Overall Survival after Radiotherapy for Brain Metastases According to ECOG Status-A Prospective Study of 294 NSCLC Patients.

Up to 40% of non-smallcell lung cancer (NSCLC) patients develop brain metastases (BMs). The potential benefits of radiotherapy (RT) in patients with poor performance status (PS) are questionable, with considerable risk for futile treatment. We analyzed overall survival after initial radiotherapy in NSCLC patients with BMs, focusing on the relationship between PS and survival after RT. This study reports a prospective observational study including consecutive 294 NSCLC patients with first-time BMs. Overall survival (OS) was calculated from the start of RT to death or last follow-up (1 June 2023). Overall, in the 294 included patients (median age 69 years), the median OS was 4.6 months; 2.5 months after WBRT (n = 141), and 7.5 months after SRT (n = 153). After WBRT, mOS was equally poor for patients with ECOG 2 (1.9 months) and ECOG 3-4 (1.2 months). After SRT, mOS for patients with ECOG 2 was 4.1 months; for ECOG 3 patients, mOS was 4 1.6 months. For NSCLC patients with ECOG 2 diagnosed with BMs who are not candidates for surgery or SRT, WBRT should be questioned due to short survival.

PALLiative care in ONcology (PALLiON): A cluster-randomised trial investigating the effect of palliative care on the use of anticancer treatment at the end of life.

BACKGROUND: Effects on anticancer therapy following the integration of palliative care and oncology are rarely investigated. Thus, its potential effect is unknown. AIM: To investigate the effects of the complex intervention PALLiON versus usual care on end-of-life anticancer therapy. DESIGN: Cluster-randomised controlled trial (RCT), registered at ClinicalTrials.gov (No. NCT01362816). The complex intervention consisted of a physician education program enhancing theoretical, clinical and communication skills, a patient-centred care pathway and patient symptom reporting prior to all consultations. Primary outcome was overall use, start and cessation of anticancer therapy in the last 3 months before death. Secondary outcomes were patient-reported outcomes. Mixed effects logistic regression models and Cox proportional hazard were used. SETTING: A total of 12 Norwegian hospitals (03/2017-02/2021). PARTICIPANTS: Patients ⩾18 years, advanced stage solid tumour, starting last line of anticancer therapy, estimated life expectancy ⩽12 months. RESULTS: A total of 616 (93%) patients were included (intervention: 309/control:307); 63% males, median age 69, 77% had gastrointestinal cancers. Median survival time from inclusion was 8 (IQR 3-14) and 7 months (IQR 3-12), and days between anticancer therapy start and death were 204 (90-378) and 168 (69-351) (intervention/control). Overall, 78 patients (13%) received anticancer therapy in the last month (intervention: 33 [11%]/control: 45 [15%]). No differences were found in patient-reported outcomes. CONCLUSION: We found no significant differences in the probability of receiving end-of-life anticancer therapy. The intervention did not have the desired effect. It was probably too general and too focussed on communication skills to exert a substantial influence on conventional clinical practice.

A complex communication skills training program for physicians providing advanced cancer care - content development and barriers and solutions for implementation.

Background: Early integration of oncology and patient-centered palliative care is the recommended clinical practice model for patients with advanced cancer. General and specific communication skills are necessary to achieve integrated patient-centered care, but require organized training to be adequately mastered. Challenges and barriers on several levels, i.e. organizational, professional and individual may, however, hamper implementation. The development, implementation, and evaluation of such an educational program focusing on communication skills contain many steps, considerations and lessons learned, which are described in this article.Methods: A multi-professional faculty developed, implemented, and evaluated an educational program through a 5-step approach. The program was part of a Norwegian cluster-randomized controlled trial aiming to test the effect of early integration of oncology and palliative care for patients with advanced cancer.Results: The result is the PALLiON educational program; a multi-faceted, evidence-based, and learner-centered program with a specific focus on physicians' communication skills. Four modules were developed: lectures, discussion groups, skills training, and coaching. These were implemented at the six intervention hospitals using different teaching strategies. Evaluation in a subgroup of participants showed a positive appraisal of the group discussions and skills training.Conclusion:We present our experiences and reflections regarding implementation and lessons learned, which should be considered in future developments and implementations; (1) Include experienced faculty with various backgrounds, (2) Be both evidence-based and learner-centered, (3) Choose teaching strategies wisely, (4) Expect resistance and skepticism, (5) Team up with management and gatekeepers, (6) Expect time to fly, and (7) Plan thorough assessment of the evaluation and effect.Trial registration: ClinicalTrials.gov identifier: NCT03088202.

Inflammatory Markers and Radiotherapy Response in Patients With Painful Bone Metastases.

CONTEXT: Inflammation is proposed to influence tumor response in radiotherapy (RT). Clinical studies to investigate the relationship between inflammatory markers and RT response is warranted to understand the variable RT efficacy in patients with painful bone metastases. OBJECTIVES: To evaluate the association between inflammatory markers and analgesic response to RT in patients with painful bone metastases. METHODS: Adult patients from 7 European study sites undergoing RT for painful bone metastases were included in this prospective and longitudinal analysis. The association between RT response and 17 inflammatory markers at baseline, as well as the association between RT response and the changes observed in inflammatory markers between baseline and three and eight weeks after RT, was analyzed with univariate regression analyses. Baseline analyses were adjusted for potential clinical predictors of RT response. RESULTS: None of the inflammatory markers were significantly associated with an upcoming RT response in the analysis of 448 patients with complete baseline data. In patients available for follow-up, the three-week change in TNF (P 0.017), IL-8 (P 0.028), IP-10 (P 0.032), eotaxin (P 0.043), G-CSF (P 0.033) and MCP-1 (P 0.002) were positively associated with RT response, while the three-week change in CRP (P 0.006) was negatively associated. CONCLUSION: Results from this study show an association between RT response and change in pro-inflammatory mediators and indicate that inflammation may be important to achieve an analgesic RT response in patients with painful bone metastases. None of the investigated inflammatory markers were found to be pre-treatment predictors of RT response.

Integration of palliative care in oncology-the intersection of cultures and perspectives of oncology and palliative care.

Palliative care complements anti-cancer treatment, and may actually improve the therapeutic effect by optimising performance status, functioning, symptom management and quality of life, thus improving compliance to treatment. A series of randomised controlled trials investigating early integration of palliative care and oncology document clear benefits in patient-centred outcomes. Still, palliative care is often introduced late in the disease trajectory, if at all. One reason may be that that palliative care is perceived as end-of-life care only, a too common perception among healthcare providers, patients and the public alike. Another, and maybe the most important, reason is the cultural differences between the two disciplines, oncology and palliative care. While the predominant focus in oncology is treatment and cure of the disease, i.e., a tumour-centred focus, the focus in palliative care is the patient with the disease, i.e., the patient-centred approach. Integration of oncology and palliative care implies that these two cultures approach each other, collaborate and recognise that this is not an either or, but time to collaborate with the best interest of the patients. To accomplish this, an organisational model to provide optimal patient-centred palliative care is necessary at all levels. Such a model must structure the collaborations between different professions, across different levels and the patient flow between the silos in healthcare, and should describe the content of care. Using models like this is not common, and requires changes in systems and cultures on organisational, administrative, educational and individual levels. To successfully achieve profound changes is challenging. For example, it may be hampered by professional autonomy in the different disciplines and hinder collaboration and the achievement of a shared mental model. The use of standardised care pathways may be one way to integrate the tumour-centred and patient-centred approaches, reduce cultural barriers and improve patient care.

Surgery for brain metastases-impact of the extent of resection.

BACKGROUND: Surgical resection of brain metastases improves symptoms and survival in selected patients. The benefit of gross total resection is disputed, as most patients are believed to succumb from their non-CNS tumor burden. We investigated the association between overall survival and residual tumor after surgery for single brain metastases. METHODS: We reviewed adults who underwent surgery for a single brain metastasis at a regional referral center (2011-2018). Gross total resection was defined as no visible residual tumor on cerebral MRI 12-48 h postoperatively. RESULTS: We included 373 patients. The most common primary tumors were lung cancer (36%) and melanoma (24%). We identified gross total resection in 238 patients (64%). Median overall survival was 11.0 months, 8.0 (6.2-9.8) months for patients with subtotal resection and 13.0 (9.7-16.3) months for patients with gross total resection. In a multivariate regression analysis including preoperative prognostic factors, gross total resection was associated with longer overall survival (HR: 0.66, p = 0.003). Postoperative radiotherapy administered within 6 weeks did not significantly alter the hazard ratio estimates for grade of resection. CONCLUSIONS: Our study suggests improved survival with gross total resection compared to subtotal resection. The importance of extent of resection in surgery for brain metastases should not be discarded.

Benefits of Study Participation for Patients with Advanced Cancer Receiving Radiotherapy: A Prospective Observational Study.

Background: Patients with advanced cancer and bone metastases may have unmet palliative care (PC) needs that go unnoticed during clinical oncological practice. This observational study describes interventions that were initiated as the patients participated in the Palliative Radiotherapy and Inflammation Study (PRAIS). It was hypothesized that the patients would benefit from study participation due to PC interventions initiated by the study team. Methods: A retrospective review of patients' electronic records. Patients with advanced cancer and painful bone metastases included in PRAIS were eligible. All patients met with the study team before start of radiotherapy, after completion of Patient Reported Outcome Measures. Interventions initiated by the study team were documented in the patients' electronic records. Results: A total of 133 patients were reviewed: 63% males, mean (standard deviation [SD]) age 65 (9.6) and mean (SD) Karnofsky performance status (KPS) score 73.2 (9.1). Interventions were initiated in 50% (n = 67) of the patients. Changes in opioid management (69%), treatment of constipation (43%), and nausea (24%) and nutritional advice were most frequent (21%). Patients receiving interventions had lower mean KPS (70 vs. 77 p < 0.001), shorter survival time after study inclusion (median 28 vs. 57.5 weeks p = 0.005) and were more often opioid naïve (12% vs. 39% p < 0.001) than those not receiving interventions by the study team. Conclusions: Patients with advanced cancer and painful bone metastasis benefited from study participation due to multiple PC interventions initiated by the study team. The findings call for a systematic integration of PC in patients with advanced cancer. Trial Registration: ClinicalTrials.gov NCT02107664.

Using Process Indicators to Monitor Documentation of Patient-Centred Variables in an Integrated Oncology and Palliative Care Pathway-Results from a Cluster Randomized Trial.

BACKGROUND: Despite robust evidence from randomized controlled trials (RCTs) demonstrating clinical and patient-reported benefits of integrated oncology and palliative care, the tumour-centred focus is predominant. This single-centre process evaluation monitors documentation of required patient-centred variables during an RCT. METHODS: Performance status, patient self-reported symptoms, weight and summaries to general practitioners were assessed from June 2017 to July 2020 in three consultation types: first oncological after study inclusion and palliative and oncological consultations during chemotherapy. Descriptive statistics were used to monitor if the pre-defined program fulfilment of ≥85% documentation was reached. RESULTS: 435 consultations were monitored in 76 patients; 60.5% males, 86.8% with GI cancers; 76 (17.5%) were from the first oncological consultations, 87 (20.0%) and 272 (62.5%) from palliative or subsequent oncological consultations. Program fulfilment differed across consultation types with 94.8% in the palliative consultations (83.3-100%), relative to 65.8% (62.5-75.0%) and 69.2% (57.0-84.3%) for first and subsequent oncological consultations over time, respectively. Use of self-reported symptoms was consistently lower in the oncological consultations. CONCLUSIONS: The documentation level of required core variables was not satisfactory, notwithstanding their high clinical relevance and continuous reminders during study. Pre-trial optimization strategies are paramount to promote integration and reduce professional and personal barriers towards a more patient-centred focus.

Overall survival after initial radiotherapy for brain metastases; a population based study of 2140 patients with non-small cell lung cancer.

BACKGROUND: Brain metastases (BM) occur in about 30% of all patients with non-small cell lung cancer (NSCLC). BM treatment guidelines recommend more frequent use of stereotactic radiotherapy (SRT). Overall, studies report no difference in overall survival (OS) comparing SRT to whole-brain radiotherapy (WBRT). We examined survival after radiotherapy for BM in a population-based sample from the South-Eastern Norway Regional Health Authority treated 2006-2018. METHODS: We reviewed electronic medical records of 2140 NSCLC patients treated with SRT or WBRT for BM from 2006-2018. Overall survival (OS) was compared to predicted survival according to the prognostic systems DS-GPA and Lung-molGPA. RESULTS: Use of SRT increased during the period, from 19% (2006-2014) to 45% (2015-2018). Median OS for all patients was 3.0 months, increasing from 2.0 (2006) to 4.0 (2018). Median OS after SRT was 7.0 months (n = 435) and 3.0 months after WBRT (n = 1705). Twenty-seven percent of SRT patients and 50% of WBRT patients died within 90 days after start of RT. Age ≥70, male sex, KPS ≤70, non-adenocarcinoma histology, ECM present, multiple BM, and WBRT were associated with shorter survival (p < .001). Actual mOS corresponded best with predicted mOS by DS-GPA and Lung-molGPA for the SRT group. CONCLUSION: Overall survival after radiotherapy (RT) for BM improved during the study period, but only for patients treated with SRT. Survival after WBRT remains poor; its use should be questioned. DS-GPA and Lung-molGPA seem most useful in predicting prognosis considered for SRT.

Surgery for brain metastases - real-world prognostic factors' association with survival.

BACKGROUND: Surgical resection of brain metastases (BM) improves overall survival (OS) in selected patients. Selecting those patients likely to benefit from surgery is challenging. The Graded Prognostic Assessment (GPA) and the diagnosis-specific Graded Prognostic Assessment (ds-GPA) were developed to predict survival in patients with BM, but not specifically to guide patient selection for surgery. Our aim was to evaluate the feasibility of preoperative GPA/ds-GPA scores and assess variables associated with OS. METHODS: We retrospectively reviewed first-time surgical resection of BM from solid tumors at a Norwegian regional referral center from 2011 to 2018. RESULTS: Of 590 patients, 51% were female and median age was 63 years. Median OS was 10.3 months and 74 patients (13%) died within three months after surgery. Preoperatively tumor origin was unknown in 20% of patients. A GPA score could be calculated for 92% of the patients preoperatively, but could not correctly predict survival. A ds-GPA score could be calculated for 46% of patients. Multivariable regression analysis revealed shorter OS in patients with higher age, worse functioning status, colorectal primary cancer compared to lung cancer, presence of extracranial metastases, and more than four BM. Patients with preoperative progressive extracranial disease or synchronous BM had shorter OS compared to patients with stable extracranial disease. CONCLUSION: Ds-GPA could be calculated in less than half of patients preoperatively and GPA poorly identified patients which had minimal benefit of surgery. Including status of extracranial disease improve prognostication and therefore selection to surgery for brain metastases.

Clinical Predictors for Analgesic Response to Radiotherapy in Patients with Painful Bone Metastases.

BACKGROUND: Radiotherapy (RT) reduces pain in about 60% of patients with painful bone metastases, leaving many patients without clinical benefit. This study assesses predictors for RT effectiveness in patients with painful bone metastases. MATERIALS AND METHODS: We included adult patients receiving RT for painful bone metastases in a multicenter, multinational longitudinal observational study. Pain response within 8 weeks was defined as ≥2-point decrease on a 0-10 pain score scale, without increase in analgesics; or a decrease in analgesics of ≥25% without increase in pain score. Potential predictors were related to patient demographics, RT administration, pain characteristics, tumor characteristics, depression and inflammation (C-reactive protein [CRP]). Multivariate logistic regression analysis with multiple imputation of missing data were applied to identify predictors of RT response. RESULTS: Of 513 eligible patients, 460 patients (90 %) were included in the regression model. 224 patients (44%, 95% confidence interval (CI) 39%-48%) responded to RT. Better Karnofsky performance status (Odds ratio (OR) 1.39, CI 1.15-1.68), breast cancer (OR 2.54, CI 1.12-5.73), prostate cancer (OR 2.83, CI 1.27-6.33) and soft tissue expansion (OR 2.00, CI 1.23-3.25) predicted RT response. Corticosteroids were a negative predictor (OR 0.57, CI 0.37-0.88). Single and multiple fraction RT had similar response. The discriminative ability of the model was moderate; C-statistic 0.69. CONCLUSION: This study supports previous findings that better performance status and type of cancer diagnosis predicts analgesic RT response, and new data showing that soft tissue expansion predicts RT response and that corticosteroids is a negative predictor for RT response in patients with painful bone metastases.

Use of radiotherapy in breast cancer patients with brain metastases: a retrospective 11-year single center study.

AIM: To analyse the use of radiotherapy (RT) and factors affecting overall survival (OS) after RT in breast cancer patients with brain metastases. METHODS: Breast cancer patients treated from 2008 to 2018 with whole brain RT (WBRT) or stereotactic radiosurgery (SRS) at a large regional cancer referral center were identified from the hospital's RT register. Clinical variables were extracted from medical records. OS was calculated from date of first RT until death or last follow up. Potential factors affecting OS were analyzed. RESULTS: 255 females with WBRT (n = 206) or SRS (n = 49) as first RT were included. An increased use of initial SRS was observed in the second half of the study period. The most common WBRT fractionation regimen was 3 Gy × 10. SRS was most often single fractions; 18 or 25 Gy between 2009 and 2016, while fractionated SRS was mostly used in 2017 and 2018. Median OS in the WBRT group was 6 months (CI 1-73) relative to 23 (CI 0-78) in the SRS group. Age, performance status, initial RT technique, extracranial disease, brain metastasis surgery, number of brain metastases and DS-GPA score had significant impact on OS. Only ECOG 0 and brain metastasis surgery were associated with superior OS in multivariate analysis. CONCLUSION: WBRT was the most frequent primary RT. An increased use of initial SRS was observed in the second half of the study period. Only ECOG 0 and brain metastasis surgery were associated with superior OS in multivariate analysis.

The short-term impact of methylprednisolone on patient-reported sleep in patients with advanced cancer in a randomized, placebo-controlled, double-blind trial.

PURPOSE: Although corticosteroids are frequently used in patients with advanced cancer, few studies have examined the impact of these drugs on patient-reported sleep. We aimed to examine the short-term impact of methylprednisolone on patient-reported sleep in patients with advanced cancer. METHODS: Patient-reported sleep was a predefined secondary outcome in a prospective, randomized, placebo-controlled, double-blind trial that evaluated the analgesic efficacy of corticosteroids in advanced cancer patients (18+), using opioids, and having pain ≥ 4 past 24 h (NRS 0-10). Patients were randomized to the methylprednisolone group with methylprednisolone 16 mg × 2/day or placebo for 7 days. The EORTC QLQ-C30 (0-100) and the Pittsburgh Sleep Quality Index questionnaire (PSQI) (0-21) were used to assess the impact of corticosteroids on sleep at baseline and at day 7. RESULTS: Fifty patients were randomized of which 25 were analyzed in the intervention group and 22 in the control group. Mean age was 64 years, mean Karnofsky performance status was 67 (SD 13.3), 51% were female, and the mean oral daily morphine equivalent dose was 223 mg (SD 222.77). Mean QLQ-C30 sleep score at baseline was 29.0 (SD 36.7) in the methylprednisolone group and 24.2 (SD 27.6) in the placebo group. At day 7, there was no difference between the groups on QLQ-C30 sleep score (methylprednisolone 20.3 (SD 32.9); placebo 28.8 (SD 33.0), p = 0.173). PSQI showed similar results. CONCLUSIONS: Methylprednisolone 16 mg twice daily for 7 days had no impact on patient-reported sleep in this cohort of patients with advanced cancer. TRIAL REGISTRATION: Clinical trial information NCT00676936 (13.05.2008).

PALLiON - PALLiative care Integrated in ONcology: study protocol for a Norwegian national cluster-randomized control trial with a complex intervention of early integration of palliative care.

BACKGROUND: Several publications have addressed the need for a systematic integration of oncological care focused on the tumor and palliative care (PC) focused on the patient with cancer. The exponential increase in anticancer treatments and the high number of patients living longer with advanced disease have accentuated this. Internationally, there is now a persuasive argument that introducing PC early during anticancer treatment in patients with advanced disease has beneficial effects on symptoms, psychological distress, and survival. METHODS: This is a national cluster-randomized trial (C-RCT) in 12 Norwegian hospitals. The trial investigates effects of early, systematic integration of oncology and specialized PC in patients with advanced cancer in six intervention hospitals compared with conventional care in six. Hospitals are stratified on the size of local catchment areas before randomization. In the intervention hospitals, a three-part complex intervention will be implemented. The backbone of the intervention is the development and implementation of patient-centered care pathways that contain early, compulsory referral to PC and regular and systematic registrations of symptoms. An educational program must be completed before patient inclusion. A total of 680 patients with advanced cancer and one caregiver per patient are included when patients come for start of last line of chemotherapy, defined according to national treatment guidelines. Data registration, clinical variables, and patient- and caregiver-reported outcomes take place every 2 months for 1 year or until death. The primary outcome is use of chemotherapy in the last 3 months of life by comparing the proportion of patients who receive this in the intervention and control groups. Primary outcome is use of chemotherapy in the last 3 months before death, i.e. number of patients. Secondary outcomes are initiation, discontinuation and number of cycles, last 3 months of life, administration of other medical interventions in the last month of life, symptom burden, quality of life (QoL), satisfaction with information and follow-up, and caregiver health, QoL, and satisfaction with care. DISCUSSION: Results from this C-RCT will be used to raise the awareness about the positive outcomes of early provision of specialized palliative care using pathways for patients with advanced cancer receiving medical anticancer treatment. The long-term clinical objective is to integrate these patient-centered pathways in Norwegian cancer care. The specific focus on the patient and family and the organization of a predictable care trajectory is consistent with current Norwegian strategies for cancer care. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03088202. Registered on 23 March 2017.

Challenges and Learning Needs for Providers of Advanced Cancer Care: Focus Group Interviews with Physicians and Nurses.

Background: Implementation of integrated oncology and palliative care improves patient outcomes but may represent a demanding task for health care providers (HCPs). Objective: To explore physicians' and nurses' perceived challenges and learning needs in their care for patients with advanced cancer, and to analyze how these perceptions can provide insight on how to improve care for patients with advanced cancer in an integrated care model. Methods: Residents in oncology, oncologists, nurses, and palliative care physicians were recruited to participate in focus group interviews. Six focus group interviews were conducted with 35 informants. Data were analyzed according to principles of thematic analysis. Results: The discussions in the interviews concerned three broad themes: an emphasis on patients' best interest, perceived as hindered by two sets of barriers; unsatisfactory organizational conditions such as time pressure, lack of referral routines, and few arenas for interdisciplinary collaboration, was perceived as one barrier. The other barrier was related to the appraisal of other HCPs' clinical practices. Participating HCPs expressed in general a positive self-view, but were more critical of other HCPs. Conclusion: Currently, implementation of measures to improve care for patients with advanced cancer appears to be challenging due to cultural and organizational factors, and how HCPs perceive themselves and other HCPs. HCPs' perception of challenges in patient care as not related to themselves (externalization) might be an essential obstacle. Interventions targeting both HCP-related and organizational factors are needed. Particularly important are measures aimed at reducing fragmentation and improving collaboration in care.

Patients with advanced cancer and depression report a significantly higher symptom burden than non-depressed patients.

OBJECTIVE: Clinical observations indicate that patients with advanced cancer and depression report higher symptom burden than nondepressed patients. This is rarely examined empirically. Study aim was to investigate the association between self-reported depression disorder (DD) and symptoms in patients with advanced cancer controlled for prognostic factors. METHOD: The sample included 935 patients, mean age 62, 52% males, from an international multicentre observational study (European Palliative Care Research Collaborative - Computerised Symptom Assessment and Classification of Pain, Depression and Physical Function). DD was assessed by the Patient Health Questionnaire-9 and scored with Diagnostic and Statistical Manual of Mental Disorder-5 algorithm for major depressive disorder, excluding somatic symptoms. Symptom burden was assessed by summing scores on somatic Edmonton Symptom Assessment Scale (ESAS) symptoms, excluding depression, anxiety, and well-being. Item-by-item scores and symptom burden of those with and without DD were compared using nonparametric Mann-Whitney U tests. The relative importance of sociodemographic, medical, and prognostic factors and DD in predicting symptom burden was assessed by hierarchical, multiple regression analyses. RESULT: Patients with DD reported significantly higher scores on ESAS items and a twofold higher symptom burden compared with those without. Factors associated with higher symptom burden were as follows. Diagnosis: lung (ß = 0.15, p < 0.001) or breast cancer (ß = 0.08, p < 0.05); poorer prognosis: high C-reactive protein (ß = 0.08, p < 0.05), lower Karnofsky Performance Status (ß = -0.14, p < 0.001), and greater weight loss (ß = -0.15, p < 0.001); taking opioids (ß = 0.11, p < 0.01); and having DD (ß = 0.23, p < 0.001). The full model explained 18% of the variance in symptom burden. DD explained 4.4% over and above that explained by all the other variables. SIGNIFICANCE OF RESULTS: Depression in patients with advanced cancer is associated with higher symptom burden. These results encourage improved routines for identifying and treating those suffering from depression.

A comparison of CT based measures of skeletal muscle mass and density from the Th4 and L3 levels in patients with advanced non-small-cell lung cancer.

BACKGROUND: Muscle mass and density assessed from CT-images at the L3 level are prognostic for survival and predict toxicity in cancer patients. However, L3 is not always included on routine CT-scans. We aimed to investigate whether images at the Th4 level may be used instead. METHODS: Patients from three chemotherapy trials in advanced NSCLC were eligible (n = 1305). Skeletal muscle area (cm2), skeletal muscle index (SMI, cm2/m2) and skeletal muscle density (SMD) at Th4 and L3 levels were assessed from baseline CT-scans. SMI and SMD at the Th4 and L3 level were transformed into z-scores and the agreement between scores was investigated by Bland-Altman plots and estimated by intra-class correlation analyses. Linear regression was used to test if Th4 SMI and SMD z-scores predicted L3 SMI and SMD z-scores. RESULTS: CT-images from 401 patients were analysable at both levels. There was a moderate agreement between Th4 and L3 SMI z-scores with an intra-class correlation of 0.71 (95% CI 0.64-0.77) for men and 0.53 (95% CI 0.41-0.63) for women. Regression models predicting L3 SMI z-scores from Th4 SMI z-scores showed coefficients of 0.71 (95% CI 0.62-0.80) among men and 0.53 (95% CI 0.40-0.66) among women. R-squares were 0.51 and 0.28, respectively, indicating moderate agreement. A similar, moderate agreement between Th4 and L3 SMD z-scores was observed. CONCLUSION: There was only moderate agreement between muscle measures from Th4 and L3 levels, indicating that missing data from the L3 level cannot be replaced by analysing images at the Th4 level.
