Abstract
Optical spectroscopy is studied to contribute to skin cancer diagnosis. Indeed, optical spectra are modified along cancer progression and provide complementary information (e.g., on metabolism and tissue structure) to clinical examination for surgical guidance [1,2]. The current original dataset is made of autofluorescence and diffuse reflectance spectra acquired in vivo on 131 patients' skin with the SpectroLive device [3,4]. Spatially-resolved spectroscopy measurements were performed using a multi-fiber optic probe featuring 4 distances (0.4-1 mm) between excitation and collection optical fibers: spatial resolution allows spectra acquired at different distances to carry information from different depths in skin tissues. Five types of autofluorescence spectra were acquired using five different wavelength excitations (on the 365-415 nm spectral range) in order to collect information on several skin endogenous fluorophores (e.g., flavins, collagen). A sixth light source (white broadband) was used to acquire diffuse reflectance spectra carrying information about skin scattering properties and skin endogenous absorbers such as melanin and hemoglobin. Patients were proposed to be included into the clinical trial if they were suspected of suffering from actinic keratoses (precancerous skin lesions) or from basal or squamous cell carcinomas: in all cases, complete diagnostics is provided in the dataset. To increase the interest of the dataset and evaluate the dependence of optical spectra (intensity, shape) not only on pathological states but also on healthy skin features (civil age, skin age, gender, phototype, anatomical site), spectra were acquired for all 131 patients on two so-called "reference" skin sites known to rarely suffer from skin cancer: palm of the hand (featuring a thick skin type) and inner wrist (featuring thin skin). Spectra are available in .tab files: first column displays the spectral range on which intensity spectra were recorded (317-788 nm) and each following column provides an intensity spectrum acquired by each spectrometer for a given combination of light source excitation and distance. Each of the 131 folders corresponding to each of the 131 patients contains a .json file providing patients clinical features: gender, civil age, skin age, phototype score and class. All .tab files names include anatomical site and anatomopathological diagnostics of the skin site on which spectra were acquired: codes were defined to match a letter or an acronym to each diagnostic and anatomical site. To ensure quality control, a spectrum was acquired on the same calibration standard before starting spectra acquisition on each patient. It is therefore possible to follow the impact of the acquisition optical chain ageing during the 4.5 years that the patients were included. This dataset can be used by epidemiologists for the characterization of populations affected by skin cancers (gender ratio, mean age, anatomical sites typically affected, etc.); it may also be used by researchers in artificial intelligence to develop innovative methods to process such data and contribute to non-invasive diagnostics of skin cancers whose incidence is steadily increasing.

Abstract
Lip and oral cavity SCC account for 2nd highest incidence of cancers and 3rd most common cause of mortality from cancer in India. Reconstruction of defects of central arch invading cancers results in poor cosmetic and functional outcomes if free flaps are not used. 30 patients with Oral SCC in the age group 20-75 years requiring central arch segmental mandibulectomy were included. Reconstruction was done with pedicled bipaddled PMMC flap with 'AJ's orbicularis oris stitch' using Fiber wire. Patients were divided into 4 groups according to extent of lip and skin loss post excision of primary tumour. Patients were evaluated with subjective scores for drooling, oral competence and cosmesis. There were 4, 12, 9 and 5 patients in Group A, B, C and D respectively. Mean subjective scores using our technique for drooling, oral competence and cosmesis were 3.75/4,3.75/4 and 3.5/4 for group A, 3.45/4, 3.36/4 and 3.09/4 for group B, 2.8/4, 2.6/4 and 2.3/4 for group C defects and 2.5/4, 3/4 and 2.5/4 for group D defects respectively. Over all scores for all patients were 3.2/4, 3.14/4 and 2.84/4 for drooling, oral competence and cosmesis. This simple, quick and inexpensive technique of reconstruction of central mandibular arch defects can drastically improve cosmetic and functional outcomes in a resource restrained set up. However, long term results and comparison studies are required for standardisation of the technique.

Abstract
Multidrug resistance renders treatment failure in a large proportion of head and neck squamous cell carcinoma (HNSCC) patients that require multimodal therapy involving chemotherapy in conjunction with surgery and/or radiotherapy. Molecular events conferring chemoresistance remain unclear. Through transcriptome datamining, 28 genes were subjected to pharmacological and siRNA rescue functional assays on 12 strains of chemoresistant cell lines each against cisplatin, 5-fluorouracil (5FU), paclitaxel (PTX) and docetaxel (DTX). Ten multidrug chemoresistance genes (TOP2A, DNMT1, INHBA, CXCL8, NEK2, FOXO6, VIM, FOXM1B, NR3C1 and BIRC5) were identified. Of these, four genes (TOP2A, DNMT1, INHBA and NEK2) were upregulated in an HNSCC patient cohort (n = 221). Silencing NEK2 abrogated chemoresistance in all drug-resistant cell strains. INHBA and TOP2A were found to confer chemoresistance in majority of the drug-resistant cell strains whereas DNMT1 showed heterogeneous results. Pan-cancer Kaplan-Meier survival analysis on 21 human cancer types revealed significant prognostic values for INHBA and NEK2 in at least 16 cancer types. Drug library screens identified two compounds (Sirodesmin A and Carfilzomib) targeting both INHBA and NEK2 and re-sensitised cisplatin-resistant cells. We have provided the first evidence for NEK2 and INHBA in conferring chemoresistance in HNSCC cells and siRNA gene silencing of either gene abrogated multidrug chemoresistance. The two existing compounds could be repurposed to counteract cisplatin chemoresistance in HNSCC. This finding may lead to novel personalised biomarker-linked therapeutics that can prevent and/or abrogate chemoresistance in HNSCC and other tumour types with elevated NEK2 and INHBA expression. Further investigation is necessary to delineate their signalling mechanisms in tumour chemoresistance.

Abstract
Oropharyngeal squamous cell carcinomas (OPSCC) represent a major public health challenge. In 2020, the international agency for research on cancer (IARC) recorded 98,421 cases of OPSCC worldwide. Over the past decade, the epidemiological profile of patients with OPSCC has shifted, mainly due to a change in etiological factors. Previously, alcohol and tobacco were considered the primary contributors, but the human papillomavirus (HPV) is now recognized as the leading cause of these tumors. This study aimed to conduct a literature review on the relationship between OPSCC and HPV for the general practitioner. The review examined the primary clinical differences between HPV+ and HPV- OPSCC, their prognosis and treatment. In addition, the various HPV diagnostic methods were analyzed. Although there is a vast amount of literature on HPV, this review is unique in its ability to present the key information in an organized and accessible way and enables healthcare professionals to gain a better understanding of the relationship between HPV and oropharyngeal cancer. This, in turn, can contribute to the prevention of various cancers caused by the HPV virus, including oropharyngeal cancer.

Abstract
Background Primary parotid squamous cell carcinoma (SCC) is a rare entity with a poor prognosis. Pathologically, the diagnosis of it requires the exclusion of parotid mucoepidermoid carcinoma (MEC). Currently, the imaging features of primary parotid SCC and the predictive indicators for differential diagnosis of the two entities have not been well reported. Our purpose was to identify the imaging characteristics of primary parotid SCC and to determine the predictive factors for its’ differential diagnosis. Results Thirty-one participants with primary parotid SCC and 59 with primary parotid MEC were enrolled. Clinical, CT and MRI features were reviewed and compared by univariate analysis. Then, multinomial logistic regression was used to determine the predictors to distinguish parotid SCC from MEC. Most primary parotid SCCs exhibited irregular shape, ill-defined margin, incomplete or no capsule, heterogeneous and marked or moderate enhancement, necrosis, local tumor invasiveness (LTI). Age, maximal dimension, shape, degree of enhancement, gradual enhancement, necrosis, and LTI were different between the primary parotid SCCs and MECs in univariate analysis (p < 0.05). While in multinomial logistic regression analysis, only age and necrosis were the independent predictors for distinguishing parotid SCC from MEC, and this model exhibited an area under curve of 0.914 in ROC curve analysis. Conclusions Primary parotid SCC has some distinct imaging features including the large tumor size, irregular shape, ill-defined margin, and particularly the marked central necrosis. Patients with age ≥ 51.5 years and necrosis on the image of the primary tumor in the parotid gland could be more likely to be SCCs than MECs.

Abstract
OBJECTIVE Human papillomavirus (HPV) gained momentum as a potential etiological factor for many types of cancers. Therefore, the aim of this study was to assess the prevalence of HPV-16 infection among Sudanese patients diagnosed with Squamous Cell Carcinoma (SCC) and Salivary Gland Carcinoma. A descriptive, hospital-based study was conducted. 150 formalin-fixed paraffin-embedded blocks were collected. RESULTS The study population included a total of 150 patients aged between 18 to 87 years with a mean age of 48.8 ± 11.9 years. Based on gender, females constituted 46.7% while males constituted 53.3%. The 150 patients were classified into 40 (26.0%) esophageal, 30 (20.0%) nasopharyngeal, 18 (12.0%) conjunctival, 18 (12.0%) tongue 12 (8.0%) laryngeal, 8 (5.3%) lip, 6 (4.0%) oropharyngeal, 6 (4.0%) mucoepidermoid, and 6 (4.0%) adenoid cystic, and 6 (4.0%) myoepithelial carcinomas. Odds ratio for male and female diagnosed with carcinoma was 1.025 [0.439-2.394, 95% CI]. Molecular detection of HPV-16 revealed a prevalence of 26 (17.3%) patients were positive for HPV-16. According to cancer diagnosis, esophageal SCC patients showed a high proportion of HPV-16; 14/40 (35.0%). A statistically significant difference was seen for the distribution of HPV-16 positive patients based on cancer diagnosis, P value 0.001.

Abstract
Giant squamous cell carcinomas (SCC) larger than 5 cm in diameter are uncommon; there is no guideline on the size of an SCC that is considered giant. Treatment may be difficult with the need for large tissue resections and complex surgical reconstruction. We report a rare case of giant squamous cell carcinoma of the shoulder attached to deep anatomic planes. The entire mass was removed, resulting in a large defect that was repaired with myocutaneous flap rotation of the latissimus dorsi. Three courses of radiotherapy were performed after surgery. Fifteen months after the operation, the patient is well and working without any local recurrence and metastasis.

Abstract
OBJECTIVES To investigate MRI features in discriminating chronic invasive fungal rhinosinusitis (CIFRS) from sinonasal squamous cell carcinomas (SNSCC). METHODS MRI findings of 33 patients with CIFRS and 47 patients with SNSCC were retrospectively reviewed and compared. Multivariate logistic regression analysis was performed to identify significant imaging features in distinguishing between CIFRS and SNSCC. The ROC curves and the AUC were used to evaluate diagnostic performance. RESULTS There were significant differences in cavernous sinus involvement (p < 0.001), sphenoid sinus involvement (p < 0.001), meningeal involvement (p = 0.024), T2 signal intensity (p = 0.006), and enhancement pattern (p < 0.001) between CIFRS and SNSCC. Multivariate logistic regression analysis identified cavernous sinus involvement (odds ratio [OR] = 0.06, 95% confidence interval [95% CI] = 0.02-0.20) and sphenoid sinus involvement (OR = 0.14, 95% CI = 0.05-0.45) as significant indicators for CIFRS and T2 isointensity to gray matter (OR = 4.44, 95% CI = 1.22-16.22) was a significant indicator for SNSCC. ROC curve analysis showed the AUC from a combination of three imaging features was 0.95 in differentiating CIFRS and SNSCC. CONCLUSIONS MRI showed significant differences between CIFRS and SNSCC features. In immunocompromised patients, a sinonasal hypointense mass on T2WI with septal enhancement or loss of contrast enhancement, and involvement of cavernous sinus, sphenoid sinus, and meninges strongly suggest CIFRS. KEY POINTS • Chronic invasive fungal rhinosinusitis (CIFRS) is often difficult to distinguish from sinonasal squamous cell carcinomas (SNSCC) in clinical practice. • Cavernous sinus and sphenoid sinus involvement appear to be significant indicators for CIFRS. T2 isointensity to gray matter appears to be a significant indicator for SNSCC. • Loss of contrast enhancement and septal enhancement can be used to distinguish CIFRS from SNSCC with a high degree of specificity.

Abstract
Cancer hijacks embryonic development and adult wound repair mechanisms to fuel malignancy. Cancer frequently originates from de-regulated adult stem cells or progenitors, which are otherwise essential units for postnatal tissue remodeling and repair. Cancer genomics studies have revealed convergence of multiple cancers across organ sites, including squamous cell carcinomas (SCCs), a common group of cancers arising from the head and neck, esophagus, lung, cervix and skin. In this review, we summarize our current knowledge on the molecular drivers of SCCs, including these five major organ sites. We especially focus our discussion on lineage dependent driver genes and pathways, in the context of squamous development and stratification. We then use skin as a model to discuss the notion of field cancerization during SCC carcinogenesis, and cancer as a wound that never heals. Finally, we turn to the idea of context dependency widely observed in cancer driver genes, and outline literature support and possible explanations for their lineage specific functions. Through these discussions, we aim to provide an up-to-date summary of molecular mechanisms driving tumor plasticity in squamous cancers. Such basic knowledge will be helpful to inform the clinics for better stratifying cancer patients, revealing novel drug targets and providing effective treatment options.

Abstract
OBJECTIVES This study aimed to explore the value of preoperative radiotherapy in the comprehensive treatment of locally advanced nasal cavity and paranasal sinus squamous cell carcinomas (LA-NPSCCs). MATERIALS This retrospective study included 140 patients with stage III-IVB NPSCCs treated with pre-/postoperative radiotherapy plus surgery. The complete resection rate, pathologic complete response (pCR) rate, and orbital content retention rate were calculated. The overall survival (OS), local control (LC), distance metastasis free survival (DMFS) and disease-free survival (DFS) between treatment groups were evaluated. RESULTS With a median follow-up of 92.3 months, the 5-year OS, LC, DMFS, and DFS of entire cohort were 62.0%, 65.5%, 85.4%, and 57.8%, respectively. The preoperative radiotherapy group achieved similar LC, DFS, DMFS, and OS rates compared to postoperative radiotherapy group, despite higher rates of stage IV and orbital content/apex invasion. The preoperative radiotherapy resulted in significantly improved complete resection rate (93.3% vs 38.0%, p < 0.001). In the preoperative radiotherapy group, one third of patients achieved pathologic complete response. The pCR subgroup achieved statistically higher 5-year OS, LC, DFS (p < 0.05), but similar 5-year DMFS (p > 0.05) compared to non-pCR subgroup. The actual orbital content retention rate in preoperative radiotherapy group was 85.7%, superior to 58.3% in postoperative radiotherapy group (p = 0.049). CONCLUSION On the basis of multimodality therapy becoming standard paradigm for LA-NPSCCs, preoperative radiotherapy significantly improved complete resection rate and orbital content retention rate. Therefore, preoperative radiotherapy followed by surgery might be desirable for LA-NPSCCs, especially for those with organ preservation intention.

Abstract
PURPOSE To compare radiotherapy treatments plans in esophageal cancer calculated for a high-field magnetic resonance imaging (MRI)-linac with plans for a conventional linac. MATERIALS AND METHODS Ten patients with esophageal squamous cell carcinomas were re-planned retrospectively using the research version of Monaco (V 5.19.03, Elekta AB, Stockholm, Sweden). Intensity modulated radiotherapy (IMRT) plans with a nine-field step-and-shoot technique and two-arc volumetric modulated arc therapy (VMAT) plans were created for the Elekta MRI-linac and a conventional linac, respectively. The prescribed dose was 60 Gy to the primary tumor (PTV60) and 50 Gy to elective volumes (PTV50). Plans were optimized for optimal coverage of the 60 Gy volume and compared using dose-volume histogram parameters. RESULTS All calculated treatment plans met predefined criteria for target volume coverage and organs at risk dose both for MRI-linac and conventional linac. Plans for the MRI-linac had a lower number of segments and monitor units. No significant differences between both plans were seen in terms of V20Gy of the lungs and V40Gy of the heart with slightly higher mean doses to the heart (14.0 Gy vs. 12.5 Gy) and lungs (12.8 Gy vs. 12.2 Gy). CONCLUSION Applying conventional target volume and margin concepts as well as dose-fractionation prescription reveals clinically acceptable dose distributions using hybrid MRI-linac in its current configuration compared to standard IMRT/VMAT. This represents an important prerequisite for future studies to investigate the clinical benefit of MRI-guided radiotherapy exploiting the conceptional advantages such as reduced margins, plan adaptation and biological individualization and hypofractionation.

Abstract
In comparison with other tumor entities there is no common generally accepted grading system for lung cancer with clearly defined criteria and clinical relevance. In the recent fourth edition of the World Health Organization (WHO) classification from 2015 of tumors of the lungs, pleura, thymus and heart, there is no generally applicable grading for pulmonary adenocarcinomas, squamous cell carcinomas or rarer forms of carcinoma. Since the new IASLC/ATS/ERS classification of adenocarcinomas published in 2011, 5 different subtypes with significantly different prognosis are proposed. This results in an architectural (histologic) grading, which is usually applied to resection specimens. For squamous cell carcinoma the number of different histological subtypes in the new WHO classification was reduced compared to earlier versions but without a common grading system. In recent publications nesting and budding were proposed as the main (histologic) criteria for a grading of squamous cell carcinomas. The grading of neuroendocrine tumors (NET) of the lungs in comparison with NET in other organs is presented in a separate article in this issue. Certain rare tumor types are high grade per definition: small cell, large cell and pleomorphic carcinomas, carcinosarcomas and pulmonary blastomas. In the future it is to be expected that these developments will be further refined, e. g. by adding further subtypes for adenocarcinomas and cytologic and/or nuclear criteria for adenocarcinoma and/or squamous cell carcinomas.

Abstract
Protein kinase C delta (PKC-δ) has been identified as a tumor suppressor. However, the effects of PKC-δ on the cancer stem cells in squamous cell carcinomas (SCC) have not been clarified. The purpose of this study was to detect the regulation of PKC-δ on cancer stem cell among SSC cells and the role of p63 during the regulation. Immunohistochemistry of human cutaneous SCC tissues was performed to detect the expression of PKC-δ. After the human SCC13 cells infected by recombinant adenoviruses, the cell proliferation were determined. The correlation of PKC-δ and p63 was detected by western blot. The colony forming activity and the number of cancer stem cells (CSCs) in SCC identified by double-staining with anti-integrin α6 and anti-CD71 antibodies were detected. The expression of PKC-δ was obviously decreased in SCC tissues compared with that in normal skin tissues. The higher protein level of p63 in SCC was attenuated by the transfection of PKC-δ. The higher proliferation capacity of SCC13 cells, the higher activity and expression of CSCs in SCC13 cells induced by p63 were significantly suppressed by the transfection of PKC-δ. In conclusion, PKC-δ played as a protective role in SCC partly by down-regulating p63, leading to the suppression of SCC cell proliferation, attenuation of the activity and expression of CSCs in SCC cells.

Abstract
OBJECTIVE To clarify risk factors for rare vulvar neoplasms. METHODS Within the NIH-AARP Study, among 201,469 women interviewed in 1995-1996 and followed for a mean of 13.8years, there were 370 diagnoses of incident vulvar neoplasms, including 170 invasive and 198 vulvar intraepithelial neoplasms grade 3 (VIN3). Hazard ratios (HR) and 95% confidence intervals (CI) were calculated via multivariate logistic regression for various demographic, reproductive and lifestyle factors, with separate consideration of relations according to invasiveness, histology and age at diagnosis. RESULTS Consistent with descriptive data, we found non-white women at lower risks of vulvar neoplasia than white women (HR=0.59, 95% CI 0.36-0.95). Significant risk factors for VIN3 included being divorced/separated (HR vs. currently married=1.77, 95% CI 1.24-2.51), a current cigarette smoker (3.88, 95% CI 2.64-5.72), a user of oral contraceptives (1.46, 95% CI 1.06-2.01), or a current user of menopausal hormones (1.73, 95% CI 1.24-2.41). Significant risk factors for invasive cancers were being obese (HR for BMI ≥30 vs. <25=1.62, 95% CI 1.10-2.40) or a current smoker (1.86, 95% CI 1.21-2.87). Cigarette smoking was a risk factor mainly for neoplasms shown in other investigations to be HPV-related, namely VIN3 and invasive squamous cell cancers (SCCs) occurring in the younger stratum of cases. In contrast, obesity was primarily associated with the development of invasive SCCs. CONCLUSIONS Our results support that vulvar neoplasia is a heterogeneous disease. VIN3 demonstrated risk factors consistent with an HPV-related etiology, while invasive cancers were additionally affected by obesity, suggesting that further attention should focus on the role of chronic inflammatory conditions.

Abstract
Quoique rare le carcinome épidermoïde du scrotum a un mauvais pronostic. Les Carcinomes du scrotum induite et - liées au travail sont moins fréquentes en raison d'une meilleure hygiène, vêtements de protection, et la sensibilisation de la cancérogénicité des huiles industrielles. L’épidémie à l'HPV a induit une augmentation de l'incidence. Le traitement de dépend toujours exérèse locale de la lésion primaire. La radiothérapie a peu de bénéfice thérapeutique dans le traitement d'un carcinome épidermoïde du scrotum. La bléomycine peut être utile comme traitement adjuvant pour les maladies ilio-inguinal généralisée avant la tentative exérèse, même si cela n'a pas encore été prouvé. Entre janvier 2011 au 1er janvier 2013, 7 patients atteints de carcinome épidermoïde ont été pris en charge, Trois patients ont présenté une localisation ganglionnaire. Les sept patients ont eu un traitement chirurgical par exérèse large avec reconstruction, Deux patients ont été adressé pour chimiothérapie.2 patients ont présenté une récidive, dont un est décédé.

Abstract
Head and neck squamous cell carcinoma is the sixth most common cancer worldwide predominately associated with tobacco use. Changing cause and increased incidence in oropharyngeal carcinomas is associated with high-risk types of human papilloma virus and has an improved survival. Optical devices may augment visual oral examination; however, their lack of specificity still warrants tissue evaluation/biopsy. Histologic factors of oral carcinomas are critical for patient management and prognostic determination. Clinical biomarkers are still needed to improve early detection, predict malignant transformation, and optimize therapies.

Abstract
Keratoacanthomas (KAs) and cutaneous squamous cell carcinomas (cuSCCs) develop in 15-30% of patients with BRAF(V600E) metastatic melanoma treated with BRAF inhibitors (BRAFi). These lesions resemble mouse skin tumors induced by the two-stage DMBA/TPA skin carcinogenesis protocol; in this protocol BRAFi accelerates tumor induction. Since prior studies demonstrated cyclooxygenase 2 (COX-2) is necessary for DMBA/TPA tumor induction, we hypothesized that COX-2 inhibition might prevent BRAFi-accelerated skin tumors. Celecoxib, a COX-2 inhibitor, significantly delayed tumor acceleration by the BRAFi inhibitor PLX7420 and decreased tumor number by 90%. Tumor gene expression profiling demonstrated that celecoxib partially reversed the PLX4720-induced gene signature. In PDV cuSCC cells, vemurafenib (a clinically approved BRAFi) increased ERK phosphorylation and soft agar colony formation; both responses were greatly decreased by celecoxib. In clinical trials trametinib, a MEK inhibitor (MEKi) increases BRAFi therapy efficacy in BRAF(V600E) melanomas and reduces BRAFi-induced KA and cuSCC frequency. Trametinib also reduced vemurafenib-induced PDV soft agar colonies, but less efficiently than celecoxib. The trametinb/celecoxib combination was more effective than either inhibitor alone. In conclusion, celecoxib suppressed both BRAFi-accelerated skin tumors and soft-agar colonies, warranting its testing as a chemopreventive agent for non-melanoma skin lesions in patients treated with BRAFi alone or in combination with MEKi.

Abstract
OBJECTIVE(S) To investigate the expression of human papilloma virus (HPV) L1 capsid protein, and human telomerase RNA component (hTERC) in cervical cancer and the role of detection of both genes in screening of cervical cancer. MATERIALS AND METHODS A total of 309 patients were recruited and cervical exfoliated cells were collected. Immunocytochemistry was employed to detect HPV L1 capsid protein, and fluorescent in situ hybridization (FISH) was performed to detect the hTERC. RESULTS The expression of HPV L1 capsid protein reduced with the increase of the histological grade of cervical cells and was negatively related to the grade of cervical lesions. However, the expression of hTERC increased with the increase of the histological grade and positively associated with the grade of cervical lesions. The proportion of patients with L1(-)/hTERC(+) was higher in patients with histological grade of CIN2 or higher than that in those with histological grade of CIN1. The L1(+)/hTERC(-) and L1(-)/hTERC(-) were negatively related to the grade of cervical lesions. L1(-)/hTERC(+) was positively associated with the grade of cervical lesions. The L1/hTERC ratio increased. The negative predictive value of both HPV L1 and hTERC was higher than that of HPV L1 or hTERC, but there was no marked difference in the screening efficacy of cervical cancer among HPV L1, hTERC and HPV L1+hTERC. CONCLUSION HPV L1 capsid protein and hTERC gene may serve as markers for the early diagnosis and prediction of cervical lesions. The increase in L1/hTERC ratio reflects the progression of cervical lesions to a certain extent.

Abstract
Sinonasal carcinomas are rare tumours with an unfavourable prognosis whose management is difficult and complex, leading to high morbidity and mortality despite improvements in the field of surgery and radiotherapy. An elevated number of these tumours can be attributed to occupational exposure. In comparison with other head and neck malignancies, studies of molecular changes in these tumours are infrequent. This review was focused on findings about the epidemiology and molecular and phenotypic characterisation of sinonasal carcinomas, which can potentially be useful for diagnosis and treatment. The increasing knowledge about the molecular biology that underlies their carcinogenesis may help to identify precursor lesions, prognostic markers and markers that predict chemoradiotherapy response and, finally, to identify potential molecular targets that will expand treatment options.
