Statement: Fluorouracil, epirubicin, and cyclophosphamide (FEC) are used in both cohorts of the secondary trial, but not in cohort 1 of the primary trial.
Primary_evidence: INTERVENTION 1:    FSFI Total Score (Pretest)   Administered to participants prior to starting vaginal testosterone therapy. INTERVENTION 2:    FSFI Total Score (Postteset)   Testosterone USP micronized powder supplied by Medisca Pharmacy was compounded by Precision Compounding pharmacy as testosterone 0.3% per 0.5 milliliters (mL) in pharmabase cream. The compounded testosterone vaginal cream was supplied in pre-filled syringes and each 0.5 mL dose delivered 300 mcg of testosterone daily. The cream was applied to the vaginal opening once daily for four weeks (28 days).
Secondary_evidence: INTERVENTION 1:    FEC-75 Then Paclitaxel/Trastuzumab   Patients receive Fluorouracil, epirubicin, and cyclophosphamide (FEC) comprising fluorouracil IV, epirubicin hydrochloride IV, and cyclophosphamide IV on day 1. Treatment repeats every 21 days for 4 courses. Beginning 21 days after completion of FEC, patients receive paclitaxel IV once weekly and trastuzumab (Herceptin) IV once weekly for 12 weeks. Within 6 weeks after completion of paclitaxel and trastuzumab, patients undergo surgery. Beginning 3-4 weeks after surgery, patients receive trastuzumab IV once every 3 weeks for up to 52 weeks. epirubicin hydrochloride: Given IV, cyclophosphamide: Given IV, paclitaxel: Given IV, trastuzumab: Given IV, therapeutic conventional surgery: Undergo surgery, laboratory biomarker analysis: Correlative studies INTERVENTION 2:    Paclitaxel/Trastuzumab Then Trastuzumab/FEC-75   Patients receive paclitaxel IV once weekly and trastuzumab IV once weekly for 12 weeks. Beginning 7 days after the completion of paclitaxel and trastuzumab, patients receive FEC comprising fluorouracil IV, epirubicin IV, and cyclophosphamide IV on day 1. Treatment repeats every 21 days for 4 courses. Patients also receive trastuzumab IV once weekly for an additional 12 weeks. Within 6 weeks after completion of FEC and trastuzumab, patients undergo surgery. Beginning 3-4 weeks after surgery, patients receive trastuzumab as in arm I. epirubicin hydrochloride: Given IV, cyclophosphamide: Given IV, paclitaxel: Given IV, trastuzumab: Given IV, therapeutic conventional surgery: Undergo surgery, laboratory biomarker analysis: Correlative studies
