Development and Clinical Application of a Novel Imaging Grading System for Pheochromocytoma and Paraganglioma (PPGL)

China500 participantsStarted 2017-01-01

Plain-language summary

This study aims to develop and preliminarily validate an anatomy-morphological risk grading system (IUPU-PPGL Grading) based on preoperative imaging 3D reconstruction, in order to quantitatively assess surgical complexity and perioperative safety in PPGL patients, and to evaluate the value of this grading system for formulating individualized surgical strategies.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * ① Patients who underwent curative surgical resection (including laparoscopic, robot-assisted, or open surgery) at our hospital within the study period; * Postoperative pathological confirmation of PPGL; * Availability of complete preoperative imaging data; ④ Availability of complete perioperative clinical data, including anesthesia records, surgical records, and postoperative hospitalization information; ⑤ Age ≥ 18 years. Exclusion Criteria: * ① Lack of key imaging data or poor image quality that could not meet evaluation requirements; * Requirement for concurrent complex surgery for other diseases, making it difficult to independently assess perioperative indicators; ③ History of biopsy only, exploratory surgery, or presence of recurrence, bilateral, or multifocal lesions, preventing independent evaluation; ④ Primary tumors located in special sites (e.g., pelvic, bladder, spermatic cord, or other rare extra-adrenal locations), leading to incomparable surgical approaches and perioperative outcomes.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
