Lenalidomide for second-line treatment of advanced hepatocellular cancer: a Brown University oncology group phase II study.

PURPOSE: To assess the activity and toxicity of lenalidomide for patients with advanced hepatocellular cancer (HCC) previously treated with sorafenib. MATERIALS AND METHODS: Patients with advanced HCC who progressed on or were intolerant to sorafenib were eligible. Patients received lenalidomide 25 mg orally for 1 to 21 days in a 28-day cycle until disease progression or unacceptable toxicities. RESULTS: Forty patients were enrolled and were classified according to the Child-Pugh score: 19 were Child-Pugh A, 16 patients were Child-Pugh B, and 5 were Child-Pugh C. Seventeen patients had extrahepatic disease. Grade 4 neutropenia occurred in 1 of 40 patients (2.5%). Grade 3 fatigue (n=3) and rash (n=4) were the most common nonhematologic toxicities attributable to lenalidomide. Six of 40 patients (15%) had a partial response. Two patients (5%) have not progressed at 36 and 32 months. The median progression-free survival was 3.6 months and the median overall survival was 7.6 months. CONCLUSIONS: Lenalidomide can be administered to patients with advanced HCC and hepatic dysfunction. Promising, and in a small percentage of patients, durable activity has been demonstrated. Investigations are needed to explore the mechanism of action of lenalidomide in HCC.

Erlotinib and chemoradiation followed by maintenance erlotinib for locally advanced pancreatic cancer: a phase I study.

OBJECTIVES: A phase I trial was conducted to determine the maximally tolerated dose of erlotinib with concurrent gemcitabine, paclitaxel, and radiation for patients with locally advanced pancreatic cancer and to gather preliminary data on maintenance erlotinib after chemoradiation. METHODS: Patients received gemcitabine, 75 mg/m2, and paclitaxel, 40 mg/m, weekly for 6 weeks with 50.4 radiation to the primary tumor and draining lymph nodes with a 2- to 3-cm margin. Erlotinib was administered over 3-dose levels (50-100 mg/d) with chemoradiation then all patients received 150 mg/d maintenance until disease progression. RESULTS: Seventeen patients were assessable for toxicity; 13 with locally advanced disease and 4 who had undergone resection but had positive margins. At erlotinib dosages > or =75 mg/d with chemoradiation the dose-limiting toxicities were diarrhea, dehydration, rash, myelosuppression, and small bowel stricture. Maintenance erlotinib, 150 mg/d, was well tolerated. The median survival of the 13 patients with locally advanced disease was 14.0 months and 6 of 13 (46%) had a partial response. CONCLUSIONS: The maximum tolerated dose of erlotinib with gemcitabine, paclitaxel and concurrent radiation is 50 mg/d for patients with locally advanced pancreatic cancer. Full dose maintenance erlotinib is well tolerated. Promising preliminary activity and overall survival were demonstrated.
