“…2,3,7 In cases of clinically negative necks (N0), the clinical examination may present up to a 40% failure rate in detecting lymph node metastases. 2,3,8,9 A combination of clinical and imaging examinations is essential for detecting metastatic lymph nodes and establishing the prognosis. 10,11 Of the imaging modalities, computed tomography (CT) and magnetic resonance imaging (MRI) seem to be the most appropriate for the pre-therapeutic staging of head and neck tumors, because they provide information on the extent of the lesion, infiltration of large vessels and metastases in lymph nodes.…”

The aim of this study was to compare clinical staging and magnetic resonance imaging (MRI) staging for oral cancer, and to assess inter-observer agreement between oral and medical radiologists. A total of 10 patients diagnosed with oral cancer were assessed before treatment. A head and neck surgeon performed clinical TNM staging. Two medical radiologists and two oral radiologists performed a new staging assessment by interpreting MRI scans, without prior knowledge of the clinical staging. They evaluated the extent of the primary tumor (T), metastasis to regional lymph nodes (N) and grouping by stages. The data were analyzed using the Kappa Index. There was significant agreement (p < 0.05) between the clinical and MRI staging assessments made by one oral radiologist for N stage, and between those made by one medical radiologist for the T and N stages and for the grouping by stages. In the MRI assessment, there was significant agreement among all four observers for both T stage and grouping by stages. For the N stage, there was no significant agreement between one oral radiologist and one medical radiologist or between both medical radiologists. There was significant agreement among the remaining radiologists. There was no agreement between the clinical and MRI staging. These results indicate the importance of using MRI for the diagnosis of oral cancer. Training initiatives and calibration of medical and oral radiologists should be promoted to provide an improved multidisciplinary approach to oral cancer.

“…Some authors have demonstrated that over 20% of neck palpation-negative patients have indeed occult neck metastases. 10,11 Another important factor for accurately estimating survival is a long-term follow-up of patients with oral malignancies. 12 Local recurrent tumours following primary treatment are a relatively common occurrence after treatment, and are, sometimes, also not detected clinically.…”

Objectives:The aim was to verify the concordance of CT evaluation among four radiologists (two oral and maxillofacial and two medical radiologists) at the TN (tumour/node) stage and in the follow-up of oral cavity and oropharyngeal cancer patients. The study also compared differences between clinical and CT examinations in determining the TN stage. Methods:The following clinical and tomographic findings of 15 non-treated oral cavity and oropharyngeal cancer patients were compared: tumour size, bone invasion and lymph node metastases. In another 15 patients, who had previously been treated, a clinical and tomographic analysis comparison for the presence of tumoural recurrence, post-therapeutic changes in muscles and lymph node metastases was performed. The concordances of tomographic evaluation between the radiologists were analysed using the kappa index. Results: Significant agreement was verified between all radiologists for the T stage, but not for the N stage. In the group of treated patients, CT disclosed post-therapeutic changes in muscles, tumour recurrence and lymph node metastases, but no concordance for the detection of lymph node metastases was found between radiologists. In the first group, for all radiologists, no concordance was demonstrated between clinical and tomographic staging. CT was effective for delimitating advanced lesions and for detecting lymph node involvement in N0 stage patients. CT revealed two cases of bone invasion not clinically detected. Conclusions: Interprofessional relationships must be stimulated to improve diagnoses, and to promote a multidisciplinary approach to oral cavity and oropharyngeal cancer. Although CT was important in the diagnosis and follow-up of cancer patients, differences between medical and dental analyses should be acknowledged.

“…This outcome can also be affected by the operator's experience and judgement. Of 4.5% neck recurrences after selective neck dissection, Carvalho et al (2000) found 57.1% of them to be inside the limits of dissection. Similarly, Anderson et al (2002) and Chepeha et al (2002) reported two-thirds of recurrences following SOHND to be in the field of dissection.…”

Ipsilateral Neck Cancer Recurrences After Elective Supraomohyoid Neck Dissection

Abstract: The incidence of neck recurrence after selective neck dissection was 4.5%, and it occurred either inside (57.1%) or beyond (42.9%) the limits of the selective neck dissection.
