Population-based Breast Cancer Statistics in Korea during 1993-2002: Incidence, Mortality, and Survival

Abstract

In 2002, breast became the most common cancer site in Korean women. Using national breast cancer incidence data during 1993-2002, crude, age-standardized, and age-specific rates for incidence and mortality were calculated. Survival was examined for cases diagnosed during 1993-2002 and followed up to 2004. Observed survival was calculated using the life table method and relative survival using the Ederer II method. Age-standardized incidence rates in female increased from 14.5 in 1993 to 26.2 per 100,000 in 2002. Age-specific incidences showed peaks in women in their forties. Mortality rates increased from 3.7 in 1993 to 4.6 per 100,000 in 2002 and showed peaks in women in their fifties. Five-year relative survival for female breast cancer diagnosed during 1993-2002 was 82.2%. When we examined the secular trends using cases diagnosed 1993-1999 for complete 5-yr follow-up, the 5-yr relative survival increased from 75.2% in 1993 to 83.5% in 1999. The data from this study will provide valuable information to plan and evaluate actions against breast cancer including national breast cancer screening.

“…50 Considering the size of the tumor, the diagnosis of breast cancer tends to be performed by self-examination with the tumor greater than 2.0 cm, varying between 2.0 and 5.0 cm. 8,14,20,38,43 This result demonstrates the difficulty for the healthcare systems to diagnose breast cancer in the early stages, especially with the absence of metastasis, when the disease is easy to control and potentially curable.…”

“…The publications originated from 20 countries: Korea (six studies), [8][9][10][11][12][13] Japan (five studies), [14][15][16][17][18] Brazil (four studies), 3,[19][20][21] Canada (three studies), [22][23][24] United States (three studies), [25][26][27] Italy (three studies), [28][29][30] Switzerland (three studies), [31][32][33] France (two studies), 34,35 China (one study), 36 Singapore and Sweden (one study, study performed in both countries), 37 Scotland (one study), 38 Spain (one study), 39 Finland (one study), 40 India (one study), 41 England (two studies), 42,45 Mexico (one study), 43 Poland (one study), 44 and the Netherlands (one study). 46 From the aim established for this study, the variables to be investigated were defined: the study design, study site/country, number of subjects, age of the subjects, five year survival rate, disease-free five year survival rate, factors that contribute to the increase in survival rates.…”

Serum High-Density Lipoprotein Cholesterol and Breast Cancer Risk by Menopausal Status, Body Mass Index, and Hormonal Receptor in Korea

“…We enrolled a large number of premenopausal cases. In Korea, age groupspecific breast cancer incidence is the highest in the 45-to 49-year-old group and decreases as age increases, and this trend has been more definite in recent years (47). Birth cohort effect is suggested to be contributed to this unique pattern, which can be explained by westernization and higher obesity.…”

Increased Risk for Second Primary Malignancies in Women with Breast Cancer Diagnosed at Young Age: A Population-Based Study in Taiwan

“…Intriguingly, during the past two decades, the median age at first diagnosis of female breast cancer has remained at 45 to 49 years in Asian countries such as Taiwan (4,6), China (6), Korea (7), and Japan (8,9), which is at least 10 years younger than their counterparts in Western countries and Australia (>60 years; refs. [10][11][12].…”
