About

The purpose of this study is to determine the timing of influenza vaccination to induce higher antibody response in adult patients with non-hematologic malignancies receiving scheduled cytotoxic chemotherapy.

Full description

The participants will be stratified by the age (cut off; 60 years old) and last year influenza vaccination, and block-randomized to 2 groups; Day 1 vaccination group and Day 11 vaccination group.

Day 1 group will be vaccinated at Day 1, when the cycle of chemotherapy begins. Day 11 group will get the vaccine at Day 11, 10 days after chemotherapy begins.

As the rate of completion of study in the Day 11 group is anticipated lower than Day 1 group, we will assign the participants into Day 1: Day 11 with the different ratio; 4:5.

Hemagglutination inhibition Ab titre at pre-vaccination and post-vaccination (21-28 days after vaccination) will be examined in all participants.

All the participants will be asked if they have any contraindication for influenza vaccine by a physician before vaccination. And they will be monitored for any adverse reaction of the vaccination after 2-4 days(phone calling) and after 21-28 days (visiting the hospital).

Enrollment: 97 patients

Sex: All

Ages: 20+ years old

Volunteers: No Healthy Volunteers

6. Patients who can understand and agreed with the informed consents.

Exclusion criteria

1. Patients who have any contraindication for influenza vaccination.
2. Patients who are supposed to receive the last chemotherapy at the enrollment
3. Patients who receive simultaneous radiation therapy with cytotoxic chemotherapy
4. Patients who receive any immunosuppressant (excluding steroid for anti-emetic effect)
5. Patients with HIV and low CD 4+ T cell count (< 500/uL)
6. Patients with autoimmune disease who are anticipated to have a problem with immunogenicity for vaccine
7. Patients who have transplanted organ and receive immunosuppressants
