Overall survival by HPV status

• p16 is a good surrogate marker of HPV infection in oropharyngeal cancer

• Diagnosis and prognosis value of p16 outside the oropharynx is controversial

Different curative treatments depending on disease stage and location

Stage 1-2: - One single treatment modality: surgery or radiotherapy

Stage 3-4: - Multimodal treatment including surgery and/or (chemo)radiation

One third will present recurrent or metastatic disease

Squamous cell carcinoma of the head and neck

Treatment of locally advanced disease (stage 3-4)

Chemoradiation followed by neck dissection in case of suspected residual disease in the regional lymph node

Surgery followed by radiation therapy or chemoradiation(preferred approach for oral cavity)

Key messages

• Standard of care = Concomitant chemoradiation
