Long-term swallowing, trismus, and speech outcomes after combined chemoradiotherapy and preventive rehabilitation for head and neck cancer; 10-year plus update

Karsten, Rebecca T.; van der Molen, Lisette; Hamming-Vrieze, Olga; van Son, RobJ. J. J. H.; Hilgers, Frans J. M.; van den Brekel, Michiel W. M.; Stuiver, Martijn M (Urban Vitality); Smeele, Ludi E.

BACKGROUND: The objective of this study was to explore the 10-year plus outcomes of Intensity Modulated Radiotherapy with concomitant chemotherapy (CRT) combined with preventive swallowing rehabilitation (CRT+) for head and neck cancer (HNC). METHODS: Subjective and objective swallowing, trismus, and …

Radiation dose to the masseter and medial pterygoid muscle in relation to trismus after chemoradiotherapy for advanced head and neck cancer

Sophie A. Kraaijenga; Olga Hamming-Vrieze; Sonja Verheijen; Emmy Lamers (Lid Lectoraat); Lisette van der Molen; Frans J. Hilgers; Michiel W. van den Brekel; Wilma D. Heemsbergen

Abstract Background: We studied the relationship between trismus (maximum interincisor opening [MIO] ≤35 mm) and the dose to the ipsilateral masseter muscle (iMM) and ipsilateral medial pterygoid muscle (iMPM). Methods: Pretreatment and post-treatment measurement of MIO at 13 weeks revealed 17% of …

Prediction model to predict critical weight loss in patients with head and neck cancer during (chemo)radiotherapy

Langius, Jacqueline A.E.; Twisk, Jos; Kampman, Martine; Doornaert, Patricia; Kramer, Mark H.H.; Weijs, Peter J.M. (Lectoraat Voeding En Beweging); Leemans, C. René

OBJECTIVES: Patients with head and neck cancer (HNC) frequently encounter weight loss with multiple negative outcomes as a consequence. Adequate treatment is best achieved by early identification of patients at risk for critical weight loss. The objective of this study was to detect predictive factors …

Development of an iterative reconstruction method to overcome 2D detector low resolution limitations in MLC leaf position error detection for 3D dose verification in IMRT

Visser, Ruurd; J., Godart; Wauben, D.J.L.; Langendijk, J.; van 't Veld, A.A.; Korevaar, E.W.

The objective of this study was to introduce a new iterative method to reconstruct multi leaf collimator (MLC) positions based on low resolution ionization detector array measurements and to evaluate its error detection performance. The iterative reconstruction method consists of a fluence model, a detector …

Multicriteria optimization enables less experienced planners to efficiently produce high quality treatment plans in head and neck cancer radiotherapy

Kierkels, Roel G J; Visser, Ruurd; Bijl, Hendrik P; Langendijk, Johannes A; van 't Veld, Aart A; Steenbakkers, Roel J H M; Korevaar, Erik W

OBJECTIVES: To demonstrate that novice dosimetry planners efficiently create clinically acceptable IMRT plans for head and neck cancer (HNC) patients using a commercially available multicriteria optimization (MCO) system. METHODS: Twenty HNC patients were enrolled in this in-silico comparative planning …

Evaluation of DVH-based treatment plan verification in addition to gamma passing rates for head and neck IMRT

Visser, Ruurd; Wauben, David J.L.; de Groot, Martijn; Steenbakkers, Roel J.H.M.; Godart, Jeremy; van 't Veld, Aart A.; Langendijk, Johannes A.; Korevaar, Erik W.; Bijl, Hendrik P

Background and purpose: Treatment plan verification of intensity modulated radiotherapy (IMRT) is generally performed with the gamma index (GI) evaluation method, which is difficult to extrapolate to clinical implications. Incorporating Dose Volume Histogram (DVH) information can compensate for this. …

Efficient and reliable 3D dose quality assurance for IMRT by combining independent dose calculations with measurements

Visser, Ruurd; Wauben, D.J.L.; de Groot, Martijn; Godart, Jeremy; Langendijk, Johannes A.; van't Veld, A.A.; Korevaar, Erik W.

PURPOSE: Advanced radiotherapy treatments require appropriate quality assurance (QA) to verify 3D dose distributions. Moreover, increase in patient numbers demand efficient QA-methods. In this study, a time efficient method that combines model-based QA and measurement-based QA was developed; i.e., the …

Sequentially delivered boots plans are superior to simultaneously delivered plans in head and neck cancer when the boost volume is located further away from the parotid glands

Anke van Mourik; Emmy Lamers-Kuijper (Lid Lectoraat); Wilma Heemsbergen; Coen Rasch

Purpose: to find parameters that predict which head and neck patients benefit from a sequentially delivered boost treatment plan compared to a simultaneously deliverd plan, with the aim to spare the salivary glands.
