Oral sources of septicaemia in patients with malignancies.

This article reviews papers dealing with oral infections of adult septicaemia patients, searched from MEDLINE, Current Contents and Core Biomedical Collection databases from January 1966 to November 1996. Case reports were excluded. The systematic review of literature revealed that our knowledge of the topic is mostly based on very small patient material. There are no multicentre studies on the effects of various oral health treatment modes on the prevention of septicaemia of oral origin. The number of controlled and comparative studies on the efficacy of the different treatment protocols of oral infections is also small. Current recommendations in this respect are mainly empirical and not evidence based. Clinical practice guidelines are therefore urgently needed. Nevertheless, close co-operation between oncological and oral health units is emphasised because many studies have shown that the oral cavity is indeed an important source of bacteraemia. Life-threatening infections may follow if maintenance of oral health is neglected during anticancer therapy and if potential oral infection foci are left untreated before immunosuppressive therapy.
