Comparison of Premenopousal and Postmenopausal Breast Cancer Cases in Terms of Demographic and Prognostic Factor

Abstract

Breast cancer is the second most common type of cancer in the world and it is the most frequently seen cancer type in women. In early stages involving small and monocenter tumors, surgical treatment with breast conserving surgery followed by radiotherapy is the most preferred treatment regimen. Similar to the size of the tumor, several prognostic factors determine survival in breast cancer patients. This study was conducted to evaluate prognostic factors and their relationship to the menopausal status of the patients. University Ataturk Training and Research Hospital, Izmir, Turkey with 573 patients diagnosed with breast cancer between January 2006 and December 2012. Patient age, menopausal status, tumor location surgical treatment information, treatment regimen was gathered using the registry system of the hospital. Male breast cancer patients and patients with insufficient data were excluded. The mean (±SD) age of the study population was determined as 55.9 (±12.9). Most of the patients (65.3%) included in the study were identified as post-menopausal (n=199). Post-menopausal women were detected with larger tumors (p=0.048), at a later stage (p=0.037), with higher KI-67 index (p=0.015) and received more adjuvant hormone therapy (p=0.036) when compared to the pre-menopausal women. Multi-centered studies are needed to evaluate prognostic factors and their relationship to the menopausal status of the patients in order to plan more precise personal treatment regimens.
