61.   The clinical details and follow up of the seven patients in whom the diagnosis was based on cytology alone are given in Table V.

62.   This group of patients all followed a clinical course suggestive of malignancy with progressive deterioration and death in two to six months from the time of discharge.

63.   Insufficient follow up information was available in six of these patients.

64.   The time between bleed and randomisation as well as the measures required to stabilise patients was similar in both groups as was the length of follow up.

65.   Reproducible kinetic parameters such as these might be useful in planning follow up of patients with adenomatous polyps after polypectomy.

66.   Data from both baseline and follow up specimens are shown separately for the two subgroups.

67.   Milk derivatives were slowly reintroduced after one month of follow up in both groups.

68.   No differences were found in the cumulative relapse probability during follow up.

69.   In our present study, differences in relapse during follow up between both groups were not found, but relapse rate tended to be lower in the PEN group.

70.   This trend has to be confirmed with more patients and a longer follow up.
