Abstract

Radical treatment of breast cancer does not protect patients from local recurrence and/or metastasis. For this reason regular follow-up after completed radical treatment seems to be an effective form of recurrence detection at the early, curable phase. This analysis shows use of Markov model for probability calculation with respect to incidence of local recurrence and metastasis and survival during 5-year follow-up. Based on Markov`s model it was shown that regularity of follow-up after operation due to breast cancer does not decrease the risk of failure occurence neither does it contribute to patient`s life prolongation. Furthermore, detection of failure - during follow-up after operation due to breast cancer - does not increase the chance of its cure. Therefore standard follow-up of asymptomatic patients after radical treatment of breast cancer can be reduced to history and physical examination.
