- NCT00129935
- Lead Sponsor
- Spanish Breast Cancer Research Group
- Brief Summary
This is a prospective, randomised phase III trial, to compare the efficacy and safety profiles of two types of adjuvant chemotherapy regimens for human epidermal growth factor receptor 2 (HER2) negative, node positive breast cancer patients.
Control Arm: This includes 4 cycles of EC 90/600 mg/m2 day 1 every 3 weeks, followed by 4 cycles of T 100 mg/m2 day 1 every 3 weeks.
Experimental Arm: This includes 4 cycles of ET 90/75 mg/m2, day 1 every 3 weeks, followed by 4 cycles of capecitabine 1250 mg/m2, twice a day, via oral intake, for 14 days, and then a one-week rest period.
Premenopausal women with hormone receptor positive tumours must receive 5 years of tamoxifen after the end of chemotherapy.
Postmenopausal women with hormone receptor positive tumours can receive tamoxifen or aromatase inhibitors (or both) after the end of chemotherapy.
Patients may receive radiotherapy when clinically indicated.
- Detailed Description
Estimation of the 5-year disease-free survival in the control arm is 72%. The experimental arm is expected to increase the 5-year disease-free survival by 7% (up to 79%). With an alpha error of 0.05 and 80% power, 592 patients per arm are needed. Assuming a 17% post-randomization drop-out, 691 patients per arm are needed.

Complete stage workup during the 12 weeks prior to randomization (mammograms are allowed within a 20 week window). All patients must have a bilateral mammogram, thorax x-ray, abdominal echography and/or computed tomography (CT)-scan. If bone pain, and/or alkaline phosphatase elevation, a bone scintigraphy is mandatory. This test is recommended for all patients. Other tests: as clinically indicated.

- Prior radiotherapy for breast cancer.
- Bilateral invasive breast cancer.
- Pregnant or lactating women. Adequate contraceptive methods must be used during chemotherapy and hormone therapy treatments.
- Any T4 or M1 tumour.
- Axillary lymph nodes: patients belonging to the following classifications are excluded: TNM pathologic stage N1b, TNM pathologic stage N1c, TNM pathologic stage N2b, TNM pathologic stage N3b, TNM pathologic stage N3c.
- HER2 positive breast cancer (IHC 3+ or positive FISH result).
- Pre-existing grade >= 2 motor or sensorial neurotoxicity (National Cancer Institute Common Toxicity Criteria version 2.0 [NCICTC v-2.0]).
- Any other serious medical pathology, such as congestive heart failure; unstable angina; history of myocardial infarction during the previous year; uncontrolled hypertension or high risk arrhythmias.
- History of neurological or psychiatric disorders, which could preclude the patients from free informed consent.
- Active uncontrolled infection.
- Active peptic ulcer; unstable diabetes mellitus.
- Previous or current history of neoplasms different from breast cancer, except for skin carcinoma, cervical in situ carcinoma, or any other tumour curatively treated and without recurrence in the last 10 years; ductal in situ carcinoma in the same breast; lobular in situ carcinoma.
- Chronic treatment with corticosteroids.
- Contraindications for corticosteroid administration.
- Concomitant treatment with raloxifene, tamoxifen or other selective estrogen receptor modulators (SERMs), either for osteoporosis treatment or for prevention. These treatments must stop before randomisation.
- Concomitant treatment with other investigational products; participation in other clinical trials with a non-marketed drug in the 20 previous days before randomization.
- Concomitant treatment with another therapy for cancer.

- Primary Outcome Measures
Name Time Method Number of Participants With Disease-free Survival (DFS) Event 5 years A participant was considered to have had a DFS event if there was evidence of local, regional or metastatic recurrence, second primary cancer (with the exception of carcinoma of squamous cells or basal cells of the skin, cervical carcinoma in situ or lobular or ductal carcinoma in situ of the breast) or death for any reason.
- Secondary Outcome Measures
Name Time Method Number of Participants With Overall Survival (OS) Event Up to 5 years A participant was considered to have had a OS event if patient died from any cause.
Quality of Life Questionnaire: Time to Taking Off the Wig Up to 30 months Time to taking off the wig was assessed by a specific Hair Toxicity Questionnaire were patients answered when they stop to use the wig.
The questionnaire was evaluated up to two years after the end of chemotherapy.The Number of Participants Who Experienced Adverse Events (AE) 5 years Safety was assessed by standard clinical and laboratory tests, and were evaluated using NCI-CTC criteria v2.0
Quality of Life Questionnaire: Number of Participants With Hair Loss Up to 24 months Hair loss was assessed by the quality of life of the patients through the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Breast Cancer 23 (EORTC QLQ-BR23) profile questionnaire, question 4. The quality of life of the patients was evaluated before each cycle and at the end of treatment.
In questionnaire, raw scores range from 0 to 100 and a high score represents a high level of functioning or Health Related Quality of Life, excluding single-item scales in which high scores represent a high level of symptoms. A difference of 10 points on the scale over baseline value was classified as the minimum clinically meaningful change in both questionnaires.Quality of Life Questionnaire: Number of Participants With Hair Loss Recovery Up to 30 months Hair Loss Recovery was assessed by a specific Hair Toxicity Questionnaire were patients answered if the hair was less abundant than before, weaker than before or other.
The questionnaire was evaluated up to two years after the end of chemotherapy.
