Abstract
Head and neck cancer (HNC), the seventh most common form of cancer worldwide, is a group of epithelial malignancies affecting sites in the upper aerodigestive tract. The 5-year overall survival for patients with HNC has stayed around 40–50% for decades, with mortality being attributable mainly to late diagnosis and recurrence. Recently, non-coding RNAs, including tRNA halves, YRNA fragments, microRNAs (miRNAs), and long non-coding RNAs (lncRNAs), have been identified in the blood and saliva of patients diagnosed with HNC. These observations have recently fueled the study of their potential use in early detection, diagnosis, and risk assessment. The present review focuses on recent insights and the potential impact that circulating non-coding RNA evaluation may have on clinical decision-making in the management of HNC.

Optimized Cutoff Value of Serum Squamous Cell Carcinoma Antigen Concentration Accurately Predicts Recurrence After Curative Resection of Squamous Cell Carcinoma of the Esophagus. Ann Surg Oncol 2019; 27:1233-1240.

Abstract
BACKGROUND Squamous cell carcinoma antigen (SCC-Ag) and carcinoembryonic antigen (CEA) are widely used in clinical practice to predict the prognosis of patients with esophageal squamous cell carcinoma (ESCC). However, their predictive values for prognosis are controversial. This study determined optimal cutoff values of serum SCC-Ag and CEA concentrations for predicting postoperative recurrence of ESCC, which enabled selection of high-risk patients. METHODS The study retrospectively analyzed 427 patients who underwent curative resection for ESCC. The optimal cutoff values of preoperative SCC-Ag and CEA concentrations for predicting postoperative recurrence were determined using combined analysis of hazard ratios and sensitivities for recurrence. Using the optimal cutoff value, the study evaluated survival, recurrence patterns, and temporal changes in marker concentrations. RESULTS The preoperative SCC-Ag concentration of 1.1 ng/ml was the optimal cutoff value for predicting postoperative recurrence, whereas precise cutoff values could not be determined for preoperative CEA concentrations. High preoperative SCC-Ag concentrations (> 1.1 ng/ml), which were significantly associated with more aggressive tumor phenotypes and shorter disease-free survival, were identified as an independent prognostic factor in the multivariable analysis. High preoperative SCC-Ag concentrations were significantly associated with greater prevalence of lung/pleura and local recurrences. Normalization of serum SCC-Ag concentrations after neoadjuvant treatment or esophagectomy was not associated with a decreased risk of postoperative recurrence. CONCLUSIONS The optimal cutoff value of preoperative SCC-Ag concentrations that predicted recurrence of ESCC was 1.1 ng/ml, illuminating the utility of serum SCC-Ag concentrations as an easily measurable tool for selecting a perioperative management strategy.

Early diagnosis of radiotherapy failure for patients with head and neck cancer: the role of biochemical markers. TUMORI JOURNAL 2018; 104:273-279.

Abstract
PURPOSE There is a lack of effective diagnostic tools for early assessment of radiotherapy (RT) outcome in patients with head and neck cancer (HNC). The timely diagnosis of treatment failure may facilitate use of salvage procedures to prevent disease progression. We assessed squamous cell carcinoma antigen and CYFRA 21-1 as early markers of radiotherapy failure in patients with HNC. METHODS Between January 2009 and February 2012, 185 patients (median age 59 years) with squamous cell carcinoma were treated with curative intent with RT alone or combined with chemotherapy (ChT). Markers were estimated in the serum 2 times: before RT and after completion of treatment. RESULTS The median of follow-up was 40 months. Locoregional control (LRC) was 53% and locoregional failure (LRF) was 31%. When comparing LRC and LRF, there were no significant differences between markers concentration obtained before RT. After RT, CYFRA 21-1 (p = 0.018) was significantly elevated in the LRF group. Patients with CYFRA 21-1 <1.79 ng/mL had a higher disease-free survival rate compared to patients with CYFRA 21-1 ≥1.79 ng/mL (74% vs 53%, respectively). After RT, CYFRA 21-1 was significantly related to the overall survival ratio in both univariate (p = 0.049) and multivariate analysis (p = 0.019). CONCLUSIONS CYFRA 21-1 assessed at the end of RT or ChT seems to be a prognostic marker for tumor response. A high concentration of CYFRA 21-1 after treatment increases the risk of death. CYFRA 21-1 might be suggested in the monitoring of carcinomas of HNC.

Abstract
Background We initially proposed a useful and novel prognostic model, named CCS [Combination of c-reactive protein (CRP) and squamous cell carcinoma antigen (SCC)], for predicting the postoperative survival in patients with esophageal squamous cell carcinoma (ESCC). Methods Two hundred and fifty-two patients with resectable ESCC were included in this retrospective study. A logistic regression was performed and yielded a logistic equation. The CCS was calculated by the combined CRP and SCC. The optimal cut-off value for CCS was evaluated by X-tile program. Univariate and multivariate analyses were used to evaluate the predictive factors. In addition, a novel nomogram model was also performed to predict the prognosis for patients with ESCC. Results In the current study, CCS was calculated as CRP+6.33 SCC according to the logistic equation. The optimal cut-off value was 15.8 for CCS according to the X-tile program. Kaplan-Meier analyses demonstrated that high CCS group had a significantly poor 5-year cancer-specific survival (CSS) than low CCS group (10.3% vs. 47.3%, P <0.001). According to multivariate analyses, CCS (P =0.004), but not CRP (P =0.466) or SCC (P =0.926), was an independent prognostic factor. A nomogram could be more accuracy for CSS (Harrell's c-index: 0.70). Conclusion The CCS is a usefull and independent predictive factor in patients with ESCC.

Abstract
CONCLUSIONS Serum squamous cell carcinoma antigen (SCC-Ag) level was an independent prognostic factor for survival in patients with head and neck squamous cell carcinoma (HNSCC), and the prognostic value depended on the carcinoma site. OBJECTIVES To assess the value of SCC-Ag as a prognostic indicator in patients with HNSCC and to determine the effect of primary tumor site on prognosis. METHODS We reviewed 493 patients with HNSCC between 2004 and 2012. The chi-squared test was used to assess associations between SCC-Ag levels and TNM classification. A Cox proportional hazard model was used to assess the hazard ratio of SCC-Ag at different sites for death, and it was analyzed as a continuous variable. RESULTS The median serum level of SCC-Ag was 1.1 ng/ml (range 0-20). SCC-Ag was significantly higher in patients with advanced T and N classification tumors. Primary sites in the oral cavity, in the hypopharynx, advanced T and N classification, distant metastasis, and SCC-Ag were negatively associated with survival in univariate analysis. Multivariate analysis revealed that SCC-Ag was a significant risk factor for overall survival in cancers of the oral cavity, hypopharynx, and larynx, but not in oropharyngeal cancer.

Abstract
BACKGROUND The clinical importance of serum squamous cell carcinoma antigen (SCCA) and SCCA subclasses has not been established for treating inverted papilloma (IP). The aim of this study was to clarify the clinical importance of serum SCCA and its subclasses in IP, compared with maxillary squamous cell carcinoma and inflammatory disease. METHODS Serum SCCA was measured in 22 patients with IP (IP group), 11 with maxillary squamous cell carcinoma (carcinoma group), and 22 with inflammatory disease (inflammatory group). mRNA expression of SCCA subclasses was examined using quantitative real-time polymerase chain reaction. RESULTS In the IP group, 81.8% showed elevated serum SCCA, and 90.3% with recurrent IP showed elevated SCCA. The preoperative SCCA value (mean ± SD, 3.99 ± 4.39) in the IP group was significantly higher than in the carcinoma (1.28 ± 0.88; p = 0.012) and inflammatory (0.60 ± 0.31; p < 0.001) groups. mRNA expression of SCCA1 and SCCA2 in the IP group was higher than in the carcinoma and inflammatory groups. The SCCA2/SCCA1 ratio of mRNA expression (0.11 ± 0.06) in the IP group was similar to that (0.11 ± 0.09) in the inflammatory group, although the ratio (0.20 ± 0.12) in the carcinoma group was significantly higher than in the IP and inflammatory groups. The receiver operating characteristic curve analysis for the SCCA2/SCCA1 ratio to detect carcinoma yielded an area under the curve of 0.760 (95% confidence interval, 0.626-0.894). CONCLUSION The serum level of SCCA is effective for detecting IP, including recurrent IP. In contrast, the SCCA2/SCCA1 ratio is useful for detecting squamous cell carcinoma among other sinonasal diseases.

Abstract
Squamous cell carcinoma antigen (SCCA) is overexpressed in many squamous cell cancers and SCCA‑derived peptide-specific CD8(+) cytotoxic T lymphocytes can display cytotoxicity against tumor cells. In the present study, we screened the SCCA amino acid sequence for potential HLA-A*0201-binding CD8(+) T‑cell epitopes using two predictive computational algorithms. Seven epitope candidates were selected of which SCCA(246-254)(llpneidgl), SCCA(223-231)(sledvqakv), SCCA(328‑336)(vlhkafvev) and SCCA(324‑332)(vlsgvlhka) significantly stabilized HLA-A*0201 molecules on T2 cells. Both SCCA(328‑336) and SCCA(324-332) induced CD8(+) IFN-γ(+) T‑cell responses in HLA-A*0201-positive peripheral blood mononuclear cells as assessed by intracellular cytokine staining. Consistent with this, immunization with either SCCA(328-336) or SCCA(324‑332) effectively elicited CD8(+) IFN-γ(+) T cells in HLA-A*0201 transgenic mice as visualized by IFN-γ ELISPOT assay and intracellular cytokine staining. Furthermore, CD8(+) T cells induced in vitro or in vivo by SCCA(328-336) or SCCA(324-332) demonstrated in vitro cytotoxicity against peptide-pulsed T2 cells and splenocytes, respectively. These novel SCCA‑derived CD8(+) T‑cell epitopes described, herein, may be potentially important components for diagnostic reagents and immunotherapeutic vaccines for the treatment of squamous cell carcinomas.

Abstract
The levels of squamous cell carcinoma antigen (SCC-Ag) and C-reactive protein (CRP) can be used to predict tumor invasion, lymph node metastasis, staging and survival in patients with oral cavity cancer. The present study analyzed the relationship between pre-treatment levels of SCC-Ag and CRP in relation to clinicopathological factors in patients with pharyngolaryngeal cancer (PLC) and determined whether elevated levels of CRP and SCC-Ag were associated with tumor metabolic activity via [18F] fluorodeoxyglucose positron emission tomography (FDG-PET). We retrospectively recruited one hundred and six PLC patients between June 2008 and December 2011. All patients received computed tomography (CT)/magnetic resonance imaging (MRI) and FDG-PET staging analyses, and the serum levels of SCC-Ag and CRP in these patients were measured prior to treatment. A SCC-Ag level ≥2.0 ng/ml and a CRP level ≥5.0 mg/L were significantly associated with clinical stage (P<0.001), clinical tumor status (P<0.001), and clinical nodal status (P<0.001). The elevation of both SCC-Ag and CRP levels was correlated with the standardized uptake value (SUV) max of the tumor (≥8.6 mg/L) and lymph nodes (≥5.7 ng/ml) (P = 0.019). The present study demonstrated that the presence of high levels of both pre-treatment SCC-Ag and CRP acts as a predictor of clinical stage, clinical tumor status, and clinical nodal status in patients with PLC. Moreover, elevated levels of SCC-Ag and CRP were associated with a high metabolic rate as well as the proliferative activity measured according to the SUVmax of the tumor and lymph nodes. Therefore, elevated levels of these two factors have the potential to serve as biomarkers for the prediction of tumor aggressiveness in cases of PLC.

Abstract
BACKGROUND Squamous cell carcinoma antigen (SCC-Ag) level and C-reactive protein (CRP) have been shown to be associated with tumor invasion, lymph node metastasis, staging and survival in patients with oral squamous cell carcinoma (OSCC). The purpose of the present study was to analyze the relationship between preoperative levels of both SCC-Ag and CRP, with clinicopathologic factors and prognosis in OSCC patients. METHODS A retrospective study was performed on 142 OSCC patients between March 2008 and March 2011. Their serum SCC-Ag and CRP levels were measured preoperatively. RESULTS SCC-Ag level of ≥2.0 ng/ml and CRP level ≥5.0 mg/L were significantly associated with pathologic tumor status (P < 0.001), pathologic nodal metastasis (P = 0.001), tumor depth (≥10 mm vs. <10 mm, P < 0.001), disease-free survival (P ≤ 0.001) and overall survival (P ≤ 0.001). The influence of SCC-Ag and CRP level on disease-free survival (hazard ratio 4.046, 95 % confidence interval 1.698-9.692) and overall survival (hazard ratio 3.655, 95 % confidence interval 1.464-9.130) still existed after adjusting for tumor status, lymph node metastasis and tumor cell differentiation. CONCLUSIONS Concurrent high levels of both preoperative SCC-Ag and CRP levels act as a predictor for lymph node metastasis, advanced tumor stage and tumor recurrence. It therefore has significant potential as a biomarker for risk stratification in OSCC.

Abstract
OBJECTIVES/HYPOTHESIS Previous studies have demonstrated a relationship between elevated serum squamous cell carcinoma (SCC) antigen (SCC-Ag) levels and shorter survival in cancer patients. Few studies, however, have investigated the role of serum SCC-Ag levels in oral SCC (OSCC). This study was conducted to analyze the relationship between preoperative SCC-Ag levels, clinicopathologic factors, and prognosis in OSCC patients. STUDY DESIGN Retrospective case-control study. METHODS Seventy-nine OSCC patients from Chang Gung Memorial Hospital were retrospectively recruited between April 2008 and March 2010. Serum SCC-Ag levels were measured preoperatively. RESULTS An SCC-Ag level of ≥2.0 ng/mL was significantly associated with the pathologic tumor status (P < .001), pathologic nodal status (P = .037), lymph node extracapsular spread (P = .016), and tumor depth (>10 mm vs. ≤10 mm, P < .001). It was not significantly associated with histologic differentiation (P = 1.000). A univariate analysis revealed that positivity for SCC-Ag was associated with disease-free survival (DFS) (P = .034) and overall survival (OS) (P < .001). In SCC-Ag-positive patients, the distant metastatic rate was higher than in the SCC-Ag-negative patients (P = .053). CONCLUSIONS This study demonstrated that preoperative SCC-Ag is a good marker of pathologic lymph node metastasis, an advanced tumor stage, and a higher rate of distant metastasis. The preoperative SCC-Ag level is a potential prognostic indicator in DFS and OS, but studies with a longer follow-up period are needed to confirm these results.

Abstract
Squamous cell carcinoma antigen (SCCA) is expressed in normal squamous cell epithelia and in squamous cell carcinomas (SCC). Two nearly identical genes encode the inhibitory serpins SCCA1 (SERPINB3) and SCCA2 (SERPINB4). Serum levels of SCCA are elevated in patients with benign skin diseases and in patients with SCC. SCCA, used for the monitoring of SCC patients, presents no satisfactory diagnostic specificity. As we have shown previously, the reverse transcription polymerase chain reaction (RT-PCR)-based SCCA messenger RNA (mRNA) testing aimed at detecting disseminated cancer cells may be hampered by the false-positive results due to SCCA expression in activated peripheral blood mononuclear cells (PBMC). The aim of this study was to assess the expression of SCCA at mRNA and protein levels in cultured normal PBMC, compared to that in vulvar SCC (VSCC) samples. High SCCA concentrations were found in vulvar tumours and in metastatic lymph nodes, while negative inguinal lymph nodes from the same patients often presented significantly less SCCA. In normal activated PBMC, the level of SCCA protein was the lowest. At the mRNA level SCCA was detectable in normal PBMC even in cultures with no mitogen stimulation, but only by the nested RT-PCR, contrary to VSCC samples found to be SCCA positive already in one-step PCR. Both SCCA1 and SCCA2 transcripts were present in cultured PBMC; SCCA1 was expressed at a higher level than SCCA2. In conclusion, both SCCA forms are detectable in normal PBMC cultured in vitro. SCCA expression level in normal PBMC is much lower than in the squamous epithelium-derived cells. In VSCC, in addition to tumour itself, metastatic lymph nodes seem also to be a potential source of serum SCCA.

Abstract
PURPOSE Recognized prognostic factors do not adequately predict outcomes of head and neck cancer (HNC) patients after their initial treatment. We identified from the literature nine potential serum prognostic markers and assessed whether they improve outcome prediction. EXPERIMENTAL DESIGN A pretreatment serum sample was obtained from 527 of the 540 HNC patients who participated in a randomized controlled trial. During follow-up, 115 had a HNC recurrence, 110 had a second primary cancer (SPC), and 216 died. We measured nine potential serum prognostic markers: prolactin, soluble interleukin-2 (IL-2) receptor-alpha, vascular endothelial growth factor, IL-6, squamous cell carcinoma antigen, free beta-human choriogonadotropin, insulin-like growth factor-I, insulin-like growth factor binding protein-3, and soluble epidermal growth factor receptor. Cox regression was used to identify a reference predictive model for (a) HNC recurrence, (b) SPC incidence, and (c) overall mortality. Each serum marker was added in turn to these reference models to determine by the likelihood ratio test whether it significantly improved outcome prediction. We controlled for the false discovery rate that results from multiple testing. RESULTS IL-6 was the only serum marker that significantly improved outcome prediction. Higher levels of IL-6 were associated with a higher SPC incidence. The hazard ratio comparing the uppermost quartile to the lowest quartile of IL-6 was 2.68 (95% confidence interval, 1.49-4.08). IL-6 was also associated with SPC-specific mortality but not with mortality due to other causes. No marker improved outcome prediction for cancer recurrence or overall mortality. CONCLUSIONS IL-6 significantly improves outcome prediction for SPC in HNC patients.

Abstract
OBJECTIVES/METHODS The intracellular serine protease inhibitor 8 (SERPINB8) is expressed by squamous epithelium, monocytes, and a subset of neuroendocrine cells. Using immunohistochemistry, we now have further investigated the expression of SERPINB8 in normal neuroendocrine cells and its potential use as a marker to identify neuroendocrine tumors of the pancreas. RESULTS In normal neuroendocrine tissues, strongest SERPINB8 expression was detected in islets of Langerhans of the pancreas. Moderate SERPINB8 expression was observed in neuroendocrine cells of the thyroid, adrenal cortex, colon, and pituitary gland. Fluorescent double staining revealed that in the pancreas, SERPINB8 is specifically expressed by insulin-producing beta cells. In a panel of 20 patients with pancreatic islet cell tumors, however, SERPINB8 was broadly expressed and not restricted to insulinomas. In islet cell tumors, SERPINB8 had a similar diagnostic sensitivity as compared with the widely used neuroendocrine markers chromogranin A and synaptophysin. When SERPINB8 was combined with these 2 markers, an even higher diagnostic sensitivity was reached. In contrast, exocrine adenocarcinomas of the pancreas showed no SERPINB8 expression. CONCLUSIONS The SERPINB8 is expressed in normal neuroendocrine cells of several organs as well as in neuroendocrine tumors of the pancreas, where it can be used as an additional diagnostic immunohistochemical marker.

Abstract
Head and neck squamous cell carcinoma (HNSCC) is the sixth most common malignancy and is a major cause of cancer morbidity and mortality worldwide. Oral cancer is the most predominant malignancy in the Indian subcontinent due to the widespread habits of chewing tobacco and related products. Patients with oral tumours have a high risk of early locoregional relapse. Early detection of disease progression remains a challenging task mainly due to the lack of adequate early prognostic markers. CEA, SCC Ag, CA-125, serum cytokeratin (CK) fragments, Cyfra 21-1 (CK 19), TPS (CK 18), TPA (CK 8, 18, and 19) etc. are being used as serum markers for the prediction of prognosis of various malignancies. This review presents the available literature on serum CK markers in different malignancies evaluates their utility in the management of oral cancer, and identifies the lacunae which need to be addressed to develop sensitive and specific assays for early detection of recurrence, prognosis, and treatment monitoring.

Abstract
The expression of high-abundance serum proteins in newly diagnosed patients with endometrial adenocarcinoma (EACa), squamous cell cervical carcinoma (SCCa) and cervical adenocarcinoma (ACCa), relative to control female subjects, was analyzed by subjecting serum samples to 2-DE followed by image analysis of the silver-stained protein profiles. The three cohorts of cancer patients demonstrated different altered expression of serum high-abundance proteins compared to negative control women. The expression of alpha1-antitrypsin, alpha1-B glycoprotein, cleaved high-molecular-weight kininogen (light chain) and antithrombin III were consistently altered in all the patients. However, clusterin was upregulated only in the patients with EACa, while those with SCCa and ACCa were typically characterized by the upregulated expression of zinc alpha-2-glycoprotein. The aberrant expression of selective serum proteins in the various cohorts of cancer patients was validated by competitive ELISA as well as by lectin detection. Analysis by using the champedak galactose binding lectin further highlighted an unidentified protein that may be differently glycosylated in the sera of the EACa patients that were studied.

Abstract
OBJECTIVE Osteopontin (OPN) is a secreted integrin-binding glycophosphoprotein that may have a role in head and neck squamous cell carcinoma (SCC). To evaluate the clinical significance of OPN in esophageal squamous cell carcinoma (ESCC), we compared plasma OPN levels with those of common tumor markers. METHODS Preoperative plasma OPN levels were measured by enzyme immunoassay in 103 ESCC patients. Serum SCC antigen, Cyfra 21-1, and carcinoembryonic antigen (CEA) levels were also measured routinely at admission by radioimmunoassay. RESULTS Plasma OPN levels ranged from 82.8 to 1,980 ng/ml. High OPN level was associated with lymph node metastasis (p = 0.05), but not with tumor histology or depth of invasion. The overall survival of the patients with high OPN levels was worse than that of those with low OPN levels (p = 0.02). SCC antigen and Cyfra 21-1 levels were associated with the depth of tumor invasion, the tumor diameter, lymph node metastasis, and the overall survival, but CEA was not associated with these clinicopathological factors. Combined evaluation of OPN plus Cyfra 21-1 or OPN plus SCC antigen was useful as an independent prognostic indicator. CONCLUSION Measurement of the plasma OPN level, as well as serum SCC antigen and Cyfra 21-1, may help to predict the progression of ESCC.

Abstract
BACKGROUND Increased preoperative serum squamous cell carcinoma antigen (SCC-Ag) concentrations have been found to be associated with advanced stage and poor prognosis in lung and cervical cancers. Because little was known about the significance of SCC-Ag concentration in patients with esophageal cancer, the aim of this study was to analyze the clinicopathologic significance of SCC-Ag in patients with esophageal SCC. PATIENTS AND METHODS. Preoperative SCC-Ag concentration was measured with enzyme-linked immunosorbent assay in 309 patients with primary esophageal SCC. All patients underwent curative radical surgery without any preoperative therapy. In 215 of 309 patients, carcinoembryonic antigen (CEA) was also measured to compare clinical significance of CEA with that of SCC-Ag. The prognostic significance for survival of SCC-Ag concentrations was studied with multivariate analysis with Cox proportional hazards model. RESULTS The SCC-Ag concentration and the positivity rate of SCC-Ag were significantly elevated in patients associated with tumor progression. Statistically significant differences in SCC-Ag concentrations and SCC-Ag positivity rates were observed depending on tumor size, tumor depth, lymph node status, and distant metastasis. Although CEA was not a prognostic factor (P =.21), a high SCC-Ag concentration was a significant prognostic factor (P <.01). Multivariate analyses indicated that T factor had the best predictive power, but SCC-Ag concentration contained additional, independent prognostic information. CONCLUSION Our findings suggest that preoperative serum SCC-Ag concentrations might provide a predictive information for tumor progression and survival in patients with esophageal SCC.

Abstract
BACKGROUND Inverted papilloma (IP) is a frequent benign sinonasal tumor that is characterized histologically by squamous metaplasia, epithelial acanthosis, and hyperplasia of the nasal epithelium. Because of its high recurrence rate and malignant transformation potential, careful long-term follow up is necessary. METHODS The purpose of the current report was to study the expression of squamous cell carcinoma (SCC) antigen in sinonasal IPs and to evaluate the usefulness of SCC antigen as a biologic marker for the follow-up of patients with sinonasal IP. The expression of SCCA1 in three sinonasal IP cases, three sinonasal SCC cases, and cases of normal nasal epithelium were examined by Western blot analysis, and the SCCA1 expression pattern in 31 IP specimens and 4 carcinoma in IP specimens were evaluated immunohistochemically. The serum levels of SCC antigen in 11 patients with sinonasal IP also were analyzed. RESULTS SCCA1 was overexpressed in all three sinonasal IP tissues compared with sinonasal SCC tissues or normal nasal epithelium. SCCA1 cytoplasmic immunoreactivity was detected in the suprabasal epidermal keratinocytes of all 31 sinonasal IP cases. In the four carcinoma in IP specimens, SCCA1 expression in the papillomatous lesion was more intense than in the cancerous lesion. The serum SCC antigen level was high in 10 of 11 patients with IP (91%) and significantly decreased after surgical resection of the tumors. CONCLUSIONS The results of the current study indicate that SCCA1 frequently is overexpressed and may play a biologic role in the development of sinonasal IPs. Serum SCC antigen may be a useful biologic marker in patients with sinonasal IP.

Abstract
Squamous cell carcinoma (SCC) antigen has been used for the management of SCC arising in various cites including head and neck region. However, the true mechanism of the elevation of this protein in the serum of patients with SCC is still unknown. SCC antigen belongs to the superfamily of serine protease inhibitors. Recently, molecular studies show that serum SCC antigen is transcribed by two nearly identical genes (SCCA1 and SCCA2), and is mainly produced by SCCA1. The objective of this study is to clarify the mechanism of the elevation of SCC antigen in oral tongue SCC patients and to identify cells histologically, which are responsible for serum SCC antigen production. In this study, we examined SCCA1 expression in a series of four head and neck SCC (HNSCC) cell lines, and found that all expressed equal to low SCCA1 protein as compared with the normal human oral keratinocyte. Using the double immunohistochemical technique to examine the expression pattern of SCCA1 in 86 cases of oral tongue squamous cell carcinoma, SCCA1 immunostaining was observed in the cytoplasm of cancer cells and T-lymphocytes peripheral to cancer cells. We also compared the clinicopathological features including serum SCC antigen level of the oral tongue SCC cases with the immunohistochemical SCCA1 expression pattern, and found that elevated serum SCC antigen level was significantly correlated with SCCA1 expression not in cancer cells, but in T-lymphocytes peripheral to cancer cells. These results suggest that T-lymphocytes peripheral to cancer cells may be responsible for serum SCC antigen production in HNSCC patients.

Abstract
The ability to reliably predict cancer outcome could tailor therapy to the aggressiveness of the tumour to achieve the best results in terms of loco-regional control, overall survival and quality of life. Retrospective and prospective clinical trials involving large series of patients have validated some predictive clinical and pathological factors, whereas the utility of many other prognostic factors has not been established. This has led to some confusion in clinical practice. In order to clarify the significance, role and cost of these prognostic factors we carried out a Medline search of all papers published between 1993 and 1998 concerning the reliability and cost of markers with prognostic significance, in head and neck squamous cell carcinoma, and assessed the results according to a number of criteria relating to reliability and cost. Regarding reliability we classified prognostic factors into: (1) those with a proven significance based on the fact that they were unanimously reported as having an independent statistical correlation with outcome and prognosis; and (2) those for which results were not unanimous, and which significance is still controversial. Cost analysis showed a substantial difference between validated tests which are of low cost and experimental tests which are expensive. Based on these data regarding both the reliability and cost of each prognostic factor, we propose guidelines for their use in clinical practice in the year 2000.

Abstract
Patients with head and neck squamous cell cancer have cell-mediated immune defects and anergy, which progress with disease. T-lymphocytopenia and dysfunction, monocyte dysfunction, prostaglandins, antigen-antibody complexes, serum and cell suppressive factors, radiation therapy and poor nutrition with zinc deficiency all contribute. Nevertheless, cell-mediated immunoreactivity to tumor is manifest in the majority of the patient's blood and regional nodes, and in the tumor itself by tumor-infiltrating lymphocytes. Lymphocytes from these sources cloned in the presence of interleukin-2 +/- tumor extracts show relatively specific cytotoxicity against squamous cell cancer. Humoral immunity is intact, and increased IgA and IgE levels and antibodies reactive to tumor antigens are common. Tumor-associated antigens detected in serum and tumor include carcinoembryonic antigen, tumor polypeptide antigen, squamous cell cancer antigens, tumor antigen-4 and various mucin antigens. The mucin antigens, in particular, can elicit T-cell responses. Humoral reactivity to such antigens is manifest in circulating immune complexes and immunoglobulin coating of tumor surfaces. Immunotherapeutic efforts in head and neck squamous cell cancer should logically employ T-cell adjuvants, contrasuppression and immunorestoration. Non-specific stimulation with bacille Calmette-Guerin (BCG), levamisole and other agents has not been successful. Encouraging results have been observed in limited trials with indomethacin and plasmapheresis. Early trials with local administration of low dosages of interferon-alpha, natural interleukin-2 and a natural interleukin mixture have produced partial and complete regressions with no toxicity and with intense leukocyte infiltration indicating cellular immunity. Efforts are needed to define the mechanisms and the antigens involved in these reactions. On the contrary, treatments with high dosages of recombinant interferon-alpha and interleukin-2 have yielded few responses and considerable toxicity. Combination strategies are discussed which may improve upon these initial immunotherapeutic effects of these low dose trials.
