Summary
Background: The purpose of this study was to investigate how oncologists in Croatia use NGS tests to evaluate cancer patients. Methods: The study was conducted in the period from September 01 to October 02, 2022 through an electronic anonymous Google form online survey sent to e-mails of oncologists from the database of the Croatian Society for Medical Oncology (N=120, cooperation rate 62%). The goal of the research was to determine how often we use NGS tests in oncology practice in Croatia, in which indications and for what purpose, do we have problems with the interpretation of NGS results and do the NGS results affect our decision to treat patients. We were also interested in the satisfaction with the conditions of molecular testing in Croatia and what are currently the biggest challenges of molecular testing in Croatia from the perspective of oncologists. Results: The majority of oncologists surveyed reported using NGS tests in their clinical practice (25% often, 60% sometimes). Testing is mainly indicated for patients with rare tumors and advanced refractory malignant disease (57%) and tumors of unknown primary origin (50%). The most common reasons for using NGS are: to provide insurer-approved targeted therapy (75%), treat through “compassionate” or “off-label” drug use (69%), or determine eligibility for clinical trials (33%). The majority of respondents have problems with the interpretation of NGS results (71% sometimes, 8% often), and the NGS results influence the treatment decision in most respondents (29% often, 64% sometimes). The majority of respondents are not satisfied with the current conditions of molecular testing in Croatia (60% partially satisfied, 32% dissatisfied). The biggest challenges of molecular testing are: the impossibility of treatment according to the test results (81%), the time required to obtain the results (52%), additional financial expenses (38%), and interpretation of test results (37%). Conclusion: The majority of oncologists in Croatia use NGS tests in their clinical practice and the results of NGS significantly influence treatment decisions. It is necessary to improve the conditions of molecular testing in Croatia and provide support when
interpreting NGS results.
