*Compared to the baseline.
†High or low is defined as more or less than 60 pg/ml in sera.
‡4wks after last injection.
§From the registration (days).
¶Withdrawn from the study by sudden hypertensive cerebral hemorrhage.
||A censored case due to the termination of the study.
#After surgical removal of target lesion (LN metastasis), no recurrence was observed.
**Though target lesion became smaller, accumulation of pleural effusion was increased.
