Active clinical trials for "Colonic Neoplasms"

The aim of this randomized double-blinded placebo-controlled phase 2 study is to determine efficacy of preoperative treatment with interferon-alfa2a in patients with pMMR colon cancer on perioperative immune suppression and infiltration of lymphocytes in the primary tumor.

This phase Ib/II trial studies the side effects and best dose of SX-682 that can be given alone and in combination with nivolumab in treating patients with RAS-Mutated, microsatellite stable (MSS) colorectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). SX-682 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving SX-682 alone and together with nivolumab may kill more tumor cells.

To compare the efficacy of FOLFOXIRI plus Cetuximab and FOLFOXIRI plus Bevacuzumab in the conversion therapy of right-sided colon cancer liver metastases

RATIONALE: Recently, the importance of prognosis according to the location of the primary tumor in colorectal cancer has been raised. In the CALGB / SWOG 80405 study published in 2016, the addition of bevacizumab or cetuximab to the first line FOLFIRI / FOLFOX in KRAS (codon 12, 13) wild type metastatic colorectal cancer (mCRC) patients did not show a significant difference between overall survival (OS) and progression free survival (PFS) in both groups. Alan P. Venook et al. published a follow-up subgroup analysis on the effect of primary tumor location at 2016 ASCO. In the treatment group with cetuximab, the difference in treatment effect was significant according to the primary tumor location. The right colon cancer showed a poor prognosis for cetuximab treatment. (PFS: 7.8 vs 12.4 months, HR 1.56, p <0.0001 / OS: 16.7 vs 36.0months, HR 1.87, P <0.0001). Therefore, the investigators propose a phase II trial for the efficacy evaluation of bevacizumab-FOLFOXIRI and bevacizumab-FOLFIRI or FOLFOX treatment in patients with poor prognosis of unresectable right-sided colorectal cancer.

The purpose of this study is to design a prospective randomized clinical trial to explore whether postoperative adjuvant chemotherapy may provide survival benefit for stage II colon cancer patients with high risk factors.Therefore the investigators can provide high level clinical evidence of indications for patients with colon cancer with stage II colon cancer.

Four retrospective studies were recently published on efficacy of aspirin in patients with surgically resected colon cancer. Two of these studies strongly suggested that aspirin used in low doses (100 mg/d) after surgical resection of colorectal cancer with PI3K mutation could act as a targeted therapy with a major protective effect on the risk of recurrence. The other two studies did not confirm the benefit of aspirin in this situation. These four retrospective studies provide an insufficient level of evidence to demonstrate the benefit of low-dose aspirin as adjuvant to surgery for colorectal cancer. Therefore, it is necessary as recommended in the conclusion of these studies and meta-analyses to perform a randomised prospective study to validate these data.

The aim of this trial is to evaluate the value of palliative primary tumor resection in colon cancer patients with initially unresectable metastases and a positive response to induction chemotherapy which depends on gene testing. The primary endpoint is to evaluate overall survival.

This is a prospective, single arm study to assess the safety and performance of the EndoMaster EASE (Endoluminal Access Surgical Efficacy) System for the treatment of patients with colorectal neoplasms.

This early phase I trial studies how well heated intra-peritoneal chemotherapy with doxorubicin and cisplatin work for the treatment of abdominal or pelvic tumors that can be removed by surgery (resectable), does not respond to treatment (refractory), or has come back (recurrent). Heated intra-peritoneal chemotherapy is a procedure performed in combination with abdominal surgery for cancer that has spread to the abdomen. It involves the infusion of a heated chemotherapy solution that circulates into the abdominal cavity. Chemotherapy drugs, such as doxorubicin and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Heating a chemotherapy solution and infusing it directly into the abdomen may kill more cells.

The dose escalation phase of this trial identifies the best dose and safety of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
