title: [Urinary magnesium levels in precancerous conditions and various stages of squamous cell carcinoma of the larynx].
abstract: In 100 cases with different stages of planoepithelial laryngeal cancer and in 13 precancerous changes the urine magnesium levels were examined two times by means of absorptive spectrometry before surgery and half a year after. In precancerous period group (I stage according to WHO) no differences were found in comparison to the control group. As the disease progressed the urine magnesium level deteriorated according to the cancer stages. In IV stage the level was the lowest (P less than 0.01). The normalization of the urine magnesium level was found in some cases 6 months after surgery and radiotherapy.
