The prognostic impact of quality of life assessed with the EORTC QLQ-C30 in inoperable non-small cell lung carcinoma treated with radiotherapy

PURPOSE The purpose of this study was to assess the prognostic significance of pretreatment quality of life (QoL) scores and symptom scores in a group of patients treated with high dose radiotherapy. MATERIAL AND METHODS A total of 198 patients treated with external irradiation (>/=60 Gy) were included. In all these patients, baseline QoL was assessed using the EORTC QLQ-C30. The prognostic significance of a number of non-QoL and QoL parameters with regard to survival was estimated in both univariate and multivariate analyses. RESULTS In a multivariate model including the non-QoL parameters, performance status, weight loss and N-classification were independent prognostic factors for survival. After entering the QoL parameters in the model, global QoL was the strongest prognostic factor, while performance status lost its significance. Subsequently, a significant interaction term was found between N-classification and global QoL, indicating that global QoL was an independent prognostic factor but that the effect varied as a function of N-status. In N+ patients, the median survival in the group with low scores for global QoL was 4.5 months, which was significantly worse (P<0.0001) compared with the high score group in which the median survival was 12.9 months. CONCLUSION Global QoL is a strong prognostic factor for survival in patients with NSCLC who have pathological lymph nodes at presentation and who are treated with radical or curative radiotherapy.

Neurologic disorders in 432 consecutive patients with small cell lung carcinoma

Neurologic complications are an important cause of morbidity and possibly also mortality in patients with small cell lung carcinoma (SCLC). The current study was undertaken to prospectively investigate survival and the frequency of neurologic disorders in patients with SCLC.

Effects of medroxyprogesterone acetate on food intake, body composition, and resting energy expenditure in patients with advanced, nonhormone-sensitive cancer: a randomized, placebo-controlled trial.

Anorexia and cachexia are well‐known sequelae of cancer that contribute to morbidity and mortality. In several studies in patients with non‐hormone‐sensitive tumors, synthetic progestogens were shown to exert beneficial effects on appetite and weight loss. The current study was undertaken to investigate the effects of medroxyprogesterone acetate (MPA) on food intake, body composition, and resting energy expenditure (REE).

External irradiation versus external irradiation plus endobronchial brachytherapy in inoperable non-small cell lung cancer: a prospective randomized study.

Abstract Purpose : No randomized studies are available on the additional value of endobronchial brachytherapy (EBB) to external irradiation (XRT) regarding palliation of respiratory symptoms (RS). A prospective randomized study was initiated to test the hypothesis that the addition of EBB to XRT provides higher levels of palliation of dyspnea and other RS and improvement of quality of life (QoL) in patients with non-small cell lung cancer (NSCLC) with endobronchial tumour. Materials and methods : Patients with previously untreated NSCLC, stages I-IIIb, WHO-performance status of 0–3 and with biopsy proven endobronchial tumour in the proximal airways were eligible. EBB consisted of two fractions of 7.5 Gy at 1 cm on day 1 and 8. XRT started at day 2. The XRT dose was 30 Gy (2 weeks) or 60 Gy (6 weeks). The EORTC QLQ-C30 and QLQ-LC13 were assessed before treatment and 2 weeks, 6 weeks, 3, 6 and 12 months after treatment. Re-expansion of collapsed lung was tested by the inspiratory vital capacity (IVC) and CT scan of the chest. Results : Ninety-five patients were randomized between arm 1 (XRT alone) ( n =48) or arm 2 (XRT+EBB) ( n =47). The arms were well balanced regarding pre-treatment characteristics and QoL scores. The compliance for QoL-assessment was >90% at all times. No significant difference between the trial arms was observed with respect to response of dyspnea. However, a beneficial effect of EBB was noted concerning the mean scores of dyspnea over time ( P =0.02), which lasted for 3 months. This benefit was only observed among patients with an obstructing tumour of the main bronchus. A higher rate of re-expansion of collapsed lung was observed in arm 2 (57%) compared to arm 1 (35%) ( P =0.01). The inspiratory vital capacity (IVC) assessed 2 weeks after radiotherapy improved with 493 cm 3 in arm 2 and decreased 50 cm 3 in arm 1 ( P =0.03). No difference was noted regarding the incidence of massive haemoptysis (13 vs. 15%). Conclusion : The addition of EBB to XRT in NSCLC is safe and provides higher rates of re-expansion of collapsed lung resulting in a transient lower levels of dyspnea. This beneficial effect was only observed among patients with obstructing tumours in the main bronchus.

Detection of Brain Metastases From Small Cell Lung Cancer : Consequences of Changing Imaging Techniques (CT Versus MRI)

The aims of this study were to show 1) the effect of changing from computed tomography (CT) to magnetic resonance imaging (MRI) on the prevalence of detected brain metastases (BM) in patients with newly diagnosed small cell lung cancer (SCLC); 2) the difference in survival between patients with single and multiple BM; and 3) the effect of the change in patient labeling on eligibility for prophylactic brain irradiation.

Response of Asymptomatic Brain Metastases From Small- Cell Lung Cancer to Systemic First-Line Chemotherapy

PURPOSE The purpose of this study was to investigate the radiologic response of asymptomatic brain metastases (BM) from small-cell lung cancer (SCLC) to first-line systemic chemotherapy. PATIENTS AND METHODS From 1990 to 2003, 181 consecutive patients with SCLC were enrolled onto this study. Patients were examined by a neurologist on a regular basis. Magnetic resonance imaging (MRI) of the brain was performed routinely before (at diagnosis of SCLC) and after first-line systemic chemotherapy. Patients were treated with combination chemotherapy consisting of cyclophosphamide, doxorubicin, and etoposide. Clinically manifest BM were treated with whole-brain radiotherapy (WBRT). The response rate (RR) of BM was assessed by changes in the size or the number of enhanced lesions on MRI using standard criteria. RESULTS Synchronous asymptomatic BM were found in 24 SCLC patients (13%). In six (27%) of the 22 assessable patients, the asymptomatic BM responded to systemic chemotherapy. A systemic response was found in 16 patients (73%). All patients became symptomatic during follow-up. The symptom-free survival did not differ between cranial responders and cranial nonresponders. CONCLUSION The RR of asymptomatic BM from SCLC to systemic chemotherapy is 27% and evidently lower than the systemic RR. Future studies should focus on the possible beneficial effect of WBRT for patients with asymptomatic synchronous BM.

MASSIVE HAEMOPTYSIS AFTER RADIOTHERAPY IN INOPERABLE NON-SMALL CELL LUNG CARCINOMA : IS ENDOBRONCHIAL BRACHYTHERAPY REALLY A RISK FACTOR?

BACKGROUND AND PURPOSE This retrospective study was conducted to investigate whether endobronchial brachytherapy (EBB) is a risk factor for massive haemoptysis in patients primarily treated by a combination of EBB and external irradiation (XRT) for NSCLC. MATERIALS AND METHODS The records of 938 patients with inoperable NSCLC who were treated with XRT and/or EBB were reviewed. The patients were divided into five groups as follows: group XRT, treated by XRT alone (n = 421); group XRTelig, treated by XRT but eligible for EBB (n = 419); group XRTEBB, primarily treated with EBB+XRT (n = 62); group EBBrec, treated by EBB for recurrence after XRT (n = 23); and group EBB, treated by EBB alone (n = 13). EBB was delivered using HDR. Patients with bronchoscopy-proven endobronchial tumour in the proximal airways, i.e. the trachea, the main bronchus or lobar bronchus were considered eligible for EBB. RESULTS One hundred one out of 938 patients (10.8%) died from massive haemoptysis. The incidence was 4.3% in group XRT, 13.1% in group XRTelig and 25.4% in group XRTEBB. The differences between groups XRT and XRTelig as well as between groups XRTelig and XRTEBB were statistically significant (P<0.01). The incidence of massive haemoptysis depended significantly on the fraction size of brachytherapy. When two fractions of 7.5 Gy or a single fraction of 10 Gy were used, 11.1% of the patients died from massive haemoptysis. However, when a single dose of 15 Gy was used, 47.8% died from massive haemoptysis. In the multivariate analysis, a single dose of 15 Gy EBB was the most important prognostic factor for massive haemoptysis. CONCLUSION XRT+EBB as primary treatment for NSCLC does not lead to a higher risk of massive haemoptysis as compared to XRT alone when fraction sizes for EBB of 7.5 or 10 Gy are used. However, the risk of massive haemoptysis increases dramatically when a fraction size of 15 Gy is used.

Leptomeningeal metastases from small cell lung carcinoma.

The current study was performed to investigate the frequency of leptomeningeal metastases (LMM) in patients with small cell lung carcinoma (SCLC) as well as the effect of LMM on survival, any correlation between the location of the LMM and survival, and a possible increased risk of LMM among patients with brain metastases (BM) located in the posterior fossa.

Pretreatment Quality of Life of Inoperable Non-Small Cell Lung Cancer Patients Referred for Primary Radiotherapy

This study examined the association between the most important prognostic factors in non-small cell lung carcinoma (NSCLC) and self-reported pretreatment quality of life (QoL) and the impact of the presence, severity and changes in respiratory symptoms on general symptoms and QoL. The study included 262 patients. The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and EORTC QLQ-LC13 were used to assess symptoms and QoL before radiotherapy. Patients with inoperable NSCLC showed major differences in self-reported QoL as a function of clinical prognostic factors. A significant association was found between World Health Organization (WHO) performance status and QoL but not other prognostic factors. Dyspnoea was the only respiratory symptom associated significantly with general symptoms, physical and psychosocial functioning and QoL. Furthermore, changes in dyspnoea were associated significantly with changes in physical and role functioning, global QoL and fatigue as assessed 6 weeks after radiotherapy. These results indicate that palliation of dyspnoea may have a significant beneficial effect on QoL and that palliation of other respiratory symptoms is not necessarily associated with improvement of general symptoms, physical and psychological functioning or global QoL.This study examined the association between the most important prognostic factors in non-small cell lung carcinoma (NSCLC) and self-reported pretreatment quality of life (QoL) and the impact of the presence, severity and changes in respiratory symptoms on general symptoms and QoL.

Quality of life after curative radiotherapy in stage I non-small-cell lung cancer

PURPOSE The aim of this study was to investigate changes in quality of life (QOL) among medically inoperable Stage I non-small-cell lung cancer (NSCLC) patients treated with curative radiotherapy. PATIENTS AND METHODS The study sample was composed of 46 patients irradiated for Stage I NSCLC. Quality of life was assessed before, during, and after radiotherapy using the European Organization for the Research and Treatment of Cancer QLQ-C30 and QLQ-LC13. Changes in symptom and QOL scores over time were evaluated with a repeated measurement analysis of variance using the mixed effect modeling procedure, SAS Proc Mixed. Twenty-seven patients were treated only at the primary site, whereas for 19 patients, the regional lymph nodes were included in the target volume as well. RESULTS The median follow-up time of patients alive was 34 months. The median survival was 19.0 months. None of the locally treated patients developed regional recurrence. A significant, gradual increase over time was observed for dyspnea, fatigue, and appetite loss. A significant, gradual deterioration was observed also for role functioning. No significant changes were noted for the other symptoms or the functioning scales. Significantly higher levels of dysphagia, which persisted up to 12 months, were observed in those in which the regional lymph nodes were treated, as compared to the locally treated patients. Radiation-induced pulmonary changes assessed with chest radiograph were more pronounced in the group treated with locoregional radiotherapy. CONCLUSIONS After curative radiotherapy for Stage I medically inoperable NSCLC, a gradual increase in dyspnea, fatigue, and appetite loss, together with a significant deterioration of role functioning, was observed, possibly because of pre-existing, slowly progressive chronic obstructive pulmonary disease and radiation-induced pulmonary changes. Taking into account the low incidence of regional recurrences after local irradiation, the higher incidence and severity of radiation-induced changes, and the higher levels of dysphagia persisting up to 12 months, local irradiation of the primary tumor without elective irradiation of the regional lymph nodes may be the most appropriate treatment for patients with small, peripherally located tumors.
