Attitudes to chemotherapy in patients with ovarian cancer

Recurrent ovarian cancer (OVCA) has become the model for cancer as a chronic disease, yet little is known about what motivates patients and physicians in treatment choices.

We investigated the attitudes of patients with epithelial OVCA and staff towards palliative chemotherapy for recurrent OVCA with a cross-sectional questionnaire study.

Instruments were developed and piloted in 15 patients. This exploratory study reflects substantial bias in the sample populations. One hundred twenty-two patients and 37 staff were enrolled in the US and 39 patients and 25 staff were enrolled in the UK. UK patients had a lower educational status (P = 0.001), lower stage disease (P = 0.025), and less prior lines of chemotherapy (P < 0.001). 61% of patients had recurrent OVCA and 67% of staff were physicians. Seventy-three percent of patients recalled a discussion about prognosis and 74% wanted to know details of the prognosis for a typical patient (US = UK). Most patients (48%) thought that their physician was realistic, and 57% of staff felt that they were optimistic. The vast majority of both staff and patients thought that patients positively reinterpreted what they were told. Five percent of staff thought that palliative care was "incompatible" when considering chemotherapy as an option for their second recurrence of OVCA, compared with 36% of US patients, significantly more than the 12% of UK patients (P = 0.007). Patients thought that standard chemotherapy for a second recurrence of OVCA produced remission in 50% and cure in 15% of patients. Staff reported 20% and 0%, respectively. Fifty percent of patients and 57% of staff would want chemotherapy as an asymptomatic patient with a normal CT and a rising CA-125. Patients generally appear to be very tolerant of grade II chemotherapy-induced toxicity with staff being less tolerant than patients of nausea, anorexia, diarrhea, and rash. Staff rated life prolongation by 3 months to 1 year very much less acceptable than patients (P < 0.001). Although possibly allowing comprehensive collection of sensitive data, the questionnaire was too distressing for some patients and made 11% of patients feel uncomfortably anxious.

Patients are optimistic and in the US, may be more reluctant than staff to see the Palliative Care Team. These data challenge the assertion that the use of palliative chemotherapy is physician-driven.
