BACKGROUND We conducted a randomized trial of prophylactic cranial irradiation in patients with extensive small-cell lung cancer who had had a response to chemotherapy. METHODS Patients between the ages of 18 and 75 years with extensive small-cell lung cancer were randomly assigned to undergo prophylactic cranial irradiation (irradiation group) or receive(More)
PURPOSE High local control rates can be achieved using stereotactic radiotherapy in Stage I non-small-cell lung cancer (NSCLC), but reports have suggested that toxicity may be of concern. We evaluated early clinical outcomes of "risk-adapted" fractionation schemes in patients treated in a single institution. METHODS AND MATERIALS Of 206 patients with(More)
BACKGROUND The standard of care for operable, stage I, non-small-cell lung cancer (NSCLC) is lobectomy with mediastinal lymph node dissection or sampling. Stereotactic ablative radiotherapy (SABR) for inoperable stage I NSCLC has shown promising results, but two independent, randomised, phase 3 trials of SABR in patients with operable stage I NSCLC (STARS(More)
BACKGROUND Most patients with extensive stage small-cell lung cancer (ES-SCLC) who undergo chemotherapy, and prophylactic cranial irradiation, have persistent intrathoracic disease. We assessed thoracic radiotherapy for treatment of this patient group. METHODS We did this phase 3 randomised controlled trial at 42 hospitals: 16 in Netherlands, 22 in the(More)
BACKGROUND AND PURPOSE Central lung SABR is less established due to toxicity concerns. We describe plan quality and clinical outcomes for patients treated with VMAT SABR using 8×7.5Gy. MATERIALS AND METHODS We studied 80 consecutive patients with primary NSCLC and PTV ⩽2cm from the proximal bronchial tree (PBT), treated between 2008 and 2013. Dosimetric(More)
PURPOSE To investigate the radiosensitizing potential of temozolomide (TMZ) for human glioblastoma multiforme (GBM) cell lines using single-dose and fractionated gamma-irradiation. METHODS AND MATERIALS Three genetically characterized human GBM cell lines (AMC-3046, VU-109, and VU-122) were exposed to various single (0-6 Gy) and daily fractionated doses(More)
BACKGROUND AND PURPOSE The outcome of radiosurgery for vestibular schwannoma (VS) is assessed by posttreatment measurement of tumor size and could be influenced by the timing and quality of the assessment. This study evaluates the volumetric changes of VS after radiosurgery and proposes a radiologic follow-up program. MATERIALS AND METHODS Of 142 patients(More)
PURPOSE To investigate the impact of treatment-related toxicity on health-related quality of life (HRQoL) among patients with head and neck squamous cell carcinoma treated with radiotherapy either alone or in combination with chemotherapy or surgery. PATIENTS AND METHODS The study sample was composed of 425 disease-free patients. Toxicity was scored(More)
BACKGROUND Because survival benefits of treatment with radiotherapy are questionable and such treatment can cause substantial damage to the brain over time, the optimum management strategy for low-grade gliomas remains controversial. We aimed to identify the specific effects of radiotherapy on objective and self-reported cognitive function, and on cognitive(More)
INTRODUCTION Recently, we found that swallowing dysfunction after curative (chemo) radiation (CH) RT has a strong negative impact on health-related quality of life (HRQoL), even more than xerostomia. The purpose of this study was to design a predictive model for swallowing dysfunction after curative radiotherapy or chemoradiation. MATERIALS AND METHODS A(More)
