The Anatomical Localization of the Inferior Mesenteric Artery in Relation to the Left Colonic Artery
To observe and measure the distance between the origin of LCA (left colonic artery，LCA) and IMA (inferior mesenteric artery，IMA) root and the distance between IMA and IMV (inferior mesenteric vein，IMV) at the origin of LCA in rectal cancer patients. Statistical analysis of intraoperative measured data, on the basis of the …
Reasons for Non-reversal of Temporary Stomas After Surgeries of Mid-low Rectal Cancer （NORESTO Study）
The goal of this observational study is to learn about in mid-low rectal patients who received temporary ostomies after surgery of the primary tumors. The main questions it aims to answer are: To explore the proportion of temporary stomas that cannot be reversed after radical surgery for mid-low rectal cancer …
Changes of Low Anterior Resection Syndrome and Balance Ability in Patients With Rectal Cancer.
The purposes of this study are to explore the trajectory of symptom distress and balance ability in patients with rectal cancer.
Oncological Differences Between Transanal and Laparoscopic Total Mesorectal Excision for Rectal Cancer.
The primary purpose of this study is to compare the differences of oncological in rectal cancer patients undergoing laparoscopic or transanal endoscopy radical resection. The secondary purpose is to compare the effect of two different surgical methods on prognosis.
Lumeneye Rectoscope for Assessment on Tumor Response After Total Neoadjuvant Treatment in Rectal Cancer
The objective of this prospective international cohort is to evaluate the LUMENEYE rectoscope for assessment on tumor response after total neoadjuvant treatment in rectal cancer. Patients included in this study will be patients who initially will be good candidates for organ preservation. The participating centers are all expert centers in …
MRI Guided SIB Radiotherapy in Neoadjuvant Therapy for Advanced Rectal Cancer
Colorectal cancer has an annual incidence surpassing 700,000 cases globally, ranking as the fourth most prevalent cancer with the second-highest mortality rate. Rectal cancer accounts for approximately one-third of newly diagnosed colorectal cancer cases. Stages II (cT3-4/N0) and III (cT1-4/N1-3) rectal cancer are commonly classified as Locally Advanced Rectal Cancer …
Longterm Functional Outcomes in Patients Undergoing Organ Preserving Treatment for Rectal Cancer With or Without Local Excision After Chemoradiotherapy
Treatment of rectal cancer by standard neoadjuvant chemoradiotherapy protocols leads to a complete response in about 15% of patients, or even a higher fraction if radiotherapy is followed by an Oxaliplatin based chemotherapy as published recently. If patient presents with a (near) complete response at the time of restaging after …
Flexible Colonoscope Assisted Hybrid Transanal Total Mesorectal Resection (taTME)
The investigators propose to use flexible endoscopy combined with transanal total mesorectal resection to further reduce anal injury.
Hypofractionated Palliative Radiotherapy in Patients With Advanced Non-operable Rectal Cancer
Many patients with rectal cancer were not candidates for surgical resection because advanced age, comorbidities, or multiple synchronous metastases. In this scenario only comfort measures or different palliative radiotherapy regimens are applied, from single doses to treatments lasting several weeks. The aim of this prospective study is to describe the …
PET/MR Evaluation of Regression Grading After Neoadjuvant Therapy for Rectal Cancer
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 …
