Abstract
RUIZ-ECHEVERRIA MD, Franco Rafael et al. Uterine collision tumor. Case report and review of he literature. Rev. colomb. obstet. ginecol. [online]. 2023, vol.74, n.3, pp.225-236. Epub Sep 30, 2023. ISSN 0034-7434. https://doi.org/10.18597/rcog.4011.
Objectives:
To report the case of a patient with a uterine collision tumor and to conduct a review of the literature.
Material and methods:
A 76-year-old patient who presented to the national cancer referral center in Bogota (Colombia), where she was diagnosed with a uterine collision tumor consisting of a serous-type endometrial adenocarcinoma and a cervical adenosarcoma. The patient underwent surgical treatment followed by chemotherapy and supplemental radiotherapy, and died 16 months later. A search was conducted in the Medline via PubMed and Embase databases, including reports and case series of women with a diagnosis of uterine collision tumor, with retrieval of information regarding diagnosis, treatment and prognosis. A narrative summary of the findings was made.
Results:
The search identified 36 titles, of which 14 studies with 17 patients were included. The most frequent histopathological diagnosis was endometrial adenocarcinoma and high and low grade endometrial sarcoma (47 %). Primary treatment was surgery and adjuvant treatment with chemotherapy and radiotherapy (15 %) was performed in close to 50 % of cases. One-year survival was 75 %.
Conclusions:
No cases of uterine collision tumors with the histopathology or in the location of the reported case were found in the literature. If this reported case is taken into account, 2-year mortality is 28 %. Further studies to describe the immunohistochemistry, treatment and prognosis of this condition are needed.
