Uncovering the realities of suicidal ideation in older patients following lung cancer diagnosis: an interpretive phenomenological qualitative study

Support Care Cancer. 2026 May 25;34(6):575. doi: 10.1007/s00520-026-10810-y.

ABSTRACT

BACKGROUND: Lung cancer predominantly affects older adults, and the median age at diagnosis is about 71 years. It carries the highest suicide burden among all malignancies, with roughly a 4.2 times increase in suicide mortality compared with the general population. Qualitative evidence on how these patients experience suicidal thoughts after diagnosis is scarce.

OBJECTIVES: This study aimed to uncover the realities and lived experiences of suicidal ideation in older patients following a lung cancer diagnosis, thereby providing insights for targeted psychosocial support.

STUDY DESIGN: An interpretive phenomenological qualitative study.

METHODS: Eleven participants were recruited through convenience sampling at a tertiary hospital in China. Data were collected via semi-structured interviews, with each session lasting 20 to 40 min. Transcripts were analyzed using interpretive phenomenological analysis to identify recurring themes and subthemes.

RESULTS: Two predominant themes were identified: (1) intrapersonal dynamics of suffering and (2) interpersonal and existential dilemmas. Findings revealed that older patients experienced intense emotional distress and debilitating physical pain, which often led to feelings of being “imprisoned” by their condition. Social isolation and a perceived lack of deep emotional understanding from support networks significantly fueled a sense of despair and loss of control. However, many participants eventually navigated a transformative “meaning-making” process, redefining hope through small daily joys and a renewed focus on meaningful life reflections.

CONCLUSIONS: The elevated risk of suicide in older patients with lung cancer is a critical clinical concern requiring urgent attention. Targeted suicide prevention interventions must be implemented to address the complex interplay of physical, psychological, and social challenges. Such holistic support is essential for enhancing psychological resilience and the overall quality of life for this vulnerable population.
