What are the possible side effects of Trabectedin?

Although Trabectedin has shown unique efficacy in the treatment of soft tissue sarcoma, as an anti-tumor drug, it can also cause certain side effects. The manifestations of side effects vary from individual to individual, and the severity is closely related to the dosage, duration of treatment, and the patient's overall health condition.

One of the most common adverse reactions is hematological toxicity. Because trabectedin inhibits bone marrow hematopoietic function, some patients may experience leukopenia, anemia, or thrombocytopenia. These changes may increase the risk of infection, bleeding, and fatigue, so clinical practice usually monitors blood levels after each course of treatment so that medication can be adjusted in a timely manner.

Abnormal liver function is also an important side effect of trabectedin. Some patients will experience elevated transaminases or abnormal bilirubin levels during treatment, which is related to drug metabolism and excretion in the liver. Although in most cases these indicators can recover after stopping the drug or reducing the dosage, in severe cases they may affect the continuation of treatment, so close monitoring is required.

In addition to hematological and liver toxicity, patients may also experience gastrointestinal reactions such as nausea, vomiting, fatigue, and decreased appetite. Although these symptoms are not necessarily life-threatening, they can affect the patient's quality of life, so treatment is often supplemented with antiemetic drugs and supportive care. Some patients also reported muscle pain or body aches, suggesting that the drug may also have some effect on muscle tissue.

In rare cases, trabectedin may also cause serious adverse events, such as rhabdomyolysis, serious infection, or acute liver injury. Although the incidence rate is low, once it occurs, the medication needs to be stopped immediately and actively treated. It's important to note that not all patients experience the same side effects, and some tolerate the entire course of treatment with only mild discomfort.
