RECTAL ADENOCARCINOMA

This study looks at whether a combination of radiation and chemotherapy can cure low rectal cancer, allowing patients to avoid surgery. About 108 people with early-stage rectal tumors near the anus will receive this treatment. The main goal is to see if the cancer stays under con…

This Phase III trial tests whether a modified short-course radiation that spares nearby lymph nodes, combined with chemotherapy (CAPOX) and the immunotherapy drug tislelizumab, works better than standard radiation plus chemotherapy for people with a certain type of rectal cancer …

This pilot study tests a new rectal applicator for delivering radiation therapy to elderly patients with inoperable rectal cancer. The treatment combines external beam radiation with three sessions of internal radiation (brachytherapy) using the new device. The study aims to see …

This early-stage study tests the safety of combining the chemotherapy drug TAS-102 with radiation therapy for people with stage II or III rectal cancer that hasn't been treated yet. The goal is to find the safest dose of TAS-102 to use with radiation before surgery to remove the …

This study tests a new surgical technique called transanal total mesorectal excision (taTME) for rectal cancer. Instead of operating from the abdomen, surgeons work from the anus upward, which may make it easier to remove the tumor completely. The trial includes 100 adults with e…

This phase 2 trial tests whether adding the experimental drug galunisertib to standard chemoradiation can improve outcomes for people with locally advanced rectal cancer. About 50 participants will receive the combination over 8 weeks, followed by surgery. Researchers will also s…

This study tests whether giving either short-course radiation or long-course chemoradiation, followed by a strong chemotherapy cocktail (mFOLFOXIRI), can shrink low rectal tumors enough to avoid radical surgery. About 66 adults with stage T2-4a rectal cancer whose tumor is within…

This phase 2 trial is testing a combination of two drugs, cabozantinib and nivolumab, in 48 people with advanced colorectal cancer that has not responded to standard treatments. The goal is to see if the combination can shrink or stabilize tumors. All participants have a type of …

This early-phase trial tests whether using MRI scans during radiation treatment can help doctors adjust the radiation dose to better target rectal cancer. Twenty people with stage II or III rectal cancer will receive standard chemotherapy plus MRI-guided radiation. The main goal …

This study planned to test two drugs—regorafenib (a pill) and lorigerlimab (given by IV)—in people whose rectal cancer had come back or grown after standard treatment. The goal was to see if the combination was safe and effective. However, the trial was withdrawn before enrolling…

This trial tests a modified stapling technique (MST) against the standard method in 450 adults having minimally invasive rectal cancer surgery. The goal is to see if MST reduces the chance of anastomotic leaks, a serious complication. Participants will be randomly assigned to one…

This phase II trial tests how well chemoradiation (using fluorouracil, leucovorin, and oxaliplatin) works before surgery for stage II or III rectal cancer. The study looks at different time intervals between chemoradiation and surgery to see which timing leads to the best tumor s…

This study tests whether giving a powerful mix of chemotherapy and radiation before surgery can completely eliminate rectal cancer in more patients. About 38 adults with rectal cancer will receive the experimental treatment and be followed for up to 4 years. The goal is to see if…

This phase 2 trial tests a two-step approach for high-risk rectal cancer: first, a strong chemotherapy cocktail (FOLFOXIRI), followed by radiation combined with a chemo pill (capecitabine). The goal is to shrink tumors before surgery, making them easier to remove. The study invol…

This phase 2 trial tests whether adding a stronger chemotherapy regimen (FOLFOXIRI) before the usual chemoradiation and surgery can improve outcomes for people with high-risk locally advanced rectal cancer. About 72 participants will be randomly assigned to either standard treatm…

This study tests whether a special type of internal radiation (contact X-ray brachytherapy) given after standard chemoradiation can help more people with early rectal cancer keep their rectum, compared to standard external beam radiation. About 148 adults with small, early-stage …

This study investigates genetic factors that may increase the risk of developing colorectal cancer at a young age (18-50). Researchers will collect blood or saliva samples and review medical records from 818 participants, including patients and their family members. The goal is t…

This study involves 320 adults with advanced rectal cancer who received standard chemoradiotherapy and surgery. Researchers are building a computer model that uses MRI scans and patient data to predict whether the cancer has completely disappeared after treatment. The goal is to …
