- Patient-reported neck and shoulder function (Phase II/III) [ Time Frame: From Baseline (Before surgery) to 6 months post-surgery ]Will be evaluated and compared using the Neck Dissection Impairment Index (NDII), a 10-item tool between the two treatment arms. It is assumed that a 7.5-point (change from Baseline to 6 months) between arm difference is clinically meaningful. The hypothesis of no between-arm difference in 6-month NDII scores will be tested using the ANCOVA model at one-sided significance level of 0.10. Point estimates and 95% confidence intervals (CIs) for the mean NDII scores at 6 months for each treatment arm and for the between-arm difference at 6-months based on the proposed model will be provided.
- Disease-Free Survival [ Time Frame: From randomization to local/regional recurrence, distant metastasis, or death due to any cause, whichever comes first, assessed up to 11 years ]An event for disease-free survival is local recurrence, regional recurrence, distant metastasis, or death due to any cause. Disease-free survival time is randomization date to the date of event or last known follow-up (censoring). Rates will be estimated using the Kaplan-Meier method and between-arm differences compared using the log-rank test.
- Overall Survival [ Time Frame: From randomization to death due to any cause, assessed up to 11 years ]An event for overall survival is death due to any cause. Overall survival time is randomization date to date of event or last known follow-up (censoring). Rates will be estimated using the Kaplan-Meier method and between-arm differences compared using the log-rank test.
- Loco-regional Failure [ Time Frame: From the time of randomization to the date of failure, date of precluding event, or last known follow-up date, assessed up to 11 years ]An event for local-regional failure is local or regional recurrence. Local-regional failure time is randomization date to date of event, precluding event, or last known follow-up (censoring). Rates will be estimated using the cumulative incidence method and between arm differences compared using cause-specific log-rank test.
- Distant metastasis [ Time Frame: From the time of randomization to the date of distant metastasis, date of precluding event, or last known follow-up date, assessed up to 11 years ]An event is the occurrence of distant metastasis. Distant metastasis time is randomization to date of event, precluding event, or last known follow-up (censoring). Rates will be estimated using the cumulative incidence method and between-arm differences compared using cause-specific log-rank test.
- Patient-reported shoulder-related QOL, function impairment and disability [ Time Frame: Baseline, 3 weeks, 3, 6, 12 months post-surgery. Analysis occurs at the same time as the primary endpoint. ]Patient reported using Abbreviated Disabilities of the Arm, Shoulder, and Hand (QuickDASH) with scores of 0-100. A higher score indicates greater disability.
- General quality of life [ Time Frame: Baseline, 3 weeks, 3, 6, 12 months post-surgery. Analysis occurs at the same time as the primary endpoint. ]Will be measured using the Functional Assessment of Cancer Therapy-Head and Neck (FACT-H&N) to measure Functional Assessment of Cancer Therapy-Head and Neck-Trial Outcome Index (FACT-TOI) scores on a scale from 0-96. A higher score indicates better quality of life.
- Nodal metastasis detection rate [ Time Frame: During surgery. Analysis occurs at the same time as the primary endpoint. ]Defined as the proportion of patients with pathologic positive nodes using the pathology results.
- Pathologic false omission rate [ Time Frame: During surgery. Analysis occurs at the same time as the primary endpoint. ]Measured within the sentinel lymph node biopsy (SLN) arm only. Defined as the proportion of patients with false negative results among negative SLN patients.
- Post-surgery patient-reported outcome [ Time Frame: At 6 months post-surgery. Analysis occurs at the same time as the primary endpoint. ]Measured by NDII in low-risk oral cavity squamous cell carcinoma patients using ANCOVA comparison model.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- PRIOR TO STEP 1 REGISTRATION INCLUSION:
- Pathologically (histologically or cytologically) proven diagnosis of squamous cell carcinoma of the oral cavity, including the oral (mobile) tongue, floor of mouth (FOM), mucosal lip, buccal mucosa, lower alveolar ridge, upper alveolar ridge, retromolar gingiva (retromolar trigone; RMT), or hard palate prior to registration
-
Appropriate stage for study entry (T1-2N0M0; American Joint Committee on Cancer [AJCC] 8th edition [ed.]) based on the following diagnostic workup:
- History/physical examination within 42 days prior to registration
-
Imaging of head and neck within 42 days prior to registration
- PET/CT scan or contrast neck CT scan, or gadolinium-enhanced neck magnetic resonance imaging (MRI) or lateral and central neck ultrasound; diagnostic quality CT is preferred and highly recommended for the PET/CT when possible.
- Imaging of chest within 42 days prior to registration; chest x-ray, CT chest scan (with or without contrast) or PET/CT (with or without contrast)
-
Surgical assessment within 42 days prior to registration. Patient must be a candidate for surgical intervention with sentinel lymph node (SLN) biopsy and potential completion neck dissection (CND) or elective neck dissection (END)
- Surgical resection of the primary tumor will occur through a transoral approach with anticipation of resection free margins
- Zubrod performance status 0-2 within 42 days prior to registration
- For women of child-bearing potential, negative serum or urine pregnancy test within 42 days prior to registration
- The patient or a legally authorized representative must provide study-specific informed consent prior to study entry
- Only patients who are able to read and understand English are eligible to participate as the mandatory patient reported NDII tool is only available in this language
- PRIOR TO STEP 2 RANDOMIZATION:
-
FDG PET/CT required prior to step 2. Note: FDG PET/CT done prior to step 1 can be submitted for central review.
- PET/CT node negative patients, determined by central read, will proceed to randomization.
-
PET/CT node positive patients will go off study, but will be entered in a registry and data will be collected to record the pathological outcome of neck nodes for diagnostic imaging assessment and future clinical trial development
- NOTE: All FDG PET/CT scans must be performed on an American College of Radiology (ACR) accredited scanner (or similar accrediting organization)
- The patient must complete NDII prior to step 2 registration
Exclusion Criteria:
- PRIOR TO STEP 1 REGISTRATION EXCLUSION:
- Definitive clinical or radiologic evidence of regional (cervical) and/or distant metastatic disease
- Prior non-head and neck invasive malignancy (except non-melanomatous skin cancer, including effectively treated basal cell or squamous cell skin cancer, or carcinoma in situ of the breast or cervix) unless disease free for ≥ 2 years
- Diagnosis of head and neck squamous cell carcinoma (SCC) in the oropharynx, nasopharynx, hypopharynx, and larynx
- Unable or unwilling to complete NDII (baseline only)
- 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
- Patient with severe, active co-morbidity that would preclude an elective or completion neck dissection
- Pregnancy and breast-feeding mothers
- Incomplete resection of oral cavity lesion with a positive margin; however, an excisional biopsy is permitted
- Prior surgery involving the lateral neck, including neck dissection or gross injury to the neck that would preclude surgical dissection for this trial. Prior thyroid and central neck surgery is permissible; biopsy is permitted. Note: Borderline suspicious nodes that are ≥ 1 cm with radiographic finding suggestive of NOT malignant should be biopsied using ultrasound-guided (U/S-guided) fine-needle aspiration (FNA) biopsy
- Underlying or documented history of hematologic malignancy (e.g., chronic lymphocytic leukemia [CLL]) or other active disease capable of causing lymphadenopathy (sarcoidosis or untreated mycobacterial infection)
- Actively receiving systemic cytotoxic chemotherapy, immunosuppressive, anti-monocyte or immunomodulatory therapy
- Currently participating in another investigational therapeutic trial
