OBJECTIVE: Sorafenib is an oral multi-kinase inhibitor of Raf-1, VEGF and PDGF receptors and others, resulting in tumor regression and anti-angiogenesis. We studied serum pancreatic enzyme increase associated with sorafenib treatment.
PATIENTS AND METHODS: In a phase II study of Japanese patients with metastatic renal cell carcinoma, a total of 131 patients received sorafenib 400 mg twice per day. Serum levels of lipase and amylase were measured on day 7 and every 3-4 weeks thereafter during treatment period. When grade 3 or 4 enzyme abnormalities were observed, ultrasound or computed tomography scan was performed to detect pancreatitis.
RESULTS: The incidence of all-grades lipase and amylase increases were 55. 7% and 38. 2%, respectively, while those of grade 3 or 4 were 30. 5% and 5. 3%, respectively. The majority of these events were observed in the first 3 weeks of sorafenib treatment. Grade 3 or 4 lipase increase was detected in 32 patients (24. 4%)on day 7 measurement. These abnormal elevations spontaneously resolved in all patients. Regarding grade 3 lipase increase, the median time to recovery to grade 2 and 1 were 7 and 14 days, respectively. Three patients required interruption of the treatment. No patient showed any clinical manifestation or abnormal imaging finding suggesting pancreatitis.
CONCLUSION: Pancreatic enzyme increases observed frequently under sorafenib treatment were transient and asymptomatic. They were not related to symptomatic pancreatitis.
