Cryosurgery in the treatment of head and neck neoplasia

Abstract

The clinical and cellular changes which occur after cryosurgery are described. Its advantages as a form of therapy in the treatment of neoplasia are discussed, particularly with regard to pain relief in palliation. However, the limitations of the effectiveness of cryosurgery in cancer therapy are emphasized. The results of cryosurgery are presented in 30 cases of recurrent or persistent neoplasia, which followed more formal treatment. In 5 cases healing appeared to be complete; good palliation was achieved in 6 cases, and useful palliation in 13 cases. There was no response in 6 cases.
