Active clinical trials for "Breast Neoplasms"

The study will determine the sensitivity, specificity, negative predictive value and positive predictive value of the OSNA Breast Cancer System for patients receiving Sentinel Lymph Node biopsies after receiving neoadjuvant hormonal/chemotherapy as compared to permanent section Hematoxylin and Eosin (H&E) and Immuno-histochemistry (IHC) staining.

This study is a multicenter, randomized study, open-label, phase III study.The efficacy of irinotecan and capecitabine combination will be superior to capecitabine alone in term of progression free survival in metastatic breast cancer patients previously treated with anthracycline and taxane.

The current study is a multicentre, randomized, open (unblended), prospective clinical trial which is sponsored by the researchers. The trial is designed to compare the effectiveness between docetaxel plus epirubicin, and docetaxel plus epirubicin plus cyclophosphamide as neoadjuvant chemotherapy for operable premenopausal breast cancer patients, and also to compare the outcomes associated with chemo-induced amenorrhea between the two neoadjuvant chemotherapies. The investigators will randomly assign 600 premenopausal female patients with operable breast cancer to receive four cycles of docetaxel and epirubicin (TE); or four cycles of docetaxel, epirubicin, and cyclophosphamide (TEC). After every two cycles of neoadjuvant chemotherapy, the investigators will estimate the effectiveness of therapy. Patients will undergo modified radical mastectomy or breast-conserving surgery after four cycles of neoadjuvant chemotherapy, and then receive postoperative chemotherapy (two cycles), radiation therapy, herceptin targeted therapy or hormone therapy according to the NCCN (2011) guideline. The follow-up will be ten years after surgeries. The primary aim is to examine whether the docetaxel and epirubicin (TE) will be as effective as the docetaxel, epirubicin, and cyclophosphamide (TEC) (pCR rate, cCR rate, PR rate, SD rate, progression-free survival (PFS) and overall survival (OS)). The secondary aim is to correlate chemo (TE/TEC)-induced amenorrhea with outcomes in premenopausal women.

Background: Recent single arm studies have suggested that partial breast irradiation (PBI), delivered in a relatively short overall treatment time of a few days, may be an effective alternative to adjuvant whole breast irradiation (WBI) delivered over a number of weeks. Several PBI modalities and techniques have been investigated, including interstitial brachytherapy and external beam radiation therapy, most often given over the course of one week of twice daily outpatient treatments. One randomized study has shown equivalency between WBI and PBI using brachytherapy. There are currently three large phase-III randomized studies comparing PBI to WBI. Permanent Breast Seed Implant (PBSI) is the newest PBI technique which has been piloted at the Odette Cancer Centre (OCC) in Toronto. The main advantage of this technique is that it requires only one out-patient procedure. The treatment is administered by implanting radioactive Palladium (103Pd) seeds into the tumor bed region in a 1 to ½ hour outpatient procedure, after which the patient is discharged home to resume her normal living activities. This PBI procedure was shown to be well tolerated with minimal acute toxicity. Estimated partner radiation exposure was well within internationally acceptable levels. Subjects with a seroma >2cm were, however, excluded. Hypothesis: PBSI is a feasible, safe, and acceptable treatment option for the subject and her partner in the context of medical practice and resources in BC. Objectives: In subjects who have undergone breast conserving surgery for early breast cancer: To determine the technical feasibility of PBSI in BC To measure the subject's partner in terms of radiation protection To evaluate acceptability of PBSI by the subject To assess resource requirements for PBSI Method: This is a single arm feasibility study. Five women who had undergone breast conserving surgery for breast cancer with low risk of local recurrence will be accrued. This study will adhere to a detailed written protocol for radiation measurements and protection. Subjects will undergo PBSI within 4-14 weeks from last breast surgery. The procedure will be performed in an outpatient setting, under conscious sedation and local anesthesia, by a team with a wide brachytherapy experience. The technique used in this feasibility study will be based on the OCC technique. It is intended that two oncologists and one physicist will spend 2-3 days at the OCC to acquire detailed and firsthand knowledge of the technique as implemented at that centre. The OCC technique is US-based; in this study, however, an additional CT-assisted planning component will be investigated building on the experience of the VIC team which conducted the BC Cancer Agency Vancouver Island Centre's pilot study of CT-based multi-catheter brachytherapy PBI. Systemic therapy will be according to BCCA guidelines; however, subjects requiring adjuvant chemotherapy will be excluded from this study. Subjects will be followed prospectively for 5 years for evaluation of toxicity, QOL and cosmesis. Disease status will be recorded. Relevance: Completing adjuvant breast irradiation with a single out-patient treatment could significantly improve QOL and convenience for patients choosing breast conserving therapy. Confirming the technical feasibility and safety of PBSI is needed before progressing to larger prospective evaluation of this novel adjuvant radiation therapy technique as a viable treatment option for women in British Columbia.

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy, such as intensity-modulated radiation therapy, that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. It is not yet known which radiation therapy schedule is more effective in treating breast cancer. PURPOSE: This randomized phase III trial is studying three different radiation therapy schedules to compare how well they work in treating women who have undergone breast conservation surgery and systemic therapy for early breast cancer.

RATIONALE: Diagnostic procedures that measure biomarker levels in nipple section and blood samples, may help in the early detection of breast cancer. PURPOSE: This clinical trial is studying nipple secretion samples in detecting breast cancer in patients and healthy participants undergoing breast cancer screening, breast diagnostic studies, or treatment for benign breast disease.

Purpose: To determine whether [18F]FES can predict clinical benefit (defined as complete response, partial response and stable disease ≥ 6 months) to fulvestrant (250 mg IM q 28 days) in post-menopausal women with recurrent or metastatic ER+ breast cancer who are candidates for further hormonal therapy.

RATIONALE: A breath test that measures enzymes may be effective in identifying women in whom tamoxifen may not be effective. PURPOSE: This clinical trial is studying a breath test to see how well it works in women receiving tamoxifen for the prevention or treatment of breast cancer.

RATIONALE: Estrogen can promote growth of endocrine sensitive breast cancer cells. Endocrine therapy with tamoxifen citrate may fight breast cancer by blocking the use of estrogen by the tumor cells. Pharmacokinetics and -genomics can have an impact on the efficacy of the treatment. PURPOSE: This phase III trial is studying blood samples to see if the level of active metabolites of tamoxifen can be improved in patients with breast cancer.

RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about nausea and vomiting caused by cancer treatment. PURPOSE: This laboratory study is looking at blood samples from patients with cancer who were treated on a clinical trial to control nausea and vomiting during donor stem cell transplant.
