Clinicians are often reluctant to request an autopsy for patients who
have been extensively investigated during life, because they may belie
ve that little additional information will be obtained. To examine whe
ther this is the case, the autopsy records of pediatric oncology patie
nts at the Adelaide Children's Hospital were reviewed. A total of 63 o
ncology patients died in the hospital during the period 1982-1991, 28
of wham underwent postmortem examination. Class I findings (those that
would have altered management if they had been known during life) wer
e found in 7 cases (25 %). Major pathological findings that would not
have altered management (class II) were found in 14.3 % of cases. The
most common class I findings were fungal infections with organisms suc
h as Aspergillus or Candida species. Postmortem examination also revea
led treatment-related complications in five patients, and in one case
the diagnosis was made only at autopsy. This study confirms that postm
ortem examination can provide valuable new information even for patien
ts who had been widely investigated in life and in whom the cause of d
eath may appear obvious.
