Objective: The aim of this study was to determine whether appendectomy should be a routine part of the surgical staging procedures for patients presenting with epithelial ovarian cancer apparently confined to the pelvis.
Methods: We reviewed the medical records of 337 patients who underwent appendectomy at the time of initial surgery for epithelial ovarian cancer at Seoul National University Hospital between January 1991 and August 2006. Excluded were those who met any of the following exclusion criteria: overt gross intra?abdominal metastasis or FIGO stage IV disease (n=161), double primary cancer (n=12), or incomplete clinicopathologic data (n=15).
Results: Of 149 patients included in this analysis, 32 had ovarian tumors of low malignant potential (21%) and 117 had invasive epithelial ovarian cancer (79%). Histologic types were as follows: 34 serous (22.8%), 61 mucinous (40.9%), 28 endometrioid (18.8%), 16 clear cell (10.7%), and 10 other tumors (6.7%). One hundred twenty?two patients were stage I (82%), 21 stage II (14%), and 6 stage IIIa (4%). Of 6 patients with stage IIIa, 3 had microscopic metastasis in omentum, 2 in small bowel serosa, and 1 in abdominal peritoneum. None of these patients with disease grossly confined to the pelvis had appendiceal metastasis and, therefore, none of the patients had their diseases upstaged due to isolated appendiceal involvement.
Conclusion: Appendectomy is probably an unnecessary surgical procedure for patients presenting with epithelial ovarian cancer apparently confined to the pelvis. Histologic type and tumor grade did not appear to influence the appendiceal metastasis in these patients.
