In case this phase II trial has favorable results, a phase II/III trial on maximally tolerable, individualized, hypofractionated radiotherapy within a shorter overall-treatment time is aimed for.', 'detailedDescription': "In the Netherlands, approximately 10.000 new patients are diagnosed with lung cancer every year. Of these, 80% present with non-small-cell lung cancer. Between 1995 and 2008, the national incidence has risen with 16% caused by an impressive increase of 53% in women suffering from this disease. The aggressive nature of this disease leads to a one-year survival rate of 45% and a 5-year survival rate of only 14%.\n\nIt is widely accepted that surgery provides the best chance of cure in patients with operable NSCLC (www.oncoline.nl). In practice, only 20% of patients are amenable for tumor resection with curative intent. Alternatively, stereotactic body radiation therapy (SBRT) results in excellent local control in localized early stage disease.\n\nIn locally advanced, inoperable disease, combined chemotherapy and external-beam radiotherapy (EBRT) are increasingly being used. Evidence suggests that concurrent schedules are more effective than sequential treatments despite increased toxicity, although the true magnitude of the additional benefit remains uncertain. However, a large number of patients with locally advanced NSCLC is not suitable for concurrent chemoradiotherapy due to their general condition, age, comorbidity or tumor-related factors. Therefore, there is a need to increase effectiveness of treatment for all patients with advanced stage NSCLC undergoing either radiotherapy alone, neoadjuvant chemotherapy followed by radiotherapy, or concurrent treatment.\n\nApart from the addition of chemotherapy, treatment modification by intensification of the radiotherapy schedule or by dose escalation has been proven beneficial. Several phase I/II trials explored altered EBRT fractionation schedules that increased the biological effective dose to the primary tumor and reduced local relapse rate. Thereby, two main principles were pursued: reduction of the dose per fraction (≤ 1.8 Gy), giving two or three fractions per day (so-called hyperfractionation), aimed at sparing normal tissues while increasing the dose to the primary tumor; increase of the fraction dose (≥ 2 Gy), combined with a reduction in the total number of fractions (so-called hypofractionation) aimed at increasing the effective tumor dose in less radiation-sensitive primary tumors. On the one hand, hyperfractionation limits the treatment-related side-effects, on the other hypofractionation is attractive for the patient and radiation department as the number of treatment fractions can be reduced.\n\nIntensification of the irradiation schedule by continuous, hyperfractionated radiotherapy (CHART) delivered in 12 consecutive days showed an absolute improvement in two-year survival. With the advent of highly conformal dose planning and delivery techniques during the last decade (i.e., 3-dimensional conformal radiation therapy, 3D-CRT; intensity-modulated radiation therapy, IMRT; volumetric-modulated arc therapy, VMAT/RapidArc; Tomotherapy), organ-sparing technology became widely available. Recently, van Baardwijk and collaborators published an individualized dose prescription study in 166 stage-III NSCLC patients. Already in 2006, Belderbos et al. reported favorable toxicity data and an encouraging failure-free interval in 88 inoperable NSCLC patients treated with intensified, hypofractionated 3D-CRT based on the MTD to the lung.\n\nApart from these reported studies, there are three hypofractionation trials being conducted elsewhere. In the UK, two 3D-CRT based phase I/II trials have been approved investigating individualized dose escalation based on normal tissue dose constraints in patients with stage II or stage III NSCLC (ISRCTN12155469 and I-START; CRUK/10/005). In the US, the University of Wisconsin is conducting a helical tomotherapy-based hypofractionation study (NCT00214123) with pulmonary toxicity (pneumonitis grade 3 lasting for more than 2 weeks) as primary endpoint.\n\nThe reported hypo- and hyperfractionation studies have a 'trial-and-error' approach for dose-level estimation in common. In a recent in silico trial in 26 stage III NSCLC patients, we have investigated the use of a dedicated software tool for individual dose escalation by hypofractionation. Based on an existing, clinical IMRT/VMAT treatment plan (66 Gy in 33 fractions), radiation dose was escalated by scaling the radiation dose until the maximum tolerated dose constraints for the healthy lung, the esophagus, spinal cord, brachial plexus or heart was met. The aim of this present study is to test the feasibility and toxicity of individualized hypofractionated radiotherapy, and to report outcome data. In case this phase II trial has favorable results, a phase II/III trial on maximally tolerable, individualized, hypofractionated radiotherapy within a shorter overall-treatment time is aimed for."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
