Filter by:The use of fluorescence for real-time evaluation of organ and tissue vascularization and lymph node anatomy is a recent technology with potential for the surgical treatment of cancer. The real-time analysis of tissue vascularization allows immediate identification to the surgeon of areas with greater or lesser blood circulation, favoring surgical decision making and prevention of complications related to tissue ischemia (necrosis, dehiscences and infections). It is a technology with potential application in the areas of Digestive Surgery, Repairing Plastic Surgery in Oncology, Head and Neck Surgery. In addition, fluorescence can be used as a method to identify lymph node structures of interest in the oncological treatment of patients with urologic, gynecological and digestive tumors. Introduced by Pestana et al. In the late 2000s, the perfusion mapping system through intraoperative indocyanine assisted laser angiography (SPY Elite System © LifeCell Corp., Branchburg, N.J.) had its initial application in repairing surgery after breast cancer treatment. The method proved to be useful in the prevention of ischemic and infectious complications in cancer surgery. Pestana, in a prospective clinical series of 29 microsurgical flaps used in several reconstructions, observed a single case of partial loss of the flap, the present technology having a relevant role in intraoperative decision making. In the same year, Newman et al. The first application of the system in breast reconstruction surgery. In an initial series of 10 consecutive cases of reconstruction with microsurgical flaps, in 4 cases the system allowed the intraoperative identification of areas of low perfusion, thus changing the surgical procedure. According to the authors, there was a 95% correlation between indocyanine laser assisted and subsequent development of mastectomy skin necrosis, with sensitivity of 100% and specificity of 91%. Similarly, Murray et al. Evaluated the intraoperative perfusion, however, of the areola-papillary complex in patients submitted to subcutaneous mastectomies with satisfactory results in terms of predictability of cutaneous circulation. Other authors in larger clinical series and evaluating other procedures have observed valid results in terms of prevention of complications. Vascular perfusion of anastomoses and fistulas following bowel surgery for cancer remain a serious and common complication. These fistulas can be caused by insufficient perfusion of the intestinal anastomosis. Intraoperative angiography with indocyanine assisted laser can be used to visualize the blood perfusion following intravenous injection of the indocyanine green contrast. Several groups reported the ability to assess blood perfusion of the anastomotic area after bowel surgery. Although they studied retrospectively, Kudszus and colleagues described a reduction in the risk of revision due to fistula in 60% of patients whose anastomosis was examined using laser fluorescence angiography compared to historically paired patients without this method. The same principle can be used to evaluate the tubulized stomach to be transposed to the cervical region after subtotal esophagectomy. Currently, fluorescence-guided sentinel lymph node mapping has been studied in breast cancer as well as investigative character in colorectal cancer, skin cancer, cervical cancer, vulvar cancer, head and neck, lung cancer, penile cancer, cancer Endometrial cancer, gastric cancer and esophageal cancer. These early studies demonstrated the feasibility of this methodology during surgery. Comparison of laser fluorescence images on blue dyes indicate that fluorescence images can replace blue dyes because they exceed them due to increased tissue penetration depth and absence of staining in the patient and cleaning of the operative field. To date, there are no clinical studies involving intraoperative perfusion mapping and identification of lymph node structures with the SPY Elite System © system or other platforms (Pinpoint or Firefly) in Brazil that evaluate the Brazilian population. In an objective way the influence of this technology as predictive in the better or worse evolution of the oncologic surgery as well as in the prevention of the local ischemic complications by means of intraopeal change of conduct
The purpose of the study is to evaluate the safety, tolerability, and pharmacokinetics of escalating single-dose of UB-921 in healthy male volunteers.
The optimal dose of iodine based contrast agents used in contrast-enhanced spectral mammography (CESM) is unknown. If CESM, performed with lower dose of iodine based contrast agent, visualizes a tumor comparable to CESM with regular dose of contrast agent, patients can receive less contrast agent for CESM in future and thereby risking less side effects of the contrast agent. In order to study whether CESM remains unchanged at smaller amounts of contrast administration, a second CESM exam will be performed within one week of the first with a an alternative amount of contrast, it being either 80%, 60% or 40% of the original contrast dose. The settings of the CESM unit will remain unchanged.
The purpose of this study is to invite all people diagnosed with cancer who meet the eligibility criteria to complete questionnaires before their treatment begins and at regular intervals over time to assess the impact of cancer and its treatment on people's lives in the short, medium and long term. We will explore a range of factors to determine their role in both recovery of health and well-being and self-management. Although it is known that people who have had cancer are likely to experience a number of physical and psychological problems as a result of the disease and treatment, it is not known what the 'typical' course of recovery of health and well-being looks like, how long it takes and how this can be influenced. We will determine pathways to recovery of health and well-being following cancer diagnosis (initially breast cancer diagnosed <50 years, Non-Hodgkin Lymphoma and gynaecological cancers) and identify what factors influence this. This includes assessing the relative importance of the person's illness, personal attributes, perceived burden of treatment, role of the environment they live in, including health / social care and personal networks of support, and their ability and capacity to self-manage. We will identify who is most at risk of problems and what environmental supports and resources people are able to mobilise to support their self-management. We will also explore who has the confidence and ability to manage during and beyond treatment and what factors influence this and whether this leads to earlier problem resolution and restoration of health and well-being. This knowledge will be used to develop and test future supportive interventions to enhance the rapid recovery of health and well-being - our long term aim being to design ways of helping people with cancer in areas we identify as problematic for them.
Women who have undergone breast cancer surgery may develop swelling of the arm on the side the breast cancer occurred. If the swelling becomes chronic it is called lymphedema. This study will examine the effect of a 12-week decongestive progressive resistance exercise with advanced compression on breast cancer related lymphedema. Our objective is to determine if breast cancer survivors are willing and able to wear advanced compression while exercising and if the combination will help to reduce their lymphedema. Twenty-four breast cancer survivors from Edmonton, Alberta will be enrolled in the one-year long study.
This is a study to investigate the potential clinical benefit of G1T38 as an oral therapy in combination with fulvestrant in patients with hormone receptor-positive, HER2-negative metastatic breast cancer. The study is an open-label design, consists of 2 parts: dose-finding portion (Part 1), and expansion portion (Part 2). Both parts include 3 study phases: Screening Phase, Treatment Phase, and Survival Follow-up Phase. The Treatment Phase begins on the day of first dose with study treatment and completes at the Post-Treatment Visit. Approximately, 102 patients will be enrolled in the study.
This was a study to investigate the potential clinical benefit of trilaciclib (G1T28) in preserving the bone marrow and the immune system, and enhancing chemotherapy antitumor efficacy when administered prior to carboplatin and gemcitabine (GC therapy) for participants with metastatic triple negative breast cancer. The study was an open-label and 102 participants were randomly assigned (1:1:1 fashion) to 1 of the 3 following treatment groups: - Group 1: GC therapy (Days 1 and 8 of 21-day cycles) only (n=34) - Group 2: GC therapy (Days 1 and 8) plus trilaciclib (G1T28) on Days 1 and 8 of 21-day cycles (n=33) - Group 3: GC therapy (Days 2 and 9) plus trilaciclib (G1T28) on Days 1, 2, 8, and 9 of 21-day cycles (n=35) The study included 3 study phases: Screening Phase, Treatment Phase, and Survival Follow-up Phase. The Treatment Phase begins on the day of first dose with study treatment and completes at the Post-Treatment Visit.
This is a Phase 2 study to demonstrate the safety and efficacy of SFX-01 when used in combination with aromatase inhibitors (AIs), tamoxifen and fulvestrant. Patients will be enrolled into one of three study arms (SFX-01 in combination with AI, tamoxifen or fulvestrant) based on their current therapy.
The primary goal of this research is to develop and test a web-based genetic education/counseling intervention. This intervention is designed to educate men from hereditary cancer families about the personal relevance of genetic testing in order to help them make decisions about whether to pursue genetic testing. The investigators will test this intervention against standard care for men from hereditary cancer families. The web-based educational intervention includes all of the information typically covered during genetic counseling. As a result, after completing the education intervention participants can proceed directly to genetic testing if they choose. The investigators will conduct a survey prior to randomization and then follow-up surveys at 1-month and 6-months post-randomization. The primary outcome will be uptake of genetic testing. Secondary outcomes will be completion of genetic counseling and decision satisfaction.
The goal of this study is assess the safety and tolerability of the IRX-2 regimen in patients with early stage breast cancer (ESBC) and to estimate the pathologic complete response rate to neoadjuvant anthracycline-based and non-platinum containing chemotherapy in patients with triple-negative breast cancer who have received the IRX-2 Regimen before chemotherapy.
