Survivin, a member of the inhibitor of apoptosis (IAP) protein family that inhibits caspases and blocks cell death, is highly expressed in most cancers and is associated with a poor clinical outcome. Survivin has consistently been identified by molecular profiling analysis to be associated with high tumour grade cancers, different disease survival and recurrence. Polymorphisms in the survivin gene are emerging as powerful tools to study the biology of the disease and have the potential to be used in disease prognosis and diagnosis. The survivin gene polymorphisms have also been reported to influence tumour aggressiveness as well as survival of cancer patients. The differential expression of survivin in cancer cells compared to normal tissues and its role as a nodal protein in a number of cellular pathways make it a high target for different therapeutics. This review discusses the complex circuitry of survivin in human cancers and gene variants of survivin, and highlights novel therapy that targets this important protein.

Urinary bladder cancer is a major epidemiological problem that continues to grow each year. It opens avenues for investigative research for the identification of new disease markers and diagnostic techniques. In this pilot study, utility of non-invasive (1)H NMR spectroscopy has been evaluated for probing the metabolic perturbations occurring in non-muscle invasive urinary bladder cancer. (1)H NMR spectra of urine of bladder cancer patients and controls (healthy and urinary tract infection/bladder stone) (n = 103) were acquired at 400MHz. The non-overlapping resonances of citrate, dimethylamine, phenylalanine, taurine and hippurate were first identified and then quantitated by (1)H NMR spectra, with respect to an external reference sodium-3-trimethylsilylpropionate (TSP). The concentrations of these metabolites were then statistically analyzed. The cancer patients showed significant (p < 0.05) variations in concentration of hippurate and citrate as compared with healthy controls and benign controls. The significant elevation in concentration of taurine was observed in urine of bladder cancer patients, which was below the sensitivity limit of 400MHz in control cases. However, stages Ta, T1 and carcinoma in situ (CIS) cannot be differentiated on the basis of altered metabolite indices but their composition may reflect the biochemical alterations in metabolism of cancer cells.

Neither Contigen nor Durasphere provides durable improvement in continence. Despite this outcome a third of patients in the 2 groups were satisfied with the treatment outcome.

This large study, which expands the scant existing literature on uroflow parameters in healthy children, will hopefully promote wider application of uroflowmetry testing in the pediatric population.
