Experience of individuals with lung and gastrointestinal cancers undergoing radiation therapy: a qualitative study

Purpose: Lung cancer remains one of the most diagnosed cancers in Canada and continues to be the leading cause of cancer deaths in Canada, responsible for 25% of all cancer deaths. Prior studies consistently report poor experiences of people with lung cancers. The study purpose was to explore the reasons for consistently poorer reported experience of people with lung cancer compared to people with gastrointestinal cancers, who previously have reported positive cancer care experiences within the same context, and to better understand key differences that influence patient experience.

Methods: This qualitative study used semi-structured interviews of people living with lung cancer (LC) and gastrointestinal cancers (GIC) undergoing radiotherapy at a tertiary cancer centre. Thematic content analysis was conducted to analyse interview transcripts. A person-centred care framework was used to guide the development of the interview guide and data analysis.

Results: We interviewed 16 participants (10 LC and 6 GIC). Participants with LC reported poor experience leading to and at the time of their cancer diagnosis, including delays in their diagnosis and anxiety related to their diagnosis. Most participants in both groups reported severe symptoms prior to their radiotherapy. However, the symptoms of people living with LC further worsened during the radiation therapy with the addition of treatment side effects, while the symptoms of people living with GIC were better controlled during treatment. Participants living with LC noted poor communication, gaps in coordination and uncertainty. They acknowledged awareness of support services and other resources, but they reported no interest in accessing them.

Conclusion: This study identified gaps in patient experience of people living with LC compared to GIC and proposed ideas for quality improvement projects, including expediting the diagnosis process, enhancing communication with patients around their lung cancer diagnosis, improved symptom management, and timing of supportive care services.
