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 This study
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
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 Results may not be published yet.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
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at standardizing the surgical process for patients with advanced or recurrent rectal cancer that has spread to nearby organs. The procedure, called pelvic exenteration, removes the tumor along with affected structures. The goal is to improve teamwork among surgeons and track patient outcomes and quality of life. Twenty-four adults will take part over three years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
standardized surgical and care process
What this could lead to
If successful, this could establish best practices for complex pelvic surgeries, potentially improving recovery and reducing complications for future patients.
What could go wrong
This is a small, early-stage study with only 24 participants, so results may not apply to all patients. It does not test new treatments, so direct benefits are uncertain.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients (age ≥ 20 years) with histologically confirmed locally advanced or recurrent rectal or anal adenocarcinoma invading adjacent pelvic structures (such as the sacrum, prostate, or bladder) who undergo pelvic exenteration (PE) with or without sacrectomy at Chang Gung Memorial Hospital during the three-year study period.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adult patients aged ≥20 years. * Histologically confirmed rectal adenocarcinoma or anal adenocarcinoma. * Tumor invasion of sacrum (requiring sacrectomy, S2-S4) or anterior structures (e.g., prostate), or lateral structures(SLAM, vessels, nerve) where resection of the invaded organ is necessary to achieve R0 resection, as determined by MDT. * Surgical candidacy confirmed by multidisciplinary review (colorectal surgery, urology, orthopedics, oncology, radiology, pathology). * Preoperative imaging (MRI, PET/CT) confirming resectable disease without distant metastasis. * Signed informed consent obtained. Exclusion Criteria: * Unresectable disease or widespread distant metastasis. * Severe comorbidities rendering major surgery or anesthesia unsafe. * Patients unable to complete postoperative follow-up or unwilling to participate in PROMs assessment.
