[Differential diagnosis and treatment of metatypic cancer].

Fifty one patients with metatypic carcinoma (MC), 10 with basalioma, and 10 with squamous cell carcinoma were clinically and immuno-morphologically studied. There were great differences in the localization of basal cell antigen in the epidermis during MC, basalioma, squamous carcinoma of the skin. Expression of fixed immunoglobulins A, M, G in tumor tissues revealed no significant differences. Fifty one patients underwent a complex treatment with prospidin in a total dose of 3,000-3,500 mg (in a daily dose of 100 mg) followed by near-focus X-ray therapy in a total dose of 3,000 Gy (a single dose being 500 Gy). Good immediate and late (the duration of the follow-up was as long as 5 years) results were obtained.
