Testicular cancer is believed to originate from disruptions of normal androgen-estrogen balance in-utero. α-fetoprotein (AFP) may modify fetal response to estrogens via estrogen interaction. In a cohort study, we investigated the association between circulating maternal pregnancy AFP and testicular cancer risk in offspring. Of the 56,709 live-born males from a pregnancy screening registry in 1980-1995, our study included 50,519 singleton males with available second trimester blood samples from their mothers and complete covariate ascertainment. Testicular cancer diagnoses and covariate data were obtained from nationwide Danish health registries. Cox regression and Kaplan-Meier analyses estimated the prospective risk of testicular cancer (all, seminoma, nonseminoma) by AFP multiples of the median. During follow-up, 163 (0.3%) of the included males developed testicular cancer, of which 89 (54.6%) were nonseminomas. Maternal serum AFP levels greater than/equal to the median were associated with a relative risk of testicular cancer close to unity (RR 1.04, 95% CI 0.76; 1.41) compared to AFP below the median. Associations differed by type of testicular cancer (RRseminoma 0.81, 95% CI 0.51; 1.29, RRnonseminoma 1.31, 95% CI 0.85; 2.02). On balance, our findings do not support that serum AFP in pregnancy can be used as a predictor of testicular cancer in offspring.

Hepatoblastoma (HB) is the most common childhood primary hepatic malignancy. The overall survival rate in patients with HB has reached more than 80% over the past decades. The poor prognostic and high-risk HB have been defined, but the treatment and cure of refractory or relapsed HB is still an arduous task.
The complete records of HB in patients under the age of 18 at the MacKay Memorial Hospital between 1990 and 2019 were examined.
The treatment results for 11 patients with refractory or relapsed HB are presented. The multi-modality treatment records were reviewed and the clinical characteristics associated with poor outcome included multifocal lesions, low α-fetoprotein, great vessel invasion and metastases. Delayed liver tumor surgery was carried out in eight cases. The median duration of follow-up for the 11 patients was 48.6 months (range 1.9 to 316.8 months). The 5-year and 10-year overall survival rate were 62.3% ± 15% (SE) and 49.9% ± 16.4% (SE), respectively. Most treatment-related toxicities were tolerable. The major concern during long term follow-up was irreversible high-frequency hearing loss.
Patients with refractory/relapsed HB are still a thorny issue and more research is needed to improve the outcome.

OBJECTIVE: The aim of this retrospective study was to investigate the efficacy and safety of ramucirumab treatment under real-world conditions and to clarify the role of albumin-bilirubin (ALBI) score in predicting outcomes.
METHODS: Between June 2019 and May 2020, a total of 16 patients with advanced hepatocellular carcinoma (HCC) treated with ramucirumab in Gunma Saiseikai Maebashi Hospital and its affiliated hospitals was included.
RESULTS: The median age was 71 (interquartile range [IQR] 65-74) years old, and 12 patients (75.0%) were male. The modified ALBI (mALBI) grade was 1, 2a, and 2b at baseline in 4 (25.0%), 3 (18.8%), and 9 patients (56.3%), respectively. The Barcelona Clinic Liver Cancer stage was intermediate and advanced stage in 1 (6.3%) and 15 patients (93.8%), respectively. The serum α-fetoprotein at baseline was 4,911 (IQR 2,091-17,377) ng/mL. The disease control rate in patients with mALBI grade1 + 2a was significantly higher than in those with mALBI grade 2b (100 vs. 28.6%, p = 0.028). The patients with mALBI grade 1 + 2a had a significantly better overall survival (OS) and longer progression-free survival (PFS) than those with mALBI grade 2b (median OS 6.7 vs. 3.0 months; p = 0.036, median PFS 7.5 vs. 1.4 months; p = 0.002). The number of cycles of ramucirumab treatment was significantly correlated with the ALBI score (r = -0.452, p = 0.030). The patients with mALBI grade 1 + 2a showed a low incidence of adverse events (AEs) and discontinuation due to AEs.
CONCLUSIONS: Advanced HCC patients with mALBI grade 1 + 2a may be a good indication for ramucirumab treatment.

The purpose of this study was to investigate the expression levels and prognostic roles of α-fetoprotein (AFP), carcinoembryonic antigen (CEA), and Ki67 in tumor tissues of intrahepatic cholangiocarcinoma (ICC) patients.
The study involved ninety-two ICC patients with complete clinicopathological data and follow-up information, who had previously undergone radical surgery. AFP, CEA, CD10, CD34, and Ki67 were detected in tumor tissues using immunohistochemistry. Statistical tests were used to identify independent risk factors and their associations with overall survival (OS) and disease-free survival (DFS).
AFP, CEA and Ki67 were strongly correlated with prognosis. Univariate analysis indicated that higher AFP (P = 0.002), CEA (P < 0.0001), Ki67 (P < 0.0001), CA19-9 (P = 0.039), and CA12-5 (P = 0.002), and larger tumor size (P = 0.001), as well as more advanced tumor node metastasis (TNM) staging (P < 0.0001) were all associated with worse OS. Meanwhile, higher AFP (P = 0.002), CEA (P = 0.001), and Ki67 (P < 0.0001), as well as more advanced TNM staging (P = 0.005) were associated with worse DFS. Multivariate analysis showed that higher AFP (HR = 2.004, 95%CI: 1.146-3.504 P = 0.015), CEA (HR = 2.226, 95%CI: 1.283-3.861 P = 0.004), and Ki67 (HR = 3.785, 95%CI: 2.073-6.909 P < 0.0001), as well as more advanced TNM staging (HR = 2.900, 95%CI: 1.498-5.757 P = 0.002) had associations with worse OS. Furthermore, higher AFP (HR = 2.172, 95%Cl: 1.291-3.654 P = 0.003), CEA (HR = 1.934, 95%Cl: 1.180-3.169 P = 0.009), and Ki67 (HR = 2.203, 95%Cl: 1.291-3.761 P = 0.004) had associations with worse DFS.
High AFP, CEA, and Ki67 are significant prognostic indicators in ICC patients, and can be used to evaluate ICC biological behavior and prognosis.

UNASSIGNED: Dickkopf-1 (DKK-1) is a secreted protein which acts as an inhibitor of Wnt/β-catenin signaling. DKK-1 was found to be a helpful biomarker for many cancers including hepatocellular carcinoma (HCC). HCC is multifactorial in origin and its main etiology in Egypt is attributed to chronic hepatitis C virus (HCV) infection. Objectives: To assess the serum level and diagnostic performance of DKK-1 and α-fetoprotein (AFP) in Egyptian patients with chronic HCV-related liver cirrhosis with and without HCC.
UNASSIGNED: 80 subjects were divided into: a control group (group I, 20 healthy volunteers) and two patient groups: group II (HCV with liver cirrhosis, 30 patients), and group III, (HCV-related liver cirrhosis with HCC, 30 patients). Thorough physical examination, triphasic computed tomography, calculation of Child-Pugh score, laboratory investigations (complete blood picture, liver profile, hepatitis B surface antigen, anti-HCV antibodies, AFP (chemiluminometry) and DKK-1 (ELISA) were performed.
UNASSIGNED: There was a significant decrease in DKK-1 level in HCV patients with liver cirrhosis (group II) and HCV patients with HCC (group III) compared to the control group (group I) (p < 0.001). However, there was a significant increase in DKK-1 level in HCV patients with HCC (group III) compared to HCV patients with liver cirrhosis (group II) (p < 0.033). The ROC curve showed that DKK-1 has less sensitivity but higher specificity in HCV patients with HCC (group III) compared with HCV patients with liver cirrhosis (group II).
UNASSIGNED: The combination of DKK-1 and AFP could further improve the diagnostic accuracy of HCV-related cirrhosis with or without HCC.

Direct acting antivirals (DAA) have recently been developed to treat patients with hepatitis C virus (HCV) infection, and interferon-free DAA treatment has improved the cure rate of patients. However, the occurrence rate of hepatocellular carcinoma (HCC) following HCV eradication remains unknown. Therefore, the present study aimed to identify predictors of HCC occurrence following DAA treatment. Among 1,454 patients infected with HCV, 1,088 patients who achieved sustained virologic response and who had no history of HCC treatment were recruited between September 2014 and November 2018. The incidence of HCC in patients infected with HCV following DAA treatment, and the predictors contributing to HCC occurrence were identified using clinicopathological characteristics and blood test results. During the present study, 26 patients developed HCC. The incidence of HCC was 0.61, 1.88, 2.82 and 3.71% at 6, 12, 18 and 24 months after treatment with DAA, respectively. The results of multivariate analysis identified age [hazard ratio (HR), 1.0729; P=0.0044] and α-fetoprotein (AFP) level after DAA treatment (HR, 1.0486; P=0.0486) as independent factors that may contribute to HCC occurrence following DAA treatment. By using these two factors, a novel scoring system (0-2 points) was established to predict HCC occurrence following HCV eradication by DAA treatment. The incidence of HCC at 2 years was 0.3% in the 0 points group, 6.27% in the 1 point group and 18.37% in the 2 points group. In conclusion, AFP level after DAA treatment and age at DAA administration were identified as independent predictors of HCC occurrence in patients that were treated with DAA. The scoring system that was established in the present study is simple and easy, and using pre-treatment factors may be a convenient tool to predict the risk of HCC occurrence in HCV-free patients following DAA treatment.

BACKGROUND: REACH evaluated ramucirumab in the second-line treatment of patients with advanced hepatocellular carcinoma. In the intent-to-treat population (n = 565), a significant improvement in overall survival (OS) was not observed. In patients with an elevated baseline α-fetoprotein (AFP) level (400 ng/mL or greater), an improvement in OS was demonstrated. An analysis of the Japanese patients in REACH was performed.
METHODS: An analysis was performed with the subset of the intent-to-treat population enrolled in Japan (n = 93).
RESULTS: The median OS was 12.9 months for the ramucirumab arm (n = 45) and 8.0 months for the placebo arm (n = 48) [hazard ratio (HR) 0.621 (95 % confidence interval (CI) 0.391-0.986); P = 0.0416]. The median progression-free survival was 4.1 months for the ramucirumab arm and 1.7 months for the placebo arm [HR 0.449 (95 % CI 0.285-0.706); P = 0.0004]. The objective response rates were 11 % for the ramucirumab arm and 2 % for the placebo arm (P = 0.0817). The grade 3 or higher treatment-emergent adverse events occurring in more than 5 % of patients with a higher incidence for the ramucirumab arm (n = 44) than for the placebo arm (n = 47) were ascites (7% vs 2 %), hypertension (7 % vs 2 %), and cholangitis (7 % vs 0 %). In patients with a baseline AFP level of 400 ng/mL or greater, the median OS was 12.9 months for the ramucirumab arm (n = 20) and 4.3 months for the placebo arm (n = 22) [HR 0.464 (95 % CI 0.232-0.926); P = 0.0263].
CONCLUSIONS: In the Japanese patients in REACH, ramucirumab treatment improved OS, including in patients with a baseline AFP level of 400 ng/mL or greater; improvements in progression-free survival and objective response rate were also demonstrated. The safety profile of ramucirumab was acceptable and well tolerated in Japanese patients. ClinicalTrials.gov identifier NCT01140347.

BACKGROUND: Sorafenib is a standard of care for advanced hepatocellular carcinoma (HCC). An in vitro study showed the synergistic effects of sorafenib and interferon for HCC. To clarify the efficacy, combination therapy with sorafenib and interferon was performed for patients with advanced HCC.
METHODS: Pegylated interferon α-2a was administered every 2 weeks for the initial 4 weeks. Subsequently, it was combined with sorafenib. We evaluated the anti-tumor effect and biomarkers during treatment period.
RESULTS: The subjects were 13 patients with advanced HCC complicated by hepatitis C virus (HCV)-related liver cirrhosis. A partial response, stable disease and progressive disease were noted in 4, 6, and 3 patients, respectively. The response rate, the disease control rate, the mean time to progression and the median survival time (MST) were 30.8 % (4/13), 76.9 % (10/13), 12.2 months, and 17.5 months, respectively. In 8 Child-Pugh class A and 5 Child-Pugh class B patients, the MST was 22.0 and 11.0 months, respectively (p = 0.001). In plasma vascular endothelial growth factor (VEGF), serum alpha-fetoprotein (AFP), AFP-L3, a protein induced by vitamin K absence or antagonist-II (PIVKA II), and hepatocyte growth factor (HGF), there was no pretreatment factor and no biomarker during the combination therapy to predict therapeutic effect in the present study.
CONCLUSIONS: The results of this study suggest that combination therapy with sorafenib and interferon could be effective and safe in advanced HCC patients with HCV-related liver cirrhosis.

BACKGROUND: We assessed the risk factors for the development of hepatocellular carcinoma (HCC) following successful eradication of hepatitis C virus (HCV) with interferon (IFN) therapy in a long-term, large-scale cohort study.
METHODS: We reviewed 1094 consecutive patients with HCV who achieved sustained virological response (SVR) following IFN therapy between January 1995 and September 2013.
RESULTS: During the observation period (median 50 months: range 13-224), 36 (3%) of 1094 patients developed HCC after SVR. The median period from SVR to diagnosis of HCC was 37 months (range 17-141), and the cumulative rates of HCC at 5, 10, and 15 years were 4%, 6%, and 12%, respectively. Multivariate analysis identified old age (≥60 years, HR, 3.1: 95%CI, 1.3-6.6: P = 0.009), male sex (HR, 12.0: 95%CI, 2.8-50.0: P < 0.0001), advanced fibrosis stage (F3/4, HR, 3.2: 95%CI, 1.6-7.2: P < 0.0001), and alpha-fetoprotein ≥10 ng/mL at 1 year after SVR (HR, 7.8: 95%CI, 2.9-16.8: P < 0.0001) as significant and independent risk factors for post-SVR HCC.
CONCLUSIONS: Older age and male sex (host factors), advanced fibrosis stage (pre-IFN treatment factor), and higher alpha-fetoprotein values (post-treatment factor) were significantly associated with HCC development after HCV eradication.
