Sorafenib use in hepatitis B virus- or hepatitis C virus-related hepatocellular carcinoma: A propensity score matching study.

Sorafenib is the recommended first-line treatment option for patients with advanced hepatocellular carcinoma (HCC). Hepatitis C virus (HCV)-related advanced HCC (HCV-HCC) seemed to have a better response than hepatitis B virus (HBV)-related HCC (HBV-HCC) in sorafenib use, but it was undetermined. Hence, we aimed to investigate the effect of sorafenib between HBV-HCC and HCV-HCC patients in Taiwan. From August 2012 to December 2016, 575 consecutive advanced HCC patients received sorafenib under the reimbursement of Taiwan national health insurance in our hospital. Radiologic assessment was performed at a 2-month interval. Those patients with tumor progression or liver function deterioration were disallowed for further sorafenib use. Patients with HBV or HCV infection were, retrospectively, enrolled and followed till December 2018. There were 277 (62.4%) HBV-HCC patients and 167 (37.6%) HCV-HCC patients. Before sorafenib, 192 (69.3%) HBV-HCC patients who had used nucleoside analogs (NAs) for HBV management, whereas only 5 (3%) HCV-HCC patients received interferon-based antiviral therapy. Overall survival (OS) of HCV-HCC patients was significantly superior to HBV-HCC patients without NAs (8.8 months vs. 4.9 months, p = 0.006), but was noninferior to HBV-HCC patients with NAs (8.8 months vs. 10.7 months, p = 0.54). Using propensity score matching, progression-free survival (2.0 months vs. 2.1 months, p = 0.374) and OS (10.5 months vs. 9.6 months, p = 0.746) between HBV-HCC and HCV-HCC groups were not different. Antiviral therapy might increase survival benefits of advanced HBV-HCC patients underwent sorafenib use, leading to a comparable OS to HCV-HCC patients in Taiwan.

Increased cumulative doses and appearance of hand-foot skin reaction prolonged progression free survival in sorafenib-treated advanced hepatocellular carcinoma patients.

Sorafenib has been recommended as a new palliative therapy for advanced hepatocellular carcinoma (HCC). However, the clinical outcome of patients receiving sorafenib therapy varies. This study sought to identify which clinical method could be used to predict clinical outcome of sorafenib monotherapy in patients with advanced HCC. A total of 146 advanced HCC patients with Child-Pugh A liver function were enrolled from June 2011 to September 2015. Sorafenib doses ranged from 200 mg once daily to 400 mg twice daily. Clinical and pathological parameters were collected. There was no predefined primary endpoint. Tumor response rate, adverse events, overall survival (OS), and progression-free survival (PFS) were analyzed. The follow-up period was 1718 days (median: 859 days). The median dosage of sorafenib was 562.35 mg.Forty patients (27.4%) had stable disease and 106 patients (72.6%) had progression disease. The OS was 432.21 ± 360.52 days (median: 329 days) and PFS was 167.05 ± 166.50 days (median: 102.5 days). No sorafenib toxic effect-related mortality was encountered. The most common severe adverse events (≧grade 3) were hand-foot skin reactions (HFSR) (16, 11.0%), diarrhea (7, 4.8%), and alopecia (1, 0.7%). The following patients had longer median PFS (mPFS): those receiving total dosage > 55000 mg (217 vs.63 days; HR = 0.20,95%CI = 0.11-0.38; p < 0.001), those receiving daily dosage <562 mg (140 vs.69 days; HR = 0.27, 95%CI = 0.17-0.46; p < 0.001), those with treatment durations > 112 days (231vs.64 days; HR = 0.37, 95%CI = 0.19-0.74; p < 0.001), and those with HFSR (105 vs.75 days; HR = 0.60,95% CI = 0.6-0.98; p = 0.04). In conclusion, increased cumulative doses of sorafenib as well as the appearance of HFSR were indicators of prolonged mPFS in sorafenib-treated advanced HCC patients.

The outcome of sorafenib monotherapy on hepatocellular carcinoma with portal vein tumor thrombosis.

Sorafenib is not recommended for advanced hepatocellular carcinoma (HCC) patients with Vp4 (portal invasion at the main trunk) by the Japan Society of Hepatology (JSH) due to a risk of hepatic failure. This study aimed to elucidate the safety and efficacy of sorafenib monotherapy on HCC with macro-vascular invasion (MVI). A total of 415 consecutive advanced HCC patients received sorafenib in our hospital. Patients with only MVI and sorafenib monotherapy were retrospectively enrolled. We enrolled 113 (27.2%) patients, including 56 (49.5%) Vp3 (portal invasion at the first branch) and 57 (50.5%) Vp4. Their median intervals of follow-up and sorafenib-use were 7.8 months and 2.7 months respectively. Using sorafenib, more Vp4 had hepatic decompensation (HD) (37% VS 18.2%, p = 0.028) than Vp3 patients. The multivariate analysis showed Vp4 (Odds ratio: 2.91; 95% CI: 1.02-8.3, p = 0.041) and baseline alpha-fetoprotein (AFP) ≥ 200 ng/ml were associated with HD. Dividing our patients into four subgroups as Vp3 + AFP < 200 ng/ml, Vp3 + AFP ≥ 200 ng/ml, Vp4 + AFP < 200 ng/ml and Vp4 + AFP ≥ 200 ng/ml, the proportions of HD were 16.7%, 19.4%, 16.7% and 55.2% respectively (p = 0.002). The overall survival rates were distributed with a significant decreasing trend as 10.2 ± 4.4 months, 6.5 ± 1.0 months, 6.0 ± 1.3 months and 2.5 ± 0.5 months (p = 0.001). We found only Vp4 plus AFP ≥ 200 ng/ml could induce more HD and a poorer prognosis than Vp3 patients. Hence, in Vp4 patients with higher AFP, sorafenib should not be the first-line treatment due to its limited survival benefit.

Albumin-Bilirubin grade predicts prognosis of HCC patients with sorafenib use.

BACKGROUND AND AIM: The Albumin-Bilirubin (ALBI) grade is a new index to assess objectively liver function and prognosis in patients with hepatocellular carcinoma (HCC). This study aimed to elucidate the application of ALBI grade in baseline and sorafenib-end in advanced HCC patients who received sorafenib. METHODS: A total of 415 consecutive advanced HCC patients in Child-Pugh A received sorafenib in our hospital. Sorafenib was terminated when radiologic tumor progression or clinical liver function deterioration (LD) occurred in the reassessment bimonthly. Patients who failed with sorafenib monotherapy were retrospectively analyzed. RESULTS: A total of 260 (62.6%) patients were enrolled, including 98 (37.7%) ALBI grade I and 162 (62.3%) grade II in baseline. More patients in ALBI grade II stopped sorafenib because of LD than in grade I (33.3% vs 14.3%, P < 0.001). Those who in baseline ALBI grade I had a superior overall survival than in grade II (8.5 months vs 4.4 months, P = 0.003). Cox regression analysis confirmed that baseline ALBI grade II (P < 0.001) and ALBI grade increase during treatment (P < 0.001) strongly contributed to the mortality of HCC patients who received sorafenib. After sorafenib failure, those with post-sorafenib treatment had a better post-sorafenib survival than those without (9.3 vs 1.6 months, P < 0.001). Logistic regression analysis indicated that sorafenib-end ALBI grade and LD occurrence were the only two predictors of post-sorafenib treatment after sorafenib failure. CONCLUSIONS: In clinical practice, we firstly demonstrated that not only ALBI grade in baseline but also ALBI grade change during treatment could predict the prognosis of advanced HCC patients who received sorafenib.

HATT: a phase IV, single-arm, open-label study of sorafenib in Taiwanese patients with advanced hepatocellular carcinoma.

BACKGROUND: Sorafenib significantly improves survival in patients with advanced hepatocellular carcinoma (HCC). This phase IV study assessed sorafenib efficacy/safety in Taiwanese patients with advanced HCC and Child-Pugh A status. METHODS: All patients received 400 mg sorafenib BID. Safety, efficacy, sorafenib pharmacokinetics, and Child-Pugh progression were evaluated. A hand-foot skin reaction (HFSR) prevention substudy assessed HFSR incidence and grade/severity and time to HFSR in 29 and 34 patients randomized to corticosteroid and noncorticosteroid ointments, respectively, and in 88 nonrandomized patients. RESULTS: The 151 patients included 120 (80%) male patients and 81 (54%) with stage IV disease. Mean sorafenib dose was 626 mg/day, and median treatment duration was 4.2 months. Median overall survival (OS), progression-free survival, and time to progression (TTP) were 8.6, 2.7, and 3.8 months, respectively. Disease control and response rates (partial responses only) were 48 and 6.6%, respectively. Median TTP from Child-Pugh A to B/C was 88 days. Drug-related adverse events (AEs) occurred in 89.4% of patients; none were new or unexpected. The most frequent grade ≥3 drug-related, treatment-emergent AEs were HFSR (13.2%), diarrhea (11.9%), and hypertension (6.6%). Corticosteroid ointment tended to reduce the severity and incidence of all HFSR-associated parameters. Pharmacokinetic exposure was unaltered by Child-Pugh progression. The final pharmacokinetic model predicted 13.1 and 33.8% reductions in sorafenib exposure over 6 and 12 months, respectively. CONCLUSIONS: There was a trend of longer OS and TTP in Taiwanese patients with advanced HCC compared with patients with advanced HCC in the Asia-Pacific trial. Sorafenib exposure did not correlate with liver function. Reduced pharmacokinetic exposure over time was unrelated to reduced or interrupted dosing.

Dichotic multiple-frequency auditory steady-state responses in evaluating the hearing thresholds of occupational noise-exposed workers.

An objective, fast, and reasonably accurate assessment test that allows for easy interpretation of the responses of the hearing thresholds at all frequencies of a conventional audiogram is needed to resolve the medicolegal aspects of an occupational hearing injury. This study evaluated the use of dichotic multiple-frequency auditory steady-state responses (Mf-ASSR) to predict the hearing thresholds in workers exposed to high levels of noise. The study sample included 34 workers with noise-induced hearing impairment. Thresholds of pure-tone audiometry (PTA) and Mf-ASSRs at four frequencies were assessed. The differences and correlations between the thresholds of Mf-ASSRs and PTA were determined. The results showed that, on average, Mf-ASSR curves corresponded well with the thresholds of the PTA contours averaged across subjects. The Mf-ASSRs were 20±8dB, 16±9dB, 12±9dB, and 11±12dB above the thresholds of the PTA for 500Hz, 1,000Hz, 2,000Hz, and 4,000Hz, respectively. The thresholds of the PTA and the Mf-ASSRs were significantly correlated (r=0.77-0.89). We found that the measurement of Mf-ASSRs is easy and potentially time saving, provides a response at all dichotic multiple frequencies of the conventional audiogram, reduces variability in the interpretation of the responses, and correlates well with the behavioral hearing thresholds in subjects with occupational noise-induced hearing impairment. Mf-ASSR can be a valuable aid in the adjustment of compensation cases.

Predicting hearing thresholds and occupational hearing loss with multiple-frequency auditory steady-state responses.

OBJECTIVE: An objective investigation is needed to verify the existence and severity of hearing impairments resulting from work-related, noise-induced hearing loss in arbitration of medicolegal aspects. We investigated the accuracy of multiple-frequency auditory steady-state responses (Mf-ASSRs) between subjects with sensorineural hearing loss (SNHL) with and without occupational noise exposure. DESIGN: Cross-sectional study. SETTING: Tertiary referral medical centre. METHODS: Pure-tone audiometry and Mf-ASSRs were recorded in 88 subjects (34 patients had occupational noise-induced hearing loss [NIHL], 36 patients had SNHL without noise exposure, and 18 volunteers were normal controls). MAIN OUTCOME MEASURES: Inter- and intragroup comparisons were made. A predicting equation was derived using multiple linear regression analysis. RESULTS: ASSRs and pure-tone thresholds (PTTs) showed a strong correlation for all subjects (r = .77 ≈ .94). The relationship is demonstrated by the equationThe differences between the ASSR and PTT were significantly higher for the NIHL group than for the subjects with non-noise-induced SNHL (p < .001). CONCLUSIONS: Mf-ASSR is a promising tool for objectively evaluating hearing thresholds. Predictive value may be lower in subjects with occupational hearing loss. Regardless of carrier frequencies, the severity of hearing loss affects the steady-state response. Moreover, the ASSR may assist in detecting noise-induced injury of the auditory pathway. A multiple linear regression equation to accurately predict thresholds was shown that takes into consideration all effect factors.

Effects of ginger on gastric emptying and motility in healthy humans.

OBJECTIVE: Ginger has been reported to improve upper gastrointestinal symptoms. Little information about the effects of ginger on gastric motor function, exists, however. Our aim was to investigate the effects of ginger on gastric emptying, antral motility, proximal gastric dimensions, and postprandial symptoms. METHODS: Twenty-four healthy volunteers were studied twice in a randomized double-blind manner. After an 8 h fast, the volunteers ingested three ginger capsules (total 1200 mg) or placebo, followed after 1 h by 500 ml low-nutrient soup. Antral area, fundus area and diameter, and the frequency of antral contractions were measured using ultrasound at frequent intervals over 90 min, and the gastric half-emptying time was calculated from the change in antral area. Gastrointestinal sensations and appetite were scored using visual analog questionnaires. Data are expressed in terms of mean+/-standard error. RESULTS: Antral area decreased more rapidly (P<0.001) and the gastric half-emptying time was less after ginger than placebo ingestion (13.1+/-1.1 vs. 26.7+/-3.1 min, P<0.01), whereas the frequency of antral contractions was greater (P<0.005). Fundus dimensions did not differ, and there was no significant difference in any gastrointestinal symptoms. CONCLUSION: Ginger accelerates gastric emptying and stimulates antral contractions in healthy volunteers. These effects could potentially be beneficial in symptomatic patient groups.

One-week versus two-week H2-receptor antagonist in combination with amoxicillin and tinidazole for eradication of Helicobacter pylori infection.

BACKGROUND/AIMS: Eradication regimens combining two antibiotics with a proton pump inhibitor have been studied intensively in Helicobacter pylori (H. pylori) infection; however, only a few reports have focused on the role of H2-receptor antagonists (H2-RAs) in eradication therapy. The mechanism involved in the synergy between antibiotics and H2RAs are still elusive. So we compared the efficacy of two regimens: a 1-week or 2-week course of high-dose H2-RA-based triple therapy in patients with H. pylori infection, and assessed the impact of primary resistance for metronidazole on the treatment outcome. METHODOLOGY: One hundred and twenty patients with peptic ulcers and nonulcer dyspepsia were randomly assigned to a one-week course of famotidine 40mg b.i.d., amoxicillin lg b.i.d. and tinidazole 500 mg b.i.d. (FAT1 group; n = 60) or a 2-week course of famotidine 40 mg b.i.d., amoxicillin lg b.i.d. and tinidazole 500 mg b.i.d. (FAT2 group; n = 60). Upper endoscopy was performed prior to treatment and at least 4 weeks after completion of treatment and discontinuation of the antisecretory therapy. H. pylori status was assessed by biopsy urease test, histology and culture. RESULTS: In the intention-to-treat analysis, eradication of H. pylori was achieved in 38 of 60 patients (63.3%; 95% CI: 51-76%) in the FAT1 group, compared to 48 of 60 patients (80%; 95% CI: 70-92%) in the FAT2 group (NS). In the per protocol analysis, eradication therapy was achieved in 38 of 54 patients (70.4%; 95% CI: 58-82%) in the FAT1 group and 48 of 53 patients (90.6%; 95% CI: 83-98%) in the FAT2 group (p < 0.05). The overall eradication rates for strains susceptible and resistant to metronidazole were 79.7% (95% CI: 71-89%) vs. 60% (95% CI: 44-74%) in the intention-to-treat analysis (p = 0.016) and 84% (95% CI: 76-92%) vs. 71.9% (95% CI: 56-88%) in the per protocol analysis (p = 0.12). Seven patients in the FAT1 group and six patients in the FAT2 group available for follow-up reported adverse events (11.7% and 10% respectively) without necessity of discontinuation of the study medications. Serious adverse events were not observed. CONCLUSIONS: A 2-week course of high-dose H2-RA-based triple therapy is well tolerated and sufficiently effective in eradicating H. pylori infection. Presence of metronidazole resistance has a negative impact on the treatment efficacy.
