GlobalSurg 3: Quality and Outcomes in Global Cancer Surgery

Inclusion criteria

• All consecutive patients undergoing therapeutic surgery (curative or palliative) for breast, gastric, and colorectal cancer should be included.
• Surgery is defined as a procedure requiring a skin incision performed under general or neuraxial (e.g. regional, epidural or spinal) anaesthesia.
• Both elective and emergency procedures should be included. Include patients in whom the pre-operative diagnosis was thought to be benign, but was subsequently found to be cancer, e.g. bowel obstruction found to be due to cancer during surgery.
• Include patients in whom the pre-operative diagnosis was thought to be cancer, but was subsequently found to be benign disease (ensure the "pathology" variable indicates not cancer; will not be included in primary analysis).
• Laparoscopic, laparoscopic-converted, robotic, and open cases should be included.
• Patients aged 18 years and over should be included .
• Surgery may be with curative or palliative intent. Include patients in whom curative surgery was attempted but abandoned, e.g. open/close laparotomy.

Exclusion criteria

• Operations where breast, gastric, or colorectal cancer is not suspected to be the primary pathology should be excluded.
• Patients undergoing a procedure purely for diagnosis or staging should be excluded, e.g. open breast biopsy, staging laparoscopy.
• Patients undergoing a procedure which does not require a skin incision should be excluded, e.g. colonoscopy/endoscopy alone, chemo/radiotherapy alone.
• Patients presenting with recurrence of breast, colorectal or gastric cancer should be excluded.
