Background. Epithelial ovarian cancer (EOC) accounts for 25% of all malignancies in the female genital tract and it is the most common cause of death among women who develop gynecologic malignancies. According to recent reports at least 20% of EOC are diagnosed at stage I of the disease. Because women tend to give birth to their first child at an older age, and due to the usage of more sensitive diagnostic procedures, the diagnosis of EOC during reproductive age has become more frequent. Therefore, the demand for fertility-sparing surgery in early-stage of EOC is increased. Case report. We presented the case of accomplished reproduction at 41 after the conservative treatment of mucinous ovarian cancer. In the absence of a complete surgical staging, her decision was to spare her fertility capacities opposed to the treatment recommendations of the oncological council. The bottom-line of this report was to give its contribution to the ongoing controversies in the decision to recommend the conservative surgical treatment of the EOC and also to reveal the need of reconsideration of the necessity of a complete surgical staging in patients with stage I of mucinous ovarian cancer. Conclusion. The profile of EOC cases in which a conservative surgical approach is the appropriate one has not yet been defined. Correct surgical staging is still an indispensable guideline for that kind of clinical decision. In the case of stage I of mucinous ovarian cancer with the low tumor grade, the necessity of a complete surgical staging should be reconsidered.
