Abstract
|
|
|
In 1968 The Korean Society of Pathology (authored by Chae Koo Lee, Sang Kook Lee.
Sang In Kim and Je G. Chi et al) presented the first nationwide data on cancer
prevalence among Koreans, based on 22,208 biopsy and autospy cases during a 10 year
period of 1958 to 1967. Since that time there has been a multitude of factors that might
have influenced on the cancer prevalence among Koreans. In this study, an analysis was
made on 7,363 consecutive cases of primary malignant tumors, all diagnosed
microscopically at the Department of Pathology, College of Medicine. Seoul National
University, Seoul, Korea, during a 10 year period from January 1968 to December 1977.
The great majority of the cases of this study were specimens from in-patients and
out-patients of Seoul National University Hospital, and some were from outside hospitals
sent for the confirmative diagnosis. Hematological diagnoses were made by staffs of
Department of Clinical Pathology Seoul National University Hospital. Metastatic tumors
were excluded from the statistics. The description of tumor of each case was made in a
punch card. These cards were classified according to the World Health Organization
code numbers of diseases and other items including those of each calender year, sex
and the age distributions. And the results were tabulated.
The following analyses were male.
1. The total number of malignant tumors included in this study was 7,363.
There were 3,662 cases of male (49.7%) and 3,663 cases of female (49.7％).
2. The mean age of the patients with cancer was 46.6 years; 47.1 years in male and
45.6 years in female.
3. The frequency ranks of malignant tumors in male, female and both sexes are listed
in Table 1. Among all malignant tumors in both sexes together, the relative frequency
in percentage is cancer of the stomach (16.65％), uterine cervix cancer (15.08％),
leukemia (6.51％), liver cancer (5.62％), breast cancer (5.53％), skin cancer (4.29％),
thyroid cancer (4.13％), malignant lymphoma (4.03％), rectal cancer (3.92%) and larynx
cancer (3.72%) in decreasing order of frequency.
4. Among all malignant tumors in male the relative frequency in percentage is stomach
cancer (22.23%), liver cancer (8.98％), leukemia (8.36%), laryngeal cancer (6.19%), skin
cancer (5.65%), malignant lymphoma (5.19%), lung cancer (4.4％), urinary bladder cancer
(4.23%) and bone cancer (3.25%) in decrasing order of frequency.
5. Among all malignant tumors in female the relative frequency in percentage is uterine
cervix cancer (39.3%), stomach cancer (11.0%), breast cancer (10.89%), thyroid cancer (6.
67％), leukemia (4.72%), rectal cancer (3.41%), malignant lymphoma (2.89%), skin cancer
(2.87%), ovary cancer (2.6%) and uterine body cancer (2.46%) in decreasing order of
frequency.
6. The age distribution of the malignant tumors shows the highest frequency in the
sixth decade in male and the fifth decade in female.
7. Generally, the annual identification of total malignant tumors shows a tendency of
gradual increase since the first year of the study. An increasing trend appears definite
in breast cancer, thyriod cancer, liver cancer particularly in female, and a decreasing
trend is suggestive in cancer of uterine cervix and malignant lymphoma,
