Purpose: Develop a method for extracting smoking status and quantitative smoking history from clinician notes to facilitate cohort identification for low-dose computed tomography (LDCT) scanning for early detection of lung cancer.

Materials And Methods: A sample of 4,615 adult patients were randomly selected from the Multiparameter Intelligent Monitoring in Critical Care (MIMIC-III) database. The structured data were obtained by queries of the diagnosis tables using the International Classification of Diseases codes in use at that time.

Purpose: Lung cancer screening with low-dose CT (LDCT) demonstrated reduced mortality in the National Lung Screening Trial, yet there is debate as to whether the reported efficacy can translate into comparable effectiveness with community-based screening. The authors' purpose is to report the baseline patient characteristics and malignancy rate in the first 18 months after implementing a lung cancer screening program in an integrated community health system.

Methods: Patients were screened at 1 of 10 participating community-based centers within a 22-hospital system from 2013 to 2015.

Background: Advanced imaging and serum biomarkers are commonly used for surveillance in patients with early-stage breast cancer, despite recommendations against this practice. Incentives to perform such low-value testing may be less prominent in integrated health care delivery systems. The purpose of the current study was to evaluate and compare the use of these services within 2 integrated systems: Kaiser Permanente (KP) and Intermountain Healthcare (IH).

Purpose: Advanced imaging is commonly used for staging of early-stage breast cancer, despite recommendations against this practice. The objective of this study was to evaluate and compare use of imaging for staging of breast cancer in two integrated health care systems, Kaiser Permanente (KP) and Intermountain Healthcare (IH). We also sought to distinguish whether imaging was routine or used for diagnostic purposes.

With increasing numbers of communities harmed by exposures to toxic substances, greater understanding of the psychosocial consequences of these technological disasters is needed. One community living the consequences of a slow-motion technological disaster is Libby, Montana, where, for nearly 70 years, amphibole asbestos-contaminated vermiculite was mined and processed. Former mine employees and Libby area residents continue to cope with the health consequences of occupational and environmental asbestos exposure and with the psychosocial challenges accompanying chronic and often fatal asbestos-related diseases (ARD).

Background: Pemetrexed has emerged as one of the most active agents for the treatment of patients with advanced non-small cell lung cancer (NSCLC). We conducted a phase II study to assess the efficacy and feasibility of integrating pemetrexed in a concurrent therapy plan for patients with stage III NSCLC.

Methods: Patients with stage III NSCLC with performance status 0 to 1, adequate organ function including pulmonary function, and V20 less than 40% were eligible.

In recent years, there have been significant advances in the management of patients with lung cancer. This progress is associated with increased use of medical intensive care units (ICUs) for the management of a variety of complications related to cancer, its treatment, or comorbid illnesses. At the same time, there are advances in the care of critically ill patients in general.

Social support is an important resource for communities experiencing disasters. However, a disaster's nature (rapid- versus slow-onset, natural versus technological) may influence community-level responses. Disaster research on social support focuses primarily on rapid-onset natural disasters and, to a lesser extent, rapid-onset technological disasters.

Introduction: Thoracic malignancies and human breast cancer (HBC) continue to be aggressive solid tumors that are poor responders to the existing conventional standard chemotherapeutic approaches. Malignant pleural mesothelioma (MPM) is an asbestos-related tumor of the thoracic pleura that lacks effective treatment options. Altered ubiquitin proteasome pathway is frequently encountered in many malignancies including HBC and MPM and thus serves as an important target for therapeutic intervention strategies.

Much cancer-related health communication research has involved studies of the effects of media campaigns and strategies on secondary prevention. Cancer diagnosis rates, however, continue to affect millions of people. The need exists for communication studies to address the quality of the clinical interaction, the point of actual care delivery in addressing diagnosis, treatment, and survivorship.

Introduction: The link between lung cancer and chronic obstructive lung diseases (COPD) has not been well studied in women even though lung cancer and COPD account for significant and growing morbidity and mortality among women.

Methods: We evaluated the relationship between COPD and non-small cell lung cancer in a population-based case-control study of women and constructed a time course of chronic lung diseases in relation to onset of lung cancer. Five hundred sixty-two women aged 18 to 74, diagnosed with non-small cell lung cancer and 564 population-based controls matched on race and age participated.

Objective: To test whether cancer patients' expectations for cure prior to interacting with their oncologist influence their decisions to follow treatment recommendations. Further, to test whether patients' expectations for cure are affected by the strength of the oncologist-patient alliance or the extent to which companions (if present) share patients' expectations for cure.

Methods: Interactions of 101 patients (and 114 companions) with oncologists about treatment were coded for the strength of the oncologist-patient alliance.

Introduction: The utility of two-drug chemotherapy regimens in elderly or performance status (PS 2) patients with advanced non-small cell lung cancer (NSCLC) remains to be established. Preclinical studies suggested that celecoxib, a Cyclooxygenase-2 inhibitor, has antitumor activity in NSCLC and can enhance the activity of chemotherapy drugs. We conducted a phase II study to evaluate the efficacy of the combination of weekly docetaxel and celecoxib in advanced NSCLC patients, who were either elderly (> or =70 years) or PS2.

Purpose: To investigate how communication among physicians, patients, and family/companions influences patients' decision making about participation in clinical trials.

Patients And Methods: We video recorded 235 outpatient interactions occurring among oncologists, patients, and family/companions (if present) at two comprehensive cancer centers. We combined interaction analysis of the real-time video-recorded observations (collected at Time 1) with patient self-reports (Time 2) to determine how communication about trial offers influenced accrual decisions.

We investigated the relationship between parents' empathic responses prior to their children undergoing cancer treatment procedures and children's pain/distress during the procedures. We hypothesized: (1) parents' empathic distress would be positively associated with children's pain/distress, (2) parents' empathic concern would be negatively associated with children's pain/distress; and (3) parents' enduring dispositions and social support would be associated with their empathic responses. Parents completed: (1) measures of dispositions and perceived social support several weeks before their children underwent the procedures, and (2) state measures of empathic distress and empathic concern just before the procedures.

Study Objectives: Stage IIIA non-small cell lung cancer represents a relatively heterogeneous group of patients with metastatic disease to the ipsilateral mediastinal (N2) lymph nodes and also includes T3N1 patients. Presentations of disease range from apparently resectable tumors with occult microscopic nodal metastases to unresectable, bulky multistation nodal disease. This review explores the published clinical trials to make treatment recommendations in this controversial subset of lung cancer.

Background: Gefitinib, an epidermal growth factor receptor tyrosine kinase inhibitor, has demonstrated a response rate of 9%-18% in relapsed non-small cell lung cancer (NSCLC) patients. The probability of response to gefitinib was not influenced by response to previous chemotherapy. Preclinical studies have suggested that celecoxib, a cyclooxygenase-2 inhibitor, has antitumor activity in NSCLC and can enhance the activity of EGFR inhibitors.

Previous research has investigated patient question asking in clinical settings as a strategy of information seeking and as an indicator of the level of active patient participation in the interaction. This study investigates questions asked by patients and their companions during stressful encounters in the oncology setting in the USA. We transcribed all questions patients and companions asked the oncologist during 28 outpatient interactions in which "bad news" was discussed (n = 705) and analyzed them for frequency and topic.
