Background Endoscopic cancer surveillance has been advocated for patients w
ith Barrett's oesophagus. However, only a small minority of patients dies f
rom adenocarcinoma in Barrett's oesophagus. It has been calculated that end
oscopic cancer surveillance will only add to the quality of life of individ
uals in whom the incidence of adenocarcinoma in Barrett's oesophagus is gre
ater than 1/200 patient-years.
Objective To determine the proportion of a consecutive cohort of patients,
in whom Barrett's oesophagus was diagnosed over a 5-year period, likely to
benefit from endoscopic cancer surveillance.
Methods All patients who had died during the observation period or were ove
r 75 years old and those with diseases likely to impair survival were exclu
ded. Next, all patients in whom the risk of developing adenocarcinoma in Ba
rrett's oesophagus fell below 1/200 patient-years were excluded (including
all women, all men under the age of 60 and all men with Barrett's oesophagu
s of < 3 cm in length). Patients with dysplasia of any degree and/or presen
ce of an ulcer or stricture in Barrett's oesophagus were reinstated.
Results Of 335 adult patients diagnosed with Barrett's oesophagus but witho
ut adenocarcinoma or high-grade dysplasia, 75 had died from unrelated cause
s, 47 had other diseases limiting survival and 59 were over 75 years old. A
fter exclusion of all women, all men with Barrett's oesophagus of < 3 cm in
length and all men under 60 years old, 15 patients were left. However, 32
were reinstated because of risk factors and another five because of insuffi
cient data, resulting in 52 of the original 335 patients (15.5%) being elig
ible for endoscopic cancer surveillance.
Conclusion This study suggests that less than 20% of patients identified wi
th Barrett's oesophagus at routine endoscopy would benefit from endoscopic
cancer surveillance. Prospective surveillance programmes should be limited
to patients with an increased cancer risk and a good health profile. Eur J
