title: [Value of cryosurgery in the treatment of malignant nasopharyngeal tumors].
abstract: Sixty-one patients with malignant nasopharyngeal carcinoma received combined surgical and radiological treatment between 1965 and 1981. Additional cryotherapy was performed in 14 of these patients. The favourable survival rates of the latter, compared with those who had been subjected to radiological treatment alone, indicate the usefulness of this supplemental therapeutic procedure. Its effect could have purely local causes (destruction of the primary tumour prior to radiotherapy) or possibly involve certain immunological processes already demonstrated in other tumour types.
