Purpose: To investigate if timing of first visit, ages, sex, family history of cancer, and smoking history would cause any differences in patients' attitude toward cancer disclosure.
Subjects and methods: Subjects were 10,552 patients who first visited Urology Department of Nihonkai Hospital between 1993 and 2007, and were asked to fill in the questionnaire. The questionnaire contents are as follows: "If you were diagnosed as having cancer, would you like to be informed about the diagnosis of your disease?", and "If your families were diagnosed as having cancer, would you like to inform them about the diagnosis of their disease?". The subjects were asked to select their answers from the following options: (1) "fully informed", (2) "informed only when it is curable", (3) "not informed", and (4) "can not decide now". The relation of patients' attitude toward cancer disclosure with the timing of first visit, ages, sex, family history of cancer, and smoking history was investigated.
Results: The response rate was approximately 80%. If the subjects would have cancer, 71.5% preferred to be informed ("fully informed" or "informed if it is curable"), and 9.2% did not. If the subjects' family would have cancer, 55.5% preferred their family to be informed ("fully informed" or "informed if it is curable"), and 14.9% did not. As it became more recent, both the rate of subjects who did not prefer to be informed (11.5% in 1993-1995, and 8.0% in 2005-2007) and the rate of those who did not prefer their family to be informed (18.6% in 1993-1995, and 11.0% in 2005-2007) decreased. Young subjects, men, and smokers more preferred to be informed. The subjects who had family history of cancer more preferred to inform them, but less to inform their family.
Conclusions: As it became more recent, both the subjects who did not prefer to be informed and those who did not prefer their family to be informed decreased. The idea that cancer disclosure was necessary to select the treatment methods based on each patient's preference and decision had been pervasive.
