Filter by:This study aims to compare the postoperative outcomes of low rectal cancer patients who underwent surgery with Natural Orifice Specimen Extraction (NOSE) versus traditional Pfannenstiel extraction.
This project aims to evaluate the role of 18F-FAPI combined with 18F-FDG PET/MRI imaging in quantitatively and accurately evaluating the grading of rectal cancer after SCRT neoadjuvant therapy in patients with advanced rectal cancer as the research object, with postoperative histopathological analysis as the reference index, and to assess the ability of patients to achieve pCR. A diagnostic model and evaluation system will also be constructed.
The Transanal Transection and Single-Stapled anastomosis (TTSS) technique may be a valid alternative to traditional double-stapled anastomosis for low rectal cancer surgery. This study aims to compare the postoperative and functional outcomes of patients receiving TTSS and traditional double-stapled anastomosis.

This study is a multicenter, open, and phase I dose increasing clinical study. Based on the UGT1A1 * 28 and * 6 genotypes of patients with locally advanced rectal cancer, determine the dose limiting toxicity (DLT) and maximum tolerable dose (MTD) of weekly irinotecan liposomes in concurrent chemoradiotherapy with capecitabine, investigate the tolerance of irinotecan liposome combined with capecitabine in concurrent chemoradiotherapy with locally advanced rectal cancer, and recommend the dosage for Phase II clinical study，and explore the pharmacokinetic characteristics of irinotecan liposomes combined with capecitabine.At the same time，Preliminary observe the efficacy and safety of irinotecan liposomes combined with capecitabine in chemoradiotherapy.The study plans to recruit 30 patients with advanced rectal cancer who have not received any therapy.
The surgical management of rectal cancer includes a Total Mesorectal Exicison (TME). TME can be performed by open, laparoscopic, robotic or transanal approaches, as long as the oncological principles for the resection are achieved. Unfortunately, up to 90% of these patients will present a change in bowel habit, ranging from an increased frequency of bowel movements to the degree of fecal incontinence or evacuation dysfunction. Of these patients, 25-50% will have a severe alteration in the quality of life. This wide spectrum of symptoms has been called "low anterior resection syndrome" (LARS). Other collateral damage is the change in sexual and urinary function, due to hypogastric plexus injury. There is a significant lack of multicenter prospective studies that provide evidence, and that reveal the functional results and quality of life of these techniques available to date for the management of rectal cancer. The study is set up as a prospective multicentre observational study. Inclusion criteria are: 1) patients over 18 years old, 2) diagnosed with rectal cancer located below the peritoneal reflection, defined by pereoperative MRI, 3) undergoing Open, laparoscopic, robotic or Transanal Total Mesorectal Excision (taTME) approaches, 4) with/withou derivative stoma and 5) with/without neoadjuvant treatment. Exclusion criteria are: 1) Upper rectal cancer, located above the peritoneal reflection, 2) previous radical prostatectomy, 3) previous pelvic radiotherapy, 4) rectal resection without primary anastomosis, 5) intraoperative findings of peritoneal carcinomatosis, 6) stage IV disease, 7) multivisceral or en-bloc resection, which includes uterus, prostate, vagina or bladder, 8) rectal resection due to a benign condition, 9) rectal resection due to a recurrence of rectal cancer (previous anterior resection or another pimary neoplasm), 10) rectal resection following a 'watch & wait' program, 11) emergency surgery, 12) previous derivative colostomy 13) inflammatory bowel disease. Accepting an alpha risk of 0.05 and a beta risk of 0.2 in a two-sided test, 45 subjects are necessary in first group and 45 in the second to recognize as statistically significant a difference greater than or equal to 2 units. The common standard deviation is assumed to be 3. It has been anticipated a drop-out rate of 20% Primary outcomes are LARS and Vaizey score. Secondary outcomes included are QLQ C30 and CR29, sexual function questionnaire (female/male), urinary function questionnaire and postoperative complications (Clavien-Dindo classification) Data will be collected in an online secure and protected repository (Castor edc). The planned study period is 2 years (September 2021 - September 2023). It is essential to have a validated instrument that allows us to assess sphincter function and the different aspects of quality of life in operated patients, since increased survival in this pathology has led to greater importance in the evaluation functional outcome and quality of life; Furthermore, there are recent studies that speak of the direct relationship between these factors.
Colorectal cancer is the 2nd and 3rd most common cancer in respectively women and men, of which about 40% is located in the rectum. The gold standard treatment for rectal cancer (RC) is a low anterior resection, combined with chemoradiotherapy. However, this treatment will negatively impact different aspects of bowel function and the patients' quality of life. These bowel symptoms often remain prevalent, even at 12 months after RC treatment. Most assessment tools are however not capable of capturing the full range or therapeutic-related evolution of these bowel symptoms. Consequently, the aim is to develop a validated bowel diary for diagnosing and evaluation of all bowel symptoms.
The preservation surgery of the anal sphincter has become a standard procedure for the treatment of rectal cancer and is now possible even when the tumor is close to the anus, thanks to the advancement of surgical techniques. This procedure allows patients to avoid a permanent artificial anus and enables them to evacuate through the anus, maintaining the continuity of the intestine, making it a highly preferred surgical option. Additionally, advancements in tumor treatments have led to improved long-term survival rates. However, this anal sphincter preservation surgery inevitably can cause functional abnormalities in the rectum, and around 90% of patients experience changes in bowel habits after surgery. The characteristic symptoms occurring after rectal cancer surgery, such as diarrhea, urgency of bowel movements, frequent bowel movements, and fecal incontinence, are referred to as Anterior Resection Syndrome (ARS). Particularly, symptoms following low anterior resection surgery for lower rectal cancer are termed Low Anterior Resection Syndrome (LARS). These symptoms are most severe immediately after surgery, persisting up to 1-2 years, with some improvement over time. However, in many patients, LARS can remain a lifelong challenge, significantly impacting their quality of life. Currently, there is no definitive method to treat LARS, and symptom management is achieved through empirical treatment methods or medications. Many patients with LARS experience these symptoms predominantly at night, and it is presumed that their sleep quality is severely compromised, significantly affecting their overall quality of life. However, there is a lack of research on the prevalence of such patients and the appropriate treatments for them.
This research study is being conducted to improve the quality of care of participants who have a diagnosis of gastrointestinal cancer (anal, colon, rectal, esophageal, stomach, small bowel, appendix, pancreas, gall bladder, liver, neuroendocrine tumor of gastrointestinal origin). This study has 3 components as follows- 1. Ensuring appropriate biomarker testing and evidence-based care: Biomarkers are molecules in the tumor or blood that indicate normal or abnormal processes in participant's body and may indicate an underlying condition or disease. Various molecules, such as DNA (genes), proteins, or hormones, can serve as biomarkers since they all indicate something about participant's health. Biomarker testing can also help choose participant's treatment. Additionally, a tumor board will be conducted periodically to provide treatment recommendations to participant's treating physician. Participants will receive standard-of-care treatment if participant enroll in this study. Participant will not receive any experimental treatment. 2. Assistance with clinical trial enrollment. The study team will help participants enroll in a clinical trial appropriate for participant's condition. However, enrolling in a clinical trial is totally up to the participant. 3. Health literacy: The study team will provide information relevant to participant's diagnosis to enrich participant's understanding of participant's condition and treatment. Investigator will provide questionnaires to assess participant's understanding before and after participant's have been provided with educational/informational material appropriate for participant's diagnosis.
