Background: Data on infiltrating hepatocellular carcinoma (HCC) are limited. We sought to define treatment and outcome of patients treated with infiltrating HCC compared with patients who had advanced multifocal HCC. Methods: Between January 2000 and July 2011, a total of 147 patients with advanced HCC were identified from the Johns Hopkins Hospital database (infiltrative, n = 75; multifocal, n = 72). Clinicopathologic data were compared by HCC subtype. Results: Patients with infiltrating HCC had higher alfafetoprotein levels (median infiltrative, 326.5 ng/mL vs. multifocal, 27.0 ng/mL) and larger tumors (median size, infiltrating, 9.2 cm vs. multifocal, 5.5 cm) (P <0.05). Imaging failed to reveal a discrete lesion in 42.7 % of patients with infiltrating HCC. Most infiltrating HCC lesions presented as hypointense on T1-weighted images (55.7 %) and hyperintense on T2-weighted images (80.3 %). Among patients with infiltrating HCC, most (64.0 %) were treated with intra-arterial therapy (IAT), and periprocedural morality was 2.7 %. Patients treated with IAT had longer survival versus patients receiving best support care (median survival, IAT, 12 months vs. best supportive care, 3 months; P = 0.001). Survival after IAT was similar among patients treated with infiltrating HCC versus multifocal HCC (hazard ratio 1.29, 95 % confidence interval 0.82-2.03; P = 0.27). Among infiltrating HCC patients, pretreatment bilirubin ≥2 mg/dL and alfa-fetoprotein > 400 ng/mL were associated with worse survival after IAT (P < 0.05). Patients with progressive disease after IAT had higher risk of death versus patients who had stable/responsive disease (hazard ratio 3.53, 95 % confidence interval 1.49-8.37; P = 0.004). Conclusions: Patients with infiltrative HCC often present without a discrete lesion on imaging. IAT for infiltrative HCC was safe and was associated with survival comparable to IAT outcomes for patients with multifocal HCC. Infiltrative HCC morphology is not a contraindication to IAT therapy in select patients.
