Objective: To evaluate the diagnostic accuracy of multislice computed tomography (CT) in detection of squamous cell carcinoma (SCC) of oral cavity in clinically suspected patients taking histopathology as gold standard. Material and Methods: This cross-sectional study has been conducted at Radiology department of Civil Hospital Karachi from 8th September 2018 to March 2019. All the cases having suspected oral squamous cell carcinoma and either of gender were included. Patients underwent computed tomography by using multislice scanner. Then patients undergone biopsy sampling and patients were labeled as positive or negative for squamous cell carcinoma of oral cavity on MDCT and histopathology. Sensitivity, specificity, and diagnostic accuracy of multislice CT for squamous cell carcinoma of oral cavity were measured taking histopathology as gold standard. Results: Total 168 cases were studied and out of them males were 76.8% and females were 23.2%. Mean gutka addiction history was 11.52±5.21 years. Mean lesion size on CT scan was 2.44±1.43 cm. In our study, 35.1% patients were diagnosed positive by multislice computed tomography and 43.5% through histopathology. Sensitivity, Specificity, PPV, NPV and accuracy were 86.4%, 79.8%, 69.9%, 91.6%, and 82.1% respectively. Conclusion: Multislice CT observed to be the effective diagnostic tool for the detection of SCC of oral cavity. Keywords: Multislice Computed Tomography, cancer, Oral Cavity

Abstract Objectives: To evaluate the diagnostic accuracy of contrast enhanced CT scan to detect cervical nodal metastasis in oral cavity squamous cell carcinoma keeping final histopathology as gold standard. Methods: Cross sectional study conducted from 1st January 2015 - 31st October 2016. All patients undergoing surgery who had their CT scans done at our centre were included in the study. Diagnostic accuracy of CT scans was calculated using final histopathology as gold standard. All CT scan were reviewed by consultant radiologist. Results: Total 100 patients were reviewed, 70% were female, 55% had buccal and 32% had tongue cancer. 11 cases of T1, 20 cases of T2 , 4 cases of T3 and 21 cases of T4 stages were staged similarly by CT scan and histopathology, the kappa value of38.8%, p value <0.01. 6 cases of N1, 1 case of N2a , 9 cases of N2b, 3 cases of N2c, 1 case of N3 and 29 cases of N0 stages were staged similarly by CT scan and histopathology, with kappa value of 28.1%, p value of  <0.01. Sensitivity, specificity, positive predictive value, negative predictive value and overall diagnostic accuracy were 83%,61%,70.9%,76.3% and 73% respectively. Conclusion: CT scan is useful for preoperative staging of oral cavity squamous cell carcinoma with an overall diagnostic accuracy of 73%, currently there are no superior diagnostic modalities. However, Due to low specificity and negative predictive value elective neck dissection should still be done in a negative CT scan for cervical lymph node metastases. Keywords: Oral Cavity,

Background: Oral squamous cell carcinoma which occurs closely to the mandible has a tendency to invade mandible. An accurate preoperative evaluation of mandibular invasion is important for optimum treatment planning. Aim of this study is to determine the accuracy of CBCT in detection of mandibular invasion in oral squamous cell carcinoma. Study design: In this prospective observational study 35 patients of histologically proven squamous cell carcinoma which was close proximity to the mandible were selected. The results of preoperative CBCT scan of mandible were compared with that of post operative histopathology of bone and thus sensitivity, specificity, negative predictive value, positive predictive value were calculated. Results: Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of CBCT were 96%, 90.90%, 96%, 90.90%, 97.14% respectively (Chi squared with Yates correction equals 21.844 with 1 degrees of freedom, p value < o.oooo1). Conclusion: Cone beam computed tomography is a sensitive test and has an acceptable range of specificity. Update Dent. Coll. j: 2018; 8 (2): 18-22

Background and Goals.This study aimed to investigate the diagnostic accuracy of magnifying endoscopy with narrow band imaging (ME-NBI) and determine its value for invasion depth staging in esophageal squamous cell carcinoma.Methods. We searched the PubMed, Embase, and Cochrane Library databases and found relevant studies published up to December 2016. Quality Assessment of Diagnostic Accuracy Studies 2 was used to evaluate the quality of the studies. We calculated sensitivity, specificity, and positive and negative likelihood values from forest plots and determined summary receiver operating characteristic (sROC) curves for ME-NBI diagnostic accuracy analysis.Results. Ten studies met our criteria and were selected for this meta-analysis. A total of 1,033 patients underwent ME-NBI, and 207 of these patients received a diagnosis of staging mucosal or submucosal invasion. The pooled sensitivity, specificity, and positive and negative likelihood values of ME-NBI for the diagnostic rate were 0.90 (95% CI, 0.71–0.97), 0.90 (95% CI, 0.80–0.95), 6.74 (95% CI, 3.52–712.89), and 0.20 (95% CI, 0.10–0.42), respectively. The area under the curve (AUC) was 0.95 for all studies.Conclusions. ME-NBI provides a high diagnostic rate in evaluating the esophagus to diagnose squamous cell carcinoma. In the differentiation for invasion depth staging, ME-NBI was demonstrated to be superior to white light endoscopy and had a similar diagnostic rate compared with HF-EUS. However, HF-EUS had high positive likelihood values for invasion depth staging, suggesting that HF-EUS is a reliable method for confirming invasion depth staging.

Objectives To determine the levels of carbohydrate antigen 125 (CA125) and tissue polypeptide-specific antigen (TPS) in saliva of patients with oral squamous cell carcinoma (OSCC) and patients with nonneoplastic disease of the oral cavity, and to investigate their diagnostic value and their relationship with pathological grade and clinical stage. Methods A total of 97 hospitalized patients with OSCC, 36 patients with nonneoplastic disease of the oral cavity and 50 healthy individuals were included in this investigation. Mixed saliva was collected from these patients and the healthy controls before treatment. Saliva samples were analyzed by enzyme-linked immunosorbent assay (ELISA). Results The saliva CA125 and TPS concentrations were significantly higher in patients with OSCC than in patients with nonneoplastic disease and healthy controls, but not significantly different between patients with nonneoplastic disease and controls. Neither the saliva CA125 nor the TPS level was correlated with pathological grade and clinical stage. The sensitivity, specificity and accuracy of saliva CA125 and TPS for the diagnosis of OSCC were 80.0%, 66.0%, 75.7%, and 82.1%, 74.0%, 79.3%, respectively. When CA125 and TPS were analyzed independently, there was no significant difference in sensitivity, specificity and accuracy between the two markers. When CA125 and TPS were analyzed in combination, there was no significant difference in sensitivity, specificity and accuracy between independent detection and combined detection. Conclusions The saliva CA125 and TPS concentrations were elevated in patients with OSCC. CA125 and TPS may prove to be useful tumor markers in OSCC.
