Summary
This study highlights the successful treatment of unresectable intrahepatic cholangiocarcinoma (ICC) using carbon-ion radiation. Fluorodeoxyglucose-positron emission tomography (FDG-PET) proved useful in assessing tumor viability during treatment.
Area of Science:
- Oncology
- Radiology
- Nuclear Medicine
Background:
- Intrahepatic cholangiocarcinoma (ICC) is a significant primary hepatic tumor with poor prognosis due to late diagnosis and limited treatment options.
- Assessing primary tumor viability is crucial for evaluating therapeutic efficacy, yet current methods are insufficient.
Observation:
- A 31-year-old male with unresectable ICC was treated with carbon-ion radiation therapy.
- Fluorodeoxyglucose-positron emission tomography (FDG-PET) was employed to monitor the primary tumor's response.
Findings:
- The patient achieved successful treatment outcomes with carbon-ion radiation.
- FDG-PET demonstrated utility in determining the viability of the primary ICC lesion during treatment.
Implications:
- Carbon-ion radiation therapy shows promise for unresectable ICC.
- FDG-PET can be a valuable tool for assessing treatment response and tumor viability in ICC management.

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...
