About this study

Official title: Effect of Light Alcohol Intake on Sex Hormone Levels Among Postmenopausal Women With ER+ Breast Cancer on Aromatase Inhibitor Therapy: The Alcohol and Breast Cancer (ABC) Trial

This research study is a pilot study, which is the first time investigators are examining the effect of light alcohol consumption on sex hormones among postmenopausal women with estrogen receptor-positive (ER+) breast cancer taking an aromatase inhibitor

The names of the study exposures involved in this study are:

  • White wine
  • White grape juice
Read the detailed description

This research study is trying to to help understand whether light alcohol consumption causes short-term changes in the levels of estrogen, progesterone and testosterone, called sex hormones, among postmenopausal women with estrogen and/or progesterone receptor positive breast cancer taking estrogen-blocking medications called aromatase inhibitors.

The research study procedures include one screening visit to obtain informed consent, four study visits with blood draws, and ten weekly phone calls and online questionnaires over the ten weeks of the study.

This research study involves 10 weeks of participation, including 3 weeks consuming one serving of white wine daily, 3 weeks consuming one serving of white grape juice daily, and 2 weeks of drinking neither alcohol nor grape juice before each of these 3-week drinking periods.

In this experimental study, participants will be asked to drink white wine and white grape juice, which are not consumed as the standard of care. The U.S. Food and Drug Administration (FDA) has not approved alcohol as a treatment for any disease.

It is expected that about 20 women will take part in this research study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Blood Levels of Total Estradiol Concentration

    Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.

    Measured: 3 Weeks

Secondary outcomes (6)
  1. Blood Levels of Free Estradiol Concentration

    Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period. Estimates of free estradiol concentration were calculated using Mazer transformation.

    Measured: 3 weeks

  2. Blood Levels of Free Estradiol Index

    Estimated as total estradiol concentration divided by SHBG levels.Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.

    Measured: 3 weeks

  3. Blood Levels of Estrone Concentration

    Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.

    Measured: 3 weeks

  4. Blood Levels of Dehydroepiandrosterone Sulfate (DHEAS)

    Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.

    Measured: 3 Weeks

  5. Blood Levels of Testosterone

    Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.

    Measured: 3 Weeks

  6. Blood Levels of Sex Hormone Binding Globulin (SHBG)

    Blood levels were measured at the beginning and end of three weeks of one serving (5 ounces) of white wine daily and the beginning and end of three weeks of one serving of white grape juice (6 oz) daily, with a two-week washout period before each drinking period. Estimates for levels following three weeks adjusted for blood levels at the beginning of the drinking period.

    Measured: 3 Weeks
