Filter by:A multicenter, randomized, open-lable, single-dose, two-cycle, double-cross bioequivalence study comparing the pharmacokinetic profile of LY01612 (Doxorubicin hydrochloride liposome injection) and CAELYX® in Chinese subjects with advanced breast cancer
This community-engaged research project will test an adapted online breast cancer screening decision aid to address the needs of women living in an area where environmental contamination has increased concern about breast cancer risk. It will provide novel data on individual experiences with breast cancer risk assessment and decisional determinants of screening choices in a community disproportionately impacted by industrial pollution.
1. Measurement of serum levels of Retinoic acid induced 14 (RAI14) and Metastasis associated cancer colon -1 (MACC-1) as biomarkers for diagnosis of breast cancer. 2. Study their relationship to disease stages and clinicopathological features of BC. 3. Compare the diagnostic performance of serum RAI14 and serum MACC-1 with serum Carcinoembryonic antigen (CEA) and Cancer antigen 15-3 (CA15-3) for diagnosis of BC.
This study aims to evaluate the feasibility of using See.d instrument and SBS slides for preparation of plasma and cytological samples from whole blood. Forty-five participants will be enrolled (20 healthy volunteers and 25 metastatic breast cancer patients) and each participant will be asked to provide a blood sample.
The standard treatment for locally advanced and node-positive breast cancer is surgery following neoadjuvant chemotherapy (NAC). Using NAC in advanced-stage tumors and biologically aggressive subtypes can lead to de-escalation in surgical treatment for the breast and axilla. Previously, NAC was believed to alter lymphatic drainage due to fibrosis and tumor emboli in lymphatic channels. However, the theAmerican College of Surgeons Oncology Group (ACOSOG) Z1071 and Sentinel-lymph-node biopsy in patients with breast cancer before and after neoadjuvant chemotherapy (SENTINA) trials investigated the performance of sentinel lymph node biopsy (SLNB) after NAC in patients with proven axillary lymph node involvement at the initial biopsy. In contemporary breast cancer management, particularly in the axillary approach, less invasive techniques are becoming increasingly common. This raises the question of whether there might be a patient group where SLNB could be avoided. In this study, the investigators sought a new method to evaluate the axilla after NAC in patients with known axillary involvement previously. For this purpose, the investigators performed an ultrasound-guided needle biopsy on the clipped axillary lymph node with known metastasis before the planned surgery, aiming to assess the axilla without performing SLNB after treatment. Additionally, the investigators investigated which patient group might benefit more from this predictability based on molecular subtypes and clinical-pathological features.
The goal of this prospective study is to develop MRI-based models representing tumor microenvironment in participants with invasive breast cancer. The main purpose of this study is to analyze the association of diffusion-, T2-, and dynamic contrast-enhanced T1-weighted images of 3T MRI before treatment with the immunohistochemical reactivity of tumor microenvironment including the extracellular matrix and immune cells of core-needle biopsy specimens For this purpose, investigators extract 16145 radiomic features from the intratumoral and peritumoral regions on MRI of participants with invasive breast cancer before treatment.
It is estimated that there are 420,000 newly diagnosed breast cancer patients in China in 2020. With surgery, radiotherapy, chemotherapy, endocrine, targeted therapy and other treatment methods going hand in hand, the outcome of breast cancer patients has been greatly improved. However, along with the comprehensive treatment of breast cancer, there will also be some corresponding complications, including breast cancer-related lymphedema （BCRL）， is one of the most common and serious complications. the incidence of BCRL in the patients with axillary dissection11% -57%, average 28%, Arm lymphedema seriously affect the quality of life of breast cancer patients, is known as the last kilometer of breast cancer patients to return to society. The related risk factors mainly include surgery, radiotherapy, body mass index, (BMI), etc. Accordingly, a series of measures appeared to prevent the occurrence of BCRL, including surgical and non-surgical methods, The main surgical methods include lymphatic microsurgical preventing healing approach (LYMPHA), and axillary reverse mapping to retain arm lymph nodes.the LYMPHA technology requires skilled microsurgery technology, or multidisciplinary participation, which will prolong the operation time.The retention of arm lymph nodes may involve tumor safety.Non-surgical methods include elastic sleeve wearing, functional exercise, arm resistance training, manual drainage, etc. The manual drainage is time-consuming and requires therapist participation, and the evidence that resistance training can prevent edema is insufficient.The elastic cuff has been proven to effectively prevent the occurrence of BCRL, and it can prevent the accumulation of extracellular fluid caused by surgery, chemotherapy and radiation therapy, and gravity factors. A randomized controlled study (CTRI / 2017 / 12 / 010762) released by Paramanandam VS et al, Tata Memorial Hospital, tertiary Cancer Center, Mumbai, India, that wearing compression sleeves (20-25mmHg) can reduce and delay the occurrence of arm swelling in the first year after breast cancer surgery. However, the higher pressure sleeves still has a negative impact on patients' quality of life and patient compliance. Ochalek K have shown that the primary pressure sleeves (15-20mmHg) is also effective in preventing the occurrence of lymphedema, but the randomized controlled study has a small sample size and insufficient evidence.
The liver represents the third most common site of breast cancer (BC) metastases behind the lymphatics and bone. The primary treatment for BCLM remains chemo-therapy and, more recently, targeted immunotherapy. The role of liver resection in BCLM remains controversial. The primary aim of the study is to compare the efficacy of liver resection vs. medical therapy alone in Breast Cancer Liver Metastasis (BCLM) patients.
The purpose of the study is to determine the recurrence rates and survival of patients with clinical T1-2N0 ER+/Her2- invasive breast cancer who have biopsy proven image detected nodal disease treated with upfront lumpectomy or mastectomy with TAD followed by adjuvant therapy. This is a prospective, single arm phase II clinical trial. Patients will be screened and enrolled per eligibility criteria. Patient, tumor, and treatment data will be documented.
This study will address the female patients who are exposed to surgery after breast cancer. strength training for the inspiratory muscles will be applied in addition to the traditional care including physical therapy that will be compared to the effect of the traditional care alone on multiple outcome measures such as muscle strength, function, fatigue, and stress.
