[Carcinoid of the appendix. Clinical report of 3 cases and diagnostic and therapeutic considerations]

The Authors report three cases of carcinoid of the appendix and discuss the difficult preoperative diagnosis and the different therapeutic options available. Over the period from January 1994 to December 1999, in the Surgery Unit of Penne Hospital, 424 appendicectomies were performed in 182 males and 242 females (age: 12-86 years; mean age: 39.9 years). In three cases the histological response was positive for carcinoid of the appendix. No postoperative mortality or morbility were reported. The authors analyze the biological peculiarities and the prognostic factors associated with appendiceal carcinoid tumours, such as tumour size and the lymphatic or vascular infiltration of the mesoappendix (and the corresponding more aggressive surgical treatments) and recommend an appropriate postoperative follow-up since synchronous or metachronous bowel carcinomas are likely to occur. Pharmacological therapy has also made important progress, with the possibility of administering compounds capable of interfering with tumour development and neoplastic growth.
