The sequencing of the human genome has opened the door for proteomics by providing a sequence-based framework for mining proteomes. As a result, there is intense interest in applying proteomics to foster a better understanding of cancer processes, develop new biomarkers for diagnosis and early detection of cancer. Gastric carcinoma is one of the most common malignancies worldwide and is the most common cause of cancer-related death in China. The main barrier for improving survival rate is short of useful marker for early diagnosis.

The determination of the precise anatomical location of a tumor is the prerequisite for setting optimal parameters for radiation treatment of prostate cancer. This approach guarantees that the ionizing radiation only destroys tumorous cells and does not affect other organs in the vicinity of the prostate.

In a cooperative study with Innsbruck Medical University and the East-Vienna Center of Social Medicine, two physicists of Vienna University of Technology (TU), evaluated the mean deviation of radiation parameters for prostate cancers and compared various sources of radiation.
