S0230 Goserelin in Preventing Ovarian Failure in Women Receiving Chemotherapy for Breast Cancer
RATIONALE: Goserelin blocks hormone production in the ovaries. It is not yet known whether ovarian suppression using goserelin will prevent ovarian failure (early menopause) in women receiving chemotherapy for breast cancer.
PURPOSE: This randomized phase III trial is studying how well giving goserelin together with chemotherapy works compared with chemotherapy alone in preventing early menopause in women with stage I, stage II, or stage IIIA breast cancer.
- Compare the rate of premature ovarian failure in women with stage I-IIIA hormone receptor-negative breast cancer treated with chemotherapy with vs without goserelin.
- Compare the rate of ovarian dysfunction in patients treated with these regimens.
- Compare ovarian reserve in patients treated with these regimens.
- Describe the pregnancy rates in patients treated with these regimens.
OUTLINE: This is a randomized study. Patients are stratified according to age (under 40 vs 40 to 49) and planned chemotherapy regimen (3- to 4-month/course anthracycline-based vs 6- to 8-month/course anthracycline-based vs 3- to 4-month/course non-anthracycline-based vs 6- to 8-month/course non-anthracycline-based). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive goserelin subcutaneously once every 4 weeks beginning 1 week before start of cyclophosphamide-containing chemotherapy. Treatment continues until completion of chemotherapy in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients receive cyclophosphamide-containing chemotherapy alone. Patients are followed at 1, 2, and 5 years.
PROJECTED ACCRUAL: A total of 416 patients (208 per treatment arm) will be accrued for this study within 3 years.

Medical and Biotech [MESH] Definitions
A synthetic long-acting agonist of GONADOTROPIN-RELEASING HORMONE. Goserelin is used in treatments of malignant NEOPLASMS of the prostate, uterine fibromas, and metastatic breast cancer.
17-Hydroxy-6-methylpregna-3,6-diene-3,20-dione. A progestational hormone used most commonly as the acetate ester. As the acetate, it is more potent than progesterone both as a progestagen and as an ovulation inhibitor. It has also been used in the palliative treatment of breast cancer.
Megestrol acetate is a progestogen with actions and uses similar to those of the progestogens in general. It also has anti-androgenic properties. It is given by mouth in the palliative treatment or as an adjunct to other therapy in endometrial carcinoma and in breast cancer. Megestrol acetate has been approved to treat anorexia and cachexia.

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
Primary Objective: - To determine the effectiveness of goserelin acetate (Zoladex) in preserving ovarian function in premenopausal women undergoing neoadjuvant and/or adjuvant che...
RATIONALE: Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as abiraterone acetate, leuprolide acetate, and goserelin, may lessen the amount of androgens...
The primary objective is to evaluate whether Zoladex 10.8 mg (12-weekly) is non-inferior to Zoladex 3.6 mg (4-weekly) in pre-menopausal women with oestrogen receptor positive advanced brea...

The primary purpose of this study is to establish if a 10.8 mg dose of ZOLADEX given 3 monthly is non-inferior to a 3.6 mg dose of ZOLADEX given monthly in terms of oestradiol suppression...
Superior outcome after neoadjuvant chemotherapy with docetaxel, anthracycline, and cyclophosphamide versus docetaxel plus cyclophosphamide: results from the NATT trial in triple negative or HER2 positive breast cancer.
The purpose of this study is to evaluate the efficacy and safety of docetaxel plus cyclophosphamide (TC) compared with docetaxel, anthracycline, and cyclophosphamide (TEC) in neoadjuvant treatment of...
Aim: The association of motilin, ghrelin, leptin, gastrin, pepsinogen (PG) I and II with cancer chemotherapy-associated dyspepsia syndrome (CADS) was investigated in 35 patients with breast cancer rec...
Despite the good responses of patients (pts) with stage III breast cancer to neoadjuvant chemotherapy (NAC), most eventually relapse and have a poor prognosis. We investigated the prognostic indicator...
Male breast cancer patients have a higher risk of developing a second primary cancer, but whether this risk differs according to the family history of breast or ovarian cancers remains to be elucidate...
In this paper we describe the case of a patient who underwent left breast radical mastectomy and corresponding removal of her axillary lymphonodes, for an infiltrating lobular cancer with massive colo...
