Task: Answer Verification
Input (English): Question: Is induction chemoradiation superior to induction chemotherapy alone in stage IIIA lung cancer?
Answer: Published evidence is sparse but does not support the use of radiation therapy in induction regimens for stage IIIA (N2). Given the potential disadvantages of adding radiation preoperatively, clinicians should consider using this treatment strategy only in the context of a clinical trial to allow better assessment of its effectiveness.
Output (English): no
