Unrealistic expectations and disclosure of incurability in patients with non-small cell lung cancer.

Abstract

Determining whether patients' unrealistic expectations of chemotherapy as a cure were associated with their perception of the disclosure of incurability. This prospective study included consecutive patients with pretreated non-small cell lung cancer from four study sites. Patients and their oncologists were asked whether they perceived the disclosure of cancer incurability. Patients were also asked if they thought that chemotherapy was curative. We followed up on whether the deceased patients received specialized palliative care 14 months after their last enrollment. Multiple regression analyses were conducted to examine the association between the expectation of chemotherapy as a cure and patient/oncologist-reported perceptions of the disclosure of incurability. We analyzed 200 patients, 77 (38.5%) of whom had unrealistic expectations of a cure. Based on patients' perceptions, incurability was disclosed to 138 (69.0%) patients, and based on their oncologists' perceptions, incurability was disclosed to 185 (92.5%) patients (patient/oncologist agreements, κ = 0.19). Patients without a perception of the oncologist's disclosure of incurability-regardless of their oncologist's perception-were more likely to have unrealistic expectations of a cure than patients for whom both patient and oncologist perceptions were present. Patients who had unrealistic expectations of chemotherapy as a cure were shown to be significantly less likely to have received specialized palliative care, after adjusting for covariates (adjusted OR, 0.45; 95% CI, 0.23-0.91; p = .027). Oncologists' disclosure of incurability was not fully recognized by patients, and expectations of chemotherapy as a cure were associated with patients' perception of the disclosure of incurability.
