Atypical Presentation of Sphenoid Sinusitis With Prevertebral Involvement.

Isolated sphenoid sinusitis (ISS) is a rare but potentially serious condition, often leading to severe complications due to delayed diagnosis and treatment. This case report discusses a 75-year-old male with type 2 diabetes mellitus who presented with severe left-sided headache and neck pain. Diagnostic imaging revealed isolated sphenoid sinusitis with prevertebral extension, a rare occurrence that highlights the potential for deep neck space involvement. The patient underwent endoscopic transnasal incision and drainage of the prevertebral abscess with a left sphenoidotomy, resulting in full recovery without recurrence. This case emphasizes the importance of prompt recognition and intervention in ISS, particularly in cases with atypical presentations. The report also discusses the complex anatomy of the sphenoid sinus and its surrounding structures, the broad differential diagnosis of sphenoid sinus opacification, and the necessity for a multidisciplinary approach to management. This case contributes to the limited literature on ISS with prevertebral extension and underscores the critical need for early diagnosis and aggressive treatment to prevent severe complications.

Use of a mobile application to monitor drain sites and surgical wounds after discharge from acute care - A feasibility study in Singapore.

PURPOSE: This study aimed to demonstrate the compliance, feasibility, and acceptability of telehealth monitoring among surgical patients discharged with wounds or drains. METHODOLOGY: This is a cross-sectional feasibility study. Post-surgical breast, plastic, and hepatobiliary patients with wounds and/or surgical drains were recruited using convenience sampling. The control group received conventional care which consisted of daily telephone follow-up. The intervention group used a mobile wound application to take wound and drain images, report drainage amount and symptoms. Compliance was assessed by measuring the percentage of actual to expected patient entries, feasibility was assessed by comparing detection of abnormalities and unexpected hospital visits, and acceptability was assessed by subjective feedback from nurses and patients from the intervention group. RESULTS: 59 patients were recruited, with 30 patients in the control group and 29 patients in the intervention group. 9 specialty nurses were involved in the patients' post-discharge care. The mean compliance rate for the hepatobiliary, breast and plastic patients were 89.9 %, 89.5 % and 75.9 % respectively. 4 patients from the intervention group (13.8 %) and 6 patients from the control group (20.1 %) were flagged as having potential abnormalities. As for unexpected hospital visits, there were 2 (6.9 %) in the intervention group and 1 (3.4 %) in the control group. 25 patients and 9 specialty nurses responded to the feedback survey. 22 patients (88 %) did not face any application issues. 18 patients (72 %) preferred to self-report symptoms via the application rather than to call the nurses and reported feeling safe knowing that they are remotely monitored. Most nurses found the app convenient and timesaving (n = 7, 78 %), with monitoring through pictures as more accurate than phone conversation (n = 8, 89 %). CONCLUSION: The results suggest that use of a mobile application by surgical patients discharged with wounds or drains is feasible and serves as a viable monitoring tool.

Liver resection had better disease-free survival rates compared with radiofrequency ablation in hepatocellular carcinoma: A meta-analysis based on randomized clinical trials.

BACKGROUND: Liver resection (LR) and radiofrequency ablation (RFA) are the most commonly used treatment modalities for early-stage hepatocellular carcinoma (ES-HCC). The comparative efficacy of LR and RFA in ES-HCC remains debated. We conducted a meta-analysis based on randomized trials to compare the outcomes of LR and RFA. METHODS: We searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing RFA and LR interventions for the treatment of ES-HCC. The primary outcomes were overall survival (OS) and disease-free survival (DFS). We used meta-regression to determine the source of heterogeneity and conducted a trial sequential analysis to examine whether the outcome was statistically reliable. RESULTS: Our meta-analysis included nine RCTs with a total of 1,516 HCC patients. Compared with patients receiving RFA, those receiving LR did not have significantly different 2-year OS (HR=1.28, 95% CI: 0.73-2.23) and 5-year OS (HR=1.49, 95% CI: 0.99-2.24). However, patients receiving LR showed a favorable trend in 2-year DFS (HR=1.40, 95% CI: 1.16-1.69) and 5-year DFS (HR=1.37; 95% CI: 1.05-1.77), although these results are not conclusive due to underpowered significance. The heterogeneity was low, and the outcomes were statistically reliable. DISCUSSION: Meta-analysis suggests that while LR shows a favorable trend in DFS compared to RFA for ES-HCC, the present evidence does not thoroughly support recommending LR over RFA. The inconclusive nature of these findings highlights the need for further large-scale RCTs to establish definitive comparative efficacy.

Clinical guidelines for early hepatocellular carcinoma treatment options: a systematic review and bibliometric analysis.

BACKGROUND: Hepatocellular carcinoma (HCC) remains a major cause of cancer-related mortality worldwide, with treatment options including radiofrequency ablation (RFA) and surgical resection. This study evaluates the evolving guidelines for these treatments to identify the current consensus and divergences. METHOD: We conducted a systematic review following PRISMA 2020 guidelines of documents from 2017-2024 by major liver societies. The AGREE-II framework assessed guideline quality. This study is registered with PROSPERO (CRDXXXX). RESULTS: We analyzed 23 guidelines and noted significant shifts in treatment recommendations over recent updates. This analysis reveals an increasing endorsement of RFA for certain patient groups and sustained strong support for surgical resection based on robust evidence levels. All demonstrated high quality, with the 2023 Japan Guidelines receiving the highest AGREE-II score. A significant finding was the low level of stakeholder involvement in the development of guidelines. CONCLUSION: The study highlights the dynamic nature of clinical guidelines for early-stage HCC, underscoring the need for ongoing updates and direct, high-quality comparative studies. The evolving recommendations for RFA, especially its role in managing small, localized tumors, reflect its emerging importance in the treatment paradigm.

External Auditory Canal Squamous Papilloma Presenting with Otitis Externa and Severe Bony Erosion.

We present a case of a 68-year-old lady with an insidious progressive history of otorrhea, otalgia, and reduced hearing for 3 months. She was treated for malignant otitis externa and was treated with systemic antibiotic but showed subtherapeutic response to treatment. She underwent examination under anaesthesia and biopsy with tumour debulking of the right ear via posterior auricular approach and histopathological examination revealed squamous papilloma of the external auditory canal. She recovered well after surgery and was asymptomatic during follow-up.

Validating the Baveno Elastography Criteria of Advanced Liver Fibrosis in Two-Dimensional Shear Wave Elastography: A Prospective Pathology-Based Study.

INTRODUCTION: The Baveno criteria for assessing advanced liver fibrosis were mainly determined by transient elastography (TE), and its pathology-based validation studies in two-dimensional shear wave elastography (2D-SWE) remain limited. We aimed to validate the Baveno criteria through use of 2D-SWE. METHOD: Consecutive patients who underwent liver biopsies for various benign liver diseases were prospectively recruited. Liver stiffness measurement (LSM) was simultaneously evaluated by TE and 2D-SWE. The optimal cutoff value to predict advanced liver fibrosis was determined by the Youden Index, and the diagnostic performance was estimated using area under the receiver operating characteristic (AUROC) analysis. RESULTS: A total of 101 patients were enrolled having a median age of 55.0 (IQR: 46.0-63.5) years, with 53 (52.48%) of them being male. Using <9 and >14 kPa as the optimal dual cutoffs, the AUROC values in TE and 2D-SWE were 0.92 (95% CI: 0.83-0.97) and 0.93 (95% CI: 0.84-0.98), respectively (p = 0.61). The sensitivity and specificity of LSM by TE/2D-SWE achieved rates of 94.44%/94.44% and 86.00%/88.00%, respectively. However, using the Baveno criteria, the AUROC values in TE and 2D-SWE could remain achieving 0.91 (95% CI: 0.82-0.97) and 0.93 (95% CI: 0.84-0.98), respectively (p = 0.36). The sensitivity and specificity in TE/2D-SWE were 88.24%/88.24% and 86.79%/90.57%, respectively. CONCLUSION: This study establishes the compatibility of the Baveno dual cutoff criteria with 2D-SWE, positioning it as an easily used criteria in clinical practice and research.

The Impact of Sequential Therapies after First-Line Systemic Therapies in Unresectable Hepatocellular Carcinoma.

Background: The therapeutic options for hepatocellular carcinoma (HCC) have greatly expanded recently, and current first-line therapies include sorafenib, lenvatinib, and atezolizumab-bevacizumab. The aim of this study was to investigate the therapeutic efficacy of sequential systemic treatments after progressing to the first-line agent in patients with unresectable HCC. Methods: Data were collected from subjects with HCC, BCLC stage B or C, who received first-line sorafenib, lenvatinib, or atezolizumab-bevacizumab from September 2020 to December 2022. The patients who progressed after first-line therapy were evaluated according to individual clinical status in order to decide whether or not to accept sequential therapy. The clinical baseline characteristics and overall survival (OS) of enrolled patients were collected and further analyzed. Results: Among the 127 enrolled patients, percentage of sequential therapy was 67.9%, 21.6%, and 37.5% in those with tumor progression after first-line sorafenib, lenvatinib, or atezolizumab-bevacizumab, respectively. Acceptance of sequential therapy (HR 0.46, p = 0.041) and presentation of ALBI grade I (HR 0.36, p = 0.002) had a significantly positive impact on OS. Pre-treatment ALBI grade had a significant impact on the decision to accept sequential therapy in patients with progressed HCC. Conclusions: The patients who were able to undergo sequential therapy had a better survival outcome compared to those who received only one agent, and the pre-treatment ALBI level might be regarded as a cornerstone tool to assess survival outcomes in patients undergoing treatment for HCC.

A Real-World Experience on a Chinese Population of Patients With Unresectable Hepatocellular Carcinoma Treated With Nivolumab.

Background: For unresectable hepatocellular carcinoma (HCC), nivolumab (anti-programmed death receptor-1 (PD-1)) is used as non-curative interventions. The aim of the study was to focus on the real-world experience of nivolumab applied to patients with HCC. Methods: Unresectable HCC patients receiving nivolumab treatments at Taichung Veterans General Hospital, from June 2018 to May 2020, were recruited. Exclusion criteria were Child-Pugh stage C, poor performance status, a lack of compliance or intolerable to drug treatments. The tumor radiological responses and survival outcomes of enrolled patients were collected and analyzed. Results: Among a total of 57 patients, most of them were classified as Child-Pugh stage A (70.2%) and Barcelona Clinic Liver Cancer (BCLC) stage C (66.7%). Nivolumab was given to 14 (24.6%) as the primary-line, and 43 patients (75.4%) as the secondary-line systemic treatments. The mean therapeutic duration was 6.5 months. Objective response rate (ORR) was 24.6%, and disease control rate (DCR) was 42.1%. The overall median progression-free survival (PFS) was 5.8 months (95% confidence interval (CI): 1.1 - 10.6), and overall survival (OS) was 11.5 months (95% CI: 4.3 - 17.8). Immune-related adverse event (IRAE) was 8.8%. Presence of alpha-fetoprotein (AFP) response (a decline in AFP ≥ 10% from baseline) during therapy predicted the tumor radiological response (to objective response: hazard ratio (HR): 4.89, 95% CI: 1.14 - 21.00; to disease control: HR: 4.71, 95% CI: 1.32 - 16.81). Those with tumor radiological responses showed longer PFS and OS. Conclusions: Decline in AFP during therapy has a predicting role on HCC radiological responses to nivolumab. Achieving radiological responses had better survival outcomes.

Hepatitis C virus antibody seropositivity is associated with albuminuria but not peripheral artery disease in patients with type 2 diabetes.

Hepatitis C virus (HCV) infection is prevalent in patients with type 2 diabetes mellitus (DM). We aimed to investigate whether HCV antibody (Ab) seropositivity is associated with diabetic micro- and macro-vascular diseases. In this hospital-based cross-sectional study, we retrospectively collected data from patients who participated in the diabetes pay-for-performance program and underwent HCV Ab screening in the annual comprehensive assessment between January 2021 and March 2022. We examined the relationships of HCV Ab seropositivity with the spot urinary albumin-to-creatinine ratio (UACR) and ankle-brachial index (ABI) in patients aged ≥ 50 years with type 2 DM. A total of 1758 patients were enrolled, and 85 (4.83%) of the enrolled patients had HCV Ab seropositivity. Multivariable regression analyses revealed that albuminuria showed a dose-dependent association with HCV Ab seropositivity (UACR [30-299 mg/g]: odds ratio [OR] = 1.463, 95% confidence interval [CI] 0.872‒2.456); UACR [≥ 300 mg/g]: OR = 2.300, 95% CI 1.160‒4.562; P for trend = 0.015) when compared with normal albuminuria (UACR < 30 mg/g). However, the proportion of patients with peripheral arterial disease, defined as an ABI ≤ 0.9, was not significantly different between the groups with and without HCV Ab seropositivity (3.5% vs. 3.9%, P = 0.999). In conclusion, severely increased albuminuria, but not the ABI, showed a significant association with HCV Ab seropositivity in patients aged ≥ 50 years with type 2 DM.

Hepatitis Flares or Hepatic Decompensation after Discontinuation of Tenofovir Disoproxil Fumarate and Entecavir in Non-Cirrhotic Hepatitis B e Antigen-Negative Patients.

Hepatic events can occur after discontinuing antiviral therapy. We investigated factors associated with hepatitis flares and hepatic decompensation after discontinuing tenofovir disoproxil fumarate (TDF) and entecavir (ETV). Hepatitis flares within 6 months and hepatic decompensation were compared between non-cirrhotic hepatitis B e antigen-negative patients after discontinuing TDF or ETV by using the Cox proportional hazard model. The cumulative rates of hepatitis flare at 6 months after discontinuing ETV and TDF were 2% and 19%, respectively (p < 0.001). The respective rates of hepatic decompensation at 6 months were 0% and 7% (p = 0.009). Higher alanine aminotransferase (ALT) (AASLD criteria) at the end of treatment (EOT) (HR = 4.93; p = 0.001), an off-therapy dynamic change in HBV DNA (rapid rebound of HBV DNA from the nadir, ≥1 log10 IU/mL per month) (HR = 10.7; p < 0.001), and the discontinuation of TDF (HR = 6.44; p = 0.006) were independently associated with hepatitis flares within 6 months. Older age (HR = 1.06; p < 0.001) and an off-therapy dynamic change in HBV DNA (HR = 3.26; p = 0.028) were independently associated with hepatic decompensation after the discontinuation of antiviral therapy. In summary, we demonstrated several factors associated with hepatitis flares and hepatic decompensation after discontinuing antiviral therapy in non-cirrhotic hepatitis B e antigen-negative patients.

Daily aspirin associated with a reduced risk of hepatocellular carcinoma in patients with non-alcoholic fatty liver disease: a population-based cohort study.

Background: Emerging laboratory and animal studies suggest that aspirin may prevent non-alcoholic fatty liver disease (NAFLD)-related hepatocellular carcinoma (HCC), however clinical evidence remains lacking. Methods: Using Taiwan's National Health Insurance Research Database, we screened 145,212 NAFLD patients from 1997 through 2011. After excluding any confounding conditions, 33,484 patients who continuously received a daily dose of aspirin for 90 days or more (treated group), along with 55,543 patients who had not received antiplatelet therapy (untreated group), were respectively recruited. Inverse probability of treatment weighting using the propensity score was applied to balance the baseline characteristics. Cumulative incidence of, and hazard ratio (HR) for HCC occurrence were analyzed after adjusting competing events. The high-risk patients, who were defined as age ≥ 55 years & elevated serum alanine aminotransferase, were further analyzed. Findings: The 10-year cumulative incidence of HCC in the treated group was significantly lower than that in the untreated group (0.25% [95% CI, 0.19-0.32%] vs. 0.67% [95% CI, 0.54-0.81%]; P < 0.001). Aspirin therapy was significantly associated with a reduced HCC risk (adjusted HR [aHR] 0.48 [95% CI, 0.37-0.63]; P < 0.001). In the high-risk patients, the 10-year cumulative incidence of HCC in the treated group was significantly lower than that in the untreated group (3.59% [95% CI, 2.99-4.19%] vs. 6.54% [95% CI, 5.65-7.42%]; P < 0.001). Aspirin therapy remained associated with a reduced HCC risk (aHR 0.63 [95% CI, 0.53-0.76]; P < 0.001). Subgroup sensitivity analyses verified this significant association in nearly all subgroups. In the time-varying model amongst aspirin users, HCC risk was significantly lower through the use of aspirin for ≥ 3 years (aHR 0.64 [95% CI, 0.44-0.91]; P = 0.013), when compared with short-term use (< 1 year). Interpretation: Daily aspirin therapy is significantly associated with a reduced HCC risk in NAFLD patients.

Severe hepatitis B flares with hepatic decompensation after withdrawal of nucleos(t)ide analogues: A population-based cohort study.

BACKGROUND: Finite nucleos(t)ide analogue (NUC) therapy has been proposed as an alternative treatment strategy for chronic hepatitis B (CHB). AIM: To quantify the incidence of severe hepatitis flares following NUC cessation in everyday clinical practice. METHODS: This population-based cohort study enrolled 10,192 patients (male 71.7%, median age 50.9 years, cirrhosis 10.7%) who had received first-line NUCs for at least 1 year before discontinuing treatment. The primary outcome was severe flare with hepatic decompensation. We used competing risk analyses to assess event incidences and associated risk factors. RESULTS: During a median follow-up of 2.2 years, 132 patients developed severe flares with hepatic decompensation, yielding a 4-year cumulative incidence of 1.8% (95% confidence interval [CI], 1.5%-2.2%). Significant risk factors were cirrhosis (adjusted sub-distributional hazard ratio [aSHR], 2.74; 95% CI, 1.82-4.12), manifestations of portal hypertension (aSHR, 2.46; 95% CI, 1.45-4.18), age (aSHR, 1.21 per 10 years; 95% CI, 1.03-1.42) and male sex (aSHR, 1.58; 95% CI, 1.04-2.38). In patients without cirrhosis or portal hypertension (n = 8863), the 4-year cumulative incidence of severe withdrawal flares stood at 1.3% (95% CI, 1.0%-1.7%). For those patients with available data confirming adherence to the standard stopping rules (n = 1274), the incidence was 1.1% (95% CI, 0.6%-2.0%). CONCLUSIONS: Severe flares with hepatic decompensation were observed in 1%-2% of patients with CHB after stopping NUC therapy in daily practice. Risk factors included older age, cirrhosis, portal hypertension and male sex. Our findings argue against NUC cessation as part of routine clinical care.

Risk Stratification for Hepatitis B Virus Reactivation in Kidney Transplant Recipients With Resolved HBV Infection.

The prophylaxis strategy for hepatitis B virus (HBV) reactivation in kidney transplant recipients (KTRs) with resolved HBV infection remains unclear. In this hospital-based retrospective cohort study, consecutive KTRs with resolved HBV infection were screened from the years 2000 through 2020. After excluding confounding conditions, 212 and 45 patients were respectively recruited into Anti-HBs positive and Anti-HBs negative groups. Cumulative incidences of, and subdistribution hazard ratios (SHRs) for HBV reactivation were analyzed after adjusting the competing risk. During a median 8.3 (mean 8.4 ± 4.9) years of follow-up, the 10-year cumulative incidence of HBV reactivation was significantly higher in Anti-HBs negative group when compared to that in Anti-HBs positive group (15.2%, 95% CI: 3.6-26.7 vs. 1.3%, 95% CI: 0.0-3.0; p < 0.001). In multivariable regression analysis, absence of anti-HBs (SHR 14.2, 95% CI: 3.09-65.2; p < 0.001) and use of high-dose steroids, i.e., steroid dose ≥20 mg/day of prednisolone equivalent over 4 weeks (SHR 8.96, 95% CI: 1.05-76.2; p = 0.045) were independent risk factors related to HBV reactivation. Accordingly, the 10-year cumulative incidence of HBV reactivation occurring in patients with two, one and zero risk factors was 42.7% (95% CI: 0.0-87.1), 7.9% (95% CI: 1.2-14.7) and 0%, respectively (p < 0.001). In conclusion, the strategy of HBV antiviral prophylaxis may be defined according to the risk stratification.

A Rare Case of Cerebrospinal Fluid Rhinorrhea from Canal of Stenberg.

Background: A spontaneous cerebrospinal leak from Sternberg's canal with meningoencephalocele is a very rare clinical entity. Endoscopic repair of the defect is challenging and crucial in identifying the defect. The aim of this case report is to highlight the presence and management with endoscopic surgery in repairing Sternberg canal. Case: 40-year-old woman presents with spontaneous CSF rhinorrhea with no predisposing factors. CT imaging and MRI showed osteodural defect in the lateral recess of sphenoid with meningoencephalocoele lateral to the foramen rotundum. Endoscopic transethmoidal - transphenoidal - transpterygoid approach was used to repair the defect, and patient is well post-operative with least complication from the intervention surgery. Conclusion: Endoscopic approach proved to be the best and safest method in localizing the defect and closure of the leak. Angled scopes and image guided system were used to identify the precise location of the leak.

Utility of combining PIVKA-II and AFP in the surveillance and monitoring of hepatocellular carcinoma in the Asia-Pacific region.

Even though the combined use of ultrasound (US) and alpha-fetoprotein (AFP) is recommended for the surveillance of hepatocellular carcinoma (HCC), the utilization of AFP has its challenges, including accuracy dependent on its cut-off levels, degree of liver necroinflammation, and etiology of liver disease. Though various studies have demonstrated the utility of protein induced by vitamin K absence II (PIVKA-II) in surveillance, treatment monitoring, and predicting recurrence, it is still not recommended as a routine biomarker test. A panel of 17 experts from Asia-Pacific, gathered to discuss and reach a consensus on the clinical usefulness and value of PIVKA-II for the surveillance and treatment monitoring of HCC, based on six predetermined statements. The experts agreed that PIVKA-II was valuable in the detection of HCC in AFP-negative patients, and could potentially benefit detection of early HCC in combination with AFP. PIVKA-II is clinically useful for monitoring curative and intra-arterial locoregional treatments, outcomes, and recurrence, and could potentially predict microvascular invasion risk and facilitate patient selection for liver transplant. However, combining PIVKA-II with US and AFP for HCC surveillance, including small HCC, still requires more evidence, whilst its role in detecting AFP-negative HCC will potentially increase as more patients are treated for hepatitis-related HCC. PIVKA-II in combination with AFP and US has a clinical role in the Asia-Pacific region for surveillance. However, implementation of PIVKA-II in the region will have some challenges, such as requiring standardization of cut-off values, its cost-effectiveness and improving awareness among healthcare providers.

Serious adverse events after cessation of nucleos(t)ide analogues in individuals with chronic hepatitis B: A systematic review and meta-analysis.

Background & Aims: The risk of serious clinical outcomes following cessation of nucleos(t)ide analogues (NUCs) in individuals with chronic hepatitis B remains poorly characterized. This systematic review and meta-analysis aimed to evaluate current literature on this issue. Methods: We searched PubMed, Embase, and Web of Science for NUC stop studies that noted clinical outcomes published between January 1, 2006 and August 18, 2022. We performed meta-research analyses to examine the relationships of reported outcomes with study designs and characteristics and also pooled studies with non-overlapping populations to provide risk estimates for the proportions of (1) severe hepatitis flares or hepatic decompensation or (2) hepatitis flare-related death or liver transplantation. Results: The meta-research analysis included 50 studies of highly heterogeneous designs and characteristics. We found that reporting of safety outcomes varied widely according to outcome definition, follow-up duration, and sample size. Only ten studies prespecified safety events as the study outcome, and only four had an outcome definition to include hepatic insufficiency, a follow-up duration >12 months, and a sample size >100 patients. We further pooled 15 studies with 4,525 individuals and estimated that severe hepatitis flares or decompensation would occur in 1.21% (95% CI 0.70-2.08%), with significant heterogeneity (I 2 = 54%, p <0.01), while hepatitis flare-related death or liver transplantation would occur in 0.37% (95% CI 0.20-0.67%), without significant heterogeneity (I 2 = 0.00%, p = 1.00). Conclusions: Current literature on the risk of serious clinical outcomes following NUC cessation is very limited and highly heterogeneous. Pooled analyses of available data found approximately 1% of patients who stopped NUCs developed severe flares or hepatic decompensation. Impact and implications: Current literature regarding the safety concerns surrounding NUC cessation for individuals with chronic hepatitis B is limited and heterogeneous in designs and characteristics, and thus should be interpreted with great caution. Based on currently available data, the proportion of patients that develop severe hepatitis flares or hepatic decompensation was estimated at 1.21% and that of flare-related death or liver transplantation at 0.37%. Our findings are important for individuals receiving nucleos(t)ide analogues for hepatitis B virus infection because we not only pooled currently available data to estimate the risk of serious clinical adverse events following treatment cessation but also uncovered critical limitations of existing literature regarding the safety of finite therapy.

Direct-Acting Antiviral Therapy for Hepatitis C Virus in Patients with BCLC Stage B/C Hepatocellular Carcinoma.

BACKGROUND: The benefits of hepatitis C virus (HCV)eradication for hepatocellular carcinoma (HCC) patients in Barcelona Clinic Liver Cancer (BCLC) stage B/C remain uncertain. METHODS: In this hospital-based cohort study, all HCV-infected patients with BCLC stage B/C HCC during the period January 2017 to March 2021 were retrospectively screened, with 97 patients who had completed direct-acting antiviral (DAA) therapy being enrolled for final analysis. RESULTS: In total, the sustained virological response (SVR) rate was 90.7%. In logistic regression analysis, progressive disease (PD) to prior tumor treatments was significantly associated with SVR failure (odds ratio 5.59, 95% CI 1.30-24.06, p = 0.021). Furthermore, the overall survival (OS) rate was significantly higher in the SVR group than that in the non-SVR group (1-year OS: 87.5% vs. 57.1%, p = 0.001). SVR was found to be an independent factor related to OS (hazard ratio 8.42, 95% CI 2.93-24.19, p = 0.001). However, even upon achieving SVR, the OS rates in BCLC stage C or Child-Pugh stage B patients remained poor. CONCLUSIONS: In BCLC stage B/C HCC, DAA could achieve a high SVR rate except in those patients with PD to prior HCC treatments. SVR was related to improvements in OS; therefore, DAA therapy should be encouraged for patients diagnosed without a short life expectancy.

The radiological prognostic factors of transcatheter arterial chemoembolization to hepatocellular carcinoma.

Transcatheter arterial chemoembolization (TACE) is the recommended treatment modality for intermediate stage hepatocellular carcinoma (HCC). The aim of this study was to determine the HCC radiological characteristics associated with prognosis of patients with intermediate stage HCC receiving TACE. Patients with HCC BCLC stage B from January 2005 to December 2009 were collected. According to mRECIST criteria, patients with complete response and partial response were assigned to the objective response (OR) group, while those with stable disease and progressive disease were assigned to the nonobjective response (non-OR) group. Among a total of 128 enrolled patients, there were 66 (51.6%) and 62 (48.4%) patients in the OR group and non-OR group, respectively. The clinical parameters in the two groups were similar, although HCC size was smaller in the OR group. Logistic analysis found combined radiological characteristics including complete lipiodol retention, tumor feeding artery blockage, and no residual tumor blush were significant correlated with achievement of OR (odds ratio 2.46, 95% CI 1.08-5.61, P = .032). However, no radiological characteristics had significant strength to predict overall survival. Patients with OR after TACE had significantly longer survival time than those with non-OR. Combined characteristics of complete lipiodol retention, tumor feeding artery blockage, and no residual tumor blush had a positive impact on OR in TACE. In patients receiving TACE, those who achieved OR had a better overall survival.

The Combining of Tyrosine Kinase Inhibitors and Immune Checkpoint Inhibitors as First-Line Treatment for Advanced Stage Hepatocellular Carcinoma.

AIM: Hepatocellular carcinoma (HCC) is one of the most common cancers. Tyrosine kinase inhibitors (TKIs), including sorafenib (SOR) and lenvatinib (LEN), as well as immune checkpoint inhibitors (ICIs), including nivolumab (NIVO) and pembrolizumab (PEMBRO), have been approved for the treatment of advanced HCC. The aim of the study is to determine whether advanced-stage HCC patients should receive a combination of TKI and ICI as first-line therapy. METHODS: Data for subjects with BCLC stage C HCC, who were receiving combining TKI and ICI as first-line therapy at Taichung Veterans General Hospital from April 2019 to July 2021, were evaluated. The general and therapeutic outcome data were collected and analyzed. RESULTS: A total of 33 patients were enrolled (8 SOR/NIVO, 4 SOR/PEMBRO, 11 LEN/NIVO, and 10 LEN/PEMBRO). All cases belonged to Child-Pugh class A. The objective response rate was 48.5%, and disease control rate was 72.7%. The average progression-free survival (PFS) and overall survival (OS) of all patients was 9.2 and 17.0 months, respectively. The use of PEMBRO, when compared with NIVO, had a significantly positive impact towards achieving an objective response, defined as either complete response or partial response (OR 5.54, p = 0.045). PFS and OS between the different TKIs or ICIs had no differences. The most adverse event was fatigue (36.4%), and most cases were mild and manageable. CONCLUSION: Combining TKI and ICI provides an acceptable antitumor efficacy in first-line therapy for advanced-stage HCC patients. The survival outcomes between different TKIs or ICIs display no differences.

Accuracy of simultaneous measurement of serum biomarkers: Carbohydrate antigen 19-9, pancreatic elastase-1, amylase, and lipase for diagnosing pancreatic ductal adenocarcinoma.

BACKGROUND: Pancreatic cancer is difficult to diagnose early since tumor markers have low sensitivity and specificity. We simultaneously measured serum carbohydrate antigen (CA) 19-9, pancreatic elastase-1, lipase, and amylase, and evaluated the accuracy of a single marker or a combination of two, three, or four markers in the diagnosis of pancreatic ductal adenocarcinoma (PDAC). METHODS: Seventy-six patients with PDAC were included, and 75 patients with non-PDAC diseases were enrolled as the control group. Blood specimens were collected and analyzed for pancreatic elatase-1, CA19-9, amylase and lipase. Sensitivity, specificity, and accuracy for each individual marker and in combination were determined. RESULTS: In PDAC subjects, abnormal CA19-9 was seen most frequently at 80.3%, followed by pancreatic elastase-1 at 57.9%, lipase at 53.9%, and amylase at 51.3%. In non-PDAC subjects, the percentage of abnormal serum pancreatic elastase-1, CA19-9, lipase, and amylase were 50.7%, 41.3%, 40.0%, and 28.0%, respectively. The accuracy rate of amylase and CA19-9 results combined was 64.9% and was higher than the combination of other markers in the intersection set. In the union set, the group of amylase and CA19-9 combined and the group of lipase and CA19-9 combined had the highest accuracy at 66.2%. In the intersection and union set, the area under the curve of CA19-9 was the highest at 0.695. CONCLUSION: CA19-9 as a single marker is the most accurate in the clinical diagnosis of PDAC. Combination of lipase, amylase, or pancreatic elastase-1 results does not significantly increase the accuracy of PDAC diagnosis.
