Filter by:To learn if applying vapocoolant anesthetic spray ("Nüm") on the surface of the intended injection site will reduce the pain/anxiety associated with breast injections.
The study will assess whether changes in kinetic parameters of tumor and peritumoral vasculature using ultrafast dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) during neoadjuvant chemotherapy (NAC) are predictive of pathologic complete response (pCR) in patients with breast cancer appropriate for NAC. pCR is defined as having no residual invasive breast cancer or ductal carcinoma in situ.
HS-10502 is a Poly(ADP-ribose) polymerase 1 (PARP1)-specific selective inhibitor. The purpose if this study is to assess the safety, tolerability, pharmacokinetics (PK), and efficacy of HS-10502 in subjects with homologous recombination repair (HRR) gene mutant or homologous recombination deficiency (HRD) positive advanced solid tumors.
Chemotherapy is toxic and challenges everyone differently. Most chemotherapy side-effects are known and well documented. However, the phenomenon of "chemo fog" also known as "chemobrain" has not been fully investigated and is often based on comments of breast cancer patients attending outpatient clinics during and after their chemotherapy. Changes in thinking ability like lack of concentration, loss of memory and the inability to hold a thought or even a conversation has a significant impact on the lives of breast cancer patients. Without understanding what "chemobrain" is, and what causes it, there is little that doctors can do to help at the moment. The team proposing this study believe that chemotherapy causes chemicals associated with inflammation to attack parts of the brain that are important for concentration and making new memories. Unfortunately, it is not possible to measure these chemicals directly in the brain, but we believe that a brain scan sensitive to excess iron, a marker of brain inflammation, can help. This project will measure thinking ability, such as memory and concentration, take a blood sample and do a brain scan before, during and after a patient has chemotherapy. We will then look for changes in iron in the brain areas that are important for concentration and memory and compare those to changes in thinking ability and to levels of inflammation chemicals in the blood. This information will be essential to help plan our next step which is to test ways to reduce the effects of "chemobrain".
The ETERNITY study is an international, multicenter, observational study that aims to follow up patients who have participated in a GBG trial for early breast cancer, even after the study has officially ended, in order to collect long-term data on survival, late or delayed adverse events, in addition to information related to pregnancy, fertility and other parameters impacting quality of life.
Breast cancer remains the most common type of cancer in the world. Cancer itself and chemotherapy treatment, which is one of the most important treatment steps, may cause unwanted physical, social and psychological effects (symptoms) for the patient. These effects significantly affect the patient's quality of life. It is possible to manage the symptoms and reduce their destructive effects with professional care and treatment support that includes evidence-based practices. On the other hand, breast cancer patients receiving chemotherapy during the Coronavirus Pandemic form the risk group in terms of infection; On the one hand, the continued treatment and care support, on the other hand, required changes in the approach to the patient in order to reduce the risk of infection. In addition to reducing the risk of infection, mobile applications can create an alternative during the coronavirus Pandemic. process in order to maintain quality and uninterrupted care and treatment. This study is planned to be conducted analytically in a randomized controlled single-blind pattern in order to determine the effect of the interactive nurse support program developed with the mobile application on the patient outcomes (symptom management, quality of life, social support perception and anxiety) in breast cancer patients who received chemotherapy during the coronavirus pandemic. Within the scope of the study, interactive nurse support developed with mobile application will be applied to the research group from patients who apply to the polyclinic to receive chemotherapy treatment, and the control group will receive standard care. As a result of the analysis of the data collected systematically with forms and scales, the effect of the interactive nurse support program developed with the mobile application on patient outcomes (symptom management, quality of life, social support perception and anxiety) will be evaluated and recommendations will be made regarding the use of the application in patients with breast cancer.
Hypoxia and reduced oxygen partial pressure is commonly occurring after abdominal surgery. This study aims to investigate whether similar changes also occur after breast cancer surgery. Inclusion: 60 women undergoing breast cancer surgery. Exclusion: Dementia or cognitive impairment that makes it impossible to participate in the study. Arterial blood gas and lung function are undertaken before surgery and the day after surgery
Although treatment is started with surgery in early stage tumors depending on the molecular subtype, neoadjuvant chemotherapy is the initial treatment in locally advanced tumors or if axillary lymph node involvement is present. Axillary lymph node dissection (ALND) has been used for a very long time in the traditional approach to the treatment of breast cancer. The current approach in patients with early stage, clinically negative breast cancer of the axilla is sentinel lymph node biopsy (SLNB). SLNB is done to evaluate the axilla in both early stage tumors and suitable patients after NAC. According to ACOSOG Z1071, when at least 3 lymph nodes were removed using lymphoscintigraphy and blue dye for SLNB, the false-negative rate was found to be less than 10% in patients with proven axillary involvement, and SLNB was shown to be feasible after NAC. Targeted axillary dissection (TAD) is a procedure that includes SLND with removal of the lymph node identified and marked as containing metastatic disease before treatment. Multiple clinical studies have shown that TAD is a viable option to reduce false-negativeness in patients with breast cancer after NAC. In patients with axillary involvement, a metallic clip is placed in the suspected lymph node prior to neoadjuvant therapy and a radioactive iodine-125 seed is implanted into the target after completion of chemotherapy, and during TAD, the core node is removed using a radioactive probe. Today, the applicability of these procedures is difficult due to both the cost and the absence of nuclear medicine units in some hospitals. For this reason, alternative methods that can be applied more easily in the evaluation of the axilla after NAC are being investigated. SPOT ENDOSCOPIC MARKER is an FDA (American Food and Drug Administration) approved Carbon Black Tattoo paint that has been used for a long time to mark lesions in the gastrointestinal tract. Its shelf life is 20 months. In our project, in patients with lymph node involvement in the axilla who have had a metallic clip placed with biopsy before NAC, the lymph node will be marked with a Spot Endoscopic Marker simultaneously, and the permanence of the spot marker dye will be evaluated by excising the clip-marked and black-painted lymph node in addition to the methylen blue injected during the operation. The reliability of the use of Spot Endoscopic Marker, which is much cheaper instead of clips, for permanent axillary marking in TAD will be evaluated.
Incyclix Bio (Incyclix) is developing INX-315 as an oral, small molecule inhibitor of cyclin dependent kinase 2 (CDK2) for the treatment of human cancers. This first-in-human study is designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary antitumor activity of INX-315 in patients with recurrent advanced/metastatic cancer, including hormone receptor positive (HR+)/Human Epidermal Growth Factor Receptor 2 Negative (HER2-) breast cancer who progressed on a prior cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) regimen, and CCNE1-amplified solid tumors who progressed on standard of care treatment. This study will evaluate approximately 6 dose levels of daily INX-315 in Part A, at least two dose levels will be evaluated in Part B to identify the Recommended Phase 2 Dose (RP2D) in patients with ovarian cancer, and Part C will evaluate combination treatment of INX-315 plus a CDK4/6i and selective estrogen receptor degrader (SERD) in HR+/HER2- breast cancer patients who have progressed on prior CDK4/6i regimen.
Recent advances in technologies, such as microarray and high-throughput sequencing, represented a deeper understanding of molecular biology, especially noncoding RNA (ncRNA). It was found that there are only <2 % of the total genome sequence as protein-coding genes while at least 98 % of the genome are transcribed into ncRNA. In the past, non-protein-coding RNAs were known as "transcription noise," but now it is obvious that ncRNAs play a crucial regulatory role in cell differentiation and organism growth and metabolism.
