BACKGROUND: Uterine malignancies frequently metastasize to the lungs. Pulmonary metastasectomy has demonstrated survival benefits in some malignancies; however, its efficacy for uterine malignancies remains unclear.
METHODS: We retrospectively analyzed 38 patients who underwent pulmonary metastasectomy for uterine malignancies at the Kanagawa Cancer Center between 2010 and 2020. The primary endpoint was recurrence-free survival (RFS) after pulmonary resection.
RESULTS: The median patient age was 63 years. The primary sites were the cervical uteri (n = 22) and corpus uteri (n = 16). The FIGO stages at the time of treatment for the primary tumor were I, II, III, IV, and unknown in 20, 7, 9, 1, and 1 patient, respectively. The median disease-free interval (DFI), defined as the interval between primary treatment and first recurrence, was 26.5 months. Most patients had single metastasis (n = 32). The procedures for metastasectomy included lobectomy, segmentectomy, and wedge resection (n = 15, 8, and 15, respectively), and two cases resulted in microscopically incomplete resection. The median follow-up period after pulmonary metastasectomy was 57 months, with 16 patients experiencing recurrence after pulmonary metastasectomy (5-year RFS rate: 55.6%). Univariate analysis identified FIGO stage ≥ III, DFI < 12 months, presence of synchronous extrapulmonary recurrence, and uterine sarcoma as poor prognostic factors. No prognostic differences were found between cervical and corpus uteri cancers.
CONCLUSIONS: Pulmonary metastasectomy may confer prognostic benefits in patients with uterine malignancies. Careful consideration is warranted for patients with advanced-stage primary tumors, early recurrence after primary treatment, synchronous extrapulmonary recurrence, and uterine sarcoma.
