Summary
Sixty-one patients with locally advanced squamous cell carcinomas of oral cavity and oropharynx were treated with chemotherapy, intravenously applied, in addition to radiation and/or surgery. An attempt was made to synchronize the tumor cell population by application of low doses of Vinblastine and the subsequent chemotherapy was based on the uptake of 99m-Tc — labelled Bleomycin in the tumor as an indication of synchronization. Increased number of mitoses in aspiration biopsy specimens and shift in the DNA distribution pattern on DNA histograms were taken as indicative of synchronization. A 50–100% regression of the tumor was achieved in 19 out of 38 patients with residual or recurrent tumors. The results were better in those patients, who received chemotherapy based on individual Tc-Bleomycin uptake curves. In 23 patients with previously untreated T3 tumors of oral cavity and oropharynx the results were somewhat better, but there was no statistically significant improvement on attempts with synchronization in this small series. There were no serious complications connected with chemotherapy.
