Materials and methods: Retrospective review of medical records at Seoul National University Hospital between 1998 and 2007 was carried out. Immunohistochemical stain of TUBB3, p53, and ERCC1 was done in paraffin-embedded tumor tissue. We assessed response to treatment, progression-free survival (PFS), overall survival (OS), and cancer-specific survival (CSS). Results: Eighty-five patients with oropharyngeal, hypopharyngeal, and laryngeal cancers received induction chemotherapy with 5-fluorouracil (5-FU) and cisplatin (n = 55), or 5-FU, cisplatin, and docetaxel (Taxotere) (n = 30). Eighty-three received definitive treatment after induction chemotherapy, where 62 received radiotherapy and 21 received surgery. TUBB3-positive patients showed lower response rate than TUBB3-negative patients (69% versus 88%, P = 0.039). Shorter median PFS was observed in TUBB3-positive group (12 versus 47 months, P = 0.001). Shorter median OS was observed in TUBB-positive group not reaching statistical significance (30 versus 59 months, P = 0.072). TUBB3 status significantly influenced CSS (35 months versus not reached, P = 0.017). Positive p53 status was related to poorer OS and CSS. ERCC1 showed no influence on chemotherapy response, PFS, OS, and CSS. Conclusion: TUBB3 is a predictive and prognostic marker along with well-known p53 in HNSCC patients receiving cisplatin-based induction chemotherapy. Clinical impact of ERCC1 is not evident in this setting.
