Primary and Secondary Outcomes:
Objectives:
- To assess the pathologic and radiological response rate after neoadjuvant Gefitinib treatment
- To assess the toxicity of neoadjuvant Gefitinib treatment in clinical stage 1A & 1B NSCLC
- Enrollment
Treatment will be administered on an outpatient basis. Patients may be identified by thoracic surgeons, respirologists and/or interventional chest radiologists for study participation upon clinical and radiographic assessment.
**Diagnostic biopsy, Pretreatment Investigations
If patients have already had a core or FNA biopsy before referral, this material will be sought from the original pathologist for review and inclusion in the study with appropriate consent sought. If a patient does not have a biopsy upon presentation to the thoracic surgeon, and consents to inclusion in the trial, baseline non-invasive assessment will be carried out before a percutaneous biopsy will be mandated as part of entry into the study. After non-invasive staging, patients will be subject to biopsy. In collaboration with pathology, an immediate diagnosis will be made at the time of fine needle aspiration biopsy (or bronchoscopy). After a pathologic diagnosis of cancer is confirmed, subjects will be invited to have additional biopsies will be performed to obtain material for correlative studies, assuming no complications or technical difficulties have arisen. These studies will be done in collaboration with thoracic interventional radiologists from Diagnostic Imaging, who supervises the lung fine needle aspirates and biopsies.
All patients will undergo pre-study assessments for symptoms, performance status, radiographic assessment and blood tests (complete blood count, electrolytes, liver and renal function tests). Assessment of response will occur after the 4-week treatment period. Toxicity will be assessed continuously, with patient assessment weekly on treatment, repeat blood tests at 2 weeks and imaging of measurable disease at 4 weeks. All subjects will be invited to have their initial diagnostic biopsy and subsequent surgical tumor specimen examined as part of the laboratory correlate component of the study. Patients will be considered evaluable for pharmacodynamic assessment if they complete at least 21 of the planned 28 days of therapy.
Once competed, oral Gefitinib will be administered at a dose of 250 mg (1 pill) daily for 28 days prior to the planned mediastinoscopy. Patients may take the pill either with or without food, and are encouraged to take the medication at approximately the same time each day. If the patient forgets to take a dose, they should take the last missed dose as soon as they remember, as long as it is at least 12 hours before the next dose is due. If patient vomits after taking the dose, the dose may be retaken if the tablet is seen in the emesis. The last dose of Gefitinib will be administered not less than 48 hours prior to mediastinoscopy or surgery.
If the mediastinoscopy reveals the presence of Stage III disease, the patient's mediastinoscopy samples may still be analysed as part of the correlative study. Patients will be followed for 90 days or as long as required after the last dose of Gefitinib to ensure resolution of any Gefitinib-related toxicities. However these patients will be offered standard therapy for stage III disease off of study protocol, for example a combination of chemotherapy, radiation plus or minus surgical resection. If these patients do proceed to thoracotomy post-chemotherapy and/or radiotherapy, their resection specimen will not be eligible for this correlative protocol.
**Duration of Therapy and Follow-up
As outlined above, patients will be treated for 28 days before surgery and will also be followed for 90 days post-operatively after thoracotomy to ensure the recovery from surgery. Accrual is estimated at 2 patients per month, for 18 to 24 months, based on accrual rates to other thoracic surgical studies at UHN. Study duration is planned from August 2004 to June 2006.
All patients will be followed in the current standard of care at University Health Network. That is, clinic visits with chest x-ray every 3 months for 2 years, every 6 months in the third year, and annually thereafter. Recorded information will only include vital status and presence or absence of disease recurrence.
