Filter by:Background: Colorectal cancer is a common cancer in the Unites States (U.S.) It causes the second most cancer-related deaths. The drug avelumab and vaccine Ad-CEA together help the immune system fight cancer. Objective: To test if avelumab and Ad-CEA plus standard therapy treats colorectal cancer that has spread to other sites better than standard therapy alone. Eligibility: People ages 18 and older with untreated colorectal cancer that has spread in the body Design: Participants will be screened with: Test to see if their cancer has a certain deficiency Blood, urine, and heart tests Scans Medical history Physical exam Tumor sample. This can be from a previous procedure. A small group of participants will get Ad-CEA and avelumab plus standard therapy. This is leucovorin calcium (folinic acid), fluorouracil, and oxaliplatin (FOLFOX) plus bevacizumab for up to 24 weeks then capecitabine plus bevacizumab. The others will have treatment in 2-week cycles. They will be Arm A or B: Arm A: FOLFOX and bevacizumab by intravenous (IV) days 1 and 2 for 12 cycles. After that, capecitabine by mouth twice a day and bevacizumab by IV on day 1. Arm B: Ad-CEA injection every 2-12 weeks. Avelumab by IV on day 1 of each cycle. FOLFOX and bevacizumab by IV days 2 and 3 for 12 cycles. Then, capecitabine by mouth twice a day and bevacizumab through IV on day 2. Participants will repeat screening tests during the study. Participants will be treated until their disease gets worse or they have bad side effects. Arm A participants can join Arm B. They will have a visit 4 5 weeks after they stop therapy.
Background: Combinations of Dendritic and Cytokine-induced Killer Cells (DC-CIK) and Cytokine-induced Killer Cells (CIK) treatment may enhance the immune response and stop cancer cells from growing. The investigators suppose that DC-CIK combined with CIK treatment will improve the prognosis of advanced solid tumors. Objective: Phase II clinical trial to investigate the efficacy of concurrent chemotherapy with DC-CIK and CIK treatment in patients with treatment-refractory solid tumors. Study treatment: Patients in group A will receive 4 cycles of CIK treatments and 4 cycles of DC-CIK treatments within 8 months. Patients in group B will have no immunotherapy . chemotherapy are available in both groups.
This is a multicenter, open-label, Phase 1 study of SC-006 given as a single agent and in combination with ABBV-181 in participants with advanced colorectal cancer (CRC), and consists of Part A (single agent SC-006 dose regimen finding), followed by Part B (single agent SC-006 dose expansion), and Part C (SC-006 and ABBV-181 combination escalation and expansion). Part A (dose regimen finding) will involve dose escalation and possible dose interval modification to define the maximum tolerated dose (MTD) and/or recommended Part B dose and schedule. Part B (dose expansion) will enroll additional participants who will be treated with a study drug dose at or below the MTD determined in Part A. Part C is dose escalation of SC-006 and fixed dose of ABBV-181 in combination. Recommended dose cohort of SC-006 with ABBV-181 will be expanded.
Retrospective analysis on colonoscopies in the endoscopy unit of the Lyell McEwin Hospital.
Patient age 45 year old and above who presented with rectal bleeding at three tertiary hospitals in South West Nigeria were invited for colonoscopy. The clinical information of the patients and the colonoscopy data were analyzed
The goal of the project is to increase colorectal cancer screening within the priority population of female and male adults age 50 to 85 in Northern Nevada. A successful community-based cancer patient navigator program will be modified in partnership with the community into a multi-level screening intervention.
At present, chemotherapy is widely used in the adjuvant treatment of colorectal cancer patients after surgery. Capecitabine is one of the main chemotherapeutic drugs. But the effect is not good enough, the adverse reaction is serious, and the individual differences were significant. The present study shows that these problems are related to the differences in the exposure of capecitabine and its metabolites in different patients. The genetic biomarkers for capecitabine include DRD, MTHFR and TYMS. Mutations in these genes directly affect the expression of metabolic enzymes involved in capecitabine and control the concentration of capecitabine and its metabolites. However, these markers have been obtained through clinical trials in the United States, and their role in predicting the effectiveness or safety of capecitabine and its metabolites has not been validated in Chinese cancer patients.The study was based on a case study of patients with colorectal cancer in China, and capecitabine as the primary postoperative chemotherapy regimen to verify whether the available biomarkers can be used to predict the effectiveness and safety of capecitabine. To clarify the effect of capecitabine on endogenous metabolites, and to study the mechanism of its effect, so as to discover new biomarkers.
This is a two part observational study evaluating the feasibility of implementing an EHR-based model within a community oncology practice.
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
Worldwide, nearly 1.25 million patients are diagnosed with and more than 600,000 patients die from colorectal cancer each year. The third leading cause of death is colorectal cancer in Taiwan 2012. The current treatments for colorectal cancer including surgery, chemotherapy and/or radiotherapy are prescribed to improve survival and lower the risk of recurrence. However, disease and treatment-related toxicities in cancer patients may result in fatigue and interfered quality of life (QoL). Previous studies have reported that cancer-related fatigue (CRF) is the most common symptom experienced by patients at all stage of diseases, it can occur during treatment, in advanced disease and in disease-free survivors; the prevalence of fatigue is reported to be between 59-96% in patients undergoing chemotherapy, 65-100% in patients receiving radiation therapy, and 30% in long term survivors. Also, CRF has been reported as the most frequent and distressing toxicity of colon and rectal chemotherapy. The National Comprehensive Cancer Network (NCCN) has published guidelines for the definition of CRF as ''a persistent subjective sense of physical, emotional, and/or cognitive tiredness or exhaustion related to cancer or cancer treatment that is not proportional to recent activity and that significantly interferes with usual functioning." Besides, CRF could dynamically change with the interactions among disease progression, treatment regimen, tumor site, nutrition, infection or other factors. Therefore, to minimize the impact of CRF on cancer patients, more in-depth researches on CRF are needed. The aim of this longitudinal study is to examine the dynamic changes, correlated factors and QoL of CRF among colorectal cancer patients during adjuvant chemotherapy. Furthermore, the results will supply physicians with more understanding about CRF, and help them to enhance the quality on cancer care to being perfected in the future.
