About
This randomized phase III trial studies how well gefitinib works in treating patients with stage IB, II, or IIIA non-small cell lung cancer that was completely removed by surgery. Gefitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known if gefitinib may be an effective treatment in preventing tumors from returning after they have been removed by surgery.
Full description
PRIMARY OBJECTIVES:
I. To assess, in comparison with placebo, the impact of adjuvant therapy with two years of daily oral ZD1839 (IRESSA) (gefitinib) on the overall survival of patients with completely resected (T1N1-2, T2N0-2, T3N0-2) non-small cell lung cancer (NSCLC).
SECONDARY OBJECTIVES:
I. To compare the disease-free survival in the placebo arm to the ZD1839 (IRESSA) arm.
II. To confirm the prognostic significance of epidermal growth factor receptor (EGFR) expression, phosphorylation and mutations when present in the primary tumor.
III. To assess the ability of EGFR expression, phosphorylation and mutations in the primary tumor to predict the relative impact of ZD1839 (IRESSA) on survival.
IV. To establish a comprehensive tumour bank linked to a clinical database for the further study of molecular markers in resected NSCLC.
V. To further evaluate toxicity related to ZD1839 (IRESSA).
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive gefitinib orally (PO) once daily (QD) for 2 years in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive placebo PO QD for 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 6 months, every 6 months for 3 years, and then annually thereafter.

Inclusion criteria
-
Patients must have histological proof of a primary non-small cell lung cancer (bronchoalveolar carcinomas presenting as a discrete solitary radiological mass or nodule are eligible)
-
Patients must be classified post-operatively as stage IB, II or IIIA on the basis of pathologic criteria
-
At the time of resection a complete mediastinal lymph node resection or at least lymph node sampling should have been attempted; if a complete mediastinal lymph node resection or lymph node sampling was not undertaken, any mediastinal lymph node which measured 1.5 cm or more on the pre-surgical computed tomography (CT)/magnetic resonance imaging (MRI) scan or any area of increased uptake in the mediastinum on a pre-surgical positron emission tomography (PET) scan must have been biopsied; note: a pre-surgical PET scan is not mandatory
-
The nodal tissue must be labelled according to the recommendations of the American Thoracic Society; surgeons are encouraged to dissect or sample all accessible nodal levels; the desirable levels for biopsy are:
- Right upper lobe: 4, 7, 10

- Left upper lobe: 5, 6, 7, 10
- Left lower lobe: 7, 9, 10
-
-
Surgery may consist of lobectomy, sleeve resection, bilobectomy or pneumonectomy as determined by the attending surgeon based on the intraoperative findings; patients who have had only segmentectomies or wedge resections are not eligible for this study; all gross disease must have been removed at the end of surgery; all surgical margins of resection must be negative for tumor
-
No more than 16 weeks may have elapsed between surgery and randomization; for patients who received post-operative adjuvant platinum-based chemotherapy, no more than 26 weeks may have elapsed between surgery and randomization
-
Patient must consent to provision of and investigator(s) must agree to submit a representative formalin fixed paraffin block of tumor tissue at the request of the Central Tumor Bank in order that the specific EGFR correlative marker assays may be conducted

Absolute granulocyte count >= 1.5 x 10^9/L or >= 1,500/ul
-
Platelets >= 100 x 10^9/L or >= 100,000/ul
-
Total bilirubin within normal institutional limits
-
Alkaline phosphatase =< 2.5 x institutional upper limit of normal; if alkaline phosphatase is greater than the institutional upper limit of normal (UNL) but less than the maximum allowed, an abdominal (including liver) ultrasound, CT or MRI scan and a radionuclide bone scan must be performed prior to randomization to rule out metastatic disease; if the values are greater than the maximum allowed, patients will not be considered eligible regardless of findings on any supplementary imaging
-
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and/or alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal; if AST (SGOT) or ALT (SGPT) are greater than the institutional upper limit of normal (UNL) but less than the maximum allowed, an abdominal (including liver) ultrasound, CT or MRI scan must be performed prior to randomization to rule out metastatic disease; if the values are greater than the maximum allowed, patients will not be considered eligible regardless of findings on any supplementary imaging
-
Patient must have a chest x-ray done within 14 days prior to randomization; patient must have a CT or MRI scan of the chest done within 90 days prior to surgical resection if at least one of the following was undertaken:
- A complete mediastinal lymph node resection; or
- Biopsy of all desired levels of lymph nodes - as specified above; or
- A pre-surgical PET scan within 60 days prior to surgical resection If none of the above was undertaken then the CT or MRI scan of the chest must have been performed within 60 days prior to surgical resection Note: a pre-surgical PET scan is not mandatory
