This pilot clinical trial studies low-dose acetylsalicylic acid in treating patients with stage I-III non-small cell lung cancer. Studying samples of urine and blood from patients with cancer in the laboratory may help doctors learn more about changes in biomarkers that occur during treatment with acetylsalicylic acid

Primary Outcome Measures:
  • Change in PGE2 biosynthesis from baseline and at 14 days after discontinuation of a 7-day course of 325 mg ASA per day [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    PGE2 is a product of the COX-2 protein. Measurement of its urinary metabolite PGE-M would indicate the level of systemic biosynthesis of PGE2 and thus inhibition of COX-2 product formation.

Secondary Outcome Measures:
  • Change in PGE-M levels from baseline and daily for 7 days after discontinuation of a 7-day course of 325 mg ASA per day [ Time Frame: 14 days ] [ Designated as safety issue: No ]
    PGE-M is a metabolite of PGE2 in urine. PGE2 is a product of the COX-2 protein. Evidence suggests that COX-2 and PGE2 participate in tumor growth, apoptosis and metastasis, angiogenesis and abrogation of the tumor response. ASA inhibits COX-2. A slow rate of recovery in urinary levels of urinary PGE-M would indicate the rate of catalytically active COX-2 after discontinuation of ASA and may explain the efficacy of once daily low-dose ASA.

Detailed Description:


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.


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.


Patients receive acetylsalicylic acid orally (PO) for 7 days and urine is collected for 7 days post therapy.
