Purpose: To analyze the correlation of primary tumor (PT) pathological characteristics (size, stage, type and grade) and the extent of initial surgical treatment of non small cell lung cancer (NSCLC) with the incidence and time to local recurrence (LR) and disease-free survival (DFS), as well as to determine in what way these parameters and LR localizations affect the possibility for surgical retreatment. Methods: The research was conducted on 114 patients with NSCLC and LR that had initial surgery in two reference institutes in Serbia from January 2002 to December 2010. PT size and disease stage were defined according to the revised 2004 WHO classification. PTs were grouped by size into 3 categories. Due to great diversity, surgical procedures were sorted into 6 operation types. Standard statistical methods and tests were used for data analysis. Results: Statistical analyses showed significant difference in DFS and LR reoperability that were related to PT size, disease stage and the extent of initial surgery. LR localization on the chest wall was favorable for secondary surgery due to LR. Conclusions: Squamous cell lung carcinoma relapses locally more frequently than other lung tumor types, and the commonest LR site is the chest wall. This localization provides high possibility for surgical retreatment. Adequate staging, proper indications for surgical treatment and quality surgery provide longer DFS in patients with NSCLC. All these suggest that the surgeon may be considered as the most significant factor of prognosis.

Objective: The aim of this study was to investigate the level of burnout and identify who is at highest risk among healthcare professionals (HCPs) working at the largest referent national institution. Methods: A cross-sectional survey was conducted at the Institute of Oncology and Radiology of Serbia from May 2019 to July 2019, evaluating the level of burnout, depression, fatigue, socio-demographic, behavioral and professional characteristics, and quality of life among healthcare professionals. Of the 576 distributed questionnaires among physicians, nurses/technicians and healthcare coworkers, 432 participants returned their questionnaires (75%). All instruments used in our study had been validated and cross-culturally adapted to Serbian language. Results: The overall prevalence of burnout was 42.4%, with the greatest proportion of burned out in emotional exhaustion domain (66.9%). The multivariable-adjusted model analysis showed that nurses/technicians had a 1.41 times greater chance of experiencing burnout, compared to physicians (OR = 1.41, 95% CI 1.16–7.10), and that with each year of work experience, the chance of burnout increased by about 2% (OR = 1.02, 95% CI 1.00–1.92). Furthermore, it was shown that, with each point in the PHQ-9 score for depression, probability of burnout increased by 14% (OR = 1.14, 95% CI 1.07–1.94). Finally, after controlling all these potential confounders, the Mental Composite Score of SF-36 score showed an independent prognostic value in exploring the burnout presence among HCPs (OR = 1.17, 95% CI 1.03–2.47). Conclusion: Our research showed a significant level of burnout among healthcare professionals working in oncology, especially among nurses/technicians. The development of effective interventions at both individual and organizational level toward specific risk groups is needed. © 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH, DE part of Springer Nature.
