Isotoxic Intensity Modulated Radiation Therapy in Stage III Non-Small Cell Lung Cancer: A Feasibility Study.

Purpose: Not all patients with stage III non-small cell lung cancer (NSCLC) are suitable for concurrent chemoradiation therapy (CRT). Local failure rate is high for sequential concurrent CRT. As such, there is a rationale for treatment intensification.

Experiences and impact of mistreatment and obstetric violence on women during childbearing: a systematic review protocol.

The aim of this review is to synthesize the best available evidence on the experiences of mistreatment and/or obstetric violence in women. Specifically, the objective is to explore, from a woman's point of view, the impacts and consequences of mistreatment and/or obstetric violence during childbearing. The review question is: "What are the experiences and impact of mistreatment and obstetric violence on women during the active period of childbearing?"

Protocol for the isotoxic intensity modulated radiotherapy (IMRT) in stage III non-small cell lung cancer (NSCLC): a feasibility study.

Introduction: The majority of stage III patients with non-small cell lung cancer (NSCLC) are unsuitable for concurrent chemoradiotherapy, the non-surgical gold standard of care. As the alternative treatment options of sequential chemoradiotherapy and radiotherapy alone are associated with high local failure rates, various intensification strategies have been employed. There is evidence to suggest that altered fractionation using hyperfractionation, acceleration, dose escalation, and individualisation may be of benefit.

Predicting Radiation Esophagitis Using 18F-FDG PET During Chemoradiotherapy for Locally Advanced Non-Small Cell Lung Cancer.

Introduction: Treatment of locally advanced non-small cell lung cancer with chemoradiotherapy (CRT) is limited by development of toxicity in normal tissue, including radiation esophagitis (RE). Increasingly, (18)F-fluorodeoxyglucose (FDG) positron emission tomography (PET) is being used for adaptive planning. Our aim was to assess changes in esophageal FDG uptake during CRT and relate the changes to the onset and severity of RE.

Investigation of a Patient Reported Outcome tool to assess radiotherapy-related toxicity prospectively in patients with lung cancer.

Background And Purpose: There is a paucity of data regarding the feasibility and relevance of Patient Reported Outcome (PRO) tools to assess radiotherapy-related toxicity in lung cancer.

Material And Methods: From January to June 2013, lung cancer patients undergoing thoracic radiotherapy/chemo-radiotherapy completed nine patient-adapted Common Terminology Criteria for Adverse Events (CTCAE), the European Organisation for Research and Treatment of Cancer Quality of Life (QoL) questionnaire and the Hospital Anxiety and Depression Scale (HADS) at baseline, the end of radiotherapy and at follow-up. Clinicians completed the same CTCAE items and agreement between patients' and clinicians' reporting was assessed using weighted kappa coefficients.

How can we optimise concurrent chemoradiotherapy for inoperable stage III non-small cell lung cancer?

Latest evidence sets a clear mandate for concurrent chemoradiotherapy as the current standard of care for inoperable stage III non small cell lung cancer patients with good performance status and minimal co-morbidities. However, a survival plateau has been reached, with disappointing results from dose escalation studies using conventional fractionation and studies investigating the addition of systemic doses of chemotherapy delivered before or after concurrent chemoradiotherapy. A review was carried out to address three questions considered fundamental to improving outcome in patients with stage III non-small cell lung cancer: (1) Can radiotherapy regimens be optimised using advanced radiotherapy techniques to improve local control rate and overall survival? (2) Can systemic therapy regimens be optimised to reduce the risk of distant metastases? (3) Should concurrent chemoradiotherapy be considered standard of care for locally advanced non-small cell lung cancer in the elderly? It is clear that further improvement in outcome for these patients will be determined by better local control and by reducing the risk of distant recurrence.

New radiotherapy approaches in locally advanced non-small cell lung cancer.

Radiotherapy plays a major role in the treatment of patients with locally advanced non-small cell lung cancer (NSCLC), particularly since most patients are not suitable for surgery due to the extent of their disease, advanced age and multiple co-morbidities. Despite advances in local and systemic therapies local control and survival remain poor and there is a sense that a therapeutic plateau has been reached with conventional approaches. Strategies for the intensification of radiotherapy such as dose escalation have shown encouraging results in phase I-II trials, but the outcome of the phase III Radiation Therapy Oncology Group 0617 trial was surprisingly disappointing.
