6. All men, as well as women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 30 days following completion of therapy.

2. Planned neoadjuvant therapy for the current NSCLC.
3. History of major allergic reactions attributed to adhesive or compounds in TTFields micro-array.
4. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that, in the opinion of the investigator, would limit compliance with study requirements.
5. Pregnant or nursing patients due to the potential for congenital abnormalities and the potential of this regimen to harm nursing infants.
