J Surg Res 2024; 295:423-430. [PMID: 38070256 DOI: 10.1016/j.jss.2023.11.040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Revised: 10/17/2023] [Accepted: 11/12/2023] [Indexed: 02/25/2024]
Abstract
INTRODUCTION Surveillance following sacrococcygeal teratoma (SCT) resection varies. The purpose of this study was to describe the clinical characteristics and outcomes of patients undergoing SCT resection and examine current institutional practices to detect recurrence. METHODS A single-institution retrospective review of children who underwent resection of an SCT from January 1, 2010 to December 31, 2020 was performed. Data were summarized and surveillance strategies compared between histopathologic subtypes using nonparametric methods. RESULTS Thirty six patients (75.0% female) underwent SCT removal at a median age of 8 d. Histopathology revealed 27 mature teratomas (75.0%), eight immature teratomas (22.2%), and one malignant germ cell tumor (2.8%). Median postoperative follow-up was 3.17 y (interquartile range [IQR]: 2.31-4.38 y). Patients had a median of 2.32 clinic visits per year (IQR: 2.00-2.70), alpha-fetoprotein levels were obtained at a median of 2.01 times per year (IQR: 0-1.66), and surveillance imaging was performed at a median of 2.31 times per year (IQR: 0-2.84). Patients with immature teratomas had alpha-fetoprotein laboratories obtained more frequently than patients with mature teratomas (3.10 times/year versus 0.93 times/year, P = 0.001). There was no significant difference in the number of imaging studies obtained between groups. Two patients (5.6%) developed recurrence, which were identified on magnetic resonance imaging at 191 and 104 d postresection, respectively. CONCLUSIONS Postoperative surveillance practices varied widely. Recurrence was noted in a single malignant case in the first year following resection. Multi-institutional studies are needed to determine the optimal surveillance strategy to detect recurrence of SCT.

The Diagnostic Accuracy of Serum Alpha-Fetoprotein Levels in Follow-up for Recurrence of Sacrococcygeal Teratoma; a Nationwide Review of SCT Cases in the Netherlands. J Pediatr Surg 2024:S0022-3468(24)00080-0. [PMID: 38418277 DOI: 10.1016/j.jpedsurg.2024.01.048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/20/2024] [Accepted: 01/31/2024] [Indexed: 03/01/2024]
Abstract
BACKGROUND Serum alpha-fetoprotein (AFP) is often used as tumour marker for recurrent sacrococcygeal teratoma (SCT). We aimed to assess the normal dynamics of serum AFP levels after initial resection and diagnostic accuracy of serum AFP levels the follow-up for recurrence in SCT. METHODS This retrospective study included 57 patients treated for SCT in the six pediatric surgical centers in the Netherlands from 1980 to 2018. MAIN RESULTS 57 patients were included in the study of whom 19 children developed 20 recurrences at a median of 14.0 months after initial resection. No significant difference was found in serum AFP level dynamics between the recurrence and non-recurrence group after initial resection (p = 0.950). Serum AFP levels did not significantly increase before recurrence (p = 0.106) compared to serum AFP levels of children without recurrence at the same time. However, serum AFP levels did significantly increase in malignant recurrences (n = 7) (p = 0.03) compared to patients without recurrence. A cut-off value of 55 μg/L was found to be predictive for recurrent SCT with an Area Under the Curve (AUC) of 0.636 with sensitivity of 50% and specificity of 100%. CONCLUSION Dynamics of serum AFP levels are not different between patients with and without recurrence after initial resection of SCT. Serum AFP levels are not predictive for mature or immature recurrent SCT and normal AFP levels do not rule out recurrent SCT. However, serum AFP levels exceeding 55 μg/L can indicate recurrent SCT, especially malignant recurrences.

Abstract
Alpha-fetoprotein (AFP) is a commonly used clinical biomarker. Before 1970, the two-way agar diffusion method was mainly used, and the specificity of AFP in the diagnosis of primary liver cancer was satisfactory. However, its positivity rate was not very high. The diagnostic value of AFP is changing with the evolution of detection methods. Here, we performed a literature search to identify English-language publications. The search was performed from January 2015 to April 2023 using the PubMed database and the following terms in [Titles/Abstracts]: alpha-fetoprotein, clinical practice, detection, etc. The references of retrieved articles were also screened to broaden the search. Studies referring to liver cancer and AFP detection methods were excluded. In this review, several clinical application scenarios for AFP were systematically reviewed, and its potential detection value in the future was discussed.

Pediatric reference interval verification for 17 specialized immunoassays and cancer markers on the Abbott Alinity i system in the CALIPER cohort of healthy children and adolescents. Clin Chem Lab Med 2023; 61:123-132. [PMID: 36117243 PMCID: PMC9691267 DOI: 10.1515/cclm-2022-0709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 09/09/2022] [Indexed: 12/15/2022]
Abstract
OBJECTIVES Clinical laboratory investigation of autoimmune, metabolic, and oncologic disorders in children and adolescents relies on appropriateness of reference intervals (RIs). The Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER) previously established comprehensive pediatric RIs for specialized immunoassays on the Abbott ARCHITECT system. Herein, we aim to verify performance on new Alinity i assays by evaluating sera collected from healthy children as per Clinical and Laboratory Standards Institute (CLSI) EP-28A3C guidelines. METHODS Precision, linearity, and method comparison experiments were completed for 17 specialized Alinity immunoassays, including cancer antigens, autoimmune peptides, and hormones. Sera collected from healthy children and adolescents (birth-18 years, n=100) were evaluated. CLSI-based verification was completed using previously established CALIPER RIs for ARCHITECT assays as the reference. RESULTS Of 17 specialized immunoassays assays, only anti-cyclic citrullinated peptides (anti-CCP) did not meet acceptable verification criterion (i.e., ≥90% of results within ARCHITECT reference CI). Anti-thyroglobulin, anti-thyroid peroxidase, and carcinoembryonic antigen did not require age-specific consideration beyond one year of age, with 63, 91, and 80% of samples equalling the limit of detection, respectively. Estimates were separated by sex for relevant assays (e.g., sex hormone binding globulin, total and free prostate specific antigen). CONCLUSIONS Findings support transferability of pediatric RIs on ARCHITECT system to the Alinity system for 16 specialized immunoassays in the CALIPER cohort and will be a useful resource for pediatric clinical laboratories using Alinity assays. Further work is needed to establish evidence-based interpretative recommendations for anti-CCP and continue to evaluate pediatric RI acceptability for newly available assay technologies.

Abstract
A biomarker is a measurable indicator used to distinguish precisely/objectively either normal biological state/pathological condition/response to a specific therapeutic intervention. The use of novel molecular biomarkers within evidence-based medicine may improve the diagnosis/treatment of disease, improve health outcomes, and reduce the disease's socio-economic impact. Presently cancer biomarkers are the backbone of therapy, with greater efficacy and better survival rates. Cancer biomarkers are extensively used to treat cancer and monitor the disease's progress, drug response, relapses, and drug resistance. The highest percent of all biomarkers explored are in the domain of cancer. Extensive research using various methods/tissues is carried out for identifying biomarkers for early detection, which has been mostly unsuccessful. The quantitative/qualitative detection of various biomarkers in different tissues should ideally be done in accordance with qualification rules laid down by the Early Detection Research Network (EDRN), Program for the Assessment of Clinical Cancer Tests (PACCT), and National Academy of Clinical Biochemistry. Many biomarkers are presently under investigation, but lacunae lie in the biomarker's sensitivity and specificity. An ideal biomarker should be quantifiable, reliable, of considerable high/low expression, correlate with the outcome progression, cost-effective, and consistent across gender and ethnic groups. Further, we also highlight that these biomarkers' application remains questionable in childhood malignancies due to the lack of reference values in the pediatric population. The development of a cancer biomarker stands very challenging due to its complexity and sensitivity/resistance to the therapy. In past decades, the cross-talks between molecular pathways have been targeted to study the nature of cancer. To generate sensitive and specific biomarkers representing the pathogenesis of specific cancer, predicting the treatment responses and outcomes would necessitate inclusion of multiple biomarkers.

Abstract
BACKGROUND The incidence of children developing recurrent sacrococcygeal teratoma (SCT) is 2-35%. Serum alpha-fetoprotein (AFP) is often used as a tumor marker for (malignant) recurrences of SCT and could potentially be used during routine follow-up after SCT resection. However, the diagnostic accuracy of serum AFP levels during follow-up has not been well established. Therefore, we aimed to systematically review the diagnostic accuracy of serum AFP levels in recurrent SCT. METHODS We queried Search Premier, COCHRANE Library, EMCARE, EMBASE, PubMed, ScienceDirect and Web of Science databases to identify studies regarding patients with SCT with follow-up using serum AFP levels postoperative. We estimated sensitivity and specificity of serum AFP levels. RESULTS Fifteen studies (613 patients, 121 recurrences) were included and these mainly described serum AFP levels in patients with recurrent SCT (n = 111); 83 (75%) patients with recurrent SCT had elevated serum AFP levels. A subgroup analysis of articles that measured serum AFP levels in all patients (n = 6, 136 patients, 14 recurrences) showed a sensitivity and specificity of 79% and 95%, respectively. The sensitivity of AFP levels to detect malignant recurrence was 96%. CONCLUSION Diagnostic accuracy of serum AFP levels to detect recurrent SCT seems promising, though sensitivity could be overestimated since serum AFP levels are mainly described in patients with elevated AFP levels or at recurrent SCT. Furthermore, serum AFP levels could be helpful to detect malignant recurrences. TYPE OF STUDY Systematic review of level 2-4 studies. LEVEL OF EVIDENCE Level 2-4 (mostly level 2).

Abstract
Aim The aims of this study were to evaluate health-related quality of life (HRQoL) in children with sacrococcygeal teratoma and to explore the effect of the scar on physical, emotional and behavioral aspects. Methods A cohort of children operated on for sacrococcygeal teratoma between 2000 and 2013 at Lund University Hospital, Sweden, and their parents were interviewed. HRQoL was evaluated with PedsQL, and scar satisfaction was estimated through Patient Observer Scar Assessment Score (POSA). Results All eligible children (n = 17) were included (100% response rate). Median age was 7.3 years (range 3.5–16.0). Mean total PedsQL score was 92.3 (range 72.0 to 99.0). Patients with comorbidity scored lower (87.5) than those without (95.0) (p < 0.05). Pain during sitting down was reported by two (20%) patients, and itching was reported by another two patients (20%) aged > 8 years. No children reported that they avoided situations due to the scar, and most (80% of children and 90% of parents) reported absent or only mild negative emotions when considering the scar. Conclusion Children with sacrococcygeal teratoma had a good overall HRQoL, but comorbidity reduced the outcome. A few children reported scar-related impact on physical, behavioral and emotional aspects.

Abstract
Results There were no differences found in the HE4 levels determined for the mothers' blood samples and umbilical cord blood samples in all investigated groups. In comparison with healthy children, the elevated HE4 levels were observed in neonates with TTN. Significant positive correlation between HE4 and CRP as well as PCT levels was observed in all investigated neonates. The receiver operating characteristic (ROC) curve analysis demonstrated the cut-off value for the serum HE4 in the researched neonates at the level of 318.5 pmol/L, yielding the sensitivity of 73.9% and specificity of 66.7% for the early diagnosis of TTN. Conclusions Serum HE4 could be considered as a candidate biomarker for the early diagnosis of pulmonary dysfunction in the newborns.

Abstract
Abstract
Background
The diagnostic utility of laboratory tests in paediatric medicine relies heavily on the availability of appropriate reference intervals (RIs). The Canadian Laboratory Initiative on Paediatric Reference Intervals (CALIPER) has established a comprehensive database of covariate-stratified RIs for many paediatric laboratory tests using a large, healthy reference population. Several automated analysers in widespread use in clinical laboratories have already been studied. Here, we extend the testing to Roche immunoassays and report, for the first time, comprehensive paediatric RIs for 17 endocrine and special chemistry markers.
Methods
A total of 741 healthy children and adolescents (1 day to <19 years) were recruited and serum samples were analysed for 17 immunoassays on the Roche cobas 8000 e602 Immunoassay Analyzer. Age and sex-specific RIs were established and corresponding 90% confidence intervals (CIs) were calculated in accordance with Clinical and Laboratory Standards Institute guidelines.
Results
Reference values for all analytes measured required age partitioning, particularly during early life and throughout adolescence. Of the 17 analytes measured, eight required sex partitioning, including ferritin, thyroid stimulating hormone (TSH), total triiodothyronine (TT3) and all fertility/sex hormones, except prolactin.
Conclusions
This is the first study to determine accurate paediatric RIs for Roche immunoassays. RIs were generally similar to those previously published by CALIPER on other analytical platforms, highlighting the reproducibility of age- and sex-specific trends in reference values observed across the paediatric age range. The RIs established in this study will improve the accuracy of test result interpretation and clinical decision-making in clinical laboratories utilising Roche immunoassays.

Abstract
Sacrococcygeal teratoma is the most common germ cell neoplasia that consists of tissues derived from primitive germ layers. Approximately 10-20% of patients are malignant. Because of the high rate of recurrence, treatment strategies for malignant sacrococcygeal teratomas are limited. Hence, we report a case of malignant sacrococcygeal teratoma treated with concurrent chemoradiotherapy plus adjuvant chemotherapy and review the literature. This case report indicates that chemoradiation plus adjuvant chemotherapy may be a treatment option for malignant SCT which is not technically resectable or with residual lesion after surgery.

Abstract
BACKGROUND Sacrococcygeal teratoma (SCT) is the most common extragonadal germ cell tumor in neonates and infants. Although most cases of infantile SCT are benign tumors by nature, some develop into extremely large lesions, leading to massive bleeding, high-output heart failure, disseminated intravascular coagulation, and even fatal outcomes during the neonatal period. In addition, some patients may present with tumor recurrence, malignant transformation, long-term sequelae (including bladder and bowel dysfunction) and lower leg palsy during the long-term follow up. SCT, however, is very rare, and there are few opportunities to encounter this disease, therefore general physicians without expert credentials currently lack information relevant to clinical practice. For this reason, the research project committee has compiled guidelines concerning SCT. METHODS The purpose of these guidelines was to share information concerning the treatment and follow up of infantile SCT. The guidelines were developed using the methodologies in the Medical Information Network Distribution System. A comprehensive search of the English- and Japanese-language articles in PubMed and Ichu-Shi Web identified only case reports or case series, and the recommendations were developed through a process of informal consensus. RESULTS The clinical questions addressed the risk factors, the efficacy of cesarean section, the initial devascularization of tumor feeding vessels, interventional radiology, recommended clinical studies for follow up and possible long-term complications. CONCLUSIONS These are the first guidelines for SCT to be established in Japan, and they may have huge clinical value and significance in terms of developing therapeutic strategies and follow up, potentially contributing to the improvement of the prognosis and quality of life of SCT patients.

Half-life of alpha-fetoprotein in neonatal sacrococcygeal teratoma. J Pediatr Surg 2018; 53:2470-2474. [PMID: 30249359 DOI: 10.1016/j.jpedsurg.2018.08.012] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2018] [Accepted: 08/25/2018] [Indexed: 11/23/2022]
Abstract
BACKGROUND Alpha-fetoprotein (AFP) is useful as a tumor marker for sacrococcygeal teratoma (SCT). We investigated the half-life of AFP in SCT. METHODS Neonates who underwent surgical treatment for SCT between 1997 and 2016 were included in the study, whereas patients who died before or after surgery or had malignant germ cell tumors were excluded. RESULTS Fifty-five non-recurrent SCT patients (M:F = 18:37) were enrolled. They underwent surgery on average 7.4 ± 4.1 days after birth. Serum AFP was measured an average 4.25 ± 2.07 times per patient. We obtained 165 half-lives following the formula (M = Mo * (1/2) Δt/T). A positive correlation was observed between half-life and patient age using the formula T1/2 = 0.0597 × days +6.1643 (p < 0.001). It was different from recurrent SCT (T1/2 = 0.1196 × days -0.0633) (p < 0.05). Half-life was different between mature SCT (T1/2 = 0.0671 × days +4.3912) and immature SCT (T1/2 = 0.0433 × days +8.9339) (p < 0.05). CONCLUSION The half-life of AFP in neonatal patients with SCT was prolonged in proportion to the age, and it was getting longer in recurrent tumor than non-recurrent tumor. The half-life of AFP was longer in immature teratoma than in mature teratoma. LEVEL OF EVIDENCE IV.

Abstract
Abstract
Background
Measurement of α-fetoprotein (AFP) concentrations in the serum of infants is useful for the management of testicular germ cell tumors, hepatoblastoma and hepatocellular carcinoma. Here, we provide a critical review of the available information about pediatric reference intervals (RI), focusing on their utility in interpreting AFP as an aid for cancer diagnosis.
Content
Evidence sources in the available literature were critically appraised. Out of 3873 retrieved papers, 24 were finally selected and carefully inspected, and six of them overcame exclusion criteria (i.e. methodological limitations in the study design, statistical gaps, drawbacks in traceability of the AFP assay to higher order materials and/or biased reporting of AFP results). Preterm and term infants up to the 3rd month of life exhibited the highest average AFP concentrations, but the attempt of defining RI by data pooling and partitioning for age intervals was impeded by the wide variability of data. The inability of defining robust RI in the first months of life made difficult, if not impossible, using upper reference limits for ruling out malignancies with a single AFP result. Evaluating the behavior of AFP concentrations 5 days from the baseline result, if this exceeds risk thresholds partitioned for age, according to the formula Xt=X0*2−t/HL (where: t=days elapsed for AFP retest; HL=AFP half-life according to age; X0=AFP baseline concentration, and Xt=predicted AFP concentration at day 5), could give a better information.
Summary
Novel studies defining AFP RI in infants based on robust methodology are warranted to improve the interpretation of AFP results in pediatric oncology. In the meantime, algorithms based on both serum AFP absolute concentrations and HL may aid in cancer diagnosis.

Abstract
BACKGROUND Sacrococcygeal teratoma (SCT) is a rare congenital tumor associated with high rates of perinatal mortality and morbidity. This study evaluated the incidence, prenatal detection rate, and early predictors of a complicated outcome following diagnosis of SCT. METHODS We retrospectively identified all fetuses and newborns diagnosed with SCT in southern Sweden from 2000 to 2013. Prenatal sonograms, charts, and pathology reports were reviewed and analyzed. Each case of SCT was defined as complicated or uncomplicated based on the postnatal outcome. All cases with a fatal outcome or that required cardiac resuscitation during birth or surgery were classified as complicated. RESULTS The overall incidence of SCT was 1:13,982 (19 children in a cohort of 265,658 live births). A prenatal diagnosis was made in 74% of cases, there were no stillbirths or intrauterine deaths, and the overall mortality rate was 11%. Four cases of SCT (21%) were classified as complicated, and these cases had a significantly larger tumor size at gestational week 20 (P=0.048), had a significantly higher tumor growth rate (P=0.003), and were more often associated with polyhydramnios (P=0.01), and mainly solid/mixed morphology (P=0.001). CONCLUSIONS The incidence of SCT in southern Sweden was higher than those reported in most previous studies; however, the associated mortality rate was relatively low. Fetuses with large tumors, rapidly growing tumors, and polyhydramnios were more likely to experience a complicated outcome during the postnatal period.

Abstract
Neonatal teratomas, not common in clinical, are often some case reports, female more than male, most are benign. It can occur anywhere of body midline; sacrococcygeal teratoma is the most common and the second most frequent site of extragonadal teratomas is mediastinum. Benign is more commom and malignant is very rarely seen. Completely surgical resection is the main and effective treatment. This review reports a case of neonatal teratoma, which is complicated with a fatal phrenic nerve palsy after surgery.

Abstract
Abstract
BACKGROUND
Cancer biomarkers are commonly used in pediatrics to monitor cancer progression, recurrence, and prognosis, but pediatric reference value distributions have not been well established for these markers. The Canadian Laboratory Initiative on Pediatric Reference Intervals (CALIPER) sought to develop a pediatric database of covariate-stratified reference value distributions for 11 key circulating tumor markers, including those used in assessment of patients with childhood or adult cancers.
METHODS
Healthy community children from birth to 18 years of age were recruited to participate in the CALIPER project with informed parental consent. We analyzed serum samples from 400–700 children (depending on the analyte in question) on the Abbott Architect ci4100 and established reference intervals for α-fetoprotein (AFP), antithyroglobulin (anti-Tg), human epididymis protein 4 (HE4), cancer antigen 125 (CA125), CA15-3, CA19-9, progastrin-releasing peptide (proGRP), carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC), and total and free prostate specific antigen (PSA) according to CLSI C28-A3 statistical guidelines.
RESULTS
We observed significant fluctuations in biomarker concentrations by age and/or sex in 10 of 11 biomarkers investigated. Age partitioning was required for CA153, CA125, CA19-9, CEA, SCC, proGRP, total and free PSA, HE4, and AFP, whereas sex partitioning was also required for CA125, CA19-9, and total and free PSA.
CONCLUSIONS
This CALIPER study established a database of childhood reference intervals for 11 tumor biomarkers and revealed dramatic fluctuations in tumor marker concentrations between boys and girls and throughout childhood. In addition, important differences between the adult and pediatric population were observed, further highlighting the need for pediatric-specific reference intervals.

Abstract
Mucins and mucin-type glycoproteins, collectively referred to as mucin-type O-glycans, are implicated in many important biological functions and pathological conditions, including malignancy. Presently, there is no reliable method to measure the total mucin-type O-glycans of a sample, which may contain one or more of these macromolecules of unknown structures. We report the development of an improved microassay that is based on the binding of lectins to the unique and constant GalNAc-Ser/Thr structural feature of mucin-type O-glycans. Since the sugar-amino acid linkage in the mucin-type O-glycans is invariably cryptic, we first chemically removed the heterogeneous peripheral and core saccharides of model glycoconjugates before examining for their interactions using an enzyme-linked lectin assay (ELLA). Desialylation of the model glycoconjugates led to maximal binding of the lectins but additional treatments such as Smith degradation did not result in increased binding. Of the lectins tested for their ability to probe the desialylated O-glycans, jacalin showed the highest sensitivity followed by champedak galactose binding (CGB) lectin and Vicia villosa agglutinin. Further improvement in the sensitivity of ELLA was achieved by using microtiter plates that were pre-coated with the CGB lectin, which increased the specificity of the assay to mucin-type O-glycans. Finally, the applicability of the developed sandwich ELLA to crude samples was demonstrated by estimating trace quantities of the mucin-type O-glycans in the human serum.
