OESOPHAGEAL CANCER

The Oesophageal Cancer belt stretches from the Caspian Sea to the
north of China. It also includes Afghanistan and North West of Pakistan
where we see patients. Oesophageal Cancer in Afghan population (males and
females) ranked fourth in our study. Chinese have also done some studies
themselves as well as with National Cancer Institute USA (NCI)
collaboration, where supplements of vitamins were given and we were told
that the incidence of Oesophageal Cancer decreased. It will be interesting
to know whether the authors of the article on “Vitamin supplements do not
cut risk of gastrointestinal cancer” took the Chinese and the NCI studies
into consideration before arriving at the conclusion.
