Irradiation of Large Lung Tumors or Two or More Lung Metastases Simultaneously

Phase 1
Completed
Conditions
Lung Cancer
Metastatic Lung Cancer
Interventions
Radiation: Stereotactic Body Radiotherapy (SBRT)
Registration Number
NCT01543672
Lead Sponsor
The Netherlands Cancer Institute
Brief Summary

Treatment of larger tumor volumes or ≥ 2 lung metastases simultaneously in lung cancer patient using Stereotactic Body Radiation Therapy (SBRT) in a mean-lung dose escalation study.

Detailed Description

A phase I/II multicenter trial will be conducted in patients with medically inoperable with peripheral non small cell lung cancer (NSCLC) \> 5 cm without lymph node involvement (group A) or medically with ≥ 2 or more lung metastases (group B). Radiation pneumonitis is expected to be dose-limiting in these patients and there is evidence that the incidence is predicted by the mean lung dose (MLD). The MLD escalation will be performed separately in both patient groups, using a time-to-event continual reassessment method (TITE-CRM). All patients will receive 3-5 fractions SBRT to the lung tumor(s), with a minimum mean PTV dose ≥ 42 Gy. Fraction size may be downscaled based on the MLD constraint.

Primary Outcome Measures
NameTimeMethod
MLD4 years

The assessment of the maximum mean lung dose that can be safely treated with SBRT and that is associated with a 20% probability of the DLT.

Secondary Outcome Measures
NameTimeMethod
loco-regional control4 years

Determine the local control and regional control as a function of the mean lung dose, the largest toxicity effects as a function of the MLD and the overall survival.

Quality of life assessment2 years

valuate the increase or decrease of physical discomfort.

overall survival5 years

Determine the local control and regional control as a function of the mean lung dose, the largest toxicity effects as a function of the MLD and the overall survival.
