[Neoadjuvant chemotherapy in head and neck cancer]

BACKGROUND: Neoadjuvant chemotherapy has an increasing role in multimodality treatment of advanced head and neck cancer. In this paper we summarize our first results with this treatment. METHOD: Thirty-five, previously untreated, mostly inoperable head and neck cancer patients were given two cycles of Cisplatin and 5FU chemotherapy. We continued the therapy only in case of regression until four cycles, then the patients received surgical and/or radiotherapy according to their status. After the treatment patients' status was regularly evaluated. RESULTS: We detected 4 complete and 20 partial responses after the chemotherapy. Three patients became eligible for a radical operation. At this moment 10 patients are free of tumor, 8 patients died in consequence of the tumor, we have no data in 3 cases, 3 patients are given palliative therapy because of progression, 4 patients are receiving radiotherapy and 7 patients with partial response are candidates for further active oncotherapy. CONCLUSIONS: Although the number of the patients we treated is too small for a statistical analysis, our results are similar to the conclusion of the large randomized studies: after neoadjuvant chemotherapy of advanced head and neck cancer partial response can improve the result of surgical or radiological treatment. Neoadjuvant chemotherapy does not improve survival in advanced head and neck cancer, but it is of great importance because of better quality of life of patients, especially those who had organ preserving therapy.

[Rabies in Hungary].

The rabies in Hungary between 1954 and 1967 was sporadic, and only later it became an epidemic disease (800-1,300 cases per year). More than 90% of the cases was diagnosed in foxes. Rabies occurs at different frequencies all over the country. Defense has been based on annual vaccination of dogs against rabies and on decrease of the fox populations with hunting, poisoning and gasification of burrows. Nowadays we have considered to initiate oral vaccination of foxes and at the same time to avoid poisoning because of its environmental effects, and gasification because of its low effectiveness.
