title: [Calcium metabolism in patients with laryngeal cancer before and after radiotherapy].
abstract: We studied the levels of ionized calcium in the blood serum of patients with laryngeal cancer (LC) before and after radiotherapy. The levels were measured on the analyzer ICA-1 by ionoselective electrode. LC patients were found to have high pretreatment levels of ionized calcium in all LC locations. After radiotherapy these levels fell also in all locations, especially in the vocal part of the larynx. Thus, radiotherapy can be recommended as an independent treatment method in laryngeal cancer, especially in involvement of vocal part of the larynx. LC treatment efficacy can be assessed by comparing levels of ionized calcium before and after treatment.
