Stereotactic Radiotherapy (SRT) Liver
Summary
A minority of patients with colorectal liver metastases and hepatobiliary cancer (primary liver cancer) are candidates for surgery, but there are no curative treatment options for these patients. Their median survival time is 3 to 12 months. Stereotactic radiation (SRT) (highly conformal radiotherapy (CRT)) is a treatment option for these patients with unresectable liver cancer, now possible due to improvements in our ability to localize and immobilize liver tumors and an improved understanding of the partial liver volume tolerance to radiation. SRT should permit liver tumors to be treated to tumorcidal doses while sparing the uninvolved liver, decreasing the risk of treatment related normal tissue toxicity. With such conformal radiation, it is possible to deliver radiation in fewer fractions than traditionally required, which should be more convenient for patients. In this study, CRT will be delivered during shallow breathing or breath hold to minimize organ motion due to breathing, decreasing the volume of normal liver that must be irradiated.

Medical and Biotech [MESH] Definitions
Radiotherapy, Intensity-modulated
CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions.
Radiotherapy, Conformal
Radiotherapy where there is improved dose homogeneity within the tumor and reduced dosage to uninvolved structures. The precise shaping of dose distribution is achieved via the use of computer-controlled multileaf collimators.
Neoplasms By Site
A collective term for precoordinated organ/neoplasm headings locating neoplasms by organ, as BRAIN NEOPLASMS; DUODENAL NEOPLASMS; LIVER NEOPLASMS; etc.
Radiotherapy, Adjuvant
Radiotherapy given to augment some other form of treatment such as surgery or chemotherapy. Adjuvant radiotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Radiotherapy
The use of IONIZING RADIATION to treat malignant NEOPLASMS and some benign conditions.
