Perspectives of patients and physicians about neuroendocrine tumors. A qualitative study

Gastrointestinal neuroendocrine tumors (NETs) are rare, complex to manage, and often have a chronic course. Qualitative methods are a tool of choice for focusing on patients' and physicians' points of view especially when dealing with a complex and rare disease. Nonetheless, they remain undeveloped in research related to NETs. This study aimed to explore the experience of NETs among both patients and their physicians and to cross their perspectives for the purpose of finding pathways to improving care.

Our analysis found two themes: (1) the questions raised by this disease, and (2) the complex experience of this singular disease. Our findings underlined the experience of confusion found among patients regarding the patient's unusual somatic experience and around the question of vocabulary, i.e. the naming of the disease and the semantic field of severity in the medical discourse.

Means for reducing the confusion that patients experience in this disease are needed. The explanations that the physician offers to the patient must clarify the issues related to NETs. We therefore propose a statement that all physicians can use to support patients diagnosed with neuroendocrine tumors to clear up potential confusion.

We conducted a qualitative study, based on 40 semi-structured interviews, in a specialized department of gastro-pancreatology. Participants, purposively selected until data saturation, came from two different sub-samples: (i) patients with a metastatic NETs (N = 20) and (ii) their referring physicians (N = 10). The data were examined by thematic analysis.
