Abstract
Purpose
This prospective pilot single-institution study was undertaken to document the feasibility, safety, and efficacy of treatment of liver-dominant metastatic gastrointestinal cancer using 90Y glass microspheres.
Methods
Between June 2010 and November 2012, 30 adult patients (22 men, eight women; median age 61 years) with metastatic chemotherapy-refractory unresectable colorectal (n = 15), neuroendocrine (n = 9), intrahepatic cholangiocarcinoma (n = 3), pancreas (n = 2), and esophageal (n = 1) carcinomas underwent 45 lobar or segmental administrations of 90Y glass microspheres. Data regarding clinical and laboratory adverse events (AE) were collected prospectively for 6 months after each treatment. Radiographic responses were evaluated using Response Evaluation Criteria in Solid Tumors, version 1.1. Time to maximum response, response duration, progression-free survival (hepatic and extrahepatic), and overall survival were measured.
Results
Median target dose and activity were 111.6 Gy and 2.5 GBq per treatment session, respectively. All but three clinical AE were grade 1 or 2 in severity. Serious AE included an unplanned hospital admission for carcinoid crisis, grade 3 vomiting, and grade 4 gastric ulcer. Patients with colorectal cancer had hepatic objective response rate (ORR) of 27 % and a disease control rate (DCR) of 73 %. Median progression-free and overall survival were 1.0 and 4.9 months, respectively. Patients with neuroendocrine tumors had hepatic ORR and DCR of 78 % and 100 %, respectively. Median progression-free survival was 18.5 months for this cohort.
Conclusions
Y glass microspheres device has a favorable safety profile and achieved prolonged disease control of hepatic tumor burden in a subset of patients, including all patients enrolled in the neuroendocrine cohort.
