Filter by:Colon cancer is one of the most lethal malignancies, and colorectal cancer ranks the fifth leading cause of tumor-related mortality in China. FOLFOX is the recommended adjuvant/ neoadjuvant treatment for advanced colon cancer. JS001, as the first Chinese produced anti-PD-1 monoclonal antibody, has been approved by CFDA. This study aims to assess the safety and efficacy of JS001 in combination with FOLFOX as adjuvant/neoadjuvant treatment for patients with locally advanced colon cancer.
Immunomodulating nutrition is supposed to reduce the number of complications and the legnth of the hospital stay during the postoperative period in patients after major gastrointestinal surgery. The aim of the study is to assess the clinical effect of immunomodulating oral nutrition in patients undergoing resection for gastrointestinal cancer in the group of well-nourished patients.
Developement of a clinical and biological database in colon cancer and colic tumors in order to better understand tumor invasion and metastatic scattering processes. The investigators hope that a better understanding of tumoral invasion process will lead to the discovery of new biomarkers and new drugs.
The investigators propose a church-based health promotion program designed to reduce colon cancer risk in a mostly African American community served by the Lincoln Memorial Church in South Los Angeles. The investigators propose involving 20 overweight/obese community members in a 10-session health promotion program featuring weekly cooking classes, didactic nutrition instruction and brief bouts of exercise. Behavioral aim is to increase participants' fiber intake from commonly consumed plant foods and reduce their intake of pro-inflammatory foods. They will be followed for 3 months from time of enrollment. Intervention is expected to increase participants' mean stool weight and improve their Bristol Stool Chart score. Intervention is expected to reduce waist circumference and systolic blood pressure of participants. These effects are expected to be accompanied by self-reports of increased fiber intake and reduced intake of saturated fat and refined sugar as well as evidence of increased physical activity.
Colorectal cancer is a frequent type of cancer accounting for 600,000 deaths annually. Surgical resection remains the best treatment for long-term survival. However, studies suggest that events in the perioperative period can induce metastasis formation and tumor growth. Tumor cells are released into the blood stream during surgery and the surgical stress may create a favorable environment for dissemination of tumor cells into distant tissue. This is done by a cascade of pro-cancerous catecholamines, prostaglandins and cytokines combined with an impaired anti-cancerous cell mediated immune response. Until recently, focus on the anesthetic management of cancer patients has been limited. Relatively small alterations in the perioperative anesthetic management may play a tremendous role in tumor progression. Optimizing anesthesia to reduce the surgical stress response could improve recurrence rates and long-term outcomes for cancer patients by inhibiting perioperative metastasis formation. Regional anesthesia and amide local anesthetics are suspected to calm the immunologic storm of prostaglandins, catecholamines and cytokines when used in the perioperative phase. Furthermore, volatile inhalational anesthesia is thought to modulate the immune system in a pro-cancerous way, while propofol may have opposite effects. Many of these recent studies are statistically underpowered and susceptible to bias, and experts in cancer treatment and anesthesia have emphasized the need for further research within this specific field. In this study the investigators aim to characterize differences in the immunologic response to surgery between inhalational, total intravenous and epidural anesthesia. This will be done by analyzing blood samples obtained in the perioperative period in patients undergoing different modes of anesthesia. The Investigators will furthermore describe the quality of recovery for patients anesthetized with the different methods
A. Background and purpose: Neoadjuvant chemoradiotherapy versus neoadjuvant chemotherapy for unresectable locally advanced colon cancer: an open, multi-centered, randomize controlled phase 3 trial. Colorectal cancer is one of the most common malignant tumors, the morbidity and mortality rate are both in rising trend. 10-23% newly diagnosed colon cancer is at locally advanced stage and surgically unresectable. For this subgroup, treatment guidelines recommend neoadjuvant chemotherapy with or without targeted therapy. However, less than 50% patients could convert into R0 resectable, therapeutic effect is unsatisfactory, 5-year overall survival rate is only 12.5%-45.7%.[JCO,2010] Since 2006, neoadjuvant chemoradiotherapy has been a recommendation as standard treatment for locally advanced rectal cancer, and has been widely applied to clinical use. As for locally advanced colon cancer, it still lacks evidence to support whether neoadjuvant chemoradiotherapy is a beneficial option. There are only several articles about locally advanced colon cancer undertaking neoadjuvant chemoradiotherapy before surgery through Pubmed research, including 3 case reports, 1 abstract and 5 clinical researches with a small sample size, 3 of which are from the investigator's study group. The investigators recently reported clinical data about therapeutic effect of 60 unresectable locally advanced colon cancer cases and the results were exciting. According to the results, through neoadjuvant chemoradiotherapy, R0 resection rate is 86%, local recurrence rate is 10.2%, 3-year OS and 5-year OS are 76.7% and 66.6%, respectively. [Onco Targets Ther, 2018] "Colorectal cancer diagnoses and treatment guidelines" written by Chinses Society of Clinical Oncology (ver. 2017, 2018), suggested that neoadjuvant chemoradiotherapy was an optional treatment strategy or secondary recommended treatment strategy. In a word, the investigators' result was referred as revisory basis of the guideline [CJC,2016], with a relatively low level of evidence in evidence-based medicine. This phase 3 clinical trial mainly aims to acquire a higher level of evidence in evidence-based medicine on the subject about neoadjuvant chemoradiotherapy as a treatment strategy to unresectable locally advanced colon cancer, and the ultimate goal is to rewrite the International treatment guidelines of locally advanced colorectal cancer. B. Research Content: 1. . Research Object: Patients who newly diagnosed unresectable locally advanced colon cancer. Including: 1. tumor infiltrates through the intestinal wall and adheres to tissues and organs around the colon(T4b), imaging assesses that R0 resection is unachievable. 2. Pericolonic lymph node involvement is closely adjacent to the large abdominal vessels, imaging assesses that lymphadenectomy is difficult. 3. Surgical exploration indicates that R0 resection is not achievable. 4. In initial diagnosis, surgeon evaluates the need for extensive multi-organ combined resection and expected to damage the organs, which would seriously affect the postoperative quality of life. 2. . Main research indicator: 5-year overall survival rate 3. . Secondary research indicators: 1. R0 resection rate 2. 3-year tumor-free survival rate 4. . Research groups assignment: 1. Research group: Neoadjuvant chemoradiotherapy group; 2. Control group: Neoadjuvant chemotherapy group. 5. . Sample calculation: Calculation is based on the main research indicator: 5-year survival rate. Based on α=0.05(bilateral), β=0.20(unilateral), 5-year OS improves from 45% in control group to 65% in research group, 4-year period, 5-year follow-up. Research group and control group should at least enroll 74 and 75 qualified cases, respectively, a total of 149 cases, with an expected delisting rate of 20%, the total sample size is 186, 93 cases for each group. 6. . Research protocols: 1. Research group: Neoadjuvant chemoradiotherapy（XELOX * 4 + radiotherapy）→ Surgery (if possible) → post-surgery chemotherapy. 2. Control group: Neoadjuvant chemotherapy（XELOX * 4）→ Surgery (if possible) → post-surgery chemotherapy. Chemotherapy strategy: XELOX: oxaliplatin 130mg/m2, iv drip, d1, every 3 weeks; capecitabine 1,000mg/m2, bid, d1-d14, every 3 weeks. Concurrent chemotherapy: mXELOX: which oxaliplatin is 100mg/m2. Radiotherapy strategy: IMRT, 6-8MV X-ray; GTV 45-50Gy/25F, 1.8-2.0Gy/F; CTV 42.5-45Gy/25F, 1.7-1.8Gy/F; Actual delivery dose should be adjusted according to max tolerance dose of organs at risk, but the delivery dose of GTV and CTV must within the required range. Surgery: Reexamination is performed 5 weeks after radiotherapy for research group and 2 weeks after the fourth period of chemotherapy, surgery is performed in 6-12 weeks after neoadjuvant treatment.
Background: 1. . The incidence and mortality of colon cancer are high in China and in the world. 2. . The treatment of many patients in the real world is not standardized, and there are problems such as over-treatment or under-treatment. To explore the adjuvant treatment of colon cancer in the Chinese population, this study will retrospectively analyze real-world data on adjuvant therapy for colon cancer in Chinese patients after radical surgery. The purpose of research: 1. . Current status of adjuvant therapy for stage II-III colon cancer in the real world: chemotherapy regimen, chemotherapy time, efficacy, safety, etc. 2. . Comparison of efficacy and safety of different adjuvant chemotherapy time (<3 months vs. >=3 months) in high-risk stage II and III colon cancer patients in the real world 3. . Comparison of efficacy and safety of different adjuvant chemotherapy regimens (XELOX vs. FOLFOX) in high-risk stage II and III colon cancer patients in the real world
Adaptated Physical Activity (APA) during treatment of cancer is one of the actual global health recommendation because of the benefits observed in several parameters evaluated in many clinical studies. A best knowledge of the physical and medical characteristics of patients, including type of cancer and type of treatment, is primordial to optimize the patient care and the effectiveness of APA programs. Descriptive, explorative and prospective study of 3 different populations: One population with locally advanced or metastatic non-small cell lung cancer treated with multiple therapeutic lines. Two different populations of early cancer patients and treated with a platinum-based regimen for colon cancer and a taxane-based chemotherapy for breast cancer.
This proposal seeks to further understand the contribution of the PIK3CA mutations in colon cancer, by correlating the type of hotspot mutation with the development of metastases in stage II and stage Ill patients. In order to do this, DNA will be extracted from either frozen or paraffin embedded colon cancer tissues to sequence PIK3CA, KRAS and BRAF. Clinical outcome data will be gathered to include metastases and survival to correlate with PIK3CA, KRAS and BRAF mutational status. Patients with stage II and stage Ill colon cancers will be identified in the University of New Mexico Human Tissue Repository and the NIH PLCO prevention trial biorepository. Existing banked tissues of stage II and Ill colon cancers will be collected. There will be no direct contact with living individuals. Epidemiological factors such as age, race, gender and outcome data of metastases and survival will be collected.
61 subjects (male or female) between the ages of 45 and 75 will undergo colonoscopy. The primary outcome is Cecal Intubation
