Filter by:The objective of this observational study was to investigate the clinical significance of benign mesenteric lymph node （BLNE） enlargement in patients with colorectal cancer. The main questions it aims to answer are: Do patients with benign mesenteric lymph node enlargement have a better prognosis? What are the clinical characteristics of benign mesenteric lymph node enlargement? As part of routine medical care for colorectal cancer, we will follow up with all participants over the course of the study.
Background: People with colorectal cancer (CRC) or gastroesophageal cancer (GEC) must often have major surgery to remove tumors from the esophagus, stomach, colon, or rectum. These surgeries can have adverse effects on their quality of life. Researchers want to know if one or two approved drugs (nivolumab with or without ipilimumab) can help people with CRC or GEC delay or avoid surgery. Objective: To test 1 or 2 drugs in people with CRC or GEC. Eligibility: People aged 18 years and older with CRC or GEC. People with GEC must also have changes in a particular gene. Design: Participants will visit the clinic about 15 times over the first 2 years. Each visit will last 4 to 8 hours. Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans. Small samples of tissue will be collected from their upper or lower digestive tract where the tumor is located. Both ipilimumab and nivolumab are administered through a tube attached to a needle inserted into a vein in the arm. Some participants will receive both drugs. Some will receive only nivolumab. Treatment will be given once every 3 weeks for up to 8 cycles up to (24 weeks). Participants will be evaluated every 6 weeks. Those who are responding well will continue with the drug treatments. If their disease progresses, they will go to surgery. After treatment ends, participants will have follow-up visits every 6 months for up to 5 years....
Intraoperative pelvic autonomic nerve (PAN) injury is the dominant reason for genitourinary malfunction after total mesorectal excision (TME), particularly in low rectal tumours. TME necessitates meticulous, sharp dissection with an awareness of the PAN pathway. In particular, laparoscopic TME (L-TME) is technically difficult and requires advanced laparoscopic surgical skills. Comparing with the conventional laparoscopic approach, 3D vision, surgeon-manipulated camera systems, and multi-degree-of-freedom robotic instruments facilitate identification and preservation of the PAN during robotic-assisted TME (R-TME), theoretically facilitating favourable recovery of postoperative genitourinary function. Previous studies have mostly focused on the impact of advanced robotic technologies on postoperative functions. However, in addition to robotic surgical technology, postoperative function is impacted by multiple other intricate factors, such as oncology, comorbidities, postoperative complications, and adjuvant chemoradiotherapy. Consequently, the superiority of robotic surgery in terms of recovery of postoperative genitourinary function has been controversial in previous studies. Hence, to comprehensively evaluate the effect of robotic technology on postoperative genitourinary function, we conducted a prospective controlled study comparing the conventional approach and robotic surgery.
Previous studies have indicated a high incidence of sleep disturbances and anxiety symptoms in individuals with colorectal cancers prior to undergoing surgery, leading to worsened postoperative pain, slower recovery, and higher risk of chronic pain. The enhancement of sleep quality is intricately linked to reducing stress. Preoperative drugs that combine hypnosis and anti-anxiety have not been studied in colorectal cancer patients. Midazolam oral solution is safe and effective for short-term hypnotic and anti-anxiety effects in clinical preoperative settings. In the current randomized controlled clinical trial, 280 patients experiencing sleep disturbance or anxiety prior to colorectal cancer surgery will receive midazolam solution to assess its potential efficacy in reducing postoperative pain, expediting recovery, and decreasing the likelihood of chronic pain. Additionally, the study aims to explore the potential connections between midazolam administration and reductions in stress and inflammation.
This study is a further observation and follow-up of the patients enrolled in the registration number NCT05920980 to further evaluate the effect of long-term infusion of lidocaine on postoperative chronic pain, long-term quality of life and survival rate in patients undergoing colorectal cancer surgery.
Neoadjuvant chemotherapy has gained acceptance in treating locally advanced breast cancer, esophageal cancer, gastric cancer, and rectal cancer. However, the role of neoadjuvant chemotherapy for locally advanced colon cancer is still in the exploratory stage. The objective of this study is to explore the efficacy and safety of nanoliposomal irinotecan and oxaliplatin combined with capecitabine as a novel conversion therapy for locally advanced colorectal cancer patients.
Evaluating the value of dynamic monitoring of a colorectal cancer liver metastasis cohort underwent curative resection after receiving multipoint ctDNA detecting in predicting recurrence prognosis and guiding adjuvant chemotherapy treatment.
Currently, the approved third-line treatments for metastatic colorectal cancer (mCRC) include regorafenib, fruquintinib, and trifluridine/tipiracil(TAS-102). In recent years, several phase I/II studies evaluated the combination of TAS-102 and bevacizumab in mCRC patients who were refractory to standard therapies and showed promising antitumor efficacy and manageable toxicity. In this single-center phase II study, the investigators explored the efficacy and safety of irinotecan, TAS-102, plus bevacizumab in a third-line or beyond therapy for patients with mCRC.
Major abdominal surgeries are traditionally performed via laparotomy. Analgesia is routinely administered during the postoperative period. The goal is to investigate the effects of laparotomy and analgesia methods on diaphragm function.
The purpose of this clinical investigation is to evaluate the safety and feasibility of the ColoSeal ICD System in a prospective, multicenter, single-arm study. The ColoSeal ICD System is intended to be used to protect a damaged segment of colon such as a surgical anastomosis, anastomosis leak, or perforation from contact with fecal flow for up to 21 days. The device will be evaluated in adult patients with rectal and rectosigmoid cancer undergoing a resection with a colorectal anastomosis.
