신생병원의 5년 유방암 치료 경험: 임상 데이터 웨어하우스를 이용한 분석

Abstract

Purpose This study is to review the initial 5-years of breast cancer management in a single hospital using the clinical data warehouse (CDW) Methods: We reviewed the electronic medical records of 754 patients with breast cancer who were treated by a single surgeon between June 2003 and December 2007 in Seoul National University Bundang Hospital We analyzed the epidemiological, clinical and therapeutic profiles of the breast cancer patients which were encoded and stored at the CDW Results: The mean age of the patients was 49.3 years and the peak incidence was in the fifth decade (36.6%) Symptomatic breast cancer was 74.6% and screening-detected breast cancer was 25.4%. Breast conserving surgery (BCS) was performed in 54 1% of all cases and the BCS rate increased annually Immediate reconstruction after mastectomy was performed in 62 cases (17.7%). Sentinel lymph node (SLN) biopsy for nodal staging was performed in 501 cases (72 1%) and 160 cases (23 0%) underwent complete axillary lymph node dissection The proportion of in situ and early stage invasive breast cancer was 85.0%. Six hundred and ninety three patients (92.5%) received more than one adjuvant therapy Thirty one patients experienced local or systemic relapse after surgery and ipsilateral breast tumor recurrence (IBTR) occurred in 6 cases. The median follow-up penod was 29.5 months Two-year and 3-year disease-free survival rates were 95 9% and 94.4% Conclusion. BCS and SLN biopsy continuously increased and immediate reconstruction after mastectomy was performed widely. Most patients received more than one adjuvant therapy. Moreover, we saved the time and human power to review the medical record by using the CDW
