Abstract
BACKGROUND Cutaneous squamous cell carcinoma (cSCC) develops from epithelial keratinocytes by dysregulation of self-renewal and differentiation. Recent studies have found that the size and number of cSCC tumors gradually decrease or even disappear after HPV vaccination. However, the role of the HPV vaccine in the cSCC mechanism is poorly understood. OBJECTIVE The aim of this study is to investigate the effect and mechanism of the HPV vaccine in cSCC. METHODS Immunofluorescence was used to study the immune infiltrating cells in the tumor tissues of patients with cSCC. The effects of the HPV vaccine on cSCC cells and tissues were studied by Cell Culture, Real-time PCR, Western Blot, Cytotoxicity Assay, Enzyme-linked Immunosorbent Assay, m6A Blotting, CCK-8 Assay, m6A Ribonucleic acid Methylation Quantification and tumor transplantation. RESULTS The HPV vaccine enhanced the toxic effect of CD8+T cells on cSCC cells and promoted the secretion of multiple cytokines by CD8+T cells. In addition, HPV vaccines can increase tumor sensitivity to anti-PD-1 therapy by downregulating METTL3 in tumor tissue, with the combination of HPV vaccine and PD-1 monoclonal antibodies producing enhanced immune cell infiltration compared to PD-1 blockade alone. STUDY LIMITATIONS It is important to note the limitations of this study, including the small sample size, the construction of the mouse model, and the choice of HPV vaccine and PD-1 monoclonal antibody, which may limit the generalization of our findings to a wider population. CONCLUSIONS It is hoped that this research will contribute to a deeper understanding of the role of the HPV vaccine in the treatment of cSCC. HPV vaccine is expected to become an important approach to alleviate the development of cSCC.

Abstract
OBJECTIVES A published tumour regression grade (TRG) score for squamous anal carcinoma treated with definitive chemoradiotherapy based on T2-weighted MRI yields a high proportion of indeterminate responses (TRG-3). We investigate whether the addition of diffusion-weighted imaging (DWI) improves tumour response assessment in the early post treatment period. MATERIALS AND METHODS This retrospective observational study included squamous anal carcinoma patients undergoing MRI before and within 3 months of completing chemoradiotherapy from 2009 to 2020. Four independent radiologists (1-20 years' experience) scored MRI studies using a 5-point TRG system (1 = complete response; 5 = no response) based on T2-weighted sequences alone, and then after a 12-week washout period, using a 5-point DWI-TRG system based on T2-weighted and DWI. Scoring confidence was recorded on a 5-point scale (1 = low; 5 = high) for each reading and compared using the Wilcoxon test. Indeterminate scores (TRG-3) from each reading session were compared using the McNemar test. Interobserver agreement was assessed using kappa statistics. RESULTS Eighty-five patients were included (mean age, 59 years ± 12 [SD]; 55 women). T2-weighted TRG-3 scores from all readers combined halved from 24% (82/340) to 12% (41/340) with DWI (p < 0.001). TRG-3 scores changed most frequently (41%, 34/82) to DWI-TRG-2 (excellent response). Complete tumour response was recorded clinically in 77/85 patients (91%). Scoring confidence increased using DWI (p < 0.001), with scores of 4 or 5 in 84% (287/340). Interobserver agreement remained fair to moderate (kappa range, 0.28-0.58). CONCLUSION DWI complements T2-weighted MRI by reducing the number of indeterminate tumour responses (TRG-3). DWI increases radiologist's scoring confidence. CLINICAL RELEVANCE STATEMENT Diffusion-weighted imaging improves T2-weighted tumour response assessment in squamous anal cancer, halving the number of indeterminate responses in the early post treatment period, and increases radiologists' confidence. KEY POINTS Tumour response based on T2-weighted MRI is often indeterminate in squamous anal carcinoma. Diffusion-weighted imaging alongside T2-weighted MRI halved indeterminate tumour regression grade scores assigned by four radiologists from 24 to 12%. Scoring confidence of expert and non-expert radiologists increased with the inclusion of diffusion-weighted imaging.

Abstract
OBJECTIVE To explore the significance and feasibility of whole exon sequencing and immune related indexes in personalized precision treatment of oral squamous cell carcinoma (OSCC). METHODS We retrospectively screened the patients who underwent surgery for oral cancer in Peking University Hospital of Stomatology and underwent genetic and immune biomarkers tests between January 2021 and June 2022. Combined with the clinicopathological characteristics of patients, potential targeted drugs and immunotherapy drugs were screened to evaluate the possibility of gene testing benefiting OSCC. The main evaluation indicators included the number of gene mutations, combined positive score (CPS), tumor mutation burden (TMB), microsatellite sequence status and human leukocyte antigen B (HLA-B) locus. Excel was used for statistical analysis. RESULTS A total of 10 patients were enrolled and 9 were included in this study, including 6 males and 3 females, with an average age of (55.44±9.59) years. The tumor location was buccal (5 cases), tongue (3 cases) and gingival (1 case). The results of genetic testing showed that 3 (33.3%) patients had no gene mutations in the tumor tissue, 5 (55.6%) patients had unique TP53 gene mutations, and 1 (11.1%) patient had TP53 and CHEK1 mutations. However, no drugs were available for targeted therapy of the mutated genes. The genetic tumor gene testing results showed that no genetic tumor gene was found in all the patients, suggesting that OSCC had a low possibi-lity of hereditary tumor. In terms of immune efficacy related markers, CPS test results showed that 8 patients had CPS≥1. TMB detection results showed that the median value of TMB value was 0.72 mutations/Mb, and the range was 0 to 4.32 mutations/Mb. The negative and positive control results of microsatellite sequence status were consistent, indicating that all the tumor tissues detected were microsatellite stability. The results of HLA-B detection showed that only one patient had B62 gene mutation, suggesting that the B44 and B62 related genotypes of HLA-B in OSCC tissue samples were low. CONCLUSION The present results do not support the wide application and promotion of genetic testing and immune related indexes in OSCC.

Abstract
PURPOSE The 8th edition of the TNM Cancer Staging Manual incorporates depth of invasion (DOI) into the pathologic tumor classification for oral squamous cell carcinoma (OSSC). While deep invading tumors with small tumor diameters (TD) have been categorized as early stage tumors in the 7th edition, they are now upstaged, potentially influencing the decision to initiate adjuvant radiotherapy (RT). METHODS OSCC patients surgically treated with curative intent between 2010 and 2019 were consecutively included. Tumors were staged based on TD only (according to the 7th edition TNM Cancer Staging Manual), then restaged based solely on DOI. RESULTS Of the 133 included patients, 58 patients (43.6%) had a different pT-stage when using DOI instead of TD for staging (upstaging in 23.3%). Overall survival (OS) was significantly worse in patients who were upstaged with DOI. In addition, stratification by adjuvant RT showed significant worse OS in upstaged patients without receiving adjuvant RT. CONCLUSIONS DOI seems to be an import indicator for adjuvant RT in OSCC-patients.

Abstract
BACKGROUND Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer (sqNSCLC) after failure of first-line chemotherapy are limited. This study (ORIENT-3) aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC. METHODS ORIENT-3 was an open-label, multicenter, randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy. Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m2 of docetaxel intravenously every 3 weeks, stratified by the Eastern Cooperative Oncology Group performance status. The primary endpoint was overall survival (OS) in the full analysis set (FAS). Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), duration of response (DoR) and safety. RESULTS Between August 25, 2017, and November 7, 2018, 290 patients were randomized. For FAS, 10 patients from the docetaxel arm were excluded. The median OS was 11.79 (n = 145; 95% confidence interval [CI], 10.28-15.57) months with sintilimab versus 8.25 (n = 135; 95% CI, 6.47-9.82) months with docetaxel (hazard ratio [HR]: 0.74; 95% CI, 0.56-0.96; P = 0.025). Sintilimab treatment significantly prolonged PFS (median 4.30 vs. 2.79 months; HR: 0.52; 95% CI, 0.39-0.68; P < 0.001) and showed higher ORR (25.50% vs. 2.20%, P < 0.001) and DCR (65.50% vs. 37.80%, P < 0.001) than the docetaxel arm. The median DoR was 12.45 (95% CI, 4.86-25.33) months in the sintilimab arm and 4.14 (95% CI, 1.41-7.23) months in the docetaxel arm (P = 0.045). Treatment-related adverse events of grade ≥ 3 were reported in 26 (18.1%) patients in the sintilimab arm and 47 (36.2%) patients in the docetaxel arm. Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors, including OVOL2 (HR: 0.35; P < 0.001) and CTCF (HR: 3.50; P < 0.001),for sintilimab treatment. CONCLUSIONS Compared with docetaxel, sintilimab significantly improved the OS, PFS, and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC.

Abstract
OBJECTIVE The aim of the present study was to analyze the prognostic relationship of weight loss and preoperative hematological indexes in patients surgically treated for pT4a squamous cell carcinoma of the oral cavity. METHODS A retrospective cohort study. RESULTS Percent weight loss greater than 10% was identified in 49 patients (28.2%), and any weight loss in relation to the usual weight occurred in 140 patients (78.7%). Percent weight loss greater than 10% (HR = 1.679), Red cell distribution width (RDW) values greater than 14.3% (HR = 2.210) and extracapsular spread (HR = 1.677) were independent variables associated with risk of death. CONCLUSION Patients with advanced squamous cell carcinoma of the oral cavity present significant weight loss and as significantly immunocompromised. Increased values of RDW and higher percentages of weight loss in relation to the individual's usual weight, together with extracapsular spread of metastatic lymph nodes, were risk factors for lower survival, regardless of other clinical and anatomopathological characteristics.

Abstract
Oral cancer could be prevented. The primary strategy is based on prevention. Most patients with oral cancer present to the hospital network with advanced staging and a low chance of cure. This condition may be related to physicians' difficulty of making an early diagnosis. With the advancement of information technology, artificial intelligence (AI) holds great promise in terms of assisting in diagnosis. Few machine learning algorithms have been developed for this purpose to date. In this paper, we will discuss the possibilities for diagnosing oral cancer using AI as a tool, as well as the implications for the population. A set of photographic images of oral lesions has been segmented, indicating not only the area of the lesion but also the class of lesion associated with it. Different neural network architectures were trained with the goal of fine segmentation (pixel by pixel), classification of image crops, and classification of whole images based on the presence or absence of a lesion. The accuracy results are acceptable, opening up possibilities not only for identifying lesions but also for classifying the pathology associated with them.

Abstract
OBJECTIVES To assess the effectiveness of fluorine-18 fluorodeoxyglucose (FDG) positron-emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) for response assessment post curative-intent chemoradiotherapy (CRT) in anal squamous cell carcinoma (ASCC). METHODS Consecutive ASCC patients treated with curative-intent CRT at a single centre between January 2018 and April 2020 were retrospectively identified. Clinical meta-data including progression-free survival (PFS) and overall survival (OS) outcomes were collated. Three radiologists evaluated PET-CT and MRI using qualitative response assessment criteria and agreed in consensus. Two-proportion z test was used to compare diagnostic performance metrics (sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), accuracy). Kaplan-Meier analysis (Mantel-Cox log-rank) was performed. RESULTS MRI (accuracy 76%, PPV 44.8%, NPV 95.7%) and PET-CT (accuracy 69.3%, PPV 36.7%, NPV 91.1%) performance metrics were similar; when combined, there were statistically significant improvements (accuracy 94.7%, PPV 78.9%, NPV 100%). Kaplan-Meier analysis demonstrated significant differences in PFS between responders and non-responders at PET-CT (p = 0.007), MRI (p = 0.005), and consensus evaluation (p < 0.001). Cox regression analysis of PFS demonstrated a lower hazard ratio (HR) and narrower 95% confidence intervals for consensus findings (HR = 0.093, p < 0.001). Seventy-five patients, of which 52 (69.3%) were females, with median follow-up of 17.8 months (range 5-32.6) were included. Fifteen of the 75 (20%) had persistent anorectal and/or nodal disease after CRT. Three patients died, median time to death 6.2 months (range 5-18.3). CONCLUSION Combined PET-CT and MRI response assessment post-CRT better predicts subsequent outcome than either modality alone. This could have valuable clinical benefits by guiding personalised risk-adapted patient follow-up. KEY POINTS • MRI and PET-CT performance metrics for assessing response following chemoradiotherapy (CRT) in patients with anal squamous cell carcinoma (ASCC) were similar. • Combined MRI and PET-CT treatment response assessment 3 months after CRT in patients with ASCC was demonstrated to be superior to either modality alone. • A combined MRI and PET-CT assessment 3 months after CRT in patients with ASCC has the potential to improve accuracy and guide optimal patient management with a greater ability to predict outcome than either modality alone.

Abstract
BACKGROUND Secondary malignancies of the parotid gland frequently have a cutaneous origin and the incidence in central Europe is increasing. OBJECTIVE The aim of this review article was to present the epidemiology, (differential) diagnostics and treatment of secondary malignancies of the parotid gland. MATERIAL AND METHODS A literature search of the current guidelines and evidence was carried out in the web-based databank PubMed. RESULTS The incidence of secondary malignancies of the parotid gland seems to be increasing in Europe, mainly due to a rising incidence of metastases of cutaneous squamous cell carcinomas. Except for malignant lymphomas, parotidectomy is the treatment of choice in the curative situation. In the absence of clear evidence, in the case of an intact facial nerve lateral or total parotidectomy with ipsilateral neck dissection seems to be indicated, depending on the entity of the secondary malignancy. CONCLUSION The differential diagnostics of squamous cell carcinoma (in) of the parotid gland can be complicated. When a squamous cell carcinoma of the parotid gland is diagnosed for the first time, a dermatological full body examination and a detailed medical history should be taken with respect to skin tumors of the head and neck region. In addition to surgical treatment of the parotid gland and neck, adjuvant radiotherapy is usually indicated.

Abstract
1,25(OH)2 D3 , the active form of vitamin D, has been extensively studied for its putative protective activities against tumors. It does biological work by connecting to a nuclear receptor called VDR, which heterodimerizes itself to another nuclear receptor, RXR. The study observed differences in VDR and RXR expression in nonmelanoma skin cancer and actinic keratosis and compared it to normal skin. We performed VDR and RXR immunohistochemistry of 76 controls (normal skin), 49 actinic keratosis, 99 basal cell carcinomas and 96 squamous cell carcinomas from formalin-fixed paraffin-embedded, resulting from surgical procedures. There was a clear pattern in the control group (p<0.001), with the positivity of both receptors, VDR and RXR. Actinic keratosis differed from the basal cell carcinoma and control groups concerning RXR expression (p<0.001). SCC was negative for both receptors, differing in all groups (p<0.001). The site of positivity (nuclear, cytoplasmatic, or both) of VDR differed between all groups (p<0.001). To date, our series is the largest of VDR and RXR immunohistochemistry concerning non-melanoma skin cancer. Our findings reinforce the need to understand the pathways involving VDR and RXR to direct therapies and prevention maneuvers.

Abstract
Jorge Lobo’s disease (JLD) is a chronic, granulomatous fungal infection caused by the traumatic implantation of the fungus Lacazia loboi in the cutaneous and subcutaneous tissues, with the presence of isolated nodular and coalescent keloidal lesions. Malignant degeneration is rare. This case report describes a 64-year-old male patient with JLD for 30-years who showed a change in the aspect of a lesion in the left lower limb. Histopathological examination confirmed the progression to well-differentiated squamous cell carcinoma (SSC). JLD is highly prevalent in tropical and subtropical regions, requiring monitoring concerning the transformation into SSC in long-term lesions.

Abstract
Lobomycosis is a chronic granulomatous infection caused by the yeast Lacazia loboi, typically found in tropical and subtropical geographical areas. Transmission occurs through traumatic inoculation into the skin, especially in exposed areas, of men who work in contact with the soil. Lesions are restricted to the skin and subcutaneous tissue, with a keloid-like appearance in most cases. The occurrence of squamous cell carcinoma on skin lesions with a long evolution is well known; however, there are scarce reports of lobomycosis that developed into squamous cell carcinoma. The authors report a patient from the Brazilian Amazon region, with lobomycosis and carcinomatous degeneration, with an unfavorable outcome, due to late diagnosis.

Abstract
The penile localization of pigmented Bowen's disease has been rarely reported and has been mostly related to human papillomavirus infection. Early diagnosis and treatment are important to prevent progression to invasive squamous cell carcinoma. However, diagnosis can be challenging because it may be difficult to distinguish from melanoma, even using dermoscopy. Reflectance confocal microscopy may be useful in suggesting the bedside diagnosis before the histopathological confirmation. A case of penile pigmented Bowen's disease is described along with its dermoscopy and reflectance confocal microscopy findings and their correlation with histopathology.

Abstract
Carcinoma cuniculatum is a locally aggressive, low-grade variant of squamous cell carcinoma. Though primarily a tumour of the skin, it has also been found to be arising from various mucosal surfaces including oral mucosa. When it occurs in the mandible it starts as a mucosal lesion which progressively invades the jaw and destroys the underlying bone, often presenting as a cystic lesion. With only around 30 cases reported in the mandible, this entity remains an elusive one for the pathologist and all except a few cases reported so far, had been misdiagnosed initially. The delay in the diagnosis is a major concern as it results in further progression of the disease with extensive involvement of bone and associated soft tissue structures. The aim of this article is to discuss the histopathological challenges faced in arriving at the diagnosis of a case of carcinoma cuniculatum involving the mandible. Owing to its overlapping clinico-pathological characteristics with odontogenic keratocyst the lesion has been misdiagnosed initially resulting in inadequate management, leading to multiple recurrences and unexpected complications. As a few cases like the present one had been erroneously diagnosed as odontogenic keratocyst previously, it becomes important to identify the varied clinical presentation and unique histopathological characteristic of carcinoma cuniculatum of mandible to help us in recognizing this often-missed entity at an earlier stage, so that it can be managed effectively.

Abstract
BACKGROUND The vermilion lip is a unique anatomical junction between cutaneous and mucosal surfaces. Squamous cell carcinoma (SCC) of the vermilion lip (vlSCC) was previously classified as oral SCC (oSCC) under the American Joint Committee on Cancer (AJCC) 7th edition (AJCC7), but has been recategorized as a cutaneous SCC of the head and neck (HNcSCC) in the AJCC 8th edition (AJCC8). We investigated the locoregional control (LRC), disease-free survival (DFS), and overall survival (OS) for the various pathological T categories and disease stages of vlSCC as per AJCC8. METHODS We performed a retrospective cohort study of 297 patients diagnosed with vlSCC between January 2004 and February 2019. For this study, vlSCC cases were staged according to both AJCC7 and AJCC8. Kaplan-Meier survival curves and Cox regression models were used to analyze differences in LRC, DFS, and OS between each pT category and disease stage, and log-rank tests were performed for subgroup analysis. RESULTS Restaging of vlSCC using the AJCC8 resulted in 19% of patients being upstaged to pT3, and 16% being upstaged to stage III. No patients were downstaged in pT stage or overall stage. CONCLUSIONS Our study shows that when the AJCC8 HNcSCC staging system is applied to vlSCC, there are important aberrations leading to unwarranted upstaging of pT1 and redundancy of pT2. Understanding of these limitations are important in considering treatment escalation.

Abstract
Objective: To study the significance of induction chemotherapy and subsequent comprehensive therapy for overall survival rate (OS) and larynx dysfunction-free survival rate (LDFS) in patients with advanced hypopharyngeal carcinoma. Methods: Patients who met the inclusion criteria with the diagnoses of advanced hypopharyngeal carcinoma between 2011 and 2017 received 2 or 3 cycles of TPF regimen induction chemotherapy. Patients who attained complete response (CR) received radical chemotherapy. Patients who attained partial response (PR) and the reduction of tumor volume was more than 70% were defined as large PR and received concurrent chemoradiotherapy. When the tumor volume reduction of PR patients was less than 70%, they were defined as small PR. (CR+large PR) group was defined as effective group. Patients who did not reach CR and large PR were defined as uneffective group and underwent radical surgery and received adjuvant radiotherapy as appropriate after the surgery. The end points of the study were OS, progression-free survival (PFS) and LDFS. Chi-square (χ(2)) test was used for correlation analysis. Survival analysis was performed by the Kaplan-Meier method with a Log-rank test. Cox proportional hazards model was used for univariate and multivariate survival analysis. Results: A total of 260 patients were enrolled in the study. The follow-up period ranged from 5 to 83 months, with an average of 24.7 months. The 3-year and 5-year OS rate was 46.0% and 32.6%, respectively. The 3-year and 5-year PFS rate was 41.0% and 26.6%, respectively. The 3-year and 5-year LDFS rate was 37.9% and 24.8%, respectively. Poor outcome of induction chemotherapy, advanced N stage, strong positive Ki-67 immunohistochemistry (all P<0.001) were negative prognostic factors. The advanced clinical stage was positively related to the poor outcome of induction chemotherapy (P=0.015). There was no significant difference in OS and PFS between the large PR group and the small PR group (all P>0.005). Conclusion: TPF regimen induction chemotherapy and subsequent comprehensive therapy for patients with advanced hypopharyngeal carcinoma may improve the quality of life of patients, with high OS rate and LDFS rate.

Abstract
Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma skin cancer, and its incidence is increasing globally. In Korea, there were 12,516 diagnosed cases of cSCC between 1999 and 2014. Surgical treatment, for which several options are available, is the standard of care for cSCC and securing a sufficient surgical resection margin is always important. cSCC of the scalp sometimes exhibits unusually aggressive behavior. In this article, we report a case of cSCC of the scalp with invasion into the skull and dura mater.

Abstract
Objective: To investigate the expression of microRNA-140-5p (miR-140-5p) in esophageal squamous cell carcinoma (ESCC) and its role in cell proliferation and invasion of ESCC. Methods: Real-time quantitative PCR (qPCR) was used to detect the expression levels of miR-140-5p in ESCC tissues and cells. Negative control and miR-140-5p mimic were transfected into Eca109 and KYSE70 cells. CCK-8 kit and Transwell assay were employed to examine the changes of cell proliferation and invasion ability after transfection, respectively. The dual-luciferase reporter assay was used to assess the interaction of miR-140-5p with Glut1. Western blot was utilized to detect the Glut1 protein expression after transfection. Results: Analysis of the related GEO datasets revealed that the expression of miR-140-5p in ESCC tissues was significantly lower than that in normal tissues (P<0.01). The qPCR testing demonstrated that the expression of miR-140-5p in ESCC tissues and cells was markedly lower than that in normal tissues and normal esophageal epithelial cell Het-1A (P<0.01). The miR-140-5p expression was closely associated with tumor differentiation, TNM staging and lymph node metastasis in ESCC patients. The survival rate of ESCC patients with high miR-140-5p level was higher than those with low miR-140-5p level (P<0.05). Besides, addition of miR-140-5p mimic significantly upregulated the expression of miR-140-5p in Eca109 and KYSE70 cells, and suppressed cell proliferation and invasion in Eca109 and KYSE70 cells. The dual-luciferase reporter assay showed that Glut1 was a direct target of miR-140-5p in ESCC cells, and its expression was upregulated in ESCC tissues. Glut1 expression was inversely associated with miR-140-5p expression in ESCC tissues. MiR-140-5p mimic dramatically inhibited the expression of Glut1 in Eca109 and KYSE70 cells. Conclusions: MiR-140-5p plays an essential role in ESCC development and progression. Targeting at miR-140-5p/Glut1 may be a novel therapeutic strategy for ESCC patients.

Abstract
A 58-year-old male patient with diabetic foot ulcer was admitted to the Second Affiliated Hospital of Zhejiang University School of Medicine on December 11, 2018. The patient was treated with local debridement, vacuum sealing drainage treatment, and dressing change and discharged after basic wound healing. On January 15, 2019, the patient was hospitalized again due to local infection and rupture of wound surface. He underwent a surgical debridement on the third day after second admission and was given intravenous infusion of 0.4 g teicoplanin twice daily. Histopathological examination after surgery showed keratinizing squamous-cell carcinoma. An extended squamous-cell carcinoma resection plus autologous split-thickness skin grafting and vacuum sealing drainage treatment was carried out on the 10th day after second admission. The patient's whole body turned red after surgery with rash, recurrent fever over 39 ℃, leucopenia, and thrombocytopenia. A multi-disciplinary consultation of physicians attributed these symptoms to teicoplanin-induced hypersensitivity syndrome. After withdrawal of teicoplanin and administration of hormone, the patient's temperature returned to normal, and the leucocyte count and platelet count recovered gradually. The patient was cured and discharged on the 49th day after second admission. The case presented reminds us of need to strictly follow the indications of teicoplanin prior to medication, be resolute to the administration and withdrawal, and be alert to adverse drug reactions when above-mentioned abnormalities occur, meanwhile, infection and rheumatic diseases are excluded.

Abstract
BACKGROUND The diagnostic accuracies of the imaging studies should be clearly acknowledged in managing head and neck cancer patients; however, the accuracies of preoperative imaging studies in detecting retropharyngeal lymph node (RPLN) metastasis are still not clarified. This study was to evaluate diagnostic accuracies of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography-computed tomography (PET-CT) in detecting RPLN metastasis of head and neck squamous cell carcinomas. METHODS For 123 patients who had performed RPLN dissection during the surgery of their squamous cell carcinoma of the head and neck, preoperative CT, MRI, and/or PET-CT were reviewed for RPLN metastasis in a blinded fashion by one experienced radiologist. Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of each imaging modality were assessed, by comparing with the histopathologic findings of the resected RPLNs that served as the standard of reference. RESULTS RPLNs were pathologically positive for metastasis in 43 of the 123 patients (35%). Sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy in detecting metastasis to RPLN were 65, 94, 85, 83, and 84% for CT; 74, 94, 87, 87 and 87% for MRI; 83, 93, 89, 89 and 89% for PET-CT, respectively. When all the three imaging modalities were considered together (n = 74), they offered sensitivity of 90%, specificity of 91%, positive predictive value of 87%, negative predictive value of 93%, and accuracy of 91%. CONCLUSIONS The preoperative imaging studies offered relatively high specificity rates, but rather low sensitivity rates. The three imaging modalities altogether increased diagnostic accuracies, which highlights the potential of the three studies when used altogether can minimize missed diagnoses of RPLN metastasis.

Abstract
The objective of the present study was to evaluate the role of microRNA-mediated remodeling of the extracellular matrix in the process of tumor invasion of oral squamous cell carcinoma and to evaluate its relationship with the prognosis of these patients. This was a retrospective study on material from the paraffin blocks of patients operated on for oral squamous cell carcinoma, in addition to a group of healthy oral mucosa samples of paired patients. miR-1-3p, miR-133-3p, and miR-21-5p were differentially expressed between the superficial and deep tumor groups. miR-21-5p was the one with the greatest accuracy in the differentiation between superficial and deep tumors. By immunohistochemistry, the group of deep tumors showed greater immunoreactivity to matrix metalloproteinases 2 and 9 and laminin α in tumor-associated fibroblasts, with consequent degradation of the basal membrane, measured by greater loss of continuity of type IV collagen. This process was also associated with lower and higher expression of miR-1-3p and miR-21-5p, respectively. There was also a trend toward better overall and disease-free survival rates in patients with higher miR-133a-3p. The present study showed the interaction between microRNAs and extracellular matrix remodeling in oral squamous cell carcinoma.

Abstract
Oral and oropharyngeal squamous cell carcinomas are the most common malignant tumours of the oral and maxillofacial region. A standardized pathological diagnosis report for oral and oropharyngeal squamous cell carcinoma should provide not only the pathological diagnosis itself as much accurate as possible, but also the information related to assessment of prognosis and strategy of treatment for the patient. An expert group organized by Society of Oral Pathology, Chinese Stomatological Association has set a guideline for the tissue fixation, gross examination and format of the pathological diagnosis report of oral and oropharyngeal squamous cell carcinoma. The guideline covers the important changes in clinical and pathological aspects of oral and oropharyngeal squamous cell carcinomas in recent years, such as depth of invasion in T category, extranodal extension in N category and human papilloma virus-associated squamous cell carcinoma in oropharyngeal carcinomas. Hopefully the guideline will improve the quality of pathological reports of oral and oropharyngeal squamous cell carcinomas and provide reliable data on clinical therapy and prognosis evaluation of patients with oral and oropharyngeal squamous cell carcinomas in China.

Abstract
The most common forms of nonmelanocytic skin cancer (NMSC) are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The growing incidence of skin cancer in the Republic of Korea has sparked increasing scientific interest in these types of tumors. In the case described herein, multiple NMSCs occurred asynchronously in various areas of the body in a single patient. A 67-year-old man presented with an ulcerative lesion on the right retro-auricle and multiple keratinized masses on the back and face. The right retro-auricular lesion was diagnosed as BCC, and the keratinized masses on the patient’s back and face were diagnosed as SCC. He subsequently presented with numerous pigmented skin lesions on the forehead, temple, pre-auricle, neck, right forearm, right hand, and both thighs. One lesion on the neck was diagnosed as BCC, and five lesions on the right hand and forearm were diagnosed as SCC. The patient was also diagnosed with supraglottic SCC and external auditory canal SCC. An otolaryngologist performed radical excision of the primary SCC. Suspected skin cancer lesions observed on the face and both ears were diagnosed as SCC. Patients with multiple NMSCs are at an elevated risk for additional skin cancers, making periodic follow-up important; furthermore, all suspicious lesions should be biopsied.

Abstract
Objective: To evaluate the clinical effects of anterolateral thigh free flap with fascia lata in the repair of dura mater defect after resection of head squamous cell carcinoma. Methods: From June 2016 to June 2018, Xijing Hospital of Air Force Medical University applied the free transplantation of anterolateral thigh flap with fascia lata to repair the dura mater defect of 12 patients with head squamous cell carcinoma, including 9 males and 3 females, aged from 35 to 74 years. The size of scalp soft tissue defects in patients after carcinoma resection ranged from 12 cm×10 cm to 24 cm×21 cm, and the size of dura mater defect of patients ranged from 7 cm×6 cm to 16 cm×14 cm. The size of flap of patients ranged from 14 cm×12 cm to 27 cm×24 cm, and the size of fascia lata ranged from 8 cm×7 cm to 17 cm×15 cm. The superficial temporal artery and middle temporal vein were connected by end to end anastomosis with the first musculocutaneous perforating branch of the descending branch of lateral femoral artery and its accompanying vein. The flap donor area was transplanted with autologous split-thickness skin graft from trunk and fixed with packing. Postoperative survival of flaps and skin grafts was observed. The patients were followed up regularly. The cranial magnetic resonance imaging was performed to observe the recurrence of intracranial tumors and dural integrity, shape of the flap and whether the donor site region was left with significant dysfunction were observed. Results: All the flaps and skin grafts survived well in 12 patients after surgery. Ten patients had primary healing at the edge of the flap suture; 2 patients had local sinus tract formation at the suture site of flap, with a small amount of cerebrospinal fluid leakage, and were recovered after outpatient dressing change. The patients were followed up for 10 to 36 months, and 3 patients with tumors involving in the dura mater sagittal sinus region had postoperative intracranial tumor recurrence. The tumor was resected again. All the patients had good dural integrity. The flaps of all patients were in good shape, and no obvious dysfunction remained in the flap donor site. Conclusions: Free transplantation of anterolateral thigh flap with fascia lata is an effective and reliable method to repair the dura mater defect following head squamous cell carcinoma resection. It can repair the scalp and dura mater defects caused by the invasion of squamous cell carcinoma and provide possibilities for skull reconstruction.

Abstract
Objective: To analyze the pathological classification and age distribution of primary neoplasms of the lacrimal drainage system. Methods: Retrospective case series study. A total of 64 patients (65 eyes) were diagnosed with primary neoplasms of the lacrimal drainage system and received surgery at Tianjin Eye Hospital from January 2006 to December 2016. All the clinical data of the patients were analyzed, including gender, diseased eye, age, clinical manifestations, composition of benign and malignant masses, and prognosis. The histopathological composition and age distribution of patients with primary lacrimal mass, lacrimal duct mass and lacrimal sac mass were analyzed according to the different diseased sites. Results: Twenty-three patients (24 eyes) were male, and 41 patients (41 eyes) were female. The right eye was involved in 36 patients, the left eye in 27 patients, and both eyes in one patient. The age at diagnosis ranged from 12 to 78 years old [mean, (46±4) years]. The course of disease was (13.1±4.2) months, ranging from 1 month to 7 years. The chief complaint was tear discharge in 43 patients, tumor in 19 patients, and abscess discharge in 2 patients. There were 29 patients with angular displacement and 21 patients with swelling pain. There were 51 patients with benign lesions, 4 with borderline lesions, and 9 with malignantlesions. These neoplasms consisted of primary peripunctal neoplasms in 17 patients, primary canalicular neoplasms in 2 patients, and primary lacrimal sac neoplasms in 45 patients. All primary peripunctal neoplasms (17 cases) were benign, among which nevi (10 cases) occupied the first place. All primary canalicular neoplasms (2 cases) were benign, there were 1 case of epidermoid cysts and 1 case of degenerative disease. Among the primary benign lacrimal sac masses (32 cases), mucous epithelial cysts (9 cases), dermoid cysts (6 cases), and epidermoid cysts (6 cases) occupied the first three places. Among the primary borderlin lacrimal sac masses (4 cases), there were 2 cases of giant cell tumor of soft tissue, 1 case of solitary fibrous tumor, and 1 case of inflammatory myofibroblastic tumor. The primary malignant mass of lacrimal sac (9 cases) was dominated by squamous cell carcinoma (3 cases). In terms of age distribution, the patients with primary peripunctal mass were mainly in the group of 40-59 years old (14 cases). The primary benign mass of lacrimal sac mainly occurred in the group of less than 40 years old (15 cases) and the group of 40-59 years old (11 cases). The patients with primary lacrimal sac borderline and malignant masses were all in the groups of over 40 years old. A total of 49 patients were followed up for 27 months to 16 years. The average follow-up time was (57.2±3.8) months. Lacrimal sac transitional cell carcinoma relapsed 7 months after surgery in one patient, and lacrimal sac melanoma relapsed 1 year after surgery in one patient. The patients did not relapse in 24 months and 38 months after surgery respectively. There were no recurrence of other cases. Conclusions: Primary peripunctal neoplasms are mostly characterized with benign lesions, among which nevi are most common. Mucous epithelial cysts, epidermoid cysts, and dermoid cysts are the major benign lacrimal sac neoplasms. Squamous cell carcinomas are the most common malignant lacrimal sac neoplasms. The malignant tumor of lacrimal sac often occurs in the middle-aged and elderly patients. (Chin J Ophthalmol, 2020, 56: 364-369).

Abstract
Skin cancer, which often occurs as a result of skin exposure to ultraviolet light radiation, usually presents with characteristic abnormal features, such as ulcerative lesions, irregular morphology, bleeding, and excessive growth. Therefore, skin cancer rarely resembles a benign tumor on visual inspection. Nonetheless, squamous cell carcinoma and basal cell carcinoma with nodular or polypoid features can have a similar appearance to that of benign tumors, meaning that they are sometimes misdiagnosed as benign. As benign and malignant tumors have some overlapping features, clinicians sometimes use additional imaging techniques such as ultrasonography to improve the accuracy of the diagnosis because even a malignant tumor that externally resembles a benign tumor generally has internal morphological features characteristic of malignancy, such as invasion and irregular borders. However, these imaging tools also have limitations, and punch or excisional biopsy can be needed if malignancy cannot be completely ruled out. Herein, we report a case of skin malignancy initially misdiagnosed as a benign epidermal cyst based on external visual inspection and ultrasonography.

Abstract
Non-melanoma skin cancer is the most prevalent malignancy in fair-skinned people and its incidence is increasing. Recently, studies have suggested that antihypertensive drugs may increase the risk of these tumors, particularly hydrochlorothiazide, due to its photosensitizing properties. The Portuguese National Authority for Medicines and Health Products, INFARMED, has issued an alert to healthcare professionals concerning the increased risk of non-melanoma skin cancer in patients exposed to cumulative doses of this drug. However, study results have been heterogeneous and sometimes conflicting. The high incidence of non-melanoma skin cancer and the large number of patients under chronic hydrochlorothiazide therapy may thus have important public health consequences. In this article, the authors review the published evidence and conclude that there may be an association between hydrochlorothiazide use and the risk of non-melanoma skin cancer, but also point out some limitations of the studies in the literature. It is important to promote preventive strategies against sun exposure, regular skin examinations, and individual assessment of the benefits of hydrochlorothiazide use, particularly in patients with previous skin cancer.

Abstract
Background The incidence of skin cancer, which is primarily caused by exposure to ultraviolet radiation, has steadily increased in recent years. The authors of the present study sought to investigate changes in the epidemiology of skin cancer by conducting a retrospective review of patients diagnosed with skin cancer who received related care at a single medical institution. Methods The present study included patients who were diagnosed with skin cancer and received treatment at Gyeongsang National University Hospital from 2008 to 2018. The site and type of skin cancer, the number of patients with skin cancer each year, the sex and sex ratio of the patients, and changes in patients’ age at first diagnosis were examined through retrospective chart reviews. Results The number of patients with skin cancer significantly increased, but statistically significant changes were not found in patients’ sex, skin cancer sites, or the types of skin cancer. However, patients’ age at the first diagnosis of skin cancer showed a statistically significant decrease starting in 2015. Conclusion In this study, the number of patients with skin cancer increased over time. However, patients’ age at first diagnosis has decreased since 2015. Therefore, younger patients should take care to prevent skin cancer, and further research on the causes of skin cancer in younger patients is needed.

Abstract
Objective: To investigate the effects of c-Met inhibitor AMG-102 on the proliferation and apoptosis of laryngeal squamous carcinoma Hep-2 cells and the underlying mechanism. Methods: Laryngeal squamous carcinoma cell line Hep-2 cells were treated with 2.5, 5 and 10 μmol/L AMG-102, respectively. The proliferation activities of Hep-2 cells were detected by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2H-tetrazolium bromide (MTT). The apoptotic rate of Hep-2 cells was detected by flow cytometry analysis and Hoechst staining. The mRNA expression levels of apoptosis-related genes were detected by real-time quantitative polymerase Chain reaction (RT-qPCR), and the protein expressions of c-Met/PI3K/AKT pathway were detected by western blot. Results: Compared with the control group, the proliferation rates of Hep-2 cells treated with 2.5, 5 and 10 μmol/L AMG-102 for 24 hours were (89.8±1.1)%, (79.8±1.0)% and (69.1±1.2)%, respectively; for 48 hours were (76.8±2.0)%, (60.2±1.1)% and (49.8±1.2)%, respectively; for 72 hours were (50.1±2.0)%, (41.5±1.1)% and (33.6±1.0), respectively, with significant differences (all P<0.05). The apoptotic rates of Hep-2 cells treated with 2.5, 5 and 10 μmol/L AMG-102 for 48 hours were (16.09±1.53)%, (27.51±2.02)% and (36.57±1.42)%, respectively, which were significantly higher than (3.62±0.10) % in the control group (all P<0.05). After treated with 2.5, 5 and 10 μmol/L AMG-102 for 48 hours, the relative expression levels of Bcl-2 mRNA in Hep-2 cells were 0.58±0.13, 0.38±0.12 and 0.20±0.13, respectively; the relative protein expression of p-Met were 80.0±3.8, 50.6±4.2 and 28.5±1.3, respectively; the relative protein expression of p-PI3K were 87.1±0.9, 54.2±1.2 and 21.0±1.2, respectively; the relative protein expression of p-AKT were 98.7±5.6, 56.9±3.2 and 32.2±4.3, respectively; which were significantly lower than those in the control group (all P<0.05). The relative expression levels of Bax mRNA were 1.78±0.13, 2.37±0.14 and 3.05±0.13, respectively, and the relative expression levels of caspase-3 mRNA were 1.98±0.14, 2.47±0.14 and 3.15±0.13, respectively, which were significantly higher than those in the control group (all P<0.05). Conclusion: c-Met inhibitor AMG-102 could inhibit the proliferation and induce apoptosis of laryngeal squamous carcinoma Hep-2 cells by regulating the c-Met/PI3K/Akt pathway.

Abstract
Objective: To analyze the differentially expressed genes related to the chemosensitivity with the TPF regimen for hypopharyngeal squamous cell carcinoma and to measure potential functional targeting genes expressions. Methods: Twenty-nine patients with primary hypopharyngeal cancer who underwent induction chemotherapy with TPF from January 2013 to December 2017 in Beijing Tongren Hospital were enrolled for microarray analysis, including 28 males and 1 female, aged from 43 to 73 years old. Among them, 16 patients were sensitive to chemotherapy while 13 patients were non-sensitive. Illumina Human HT-12 Bead Chip was applied to analyze the gene expressions and online bioinformatics analysis was used to analyze the differentially expressed genes. Reverse transcription and quantitative real-time PCR (RT-qPCR) was used to measure the mRNA expression of potential functional genes of TPF induction chemotherapy in 43 samples, 29 from original patients and 14 from additional patients. Graphpad prism 7.0 software was used for statistical analysis. Results: A total of 1 381 significantly differentially expressed genes were screened out. By GO analysis, up-regulated genes included sequestering in extracellular matrix, chemokine receptor binding and potassium channel regulator activity; down-regulated genes included regulation of angiogenesis, calcium ion binding and natural killer cell activation involved in immune response. With KEGG database analysis, down-regulated pathways included ECM-receptor interaction and peroxisome and up-regulated pathways included Glutathione metabolism and PPAR signaling pathway. The expressions of CD44 and IL-6R were significantly different and appeared biologically significant. CD44 was significantly upregulated in insensitive tissues (0.54±0.06) compared with sensitive tissues (0.33±0.04)(P<0.01). IL-6R was significantly downregulated in insensitive tissues (0.44±0.03) compared with sensitive tissues. (0.68±0.03) (P<0.01). Conclusion: CD44 and IL-6R may be potentially functional genes of TPF induction chemotherapy in hypopharyngeal squamous cell carcinoma.

Abstract
On 18th October 2018, a 49 years old man with right thigh proximal medial swelling and pain was received in the Department of Pathology, People's Hospital of Deyang of Sichuan Province. The patient had experienced amputation twice because of burn in right lower limb 46 years ago. Cicatricial squamous cell carcinoma metastasis in right thigh proximal medial was diagnosed by fine needle aspiration cytology in our hospital. The wound remained ulcered and unhealed after biopsy in a higher level hospital. The patient died in ten days after first chemotherapy which was required by the patient. This case suggests that clinician should perform pathological examination on burn patients with scar ulcer as soon as possible to avoid delay in treatment, which may cause carcinogenesis deterioration and metastasis.

Abstract
Erythroderma as the first manifestation of a solid organ malignancy is rare. The underlying cancer is a challenging condition to diagnose. There are a few cases of erythroderma in cancer patients reported in the literature. We here describe the case of a 70-year-old man who presented with asthenia, weight loss, dry cough and total body erythema with desquamation over the past month. A chest computed tomography scan showed a nodular lesion, which was finally diagnosed as a squamous cell lung carcinoma. To our knowledge, as an erythroderma presentation, only 13 cases have been reported in the literature. This case report demonstrates the need to search for a neoplasm in patients presenting with erythroderma, particularly in the presence of accompanying debilitating symptoms.

Abstract
Conjunctival malignancies are rare. However, some of these tumors are among the most aggressive malignancies in ophthalmology and require radical forms of therapy that may lead to blindness or loss of the ipsilateral eye and tumor-associated death. The most relevant primary conjunctival malignancies for oncologists are squamous cell carcinoma, malignant melanoma and malignant lymphoma. Surgical therapy is the primary treatment for squamous cell carcinoma and malignant melanoma. An adjuvant therapy in the form of topical chemotherapy or radiation is necessary in most cases. The isolated malignant lymphoma of the conjunctiva is biopsied excisionally if possible. However, if an incisional biopsy was unavoidable, additional irradiation should be performed; malignant lymphoma generally responds very well to relatively low irradiation doses with a good prognosis quad vitam. More aggressive forms, such as diffuse large cell B‑cell lymphoma or mantle cell lymphoma, must also be treated systemically at an early stage.

Abstract
Objective: To analyze the 13 years trend in proportion, risks factors and clinicopathological characteristics of young women with stage Ⅰa2 to Ⅱa2 cervical cancer by using multi-center data of cervical cancer in China. Methods: The clinicopathological data of 46 313 patients with cervical cancer treated from 37 hospitals in China were obtained from January 2004 to December 2016. Using clinical and pathologic data, each patient's stage was reclassified by the 2018 International Federation of Gynecology and Obstetrics (FIGO) staging system. A total of 19 041 patients were selected according to the following criteria: FIGO stage Ⅰa2 to Ⅱa2, underwent type B or C radical hysterectomy and pelvic lymphadenectomy. All the patients were divided into two groups: the study group of 1 888 patients aged 35 years or younger and the control group of 17 153 patients aged over 35 years. The 13 years trend in proportion of young women with stage Ⅰa2 to Ⅱa2 cervical cancer, risks factors and clinicopathological characteristics of two groups were retrospectively analyzed. Results: (1) The total number of hospitalized patients with stage Ⅰa2 to Ⅱa2 cervical cancer increased annually. However, a downward trend of patients aged 35 years or younger was observed (P<0.01) . The constituent ratio of patients aged 35 years or younger was significantly greater during 2004-2010 than that during 2011-2016 [12.6% (820/6 484) and 8.5% (1 068/12 557) , respectively; χ(2)=82.101, P<0.01]. (2) Compared with patients aged over 35 years, patients aged 35 years or younger had an earlier age at menarche, a later age at marriage, lesser gravida and parity (all P<0.01). The positive rate of high-risk HPV infection was not statistically different between two groups (all P>0.05). (3) The proportions of stage Ⅰ, exophytic type and non-squamous histological type in patients aged 35 years or younger were clearly higher than those in patients aged over 35 years (83.4% vs 68.5%, P<0.01; 63.2% vs 56.2%, P<0.01; 13.9% vs 12.0%, P<0.05, respectively). Whereas the poor differentiation ratios of the two groups had no statistical significance (P>0.05). (4) As for the postoperative pathological risk factors, the rate of surgical margin involvement in patients aged 35 years or younger was lower than that aged over 35 years (1.1% vs 1.8%, P<0.05), and the rate of depth of stromal invasion >1/2 in patients aged 35 years or younger was lower than that in patients aged over 35 years (40.1% vs 50.9%, P<0.01). In addition, there were no significant difference in parametrial margin involvement, tumor size and lymph vascular space invasion between two groups (all P>0.05). Conclusions: The trend in proportion among hospitalized patients for stage Ⅰa2 to Ⅱa2 cervical cancer in young women is decreasing yearly. Compared with cervical cancer in middle-aged and elderly women, cervical cancer in young women have an earlier age at menarche, a higher proportion of stage Ⅰ patients and non-squamous histological type. In terms of the postoperative pathological risk factors, the rate of surgical margin involvement and depth of stromal invasion >1/2 in young women with cervical cancer are lower than in middle-aged and elderly women.

Abstract
Objective: To explore the effects and postoperative prognostic factors in cervical cancer patients received neoadjuvant chemotherapy combined with surgery and post-operative adjuvant therapy. Methods: A total of 177 patients with cervical cancer at International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ b2, Ⅱ a2 who underwent neoadjuvant chemotherapy (NACT) followed by surgery with and without adjuvant therapy in Cancer Hospital, Chinese Academy of Medical Sciences were included. Univariate and multivariate analyses of 5-year overall survival (OS) rate and 5-year disease-free survival (DFS) rate were performed. Results: Of 177 patients, 133 (75.1%) had stage Ⅰb2 and 44 (24.9%) had Ⅱa2 cancers. After NACT, overall response rate was 63.3% (112/177) including 12 cases of complete response (CR), 100 of partial response (PR) and no progressive disease (PD) case. At a median follow-up of 59.2 months, the 5-year DFS rate was 73.6% and the 5-year OS rate was 86.8%. Univariate analysis revealed that lymph node metastasis, deep stromal invasion and tumor size after NACT significantly affected 5-year DFS rate (P<0.05). Lymph node metastasis, deep stromal invasion and tumor size after NACT significantly affected 5-year OS rate (P<0.05). The multivariate analysis showed that, stromal invasion (outer 1/3 or outer 1/2) was independent risk factor of 5-year DFS rate (P<0.05), and 5-year OS rate was significantly affected by tumor size >3 cm after NACT (P<0.05). Conclusions: The effect of NACT in Ⅰ b2, Ⅱ a2 squamous carcinoma of the uterined cervix is confirmed. The independent risk factor for 5-year DFS rate in patients received NACT and hysterectomy is deep stromal invasion of the cervix. The presence of tumor size >3 cm after NACT adversely affect 5-year OS rate.

Abstract
Depth of invasion is a newly added index for TNM staging of oral cancer in the eighth edition. Preoperative evaluation of depth of invasion not only provides a reference for surgical margin, but also serves as an independent prognostic factor for predicting lymph node metastases. At present, the main methods for assessing the depth of invasion of tongue squamous cell carcinoma include ultrasound examination, MRI, CT, positron emission tomography (PET) and histopathological examination. This paper summarizes the evaluation method and clinical effect of depth of invasion of tongue cancer, and analyzes its advantages and boundedness. In addition, this study is expected to provide a reference for the surgical treatment of tongue squamous cell carcinoma.

Abstract
Objective: To evaluate preoperative nutritional status and inflammatory status by Nutritional Risk Screening-2002 (NRS-2002) and hematologic inflammatory markers in patients with thoracic esophageal squamous cell carcinoma (ESCC), and to explore their effects on long-term survival prognosis. Methods: A total of 113 patients with thoracic ESCC treated by radical resection were grouped for further analysis according to preoperative NRS-2002 score, systemic inflammation score (SIS) and the combination of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio (CNP) score. The progression free survival (PFS) and overall survival (OS) between groups were compared. Multivariate Cox regression analysis was used to determine the independent prognostic factors of patients with thoracic esophageal squamous cell carcinoma, and the interaction analysis of statistically significant factors was carried out. Results: The median PFS was 21 months for all the patients. The 1-year, 3-year and 5-year PFS rates were 69.0%, 25.7% and 23.1%, respectively. Correspondingly, the median OS was 36 months, and the 1-year, 3-year and 5-year OS rates were 95.6%, 46.2% and 29.2%, respectively. Cox univariate analysis showed that T stage, N stage, TNM stage, SIS, CNP score and NRS-2002 score were significantly associated with PFS and OS (all P<0.05), and sex was associated with PFS (P=0.032) in patients with thoracic ESCC. Furthermore, cox multivariate analysis showed that TNM stage (HR=1.570, P=0.039), NRS-2002 score (HR=2.706, P<0.001) and CNP score (HR=1.463, P=0.011) were independent prognosis factors of PFS in patients with thoracic ESCC. In cox model interaction analysis, there was a positive interaction between NRS-2002 score and CNP score (RR=2.789, P<0.001). Conclusion: Preoperative NRS-2002 score combined with CNP score are risk factors for prognosis of patients with thoracic ESCC, which can be used as prognostic indicators.

Abstract
Objective: To investigate the proportion and role of CD45+ erythroid progenitor cells (EPC) in patients with tongue cancer metastasis. Methods: The initial treatment of tongue cancer patients (n=40) from January 2017 to June 2018 in He'nan Provincial People's Hospital was included in this study. According to the presence or absence of lymph node metastasis, they were divided into tumor group (no lymph node metastasis was found in imaging and pathology) and metastasis group (both imaging and pathology confirmed lymph node metastasis). The expression of Ki-67 was detected by immunohistochemistry and the proportion of CD45+CD71+TER119+EPC was detected by flow cytometry. EPC was sorted by flow cytometry, interleukin-10 (IL-10) and transforming growth factor-β (TGF-β) were detected by enzyme-linked immunosorbent assay (ELISA), and reactive oxygen species (ROS) was detected by flow cytometry. Transwell was used for tumor invasion test; methyl thiazolyltetrazolium (MTT) assay was used to detect proliferation level. Results: There were 20 cases in the tumor group and metastasis group. There was no significant difference between the two groups in terms of age, sex, time of onset and size of tumors. Flow cytometry showed that the ratio of CD45+EPC in peripheral blood of tumor group and metastasis group was (1.2±0.2)% and (3.1±0.2)% (t=7.823, P<0.001). Correlation analysis showed that the ratio of CD45+EPC was positively correlated with the proliferation index of Ki-67 cells (r=0.592, P=0.006). The results of flow cytometry showed that the mean fluorescence intensity (MFI) of ROS in EPC was 102.1±22.9 in tumor group and 530.0±67.2 in metastasis group (t=6.025,P<0.001). The results of ELISA showed that the mass concentrations of IL-10 and TGF-β in EPC supernatant of tumor group were (10.8±1.6) and (3.2±0.8) μg/L, respectively. The mass concentrations of IL-10 and TGF-beta in EPC supernatant of metastasis group were (26.9±3.7) and (6.4±0.9) μg/L, respectively (t=3.956, P=0.003; t=2.595, P=0.027). Transwell results showed that the proportion of invasive cells in the CD45+EPC group [(40.3±4.4)%] was higher than that in the control group [(17.5±2.2)%] (t=4.607, P=0.001). MTT proliferation experiment showed that the proliferation rate of the CD45+EPC group [(52.0±3.3)%] was higher than that of the control group [(30.5±1.9)%] (t=5.656, P<0.001). Conclusions: The proportion of CD45+EPC in patients with tongue cancer metastasis is significantly increased. CD45+EPC can promote the proliferation and metastasis of tongue cancer by secreting immunosuppressive molecules and ROS.

Abstract
Objective: To investigate the expressions of vascular endothelial growth factor (VEGF), hypoxia inducible factor-1 alpha (HIF-1α), and epidermal growth factor receptor (EGFR) in different morphological regions of Marjolin ulcer and their clinical relationship with angiogenesis. Methods: From January 2012 to December 2017, the patients admitted to our hospital who met the inclusion criteria were selected, including 92 patients with Marjolin ulcer [56 males and 36 females, aged (55±15) years], 100 patients with chronic non-cancerous skin ulcer [59 males and 41 females, aged (51±16) years], and 100 patients performed with other skin-related surgery [58 males and 42 females, aged (52±15) years], and they were enrolled into Marjolin ulcer group (MU), chronic non-cancerous ulcer group (CNU), and other skin surgery group (OSS) respectively. The etiology, pathogenic site, ulcer diameter, and course of patients in group MU were retrospectively analyzed. Ulcer tissue specimens from patients of group MU and group CNU and specimens of normal skin tissue attached to the tissue resected during operation from patients of group OSS were collected. The expressions of VEGF, HIF-1α, EGFR, and CD34 in the above-mentioned tissue and the surrounding normal skin, ulcer, epitheliomatous hyperplasia, and canceration areas in Marjolin ulcer tissue were detected by immunohistochemical method, and the positive expression rate and protein expression level were calculated. Data were processed with Pearson chi-square test, Mann-Whitney U test, Bonferroni method, and Bonferroni correction, and Spearman correlation analysis was used to analyze the relationship among the total protein expression levels. Results: In group MU, burns accounted for 91.3% (84/92) of the causes of patients, 44.6% (41/92) of the patients had tumors in the lower extremities, 62.0% (57/92) of the patients had skin ulcer diameter of 2.1-5.0 cm, and 75.0% (69/92) of the patients had a course of disease of more than 20 years. The positive rates of VEGF, HIF-1α, and EGFR in ulcer tissue of patients in group CNU were 41.0% (41/100), 77.0% (77/100), and 83.0% (83/100), respectively, significantly higher than those of normal skin tissue of patients in group OSS [12.0% (12/100), 45.0% (45/100), and 67.0% (67/100), χ(2)=21.589, 21.522, 6.827, P<0.01]. The positive rates of VEGF, HIF-1α, and EGFR in ulcer tissue of patients in group MU were 91.3% (84/92), 100.0% (92/92), and 100.0% (92/92), respectively, which were significantly higher than those in corresponding tissue of patients in group CNU and group OSS (χ(2)=53.372, 24.772, 17.159; 120.543, 72.777, 36.661, P<0.01). In ulcer tissue of patients in group MU, the positive expression rates of VEGF in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than the rate in surrounding normal skin area (χ(2)=87.120, 42.368, 89.624, P<0.01); the positive expression rates of VEGF in canceration and ulcer areas were significantly higher than the rate in epitheliomatous hyperplasia area (χ(2)=22.586, 16.060, P<0.01). In ulcer tissue of patients in group MU, the positive expression rates of EGFR in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than the rate in surrounding normal skin area (χ(2)=21.679, 27.600, 27.600, P<0.01), but the positive expression rates of HIF-1α in four morphological areas were similar (χ(2)=3.008, P>0.05). In ulcer tissue of patients in group MU, the protein expression levels of VEGF and CD34 in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than those in surrounding normal skin area (Z=-6.765, -6.819; -6.765, -6.640; -6.765, -6.819, P<0.01), the protein expression levels of VEGF and CD34 in epitheliomatous hyperplasia area were significantly lower than those in ulcer area (Z=-4.484, -5.266, P<0.01), and the protein expression levels of VEGF and CD34 in canceration area were significantly higher than those in ulcer area (Z=-6.427, -6.723, P<0.01) and epitheliomatous hyperplasia area (Z=-6.427, -6.462, P<0.01). In ulcer tissue of patients in group MU, the protein expression levels of HIF-1α and EGFR in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than those in surrounding normal skin area (Z=-6.819, -6.393; -6.819, -6.393; -6.819, -6.393, P<0.01), the protein expression levels of HIF-1α and EGFR in ulcer area were significantly lower than those in epitheliomatous hyperplasia and canceration areas (Z=-6.118, -5.638; -6.640, -6.393, P<0.01), and the protein expression levels of HIF-1α and EGFR in canceration area were significantly higher than those in epitheliomatous hyperplasia area (Z=-6.558, -6.819, P<0.01). In ulcer tissue of patients in group MU, the total protein expression levels of VEGF, HIF-1α, and EGFR were significantly positively correlated with the total protein expression level of CD34 (r=0.772, 0.415, 0.502, P<0.01) respectively; the total protein expression level of EGFR was significantly positively correlated with that of HIF-1α (r=0.839, P<0.01), both of which were significantly positively correlated with the total protein expression level of VEGF (r=0.531, 0.440, P<0.01) respectively. Conclusions: The expressions of VEGF, HIF-1α, and EGFR are the highest in Marjolin ulcer canceration area, and EGFR may promote angiogenesis through HIF-1α or directly increasing the expression of VEGF.

Abstract
Objective: Using propensity score matching method (PSM) to investigate the clinical effect of postoperative adjuvant radiotherapy and postoperative concurrent chemoradiotherapy for locally advanced hypopharyngeal squamous cell carcinoma. Methods: From July 2007 to July 2018,174 postoperative patients with locally advanced hypopharyngeal squamous cell carcinoma were enrolled in pre-PSM cohort, including 168 males and 6 females, the median age was 60 years old (ranged from 37 to 79 years old).Loco-regional control (LRC),progression-free survival (PFS) and overall survival (OS) were compared and analyzed between the patients treated with postoperative adjuvant radiotherapy and postoperative concurrent chemoradiotherapy (cisplatin was given in a dose of 80 mg/m(2) on days 1, 22, and 43). After the propensity score matching (PSM), 61 sub-pairs of 122 patients were generated in post-PSM cohort. Survival rate were assessed with Kaplan-Meier method and Log-rank test. Results: After the propensity score matching(PSM), 61 sub-pairs of 122 patients were generated in post-PSM cohort.The patients were followed up for 3-135 months, the median follow-up was 42 months. No significant differences in 3-year and 5-year LRC, PFS, OS were observed between the two groups (P>0.05) . For postoperative patients who had high-risk factors (extracapsular extension of nodal disease, and/or vascular embolism, and/or lymph node metastasis≥2, and/or positive surgical margin, and/or perineural infiltration),there were significant differences between the two groups in 3-year PFS (60.99% vs 84.49%,P<0.05), 5-year PFS (35.47% vs 56.97%,P<0.05) and 5-year LRC (41.02% vs 68.50%, P<0.05), but no significant difference was found in OS between the two groups (P>0.05). Conclusion: Postoperative concurrent chemoradiotherapy was more efficacious than postoperative radiotherapy alone in terms of loco-regional control and PFS for high-risk postoperative patients with locally advanced hypopharyngeal squamous cell carcinoma.

Abstract
BACKGROUND/AIMS We investigated the efficacy and toxicity of a weekly schedule of docetaxel and cisplatin as a first-line treatment in patients with recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC). METHODS In this study, 18 patients with previously diagnosed R/M HNSCC were treated with combination chemotherapy of weekly docetaxel 35 mg/m2 (day 1 and 8) and cisplatin 70 mg/m2 (day 1) as first-line chemotherapy, repeated every 3 weeks. RESULTS Partial response and stable disease were observed in six patients (33.3%; 95% confidence interval [CI], 11.1% to 55.6%) and six patients (33.3%; 95% CI, 11.1% to 55.6%), respectively. The median overall survival and progression-free survival were 11.26 months (95% CI, 8.87 to 15.83) and 5.68 months (95% CI, 4.80 to 6.51), respectively. The major toxicity was grade 1/2 anemia (50%). Grade 3/4 neutropenia was observed in one patient (5.6%). Among the non-hematologic toxicities, grade 1/2 hepatotoxicity was most common (22.2%), and grade 3/4 infection was observed in one patient (5.6%). There was no treatment-related mortality. CONCLUSION For patients with R/M HNSCC, a cisplatin and weekly docetaxel regimen showed high efficacy with tolerable toxicity as a first-line treatment.

Abstract
BACKGROUND The coexistence of malignancies in a patient may be explained by the tumor-to-tumor metastasis phenomenon or multiple primary malignant tumors, both of which are not common findings. Here, we are going to present a case with coexistent papillary thyroid carcinoma and primary squamous cell carcinoma of the lung. CASE PRESENTATION A 36-year-old Iranian man presented to our clinic for evaluation of constitutional symptoms. His past medical history was significant for papillary thyroid carcinoma due to which he had undergone total thyroidectomy, cervical lymph node dissection, and radioactive iodine therapy 14 years ago. Six months prior to admission, he received radioactive iodine therapy due to the metastatic involvement of both lungs with papillary thyroid carcinoma in another center with consequent improvement in symptoms. Diffuse nodular lesions in both lungs, a lesion in the lower lobe of his left lung, not present 6 months ago, peritoneal carcinomatosis, and several para-aortic lymphadenopathies were detected by imaging studies. A radioactive iodine uptake scan, positron emission tomography/computed tomography scan, and transbronchial biopsy of the lesion in the lung revealed concurrent squamous cell carcinoma of the lung and pulmonary metastasis of papillary thyroid carcinoma. After consultation with an oncologist, our patient received 6 months of chemotherapy; however, he died 8 months after presentation. CONCLUSIONS Physicians should be aware of the possibility of the emergence of primary malignancies in patients with a history of papillary thyroid carcinoma, especially lung cancer as it is a common site of papillary thyroid carcinoma metastases. Using appropriate diagnostic evaluations in order to choose the best therapeutic option is of utmost importance.

Abstract
INTRODUCTION Total rhinectomy is an uncommon procedure for the treatment of nasal malignancies, usually reserved for locally advanced tumors. There are few case series studying total rhinectomy in the literature, reporting conflicting results about recurrence and metastasis. OBJECTIVE Evaluate prognosis of total rhinectomy cases for malignant neoplasia in our institution. METHODS Retrospective review from January 2013 to September 2018, including all patients undergoing total rhinectomy in our Institution, under the care of the Head and Neck surgical team. RESULTS Ten patients were included, two men and eight women. The mean patient age was 71.6 years old. The majority had nasal skin (8 cases) carcinomas. Squamous cell carcinoma was present in seven cases. In total, six cases had regional metastasis, in a median period of 14.3 months. The overall mortality and disease specific mortality was 50% and 30%, respectively, in a median follow-up of 45.7 months. CONCLUSION We observed high overall and disease-specific mortality among cases with advanced nasal malignancies undergoing total rhinectomy.

Abstract
Objective: To analyze the prognosis and appropriate treatment modalities of the patients with recurrence of early stage (Ⅰb-Ⅱa) cervical squamous cancer primarily treated with radical hysterectomy. Methods: This retrospective study included patients with International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰb and Ⅱa recurrent cervical squamous cancer who underwent radical hysterectomy primarily from January 2007 to July 2015. Kaplan-Meier method and Cox regression analysis were performed to analyze related prognostic factors of overall survival and progression-free survival, which included age, postoperative therapy, the site of recurrence, therapy-free interval (TFI) and treatment modality. The patients who were treated with palliative chemotherapy after recurrence were selected as a subgroup. The responses of palliative chemotherapy were evaluated and analyzed among different factors, included TFI, the site of recurrence and chemotherapy regime. Results: Of the 2 071 patients, 116 relapsed Ⅰb-Ⅱa cervical squamous cancer were included in the study with the average age of (45.6±7.2) years old. 3-year progression-free survival rate and 3-year overall survival rate after recurrence were 30.2% and 42.2%, respectively. Univariate analysis implied that postoperative radiotherapy, recurrence site, TFI and treatment modality were associated with progression-free survival (P<0.05), while postoperative radiotherapy, TFI and treatment modality with overall survival (P<0.05). Multivariate analysis showed that TFI and treatment modality were independent prognostic factors for progression-free survival (P<0.05), while postoperative radiotherapy at initial treatment, TFI and treatment modality were independent prognostic variables for overall survival (P<0.05). In the analysis of treatment modality, 3-year progression-free survival rate and 3-year overall survival rate of 47 patients who were treated with definitive local therapy were significantly higher than that of 69 patients who were treated with palliative chemotherapy (P<0.01). In the subgroup analysis of palliative chemotherapy, 15 patients achieved complete response (21.7%) and 16 displayed partial response (23.2%). The overall response rate (ORR) was 44.9%. TFI (P<0.01) and chemotherapy regime (P<0.05) were significant factors associated with ORR. The ORR of TFI ≥12 months was significantly higher than that of TFI <12 months. Besides, the ORR of paclitaxel plus platinum chemotherapy was prominently higher than that of other regimens, while there was no significant difference between the ORR of paclitaxel plus cisplatin and other platinum (P=0.408). Conclusions: For recurrent stageⅠb-Ⅱa cervical squamous carcinoma treated with radical hysterectomy, use of definitive local therapy for suitable patients is advised to achieve better prognosis. In terms of palliative chemotherapy, longer TFI may mean better ORR and the combination of paclitaxel plus platinum is preferred.

Abstract
Laryngeal squamous cell carcinoma is one of the common head and neck cancers, and it ranks the second in the incidence of head and neck cancers. Smoking and alchol are considered the main causes of the disease in the past. Since 1982, when scholars first proposed that human papillonavirus(HPV) was associated with the development of laryngeal cancer, there have been a large number of studies on the correlation between HPV and laryngeal cancer, but the results are different. Therefore, this article summarizes the progress of related researches on the relationship between HPV and laryngeal cancer in recent years, and explores the impact of HPV on the treatment strategy of laryngeal cancer.
