Abstract
|
|
|
Thirty nine cases of multiple primary malignant tumors examined at the Department of
Pathology, Keimyung University School of Medicine during the period from November
1974 through March 1986 were analysed clinicopathologically.
The findings are as follows:
1) Thirty nine cases had synchronous lesion and six cases metachronous lesion. The
second primary malignancy occurred mean 4.7 years after the first malignancy in
patients with metachronous lesion.
2) The age at diagnosis of the first malignancy ranged from 26 to 76 years, the
average being 51.8 years. The male-female ratio was slightly less than 1:1.2.
3) The most commonly involved site in multicentric origin was gastrointestinal tract
(44.4%) with all adenocarcinoma and the second urogenital system (29.6%). In cases of
different tissues or organs (11 cases), ovary was the most frequent site (5 cases),
followed by cervix (4 cases).
4) Multiple primary malignant tumors of urogenital system were all eight cases and six
cases among them (75%) had smoking and drinking habits.
5) The detailed informations about possible environmental, familial and host factors
necessary for the investigation of multiple primary tumos were lacking in most cases.
Therefore, the history taking with special attention to these factors must be carefully
recorded. And also, we suggest that in the high-risk individuals, careful follow-up and
thorough search for early cancer detection or prevention should be taken.
