Colorectal Resections in Patients With Retroperitoneal Sarcoma

Germany, Switzerland120 participantsStarted 2025-01-27

Plain-language summary

COLOSARC-Q is a multicenter study with the objective of providing an up-to-date assessment of colorectal resections and reconstruction techniques in the context of multivisceral resections for retroperitoneal sarcomas, as well as colorectal surgery-associated complications and their impact on patients' quality of life. In multivisceral resections involving the colon and rectum, the primary aim is to achieve complete resection and preserve organ function. However, multivisceral resections have a high risk of perioperative morbidity including anastomotic leakage. The proposed project aims to determine the number of primary anastomoses, their insufficiency rates, and the fraction of patients with primary and secondary stomas. In addition, the patients' quality of life after multivisceral sarcoma resection is to be recorded using standardized surveys. The analysis has the potential to facilitate intraoperative decision-making for colorectal resections in the context of multivisceral resections.

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.
