dc.description.abstract[한글] 배경: 유방암에서 수술후 항암치료는 무병생존율과 전체 생존율을 높이는 것으로 알려져 있으며, 세포 독성을 가진 항암제들이 조기폐경을 일으키는 것으로 알려져 있어, 본 연구에서는 폐경전 유방암환자에서 항암치료에 따른 무월경의 발생에 영향을 미치는 요소와 항암치료에 의한 무월경이 예후에 미치는 영향에 대해 알아보고자 하였다.방법: 1995년부터 2000년까지 본원 암센터를 내원하여 수술후 CMF (cyclophosphamide, methotrexate, fluorouracil) 또는 FAC(fluorouracil, adriamycin, cyclophosphamide) 항암치료조합으로 치료 받은 폐경전유방암환자 208명을 대상으로 무월경 발생율을 비교하며 무월경이 발생한 환자와 발생하지 않은 환자간의 무병생존율, 전체생존율의 차이를 비교하는 연구를 진행하였다.결과: 무월경이 발생한 군은 발생하지 않은 군에 비하여 연령이 유의하게 높았으며(44세(28세-53세) vs 36세(25-49세).p=0.000), Tamoxifen을 사용한 군에서 사용하지 않은 군에 비하여 무월경발생율이 유의하게 높았다.(59.6% vs 40.4%. p=0.026). 무월경발생군이 발생하지 않은 군에 비해 5년 무병생존율이 유의하게 높았으며(90.4 vs 80.5%. p=0.0239), 5년 생존율 역시 유의하게 높았다. (96.9% vs 86.7%. p = 0.0239 ).결론: 연령과 Tamoxifen의 추가적인 투여가 항암치료에 의한 무월경 발생의 유의한 예측인자였으며, 항암치료에 의한 무월경은 무병생존율과 전체생존율의 향상과 유의한 관계를 보였다. [영문]Background : Adjuvant chemotherapy is known to prolong disease-free survival(DFS) and overall survival(OS) for patients with breast cancer, and can induce premature menopause by the cytotoxicity of chemotherapeutic drug. We investigated the factors predicting chemotherapy related amenorrhea (CRA) and prognostic significance of CRA.Method : 208 premenopausal breast cancer patients who underwent adjuvant CMF(cyclophosphamide, methotrexate, fluorouracil) or FAC(fluorouracil, adriamycin, cyclophosphamide) chemotherapy after breast cancer surgery were enrolled between January 1995 and december 2000.Results: Patients with CRA group were older than non-CRA group.(median; 44years versus 36years). Addition of tamoxifen to chemotherapy significantly increased the development of CRA (59.6% vs 40.4%. p=0.026). Five-year disease-free survival rate was higher in CRA group compared with non-CRA group (90.4 vs 80.5%. p=0.0239), and five-year overall survival rate was also higher in CRA group compared with non-CRA group. (96.9% vs 86.7%. p = 0.0239 ). These survival advantages were found in hormonal receptor positive patients.Conclusion:. The most important predictors of CRA are age and the addition of tamoxifen to chemotherapy. CRA is likely to have an influence on DFS and OS in premenopausal breast cancer patients, and thus can be used as a predictive marker of effective chemotherapy in premenopausal patients.-
