PURPOSE: The empirical use of a chemotherapy regimen shows different results in individual breast cancer patient treatment. Recent studies showed the effectiveness of the adenosine triphosphate-based chemotherapy response assay (ATP-CRA). However, little is known about the correlation between chemosensitivity and breast cancer molecular subtypes. Therefore, we investigated whether the result of ATP-CRA is associated with a molecular subtype of breast cancer. METHODS: Two hundred eighty-seven patients diagnosed with breast cancer and receiving ATP-CRA at Mokdong Hospital, Ewha Womans University between September 2007 and December 2010 were enrolled in this study. Hormone receptor status, HER2/neu expression, and results of chemosensitivity tests of the patients was analyzed. RESULTS: In all of four subtypes, the combination of two agents showed significant higher mean cell death rate than a single agent. Within the breast cancer cell lines in this study, the range of chemosensitivity response was very wide and varied for each patient. For this reason, the molecular subtype of breast cancer is inconclusive in choosing an effective chemotherapeutic agent and in vitro chemosensitivity test, prior to therapy, could be a useful method for planning chemotherapy for each patient. CONCLUSION: Chemosensitivity response to anticancer agents was found to vary depending on the individual breast cancer patients. The molecular subtype of breast cancer is inconclusive to choose the effective chemotherapeutic agent and the in vitro chemosensitivity test, prior to therapy, could be more useful for planning chemotherapy for each patient.

A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control, the surgeons participating in this trial had to have performed at least 50 cases each of laparoscopy-assisted distal gastrectomy and open distal gastrectomy and their institutions should have performed more than 80 cases each of both procedures each year. Fifteen surgeons from 12 institutions recruited 1,415 patients. The primary endpoint is overall survival. The secondary endpoints are disease-free survival, morbidity, mortality, quality of life, inflammatory and immune responses, and cost-effectiveness (ClinicalTrials.gov ID: NCT00452751).

The repair of abdominal aortic aneurysm (AAA) in patients with functioning renal transplant is critical because it is important to avoid ischemic and reperfusion injury to the transplanted kidney. Endovascular aneurysm repair (EVAR) avoids aortic cross clamping and can prevent renal graft ischemia. Here we report the endovascular management and outcome of AAA in two renal transplant patients using a bifurcated aortic stent graft. One patient underwent EVAR using a small amount of contrast (30 mL) due to decreased renal function resulting from chronic rejection. Another patient had EVAR performed with iliac conduit because of the heavily calcified, stenotic lesion of external iliac artery. EVAR in patients with a renal transplant is a feasible option without impairing renal arterial flow.

6.Biliary injury after cholecystectomy in a patient with severe right liver atrophy.
Journal of the Korean Surgical Society 2013;84(3):185-188
We report a case of bile fistula after cholecystectomy in a patient with severe right liver atrophy, which was managed by endoscopic nasobiliary drainage and conservative treatment. The patient was a 76-year-old man with a sudden onset in the right flank and abdominal pain. Computed tomography revealed calculous cholecystitis and severely atrophied right lobe of the liver. Gallbladder was located in the superior-posterior portion of the liver as opposed to the normal position. The patient underwent cholecystectomy and showed massive bleeding and bile leakage at the gallbladder bed during operation. A bile fistula was detected three days after surgery, which was managed by interventional bile drainage. Right liver agenesis or severe atrophy is rare. Additionally, the report of combined bile duct injury after cholecystectomy in these settings is extremely rare.

PURPOSE: To identify the risk factors of major adverse cardiac event (MACE) in patients with chronic atherosclerotic lower extremity ischemia (CALEI) undergoing revascularization without noninvasive stress testing (NIST). METHODS: From January 2007 to January 2012, patients with CALEI who underwent revascularization were retrospectively reviewed. Emergent operations, revision procedures for previous surgery, or patients with active cardiac conditions were excluded. NIST was not performed for patients without active cardiac conditions. Cardiac risk was categorized into low, intermediate and high risk, according to the Lee's revised cardiac risk index. MACE was defined as acute myocardial infarction or any cardiac death within 30 days after surgery. RESULTS: A total of 459 patients underwent elective lower extremity revascularization procedures (240 open surgeries, 128 endovascular procedures, and 91 hybrid surgeries). The treated lesions comprised of 18% aorto-iliac, 58% infrainguinal, and 24% combined lesions. With regard to cardiac risk, low-, intermediate- and high risks were 67%, 32% and 2%, respectively. MACE was developed in 7 patients (2%). High or intermediate risk group by the Lee's index was related to postoperative MACE. Subgroup analysis for open surgery or hybrid surgery group identified female gender as an independent risk factor of MACE (P = 0.049; odds ratio, 5.168; confidence interval, 1.011 to 26.423). CONCLUSION: The Lee's index was a useful predictor of MACE. MACE is more common in female patients than male patients after open or hybrid surgery. Routine preoperative NIST is not suggested for all patients undergoing revascularization for CALEI, especially for those in the low risk group.

PURPOSE: It is increasingly being recognized that the lymph node ratio (LNR) is an important prognostic factor for gallbladder carcinoma patients. The present study evaluated predictors of tumor recurrence and survival in a large, mono-institutional cohort of patients who underwent surgical resection for gallbladder carcinoma, focusing specifically on the prognostic value of lymph node (LN) status and of LNR in stage IIIB patients. METHODS: Between 2004 and 2011, 123 patients who underwent R0 radical resection for gallbladder carcinoma at the Chonnam National University Hwasun Hospital were reviewed retrospectively. Patients were staged according to the American Joint Committee on Cancer 7th edition, and prognostic factors affecting disease free survival, such as age, sex, comorbidity, body mass index, presence of preoperative symptoms, perioperative blood transfusion, postoperative complications, LN dissection, tumor size, differentiation, lymph-vascular invasion, perineural invasion, T stage, presence of LN involvement, N stage, numbers of positive LNs, LNR and implementation of adjuvant chemotherapy, were statistically analyzed. RESULTS: LN status was an important prognostic factor in patients undergoing curative resection for gallbladder carcinoma. The total number of LNs examined was implicated with prognosis, especially in N0 patients. LNR was a powerful predictor of disease free survival even after controlling for competing risk factors, in curative resected gallbladder cancer patients, and especially in stage IIIB patients. CONCLUSION: LNR is confirmed as an independent prognostic factor in curative resected gallbladder cancer patients, especially in stage IIIB gallbladder carcinoma.

PURPOSE: The aim of this study was to investigate the current status of the use of antiadhesive agents (AAdAs) via a questionnaire and to discuss the availability of AAdAs. METHODS: The survey was sent to a list of members that was approved by the Korean Gastric Association. The survey included questions on AAdA use by surgeons, the type of AAdAs used, and the reasons for not using AAdAs. Surgeons were also asked to describe complications related to AAdAs, and the reliability of its use. RESULTS: The response rate was 21%. The rates of frequent use stratified by procedure were 26.9% (14/52) for open gastrectomy, 5.9% (3/51) for laparoscopic gastrectomy, and 31.5% (17/54) for surgery for postoperative bowel obstruction (P < 0.01). After including data from the occasional use group, the corresponding values were 51.9% (27/52), 19.6% (10/51), and 70.4% (38/54), respectively (P < 0.01). Sefrafilm and Guardix were most commonly used for open procedures. Guardix and Interceed were most commonly used for laparoscopic surgery. The primary reasons for nonuse of AAdAs were ineffectiveness and high cost. Ten percent (4/40) of surgeons observed complications associated with AAdAs. A minority (17.3%, 9/52) had positive attitudes toward AAdAs. The majority of respondents expressed neutral (73.1%, 38/52) or negative (9.6%, 5/52) attitudes toward AAdAs. CONCLUSION: The low use rates of AAdAs in gastric cancer surgery may be attributable to perceptions that AAdAs are ineffective, unreliable, and costly. We anticipate the emergence of promising antiadhesive strategies that reach far beyond the limitations of current products.

PURPOSE: The aim of our study is to evaluate the factors affecting surgical margin positivity among patients with invasive ductal breast cancer who underwent breast-conserving surgery (BCS) after preoperative diagnostic core biopsy. METHODS: Two hundred sixteen patients with stage I, II invasive ductal breast carcinoma who had histological diagnosis with preoperative tru-cut biopsy and underwent BCS were included in the present study. Potential factors that affect the positive surgical margin were analyzed. In univariate analysis, the comparisons of the factors affecting the surgical margin positivity were made by chi-square test. Logistic regression test was used to detect the independent factors affecting the surgical margin positivity. RESULTS: Positive axillary lymph node (odds ratio [OR], 8.2; 95% confidence interval [CI], 3.01 to 22.12), lymphovascular invasion (LVI; OR, 3.9; 95% CI, 1.62 to 9.24), extensive intraductal component (EIC; OR, 6.1; 95% CI, 2.30 to 16.00), presence of spiculation (OR, 5.1; 95% CI, 2.00 to 13.10) or presence of microcalcification in the mammography (OR, 13.7; 95% CI, 4.04 to 46.71) have been found to be the independent and adverse factors affecting surgical margin positivity. CONCLUSION: Considering decision making for the extent of the excision and for achieving negative surgical margin before BCS, positive axillary lymph node, LVI, EIC, spiculation or microcalcification in mammography are related as predictor factors for positive surgical margin.
