A population-based study describing characteristics, survival and the effect of TKI treatment on patients with EGFR mutated stage IV NSCLC in the Netherlands

INTRODUCTION: Since 2011, treatment guidelines advise targeted therapy (tyrosine kinase inhibitor, TKI) for patients with activating epidermal growth factor receptor (EGFR) mutations (EGFR+) in non-small cell lung cancer (NSCLC). We describe characteristics, first line treatment and survival of patients diagnosed with EGFR+ NSCLC in a European population, focussing on age, gender and trends over time and compare to the whole group and EGFR-. METHODS: All patients with non-squamous NSCLC stage IV, diagnosed 2011-2018, were identified from the population-based Netherlands Cancer Registry (N = 31,291). RESULTS: Among all, 7.0% were registered to be EGFR+, with highest prevalence in females 65 years to 23.6 months in the EGFR+ group <50 years treated with TKI. Over time, OS for the whole group increased by 0.6 months, of which 33% due to TKI treatment in EGFR+. The increase was strongest in females <50 years, where median OS almost doubled to 12.4 months. In the EGFR+, multivariable hazard of death was most strongly associated with the use of TKI (HR 0.45(0.41-0.49)). Of the patients with EGFR+ this space need or not, 71% received TKI treatment. Being young reduced the hazard of death (HR 0.71(95%CI:0.59-0.85)) irrespective of treatment, while male gender increased the hazard of death (HR 1.22(95%CI:1.11-1.33)). CONCLUSION: At population level, TKI treatment in patients with non-squamous NSCLC stage IV EGFR+ has very strong beneficial effects on outcome. Of the improvement in OS that was made over the years for the whole group, about one third seems to be attributed to TKI treatment in EGFR+ patients

EUS-FNA of enlarged necrotic lymph nodes may cause infectious mediastinitis

Abstract: Transesophageal endoscopic ultrasound with fine-needle aspiration (EUS-FNA) is a minimally invasive technique to investigate the mediastinum. Although EUS-FNA can be considered in general as a safe technique, complications do occur. We here report an infectious complication of EUS-FNA that occurred after puncture of a large malignant necrotic mediastinal lymph node

The relation between psychological profiles and quality of life in patients with lung cancer

Objective Previous studies in patients with lung cancer examined the association between psychological factors with quality of life (QoL), as well as the association between psychological factors with sociodemographic and medical characteristics. However, knowledge about the impact of combinations of psychological characteristics on QoL is still lacking. Therefore, the current study aimed to identify psychological profiles, covering multiple psychological factors. Additionally, the association between these profiles with QoL and with sociodemographic and medical characteristics was explored. Methods Patients with lung cancer (n = 130, mean age = 68.3 ± 8.6 years; 49% men) completed questionnaires focusing on sociodemographic information, anxiety and depressive symptoms (HADS), coping (COPE-easy), perceived social support (PSSS), and QoL (WHOQOL-BREF). Medical information was extracted from patients’ medical records. A step-3 latent profile analysis was performed to identify the psychological profiles. Multinomial logit models were used to explore the medical and sociodemographic correlates of the profiles and the relation with QoL. Results Four psychological profiles were identified as follows: (1) anxious, extensive coping repertoire (33%); (2) depressive, avoidant coping (23%); (3) low emotional symptoms, active/social coping (16%); and (4) low emotional symptoms, limited coping repertoire (29%). QoL in profile 1 (QoL = 6.59) was significantly different from QoL in profile 3 (QoL = 8.11, p = .001) and profile 4 (QoL = 7.40, p = .01). QoL in profile 2 (QoL = 6.43) was significantly different from QoL in profile 3 (QoL = 8.11, p = .003) and profile 4 (QoL = 7.40, p = .02). Regarding QoL, no other significant differences were found. Sociodemographic and medical characteristics were not distinctive for the profiles (all p values > .05). Conclusion Determining psychological profiles of patients with lung cancer in an early stage provides information that may be helpful in aligning care with patients’ unique needs, as it will help in more adequately selecting those patients who are in need of psychological screening and/or psychological treatment as compared with determining scores on single psychological factors

Prospective cohort study of patients with advanced cancer and their relatives on the experienced quality of care and life (eQuiPe study): A study protocol

Background: Palliative care is becoming increasingly important because the number of patients with an incurable disease is growing and their survival is improving. Previous research tells us that early palliative care has the potential to improve quality of life (QoL) in patients with advanced cancer and their relatives. According to limited research on palliative care in the Netherlands, patients with advanced cancer and their relatives find current palliative care suboptimal. The aim of the eQuiPe study is to understand the experienced quality of care (QoC) and QoL of patients with advanced cancer and their relatives to further improve palliative care. Methods: A prospective longitudinal observational cohort study is conducted among patients with advanced cancer and their relatives. Patients and relatives receive a questionnaire every 3 months regarding experienced QoC and QoL during the palliative trajectory. Bereaved relatives receive a final questionnaire 3 to 6 months after the patients' death. Data from questionnaires are linked with detailed clinical data from the Netherlands Cancer Registry (NCR). By means of descriptive statistics we will examine the experienced QoC and QoL in our study population. Differences between subgroups and changes over time will be assessed while adjusting for confounding factors. Discussion: This study will be the first to prospectively and longitudinally explore experienced QoC and QoL in patients with advanced cancer and their relatives simultaneously. This study will provide us with population-based information in patients with advanced cancer and their relatives including changes over time. Results from the study will inform us on how to further improve palliative care. Trial registration: Trial NL6408 (NTR6584). Registered in Netherlands Trial Register on June 30, 2017
