Describing Prostate Cancer Dynamics: Second Look at PSA-Doubling Time and PSA-Specific Growth Rate

Physicians responsible for patient care focus on readily available clinical and trending labo‐ ratory data to help direct the patient’s clinical course and evaluate efficacy of therapy. Most clinicians fail to incorporate newer parameters of tumor response such as tumor growth rate when evaluating patient treatment response. Available now, is a wealth of dynamic growth parameters that shed new ...

Molecular dynamics studies of straight-chain alkanes diffusion in SiO2 ceramic versus Bosanquet formula

Molecular Dynamics (MD) simulations were applied to calculate self-diffusion coefficients (Di ) and heats of adsorption for ethane, propane and n-butane. The simulations were done in temperature range of 300-525 K for various concentrations inside the pores of silicalite type zeolite. The calculated values of self-diffusion coefficients and heats of adsorption resulted from the current wo...

Experiences of Uncertainty in Men With an Elevated PSA.

A significant proportion of men, ages 50 to 70 years, have, and continue to receive prostate specific antigen (PSA) tests to screen for prostate cancer (PCa). Approximately 70% of men with an elevated PSA level will not subsequently be diagnosed with PCa. Semistructured interviews were conducted with 13 men with an elevated PSA level who had not been diagnosed with PCa. Uncertainty was prominen...

What to do with an abnormal PSA test.

For more than a decade, prostate-specific antigen (PSA) has been used for prostate cancer screening. Over the years, this screening has been continually refined, including investigation into the use of lower total PSA thresholds, PSA isoforms, and PSA kinetics. This review describes the evolution of prostate cancer screening and provides clinical insights into the informed use of PSA and its ad...
