Pulmonary metastasis from endometrial carcinoma

Area of Science:

• Oncology
• Pulmonary Medicine
• Gynecologic Oncology

Background:

• Endometrial adenocarcinoma can metastasize to the lungs, impacting patient prognosis.
• Understanding predictors of survival in patients with pulmonary metastasis (PM) is crucial for clinical management.

Purpose of the Study:

• To investigate the clinical features of pulmonary metastasis (PM) from endometrial adenocarcinoma.
• To identify predictors of prolonged survival following the detection of PM.

Main Methods:

• Retrospective study of 15 patients with pulmonary metastasis from endometrial adenocarcinoma.
• Evaluation of PM using chest computed tomography (CT) scans.
• Analysis of clinical features, metastasis distribution, and time to recurrence in relation to survival.

Main Results:

• Patients with bilateral PM or lymphangitic spread often had concurrent metastases in other sites.
• A limited number (≤5) of unilateral nodules was associated with significantly longer median survival (50 months) compared to bilateral PM (7 months).
• Pulmonary recurrence detected more than 2 years after initial therapy correlated with significantly longer survival (31 months) versus recurrence within 2 years (10 months).

Conclusions:

• CT-determined distribution of pulmonary metastasis is a key predictor of survival.
• The time interval between initial therapy and PM detection is a significant prognostic factor.
• Surgical treatment for limited, unilateral nodules may improve survival outcomes.
