PURPOSE: The combination of gemcitabine and cisplatin (GP) has been shown to be safe and efficacious for patients with metastatic breast cancer (MBC), pretreated with anthracyclines and taxanes. We assessed the efficacy and safety of weekly low-dose GP in patients with MBC. METHODS: We collected clinicopathological data from MBC patients who had been treated with gemcitabine, 800 mg/m2 plus cisplatin, 30 mg/m2 intravenously, on days 1 and 8 every 3 weeks, between January 2001 and November 2011 in Korea. RESULTS: The analysis included 294 patients previously treated anthracycline-xand taxane-based chemotherapies prior to GP (median age, 48 years [range, 28-78 years]; median follow-up duration, 63.9 months). Seventeen patients (5.8%) discontinued GP because of toxicities. The median progression-free survival (PFS) was 3.9 months (95% confidence interval [CI], 3.394.4 months) and the median overall survival (OS) was 27.7 months (95% CI, 17.6-37.8 months) months. Statistically significant factors for PFS were performance status (Eastern Cooperative Oncology Group, > or =2 vs. <2; hazard ratio [HR], 1.37; 95% CI, 1.02-1.85; p=0.037), distant disease-free interval (DDFI; < or =2 years vs. >2 years; HR, 1.66; 95% CI, 1.28-1.95, p<0.001), time interval from the diagnosis of metastasis to GP therapy (< or =1 year vs. >1 year; HR, 1.48; 95% CI, 1.13-1.95, p<0.001), and presence of brain metastasis (HR, 1.47; 95% CI, 1.03-2.10; p=0.031). Similarly, DDFI (< or =2 years vs. >2 years; HR, 2.07; 95% CI, 1.36-3.14; p<0.001) and the presence of brain metastasis (HR, 2.14; 95% CI, 1.27-3.61; p=0.004) were important factors for OS after GP treatment. CONCLUSION: Weekly low-dose GP chemotherapy appears safe and effective for heavily pretreated MBC patients.

PURPOSE: The aim of study was to evaluate the usefulness of serum HER2 as a therapeutic response indicator in patients with HER2 positive metastatic breast cancer (MBC). MATERIALS AND METHODS: The levels of serum HER2 and CA15.3 were assayed in 148 serial serum samples from 50 HER2 positive MBC patients at both the baseline and follow-ups. The changes in the levels of serum HER2 and CA15.3 in relation to the tumor responses to the various chemotherapy regimens were monitored. RESULTS: The levels of serum HER2 and CA15.3 were elevated in 82% and 62% of tissue HER2 positive patients, respectively, prior to therapies, with the changes in both tumor markers showing statistical significance in relation to the tumor responses (p<0.01) in patients with elevated baseline serum markers. CONCLUSION: The level of serum HER2 could be a valuable response indicator, not only for trastuzumab containing therapy, but also for other common MBC chemotherapeutic agents. Also, as it is more frequently elevated, the serum level of HER2 may also be a more useful tumor marker than CA15.3 in HER2 positive MBC.

Cryptococcosis is a systemic opportunistic infection mostly occurred in immunosuppressed patients. Pulmonary cryptococcosis in immunocompetent host is usually localized and self-limiting disease. Pulmonary nodule or mass is the most common radiologic finding, however involvement of mediastinal lymph nodes is rare. Here we report a case of pulmonary cryptococcosis with massive mediastinal lymph nodes involvement in immunocompetent host.

Acral metastasis to the finger is a very rare phenomenon. We report herein a case of cutaneous acrometastasis to the right 5th finger tip in a 36-year-old woman with metastatic breast cancer. The patient underwent a right modified radical mastectomy for T3N3 invasive ductal carcinoma and received adjuvant chemotherapy and radiotherapy. After 2 years, she developed metastasis to the brain, bones, and lungs. She was found to have a growing tender mass on the tip of right 5th finger. A well-demarcated, soft tissue mass was identified on sonography. Under the clinical impression of a possible benign process, the nodule was surgically removed. The pathologic finding was consistent with metastatic breast cancer. Immunohistochemical staining for estrogen receptor, progesterone receptor, and HER2 were all negative, as in the primary tumor. Radiation was given to the finger tip and systemic chemotherapy with capecitabine was tried for systemic metastatic disease.

We investigated the causes of inpatient death after intensive care unit (ICU) discharge and determined predictors of in-hospital mortality in Korea. Using medical ICU registry data of Seoul National University Hospital, we performed a retrospective cohort study involving patients who were discharged alive from their first ICU admission with at least 24 hours of ICU length of stay (LOS). From January 2011 to August 2013, 723 patients were admitted to ICU and 383 patients were included. The estimated in-hospital mortality rate was 11.7% (45/383). The most common cause of death was respiratory failure (n = 25, 56%) followed by sepsis and cancer progression; the causes of hospital death and ICU admission were the same in 64% of all deaths; sudden unexpected deaths comprised about one-fifth of all deaths. In order to predict in-hospital mortality among ICU survivors, multivariate analysis identified presence of solid tumor (odds ratio [OR], 4.06; 95% confidence interval [CI], 2.01–8.2; P < 0.001), hematologic disease (OR, 4.75; 95% CI, 1.51–14.96; P = 0.013), Sequential Organ Failure Assessment (SOFA) score upon ICU admission (OR, 1.08; 95% CI, 0.99–1.17; P = 0.075), and hemoglobin (Hb) level (OR, 0.67; 95% CI, 0.52–0.86; P = 0.001) and platelet count (Plt) (OR, 0.99; 95% CI, 0.99–1.00; P = 0.033) upon ICU discharge as significant factors. In conclusion, a significant proportion of in-hospital mortality is predictable and those who die in hospital after ICU discharge tend to be severely-ill, with comorbidities of hematologic disease and solid tumor, and anemic and thrombocytopenic upon ICU discharge.

PURPOSE: The risk for lymphedema (LE) after neoadjuvant chemotherapy (NCT) in breast cancer patients has not been fully understood thus far. This study is conducted to investigate the incidence and time course of LE after NCT. MATERIALS AND METHODS: A total of 313 patients with clinically node-positive breast cancer who underwent NCT followed by surgery with axillary lymph node (ALN) dissection from 2004 to 2009 were retrospectively analyzed. All patients received breast and supraclavicular radiation therapy (SCRT). The determination of LE was based on both objective and subjective methods, as part of a prospective database. RESULTS: At a median follow-up of 5.6 years, 132 patients had developed LE: 88 (28%) were grade 1; 42 (13%) were grade 2; and two (1%) were grade 3. The overall 5-year cumulative incidence of LE was 42%. LE first occurred within 6 months after surgery in 62%; 1 year in 77%; 2 years in 91%; and 3 years in 96%. In a multivariate analysis, age (hazard ratio [HR], 1.66; p < 0.01) and the number of dissected ALNs (HR, 1.68; p < 0.01) were independent risk factors for LE. Patients with both of these risk factors showed a significantly higher 5-year cumulative incidence of LE compared with patients with no or one risk factor (61% and 37%, respectively; p < 0.001). The addition of adjuvant chemotherapy did not significantly correlate with LE. CONCLUSION: LE after NCT, surgery, and SCRT developed early after treatment, and with a high incidence rate. More frequent surveillance of arm swelling may be necessary in patients after NCT, especially during the first few years of follow-up.

PURPOSE: Preoperative chemotherapy has been used to increase the rate of breast conserving surgery (BCS) in Caucasian women. However, whether it would also increase the rate of BCS in Korean women has not been verified. The aim of this study was to determine the effectiveness of preoperative chemotherapy to make BCS possible in Korean women who have locally advanced cancer without any increase of locoregional recurrence according to operation methods (BCS vs. mastectomy). METHODS: From August 2002 to April 2005, 205 patients with stage II or III breast cancer were enrolled in a phase III randomized trial of preoperative chemotherapy. Surgeons decided on the type of surgery (mastectomy or BCS) at initial diagnosis. By randomization, patients received four cycles of either docetaxel/capecitabine or doxorubicin/cyclophosphamide followed by surgery and crossover to the other treatment as postoperative chemotherapy. RESULTS: The mean tumor size was 3.29 cm and the mean breast volume was 489 cc at diagnosis. After preoperative chemotherapy, clinical response was shown in 76.0% of the patients. Of the 71 patients planned for a mastectomy at initial diagnosis, 27 patients underwent BCS (38.0%). Clinical T stage after preoperative chemotherapy, pathologic T size and lymphatic invasion were correlated with conversion to BCS. In multivariate analysis, only lymphatic invasion showed statistical significance. Locoregional disease-free survival did not statistically differ between the two operation methods for the patients who were planned for a mastectomy at the initial exam. CONCLUSION: This study showed that preoperative chemotherapy also increased the rate of BCS, while avoiding any increase of locoregional recurrence in Korean women with locally advanced breast cancer.

PURPOSE: The aim of this study is to evaluate stage IV breast cancer at the initial presentation by the review of a single institute' data. We also tried to figure out the factors to predict stage IV breast cancer. METHODS: We reviewed the prospectively collected database of 1,424 consecutive patients with primary breast cancer at the National Cancer Center in Korea from October 2000 to January 2005. RESULTS: The proportion of stage IV breast cancer was 2.7% (38/1,424). The median tumor size of the stage IV patients was 4.1 cm. The most common metastatic site was bone (47.4%) followed by lung (44.7%) and liver (36.8%). Metastases were found in 0.9% (6/672) of the T1 tumors, 2.4% (13/535) of the T2 tumors, 8.3% (4/48) of the T3 tumors, and 27.1% (13/48) of the T4 tumors (p<0.001). On multivariate analysis, the statistically significant predictors of distant metastasis were tumor size (> or =2 cm) (p=0.026), positive lymph node status (p<0.001), alkaline phosphatase (>104 IU/L) (p=0.013), aspartate transferase (>40 IU/L) (p=0.003) and CA15-3 (>32 U/mL) (p=0.025). CONCLUSION: Our study showed that the factors to predict distant metastasis of breast cancer were large size of tumor, positive lymph node status, elevated alkaline phosphatase, aspartate transferase and CA15-3. Therefore breast cancer patients with those clinical characteristics should be carefully evaluated to detect distant metastasis.

A 62-yr-old woman with an autosomal dominant polycystic kidney disease (ADPKD) was admitted to our hospital for further evaluation of intermittent fever, nausea and left flank discomfort. The computed tomography (CT) scan revealed a gas-forming, infectious cyst of approximately 8.1 cm in size in left kidney lower pole. Escherichia coli was identified from the cyst fluid culture examination. Her symptoms improved only after the concomitant use of intravenous ciprofloxacin and an intracystic irrigation of ciprofloxacin through a percutaneous cystostomy drainage. Our case presents the successfully treated emphysematous cyst infection with combination of intravenous antibiotics and intracystic antibiotic therapy instead of surgical management.
