Preservation of Swallowing in Respected Oral Cavity Squamous Cell Carcinoma: Examining Radiation Volume Effects (PRESERVE): A Randomized Trial
Preservation of Swallowing in Resected Oral Cavity Squamous Cell Carcinoma: Examining Radiation Volume Effects: A Randomized Trial
London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's
90 participants
Sep 6, 2019
INTERVENTIONAL
Conditions
Summary
The goal of this randomized treatment study is to formally compare quality of life in patients with at least one pN0 hemi-neck after resection of a squamous cell carcinoma of the oral cavity treated with a primary radiation therapy versus a secondary targeted radiation therapy approach, to provide a high level of evidence to guide the selection of treatment options.
Eligibility
Inclusion Criteria5
- Willing to provide informed consent
- ECOG performance status 0-2
- Histologically confirmed, resected oral cavity squamous cell carcinoma with at least ipsilateral selective neck disection
- Patient has pathological features that are indications for PORT: positive or close (≤ 3 mm) margin, presence of LVI or PNU, pT3 or pT4 disease, positive lymph nodes, and PORT is recommended by treating physician
- Pathologically lympth node negative in at least one dissected hemi-neck with at least 10 nodes recovered in each pN0 hemi-neck
Exclusion Criteria10
- Serious medical comorbidities or other contraindications to radiotherapy
- Prior history of head and neck cancer within 5 years
- Any other active invasive malignancy, except non-melanotic skin cancers
- Prior head and neck radiation at any time
- Prior oncologic head and neck surgery in the oral cavity or neck
- Metastatic disease
- Locoregional disease recurrence identified following surgical resection but prior to the start of radiotherapy
- Inability to attend full course of radio therapy or follow-up visits
- Unable or unwilling to complete QoL questionnaires
- Pregnant or lactating women
Interventions
Post operative radiation therapy +/- chemotherapy based on historic treatment volumes (including the primary site, dissected areas +/- elective areas
post operation radiation therapy +/- chemotherapy that avoids targeting the dissected pN0 neck
