CEE countries, and pathologists were asked to provide the results of EGFR and ALK testing over a 1-year period. Results: A very high proportion of lung cancer cases are confirmed histologically/cytologically (75-100%), and molecular testing of NSCLC samples has been established in all evaluated CEE countries in 2014. Most countries follow national or international guidelines on which patients to test for EGFR mutations and ALK rearrangements. In most centers at that time, testing was undertaken on request of the clinician rather than on the preferred reflex basis. Immunohistochemistry, followed by fluorescent in situ hybridization confirmation of positive cases, has been widely adopted for ALK testing in the region. Limited reimbursement is a significant barrier to molecular testing in the region and a disincentive to reflex testing. Multidisciplinary tumor boards are established in most of the countries and centers, with 75-100% of cases being discussed at a multidisciplinary tumor board at specialized centers. Conclusions: Molecular testing is established throughout the CEE region, but improved and unbiased reimbursement remains a major challenge for the future. Increasing the number of patients reviewed by multidisciplinary boards outside of major centers and access to targeted therapy based on the result of molecular testing are other major challenges.

Morphologic and molecular classification of lung neuroendocrine neoplasms
Jasna Metovic, Marco Barella, Fabrizio Bianchi, Paul Hofman, Veronique Hofman, Myriam Remmelink, Izidor Kern, Lina Carvalho, Linda Pattini, Angelica Sonzogni, 2021

Povzetek: Neuroendocrine neoplasms (NENs) of the lung encompass neuroendocrine tumors (NETs) composed of typical (TC) and atypical (AC) carcinoids and full-fledged carcinomas (NECs) inclusive of large cell neuroendocrine carcinoma (LCNEC) and small cell carcinoma (SCLC). NETs and NECs are thought to represent distinct and separate lesions with neither molecular overlap nor common developmental continuum. Two perspectives were addressed regarding the morphologic and molecular classification of lung NENs: (i) a supervised approach by browsing the traditional classification, the relevant gene alterations, and their clinical implications; and (ii) an unsupervised approach, by reappraising neoplasms according to risk factors and natural history of disease to construct an interpretation model relied on biological data. We herein emphasize lights and shadows of the current classification of lung NENs and provide an alternative outlook on these tumors focused on what we currently know about the biological determinants and the natural history of disease.
