About this trial

This phase II trial examines the use of blood-based biomarkers is to help inform decision making for treatment and radiation therapy for patients with human papillomavirus (HPV) positive oropharyngeal squamous cell cancers. The standard treatments for head and neck cancers are radiation therapy with chemotherapy or surgery potentially followed by radiation therapy with or without chemotherapy. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving chemotherapy along with radiation may kill more tumor cells. However, the cancer can recur or can spread to other parts of the body and all treatments can be associated with side effects. The purpose of this study is to evaluate a blood-based biomarker, using the NavDx testing device, for head and neck cancers in order to see if it can help improve selection of the intensity of treatment in order to best balance the side effects of treatment with the goal of decreasing cancer recurrence. This test could aid in early detection of recurrence and salvage therapy.

Trial outcomes

Primary outcomes

1

Progression-free survival (PFS)

Progression-free survival (PFS), the time from treatment initiation until disease progression or worsening. PFS at specific timepoints will be estimated using Kaplan-Meier methodology.

Time frame
From registration to the first of either disease progression/recurrence or death, assessed up to 5 years

Secondary outcomes

1

Progression-free survival (PFS) follow-up

Progression-free survival (PFS) is defined as the time from treatment initiation until disease progression or worsening. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response versus (vs.) no response), we'll use logistic regression models.

Time frame
At years 1, 2, 3, 4, and 5
2

Disease-free survival (DFS)

Disease-free survival (DFS) is the measure of time after treatment during which no sign of cancer is found. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
From time of surgery and also from end of all treatment across all the groups, assessed up to 5 years
3

Overall survival (OS)

Overall survival (OS) is defined as the duration of patient survival from the time of treatment initiation. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
At years 1, 2, 3, 4, and 5
4

Patient reported outcomes (PROs)

Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
Up to 5 years

Other outcomes

1

ctHPVDNA detectability

Due to the limited sample size, these analyses will be hypothesis generating and descriptive in nature. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
At post-operative day 1 or 2
2

Salivary ctHPVDNA analysis for recurrence risk and surveillance

Salivary samples will be analyzed pre-treatment, post-op, and at the time of recurrence to determine whether salivary ctHPVDNA may further inform recurrence risk and surveillance in HPV(+) oropharyngeal squamous cell carcinoma. Due to the limited sample size, these analyses will be hypothesis generating and descriptive in nature. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
Up to 5 years
3

Characterization of post-operative drain fluid

We will characterize post-operative drain fluid and compare rates of detectability to blood and saliva in order with the aim to determine whether the regional drain represents a separate regional compartment for analysis. Due to the limited sample size, these analyses will be hypothesis generating and descriptive in nature. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
Up to 5 years
4

Quantification of pre-treatment imaging

We will prospectively quantify pretreatment imaging for number of involved nodes, radiographic extranodal extension as it relates to pathologic findings and risk of recurrence. Due to the limited sample size, these analyses will be hypothesis generating and descriptive in nature. Descriptive statistics will be summarized and the exploratory data will be correlated with clinical endpoints (PFS, time-to-progression, etc.). For time-to-event data, the Kaplan-Meier method will be used. For categorical data, we'll use the Fisher's exact test. For biomarker data used to predict binary outcomes (i.e. response vs. no response), we'll use logistic regression models.

Time frame
Up to 5 years
