Filter by:Preoperative 5FU based chemoradiotherapy is still the standard of treatment for locally advanced rectal cancer. About 15-20% of patients would achieve pathologic complete response (pCR) after neoadjuvant CRT, and the survival outcome was much better than that of non-pCR. Total neoadjuvant treatment had been evaluated a lot in recent years, including induction chemotherapy or consolidation chemotherapy, or concurrent chemoradiotherapy. We aimed to evaluated the safety and efficacy of total neoadjuvant treatemnt in locally advanced rectal cancer.
This study looks at the level of circulating tumor elements (cancer cells or DNA pieces floating in the blood) and how it may be related to how the tumor responds to standard treatment in patients with rectal cancer that has spread to nearby tissue or lymph nodes (locally advanced). Researchers will also compare the level and genetic characteristics of circulating tumor elements between individuals with rectal cancer and healthy individuals to understand how they may change over time. Information from this study may help researchers better understand rectal cancer.
The purpose of this study is to develop a technique that allows physicians to identify the first lymph nodes draining from a rectal tumor (the sentinel lymph nodes). Currently, there is no technique used to find these lymph nodes in the rectum during surgery and therefore many patients with rectal cancer need to undergo a total rectal resection. Dyes, tracers, imaging and a gamma probe will be used in this study during a standard minimally invasive transanal endoscopic surgery (TES) to try to locate these lymph nodes. If surgeons are able to locate these lymph nodes they will be removed during surgery. If the technique is successfully developed as a result of this research, it could help patients in the future with early stage rectal cancer by allowing doctors to see if their cancer has spread to the lymph nodes of the rectum without having to undergo a total rectal resection. These patients would then be able to undergo a TES combined with a lymph node dissection to gain more knowledge about the stage of their disease. This knowledge would then be used to determine if and what further treatment is necessary for the patient's rectal cancer.
This study is designed to test the efficacy and safety of total neoadjuvant induction and consolidation CapeOX plus neoadjuvant intensity modulated radiotherapy with concurrent capecitabine for MRI defined high-risk rectal cancer.
This study is designed to test the efficacy of tailored operative or non-operative management (NOM) for MRI defined low-risk rectal cancer following neoadjuvant intensity modulated radiotherapy with concurrent capecitabine plus consolidation CapeOX. The main purpose of this study is to increase organ-preservation rate for low-risk rectal cancer patients.
This trial is to assess the efficacy and feasibility of consolidation chemotherapy after neoadjuvant chemoradiotherapy for locally advanced mid or low rectal cancer.
The purpose of this study is to determine: (1) whether laparoscopy-assisted nerve-preserved total mesorectal excision (LNTME) is as safe as open TME for rectal cancer, and (2) whether LNTME is more effective for protection of pelvic autonomic nerve function from surgical impairing when comparing to open TME.
The purpose of this study is to evaluate the safety and oncological feasibility of robot-assisted surgery for mid/low rectal carcinoma compared with laparoscopic surgery.
The DREAM study will assess the diagnostic accuracy of diffusion-weighted MRI in combination with other imaging modalities (multiparametric MRI and CT Scan) in determining the true status of disappearing liver metastasis (DLM) detected after conversion systemic therapy for unresectable or borderline resectable colorectal liver metastasis (CRLM).
The aim of this study is to investigate if day-case closure of ileostomy is feasible and safe.
