• Negative serum pregnancy test for women of child-bearing potential (performed within 14 days, +/- 1 day, prior to start of treatment); women of child-bearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in the study, she should inform her treating physician(s) immediately
• Ability to understand and the willingness to sign a written Informed Consent Document (ICD); in the event that non-English speaking participants are eligible for this study, a short form (if applicable) or an ICD in their language, will be utilized and completed in accordance with the MD Anderson's "Policy For Consenting Non-English Speaking Participants"

Exclusion Criteria:

• Patients who have previous radiotherapy to the proposed site of skin cancer
• Patients with active cancers other than skin
• Patients currently receiving any other investigational agents at time of study enrollment; patients may have received investigational agents in the past; no washout time period is required
• Patients with a history of brain metastases must be excluded from this clinical study because of their poor prognosis and because they often develop progressive neurological dysfunction that would confound the evaluation of neurological and other adverse events
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to ZD1839
• Age less than 18 years
• Presence of uncontrolled intercurrent illness (co-morbid conditions) that would limit compliance with study requirements including , but not limited to, ongoing or active infection requiring parenteral antibiotics at time of study registration, symptomatic congestive heart failure (NYHA class II or greater), unstable angina pectoris or cardiac arrhythmia requiring maintenance medication
• Pregnant women are excluded from this study because ZD1839 is a signal transduction inhibitor agent with the potential for teratogenic or abortifacient effects; there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with ZD1839, breastfeeding should be discontinued if the mother is treated with ZD1839
• Patients with known immune deficiency are at an increased risk when treated with marrow-suppressive therapy, HIV-positive patients receiving combination anti-retroviral therapy are excluded due to the possible pharmacokinetic interactions with ZD1839; appropriate studies will be undertaken in patients receiving combination anti-retroviral therapy when indicated
• CYP3A4 inducing agents; patients receiving the following CYP3A4 inducing agents will be excluded; these include: carbamazepine, ethosuximide, griseofulvin, modafinil, nafcillin, oxcarbazepine, Phenobarbital, phenylbutazone, phenytoin, rifampin, rifabutin, St. John's Wort, and sulfinpyrazone
• Patients with distant metastatic disease as determined by diagnostic imaging (i.e., chest x-rays) and/or hematologic assessments (i.e., liver enzymes)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Early Progression Rate	Number of participants out of total participants with progression following two 30 day courses of Gefitinib. Tumor response evaluated by Response Evaluation Criteria in Solid Tumors by physical exam, computed tomography (CT) or Magnetic Resonance Imaging (MRI). Progressive disease defined as determined as response to Gefitinib induction therapy: Progression: 25% increase in sum of products of all measurable lesions over smallest sum observed (over baseline if no decrease) using the same techniques, OR clear worsening of any evaluable disease, OR appearance of any new lesion/site, OR failure to return for evaluation due to death or deteriorating condition (unless clearly unrelated to this cancer). Participants restaged on days 15 and 60 of treatment.	Baseline to 60 days, up to 2 courses of induction therapy
Number of Participants With Response Rate During Induction, Dose Escalation, and Concomitant With Radiation.	Completion Induction phase, participants are evaluated for clinical response and resectability. Resectable participants who had achieved at least stable disease and received surgery followed by radiation. Unresectable participants who had achieved at least stable disease received concomitant radiation/Gefitinib.	Up to 100 days
Toxicity as Assessed by the National Cancer Institute (NCI) Common Toxicity Criteria Associated With Gefitinib Therapy: Expected Toxicities (Grade 1 - 3)	Severity and timing of toxicities evaluated according to NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 3. Occurrences of late (post-radiation) toxicities that are radiation-related monitored and included.	Up to 5 years
Toxicity as Assessed by the National Cancer Institute (NCI) Common Toxicity Criteria Associated With Gefitinib Therapy: UnExpected Toxicities (Grade 1 - 3)	Severity and timing of toxicities evaluated according to NCI Common Terminology Criteria for Adverse Events (CTCAE), Version 3. Occurrences of late (post-radiation) toxicities that are radiation-related monitored and included.	Up to 5 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical Response According to Response Evaluation Criteria In Solid Tumors (RECIST)	Number participants with response defined by RECIST: Complete Response (CR): Disappearance all disease; No new lesions/non-evaluable disease; Responders on none/only maintenance doses of corticosteroids. Partial Response (PR): >/= 50% decrease under baseline in sum products perpendicular diameters of measurable lesions; No progression evaluable disease/new lesions; Responders on same/decreasing doses dexamethasone & stable/improved neurological exams. Stable/No Response (SD): Not qualify for CR, PR, or progression; requires minimum 12 weeks duration; Responders on same/decreasing doses dexamethasone & stable/improved neurological exams. Progression (PD): 25% increase in sum of products of all measurable lesions over smallest sum observed (over baseline if no decrease), OR clear worsening any evaluable disease, OR appearance any new lesion/site, OR failure to return due to death/deteriorating condition. All measurable/evaluable sites assessed using same baseline techniques.	Up to 5 years
Frequency and Timing of Local and Distant Failures		From study entry to first documented local recurrence or last patient contact, assessed up to 5 years

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Epidermal Growth Factor Receptor (EGFR) and Phospho-Akt Expression	Samples were not available from all participants because the protocol specified that consenting to tissue biopsies was optional. In addition, some participants presented with regional recurrences, which were not superficially accessible. The sample size was too small to determine the EGFR-proliferative responses activated by the AKT pathway; hence, the monitoring of the status of activated phospho-AKT as an independent marker of EGFR activation could not be performed.	Baseline
