[Problems of cancer therapy in the hairy part of the head]

Biological assumptions concerning carcinogenesis at the hairy part of the head were discussed. At the Research Institute of Oncology in Sofia, 71 patients suffering from a carcinoma at the hairy part of the head were treated until 1967.--47.2 percent of them were in the first stage, and 34.7 percent in the second stage. The temporal region was affected most (39.3 percent). Contact therapy was done preferably. Three years after treatment, all persons treated (100 percent) were cured--after five years 82.2 percent, and after ten years 58.0 percent. Four patients were affected by regional lymph metastases; in two of these persons, biologically verified metastases of basicellular cancer became evident.
