Study Design and Data Source
A single institution, retrospective study of patients undergoing colorectal cancer surgery at The Prince Charles Hospital.
Patients were divided in two age groups in order to assess the short-term outcomes of patients over 85. The comparison group was chosen to be those between 75-84 years of age. The demographic features, comorbidities, surgical characteristics, short-term outcomes and complications were compared between the two groups.
For the second aim of the study, patients over the age of 85 who underwent laparoscopic colorectal surgery were compared to those who underwent open surgery.
Patient charts were individually reviewed and data extracted by trained medical personnel. Data was obtained from previous admissions, current admissions as well as correspondence letters, follow up documentation and outpatient/readmission notes.
Inclusion criteria included those who underwent surgical resection of biopsy proven colorectal cancer at The Prince Charles Hospital between January 2010 and December 2018. Patients were excluded if they had endoscopic resection of the malignant lesion without surgical intervention.
