RESUMEN

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 reframing 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 reframing 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.

RESUMEN

INTRODUCTION: Communication about the palliative setting remains a barrier for many physicians because they are afraid to harm the patient by giving bad news. We sought to determine whether this a valid concern; the influence of prognostic understanding on patients' quality of life (QoL); and which factors influence this relationship. METHODS: The present multicenter, cross-sectional study used a questionnaire to measure patients' prognostic understanding, QoL, mood, and coping strategy. RESULTS: We surveyed 125 patients with advanced lung cancer. Prognostic understanding correlated significantly with emotional well-being (r = -0.20; P = .01) and pain (r = 0.43; P = .00) but not with anxiety (r = 0.12, P = .12) or depression (r = 0.05; P = .29). Patients with anxiety (r = -0.23; P = .01) and patients with depressive feelings (r = -0.63; P = .00) experienced poorer QoL. Four in 10 patients reported feelings of anxiety and/or depression. Positive reframing as a coping strategy was associated with a better QoL (r = 0.25; P = .00). CONCLUSION: Prognostic understanding was related to poorer emotional well-being and more pain but does not affect mood. Four in 10 patients reported feelings of anxiety and/or depression, which were associated with a poorer QoL. A holistic approach seems necessary when physicians communicate about the palliative setting.

RESUMEN

A multicenter study was performed to determine an optimal workflow for liquid biopsy in a clinical setting. In total, 549 plasma samples from 234 non-small cell lung cancer (NSCLC) patients were collected. Epidermal Growth Factor Receptor (EGFR) circulating cell-free tumor DNA (ctDNA) mutational analysis was performed using digital droplet PCR (ddPCR). The influence of (pre-) analytical variables on ctDNA analysis was investigated. Sensitivity of ctDNA analysis was influenced by an interplay between increased plasma volume (p < 0.001) and short transit time (p = 0.018). Multistep, high-speed centrifugation both increased plasma generation (p < 0.001) and reduced genomic DNA (gDNA) contamination. Longer transit time increased the risk of hemolysis (p < 0.001) and low temperatures were shown to have a negative effect. Metastatic sites were found to be strongly associated with ctDNA detection (p < 0.001), as well as allele frequency (p = 0.034). Activating mutations were detected in a higher concentration and allele frequency compared to the T790M mutation (p = 0.003, and p = 0.002, respectively). Optimization of (pre-) analytical variables is key to successful ctDNA analysis. Sufficient plasma volumes without hemolysis or gDNA contamination can be achieved by using multistep, high-speed centrifugation, coupled with short transit time and temperature regulation. Metastatic site location influenced ctDNA detection. Finally, ctDNA levels might have further value in detecting resistance mechanisms.

RESUMEN

BACKGROUND: Implementation of early palliative care (EPC) into daily oncology practice remains difficult. One of the barriers preventing oncologists from starting EPC is open communication about the palliative setting. The aim of this study was to investigate the relevance of this communication barrier. PATIENTS AND METHODS: In this cross-sectional multicenter study, 106 patients with advanced thoracic cancer were issued a questionnaire to survey 3 dimensions of interest: illness understanding, observation of conversation regarding prognosis and end-of-life (EoL) care, and information preferences of the patients. RESULTS: Only 45% of subjects were aware that their treatment was not curative. When comparing presumed treatment goals between patients who were aware that their treatment could not cure them and patients likely to think that their treatment could cure them, 39% of the former chose quality of life versus 9% of the latter, whereas 36% of the former chose cure versus 13% of the latter (χ2 = 17.7, P = .001). Seventy-five percent never had a conversation about EoL care. More than 50% found a discussion about prognosis and EoL care to be very important. CONCLUSION: This study reveals the existence of a communication barrier and underlines the importance of sustained emphasis with regard to the palliative intent of the treatment. Patients who are aware that they could not be cured were more aware of the primary goal of their treatment, namely quality of life. Most patients did not discuss prognosis and EoL care despite their wish for such a communication.

RESUMEN

OBJECTIVE: Remediastinoscopy is a valuable tool in restaging non-small cell lung cancer after induction therapy for mediastinal nodal involvement as it provides pathological evidence of response and may select patients for subsequent thoracotomy. However, long-term survival data after remediastinoscopy are scarce. METHODS: From November 1994 to April 2003, a remediastinoscopy was performed in 32 patients (29 men, 3 women) after induction therapy for locally advanced non-small cell lung cancer. Mean age was 67.8 years (range, 47-83). Neoadjuvant chemotherapy was given in 26 patients and chemoradiotherapy in 6. Follow-up data were completed in January 2005. RESULTS: Remediastinoscopy was technically feasible in all patients. There were five false-negative remediastinoscopies, resulting in a sensitivity of 71%, specificity of 100% and accuracy of 84%. Follow-up was complete in all patients. Median survival time for the whole group was 21 months (95% confidence interval [CI] 9-33). Median survival time in patients with a positive remediastinoscopy was 7 months (95% CI 5-9), with a negative remediastinoscopy 41 months (95% CI 13-69), and with a false-negative remediastinoscopy 24 months (95% CI 5-43). The difference between positive and negative remediastinoscopies was highly significant (p=0.003). In the combined group of patients with positive and false-negative remediastinoscopies (n=17), median survival time was 8 months (95% CI 3-13). The difference with negative remediastinoscopy remained significant (p=0.012). In a multivariate analysis, including sex, age, histology and nodal status at repeat mediastinoscopy, only nodal status was a significant independent prognostic factor (p=0.015). CONCLUSIONS: Remediastinoscopy is a valuable restaging procedure after induction therapy. Prognosis is poor in patients with persisting mediastinal nodal involvement, proven at repeat mediastinoscopy.
