Abstract

Purpose

The aim of this study is to evaluate the relationship of menopause and serum follicle stimulating hormone (FSH) level and estradiol (E2) in Korean women with breast cancer.

Methods

We reviewed 1,404 women aged from 20- to 82-year-old (median 47 years) with breast cancer who had got surgery at Asan Medical Center in 2008. All patients were checked serum FSH before the operation. Three hundred fifty-three patients were in postmenopause state at the time of surgery. Their ages were from 40- to 60-year-old (median 50.3 years).

Results

The proportion of postmenopausal status in each age-group were 5.1% (45- to 49-year-old), 41% (50- to 54-year-old), 86.1% (55- to 59-year-old), and 100% over the age of 60, respectively. And the proportion of the patients with FSH over 30 mUI/mL were 68.6% (45- to 49-year-old), 87.5% (55- to 59-year-old), 75.0% (55- to 59-year-old) and 30.0% (over the age of 60), respectively.

Conclusion

Our study shows that even though patients had been in amenorrhea over 1 year, not all patients have their FSH level over 30 mUI/mL. And this finding is more prominent in age group from 45- to 49-year-old.

Keywords: Breast neoplasms, Follicle stimulating hormone, Menopause

Figures and Tables

Figure 1

Proportion of menopausal status. The histograms is displayed proportion of menopausal status according to age groups.

Figure 2

Proprotion of menopausal status according to age of 50-60. The histograms is subdivided 50th age group in Figure 1, and displayed proportion of menopausal status according to age.

Figure 3

Proportions of FSH ≥30 according to age group in postmenopausal patients. It is displayed proportion of FSH over 30 mIU/mL in patients who had been ammenorrhea over 1 yr.

FSH=follicle stimulating hormone.

Figure 4

Proportions of E2 ≤20 according to age group in postmenopausal patients. It is displayed proportion of E2 less than 20 mIU/mL in patients who had been ammenorrhea over 1 yr.

E2=estradiol.

Figure 5

Proprotion of FSH ≥30 and E2 ≥20 according to age group in postmenopausal patients. It is displayed proportion of FSH more 30 mIU/mL and E2 less than 20 mIU/mL patients who had been ammenorrhea over 1 yr.

FSH=follicle stimulating hormone; E2=estradiol.
