Description of intervention(s) / exposure
IBCSG 26-02 / BIG 4-02 (PERCHE) is being conducted internationally by the International Breast Cancer Study Group (IBCSG). The study is coordinated in Australia and New Zealand by the Australian and New Zealand Breast Cancer Trials Group (ANZ BCTG).

This trial will evaluate the worth of adding adjuvant chemotherapy for premenopausal women with steroid hormone receptor positive early invasive breast cancer who receive ovarian function suppression plus either tamoxifen or exemestane for 5 years. The use of chemotherapy will be determined by randomization. The method of ovarian function suppression (GnRH analogue for 5 years, surgical oophorectomy or ovarian irradiation) and the choice of tamoxifen or exemestane will be determined by the investigator.

IBCSG 26-02 / BIG 4-02 (PERCHE) is an international, multicentre, randomised phase III clinical trial of 1750 premenopausal women who have had histologically or cytologically confirmed, receptor-positive primary breast cancer for whom there is an uncertain role for adding chemotherapy to the adjuvant treatment program.

Women will be randomised in a 2-arm design to receive one of the following:

a. Chemotherapy + Ovarian Function Suppression (triptorelin) + Tamoxifen/Exemestane
b. Ovarian Function Suppression (triptorelin) + Tamoxifen/Exemestane
All hormonal treatment will be for 5 years.

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The ANZ BCTG Statistical Centre at the NHMRC Clinical Trials Centre, University of Sydney will provide a central randomisation service by fax for all Australian and New Zealand institutions. At the time of study entry all participants will be allocated a treatment code via a web-based randomization system and study drug will be supplied in accordance with the treatment code.

Summary
Brief summary
Estrogen can stimulate the growth of breast tumor cells. Suppression of ovarian function combined with hormone therapy may fight breast cancer by reducing the production of estrogen. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known whether suppression of ovarian function and hormone therapy are more effective with or without chemotherapy in treating breast cancer.
This randomized phase III trial is studying how well giving ovarian-function suppression together with hormone therapy and chemotherapy works compared to ovarian-function suppression and hormone therapy alone in treating premenopausal women with resected breast cancer.
