Pegylated Liposomal Doxorubicin-Induced Acute Transient Encephalopathy in a Patient with Breast Cancer: A Case Report
نویسندگان
چکیده
BACKGROUND Pegylated liposomal doxorubicin (PLD) has a unique pharmacokinetic profile and is widely used to treat a variety of malignancies, alone or in combination with other agents. CASE REPORT A 57-year-old female patient with metastatic breast cancer developed dural metastases to the brain and underwent craniotomy and whole-brain radiation. She continued to receive chemotherapy with carboplatin without any serious complications. Four months later, there was evidence of progression leading to the institution of PLD. During the first course of PLD, there was evidence of acute encephalopathy which resolved after 18 h with discontinuation of this agent. Interestingly, she did well when she was rechallenged with conventional doxorubicin in the following cycles. CONCLUSION We hereby report, to the best of our knowledge, the first case of acute transient encephalopathy induced by PLD. We postulate that partial disruption of the blood-brain barrier may have been responsible for PLD-induced encephalopathy.

AIMS AND BACKGROUND Anthracyclines such as doxorubicin play a central role in the management of advanced breast cancer. Unfortunately, the clinical benefits of anthracyclines are limited by cardiotoxicity that can lead to the development of potentially fatal congestive heart failure. In order to limit anthracycline-related cardiotoxicity, liposomal formulations of doxorubicin have been develope...

also called hand-foot syndrome (HFS), is a distinctive and relatively frequent dermatological toxic reaction associated with certain chemotherapeutic agents: pegylated liposomal doxorubicin, cape citabine, a long-circulating formulation of doxorubicin, cytosine arabinoside, interleukin 2. HFS typically presents with dysaesthesia and tingling in the hands and feet. Dysaesthesias and erythema may...

PURPOSE Chemotherapy regimens containing anthracyclines and taxanes represent the landmark of neoadjuvant systemic therapy of breast cancer. In advanced breast cancer patients liposomal anthracyclines (LA) have shown similar efficacy and less cardiac toxicity when compared to conventional anthracyclines. We performed this retrospective analysis in order to evaluate the efficacy and tolerability...
متن کاملNew approaches in the management of advanced breast cancer - role of combination treatment with liposomal doxorubicin.
Metastatic breast cancer (MBC) remains a major cause of morbidity and mortality in women worldwide. For three decades doxorubicin, alone or in combination with other cytotoxic agents, has been a mainstay of systemic therapy for MBC. However, its use is limited by cumulative cardiotoxicity. More recently liposomal formulations of doxorubicin have been developed which exhibit equal efficacy but r...
