(A): Physicians’ reports of disclosure of information to advanced lung cancer patients and caregivers. (B–E): Illness understanding in advanced lung cancer patients and their caregivers associated with physicians’ explanations. Proportions of participants with accurate understanding are shown in bar graphs. Perceptions of prognosis in 183 patients (B) and in 164 caregivers (C). Physicians’ explanations to caregivers about future discontinuation of anticancer treatment were correlated at a statistically significant level with caregivers’ accurate perceptions of prognosis (*; Fisher's exact test for comparison, p = .021). Perceptions of goals of therapy in 182 patients (D) and in 163 caregivers (E). There was no significant difference in physicians’ explanations concerning perceptions of goals of therapy for both patients and caregivers.
