Diagnostic Challenges during Inflammation and Cancer: Current Biomarkers and Future Perspectives in Navigating through the Minefield of Reactive versus Dysplastic and Cancerous Lesions in the Digestive System. Int J Mol Sci 2024; 25:1251. [PMID: 38279253 PMCID: PMC10816510 DOI: 10.3390/ijms25021251] [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: 12/19/2023] [Revised: 01/12/2024] [Accepted: 01/16/2024] [Indexed: 01/28/2024] Open
Abstract
In the setting of pronounced inflammation, changes in the epithelium may overlap with neoplasia, often rendering it impossible to establish a diagnosis with certainty in daily clinical practice. Here, we discuss the underlying molecular mechanisms driving tissue response during persistent inflammatory signaling along with the potential association with cancer in the gastrointestinal tract, pancreas, extrahepatic bile ducts, and liver. We highlight the histopathological challenges encountered in the diagnosis of chronic inflammation in routine practice and pinpoint tissue-based biomarkers that could complement morphology to differentiate reactive from dysplastic or cancerous lesions. We refer to the advantages and limitations of existing biomarkers employing immunohistochemistry and point to promising new markers, including the generation of novel antibodies targeting mutant proteins, miRNAs, and array assays. Advancements in experimental models, including mouse and 3D models, have improved our understanding of tissue response. The integration of digital pathology along with artificial intelligence may also complement routine visual inspections. Navigating through tissue responses in various chronic inflammatory contexts will help us develop novel and reliable biomarkers that will improve diagnostic decisions and ultimately patient treatment.

High mobility group A protein-2 as a tumor cancer diagnostic and prognostic marker: a systematic review and meta-analysis. Eur J Cancer Prev 2020; 29:565-581. [PMID: 32898013 DOI: 10.1097/cej.0000000000000602] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
High mobility group A protein-2 (HMGA2) is an architectural transcription factor that binds to the A/T-rich DNA minor groove and is responsible for regulating transcriptional activity of multiple genes indirectly through chromatin change and assembling enhanceosome. HMGA2 is overexpressed in multiple tumor types, suggesting its involvement in cancer initiation and progression, thus, making it an ideal candidate for cancer diagnostic and prognostic. We performed a systematic review to examine the role of HMGA2 as a universal tumor cancer diagnostic and prognostic marker. We used Reporting Recommendations for Tumor Marker Prognostic Studies to systematically search OvidMedline, PubMed, and the Cochrane Library for English language studies, published between 1995 and June 2019. Meta-analysis provided pooled risk estimates and their 95% confidence intervals (CIs) for an association between overall survival and recurrence of cancers for studies with available estimates. We identified 42 eligible studies with a total of 5123 tumor samples in 15 types of cancer. The pooled percentage of HMGA2 gene expression in tumor samples was 65.14%. Meta-analysis showed that cancer patients with HMGA2 positive have significantly reduced survival, compared to patients without HMGA2 gene [pooled-hazard ratio (HR) = 1.85, 95% CI 1.48-2.22]. There was a positive association between cancer patients with HMGA2 overexpression and cancer recurrence though this association did not reach significance (pooled-HR = 1.44, 95% CI 0.80-2.07). Overexpression of HMGA2 was found in 15 types of cancer. There was an association between HMGA2 overexpression with reduced survival of cancer patients. HMGA2 is thus considered a promising universal tumor marker for prognostics.

High-mobility group AT-hook 2: an independent marker of poor prognosis in intrahepatic cholangiocarcinoma. Hum Pathol 2014; 45:2334-40. [PMID: 25245603 DOI: 10.1016/j.humpath.2014.04.026] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2013] [Revised: 03/25/2014] [Accepted: 04/02/2014] [Indexed: 12/24/2022]
Abstract
High-mobility group AT-hook 2 (HMGA2) regulates cell growth, differentiation, apoptosis, and neoplastic transformation. Previous studies have shown that malignant tumors expressing HMGA2, such as gastric, lung, and colorectal carcinomas, usually have a poor prognosis. HMGA2 expression and its clinical significance in intrahepatic cholangiocarcinomas have not been studied. We identified 55 intrahepatic cholangiocarcinomas resected at our institution from 1994 to 2003. Hematoxylin-eosin-stained slides were reviewed, and histopathologic characteristics were recorded, including mitotic count, tumor grade, vascular and perineural invasion, lymph node metastasis, and margin status. Using immunohistochemical stains, we examined expression of HMGA2, p53, p16, Kit, α-fetoprotein, and Ki-67, and we analyzed the correlation of survival with clinicopathological characteristics and immunohistochemical findings. Positive staining for HMGA2, p53, p16, Kit, α-fetoprotein, and Ki-67 was seen in 18 (33%), 37 (69%), 26 (47%), 21 (38%), 2 (4%), and 34 (63%) tumors, respectively. HMGA2 expression correlated positively with p53 expression (P = .02; ρ = 0.32) and negatively with p16 expression (P = .04; ρ = -0.28). Univariate analysis showed that HMGA2 expression and lymph node metastasis were associated with shorter patient survival and were independent indicators of poor survival (P = .02 and P = .03, respectively). Tumorigenic effects of HMGA2 in intrahepatic cholangiocarcinoma may partly reflect its ability to negatively regulate expression of p16 tumor suppressors and to be associated with p53 abnormalities.

Abstract
BACKGROUND Metastasis-associated in colon cancer-1 (MACC1), a newly identified regulator of HGF-MET signaling, may participate into the key steps of sporadic colorectal adenocarcinoma development. Given there are many pathogenetic distinctions between colitis-associated colorectal cancer (CAC) and sporadic colorectal adenocarcinomas, the potential roles of MACC1 in CAC carcinogenesis remain unknown. For the first time, we evaluated the expressions of MACC1 and MET in IBD-associated colitis, dysplasia, and adenocarcinoma. METHODS Expression was investigated by immunohistochemistry in tissue microarrays consisting of 13 normal colon, 11 active colitis, 9 dysplasia, 51 conventional CAC, 5 mucinous adenocarcinoma, and 1 signet ring cell adenocarcinoma specimens. The expression level of MACC1 or MET was evaluated with H-score system. RESULTS MACC1 expression was significantly higher in IBD-associated dysplasia than that in corresponding inflammatory or normal colonic tissue, and its level was further elevated from dysplasia to conventional CAC. Higher MACC1 expression was seen in a patient with CAC who had multifocal dysplasia or synchronous carcinoma. MACC1 overexpression (H-score >100) was seen in 67% of conventional CAC but in 0% of dysplasia and 0% of inflammation or normal colon. There was no difference of MACC1 expression found among well, moderately and poorly differentiated CAC. MET expressions in inflammation, dysplasia, and conventional CAC were statistically similar. No parallel expression of MACC1 and MET was detected in this study. MACC1 and MET expression was not increased in mucinous or signet ring cell carcinoma, 2 distinct variants of CAC. CONCLUSIONS Stepwise increase of MACC1 expression from IBD-associated colitis to dysplasia to adenocarcinoma suggests that MACC1 is strongly associated with conventional CAC tumorigenesis in a manner independent of MET. MACC1 may serve as a potential marker for early diagnosis of conventional CAC.

Abstract
OBJECTIVES To investigate metastasis associated in colon cancer 1 (MACC1) and MET expression in colorectal adenoma, Tis, early-stage invasive (T1 and T2), and advanced adenocarcinoma with liver metastasis using immunohistochemistry. METHODS Ninety-three paraffin-embedded colorectal tumor specimens were immunohistochemically analyzed for MACC1 and MET protein expression. RESULTS MACC1 expression was upregulated in the transition from adenoma to Tis; its expression was further elevated during tumor progression from Tis to early invasive carcinoma. MET expression was constant from adenoma to Tis and to T1 but significantly increased as tumor progression to T2. Both MACC1 and MET expression were enhanced in advanced carcinoma with liver metastasis. CONCLUSIONS Stepwise elevation of MACC1 expression in key points of colorectal cancer development suggests that MACC1 may contribute to cancer initiation and early invasive growth. High expression of both MACC1 and MET may relate to distant metastasis.
