简要总结
The overarching purpose of this study is to determine if the mainstay chemotherapeutic regimens represented by several genotoxic agents including but not limited to Cyclophosphamide, Doxorubicin, Epirubicin, Fluorouracil and Methotrexate (CDEFM), in the format of either a single agent or combinations are safe, tolerable, and effective in the treatment of patients with infiltrating ductal carcinoma of breast.
详细描述
Infiltrating ductal carcinoma (IDC) of breast, or sometimes called invasive ductal carcinoma of breast, is the most common type of breast malignancy. About 80% of all breast cancers are IDCs.
Once found, IDC usually has already broken through the wall of the milk duct and begun to invade the tissues of the breast. Over time, IDC can spread to the lymph nodes and possibly to other areas of the body with high frequency.
According to the statistics of American Cancer Society, more than 180,000 women in the United States are diagnosed with IDC each year. Although IDC can affect women at any age, it is more common as they grow older. Further, approximately two-thirds of women are 55 or older when they are diagnosed with such this symptom.
The treatments for invasive ductal carcinoma fall into two broad categories. First, local treatments for IDC, including surgery and radiation, which treat the primary tumor and surrounding areas such as the chest and lymph nodes. Second, systemic treatments for IDC, including chemotherapy, hormone therapy and targeted therapy, which are supposed to deliver cytotoxicity throughout the body to eliminate any cancer cells that have left the primary site and to help minimize the risk of recurrent disease.
PURPOSE: This randomized phase I trial is to determine the safety, tolerability and efficacy of single or concurrent administration of cyclophosphamide, doxorubicin, epirubicin, fluorouracil and methotrexate (CDEFM) to women undergoing surgery for infiltrating ductal carcinoma in situ breast cancer.

研究组 & 干预措施
Mono-chemotherapy
A mono-chemotherapy (a single chemotherapeutic agent out of cyclophosphamide, doxorubicin, epirubicin, fluorouracil and methotrexate (or CDEFM) was performed 30~60 days prior to surgery for patients who had no history of receiving either local or systemic cancer-associated chemotherapy.
Interventions: cyclophosphamide, doxorubicin, epirubicin, fluorouracil or methotrexate.
干预措施: Single agent of cyclophosphamide, doxorubicin, epirubicin, fluorouracil and methotrexate (Drug)
Combined chemotherapy
Combined chemotherapy (random combination of two breast cancer chemotherapeutic agents including cyclophosphamide, doxorubicin, epirubicin, fluorouracil and methotrexate, or CDEFM) was performed 30~60 days prior to surgery for patients who had no history of receiving either local or systemic chemotherapy for cancer.
Interventions: cyclophosphamide, doxorubicin, epirubicin, fluorouracil or methotrexate.
干预措施: cyclophosphamide, doxorubicin, epirubicin, fluorouracil and methotrexate (CDEFM) (Drug)
Placebo treatment
No chemotherapeutic regimes using any cytotoxic agent was done for patients who have infiltrating ductal carcinoma of breast. Placebo was used instead.
干预措施: Placebo (Drug)
结局指标
主要结局
Incidence of treatment-emergent adverse events
时间窗: 6 months
The case of emergent events caused by treatment is measured by counting the blood cell number and detecting liver and kidney functions. Total blood cell number, alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and lactate dehydrogenase (LDH) \> 20% above upper limit of normal, is considered as not safe. Tolerability is measured by monitoring the first occurrence of grade 4 hematologic or grade 3-4 non hematologic toxicity as defined by the National Cancer Institute (NCI)-Common Toxicity Criteria (CTC) (NCI-CTC version 4; or CTCAE v4.0) and/or disruption of chemotherapy because of inacceptable toxicity. Chemotherapeutic efficacy is measured by the remaining tumor size after computed tomography (CT) scanning and comparing it with the original primary tumor size 2-3 weeks after last cycle of chemotherapy. The ratio of post-treatment tumor size to pre-treatment tumor size \< 50% is considered as effective. Otherwise not.
次要结局
