Filter by:The purpose of this study is to determine if this combination is safe and effective in this situation especially to increase the rate of pathological complete response (PCR). Women with large tumors and or lymph node involvement at the time of initial diagnosis may benefit from receiving chemotherapy prior to surgery to shrink the tumor and to decrease the amount of tumor involvement before surgery. If chemotherapy given before breast surgery is effective in decreasing the size of the tumor, breast conserving surgery (lumpectomy) may be possible. This new combination may be better tolerated than other commonly used regimens and, to date, appears to be at least as effective.
hypothesis: 10 Gy additional boost to the tumor bed will yield an increase in local control at 10 years from 88% to 93%, with still acceptable cosmesis.
The main objective of this randomized trial is to compare 6 FEC100 to 4 FEC100 + 4 Taxol in patients with resected node positive breast cancer. Main endpoint is disease free survival. Secondary endpoints are overall survival, time to local recurrence, time to distant metastases, and tolerance. A total of 840 patients have been included in the trial.
To determine whether an accelerated course of radiotherapy delivered to the lumpectomy cavity plus margin using IORT as a single dose, intracavitary brachytherapy with the MammoSite device over 5 days, partial breast 3-D CRT in 5 days, or stereotactic APBI over 4 days is a feasible and safe alternative to a six and a half week course of whole breast radiotherapy. The study will measure both short and long-term complications of radiation treatment, short and long-term breast cosmesis, local rates of in-breast cancer recurrence, regional recurrences, distant metastases, and overall survival.
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation during surgery may be an effective treatment for breast cancer. PURPOSE: This phase II trial is studying how well radiation therapy works in treating older women who are undergoing surgery for invasive breast cancer.
Prevalence of chronic pain after mastectomy is beyond 50% 3 months after surgery. This pain is related to a sensitization of the central nervous system through N-methyl-D-asparate (NMDA) receptors. Ketalar might prevent the occurrence of chronic pain by anti-NMDA properties after mastectomy.
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using fulvestrant or tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving fulvestrant or tamoxifen before surgery may be an effective treatment for breast cancer. PURPOSE: This randomized clinical trial is studying how well giving fulvestrant or tamoxifen works in treating postmenopausal women who are undergoing surgery for ductal carcinoma in situ of the breast.
This study will examine, for the first time, the independent contribution of a patient's own genetic makeup to the development of post-radiation complications, permitting the future development of predictive tests to avoid radiation injury. To do this, the investigators will examine gene markers in a series of breast, prostate, brain and lung cancer survivors who have received conformal radiotherapy between 1996 and 2003 at the Cross Cancer Institute and Tom Baker Cancer Centre.
RATIONALE: Chemoprevention is the use of certain drugs or supplements to keep cancer from forming, growing, or coming back. The use of omega-3 fatty acids may prevent breast cancer. PURPOSE: This randomized clinical trial is studying how well omega-3 fatty acids work in preventing breast cancer in women at high risk of developing breast cancer.
The purpose of this study is to evaluate the efficacy of a new dose of 500 mg Fulvestrant with the standard dose of 250 mg in postmenopausal women with oestrogen receptor positive advanced breast cancer who have failed on a previous endocrine treatment.
