ABSTRACT

Background: Appendiceal tumors are found in about 1% of appendectomies performed and 0.5% of intestinal neoplasias. Appendiceal carcinoids are the predominant histology in this group and are usually casual after appendectomy for other reasons. The prognosis is excellent and survival is 95% at 5 years after surgery.
Methods: Retrospective analysis of all patients with appendiceal carcinoid surgery in our hospital for 20 years (1990-2010) and survival at 5 years. We also discuss the need for additional treatment and testing for follow-up visits.
Results: 42 patients underwent surgery for appendiceal carcinoid tumor. 38 of them were operated on urgently, mostly for suspected acute appendicitis, without having reached the carcinoid tumor diagnosed preoperatively in any of them. The predominant symptomatology at admission was abdominal pain. Surgical treatment was appendectomy in 34 patients (12 laparoscopic), 7 patients required colon resections over intraoperatively by colonic involvement; only one patient required reoperation to complete right hemicolectomy. 2 patients had disseminated disease at diagnosis (liver metastases). The 5-year survival is over 95%, with no recurrence.
Conclusions: The appendiceal carcinoid tumor is difficult to diagnose preoperatively. Appendectomy surgical treatment is usually sufficient, although colonic resections may be needed for dissemination. The 5-year survival is over 95%.
