Alveolar soft part sarcoma (ASPS) is a rare form of soft tissue sarcoma, and frequently, metastases are found at diagnosis. In patients with metastatic or unresected ASPS, systemic treatment is extremely limited, because conventional chemotherapeutic agents have not been effective in most cases. A novel agent inhibiting angiogenesis, pazopanib, has been proven to be effective for metastatic soft tissue sarcoma in a second-line setting. However, the efficacy of pazopanib in ASPS has not yet been reported. A 22-year-old man presented with right calf ASPS and multiple lung metastases. Pazopanib as a second-line treatment showed significant tumor response. To the best of our knowledge, this is the first report of the effectiveness of pazopanib in ASPS.

Autism spectrum disorder (ASD) remains unexplained and untreated despite the high attention of research in recent years. Aside from its various characteristics is the baffling male preponderance over the female population. Using a validated animal model of ASD which is the telomerase reverse transcriptase overexpressing mice (TERT-tg), we conducted ASD-related behavioral assessments and protein expression experiments to mark the difference between male and females of this animal model. After statistically analyzing the results, we found significant effects of TERT overexpression in sociability, social novelty preference, anxiety, nest building, and electroseizure threshold in the males but not their female littermates. Along these differences are the male-specific increased expressions of postsynaptic proteins which are the NMDA and AMPA receptors in the prefrontal cortex. The vGluT1 presynaptic proteins, but not GAD, were upregulated in both sexes of TERT-tg mice, although it is more significantly pronounced in the male group. Here, we confirmed that the behavioral effect of TERT overexpression in mice was male-specific, suggesting that the aberration of this gene and its downstream pathways preferentially affect the functional development of the male brain, consistent with the male preponderance in ASD.

PURPOSE: The aim of this study was to identify prognostic factors in stage IVB colorectal cancer in elderly patients, focusing on the influence of treatment modalities, including palliative chemotherapy and primary tumor resection. METHODS: A cohort of 64 patients aged over 65 years who presented with stage IVB colorectal cancer at the Gangneung Asan Hospital between July 1, 2001, and December 31, 2009, was analyzed. Demographics, tumor location, tumor grade, performance status, levels of carcinoembryonic antigen (CEA), level of aspartate aminotransferase (AST), and distant metastatic site at diagnosis were analyzed. Using the treatment histories, we analyzed the prognostic implications of palliative chemotherapy and surgical resection of the primary tumor retrospectively. RESULTS: The cohort consisted of 30 male (46.9%) and 34 female patients (53.1%); the median age was 76.5 years. Primary tumor resection was done on 28 patients (43.8%); 36 patients (56.2%) were categorized in the nonresection group. The median survival times were 12.43 months in the resection group and 3.58 months in the nonresection group (P < 0.001). Gender, level of CEA, level of AST, Eastern Cooperative Oncology Group performance status, tumor location, and presence of liver metastasis also showed significant differences in overall survival. On multivariate analysis, male gender, higher level of CEA, higher AST level, and no primary tumor resection were independent poor prognostic factors. In particular, nonresection of the primary tumor was the most potent/poor prognostic factor in the elderly-patient study group (P = 0.001; 95% confidence interval, 2.33 to 21.99; hazard ratio, 7.16). CONCLUSION: In stage IVB colorectal cancer in elderly patients, resection of the primary tumor may enhance survival.

BACKGROUND/AIMS: The aims of this study were to determine subgoups of functional dyspesia and to evaluate the short-term effect of cisapride in patients with functional dyspepsia in Korea. METHODS: 1025 patients, with a mean age of 42.6 years, with symptoms of functional dyspepsia, were recruited consecutively and upper gastrointestinal symptoms were investigated by interview in 41 hospitals in Korea. In an open, multicenter trial, 1025 patients received Smg of cisapride three times a day (TID) for at least .2 weeks for the treatment of symptoms of functional dyspepsia. When necessary, the dose of cisapride was increased to 10mg TID and the duration of therapy was extended to 4 weeks. RESULTS: The most frequently reported symptoms of functional dyspepsia were epigastric discomfort or fullness (85%), bloating (70%), belching (53%), early satiety (52%) and epigastric pain (46%) retrospectively. Subgroups of functional dyspepsia were as follows; dysmotility-like 73.5%, ulcer-like 39.7%, reflux-like 13.0%, and unspecified dyspepsia 14.0%. However, 33.2% of subjects with functional dyspepsia could be classified into more than one subgroup. Upper gastrointestinal symptoms were decreased to average 50.3% (range; 42.2 to 59.2%) after 2 weeks of cisapride treatment and to 25% (19.2 to 29.9%) after 4 weeks. cisapride therapy resulted in good or excellent improvement in 59.0% of the patients after two weeks, in 75% of patients after 4 weeks. Adverse events were occurred in 52 patients (5.8% of all patients), most commonly, loose stools or diarrhea (3.5%), abdominal pain (1.1%), and dizziness (0.3%). The majority of adverse events was mild and transient in nature and led to premature discontinuation of treatment in 4 patients. CONCLUSIONS: Although the majorities of patients with functional dyspepsia have dysmotility like symptoms in Korea, there is such overlap among the dyspepsia subgroups. Most patients responded well to a short therapeutic trial with cisapride without significant side effects.
