The value of necropsy in oncology.

ABSTRACT

The effectiveness of diagnostic procedures in cancer patients was evaluated by comparing clinical with necropsy findings. Necropsy and clinical records of 102 patients were reviewed for primary site and histology of tumour, metastatic sites, presence of second neoplasms, associated non-neoplastic diseases, terminal illness and cause of death. Major discordances between clinical and postmortem findings were found in 34 (33%) cases in 10 of these a correct clinical definition of site and histology of the primary tumour would have resulted in a change of management and prognosis; in 4 cases in which a major non-neoplastic pathology had been responsible for death, correct diagnosis might have resulted in prolongation of survival. Spread of disease was generally underestimated, even for metastases in clinically accessible organs. Even more disappointing were the clinical data related to terminal illness and cause of death (43% overall concordance).
