ABSTRACT
BACKGROUND:
The primary goal of this study was to determine overall survival (OS) in patients who underwent local treatment (metastasectomy or stereotactic body radiotherapy [SBRT]) or systemic therapy (chemotherapy or targeted therapy) for oligometastatic esophagogastric cancer. The secondary goal was to determine prognostic factors for OS.METHODS:
Patients with synchronous or metachronous oligometastatic esophagogastric cancer who underwent local treatment or systemic therapy were included in this single-center, retrospective cohort study. Oligometastatic disease (OMD) included 1 organ or 1 extraregional lymph node station with ≤ 3 lesions. OS was determined after OMD detection. Treatment for OMD was categorized as (1) local treatment, (2) local plus systemic, (3) systemic therapy. The primary tumor was controlled after resection or definitive chemoradiotherapy.RESULTS:
In total, 85 patients were included. Treatment for OMD was local treatment (58%), local plus systemic (14%), or systemic therapy (28%). The primary tumor was controlled in 68% of patients. Most patients were diagnosed with distal esophageal cancer (61%), with adenocarcinoma histology (76%), and presented with synchronous OMD (51%). OS after local treatment was 17 months (95% confidence interval [CI] 12-40), after local plus systemic therapy 35 months (95% CI 29-NA), and after systemic therapy 16 months (95% CI 11-NA). Better OS was independently associated with local plus systemic compared with local treatment (hazard ratio [HR] 2.11, 95% CI 1.05-5.07) or systemic therapy (HR 2.28, 95% CI 1.04-6.07).CONCLUSIONS:
Local plus systemic therapy for oligometastatic esophagogastric cancer was independently associated with improved OS and better OS compared with either systemic therapy or local treatment.
