Dear Editor
As someone who did some basic research in oesophageal cancer on
retirement in 1997, I am very much in agreement with the authors' doubts
of the likelihood of oesophageal cancer being a common cause of dysphagia
in adults. On retirement, I performed an audit on the disease and found
the incidence of new cases being 3600 over 5 years in a population in the
West Midlands of about 5 million. (Incidence about 0.0014).
The authors are to be commended for their scientific content but not
their grammar. The subtitle "These greatly increase the risk of cancer,
but the diagnosis is still rare", is irritating. The symptoms do not
increase the risk of cancer. May I suggest: Alarm symptoms are increased
in patients who happen to have to have cancer, but the diagnosis is still
rare?
Yours sincerely,
Walford Gillison FRCS
