ABSTRACT
BACKGROUND: Endobiliary stenting is standard practice for palliation of obstructive jaundice due to biliary tract cancer (BTC). Photodynamic therapy (PDT) may also improve biliary drainage and previous small studies suggested survival benefit. AIMS: To assess the difference in outcome between patients with BTC undergoing palliative stenting plus PDT versus stenting alone. METHODS: 92 patients with confirmed locally advanced or metastatic BTC, ECOG performance status 0-3 and adequate biliary drainage were randomised (46 per group) to receive porfimer sodium PDT plus stenting or stenting alone. The primary end point was overall survival (OS). Toxicity and progression-free survival (PFS) were secondary end points. Treatment arms were well balanced for baseline factors and prior therapy. RESULTS: No significant differences in grade 3-4 toxicities and no grade 3-4 adverse events due to PDT were observed. Thirteen (28%) PDT patients and 24 (52%) stent alone patients received subsequent palliative chemotherapy. After a median follow-up of 8.4 months, OS and PFS were worse in patients receiving PDT compared with stent alone group (OS median 6.2 vs 9.8 months (HR 1.56, 95% CI 1.00 to 2.43, p=0.048) and PFS median 3.4 vs 4.3 months (HR 1.43, 95% CI: 0.93 to 2.18, p=0.10), respectively). CONCLUSION: In patients with locally advanced or metastatic BTC, PDT was associated with worse outcome than stenting alone, explained only in part by the differences in chemotherapy treatments. We conclude that optimal stenting remains the treatment of choice for malignant biliary obstruction and the use of PDT for this indication cannot be recommended outside of clinical trials.

ABSTRACT
AIMS: Sorafenib is the only standard therapy for advanced hepatocellular carcinoma, but has a low response rate. Leucovorin and oxaliplatin (FOLFOX) has a superior response rate versus doxorubicin among Asian sorafenib-naive patients. We aimed to retrospectively review the outcome of 20 consecutive patients treated with FOLFOX at a single European center. MATERIALS & METHODS: Patients had symptomatic disease burdens unlikely to regress with sorafenib or had no proven treatment options (sorafenib-refractory or recurrence post liver transplantation). RESULTS: One sorafenib-refractory patient had a complete response and two liver transplant patients experienced partial responses. Median overall survival was 6.3 months. There was one chemotherapy death due to neutropenic sepsis. CONCLUSION: In advanced hepatocellular carcinoma, FOLFOX can induce clinically relevant responses, but needs prospective validation.
