Background: Carcinoma of oral tongue is the most common oral cancer and because of its structure and function is prone for early local and regional spread of cancer. The final outcome of a primary tongue carcinoma patient depends upon various prognostic factors like thickness of tumor, depth of invasion, size of lesion and neck node 67metastasis. Risk of metastasis and spread to neck nodes increases with increase in tumor thickness Methods: This prospective observational study was carried out in the Department of Otolayngology- Head & Neck Surgery, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka for 18 months. Thirty patients with early oral tongue carcinoma i.e.T1 & T2 as per UICC and AJC criteria were included in this study by purposive non-randomized sampling technique. Result of the study were expressed as mean, standard deviation (+SD), frequency and percentages. Unpaired Student’s t-test and Pearson’s correlation co-efficient (r) test were performed. Results: Result of the study showed the mean (+SD) thickness of the tumor was 3.62 (+1.46) mm. Minimum thickness 1.1mm and maximum thickness 7.8mm. Only 21 (70%) subjects neck node were metastasized from tongue and mean (+SD) tumor thickness of the positive neck node metastasis was 5.54 (+1.07) mm and negative neck node metastasis was 2.87 (+0.75) mm. This indicated a significant difference between the groups. Pearson’s correlation co-efficient r (+0.981) which indicated tumor thickness was positively correlated with neck node metastasis. Conclusion: Tumor thickness of the early oral carcinoma positively correlated with neck node metastasis. Correlation between thickness and metastatic lymph node can help planning the treatment regimen and indicate the disease prognosis. Bangladesh J Otorhinolaryngol; April 2021; 27(1): 25-35
Background: Fine-needle aspiration cytology (FNAC) is recommended as a decisive diagnostic step in the workup of patients with nodular thyroid disease. Unfortunately, FNAC can miss malignancies in smaller and deeper nodule. Ultrasound guided FNAC (US-FNAC) can reduce this error in suspicious thyroid nodule. Objectives: To find out the correlation of USG guided FNAC with postoperative histopathology in diagnosis of thyroid nodule. Methods: After obtaining clearance and approval from Institutional Review Board, all 45 patients of thyroid nodule who were admitted in the Department of Otolaryngology – Head & Neck surgery of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka from April 2017 to August 2018 and had fulfilled the inclusion and exclusion criteria were selected for the study. Each patient was assessed before surgery by USG guided FNAC and post operatively by histopathology. Results: In this study mean age of the respondents was 33.33 yearswith SD±10.84. Male female ration was 1:5.4. USG guided FNAC was reported by ‘The Bethesda System for Reporting Thyroid Cytopathology’ (TBS-RTC).Of the 45 specimens 2 samples were nondiagnostic or unsatisfactory (Class I), 26 samples were benign (Class II), 2 samples were showing Atypia of Undetermined Significance or Follicular lesion of Undetermined Significance (Class III), 6 were showing follicular neoplasm or suspicious for a follicular neoplasm (Class IV), 5 samples were suspicious for malignancy (Class V) and 4 samples were positive for malignancy (Class VI). On comparison of ultrasound guided FNAC with histopathology the sensitivity for correct diagnosis was 94%, specificity was 93%, positive predictive value was 88%, negative predictive value was 96% and accuracy was 93%. Pearson’s correlation coefficient was 0.85 which is very strong for positive relationship. Conclusion: USG guided FNAC is the most accurate method for diagnostic evaluation of thyroid nodules.
