Filter by:Capecitabine combined with pyrotinib is the standard protocol for HR+/HER2+ advanced breast cancer after trastuzumab failure, but the incidence of grade 3 hand-foot-syndrome was 16.4%. Therefore, the search for efficient and low toxicity alternatives has become a research hotspot. Our previous basic studies have shown that ER inhibitor fulvestrant and HER2 inhibitor pyrotinib have a synergistic effect. The preliminary analysis of our prospective shows that the efficacy is close to that of capecitabine combined with pyrotinib, and the adverse events are significantly improved compared with capecitabine combined with pyrotinib. Therefore, it is necessary to further carry out a head-to-head phase III randomized controlled clinical trial to study the efficacy and safety of fulvestrant combined with pyrotinib in the treatment of HR + / HER2 + advanced breast cancer.
More and more evidence suggests that local radiotherapy can improve the outcomes for patients with oligometastatic disease. The purpose of this study is to assess the impact of radiotherapy, compared with standard systemic therapy alone, on survival, local control and toxicities in patients with extracranial oligometastatic breast cancer. Eligible patients are randomized in a 1:2 ratio between the control arm (standard systemic therapy), and the WLRT arm (standard systemic therapy + radiotherapy). Randomization will be stratified by three factors: visceral metastasis (yes vs.no), number of metastases(≤2 vs. >2), hormone receptor(positive vs. negative). SBRT technique is preferred. During and after radiotherapy, the patients are followed and the efficacy and toxicities of radiotherapy are evaluated.
This study aim to determine kinetic of post treatment recovery/variation of a panel of innate and adaptative immune system cells and molecules. The results should allow to determine the optimal post treatment immunomonitoring timing and panel to be used for future studies.
Breast cancer is the most common cancer of women. Surgery for early breast cancer includes axillary lymph nodes staging. Axillary surgery may lead to intractable complications like permanent arm swelling. Axillary sentinel lymph node biopsy (SLNB) has been introduced to minimize the incidence of these complications. Several methods are routinely used for identification of the sentinel node during operation. Some of these methods necessitate facilities that are not universally available; specially in countries with limited resources. In its simplest form, SLNB using the methylene blue dye technique has an identification rate of 88-94%. If the sentinel node can not be identified, full axillary dissection may be required and the risk of arm swelling is increased. The objective of this study is to maximize the identification rate of the sentinel node thus avoiding the need for extensive axillary surgery. The investigators assumed that preoperative tattooing of the suspicious lymph node during ultrasonographical imaging may help the surgeon in localizing the sentinel lymph node. In this study, the sonographer will perform preoperative tattooing of the suspicious node. The surgeon will perform SLNB by the methylene blue dye. The sensitivity of ultrasonographical tattooing relative to SLNB will be calculated. The study will determine if the tattooing technique may localize additional nodes that are missed by the methylene blue.
Currently there are five trastuzumab biosimilars approved by EMA (Ogivri® Mylan , Herzuma® Biogaran, Ontruzant® MSD, Trazimera® Pfizer, and Kanjinti® Amgen) for the treatment of HER2-positive breast cancer. EMA's approvals were obtained on phase I pharmacokinetic equivalence trials and phase III clinical trials based on efficacy primary endpoints in the neoadjuvant setting and on Overall Response Rate in metastatic setting. Safety was a secondary endpoints in these trials. Phase III pivotal trials compared trastuzumab biosimilars to Herceptin® in combination with chemotherapy in the neoadjuvant setting and in the metastatic setting. The trials were designed before the approval of pertuzumab (in the neoadjuvant and metastatic settings). Thus, there is no available prospective data on the safety and efficacy of trastuzumab biosimilars in combination with pertuzumab. A biosimilar compound can obtain an extrapolation of its indications to those of the reference biological product since bio-similarity has been demonstrated (ie pharmacokinetic equivalence and clinical studies in the most "sensitive" indications). To date, the use of trastuzumab biosimilar in combination with pertuzumab is allowed, but this combination is not supported by neither scientific evidence nor clinical guidelines. PETRA aims at evaluate the efficacy and safety of the combination of pertuzumab and a trastuzumab biosimilar in real life.
The aim of the present study is to determine the effects of 12 weeks of multicomponent training associated with a health education program carried out remotely, compared to a health education-only program, on psychological and physical outcomes of women in primary treatment for breast cancer. For that, 36 women will be randomized to a multicomponent training group carried out remotely associated with health education or health education group. The psychological and physical outcomes will be measured pre (week 0) and post-intervention (week 13) in both groups, always by the same investigator blinded in relation to the groups. The multicomponent training group will carry out an exercise program twice a week, and health education will also be carried out on one of the two days. In this group, the conversation on the topic of the week will take place during stretching. The sessions (on pre-established and non-consecutive days) will be held by video call (approximately 60 min) in small groups (maximum three participants) and will be given by students of the Physical Education course, previously trained to perform the intervention. The order of the multicomponent training will be joint mobilization, aerobic stimulus, balance exercise, strength exercises and stretching of the main muscles used during the training session. For the participants of the health education group, also, once a week, a material with several topics related to the management of breast cancer diagnosis and physical activity will be sent by message. In addition, two days after this material is sent, a conversation will be held with the participants of this group, at a google meet of approximately 30 minutes, about the theme sent by message. The themes will be depression, pain, fatigue, body image, symptoms in the arm and breast, vasomotor symptoms, neuropathy, arthralgia, sexual dysfunction, quality of life, physical activity and eating habits. To analyze the outcomes collected, it will be used Generalized Estimating Equations (GEE) and the Bonferroni post-hoc test.
This is a global extension study to provide continued access to niraparib and further characterize the long-term safety of niraparib treatment in participants who are currently receiving treatment with niraparib within GlaxoSmithKline/TESARO-sponsored studies (NCT01847274, NCT02354586, NCT01905592, NCT03308942, NCT02657889) that has fulfilled the requirements for the primary objective.
Nipple-sparing mastectomy (NSM) with immediate breast reconstruction (IBR) is a form of mastectomy that achieves optimal disease control and facilitates reconstruction. The study aimed to assess the oncological safety and aesthetic outcomes of nipple-sparing mastectomy and immediate breast reconstruction. 35 female patients with breast cancer were included in the study. The investigators categorized the incisions into radial, inframammary, and periareolar incisions with planned reconstruction types; direct to implant (DTI), transversus rectus abdominis myocutaneous (TRAM) flap, latissimus dorsi myocutaneous (LD) flap, or LD with implant.
The prevalence of shoulder joint disease is high in breast cancer patients. The cause of adhesive capsulitis is not clearly identified. However, the following are known as relevant factors that are the restriction of the use of the arm after surgery, inflammation due to autoimmune action, radiation therapy, and adhesion of the surgical site. The purpose of this study is to compare and analyze the effect of intrathecal steroid injection in breast cancer survivors with adhesive capsulitis.
The goal of this study is to compare the study drug, sacituzumab govitecan-hziy, versus doctors' treatment of choice in participants with HR+/HER2- metastatic breast cancer (MBC) who have failed at least 2 prior chemotherapy regimens.
