Type of intervention
Medicine Vaccine
Interventions/Control_1 arm1:
The right peptides (up to 4 peptides) for vaccination to individual patients will be selected in consideration of the pre-existing host immunity assessed by the titers of anti-peptide IgG before vaccination, and subcutaneously injected with incomplete Freund's adjuvant every week (3.0 mg/each peptide; 6 times/cycle).
Dai-kenchu-to(5 g/time, 3 times/day) will be orally administered from the date of the first vaccination to the date of the sixth vaccination.

If the patients want to continue the vaccination after completion of the first cycle of 6 vaccinations, the peptide vaccination will be allowed to continue (every 2-4 weeks).
Interventions/Control_2 arm2:
The right peptides (up to 4 peptides) for vaccination to individual patients will be selected in consideration of the pre-existing host immunity assessed by the titers of anti-peptide IgG before vaccination, and subcutaneously injected with incomplete Freund's adjuvant every week (3.0 mg/each peptide; 6 times/cycle).

If the patients want to continue the vaccination after completion of the first cycle of 6 vaccinations, the peptide vaccination will be allowed to continue (every 2-4 weeks).
