Intervention model description: This is a one-stage phase II study with a single arm design. All patients will receive 4 cycles of epirubicin + cyclophosphamide followed by paclitaxel +carboplatin for four cycles in the neo-adjuvant setting. Those with clinical response (assessed via breast ultrasound), will undergo surgery. After surgery, all patients who achieve pCR will undergo radiotherapy. Patients with pathological incomplete response or stable disease may have additional chemotherapy at the discretion of the managing physician.
Primary purpose: TREATMENT

Brief summary: Triple negative breast cancer (TNBC) is an aggressive disease with higher proportion of Blacks affected and in younger age groups. There is no targeted therapy unlike other types of breast cancer such as hormone positive and Human Epidermal Growth factor 2 (HER2) positive subtypes. Chemotherapy is therefore the main choice of systemic treatment with rapid development of resistance in most cases. At present, there is no blood test to monitor treatment response and disease relapse. This one-stage phase II study with a single arm design will determine the response rate of standard chemotherapy using Epirubicin (60mg/m2), Cyclophosphamide (600mg/m2) , Paclitaxel (120mg/m2) and Carboplatin (6AUC) in TNBC patients. We will measure the blood level of microRNA molecules and circulating tumor DNA during and after treatment to test if changes can be used to indicate drug failure in these patients. Disease status and tumor response will be assessed using Response Evaluation Criteria in Solid Tumors (RECIST) guidelines while toxicity will be assessed using CTCAE v5). The trial will be conducted as per the International Council on Harmonisation Good Clinical Practice (ICH GCP) Guidelines E6 (R1) and other applicable guidelines

Detailed description: Triple negative subtype of breast cancer (TNBC), accounts for about 55% of all breast cancer among indigenous blacks, such as Nigerians, and younger women are more susceptible Patients with TNBC generally experience a more aggressive clinical course with faster disease progression and poorer overall survival. There is no targeted treatment available beyond conventional cytotoxic chemotherapy . Unfortunately, standard chemotherapy is only effective in about 40% of patients with pathological complete response (pCR) achieved only in 20%-30% . Local relapse occurs early. Therefore, chemo-resistance is the main cause of chemotherapeutic failure and leads to suboptimal response rates . There are no biomarkers of response for close monitoring of TNBC patients to identify chemotherapy failure early. This one-stage phase II study with a single arm is designed to assess the response rate and toxicity of Epirubicin-Cyclophosphamide with Paclitaxel-Carboplatin (ECPC) and examine the potential of using circulating microRNa and circulating tumor cells as a surrogate marker of chemotherapy resistance in Nigerian women with triple negative breast cancer. A total of 42 patients will be enrolled into the trial. Each participant will receive Epirubicin (60mg/m2), Cyclophosphamide (600mg/m2) , Paclitaxel (120mg/m2) and Carboplatin (6AUC) . Blood microRNA and circulating tumor DNA will be determined before and after therapy. Tumor response will be measured by breast ultrasound and described using RECIST criteria while toxicity will be graded using CTCAE criteria. Quality of life (QoL) of participants while on chemotherapy will also be assessed using EORTC quality of life questionnaire - (General and Breast cancer specific).

Eligibility criteria: Inclusion Criteria:

5. Clinical stages IIA -IIIC (AJCC 2009)
6. Chemotherapy-naïve patients (for this malignancy)
7. Performance status: Eastern Cooperative Oncology Group (ECOG) performance status 0-1
8. Non-pregnant and not nursing. Women of childbearing potential must take the pregnancy test and must commit to receive Leuteinizing Hormone Realising Hormone (LHRH) agonist Zoladex (goserelin) for two years starting from the commencement of the study medications
9. Required Initial Laboratory Data. Adequate hematologic, renal and hepatic function, as defined by each of the following:

1. Granulocyte ≥ 1,500/μL 2. Platelet count ≥ 100,000/μL 3. Absolute neutrophil count (ANC) ≥ l500/μL 4. Hemoglobin ≥ 10g/dL 5. Bilirubin ≤ 1.5 x upper limit of normal 6. SGOT and SGPT \< 2.5 x upper limit of normal 7. Creatinine within institutional normal limits or glomerular filtration rate ≥ 30 mL/min/1.73 m2 by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) (CKD EPI) equation (see http://mdrd.com/ for calculator) 10. Echocardiogram (ECHO): Baseline left ventricular ejection fraction of ≥ 55%

Exclusion Criteria:

1. Pregnant or lactating women. Women of childbearing potential not using a reliable and appropriate contraceptive method. Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-childbearing potential.
2. Patients with distant metastasis (brain and/or visceral metastasis)
3. Serious, uncontrolled, concurrent infection(s).
4. Treatment for other carcinomas within the last 5 years, except non-melanoma skin cancer and treated cervical carcinoma in-situ (CCIS)
5. Participation in any investigational drug study within 4 weeks preceding the start of study treatment
6. Other serious uncontrolled medical conditions that the investigator feels might compromise study participation including but not limited to chronic or active infection, HIV-positive patient, uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, uncontrolled Diabetes mellitus, or psychiatric illness/social situations that would limit compliance with study requirements.
