title: Paclitaxel and carboplatin in neo-adjuvant and concomitant chemoradiotherapy in locally advanced head and neck squamous cell carcinoma.
abstract: OBJECTIVE
  To evaluate feasibility of neoadjuvant chemotherapy (NA-CT) followed by CT + radiotherapy (RT) in locally advanced or unresectable head and neck squamous cell carcinoma (HNSCC).
  
  
  METHODS
  22 HNSCC patients were enrolled (18 males, 4 females; median age, 59.5 years; median ECOG PS, 1). Sites of disease: oral cavity, 18.2%; oropharynx, 40.9%; hypopharynx, 18.2%; larynx, 4.6%, multiple sites, 18.2%. T (tumor) category: T2, 13.6%; T3, 31.8%; T4, 54.5%. N (nodes) category: NO, 9.1%; N1, 18.1%; N2, 40.9%; N3, 31.8%. Stage: III, 4.6%; IVA, 63.6%; IVB, 31.8%. Induction carboplatin (AUC = 6) and paclitaxel (200 mg/m2) x 3 cycles (q21 days) were given. Responders received definitive radiotherapy with concurrent carboplatin (35 mg/m2/day from days 1 to 5 in weeks 1, 3, 5 and 7) and paclitaxel (50 mg/m2 on days 10, 24 and 38). Patients with node involvement were suggested to undergo postradiotherapy neck dissection.
  
  
  RESULTS
  NA-CT. 97% of planned chemotherapy cycles were administered. Prevalent toxicity was hematologic: 50% G4 neutropenia and 31.8% G3, one neutropenic fever. All patients had alopecia. Complete responses in T and N were 4 (18.2%) and 3 (15%), respectively. Partial responses were 13(59%) and 9 (45%). There was 1 progressive disease. CT + RT. 79.9% of planned cycles of CT were administered. In 19 patients (86.4%) more than 50% of planned cycles of CT were completed. Median dose of RT was 70.2 Gy on T/N+ and 54 Gy on NO. Limiting toxicity was mucositis in 77.3%, followed by neutropenia (59.1% G3-G4). Median weight loss was 4.9%.18.2% of patients required hospitalization. Complete responses in T and N were 15 (68.1%) and 8 (40%), respectively. Partial responses were 5 (22.7%) and 7 (35%).
  
  
  CONCLUSIONS
  The preliminary results of this study are encouraging, despite the toxicity. Adequate follow-up is required to evaluate efficacy in terms of local-regional control and overall survival.
