Removing the Planning Tumor Volume From Radiation Therapy for the Treatment of Head and Neck Squamous Cell Carcinoma
Pilot Study of the Elimination of Planning Tumor Volume (PTV) in Head and Neck Squamous Cell Carcinoma (HNSCC)
This clinical trial studies the side effects and how well removing the planning tumor volume (PTV) from radiation therapy (RT) works in treating patients with head and neck squamous cell carcinoma (HNSCC). Standard therapy for HNSCC often involves giving RT with chemotherapy; however, this approach is associated with a high level of short- and long-term side effects. RT uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. RT is planned to be delivered based on three volumes of the tumor. The first is the gross tumor volume which is the area of the tumor that can be seen, felt, or measured on imaging. The second is the clinical tumor volume which includes the gross tumor volume as well as area beyond this to account for disease that cannot be seen on imaging and may have spread. The third is the PTV which includes an area beyond both the gross tumor volume and clinical tumor volume to account for errors that may happen during RT, such as setup error or movement. As the area between the clinical tumor volume and PTV is not cancer and current advances in RT have improved RT accuracy, researchers think that removing PTV from RT may lower side effects while still being an effective treatment. Removing the PTV from RT may safe, tolerable, and/or effective in treating patients with HNSCC.

PRIMARY OBJECTIVES:
I. Describe the effect of eliminating PTV on locoregional control and marginal recurrence at 6 months in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
II. Describe the effect of PTV on early toxicity, PRO (patient reported outcomes) and QOL (quality of life) in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
SECONDARY OBJECTIVES:
I. Describe the effect of eliminating PTV on locoregional control at 2 and 5 years in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
II. Describe the patterns of failure when eliminating PTV at 3 months, 2 years and 5 years in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
III. Describe the effect of eliminating PTV on later toxicity in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
IV. Describe the effect of eliminating PTV on later PRO (patient reported outcomes) and QOL (quality of life) in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
V. Describe differences in dosimetric comparison plans with and without PTV in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
VI. Describe the effect of eliminating PTV on marginal recurrence rate at 2 and 5 years in patients with HNSCC undergoing definitive RT, with or without chemotherapy.
OUTLINE:
Patients undergo intensity-modulated radiation therapy (IMRT) or image-guided radiation therapy (IGRT) without PTV 5-6 times a week for thirty-five treatment fractions over 6-7 weeks in the absence of disease progression or unacceptable toxicity. Patients may also receive concurrent chemotherapy on study. Additionally, patients undergo computed tomography (CT), fludeoxyglucose F-18 (FDG)-positron emission tomography (PET)/CT, and laryngopharyngoscopy during screening and CT or FDG-PET/CT during follow up.
After completion of study treatment, patients are followed up every 3 months during years 1-2 and then every 6 months during years 3-5.

Women of childbearing potential (WOCBP): negative urine or serum pregnancy test. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
-
Agreement by females and males of childbearing potential to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 6 months after the last dose of protocol therapy
- Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for > 1 year (women only)

-
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. In other words, to participate in this protocol, the patient must have clinically or radiographically evident gross disease for which disease response can be assessed. Patients with unknown primary or resected primary are eligible if gross nodal disease is present
-
Patients with simultaneous primary cancers or separate bilateral primary tumor sites are excluded with the exception of patients with bilateral tonsil cancers
-
Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields

-
Acquired immune deficiency syndrome (AIDS) based upon current Centers for Disease Control and Prevention (CDC) definition with immune compromise. Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible. 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 immuno-compromised patients

Patients who are immune to hepatitis B (anti-Hepatitis B surface antibody positive) are eligible (e.g. patients immunized against hepatitis B)
-
Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment for the hepatitis, they are eligible if they have an undetectable HCV viral load. Hepatitis C testing is not required for entry into this protocol
- Note: Known positive test for hepatitis C virus ribonucleic acid (HCV RNA) indicating acute or chronic infection would make the patient ineligible unless the viral load becomes undetectable on suppressive therapy
-
-
Clinically significant uncontrolled illness
-
Females only: Pregnant or breastfeeding
-
Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns with clinical study procedures

Percent of patients experiencing locoregional recurrence and marginal recurrence
Časové okno: At 6 months post-radiation therapy
|
Will be summarized using descriptive statistics. Will be calculated using the number of patients local or regional recurrence and marginal recurrence divided by the total number of treated/evaluable subjects. Point estimates and two-sided 95% exact binomial confidence intervals will be reported. As secondary analyses, time to locoregional recurrence will be measured from completion of radiation therapy to the first documented local or regional recurrence. The cumulative incidence of locoregional recurrence at 3 months, 2 years, and 5 years will be estimated. Patients alive and free of locoregional recurrence will be censored at the date of their last contact. Point estimates and two-sided 95% confidence intervals will be reported. |
