CLINICAL STUDIES ON TUMOR MARKERS IN PROSTATE CANCER

The Role of radiobiological parameters on Tumor control probability (TCP) in prostate cancer

Introduction: The aim of this study was to evaluation radiobiological modeling parameters on tumor control probability (TCP) for prostate cancer in three different models. These parameters included α⁄β ratios and cell surviving fraction at 2 Gy (SF2). Materials and Methods: The Poisson, equivalent uniform dose (EUD) and linear quadratic (LQ) models was used as...

Tumoral Markers in Prostate Cancer

In Mexico, in 70% of cases, the prostate cancer (PCa) is found in advanced stage. PCa currently occupies second place in frequency of cancer in men, surpassed only by skin cancer, and is the second principal cause of death in men after of lung cancer (Hall et al., 2005). Reactive oxygen species (ROS) such as superoxide (O2 −) and hydrogen peroxide (H2O2) are found in a large number of tumors a...

Tumor markers in breast cancer--evaluation of their clinical usefulness.

Breast cancer is the most common neoplasm affecting women in the Western world. Many studies are still conducted with the purpose of finding markers that could be used for early diagnosis and/or serve as possible reliable prognostic or predictive parameters, but with conflicting results. At present, no markers are available for an early diagnosis of breast cancer For surveillance of patients wi...

Tumor markers in clinical oncology

The subtle differences between normal and tumor cells are exploited in the detection and treatment of cancer. These differences are designated as tumor markers and can be either qualitative or quantitative in their nature. That means that both the structures that are produced by tumor cells as well as the structures that are produced in excessive amounts by host tissues under the influence of t...
