Prognostic implications of cellular senescence in resected non-small cell lung cancer

Background: Cure and long-term survival for non-small cell lung cancer (NSCLC) remains hard to achieve. Cellular senescence, an emerging hallmark of cancer, is considered as an endogenous tumor suppressor mechanism. However, senescent cancer cells can paradoxically affect the surrounding tumor microenvironment (TME), ultimately leading to cancer relapse and metastasis. As such, the role of cellular senescence in cancer is highly controversial. Methods: In 155 formalin-fixed paraffin-embedded (FFPE) samples from surgically resected NSCLC patients with pathological tumor-node-metastasis (pTNM) stages I-IV (8th edition), cellular senescence was assessed using a combination of four immunohistochemical senescence markers, i.e., lipofuscin, p16INK4a, p21WAF1/Cip1 and Ki67, and correlated to clinicopathological parameters and outcomes, including overall survival (OS) and disease-free survival (DFS). Results: A tumoral senescence signature (SS) was present in 48 out of 155 NSCLC patients, but did not correlate to any clinicopathological parameter, except for p53 mutation status. In a histologically homogenous patient cohort of 100 patients who fulfilled the following criteria: (I) one type of histology, i.e., adenocarcinoma, (II) without known epidermal growth factor receptor (EGFR) mutation, (III) curative (R0) resection and (IV) no neoadjuvant systemic therapy or radiotherapy, the median OS and DFS for patients with a tumoral SS (n=30, 30.0%) compared to patients without a tumoral SS (n=70, 70.0%) was 53 versus 141 months (P=0.005) and 45 versus 55 months (P=0.25), respectively. In multiple Cox proportional hazards (Cox PH) model analysis correcting for age, pTNM stage I-III and adjuvant therapy, a tumoral SS remained a significant prognostic factor for OS (HR =2.03; P=0.014). Conclusions: The presence of a tumoral SS particularly based on high p16INK4a expression significantly affects OS in NSCLC adenocarcinoma. In this light, adjuvant senolytic therapy could be an interesting strategy for NSCLC patients harboring a tumoral SS, ultimately to improve survival of these patients

Communication skills training in advance care planning : a survey among medical students at the University of Antwerp

BACKGROUND: Palliative care (PC) is a strongly emerging discipline worldwide. Despite efforts to integrate this important topic in the medical curriculum in Belgium, still little time is spent on PC and its implementation during theoretical and practical training. MATERIALS & METHODS: We had two cohorts of second master’s year MD students at the University of Antwerp complete a survey compromising a custom-built PC knowledge test and a self-confidence assessment of communicative skills used in end-of-life conversations. We evaluated students’ self-confidence regarding end-of-life-conversations before and after a PC training program. We also explored whether the PC classes enabled the students to adequately reflect on factors that might influence end-of-life conversations with an open-end question about the potential implications of the COVID-19 pandemic on advance care planning (ACP) conversations. Finally, we compared the results of the respondents having enjoyed face-to-face training (cohort 1) with those having received online training only (cohort 2, COVID-19 pandemic). RESULTS: Although the respondents in both cohorts indicated that the overall curriculum did not pay enough attention to PC training, their average scores on the theoretical questions were good. Feeling confident about their communicative skills in general, they indicated to be less confident when it came to communications concerning PC and ACP in particular. The COVID-19 pandemic was initially equally deemed to impede and facilitate ACP and end-of-life conversations, but after the ACP training class more respondents saw the pandemic as an opportunity to broach end-of-life issues. Finally, we found no differences in scores between online and regular classroom teaching. CONCLUSION: Students experience a lack of confidence in communication skills used in end-of-life conversations and ACP. To help improve skills and competencies in conducting end-of-life conversations, it is recommended to have medical students assess PC/ACP training programs regularly and to modify the curriculum and course content based on these outcomes and current developments.

Do-Not-ResuscitateDecision-making during the COVID-19 pandemic in a teaching hospital : lessons learned for the future

Abstract: Rationale. Contribute to the understanding of DNR decision-making and conducting end-of-life conversations, about which there is a paucity of data available in the current literature. Aims and Objectives. Assess how the decision-making process to determine a DNR code is implemented in the day-to-day clinical practice in a tertiary teaching hospital. Familiarity with the use of different scores as a possible objective support for DNR decisions and the influence of various elements on a DNR decision was explored. Method. A cross-sectional survey study was conducted between February 2021 and April 2021 for all doctors and doctors in training, working in the Antwerp University Hospital during the COVID-19 pandemic. Results. 127 doctors participated in this study. The familiarity with the different scores used in the triage during the COVID-10 pandemic was 51% for the Clinical Frailty Scale (CFS) and 20% for the Charlson Comorbidity Index (CCI). Participants indicated that their DNR decision is based on various aspects such as clinical assessment, comorbidities, patient\u2019s wishes, age, prognosis, and functional state. Conclusion. The familiarity with the different scores used during triage assessments is low. The total clinical picture of the patient is needed to make a considered decision, and this total picture of the patient seems to be well encompassed by frailty measurement (CFS). Although many participants indicated that the different scores do not offer much added value compared to their clinical assessment, it can help guide DNR decisions, especially for doctors in training

New implications of patients' sex in today's lung cancer management

SIMPLE SUMMARY: We aim to raise awareness that sex is an important factor to take into account in modern-day thoracic oncology practice. Summarized, women should be specifically targeted in smoking cessation campaigns and sex-specific barriers should be addressed. Women present more often with adenocarcinoma histology and EGFR/ALK alterations, as lung cancer in never-smokers is more common in women compared to men. Lung cancer in female patients may show a poorer response to immune checkpoint inhibition; therefore, the addition of chemotherapy should be considered. On the other hand, women experience more benefits from targeted therapy against EGFR. In general, prognosis for women is better compared to that in men. Lung cancer screening trials report that women derive more benefit from screening, although they have not been designed for women. Future trial designs should take this into account and encourage participation of women. ABSTRACT: This paper describes where and how sex matters in today’s management of lung cancer. We consecutively describe the differences between males and females in lung cancer demographics; sex-based differences in the immune system (including the poorer outcomes in women who are treated with immunotherapy but no chemotherapy); the presence of oncogenic drivers and the response to targeted therapies according to sex; the greater benefit women derive from lung cancer screening and why they get screened less; and finally, the barriers to smoking cessation that women experience. We conclude that sex is an important but often overlooked factor in modern-day thoracic oncology practice

Coping strategy influences quality of life in patients with advanced lung cancer by mediating mood

Patients with advanced lung cancer and depressive/anxiety symptoms experience worse quality of life (QoL) We examined whether and how coping strategy influenced QoL in these patients. A multicenter cross-sectional study of 125 patients with advanced lung cancer was conducted. Patients using positive reframing as coping strategy, experience less anxiety and depressive symptoms leading to a better QoL. Introduction: Patients with advanced lung cancer experience high physical symptom burden with substantial psychological distress. Depressive and anxiety symptoms are common and associated with worse quality of life (QoL). Early palliative care (EPC) addresses the complex supportive care needs improving QoL and mood. The mechanisms of EPC are uncertain. We examined whether and how coping strategy, a primary component of EPC, influenced QoL in these patients. Materials and Methods: We conducted a multicenter cross-sectional study of patients with advanced lung cancer. A total of 125 patients completed assessments of QoL (QLQ-C15-PAL), depressive and anxiety symptoms (HADS), and coping (brief COPE questionnaire). The data were analyzed by descriptive statistics. To determine whether and how coping strategy influences QoL, correlations and logistic regressions were performed. Results: Positive refraining correlates significantly with global QoL (r 0.25, P <.01), emotional well-being (r= 0.33, P <.01), pain (r = 0.30, P <.01), fatigue (r = 0.22, P <.01), loss of appetite (r = 0.22, P <.01) and nausea (r = 0.24, P <.01). Self-blame correlates significantly with worse emotional well-being (r = 0.19, P <.05) and insomnia (r = 0.19, P <.05). Using a 4-step logistic regression model, it was found that anxiety and depressive symptoms fully mediated the relationship between positive reframing and QoL. Conclusions: Patients with advanced lung cancer using positive refraining as coping strategy, experience higher QoL. The mechanism behind it seems that positive reframing goes along with less anxiety and depressive symptoms leading to a better QoL. Self-blame leads to more insomnia and worse emotional well-being. Providing skills to cope effectively could impact QoL in these patients
