Abstract
BACKGROUND/AIM: Acute lymphoblastic leukemia (ALL) is frequent among children. Few studies have researched the relationship between maternally expressed gene 3 (MEG3) and cancer risk. We hypothesized long non-coding RNA MEG3 polymorphisms might influence the risk of childhood ALL. MATERIALS AND METHODS In a total of 266 patients with childhood ALL and 266 healthy controls, genotypes of MEG3 rs7158663, rs3087918, rs11160608 and rs4081134 single nucleotide polymorphisms were investigated for their associations with childhood ALL. RESULTS MEG3 rs7158663 AG and AA genotypes were significantly associated with ALL [odds ratio=1.61 (95% confidence interval=1.12-2.31) and 2.21 (1.16-4.22), respectively]. The A allele also exhibited a statistical association with higher risk of ALL (p=0.0015). There was no positive association as for rs3087918, rs11160608 or rs4081134. Interestingly, a significant interaction between MEG3 rs7158663 and age (≥3.5 years) and gender (male) was found. CONCLUSION MEG3 rs7158663 AG/AA genotypes were associated with higher susceptibility to childhood ALL. These novel findings should be validated in larger populations and different ethnicities.

Abstract
BACKGROUND Experimental and epidemiologic evidence supports the role of circulating insulin-like growth factor-1 (IGF-1) levels with the risk of prostate cancer. Most circulating IGF-1 is bound to specific binding proteins, and only about 5% circulates in a free form. We explored the relation of free IGF-1 and other components of the IGF system with lethal prostate cancer. METHODS Using prospectively collected samples, we undertook a nested case-only analysis among 434 men with lethal prostate cancer and 524 men with indolent, nonlethal prostate cancer in the Physicians' Health Study and the Health Professionals Follow-up Study. Prediagnostic plasma samples were assayed for free IGF-1 and total IGF-1, acid labile subunit, pregnancy-associated plasma protein A (PAPP-A), and intact and total IGF binding protein 4. We estimated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the associations between IGF-1-related biomarkers and lethal prostate cancer using unconditional logistic regression models adjusted for age, height, and body mass index. RESULTS Men in the highest quartile of PAPP-A levels had 42% higher odds of lethal prostate cancer (pooled adjusted OR = 1.42, 95% CI = 1.04 to 1.92) compared with men in the lowest 3 quartiles. There were no statistically significant differences in the other plasma analytes. The positive association between PAPP-A and lethal prostate cancer was present among men with intact PTEN but not among those with tumor PTEN loss (2-sided P interaction = .001). CONCLUSIONS Our study provides suggestive evidence that among men who later develop prostate cancer, higher plasma PAPP-A levels measured prior to diagnosis are associated with increased risk of lethal compared with indolent disease.

Mo, T, Liu, X, Luo, Y, Zhong, L, Zhang, Z, Li, T, Gan, L, Liu, X, Li, L, Wang, H, et al
Cancer science. 2022;(1):7-16
Abstract
An aptamer is a short oligonucleotide chain that can specifically recognize targeting analytes. Due to its high specificity, low cost, and good biocompatibility, aptamers as the targeting elements of biosensors have been applied widely in non-invasive tumor imaging and treatment in situ to replace traditional methods. In this review, we will summarize recent advances in using aptamer-based biosensors in tumor diagnosis. After a brief introduction of the advantage of aptamers compared with enzyme sensors and immune sensors, the different sensing designs and mechanisms based on 3 signal transduction modes will be reviewed to cover different kinds of analytical methods, including: electrochemistry analysis, colorimetry analysis, and fluorescence analysis. Finally, the prospective advantages of aptamer-based biosensors in tumor theranostics and post-treatment monitoring are also evaluated in this review.

Disease markers. 2022;:8567642
Abstract
BACKGROUND Recent studies have shown that nicotinamide adenosine dinucleotide phosphate oxidase 4 (NOX4) is related to cancer development, proliferation, invasion, epithelial-to-mesenchymal transition, and metastasis. The prognostic value of NOX4 expression although has been reported in various cancers, it remains unclear as several studies have reported conflicting results. Therefore, the purpose of this study was to systematically investigate the prognostic value of NOX4 expression in cancer patients. METHOD Appropriate studies were collected by searching the PubMed, EMBASE, and Cochrane library databases, and the prognostic value of NOX4 expression in cancer patients was assessed through a meta-analysis. RESULTS Nine eligible studies involving 2675 cancer patients were included in this meta-analysis. We found that NOX4 expression is related to prognosis in cancer patients. In particular, high expression of NOX4 was significantly associated with overall survival in patients with gastrointestinal cancer (hazard ratio [HR]: 1.83, 95% confidence interval [CI]: 1.39-2.42, p < 0.001). CONCLUSION NOX4 expression is significantly correlated with overall survival in patients with gastrointestinal cancer, indicating that it could be a potential prognostic marker.

Abstract
PURPOSE Interventional hepatic arterial infusion chemotherapy of infusional fluorouracil, leucovorin, and oxaliplatin (HAIC-FO) displayed an encouraging safety profile and antitumor activity in a previous phase II trial and a propensity-score-matching study involving patients with locally advanced hepatocellular carcinoma (HCC). METHODS In this open-label, phase III trial, patients with advanced HCC, previously untreated with systemic therapy, were randomly assigned in a 1:1 ratio to receive HAIC-FO or sorafenib. The primary end point was overall survival (OS) in the intention-to-treat population. An exploratory model for predicting the efficacy of HAIC-FO on the basis of genomic sequencing was developed. RESULTS Between May 2017 and May 2020, 262 patients were randomly assigned. The median tumor size was 11.2 cm (interquartile range, 8.5-13.7 cm). Macrovascular invasion was present in 65.6%, and the percentage of patients with > 50% tumor volume involvement of the liver and/or Vp-4 portal vein tumor thrombosis was 49.2%. At data cutoff (October 31, 2020), median OS was 13.9 months for HAIC-FO and 8.2 for sorafenib (hazard ratio [HR] 0.408; 95% CI, 0.301 to 0.552; P < .001). Tumor downstaging occurred in 16 (12.3% of 130) patients receiving HAIC-FO, including 15 receiving curative surgery or ablation, and finally achieving a median OS of 20.8 months, with a 1-year OS rate of 93.8%. In high-risk subpopulations, OS was significantly longer with HAIC-FO than with sorafenib (10.8 months v 5.7 months; HR 0.343; 95% CI, 0.219 to 0.538; P < .001). A newly developed 15-mutant-gene prediction model identified 83% of patients with response to HAIC-FO. HAIC-FO responders had longer OS than HAIC-FO nonresponders (19.3 months v 10.6 months; HR 0.323; 95% CI, 0.186 to 0.560; P = .002). CONCLUSION HAIC-FO achieved better survival outcomes than sorafenib in advanced HCC, even in association with a high intrahepatic disease burden.

Abstract
The identification of biomolecules associated with papillary thyroid cancer (PTC) has upmost importance for the elucidation of the disease mechanism and the development of effective diagnostic and treatment strategies. Despite particular findings in this regard, a holistic analysis encompassing molecular data from different biological levels has been lacking. In the present study, a meta-analysis of four transcriptome datasets was performed to identify gene expression signatures in PTC, and reporter molecules were determined by mapping gene expression data onto three major cellular networks, i.e., transcriptional regulatory, protein-protein interaction, and metabolic networks. We identified 282 common genes that were differentially expressed in all PTC datasets. In addition, six proteins (FYN, JUN, LYN, PML, SIN3A, and RARA), two Erb-B2 receptors (ERBB2 and ERBB4), two cyclin-dependent receptors (CDK1 and CDK2), and three histone deacetylase receptors (HDAC1, HDAC2, and HDAC3) came into prominence as proteomic signatures in addition to several metabolites including lactaldehyde and proline at the metabolome level. Significant associations with calcium and MAPK signaling pathways and transcriptional and post-transcriptional activities of 12 TFs and 110 miRNAs were also observed at the regulatory level. Among them, six miRNAs (miR-30b-3p, miR-15b-5p, let-7a-5p, miR-130b-3p, miR-424-5p, and miR-193b-3p) were associated with PTC for the first time in the literature, and the expression levels of miR-30b-3p, miR-15b-5p, and let-7a-5p were found to be predictive of disease prognosis. Drug repositioning and molecular docking simulations revealed that 5 drugs (prochlorperazine, meclizine, rottlerin, cephaeline, and tretinoin) may be useful in the treatment of PTC. Consequently, we report here biomolecule candidates that may be considered as prognostic biomarkers or potential therapeutic targets for further experimental and clinical trials for PTC.

Abstract
Medullary thyroid cancer (MTC) is the third frequent subtype of thyroid cancer-driving from thyroid C-cells. The first-line strategy to treat MTC is surgery, but tumor recurrence and patients' mortality rate have still been demonstrated in approximately 4-10% of MTC cases. Therefore, to treat and prevent the progressive form of the disease, the early diagnosis of MTC is assumed to play a critical role. In this regard, recently, circulating biomarkers have drawn researchers' attention for their nonaggressive manners in the sample collection. In this systematic review, we aimed to focus on circulating biomarkers and their applications in MTC diagnosis, prognosis and follow-up, and we discussed their clinical application and how they can affect clinical decision making in the future. A literature search (from 2000 to 2021) was accomplished on MTC circulating biomarkers in different databases, and only English articles were evaluated. We found that calcitonin (CT) and carcinoembryonic antigen (CEA) are the most important circulating biomarkers in the MTC diagnosis. Other circulating biomarkers included pro-calcitonin (Pro-CT), pro-Gastrin releasing peptide (Pro-GRP), carbohydrate antigen 19-9 (CA 19-9) and chromogranin A (CgA). Some novel circulating biomarkers comprised vaspin and retinol-binding protein-4 (RBP4), myostatin, tumor cells (CTCs), RET M918T mutated cfDNA, circulating tumor DNA (ctDNA), miR-375 and Alu83 and Alu244 cfDNAs. Several circulating biomarkers have been identified to optimize the accuracy of diagnosis and offer new prognostic criteria, which should be verified before any clinical application. Although different circulating biomarkers contributed to MTC have been discovered, a few of them could be used in clinical diagnosis. In many cases, the application of each marker may not be useful lonely; therefore, a combination of two or more biomarkers could open a new avenue in the diagnosis, prognosis and prediction of MTC.

Abstract
Colorectal cancer (CRC) is a highly prevalent malignancy. Previous studies suggested that cholesterol might play a signficant role in malignant transformation and proliferation. Non-cholesterol sterols (NCS), which are transported by serum lipoproteins alongside cholesterol, are regarded as cholesterol synthesis and absorption markers. Quantification of NCS in serum and HDL fraction (NCSHDL), could provide a better insight into the cholesterol metabolism. The aim of this study was to examine the status of cholesterol synthesis and cholesterol absorption markers in serum and HDL fraction and explore their interrelation in CRC patients. Current study was designed as observational, case-control study. The study included 73 CRC patients and 95 healthy subjects. NCS and NCSHDL concentrations were determined by HPLC-MS/MS. Based on NCS and NCSHDL concentrations, different cholesterol homeostasis indices were calculated. Patients had significantly lower NCS (P<0.001) and NCSHDL concentrations (P<0.001 for desmosterolHDL; P<0.05 for lathosterolHDL, P=0.001 for campesterolHDL, P<0.001 for β-sitosterolHDL). NCSHDL/NCS (P<0.005 for desmosterolHDL/desmosterol; P<0.05 for lathosterolHDL/lathosterol; P<0.001 for both β-sitosterolHDL/β-sitosterol and campesterolHDL/campesterol) and synthesis to absorption ratio (CSI/CAI) (P<0.005) were increased in CRC patients. Additionally, low serum concentrations of desmosterol (P<0.001; OR=0.329; 95%CI (0.199-0.542)) and campesterol (P<0.001; OR=0.540; 95%CI (0.424-0.687)) were independent predictors of CRC presence. Our data suggest that cholesterol homeostasis in CRC is shifted towards increased synthesis. Relative abundance of NCS in HDL particles is increased, suggesting the possible overproduction of cholesterol precursors in peripheral tissues.

The Journal of urology. 2022;(4):769-778
Abstract
PURPOSE Our goal was to review the pathway and pertinent materials leading to approval of prostate-specific membrane antigen (PSMA) scanning by the U.S. Food and Drug Administration (FDA). MATERIALS AND METHODS Beginning with the pivotal trials and working backward, we summarize the evolution of PSMA scanning, beginning with the discovery of the molecule, the mechanism of action to identify prostate cancer, the route to the present-day test and some of the major publications leading to each step of the sequence. From the thousands of PSMA articles listed on PubMed®, the present review is focused on the 4 large U.S. trials incorporating university studies of the gallium-68 compound and commercial studies of the fluorine-18 compound. The review further focuses on the role of PSMA scanning for both initial staging of prostate cancer and diagnosis of recurrent prostate cancer. RESULTS PSMA is a transmembrane-bound glycoprotein which is overexpressed by 100-1,000-fold in prostate cancer cells. Preclinical PSMA studies at Cornell and Johns Hopkins in the 1990s were followed by early human studies in Germany in the early 2010s, then pivotal clinical trials at University of California, Los Angeles and University of California, San Francisco, leading to the first FDA approval in December 2020 (68Ga-PSMA-11). In January 2021, a commercially available product (18F-DCFPyL) was approved on the basis of multisite registration trials (CONDOR and OSPREY). Sensitivity and specificity of PSMA scanning exceeds that of any other imaging method currently available for initial staging of prostate cancer and diagnosis of recurrent disease. The accuracy of PSMA scanning is attributed to the great image contrast (high signal-to-noise ratio), a property deriving from the high PSMA tracer uptake by prostate cancer cells. That property can be estimated quantitatively by a metric, the standardized uptake value. A follow-on PSMA compound, the theranostic lutetium-177, is currently pending FDA approval for treatment of metastases. CONCLUSIONS PSMA scanning is a disruptive technology that promises to transform the way prostate cancer is initially staged, recurrence is diagnosed and some advanced cases are treated.

Abstract
Bile acids (BAs) play different roles in cancer development. Some are carcinogenic and BA signaling is also involved in various metabolic, inflammatory and immune-related processes. The liver is the primary site of BA synthesis. Liver dysfunction and microbiome compositional changes, such as during hepatocellular carcinoma (HCC) development, may modulate BA metabolism increasing concentration of carcinogenic BAs. Observations from prospective cohorts are sparse. We conducted a study (233 HCC case-control pairs) nested within a large observational prospective cohort with blood samples taken at recruitment when healthy with follow-up over time for later cancer development. A targeted metabolomics method was used to quantify 17 BAs (primary/secondary/tertiary; conjugated/unconjugated) in prediagnostic plasma. Odd ratios (OR) for HCC risk associations were calculated by multivariable conditional logistic regression models. Positive HCC risk associations were observed for the molar sum of all BAs (ORdoubling = 2.30, 95% confidence intervals [CI]: 1.76-3.00), and choline- and taurine-conjugated BAs. Relative concentrations of BAs showed positive HCC risk associations for glycoholic acid and most taurine-conjugated BAs. We observe an association between increased HCC risk and higher levels of major circulating BAs, from several years prior to tumor diagnosis and after multivariable adjustment for confounders and liver functionality. Increase in BA concentration is accompanied by a shift in BA profile toward higher proportions of taurine-conjugated BAs, indicating early alterations of BA metabolism with HCC development. Future studies are needed to assess BA profiles for improved stratification of patients at high HCC risk and to determine whether supplementation with certain BAs may ameliorate liver dysfunction.
