Development, Implementation and Application of Confocal Laser Endomicroscopy in Brain, Head and Neck Surgery—A Review. Diagnostics (Basel) 2022; 12:diagnostics12112697. [PMID: 36359540 PMCID: PMC9689276 DOI: 10.3390/diagnostics12112697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 10/20/2022] [Accepted: 10/25/2022] [Indexed: 11/09/2022] Open
Abstract
When we talk about visualization methods in surgery, it is important to mention that the diagnosis of tumors and how we define tumor borders intraoperatively in a correct way are two main things that would not be possible to achieve without this grand variety of visualization methods we have at our disposal nowadays. In addition, histopathology also plays a very important role, and its importance cannot be neglected either. Some biopsy specimens, e.g., frozen sections, are examined by a histopathologist and lead to tumor diagnosis and the definition of its borders. Furthermore, surgical resection is a very important point when it comes to prognosis and life survival. Confocal laser endomicroscopy (CLE) is an imaging technique that provides microscopic information on the tissue in real time. CLE of disorders, such as head, neck and brain tumors, has only recently been suggested to contribute to both immediate tumor characterization and detection. It can be used as an additional tool for surgical biopsies during biopsy or surgical procedures and for inspection of resection margins during surgery. In this review, we analyze the development, implementation, advantages and disadvantages as well as the future directions of this technique in neurosurgical and otorhinolaryngological disciplines.

Diagnostic Accuracy of Confocal Laser Endomicroscopy for the Diagnosis of Oral Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182312390. [PMID: 34886116 PMCID: PMC8657406 DOI: 10.3390/ijerph182312390] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 11/18/2021] [Accepted: 11/18/2021] [Indexed: 01/22/2023]
Abstract
Background: Advances in treatment approaches for patients with oral squamous cell carcinoma (OSCC) have been unsuccessful in preventing frequent recurrences and distant metastases, leading to a poor prognosis. Early detection and prevention enable an improved 5-year survival and better prognosis. Confocal Laser Endomicroscopy (CLE) is a non-invasive imaging instrument that could enable an earlier diagnosis and possibly help in reducing unnecessary invasive surgical procedures. Objective: To present an up to date systematic review and meta-analysis assessing the diagnostic accuracy of CLE in diagnosing OSCC. Materials and Methods. PubMed, Scopus, and Web of Science databases were explored up to 30 June 2021, to collect articles concerning the diagnosis of OSCC through CLE. Screening: data extraction and appraisal was done by two reviewers. The quality of the methodology followed by the studies included in this review was assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. A random effects model was used for the meta-analysis. Results: Six studies were included, leading to a total number of 361 lesions in 213 patients. The pooled sensitivity and specificity were 95% (95% CI, 92–97%; I2 = 77.5%) and 93% (95% CI, 90–95%; I2 = 68.6%); the pooled positive likelihood ratios and negative likelihood ratios were 10.85 (95% CI, 5.4–21.7; I2 = 55.9%) and 0.08 (95% CI, 0.03–0.2; I2 = 83.5%); and the pooled diagnostic odds ratio was 174.45 (95% CI, 34.51–881.69; I2 = 73.6%). Although risk of bias and heterogeneity is observed, this study validates that CLE may have a noteworthy clinical influence on the diagnosis of OSCC, through its high sensitivity and specificity. Conclusions: This review indicates an exceptionally high sensitivity and specificity of CLE for diagnosing OSCC. Whilst it is a promising diagnostic instrument, the limited number of existing studies and potential risk of bias of included studies does not allow us to draw firm conclusions. A conclusive inference can be drawn when more studies, possibly with homogeneous methodological approach, are performed.

Tumor Budding and Cell Nest Size Are Highly Prognostic in Laryngeal and Hypopharyngeal Squamous Cell Carcinoma: Further Evidence for a Unified Histopathologic Grading System for Squamous Cell Carcinomas of the Upper Aerodigestive Tract. Am J Surg Pathol 2020; 43:303-313.

Abstract
Squamous cell carcinoma (SCC) is the most common cancer of the head and neck region including-among others-laryngeal (LSCC) and hypopharyngeal (HSCC) subsites. LSCC/HSCC are heterogenous diseases with respect to patient outcome. Currently, tumor stage-based patient stratification is essential to predict prognosis and thus selection of the appropriate treatment modalities. In contrast, the prognostic impact of the current HSCC/LSCC grading system according to the WHO classification is limited. Recently, a novel grading system based on tumor budding activity (BA) and cell nest size (CNS) has been introduced for SCC in different anatomic regions of the upper aerodigestive tract. To test and transvalidate this grading scheme in LSCC and HSCC, we retrospectively correlated BA, CNS, and additional histomorphologic parameters with clinicopathologic data of 157 treatment-naive patients. In doing so, we demonstrate that a 3-tiered novel grading system (well-differentiated [nG1], intermediately [nG2], and poorly differentiated [nG3]) based on a sum score for BA and CNS is highly and independently prognostic for patient survival in LSCC/HSCC, strongly outperforming the current WHO grading scheme with a hazard ratio for disease-specific survival of 6.6 for nG2 and 13.4 for nG3 cases (P<0.001). This finding contributes to a growing body of evidence that a CNS and BA-based pan-entity grading system in SCC might be useful and seems to capture differences in underlying SCC biology crucial for survival.

Diffusion-weighted Magnetic Resonance Imaging for Predicting Response to Chemoradiation Therapy for Head and Neck Squamous Cell Carcinoma: A Systematic Review. Korean J Radiol 2020; 20:649-661. [PMID: 30887747 PMCID: PMC6424826 DOI: 10.3348/kjr.2018.0446] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2018] [Accepted: 11/11/2018] [Indexed: 12/18/2022] Open
Abstract
OBJECTIVE To systematically review the evaluation of the diagnostic accuracy of pre-treatment apparent diffusion coefficient (ADC) and change in ADC during the intra- or post-treatment period, for the prediction of locoregional failure in patients with head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS Ovid-MEDLINE and Embase databases were searched up to September 8, 2018, for studies on the use of diffusion-weighted magnetic resonance imaging for the prediction of locoregional treatment response in patients with HNSCC treated with chemoradiation or radiation therapy. Risk of bias was assessed by using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. RESULTS Twelve studies were included in the systematic review, and diagnostic accuracy assessment was performed using seven studies. High pre-treatment ADC showed inconsistent results with the tendency for locoregional failure, whereas all studies evaluating changes in ADC showed consistent results of a lower rise in ADC in patients with locoregional failure compared to those with locoregional control. The sensitivities and specificities of pre-treatment ADC and change in ADC for predicting locoregional failure were relatively high (range: 50-100% and 79-96%, 75-100% and 69-95%, respectively). Meta-analytic pooling was not performed due to the apparent heterogeneity in these values. CONCLUSION High pre-treatment ADC and low rise in early intra-treatment or post-treatment ADC with chemoradiation, could be indicators of locoregional failure in patients with HNSCC. However, as the studies are few, heterogeneous, and at high risk for bias, the sensitivity and specificity of these parameters for predicting the treatment response are yet to be determined.

Predictive value of quantitative diffusion-weighted imaging and 18-F-FDG-PET in head and neck squamous cell carcinoma treated by (chemo)radiotherapy. Eur J Radiol 2019; 113:39-50. [PMID: 30927958 DOI: 10.1016/j.ejrad.2019.01.031] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2018] [Revised: 12/28/2018] [Accepted: 01/29/2019] [Indexed: 01/15/2023]
Abstract
BACKGROUND AND PURPOSE In head and neck squamous cell carcinoma (HNSCC) (chemo)radiotherapy is increasingly used to preserve organ functionality. The purpose of this study was to identify predictive pretreatment DWI- and 18F-FDG-PET/CT-parameters for treatment failure (TF), locoregional recurrence (LR) and death in HNSCC patients treated by (chemo)radiotherapy. MATERIALS AND METHODS We retrospectively included 134 histologically proven HNSCC patients treated with (chemo)radiotherapy between 2012-2017. In 58 patients pre-treatment DWI and 18F-FDG-PET/CT were performed, in 31 patients DWI only and in 45 patients 18F-FDG-PET/CT only. Primary tumor (PT) and largest lymph node (LN) metastasis were quantitatively assessed for TF, LR and death. Multivariate analysis was performed for 18F-FDG-PET/CT and DWI separately and thereafter combined. In patients with both imaging modalities, positive and negative predictive value in TF and differences in LR and death, were assessed. RESULTS Mean follow-up was 25.6 months (interquartile-range; 14.0-37.1 months). Predictors of treatment failure, corrected for TNM-stage and HPV-status, were SUVmax-PT, ADCmax-PT, total lesion glycolysis (TLG-LN), ADCp20-LN (P = 0.049, P = 0.024, P = 0.031, P = 0.047, respectively). TLG-PT was predictive for LR (P = 0.003). Metabolic active tumor volume (MATV-PT) (P = 0.003), ADCGTV-PT (P < 0.001), ADCSD (P = 0.048) were significant predictors for death. In patients with both imaging modalities SUVmax-PT remained predictive for treatment failure (P = 0.049), TLG-LN for LR (P = 0.003) and ADCGTV-PT for death (P < 0.001). Higher predictive value for treatment failure was found for the combination of SUVmax-PT and ADCmax-PT, compared to either one separately. CONCLUSION Both DWI- and 18F-FDG-PET/CT-parameters appear to have predictive value for treatment failure, locoregional recurrence and death. Combining SUVmax-PT and ADCmax-PT resulted in better prediction of treatment failure compared to single parameter assessment.

Prognostic value of maximum standardized uptake value measured by pretreatment 18F-FDG PET/CT in locally advanced head and neck squamous cell carcinoma. Clin Transl Oncol 2017; 19:1337-1349. [PMID: 28540535 DOI: 10.1007/s12094-017-1674-6] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Accepted: 05/12/2017] [Indexed: 11/24/2022]
Abstract
PURPOSE/OBJECTIVES To evaluate the prognostic impact of maximum standardized uptake value (SUVmax) in patients with locally advanced head and neck squamous cell carcinoma (HNSCC) undergoing pretreatment [F-18] fluoro-D-glucose-positron emission tomography/computed tomography (FDG PET/CT) imaging. MATERIALS/METHODS Fifty-eight patients undergoing FDG PET/CT before radical treatment with definitive radiotherapy (±concomitant chemotherapy) or surgery + postoperative (chemo)radiation were analyzed. The effects of clinicopathological factors (age, gender, tumor location, stage, Karnofsky Performance Status (KPS), and treatment strategy) including primary tumor SUVmax and nodal SUVmax on overall survival (OS), disease-free survival (DFS), locoregional control (LRC), and distant metastasis-free survival (DMFS) were evaluated. Kaplan-Meier survival curves were generated and compared with the log-rank test. RESULTS Median follow-up for the whole population was 31 months (range 2.3-53.5). Two-year OS, LRC, DFS and DMFS, for the entire cohort were 62.1, 78.3, 55.2 and 67.2%, respectively. Median pretreatment SUVmax for the primary tumor and lymph nodes was 11.85 and 5.4, respectively. According to univariate analysis, patients with KPS < 80% (p < 0.001), AJCC stage IVa or IVb vs III (p = 0.037) and patients undergoing radiotherapy vs surgery (p = 0.042) were significantly associated with worse OS. Patients with KPS < 80% (p = 0.003) or age ≥65 years (p = 0.007) had worse LRC. The KPS < 80% was the only factor associated with decreased DFS (p = 0.001). SUVmax of the primary tumor or the lymph nodes were not associated with OS, DFS or LRC. The KPS < 80% (p = 0.002), tumor location (p = 0.047) and AJCC stage (p = 0.025) were associated with worse cancer-specific survival (CSS). According to Cox regression analysis, on multivariate analysis KPS < 80% was the only independent parameter determining worse OS, DFS, CSS. Regarding LRC only patients with IK < 80% (p = 0.01) and ≥65 years (p = 0.01) remained statistically significant. Nodal SUVmax was the only factor associated with decreased DMFS. Patients with a nodal SUVmax > 5.4 presented an increased risk for distant metastases (HR, 3.3; 95% CI 1.17-9.25; p = 0.023). CONCLUSIONS The pretreatment nodal SUVmax in patients with locally advanced HNSCC is prognostic for DMFS. However, according to our results primary tumor SUVmax and nodal SUVmax were not significantly related to OS, DFS or LRC. Patients presenting KPS < 80% had worse OS, DFS, CSS and LRC.

Abstract
Confocal laser endomicroscopy (CLE) is an imaging technique that uses miniaturized fiberoptic probes to allow real-time histological imaging of human tissue. An application of CLE in otorhinolaryngology has hardly been investigated so far. In our study, we analyzed the applicability of CLE to visualize cancerous and healthy tissue of the head and neck region. Formalin-fixed tissue specimens from 135 head and neck squamous cell carcinoma (HNSCC) patients and 50 healthy controls were investigated using CLE with and without topical application of acriflavine. Four head and neck surgeons, four pathologists, and four laymen evaluated the CLE images of the HNSCC cases regarding the tumor localization and its border to healthy tissue. The tumor localization and the tumor border were correctly identified in 97 % by the pathologists, 85 % by the head and neck surgeons, and 70 % by the laymen. The main difference in evaluation results was seen in the correct identification of the tumor site (p < 0.05), while there was no significant difference in the identification of the tumor border. CLE is a valuable tool for real-time histological imaging of HNSCCs. It can help to visualize the tumor border and, thereby, facilitate a more precise tumor surgery.

Abstract
Tumor development and progression are multistep processes that involve local tumor growth and invasion, followed by metastasis. The aggressiveness of the tumor is the major determinant of the mortality of oral cancer patients. The present study investigates whether the expression levels of cyclooxygenase-2 (COX-2), nuclear factor-κB (NF-κB), peroxiredoxin 1 (PRDX1) and PRDX6 are associated with the development, proliferation, differentiation and recurrence of oral squamous cell carcinoma (OSCC). The mRNA expression levels of COX-2, NF-κB, PRDX1 and PRDX6 were examined in 50 OSCC specimens and 19 normal oral mucosae by quantitative polymerase chain reaction (qPCR). qPCR analysis showed that the mRNA levels of COX-2 in OSCC were significantly higher than those in the normal oral mucosae (P=0.021). The expression levels of PRDX1 in high-stage tumors (T3 and T4) were significantly elevated compared with those in low-stage tumors (T1) (P=0.047). Additionally, the expression levels of NF-κB in the high-grade tumor were significantly elevated compared with those in the low-grade tumors (P=0.030). Overall, it was indicated that the expression of COX-2 is strongly associated with the development of OSCC. Moreover, the enhanced expression of PRDX1 and NF-κB may function in the progression of OSCC, which serves as a useful marker for prognosis in patients with oral cancer.

Abstract
Much recent attention has highlighted a subset of head and neck squamous cell carcinomas (HNSCCs) related to human papillomavirus (HPV) that has an epidemiologic, demographic, molecular and clinical profile which is distinct from non-HPV-related HNSCC. The clinical significance of detecting HPV in a HNSCC has resulted in a growing expectation for HPV testing of HNSCCs. Although the growing demand for routine testing is understandable and appropriate, it has impelled an undisciplined approach that has been largely unsystematic. The current state of the art has now arrived at a point where a better understanding of HPV-related tumorigenesis and a growing experience with HPV testing can now move wide scale, indiscriminant and non-standardized testing towards a more directed, clinically relevant and standardized approach. This review will address the current state of HPV detection; and will focus on why HPV testing is important, when HPV testing is appropriate, and how to test for the presence of HPV in various clinical samples. As no single test has been universally accepted as a best method, this review will consider the strengths and weaknesses of some of the more commonly used assays, and will emphasize some emerging techniques that may improve the efficiency of HPV testing of clinical samples including cytologic specimens.

Low blood levels of sTWEAK are related to locoregional failure in head and neck cancer. Eur Arch Otorhinolaryngol 2014; 272:1733-41. [PMID: 24858806 DOI: 10.1007/s00405-014-3095-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2014] [Accepted: 05/07/2014] [Indexed: 01/28/2023]
Abstract
Identifying serum pre-treatment molecular markers that can predict response to therapy is of great interest in head and neck oncology and is required to develop personalized treatments that maximize survival while minimizing morbidity. The main aim was to investigate the potential prognostic significance of tumor necrosis factor-like weak inducer of apoptosis (TWEAK), and its receptors, fibroblast growth factor-inducible 14 (Fn14) and CD163, in head and neck squamous cell carcinoma (HNSCC). The study comprised 37 consecutive patients with pathologically confirmed, untreated HNSCC. Serum and tissue samples from these patients were available for study. We determined sTWEAK and sCD163 levels in serum from 37 HNSCC patients by ELISA. TWEAK, CD163, Fn14 and TNF-α gene expression were detected by real-time RT-PCR in 111 matched tissue samples (tumoral, adjacent and distal/normal mucosa). Our results showed a significant relationship between low sTWEAK levels and poor locoregional control of the disease. Kaplan-Meier curves indicated that the locoregional recurrence-free survival rate in patients with low sTWEAK circulating levels was significantly lower than in patients with high levels, and that high CD136/TWEAK expression ratio in tumors was also related to poor prognosis. sTWEAK pre-treatment serum levels might be used as prognostic non-invasive biomarkers for locoregional control in patients with HNSCC. Future investigations are warranted to determine the potential prognostic significance of this non-invasive biomarker in the rapid discrimination according to the locoregional control achieved in patients who received a non-surgical organ preservation treatment.

Casein kinase 1 epsilon expression predicts poorer prognosis in low T-stage oral cancer patients. Int J Mol Sci 2014; 15:2876-91. [PMID: 24557581 PMCID: PMC3958887 DOI: 10.3390/ijms15022876] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2013] [Revised: 02/13/2014] [Accepted: 02/17/2014] [Indexed: 11/17/2022] Open
Abstract
Casein kinase 1 is a group of ubiquitous serine/threonine kinases that are involved in normal cellular functions and several pathological conditions, such as DNA repair, cell cycle progression, cytokinesis, differentiation, and apoptosis. Recent studies have indicated that casein kinase 1-epsilon (CK1ε) and casein kinase 1-delta (CK1δ) expression has a role in human cancers. We investigated the associations between CK1ε and CK1δ expression and the clinical parameters of oral cancer using immunohistochemical study methods on oral squamous cell carcinoma specimens. The results of our immunohistochemical analysis showed that the loss of CK1ε expression was greatly associated with a poor four-year survival rate in oral cancer patients (p = 0.002). A Kaplan-Meier analysis showed that patients who had a loss of CK1ε expression had a considerably poorer overall survival rate than patients who had positive CK1ε expressions (p = 0.022). A univariate analysis revealed that patients who had a loss of CK1ε expression had considerably poorer overall survival (OS) than patients who had positive expression (p = 0.024, hazard ratio (HR) = 1.7). In conclusion, our data indicated that the loss of cytoplasmic CK1ε expression is greatly associated with poor survival and might be an adverse survival factor.

Abstract
BACKGROUND AND PURPOSE ADC provides a measure of water molecule diffusion in tissue. The aim of this study was to evaluate whether the fractional change in ADC during therapy can be used as a valid predictive indicator of treatment response in head and neck squamous cell carcinoma treated with chemoradiotherapy. MATERIALS AND METHODS Forty patients underwent DWI at pretreatment and 3 weeks after the start of treatment. The pretreatment ADC, fractional change in ADC, tumor regression rate, and other clinical variables were compared with locoregional control and locoregional failure and were analyzed by using logistic regression analysis and receiver operating characteristic analysis. Furthermore, progression-free survival curves divided by the corresponding threshold value were compared by means of the log-rank test. RESULTS The fractional change in ADCprimary, the fractional change in ADCnode, primary tumor volume, nodal volume, tumor regression ratenode, N stage, and tumor location revealed significant differences between locoregional failure and locoregional control (P < .05). In univariate analysis, the fractional change in ADCprimary, fractional change in ADCnode, tumor regression ratenode, N stage, and tumor location showed significant association with locoregional control (P < .05). In multivariate analysis, however, only the fractional change in ADCprimary was identified as a significant and independent predictor of locoregional control (P = .04). A threshold fractional change in ADCprimary of 0.24 revealed a sensitivity of 100%, specificity of 78.7%, and overall accuracy of 84.8% for the prediction of locoregional control. Progression-free survival of the 2 groups divided by the fractional change in ADCprimary at 0.24 showed a significant difference (P < .05). CONCLUSIONS The results suggest that the fractional change in ADCprimary is a valid imaging biomarker for predicting treatment response in head and neck squamous cell carcinoma treated with chemoradiotherapy.

Abstract
PURPOSE Locally advanced head and neck squamous cell carcinoma (HNSCC) has a high rate of recurrence. Induction chemotherapy with DCF (docetaxel, cisplatin, 5-fluorouracil) before chemoradiotherapy could lead to the best disease control of inoperable stage III/IV HNSCC but with an increased risk of acute toxicity. Early assessment of therapeutic efficacy is a key issue in considering the benefit of escalation in a poor prognosis population. METHODS Patients with stage III/IV HNSCC, in whom DCF induction chemotherapy followed by concurrent chemoradiotherapy had been validated by a multidisciplinary team, were prospectively included in the study. FDG PET/CT scans were performed in all patients before and after two of the three cycles of DCF. EORTC99 criteria were used to evaluate PET responses as follows: group 1 (metabolic responders) showing a complete response (CR) or partial response (PR), and subgroup 0 (metabolic nonresponders) showing stable disease (SD) or progressive disease (PD). The primary endpoint for monitoring patients was event-free survival (EFS). EFS probabilities between the two groups were estimated by the Kaplan-Meier method and statistically compared using the log-rank test. RESULTS Fifteen consecutive patients (14 men, 1 woman; age 57.5 ± 6.2 years, mean ± SD) were analysed. Therapeutic assessment by PET/CT demonstrated CR in four patients, PR in six, SD in four and PD in one. Among the ten patients with a metabolic response (group 1), none had relapsed at the time of this report, while four of five patients with no metabolic response (group 0) showed recurrence within an average of 9.0 ± 1.6 months. Median EFS was, respectively, 18.9 months (3.8-25.3 months) and 10.2 months (7.5-12.7 months) in group 1 and group 0. The corresponding 1-year EFS rates were 100 % and 20 %, respectively. The difference in EFS between the two groups was statistically significant (p = 0.0014). CONCLUSION Early therapeutic response demonstrated on FDG PET/CT after two cycles of induction chemotherapy with DCF in patients with inoperable stage III/IV HNSCC seems to be a predictive factor for EFS.

Abstract
PURPOSE To compare primary tumor (18)F-fluorodeoxyglucose (FDG) maximum standardized uptake value (SUV(max)) and diffusion-weighted imaging (DWI) apparent diffusion coefficient (ADC) obtained in the same patients with head and neck squamous cell carcinoma (HNSCC) to clarify the prognostic significance of both indexes. MATERIALS AND METHODS The study population comprised 26 patients with HNSCC visible on both pretreatment FDG PET/CT and DWI. Correlation between SUV(max) and ADC (b values; 0 and 800 seconds/mm(2)) was analyzed by the Spearman's rank test. Disease-free survival (DFS) was calculated by the Kaplan-Meier method. Prognostic significance was assessed by the long-rank test and Cox proportional hazards analysis. RESULTS SUV(max) and ADC correlated significantly and negatively (ρ = -0.566, P = 0.005). High (>12.1) SUV(max) (P < 0.001), low (≤ 0.88) ADC (P = 0.009), high (T3-4) T stage (P = 0.030), and high (N2-3) N stage (P = 0.007) were significant in predicting poor 2-year DFS. The accuracy for predicting disease events was 81% (21/26) for SUV(max) (>12.1) and 73% (19/26) for ADC(≤ 0.88) without significant difference between them (P = 0.52). Disease event hazards ratios for significant unadjusted SUV(max) (P = 0.015) and ADC (P = 0.039) remained significant when adjusted for other dichotomized clinical covariates (SUV(max); P = 0.009-0.039, ADC; P = 0.017-0.037) except SUV(max) for ADC and ADC for SUV(max) and T stage. CONCLUSION These results suggest that pretreatment primary tumor SUV(max) and ADC correlate significantly and negatively and both may have similar potential to predict DFS or disease events of HNSCC.

Loss of nuclear expression of Krüppel-like factor 4 is associated with poor prognosis in patients with oral cancer. Hum Pathol 2011; 43:1119-25.

Abstract
Krüppel-like factor 4 is not only involved in cell proliferation but also affects cell differentiation and extracellular matrix production via positive and negative regulation of the expression of a wide range of genes. To our knowledge, little information is available regarding the role of Krüppel-like factor 4 in oral squamous cell carcinoma. In this study, we investigated the associations between Krüppel-like factor 4 expression and clinical parameters of oral cancer using immunohistochemical assays in 215 surgical specimens. Compared with positive nuclear Krüppel-like factor 4 expression, we observed that negative nuclear Krüppel-like factor 4 expression was significantly associated with an advanced cancer stage (P = .046), a high tumor recurrence rate (P = .009), and a worse 3-year survival rate in patients with oral cancer (P = .046). Nuclear expression of Krüppel-like factor 4 was shown to have an inverse relationship with Ki67 expression (P = .046). Patients with negative nuclear expression of Krüppel-like factor 4 had significantly worse overall survival rates as defined by the log-rank test (P = .014). Patients with oral cancer with negative nuclear Krüppel-like factor 4 expression in tumor cells had poor prognoses and a 2.5-fold higher death risk. Compared with disease stage (P = .025), negative nuclear Krüppel-like factor 4 expression (P = .006) was an independent prognostic factor. Our results revealed that the loss of nuclear expression of Krüppel-like factor 4 is significantly associated with aggressive clinical manifestations and might be an adverse survival factor.

Abstract
BACKGROUND High uptake of 2-[(18)F]-fluoro-2-deoxy-D-glucose (FDG) is associated with unfavorable results. Pretreatment FDG uptake was evaluated as a predictor of survival and guidance for primary surgery or radiotherapy (RT) in patients with squamous cell carcinoma (SCC) of the larynx and hypopharynx. MATERIALS AND METHODS Seventy-nine consecutive patients with newly diagnosed advanced resectable SCC of the larynx and hypopharynx underwent FDG positron emission tomography (PET) before surgical resection plus RT and chemotherapy (surgery group, n=40) or RT with chemotherapy and surgical salvage (RT group, n=39). Age, tumor stage, histological grade, treatment strategy, and standardized uptake value (SUV) were analyzed for association with local control and survival. RESULTS Overall local control and survival in the two groups did not differ (P>0.1). In univariate analysis, nodal positivity (P=0.014) and SUV>8.0 (P=0.007) were associated with poorer disease-free survival (DFS). In multivariate analysis, SUV remained an independent determinant of DFS (P=0.014). When patients with SUV>8.0 in the two treatment groups were analyzed separately, those in the surgery group tended to have a higher 3-year DFS than those in the RT group, despite no statistical significance (48% vs. 27%, P=0.085). CONCLUSIONS High FDG uptake is associated with poor survival in patients with advanced laryngopharyngeal SCC. Patients with high FDG uptake may be better treated by surgical resection followed by RT and chemotherapy.

Abstract
BACKGROUND The purpose of this study was to investigate the incidence and clinical significance of genetically diagnosed lymph node micrometastasis for patients with oral squamous cell carcinoma (SCC). METHODS A total of 495 lymph nodes obtained from 21 patients with primary oral SCCs that had p53 mutations were examined for corresponding p53 mutations in lymph nodes using mutant allele-specific amplification (MASA). RESULTS Among 476 histologically negative nodes, 44 were scored as positive for metastasis by MASA. All 19 histologically positive lymph nodes were genetically positive. Four of the 10 pN0 cases and nine of the 11 pN-positive cases had genetically positive micrometastases. Four patients who had five or more genetically positive lymph nodes located in three or more levels, three with disease staged as pN0 or pN1, died of cancer. CONCLUSIONS These results indicate that a high rate of micrometastasis in cervical lymph nodes of oral SCCs and patients with multiple or lower neck spread of micrometastases have a poor prognosis; they should be treated with postoperative adjuvant therapy.

Abstract
Squamous cell cancer in the head and neck region (HNSC) is unique concerning its progression since it remains locoregional for long time and visceral metastases develop only in a later stage of the disease. Accordingly, molecular markers of the local invasion and the lymphatic dissemination both have critical importance. HNSC progression is associated with deregulated control of cell proliferation and apoptosis but it seems equally significant the disregulation of the proteolytic machineries. Here we outline the lymphatic metastatic cascade for HNSC to depict key molecular determinants as possible prognostic factors or therapeutic targets identifying immunological selection as a major feature. Unlike in local spreading, invasive potential of cancer cells seems to be less significant during lymphatic dissemination due to the anatomical properties of the lymphatic vessels and tissues. There is a general believe that HNSC is one disease however, data indicate that the anatomical localization of the tumor (the "soil") such as oral, lingual, glottic or pharyngeal has a significant effect on the gene expression profile and corresponding biological behavior of HNSC. Furthermore, even the endocrine milieu of the host was proved to be influential in modulating the progression of HNSC. Gene expression profiling techniques combined with proteomics could help to define and select usefull genetic and biomarkers of progression of HNSC, some of them could well be potential novel therapeutic target.

Abstract
Galectin-3, is a multifunctional effector. It is the only chimera-type member of the galectin family of endogenous lectins, which share specificity with beta-galactosides and have a jelly-roll-like folding pattern. It's activity profile includes modulation of cell-cell and cell-extracellular matrix interactions and the regulation of proliferation and apoptosis/anoikis. While lectin histochemistry with plant/invertebrate proteins is routine practice and immunohistochemical analysis of endogenous lectins has been thoroughly examined, the application of an endogenous lectin as a marker is presently primarily a promising concept. The aims of our study were to test galectin-3 as a technical probe and to correlate staining by the tissue lectin, localising accessible ligands in situ, to clinicopathological characteristics and the prognosis of patients (relapse-free and overall survival) in advanced head and neck squamous cell cancer. We measured galectin-3-dependent staining in 53 surgically resected oropharyngeal and laryngeal cancer specimens (stage III or IV). Patients were divided into two groups based on a threshold of 5% positivity in the tumour cell population. The patient's degree of positivity was significantly correlated with their level of differentiation and keratinisation and lack of lymph node involvement (P=0.0001, P=0.0007 and P=0.0224, respectively). Periods of relapse-free and overall survival were significantly shortened when the tumour population failed to meet the positivity criterion, i.e. to harbour ligands for the endogenous lectin (P=0.0039 and P=0.0259, respectively). We conclude that (a) studies with an endogenous lectin as a marker are technically feasible and (b) detection of accessible galectin-3-specific ligands is an independent prognostic marker in advanced head and neck squamous cell cancer with therapeutic potential. Of note, histochemical application of an endogenous effector after its purification and labelling may bear relevance beyond the galectins.

Abstract
PURPOSE Tumor uptake of 2-[(18)F] fluoro-2-deoxy-D-glucose (FDG) may relate to outcome in cancer patients. Pretreatment FDG uptake was evaluated as a predictor of local control (LC) and disease-free survival (DFS) in patients with head-and-neck cancer managed primarily either by radiotherapy (RT) or surgery. PATIENTS AND METHODS Tumor FDG uptake using the Standardized Uptake Value (SUV) was measured in 120 patients studied prospectively using positron emission tomography (PET). Treatment consisted of either radical RT with or without chemotherapy (73 patients) or radical surgery with or without postoperative RT (47 patients). Median follow-up of the surviving patients was 48 months. RESULTS The median SUV was higher in 46 patients who failed treatment than in the remaining controlled patients (5.8 vs. 3.6, p = 0.002). In monovariate analysis, patients with tumors having high FDG uptake (SUV > median, 4.76) had poorer LC (p = 0.003) and DFS (p = 0.005). This difference was also observed when the RT and surgery groups were analyzed separately. In the multivariate analysis T-category (p = 0.005) and SUV (p = 0.046) remained independent adverse factors for LC, whereas N-category (p = 0.004), T-category (p = 0.02) and SUV (p = 0.05) were independent determinants of DFS. CONCLUSION These results suggest that pretreatment tumor FDG uptake represents an independent prognostic factor in patients with head-and-neck cancers, whatever the primary treatment modality. Tumors having high FDG uptake are at greater risk of failure and should be considered for more aggressive multimodality therapy.

Abstract
Two protooncogene products, EGFR (Her-1, c-erbB-1) and HER2 (Her-2/neu, c-erbB-2), have been reported to be frequently overexpressed in head and neck squamous cell carcinoma (HNSCC). In order to identify patients who may benefit from targeted cancer treatment for these two molecules, we determined the expression status of EGFR and HER2 in 129 HNSCC tumor specimens. Two pharmacodiagnostic kits (EGFR pharmDx and HercepTest) were used to identify HNSCC tumors that overexpress EGFR or HER2. Overexpression of EGFR was detected in 42.6% of the tumor specimens, while HER2 was only rarely expressed (overexpression was observed in just 3.1% of all cases). Given the necessity of new therapeutic modalities for patients suffering from HNSCC, treatment EGFR signaling inhibitors appears to be warranted, whereas therapeutic intervention with HER2 inhibitors seems to be inappropriate in this tumor type.

Abstract
The prognostic significance of extracapsular spread of cervical metastases in oral cancer is still controversial. To investigate the importance of extent of extracapsular spread; the relationship between extracapsular spread and both traditional measures of metastatic disease and clinical/histological features of the primary tumour, and to determine their relative prognostic significance. The survival of 173 patients undergoing radical surgery and simultaneous neck dissection for oral/oropharyngeal squamous cell carcinoma with histologically confirmed nodal metastasis and followed for 2.2-12.3 years is reported and related to pathological features. The most predictive clinical/histopathological features were determined by Cox regression modelling. The 3-year survival probability was similar for patients with macroscopic and only microscopic extracapsular spread (33 and 36%, respectively, compared with 72% for patients with intranodal metastasis). The Cox model showed the most predictive factor was extracapsular spread followed by status of resection margins. Extracapsular spread should be incorporated into pathological staging systems. Even microscopic extracapsular spread is of critical importance and must be sought especially in small-volume metastatic disease.

Abstract
PURPOSE In patients with head and neck cancer enrolled onto a prospective study of positron emission tomography (PET), pretreatment 2-[(18)F] fluoro-2- deoxy-D-glucose (FDG) uptake was evaluated as a predictor of local control and disease-free survival (DFS) after treatment by radiotherapy (RT) with or without chemotherapy. PATIENTS AND METHODS We studied 63 patients with carcinomas of the head and neck who had an FDG-PET scan before radical RT. Tumor FDG uptake was measured with the semiquantitative standardized uptake value (SUV). All patients but one were treated with accelerated or hyperfractionated RT schedules. Thirteen patients received concomitant cisplatin-based chemotherapy. RESULTS In 25 patients who presented with any component of treatment failure, the SUV was significantly higher than in the remaining patients without any such failure. Patients having tumors with high FDG uptake had a significantly lower 3-year local control (55% v 86%, P =.01) and DFS (42% v 79%, P =.005) compared with patients having low uptake tumors. In the multivariate analysis, the only factor that retained its significance for DFS was SUV category, whereas T category was of borderline significance. For local control, T category remained a significant factor, whereas a lower local control was observed for tumors with a high SUV compared with those with low SUV. CONCLUSION FDG uptake, as measured by the SUV, has potential value in predicting local control and DFS in head and neck carcinomas treated by RT. High FDG uptake may be a useful parameter for identifying patients requiring more aggressive treatment approaches.

Abstract
The prognosis for patients with squamous carcinomas of the head and neck region is strongly influenced by the presence or absence of cervical lymph node metastases. Biological markers that indicated a high risk of metastasis would have a major role in determining the optimal therapeutic strategy for these patients. This editorial discusses recent studies of molecular and genetic markers of squamous carcinomas in relation to metastatic potential and highlights some of the issues that limit current progress in this field of study.

Abstract
The proto-oncogene products erbB-l (EGF-Receptor) and erbB-2 (HER-2/neu), distinct members of the epidermal growth factor receptor family, are frequently overexpressed in squamous cell carcinoma of the head and neck (SCCHN). The accumulation of these transmembrane proteins may lead to significant amounts of the respective extracellular receptor domains (ECD) that are shed from the tumour cell surface and enter blood circulation, thus representing potential serum tumour markers. For erbB-l and erbB-2, we determined the ECD serum levels with enzyme-linked immunosorbent assays and evaluated the protein expression in tumour tissue by immunohistochemistry. The present study included 49 patients (37 untreated, 12 recurrences) and the same number of age- and sex-matched healthy controls. In 24 patients ECD serum levels were determined before and 6 weeks after surgery. Mean ECD serum levels for erbB-1 and erbB-2 were 54.8+/-1.6 and 153.7+/-6.1 fmol/ml in cancer patients, and 54+/-1.5 and 147.9+/-4.5 fmol/ml in healthy controls, respectively. There was no significant difference between untreated and recurrent disease. Serum ECD follow-ups 6 weeks after surgery revealed a significant 12.3% decline of erbB-1 but no change of erbB-2 values. Immunohistochemistry showed strong staining for erbB-1 in 78% and erbB-2 in 47% of the SCCHN specimens. No correlation was detectable between receptor ECD serum levels and receptor tissue expression, tumour stage, and tumour differentiation. Hence, ECD serum levels of erbB-1 and erbB-2 are not considered to be valuable tumour markers in SCCHN.

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.
