Eligibility
Inclusion criteria
Inclusion criteria: Age >= 18 years WHO 0-1 Maximal mouth opening of >= 40 mm for woman and >= 45mm for man, before treatment Squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx and larynx proven by cytology/histology Locally-advanced disease (stage III-IV) Curative intend treatment with radio(chemo)therapy in the primary setting Ability to understand the requirements of the study and to give written informed consent, as determined by the treating physician Written informed consent
Exclusion criteria
Exclusion criteria: Patients previously treated by radiation on the same target volume Any condition or circumstance potentially hampering compliance with the follow-up schedule Patients having pacemakers or clustered metal markers that could interfere with the treatment, based on the treatment planning (from a total length >2 cm of metal objects in direct contact). Tumor location caudal to a tracheostomy (this prevents penetration of the microwaves to the tumor). Anatomical boundaries of the shoulders prohibiting positioning of the applicator.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Safety and tolerability of thermotherapy in combination with standard chemoradiotherapy in LAHNSCC patients. Safety is assessed by the occurrence of dose-limiting toxicities and tolerability is assessed by the ability of patients to complete planned thermotherapy treatments, in order to determine the RP2D. DLTs, along with tolerability criteria, will guide the dose escalation or de-escalation decisions. Dose-limiting toxicity (DLT) of trismus will be objectively assessed by measuring mouth opening using a caliper according to a standardized protocol. Patients will be asked to open their mouths as wide as possible, and the distance between the incisal edges of teeth 11 and 41 (or from the dental prosthesis) will be measured. For edentulous patients without a dental prosthesis, the alveolar ridge of the lower and/or upper jaw (region 11 and 41) will be used. Maximal mouth opening will be measured at baseline, after each thermotherapy fraction, and at regular follow-up visits (end of radiotherapy, 6, 12, and 24 weeks post-radiotherapy). Additionally, DLTs will be closely monitored at the same time points. Tolerability of the thermotherapy dose is defined as the ability of the patient to successfully complete most thermotherapy fractions. When most patients have pain complaints or large discomfort, the thermotherapy dose level is not tolerable to endure and de-escalation will be necessary. The tolerability of a certain thermotherapy dose is determined on 3 different levels: On the level of individual thermotherapy fractions On the level of the individual patient, combining all thermotherapy fractions On the level of the dose level cohort, assessing all patients treated with that certain thermotherapy dose. Level 1 - An individual thermotherapy treatment takes 75 minutes. In case of pain or discomfort during the thermotherapy treatment, optimization of the thermotherapy treatment plan will take place in real-time/online, re | — |
Secondary
| Measure | Time frame |
|---|---|
| Registration of tolerability and DLT in (elderly) LAHNSCC patients receiving thermotherapy in combination with radiotherapy alone. Local control, 3-years Progression Free Survival and 3-years overall survival. System performance: treatment session characteristics, occurrence of technical issues requiring treatment adaptation, reflection measurements. | — |
