Patients with advanced cancer experience various kind of suffering such as physical pain, psychological suffering, or existential suffering. Art therapy is one of the most effective psychological cares. The aim of this study was to investigate the psychological utility of art therapy for patients with advanced cancer. Eight patients with advanced cancer received art therapy with an art therapist from two to four times in a general hospital. They made art including drawing pictures or making collages to express their feelings and thoughts. Each patient explained his art after each session and discussed changes that they had undergone between sessions. The therapist wrote down patients' words including explanation toward arts, their emotions, and thoughts, then categorized to evaluate the utility of the art therapy, and the following categories emerged: "Promotion of communication with other patients," "Promotion of communication with family members," "Hope for the future," "Making psychological space to forget illness," "Missing the good old times," and "Relaxation." These results suggest that art therapy has psychological utility for patients with advanced cancer such as promoting communication, finding hopes for the future, and adapting to life in the hospital.
