Filter by:The primary purpose of our study is to evaluate whether gemcitabine as a single agent is superior to observation in improving progression-free survival (PFS) in patients with metastatic breast cancer (MBC) who achieved disease control with an initial six cycles of PG as their first-line treatment
The goal of this clinical research study is to learn if the study drug, alisertib, in combination with chemotherapy (paclitaxel), can shrink or slow tumor growth in women with hormone receptor (HR)-positive, HER2-negative or HR-negative, HER2-negative (triple negative) locally recurrent or metastatic breast cancer. The safety of alisertib in combination with paclitaxel will also be studied. The physical state of the patient, symptoms, changes in the size of the tumor, and laboratory findings obtained while on-study will help the research team decide if alisertib plus paclitaxel is safe and effective in patients with this type of breast cancer. Alisertib belongs to a group of drugs called Aurora kinase inhibitors. Alisertib blocks the activity of Aurora A kinase, a protein that is involved in tumor cell multiplication and survival. Aurora A kinase is expressed at higher than normal levels in many types of cancer, including breast cancer, and preclinical studies suggest that blocking the activity of this protein can lead to the death of cancer cells. Paclitaxel is a chemotherapy drug commonly used to treat many different kinds of cancer, including metastatic breast cancer. The reason to combine alisertib and paclitaxel is that in cancer therapy, combinations of drugs are often more effective as a treatment than either of the same drugs used alone.
The current study will compare PK, efficacy, safety, and immunogenicity of PF-05280014 (Trastuzumab-Pfizer) in combination with Taxotere® and Carboplatin (Paraplatin) versus Herceptin® (Trastuzumab-EU) approved in the EU in combination with Taxotere® and Carboplatin (Paraplatin) in patients with operable HER2 positive, breast cancer in the neoadjuvant setting. The hypothesis to be tested in this study is the percentage of patients with steady state Cycle 5 Ctrough (Cycle 6 pre-dose) >20 µg/mL of trastuzumab-Pfizer is similar to EU-approved trastuzumab, using a margin of -12.5%.
Rationale: In breast cancer (BC) patients, lymph node status is a key prognostic indicator. At present, axillary ultrasound (US) with subsequent fine needle aspiration cytology (FNAC) of suspicious lymph nodes (US+FNAC) is widely used as a pre-operative staging method. When US+FNAC is negative, a sentinel node procedure (SNP) is performed during breast surgery. Nowadays, an axillary lymph node dissection (ALND) is generally performed if one of the abovementioned diagnostic entities reveals lymph node metastases. However, the extensive role of ALND in BC patients with lymph node metastases may change or diminish in upcoming years due to emerging evidence that completion ALND (cALND) does not affect disease-free survival and overall survival in early BC patients with (sentinel) node-positive disease. Whether ALND is needed in these patients, should be based on (axillary) tumour load. Because of the fact that tumour load can only be reliably evaluated by SNP and not by US+FNAC, the role of SNP might become even more important in upcoming years. Ideally, the status of this sentinel lymph node is known prior to breast surgery, so a patient tailored treatment plan can be made and discussed with the patient before breast surgery. In this context, it would be very logical to perform a SNP under local anaesthesia (LA), prior to breast surgery. This might not only lead to significantly less two-step surgical procedures under general anaesthesia (GA), but might also lead to a reduction of depressive symptoms and anxiety and improved quality of life (QoL) of BC patients, because BC patients are in particular risk for psychological distress in the first three months after diagnosis of BC. Knowing lymph node status and the complete treatment plan as soon as possible (by performing a SNP under LA), might reduce this psychological distress. To investigate which BC patients would benefit most from SNP under LA, the investigators recently analysed 1132 BC patients retrospectively. Both prevalence of axillary lymph node metastases and prevalence of false negative results of US+FNAC were directly associated with age <60 years and with primary breast tumour size >20 mm. Hence, these BC patients might benefit most from SNP under LA. In the present study, the value of SNP under LA in these BC patients (i.e. <60 years with a breast carcinoma >20 mm) will be analysed. Objectives: Reduction of the mean number of operations under general anaesthesia per patient. Improvement of QoL. Reduction of depressive symptoms and experienced anxiety. Study design: Prospective single centre randomised controlled clinical trial. Study population: Women aged 18 to 60 years who are diagnosed with BC AND with a tumour size of >20 mm ultrasonographically AND with a negative or inconclusive pre-operative US+FNAC. Intervention: Sentinel Node Procedure under Local Anaesthesia (SNP under LA) Control: Traditional Sentinel Node Procedure under General Anaesthesia (SNP under GA) Main study parameters: Primary outcome parameters are the number of operations under GA per patient and the number of operations under LA per patient. Secondary outcome parameters are QoL, experienced depressive symptoms and anxiety. Timeline and statistics: The inclusion period will be conducted from the 1st of July 2014 to the 1st of August 2015, and 80 patients will be enrolled in this study (alpha 0.05; power 0.8). Inclusion of 80 patients will be sufficient to reduce the number of two-stage surgical procedures under general anaesthesia with 30%. Data will be analysed using descriptive statistics, Chi-squared test, Fisher's exact test, Mann-Whitney U test, Kruskall-Wallis test, students t-test, ANOVA, paired t-test, Wilcoxon signed-rank test, Friedman test, Pearson's and Spearman's rank correlation coefficients and finally logistic and linear regression analysis.
Lymphedema (significant arm swelling on the surgical side) is one of the most common complications following treatment for breast cancer. The impact of lymphedema is profound, resulting in negative self image, increased anxiety and poorer quality of life. In time, lymphedema can result in recurrent infections in the arm, functional impairment and pain. Approximately 21% of women who undergo breast cancer treatment develop lymphedema. Unfortunately this is a life-time condition which tends to worsen over time. Currently, treatment consists of intensive physiotherapy, meant to reduce the arm volume followed by the wearing of compression sleeves during the day for maintenance. This study hopes to show that the addition of night-time compression creates a measurable reduction in arm volume and that adding night-time compression to the standard care (daytime compression only) will produce improvements in quality of life for breast cancer survivors.
This pilot clinical trial studies intensity-modulated accelerated partial breast irradiation (APBI) before surgery in treating older patients with estrogen receptor positive or progesterone receptor positive stage I breast cancer. APBI is a specialized type of radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
Background: Several clinical trials are underway to investigate if variable forms of vitamin D (D2 vs. D3) prescribed at different doses (10,000-50,000 IUs/week) can improve the side-effects associated with treatment for estrogen receptor positive (ER+) breast cancer, specifically aromatase inhibitors (AIs.) Presumably for generalizability and potential safety purposes, these trials predominantly exclude women with metastatic breast cancer (MBC); a rapidly expanding sector of the cancer survivor population who experience significant treatment-related side-effects. Evaluation of the safety of vitamin D3 supplementation is crucial since supplementation can lead to high calcium and importantly, in lab studies have shown that vitamin D3 affects a gene that increases estrogen production. To assure that vitamin D3 does not affect the clinical effects of anti-estrogen therapies, the effect of vitamin D3 supplements on estrogen production requires an evaluation that further explores and defines its potential role in symptom management for this population. Objectives: This pilot study will evaluate the feasibility of vitamin D3 supplementation in women with MBC, providing much needed data on the preliminary safety and efficacy of this treatment in this patient population. This study will determine: 1) if weekly supplementation of high dose vitamin D3 increases serum vitamin D levels without adverse effects related to such therapy (primary aim); 2) the effects of vitamin D3 supplementation on symptom management (secondary aim); and 3) if vitamin D3 supplementation is associated with improved inflammation (exploratory aim.) Methods: This is an 8 week "proof of concept" study to monitor laboratory parameters and to assess potential effects on short-term outcomes. Adult, female patients (>=18 years) with ER+ MBC (Stage IV) of any race/ethnicity and a history of vitamin D < 30 mg/dl will be recruited from within and around LUMC. Following current clinical practice guidelines, eligible participants will receive 50,000 IUs of vitamin D3 weekly for 8 weeks. Laboratory values, muscle function and inflammation will be examined pre- and post-supplementation, while symptoms will be assessed at baseline, 4 and 8 weeks post-supplementation. We will assess if increases in vitamin D are associated with clinically significant improvements in symptoms and QOL, and decreased inflammation.
The primary objective of A-PLUS trial is to evaluate and compare the efficacy of induction BEEP (bevacizumab preconditioning followed by etoposide and cisplatin) followed by whole bran radiotherapy (WBRT) with WBRT alone in the controlling of brain metastases (BM) in metastatic breast cancer (MBC) patients who have not previously received WBRT. In past 2 years, the research team has demonstrated that BEEP regimen is a highly effective treatment for brain metastases of breast cancer progressing from WBRT by a multi-center phase II study (ClinicalTrials.gov Identifier: NCT01281696). The basic concept of preconditioning, as referred to starting bevacizumab 1 day before chemotherapy, is that the effect of bevacizumab induced tumor vascular normalization takes time to mature. The investigators hypothesized that as induction BEEP decreased the size of brain tumors, the effectiveness of WBRT would be maximized. The investigators expect this integrated approach will do greater benefit to MBC patients with BM, irrespective of subtype.
Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
This is an open-label, multicenter, 2x2 factorial design, randomized controlled, Phase III study comparing the disease free survival after randomisation in patients treated with 3 cycles of Epirubicin-Fluorouracil-Cyclophosphamide(FEC)-chemotherapy, followed by 3 cycles of Docetaxel(Doc)-chemotherapy versus 3 cycles of Epirubicin-Fluorouracil-Cyclophosphamide(FEC), followed by 3 cycles of Gemcitabine-Docetaxel(DocGemzar)-chemotherapy, and to compare the disease free survival after randomisation in patients treated with 2 years of Zoledronate versus 5 years of Zoledronate in patients with early primary breast cancer. Patients will be required to have histopathological proof of axillary lymph node metastases (pN1-3) or high risk node negative, defined as: 'pT≥2 or histopathological grade 3, or age ≤ 35 or negative hormone receptor', but are not allowed to have evidence of distant disease. Patients will have to be entered into the study no later than 6 weeks after complete resection of the primary tumor. No other antineoplastic treatment other than surgical treatment, the defined cytotoxic and endocrine treatment and radiotherapy will be allowed prior to study entry and during the course of the study. After surgery, leading to R0 resection of the invasive and intraductal components of the primary tumor, patients will be randomized to one of the following treatments: First randomization AA: 3 cycles of 5-Fluorouracil 500 mg/m² i.v. body surface area and Epirubicin 100 mg/m² i.v. and Cyclophosphamide 500 mg/m² i.v., (FEC100), each administered on day 1, repeated on day 22, subsequently followed by 3 cycles of Docetaxel 75 mg/m² body surface area i.v. (Doc), and Gemcitabine 1000 mg/m² i.v. (30 min infusion) (Gemzar), administered on day 1, followed by Gemcitabine 1000 mg/m² i.v. (30 min infusion) on day 8, repeated on day 22 AB: 3 cycles of 5-Fluorouracil 500 mg/m² i.v. body surface area and Epirubicin 100 mg/m² i.v. and Cyclophosphamide 500 mg/m² i.v., (FEC100), each administered on day 1, repeated on day 22, subsequently followed by 3 cycles of Docetaxel 100 mg/m² body surface area i.v. (Doc), administered on day 1, repeated on day 22 Second randomization B BA: Zoledronic acid 4 mg i.v., every 3 months for the duration of two years, subsequently followed by zoledronic acid 4 mg i.v., every 6 months for the duration of additional three years BB: Zoledronic acid 4 mg i.v., every 3 months for the duration of two years During the zoledronic acid treatment period, patients will receive 500 mg Calcium p.o. qid and 400 i.E. Vitamin D p.o. qid. Patients with positive hormone receptor status (≥ 10 % positively stained cells for estrogen and/or progesterone) of the primary tumor will receive Tamoxifen treatment 20 mg p.o. per day for 2 years, after the end of chemotherapy. Subsequent to chemotherapy, postmenopausal patients with positive hormone receptor status will be treated with Anastrozole (Arimidex®) 1 mg p.o. for additional 3 years, premenopausal patients will continue Tamoxifen treatment for additional 3 years. In addition to tamoxifen, all patients with positive hormone receptor status of the primary tumor and under the age of 40 or restart of menstrual bleeding within 6 months after the completion of cytostatic treatment or with premenopausal hormone levels as defined below will receive Goserelin (Zoladex®) 3.6 mg subcutaneously every 4 weeks over a period of 2 years following chemotherapy. Premenopausal endocrine status will be assumed, if the following serum levels are met: Luteinizing hormone (LH) < 20 mIE/ml, follicle stimulating hormone (FSH) < 20 mIE/ml and estradiol (E2) > 20 pg/ml. Endocrine therapy will start after the end of chemotherapy. All patients with breast conserving therapy or more than 3 axillary lymph node metastases or in the following cases after mastectomy: - T3/T4-carcinoma - T2-carcinoma > 3 cm - multicentric tumor growth - lymphangiosis carcinomatosa or vessel involvement - involvement of the pectoralis fascia or a safety margin < 5 mm. will receive adjuvant radiotherapy.
