A multicenter Phase II study of sorafenib in Japanese patients with advanced hepatocellular carcinoma and Child Pugh A and B class.

OBJECTIVE: To evaluate prospectively the efficacy and safety of sorafenib, which has been the first-line treatment for advanced hepatocellular carcinoma (HCC), in Japanese HCC patients (pts) with not only Child-Pugh (C-P) A class but also C-P B class. METHODS: Sorafenib was administered orally at the dose of 400 mg twice daily for pts with HCC and liver function of C-P score of 5-8. Administration was continued until the detection of disease progression or appearance of unacceptable toxicity. The primary endpoint was time to progression (TTP), and toxicity and the secondary endpoints included objective response, overall survival (OS). RESULTS: Forty C-P A pts and 12 C-P B pts were enrolled. The median TTP in the C-P A pts and C-P B pts was 3.3 months and 3.2 months, respectively. Among the pts with C-P A, complete response, partial response, and stable disease were achieved for 2.5%, 7.5% and 47.5%. Among the pts with C-P B, there were no treatment responses, 66.7% of pts had stable disease. The median OS in the C-P A pts and C-P B pts was 13.4 months and 7.4 months, respectively. With regard to toxicities, fewer C-P A pts experienced Grade 3/4 toxicities than C-P B pts (77.5% vs. 91.6%). There were no treatment-related deaths in either group of patients. CONCLUSIONS: This study shows sorafenib has similar effectiveness in the recent post-approval studies and is well-tolerated in Japanese pts with HCC and Child Pugh A class. Sorafenib should be used with great care for Child Pugh class B pts.

Direct spraying of shakuyakukanzoto onto the duodenal papilla: a novel method for preventing pancreatitis following endoscopic retrograde cholangiopancreatography.

BACKGROUND/AIMS: Topical epinephrine application to the duodenal papilla reduces spasm of the sphincter of Oddi and prevents acute pancreatitis following endoscopic retrograde cholangiopancreatography (ERCP). Shakuyakukanzoto (TJ-68) has an inhibitory effect on muscle contraction. Therefore, TJ-68 potentially allows the relaxation of the sphincter of Oddi, which can aid in the prevention of post-ERCP pancreatitis. METHODS: Thirty-six patients planned for ERCP were divided into TJ-68 (n = 17) and control groups (n = 19). In the TJ-68 group, the TJ-68 solution was endoscopically sprayed directly onto the duodenal papilla of patients. To assess the effects of TJ-68, serum amylase levels were measured at 1 h and 1 day after ERCP and symptoms were evaluated. RESULTS: The serum amylase levels at 1 h after ERCP were 273.6 ± 212.0 IU/l in the TJ-68 group and 428.7 ± 281.6 IU/l in the control group, showing a statistically significant difference (p = 0.036). The serum amylase levels at 24 h after ERCP were 230.0 ± 182.7 IU/l in the TJ-68 group and 497.4 ± 514.0 IU/l in the control group (p = 0.011). Post-ERCP pancreatitis was observed in 0 and 4 patients (21.1%) in the TJ-68 and control groups, respectively, which was not statistically significant (p = 0.11). CONCLUSION: Direct TJ-68 solution application to the duodenal papilla significantly inhibited the elevation of serum amylase levels. However, the preventive effect regarding post-ERCP pancreatitis was not confirmed in this study.

Preventive effect of traditional Japanese medicine on neurotoxicity of FOLFOX for metastatic colorectal cancer: a multicenter retrospective study.

BACKGROUND: A combination of 5-fluorouracil/folinic acid plus oxaliplatin (FOLFOX) is a standard regimen for the chemotherapy of metastatic colorectal cancer. The major dose-limiting toxic effect of oxaliplatin is neurotoxicity. The aim of this study was to evaluate the preventive effects of traditional Japanese medicines, goshajinkigan and shakuyakukanzoto on oxaliplatin-induced neurotoxicity with FOLFOX. PATIENTS AND METHODS: Between July 2006 and November 2008, a total of 44 patients with metastatic colorectal cancer received modified FOLFOX6 or FOLFOX4, as first-line chemotherapy at three institutions. They concurrently received either goshajinkigan (group A, n=20) or shakuyakukanzoto (group B, n=24) for neurotoxicity reduction. RESULTS: The median number of treatment cycles and the median cumulative dose of oxaliplatin were 12 cycles (range, 4-19) and 898 mg/m(2) (range, 340-1255) in group A and 10.5 cycles (range, 6-20) and 845 mg/m(2) (range, 510-1480) in group B. Eighteen patients in group A and 24 in group B received oxaliplatin in a cumulative dose exceeding 500 mg/m(2). At a dose of 500 mg/m(2) oxaliplatin, grade 1-2 toxicity occurred in 10 patients of group A and in 7 of group B, but there was no grade 3 or higher toxicity in either group. The response rate of the 38 patients with measurable lesions was 50.0% (9/18) in group A and 65% (13/20) in group B. CONCLUSION: The administration of traditional Japanese medicine may reduce oxalipatin-induced neurotoxicity without negatively affecting tumor response in patients with colorectal cancer who undergo FOLFOX therapy.
