The investigators' hypothesis is that valproic acid given before surgery for newly diagnosed breast cancer will increase breast tumor histone acetylation at tolerable doses and that the increase in breast tumor histone acetylation will correlate with valproic acid blood levels and changes in peripheral blood white blood cell histone acetylation. Published in vitro studies have shown sensitivity of breast cancer cells to histone deacetylase inhibitors (Fortunati et al., 2008; Fuino et al., 2003; Hodges-Gallagher et al., 2007; Olsen et al., 2004). The investigators' gene array data predict sensitivity to valproic acid in over half of breast cancers [Bild, unpublished]. The investigators hypothesize that in women with newly diagnosed breast cancers valproic acid will have an unacceptable toxicity rate less than 15% at doses that increase tumor histone acetylation and that valproic acid will decrease the Ki-67 in at least half of breast tumors by over 20%. The investigators also hypothesize that their genomically-derived signature for sensitivity to valproic acid (GDSS-VPA) can be used to predict which tumors will have a decrease proliferation as measured by Ki-67 by at least 20%. The investigators hypothesize that valproic acid levels and histone acetylation levels in peripheral leukocytes will correlate with a decrease in the Ki-67 proliferation index by 20%. The investigators hypothesize that DCE-MRI imaging studies will provide an accurate and quantitative means of assessing tumor response to valproic acid. Finally, the investigators hypothesize that response to valproic acid will not be affected by intrinsic breast cancer subtype.
The proposed project will document the degree of function decline, assess the relationship between function and cancer- related symptoms and evaluate relationships between function and quality of life. Participants are evaluated before therapy, after therapy and again 3 months post therapy to evaluate functional change. Knowledge gained will help us plan interventions around the time of cancer therapy to help older adults preserve or improve function.
This phase 2, multicenter, randomized, open-label, comparative study was designed to determine the effect of darbepoetin alfa on hospital days, economic outcomes, and health related quality of life (HRQOL) in anemic patients with nonmyeloid malignancies who were not receiving chemotherapy. Participants were randomly assigned in a 4:1 allocation ratio to receive either 21 weeks of darbepoetin alfa treatment (treatment group) or 12 weeks of observation followed by up to 9 weeks of darbepoetin alfa treatment (observation group).
OBJECTIVES: This study proposes to evaluate the feasibility of delivery of this treatment in terms of toxicity. If toxicity is not acceptable, the treatment is not feasible. Primary Objectives - To establish a preliminary assessment whether toxicity rates are acceptable in patients with locally advanced intra or extrahepatic cholangiocarcinoma when treated with a regimen of gemcitabine every two weeks and continuous fluorouracil (5-FU) given concurrently with external beam radiation therapy to a total dose of 45 gray(Gy), followed by a brachytherapy or Stereotactic Body Radiation Therapy(SBRT) boost. Secondary Objectives - To evaluate the overall survival rate, progression free survival rate, tumor response rate, local control rate and the rate of distant metastases following gemcitabine and continuous 5-FU concurrent with radiation therapy in patients with locally advanced intra or extrahepatic cholangiocarcinoma. - To evaluate the rate at which patients with unresectable extrahepatic cholangiocarcinoma become resectable following gemcitabine and radiation therapy.
OBJECTIVES - Primary: To evaluate the bone anabolic effect of bortezomib in patients with smoldering myeloma. - Secondary: To evaluate the effect of bortezomib on the natural history of smoldering myeloma.
In this study the investigators will determine the safety and effectiveness of Tinzaparin in preventing blood clots for up to 12 months of treatment.
This study is primarily designed to assess the safety and tolerability of AZD4547 at increasing doses in patients with advanced solid malignancies and for whom no standard medication options are available. It also assesses the blood levels and action of AZD4547 in the body over a period of time.
This was a randomized, open-label, multi-center Phase III study evaluating the efficacy and safety of lapatinib in combination with trastuzumab versus trastuzumab alone as continued HER2 suppression therapy in women with HER2-positive metastatic breast cancer (MBC). Eligible subjects should have completed 12 to 24 weeks of first- or second-line treatment with trastuzumab plus chemotherapy, experienced either complete disappearance of all metastatic lesions, or persistence of metastatic disease (stable disease) without unequivocal progression or the occurrence of new lesions, and been indicated to continue to receive trastuzumab alone as maintenance therapy. Eligible subjects who entered the LPT112515 study on first-line treatment should not have known history of central nervous system (CNS) metastases; subjects who entered the study on second-line treatment should not have known history of CNS metastases or have stable (asymptomatic and off steroids ≥3 months) CNS metastases. The primary objective of this study was to compare progression-free survival (PFS) in subjects with HER2-positive MBC randomized to receive treatment with lapatinib plus trastuzumab versus those randomized to receive trastuzumab alone. The secondary objectives included overall survival, clinical benefit response rate (CR, PR or SD ≥24 weeks) and the qualitative and quantitative adverse event profile of the 2 treatment arms. It was estimated that 280 subjects (140 per group) would be required to observe 193 PFS events.
RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to chronic graft-versus-host disease in patients who have undergone donor stem cell transplant. PURPOSE: This phase I trial is studying chronic graft-versus-host disease in patients who have undergone donor stem cell transplant.
