Sorafenib plus low-dose cisplatin and fluorouracil hepatic arterial infusion chemotherapy versus sorafenib alone in patients with advanced hepatocellular carcinoma (SILIUS): a randomised, open label, phase 3 trial.

BACKGROUND: Hepatic arterial infusion chemotherapy plus sorafenib in phase 2 trials has shown favourable tumour control and a manageable safety profile in patients with advanced, unresectable hepatocellular carcinoma. However, no randomised phase 3 trial has tested the combination of sorafenib with continuous arterial infusion chemotherapy. We aimed to compare continuous hepatic arterial infusion chemotherapy plus sorafenib with sorafenib alone in patients with advanced, unresectable hepatocellular carcinoma. METHODS: We did an open-label, randomised, phase 3 trial (SILIUS) at 31 sites in Japan. Eligible patients were aged 20 years or older, with advanced hepatocellular carcinoma not suitable for resection, local ablation, or transarterial chemoembolisation; Eastern Cooperative Oncology Group (ECOG) performance status 0-1; Child-Pugh score 7 or lower; and adequate bone marrow, liver, and renal function. Patients were randomly assigned (1:1) via an interactive web response system with a computer-generated sequence to receive 400 mg sorafenib orally twice daily or 400 mg sorafenib orally twice daily plus hepatic arterial infusion chemotherapy (cisplatin 20 mg/m2 on days 1 and 8 and fluorouracil 330 mg/m2 continuously on days 1-5 and 8-12 of every 28-day cycle via an implanted catheter system). The primary endpoint was overall survival. The primary efficacy analysis comprised all randomised patients (the intention-to-treat population), and the safety analysis comprised all randomised patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov, number NCT01214343. FINDINGS: Between Nov 4, 2010, and June 10, 2014, 206 patients were randomly assigned (103 to the sorafenib group, 103 to the sorafenib plus hepatic arterial infusion chemotherapy group). One patient in the sorafenib plus hepatic arterial infusion chemotherapy group withdrew after randomisation. Median overall survival was similar in the sorafenib plus hepatic arterial infusion chemotherapy (n=102) and sorafenib monotherapy (n=103) groups (11·8 months [95% CI 9·1-14·5] vs 11·5 months [8·2-14·8]; hazard ratio 1·009 [95% CI 0·743-1·371]; p=0·955). Grade 3-4 adverse events that were more frequent in the sorafenib plus hepatic arterial infusion chemotherapy group than in the sorafenib monotherapy group included anaemia (15 [17%] of 88 vs six [6%] of 102), neutropenia (15 [17%] vs one [1%]), thrombocytopenia (30 [34%] vs 12 [12%]), and anorexia (12 [14%] vs six [6%]). INTERPRETATION: Addition of hepatic arterial infusion chemotherapy to sorafenib did not significantly improve overall survival in patients with advanced hepatocellular carcinoma.

Risk factors for sodium valproate-induced renal tubular dysfunction.

OBJECTIVE: To explore the risk factors for the development of sodium valproate (VPA)-induced renal tubular dysfunction for early diagnosis and treatment. STUDY DESIGN: The subjects were selected from patients who were diagnosed with epilepsy and administered VPA. Blood and spot urine samples were collected and measured the concentration of VPA, the level of serum phosphorus, serum uric acid, serum free carnitine, serum cystatin-c, and urine ß2-microglobulin (BMG). Patients with urine BMG/creatinine levels above 219.2 were treated as renal proximal tubular dysfunction (RTD), with all others treated as non-RTD. RESULTS: Eighty-seven patients, 4-48 years, 53 men and 34 women, were studied. RTD group is 17 patients and non-RTD group is 70 patients. Univariate analyses revealed that the RTD patients were more likely to be bedridden, receiving enteral tube feeding, taking more anticonvulsants, and demonstrating significantly lower serum levels of free carnitine, uric acid, and phosphorus. Among them, bedridden, free serum carnitine, and phosphorus levels were associated with the development of RTD by multivariate analysis. CONCLUSIONS: Bedridden patients receiving VPA are susceptible to hypocarnitinemia, which can cause RTD and may lead to FS. Therefore, urinary BMG should be measured regularly in all patients receiving VPA to assess renal tubular function. An additional measurement of serum free carnitine level should be considered in patients who developed RTD. Supplementation of carnitine for those patients to prevent such complication deserves for further study.

Turner syndrome associated with ulcerative colitis.

UNLABELLED: We report the case of a 7-yr-old girl with Turner syndrome, ulcerative colitis (UC) and coarctation of the aorta. The diagnosis of Turner syndrome was made in early infancy (karyotype analysis 45, X). Growth hormone treatment was started at 3 yr and 2 mo of age. From the age of 4 yr and 5 mo, the patient suffered from persistent diarrhea with traces of blood and intermittent abdominal discomfort. As these symptoms gradually deteriorated, she was referred to our clinic at the age of 7 yr for further evaluation. Barium enema showed aphtha and loss of the fine network pattern in the descending colon and rectum. An endoscopic examination showed ulceration, edema, friability, and erythema beginning in the rectum and extending up to the splenic flexure of the descending colon. The histology of the descending colon area showed severe stromal infiltration of inflammatory cells. These endoscopic findings and the histological findings were consistent with UC. Thus, based on these findings, the patient was diagnosed as having UC. Mesalazine therapy was initiated at this time. The patient is currently being treated with mesalazine (1,000 mg/day) and abdominal symptoms and bloody diarrhea have disappeared. GH therapy was not interrupted during the therapy for UC. Retrospectively, growth hormone improved growth velocity (9 cm/year) during the first year of treatment, however from the age of 4 yr, growth velocity decreased (4-5 cm/yr) in spite of the GH treatment. CONCLUSION: Patients with Turner syndrome and gastrointestinal symptoms should be investigated for inflammatory bowel diseases. Growth velocity is useful for evaluating the presence of inflammatory bowel diseases and other systemic diseases.
