简要总结
Gemcitabine and anthracycline combination has shown encouraging activity as neoadjuvant chemotherapy in locally advanced breast cancer. An addition of sequential gemcitabine and cisplatin, also a highly active combination in this indication, may result in improvement in pathological response and overall survival. Patients with operable breast cancer will be treated in neoadjuvant setting with gemcitabine plus doxorubicin, followed by gemcitabine plus cisplatin.

研究组 & 干预措施
Gemcitabine+Doxorubicin+Cisplatin+Surgery
Gemcitabine: 1200 mg/m^2, intravenous (IV) day 1 and day 8 every 21 days x 4 cycles (1-4) then 1000 mg/m^2, IV, day 1 and day 8 every 21 days x 4 cycles (5-8).
Doxorubicin: 60 mg/m^2, IV, every 21 days x 4 cycles (1-4). Cisplatin: 70 mg/m^2, IV, every 21 days x 4 cycles (5-8). Surgery follows 8 cycles of chemotherapy. Extent and type of surgery is guided by tumor size, physician and/or patient decision.

结局指标
主要结局
Number of Patients With Pathological Complete Response (Pathological Complete Response Rate)
时间窗: tumor assessment at baseline and during surgery after eight 21-day treatment cycles
Complete pathological response: No invasive tumor cells identified from sections from site of previous cancer. Require evidence corroborating prior presence of invasive cancer, which requires detection of abnormal fibroelastic breast stroma devoid of normal lobular units and contains foamy macrophages with moderate numbers of fibroblasts and mononuclear inflammatory cells. Presence of nondescript collagenised lobules or breast fibrous tissue is not evidence that tumor site has been adequately sampled and macroscopic assessment and sampling is needed until original neoplastic stroma identified.
次要结局
- Overall Survival(baseline to date of death from any cause up to 68 months)
- Time to Treatment Failure(baseline to stopping treatment (up to 68 months))
- Number of Patients Eligible for Breast Conservation Surgery at Baseline and Number of Patients Undergoing Breast Conservation Surgery(baseline, after eight 21-day cycles of study drug)
- Progression Free Survival (PFS)(baseline to measured progressive disease or death from any cause (up to 68 months))
- Summary of Deaths During Study(baseline through last cycle on study drug (eight 21-day cycles))
