Sammanfattning

Background In non-small cell lung cancer (NSCLC) stage III, data on patient reported health-related quality of life (HRQL) are scarce, especially regarding concurrent chemoradiotherapy. Aims To evaluate HRQL in patients treated with high dose radiotherapy combined with concurrent chemotherapy or the antibody cetuximab. Methods The study population comprised all patients enroled in either of two phase II trials in locally advanced NSCLC performed in Sweden 2002–2007. The RAKET trial investigated three different ways of increasing local control (accelerated hyperfractionated treatment or concurrent daily or weekly chemotherapy). The Satellite trial evaluated the addition of cetuximab to thoracic irradiation. HRQL was measured at four time points: At baseline, before radiotherapy, 4–6 weeks after radiotherapy and at 3 months follow-up, using the EORTC QLQ-C30 and LC14 set of questionnaires. Results 154/220 patients (65%) who completed HRQL assessments at all time points were included in the longitudinal study. There was a significant decline over time regarding most functioning measures. Dyspnoea and fatigue gradually deteriorated without recovery after completed treatment. Chemotherapy related symptoms showed a transient deterioration, whereas radiotherapy related esophagitis had not fully recovered at 3 months. Patients with stage IIIA disease tended to recover better regarding global QL, fatigue and dyspnoea compared to patients with stage IIIB. Patients with WHO performance status (PS) 0 reported improved global QL and less fatigue over time compared with PS 1. Concurrent chemotherapy was associated with more pronounced fatigue and dysphagia, and worse global QL compared with concurrent cetuximab. Baseline physical functioning was an independent predictor of overall survival. Conclusion Patients undergoing high dose thoracic radiotherapy combined with chemotherapy or cetuximab reported a gradual deterioration in functioning, dyspnoea and fatigue, while treatment related side effects were transient. Radiotherapy with concurrent cetuximab had less negative impact on HRQL than concurrent chemoradiation.
