title: Activities of the Leeds Castle Polyposis Group.
abstract: In June 1985 an international meeting took place at Leeds Castle, England, to discuss some of the problems facing those caring for polyposis patients and conducting research in the field. From this grew the Leeds Castle Polyposis Group, comprising workers from 19 centers around the world; they agreed to cooperate initially in the collation of retrospective data with the hope that this would lead to prospective studies including comparative therapy trials. So far four retrospective pro formas have circulated. The data from these and plans for further projects will be discussed at the next meeting of the group in Washington in April 1987.
