Radiographic and serologic response in patients with unresectable hepatocellular carcinoma receiving systemic antineoplastic treatments: A trial-level analysis.

BACKGROUND: In a disease like unresectable hepatocellular carcinoma, overall survival is an inadequate outcome measure for evaluating the effectiveness of treatments given the high risk of death from liver failure. There is an unmet need for reliable alternative end points for clinical trials and daily clinical practice. To evaluate treatment response in patients with unresectable or metastatic hepatocellular carcinoma (mHCC), imaging-related end points are often used, whereas serologic end points have been developed for patients with serum alpha-fetoprotein levels >20 ng/mL. The objective of this study was to evaluate clinical trials that report concomitant assessment of radiographic and serologic response in patients with mHCC. METHODS: After a systematic review, studies that evaluated response according to radiographic and serologic criteria were selected. A correlation between progression-free survival (PFS) and overall survival (OS) was performed, and a linear regression of each response-related outcome measure with OS was reported. Finally, the effect of eight baseline variables on OS and response-related measures was evaluated. RESULTS: Twenty-six studies were included, including 16 first-line studies and 10 second-line studies. PFS and response rates demonstrated a significant relationship with OS, whereas disease control rates did not. The responses were correlated with OS, particularly in the first-line setting, after targeted therapy, and whenever assessment was early. Among the baseline variables, only performance status had a prognostic role, whereas hepatitis B virus-related liver disease was associated with higher radiographic response rates. CONCLUSIONS: PFS and radiographic and serologic response rates appear to be reliable intermediate end points in patients with mHCC who are undergoing systemic antineoplastic therapy. However, the serologic response is available earlier.

Diagnostic algorithm for subcentimeter hepatocellular carcinoma using alpha-fetoprotein and imaging features on gadoxetic acid-enhanced MRI.

OBJECTIVE: To investigate the role of serum alpha-fetoprotein (AFP) in diagnosing subcentimeter hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced MRI (EOB-MRI). METHODS: This study retrospectively enrolled treatment-naïve patients with chronic hepatitis B who had a solitary subcentimeter observation on EOB-MRI from January 2017 to March 2023. Final diagnosis was confirmed by pathology for HCC and pathology or follow-up for benign controls. The AFP cutoff value for HCC was determined using Youden's index. Diagnostic criteria were developed according to significant findings in logistic regression analyses based on AFP and imaging features. The diagnostic performance of possible criteria was compared to the diagnostic hallmarks of HCC (arterial-phase hyperintensity and portal-phase hypointensity). RESULTS: A total of 305 patients (mean age, 51.5 ± 10.7 years; 153 men) were divided into derivation and temporal validation cohorts. Four findings, namely AFP >13.7 ng/mL, arterial-phase hyperintensity, portal-phase hypointensity, and transitional-phase hypointensity, were predictors of HCC. A new criterion (at least three of the four findings) showed higher sensitivity than the diagnostic hallmarks (derivation cohort, 71.6% vs. 52.3%, p < 0.001; validation cohort, 75.0% vs. 47.5%, p = 0.003) without decreasing specificity (derivation cohort, 92.5% vs. 92.5%, p > 0.999; validation cohort, 92.0% vs. 92.0%, p > 0.999). Another criterion (all four findings) achieved a slightly higher specificity than the diagnostic hallmark (derivation cohort, 99.1% vs. 92.5%, p = 0.023; validation cohort, 100.0% vs. 92.0%, p = 0.134). Subgroup analysis for hepatobiliary hypointense observations yielded similar results. CONCLUSION: Including AFP in the diagnostic algorithm may improve the diagnostic performance for subcentimeter HCC. CLINICAL RELEVANCE STATEMENT: Combining imaging features on gadoxetic acid-enhanced MRI with alpha-fetoprotein may enhance the diagnostic performance for subcentimeter HCC in treatment-naïve patients with chronic hepatitis B. KEY POINTS: • The traditional diagnostic hallmark of HCC (arterial-phase hyperintensity and portal-phase hypointensity) shows modest diagnostic performance for subcentimeter HCC on EOB-MRI. • Serum alpha-fetoprotein > 13.7 ng/mL, arterial-phase hyperintensity, portal-phase hypointensity, and transitional-phase hypointensity were independent predictors for subcentimeter HCC. • A criterion of at least three of the four above findings achieved a higher sensitivity without decreasing specificity.

Metabolic management after sustained virologic response in elderly patients with hepatitis C virus: A multicenter study.

AIMS: Hepatocellular carcinoma (HCC) develops even in patients with hepatitis C virus (HCV) eradication by direct-acting antiviral agents. Fatty liver and metabolic dysfunction are becoming major etiologies of HCC. We aimed to evaluate the impact of metabolic dysfunction-associated steatotic liver disease (MASLD), a new definition of steatotic liver disease, on the development of HCC after HCV eradication. METHODS: We enrolled 1280 elderly patients with HCV eradication and no history of HCC. We evaluated α-fetoprotein (AFP), Fibrosis-4 index and MASLD after 24 weeks of sustained virological response. Decision tree analysis was used to investigate factors associated with HCC development after HCV eradication. RESULTS: A total of 86 patients (6.7%) developed HCC during the follow-up period (35.8 ± 23.7 months). On multivariate analysis, serum AFP level (HR 1.08, CI 1.04-1.11, P = 0.0008), Fibrosis-4 index (HR 1.17, CI 1.08-1.26, P = 0.0007), and MASLD (HR 3.04, CI 1.40-6.58, P = 0.0125) at 24 weeks of sustained virological response were independent factors associated with HCC development. In decision tree analysis, the initial classifier for HCC development was AFP ≥7 ng/mL. However, in patients with AFP <7 ng/mL, MASLD, rather than Fibrosis-4 index, was the classifier for HCC development. No significant difference was observed in the cumulative incidence of HCC between patients with AFP ≥7 ng/mL and patients with AFP <7 ng/mL and MASLD. CONCLUSION: MASLD at 24 weeks of sustained virological response is a risk factor for HCC development in elderly patients with HCV eradication. Additionally, decision tree analysis revealed that MASLD was associated with HCC development, even in patients with serum AFP levels <7 ng/mL.

Consensus guidelines for the management of pineal region tumours for low- and middle-income countries.

Pineal region tumours are rare and mainly arise at a younger age. They can be categorized into various types: germ cell tumours (GCT), pineal parenchymal tumours (PPT), meningiomas, gliomas, pineoblastoma, pineal parenchymal tumours of intermediate differentiation, papillary tumours of the pineal region, and SMARCB1- mutant desmoplastic myxoid tumour. Within GCT, germinomas are the most prevalent, comprising the majority of tumours in this region, while nongerminomatous GCTs are also present. In rare instances, metastases from other sites may manifest. These tumours often lead to obstructive hydrocephalus and commonly exhibit symptoms related to mass effect, including headache, nausea, vomiting, and impaired gait stability. Different subtypes of pineal region tumours exhibit distinct radiological characteristics, thus imaging remains the primary diagnostic tool. Histologic diagnosis necessitates biopsy, unless in cases of germ cell tumours, particularly germinomas, which can be identified through elevated levels of tumour markers like alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) in both cerebrospinal fluid (CSF) and serum. While benign tumours might be effectively treated with radical resection alone, malignant tumours demand additional chemotherapy and radiotherapy following surgical removal.

[The value of ultrasound-guided puncture biopsy in alpha-fetoprotein negative liver occupying lesions].

Objective: To investigate the accuracy and safety of ultrasound-guided puncture biopsy and enhanced MRI in the diagnosis of alpha-fetoprotein (AFP) negative liver occupying lesions. Methods: Retrospective analysis was conducted on the clinical data of 59 patients with liver occupying lesions who were admitted to the Fifth Medical Center of the PLA General Hospital from February 2015 to November 2017 and received ultrasound-guided coarse needle biopsy with AFP negative. Among them, 35 cases were males and 24 cases were females, the age range was from 25 to 67 years,with an average age of (51±3) years. Serum AFP in all patients were within the normal range. The difference between the pathological results of ultrasound-guided biopsy and the diagnosis of lesions by enhanced MRI was compared, and the diagnostic value of ultrasound-guided biopsy was analyzed. Meanwhile, complications during and after puncture were recorded. SPSS 24.0 software was used for statistical analysis.The measurement data were expressed as x±s and enumeration data were expressed as rate,if the P value was less than 0.05, it indicated that the difference was statistically significant. Results: There were 32 malignant cases and 27 benign cases based on the final pathological diagnosis. The sensitivity and specificity of ultrasound-guided needle biopsy were 100%, in contrast, the enhanced MRI was 96.9% and 81.5%, respectively, with the former significantly higher than the latter. There were no abdominal bleeding,infections and pneumothoraxduring and after the puncture. Conclusion: Ultrasound-guided puncture biopsy and enhanced MRI are both safe for the diagnosis of AFP negative liver occupying lesions,but the former is more sensitive than the latter.When the clinical symptoms of the patient are relatively mild and there is uncertainty in the diagnosis due to the lack of specific enhanced imaging, ultrasound-guided puncture is more conducive to identifying the nature of the lesion.

[Gastric adenocarcinoma with enteroblastic differentiation and elevated serum alpha fetoprotein].

Objective: To study the proportion and clinicopathological characteristics of gastric adenocarcinoma with enteroblastic differentiation (GAED) in gastric cancers showing an elevated serum alpha fetoprotein(AFP). Methods: A total of 724 resected gastric adenocarcinomas were collected from 2008 to 2018 at the 904 Hospital of Joint Service Support Force, and cases with pre-operative serum AFP>10 µg/L were screened. From the cases with elevated serum AFP, GAED cases were further evaluated based on morphology. Then the clincopathological features and immunohistochemical phenotypes of GAED were reviewed. In addition, the amplification of HER2 gene was detected with fluorescence in situ hybridization(FISH). When overall survival (OS) and progression-free survival (PFS) of GAED were analyzed, 289 cases ordinary gastric adenocarcinoma with normal serum AFP were employed as a control. Results: The percentage of GAED was 44% (11/25) in gastric cancers with elevated serum AFP. GAED was histologically tubular or papillary with clear cytoplasm, and some GAED cases showed cystadenoid structure similar to embryo sac (5 cases), homogeneous eosinophilic granules (4 cases) and intragland ulareosinophilic material (6 cases). All 11 GAED cases had lymph node metastasis. Liver metastasis and vascular thrombus were observed in 2 cases and 5 cases respectively. GAED was immunohistochemically positive for CDX2 (11/11), CD10 (8/11) and MUC2(3/11), which were intestinal epithelium differentiation markers. Meanwhile, primitive markers SALL4 (8/11), GPC3 (7/11) and AFP (5/11) were also expressed in GAED, and HER2 gene amplification was found in 3 cases (3/11) of GAED. Lastly, the PFS of GAED were significantly shorter than that of the control group (P=0.02), while OS was not statistically different between these two groups (P=0.99). Conclusions: Patients with GAED usually have a higher rate of elevated serum AFP in gastric adenocarcinoma, and the cancer exhibites features of both intestinal and primitive differentiation. As GAED is highly invasive, the prognosis of GAED may be poor. For GAED, the diagnosis of well-differentiated or moderately-differentiated adenocarcinoma should be avoided, because this diagnosis leads to underestimated malignant potential.

[Diagnostic Value of Abnormal Prothrombin in HBV-related AFP-negative Hepatocellular Carcinoma].

OBJECTIVE: To evaluate the diagnostic value of abnormal prothrombin (DCP) in Alpha-fetoproteins (AFP)-negative (AFP≤20 ng/mL) hepatocellular carcinoma and the relationship between DCP level and Child-Pugh grade, tumor size, TNM stage as well as differentiation. METHODS: The inpatients diagnosed with hepatitis B-related liver disease were collected from June 2016 to December 2017, The diagnostic efficacy of DCP for AFP-negative HCC was analyzed by ROC. Area under the curve ( AUC), the best cut point, sensitivity, specificity, positive predictive value and negative predictive value were calculated. The relationship between DCP levels and the clinical characteristic of HCC was analyzed. RESULTS: A total of 459 hepatitis B markers positive patients were included, including 136 cases of hepatocellular carcinoma, 173 cases of hepatitis B cirrhosis and 150 cases of chronic hepatitis B. DCP in AFP-negative hepatocellular carcinoma group was significantly higher than that in non-HCC group (CHB and LC) ( P<0.05). The AUC of DCP was 0.858, P<0.05. The optimal cut-off point for the diagnosis of hepatocellular carcinoma was 61 mAU/mL. The corresponding sensitivity, specificity, positive predictive value and negative predictive value were 72.8%, 88.2%, 61.1% and 89.7%, respectively. In different size of hepatocellular carcinoma, DCP level of those with diameter>3 cm was significantly higher than those with diameter≤3 cm ( P<0.05). In different TNM stages, DCP level in stage Ⅱ and Ⅲ was significantly higher than that in stage Ⅰ ( P<0.05). There was no significant difference of DCP level among different Child-Pugh grades and differentiation ( P>0.05). CONCLUSION: DCP has diagnostic value for AFP-negative hepatocellular carcinoma, its level may reflects the degree of tumor progression.

Treatment and Outcome of Patients with Stage IS Testicular Cancer: A Retrospective Study from the Spanish Germ Cell Cancer Group.

PURPOSE: Stage IS testicular cancer is defined by the persistence of elevated serum tumor markers, including α-fetoprotein and/or ß-human chorionic gonadotropin, after orchiectomy without radiological evidence of metastatic disease. Current treatment recommendations include cisplatin based chemotherapy up front but the recommendations are based on limited single center series. MATERIALS AND METHODS: We retrospectively analyzed clinical and pathological characteristics, and long-term outcomes in 110 patients uniformly treated with primary chemotherapy between 1994 and 2016. The primary objective was to evaluate long-term disease-free survival. We also explored factors associated with the need for additional treatment. RESULTS: The elevated prechemotherapy tumor markers were α-fetoprotein in 48% of cases, ß-human chorionic gonadotropin in 14%, and α-fetoprotein and ß-human chorionic gonadotropin in 38%. Median α-fetoprotein and ß-human chorionic gonadotropin values were 71 ng/ml and 80 mIU/ml, respectively. The IGCCCG (International Germ Cell Cancer Collaborative Group) prognostic classification was good in 94% of cases. Mixed nonseminomatous germ cell tumor was found in 78% of cases. Of the patients 103 achieved a complete response to chemotherapy. In 6 patients radiological signs of progressive disease developed during chemotherapy, while 8 experienced relapse after an initial complete response. At a median followup of 108 months 108 patients were alive and disease-free. Five and 10-year disease-free survival rates were 87% and 85%, respectively. The predominance of embryonal carcinoma in the primary tumor was the only factor associated with the probability of needing additional therapy. CONCLUSIONS: Stage IS testicular cancer is more commonly associated with elevated α-fetoprotein, an IGCCCG good prognosis and mixed nonseminomatous germ cell tumor. Treatment with cisplatin based chemotherapy leads to cure in most cases. However, a proportion of patients require the integration of additional therapies, including more frequently when embryonal carcinoma is not predominant.

Circulating microRNA-301 as a promising diagnostic biomarker of hepatitis C virus-related hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a serious consequence of persistent hepatitis C virus (HCV) infection and represents one of the most aggressive neoplasms globally. The implication of microRNA-301 (miR-301) in the initiation and progression of different types of cancers has been proved. We aimed to assess circulating microRNA-301 as possible biomarker for the early detection of HCC in patients with chronic HCV infection. miR-301 expression levels were estimated in plasma samples of 42 patients with newly diagnosed HCV-related HCC, 48 chronically HCV infected patients with liver cirrhosis and 40 healthy individuals by reverse transcription-quantitative polymerase chain reaction technique. In comparison with chronically HCV infected patients and healthy controls, miR-301 expression levels were significantly increased in HCC patients (P < 0.001). miR-301 levels distinguished HCC patients from chronic HCV patients, with area under the receiver-operating characteristic curve of 0.89 (95% CI 0.82-0.96), the sensitivity and the specificity were 78.57% and 89.58% respectively. Moreover, miR-301 levels were significantly linked with tumor size (P = 0.014), serum levels of alpha-fetoprotein (AFP) (P = 0.028) and Barcelona Clinic Liver Cancer (BCLC) score (P = 0.003). These results reveal that miR-301 can serve as a promising non-invasive biomarker for diagnosis of HCC in chronically HCV infected patients.

The prognostic utility of baseline alpha-fetoprotein for hepatocellular carcinoma patients.

INTRODUCTION: Alpha-fetoprotein (AFP) has a valuable role in postoperative surveillance for hepatocellular carcinoma (HCC) recurrence. The utility of pretreatment or baseline AFP remains controversial. The present study hypothesized that elevated baseline AFP levels are associated with worse overall survival in HCC patients. METHODS: Adult HCC patients were identified using the National Cancer Database (2004-2013). Patients were stratified according to baseline AFP measurements into the following groups: Negative (<20), Borderline (20-199), Elevated (200-1999), and Highly Elevated (>2000). The primary outcome was overall survival (OS), which was analyzed by log-rank test and graphed using Kaplan-Meier method. Multivariate regression modeling was used to determine hazard ratios (HR) for OS. RESULTS: Of 41 107 patients identified, 15 809 (33.6%) were Negative. Median overall survival was highest in the Negative group, followed by Borderline, Elevated, and Highly Elevated (28.7 vs 18.9 vs 8.8 vs 3.2 months; P < 0.001). On multivariate analysis, overall survival hazard ratios for the Borderline, Elevated, and Highly Elevated groups were 1.18 (P = 0.267), 1.94 (P < 0.001), and 1.77 (P = 0.007), respectively (reference Negative). CONCLUSION: Baseline AFP independently predicted overall survival in HCC patients regardless of treatment plan. A baseline AFP value is a simple and effective method to assist in expected survival for HCC patients.

Pre-treatment alphafeto protein in hepatocellular carcinoma with non-viral aetiology - a prospective study.

BACKGROUND: Alpha-fetoprotein (AFP) is a biomarker for hepatocellular carcinoma (HCC). The significance of pre-treatment AFP (pt-AFP) in non-viral HCC (nvHCC) is not clear. METHODS: Patients with nvHCC, referred to a Hepatobiliary Clinic from September 2011-2015 were screened. HCC was diagnosed using American Association for the Study of Liver Disease guidelines, and TNM staged. nvHCC was diagnosed when HBsAg and anti-HCVAb was negative. Child-Turcotte-Pugh (CTP) and Model for End-stage Liver Disease (MELD) scores were calculated. AFP level was evaluated against patient characteristics, tumour characteristics and survival. RESULTS: Three hundred eighty-nine patients with nvHCC [age 64(12-88) years; 344(88.4%) males] were screened. Median AFP was 25.46 ng/ml (1.16-100,000). 41.2% (n = 160) Of patients had normal AFP level. 22.9% (n = 89) had AFP over 400 ng/ml. Female gender (P < 0.05), vascular invasion (P < 0.001), tumours over 5 cm (P < 0.05), late TNM stage (P < 0.001) and non-surgical candidates had higher AFP levels. Diffuse type (P < 0.001), macro vascular invasion (P < 0.001) and late stage tumours (P < 0.001) had AFP over 400 ng/ml. Having AFP below 400 ng/ml was associated with longer survival (16 vs. 7 months, P < 0.001). CONCLUSION: Pre treatment AFP has a limited value In diagnosing nvHCC, Having a AFP value over 400 ng/ml was associated with aggressive tumour behaviour and poor prognosis.

Vaginal Yolk Sac Tumors: Our Experiences and Results.

OBJECTIVE: Vaginal yolk sac tumors (YSTs) are rare malignant germ cell tumors largely affecting children younger than 3 years. Because of their low incidence, there is no consensus regarding diagnosis and treatment. In this article, we describe the presentation, diagnosis, treatment, and outcomes of 16 patients with vaginal YSTs diagnosed and managed at our center. METHODS: Diagnoses of YST of the vagina were confirmed by 2 experienced pathologists. All patients were treated with bleomycin, etoposide, and cisplatin (PEB) combination chemotherapy alone. Complete remission (CR) was defined by a normal serum α-fetoprotein (AFP) level, no tumor detected on computed tomography, and negative pathology results. Biochemical CR (bCR) was defined by a normal serum AFP level. Long-term follow-up was completed according to our regulations. RESULTS: The median age of patients at diagnosis was 10 months (range, 5-44 months), and all patients presented with abnormal vaginal bleeding and/or vaginal discharge. Serum αAFP is a sensitive tumor marker, and it was markedly elevated in all patients (median 4848 ng/mL; baseline at our hospital is <20 ng/mL). Thirteen patients completed a chemotherapy regimen consisting of PEB alone without surgery. Importantly, all patients achieved CR. Patients received additional cycles of consolidation chemotherapy after bCR and there are no cases of recurrence to date. CONCLUSIONS: We propose a contemporary treatment strategy in line with current practice. First, all suspected cases of vaginal YST should be diagnosed by histopathological examination and serum AFP levels. Second, nonsurgical treatment with PEB chemotherapy should be initiated until patients achieve bCR, followed by an additional 2 cycles of consolidation therapy to optimize results and reduce the risk of remission.

[The prognosis and clinicopathological characteristics of 70 gastric cancer patients with elevated serum AFP].

Objective: This study aimed to review the clinicopathological characteristics and prognosis of advanced gastric cancer patients with elevated serum Alpha-fetoprotein (AFP). Methods: From August 2006 to May 2016, 70patients with advanced gastric cancer were enrolled retrospectively. All these patients had pathologically confirmed gastric adenocarcinoma, had a serum AFP level of more than 20 ng/ml, and received at least first-line treatment. The clinicopathological data and follow-up data were collected for analysis. Results: Liver metastasis was more common in patients with AFP≥1 000 ng/ml, compared with AFP<1 000 ng/ml patients (78.6% vs 57.1%, P=0.064). In patients whose AFP level decreased ≥50% after first-line chemotherapy, the disease control rate and overall survival were both better than those in patients with AFP decreased <50%(96.3% vs 56.7%, P=0.001; 17.2 m vs 8.8 m P=0.007). The overall survival of all these 70 patients ranged from 0.5-50.0 months. 31 patients received chemotherapy only, and 39 patients received combined therapy modality. The overall survival of these two groups were similar(11.0 m and 15.6 m, respectively, P=0.070). Conclusions: Serum AFP-elevated gastric cancer is a special subtype of gastric cancer. It's a heterogeneous cancer with different clinical outcomes. The extent of decrease of serum AFP level during follow-up may be a sensitive prognostic and predictive biomarker. Liver metastasis were more common in these patients, and combined treatment may improve survival.

Alpha-fetoprotein and (18)F-FDG positron emission tomography predict tumor recurrence better than Milan criteria in living donor liver transplantation.

BACKGROUND & AIMS: Given the organ shortage for liver transplantation (LT) and the limitations of the current morphology-based selection criteria, improved criteria are needed to achieve the maximum benefit of LT for hepatocellular carcinoma (HCC). We hypothesized that a combination of biological markers may better predict the prognosis than the Milan criteria. METHODS: HCC patients (n=123) with preoperative data on serum alpha-fetoprotein (AFP) levels and (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG PET) positivity underwent live-donor LT between January 2003 and December 2009. The cut-off values for serum AFP levels (200 ng/ml) and (18)F-FDG PET positivity (1.10) for tumor recurrence were determined by c-statistics using receiver operating characteristic curves. Univariate and multivariate analyses with preoperative variables were performed to find pre-transplant prognostic factors. Disease-free survival rates and overall survival rates were analysed with regard to serum AFP levels and (18)F-FDG PET positivity. RESULTS: The 5-year disease-free survival rates and overall survival rates were 80.3% and 81.6% respectively. (18)F-FDG PET positivity (hazard ratio (HR) 9.766, 95% CI 3.557-26.816; p<0.001) and serum AFP level (HR 6.234, 95% CI 2.643-14.707; p<0.001) were the only significant pre-transplant prognostic factors in the multivariate analysis; tumor number and size were not significant. A combination of criteria showed that the biologically high-risk group (AFP level ⩾200 ng/ml and PET-positive) had an HR of 29.069 (95% CI 8.797-96.053; p<0.001) compared with the double-negative group. Use of the Milan criteria yielded an HR of 1.351 (95% CI 0.500-3.652; p=0.553). CONCLUSIONS: The combination of the serum AFP level and (18)F-FDG PET data predicted better outcomes than those using the Milan criteria, improving objectivity when adult-to-adult living donor LT is contemplated.

Comparison of LUMIPULSE(®) G1200 With Kryptor and Modular E170 for the Measurement of Seven Tumor Markers.

BACKGROUND: Tumor marker measurements are becoming essential for prognosis and follow-up of patients in oncology. In this context, we aimed to compare a new analyzer, Lumipulse(®) G1200 (Fujirebio group, distributed in Europe by the Innogenetics group) with Kryptor(®) (Thermo Fisher Scientific B.R.A.H.M.S, Asnières, France) and Modular(®) Elecsys E170 (Roche Diagnostics, Meylan, France) for the measurement of seven tumor markers: PSA, AFP, CEA, CA 15-3, CA 125, CA 19-9, and Cyfra 21-1. METHODS: A total of 471 serum samples from patients with elevated tumor markers and 100 serum from healthy patients were analyzed with Lumipulse(®) G1200 and either Kryptor(®) (for AFP) or Modular(®) (for the six other markers). RESULTS: The good precision of Lumipulse(®) G1200 assays was confirmed with CVs < 2.5% and < 5.0%, obtained, respectively, for within-run imprecision and intermediate imprecision (except for Cyfra 21-1: CV < 13%). For all markers, Lumipulse results were well correlated with Modular or Kryptor results (r ≥ 0.94). Concordance of results interpretation was > 95% and tumor marker kinetics were all similar. CONCLUSION: We confirmed the analytical performances of Lumipulse(®) tumor marker assays except for the CYFRA 21-1 assay for which performances were poor in this study. We noticed a few discrepancies for the CEA assay. Besides, values obtained for CA 19-9 were higher with Lumipulse leading to a bias (slope = 1.5). But for the four other tumor markers assays (PSA, AFP, CA 125, CA 15-3), the results were directly transferable between Lumipulse and Kryptor or Modular, thus facilitating an eventual substitution of one system by another.

EXPRESS: Study of Role of Melanoma-Associated Antigen D1 (MAGE-D1) in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) ranks as one of the most prevalent malignant tumors globally, being the 5th most common neoplasm and the 3rd leading cause of cancer-related deaths. Despite efforts, current serum biomarkers for HCC surveillance and early diagnosis exhibit low sensitivity and varying specificity, even with different cut-off points and longitudinal assessments. AFP, the most commonly used marker, lacks satisfactory sensitivity and specificity, highlighting an urgent need for more effective markers with higher accuracy for early HCC detection. Exploring novel diagnostic biomarkers holds promise in improving HCC prognosis. There is evidence suggesting that downregulation of MAGE-D1 transcription plays a crucial role in apoptosis and inhibits cancer cell proliferation when expressed ectopically. Moreover, reduced MAGE-D1 expression correlates with improved prognosis in many cancers, underscoring its relevance in cancer development and progression. Therefore, this study aims to evaluate the diagnostic potential of MAGE-D1 in HCC, proposing it as a novel biomarker for early diagnosis and monitoring of tumor progression.

Proposal of an integrated staging system using albumin-bilirubin grade and serum alpha-fetoprotein values for predicting postoperative prognosis of recurrent hepatocellular carcinoma.

BACKGROUND: Because repeat hepatectomy for recurrent hepatocellular carcinoma is a potentially invasive procedure, it is necessary to identify patients who truly benefit from repeat hepatectomy. Albumin-bilirubin grading has been reported to predict survival in patients with hepatocellular carcinoma. However, as prognosis also depends on tumor factors, a staging system that adds tumor factors to albumin-bilirubin grading may lead to a more accurate prognostication in patients with recurrent hepatocellular carcinoma. METHODS: Albumin-bilirubin grading and serum alpha-fetoprotein levels were combined and the albumin-bilirubin-alpha-fetoprotein score was created ([albumin-bilirubin grading = 1; 1 point, 2 or 3; 2 points] + [alpha-fetoprotein<75 ng/mL, 0 points; ≥5, 1 point]). Patients were classified into three groups, and their characteristics and survival were evaluated. The predictive ability of the albumin-bilirubin-alpha-fetoprotein score was compared with that of the Cancer of the Liver Italian Program and the Japan Integrated Stage scores. RESULTS: Albumin-bilirubin-alpha-fetoprotein score significantly stratified postoperative survival (albumin-bilirubin-alpha-fetoprotein score = 1/2/3: 5-year recurrence-free survival [%]: 22.4/20.7/0.0, p < 0.001) and showed the highest predictive value for survival among the integrated systems (albumin-bilirubin-alpha-fetoprotein score/Japan Integrated Stage/Cancer of the Liver Italian Program: 0.785/0.708/0.750). CONCLUSIONS: Albumin-bilirubin-alpha-fetoprotein score is useful for predicting the survival of patients with recurrent hepatocellular carcinoma undergoing repeat hepatectomy.

Clinical Characteristics and Survival of Hepatocellular Carcinoma: Insights from Single-Centre Experience in Saudi Arabia.

Background Hepatocellular carcinoma (HCC) represents the most common primary liver malignancy, with a high fatality rate. Relatively, Saudi Arabia has a high incidence of HCC, which is detected in later stages with a poor prognosis. This study aims to investigate the patterns, outcomes, and mortality predictors of HCC in Saudi Arabia. Method A retrospective study from April 2018 to June 2022 included patients with HCC who were diagnosed and managed at the Najran Oncology Center, Saudi Arabia. Through our cancer registry, the patients' clinical, laboratory, radiological, and survival profiles were extracted and analyzed to assess factors associated with mortality using a univariate analysis. The overall survival was calculated by the Kaplan-Meier method. Results The study involved 52 patients with an average age of 74.6 years, predominantly male (the male-to-female ratio is 2.25:1). Viral infections were the primary cause of liver disease in 40.3% (n=21) of patients. At diagnosis, the Child-Pugh class distribution included 23.1% (n=12) patients in class A, 36.5% (n=19) patients in class B, and 40.4% (n=21) patients in class C. Uninodular tumors with ≤50% liver extension were observed in 65.4% (n=34) of cases, and 30.8% (n=16) had portal vein thrombosis. Elevated alpha-fetoprotein (AFP) levels were noted in 48.1% (n=25) of patients, with 23.1% (n=12) exceeding 400 ng/mL. Curative resection was performed in 32.7% (n=17) of patients. The mean survival time was 23±11.8 months (median of 22.5 months, minimum of six, and maximum of 49 months). Relapse occurred in seven (13.5%) cases, while new metastasis occurred in 20 (38.5%) cases. During the study period, 26 (50.0%) patients died. The main cause of death was disease progression in 15 (28.8%) patients. Univariate analysis showed that AFP>400 ng/mL (OR: 4.68; 95% CI: 1.87-11.66, p=0.001), presence of relapse (OR: 0.16; 95% CI: 0.03-0.78, p=0.023), abdominal ascites (OR: 3.38; 95% CI: 1.25-9.14, p=0.016), advanced the Cancer of the Liver Italian Program (CLIP) score (OR: 0.60; 95% CI: 0.41-0.88, p=0.009) were associated with higher mortality rate and were statistically significant. Conclusion Most cases of HCC in our patients were attributed to viral hepatitis, with the majority having liver cirrhosis. Higher AFP (>400 ng/mL), relapse, abdominal ascites, and a higher cancer CLIP score were associated with poorer outcomes. Targeted screening and health education should be advocated; in addition, social determinants should be proactively addressed.

Effectiveness of Chemotherapy on Long-Term Survival in a Case of Advanced Juvenile Hepatocellular Carcinoma Without Viral Hepatitis Infection.

Hepatocellular carcinoma (HCC) usually occurs in settings of cirrhosis and chronic hepatitis B or C virus (HBV and HCV, respectively) infection; it is extremely rare in patients <40 years of age since viral- or alcohol-induced chronic hepatitis develops over a prolonged period. Juvenile HCC is mostly associated with persistent HBV infection; cases unrelated to HBV or HCV infection (non-B, non-C juvenile HCC) are sporadic and treated in the same way as classical HCC. A woman in her late 30s was diagnosed with HCC in a healthy liver; her imaging findings were typical of HCC with bone metastasis. She was administered a combination of tyrosine kinase inhibitors, immune checkpoint inhibitors, and vascular endothelial growth factor inhibitors. Throughout chemotherapy, the liver reserve was Grade A on the Child-Pugh classification and tumor markers remained under control without marked elevation. Our patient is the first reported long-term survivor of unresectable non-B, non-C juvenile HCC following chemotherapeutic treatment.

Improving Hepatocellular Carcinoma Surveillance Outcomes in Patients with Cirrhosis after Hepatitis C Cure: A Modelling Study.

BACKGROUND & AIMS: Hepatocellular carcinoma (HCC) presents a significant global health challenge, particularly among individuals with liver cirrhosis, with hepatitis C (HCV) a major cause. In people with HCV-related cirrhosis, an increased risk of HCC remains after cure. HCC surveillance with six monthly ultrasounds has been shown to improve survival. However, adherence to biannual screening is currently suboptimal. This study aimed to evaluate the effect of increased HCC surveillance uptake and improved ultrasound sensitivity on mortality among people with HCV-related cirrhosis post HCV cure. METHODS: This study utilized mathematical modelling to assess HCC progression, surveillance, diagnosis, and treatment among individuals with cirrhosis who had successfully been treated for HCV. The deterministic compartmental model incorporated Barcelona Clinic Liver Cancer (BCLC) stages to simulate disease progression and diagnosis probabilities in 100 people with cirrhosis who had successfully been treated for hepatitis C over 10 years. Four interventions were modelled to assess their potential for improving life expectancy: realistic improvements to surveillance adherence, optimistic improvements to surveillance adherence, diagnosis sensitivity enhancements, and improved treatment efficacy Results: Realistic adherence improvements resulted in 9.8 (95% CI 7.9, 11.6) life years gained per cohort of 100 over a 10-year intervention period; 17.2 (13.9, 20.3) life years were achieved in optimistic adherence improvements. Diagnosis sensitivity improvements led to a 7.0 (3.6, 13.8) year gain in life years, and treatment improvements improved life years by 9.0 (7.5, 10.3) years. CONCLUSIONS: Regular HCC ultrasound surveillance remains crucial to reduce mortality among people with cured hepatitis C and cirrhosis. Our study highlights that even minor enhancements to adherence to ultrasound surveillance can significantly boost life expectancy across populations more effectively than strategies that increase surveillance sensitivity or treatment efficacy.
