The disclosure of information to cancer patients is one of the most importa
nt issues in oncological practice. In Japan, as in some of her countries,fe
w cancer patients were ever given a truthful statement of their diagnosis.
However, today more and more patients are being informed of their diagnosis
and prognosis. This study investigates the nature of these changes in disc
losure policy and suggests possible explanations. We reviewed the medical a
nd nursing charts of 122 adult cancer patients admitted to our hospital in
1993 and 137 admitted in 1998. We examined the information they had been gi
ven, and their sociodemographic and medical characteristics. The diagnosis
of cancer was shaved with 27% of patients in 1993. In 1998, however, 71% we
re informed of their cancer, and 10% were also told they had a poor prognos
is. The rate of disclosure was lower for older patients and those with adva
nced cancer in both 1993 and 1998. In 1998 the rate was higher in patients
undergoing chemotherapy and/or surgery. The higher level of disclosure in 1
998 was due basically to the growing importance of informed consent. Psychi
atric referrals increased from 2% in 1993 to 10% in 1998. Psychiatrists may
have contributed to these changes in the disclosure of information. (C) 20
