What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published

Summary

This study looked at 690 rectal cancer patients to see if the size of a specific artery (the middle rectal artery) on MRI scans could help predict whether cancer has spread to nearby lymph nodes. The goal was to create a tool that helps doctors decide if more extensive surgery is needed. The study found that certain imaging features, including artery diameter, were linked to lymph node spread, which could improve surgical planning.

Who is studied

This retrospective cohort study included adult patients (aged 18-75 years) with pathologically confirmed rectal adenocarcinoma located below the peritoneal reflection, who had complete preoperative pelvic MRI data and were treated at The First Affiliated Hospital of Fujian Medical University between 2022 and 2024. The study aimed to analyze this population to identify risk factors and develop a predictive model for clinically suspected lateral lymph node metastasis.

Inclusion Criteria: * Age at diagnosis between 18 and 75 years * Pathological confirmation of rectal adenocarcinoma by endoscopic biopsy * Imaging confirmation that the tumor was located below the peritoneal reflection * Availability of rectal MRI scans providing detailed imaging of the pelvic region * Received treatment at The First Affiliated Hospital of Fujian Medical University between January 2022 and December 2024 Exclusion Criteria: * Pathological diagnosis of non-primary rectal malignancies * Previous treatment for rectal cancer with chemotherapy, radiotherapy, or surgery, with the current presentation indicating recurrence * Incomplete rectal MRI data or poor image quality affecting interpretation * Incomplete medical or clinical records. Ultimately, 690 patients were included in the final analysis
