Resumen
VALDESPINO-CASTILLO, Víctor Edmundo et al. Cystic teratoma with malignant transformation: Series of cases. Ginecol. obstet. Méx. [online]. 2020, vol.88, n.3, pp.154-160. Epub 30-Ago-2021. ISSN 0300-9041. https://doi.org/10.24245/gom.v88i3.3561.
OBJECTIVE:
Describe the clinical and histopathological characteristics of cases of mature teratoma with malignant transformation, its treatment and survival.
MATERIALS AND METHODS:
Retrospective, cross-sectional and observational study conducted between January 2014 and December 2018 in a gynecological oncology service. Study parameters: pathological stage of the tumor, concentrations of Ca 125, survival and treatment. The sample size did not allow statistical tests to be applied.
RESULTS:
147 patients with a diagnosis of mature teratoma were studied of these 4 underwent malignant transformation to squamous cell carcinoma and 18 were ruled out due to incomplete information. The transoperative histopathological study identified 3 of the 4 ovarian tumors as malignant. Fertility conservative surgeries were not performed because in none of the cases was it necessary. In 3 of the 4 mature teratomas with malignant transformation, adjuvant chemotherapy scheme was indicated. All patients remain alive and have no relapse so far.
CONCLUSIONS:
The histopathological transoperatory study is absolutely necessary for an ovarian tumor, even in cystic ovarian tumors. Carefully management of ovarian tumors is very important, we should prevent a rupture of the malignant tumor because this changes the surgical stage and the prognosis. The surgical and medical treatment of infrequent tumor-like mature teratoma with malignant transformation improves survival and avoid sub treatments or overtreatment.
