[Recurrences of adenomas of the large intestine]. 1985

V L Rivkin, and M V Khakhanova, and Iu N Egorov

A retrospective mathematic-statistical evaluation of cases of adenoma of the large intestine--asymptomatic (group 1) or bleeding one (group 2)--showed the frequency and pattern of recurrence and malignant transformation following electrocoagulation to be identical in both groups. Such change in the histologic type as transformation of tubular polyps to a villous pattern proved to be an important factor of risk for relapse and neoplastic growth of solitary adenoma of the large intestine. Villous adenoma showed the highest rate of recurrence and malignant transformation. It is considered to be obligatory precancer.

UI	MeSH Term	Description	Entries
D007417	Intestinal Polyps	Discrete abnormal tissue masses that protrude into the lumen of the INTESTINE. A polyp is attached to the intestinal wall either by a stalk, pedunculus, or by a broad base.	Intestinal Polyp,Polyp, Intestinal,Polyps, Intestinal
D009364	Neoplasm Recurrence, Local	The local recurrence of a neoplasm following treatment.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
