Prevention of Death From Adenocarcinoma of the Lung by Low Dose Aspirin
PRIMARY OBJECTIVES:
I. To determine whether ASA (acetylsalicylic acid) 325 mg inhibits prostaglandin E2 (PGE2)
biosynthesis in patients with early stage non-small cell lung cancer (NSCLC). Cyclooxygenase
(COX) catalytic activity will be determined by measuring the metabolite of PGE2,
11alpha-hydroxy-9,12-dioxo-2,3,4,5-tetranor-prostane-1,20 dioic acid (PGE-M) in urine pre-
and post-ASA 325 mg as a surrogate of systemic PGE2 biosynthesis.
SECONDARY OBJECTIVES:
I. To determine whether COX-2 protein has a slow turnover in adenocarcinoma of the lung. COX
turnover will be determined by measuring urinary PGE-M levels daily for 7 days after
discontinuing ASA 325 mg. COX-2 and Prostaglandin expression will also be measured in tumor
samples of patients taken at the time of surgery.
OUTLINE:
Patients receive acetylsalicylic acid orally (PO) for 7 days and urine is collected for 7
days post therapy.

Inhibition of PGE2 biosynthesis
Pearson chi-square test or Fisher's exact test will be used to assess the categorical variables. Hypotheses will be tested at the level of alpha = 0.05. Point estimates along with the corresponding p-values and 95% confidence intervals will be reported.
