Filter by:Mucositis is a common and clinically significant side effect of both anticancer chemotherapy and radiation therapy that can affect any portion of the gastrointestinal tract. Not only associated with an adverse symptom profile, but also it may limit patients' ability to tolerate treatment if not adequately prevented and managed. Moreover, it may be associated with secondary local and systemic infection and poor health outcomes, and generates additional use of healthcare resources resulting in additional costs. Based on study of 38 patients of mean age sixty-one years old diagnosed with colorectal carcinoma were included to evaluate gastrointestinal adverse effect with different schedules of FOLFOX. Incidence of oral mucositis with FOLFOX-4 Is 76%, FOLFOX-6 is 62%, mFOLFOX-6 is 79% and FOLFOX-7 is 93% Chemotherapy-induced mucositis is commonly described as a five-phase sequence: initiation (0-2 days),upregulation and activation of messengers (2-3 days), signal amplification (2-5 days), ulceration with inflammation (5-14 days) and healing (14-21 days) According to the model introduced by some studies the primary inducer involved in unleashing mucosal injury upon chemotherapy is the production of reactive oxygen species (ROS), leading to tissue inflammation and mucositis induction. Inflammatory signaling pathways are upregulated during high reactive oxygen species states which further contribute to cytotoxicity. leading to the third step in the oral mucositis pathway. In this inflammatory phase, cytokines including Tissue Necrosis Factor alpha (TNF-α), prostaglandins, Nuclear factor Kappa β (NF-кβ), and interleukin (IL) 1β are released. The cytotoxic effects of chemotherapy, inflammation, and reactive oxygen species-mediated DNA damage result in gradual apoptosis of mucosal epithelial cells. Ulcerative sites become relatively neutropenic which predisposes them to bacterial and yeast infections. These bacterial toxins further simulate the underlying inflammatory state through release of additional cytokines. It is necessary to emphasize that oral mucositis is frequently documented only in its advanced phases owing to the requirements for clinical therapy and assistance. Therefore, the search for new active ingredients that could be used in the prevention (and even treatment) of oral and intestinal mucositis is of utmost importance.
Cross-sectional study. Data on clinical, anthropometric, biochemical profile and dietary intake Upper Gastrointestinal Cancer Patients upon admission are traced and collected.
The aim of this study is to describe the outcomes in American Indian patients receiving immunotherapy in a multi-institution retrospective study at several other high-volume centers that care for this patient population and to identify any healthcare disparities that can lead to future interventional studies.
Cachexia is a common complication of various advanced malignant tumors, which seriously affects the quality of life and survival time of patients. In view of the clinical problem of non-nutritional response in patients with cachexia, the investigators plan to carry out a clinical case-control study on the intervention of creatine combined with curcumin in participants with cachexia. On the whole, the investigators limited the study subjects to upper digestive tract tumors and diagnosed participants with early cachexia. The main purpose of this study is to determine whether the combination of the two can play a positive and stable role in inhibiting the inflammation of cachexia and improving metabolic status, so that basic nutrition can play a role, in order to reduce the level of skeletal muscle consumption, maintain weight, improve quality of life, save medical costs and extend survival time.
To find a recommended dose of the combination of adagrasib and durvalumab that can be given to patients with cancers that have a KRAS G12C mutation.
This is an international, prospective study to assess the impact of concomitant early use of liquid biopsy (FoundationOne® Liquid CDx) within the diagnostic pathway, compared with the standard of care diagnostic pathway, on the timing of routine cancer care in treatment-naïve participants presenting with a clinical diagnosis of advanced cancer, where the pathologic diagnosis has not yet been confirmed. Participants with one of the following two clinical presentations will be included: participants with evidence of de novo metastatic lung cancer or participants with evidence of de novo metastatic gastrointestinal cancer. Participants may have undergone different levels of diagnostic workup prior to enrollment. Participants who have not had tissue biopsy performed prior to enrollment will be classified as 'basic workup' and those who have had tissue biopsy performed prior to enrollment will be classified as 'extended workup'. During the diagnosis period, eligible participants will undergo liquid biopsy (FoundationOne® Liquid CDx assay; as per label) on blood samples. Blood samples will be tested using the FoundationOne® Liquid CDx assay at a central laboratory. In parallel, participants will undergo the standard of care diagnostic pathway, including tissue biopsy and histology workup, if not already done before enrollment, and molecular workup according to ESMO guidelines or national guidelines for each tumor type included in this study. Once a complete pathologic diagnosis has been made, the investigator (or multidisciplinary team) can complete an anti-cancer treatment recommendation assessment. Anti-cancer treatment recommendation should follow current practice and professional guidelines based on the results provided by either liquid biopsy (as per label) or tissue biopsy/standard of care.
The purpose of this study is to find out whether lattice radiation therapy (LRT) is an effective radiation therapy technique when compared to standard stereotactic body radiation therapy (SBRT). The study will also study how the different radiation therapy techniques (LRT and SBRT) affect how many immune cells are able to attack and kill tumor cells (immune infiltration).
This study examines the feasibility and acceptability of a virtual tumor board for cancer and mental illness for patients with serious mental illness and a new cancer diagnosis. The study also examines the impact on patient care, psychiatric symptoms, and clinician self-efficacy in managing this population.
A spectroscopic probe is a sensor designed to illuminate and gather light directly from the tissue while touching it. The probe contains optical fibres, some which illuminate the surface of the tissue with harmless visible (white) light, and others that collects the light that has been reflected from inside the tissue. As the investigators track the position of the probe, they can create spectroscopic images with richer colour information, allowing surgeons to differentiate between different types of tissue, such as normal or cancerous regions. The spectroscopic probe, either sterilised or covered with a sterile probe cover, will be used on the tissue as part of the patient's operation, inside the body itself. The tissue will be sampled using the spectroscopic probe before the surgeons remove the tissue from the body. The research team will be in the operating theatre. The surgeon or a member of the research team will use the optical probe on the tissue samples. This will involve taking pictures and videos of the sample while the research team scan the samples with the spectroscopic probe.
Surgery is often a central curative treatment for gastrointestinal tumors. Surgical treatment of diagnosed cancer tumors is decided after a comprehensive assessment of the patient's physical status, radiological assessments and after careful evaluation at the multidisciplinary conference. Despite the careful preoperative assessment of patients for curative surgery, the planned operation may unexpectedly need to be canceled. Of the patients who were planned for curative resection for pancreatic cancer in 2021 in Sweden, 90% received the intended surgery, and 10% of planned surgery was canceled. The reason for this was disseminated cancer or locally advanced disease in which radical resection is considered impossible to carry out. A systematic review of knowledge reveals a significant lack of evidence regarding patient-centered research and aborted cancer surgery. The studies in the project have different study designs and methods, and include focus group interviews with staff, translation and validation of a questionnaire to measure care needs, estimation of supportive care needs and patient experiences. An improved understanding and knowledge of patients' preferences and needs is needed to design interventions that can improve health-related quality of life. This project is dedicated to studying patients undergoing aborted cancer surgery, with the aim of improving the quality of care and meeting patients' care needs.
