Filter by:This phase II trial studies how well radiation therapy works in treating post-menopausal women with early stage breast cancer undergoing surgery. Radiation therapy uses high energy x rays to kill tumor cells. This may be an effective treatment for breast cancer.
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.
To determine whether biomarkers assessed in blood samples can be used to detect individuals at risk for developing blood clots or worsening of their underlying disease. The ultimate goal of the study is to identify key biomarkers derived from blood that are most characteristic and informative of individuals who will go on to develop a clotting complication.
We hypothesize that the combination of mammography and CE-MRI will improve the surgeon and radiologist's ability to define extent of disease prior to surgical resection, improve the odds of obtaining clear surgical margins, and increase the efficacy of IORT delivered immediately after initial surgical resection. In this investigation, we will determine whether or not patients deemed eligible for 'immediate" IORT based on mammography and CE-MRI can be successfully treated without the need for re-excision or additional radiotherapy due to inadequate surgical margins.
Primary: To determine the pathological remission following the chemotherapy combination docetaxel and doxorubicin in large breast cancer Secondary: - Clinical response rate - To investigate the safety of docetaxel doxorubicin combination in the treatment for neoadjuvant chemotherapy of breast cancer - Type of surgery (radical/conservative)
RATIONALE: Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving internal radiation therapy using a special radiation therapy device may kill any tumor cells that remain after surgery. PURPOSE: This phase II trial is studying how well internal radiation therapy after lumpectomy works in treating women with ductal carcinoma in situ.
