Parenteral oestrogen: Effective and safer than both oral oestrogen and contemporary androgen deprivation therapy for prostate cancer?

摘要

We also think that hospital mortality as primary outcome bears a potential pitfall in our setting, because we are a large tertiary referral university hospital. A discharge of patients from our normal ward in the university hospital to a normal ward of a smaller hospital nearby is a common scenario. A referred patient would be excluded from the database and appear as survivor, yet he/she is still in hospital care. Obviously this does not mean that a discharged/referred patient should not be admitted to a hospital. Considering the definite hospital mortality as our primary endpoint is therefore misleading.
