Background
Treatment with yttrium-90 (Y90) microspheres has emerged as a viable liver-directed therapy for patients with unresectable tumors and those outside transplantation criteria. A select number of patients demonstrate a favorable response and become candidates for surgical resection.
Methods
Patients who underwent selective internal radiation therapy (SIRT) with Y90 microspheres at two institutions were reviewed. Patients who underwent liver resection were included in the study. The data gathered included demographics, tumor characteristics, response to Y90, surgical details, perioperative outcomes, and survival.
Results
The inclusion criteria were met by 12 patients. The diagnoses included metastatic disease from colorectal adenocarcinoma (n = 6), neuroendocrine tumor (n = 1), and ocular melanoma (n = 1) in addition to hepatocellular carcinoma (n = 4). The median time from liver disease diagnosis to Y90 treatment was 5.5 months (range 2–92 months). The median time from Y90 treatment to surgery was 9.5 months (range 3–20 months). The surgical approach included right hepatectomy (n = 3), extended right hepatectomy (n = 5), extended left hepatectomy (n = 1), segmentectomy with ablation (n = 2), and segmentectomy with isolated liver perfusion (n = 1). The hospital stay was 7 days (range 4–31 days), and 67% of the patients were discharged home. The readmission rate was 42%. The 90-day morbidity and mortality rates were respectively 42 and 8%. At this writing, the median overall survival has not been reached at 25 months.
Conclusion
Liver resection after Y90 SIRT is a challenging surgical procedure with high rates of perioperative morbidity and hospital readmission. However, for properly selected patients, potential exists for extending disease-free and overall survival in the current era of multimodal therapy for malignant liver disease.
