Active clinical trials for "Rectal Neoplasms"

The purpose of this study is to evaluate the safety and efficacy of irreversible electroporation (IRE) for unresectable Rectal Neoplasms.

This phase I/II trial studies the side effects and best dose of nintedanib when given together with capecitabine and to see how well they work in treating patients with colorectal cancer that has not responded to previous treatment (refractory) and has spread to other places in the body (metastatic). Nintedanib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It may also block the growth of new blood vessels necessary for tumor growth. Drugs used in chemotherapy, such as capecitabine, 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. Giving nintedanib with capecitabine may be a better treatment for colorectal cancer.

INTRODUCTION: Transanal TME (T-TME) combined with laparoscopy, called hybrid-NOTES, is a less invasive procedure that responds to some of the limitations of the rectal laparoscopic approach. MAIN OBJECTIVE: To analyze that the T-TME gets a faster recovery due to a lower conversion rate to open surgery than laparoscopic low anterior resection (L-LAR) in rectal cancer with the same pathological, functional and oncologic results. METHODOLOGY: A prospective multicenter randomized controlled study of patients with rectal cancer that, were randomized in the T-TME- and L-LAR group. The main variables are: general morbidity, anastomotic dehiscence, conversion rate to open surgery and hospital stay. The sample calculation is 58 patients per group.

The purpose of the study is to compare pre-operative radio-chemotherapy (RT + capecitabine) to a short course RT associated with a delayed surgery, with two primary objectives: the efficacy evaluation (rate of R0 resection) and the preservation of autonomy (score IADL).

The purpose of this study is to compare two different surgical procedures for the treatment of Rectal Cancer: Laparoscopic Surgery and Robotic Assisted Laparoscopic Surgery. The ROLARR study is for participants with cancer of the rectum for whom a laparoscopic operation (sometimes called "keyhole surgery") has been recommended by their surgeon. In the past most rectal cancers were removed using "open" surgery. Open surgery involves a large cut down the middle of the patient's abdomen to allow the surgeon to see and take out the cancer. On a previous study showed that using laparoscopic surgery to remove colorectal cancers was as good as open surgery for curing cancer. There is now another option to remove rectal cancers, which involves using a robotic system with laparoscopic surgery. This type of surgery is called "robotic-assisted" laparoscopic surgery and is now becoming widely used by surgeons to remove cancers including the rectum, as well as for other non-cancer operations. In order to perform robotic-assisted laparoscopic surgery, the surgeon sits at a robotic control unit a few feet away from the patient. Using the robotic control unit, the surgeon can see a clear video image of the patient's abdomen and the operation site. The surgeon can perform the operation from the robotic control unit by controlling the movement of a set of robotic surgical instruments, guided by the video camera. Like standard laparoscopic surgery, the surgeon is able to carry out the entire operation through a few small cuts in the abdomen. The camera of the robotic system provides a 3D high-definition magnified view of the operation site and the robotic system is also able to translate the movements of the surgeon's hands into small precise movements inside the patient's body. We want to test whether robotic-assisted laparoscopic surgery is as good, or even better, at removing rectal cancers as standard laparoscopic surgery (actually Robotic-assisted laparoscopic surgery is used as standard of care in rectal cancer patients at University of California, Irvine Medical Center). We also want to investigate whether using robotic-assisted laparoscopic surgery reduces the number of times a laparoscopic operation needs to be converted to an open operation, and see whether using a robotic system can also shorten the length of time patients need to stay in hospital and if it reduces the number of complications patients may have during and after their operation.

safety evaluation of endoscopic sub-mucosal dissection with nestis enki2 system. This system is a new water jet system which allows to perform Endoscopic submucosal dissection with a bifunctional catheter (injection and cutting).

This phase I trial studies the side effects and best dose of MEK inhibitor MEK162 when given together with leucovorin calcium, fluorouracil, and oxaliplatin in treating patients with advanced metastatic colorectal cancer. MEK inhibitor MEK162 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving MEK inhibitor MEK162 with leucovorin calcium, fluorouracil, and oxaliplatin may kill more tumor cells.

This study is being done to determine the dose of a chemotherapy drug (irinotecan [irinotecan hydrochloride]) that can be tolerated as part of a combination of drugs. There is a combination of chemotherapy drugs often used to treat gastrointestinal cancer, which consists of 5-FU (fluorouracil), leucovorin (leucovorin calcium), irinotecan and oxaliplatin and is known as "FOLFIRINOX". FOLFIRINOX is a current drug therapy combination (or regimen) used for people with advanced pancreatic cancer, although this combination is not Food and Drug Administration (FDA) approved for this indication. FOLFIRINOX was recently shown in a separate clinical trial to increase survival compared to another commonly used drug in pancreatic cancer called gemcitabine. FOLFIRINOX is also a reasonable regimen for those with other advanced cancers of the gastrointestinal tract, including colon cancer, rectal cancer, esophagus cancer, stomach cancer, gall bladder cancer, bile duct cancer, ampullary cancer, and cancers with an unknown primary location. The best dose of irinotecan to use in FOLFIRINOX is not known. This study will analyze one gene (uridine 5'-diphospho [UDP] glucuronosyltransferase 1 family, polypeptide A1 [UGT1A1] gene) of subjects for the presence of an alteration in that gene, which may affect how the body handles irinotecan. Genes help determine some of the investigators individual characteristics, such as eye color, height and skin tone. Genes may also determine why people get certain diseases and how medicines may affect them. The result of the genetic analysis will divide subjects into one of three groups: A, B, or C. Group A (approximately 45% of subjects) will receive the standard dose of irinotecan. Group B (approximately 45% of subjects) will receive a lower dose of irinotecan. Group C (approximately 10% of subjects) will receive an even lower dose of irinotecan

A randomized two-arm study comparing preoperative CRT using oral capecitabine versus bolus 5-FU/LV concomitant to external beam radiation (50.5 Gy/28 fractions) for locally advanced rectal cancer. Main outcome was clinical response assessed using MRI and endorectal US 6-8 weeks after CRT. Secondary endpoints were pathological response, adverse effects, sphyncter preservation, quality of life, OS and DFS.

Open-label, Phase I-II, first-in-human (FIH) study for A166 monotherapy in HER2-expressing or amplified patients who progressed on or did not respond to available standard therapies. Patients must have documented HER2 expression or amplification. The patient must have exhausted available standard therapies. Patients will receive study drug as a single IV infusion. Cycles will continue until disease progression or unacceptable toxicity.
