Abstract

To report on the incidence of vertebral fractures in patients treated with Intensity Modulated Radiotherapy (IMRT) for locally advanced non-small cell lung carcinoma (NSCLC) and to analyse the association with clinical and dosimetric parameters. Between 2007 and 2012, 524 patients treated with ⩾51 Gy were retrospectively analysed for the incidence of vertebral fractures (VF). Clinical parameters were assessed. In addition, a case control study in 50 patients was performed to study the association between the radiotherapy dose and fractured vertebrae. Three hundred and thirty-six patients were eligible for analyses. Twenty-eight patients (8%) were observed with VF at a median follow up of 12 months. Age was significantly higher in the group with VF (p<0.01). After balancing age, the mean vertebrae dose was most significantly associated with fractures of the vertebrae (p<0.01). VF was observed in 8% of the patients with locally advanced NSCLC. RT dose was associated with the occurrence of thoracic vertebral fractures.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
