Acute PresentatiOn of CoLorectaL Cancer: an internatiOnal snapshot



What is the APOLLO Study?

APOLLO is an international, multi-centre, prospective observational cohort study of acutely presenting colorectal cancer exploring the operative and non-operative management of emergency presentations of colon and rectal cancer globally. The study is being delivered by the European Students Research Collaborative (EuroSurg), and will be facilitated in Australia by TASMAN and Aotearoa New Zealand by STRATA and TASMAN

What Are APOLLO’s Main Objectives?

APOLLO is an international, prospective multi-centre cohort study that aims: 

  1. Describe the variation in the operative and non-operative management of emergency presentations of colon and rectal cancer in an international cohort.

  2. Identify risk factors for mortality (intraoperatively, at 30-days and at 90-days) and ostomy rates (at 30- and 90-days) in patients deemed for active management (i.e., not for palliative management) to develop a risk prediction model

  3. Validate risk criteria of large bowel obstruction in patients with previously known colorectal cancer undergoing neoadjuvant chemotherapy or awaiting elective surgery.

Through facilitating the APOLLO Study in Aotearoa New Zealand, we aim to build collaborative research capacity within medical students and junior doctors.
