ABSTRACT

Objective: To explore carnosine dipeptidase 1 (CNDP1) potential value as a diagnostic and prognostic evaluator of hepatocellular carcinoma (HCC). Methods: A gene chip and GO analysis were used to screen the candidate marker molecule CNDP1 for HCC diagnosis. 125 cases of HCC cancer tissues, 85 cases of paracancerous tissues, 125 cases of liver cirrhosis tissues, 32 cases of relatively normal liver tissue at the extreme end of hepatic hemangioma, 66 cases from serum samples of HCC, and 82 cases of non-HCC were collected. Real-time fluorescent quantitative PCR, immunohistochemistry, western blot, and enzyme-linked immunosorbent assay were used to detect the differences in mRNA and protein expression levels of CNDP1 in HCC tissue and serum. Receiver operating characteristic (ROC) curves and Kaplan-Meier survival were used to analyze and evaluate the value of CNDP1 in the diagnosis and prognosis of HCC patients. Results: The expression level of CNDP1 was significantly reduced in HCC cancer tissues. The levels of CNDP1 were significantly lower in the cancer tissues and serum of HCC patients than those in liver cirrhosis patients and normal controls. ROC curve analysis showed that the area under the curve of serum CNDP1 in the diagnosis of HCC patients was 0.753 2 (95% CI 0.676-0.830 5), and the sensitivity and specificity were 78.79% and 62.5%, respectively. The combined detection of serum CNDP1 and serum alpha-fetoprotein (AFP) significantly improved the diagnostic accuracy (AUC = 0.820 6, 95% CI 0.753 5-0.887 8). The diagnostic sensitivity and specificity of serum CNDP1 for AFP-negative HCC patients were 73.68% and 68.75% (AUC = 0.793 1, 95% CI 0.708 8-0.877 4), respectively. In addition, the level of serum CNDP1 distinguished small liver cancer (tumor diameter < 3 cm) (AUC = 0.757 1, 95% CI 0.637 4-0.876 8). Kaplan-Meier survival analysis showed that CNDP1 was associated with a poor prognosis in HCC patients. Conclusion: CNDP1 may be a potential biomarker for the diagnostic and prognostic evaluation of HCC, and it has certain complementarity with serum AFP.

ABSTRACT

Objective: To investigate the clinical value of plasma scaffold protein SEC16A level and related models in the diagnosis of hepatitis B virus-related liver cirrhosis (HBV-LC) and hepatocellular carcinoma (HBV-HCC). Methods: Patients with HBV-LC and HBV-HCC and a healthy control group diagnosed by clinical, laboratory examination, imaging, and liver histopathology at the Third Hospital of Hebei Medical University between June 2017 and October 2021 were selected. Plasma SEC16A level was detected using an enzyme-linked immunosorbent assay (ELISA). Serum alpha-fetoprotein (AFP) was detected using an electrochemiluminescence instrument. SPSS 26.0 and MedCalc 15.0 statistical software were used to analyze the relationship between plasma SEC16A levels and the occurrence and development of liver cirrhosis and liver cancer. A sequential logistic regression model was used to analyze relevant factors. SEC16A was established through a joint diagnostic model. Receiver operating characteristic curve was used to evaluate the clinical efficacy of the model for liver cirrhosis and hepatocellular carcinoma diagnosis. Pearson correlation analysis was used to identify the influencing factors of novel diagnostic biomarkers. Results: A total of 60 cases of healthy controls, 60 cases of HBV-LC, and 52 cases of HBV-HCC were included. The average levels of plasma SEC16A were (7.41 ± 1.66) ng/ml, (10.26 ± 1.86) ng/ml, (12.79 ± 1.49) ng /ml, respectively, with P < 0.001. The sensitivity and specificity of SEC16A in the diagnosis of liver cirrhosis and hepatocellular carcinoma were 69.44% and 71.05%, and 89.36% and 88.89%, respectively. SEC16A, age, and AFP were independent risk factors for the occurrence of HBV-LC and HCC. SAA diagnostic cut-off values, sensitivity, and specificity were 26.21 and 31.46, 77.78% and 81.58%, and 87.23% and 97.22%, respectively. The sensitivity and specificity for HBV-HCC early diagnosis were 80.95% and 97.22%, respectively. Pearson correlation analysis showed that AFP level was positively correlated with alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), and γ-glutamyltransferase (GGT) with P < 0.01, while the serum SEC16A level was only slightly positively correlated with ALT and AST in the liver cirrhosis group (r = 0.268 and 0.260, respectively, P < 0.05). Conclusion: Plasma SEC16A can be used as a diagnostic marker for hepatitis B-related liver cirrhosis and hepatocellular carcinoma. SEC16A, combined with age and the AFP diagnostic model with SAA, can significantly improve the rate of HBV-LC and HBV-HCC early diagnosis. Additionally, its application is helpful for the diagnosis and differential diagnosis of the progression of HBV-related diseases.

ABSTRACT

Objective: To study using isotope-labeled relative and absolute quantitative proteomics methodologies to screen for salivary biological markers as a simple, non-invasive tool for identifying hepatitis B-related HCC at an early stage. Methods: Saliva samples were collected to extract salivary proteins. Isotope-labeled relative and absolute quantitative proteomics were used to analyze the differentially expressed proteins between the hepatocellular carcinoma (HCC) and non-HCC groups. Western blotting, immunohistochemistry, and enzyme-linked immunosorbent assays were used to verify differential proteins and identify markers in liver cancer tissues and saliva. Statistical analysis was used to analyze the diagnostic efficiency of salivary biomarkers. Results: 152 differentially expressed salivary proteins were screened out between the HCC and non-HCC groups. Western blot, immunohistochemistry, and enzyme-linked immunosorbent assays validated that the expressions of α-1-acid glycoprotein 1 (ORM1) and alpha-fetoprotein (AFP) were significantly increased in HCC (P < 0.05). There was a significant correlation between salivary AFP and serum AFP (P < 0.05). HCC was diagnosed when salivary α-1-acid glycoprotein 1 combined with AFP. The area under the receiver operating characteristic curve was 0.8726 (95% confidence interval: 0.8104 ~ 0.9347), the sensitivity was 78.3%, and the specificity was 88%. Conclusion: Salivary AFP and α-1-acid glycoprotein 1 can serve as potential biomarkers for hepatitis B-related hepatocellular carcinoma.

ABSTRACT

Objective: To investigate the clinical value of serum glypican-3 (GPC3) detection in predicting recurrence of primary hepatocellular carcinoma (HCC). Methods: Through univariate and multivariate logistic regression analysis, the patients pathologically diagnosed with HCC in our hospital from March 2019 to January 2021 were enrolled as the experimental group (n=113), and patients with follow-up time longer than 6 months were included in the prognosis group(n=64). At the same time,20 healthy individuals and 20 individuals with benign liver disease from the physical examination center were enrolled by simple random sampling as control group (n=40). The serum GPC3 and alpha-fetoprotein (AFP) levels were respectively detected by ELISA and chemiluminescence. Then, the study explored the influential factors of the recurrence in HCC patients and constructed the HCC-GPC3 recurrence predicting model by logistic regression. Results: In the research, the sensitivity of GPC3 for the diagnosis of HCC was 61.95% (70/113) and AFP was 52.21% (59/113), meanwhile, the specificity of GPC3 could reach 87.50% (35/40) and AFP was 90.00% (36/40),respectively; The serum GPC3 levels of HCC patients with progressive stage, tumor size≥3 cm, vascular cancer thrombosis and portal venous thromboembolism were significantly higher than that of HCC patients with early stage, tumor size<3 cm, vascular cancer thrombosis and portal venous thromboembolism (Z=2.677, 2.848, 2.995, 2.252, P<0.05), independent of different ages, presence or absence of ascites, peritoneal metastasis, cirrhosis, intrahepatic metastasis (Z=-1.535, 1.011, 0.963, 0.394, 1.510, P>0.05), respectively. Univariate analysis showed that there were no statistically significant differences between the recurrence group and the non-recurrence group in terms of different age, tumor size, presence or absence of vascular cancer thrombosis, ascites, peritoneal metastasis, cirrhosis and AFP levels (χ2=2.012, 0.119, 2.363, 1.041, 0.318, 0.360, Z=0.748, P>0.05); The ratio of those with the progressive stage, portal venous thromboembolism and intrahepatic metastasis and GPC3 levels were all higher in the recurrence group than in the non-recurrence group (χ2=4.338, 11.90, 4.338, Z=2.805, P<0.05).Including the above risk factors in the logistic regression model, the logistic regression analysis showed that the stage, the presence of portal venous thromboembolism,intrahepatic metastasis and GPC3 levels were correlated with the prognosis recurrence of HCC patients (Wald χ2 =4.421, 5.681, 4.995, 4.319, P<0.05), and the HCC-GPC3 recurrence model was obtained as: OcScore=-2.858+1.563×[stage]+1.664×[intrahepatic metastasis]+2.942×[ portal venous thromboembolism]+0.776×[GPC3]. According to the receiver operating characteristic curve(ROC), the area under the curve(AUC)of the HCC-GPC3 prognostic model was 0.862, which was better than that of GPC3 alone (AUC=0.704). The cut-off value of model SCORE was 0.699 (the cut-off value of GPC3 was 0.257 mg/L), furthermore, the total sensitivity and specificity of model were 83.3% and 82.4%, which were better than those of GPC3(60.0% and 79.4%).Kaplan-Meier showed that the median PFS was significantly shorter in HCC patients with high GPC3 levels (≥0.257 mg/L) and high values of the model SCORE (≥0.700) (χ2=12.73, 28.16, P<0.05). Conclusion: Besides diagnosing of HCC, GPC3 can may be an independent risk indicator for the recurrence of HCC and can more efficiently predicting the recurrence of HCC patients when combined with the stage, the presence or absence of intrahepatic metastasis and portal venous thromboembolism.

ABSTRACT

This study used m-chloropheniperazine(MCPP) and chronic unforeseeable mild stress(CUMS) to induce the rat models of anxiety and depression, respectively. The behaviors of rats were observed by the open field test(OFT), light-dark exploration test(LDE), tail suspension test(TST), and forced swimming test(FST), and the antidepressant and anxiolytic effects of agarwood essential oil(AEO), agarwood fragrant powder(AFP), and agarwood line incense(ALI) were explored. The enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of 5-hydroxytryptamine(5-HT), glutamic acid(Glu), and γ-aminobutyric acid(GABA_A) in the hippocampal area. The Western blot assay was used to determine the protein expression levels of glutamate receptor 1(GluR1) and vesicular glutamate transporter type 1(VGluT1), exploring the anxiolytic and antidepressant mechanism of agarwood inhalation. The results showed that compared with the anxiety model group, the AEO, AFP, and ALI groups decreased the total distance(P<0.05), decreased the velocity of movements(P<0.05), prolonged the immobile time(P<0.05), and reduced the distance and velocity of the rat model of anxiety in the dark box(P<0.05). Compared with the depression model group, the AEO, AFP, and ALI groups increased the total distance and average velocity(P<0.05), reduced the immobile time(P<0.05), and reduced the forced swimming and tail suspension time(P<0.05). In terms of transmitter regulation, the AEO, AFP, and ALI groups decreased the level of Glu in the rat model of anxiety(P<0.05) and increased the levels of GABA_A and 5-HT(P<0.05), while the AEO, AFP, and ALI groups all increased the level of 5-HT in the rat model of depression(P<0.05) and decreased the levels of GABA_A and Glu(P<0.05). At the same time, the AEO, AFP, and ALI groups all increased the protein expression levels of GluR1 and VGluT1 in the hippocampus of the rat models of anxiety and depression(P<0.05). In conclusion, AEO, AFP, and ALI exert anxiolytic and antidepressant effects, and the mechanism might be related to the regulation of the neurotransmitter and the protein expression of GluR1 and VGluT1 in the hippocampus.

ABSTRACT

BACKGROUND@#Primary lung squamous carcinoma that produces alpha-fetoprotein (AFP) is rare and only four related cases have been reported so far. The specific reasons for elevated serum level of AFP and effective treatment regimens for AFP-producing lung squamous carcinoma are not clear. This paper reports the diagnosis and treatment of AFP-producing lung squamous carcinoma so as to provide some references for similar cases in clinical practice.@*METHODS@#The diagnosis and treatment of an AFP-producing lung squamous carcinoma patient admitted to the Shandong Cancer Hospital on October 23, 2020 was retrospectively analyzed, and literatures were reviewed.@*RESULTS@#A 52-year-old male patient was diagnosed as T4N3M0 stage, IIIc right upper lobe lung squamous cell carcinoma with mediastinal lymph node metastasis and multiple metastases in the lung. The main tumor marker was abnormally increased serum AFP. After the rapid progression of two lines chemotherapy, the patient was given anlotinib combined with carrizumab as third-line treatment. The efficacy evaluation reached to partial response (PR) and stable disease (SD) after 2 and 4 cycles of treatment, respectively. The treatment regimen was replaced with albumin paclitaxel plus carrizumab due to gastrointestinal bleeding after the fifth cycle. The patient's condition was under continuous control.@*CONCLUSIONS@#The AFP-producing lung squamous carcinoma patient had a good response to anlotinib and immunotherapy in the case report, which may provide some guidances for the clinical practice and the research on AFP-producing lung squamous carcinoma.

ABSTRACT

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths and the fifth most common cancer worldwide. Clinically therapeutic options for HCC are very limited, and the overall survival rate of patients is very low. Therefore, early diagnosis and treatment of HCC have important impact on overall survival of patients. At present, alpha-fetoprotein (AFP) is one of the most widely used serological markers for HCC. Many evidences have shown that as a specific onco-protein, AFP has great research value in the occurrence, development, diagnosis and treatment of HCC. Here, we briefly introduce the molecular mechanism of AFP in the regulation of HCC occurrence and development, and its role in tumor escape from immune surveillance. We focus on the application of AFP as an important HCC target or carcino-embryonic antigen (CEA) in HCC clinical diagnosis and treatment.

ABSTRACT

Introducción: La malformación congénita es una alteración estructural de un órgano o parte de este, que sucede como consecuencia de una alteración durante la morfogénesis y que puede corresponder a defectos menores o mayores, únicos, múltiples o asilados. Objetivo: Caracterizar clínica y epidemiológicamente los defectos congénitos del tracto genitourinario. Métodos: Se realizó un estudio observacional retrospectivo en 453 fetos con diagnóstico por ecografía bidimensional de defecto congénito del tracto genitourinario. Para ello se tomó en cuenta la edad materna y gestacional al diagnóstico, antecedentes personales y familiares de interés clínico genético y la conducta terapéutica según criterio médico. Los datos fueron procesados mediante el Programa Microsoft Excel 2010, aplicándoles el método porcentual y los resultados expuestos en forma de tablas. Resultados: El 75,27 por ciento de las anomalías se presentaron en gestantes con edad materna entre 20 y 34 años. El 62,6 por ciento de los defectos fueron diagnosticados en el segundo trimestre del embarazo, con predominio del sexo masculino en los fetos estudiados. La pielocaliectacia (27,3 por ciento) resultó la principal causa de evaluación inicial seguida de la hidronefrosis (26,2 por ciento). Hubo correlación entre el diagnóstico definitivo por ultrasonido y el resultado de la necropsia. Los casos en seguimiento no presentaron ninguna complicación y solo en nueve gestantes se registró interrupción anterior por defectos genitourinarios. Conclusiones: Se constató aumento progresivo del diagnóstico de anomalías congénitas del tracto genitourinario por años de estudio, las pielocaliectacias bilaterales resultaron la principal causa de evaluación inicial(AU)


Introduction: A congenital malformation is a structural alteration of an organ or part of it, which happens as a consequence of an alteration during morphogenesis and may correspond to minor or major, unique, multiple or isolated defects. Objective: To characterize, clinically and epidemiologically, the congenital defects of the genitourinary tract. Methods: A retrospective observational study was carried out in 453 fetuses diagnosed with a congenital defect of the genitourinary tract by using two-dimensional ultrasound. For this, we considered the maternal and gestational ages at diagnosis, personal and family history of clinical genetic interest, and therapeutic behavior according to medical criteria. The data was processed using the program Microsoft Excel 2010, applying the percentage method and the results presented in tables. Results: 75.27 percent of the anomalies occurred in pregnant women with maternal ages between 20 and 34 years. 62.6 percent of the defects were diagnosed at second trimester of pregnancy, with a predominance of the male sex in the studied fetuses. Pyelocaliectasis (27.3 percent) was the main cause of initial evaluation, followed by hydronephrosis (26.2 percent). There was a correlation between the definitive ultrasound diagnosis and the outcome of the autopsy. The follow-up cases did not present any complications and only nine pregnant women presented a previous interruption due to genitourinary defects. Conclusions: A progressive increase in the diagnosis of congenital anomalies of the genitourinary tract was verified for years of study. Bilateral pyelocaliectasis was the main cause of initial evaluation(AU)

ABSTRACT

El hemangioendotelioma hepático del lactante es una patología rara y más aún que su forma de presentación tenga complicaciones graves y el paciente fallezca. Se presenta el caso clínico de una lactante menor de 3 meses de edad que ingresó al Servicio Desconcentrado Hospital Pediátrico Dr. Agustín Zubillaga con diagnóstico de intoxicación herbácea (hierbabuena) e íleo metabólico. La hepatomegalia fue el signo más llamativo en la exploración clínica asociado a valores elevados de alfafetoproteína sérica. Los hallazgos ecosonográficos y tomográficos reportaron múltiples lesiones redondeadas que impresionaron metástasis hepáticas. La paciente fallece a los 23 días de iniciada la enfermedad actual siendo el diagnóstico postmortem hemangioendotelioma cavernoso gigante hepático, Se concluye que en general el diagnóstico de esta enfermedad se puede plantear sin una confirmación histológica, particularmente en lactantes menores, cuando los hallazgos clínicos, analíticos e imagenológicos son muy sugestivos aun cuando hay excepciones como lo presentado en este caso clínico(AU)


Infantile hemangioendothelioma is a rare, usually benign, disease. We present a case of a 3-month-old infant who was admitted in the Servicio Desconcentrado Hospital Pediátrico Dr. Agustín Zubillaga with the diagnosis of herbaceous poisoning (peppermint) and metabolic ileus. Hepatomegaly was the most characteristic sign in clinical examination and was associated with elevated levels of alpha-fetoprotein. Echographic and tomographic findings revealed multiple rounded lesions that impressed liver metastases. The patient died 23 days after admission and the postmortem diagnosis showed giant hepatic cavernous hemangioendothelioma. Diagnosis of hemangioendothelioma usually can be done without histopathological confirmation, especially in infants, when clinical, laboratory and imaging features are very suggestive of this disease, however there are exceptions as the one presented in this case(AU)

ABSTRACT

Abstract Most patients with testicular germ cell tumor present with a painless scrotal mass. We report a 19-year-old patient who presented with neurological complains. Rapid clinical progression to coma was noted during the staging work up. A diagnosis of testicular mixed germ cell tumor with multiorgan metastasis (lymph node, lung, liver and brain) was made. Patients with brain metastasis should receive chemotherapy alone or combined with surgery or radiotherapy. Because the clinical symptoms deteriorated quickly, surgery was used upfront followed by chemotherapy and radiotherapy for the brain tumor. After the first stage of treatment, the clinical symptoms, tumor markers and imaging findings were improved. The residual brain tumor was eliminated by chemotherapy, and only sparse degenerated tumor cells were noted in the brain tissue. Longer follow up is required to assess the impact of our treatment strategy.

ABSTRACT

Gastric cancers that fulfill the Japanese criteria for curative endoscopic resection show a low risk of lymph node (LN) metastasis. Here, we report a case of LN metastasis from early gastric cancer that fulfilled the curative criteria. A 74-year-old Japanese woman was referred to our hospital for treatment of early gastric cancer identified at the site of a hyperplastic polyp that had been diagnosed 10 years prior to presentation. Contrast-enhanced computed tomography did not show any lymphadenopathy and laparoscopy-assisted distal gastrectomy was performed. Histopathological examination revealed a predominantly moderately differentiated adenocarcinoma that measured 15 mm in size and was confined to the mucosa. However, a single metastatic regional LN was observed. A few cancer cells showed positive staining for alpha-fetoprotein. It should be noted that early gastric cancer can be accompanied by LN metastasis even if it fulfills the criteria for curative endoscopic resection.

ABSTRACT

Hepatocellular carcinoma (HCC) is the third most common cause of cancer related death worldwide. Prognosis and treatment options largely depend on tumor stage at diagnosis, with curative treatments only available if detected at an early stage. However, two thirds of patients with HCC are diagnosed at a late stage and not eligible for cure. Therefore several liver professional societies recommend HCC surveillance using abdominal ultrasound with or without alpha fetoprotein in at-risk populations, including patients with cirrhosis and subsets of those with chronic hepatitis B. Available data suggest HCC surveillance can significantly improve early tumor detection, curative treatment eligibility, and overall survival. However, the potential benefits of HCC surveillance must be considered in light a shifting HCC demographic from a viral-mediated cancer to an increasing proportion of patients having non-alcoholic steatohepatitis, which has been shown to limit ultrasound sensitivity and may mitigate observed benefits. Further, benefits of HCC surveillance must be weighed against potential physical, financial and psychological harms. Continued data for both benefits and harms of HCC surveillance in contemporary populations are necessary. In the interim, providers should continue to strive for high quality HCC surveillance in at-risk patients.

ABSTRACT

PURPOSE: To identify the prognostic factors that could influence survival and to compare prognoses of the patients with the number of the risk factors that might assist in the adequate management of hepatocellular carcinoma (HCC) patients with bone metastases that showed a heterogeneous range of survival. MATERIALS AND METHODS: A total of 41 patients, treated with radiotherapy (RT) for bone metastases from HCC from 2014 to 2017, were enrolled retrospectively. Survival was determined by the Kaplan–Meier method from the start of the RT for metastatic bone lesions. Pre-RT clinical features were evaluated and their influences on survival were analyzed. The significant factors were considered to compare survivals according to the number of prognostic factors. RESULTS: Median follow-up was 6.0 months (range, 0.5 to 47.0 months). The median overall survival was 6.5 months, and the 1-year and 2-year survival rates were 35.5% and 13.5%, respectively. Multivariate analysis revealed that the Child-Pugh class A group, alpha-fetoprotein increased more than 30 ng/mL, and HCC size of more than 5 cm were associated with worse overall survival. The median survivals in HCC with none, 1, 2, and 3 of the aforementioned risk factors were 19.5, 9.0, 2.5, and 1.0 months, respectively (p < 0.05). CONCLUSION: Our results show that the overall survivals were significantly different according to the number of the risk factors among HCC patients with bone metastases who showed various lengths of survival.

ABSTRACT

There has been controversy regarding the first-line treatment modality for the patients who have small solitary hepatocellular carcinoma (HCC); radiofrequency ablation (RFA) or percutaneous ethanol injection (PEI), surgical hepatic resection (HR) and liver transplantation (LT). For selection of treatment modality of HCC, it should be considered of hepatic reservoir function as well as the tumor stage. If the liver function is good enough, HR may be the first choice regardless of the tumor size. However, recent studies comparing RFA with resection showed comparable outcome and similar survival rates. RFA, HR and LT provide good outcome for patients who have small HCCs. RFA would be desired in patients who have below 3.0 cm in size and low alpha-fetoprotein (<200 ng/mL). However, in small HCC with high tumor marker, HR should be considered. Better patient selection for the ‘resection first’ approach and early detection of recurrence can achieve better outcomes of the salvage LT strategy. Another benefit of resection first strategy is that it make possible to do enlist of LT for patients before recurrence at high risk of HCC recurrence after resection on the basis of pathologic aggressiveness, microvascular invasion and/or satellites nodule. They should be applied appropriately according to the tumor size, location, tumor markers and underlying liver parenchymal disease.

ABSTRACT

Background: Conventional serum tumor markers (CSTM) are widely used for monitoring patients with cancer. However, their usefulness as a diagnostic tool is controversial in primary or metastatic liver cancer (PMLC). Aim: To evaluate the diagnostic performance of the most commonly requested CSTM in the diagnostic approach of PMLC. Material and Methods: Review of medical records of patients aged over 18 years with a liver biopsy, attended from 2005 to 2017 in a tertiary hospital and a regional cancer center in Colombia. The results of liver biopsies were compared with tumor markers such as carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), CA 19-9, CA 125 and prostate specific antigen (PSA) using a receiver operating characteristic (ROC) curve analysis. Results: We reviewed 2063 medical records and retrieved 118 eligible patients (59 cases and 59 controls, 70% males). Thirty percent had obstructive jaundice. There was heterogeneity in the amount of tumor markers requested according to medical criteria. Only CA 19-9 showed discriminative capacity (> 17.6 U/m), with a cut-off point lower than that reported in the literature and a sensitivity of 69.5%, specificity of 91.6%, a positive likelihood ratio (LR) of 8.32, and a negative LR of 0.33. Conclusions: Except for CA 19-9, tumor markers were not useful for the initial diagnostic approach in patients with suspected primary or metastatic malignant liver tumors.

ABSTRACT

El coriocarcinoma gástrico primario (CGP) es un tumor extremadamente raro, altamente invasivo y de rápida diseminación hematógena. Presentamos el caso de una paciente de 57 años que inicia con cuadro de hematemesis y, progresivamente, se le suman episodios de melena, baja de peso y epigastralgia. Es derivada al Instituto Nacional de Enfermedades Neoplásicas en donde se le realizan gastroscopía y biopsia. Así, el análisis histológico reportó patrón sugestivo para CGP; el cual se confirmó al realizarle a la paciente los estudios por imágenes necesarios y llevar a cabo el análisis inmunohistoquímico para gonadotrofina coriónica humana y alfa feto proteína. Posteriormente, a la paciente se le realiza una gastrectomía radical D2 con preservación esplénica y de cola de páncreas. Lamentablemente, su evolución no fue favorable y fallece por la progresión de la enfermedad.


Primary gastric choriocarcinoma (PGC) is an extremely rare and highly invasive tumor with rapid hematogenous spread. We present the case of a 57-year-old female patient who started with hematemesis and progressive episodes of melena, weight loss and epigastralgia. It is derived from the National Institute of Neoplastic Diseases where gastroscopy and biopsy are performed. Histological analysis reported pattern suggestive of PGC; that was confirmed by immunohistochemical analysis for human chorionic gonadotrophin and fetal alpha protein. Subsequently, the patient underwent a radical D2 gastrectomy with splenic preservation and tail of the pancreas preservation. Unfortunately, her evolution was not favorable and died due to the progression of the disease.

ABSTRACT

PURPOSE: This study was designed to analyze factors related to the success of salvage liver transplantation (SLT) in hepatocellular carcinoma (HCC). While liver resection (LR) is considered the best locoregional therapy in HCC, there is a high recurrence rate. SLT may be the best treatment option when feasible. METHODS: Patients who underwent living donor SLT for recurrent HCC after LR from November 1996 to May 2017 were included. Patient demographic data, clinical and pathologic characteristics, operative data, hospital course, and follow-up data regarding initial LR, locoregional therapy after recurrence and SLT were reviewed. Prognostic factors for recurrence were analyzed using Cox proportional hazard ratio. RESULTS: Eighty-five of 123 SLT patients were included. Patients who had five or more locoregional therapies prior to SLT (hazard ratio [HR], 3.74; 95% confidence interval [CI], 1.45–9.64, P = 0.006), hepatitis B (HR, 9.20; 95% CI, 1.13–74.89; P = 0.04), outside Milan criteria at the time of SLT (HR, 2.66, 95% CI, 1.26–5.63; P = 0.011) and an alpha-fetoprotein level above 1,000 ng/mL at the time of recurrence after initial LR (HR, 6.48; 95% CI, 1.83–22.92; P = 0.004) and at the time of transplantation (HR, 3.43; 95% CI, 1.26–5.63; P = 0.011) were related to significant risk of recurrence. CONCLUSION: Continuing five or more locoregional therapies for recurrent HCC after LR is related to poor recurrence-free survival after SLT.

ABSTRACT

The purpose of this study was to investigate the relationship between serum tumor markers and dietary intakes in healthy adults to address a nutrition guide for cancer prevention. We analyzed tumor-related markers, carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), prostate-specific antigen (PSA), and cancer antigen 125 (CA125) in serum and daily food and nutrient intakes using a 24-hour recall method in 23 healthy men and 32 healthy women. The average age was 50.7 years for men and 48.9 years for women. There were no significant differences in biochemical tumor markers and food intake between the men and women except energy intake. A significantly positive correlation was found between serum AFP, a biochemical marker of liver cancer, and serum glutamic oxaloacetic transaminase (GOT) and/or glutamic pyruvate transaminase (GPT) in both men and women. CEA had a significant and negative correlation with energy intake for men and food intake in women. PSA, a biomarker of prostate cancer, was significantly and positively correlated with the intake of animal iron and cholesterol in men. CA125, a biomarker of gynecologic cancers, was significantly and positively correlated with meat intake in women. As this study revealed the significant relationship between biochemical tumor markers and dietary factors, further studies are needed to elucidate the underlying mechanism of this relationship.

ABSTRACT

BACKGROUND/AIMS: The treatments and outcomes of hepatocellular carcinoma (HCC) with bile duct invasion are not well known. We aimed to confirm the safety of transarterial chemolipiodolization (TACL) and identify prognostic factors for patients with bile duct invasion treated with TACL. METHODS: Fifty patients with central bile duct invasion treated with TACL between 2005 and 2017 were enrolled. Patients were divided into three groups: hyperbilirubinemia (total bilirubin ≥2.5 mg/dL) with pre-TACL biliary drainage, hyperbilirubinemia without biliary drainage, and without hyperbilirubinemia. Tumor response to TACL, survival outcomes, length of hospitalization, adverse events using Common Terminology Criteria for Adverse Events (CTCAE), and factors affecting overall survival were compared. RESULTS: TACL-induced changes of mean CTCAE grades for albumin, alanine aminotransferase, creatinine, prothrombin time, and platelet were not significantly different among patients with or without initial hyperbilirubinemia. Serum bilirubin level was not significantly changed after TACL in all the three groups. Overall survival was not significantly different among the three groups (P=0.097). On multivariate analysis, alpha-fetoprotein < 400 ng/dL (hazard ratio [HR]=0.477, P=0.048) and highest total bilirubin level of < 2.5 mg/dL within one month after TACL (HR=0.335, P=0.004) were significantly associated with longer survival. CONCLUSIONS: TACL was a safe treatment for HCC patients with central bile duct invasion, irrespective of the presence of initial hyperbilirubinemia.
