Role PET Imaging in Response Assessment for Hepatocellular Carcinoma (HCC)

2014-08-27 03:13:58 | BioPortfolio


Present imaging modalities for primary liver cancer (hepatocellular carcinoma or HCC) have several shortcomings. One important shortcoming is the time delay between successful treatment and radiological confirmation of this response. Often it takes several months for anatomical changes to occur and to be appreciated on morphological imaging such as CT or MRI (shrinkage of tumor, absence of contrast enhancement). Functional imaging by means of Fluor-18 deoxyglucose or Fluor-18 Choline (positron emitters, PET-scan) might be an early indicator of response. This "early" information might help to tailor treatment. For instance, if no response is induced, an early switch in therapy can be planned.

The present study investigates whether the routine PET-tracer (Fluor-18 deoxyglucose) and the experimental PET-tracer, Fluor-18 Choline help to predict response if a patient with inoperable primary liver cancer is treated (radionuclide therapy, biologicals).

Medical and Biotech [MESH] Definitions

Procedures, surgery, or other treatment without consent of person or persons receiving treatment.

Extracts of liver tissue containing uncharacterized specific factors with specific activities; a soluble thermostable fraction of mammalian liver is used in the treatment of pernicious anemia.

Conditions in which the LIVER functions fall below the normal ranges. Severe hepatic insufficiency may cause LIVER FAILURE or DEATH. Treatment may include LIVER TRANSPLANTATION.

Withholding or withdrawal of a particular treatment or treatments, often (but not necessarily) life-prolonging treatment, from a patient or from a research subject as part of a research protocol. The concept is differentiated from REFUSAL TO TREAT, where the emphasis is on the health professional's or health facility's refusal to treat a patient or group of patients when the patient or the patient's representative requests treatment. Withholding of life-prolonging treatment is usually indexed only with EUTHANASIA, PASSIVE, unless the distinction between withholding and withdrawing treatment, or the issue of withholding palliative rather than curative treatment, is discussed.

A naturally occurring compound that has been of interest for its role in osmoregulation. As a drug, betaine hydrochloride has been used as a source of hydrochloric acid in the treatment of hypochlorhydria. Betaine has also been used in the treatment of liver disorders, for hyperkalemia, for homocystinuria, and for gastrointestinal disturbances.
