Accuracy of clinical examination versus computed tomography in detecting occult lymph node involvement in patients with oral epidermoid carcinoma

Accuracy of palpation, ultrasonography, and computed tomography in the evaluation of metastatic cervical lymph nodes in head and neck cancer

“…[ 5 ] Clinical palpation is the first line subjective method, and it is totally operator dependent and follows a learning curve with experience. The rates of determining the neck metastasis with only palpation were investigated by different authors, and the accuracy in our study was comparable to previous studies,[ 1 3 4 6 7 ] and literature gives a range of values from 60% to 80%. It is apparent from this and other studies that clinical examination is a poor, unreliable, inaccurate method to determine the presence of occult cervical lymph node involvement.…”

“…Literature suggests that the accuracy of USG ranges from 67% to 95%. [ 1 3 4 6 7 ] Though the specificity of US is lower than other methods, it has the highest sensitivity and high negative predictive value. Van den Brekel et al [ 8 ] suggested that the optimal size criterion for US assessment of cervical metastatic nodes varies with the patient population, and the most acceptable size criterion in minimal axial diameter is 9 mm for sub digastric nodes and 8 mm for other cervical nodes.…”

Accuracy of Computed Tomography in Determining the Presence or Absence of Metastatic Retropharyngeal Adenopathy

“…They used computed tomography (CT) alone to determine the presence of RPN adenopathy and found a 9% incidence of "radiologic" metastasis. They found a lower rate of regional disease control, a higher incidence of distant metastasis, and a lower 5-year diseasefree survival in these patients.While recent studies 5,6 have been done evaluating the ability of CT scanning and magnetic resonance imaging to detect metastatic cervical adenopathy involving lymph node levels 1 to 5, to our knowledge, no up-to-date study has yet …”

Validation of the Metastatic Formula: A Method of Cervical Lymph Nodes Assessment in Oral Cancer Patients

“…Techniques that in use for the assessment of cervical lymph nodes metastasis are, clinical palpation, imaging techniques such as CT, MRI, PET CT scan, SLN biopsy and ultrasound-guided fine needle aspiration cytology and all of them had been used to improve upon the results of clinical palpation alone. These diagnostic techniques showed less than 100% accuracy for neck metastasis and showed lower sensitivity and Somewhat lower specificity, thus the risk of occult disease in the neck will remain [10,[15][16][17][18][19].…”
