Metastatic breast cancer patients are usually exposed to taxane and anthracycline as neoadjuvant, adjuvant and palliative chemotherapeutic agents. This study was designed to determine the efficacy and safety of the use of a gemcitabine and cisplatin (GP) combination treatment in patients with metastatic breast cancer that were pretreated with anthracycline and taxane.
We evaluated the use of a GP regimen (1,000 mg/m2 gemcitabine administered on days 1 and 8 plus 60 mg/m2 cisplatin administered on day 1 every 3 weeks) in 38 breast cancer patients who had received prior chemotherapy with anthracycline and taxane as an adjuvant or neoadjuvant therapy, or as a palliative therapy.
The median patient age was 49 years (age range, 35~69 years). The overall response rate was 28.9% in 11 patients (95% confidence interval [CI], 14~44%). The median time to progression was 5.2 months (95% CI, 3.6~6.8 months). Median survival was 19.5 months (95% CI, 11.2~27.8 months). Major grade 3/4 hematological toxicity was due to leukopenia (36 of 157 cycles, 23.1%). Non-hematological toxicity was rarely severe; grade1/2 nausea and vomiting were observed in 37.8% of the patients. There were no treatment related deaths.
Our results suggest that the use of gemcitabine plus cisplatin appears to be effective and has an acceptable toxicity profile in patients with advanced breast cancer that have been pretreated with anthracycline and taxane.

We wanted to assess the effectiveness and safety of combination chemotherapy with paclitaxel, 5-fluorouracil (5-FU) and cisplatin for treating advanced gastric cancer.
Patients with metastatic or recurrent gastric cancer were entered into this study. Paclitaxel at a dose of 135 mg/m2 on day 1, 5-FU 1 g/m2/day in a 24 hour continuous infusion from day 1 to day 4 and cisplatin 60 mg/m2 on day 1 were administered. This regimen was repeated every 3 weeks.
A total of 34 patients were enrolled in this study. Among them, 33 patients were finally evaluable for their response. 17 (51.5%) patients had a partial response (95% CI: 26.0~77.0%). The median duration of overall survival was 13.2 months. Grade 3 or 4 neutropenia and thrombocytopenia were observed in 15.2% and 1.1% of all the cycles, respectively. Grade 3 stomatitis and neurotoxicity were observed in 20.6% and 1.1% of all patients, respectively. Grade 4 non-hematologic toxicity was not observed.
The regimen of paclitaxel, 5-FU and cisplatin demonstrated activity and accepatable toxicity for treating metastatic gastric cancer.

Following the introduction of a multimodal approach to diagnosis and treatment, the prognosis of rhabdomyosarcoma (RMS) has markedly improved over the last three decades. However, there are few data on treatment outcomes in Korean patients.
We performed a retrospective analysis of 77 patients with RMS diagnosed and treated at Seoul National University Children's Hospital between 1986 and 2005.
The overall 5-year survival and event-free survival rates for all patients were 77% and 59%, respectively. The Intergroup Rhabdomyosarcoma Study clinical grouping and initial response to treatment (20-week response) were important prognostic factors.
The outcome of childhood RMS was closely associated with the initial staging and the initial response to treatment. Modulating therapies according to initial responses and risk factors is critical, and new treatment strategies for high-risk patients are needed.

Although platinum based chemotherapy is known to improve the survival duration for the patients with non-small cell lung cancer, the role of platinum for elderly patient is not yet clear. We administered gemcitabine and carboplatin combination therapy to elderly patients with NSCLC. The aim of this study was to evaluate the efficacy and toxicities of this regimen for elderly patients.
The eligibility criteria were as follows: pathologically confirmed NSCLC, an age ≥65 years, advanced disease with stage IIIB or IV and the patients were chemotherapy-naive. The treatment regimen was as follows; gemcitabine 1,000 mg/m2 was administered on days 1 and 8 and carboplatin AUC=5 was administered on day 1. This regimen was repeated every 3 weeks. The efficacy was evaluated in terms of the response rate, the time to progression and the overall survival duration.
From Dec 2001 to Feb 2005, a total of 20 patients were entered into this study. The median patient age was 68 years (range: 65~75). 19 patients were evaluable for their treatment response. A partial response was obtained in 8 patients (response rate: 42.1%, 95% CI: 19.4~64.8%). The median time to progression and the survival duration were 136 days and 453 days, respectively. Among a total of 65 cycles of treatment, grade 3 or 4 leukopenia and thrombocytopenia were observed in 7.7% and 13.9% of the cycles, respectively. Grade 3 or 4 vomiting was observed in 7.7% of the cycles. Grade 3 skin rash developed in 1.5% of the cycles. 1 patient died of septic shock after chemotherapy.
Gemcitabine and carboplatin combination chemotherapy was relatively safe and effective for treating elderly patients with NSCLC.

Anthracycline can effectively treat hematologic malignancies, but has significant risk of cardiotoxicity. We measured the clinical correlation between brain natriuretic peptide (BNP) and anthracycline-induced cardiotoxicity.
Between March 2005 and March 2007, 86 patients with acute leukemia, malignant lymphoma, or multiple myeloma receiving systemic chemotherapy with anthracycline were enrolled in the Department of Hemato-oncology, Kosin University Gospel Hospital. We investigated the relationship between BNP level and cardiotoxicity through echocardiography, electrocardiography, BNP levels, and symptoms of heart failure at each chemotherapy cycle.
Of the 86 participants (mean age, 48.5 years; range 20~65 years), cardiotoxicity developed in 21 patients (24.4%), with 2 patients showing arrhythmia only, 17 patients with transient aspects of heart failure, and 2 patients with chronic heart failure. Cardiotoxicity related to serum BNP level, age, cumulative dose of anthracycline, accompanying chronic disease, and elevated level of troponin-I. Heart failure was more common if BNP levels reached 100 pg/ml at least once.
The clinical correlation between BNP and cardiotoxicity was significant in patients with systemic anthracycline chemotherapy. A prospective clinical trial will be needed to identify the causal relationship between serum BNP level and cardiotoxicity.

Bone Morphogenetic Proteins (BMPs) are members of the TGF-β superfamily and it has been demonstrated that BMPs enhance migration, invasion and metastasis. The purpose of this study was to identify the association between the serum BMP-2 level and the progression status of gastric cancer.
Fifty-five patients with metastatic gastric cancer (metastatic disease group), six patients with early gastric cancer without lymph node metastasis (the EGC group), and ten healthy control subjects were enrolled in this study. The serum BMP-2 level was quantified by use of a commercially available ELISA kit. In EGC group patients and patients with metastatic disease, whole blood was obtained before endoscopic mucosal resection and before the commencement of a scheduled cycle of systemic chemotherapy, respectively.
No significant difference in the mean serum BMP-2 levels was observed between the control subjects and the EGC group patients (87.95 pg/ml for the control subjects and 84.50 pg/ml for the EGC group, p=1.0). However, the metastatic disease group patients had a significantly higher level of serum BMP (179.61 pg/ml) than the control subjects and EGC group patients (87.95 pg/ml for the control subjects and 84.50 pg/ml for the EGC group, p<0.0001). Moreover, the mean serum BMP-2 level from patients with a bone metastasis was significantly higher than the mean serum BMP-2 level from patients without a bone metastasis (204.73 pg/ml versus 173.33 pg/ml, p=0.021).
BMP-2 seems to have a role in progression to metastatic disease in gastric cancer, especially in the late stage of tumorigenesis, including invasion and metastasis. BMP-2 may facilitate bone metastasis in gastric cancer. To confirm these findings, further studies are required with tissue specimens and the use of a cancer cell line.

Lymphatic spread of tumor is an important prognostic factor for patients with non-small cell lung carcinoma (NSCLC). Vascular endothelial growth factor-C (VEGF-C) and VEGF-D play important roles in lymphangiogenesis via the VEGF receptor 3 (VEGFR-3). We sought to determine whether VEGF-C, VEGF-D and VEGFR-3 are involved in the clinical outcomes of patients with resected NSCLC.
Using immunohistochemical staining, we investigated the protein expressions of VEGF-C, VEGF-D and VEGFR-3 in the tissue array specimens from patients who underwent resection for NSCLC. The immunoreactivity for p53 was also examined. The clinicopathological implications of these molecules were statistically analyzed.
Analysis of a total of 118 specimens showed that VEGF-C, VEGF-D and their co-expression were significantly associated with more advanced regional lymph node metastasis (p=0.019, p=0.044 and p=0.026, respectively, N2 versus N0 and N1). A VEGFR-3 expression had a strong correlation with peritumoral lymphatic invasion (p=0.047). On the multivariate analysis for survival and recurrence, pathologic N2 lymph node metastasis was the only independent prognostic factor, but none of the investigated molecules showed any statistical correlation with recurrence and survival.
The present study revealed that high expressions of VEGF-C and VEGF-D were strongly associated with more advanced regional lymph node metastasis in patients with resected NSCLC.

Metastatic extragenital cancer that spreads to the uterus is rare. When it occurs, the extragenital primary disease is often in the breast or gastrointestinal tract. We report here on a case of hepatocellular carcinoma (HCC) that metastasis to the uterus. The patient was admitted for evaluation of a pelvic mass. The serum alpha-fetoprotein level was highly elevated. Magnetic resonance imaging of the abdomen and pelvis showed hepatic and uterine masses. The patient underwent surgical treatment. The histopathologic findings and immunohistochemical staining results of the uterine mass were char acteristics of metastatic HCC. The endometrium and both ovaries were free of tumor. Up to now, there have been only two cases of uterine metastasis from HCC reported in the English literature. This case is the first documented instance of a metastatic uterine tumor from HCC that spared both ovaries.

Rare Site Hepatocellular Carcinoma Metastasis
Primary gastric choriocarcinoma (PGC) is a rare tumor, and its pathogenesis is still uncertain. Most PGCs have been reported to possess an adenocarcinoma component of variable extent, and pure PGC is especially rare. The diagnosis of PGC is confirmed by exhibition of choriocarcinomatous components on biopsy and exhibition of β-hCG positive cell on immunohistochemical stain and elevation of the serum β-hCG. Moreover it must be confirmed that no other site including gonads displays any tumor masses. The PGC tends to be more invasive and to have early metastasis. The median survival is known to be less than several months. We report two cases. The first case was a 62 year-old man who was diagnosed as advanced gastric cancer (AGC) by endoscopic biopsy with hepatic metasasis and received palliative chemotherapy with modified FOLFOX regimen and Genexol plus cisplatin regimen. He underwent subtotal gastrectomy due to perforation of the stomach during chemotherapy. On post-operative biopsy, He was re-diagnosed as PGC and received another palliative chemotherapy modified FOLFIRI, BEP, EMACO, VIP. However, multiple liver metastases were aggravated, and also serum AFP level increased. Ultimately, the paient died 10 months after initial diagnosis. Another case was a 45 year-old man. On endoscopic biopsy, he was diagnosed as AGC of adenocarcinoma. On Chest and Abdomen CT, multiple pulmonary and hepatic metastasis were also confirmed. On liver biopsy, He was diagnosed as PGC. The immunohistochemical stains were performed and the results were cytokeratin positive, EMA negative and β-hCG weak positive. The serum β-hCG level was highly elevated. BEP, VIP and EMA/CO combination therapy were administered, but he died at 12th months after the initial diagnosis.
