Active clinical trials for "Breast Neoplasms"

This is a two-year double blind, placebo-controlled, and randomized clinical trial, which is aimed to evaluate the effects of Chinese medical treatment on leucopenia after chemotherapy in breast cancer patients.

Background Seroma formation is a common problem after mastectomy. The incidence various between 30% to 92%. It is often an ongoing problem after removal of the suction drain, and repeated skin puncture is necessary to remove the seroma. In addition to many ambulatory visits this also leads to an increased risk of infection, and the adjuvant treatment can be delayed for several weeks Different procedures have been tried to avoid seroma formation. Among these are for ex. : immobilisation of the arm and shoulder after mastectomy, different drain regimens, closing of the dead space of the cavity, different chemical substances as thrombin, tranexamacid and fibrin. Non of these results has been successful. Seroma formation is most likely the result of the inflammatory response due to wound healing. In the seroma fluid several factors have been detected that support this assumption. These factors are: high levels of IgG, leucocytes, granulocytes, proteinases, proteinases inhibitors, different kinds of cytokines ( tPA, uPA,, uPAR, PAI-1, PAI-2, IL-6 og IL-1). On the basis of this, an inhibition of the inflammatory response might result in a decrease of seroma formation, and perhaps improve quality of life after mastectomy. Steroids inhibit the inflammatory response for example by inhibition of the cytokine function. It has been shown that a high single dose of steroid infusion (30mg/kg solu-medrol) inhibits the normal IL 6 response after colon resection. Newer studies have shown that even at a lower dose the inflammatory response is inhibited. In several studies of head and neck surgery the oedema in surgical area is reduced after a single dose of 125 mg solumedrol. It is precisely this effect of reduced fluid formation we want to obtain in our study. We have therefore chosen to use a single dose of 125 mg of solumedrol in this study. Even at the largest single dose of glucocorticoids there have not been seen any increasing in surgical complications. The aim of the study: To find out whether single dose of glucocorticoid can reduce the seroma formation after mastectomy Study design : A randomised pilot study, with 2 x 20 patients. 125 mg solumedrol is given 1,5 hours before surgery in 20 patients, and the other 20 patients are the control group Inclusion criteria: Women with primary breast cancer, undergoing a mastectomy with either sentinel node biopsy or complete axillary dissection.

RATIONALE: Radiation therapy uses high-energy x-rays or other types of radiation to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether radiation therapy is more effective than observation after mastectomy in treating women with stage II breast cancer. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with standard therapy in treating women with stage II breast cancer who have undergone mastectomy.

The investigators' proposed phase 2 clinical trial will be an open-label, non-randomized study among 80 women with metastatic breast cancer. The study treatment period will be up to twelve months and enrollment will be open at 10-15 clinical sites in the United States. In this Phase 2 trial, 40 participants with hormone receptor positive tumors and 40 with hormone receptor negative tumors will be enrolled and treated with BZL101 20 grams/day (10 grams BID). Hormone receptor positive will be defined as estrogen receptor (ER)+ and progesterone receptor (PR)+, ER+ and PR-, or ER- and PR+. Hormone receptor negative will be defined as ER- and PR-.

RATIONALE: Studying samples of blood from patients with breast cancer in the laboratory may help doctors identify and learn more about biomarkers related to tamoxifen resistance. PURPOSE: This laboratory study is looking at tamoxifen resistance in women with stage I, stage II, stage IIIA, or stage IIIB breast cancer.

The purpose of this study is to assess Efficacy and Safety of Extended Adjuvant Treatment With Letrozole in Postmenopausal Women With Hormone Receptor Positive Breast Cancer Who Complete 5 Years of Toremifene

The purpose of the study is to demonstrate equivalent pharmacokinetics (PK)

In post-menopausal metastatic hormone-responsive breast cancer women. This study is a two arm randomized trial to evaluate the effectiveness of dose-titration regimen of fulvestrant compared with the approved dosing regimen. Patients will be randomized to one of the following treatment arms: Arm A: Fulvestrant 500 mg days 0, 14, 28, then 250 mg every 2 weeks for 5 administrations, then 250 mg every 28 days, until progression or unacceptable toxicity Arm B: Fulvestrant 250 mg every 28 days until progression or unacceptable toxicity

Endocrine therapy is the mainstay of systemic treatment in patients with endocrine responsive breast cancer. Aromatase inhibitors are the most active agents in post-menopausal women. Randomized comparisons either in primary/adjuvant setting or in metastatic disease setting have demonstrated the superiority of these drugs over tamoxifen. Primary systemic treatment administered to breast cancer patients is a useful model to identify baseline features able to predict which patients are most likely to benefit from cytotoxic treatment and is a way to study new biological markers in relation to the predictive information they provide. This treatment modality represents therefore the best way to explore new treatment strategies in particular treatment strategies involving target therapies. We have conducted a randomised phase II trial in which the activity of Letrozole plus/minus oral metronomic cyclophosphamide as primary systemic treatment has been investigated in a patient population of elderly breast cancer patients. The conclusions were that the combination of letrozole with metronomic cyclophosphamide was a very active scheme. In addition this was the first study demonstrating in vivo the antiangiogenic effect of metronomic scheduling. This study suggests that chemotherapy administered on a metronomic schedule, targeting therefore the neo-angiogenesis, could be synergistic with endocrine therapy with aromatase inhibitors. Sorafenib is a multi-kinase inhibitor targeting Raf, VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-alfa, Flt-3, c-Kit, and p38. There is a strong rationale of combining different anti-angiogenic agents. At the ASCO 2007 meeting the data of a phase I study exploring the toxicity of a combination of sorafenib and bevacizumab have been presented. The results showed an increased toxicity being dose limiting in some patients. To our knowledge there are no data un activity and toxicity of adding sorafenib to metronomic chemotherapy.

This study compares two different field set-ups in patients with breast cancer following a breast resection (mastectomy). These two set-ups are as follows: arm a - radiotherapy to the chest-wall only, and arm b - radiotherapy to the chest-wall and the supraclavicular fossa. Patients in both treatment arms will receive radiotherapy with a shortened fractionation schedule. Study hypothesis: irradiation of the chest-wall only is not inferior to irradiation of the chest-wall and supraclavicular fossa in terms of loco-regional control, survival and treatment toxicity.
