Filter by:To explore the real world data of trastuzumab Combined With Trastuzumab And Chemotherapy in China, and to explore the relationship between progression free survival and treatment pattern.
A phase Ib study to investigate the safety, tolerability and trends of efficacy of ALECSAT treatment as an add-on therapy to carboplatin and gemcitabine in patients with locally advanced or metastatic triple-negative breast cancer.
The investigators propose to use clinically validated patient avatar technology ("PDXovo") that can test multiple drugs against patients' cancers to identify the most promising systemic therapy for each individual.
Background: Breast cancer is one of the most prevalent cancers worldwide. Fortunately, survival has improved in recent years thanks to its early detection and curative treatments such as mastectomy. However, this medical procedure is associated with a range of unwanted effects such as postoperative pain and anxiety. Some studies have reported that acupuncture could be an effective treatment to control these types of symptoms, although only few studies have been conducted on women undergoing mastectomy. Methods: This is a pragmatic randomized controlled trial with blind assessors. The study will be conducted in the Breast Unit of Hospital Universitario Sagrado Corazon of Barcelona (Spain). A sample of 40 women will be recruited and randomized to receive acupuncture treatment in addition to standard care procedures, or standard care procedures alone. The main outcome, pain, will be assessed after the surgical intervention and 4, 10 and 30 days later using the numerical rating scale. Secondary outcomes include anxiety, use of analgesics, nausea, adverse effects, and surgical complications. Discussion: Acupuncture is a low-cost non-pharmacological strategy. This study will help to clarify its possible role in controlling post-mastectomy adverse effects.
While the role of automated breast ultrasound (ABUS) as an alternative to hand-held ultrasound (HHUS) in breast cancer screening has been established, the use of ABUS in preoperative evaluation of newly diagnosed breast cancer patients is still limited. This may be because axillary areas are not included in the scanning area of ABUS. Newly diagnosed breast cancer patients have undergone axillary US to predict axillary lymph node metastasis before surgery, in combination with preoperative breast US, in many institutions. However, recent studies have reported that sentinel lymph node biopsy alone is sufficient for diagnosis and treatment of axillae of patients with early-stage breast cancer, because the incidence of axillary lymph node metastasis is very low. Therefore, the clinical significance of preoperative axillary US is being lowered in patients with early-stage breast cancers. Thus, considering that coronal images provided by ABUS may be more advantageous for detection of multifocal or multicentric cancer, we hypothesized that ABUS could replace HHUS in preoperative staging of patients with early-stage breast cancers (clinical Tis, T1-2/N0 cancers) for whom preoperative axillary US is not necessary. The purpose of this study was to prospectively compare the diagnostic performances of ABUS and HHUS in preoperative evaluation of patients with early-stage breast cancers. This study will be conducted with institutional review board approval, and written informed consent will be obtained. From the Jan 2019 to Dec 2021, 675 patients diagnosed with early-stage breast cancer will be enrolled from the three institutions. Both ABUS and HHUS will be performed on each patient before surgery. Breast radiologists independently review ABUS and HHUS images. They detect all visible lesions and record the location and size of them. They characterize all detected lesions by using BI-RADS category. The primary object is to compare the diagnostic performance of ABUS and HHUS as preoperative staging tool in women with known breast cancers. The sensitivities and specificity of each US mode for the detection of breast cancers are calculated on a per-lesion basis. McNemar's test and Fisher's exact test are used to compare the sensitivities and PPVs for ABUS and HHUS. Significance testing on the lesion level and patient level is conducted using generalized estimating equations (GEEs) with a logit link and an independent working correlation structure to adjust the effect of clustering on radiologists and patients. GEEs are utilized to compare the sensitivities and PPVs for ABUS and HHUS. Diagnostic performance are assessed with receiver operating characteristics curve analysis. Area under the curves are calculated from both parametric and trapezoidal curve fitting. Agreements between tumor size measured by each US mode and pathologic the tumor size are analyzed with the intraclass correlation coefficient (ICC) and 95% Bland-Altman limits of agreement.
The purpose of this study is to assess the efficacy of a fractional CO2 laser ("SmartXide2 - V2LR", DEKA M.E.L.A., Florence - Italy) "the Laser" in the treatment of genitourinary symptoms of menopause, female sexual function, and urogenital health in comparison to vaginal estrogen. Only breast cancer patients who have HR (-) breast cancer are planning to be included in the vaginal estrogen group.
This is a dose-escalating phase I using a rolling 6 design and randomized phase II study of ATI-450 in combination with chemotherapy testing the hypothesis that the combination of chemotherapy (paclitaxel or capecitabine) and ATI-450 will improve progression-free survival and reduce bone turnover, improve patient bone density, improve patient quality of life, and improve clinical efficacy.
The purpose of this study is to identify the highest tolerable dose of pyrotinib in combination with vinorelbine and to assess the safety and efficacy of the combination in Patients With HER2-Positive Locally Advanced or Metastatic Breast Cancer. The study will be conducted in two parts. In the first part, testing will be done on up to 12 subjects to determine the highest tolerable dose of pyrotinib and vinorelbine in patients with advanced solid tumors. In the second part of the study, we will explore the safety and efficacy of Pyrotinib + vinorelbine in Patients With HER2-Positive Locally Advanced or Metastatic Breast Cancer Who Have Received Prior Trastuzumab-Based Therapy. Participants will be treated until disease progression (PD), unmanageable toxicity, or study termination.
An ambispective observational registry study of pregnancy and breast cancer
This is a prospective, registry study that will enroll all women with early stage breast cancer who will be treated with intraoperative radiotherapy (IORT) during breast-conserving surgery. The purpose of this study is to further validate the long-term effectiveness and safety of this treatment method. We aim to assess short and long-term patient outcomes associated with IORT, including perioperative complications, local and distance disease recurrences, as well as disease-free survival and overall survival.
