Filter by:Some tumors use estrogen in the body to assist with growth. Letrozole is a drug that is prevents cells from producing estrogens. This should assist with the slowing of growth of tumor cells. Letrozole also promotes cell destruction by inhibiting a cellular destruction pathway. The objectives of this study will look at the differences between the cellular destruction pathway before and after letrozole use, and the differences in the cellular destruction pathway in participants that have received letrozole versus those who did not. The study will also look at a gene in all participants called Ki67. This gene is associated with the rate of tumor cell growth. The study will measure the levels of Ki67 and compare them to the amount of activation of the cellular destruction pathway. Participants in this study will have undergone a diagnostic biopsy of their breast tissue. In order to meet these objectives, one group of participants (Arm A) will not receive letrozole. Tissue leftover from their diagnostic biopsy will be treated with everolimus (RAD001) in the laboratory and the effects of this drug on the cellular destruction pathway will be studied. The other group of participants (Arm B) will take letrozole for a minimum of 10 and maximum of 21 days. They will have a second tumor sample taken as part of their surgical procedure completed to remove the tumor tissue. Any differences in the cellular destruction pathway before and after exposure to letrozole will be measured.
¡Fortaleza Latina! is a multi-level randomized trial to increase participation in mammography screening among Latinas who seek care at a community health center in Western Washington. In partnership with the partnering community health center, we have obtained lists of women patients aged 42 to 74 years old who had not had a mammogram in the last two years and resided within defined radii of the four clinics. Baseline and one year follow-up surveys will be obtained by in person home interview. Participants are randomized within clinic to intervention or comparison group. The intervention consist of two motivational interviewing sessions, one in person in the home, and one telephone follow-up. The study hypothesis is that a higher proportion of participants in the motivational interviewing arm will obtain a screening mammogram within the study period than those in the comparison arm.
This is a Phase II study trying to identify whether short term treatment with PD0332991 yields anti-proliferative response -defined by a low level of Ki67 expression (IHC) at surgery- or induces senescence as determined by SABG expression (IHC) in tumors from patients with early breast cancer non-candidates for neoadjuvant hormonotherapy or chemotherapy, as compared to no treatment.
- This is a phase II, prospective, single-center, non-randomized, non-controlled study. - Sentinel lymph node biopsy (SNB) is a standard staging procedure in early breast cancer. The potentially increasing false negative rate of SNB was concerned if the sonographic abnormal node was not excised. The aim of this study was to evaluate the accuracy of SNB in breast cancer with sonographic abnormal axillary lymph nodes.
The purpose of the this study is to investigate the anti-tumor activity and tolerability of the study medications Degarelix and Triptorelin in premenopausal women receiving preoperative treatment with Letrozole.
Serious concern about the role of anesthesia in tumor recurrence has considerably risen over years, but the lack of surrogate markers for tumor spreading made trials addressing this issue difficult to realize. In breast cancer patients CTC positivity has been recently recognized as an independent prognostic factor. In this respect, we postulated that in a first step changes in the number of CTC after general anesthesia would help to determine the effect of anesthesia on this tumor marker.
This study will evaluate the effect of Avastin (15mg/kg iv) in combination with Docetaxel and Xeloda, given as pre-operative therapy to patients with primary breast cancer. Avastin will be administered every 3 weeks, for the first 5 cycles of chemotherapy. The anticipated time on study treatment is 3-12 months.
Breast neoplasm is the second most common type in the world. Radiation therapy is a key component in the treatment of breast cancer. Acute skin reaction is one of the most common side effects of radiation therapy. Several studies were performed for prophylaxis of this adverse event, however, until this moment there is no consensus for clinical practice . Second meta-analysis , the ideal candidate for the radiodermatitis prevention would be an agent capable of repairing damage to DNA or agents that promote cell proliferation . The low power laser promotes tissue repair ( reduces inflammatory phase and induces collagen synthesis ) . Its use in the treatment of adverse events of cancer treatment is well established in two situations : in the prophylaxis and treatment of mucositis and in the treatment of lymphedema . The purpose of this study is to use the low power laser in patients with breast cancer undergoing radiotherapy treatment to evaluate the effects of Laser InGaAIP 660Nm in preventing radiodermatitis.
This randomized phase II trial studies how well brief behavioral therapy works in improving sleep disorders in patients with stage I-III breast cancer undergoing chemotherapy. Sleep disorder counseling may reduce fatigue and insomnia as well as improve the well-being and quality of life in patients with breast cancer who are undergoing chemotherapy.
This is a phase I study to evaluate the safety and define the pharmacokinetic (PK) profile of orally administered reparixin in combination with paclitaxel in HER 2 (Human epidermal growth factor receptor-2) negative metastatic breast cancer patients. The primary objective of this study was to evaluate the safety and define the pharmacokinetic (PK) profile of orally administered reparixin in combination with paclitaxel in HER-2 negative MBC patients. The secondary objectives were to: 1. Evaluate the effects of orally administered reparixin on cancer stem cell (CSC) markers, the tumoral microenvironment and markers of cytokine inflammation; 2. Evaluate peripheral blood samples for enumeration of circulating tumor cells (CTCs), molecular characterization as CSCs and perform epithelial-mesenchymal transition (EMT) biomarker profiling; 3. Assess disease response for indication of efficacy.
