Objective: The ovarian mucinous tumors account for 10–15 % of ovarian tumors. These tumors are primary with ovarian origin or they may be metastatic which have their origins in other parts of the body, particularly in gastrointestinal tract. According to traditional literature, during surgery for ovarian mucinous tumors routine appendectomy was advocated due to differentiation of primary appendix carsinoma from ovarian tumors, but recent studies have demonstrated that appendectomy was performed only in cases with abnormal macroscopic appearance of appendix and in advanced stages of ovarian cancer. The aim of the present study is to investigate the correlation between macroscopic appearance of appendix and histopathology results of ovarian mucinous tumors and the stage of ovarian cancer with appendix tumoral involvement.
Materials and Methods: This descriptive, cross sectional study was conducted for inquiring about patients with pathologic diagnosis of ovarian and appendix mucinous tumors who had undergone surgery from 2010 to 2016 in Alzahra teaching hospital. Data were collected through a questionnaire and then analyzed.
Results: This study was done on 257 patients with definite diagnosis of ovarian and appendix mucinous tumors. 121 patients had undergone appendectomy and 110 cases of them had normal macroscopic appearance of appendix. Furthermore, 98.2% of patients with grossely normal looking appendix had normal pathology results and 63.6% of patients with abnormal looking appendix had abnormal pathology results. 5.9% of patients with borderline and 30% of invasive ovarian mucinous tumors had affected appendix. 4 of them were at stage III and 2 cases were at stage IV.
Conclusion: Appendectomy during ovarin tumor surgery is only recommended in cases with abnormal macroscopic appearance of appendix and at advanced stages of ovarian mucinous cancer.
