Filter by:This was a propensity-score matched observational analysis, comparing the oncological outcome of surgical resection vs watch and wait apporach for rectal cancer patients with a cCR.
This is a open-label, single-arm study to investigate the safety and efficacy of total neoadjuvant treatment (TNT) in patients with locally advanced resectable rectal cancer.
After undergoing restorative proctectomy for rectal cancer, many patients are left with significant bowel dysfunction, known as Low Anterior Resection Syndrome (LARS). Increased LARS severity correlates with worse perceived global health status and quality of life (QoL). Among patients undergoing rectal resection with a permanent ostomy, there is evidence that supportive and educational interventions improve QoL, ostomy proficiency, self-efficacy and knowledge. However, evidence regarding the impact of such interventions in patients who undergo restorative proctectomy is lacking, despite the latter operation being far more frequently performed. The overall goal of this study is to evaluate the extent to which a LARS Patient-Centered Program impacts on patient-reported outcome measures (PROMs) after restorative proctectomy for rectal cancer. This is a randomized-controlled muticenter trial that will include patients who have undergone restorative proctectomy for neoplastic disease (benign or malignant) located in the rectum (0-15cm from the anal verge) with a diverting ostomy and who are scheduled for ostomy closure.
The investigators will perform CT three-dimension reconstruction for middle-low rectal cancer patients who have enlarged lateral lymph nodes to recognize the variance of pelvic vessels, by which to help reduce operative time and blood loss, localize the lateral lymph nodes, improve the lymph node harvested and positive rate. Besides, The investigators will label the vessels near the interested node to achieve node-by-node for further investigation.
This phase II, randomized pilot trial studies the effect of the consumption of foods made with resistant starch compared to foods made with corn starch on biomarkers that may be related to colorectal cancer progression in stage I-III colorectal cancer survivors. Foods made with resistant starch may beneficially influence markers of inflammation, insulin resistance, and the composition of gut bacteria in colorectal cancer survivors.
The objective was to evaluate the use and outcomes of robotic proctectomy compared to open and laparoscopic approaches for rectal cancer in the elderly. A retrospective cross-sectional cohort study utilizing the Nationwide Inpatient Sample (NIS; 2006-2013) was performed.
Hernia formation at sites of ostomy closure is a common complication. The investigator believes that using evidence based hernia repair techniques as a preventive measure during closure of ostomies will reduce the incidence of hernia formation. In this trial, the investigator will pilot a novel technique of large pore monofilament polypropylene mesh reinforcement of the abdominal wall defects that remain after closure of an ileostomy to evaluate for safety and begin to evaluate the effectiveness compared to standard techniques.
Background: A new cancer therapy takes white blood cells from a person, grows them in a lab, genetically changes them, then gives them back to the person. Researchers think this may help attack tumors in people with certain cancers. It is called gene transfer using anti-KRAS G12D mTCR cells. Objective: To see if anti-KRAS G12D mTCR cells are safe and cause tumors to shrink. Eligibility: Adults ages 18-72 who have cancer with a molecule on the tumors that can be recognized by the study cells Design: Participants will be screened with medical history, physical exam, scans, photography, and heart, lung, and lab tests. An intravenous (IV) catheter will be placed in a large vein in the chest. Participants will have leukapheresis. Blood will be removed through a needle in an arm. A machine will divide the blood and collect white blood cells. The rest of the blood will be returned to the participant through a needle in the other arm. A few weeks later, participants will have a hospital stay. They will: - Get 2 chemotherapy medicines by IV over 5 days. - Get the changed cells through the catheter. Get up to 9 doses of a medicine to help the cells. They may get a shot to stimulate blood cells. - Recover in the hospital for up to 3 weeks. They will provide blood samples. Participants will take an antibiotic for at least 6 months. Participants will have several follow-up visits over 2 years. They will repeat most of the screening tests and may have leukapheresis. Participants blood will be collected for several years.
How to reduce the complications of perineal wound after abdominoperineal resection (APR) has always been a hot topic in the medical field.To reduce the complications of perineal wound and the primary healing of perineal wound must meet the two principles of "unobstructed drainage" and " reduced tension closure".This concept is similar to the concepts of closure of enterostomy in rectal cancer patients. It was reported that use of cross-stitch closure can significantly reduce complications of closure of enterostomy. So the investigator ever used the "cross" closure to reconstruct the perineal wound of APR, which was really decrease the complications of perineal wound. However, more clinical trails was needed to confirm the conclusion.
Observational study to evaluate longitudinal quality of life according to standardized EORTC questionaires as well as functional Outcome, oncological outcome and toxicity in patients treated with neoadjuvant short term radiation or long-term chemoradiation followed by surgery
