Removing the Planning Tumor Volume From Radiation Therapy for the Treatment of Head and Neck Squamous Cell Carcinoma

3. november 2026 oppdatert av: City of Hope Medical Center

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.

Detaljert beskrivelse

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.

    • Assent, when appropriate, will be obtained and documented for adults lacking capacity per institutional guidelines

  • Age: ≥ 18 years

  • Eastern Cooperative Oncology Group (ECOG) ≤ 2

  • Pathologically (histologically or cytologically) proven diagnosis of squamous cell carcinoma (including the histological variants papillary squamous cell carcinoma and basaloid squamous cell carcinoma but not neuroendocrine phenotype) of the oropharynx (tonsil, base of tongue, soft palate, or oropharyngeal walls), larynx and hypopharynx; 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)

  • No metastatic disease and eligible for definitive radiation based on the following diagnostic workup:

    • General history and physical examination within 56 days prior to registration
    • Exam with laryngopharyngoscopy (mirror or in office direct procedure acceptable) within 70 days prior to registration
    • FDG -PET/CT (with or without contrast) within 60 days prior to registration
    • Diagnostic CT scan of neck (with contrast and of diagnostic quality) within 60 days prior to registration

  • Planning to undergo definitive radiation (with or without chemotherapy)

  • 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)

Exclusion Criteria:

  • Recurrent disease

  • T1-T2 glottic cancers

  • Definitive clinical or radiologic evidence of metastatic diseases

  • Cancers considered to be from an oral cavity site (oral tongue, floor mouth, alveolar ridge, buccal or lip), or the nasopharynx, even if p16-positive, or histologies of adenosquamous, verrucous, or spindle cell carcinomas

  • 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

  • Chemotherapy, radiation therapy, biological therapy, immunotherapy within 21 days or five half-lives (whichever is shorter for non-radiation therapy) prior to day 1 of protocol therapy

    • Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects

    • 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

    • For patients with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated. Hepatitis B testing is not required for entry into this protocol

      • Note: Known positive test for hepatitis B virus surface antigen (HBV sAg) indicating acute or chronic infection would make the patient ineligible unless the viral load becomes undetectable on suppressive therapy. 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

  • Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
