Phase I Dose Escalation Trial of Hypofractionated Limited-field External Beam Thoracic Radiotherapy for Limited Stage Small Cell Carcinoma of the Lung
Local control and overall survival rates associated with the standard chemotherapy and
radiotherapy given for limited stage small cell lung cancer are poor and emerging evidence
from several studies suggests that intensifying the radiotherapy dose given may further
improve patient outcomes, but at the cost of increased radiotherapy side effects. This
proposal aims to study a novel method of intensifying chest radiotherapy dose via increasing
the daily radiotherapy dose which is directed at regions of visible disease only. This
strategy allows for delivery of increased radiation doses without prolonging overall
treatment time and allowing potential regrowth of cancer cells. We aim to determine the
maximum radiation dose which can be safely given with chemotherapy for limited stage small
cell lung cancer and study the effects this type of radiation regimen with chemotherapy has
on patient side effects and quality of life. Results from this trial will contribute to the
development of the ideal radiotherapy regimen for limited stage small cell lung cancer. Our
results will add to the literature studying the effects dose-intense radiation strategies
for lung cancer have on patient quality of life.
