What was measured

Adjuvant! is not currently available; additional work combining classical information with genomic tests will be reported separately.

Analysis population: Outcome will never be analyzed.

Groups in this outcome

Arm A

Group 1 (Oncotype DX recurrence score =\< 10): Patients in this group receive hormone therapy with tamoxifen, anastrozole, letrozole, or exemestane PO for up to 5 years. Some patients then continue to receive hormone therapy for an additional 5 years. Anastrozole: Given PO Exemestane: Given PO Letrozole: Given PO Tamoxifen: Given PO

Arm B

Group 2 (Oncotype DX recurrence score 11-25): Patients receive hormone therapy with tamoxifen, anastrozole, letrozole, or exemestane PO for up to 5 years. Some patients then continue to receive hormone therapy for an additional 5 years. Anastrozole: Given PO Exemestane: Given PO Letrozole: Given PO Tamoxifen: Given PO

Arm C

Group 2 (Oncotype DX recurrence score 11-25): Patients receive standard combination chemotherapy at the discretion of the treating physician. Within 4 weeks after the last dose of chemotherapy, patients receive hormonal therapy as in Group 1 at the discretion of the treating physician. Anastrozole: Given PO Exemestane: Given PO Letrozole: Given PO Tamoxifen: Given PO Combination chemotherapy: including oral CMF, IV CMF, standard AC, dose dense AC, standard AC-T, dose dense AC-T, FEC, TAC, TC, other protocol-specified regimens if participating in other CTSU trials including chemotherapy, and other regimens not protocol-specified if not participating in CTSU trials

Arm D

Group 3 (Oncotype DX recurrence score \>= 26): Patients in this group receive combination chemotherapy followed by hormone therapy similar to the patients in Group 2 who are assigned to receive both types of treatment. Anastrozole: Given PO Exemestane: Given PO Letrozole: Given PO Tamoxifen: Given PO Combination chemotherapy: including oral CMF, IV CMF, standard AC, dose dense AC, standard AC-T, dose dense AC-T, FEC, TAC, TC, other protocol-specified regimens if participating in other CTSU trials including chemotherapy, and other regimens not protocol-specified if not participating in CTSU trials
