MERIT Study – “Multicenter Evaluation of Patient- and Lesion-Specific Prognostic Factors for RadioImmunoTherapy with 90yttrium-Labeled Anti-CD20 in Follicular Non-Hodgkin's lymphoma”.

Abstract Abstract 4792 Background / Aim Although prognostic factors (PF) for conventional lymphoma therapy are well known and used in clinical practice and medical research, the PF for radioimmunotherapy (RIT) have not been fully defined until now. The aim of this prospective multicenter trial is to identify patient- and lesion-specific PF for a standard RIT using 90Yttrium-labeled anti-CD20-antibodies in relapsed or refractory follicular lymphoma (FL) by means of clinical and image data including FDG-PET and CT. To prove the feasibility of the multicenter web-based data collection and to assess the imaging data we performed an analysis on retrospective data. Material and methods This retro…

Early Impact of Pulmonary Fractionated Stereotactic Body Radiotherapy on Quality of Life:Benefit for Patients With Low Initial Scores (STRIPE Trial)

Abstract Introduction Quality of life (QoL) of comorbid patients with pulmonary malignancies is a key issue in considering fractionated stereotactic body radiotherapy (SBRT) indication. This study investigates the early impact of SBRT on QoL. Methods One hundred patients with pulmonary lesions were treated with SBRT from February 2011 to December 2014 within the prospective, monocenter, phase II STRIPE trial. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core module (EORTC QLQ-C30) and the QLQ-LC13 lung cancer-specific questionnaire were used to evaluate QoL before, 2 and 7 weeks after SBRT, then every 3 months for 2 years. We report on the ana…

Quality of Life in NSCLC Survivors - A Multicenter Cross-Sectional Study.

The objective was to assess quality of life (QoL) in lung cancer survivors, compare it to the general population, and identify factors associated with global QoL, physical functioning, emotional functioning, fatigue, pain, and dyspnea.Data from NSCLC patients who had survived 1 year or longer after diagnosis were collected cross-sectionally in a multicenter study. QoL was assessed with the European Organisation for the Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 and the lung cancer module QLQ-LC13 across different clinical subgroups and compared to age- and sex-standardized general population reference values. Multivariable linear regression analyses wer…

The Impact of Radiotherapy Protocol Adherence on the Treatment Outcome in Patients With Locally Advanced NSCLC Treated With Concurrent Chemoradiation: Results From the Radiotherapy Quality Assurance of the International Randomized PET-Plan Trial

PURPOSE/OBJECTIVE(S) The success of intensification and personalization of the curative treatment of non-small cell lung cancer (NSCLC) is strongly associated with the precision in radiotherapy (RT) treatment, which must therefore follow high standards. Herein we evaluate the impact of RT protocol adherence in the prospective international multicenter trial on curative treatment of NSCLC. MATERIALS/METHODS In the open-label, randomized, controlled PET-Plan trial, patients with inoperable NSCLC were randomized at a 1:1 ratio regarding the target volume delineation informed by ¹⁸F-FDG PET and CT plus elective nodal irradiation (Arm A) or target volumes informed by PET alone (Arm B) and receiv…

Chromosomal aberrations in patients with primary biliary cirrhosis.

Chromosomal aberrations in untreated lymphocyte cultures, bleomycin (BLM)-induced aberrations and sister chromatid exchanges (SCE) in the peripheral blood lymphocytes of 11 patients suffering from primary biliary cirrhosis (PBC) and 14 matched control individuals were analysed. The lymphocytes of the PBC patients had on average a lower mitotic index (2.3) compared with controls (3.5) in the untreated cultures. The mean baseline rate of aberrations of the cultured lymphocytes of the patients was 5.3 aberrations per 100 metaphases (%); this was significantly different (P = 0.0291) from that of the controls with a mean of 2.3%. In lymphocytes of the patients and controls, most of the aberratio…

Quality of life after pulmonary stereotactic fractionated radiotherapy (SBRT): Results of the phase II STRIPE trial.

Preserving health related quality of life (HRQOL) plays an important role in considering stereotactic body fractionated radiotherapy (SBRT). The prospective monocenter phase II STRIPE trial investigated long-term HRQOL after SBRT, efficacy and toxicity.Patients with ≤2 pulmonary lesions ≤5 cm were treated with 4DPET/CT-based SBRT (3 × 12.5 Gy or risk-adapted 5 × 7 Gy, to 60% isodose). Follow up (FU) was performed 2 and 7 weeks after SBRT, then 3-monthly for 2 years with assessment of response (primary endpoint: 2-year cumulative incidence of local progression (LP); secondary endpoints: local progression free survival (LPFS), overall survival (OS) and toxicity (CTCAE)). Impact of predefined …

OA12.05 Imaging-Guided Target Volume Reduction in Radiotherapy of Lung Cancer: The Prospective Randomized Multinational PET-Plan Trial

Prophylactic cranial irradiation in stage IV small cell lung cancer

Background: Due to conflicting results between major trials the role of prophylactic cranial irradiation (PCI) in stage IV small cell lung cancer (SCLC) is controversial.Methods: We obtained a list of 13 European experts from both the European Society for Therapeutic Radiation Oncology (ESTRO) and the International Association for the Study of Lung Cancer (IASLC). The strategies in decision making for PCI in stage IV SCLC were collected. Decision trees were created representing these strategies. Analysis of consensus was performed with the objective consensus methodology.Results: The factors associated with the recommendation for the use of PCI included the fitness of the patient, young age…

Psychological distress in lung cancer survivors at least 1 year after diagnosis-Results of a German multicenter cross-sectional study.

Improved inter-observer agreement of an expert review panel in an oncology treatment trial--Insights from a structured interventional process.

Abstract Purpose Oncologic imaging is a key for successful cancer treatment. While the quality assurance (QA) of image acquisition protocols has already been focussed, QA of reading and reporting offers still room for improvement. The latter was addressed in the context of a prospective multicentre trial on fluoro-deoxyglucose (FDG)–positron-emission tomography (PET)/CT-based chemoradiotherapy for locally advanced non-small cell lung cancer (NSCLC). Material and methods An expert panel was prospectively installed performing blinded reviews of mediastinal NSCLC involvement in FDG–PET/CT. Due to a high initial reporting inter-observer disagreement, the independent data monitoring committee (I…
