Abstract
To validate the oncological safety of fertility preservation in malignant ovarian germ cell tumors (MOGCTs) and to define the significance of maximal cytoreduction in early stage MOGCTs. Sixty-nine patients with stage I and II MOGCTs who underwent surgical treatment were included in the study. Fertility-sparing surgery is defined as conservative surgery and hysterectomy and contralateral salpingo-oophorectomy were defined as definitive surgery. Both surgical approaches involved lymphadenectomy and omentectomy. Most patients received platinum-based combinations for adjuvant therapy. Survival outcomes of the conservative surgery group were compared with the definitive surgery group. Median age of the study group was 21 years (range: 12-40 years). Median tumor size measured 150 mm (range, 20-300 mm). Surgery type (conservative surgery vs. definitive surgery) and lymphadenectomy (performed vs. not performed) were insignificant for the recurrence (p = 0.758, p = 0.271). However, surgical outcome (maximal vs. optimal and suboptimal) and type of tumor (dysgerminoma vs. nondysgerminoma) determined the recurrence (p = 0.001, p = 0.021). Fertility-conserving approach is safe in early stage MOGCTs. However, maximal cytoreduction should be achieved in this group of patients, without conceding fertility-conserving approach. On the other hand, development of chemotherapy options with less gonadotoxic effects, but equal or stronger efficiency in comparison with platinum-based chemotherapy, will certainly facilitate management of this patient group.
