Active clinical trials for "Rectal Neoplasms"

The goal of this observational study is to learn about the T1 relaxation time and T1 relaxation time properties of the disease in people with locally advanced rectal cancer. The main question it aims to answer is: Does MRI T1 relaxation time have a high diagnostic performance in recognizing fibrosis as a complete response to neoadjuvant treatment of rectal cancer? Participants will receive standard neoadjuvant treatment and be part of the standard examination programme regarding rectal cancer.

This study aimed at comparing the Comprehensive Complication Index (CCI), readmission rates, postoperative hospitalization days, duration of bearing the stoma (months), hospitalization costs, the number of hospitalizations with ghost ileostomy versus conventional loop ileostomy after low anterior resection for rectal cancer.

The objective of this study is to compare the postoperative analgesic effect of bupivacaine injection via ultrasound-guided erector spinae block versus transmuscular quadratus lumborum block in patients undergoing abdominal cancer surgery

Investigators use clinical trial to explore the role of sarcopenia and multimodal rehabilitation in prognosis of rectal cancer patients receiving concurrent chemoradiotherapy.

The aim of this study is to evaluate the efficacy of a brief psychoeducational intervention to improve the self-efficacy of patients with locally advanced rectal cancer who are initiating multimodality treatment (e.g., total neoadjuvant therapy).

To analyze the occurrence of defecation complications, rectal function, and quality of life indicators after sphincter-preserving surgery for middle and low rectal cancer, the stoma exudate was collected before the stoma was restored, and the defecation complications, rectal function and quality of life indicators were evaluated. The effect of anal reinfusion of stoma discharge on the recovery of intestinal function in patients.

Control of the effect of prehabilitation on postoperative morbidity, assessed by the Comprehensive Complication Index (CCI), in patients diagnosed with rectal cancer that will receive neoadjuvant Quimiorradiotherapy (NCRT) and subsequent surgery, performed at the beginning of NCRT or before surgery.

Patients with locally advanced non-metastatic adenocarcinoma of the rectum undergoing chemoradiation therapy will be assigned to 2 groups: the intervention group will be prescribed an individualized ketogenic eating plan to be followed throughout the treatment period the control group will be prescribed a diet therapy plan treatment following the international guidelines of clinical nutrition, also to be followed during treatment

This phase Ib/II study is a prospective, open-label, single arm, nonrandomized study of PEP503(radio-enhancer). There are 2 portions in this study. Escalation phase (Part Ib): A 3 + 3 dose escalation study design will be adopted in this phase to identify the recommended injection volume of PEP503 for intratumor injection. Expansion phase (Part II): Following the confirmation of the recommended volume of intratumor injection, 18 additional patients will be enrolled at the recommended volume level to evaluate for efficacy.

Lateral lymph nodes (LLD) metastasis is a major cause of local recurrence for advanced rectal cancer. As for the treatment strategies on LLN metastasis, there are huge controversies on whether lateral pelvic lymph nodes dissection (LLND) after neoadjuvant chemo-radiotherapy (nCRT) between Western and Eastern countries. Retrospective cohort evidences indicate that LLND following total mesorectal excision (TME) will bring benefit from cT3-4 rectal cancer, not regular predictive LLND, which will bring more side effects on the contrary. Existing reports tend to recommend LLND for specific individual with suspicious LLN metastasis. Moreover, there is a blank strict prospective randomized control study on the comparison of LLND+TME and LLND after nCRT. Therefore, our trial will compare the efficacy and safety of the two strategies for mid/low rectal cancer with suspicious LLN metastasis. The risk factors (such as radiologic factors, pathologic factors, and serum protein) to predict local recurrence and overall survival will be further investigated.
