Observing Patients With Palliative Asymptomatic Centrally Located Advanced Non-small Cell Lung Carcinoma (NSCLC)

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to assess current practice within PROP & lung teams, for treating asymptomatic patients with centrally located non-small cell lung cancer (NSCLC), and to observe outcomes for those patients receiving immediate or deferred RT. This is a prospective cohort trial. Patients will be managed by immediate radiotherapy (RT) or a deferred approach according to physicians' individual current clinical practice. Baseline and follow-up data collection will be structured to focus on patient-reported measures to describe clinical outcomes in the two management groups. Indications for prescribing RT and dose fractionation schedules will also be collected. A new intervention will not be introduced during this trial. Instead, a follow-up regimen will be offered to both groups of patients, so that RT can be offered to the deferred group of patients if/when symptoms develop, and we can monitor symptoms/toxicities and QoL in both groups of patients.

Eligibility Criteria
-----------------
Inclusion Criteria: Histologically or cytologically confirmed NSCLC Central disease, as defined by tumour (either primary or nodal disease) arising or extending within a 2cm circumferential expansion from the centre of the trachea or within the zone of the proximal bronchial tree Disease is visible on thoracic CT (diagnostic or simulation) Asymptomatic from intra-thoracic tumour (may have background chest symptoms related to underlying COAD etc, but these symptoms must not have worsened due to tumour) Patient (due to age or co-morbidities) or tumour (due to locally advanced or metastatic disease) is not suitable for radical treatment (defined as surgery or RT dose >50Gy in 20 fractions or equivalent). Previous chemotherapy, thoracic RT or surgery is allowed RT to other metastases (e.g. brain, bone etc) is allowed •≥ 18 years of age Able to provide written informed consent Exclusion Criteria: Intra-thoracic disease is peripheral only, not extending within 2cm of trachea/proximal bronchial tree Symptomatic from intra-thoracic NSCLC Histological diagnosis of small cell lung cancer, or malignant mediastinal lymphadenopathy from another malignancy (not NSCLC)

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To determine the pattern of practice for management (immediate radiotherapy, deferred radiotherapy) of patients with ACLA-NSCLC, including reasons, timing and dose fractionation of lung/mediastinal RT |  | 6 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To describe the patient reported outcomes (symptoms, toxicities and quality of life measures) in patients with ACLA-NSCLC at 4 and 12 months |  | 6 years | 
| To explore the relationship between utility and initial treatment decision (immediate versus deferred) |  | 6 years | 
| To describe the disease status (as per CT imaging) at 4 months |  | 6 years | 
| To describe the overall survival in patients with ACLA-NSCLC |  | 6 years |
