Current non-invasive approaches for detection of urothelial cancers are suboptimal. We developed a test to detect urothelial neoplasms using DNA recovered from cells shed into urine. UroSEEK incorporates massive parallel sequencing assays for mutations in 11 genes and copy number changes on 39 chromosome arms. In 570 patients at risk for bladder cancer (BC), UroSEEK was positive in 83% of those who developed BC. Combined with cytology, UroSEEK detected 95% of patients who developed BC. Of 56 patients with upper tract urothelial cancer, 75% tested positive by UroSEEK, including 79% of those with non-invasive tumors. UroSEEK detected genetic abnormalities in 68% of urines obtained from BC patients under surveillance who demonstrated clinical evidence of recurrence. The advantages of UroSEEK over cytology were evident in low-grade BCs; UroSEEK detected 67% of cases whereas cytology detected none. These results establish the foundation for a new non-invasive approach for detection of urothelial cancer.

Simultaneous detection of malignancy in the endometrium and ovary represents an uncommon event. The objective of the study was to clarify the possible factors that influenced on the survival. From 1977 to 2005, totally 27 patients fulfilled the criteria and were included in the study. The medical records and the pathologic reports were reviewed. The histologic determination was followed by the World Health Organization Committee classification, and cancer stage was based on the staging system of the FIGO. The KaplanMeier survival analyses were generated and compared by the log-rank test. The incidence of synchronous primary endometrial and ovarian cancers was 3.3% in patients with endometrial cancer and 2.7% in patients with ovarian cancer. The mean survival in the group of similar histology (n ¼ 15) was 63 months, and 48 months in the group of dissimilar histology (n ¼ 12) (P ¼ 0.63). The mean survival in the group of early stage (n ¼ 21) was 68 months and 15 months in the group of advanced stage (n ¼ 6) with statistic significance (P ¼ 0.0003). However, the impact of adjuvant therapy on survival did not reach statistic significance (P ¼ 0.15 for chemotherapy; P ¼ 0.69 for radiotherapy). We conclude that the majority of the patients belonged to concordant endometrioid histology in endometrium and ovary, and it tends to be early stage and low grade with favorable prognosis. The stage had more significant influence on the survival than the histology. Adjuvant therapy should be given especially in patients with advanced stage although the optimal management remained to be determined.

In ESRD patients on long-term HD, single nucleotide polymorphisms in the promoter region of the proinflammatory cytokines IL-6 and TNF-alpha, and the regulatory monokine IL-10, show a strong association with indices of comorbidity and function, and biological and nutritional markers.

The incorporation of CCM into cytotoxic therapies may be a promising strategy for the treatment of AIPC.
