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

March 3, 2026 updated by: University Health Network, Toronto

Prospective Observational Study Of Patients With Asymptomatic Centrally Located Advanced NSCLC Who Are Not Suitable For Curative Treatment

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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Study Population

Patients with Centrally Located Advanced NSCLC who are Asymptomatic and who are not Suitable for Curative Treatment

Description

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

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
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
Time Frame: 6 years
6 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
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
Time Frame: 6 years
6 years
To explore the relationship between utility and initial treatment decision (immediate versus deferred)
Time Frame: 6 years
6 years
To describe the disease status (as per CT imaging) at 4 months
Time Frame: 6 years
6 years
To describe the overall survival in patients with ACLA-NSCLC
Time Frame: 6 years
6 years

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
November 1, 2010

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
