Breast cancer is the second most common cancer in Korean women and its incidence has increased. Among the various treatment methods for breast cancer, chemotherapy plays an important role. The use chemotherapy to treat breast cancer began at the mid 20th century and first combination chemotherapy was conducted in mid 1970s. This chemotherapy reduced breast cancer mortality up to 25~30%, anthracycline and taxane based chemotherapeutic regimens are widely used. Chemotherapy could be classified to neoadjuavnt, adjuvant and palliative setting according to its aim and role. In this review, various drug therapeutic options and their backgrounds are considered based on neoadjuvant, adjuvant and metastatic systemic therapies

Purpose: A chemotherapy response assay test is performed to evaluate the degree of tumor growth inhibition by a chemotherapeutic agent. Several studies have been done on its usefulness; however, to the best of our knowledge, only a few studies concerning the relationship between chemotherapy response assay test results and breast cancer patients’ prognoses have been conducted. Thus, we performed this study to analyze this relationship. Methods: Among breast cancer patients who underwent curative surgery and neoadjuvant or adjuvant chemotherapy between August 2004 and December 2009, 102 were enrolled in this study. Chemotherapeutic regimens for patients were doxorubicin plus taxane or doxorubicin plus cyclophosphamide followed by taxane. We divided these patients into two groups (sensitive group [n=19] and resistant group [n=83]) and analyzed the relationship between chemosensitivity results and patient prognosis. Results: The sensitive group was associated with poor disease-free survival (DFS) (p=0.003) and overall survival (OS) (p<0.001). No significant differences were observed in tumor histology (p=0.548),tumor size (p=0.479), number of metastatic lymph nodes (p=0.326), histologic grade (p=0.077), or nuclear grade (p=0.216) between the two groups. However, in respect to molecular subtype, the HER2-positive type and triple negative breast cancer were more frequently observed in the sensitive group (p=0.001). In a univariate and multivariate analysis for DFS, doxorubicin sensitivity was significantly associated with a poor prognosis (p<0.05). Conclusion: Better chemosensitivity results are associated with a poor prognosis in breast cancer patients who have undergone anthracycline- and taxane-based chemotherapy, however, examination of additional cases and the use of a longer study period are needed.

Purpose: Laparoscopic cholecystectomy (LC) for asymptomatic gallbladder disease has been increasing since 1990 due to the development of LC technique. Moreover, it might be considered when someone with asymptomatic gallbladder disease needs emergency operation due to acute abdomen such as acute appendicitis. The aim of this study is to identify the efficacy of concurrent laparoscopic appendectomy with cholecystectomy. Methods: From January 1997 to June 2009, 40 patients underwent laparoscopic appendectomy with cholecystectomy at Ewha Womans University Mokdong Hospital. 40 patients were enrolled in this study. We analyzed, retrospectively, clinical and diagnostic information, time and open conversion rate in operation, length of postoperation hospital stay, and complication rate. Results: The mean age was 44.53±15.34 and male to female ratio was 1 to 1.86. 5% of all patients underwent abdominal surgery and 20% of all patients had associated diseases. Most common associated symptoms and final diagnosis were right lower abdominal pain (72.5%) and simple gallbladder stone (62.5%). Mean operation time was 98.75±33.14 min. and there was no open conversion. Mean length of postoperation hospital stay was 5±2 days. There was one (2.5%) postoperative complication. Conclusion: Combined operation of laparoscopic cholecystectomy during laparoscopic appendectomy can be a good modality for patients with chronic gallbladder disease.
