The disease progression rate (DPR) was significantly higher in patients with uterine adenosarcoma compared with those with cervical adenosarcoma (28.1% vs. 4.8%). The curve of progression-free survival significantly differed. For those with cervical adenosarcoma, the presence of a tumor stalk was a protective factor, whereas heterologous elements (HE) presented a risk factor for disease progression. For those with uterine adenosarcoma, the presence of a tumor stalk was an independent protective factor, whereas lymphovascular space invasion (LVSI) was an independent risk factor for disease progression. Moreover, HE was an independent risk factor for mortality. Fertility-sparing surgery (FSS) was performed in four and five patients with cervical and uterine adenosarcoma, respectively. Regarding FSS, combined with cases in previous studies, the DPR of patients with uterine adenosarcoma was relatively higher compared with those with cervical adenosarcoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We found that cervical adenosarcoma had a better prognosis than uterine adenosarcoma. The presence of a tumor stalk was a protective factor, whereas HE and LVSI were risk factors for prognosis. For those with uterine adenosarcoma, if FSS was administered, robust evaluation would be necessary. The small sample size limits the ability to make any strong conclusions about FSS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Implications for Practice<\/jats:title><jats:p>Uterine cervical adenosarcoma had a better prognosis than uterine adenosarcoma.
