The tube is inserted through the patient’s nose or mouth. Bronchoscopy may be used to find cancer or as part of some treatments to deliver therapeutic agents Chronic obstructive pulmonary disease A lung disease characterised by chronic obstruction of lung airflow (COPD) that interferes with normal breathing and is not fully reversible Clinical trial A research study in which patients volunteer to test new ways of screening, preventing, diagnosing, or treating a disease Clinical network Process for planning, coordination, delivery and evaluation of care in a defined clinical setting or geographical location Co-morbidity Two or more health problems at the same time Consultations Round 1 The first survey distributed via a secure online platform to identify experts’ opinions on the causes of variations in lung cancer care in Australia. Consultation Round 2 The second survey distributed via a secure online platform to identify guideline content and strategies to decrease variations in lung cancer care Computerised tomography (CT) scan A technique for constructing pictures from cross-sections of the body, by x-raying the body from many different angles Cultural competency Cultural competence in health care describes the ability of systems to provide care to patients with diverse values, beliefs and behaviours, including tailoring delivery to meet patients’ social, cultural, and linguistic needs Disability-adjusted life years (DALY) A measure used in burden of disease and injury estimates, which combines the years of life lost due to premature death (YLL) and the equivalent ‘healthy’ years of life lost due to disability or illness (YLD). One DALY represents one lost year of ‘healthy’ life. Endobronchial ultrasound (EBUS) An invasive procedure in which physicians use ultrasound devices inside the airways and the lung for exploration of the structures of airway walls, the surrounding mediastinum, and the lungs Expert Consultations Interviews that were conducted with experts in cancer care and consumers Expert Participants (EPs) Those that participated in the Expert Consultations Literature review and national consultation on factors impacting on lung cancer outcomes | vii Gender Refers to the socially constructed roles, behaviour, activities and attributes that a particular society considers appropriate for men and women. The distinct roles and behaviour may give rise to gender inequalities Health Literacy The knowledge and skills required to understand and use information relating to health issues. Local Government Area A term used in Australia (particularly by the Australian Bureau of Statistics) to refer to areas controlled by each individual Local Government Mesothelioma Pleural mesothelioma is a cancer of the membranes of the lung. The commonest cause of mesothelioma is exposure to asbestos. This project does not cover mesothelioma Magnetic Resonance Imaging (MRI) A type of body scan that uses a magnet linked to a computer to make detailed pictures of areas inside the body. An MRI can be used to find cancer Non-small cell lung cancer One of the two main groups of lung cancers. This group includes squamous cell carcinoma, adenocarcinoma, large cell carcinoma and bronchiolo-alveolar cell carcinoma Oncologist A doctor who specialises in studying and treating cancer Positron Emission Tomography (PET) In a PET scan, the patient is given radioactive glucose (sugar) scan through a vein. A scanner then tracks the glucose in the body. The scanner’s pictures can be used to find cancer, since cancer cells tend to use more sugar than other cells Primary cancer The first or original cancer Prognosis The expected course of a disease and the chances of recovery Qualitative Thematic Analysis Thematic analysis is a method for identifying, analysing and reporting patterns within qualitative material. This process allows clear identification of prominent themes, and provides an organised and structured way of dealing with the narrative data. Radiation The emission of energy in waves or particles. Often used to treat cancer cells Radiation oncologist A doctor with specialist training in treating cancer patients using radiation Risk Assessment Determination of quantitative or qualitative risk related to a situation or a recognised threat Screening Checking for disease or precursors of a disease when there are no symptoms. Since screening may find diseases at an early stage, there may be a better chance of curing the disease viii | Report on lung cancer in Australia Small cell lung cancer A type of lung cancer made up of small, round cells.
