Active clinical trials for "Colonic Neoplasms"

Current therapies for metastatic or unresectable Colon Cancer provide very limited benefit to the patient. The anti-cancer properties of Antineoplaston therapy suggest that it may prove beneficial in the treatment of metastatic or unresectable Colon Cancer. PURPOSE: This study is being performed to determine the effects (good and bad) that Antineoplaston therapy has on patients with metastatic or unresectable Colon Cancer

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: . 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. . Main research indicator: 5-year overall survival rate . Secondary research indicators: 1. R0 resection rate 2. 3-year tumor-free survival rate . Research groups assignment: 1. Research group: Neoadjuvant chemoradiotherapy group; 2. Control group: Neoadjuvant chemotherapy group. . 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. . 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.

The purpose of this study is to determine if dMMR and/or POLE exonuclease domain mutant stage III colon cancer patients gain clinical benefit (i.e. improvement in disease free and overall survival) from PD-L1 inhibitors after standard fluoropyrimidine-based adjuvant chemotherapy. Avelumab binds PD-L1 and blocks the interaction between PD-L1 and PD-1. This removes the suppressive effects of PD-L1 on anti-tumour CD8+ T cells, resulting in the restoration of cytotoxic T cell response. The rationale of giving Avelumab after standard adjuvant chemotherapy to this well-defined, molecularly-selected, group is based on the fact that dMMR and POLE exonuclease domain mutant CRCs have a highly and ultra-mutated genetic profile, respectively, thus leading to a high number of neo-antigens with associated over expression of immune checkpoint related proteins. This profile is expected to be highly responsive to checkpoint inhibition as suggested by data of PD-1 inhibitors in dMMR/MSI-H metastatic CRCs. If this study meets the primary endpoint, using Avelumab in the adjuvant setting following standard chemotherapy would become the standard of care for patients with dMMR and/or POLE exonuclease domain mutant colon cancers. Furthermore, given the availability of molecular markers for patient selection, funders of healthcare would be more likely to fund this treatment. This study also provides a unique opportunity to conduct translational research analyses on pre- and post-treatment tumour tissue samples and blood samples from dMMR or POLE mutant CRC patients treated with the checkpoint inhibitor Avelumab.

An enhanced recovery program has been developed to provide for colon cancer patients faster and more personalized postoperative treatment. Most of the previous studies have showed that the efficacy of the enhanced recovery program on both subjective and objective physical recovery of patients. However, such studies are rarely conducted in South Korea. The purpose of this study is to evaluate the feasibility and efficacy of a postoperative enhanced recovery program in patients who underwent laparoscopic colon cancer surgery at a tertiary hospital in Korea.

Different subtypes of serrated lesions have been recently described. Among them, both sessile serrated polyp/adenoma (SSP/A) and traditional serrated adenoma (TSA) could have malignant potential through the serrated pathway or CIMP. These lesions, as a potential source of interval cancer, should also be considered in colorectal cancer (CRC) population-based screening programs. It is believed that this new described pathway could be responsible for up to 30% of all CRC. Unlike the traditional adenoma, serrated lesions are difficult to diagnose because of their particular endoscopic appearance and their still unclear histological criteria. Furthermore, they have specific molecular changes and, through them, they could evolve into CRC faster than the adenoma. The real prevalence of the serrated lesions and their specific risk for developing new synchronous/metachronous lesions, or even malignancy, remains unknown. For all these reasons, we don't know if these patients could constitute a different CRC-risk group and if specific recommendations are needed during their follow-up. This is a prospective longitudinal study developed within the framework of the CRC-screening program in the Valencian Community (Spain). We expect to include a total of 700 individuals who will be followed during 10 years. In our study, we will collect epidemiologic variables related to the patient, variables related to all the polyps, and mutational (BRAF, KRAS, MSI), and CpG-island methylation status of serrated lesions. Strict endoscopic and histological criteria will be applied for the diagnosis of serrated lesions. All lesions detected at the index colonoscopy and during follow-up will be evaluated. The purpose of this study is to correlate epidemiologic data, histological characteristics and the molecular profile of the serrated lesions with findings during follow-up, in order to define stratified groups according to their risk of developing new lesions or CRC in the future.

This randomized pilot clinical trial studies health care coach support in reducing acute care use and cost in patients with cancer. Health care coach support may help cancer patients to make decisions about their care that matches what is important to them with symptom management.

Panobinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin calcium, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving panobinostat together with fluorouracil and leucovorin calcium may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and the best dose of giving panobinostat, fluorouracil, and leucovorin calcium together in treating patients with stage IV colorectal cancer who did not respond to previous fluorouracil-based chemotherapy.

RATIONALE: Lenalidomide may stop the growth of tumor cells by blocking blood flow to the tumor. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving lenalidomide together with cetuximab may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of lenalidomide when given together with cetuximab in treating patients with metastatic colorectal cancer.

This is a Phase I study; dose escalating the combination of pazopanib when taken daily and ixabepilone when administered on day 1 of a 3 week treatment course.

RATIONALE: Diagnostic procedures that look for micrometastases in lymph nodes removed during surgery for colon cancer may help doctors learn the extent of disease. PURPOSE: This phase I trial is studying lymph nodes in patients with stage II colon cancer.
