Treatment decisions and survival for people with small-cell lung cancer.

BACKGROUND: Chemotherapy improves survival for many patients with SCLC, and hence it is important to understand variations in practice and outcomes for this treatment strategy. METHODS: We used the National Lung Cancer Audit and Hospital Episodes Statistics to determine the proportion of patients who received chemotherapy for SCLC, and assess the effects of patient and organisational factors on the odds of receiving chemotherapy and of completing four cycles. We calculated median survival and used Cox regression to determine factors that predicted survival. RESULTS: Of 15 091 cases of SCLC, 70% received at least one cycle of chemotherapy. More deprived people were less likely to receive chemotherapy, but patients were more likely to receive chemotherapy, and to complete ≥ four cycles, if they were referred to the lung cancer team by their GP. Median survival for those treated with chemotherapy was 12.9 months for limited and 7.3 months for extensive stage disease. CONCLUSIONS: The Linked NLCA and HES data provide real-life measures of survival in people treated with chemotherapy and show how this is influenced by patient and tumour characteristics. These data show the characteristics of patients who are less likely to complete a full course of treatment, an adverse predictor of survival.

Lung cancer survival in England: trends in non-small-cell lung cancer survival over the duration of the National Lung Cancer Audit.

BACKGROUND: In comparison with other European and North American countries, England has poor survival figures for lung cancer. Our aim was to evaluate the changes in survival since the introduction of the National Lung Cancer Audit (NLCA). METHODS: We used data from the NLCA to identify people with non-small-cell lung cancer (NSCLC) and stratified people according to their performance status (PS) and clinical stage. Using Cox regression, we calculated hazard ratios (HRs) for death according to the year of diagnosis from 2004/2005 to 2010; adjusted for patient features including age, sex and co-morbidity. We also assessed whether any changes in survival were explained by the changes in surgical resection rates or histological subtype. RESULTS: In this cohort of 120,745 patients, the overall median survival did not change; but there was a 1% annual improvement in survival over the study period (adjusted HR 0.99, 95% confidence interval (CI) 0.98-0.99). Survival improvement was only seen in patients with good PS and early stage (adjusted HR 0.97, 95% CI 0.95-0.99) and this was partly accounted for by changes in resection rates. CONCLUSION: Survival has only improved for a limited group of people with NSCLC and increasing surgical resection rates appeared to explain some of this improvement.

Stage III Non-small Cell Lung Cancer Management in England.

AIMS: We present the first analysis of the management and outcomes of stage III non-small cell lung cancer (NSCLC) conducted in England using National Lung Cancer Audit data. MATERIALS AND METHODS: Patients diagnosed with stage III NSCLC in 2016 were identified. Linked datasets (including Hospital Episode Statistics, the National Radiotherapy Dataset, the Systemic Anti-Cancer Dataset, pathology reports and death certificate data) were used to categorise the treatment received. Kaplan-Meier survival curves were obtained, with survival defined from the date of diagnosis to the date of death. RESULTS: In total, 6276 cases of stage III NSCLC were analysed: 3827 stage IIIA and 2449 stage IIIB; 1047 (17%) patients were treated with radical radiotherapy with 676 (11%) of these also receiving chemotherapy. Twenty per cent of patients with stage IIIA disease underwent surgery, with half of these also receiving chemotherapy, predominantly delivered in the adjuvant setting. Of note, 2148 (34%) patients received palliative-intent treatment and 2265 (36%) received no active anti-cancer treatment. The 1-year survival was 32.9% (37.4% for stage IIIA), with the highest survival seen for those patients receiving chemotherapy and surgery. CONCLUSIONS: We highlight important gaps in the optimal care of patients with stage III NSCLC in England. Multimodality treatment with either surgery or radical radiotherapy combined with chemotherapy was delivered to less than one-fifth of patients, even though these regimens are considered optimal. Timely access to specialist resources and staff, the practice of effective shared decision making and challenging preconceptions have the potential to optimise management.

Non-small cell lung cancer in young adults: presentation and survival in the English National Lung Cancer Audit.

BACKGROUND: Non-small cell lung cancer (NSCLC) in young adults is a rare but devastating illness with significant socioeconomic implications, and studies of this patient subgroup are limited. AIM: This study employed the National Lung Cancer Audit to compare the clinical features and survival of young adults with NSCLC with the older age groups. DESIGN: A retrospective cohort review using a validated national audit dataset. METHODS: Data were analysed for the period between 1 January 2004 and 31 December 2011. Young adults were defined as between 18 and 39 years, and all others were divided into decade age groups, up to the 80 years and above group. We performed logistic and Cox regression analyses to assess clinical outcomes. RESULTS: Of a total of 1 46 422 patients, 651 (0.5%) were young adults, of whom a higher proportion had adenocarcinoma (48%) than in any other age group. Stage distribution of NSCLC was similar across the age groups and 71% of young patients had stage IIIb/IV. Performance status (PS) was 0-1 for 85%. Young adults were more likely to have surgery and chemotherapy compared with the older age groups and had better overall and post-operative survival. The proportion with adenocarcinoma, better PS and that receiving surgery or chemotherapy diminished progressively with advancing decade age groups. CONCLUSION: In our cohort of young adults with NSCLC, the majority had good PS despite the same late-stage disease as older patients. They were more likely to have treatment and survive longer than older patients.

Treatment patterns and survival analysis in 9014 patients with malignant pleural mesothelioma from Belgium, the Netherlands and England.

INTRODUCTION: Pleural mesothelioma has a dismal prognosis and is refractory to local treatment. Combination chemotherapy can increase median survival by several months and was gradually introduced in the period 2003-2006. Elderly patients may be unfit for chemotherapy but little is known about age-related treatment practice. To determine treatment patterns and current survival outcome, three large population-based registries were queried in a uniform manner. METHODS: Data from the Belgian Cancer Registry, the Netherlands Cancer Registry and the UK National Lung Cancer Audit were analyzed for patients diagnosed with pleural mesothelioma since 2007. Treatment patterns and survival rates were compared between countries and age-groups. RESULTS: The study included 900, 2306 and 5808 patients from Belgium, the Netherlands and England, respectively. Fifty-nine percent of patients were 70 years or older and 84% were men. Chemotherapy use decreased with advancing age and was used more often in Belgium (60%) than in the Netherlands (41%) and England (37%). For patients aged 70-79 years, chemotherapy use was 55%, 36% and 34% in the respective countries. Median survival was 10.7 months in Belgium versus 9.2 months for the Netherlands and 9.5 months for England. Survival rates decreased with advancing age. On average, median survival was 5.6 months longer for patients treated with chemotherapy, irrespective of age. CONCLUSIONS: Combined analysis of data from three countries with high mesothelioma rates demonstrates that chemotherapy has become standard treatment for younger patients. Elderly patients currently account for more than half of all cases and less toxic treatment options will be required to improve their prospects.
