title: Malignant tumors at very old ages.
abstract: Unselected autopsy findings of nonagerians reviewed by the authors in the last 20 years, confirm a decline in malignant tumors at very old ages. Two main factors are thought to be responsible for this evidence: a less aggressive biological behavior of cancer in the oldest old; the crucial role played by comorbidity as the cause of death.
