2nd Annual PhD student meeting of the Cancer Research Center Groningen

Schaake, Wouter

Quality of life among prostate cancer survivors:a longitudinal population based study. Purpose To investigate the course of quality of life (QoL) among prostate cancer patients treated with external beam radiotherapy and to compare the results with QoL of a normal age-matched reference population. Patients …

Interfractional deformation of the esophagus in radiotherapy treatment of esophageal cancer

Nick van Rijn (Student); Esther Bloemen-van Gurp

The purpose of this study was to investigate the inter-fractional deformation of the esophagus during radiotherapy treatment of esophageal cancer, using three-dimensional (3D) kilovolt (kV) conebeam computed tomography (CBCT). Additionally, deformation of the aorta and distance between aorta and esophagus …

Impact of tumour invasion on seminal vesicles mobility in radiotherapy of prostate cancer

Floris J. Pos; Robin Kalisvaart; Uulke van der Heide; Jeroen de Vries; Peter Remeijer; Wilma D. Heemsbergen; M. van der Burgt; Jelle Scheurleer (Lid Lectoraat); Laura Bergsma

Abstract gepubliseerd in Elsevier: For patients with intermediate- and high risk prostate cancer, treated with high dose radiotherapy, the CTV generally involves the prostate and (part of) the seminal vesicles (SV) [1,2]. Fiducial markers locate the prostate reliably during radiotherapy [3]. However …

Geometric changes of parotid glands caused by hydration during chemoradiotherapy

Wilma D. Heemsbergen; Petronella M. Kager; Sanne C. C. van Weerdenburg; Peter Remeijer; Emmy Lamers (Lid Lectoraat); Simon R. van Kranen,; Suzanne van Beek,; O. Hamming-Vrieze

Abstract: Plan adaptation during the course of (chemo)radiotherapy of H&N cancer requires repeat CT scanning to capture anatomy changes such as parotid gland shrinkage. Hydration, applied to prevent nephrotoxicity from cisplatin, could temporarily alter the hydrogen balance and hence the captured anatomy. …

An efficient and independent 3D dose calculationtool for quality assurance of complex radiotherapy treatment plans

Visser, Ruurd; Wauben, D.J.L.; Godart, Jeremy; van 't Veld, Aart A.; Korevaar, Erik.W.

To validate the model-based 3D dose calculation performed by the COMPASS system, and to evaluate the use of the combination of model-based and measurement-based 3D dose determination for clinical QA purposes.

Quality of life among prostate cancer patients: a prospective longitudinal population-based study

Schaake, Wouter; de Groot, Martijn; Krijnen, Wim; Langendijk, Johannes A.; van den Bergh, Alfons C.M.

Purpose To investigate the course of quality of life (QoL) among prostate cancer patients treated with external beam radiotherapy and to compare the results with QoL of a normal age-matched reference population. Conclusion Prostate cancer patients experience a small worsening of QoL as compared with …

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 …

Multivariable normal tissue complication probability model-based treatment plan optimization for grade 2-4 dysphagia and tube feeding dependence in head and neck radiotherapy

Kierkels, Roel G J; Wopken, Kim; Visser, Ruurd; Korevaar, Erik W; van der Schaaf, Arjen; Bijl, Hendrik P; Langendijk, Johannes A

BACKGROUND AND PURPOSE: Radiotherapy of the head and neck is challenged by the relatively large number of organs-at-risk close to the tumor. Biologically-oriented objective functions (OF) could optimally distribute the dose among the organs-at-risk. We aimed to explore OFs based on multivariable normal …

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 …
