RESUMEN
BACKGROUND AND PURPOSE: Radiotherapy plays a pivotal role in lung cancer treatment. Selection of patients for new (radio)therapeutic options aiming at improving outcomes requires reliable and validated prediction models. We present the implementation of a prospective platform for evaluation and development of lung radiotherapy (proPED-LUNG) as an instrument enabling multidimensional predictive modelling. MATERIALS AND METHODS: ProPED-LUNG was designed to comprise relevant baseline and follow up data of patients receiving pulmonary radiotherapy with curative intent. Patient characteristics, diagnostic and staging information, treatment parameters including full dose-volume-histograms, tumour control, survival, and toxicity are scored. Besides physician-rated data, a range of patient-rated data regarding symptoms and health-related quality-of-life are collected. RESULTS: After 18 months of accrual, 315 patients have been included (accrual rate, 18 per month). Of the first hundred patients included, 70 received conformal (chemo)radiotherapy and 30 underwent stereotactic radiotherapy. Compliance at 3 and 6 months follow-up was 96-100% for patient-rated, and 81-94% for physician-rated assessments. For data collection, 0.4 FTE were allocated in a 183 FTE department (0.2%). CONCLUSIONS: ProPED-LUNG is feasible with high compliance rates and yields a large amount of high quality prospective disease-related, treatment-related, patient- and physician-rated data which can be used to evaluate new developments in pulmonary radiotherapy.

Small-cell lung cancer (SCLC) is characterized by rapid growth and early metastasis. Despite its sensitivity to cytotoxic treatment, until now treatments have failed to control or cure this disease in most patients. Here, we describe a patient with SCLC in which symptoms caused by iris metastasis were the only sign of relapse after multimodality treatment.
