title: [Principles of the simultaneous radiation and polychemotherapy in advanced head and neck carcinoma].
abstract: Concomitant application of chemotherapeutic agents and radiotherapy increases the tumoricidal effects. In this report the biochemical, cell-kinetic and radiobiological interactions of the simultaneous radio-polychemotherapy are discussed. Systemic chemotherapy consisted of cis-dichlorodiammineplatinum (II) (cis-DDP; 60 mg/sqm), 5-fluorouracil (5-FU; 350 mg/sqm) and folinic acid (FA; 50 mg/sqm) on day 2 and 5-FU 350 mg/sqm/24 hrs and FA 100 mg/sqm/24 hrs on days 2-5. Radiotherapy was applied in 13 fractions of 1.8 Gy delivered twice daily from days 3-11. The regimen was repeated on days 22 and 44, reaching the final dose of 70.2 Gy in 8 weeks. With this protocol, optimal tumor regression was achieved in very advanced squamous cell carcinoma of the head and neck. Survival rate after 2 years was 76.8% with 28/32 complete and 4/32 partial remissions. Using an intensive adjuvant treatment, the overall toxicity was tolerable allowing the application of the full therapeutic dosage in 95% without any interruptions.
