[Semantic analysis of online conversations on lung cancer: The WE-Lung research]

Abstract

Introduction: Today, patients with lung cancer and their relatives can easily search information on the Internet and express themselves online.

Methods: Within this web-ethnographic research, we found, based on 246 search terms related to lung cancer, and collected, a sample of 136 online conversations that were published between January 2004 and September 2018, including 1220 messages by 762 authors.

Results: The authors of messages, many of them close relatives of patients (35%), share their experience (34%). Seven areas of worrying concern, each of them prominent in 10 to 24% of the corpus, can be grouped under three headings: accepting the disease in order for the patient or their caregiver to fight it ("decide on the prognosis", "managing the treatments", "stopping the progression"), conjuring fate ("naming the guilty ones", "conjuring powerlessness"), asserting resilience ("adopt the right attitude" and "telling one's story in order to survive"). The question of time - disrupted, lost, to be caught up with or controlled - runs through all the issues.

Discussion: The patients' and caregivers' concerns go beyond the pace of medical treatment and beyond death. Their mental representations of the disease influence their adherence to the care pathway. Welcoming them in our care and dialogue goes hand in hand with personalized treatment.
