[Mammary carcinoma in Switzerland (author's transl)].

Combined surgical, radiotherapeutic, and sometimes chemotherapeutic treatment of early stages of operable mammary cancer results in 5-year survival without recurrence in a similar percentage of cases as modified radical mastectomy does. This is demonstrated with 1296 patients of two French and one American groups using comparable indication and therapeutic principles. No controlled studies of long-term results using these principles are thus far available. Preliminary results of a Swiss adjuvant polychemotherapy study after mastectomy show a significant favorable effect only in patients with negative axillary lymph nodes.
