How to Study for NEET SS Head and Neck Surgical Oncology

Core Knowledge Framework

Master the multidisciplinary evaluation principles and surgical decision-making algorithms that form the foundation of head and neck surgical oncology practice. 1, 2

Essential Clinical Competencies

Preoperative Assessment and Staging

• Focus on complete head and neck examination including mirror and fiberoptic nasopharyngolaryngoscopy of the entire upper aerodigestive tract (oral cavity, oropharynx, hypopharynx, larynx) with neck palpation 1
• Master interpretation of CT with contrast and/or MRI with contrast of primary site and neck, understanding when to add FDG-PET/CT (stage III-IV disease) 1
• Learn HPV testing protocols: p16 immunohistochemistry is the surrogate marker, requiring strong diffuse nuclear and cytoplasmic staining in ≥70% of tumor cells for HPV-positive classification 1
• Understand FNA biopsy technique for neck masses and when to escalate to core-needle biopsy (especially for cystic or highly necrotic lymph nodes with non-diagnostic FNA) 1, 2

Surgical Principles and Resectability Assessment

• Memorize criteria for unresectable T4b disease: pterygoid muscle involvement with severe trismus, gross skull base extension (pterygoid plate/sphenoid bone erosion, foramen ovale widening), superior nasopharynx extension, and carotid artery encasement 1
• Study margin adequacy requirements and the principle that surgical procedures should resect all gross tumor with adequate tumor-free margins 1
• Learn that surgical plans should not be modified based on response to neoadjuvant therapy except when tumor progression mandates more extensive resection 1

Neck Dissection Classification and Technique

Nodal Level Anatomy

• Master the anatomical boundaries of neck levels I-VI and their drainage patterns for different primary sites 3, 4
• Understand that suspicious lymph nodes on imaging show: rounded shape, loss of fatty hilum, heterogeneous architecture, necrotic centers, extracapsular extension, irregular borders, and size >1.5 cm 3

Surgical Decision Algorithm by N-Stage

• N0 disease: Selective neck dissection of levels II-IV (add level VI for infraglottic laryngeal/hypopharyngeal cancers); for oral cavity include levels I-III 4
• N1-N2 disease: Either selective or comprehensive neck dissection acceptable, though comprehensive generally preferred for therapeutic intent 4
• N3 disease: Comprehensive neck dissection mandatory 4
• Bilateral dissection indications: Midline tumors or sites with bilateral drainage (base of tongue, palate, supraglottic larynx, deep pre-epiglottic space involvement) 4

Treatment Paradigms by Stage

Early-Stage Disease (Stage I-II)

• Single-modality treatment with either surgery or radiation therapy yields similar survival 1, 2
• Choice depends on institutional expertise and perceived morbidity of treatment options 1

Advanced Disease (Stage III-IV)

• Combined modality therapy is standard 1, 2
• Understand indications for adjuvant radiotherapy: satellitosis, positive nodes, extracapsular spread 1
• Learn that concurrent chemoradiation carries high toxicity burden requiring experienced teams and substantial supportive care 1

Surveillance Protocols

Follow-up Schedule (Post-Treatment)

• Year 1: Every 1-3 months 1
• Year 2: Every 2-6 months 1
• Years 3-5: Every 4-8 months 1
• Beyond 5 years: Every 6-12 months 1

Imaging Recommendations

• Baseline imaging of primary and neck within 6 months post-treatment (category 2B recommendation) 1
• For oropharynx, hypopharynx, glottic/supraglottic larynx, nasopharynx: imaging recommended only for T3-4 or N2-3 disease 1
• Routine reimaging not recommended for asymptomatic patients 1

Additional Surveillance

• TSH every 6-12 months if neck irradiated 1
• Chest imaging as clinically indicated 1
• EBV monitoring for nasopharynx cancers 1

Special Populations and Scenarios

HPV-Positive Oropharyngeal Cancer

• Recognize distinct clinical presentation: younger patients, better prognosis 1, 2
• HPV-attributable fraction is 60-70% in US oropharyngeal cancers 1
• HPV16 is the predominant type, with types 18,31,33 responsible for most remaining cases 1

Differentiated Thyroid Cancer (T1-T3, N0-N1b without adverse features)

• Surgery can be delayed up to 12 weeks from diagnosis if necessary 1
• If surgery not possible within 12 weeks, use serial monitoring and only operate if clinically significant tumor progression 1
• Do not treat with radioactive iodine or radiotherapy as primary treatment if surgery delayed 1

Resource-Constrained Settings (e.g., COVID-19 pandemic)

• Early head and neck cancer: Can delay surgery 4 weeks; if 4-8 weeks delay anticipated, recommend radiotherapy immediately instead 1
• Advanced head and neck cancer: Do not delay surgery beyond 4 weeks; give alternative treatment immediately if surgery cannot occur within this timeframe 1

High-Yield Examination Topics

Risk Factors

• Tobacco use, alcohol abuse, oncogenic viruses (HPV, EBV) 2
• Age >40 years for squamous cell carcinoma 2

Prognostic Factors

• Margin status and depth of invasion are key histopathologic features 2
• Comorbidity is strong independent predictor for mortality 2

Quality of Life Considerations

• Head and neck cancers affect basic physiologic functions, senses, appearance, and voice 2
• Speech/hearing and swallowing evaluation and rehabilitation should be performed as clinically indicated 1
• Smoking cessation and alcohol counseling are essential components of follow-up 1

Study Strategy Recommendations

Focus on multidisciplinary decision-making algorithms rather than memorizing isolated facts, as head and neck surgical oncology requires integration of surgical, radiation, and medical oncology principles 1, 5. The NCCN guidelines emphasize that multidisciplinary evaluation must be coordinated prospectively before initiating any treatment 1.

Prioritize understanding surgical resectability criteria and when to offer alternative treatments, as this represents a critical decision point in patient management 1.

Master the TNM staging system with emphasis on how T stage (subsite involvement and size/extent), N stage (laterality, size, number), and M stage (distant metastases) correlate with treatment decisions and survival outcomes 2.
