The objective was to find out the impact of COVID-19 on stage of breast cancer at presentation and its effects on overall onco-surgical management. The investigator carried out this research to see the presenting stage of breast cancer in the participants in this pandemic and correlate its effect on stage of breast cancer and upstaging of disease
This is a single center, randomized, blind, parallel controlled clinical trial. The primary objective is to evaluate the single dose pharmacokinetics of recombinant Humanized anti-HER-2 monoclonal antibody injection GB221 in comparison with Herceptin ® in Chinese healthy adult volunteers. The main aim is to study the pharmacokinetic similarity between GB221 and Herceptin ®.
pilot study on physical therapy in women with breast cancer immediately following surgery
The current study aims to determine the diagnostic accuracy of Magnetic Resonance Imaging (MRI) and Positron Emission Tomography- Computed Tomography (PET-CT) in predicting a pathological response of molecular subtypes of breast cancer to neoadjuvant chemotherapy (NAC).
SurgiNose is a single-center, non-randomized feasibility study aiming to evaluate the feasibility of intraoperative tissue analysis using differential mobility of surgical smoke generated with electrocautery. Patients receive standard-of-care breast conserving surgery.
Due to their genetic instability, breast tumors that do not express receptors for Estrogens, Progestagens or amplify the Her2 / neu oncogene [called triple-negative breast cancer (TNTC)] and other tumors such as melanoma, non-small cell lung cancer, accumulate numerous mutations that make them highly resistant to different regimens of chemo- or radiotherapy, thereby generating high morbidity and mortality. However, immunology can turn the genetic instability of tumors into the Achilles' tendon. Evidence of this has been revealed in Phase I clinical studies in patients with melanoma and lung cancer in an advanced stage of metastasis treated with Ipilimumab (anti-CTLA4) to decrease immunosuppression, in whom peptides containing mutations presented in Major Complex molecules Histocompatibility of Class I (HCM I) of the tumor itself results in their recognition as "foreign" neo-antigens leading to the efficient destruction of the tumor by anti-tumor CD8 + T lymphocytes that are amplified when they are vaccinated with these peptides. For this reason, the identification of non-synonymous mutations of single amino acid and vaccination with 25 amino acid peptides that incorporate these mutations (synthetic vaccines) is emerging today as an alternative for immunotherapy of cancers responsible for high mortality in humans. In an approach that takes 16 weeks, today, it is possible to go from the analysis of the tumor's transcriptome (which allows identifying the universe of tumor mutations) to the patient's vaccination with a personalized vaccine that contains neo-antigens of his tumor. TNBC is the most aggressive breast tumor, representing around 25% of breast cancers in our environment. While generally, at least 30% of women with other types of metastatic breast cancer survive 5 years after diagnosis, most patients diagnosed with metastatic CMTN die within this time. The lack of selective therapies and the poor prognosis of patients with NTMC make their therapeutic management difficult, so the implementation of new therapies for this type of tumor is the main focus of researchers who seek more effective and selective treatments to improve the life expectancy of patients without compromising their quality of life. The genetic instability and high rate of mutations of the TNBC most likely favor the generation of neo-epitopes. Still, due to the immunosuppressive environment of the tumor, it escapes the immunosurveillance of the immune system. Despite the high mortality induced by this tumor, a percentage of patients treated with neoadjuvant chemotherapy with agents such as Doxorubicin and Cyclophosphamide (AC) + Taxanes respond to this chemotherapy regimen. In particular, the anti-tumor effect of AC is attributed to two things: (i) the direct cytotoxic effect on the tumor cell, (ii) the immunostimulation of T lymphocytes promoted by Immunogenic Cell Death (ICM) selectively induced by these drugs. Therefore, in this project, we propose to carry out the first clinical study in Colombia of vaccination of patients with TNBC with synthetic peptides that contain mutations of their own tumor to evaluate the immunogenicity and safety of this type of personalized vaccine as a therapeutic alternative for this tumor. Achieving the specific objectives set out in this project would mean that we have been validated in Colombia the experimental design necessary to identify unique epitopes in tumors and demonstrate the safety and immunogenicity of these vaccines. We consider that having achieved the above; we will have taken an important step towards the implementation in our country of the use of this type of vaccine for immunotherapy not only of TNBC but of other tumors such as glioblastoma, gastric, esophagus, and pancreas, highly fatal due to its high mutation rate.
Background Radio Isotopes and Blue dye alone or in combination are the most commonly used tracer agents in sentinel Node Biopsy for early breast cancer. Recent studies have found fluorescence method using Indo Cyanine Green as a promising technology with fewer disadvantages. This study represents the first within a North African setting. Methods Retrospective analysis of our database that includes patients with clinically node-negative breast cancer scheduled for breast surgery and SN biopsy between 2016 and January 2021. Patients who underwent detection using fluorescence-ICG were included in this study.
The present randomised controlled trial aimed to investigate the effectiveness of a clinical decision support system (CDSS) in assisting clinicians to apply nutritional care to breast cancer (BC) patients during the COVID-19 pandemic in Greece. Adult BC women (stages I-IIIA) who underwent mastectomy followed by hormone therapy were randomly assigned either to the Control group, receiving general nutritional advice, or the Intervention (or CDSS) group, in whom a personalised nutritional programme based on the Mediterranean diet together with physical activity guidelines were provided, all produced by CDSS. Medical and dietary history, anthropometrics, biochemical indices and quality of life characteristics were assessed both at baseline and at the end of the study (3 months).
The status of the axillary lymph nodes is one of the main prognostic factors in breast cancer (BC). SLNB is currently the standard staging method for patients with clinically node-negative (cN0) breast cancer. In patients with a positive SLN and in those with affected lymph nodes at the beginning (cN+), LND is the standard of treatment.
To develop application-enabled shared decision-making among patients with early breast cancer and evaluate the preliminary effects of the interventions.
