Filter by:This phase II trial is studying how well MD2206 works in treating patients with advanced refractory biliary cancer that cannot be removed by 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.
Hypofractionated intraoperative boost (HIOB) is defined as hypofractionated WBRT (40.5 Gy in 2.7 Gy per fraction) preceded by an intraoperative boost to the tumor bed (10 Gy IOERT). The HIOB study concept will test whether such a combined schedule is superior or iso-effective standard RT in terms of local control and cosmetic outcome.
This randomized phase III clinical trial studies how well tamoxifen citrate, anastrozole, letrozole, or exemestane with or without chemotherapy work in treating patients with breast cancer that has spread from where it began in the breast to surrounding normal tissue (invasive). Estrogen can cause the growth of breast cancer cells. Hormone therapy, using tamoxifen citrate, may fight breast cancer by blocking the use of estrogen by the tumor cells. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, may fight breast cancer by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving tamoxifen citrate, anastrozole, letrozole, or exemestane is more effective with combination chemotherapy in treating patients with breast cancer.
The purpose of this research study is to see if a participant's nipple and areola can be safely preserved by adding radiation to these areas after a nipple-sparing mastectomy and immediate breast reconstruction.
RATIONALE: Zoledronic acid may prevent bone loss and help prevent or lessen musculoskeletal symptoms in women receiving hormone therapy for breast cancer. PURPOSE: This phase II trial is studying how well zoledronic acid works in preventing musculoskeletal symptoms in post-menopausal women with stage I, stage II, or stage III breast cancer receiving letrozole.
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 evaluate the diagnostic performance of MRI±biopsy to optimize resection of Ductal Carcinoma In Situ (DCIS) breast cancer.
This phase II trial is studying how well giving sorafenib tosylate together with erlotinib hydrochloride works in treating patients with locally advanced, unresectable, or metastatic gallbladder cancer or cholangiocarcinoma. Sorafenib tosylate and erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth or by blocking blood flow to the tumor.
