RESUMEN

Although blood autoantibodies were initially associated with autoimmune diseases, multiple evidence have been accumulated showing their presence in many types of cancer. This has opened their use in clinics, since cancer autoantibodies might be useful for early detection, prognosis, and monitoring of cancer patients. In this review, we discuss the different techniques available for their discovery and validation. Additionally, we discuss here in detail those autoantibody panels verified in at least two different reports that should be more likely to be specific of each of the four most incident cancers. We also report the recent developed kits for breast and lung cancer detection mostly based on autoantibodies and the identification of novel therapeutic targets because of the screening of the cancer humoral immune response. Finally, we discuss unsolved issues that still need to be addressed for the implementation of cancer autoantibodies in clinical routine for cancer diagnosis, prognosis, and/or monitoring.

RESUMEN

Importance: US cancer diagnoses were substantially lower than expected during the COVID-19 pandemic in 2020. A national study on the extent to which rates recovered in 2021 has not yet been conducted. Objective: To examine observed vs expected cancer rate trends for January 2020 to December 2021. Design, Setting, and Participants: This cross-sectional, population-based study of cancer incidence trends used the Surveillance, Epidemiology, and End Results 22 (SEER-22) Registries Database, which covers 47.9% of the US population. Included individuals were those with an invasive cancer diagnosis reported to registries included in SEER-22 between January 1, 2000, and December 31, 2021. Exposures: Age, sex, race and ethnicity, urbanicity, and stage at diagnosis. Main Outcomes and Measures: Expected cancer incidence rates were measured for the COVID-19 pandemic years of 2020 and 2021 from prepandemic trends using ensemble forecasting methods. Relative difference between observed and expected cancer incidence rates and numbers of potentially missed cases were measured. Results: The SEER-22 registries reported 1 578 697 cancer cases in 2020 and 2021, including 798 765 among male individuals (50.6%) and 909 654 among persons aged 65 years or older (57.6%). Observed all-sites cancer incidence rates were lower than expected by 9.4% in 2020 (95% prediction interval [PI], 8.5%-10.5%), lower than expected by 2.7% in 2021 (95% PI, 1.4%-3.9%), and lower than expected by 6.0% across both years combined (95% PI, 5.1%-7.1%), resulting in 149 577 potentially undiagnosed cancer cases (95% PI, 126 059-176 970). Of the 4 screening-detected cancers, only female breast cancer showed significant recovery in 2021, exceeding expected rates by 2.5% (95% PI, 0.1%-4.8%), while significant reductions remained for lung cancer (9.1% lower than expected; 95% PI, 6.4%-13.2%) and cervical cancer (4.5% lower than expected; 95% PI, 0.4%-8.0%), particularly for early stage at diagnosis. Rates of all-sites cancer incidence returned to prepandemic trends in 2021 among female individuals, persons aged younger than 65 years, and persons of non-Hispanic Asian and Pacific Islander race and ethnicity. Conclusions and Relevance: This population-based cross-sectional study of US cancer incidence trends found that rates of diagnosis improved in 2021 but continued to be lower than expected, adding to the existing deficit of diagnosed cases from 2020. Particular attention should be directed at strategies to immediately increase cancer screenings to make up lost ground.

RESUMEN

Modern cancer research depends heavily on the identification and validation of biomarkers because they provide important information about the diagnosis, prognosis, and response to treatment of the cancer. This review will provide a comprehensive overview of cancer biomarkers, including their development phases and recent breakthroughs in transcriptomics and computational techniques for detecting these biomarkers. Blood-based biomarkers have great potential for non-invasive tumor dynamics and treatment response monitoring. These include circulating tumor DNA, exosomes, and microRNAs. Comprehensive molecular profiles are provided by multi-omic technologies, which combine proteomics, metabolomics, and genomes to support the identification of biomarkers and the targeting of therapeutic interventions. Genetic changes are detected by next-generation sequencing, and patterns of protein expression are found by protein arrays and mass spectrometry. Tumor heterogeneity and clonal evolution can be understood using metabolic profiling and single-cell studies. It is projected that the use of several biomarkers-genetic, protein, mRNA, microRNA, and DNA profiles, among others-will rise, enabling multi-biomarker analysis and improving individualised treatment plans. Biomarker identification and patient outcome prediction are further improved by developments in AI algorithms and imaging techniques. Robust biomarker validation and reproducibility require cooperation between industry, academia, and doctors. Biomarkers can provide individualized care, meet unmet clinical needs, and enhance patient outcomes despite some obstacles. Precision medicine will continue to take shape as scientific research advances and the integration of biomarkers with cutting-edge technologies continues to offer a more promising future for personalized cancer care.

RESUMEN

Instruction-tuned large language models (LLMs) demonstrate exceptional ability to align with human intentions. We present an LLM-based model-instruction-tuned LLM for assessment of cancer (iLLMAC)-that can detect cancer using cell-free deoxyribonucleic acid (cfDNA) end-motif profiles. Developed on plasma cfDNA sequencing data from 1135 cancer patients and 1106 controls across three datasets, iLLMAC achieved area under the receiver operating curve (AUROC) of 0.866 [95% confidence interval (CI), 0.773-0.959] for cancer diagnosis and 0.924 (95% CI, 0.841-1.0) for hepatocellular carcinoma (HCC) detection using 16 end-motifs. Performance increased with more motifs, reaching 0.886 (95% CI, 0.794-0.977) and 0.956 (95% CI, 0.89-1.0) for cancer diagnosis and HCC detection, respectively, with 64 end-motifs. On an external-testing set, iLLMAC achieved AUROC of 0.912 (95% CI, 0.849-0.976) for cancer diagnosis and 0.938 (95% CI, 0.885-0.992) for HCC detection with 64 end-motifs, significantly outperforming benchmarked methods. Furthermore, iLLMAC achieved high classification performance on datasets with bisulfite and 5-hydroxymethylcytosine sequencing. Our study highlights the effectiveness of LLM-based instruction-tuning for cfDNA-based cancer detection.

RESUMEN

Before implementing a biomarker in routine clinical care, it must demonstrate clinical utility by leading to clinical actions that positively affect patient-relevant outcomes. Randomly controlled early detection utility trials, especially those targeting mortality endpoint, are challenging due to their high costs and prolonged duration. Special design considerations are required to determine the clinical utility of early detection assays. This commentary reports on discussions among the National Cancer Institute's Early Detection Research Network investigators, outlining the recommended process for carrying out single-organ biomarker-driven clinical utility studies. We present the early detection utility studies in the context of phased biomarker development. We describe aspects of the studies related to the features of biomarker tests, the clinical context of endpoints, the performance criteria for later phase evaluation, and study size. We discuss novel adaptive design approaches for improving the efficiency and practicality of clinical utility trials. We recommend using multiple strategies, including adopting real-world evidence, emulated trials, and mathematical modeling to circumvent the challenges in conducting early detection utility trials.

RESUMEN

PURPOSE: To evaluate the relative diagnostic yield of clinical germline genomic tests in a diverse pediatric cancer population. PATIENTS AND METHODS: The KidsCanSeq study enrolled pediatric cancer patients across six sites in Texas. Germline analysis included both exome sequencing and a therapy-focused pediatric cancer gene panel. The results were categorized by participants demographics, the presence of pathogenic or likely pathogenic (P/LP) variants, and variants of uncertain significance (VUS) in cancer predisposition genes (CPGs). Pediatric actionable CPGs were defined as those with cancer surveillance recommendations during childhood. RESULTS: Cancer P/LP variants were reported by at least one platform in 103 of 578 (17.8%) participants of which 76 were dominant cancer genes (13.1%) with no significant differences by self-described race or Hispanic ethnicity. However, the proportion of participants with VUS was greater in Asian and African American participants (P = .0029). Diagnostic yield was 16.6% for exome versus 8.5% for panel (P < .0001) with 42 participants with concordant germline results. Exome-only results included P/LP variants in 30 different CPGs in 54 participants, whereas panel-only results included seven participants with a copy number or structural P/LP variants in CPGs. There was no significant difference in diagnostic yield limited to pediatric actionable CPGs (P = .6171). CONCLUSION: Approximately 18% of a diverse pediatric cancer population had germline diagnostic findings with 50% of P/LP variants reported by only one platform because of CPGs not on the targeted panel and copy number variants (CNVs)/rearrangements not reported by exome. Although diagnostic yields were similar in this diverse population, increases in VUS results were observed in Asian and African American populations. Given the clinical significance of CNVs/rearrangements in this cohort, detection is critical to optimize germline analysis of pediatric cancer populations.

RESUMEN

HNRNPA2B1 is a member of the HNRNP family, which is associated with telomere function, mRNA translation, and splicing, and plays an important role in tumor development. To date, there have been no pan-cancer studies of HNRNPA2B1, particularly within the TME. Therefore, we conducted a pan-cancer analysis of HNRNPA2B1 using TCGA data. Based on datasets from TCGA, TARGET, Genotype-Tissue Expression, and Human Protein Atlas, we employed a range of bioinformatics approaches to explore the potential oncogenic role of HNRNPA2B1. This included analyzing the association of HNRNPA2B1 expression with prognosis, tumor mutation burden (TMB), microsatellite instability (MSI), immune response, and immune cell infiltration of individual tumors. We further validated the bioinformatic findings using immunohistochemistry techniques. HNRNPA2B1 was found to be differentially expressed across most tumor types in TCGA's pan-cancer database and was predictive of poorer clinical staging and survival status. HNRNPA2B1 expression was also closely linked to TMB, MSI, tumor stemness, and chemotherapy response. HNRNPA2B1 plays a significant role in the TME and is involved in the regulation of novel immunotherapies. Its expression is significantly associated with the infiltration of macrophages, dendritic cells, NK cells, and T cells. Furthermore, HNRNPA2B1 is closely associated with immune checkpoints, immune-stimulatory genes, immune-inhibitory genes, MHC genes, chemokines, and chemokine receptors. We performed a comprehensive evaluation of HNRNPA2B1, revealing its potential role as a prognostic indicator for patients and its immunomodulatory functions.

RESUMEN

OBJECTIVES: Cancer is a leading cause of death in unhoused adults. We sought to examine the association between housing status, stage at diagnosis and all-cause survival following cancer diagnosis at a public hospital. DESIGN: Retrospective cohort study examining new cancer diagnoses between 1 July 2011 and 30 June 2021. SETTING: A public hospital in San Francisco. EXPOSURE: Housing status (housed, formerly unhoused, unhoused) was ascertained via a county-wide integrated dataset that tracks both observed and reported homelessness. METHODS: We reported univariate analyses to investigate differences in demographic and clinical characteristics by housing group. We then constructed Kaplan-Meier curves stratified by housing group to examine unadjusted all-cause mortality. Finally, we used multivariable Cox proportional hazards models to compare the hazard rate of mortality for each housing status group, adjusting for demographic and clinical factors. RESULTS: Our cohort included 5123 patients with new cancer diagnoses, with 4062 (79%) in housed patients, 623 (12%) in formerly unhoused patients and 438 (9%) in unhoused patients. Unhoused and formerly unhoused patients were more commonly diagnosed with stage 4 disease (28% and 27% of the time, respectively, vs 22% of housed patients). After adjusting for demographic and clinical characteristics, unhoused patients with stage 0-3 disease had a 50% increased hazard of death (adjusted HR (aHR) 1.5, 95% CI 1.1 to 1.9; p<0.004) as did formerly unhoused patients (aHR 1.5, 95% CI 1.2 to 1.9; p=0.001) compared with housed individuals 3 months after diagnosis. CONCLUSIONS: Unhoused and formerly unhoused patients diagnosed with non-metastatic cancer had substantially increased hazards of death compared with housed patients cared for in a public hospital setting. Current or former lack of housing could contribute to poor outcomes following cancer diagnoses via multiple mechanisms.

RESUMEN

BACKGROUND/AIM: The soluble interleukin-2 receptor (sIL-2R) serve as a valuable biomarker for tumors in human patients, as its levels increase during the activation of T lymphocytes in clinical states such as inflammation, infection, and tumor. This study aimed to demonstrate that sIL-2R levels can be also elevated in dogs with tumors and evaluate its applicability as a diagnostic and prognostic factor in canine cancer patients. PATIENTS AND METHODS: Serum was collected from 6 healthy dogs and 34 dogs with solid tumors. The concentration of sIL-2R was measured using a commercial enzyme-linked immunosorbent assay kit. RESULTS: The median sIL-2R concentration was significantly higher in dogs with solid masses than in healthy dogs (117.3 vs 68.33 pg/ml, p = 0.016). The highest median sIL-2R concentration was found in dogs with malignant tumors, followed by those with benign tumors, and healthy dogs (119.6 vs 93.74 vs 68.33 pg/ml, respectively). In dogs with malignant tumors, the mortality rate was significantly higher in the group with high sIL-2R levels than in the group with low sIL-2R levels. Dogs with solid tumors, particularly those with malignant tumors, had higher concentrations of sIL-2R than healthy dogs. Among dogs with malignant tumors, a correlation between sIL-2R concentration and mortality rate was confirmed. CONCLUSION: Serum sIL-2R levels may be used to detect malignant tumors and serve as a prognostic factor in dogs with malignant tumors.

RESUMEN

BACKGROUND: Cancer predisposition syndromes (CPS) impact about 10% of patients with pediatric cancer. Genetic testing (CPS-GT) has multiple benefits, but few studies have described parent and child knowledge and attitudes regarding CPS-GT decision-making. This study examined parent and patient CPS-GT decision-making knowledge and attitudes. PROCEDURE: English- or Spanish-speaking parents of children with pediatric cancer and patients with pediatric cancer ages 15-18 within 12 months of diagnosis or relapse were eligible to participate. Seventy-five parents and 19 parent-patient dyads (N = 94 parents, 77.7% female, 43.6% Latino/a/Hispanic; 19 patients, 31.6% female) completed surveys measuring CPS-GT-related beliefs. Independent samples t-tests compared parent responses across sociodemographic characteristics and parent-patient responses within dyads. RESULTS: Spanish-speaking parents were significantly more likely than English-speaking parents to believe that CPS-GT not being helpful (p < .001) and possibly causing personal distress (p = .002) were important considerations for deciding whether to obtain CPS-GT. Parents with less than four-year university education, income less than $75,000, or Medicaid (vs. private insurance) were significantly more likely to endorse that CPS-GT not being helpful was an important consideration for deciding whether to obtain CPS-GT (p < .001). Parents felt more strongly than patients that they understood what CPS-GT was (p = .01) and that parents should decide whether patients under 18 should receive CPS-GT (p = .002). CONCLUSIONS: Spanish-speaking parents and parents with lower socioeconomic statuses were more strongly influenced by the potential disadvantages of CPS-GT in CPS-GT decision-making. Parents felt more strongly than patients that parents should make CPS-GT decisions. Future studies should investigate mechanisms behind these differences and how to best support CPS-GT knowledge and decision-making.

RESUMEN

The current constraints associated with cancer diagnosis and molecular profiling, which rely on invasive tissue biopsies or clinical imaging, have spurred the emergence of the liquid biopsy field. Liquid biopsy involves the extraction of circulating tumor cells (CTCs), circulating free or circulating tumor DNA (cfDNA or ctDNA), circulating cell-free RNA (cfRNA), extracellular vesicles (EVs), and tumor-educated platelets (TEPs) from bodily fluid samples. Subsequently, these components undergo molecular characterization to identify biomarkers that are critical for early cancer detection, prognosis, therapeutic assessment, and post-treatment monitoring. These innovative biosources exhibit characteristics analogous to those of the primary tumor from which they originate or interact. This review comprehensively explores the diverse technologies and methodologies employed for processing these biosources, along with their principal clinical applications.

RESUMEN

BACKGROUND: Despite the severe impact of COVID-19 on cancer patients, data on COVID-19 outcomes in cancer patients from low- and middle-income countries is limited. We conducted a large study about the mortality rate of COVID-19 in cancer patients in Iran. METHODS: We analyzed data from 1,079 cancer (average age: 58.2 years) and 5,514 non-cancer patients (average age: 57.2 years) who were admitted for COVID-19 in two referral hospitals between March 2019 and August 2021. Patients were followed up until death or 31st August 2021. Multiple logistic regression models estimated the odds ratio (OR) and 95% confidence intervals (CI) of factors associated with ICU admission and intubation. The Cox regression model estimated hazard ratios (HRs) and 95% CI of factors associated with hospital and post-discharge 60-day mortalities. RESULTS: The cancer patients had higher ICU admission (OR = 1.65, 95% CI: 1.42-1.91; P-value 0.03) and intubation (OR = 3.13, 95% CI = 2.63-3.73, P-value < 0.001) than non-cancer patients. Moreover, hospital mortality was significantly higher in cancer patients than in non-cancer patients (HR = 2.12, 95% CI: 1.89-2.41, P-value < 0.001). HR for the post-discharge mortality was higher in these patients (HR = 2.79, 95% CI: 2.49-3.11, < 0.001). The hospital, comorbidities, low oxygen saturation, being on active treatment, and non-solid tumor were significantly associated with ICU admission (P-value < 0.05) in cancer patients, while only low oxygen saturation was associated with intubation. In addition, we found that old age, females, low oxygen saturation level, active treatment, and having a metastatic tumor were associated with death due to COVID-19 (P-value < 0.05). Only lung cancer patients had a significantly higher risk of death compared to other cancer types (HR = 1.50, 95% CI: 1.06-2.10, P-value = 0.02). CONCLUSION: Cancer patients are at a higher risk of ICU admission, intubation, and death due to COVID-19 than non-cancer patients. Therefore, cancer patients who are infected with COVID-19 require intensive care in the hospital and active monitoring after their discharge from the hospital.

RESUMEN

The association between systemic scleroderma and malignancy is well-documented, but there is limited data on the relationship between morphea and malignancy. This study aims to assess the incidence and types of malignancies in morphea patients, comparing demographics, clinical characteristics, treatments, and outcomes between those with and without malignancy. We conducted a retrospective study of 204 morphea patients treated at Rabin Medical Center between 2012 and 2023. Data on demographics, clinical subtypes, comorbidities, treatments, and outcomes were collected. Patients were categorized based on malignancy status and the timing of malignancy relative to their morphea diagnosis. Among the 204 patients (154 women and 50 men, mean age 53.7 ± 20 years), 47 (23%) developed malignancies. In 29 patients (61.7%), malignancy occurred before the onset of morphea; in 23 patients (48.9%), it occurred after morphea. Five patients (10.6%) had malignancies both before and after the diagnosis of morphea. Patients with malignancy were significantly older than those without (64.7 ± 15.1 years vs. 50.3 ± 20 years, p < 0.0001). The all-cause mortality rate was higher in the malignancy group compared to those without malignancy (23.4% vs. 3.8%, p = 0.00002). Moreover, mortality was higher in patients whose malignancy occurred after morphea than in those whose malignancy preceded morphea (26% vs. 17.2%). The most common post-morphea malignancies in our cohort included non-melanoma skin cancer, cervical cancer, breast cancer, stomach cancer, and lung cancer. The most common pre-morphea malignancies included breast cancer, non-melanoma skin cancer, colon cancer, prostate cancer, and testicular cancer. This study suggests potential associations between morphea and malignancies, influenced by patient age, sequence of diagnosis, and treatment regimens. Further control studies are needed to explore these relationships more definitively.

RESUMEN

The early detection of tumors is one of the key factors in increasing overall survival in cancer patients. A wide range of cancers still do not have a system of early diagnosis; therefore, the development of new non-invasive tools in this line is essential. Accordingly, the objective of our work was to develop a non-invasive screening method for the early detection of various carcinomas in plasma using a panel that combines two markers using RT-qPCR. A retrospective case-control study was conducted to develop a cancer screening test based on the detection of stromal and epithelial biomarkers (COL1A2 and KRT19) in plasma. The expression of biomarkers was evaluated using multiplex quantitative PCR applied to 47 cases with non-metastatic tumors and 13 control participants. For both biomarkers, a cut-off value was stablished using Youden's J index through ROC curve analysis and areas under the curve (AUC) were calculated. The plasma mRNA expression level of both biomarkers was significantly higher in diseased versus healthy patients. Moreover, ROC curve analysis showed an AUC value of 0.897 for the combined model. This model also resulted in a cutoff value of 0.664, as well as a sensitivity of 83% and a specificity of 84.6%. These results suggest that the plasma expression levels of COL1A2 and KRT19 could a have potential role in detecting various types of cancer at the early stages. The combined analysis of both stromal and epithelial biomarkers would provide a non-invasive screening method that would allow us to differentiate patients with an active neoplastic process.

RESUMEN

64Cu is gaining recognition not only for its diagnostic capabilities in nuclear medical imaging but also for its therapeutic and theranostic potential. The simultaneous ß- and Auger emissions of 64Cu can be utilized to induce a therapeutic effect on cancerous lesions. The finding of the exceptional biodistribution characteristics of the radionuclide 64Cu, when administered as basic copper ions, has highlighted its potential therapeutic application in cancer treatment. Preclinical and clinical research on the effectiveness of [64Cu]CuCl2 as a theranostic radiopharmaceutical has commenced only in the past decade. Current clinical studies are increasingly demonstrating the high specificity and uptake of [64Cu]Cu2+ by malignant tissues during early cancer progression, indicating its potential for early cancer diagnosis across various organs. This short review aims to present the latest preclinical studies involving [64Cu]CuCl2, offering valuable insights for researchers planning new in vitro and in vivo studies to explore the theranostic potential of [64Cu]Cu2+.

RESUMEN

AIM: To assess diagnostic and prognostic value of regulator of calcineurin 3 (RCAN3) in various malignancies. METHODS: RCAN3 expression levels were assessed across pan-cancer data sets including various molecular and immune subtypes. Receiver operating characteristic (ROC) and Kaplan-Meier curves were employed to determine the diagnostic and prognostic value of RCAN3 in pan-cancer, respectively. Enrichment analyses were used to identify RCAN3-associated terms and pathways. A special focus was placed on cervical squamous cell carcinoma and endocervical adenocarcinoma cervical cancer (CESC); we assessed the prognostic value of RCAN expression within distinct clinical subgroups and its effect on m6A modifications and immune infiltration. RESULTS: RCAN3 expression varied not only in different cancer types but also in different molecular and immune subtypes of cancers. RCAN3 displayed high accuracy in diagnosing and predicting cancers, and RCAN3 expression level was associated with the prognosis of certain cancers. CESC patients with a high RCAN3 level had a worse overall survival, disease-specific survival, and progression-free interval. RCAN3 expression was related to multiple m6A modifier genes and immune cells. CONCLUSION: In general, RCAN3 can serve as a novel biomarker for the diagnosis and prognosis in pan-cancer, especially in CESC. It may represent a promising molecular target for developing new treatments. However, our analysis is limited to bioinformatic predictions, and further biological experiments are necessary to verify our results.
