Filter by:This clinical study aims to assess feasibility, safety, tolerability, and compliance of a Nonessential Amino Acid Restriction (NEAAR) medical food in adult patients with locally advanced rectal cancer during standard of care short course radiotherapy followed by standard of care chemotherapy.
Brief Summary Background The preservation of the left colic artery (LCA) during rectal cancer resection remains a topic of controversy, and there is a notable absence of robust evidence regarding the outcomes associated with LCA preservation. And the advantages of robotic-assisted laparoscopy (RAL) surgery in rectal resection remain uncertain. The objective of this study was to assess the influence of LCA preservation surgery and RAL surgery on intraoperative and postoperative complications of rectal cancer resection. Methods Participants who underwent laparoscopic (LSC) or RAL with or without LCA preservation resection for rectal cancer between April 2020 and May 2023 were retrospectively assessed. The patients were categorized into two groups: low ligation (LL) which with preservation of LCA and high ligation (HL) which without preservation of LCA. A one-to-one propensity score-matched analysis was performed to decrease confounding. The primary outcome was operative findings, operative morbidity, and postoperative genitourinary function.
The purpose of this process is to clarify the characteristics of gut microbiota changes in patients with locally advanced rectal cancer undergoing preoperative neoadjuvant treatment, and to identify key bacterial species closely related to sensitivity to radiotherapy. This aims to elucidate the mechanism linking gut microbiome dysbiosis with radiotherapy sensitivity, thereby providing new combined treatment strategies to enhance the efficacy of radiotherapy.
The goal of this clinical trial is to learn if PD-1 monoclonal antibody combined with radical chemoradiotherapy works to treat rectal squamous cell carcinoma (rSCC). lt will also learn about the safety of the regime. The main questions it aims to answer are: Does PD-1 monoclonal antibody combined with radical chemoradiotherapy improve survival prognosis? What is the complete response rate (CCR) of the regime？ Researchers will compare PD-1 monoclonal antibody combined with radical chemoradiotherapy to previous study to see if this regime works to treat rSCCs. Participants will receive chemotherapy with DDP and 5-FU, immunotherapy with PD-1 monoclonal antibody and radiotherapy with a total dose of 50-54GY.
The goal of this clinical trial is to learn if using topical tretinoin will help patients with colorectal cancer who are experiencing an acneiform rash as a side effect of their treatment. Researchers will compare the use of tretinoin on one side of the face to the use of a placebo on the other side of the face to see if there is an impact.
In the era of laparoscopy, ileostomy via specimen extraction site has been proposed as a novel approach for temporary ostomy creation to prevent anastomotic leak after laparoscopic low anterior rectal resection. Whether suturing the layer of the peritoneum and anterior rectus sheath affects the safety of this novel approach has not been investigated.
The purpose of the study is to evaluate the feasibility and acceptability of a dietary intervention (FEED-FF) that includes fermented foods (FF), among locally advanced rectal cancer patients, and to explore whether this diet can improve outcomes in rectal cancer patients receiving chemoradiotherapy (CRT).
To explore the complete response (CR) rate of improved short-course radiotherapy combined with CAPOX and tislelizumab for locally Advanced Mid-low Rectal Cancer
The goal of this one-arm clinical trial is to implement and study the oncological outcomes of nonoperative management of rectal cancer having complete clinical response to neoadjuvant therapy. The main questions to answer are - if the oncological results of nonoperative management after Nordic practice in chemoradiotherapy indications differ from experiences elsewhere - what is the organ preservation rate - what is the local regrowth rate
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.
