[The assessment of the dependence between antigen CA 125 and nicotinism in patients with benign ovarian tumors including endometrial cysts].

Unlabelled: Cancer antigen CA-125 is a marker that is primarily used to differentiate benign from malignant tumors as well as to monitor response to ovarian cancer treatment. Taken as a separate marker, it displays low sensitivity and specificity in ovarian cancer diagnosis; however, in combination with other markers it may be successfully applied especially in postmenopausal women. Elevated CA-125 levels in blood serum indicate cancerous as well as non-cancerous diseases. Research aiming to determine environmental factors that may have influence on antigen CA-125 level, and thus on the assessment of this marker's application in gynecological and oncological diseases continues.
Objectives: the aim of the present research is an attempt to estimate the influence of nicotinism on antigen CA-125 in blood serum in patients with diagnosed benign ovarian tumors including endometrial cysts.
Material and Methods: 174 women aged 16-85 years with diagnosed benign ovarian tumor were qualified for the study. In all patients level of antigen CA-125 in blood serum was assessed preoperatively and nicotinism history was taken. Also transvaginal ultrasound was performed to obtain preliminary diagnosis. Smoking and non-smoking patients were classified into two groups, namely of those with histopathologically confirmed cysts of endometrial type and those with non-endometrial benign ovarian tumors.
Results: statistical analysis did not prove any dependence between the CS-125 antigen level and nicotinism in any of these groups. Also additional analysis with division into premenopausal and postmenopausal patients did not determine any statistically significant dependence.
Conclusion: Nicotinism does not significantly influence the CA-125 antigen level in patients with benign However, the connection between the addiction severity and its influence on antigen CA-125 in blood serum cannot be excluded. ovarian tumors or endometrial cysts.
