Valproic Acid in Combination With FEC100 for Primary Therapy in Patients With Breast Cancer
Keywords
Abstract
Description
Each year, more than 200,000 patients are diagnosed with breast cancer. While recent advances in diagnosis and treatment have rendered a large proportion of these patients curable, many patients still present with either locally advanced or metastatic breast cancer that is not amenable to potentially curative surgery. To enhance the chance of complete surgical resection of the tumor, patients with very large, locally advanced or inflammatory breast cancer will be offered neo-adjuvant therapy.
The use of systemic chemotherapy after the surgical therapy for patients with operable disease has been associated with a 25%-35% reduction in the risk of systemic relapse (Early Breast Cancer Trialists' Collaborative Group, 1998) Administration of chemotherapy prior to surgery, also referred to as neoadjuvant chemotherapy is often used in patients with inoperable, non-metastatic breast cancer. However more recently, neoadjuvant therapy has become more commonly used as it allows the direct assessment of response to systemic therapy and the collection of biological markers of therapy that are otherwise difficult to obtain. Furthermore, the relative high response rate allows the ability to surgically remove the tumor and achieve adequate tumor-free margins.

Eligibility Criteria
| Ages Eligible for Study | 18 Years To 18 Years |
| Sexes Eligible for Study | All |
| Accepts Healthy Volunteers | Yes |
| Criteria | Inclusion Criteria: - Patients must have histologically or cytologically confirmed diagnosis of breast cancer - Patients must have "locally advanced" adenocarcinoma of the breast: - tumors > 2 cm without lymph node involvement (negative sentinel lymph node mapping) - tumors > 2 cm with lymph node involvement (either by positive sentinel lymph node mapping or FNA of palpable lymph node) - tumors of any size that show extension to the chest wall or skin, including edema, ulceration, or satellite skin nodules - inflammatory carcinoma (stage IIIB) that is amenable to surgery - tumors of any size associated with ipsilateral internal mammary nodes (stage IIIB) - tumors of any size associated with ipsilateral supraclavicular lymph nodes (IIIC) without other evidence of systemic metastases - patients may have bilateral breast cancer if both breasts are assessible for response - Age >18 years - Because no dosing or adverse event data are currently available on the use of VPA in combination with FEC100 in patients <18 years of age, children are excluded from this study - ECOG performance status 0 or 1 (Karnofsky >80%) - Patients must have normal organ and marrow function as defined below: - leukocytes >3,000/mcL - absolute neutrophil count >1,500/mcL - platelets >100,000/mcL - total bilirubin within 1.5 x normal institutional limits - AST(SGOT)/ALT(SGPT) <2.5 X institutional upper limit of normal - Creatinine within normal institutional limits - VPA has been associated with neural tube defects in the developing human fetus, for this reason and because FEC100 used in this trial are also known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Participating men must use condoms while on study and for at least 3 months after the trial has ended. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. - Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria: - Patients may not have had any prior chemotherapy within the last 2 years - Patients may not have been exposed to prior anthracyclines - Patients may not be receiving any other investigational agents - Patients with known brain metastases are excluded - History of allergic reactions attributed to compounds of similar chemical or biologic composition to VPA or FEC100. - Patients with known congestive heart disease or LVEF fractions of <50 % (past or current), patients with known ventricular arrhythmias - Patients taking VPA as an anti-seizure agent or for any other indications - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. - Due to the teratogenic effects of VPA and FEC100, pregnant or lactating women are excluded from the study. |
