• \- Surgery (including exploratory/experimental thoracotomy): 4 weeks
• \- Pericardial drainage: 1 week
• \- pleural adhesion not attributed to anti-species positive substances (including biological response regulators such as Picibanil): 2 weeks

• Women in childbearing age should be negative in serum or urine pregnancy tests within 7 days prior to test treatment.
• Male and childbearing female test subjects with female partners' pregnancy must agree to use the following two high-efficiency test methods for at least 180 days after the last dose of the assigned treatment is administered. Bevacizumab can also damage a woman's reproductive ability. Therefore, women who have entered the bevacizumab combination group should be preceded by discussions on preserving the reproductive ability of women who are likely to become pregnant before treatment - asceticism
