Capecitabine

Last Update: January 15, 2017.

OVERVIEW

Introduction

Capecitabine is a pyrimidine analogue used as an antineoplastic agent to treat metastatic and advanced forms of breast and colon cancer, often in combination with other agents. Capecitabine is associated with a low rate of transient serum aminotransferase elevations during therapy but has been only rarely implicated in cases of clinically apparent acute liver injury.

Background

Capecitabine (kap" e sye' ta been) is a pyrimidine analogue (pentyloxycarbonyl-deoxy-fluorocytidine) that has antineoplastic action against several solid tumors, including breast and colon cancers. Capecitabine is a prodrug of 5-fluorouracil (5-FU) and is converted to this active metabolite intracellularly, where it acts by interfering with DNA, RNA and protein synthesis and inhibiting cell division. Unlike 5-FU, capecitabine can be given by mouth. Furthermore, capecitabine is converted to 5-FU in a three step process, the first of which takes place in the liver and the last two predominantly in tumor cells, which may account for why it is better tolerated than 5-FU. Capecitabine was approved for use as an anticancer agent in the United States in 1998 and is currently an important component of several cancer chemotherapeutic regimens. Current indications include advanced, metastatic breast cancer and colorectal cancers, usually after failure of first line therapies. Capecitabine is available as tablets of 150 and 500 mg generically and under the brand name Xeloda. The recommended dose is based upon body surface area and renal function, but is generally initiated in a dose of 2.5 grams per meter squared in two divided doses daily for 2 weeks, followed by a 1 week rest period and then repeated at irregular intervals in 3 week cycles. Common side effects include bone marrow suppression, diarrhea, nausea, vomiting, hand-foot syndrome, fatigue, weakness, headache, dizziness, insomnia, paresthesias, abdominal pain, stomatitis, and rash.

Hepatotoxicity

Serum aminotransferase elevations occur in a proportion of patients on conventional doses of capecitabine therapy, but elevations above 5 times the upper limit of normal are uncommon, occurring in <1% of patients. Mild serum bilirubin elevations are also common during capecitabine therapy, occurring in up to 40% of patients. The bilirubin elevations, however, are largely in the indirect (unconjugated) fraction and are usually isolated (without other liver test abnormalities), self-limited and mild. There have been no individual published case reports of clinically apparent liver injury attributed to capecitabine, but single instances of cholestatic hepatitis have been reported in clinical trials and are mentioned in the product label. The clinical features of the liver injury, such as the latency to onset, pattern of serum enzyme elevations, presence of immunoallergic or autoimmune features and typical course and outcome have not been well defined. In some reports, the serum enzyme elevations were accompanied by steatosis and inflammation which resolved when chemotherapy was discontinued.

Likelihood score: E* (Unproven but suspected cause of clinically apparent liver injury).

Mechanism of Injury

While hepatotoxicity from capecitabine may be rare, it is likely due to direct hepatotoxicity. Capecitabine is extensively metabolized in the liver via the microsomal enzyme system (predominantly 2C9), and production of a toxic or immunogenic intermediate may trigger liver injury. Capecitabine is susceptible to drug-drug interactions with anticoagulants and anticonvulsants.

Outcome and Management

The severity of the liver injury linked to capecitabine therapy is generally mild. Capecitabine has not been linked to cases of acute liver failure, chronic hepatitis or vanishing bile duct syndrome. There is no information on cross sensitivity to hepatic injury between capecitabine and 5-FU or other pyrimidine analogues.
