Headache characteristics and brain metastases prediction in cancer patients.
The aim of this study was to evaluate the headache and other neurological symptoms and signs as guide predictors for the occurrence of brain metastases in cancer patients. We prospectively studied 54 cancer patients with newly appeared headache or with a change in the pattern of an existing headache during the recent months. All patients completed a questionnaire regarding headache's clinical characteristics and existence of accompanying symptoms. They also underwent a detailed neurological, ophthalmologic examination and brain neuroimaging investigation. Brain metastases were diagnosed in 29 patients. Univariate regression analysis showed an association between occurrence of brain metastases and nine clinical symptoms or signs. Multivariate regression analyses emerged only four of them as significant independent predictors. These were: bilateral frontal-temporal headache, more pronounced on the side of metastasis in cases of single metastases, with duration > or =8 weeks, pulsating quality and moderate to severe intensity (OR: 11.9; 95% CI. 2.52-56.1), emesis (OR: 10.2; 95% CI. 2.1-55.8), gait instability (OR: 7.4; 95% CI. 1.75-33.9) and extensor plantar response (OR: 12.1; 95% CI. 2.2-120.7). In conclusion, all cancer patients who manifest the above independent clinical predictors should be highly suspected for appearance of brain metastases and therefore should be thoroughly investigated.
