Serum Tumour

Background: The delay in diagnosis of oral squamous cell carcinoma (OSCC) is a factor in rendering the poor prognosis, and recent research has explored the use of serum tumour markers such Beta 2 Microglobulin (B2M), to aid early diagnosis. However, despite a high incidence of OSCC in Southeast Asia, no studies on the clinical use of B2M in the region were found. Objectives: To determine if serum B2M level can serve as an initial diagnostic tool to indicate if a biopsy is warranted, and if so, to propose a local B2M serum reference value to identify OSSC patients. Methodology: Twenty-one patients were seen at Hospital Universiti Sains Malaysia (HUSM) for a one-year period, between June 2016 and June 2017, and equal number of healthy controls participated in the study. Apart from patient history, venous blood of approximately 5ml volume was collected from each subject at the pre-treatment stage and analysed by an Abbot ARCHITECT c8000 analyser using the immunoturbidimetry method. The results were analysed using ROC analysis and the Mann Whitney test. Results: Serum B2M levels showed a statistically significant increase (p<0.001) in patients compared to controls. The test was shown to have 90.5% sensitivity and 90.5% specificity. It was found to be a sensitive and specific serum tumour marker at a cut off value of 1.57mg/l to differentiate cases from controls. Conclusion: B2M is a sensitive and specific tumour marker to differentiate OSCC cases from controls. It is cost effective and minimally invasive, making it a potentially useful adjunct diagnostic tool in a high-risk patient pool. Bangladesh Journal of Medical Science Vol.18(4) 2019 p.729-735

Malignancy Grading

Squamous cell carcinoma is the most important and the most common malignant mucosal neoplasm of the head and neck accounting for over 90% of all malignancies. Conventional oral Squamous cell carcinoma is frequently present in general cancerous conditions. It is bundled up with six different variants. Histomorphologically every variant shows a unique appearance. This raises an opportunity for the different diagnostic consideration with the precise management decision.All cases of OSCC reported at our institution Dentopath Pathologies Amravati in past two months were scrutinized. Representative sections containing the full thickness of the tumor were used for histopathological grading. The structure and identification of carcinomas were done microscopically by two expert dentopathologist.In the present study, we screened 100 slides of a conventional epithelial cell carcinoma. Amonst which 30 Slides showed the verrucous carcinoma. On 5 slides adenoid squamous cell carcinoma were observed. Incidence of Papillary squamous cell carcinoma and basaloid squamous cell carcinoma was only 1 out of 100 slides each. Whereas, the spindle cell/sarcomatoid carcinoma was observed on 2 slides. Adenosquamous carcinoma is the rarest variant and hence no incidence of this carcinoma were observed in our study. The behavior of the OSCC varies amongst due to the presence of different morphological type of tumor. A few studies on OSCC malignancy grading with different clinical parameters were made. In the present study different types of variants are seen according to their histopathological appearances.Histopathological knowledge is very important for the precise diagnosis. Squamous cell carcinoma is the most common neoplasm of oral cavity. However, variants of the same show very less frequency. Hence, it became challenge for the appropriate diagnosis as many times a misdiagnosis affects the course of treatment of the patient

Cervical Lymph Nodes

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.
