Squamous Cell Carcinoma Tongue

ABSTRACTBackground: Squamous Cell Carcinoma (SCC) is the most common case of oral cancer which often occurs laterally on the tongue and rarely develops on the dorsal surface of the tongue. More than half of the cases are diagnosed late, thereby reducing the survival rate of the patients. Objective: This report was intended as an evaluation for the management of squamous cell carcinoma under multidisciplinary approach between oral surgery and other departments, as well as the provision of further post-operative treatment. Case Report: The author presents a case of 68-years-old female patient with a lump and an ulcer on her tongue. Around six months prior to the visit, patient complained of tongue ulcer followed by the emergence of a lump in a size of a corn seed. The lump was gradually enlarged with constant widening of the ulcer. Pain on the tongue was also perceived. The patient was then referred to Hasan Sadikin Hospital for further treatment. Case Management: Patients underwent hemiglossectomy and Selective Neck Dissection (SND) surgical procedures performed by Oral and Maxillofacial Surgeon in collaboration with Surgical Oncologist. Furthermore, after surgery, the patient was consulted to the Hemato-Oncology Division of Internal Medicine Department for chemotherapy treatment. Conclusions: The exact diagnosis was made based on the histopathological biopsy results of the tongue tissue. Management of tongue cancer must be done multidisciplinary. Some things that must be considered in handling such cases are the eradication of the tumor, the return of oral cavity function, and the aesthetic/functional aspects of the patient. Keywords: Oral cancer, Squamous cell carcinoma, Tongue cancer

Oral cancer, the most challenging and life threatening disease in the field of dentistry, may start as a reactive lesion due to constant stimulus from tobacco consumption, transform into a pre-malignant lesion (dysplastic lesion) and ultimately develop into a cancerous lesion (Invasive carcinoma). There is a fundamental revolution taking place in the analyzing methods; extraction of biological protein from the saliva rather than from tissues or blood. Several of the biomarkers have been studied with pro-carcinogenic effects like Interleukins (ILs), tumor necrosis factor (TNF) and leptin, but only a few have been stated in the literature, which show anti-cancer characteristics like adiponectin and zinc alpha-2 glycoprotein. This review explored the diagnostic and prognostic values of a biomarkers zinc alpha-2 glycoprotein (ZAG) in adults suspected of oral squamous cell carcinoma (OSCC). The PubMed, EMBASE and Google Scholar were searched for scientific studies reported on the potential mechanism of zinc alpha-2 glycoprotein. All the research articles were selected in which ZAG is applied solely or in conjunction with other biomarkers in oral cancer and other cancers. These literatures were carefully assessed to find out and compile the diagnostic and prognostic values and to inquire therapeutic action of ZAG in the process of carcinogenesis.

AbstractC18 ceramide plays an important role in the occurrence and development of oral squamous cell carcinoma. However, the function of ceramide synthase 1, a key enzyme in C18 ceramide synthesis, in oral squamous cell carcinoma is still unclear. The aim of our study was to investigate the relationship between ceramide synthase 1 and oral cancer. In this study, we found that the expression of ceramide synthase 1 was downregulated in oral cancer tissues and cell lines. In a mouse oral squamous cell carcinoma model induced by 4-nitroquinolin-1-oxide, ceramide synthase 1 knockout was associated with the severity of oral malignant transformation. Immunohistochemical studies showed significant upregulation of PCNA, MMP2, MMP9, and BCL2 expression and downregulation of BAX expression in the pathological hyperplastic area. In addition, ceramide synthase 1 knockdown promoted cell proliferation, migration, and invasion in vitro. Overexpression of CERS1 obtained the opposite effect. Ceramide synthase 1 knockdown caused endoplasmic reticulum stress and induced the VEGFA upregulation. Activating transcription factor 4 is responsible for ceramide synthase 1 knockdown caused VEGFA transcriptional upregulation. In addition, mild endoplasmic reticulum stress caused by ceramide synthase 1 knockdown could induce cisplatin resistance. Taken together, our study suggests that ceramide synthase 1 is downregulated in oral cancer and promotes the aggressiveness of oral squamous cell carcinoma and chemotherapeutic drug resistance.

Suspicious Lesions

Oral cancer is a significant cause of morbidity and mortality worldwide. In this article we present two cases of potentially innocuous looking lesions, initially thought to be traumatic in origin, but later diagnosed as cancer. The first patient presented with a persistent laceration thought to be caused by an accidental shaving injury, which was subsequently diagnosed as squamous cell carcinoma. The second patient presented with a hyperplastic mucosal lesion, suspected as forming due to denture-clasp irritation, which was subsequently diagnosed as proliferative verrucous carcinoma. The importance of early detection and palpation of suspicious lesions is emphasised in this article.

Abstract Distant small bowel metastases from head and neck squamous cell carcinomas are extremely rare, and tongue cancer metastasizing to the small bowel has not been previously reported. We describe a 40-year-old male patient who underwent subtotal gross laryngectomy for squamous cell carcinoma of the tongue in February 2007 and then presented in November 2008 with severe abdominal pain. Abdominal computed tomography (CT) and X-rays revealed free air, suggesting intestinal perforation. Emergency surgery revealed a 10-mm perforation at the ileum and a palpable hard tumor at the perforation site. The ileum was resected, and pathologic findings showed squamous cell carcinoma at the perforation site, which was consistent with metastasis from tongue cancer.

Oral cancer is one of a major health problem in some parts of the world especially in the developing countries. Oral cancer is the sixth most common cancer in the world whereas in India it is one of the most prevalent cancer. Oral cavity lesions are usually asymptomatic. Accurate diagnosis of the lesion is the first step for the proper management of patients and histopathology is considered as the gold standard. The objective is to study the different patterns of oral cavity lesions seen in a tertiary care hospital of Jammu: One year retrospective study. Post graduate department of pathology.: It was a retrospective study carried out in a tertiary care centre for a period of one year from March 2020 to Feb 2021. 148 cases of oral cavity lesions were included in this study. The parameters that were included in the study were sociodemographic data, site of the lesion, clinical features and histological diagnosis. Data collected was analysed.148 cases of oral lesions were identified during the period of study. The age of patients varied from 5 to 78years and Male to Female ratio was 2.2:1. Buccal mucosa (30%) was the most common site involved which was followed by tonsil (19%). Out of 148 cases 70 cases were malignant, 10 cases pre malignant and 21 cases were benign. Squamous cell carcinoma (33.7%) was the most common lesion present in our study. Oral cavity lesions have a vast spectrum of diseases which range from tumour like lesions to benign and malignant tumours. Our study concluded that squamous cell carcinoma was the most common malignant lesion of oral cavity. Histological typing of the lesion is important for confirmation of malignancy and it is essential for the proper management of the patient.

Background The X-linked tumor suppressor gene LDOC1 is reported to be involved in oral cancer. The detection of biomarkers in salivary RNA is a non-invasive strategy for diagnosing many diseases. The aim of the present study was to investigate the potential of salivary LDOC1 as a biomarker of oral cancer. Methods We determined the expression levels of LDOC1 in the saliva of oral squamous cell carcinoma (OSCC) subjects, and investigated its correlation with various clinicopathological characteristics. The expression levels of salivary LDOC1 were detected in 53 OSCC subjects and 43 healthy controls using quantitative reverse transcription polymerase chain reaction (qRT-PCR) analysis. We used Fisher’s exact test to analyze the correlations between expression levels and clinicopathological characteristics. Results Salivary LDOC1 was significantly upregulated in females with OSCC (p = 0.0072), and significantly downregulated in males with OSCC (p = 0.0206). Eighty-nine percent of male OSCC subjects who smoked expressed low levels of LDOC1. OSCC cell lines derived from male OSCC subjects expressed low levels of LDOC1. Conclusions A high level of salivary LDOC1 expression is a biomarker of OSCC in females. A high percentage of male OSCC subjects who smoke express low levels of salivary LDOC1. A low level of salivary LDOC1 expression is a biomarker of OSCC in males.

Protein Biomarkers

Most cases of oral squamous cell carcinoma (OSCC) develop from visible oral potentially malignant disorders (OPMDs). The latter exhibit heterogeneous subtypes with different transformation potentials, complicating the early detection of OSCC during routine visual oral cancer screenings. To develop clinically applicable biomarkers, we collected saliva samples from 96 healthy controls, 103 low-risk OPMDs, 130 high-risk OPMDs, and 131 OSCC subjects. These individuals were enrolled in Taiwan’s Oral Cancer Screening Program. We identified 302 protein biomarkers reported in the literature and/or through in-house studies and prioritized 49 proteins for quantification in the saliva samples using multiple reaction monitoring-MS. Twenty-eight proteins were successfully quantified with high confidence. The quantification data from non-OSCC subjects (healthy controls + low-risk OPMDs) and OSCC subjects in the training set were subjected to classification and regression tree analyses, through which we generated a four-protein panel consisting of MMP1, KNG1, ANXA2, and HSPA5. A risk-score scheme was established, and the panel showed high sensitivity (87.5%) and specificity (80.5%) in the test set to distinguish OSCC samples from non-OSCC samples. The risk score >0.4 detected 84% (42/50) of the stage I OSCCs and a significant portion (42%) of the high-risk OPMDs. Moreover, among 88 high-risk OPMD patients with available follow-up results, 18 developed OSCC within 5 y; of them, 77.8% (14/18) had risk scores >0.4. Our four-protein panel may therefore offer a clinically effective tool for detecting OSCC and monitoring high-risk OPMDs through a readily available biofluid.
