Active clinical trials for "Breast Neoplasms"

The ultrasound imaging could be used to examine the thickness of dermis and the space between dermis and subcutaneous tissue. Whether the measurement of ultrasound imaging correlate to other measurement of edema is unknown. The purpose of this study is to investigate The reliability of measurement of edema using ultrasound imaging, and the correlation of measurement of ultrasound with other measurement tools. The different effect of edema control by manual lymph drainage technique and epidermis taping technique, and the cost-effective assessment. Our hypothesis : The measurement of edema with ultrasound imaging is a reliable method and correlate with other edema measurement with moderate correlation. Ultrasound measurement could demonstrate different effect of manual lymph drainage and epidermis taping, and different cost-effectiveness analysis.

This trial will compare the administration of 2 cycles of paclitaxel and cisplatin (DP) versus 4 cycles of CEF as adjuvant chemotherapy for the patients with locally advanced breast cancer and who were pathological partial response to DP as neoadjuvant chemotherapy. Those who had pathological complete response to DP will be randomized to have 2 cycles of DP or have no further chemotherapy.

The investigators designed this study to investigate the effect of aromatase inhibitors (AI) plus chemotherapy versus chemotherapy as neoadjuvant treatment in postmenopausal hormone receptor-positive breast cancer.

Bio-electrical impedance analysis and Tissue Dielectric Constant measurements are objective methods in clinical usage to detect lymphedema in early stage. The aim of this study is to reveal comparative relation these two methods on detecting lymphedema in an early stage.The another aim of this study is to determine impedance ratios and lymphedema index (L-dex) by using bio-electrical impedance analysis in patients after breast cancer surgery.

This international, multicenter, prospective single arm Phase II biomarker discovery clinical trial with the primary objective of assessing the association of PFS with gene mutations, gene copy number aberrations and gene signatures in post-menopausal women with hormone receptor positive, HER2-negative metastatic or locally relapsed breast cancer whose disease has progressed after prior adjuvant endocrine therapy or one line systemic treatment, i.e., endocrine treatment or chemotherapy, administered for metastatic disease.

Some women with breast cancer have their whole breast removed as part of their treatment (mastectomy). Of these women, around 31% have more surgery to create a new breast.There are two main ways to create a new breast(i)using tissue from elsewhere on the body ("autologous" reconstruction )or (ii)using a silicone implant. In recent years, it has been reported that by using a material called an "acellular dermal matrix" (ADM) the results of breast reconstruction surgery using an implant can be improved. ADMs are materials which originally come from animal or human skin. They act like a sling, supporting the lower part of an implant beneath the skin. Although ADMs have been approved for used in breast reconstruction and are safe, there is very little high quality evidence to back up their reported benefits, and some studies have suggested their use may in fact increase complications. The main purpose of this study is to find out what the actual risks and benefits of using an ADM in breast reconstruction surgery are. The investigators will follow the progress of women who have an implant based reconstruction to observe if participants develop problems; what those problems are and how participants feel about the results of their surgery. The investigators also follow the progress of women who undergo autologous reconstruction or alternative reconstructive techniques using an implant for the same reasons.

This multicenter placebo-controlled trial focuses on the efficacy and safety of acupuncture on breast-cancer related lymphedema. 200 participants will be recruited, and randomized in two groups: the real acupuncture group and the sham acupuncture group.

The purpose of this study is to compare the efficacy and toxicities of hypofractionated radiotherapy with conventional fractionated radiotherapy in high risk breast cancer patients treated with mastectomy. It's hypothesized that the efficacy and toxicities are similar between the two groups.

Breast cancer is the most common female malignancy in the world, and the leading cause of cancer-associated mortalities among women. Hormone receptors (HR) including ER and PR are the main prognostic factor for breast cancer patients. Breast cancer subtype was defined by ER, PR, HER2 and Ki67 status since the definition of intrinsic subtypes for breast cancer. Breast cancer which ER are positive have less aggressive and better long-term prognoses than other breast cancer subtype. Luminal B1 was definited as ER Positive, PR positive <20%, or Ki-67 ≥20% , and HER2-Negative. Although standard therapy to HR positive breast cancer is endocrine treatment, evidence reported that Luminal B1 breast cancers with lower PR expression are less sensitive to tamoxifen than luminal A breast cancers with higher PR expression, and the specific mechanism is not clear. We previously had a clinically analysed, and we found the Luminal B1 breast cancer had a significant proportion with 38%. Whether we need standard chemotherapy or chemotherapy based intensive endocrine therapy for those patients? In our research, we divided the patients with ER positive, PR negative, and HER-2 negative into two groups. One groups will be treated with 8 cycles of chemotherapy (EC×4-T×4). The other received 4 cycles of chemotherapy (TC×4) then will be given the intensive endocrine therapy (Goserelin acetate+Tamoxifen for young patients/Letrozole for postmenopausal patients). The primary endpoint is to assess disease-free survival (DFS) and overall survival (OS) in different regiments, the secondary endpoint is to assess the expression of female hormone levels. The correlation of the expression of female hormone levels with the clinical outcomes, so that the investigators could optimize adjuvant treatment regiment with luminal B1 breast cancer.

This is a phase IB/II clinical trial to evaluate the efficacy and safety of SHR6390 in combination with Letrozole or Anastrozole or Fulvestrant. Patients who have HR positive and HER2 negative recurrent/metastatic breast cancer and have not received systemic anticancer therapy are eligible for study.
