Purpose To evaluate safety and efficacy of combined transarterial chemoembolization (TACE) with doxorubicin-eluting beads (DEB) and sorafenib in patients with advanced hepatocellular carcinoma (HCC). Patients and Methods A prospective single-center phase II study was undertaken involving patients with unresectable HCC. The protocol involved sorafenib 400 mg twice per day combined with DEB-TACE. Safety and response were assessed. Results DEB-TACE in combination with sorafenib was successfully administered in 35 patients: mean age, 63 years; Child’s A, 89%; Barcelona Clinic Liver Cancer stage C, 64%; Eastern Cooperative Oncology Group performance status of 0 and 1, 46% and 54%, respectively; and mean index tumor size, 7.7 cm (standard deviation, ± 4.2 cm). Patients underwent 128 cycles of therapy (sorafenib plus DEB-TACE, 60 cycles; sorafenib alone, 68 cycles). Median number of cycles per patient was two (range, one to five cycles); median number of days treated with sorafenib was 71 (range, 4 to 620 days). The most common toxicities during cycle one were fatigue (94%), anorexia (67%), alterations in liver enzymes (64%), and dermatologic adverse effects (48%). Although most patients experienced at least one grade 3 to 4 toxicity, most toxicities were minor (grade 1 to 2, 83% v grade 3 to 4, 17%). Toxicity during cycle two was decreased. Over the course of the study, there were 40 sorafenib dose interruptions and 25 sorafenib dose reductions. Sorafenib plus DEB-TACE was associated with a disease control rate of 95% (Response Evaluation Criteria in Solid Tumors Group)/100% (European Association for the Study of the Liver [EASL]), with an objective response of 58% (EASL). Conclusion The combination of sorafenib and DEB-TACE in patients with unresectable HCC is well tolerated and safe, with most toxicities related to sorafenib. Toxicity is manageable with dose adjustment of sorafenib. Preliminary efficacy data are promising.

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.

PurposeRadiosurgery requires precise lesion localization. Fiducial markers enable lesion tracking, but complications from insertion may occur. The purpose of this study was to describe complications of fiducial marker insertion into pulmonary lesions.Materials and MethodsClinical and imaging records of 28 consecutive patients with 32 lung nodules or masses who underwent insertion of a total of 59 fiducial markers before radiosurgery were retrospectively reviewed.ResultsEighteen patients (67%) developed a pneumothorax, and six patients (22%) required a chest tube. The rates of pneumothorax were 82% and 40%, respectively, when 18-gauge and 19-gauge needles were used for marker insertion (P = 0.01). Increased rate of pneumothorax was also associated with targeting smaller lesions (P = 0.03) and tumors not in contact with the pleural surface (P = 0.04). A total of 11 fiducials (19%) migrated after insertion into the pleural space (10 markers) or into the airway (1 marker). Migration was associated with shorter distances from pleura to the marker deposition site (P = 0.04) and with fiducial placement outside of the target lesion (P = 0.03).ConclusionFiducial marker placement into lung lesions is associated with a high risk of pneumothorax and a risk of fiducial migration.
