How past alcohol or drug use affects detection and treatment of non-small cell lung cancer

Qualitative Study on Detection and Treatment of Non-Small Cell Lung Cancer in Patients With a History of Alcohol or Substance Use Disorder

Observational University of Southern California · NCT07186699

This project will talk with adults who have non-small cell lung cancer and a history of alcohol or drug use to see if those histories help or hinder getting detected and treated.

What this trial studies

This observational qualitative project will conduct semi-structured interviews (30–60 minutes) with adults diagnosed with non-small cell lung cancer who had alcohol or other substance use disorders in the prior 10 years, with optional follow-up focus groups to review preliminary findings. Participants will be recruited at Keck/USC, Los Angeles General Medical Center, and Norris Comprehensive Cancer Center and interviews will be conducted in English or Spanish. The aim is to identify social facilitators and barriers that affect timely detection and receipt of curative-intent treatment. Results will be used to inform outreach, care coordination, and possible interventions to improve access and outcomes for this population.

Who should consider this trial

Good fit: Adults (18+) with histologically confirmed non-small cell lung cancer who have received or are receiving curative-intent treatment and who had alcohol use or another substance use disorder within the past 10 years, and who speak English or Spanish, are ideal candidates.

Not a fit: Patients without a history of alcohol or non-tobacco substance use, those unable to maintain a 30–60 minute conversation due to cognitive impairment, and non-English/Spanish speakers are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could guide changes in outreach, screening, and care coordination to improve timely detection and treatment for patients with histories of alcohol or substance use.

How similar studies have performed: Qualitative studies have previously identified social and structural barriers to cancer care, but focused research specifically on patients with alcohol or substance use histories in NSCLC is limited.

Eligibility criteria
