Trial Outcomes & Findings for Prognostic Study of Metastases in Patients With Stage I, Stage II, or Stage III Non-small Cell Lung Cancer That Can Be Removed by Surgery (NCT NCT00003901)

NCT ID: NCT00003901

Last Updated: 2017-02-16

Results Overview

Overall survival was defined as the time period between patient registration and death. All histologically negative lymph nodes (N0) participants were examined for occult metastases (OM), diagnosed by cytokeratin immunohistochemistry (IHC).

Participant Flow

One thousand-three hundred and ten participants were enrolled between July 1999 and March 2004. Data was analyzed in June 2009 when all eligible participants could have been observed for at least 5 years.

Two-hundred and sixty-three participants were ultimately removed from the study for various reasons (e.g. initially ineligible, final histology other than non-small-cell lung cancer), leaving 1047 participants evaluable for study endpoints.

PRIMARY outcome

Timeframe: Up to 5 years

Population: Eligible participants with N0 non-small-cell lung cancer who had underwent pulmonary resection and were examined for OM

Overall survival was defined as the time period between patient registration and death. All histologically negative lymph nodes (N0) participants were examined for occult metastases (OM), diagnosed by cytokeratin immunohistochemistry (IHC).

SECONDARY outcome

Timeframe: Up to 5 years

Population: Eligible participants with N0 non-small-cell lung cancer who had underwent pulmonary resection and were examined for OM

Disease-free survival was defined as the time period from registration to the date of first evidence recurrent disease in patients following curative pulmonary resection or death. All histologically negative lymph nodes (N0) participants were examined for occult metastases (OM), diagnosed by cytokeratin immunohistochemistry (IHC).
