Evaluation of the N0 Neck
• The reported false negative rate in assessing of cervical LN metastasis by palpation is 20%-50%
• Factor affecting :• The experience of the examiner• The patient’s body• The previous treatment – Sx / RT
![Page 23: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/23.jpg)

• Structure in neck mistake• Transverse process of atlas• Carotid bifurcation• Submandibular gland
![Page 24: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/24.jpg)

Therapeutic modalities for the N0 neck
• Prophylactic Neck dissection• Prophylactic Neck irradiation• Observation with therapeutic ND once
regional metastasis become appearance
![Page 28: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/28.jpg)
The N0 neck in oral cavity CA
• Byers et al : the prediction of nodal metas. In primary oral tongue SCCA
• The depth of muscle invasion• N stage• The degree of differentiation of the 1˚ tumor
• T1N0 with muscle invasion < 4 mm., WD
14% chance of nodal involvement
![Page 29: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/29.jpg)
The N0 neck in oral cavity CA
• SCCA of oral cavity the sites with < 20% occult metastasis :
• T1/T2 lip• T1/T2 oral tongue < 4 mm in thickness• T1/T2 FOM < 1.5 mm in thickness
![Page 30: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/30.jpg)
Surgical therapy in the N0 neck with oral cavity CA
• SOHND• Minimal morbidity• Reduces the risk of occult disease• Avoid the undesirable side effect of RT
( RT is reserved for possible future tx. of second primary tumor )
![Page 31: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/31.jpg)
RT in the N0 neck with oral cavity CA
• An alternative treatment to SOHND • PORT of the surgically treated primary
tumor site, the neck has not been dissected, and the risk of occult regional dz. is substantial
• Primary tumor is treated with RT and the risk of occult node > 20%
![Page 32: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/32.jpg)
Elective neck dissection VS Elective neck irradiation
• ENI reduced neck failure rate in pt with control primary tumor and N0 neck from 18% to 1.9%
• In T1N0 SCCA oral tongue, ENI provided 95% control rate for neck recurrences compare with 38% without ENI
• Modality is chosen to Tx primary cancer may also help in formulating a decision as to how to tx the neck
![Page 33: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/33.jpg)
Elective neck dissection VS Elective neck irradiation
• Prophylactic neck RT provides equal control rate for neck metastasis to prophylactic ND

Combined modality of treatment
• perineural spread• intravascular spread• intralymphatic spread• + ve margin• 2 histo. Positive LN• multiple +ve LN• extracapsular spread

Management of contralateral N0
• 14% incidence of involvement of contralateral neck node regardless of tumor stage
• If primary oral cavity cancer is midline location, bilaterally, along the tip of tongue or approaches or cross the midline

N0 in early SCCA oral cavity
• Most important prognostic factor in Mx of oral SCCA is status of cervical LN.
• Present of metastasis to cervical LN can reduce curative rate by 50%
• 3 Tx options are available.• Observation with therapeutic ND once regional
metastasis become appearance• Elective neck RT • Elective neck dissection
![Page 43: INTER-HOSPITAL CONFERENCE](https://reader035.vdocuments.site/reader035/viewer/2022062315/568152f0550346895dc10adb/html5/thumbnails/43.jpg)
Morbidities of associated ENI
• Xerostomia • Dsyphagia• Increased oral passage time• Mucositis• Pain• Increased complication if salvage sx.• Long duration of tx.
