Eligibility
Key inclusion criteria
- Age 18 years or older

- willing to provide informed consent

- ECOG performance status 0-2

- Histologically confirmed squamous cell carcinoma

- P16 positive, or HPV positive

- Primary tumor site in the oropharynx (includes tonsil, soft palate, base of tongue,
walls of oropharynx)

- Eligible for curative intent treatment, with likely negative resection margins at
surgery. For patients where adequate transoral access is in question, they will first
undergo an examination under anesthesia prior to randomization to ensure adequate
exposure can be obtained.

- Smokers and non-smokers are included. Patients will be stratified by ,<10 pack years
smoking history versus > or equal to 10 pack years.

- Tumor stage (AJCC 8th edition): T1 or T2

- Nodal stage (AJCC 8th edition): N0, N1, or N2

- For patients who may require chemotherapy (ie, patients with multiple lymph nodes
positive or a single node more than 3 cm in size, in any plane, CBC/differential
within 4 weeks prior to randomization with adequate bone marrow function, hepatic, and
renal function defined as: Hemoglobin = 80 g/L; Absolute neutrophil count = 1.5 x 10
9/L, platelets = 100 x 10 9/L, bilirubin = 35 umol/L, AST or ALT = 3 x the upper limit
of normal; serum creatinine = 130 umol/L or creatinine clearance = 50 ml/min

- patients assessed at head and neck multidisciplinary clinic (with assessment by
radiation oncologist and surgeon) and presented at multidisciplinary tumor board prior
to randomization
Minimum age
18 Years
Maximum age
No limit
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- unambiguous clinical or radiological evidence of extranodaal extension on
pre-treatment imaging. This includes the presence of matted notes, defined as 3 or
more nodes that are abutting with loss of intervening fat planes

- Serious medical comorbidities or other contraindications to radiotherapy, chemotherapy
or surgery

- prior history of head and neck cancer within 5 years

- prior head and neck radiation at any time

- metastatic disease

- inability to attend full course of radiotherapy or follow up visits

- prior invasive malignant disease unless disease-free for at least 5 years or more,
with the exception of non-melanoma skin cancer

- pregnant or lactating women

Summary
Brief summary
The goal of this randomized treatment de-escalation study is to formally compare outcomes in
HPV related oropharyngeal cancer tumors treated with a primary radiotherapy versus a primary
surgical approach, to provide a high level of evidence to guide the selection of treatment
options for a subsequent phase III trial
