Active clinical trials for "Breast Neoplasms"

Triple negative breast cancer (TNBC), characterized by estrogen receptor, progesterone receptor and HER2 negative, accounts for 10-20% of all breast cancers and usually occurs in young women. It is an aggressive and worst prognosis breast cancer subtype, which urgently requires effective treatment.The pathological complete response (pCR) of neoadjuvant therapy is associated with disease-free survival (DFS) and overall survival (OS) of breast cancer. The correlation between pathological response and long-term survival in patients with early-stage breast cancer is the strongest among patients with triple-negative breast cancer.

The purpose of this study is to evaluate the clinical efficacy of acupuncture on chronic upper limb lymphedema in patients with breast cancer surgery

This is a multicenter, open, randomized, comparison study. Triple-negative breast cancer (TNBC) is a term applied to breast cancer cases that have <1% expression of the estrogen receptor (ER) and the progesterone receptor (PR) and do not over express HER2. Neoadjuvant therapy is often used to reduce the size of tumors, especially in locally advanced tumors. The purpose of this therapy is to make part of patients operable and to facilitate breast-conserving surgery. The purpose of this study is to assess the efficacy and safety of the following two proposals: nab-paclitaxel plus carboplatin versus nab-paclitaxel plus epirubicin, in order to provide support for rational clinical application. The total number of patients to be included in this study is 520 patients.

The proposed study is a randomized, parallel-group, placebo-controlled, subject- and assessor-blind trial. It is designed according to CONSORT and STRICTA recommendations. The 138 subjects will be randomly assigned to one of the two arms using block randomization in a 1:1 ratio: (I) acupuncture treatment, and (II) sham treatment. In groups (I) and (II), acupuncture or sham acupuncture treatment will be given twice a week for 6 weeks (12 sessions). A maintenance tapering treatment schedule will then be applied once per month for 3 months (3 sessions). The primary outcome will be improvement in sleep quality as measured by the change of ISI after 6 weeks of treatment. Secondary outcome assessment tools will include PSQI, HADS, BPI, BFI, FACT-B, sleep diaries, drug diaries, blinding success questionnaire and reports of adverse events. The subjects will be scheduled for on-site follow-up assessments at 3 and 6 months after the last treatment. An intention to treat (ITT) approach will be used for data analysis.

It has been well established that malignant tumors tend to have low levels of oxygen and that tumors with very low levels of oxygen are more resistant to radiotherapy and other treatments, such as chemotherapy and immunotherapy. Previous attempts to improve response to therapy by increasing the oxygen level of tissues have had disappointing results and collectively have not led to changing clinical practice. Without a method to measure oxygen levels in tumors or the ability to monitor over time whether tumors are responding to methods to increase oxygen during therapy, clinician's reluctance to use oxygen therapy in usual practice is not surprising. The hypothesis underlying this research is that repeated measurements of tissue oxygen levels can be used to optimize cancer therapy, including combined therapy, and to minimize normal tissue side effects or complications. Because studies have found that tumors vary both in their initial levels of oxygen and exhibit changing patterns during growth and treatment, we propose to monitor oxygen levels in tumors and their responsiveness to hyperoxygenation procedures. Such knowledge about oxygen levels in tumor tissues and their responsiveness to hyper-oxygenation could potentially be used to select subjects for particular types of treatment, or otherwise to adjust routine care for patients known to have hypoxic but unresponsive tumors in order to improve their outcomes. The overall objectives of this study are to establish the clinical feasibility and efficacy of using in vivo electron paramagnetic resonance (EPR) oximetry-a technique related to magnetic resonance imaging (MRI)-to obtain direct and repeated measurements of clinically useful information about tumor tissue oxygenation in specific groups of subjects with the same types of tumors, and to establish the clinical feasibility and efficacy of using inhalation of enriched oxygen to gain additional clinically useful information about responsiveness of tumors to hyper-oxygenation. Two devices are used: a paramagnetic charcoal suspension (Carlo Erba India ink) and in vivo EPR oximetry to assess oxygen levels. The ink is injected and becomes permanent in the tissue at the site of injection unless removed; thereafter, the in vivo oximetry measurements are noninvasive and can be repeated indefinitely.

The study is being conducted to evaluate the efficacy, safety and tolerability of pyrotinib combination with CDK4/6 Inhibitor SHR6390 in advanced HER2-Positive breast cancer patients who prior trastuzumab-treated.

This study is a single-arm, open, multi-center clinical study of nab-paclitaxel as the therapy ER+/HER2- recurrent metastatic breast cancer。

This is a prospective, open-label, real-word study evaluating the efficacy and safety of lapatinib in combination with chemotherapy versus trastuzumab in combination with chemotherapy in women with HER2-positive and p95HER2-positive ,or PI3K mutation, or PTEN loss breast cancer . Eligible subjects will have newly diagnosed breast cancer (Stage II-III) ; not have received systemic or local treatment . The primary endpoint was the rate of pathological complete response (pCR). The secondary objectives are to evaluate overall survival, overall response rate, clinical benefit response rate and the safety as well as tolerability of lapatinib plus chemotherapy and trastuzumab plus chemotherapy. Patients will receive lapatinib 1000 mg daily or trastuzumab 4 mg/kg intravenous (IV) load followed by 2 mg/kg IV weekly for a total of 12 weeks. After surgery, patients planned total duration of the anti-HER2 therapy will be one year.

Forty years ago clinical studies conducted by Ewan Cameron and Linus Pauling suggested that intravenous (IV) and oral ascorbic acid (AA) may diminish symptoms and could improve survival in terminal cancer patients. Previous phase I and II clinical trials have found that high dose (1.5g/kg ) iv AA is well tolerated in cancer patients. This is a phase I/II, randomized study of parenteral administration of Ascorbic Acid (AA) as a supplement to the conventional neo-adjuvant chemotherapy in women with breast cancer.

This is a multicenter, open, single arm dose escalation and dose expansion clinical study to evaluate the safety, tolerability, pharmacokinetics, and antitumor activity of FCN-437c alone or in combination with letrozole in women with ER +/ HER2 - advanced breast cancer.
