N2 - Appendectomy is standard of care for uncomplicated appendicitis, but cancer patients may not be optimal surgical candidates. Interval appendectomy is controversial, and appendiceal malignancy is rare. Study objectives were to review the role of surgery, observation, and interventional radiology (IR)-guided drainage in patients with appendicitis and advanced malignancy. Retrospective review was performed on cancer patients presenting to a tertiary academic cancer center from January 1, 2001 to December 31, 2014. Patients diagnosed with appendicitis were assigned to observation, surgery, and IR drainage after surgical evaluation. Success rates of initial treatment strategies were calculated. Rates of interval appendectomies and pathology were reviewed. Of 72 consults, 32 patients were included. Median age was 53 years, 50 per cent (16/32) were male, 50 per cent (16/32) had chemotherapy less than six weeks to presentation, and 63 per cent (20/32) had advanced stage malignancy. Of the 62.5 per cent (20/32) observed, 25 per cent (8/32) received immediate surgery, 12.5 per cent (4/32) required IR drainage, and 69 per cent (22/32) of patients were initially managed without surgery. Interval appendectomy rate was 19 per cent (6/32). Pathology confirmed appendiceal malignancies in 9.3 per cent (3/32). Cancer patients with acute appendicitis are frequently observed. High incidence of appendiceal malignancy may be due to the older median age. Interval appendectomy should be considered in this population.
