NCT ID: NCT03809403 Not yet recruiting - Colorectal Cancer Clinical Trials

Influence of the Surgical Technique Used for Colectomies on the Concentration of Circulating Tumor DNA and the Presence of Circulating Tumor Cells: Comparison of the "no Touch" Technic With Either First Clamping of the Mesenteric Vessels or First Mobilization of the Tumor Followed by Clamping.

Start date: January 2019
Study type: Observational

Colectomy is the most commonly used therapeutic approach for the treatment of non-metastatic colorectal cancer. This approach is generally very effective however the rate of recurrence and the appearance of metachronous metastasis remains a major problem in the postoperative period. One of the hypothesis that can explain this tumor progression is the dissemination of tumor cells at the time of tumor mobilization. In this work, we wish to verify this hypothesis by comparing two surgical technics used in our department for left or right colectomies: respectively either first section of the mesenteric vessels followed by the mobilization of the tumor or first mobilization of the tumor followed by the section of the mesenteric vessels. To evaluate the dissemination, we will study two disseminations markers that have shown their prognostic value: i) circulating tumor cells (which represent a direct marker of dissemination) and ii) tumor circulating DNA (which is an indirect marker) but has the advantage of being more representative of all tumor clones and therefore the tumor burden released into the blood at the time of surgery).

To evaluate the feasibility and precision of stereotaxic navigation in laparoscopic surgery for colorectal cancer.

NCT ID: NCT03803891 Recruiting - Colorectal Cancer Clinical Trials

Endoscopic Full-Thickness Resection In Colon

Start date: May 1, 2018
Study type: Observational [Patient Registry]

Endoscopic full-thickness resection (EFTR) in the colon using an over-the-scope clip (OTSC) as a closure mechanism is a recent technique that allows the endoscopic resection of colonic lesions that are poor candidates for conventional endoscopic resection techniques. The aim is to study the safety and efficacy of EFTR in colon.

NCT ID: NCT03803267 Not yet recruiting - Colorectal Cancer Clinical Trials

Analgesia of Erector Spinae Plane Block Versus Quadratus Lumborum Block

Start date: May 1, 2019
Phase: N/A
Study type: Interventional

Colorectal cancer is the third most common cancer worldwide. These patients usually undergo open surgical resection of cancer under general anaesthesia. The aim of this study is to detect whether the Erector spinae plan block or Quadratus lumborum block will provide the most ideal analgesia for these patients. Erector spinae plan block is a novel analgesic technique that provides both visceral and somatic analgesia due to its communication with the paravertebral space. Quadratus lumborum block is a truncal nerve block usually used for intra-abdominal surgeries. Ultrasound guidance increases the accuracy and safety of both techniques. A local anaesthetic mixture of Bupivacaine 0.25% and dexamethasone will be used for both techniques.

NCT ID: NCT03803241 Recruiting - Colorectal Cancer Clinical Trials

Cd133+ Cell Infusion in Patients With Colorectal Liver Metastases.

Start date: May 2015
Phase: Phase 2
Study type: Interventional

Treatment of patients with metastatic colorectal carcinoma is surgical resection. Only 10-15% of the patients will be candidates for curative resection. After response to chemotherapy this figure rises 10-13% more. To perform the surgery it is necessary to have a sufficient remnant liver volume (RLV), which allows maintaining optimal liver function after resection. If the estimated RLV is insufficient preoperatively, portal venous embolization site (PVE) is performed for compensatory hypertrophy, thus increasing the number of resections 19%. Still, in 20% of these patients surgery can not be performed because RLV is not achieved or because the disease progresses while waiting for growth. Therefore, it is necessary to improve liver regeneration without promoting tumor growth. Studies on liver regeneration, have determined that cells (CD133 +) are involved in the liver hypertrophy that occurs after hepatectomy. CD133 + have been used to induce liver hypertrophy with encouraging results. This population of CD133 +, can be selected from peripheral blood after stimulation with Granulocyte colony-stimulating factor (G-CSF), being able to obtain a large number of them. The investigators propose to treat patients who do not meet criteria for surgery because of insufficient volume <40%, with CD133 + and portal embolization in order to carry out a surgical resection in a second place.

NCT ID: NCT03802747 Not yet recruiting - Colorectal Cancer Clinical Trials

Immunotherapy Combined With Y-90 and SBRT for Colorectal Liver Metastases

Start date: March 2019
Phase: Phase 1
Study type: Interventional

This study is evaluating the combination of Y-90 radioembolization followed by SBRT with the immunotherapy drugs, durvalumab and tremelimumab, to improve disease control of liver metastases for patients with microsatellite stable colorectal cancer.

NCT ID: NCT03799731 Recruiting - Colorectal Cancer Clinical Trials

Study for Evaluation of GM102 Anti-tumoral Activity in Colorectal Cancers

Start date: July 11, 2018
Phase: Phase 2
Study type: Interventional

Phase 2A study, assessing the antitumor activity and the safety profile of GM102, a new compound (monoclonal antibody), administered alone or in combination with chemotherapy in patients with locally advanced or metastatic colorectal cancer. The primary objective of the study is to evaluate the antitumor activity of GM102 single agent and in combination with trifluridine/tipiracil.

NCT ID: NCT03798626 Not yet recruiting - Colorectal Cancer Clinical Trials

Gevokizumab With Standard of Care Anti-cancer Therapies for Metastatic Colorectal, Gastroesophageal, and Renal Cancers

Start date: March 12, 2019
Phase: Phase 1
Study type: Interventional

This study will determine the pharmacodynamically-active dose of gevokizumab and the tolerable dose and preliminary efficacy of gevokizumab in combination with the standard of care anti-cancer therapy in patients with metastatic colorectal cancer, metastatic gastroesophageal cancer and metastatic renal cell carcinoma.

NCT ID: NCT03797326 Not yet recruiting - Colorectal Cancer Clinical Trials

Efficacy and Safety of Pembrolizumab (MK-3475) Plus Lenvatinib (E7080/MK-7902) in Previously Treated Participants With Select Solid Tumors (MK-7902-005/E7080-G000-224/LEAP-005)

Start date: February 13, 2019
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine the safety and efficacy of combination therapy with pembrolizumab (MK-3475) and lenvatinib (E7080/MK-7902) in participants with triple negative breast cancer (TNBC), ovarian cancer, gastric cancer, colorectal cancer (CRC), glioblastoma (GBM), or biliary tract cancers (BTC). Participants will be enrolled into initial tumor-specific cohorts which will be expanded if adequate efficacy is determined.

NCT ID: NCT03795311 Recruiting - Colorectal Cancer Clinical Trials

Evaluation of the Efficacy and the Safety of FOLFIRINOX3 Bevacizumab Treatment in Patients With Colorectal Cancer (FOLFIRINOX 3)

Start date: October 11, 2018
Phase: Phase 1/Phase 2
Study type: Interventional

In patients in progression after oxaliplatin and irinotecan, the study FOLFIRINOX 3 proposes to evaluate the interest of modifying the standard pattern of administration of the molecule of irinotecan in order to make it more efficient. In combination with other chemotherapy drugs (5-fluorouracil, oxaliplatin, folinic acid and bevacizumab), irinotecan will be administered at the beginning and end of each cycle of chemotherapy, whereas it is normally administered at one time in the regimen. standard of treatment. The hypothesis of this study is an increase in the objective response rate at 2 months of 10 to 30% with a scheme by FOLFIRINOX3 - bevacizumab compared to an optimal treatment to date by FOLFIRINOX-bevacizumab.
