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 …

Verschil in radiotherapeutische dosis bij het mammacarcinoom. Het effect van verschillende doelgebieden en planningstechnieken op de dosis in het doelgebied en risico-organen.

Myrthe Maas (Student); Silvia Enders (Begeleider)

In dit onderzoek zijn verschillende (sub)groepen van mammapatiënten geanalyseerd met de daarbij horende mean heart dose (MHD), mean lung dose (MLD) en mean clinical target volume dose (meanCTVdose). Hierbij is gekeken naar het verschil tussen 2013 en 2016 bij verschillende doelgebieden en planningstechnieken …

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. …

Focal therapy bij patiënten met een prostaatcarcinoom

Maggie Klessens (Begeleider); `Jack Venselaar (Begeleider); Loes Spee (Student)

Het is moeilijk om eenduidig vast te stellen welke behandelingsmethode, Intensity Modulated Radiotherapy (IMRT) of High Dose Rate (HDR) brachytherapie, de voorkeur heeft bij focal therapy van patiënten met een prostaatcarcinoom. Het is nog onduidelijk wat de invloed van het prostaatvolume en de locatie …

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 …
