Epigenome-wide analysis reveals potential biomarkers for radiation-induced toxicity risk in prostate cancer.

Background: Prostate cancer is the second most common cancer globally, with radiation therapy (RT) being a key treatment for clinically localized and locally advanced cases. Given high survival rates, addressing long-term side effects of RT is crucial for preserving quality-of-life. Radiogenomics, the study of genetic variations affecting response to radiation, has primarily focussed on genomic biomarkers, while DNA methylation studies offer insights into RT responses.

How Imaging Advances Are Defining the Future of Precision Radiation Therapy.

Radiation therapy is fundamental in the treatment of cancer. Imaging has always played a central role in radiation oncology. Integrating imaging technology into irradiation devices has increased the precision and accuracy of dose delivery and decreased the toxic effects of the treatment.

Advanced imaging of colorectal cancer: From anatomy to molecular imaging.

Unlabelled: Imaging techniques play a key role in the management of patients with colorectal cancer. The introduction of new advanced anatomical, functional, and molecular imaging techniques may improve the assessment of diagnosis, prognosis, planning therapy, and assessment of response to treatment of these patients. Functional and molecular imaging techniques in clinical practice may allow the assessment of tumour-specific characteristics and tumour heterogeneity.

[Quality of life after biochemical recurrence in patients with prostate cancer. How and how long do patients live after biochemical recurrence?].

Routine monitoring of PSA in patients with localized prostate cancer radically treated permits to identify those with biochemical recurrence only. Treatment options for biochemical failure include observation, surgery, radiotherapy alone or combined with hormonal therapy, brachytherapy, cryotherapy and hormone therapy exclusively. These treatments determine a specific pattern of changes (urinary function, bowel, sexual and hormonal) that can negatively impact the quality of life, so that the indication must be made in a judicious way and always in consonance with patient's expectations and preferences.
