Filter by:Naltrexone is a drug which blocks some effects of chemicals called beta-endorphins that are made in the body. Beta-endorphins can be made in response to stress, injury, and also pleasurable activities. In previous studies, it has been shown that levels of beta-endorphins in the blood go up during radiation therapy, and that this increase is linked to fatigue. This suggests that naltrexone may help to reduce fatigue in people who are getting radiation therapy In this research study, the investigators are looking to see whether naltrexone works better than a placebo in reducing fatigue during radiation therapy.
The purpose of this study is to examine the genetic material called microRNA of three types of specimens from women with breast cancer. The study also seeks to examine the effectiveness of using a new agent called oxytocin to increase the amount of nipple fluid that can be collected during surgery.
This is a pilot study designed to investigate new techniques to guide the appropriate diagnosis and treatment of Ductal Carcinoma In-situ (DCIS). The microvascularity and stiffness of the lesion may be prognostic factors that can guide the need for more or less extensive therapy or perhaps only imaging follow-up may be needed.
This will be a proof of principle clinical trial to evaluate the use of pasireotide (SOM230) in women with ductal carcinoma in situ (DCIS) of the breast. Surgery and radiotherapy are used as treatment for DCIS and subsequent treatment with antiestrogens has been effective in reducing the occurrence of invasive breast cancer. Unfortunately, treatment with antiestrogens carries potential serious side effects and toxicities that are intolerable to some patients. Preliminary data suggest that inhibition of IGF-1 action in the breast will be at least as effective as tamoxifen. Pasireotide is a somatostatin analog that prevents mammary development by inhibiting IGF-1 action directly in the mammary gland and also indirectly without causing menopausal symptoms. This study is an expansion of work that we have previously done in women with atypical hyperplasia of the breast, which showed that treatment with pasireotide for 10 days caused a reduction in the cellularity of these precancerous lesions. In our present study, women with DCIS will be treated with pasireotide for 20 days prior to surgical excision. Endpoints will be as follows: 1. To determine whether pasireotide will inhibit cell proliferation and angiogenesis (signs of tumor growth), and stimulate apoptosis (cell death) in surgically excised tissue in comparison to core biopsies from women with estrogen receptor (ER) positive DCIS. Both the core biopsy and surgical excision are standard of care procedures that women with DCIS have regardless of participation in this trial. 2. To use dynamic contrast enhanced MRI to assess patients before and after treatment with pasireotide and evaluate for changes in tumor volume and other tumor related features 3. In our previous study we found that many women experienced a slight elevation in blood sugar with 10 days of treatment with pasireotide. Other work has shown that this effect often resolves with greater duration of treatment. We are therefore expanding the duration of treatment in this study to 20 days to assess if the initial hyperglycemia seen with pasireotide improves as treatment duration progresses.
The primary objective of this study is to identify the group of women with early stage breast cancer most likely to benefit from treatment with the selective progesterone receptor modulator (SPRM) mifepristone. This will be done by treating women briefly prior to planned surgery and examining the decrease in growth rate (measured by Ki-67 immunohistochemistry) in tumor samples taken before and after exposure to mifepristone.
The purpose of this study is to find molecular signs (biomarkers) to better understand the role of green tea as an anti-cancer and anti-inflammation agent in women with newly-diagnosed ductal carcinoma in situ (DCIS).
The purpose of this study is to establish the utility of lapatinib in the treatment of DCIS, particularly ER-negative DCIS.
