Radiographic Parameters in Predicting Outcome of Patients with Hepatocellular Carcinoma Treated with Yttrium-90 Microsphere Radioembolization

Table 6

Multivariate analysis of response after treatment and overall survival in patients with hepatocellular carcinoma treated with selective internal radiotherapy with Yttrium-90 microspheres*.

Favorable response after SIRT^†	Hazard ratio; (95% confidence interval)	𝑃-value
Overall survival	8.2 (0.93, 73.0)	0.027

^∗𝑁=9 patients. Response graded by Morphology, Attenuation, Size, and Structure (MASS) criteria.
^†SIRT: selective internal radiotherapy. MASS criteria were not included in this multivariate analysis because of the small number of patients who could be evaluated by MASS criteria.
