ENID: Testing Less Intensive Radiation With Chemotherapy to Treat Low-risk Patients With HPV-positive Oropharyngeal Cancer
Study Details
Study Description
Brief Summary
This trial will explore giving standard dose chemotherapy and radiation therapy to sites of disease including all lymph nodes involved with HPV-positive oropharyngeal cancer, but administer lower doses of radiation therapy to the lymph nodes that are not known to be involved with cancer. By doing so, it is hypothesized that there will be equally good long term loco-regional and distant disease control but will reduced long term treatment side effects and improved quality of life in persons living well beyond their cancer treatment.

Detailed Description
This is a trial of definitive chemotherapy and radiation therapy in human papilloma virus positive oropharyngeal cancers, in a population whose cancer is thought to be highly radio-sensitive. This is a population whose outcomes are already known to be very good with high rates of local and distant control of the disease. With the long term disease control and survival of patients with this disease, long term treatment toxicity and resulting reduction in quality of life poses new problems. This has lead to several studies to examine the role of radiation dose de-escalation through various strategies in attempt to reduce long term toxicity from treatment and yet achieve equivalent long term disease control.
This trial specifically hypothesizes that a lower dose of radiation therapy to the clinically and radiographically uninvolved lymph nodes will no detrimental effect on loco-regional control or overall survival and will improve the long-term side effect profile, particularly with regards to xerostomia and dysphagia. The goal of this study is therefore to determine whether a lower dose to the clinically and radiographically uninvolved lymph nodes can be done safely and with better long-term toxicity profile and better overall quality of life without compromising the expected outcomes of progression free survival.

- Survival [At 6 months and at 2 years]
To determine overall survival and progression-free survival
- Toxicity profiles [1 year and 2 years post treatment]
Incidence of Common Terminology Criteria for Adverse Events (CTCAE) grade 2 or higher for mucositis, dysphagia, xerostomia and altered taste
- Hypothyroidism incidence [At 1 and 2 years post treatment]
To monitor rate of hypothyroidism
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Patients generally must have the psychological ability and general health that permits completion of the study requirements and required follow up.
-
Women of childbearing potential and men who are sexually active should be willing and able to use medically acceptable forms of contraception throughout the treatment phase of the trial and until at least 60 days following the last study treatment.
-
Pathologically (histologically or cytologically) proven diagnosis of squamous cell carcinoma (including the histological variants papillary squamous cell carcinoma and basaloid squamous cell carcinoma) of the oropharynx (tonsil, base of tongue, soft palate, or oropharyngeal walls); cytologic diagnosis from a cervical lymph node is sufficient in the presence of clinical evidence of a primary tumor in the oropharynx. Clinical evidence should be documented, may consist of palpation, imaging, or endoscopic evaluation, and should be sufficient to estimate the size of the primary (for T stage).
-
Patients must have clinically or radiographically evident measurable disease at the primary site or at nodal stations. Tonsillectomy or local excision of the primary without removal of nodal disease is permitted, as is excision removing gross nodal disease but with intact primary site. Limited neck dissections retrieving ≤ 4 nodes are permitted and considered as non-therapeutic nodal excisions.
-
Immunohistochemical staining for p16 must be performed on tissue and documented in the pathology report(s) with reported result positive for p16.
-
Clinical stage T1-T3, N0-N2c (AJCC, 7th ed.), which is equal to T1-T3, N0-2 (AJCC, 8th ed.) including no distant metastases based on the following diagnostic workup:
-
General history and physical examination within 30 days prior to registration;
-
Fiberoptic exam with laryngopharyngoscopy (mirror and/or fiberoptic and/or direct procedure) within 60 days prior to registration;
-
One of the following combinations of imaging is required within 45 days prior to registration:
-
A CT scan of the neck (with contrast) and a chest CT scan (with or without contrast);
-
or an MRI of the neck (with contrast) and a chest CT scan (with or without contrast);
-
or a CT scan of neck (with contrast) and a PET/CT of neck and chest (with or without contrast);
-
or an MRI of the neck (with contrast) and a PET/CT of neck and chest (with or without contrast).
Note: A CT scan of neck and/or a PET/CT performed for the purposes of radiation planning may serve as both staging and planning tools.
- Patients will be asked about their personal smoking history prior to enrollment. Only active smokers with greater than 10 pack years will be excluded from the trial. The total number of pack years will be collected at baseline. Current smokers who wish to discontinue will be offered smoking cessation information, and if they are able to discontinue smoking prior to initiation of radiation therapy, they can remain eligible for the trial.
Number of pack-years = [Frequency of smoking (number of cigarettes per day) × duration of cigarette smoking (years)] / 20 Note: Twenty cigarettes is considered equivalent to one pack. The effect of non-cigarette tobacco products on the survival of patients with p16-positive oropharyngeal cancers is undefined.
