Abstract
PURPOSE Laryngeal cancer (LC) is a common malignant tumor of the head and neck. However, the relationship between ferroptosis and LC is still unclear. The aim of this study was to identify potential ferroptosis-related biomarkers for diagnosis and prognosis in LC. METHODS We screened differentially expressed genes (DEGs) related to ferroptosis in LC from the TCGA and FerrDb database. DEGs were identified and enrichment by GO/KEGG, GSEA, GSVA analysis. PPI analysis was performed using String and Cytoscape, then hub genes were extracted. Furthermore, ROC analysis, pan-cancer analysis, gene mutation analysis, immune infiltration correlation analysis and clinical correlation analysis of hub genes were performed. RESULTS A total of 59 DEGs were screened, which were more significantly enriched in biological processes and involved in HIF-1 signaling pathway, serotonergic synapse and ferroptosis. A total of 29 significant gene set pathways of LC data were performed by GSEA analysis. The GSVA analysis obtained 53 significant differential gene set pathways. The top 20 genes were identified by PPI. ROC curves revealed four of the top20 genes had a good performance, which were CA9 (AUC = 0.930), MAPK3 (AUC = 0.915), MUC1 (AUC = 0.945), and NOX4 (AUC = 0.933). Subsequent analysis found that CDKN2A has the highest mutation frequency in the top 20 gene, and IFNG had a significant correlation with age, tumor stage, degree of tumor differentiation and lymphatic clearance surgery. CONCLUSION Our study identified key genes closely related to ferroptosis in LC, which still need more studies to explore the mechanisms involved and may become effective clinical diagnostic and prognostic biomarkers.

Abstract
Mucus is a hydrogel that constitutes the first innate defense in all mammals. The main organic component of mucus, gel-forming mucins, forms a complex network through both reversible and irreversible interactions that drive mucus gel formation. Significant advances in the understanding of irreversible gel-forming mucins assembly have been made using recombinant protein approaches. However, little is known about the reversible interactions that may finely modulate mucus viscoelasticity, which can be characterized using rheology. This approach can be used to investigate both the nature of gel-forming mucins interactions and factors that influence hydrogel formation. This knowledge is directly relevant to the development of new drugs to modulate mucus viscoelasticity and to restore normal mucus functions in diseases such as in cystic fibrosis. The aim of the present review is to summarize the current knowledge about the relationship between the mucus protein matrix and its functions, with emphasis on mucus viscoelasticity.

Abstract
Background: Mucins are high-molecular-weight glycoproteins with a high O-linked carbohydrate content, which are synthesized by many secretory epithelial cells as membrane-bound and/or secreted products. Mucin-1 (MUC1) is a transmembrane mucin that protects and lubricates the mucous membranes of the human body and involves itself in various cellular functions such as growth, differentiation and signaling. An aberrant expression of MUC1 has been demonstrated in various human cancers. Many studies on MUC1 expression have been conducted on a variety of neoplastic lesions other than head-and-neck region. In this study, an attempt has been made to evaluate the MUC1 immunoexpression in oral squamous cell carcinoma (OSCC) and normal oral mucosa (NOM). Aims: This study aims to compare and correlate the immunoexpression of MUC1 in NOM and OSCC using immunohistochemical technique. Settings and Design: Thirty patients of OSCC formed the study group and thirty patients were included in the control group (NOM). Formalin-fixed paraffin wax blocks were prepared from the tissue samples obtained. Materials and Methods: Immunohistochemistry (IHC) for MUC1 was performed, and the overall percentage of positive cells along with distribution and localization of immunoexpression was studied. Statistical Analysis: Pearson's Chi-square test was used. P <0.05 was considered to be statistically significant. Results: In OSCC study group, MUC1-positive immunoreaction was observed in 21 (70%) cases out of 30. All the samples in control group were negative for MUC1 immunoexpression. The immunohistochemical expression of MUC1 in OSCC group was statistically significant when compared with normal control group, as P < 0.05 (Pearson's Chi-square). Conclusions: MUC1 is a reliable biomarker for the diagnosis of OSCC, but further studies are required to prove its role in prognosis.

Abstract
BACKGROUND Mucins alteration in glycosylation is associated with the development and progression of malignant diseases. Therefore, mucins are used as valuable markers to distinguish normal and disease conditions. Many studies on MUC1 expression have been conducted on variety of neoplastic lesions other than head and neck region. None of the study has made an attempt to show its significance in potentially malignant disorders (PMDs) and oral squamous cell carcinoma (OSCC). Hence, ours is one of the pioneer studies done to assess and evaluate the same. AIMS This study aims to compare and correlate the expression of MUC1 mucin protein in normal oral mucosa (NOM), PMD's and OSCC by immunohistochemical method. MATERIALS AND METHODS Institutional study, archived tissue sections of OSCC (n = 20), PMD's (n = 20) and NOM (n = 20) were immunostained for MUC1 mucin and percentage of positive cells evaluated. Results obtained were statistically analyzed using Kruskal-Wallis test, Mann-Whitney test and Student's t-test. RESULTS The mean MUC1 mucin positive cells in the study groups were as follows, 40% in OSCC, 28% in PMD's and 0.75% in NOM. Higher mean immunohistochemical score was observed in OSCC group followed by PMD's group and NOM group. The difference in immunohistochemical score among the groups was found to be statistically significant (P < 0.001). CONCLUSION The result of the current study suggests that determination of MUC1 mucin expression may be a parameter in the diagnosis of malignant behavior of PMD's to OSCC. MUC1 mucin expression may be a useful diagnostic marker for prediction of the invasive/metastatic potential of OSCC.

Abstract
OBJECTIVE: Mucins are high-molecular-weight glycoproteins present at the outer surface of mammalian cells. The objective of this study was to examine the expression of mucin (MUC) genes 3, 4, 5AC, 5B, 6, and 7 in early and late laryngeal squamous cancer using the in situ hybridization technique. STUDY DESIGN: Retrospective analysis of pathological archive specimens. RESULTS: While MUC 3 and 7 are expressed in a small proportion of early cancers, MUC 5AC, 5B, and 6 are not expressed in laryngeal squamous cancer. MUC 4 was expressed in 13 of the 30 patients. Ten patients and 3 patients with stage 1 and stage 4 disease respectively expressed MUC 4 gene (Fisher's exact, P = 0.02). MUC 4-positive patients had a definite trend towards better survival (log rank test, P = 0.05). In the presence of tumor stage and comorbidity grade, Cox's proportional hazards model failed to statistically confirm the survival advantage provided by MUC 4 gene expression. CONCLUSION: There is a survival advantage for patients with advanced-stage nonmetastatic cancer when the MUC 4 gene is expressed.AIMS: To study the expression of mucin (MUC) genes 3, 4, 5AC, 5B, 6, and 7 in early and advanced squamous cell cancer of the larynx; to attempt to correlate changes in gene expression with tumor stage by studying stage I and stage IV (AJCC, 1988) tumors.

Abstract
Activation of an aberrant glycosylation pathway in cancer cells can lead to expression of the onco-foetal sialyl-Tn (sTn) antigen. STn is a truncated O-glycan containing a sialic acid α-2,6 linked to GalNAc α-O-Ser/Thr and is associated with an adverse outcome and poor prognosis in cancer patients. The biosynthesis of the sTn antigen has been linked to the expression of the sialytransferase ST6GalNAc1, and also to mutations in and loss of heterozygosity of the COSMC gene. sTn neo- or over-expression occurs in many types of epithelial cancer including gastric, colon, breast, lung, oesophageal, prostate and endometrial cancer. sTn is believed to be carried by a variety of glycoproteins and may influence protein function and be involved in tumour development. This review discusses how the role of sTn in cancer development and tumour cell invasiveness might be organ specific and occur through different mechanisms depending on each cancer type or subtype. As the sTn-antigen is expressed early in carcinogenesis targeting sTn in cancer may enable the targeting of tumours from the earliest stage.

Abstract
Little is known on the expression of the tumour-associated carbohydrate antigen sialyl-Tn (STn), in bladder cancer. We report here that 75% of the high-grade bladder tumours, presenting elevated proliferation rates and high risk of recurrence/progression expressed STn. However, it was mainly found in non-proliferative areas of the tumour, namely in cells invading the basal and muscle layers. STn was also found in tumour-adjacent mucosa, which suggests its dependence on a field effect of the tumour. Furthermore, it was not expressed by the normal urothelium, demonstrating the cancer-specific nature of this antigen. STn expression correlated with that of sialyltransferase ST6GalNAc.I, its major biosynthetic enzyme. The stable expression of ST6GalNAc.I in the bladder cancer cell line MCR induced STn expression and a concomitant increase of cell motility and invasive capability. Altogether, these results indicate for the first time a link between STn expression and malignancy in bladder cancer. Hence, therapies targeting STn may constitute new treatment approaches for these tumours.

Abstract
Sialyl-Tn antigen (STn) is a short O-glycan containing a sialic acid residue α2,6-linked to GalNAcα-O-Ser/Thr. The biosynthesis of STn is mediated by a specific sialyltransferase termed ST6GalNAc I, which competes with O-glycans elongating glycosyltransferases and prevents cancer cells from exhibiting longer O-glycans. While weakly expressed by fetal and normal adult tissues, STn is expressed by more than 80% of human carcinomas and in all cases, STn detection is associated with adverse outcome and decreased overall survival for the patients. Because of its pan-carcinoma expression associated with an adverse outcome, an anti-cancer vaccine, named Theratope, has been designed towards the STn epitope. In spite of the great enthusiasm around this immunotherapy, Theratope failed on Phase III clinical trial. However, in lieu of missing this target, one should consider to revise the Theratope design and the actual facts. In this review, we highlight the many lessons that can be learned from this failure from the immunological standpoint, as well as from the drug design and formulation and patient selection. Moreover, an irrefutable knowledge is arising from novel immunotherapies targeting other carbohydrate antigens and STn carrier proteins, such as MUC1, that will warrantee the future development of more successful anti-STn immunotherapy strategies.

Abstract
Mucins are high molecular weight glycoproteins that play important roles in carcinogenesis and tumor invasion. Our immunohistochemical studies demonstrated that MUC1 or MUC4 expression is related to the aggressive behavior and poor outcome of human neoplasms. MUC2 is expressed in indolent pancreatobiliary neoplasms, but these tumors sometimes show invasive growth with MUC1 expression in invasive areas. MUC5AC shows de novo high expression in many types of precancerous lesions of pancreatobiliary cancers and is an effective marker for early detection of the neoplasms. The combination of MUC1, MUC2, MUC4 and MUC5AC expression may be useful for early detection and evaluation of the potential for malignancy of pancreatobiliary neoplasms. Regarding the mechanism of mucin expression, we have recently reported that expression of the mucin genes is regulated epigenetically in cancer cell lines, using quantitative MassARRAY analysis, methylation-specific polymerase chain reaction analysis and chromatin immunoprecipitation analysis, with confirmation by the treatment with 5-aza-2'-deoxycytidine and trichostatin A. We have also developed a monoclonal antibody against the MUC1 cytoplasmic tail domain, which has many biological roles. Based on all of the above findings, we suggest that translational research into mucin gene expression mechanisms, including epigenetics, may provide new tools for early and accurate detection of human neoplasms.

Abstract
Mucins are the dominant component in the protective mucus layer on mucosal surfaces including the larynx. Hence, they are part of the first line of defence against external stimuli including effect of smoking in the larynx. We asked whether existing published evidence supported the hypothesis that alteration in mucins expression/production is related to the laryngeal neoplastic process. The objective of this study is to review published evidence for mucins having an important role in normal laryngeal physiology and the development of laryngeal squamous cell carcinoma (SCC). We aimed to review all available literature on mucins in the larynx in order to develop hypotheses to be tested by future research. Thereby, new potential means of prevention and treatment of laryngeal cancer may be developed. A systematic search of all published literature was conducted. Systematic searches were done in the following databases: AMED, BNI, EMBASE, HMIC, MEDLINE, PsycINFO, CINAHL and HEALTH BUSINESS ELITE from their respective inception up to 11 February 2011. The following keywords were used in combination: mucin, larynx and squamous cell carcinoma. Altogether, 53 studies were identified; 43 studies were excluded following screening of the titles and abstracts. Full text manuscripts for ten studies were obtained for detailed evaluation and five studies were included in this review. No single study fulfilled all relevant criteria. Based on the included studies, we now know that MUC1 is definitely expressed in SCC larynx. However, there is no definitive evidence to suggest that MUC1 and MUC2 are aberrantly expressed in SCC larynx as compared to normal larynx. Further studies using the best available detection technique to detect MUC1, MUC2 and other possible relevant mucins i.e., MUC4 on adequate numbers of normal and SCC specimens are needed to confirm the findings of this review.

Abstract
BACKGROUND In head and neck squamous cell carcinoma (HNSCC), tumor markers may be helpful to evaluate prognosis accurately as well as to improve therapy selection. Detection of human MUC1 has been widely employed for the evaluation of carcinoma patients. This article aims to study MUC1, Tn, sTn, and Lewis antigenic expression in primary HNSCC, lymph node metastasis, and local recurrences. METHODS We used immunohistochemistry, tissue homogenization and differential centrifugation, isopycnic density gradient centrifugation, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and Western blot. RESULTS In primary tumors, MUC1 was detected in 80.0% of the samples; sLewis x in 23.2%, Lewis x in 45.6%, and Lewis y in 40.8%. Tn and sTn were found in 4.0% and 6.4% of samples, respectively. In metastatic lymph nodes, MUC1 showed a similar positive reaction as in primary tumors. Lewis y was detected in 20% lymph nodes whereas Lewis x, sLewis x, Tn, and sTn did not show differences. Some recurrences expressed MUC1 and only a few Lewis antigens, whereas Tn and sTn were not detected. CONCLUSION In primary HNSCC and metastatic nodes, a high expression of MUC1 and Lewis antigens was detected that diminished in local recurrences. We also found that differentiated tumors mainly expressed a linear pattern of MUC1CT and Lewis x.

Abstract
An immunohistochemical analysis was employed to determine the expression of carbohydrate antigens associated to mucins in normal epithelia. Tissue samples were obtained as biopsies from normal breast (18), colon (35) and oral cavity mucosa (8). The following carbohydrate epitopes were studied: sialyl-Lewis x, Lewis x, Lewis y, Tn hapten, sialyl-Tn and Thomsen-Friedenreich antigen. Mucins were also studied employing antibodies against MUC1, MUC2, MUC4, MUC5AC, MUC6 and also normal colonic glycolipid. Statistical analysis was performed and Kendall correlations were obtained. Lewis x showed an apical pattern mainly at plasma membrane, although cytoplasmic staining was also found in most samples. TF, Tn and sTn haptens were detected in few specimens, while sLewis x was found in oral mucosa and breast tissue. Also, normal breast expressed MUC1 at a high percentage, whereas MUC4 was observed in a small number of samples. Colon specimens mainly expressed MUC2 and MUC1, while most oral mucosa samples expressed MUC4 and MUC1. A positive correlation between MUC1VNTR and TF epitope (r=0.396) was found in breast samples, while in colon specimens MUC2 and colonic glycolipid versus Lewis x were statistically significantly correlated (r=0.28 and r=0.29, respectively). As a conclusion, a defined carbohydrate epitope expression is not exclusive of normal tissue or a determined localization, and it is possible to assume that different glycoproteins and glycolipids may be carriers of carbohydrate antigens depending on the tissue localization considered.

Abstract
To investigate the influence of sialic acid removal on MUC1 peptidic and carbohydrate epitope reactivity in head and neck squamous cell carcinoma (HNSCC), tumor samples belonging to 24 HNSCC patients were studied by standard immunohistochemistry (IHC) with and without desialylation with 0.1 U/ml neuraminidase. From each tumor sample, subcellular fractions were obtained and analyzed by SDS-PAGE and Western blotting (WB). Three monoclonal antibodies (MAbs) were used: C595 MAb directed to MUC1 protein core, an anti-Tn hapten MAb, and an anti-sTn hapten MAb; a comparative analysis between desialylated and sialylated samples was performed. By IHC without neuraminidase treatment, 19 of 24 samples reacted with anti-MUC1 peptidic epitope, while Tn hapten was not detected and sTn was found in 1 of 24 cases. Desialylation increased either the number of reacting cells or the intensity of the reaction with C595 and anti-Tn MAbs, and some negative samples became positive. On the other hand, sTn expression decreased with desialylation. By WB, several bands from >200 to 25 kDa were found; desialylation increased high-molecular-weight bands, diminishing the detection of low-molecular-weight ones. The use of desialylation is a suitable treatment that contributes to the exposure of MUC1-associated epitopes, which may be related to the spreading of HNSCC.

Abstract
UNLABELLED An immunological analysis to study MUC1 mucin core protein and carbohydrate associated antigens as tissue tumor markers in head and neck carcinoma was performed. Twenty nine patients with the following tumor localizations were included: tongue (n=10), larynx (n=8), oral cavity (n=4), maxillary sinus (n=3), tonsillar ring (n=3) and pharynx (n=1); seven samples of epithelium obtained from normal organs at the same localizations were studied as controls. Immunohistochemical analysis was performed following standard procedures and reaction was graded according to staining intensity and distribution. From each tissue section, membrane, cytoplasmic and nuclear moieties were obtained by differential centrifugation with subsequent fractionation by density gradient centrifugation (6M guanidium chloride-CsCl); subcellular moieties and CsCl derived fractions were analyzed by immunoblotting. Monoclonal antibodies (MAbs) reacting with the core protein of MUCI (C595) and associated carbohydrate antigens were: Tn, 83D4 MAb; Lewis y antigen (Le y), C14 MAb; Lewis x antigen (Le x), KM380 MAb and sialyl Lewis x (sLe x), KM93 MAb. Statistical analysis was undertaken by Spearman rank correlation. In tumor samples, the immunohistochemical identification of MUCl core protein and associated antigens was extended; differences were found in the pattern and intensity of expression; results were corroborated by immunoblotting although in a few samples there was not coincidence between both methods. Localization, tumor mass or node involvement did not show significant differences for any of the antigens studied. CONCLUSIONS 1) head and neck carcinoma expressed MUCI and associated carbohydrate antigens in high levels; 2) no relationship between antigenic expression and tumor status was found.

Abstract
The female uterine cervix has 2 characteristic populations of epithelial cells: the endocervix is composed by mucus-secreting cells that express several mucin genes, and the exocervix has a typical stratified squamous epithelium and does not express secreted mucins. Among human mucin genes, the MUC4 sequence has a transmembrane domain, and its molecular structure suggests that it has a protective role and also may be implicated in intracellular signalling. The aim of this study is to analyze whether changes in the expression of MUC4 can be detected associated with the squamous dysplastic transformation of exocervical epithelium. MUC4 expression has been analyzed by immunohistochemistry, Western blotting, and in situ hybridization. Using immunohistochemical techniques, MUC4 is found in normal endocervix (n = 11) and is absent or only focally detected in the normal stratified cervical epithelium (n = 18). In samples from squamous metaplasia (n = 9), MUC4 is variably expressed (10% to 50% positive cells), whereas MUC4 is strongly detected in dysplastic cervical epithelia. The greatest number of positive cells is found in samples with moderate and severe dysplasia in which MUC4 is detected in 100% of the analyzed samples (n = 16). These results have been confirmed by Western blotting and by detection of MUC4 transcripts using in situ hybridization. The present data suggest that MUC4 is activated during the process of squamous dysplastic transformation and may be used as a marker for this pathologic process.

Abstract
The aim of this study was to examine the expression of MUC1 and MUC2 glycoproteins in laryngeal cancer and to determine if mucin expression is related to prognosis. The study included laryngeal specimens from 57 patients comprising of 36 laryngeal carcinomas and 21 normal controls. High MUC1 expression was found in both carcinomas and normal control groups (P = 0.689, Fisher's exact test). High levels of MUC2 expression were only detected in carcinomas versus controls (P = 0.009, Fisher's exact test). Using multivariate analysis neither MUC1 nor MUC2 expression significantly related to survival. MUC1 expression however, did correlate with T stage. Advanced T stage was associated with prognosis (P = 0.001).

Abstract
The purpose of this study was to determine whether mucin expression is altered in laryngeal cancer. MUC1 and MUC2 mucin expression was examined in biopsy specimens from 80 patients that comprised 23 laryngeal dysplasias, 36 laryngeal carcinomas, and 21 normal larynx control specimens. High MUC1 expression was found in all 3 groups (P = 0.689, Fisher exact test). However, significantly higher levels of MUC2 expression were detected in carcinomas compared with dysplasias and control specimens (P = 0.009, Fisher exact test). Altered MUC2 expression may be an important step in carcinogenesis in laryngeal cancer.

Abstract
Serum from patients with different malignancies contain an abnormal concentration of a a1-acidic-glycoprotein (AAG) and also, increased levels of AAG are associated with the presence of tumor mass. In the present report, serum levels of AAG were measured by radial immunodiffusion in squamous cell carcinoma of the head and neck (SCCHN) patients taking into account disease status parameters such as tumor localization, stage and extension of disease. Immunohistochemical methods, SDS-PAGE and Western-blotting were employed to study the expression of AAG and a carbohydrate related antigen (sialyl Lewis x) in tumor tissues and derived fractions. AAG showed abnormal levels in 7/15 oral cavity tumor patients sera, 2/5 oropharynx and 5/10 larynx tumors; increased AAG serum levels belonged to patients with disseminated disease. On the other hand, the presence of AAG and sialyl Lewis x were demonstrated in carcinoma cells and in derived fractions from tumor tissues belonging to patients with elevated AAG serum levels. In the present study, we have found elevated levels of AAG in serum samples from SCCHN patients; these neoplastic cells are capable to express AAG.

Abstract
UNLABELLED The progression from uncontrolled cell proliferation to invasion and metastasis of epithelial tumors is partially understood. Alteration of epithelial mucin expression have been described in different malignant localizations but only few attempts have been made to identify mucin expression in malignant laryngeal tumors. In the present report, results are shown of studies on the expression of mucins and carbohydrate related antigens in laryngeal cancer and on the isolation of MUC1 mucin from this tumor tissue. Malignant laryngeal specimens were processed for immunohistochemical analysis and for extranuclear membrane fractions (ENM) which were obtained by ultracentrifugation. Subsequently, ENM samples were centrifuged in density-gradient; the analysis of fractions was performed by means of SDS-PAGE and Western-blotting. The panel of monoclonal antibodies (MAbs) included anti MUC1 mucin, anti Lewis x, anti sialyl Lewis x, anti Lewis y, anti MUC-5B, anti oral mucin (gp230), anti Tn hapten, anti p53 and anti cytokeratins. By immunohistochemistry, it was possible to detect MUC1 mucin, Lewis x and Lewis y showing strong reactions while sialyl-Lewis x and Tn antigen only reacted weakly in a few cells; cytokeratins were detected in all samples. In ENM derived fractions obtained by CsCl centrifugation, MUC1 was demonstrated by Western blotting. CONCLUSIONS (1) laryngeal cancer antigenic expression comprises mostly MUC1 mucin, Lewis x, Lewis y as well as Tn antigen and (2) the methodology here employed is useful to isolate MUC1 from tumor samples.

Abstract
BACKGROUND MUC1 mucin is a transmembrane, mucin-like glycoprotein encoded by the MUC1 gene. Although MUC1 expression has been identified in a variety of neoplastic tissues, to the authors' knowledge, few studies have examined MUC1 expression in premalignant and malignant oral lesions. METHODS A total of 36 specimens of oral epithelial dysplasia, 12 carcinoma in situ (CIS) specimens and 77 specimens of oral squamous cell carcinoma (OSCC), were examined by both light and electron microscopy using immunohistochemical staining of MUC1 mucin. Relations between staining patterns and clinicopathologic findings also were examined. RESULTS Distinct membrane MUC1 mucin staining patterns were identified in epithelial dysplasia (33.0%), CIS (50.0%), and OSCC (59.7%) cases. A predominantly cytoplasmic staining pattern was detected in epithelial dysplasia (5.6%), CIS (41.7%), and OSCC (32.5%) cases. Significant positive correlations were found between MUC1 mucin membranous immunoreactivity and disease progression from epithelial dysplasia to OSCC (P < 0.01), mode of tumor invasion (P < 0.02), and lymph node metastasis (P < 0.01). Furthermore, the malignant transformation of oral epithelium, tumor invasion, and tumor metastasis were associated with higher MUC1 mucin expression in the cytoplasm (P < 0.01). In addition to the usual cell surface expression, cytoplasmic expression of MUC1 mucin was confirmed by colloidal gold labeling with transmission electron microscopy. CONCLUSIONS The results of the current study suggest that determination of MUC1 mucin expression may be a parameter in the diagnosis of premalignant and malignant lesions arising in the oral cavity and that this expression may affect the malignant behavior of OSCC. MUC1 mucin expression may be a useful diagnostic marker for prediction of the invasive/metastatic potential of OSCC.

Abstract
Sarcomatoid carcinoma of the pancreas is an uncommon neoplasm. The immunohistochemical characteristics of this unique type of pancreatic tumor were studied. Histologically, there was diffuse proliferation of atypical spindle cells that had hyperchromatic, short, spindle-shaped nuclei and pale cytoplasm. A few tiny foci of small tubular structures were seen in connection with the atypical spindle-shaped cells. Immunohistochemical examination showed that the spindle cells were positive for epithelial cell markers (cytokeratin AE3, cytokeratin AE1, epithelial membrane antigen) and DF3 (MUC1 apomucin-related antigen (ARA)), and were negative for markers such as vimentin, desmin, neuron-specific enolase, and myoglobin. DF3 antigen is known to be expressed in invasive ductal carcinoma of the pancreas and liver, as well as of the breast. Other MUC1-ARA (MY.1E12, MUC1 glycoprotein, HMFG-1, HMFG-2) and anti-CA19-9 were also detected in the present case. Thus, this tumor was diagnosed as anaplastic carcinoma (sarcomatoid carcinoma).
