Trial Outcomes & Findings for Study of Hypofractionated Radiotherapy Alone in Locally Advanced Nonsmall Cell Lung Cancer Patients (NCT NCT04398199)

NCT ID: NCT04398199

Last Updated: 2022-10-05

Results Overview

In-field progression is defined as growth of the targeted lesions beyond the treated volume. The treated volume will be defined as the 28.75 Gy isodose line (50% of 57.5 Gy). Pathologic confirmation of tumor progression is preferred, but can be determined radiographically by Multidisciplinary Thoracic Oncology Program consensus if biopsy of the lesion in question is not feasible or safe. Investigators will compare the proportion of the sample with any in-field progression at 2 years to the historical control proportion of 0.5, using a one-sample z-test.

Measure
Hypofractionated Radiation Therapy
Hypofractionated radiation therapy will be delivered to all participants. The radiation will be planned in a special way to give the biggest parts of the tumors that are the most difficult to control a little more radiation every day than the lower risk areas. Hypofractionated Radiation Therapy: The prescribed dose will be 70 Gy in 25 fractions. Participants will radiation therapy once a day for 25 days, Monday through Friday (around 5 weeks). Radiation Boost: Undergo simultaneous integrated boost (SIB) to treat both planned target volumes with daily image guidance. This approach allows daily confirmation of target localization and simultaneous delivery of lower dose per fraction to low risk areas while maintaining a high dose per fraction to the highest risk areas.

PRIMARY outcome

Timeframe: At 2 years

Population: Study was terminated early due to low accruals, outcome measure data not available.

In-field progression is defined as growth of the targeted lesions beyond the treated volume. The treated volume will be defined as the 28.75 Gy isodose line (50% of 57.5 Gy). Pathologic confirmation of tumor progression is preferred, but can be determined radiographically by Multidisciplinary Thoracic Oncology Program consensus if biopsy of the lesion in question is not feasible or safe. Investigators will compare the proportion of the sample with any in-field progression at 2 years to the historical control proportion of 0.5, using a one-sample z-test.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 25 months

Population: Study was terminated early due to low accruals, outcome measure data not available.

Toxicities will be evaluated per Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 constructed with a 95% confidence interval.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: At 1 and 2 years after first post-radiotherapy scan

Population: Study was terminated early due to low accruals, outcome measure data not available.

Participants who have experienced local progression by 13 months (1 year following first post-radiotherapy scan) and by 25 months (2 years following first post-radiotherapy scan), and will also compute the same two proportions considering regional progression, distant progression, and any (of the 3 categories) progression. A 95% confidence intervals around these proportions will be constructed. Participants for whom investigators are unable to determine progression status at 1 and 2 years (e.g., because they do not return for the necessary scans, or because they die without evidence of progression) will be left out of these analyses.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: Up to 2 years

Population: Study was terminated early due to low accruals, outcome measure data not available.

Progression-free survival will be evaluated by considering the time from registration to progression of disease or death; those who do not experience either outcome will be censored at date of last visit. Using the Kaplan-Meier lifetable method, and will estimate median survival and corresponding 95% confidence intervals; investigators will also explore simple Cox proportional hazards models of this survival outcomes, to examine the predictive influence of variables such as age, gender, ECOG performance status, stage at diagnosis, planning target volume (PTV) 7000 volume, and planning target volume (PTV) 5750 volume.

SECONDARY outcome

Timeframe: Up to 2 years

Population: Study was terminated early due to low accruals, outcome measure data not available.

Overall survival will be evaluated by considering the time from registration to death from any cause; those who do not die will be censored at date of last visit. Using the Kaplan-Meier lifetable method, and will estimate median survival and corresponding 95% confidence intervals; investigators will also explore simple Cox proportional hazards models of this survival outcomes, to examine the predictive influence of variables such as age, gender, ECOG performance status, stage at diagnosis, planning target volume (PTV) 7000 volume, and planning target volume (PTV) 5750 volume.
