A continuous predictor of overall survival was built taking into account well-known issues in microarray analysis, such as multiple testing and overfitting. A functional class scoring analysis was utilized to assess pathways/transcription factors for their association with overall survival. The prognostic value of genes that constitute our overall survival profile was validated on a fully independent, publicly available dataset of 118 well-defined primary serous ovarian cancers. Furthermore, functional class scoring analysis was also performed on this independent dataset to assess the similarities with results from
our own dataset. An 86-gene overall survival profile discriminated between patients with unfavorable and favorable prognosis (median survival, 19 versus 41 mo, respectively; permutation p-value of log-rank
statistic = 0.015) and maintained learn more its independent prognostic value in multivariate analysis. Genes that composed the overall survival profile were also able to discriminate between the two risk groups in the independent dataset. In our dataset 17/167 pathways and 13/111 transcription factors were associated with overall survival, of which 16 and 12, respectively, were confirmed in the independent dataset.
Conclusions Our study provides new clues to genes, pathways, and transcription factors that contribute to the clinical outcome of serous ovarian cancer and might be exploited in designing new treatment strategies.”
“Objective. The objective PKC412 clinical trial of this study was to AP26113 inhibitor determine the clinical presentations and management of thyroglossal duct cyst (TDC or thyroglossal tract remnant [TTR]) between children and adults and evaluate risk factors associated with recurrence after surgery for TDCs.
Study design. A retrospective study of all patients with TDCs managed in our department from
January 1998 through April 2008 was performed. All records were reviewed for age and sex, sizes and locations of cysts, diagnostic methods, surgical management, recurrences, and complications. Differences between children and adults and risk factors associated with recurrence were evaluated.
Results. A total of 106 patients (47 children and 59 adults) were treated for TDC. Of the children, 57.4% were male and 42.6% were female, whereas 50.8% of the adults were male and 49.2% were female. There were no significant differences in sex in either group (P > .49). The average age was 7.0 +/- 4.2 years in children and 36.0 +/- 18.0 years in adults, which demonstrates a bimodal distribution. Adults were significantly more likely than children to present with a complaint other than mass or infection (P < .01), including pain, dysphagia, dysphonia, and fistula formation. There was no significant difference in frequency of location between the adults and children. In this article, 94.9% (56/59) of the adults and 87.
