Filter by:FEGALA is a comparative, multicenter, randomized, prospective, open-label study comparing the results observed at 3 months (± 15 days) on the EORTC QLQ-C30 scale in a group of patients with metastatic cancer followed on an outpatient basis and benefiting from the CONTINUUM+ CONNECT solution (with or without nursing support at home) versus comparable patients benefiting from conventional monitoring.
The current observational study aims to perform the sentinel lymph node in breast cancer in the usual way with technetium 99 and add a second tracer, indocyanine green. The objective is to evaluate the detection rate of the lymph node with indocyanine green compared to the usual technique.
Sentinel lymph node biopsy (SLNB) is the standard procedure to stage the axilla in clinically node-negative invasive breast cancer (IBC) patients undergoing upfront surgery. The ACOSOG-Z0011 and the AMAROS trial demonstrated that SLNB with or without radiotherapy provided equivalent local control and survival to axillary lymph node dissection (ALND) in early-stage breast cancer patients with 1 or 2 positive SLNs. However, the ACOSOG-Z0011 trial did not included patients treated with mastectomy, and the AMAROS trial only included 17% of mastectomy patients. The investigators conduct an observational cohort study of early stage breast cancer patients receiving upfront mastectomy with 1 or 2 macrometastases after SLNB. The study aim to demonstrate a 5-year disease-free survival of not less than 80% when ALND is omitted and replaced by axillary radiotherapy, and determine the axillary recurrence rate.
A Single-center, open, prospective study，for analyzing the local recurrence rate, the incidence of incision complications and the aesthetic effect of intraoperative radiotherapy in early breast cancer patients after breast-conserving surgery.
Evaluate the efficacy and safety of Ribociclib in combination with NSAI versus physician's choice of chemotherapy sequential endocrine therapy in HR+/HER2- advanced breast cancer.
The primary objective of the investigators is to develop an integrated algorithm for surgical treatment of chronic lymphedema after breast cancer surgery. This will be achieved by retrospectively analysing a subgroup of patients who had breast cancer-related surgery prior to lymphedema.
The prognosis of recurrent and metastatic triple negative breast cancer (TNBC) is poor, and chemotherapy is still the main treatment for TNBC. Some studies have shown that combination therapy of antibodies targeting cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed cell death-1 (PD-1) significantly improves clinical benefit over PD-1 antibody alone. However, broad application of this combination has been limited by toxicities. Cadonilimab is a humanized immunoglobulin G1 bispecific antibody targeting PD-1 and CTLA-4. It mutates to eliminate Fc receptor and complement-mediated cytotoxic effects. The purpose of this study is to evaluate the efficacy and safety of Cadonilimab combined with chemotherapy as a first or second-line treatment of recurrent and metastatic TNBC. This study is a multicenter, single arm, phase II, non randomized, open label, Simon two-stage design. It is planned to enroll 27 late stage TNBC patients.
This study has as goal to evaluate the use of abemaciclib and bicalutamide in androgen receptor positive metastatic triple negative breast cancer.
This study evaluates the acute toxicity and feasibility of repeat breast conserving therapy with preoperative accelerated partial breast re-irradiation (PAPBI) in female patients aged 51 years or older with ipsilateral recurrent or second primary low-risk breast cancer.
The goal of this study is to evaluate the safety and clinical efficacy of personalized chemotherapy with low doses of cyclophosphamide administered taking into account the reparative cycle of tumor cells in participants with breast cancer (stage IV or disease progression). The main question it aims to answer is: Does personalized chemotherapy of breast cancer with low doses of cyclophosphamide, taking into account the reparative cycle of tumor cells, lead to a significant reduction in tumor size and improvement in the visual status of controlled tumor foci relative to their initial state? During the preparatory stage, a tumor sample from participant is harvested intraoperatively. The primary culture is obtained from this tumor tissue sample. Repair cycle time is estimated, and the day when tumor cells are synchronized at the cell cycle G2/M phase is identified. The schedule of administering cyclophosphamide and DNAmix complex composite preparation is calculated according to the resulting time points. According to the elaborated regimen, the participant receives 4 intravenous cyclophosphamide injections at the dose of 300 mg/m2 in combination with 4 injections of 1-12 mg of DNAmix administered into prominent tumor nidi and lymph depots. The participant receives from 2 to 6 courses of therapy. The interval between courses is 21 days.
