Active clinical trials for "Breast Neoplasms"

The purpose of this study is: To evaluate the hypothesis: Can PEM Flex Solo II PET scanner ascertain response to neoadjuvant chemotherapy in patients with breast cancer? To compare the results from the PEM Flex Solo II PET scanner to the standard of care bilateral breast MRI.

The purpose of the study is to assess the benefit of panobinostat monotherapy given either orally or i.v. to women with HER2-positive locally recurrent or metastatic breast cancer

Women with breast cancer who are not eligible for breast conserving surgery or who have node-involvement are sometimes treated with chemotherapy up front, in hopes of allowing for a woman to keep her breast and decreasing the size of the excision for her breast cancer. While current research has shown that survival is the same whether women are treated with chemotherapy first or surgery first for breast cancer, the investigators do not yet know how to treat women with persistent breast cancer after she has received primary chemotherapy. This study looks at the use of a combination regimen of two agents (gemcitabine and capecitabine), both of which are active in breast cancer, and using Avastin to see if this regimen can be given to women treated with primary chemotherapy and then surgery, considered to be at high risk of relapse.

Women with early stage breast cancer may experience difficulty falling asleep or staying asleep. If this occurs for more than 4 weeks, these participants may have chronic insomnia. Chronic insomnia can lead to difficulty coping with stress, changes in mood, increased use of medications for sleep and an overall decrease in quality of life. The investigators have developed an internet-based website that is designed to help people manage symptoms typically experienced by breast cancer survivors, including insomnia, fatigue, pain and overall poor quality of life. The investigators want to learn whether this type of treatment can reduce chronic insomnia and improve the way subjects feel using both questionnaires and a special form of a wrist watch. This information may help the investigators better manage sleep difficulties in subjects who experience these symptoms after diagnosis of their breast cancer.

Hormonal therapy administered before surgery in ER-positive and HER2-positive patients with breast cancer.

The trial will utilize Nutraceuticals (Vitamin D 2000IU oral once daily, Vitamin B6 100 mg oral once daily, Vitamin B12 100 mcg oral once daily, Omega-3 Fatty Acids 900 mg oral three times a day) in patients treated with Docetacel as Neoadjuvant or Adjuvant Breast cancer Therapy. The trial is being conducted to see if the use of Nutraceuticals will prevent or reduce Chemotherapy Induced Peripheral Neuropathy (CIPN).

Pharmacokinetic, bioequivalence study

The course of the disease in female patients with metastatic mammary carcinoma can vary greatly. In this connection, the individual prognosis depends on a complex interaction of tumor- and patient-related factors. To take account of such differences, it is necessary to employ individual methods of treatment which are suited to the course of each patient's disease. Prof. Possinger and Dr. Schmid (Charite Berlin) and Prof. Wischnewsky (University of Bremen) have developed an approach that can help to achieve this goal with the aid of computerized machine learning techniques (MLT). The use of machine learning methods can be beneficial in oncology in two respects. On the one hand, an attempt can be made to individually estimate clinically relevant parameters like, for example, the recurrence probability or expected survival time as precisely as possible based on the established prognostic factors. And on the other hand, it may be possible with the aid of MLT to understand structural relationships between the clinical result and measured or established tumor-/patient-related variables. To analyze the possible benefits of machine learning techniques for patients with metastatic breast cancer, the aim of study FEM-D-2 is to investigate whether it is possible to characterize those patients who either do or do not respond to a specific treatment with a precision of 90%, prospectively estimate the time until worsening of the disease under a given treatment, and classify patients in groups with favorable and poor chances of medium-term survival. The use of inductive learning algorithms with machine learning also makes it possible to very accurately estimate the time until progression of the tumor growth. In patients who respond to letrozole therapy, the time until tumor progression depends on factors like pain, age, body mass index, disease-free interval, main localization of metastatic spread, and response to previous estrogen therapy. Only very minimal differences are found when comparing the actual time until progression of the disease and that calculated by the system (at least for survival times < 1 year). Furthermore, using machine learning techniques it has become possible to use initial data assessed before a letrozole treatment to estimate the survival time and distinguish patients with a high risk of dying soon from other patients with a more favorable prognosis.

Breast conservation therapy (BCT) is now widely accepted as a treatment option for most women with Stage I and II invasive breast cancer and most patients with ductal carcinoma in situ (DCIS). Despite superior cosmetic outcome, BCT is more complex and requires a protracted treatment regimen comprised of 6 weeks of daily external beam radiation therapy to the whole breast. The purpose of this study is to determine if an acceptable outcome can be achieved with radiation delivered only to the region of the tumor bed. If this is true, partial breast irradiation may lend itself to much shorter treatment times (one week) and the toxicities to adjacent normal structures (heart, lung, chest wall) will be greatly reduced.

To evaluate and compare the time to progression of the combination of capecitabine (825 mg/m2 twice daily) and docetaxel (75mg/m2 i.v.) to that of capecitabine (1000 mg/m2 twice daily) until progressive disease followed sequentially by docetaxel (75 mg/m2 i.v. D1 Q3W).
