INTRODUCTION: Prostate cancer is the second most common cancer in men
worldwide and the sixth leading cause of male cancer death. Radiation therapy (external
beam or brachytherapy), radical prostatectomy and active surveillance (in selected cases)
are standard treatment options for localized prostate cancer. Long-term outcomes with
recent external beam RT techniques that use high radiation doses and conformal treatment
planning as well as neoadjuvant androgen deprivation therapy for higher-risk disease
appear similar to surgery. 3D-conformal techniques and intensity modulated RT (IMRT)
are the contemporary standard of care to treat localized prostate cancer. Conformal
techniques allow higher doses to the target, while minimizing radiation to normal tissues.
This permits a decrease in toxicity and improvement in therapeutic index.

INTRODUCTION: Intensity-modulated radiation therapy (IMRT) is the
standard technique for definitive radiation therapy for nasopharyngeal cancer
(NPC). In addition to thorough physical examination, adequate imaging
studies should be obtained for diagnosis, staging, and planning. Unless
contraindicated, all patients should undergo MRI of the nasopharynx and
neck, preferably 3-mm slice thickness. A PET/CT scan is also preferable.
However, including the PET-avid region only as gross tumor volume (GTV)
is inadequate. The skull base, i.e., clivus, and the nerves are best seen on
MRI. Marrow infiltration of disease is best seen on T1-weighted noncontrast
MRI sequence. Fusion of the skull base portion of the MRI will aid in the
delineation of the GTV. CT simulation with IV contrast should be performed
to help guide the GTV target, particularly for the lymph nodes.

the shoulders will be preferable to only immobilizing the head and neck
