Prostate Cancer Precise Detection and Staging Insight by Dr Benji Benjamin

PSMA is an enzyme found in abundance on the cell surface of prostate cancer cells. Until recently patients newly diagnosed with high risk prostate cancer or patients where the prostate cancer has returned or metastasised would generally undergo a range of scans such as CT, bone and MRI to detect and stage prostate cancer.

Physical Activity and Cancer Risk

New studies are exploring the role of physical activity in cancer survivorship and quality of life, cancer risk, and the needs of populations at increased risk... Read on to find the links between physical activity and cancer

 

Dietary Fibre and Prostate Cancer Risk

Dietary Total and Insoluble Fiber Intakes Are Inversely Associated with Prostate Cancer Risk" according to a new study published in the Journal of Nutrition.

 

An Approach to Prostate Segmentation on MR Images

Prostate segmentation on MR images attracted greater research interest in recent years, with the introduction of conformal radiotherapy (CRT) and intensity modulated radiotherapy (IMRT) for prostate cancer. Accurate delineation of tumor target volume and organs at risk becomes increasingly important in radiotherapy treatment planning. However, it is difficult to perform fully automated segmentation in T2-weighted images because the signal intensity within the prostate is inhomogeneous as it reflects the underlying characteristics of the glandular tissue [1]. The interface between the prostate and the rectum and bladder is not always clear.

 

Current Role and Future Perspectives of Magnetic Resonance Spectroscopy

Further to the development of three-dimensional (3D) conformal, intensity-modulated, image-guided, adaptive radiation therapy, major changes have occurred in the last three decades in the treatment planning of nonmetastatic prostate cancer. These techniques have significantly improved treatment precision, allowing for greater sparing of critical organ and delivery of escalated doses of radiation to the target volume.

 

Quality assessment for VMAT prostate radiotherapy planning based on data envelopment analysis

During the past two decades, radiotherapy treatment techniques have advanced significantly due to the development of dynamic multileaf collimators coupled with commercially available inverse planning systems. This has led to the widespread use of intensity modulated radiation therapy (IMRT) which facilitates improved conformance to the treatment volume while minimizing dose to surrounding avoidance structures... This research paper looks at using data envelopment analysis (DEA) to address potential inefficiencies in planning adjustment.
