| pubmed-article:692903 | pubmed:abstractText | The importance of exfoliative cytology in the diagnosis of cancer of the oesophagus is stressed. The examination uses a straightforward, economical technique and, in association with traditional investigations, offers diagnostic positivity of close to 100%. The interest in exfoliative oesophageal cytology does not derive solely from its confirmation of clinically certain oesophageal cancer, but from the fact that it offers early diagnosis outside of dysphagic symptomatology. Its field of use is thus extended and it proves to be a complementary but indubitably useful technique for diseases of the oesophago-gastric tract, particularly in those presenting high cancerization risk. Its use is therefore recommended for the screening of oesophageal cancer. | lld:pubmed |
