Summary
The investigators' experimental study found that gossypol was the natural inhibitor of apyrimidinic endonuclease 1 (APE1) and clinical study observed that high expression of APE1 was relative to the platinum-resistance in non-small cell lung cancer. Thus the purpose of this study is to find out whether gossypol can improve the sensitivity of cisplatin-based chemotherapy in the non-small cell lung cancer with apurinic apyrimidinic endonuclease 1 (APE1) high expression

- At least one unidimensional measurable lesion meeting Response Evaluation Criteria in Solid Tumors (RECIST. 2000).

- Patients can have the brain / meningeal metastasis history, but the metastasis must be treated by operation or radiotherapy), and clinically stable for at least 2 months.
