The secondary objectives will include 2-year loco-regional control and overall survival,
quality of life, and late toxicity. Quality of life outcomes can be assessed with a
validated, self-reported questionnaire. Late toxicity can be assessed using the National
Cancer Institute Common Terminology Criteria for Adverse Events. Additionally, the prognostic
value of positive HPV in salivary rinse as well as plasma at mid and post- treatment time
points will be evaluated with a baseline evaluation pre-treatment. Radiomic analysis of
pre-treatment imaging will be correlated with outcomes.
- Pathologically (histologically or cytologically) proven diagnosis of squamous cell
carcinoma of the oropharynx, which include the sites tonsil, base of tongue, soft
palate, or posterior oropharyngeal wall. Histologic variants will be included
(papillary squamous cell carcinoma and basaloid squamous cell carcinoma). Cytologic
diagnosis from a cervical lymph node is sufficient in the presence of clinical
evidence of a primary tumor in the oropharynx.
- Patient's tissue must be positive for p16 by immunohistochemical staining (>70%
staining). Fine needle aspiration (FNA) biopsy specimens may be used as the sole
diagnostic tissue if formalin-fixed paraffin-embedded cell block material is available
for p16 immunohistochemistry.
- Clinical stage T1-T2, N1-N2b or T3, N1-N2b (AJCC 7th Edition) with no distant
metastases based on the following diagnostic workup:
- Fiberoptic exam with laryngopharyngoscopy (mirror and/or fiberoptic and/or direct
procedure) within 8 weeks prior to registration.
- One of the following combinations of imaging is required within 8 weeks of
1. Or a CT scan of the neck (with contrast) and a PET/CT of neck and chest (with or
2. Or an MRI of the neck (with contrast) and a PET/CT of neck and chest (with or
3. Note: A CT scan of the neck and/or a PET/CT performed for the purposes of
radiation planning may serve as both staging and planning tools.
- Patients must provide their personal smoking history prior to registration. Patients
cannot have a cumulative personal smoking history that exceeds 10 pack-years.
1. Number of pack-years = [Frequency of smoking (number of cigarettes per day) x
duration of cigarette smoking (years)] / 20
2. Note: Twenty cigarettes is considered equivalent to one pack. Cigar and pipe
tobacco consumption is not included in calculating lifetime pack-years.
- Zubrod Performance Status of 0-1 within 8 weeks prior to registration;
- Adequate hematologic function within 2 weeks prior to registration, defined as
Absolute neutrophil count (ANC) ≥ 1,500 cells/mm3; Platelets ≥ 100,000 cells/mm3;
Hemoglobin ≥ 8.0 g/dl; Note: the use of transfusion or other intervention to achieve Hgb ≥
8.0 g/dl is acceptable.
- Adequate renal function within 2 weeks prior to registration, defined as follows:
a.Serum creatinine ≤ mg/dl or creatinine clearance (CC) ≥ 50 ml/min determined by 24
hour collection or estimated by Cockcorft-Gault formula: i.CCr male = [(140 - age) x
(wt in kg)] [(Serum Cr mg/dl) x (72)] ii.CCr female = 0.85 x (CrCl male)
- Negative serum pregnancy test within 14 days prior to registration for women of
- Patients who are HIV positive but who have no prior AIDS-defining illness and have CD4
cells of at least 350/mm3 are eligible. HIV-positive patients must not have multi-drug
resistant HIV infection or other concurrent AIDS-defining conditions. Patients must
not be sero-positive for Hepatitis B (Hepatitis B surface antigen positive or
anti-hepatitis B core antigen positive) or sero-positive for Hepatitis C
(anti-Hepatitis C antibody positive). However, patients who are immune to hepatitis B
(anti-Hepatitis B surface antibody positive) are eligible (e.g. patients immunized
against hepatitis B).
- The patient must provide study-specific informed consent prior to study entry.
- Cancers considered to be from an oral cavity site (oral tongue, floor of mouth,
alveolar ridge, buccal or lip), or the nasopharynx, hypopharynx, or larynx, even if
- Carcinoma of the neck of unknown primary site origin (even if p16 positive);
- Distant metastasis or adenopathy below the clavicles;
- Gross total excision of both primary and nodal disease; this includes tonsillectomy,
local excision of primary site, and nodal excision that removes all clinically and
radiographically evident disease.
- Simultaneous primary cancers or separate bilateral primary tumor sites;
- Prior invasive malignancy malignancy (except non-melanomatous skin cancer) unless
disease free for a minimum of 1095 days (3 years) (for example, carcinoma in situ of
the breast, oral cavity, or cervix are all permissible);
- Prior systemic chemotherapy for the study cancer; note that prior chemotherapy for a
different cancer is allowable;
- Prior radiotherapy to the region of the study cancer that would result in overlap of
radiation therapy fields;
- Severe, active co-morbidity defined as follows:
1. Unstable angina and/or congestive heart failure requiring hospitalization within
the last 6 months;
2. Transmural myocardial infarction within the last 6 months;
3. Acute bacterial or fungal infection intravenous antibiotics at the time of
4. Chronic obstructive pulmonary disease exacerbation or other respiratory illness
requiring hospitalization or precluding study therapy within 30 days of
5. Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects;
note, however, that laboratory tests for liver function and coagulation
parameters are not required for entry into this protocol other than those listed
6. Acquired immune deficiency syndrome (AIDS) based upon the current CDC definition
with immune compromise greater than that noted in section 4.1.12; note, however,
that HIV testing is not required for entry into this protocol. The need to
exclude patients with AIDS from this protocol is necessary because the treatments
involved in this protocol may be significantly immunosuppressive.
Protocol-specific requirements may also exclude immune-compromised patients.
- Pregnancy; this exclusion is necessary because the treatment in this study may be
- Prior allergic reaction to cisplatin.
- Exclusion Criteria for MRI: Normal MRI exclusion criteria will apply, including those
on the following list. A standard MRI safety form will be used to identify potential
conditions warranting exclusion.
- Electrical implants such as cardiac pacemakers or perfusion pumps
- Ferromagnetic implants such as aneurysm clips, surgical clips, prostheses, artificial
heart, valves with steel parts, metal fragments, shrapnel, bullets, tattoos near the
eye, or steel implants
- Ferromagnetic objects such as jewelry or metal clips in clothing
- History of seizures
- Diabetes a.In addition, patients with GFR < 15 ml/min/1.73m2 or who are on dialysis
will not have DCE-MRI scan. These patients will have conventional anatomical MRI
without contrast and DW-MRI,
