Purpose: To evaluate safety and activity of perifosine and sorafenib combination therapy in patients with lymphoproliferative diseases.Experimental Design: Patients with relapsed and refractory lymphoproliferative diseases received perifosine (50 mg twice daily) for 1 month. Patients achieving less than partial response (PR) after perifosine alone were administered the combination therapy [perifosine plus sorafenib (400 mg twice daily)] until progressive disease (PD) or unacceptable toxicity occurred. The pERK and pAKT in peripheral blood lymphocytes as well as serum cytokine levels were investigated as predictive biomarkers of response.Results: Forty patients enrolled in this study. After 1 month of perifosine alone, 36 who achieved less than PR went on to combination therapy, whereas four patients with chronic lymphocytic leukemia (CLL) who achieved PR continued with perifosine alone for a median of 10 months (range, 4–21). The most common drug-related toxicities were grade 1–2 anemia (17%), thrombocytopenia (9%), diarrhea (25%), joint pain (22%), and hand–foot skin reaction (25%). Three patients experienced grade 3 pneumonitis. Eight patients (22%) achieved PR, 15 (42%) achieved stable disease, and 13 (36%) experienced PD. A 28% PR rate was recorded for 25 patients with Hodgkin lymphoma. Among all patients, median overall survival and progression-free survival were 16 and 5 months, respectively. Early reductions in pERK and pAKT significantly correlated with the probability of clinical response.Conclusions: Perifosine and sorafenib combination therapy is feasible with manageable toxicity and demonstrates promising activity in patients with Hodgkin lymphoma. The predictive value of pERK and pAKT should be confirmed in a larger patient cohort. Clin Cancer Res; 20(22); 5641–51. ©2014 AACR.

Primary hepatocellular carcinoma is the commonest cancer in The Gambia. The Gambia Hepatitis Intervention Study (GHIS) was established in 1986 to evaluate the protective effectiveness of infant hepatitis B immunization in the prevention of chronic liver disease, particularly, hepatocellular carcinoma and cirrhosis later in adult life. This program was designed based on a series of assumptions. Here, we used data from observational and epidemiologic studies developed since 1986 to examine the validity of these assumptions. We found that (a) hepatitis B vaccine coverage was 15% more than originally assumed, (b) protection against hepatitis B virus (HBV) infection was not dependent on the number of vaccine doses received, (c) perinatal infection with HBV was of negligible importance, and (d) the HBV attributable risk of hepatocellular carcinoma at age
