The neonatal hepatitis B vaccination (HBVac) was implemented 35 years ago in Taiwan, but many vaccinees exhibit inadequate long-term vaccine-induced seroprotective hepatitis B surface antibody (anti-HBs) levels. We investigated the association of the human leukocyte antigen (HLA) alleles (DPA1, DPB1, DQA1, and DQB1) with the long-term immunological...

Rationale: Patients of NSCLC with mutated EGFR are relatively sensitive to EGFR-TKI treatment and have longer progression-free survival (PFS) when treated with EGFR-TKI, compared with platinum-based chemotherapy. However, many advanced NSCLC patients with mutated EGFR do not response to first-line EGFR-TKI treatment and still have shorter PFS. Ob...

A recent genome-wide association study (GWAS) of subjects from Japan and South Korea reported a novel association between the TP63 locus on chromosome 3q28 and risk of lung adenocarcinoma (p = 7.3 × 10(-12)); however, this association did not achieve genome-wide significance (p ≤ 10(-7)) among never-smoking males or females. To determine if this as...
