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

ABSTRACT: 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.

Project description:INTRODUCTION:Advanced non-small cell lung cancer (NSCLC) is a severe disease with burdensome symptoms and traditionally poor outcomes. The treatment of advance disease is based on chemotherapy, with the recent addition of immunotherapy. Patients who respond to initial treatment can opt to receive maintenance therapy (MT). It is important to understand why patients with advanced NSCLC choose to accept or refuse therapy, and how physician recommendations play into this decision-making process. This study characterized patient and physician decision-making regarding treatment for patients with advanced non-squamous NSCLC in the USA using the example of MT. METHODS AND MATERIALS:This study employed multiple approaches: patient interviews, a patient survey, and a physician survey. Qualitative interviews were conducted among patients who had been offered MT to identify factors influencing treatment decision-making. The patient survey explored the decision-making process and quantified challenges and motivators for receiving MT. The physician survey included a discrete choice experiment to understand the relationship between physician treatment recommendations and patient characteristics. RESULTS:Interviewed patients (n?=?10) were motivated to receive MT in the hope of extending their lives and being proactive against their cancer, and they anticipated reduced adverse effects compared with first-line therapy. Surveyed patients (n?=?77) described several deterrents to receiving therapy; the most prominent was severity of adverse effects, which was an influencing factor for 34% of patients. The major motivator for receiving therapy was the potential to extend life, which influenced 97% of patients. A total of 100 oncologists participated in the physician survey. Patients' lack of treatment motivation/inconvenience, disease progression, presence of severe renal co-morbidities, and older age decreased the likelihood of physicians recommending the use of MT. CONCLUSION:This study identified challenges and motivators influencing advanced NSCLC patients' decisions to accept or refuse therapy, as well as patient and disease characteristics associated with physician's treatment recommendations for MT.

Project description:BackgroundTo eliminate them, non-small cell lung cancer (NSCLC) care and outcome disparities need to be better understood.Research questionHow does rurality interact with NSCLC care and outcome disparities?Study design and methodsWe examined guideline-concordant use of active treatment for NSCLC across five institutions in one community-based health care system spanning 44% of the Delta Regional Authority catchment area from 2011 to 2017. Institution- and patient-level rurality were based on Rural-Urban Commuting Area codes. Chi-squared, F-tests, and logistic regressions were used to analyze differences across institutions and rurality; survival was examined using log-rank tests and Cox regression.ResultsOf 6,259 patients, 47% resided in rural areas; two of five institutions were rurally located and provided care for 20% of patients. Compared with rural residents at rural institutions, urban and rural residents attending urban institutions were more likely to receive stage-preferred treatment: OR 1.68 (95%CI, 1.44-1.96), and 1.33 (1.11-1.61), respectively, after adjusting for insurance, age, and clinical stage. Urban and rural residents attending urban institutions had a lower hazard of death compared with rural residents attending rural institutions: hazard ratio (HR) 0.69 (0.64-0.75) and 0.61 (0.55-0.67), respectively. Among recipients of stage-preferred treatment, care at urban institutions remained less hazardous: HR 0.7 (0.63-0.79). When further stratified by stage, care for late-stage patients at urban institutions remained less hazardous: HR 0.8 (0.71-0.91).InterpretationRurality-associated treatment and survival disparities were present at the patient and institution levels, but the institution-level disparity was greater. Rural residents receiving care at urban institutions had similar outcomes to urban residents receiving care at urban hospitals. To overcome rurality-associated NSCLC survival disparity, interventions should preferentially target the institution level, including expanding access to higher-quality guideline-concordant care.
