Is there a standard frequency for lurbinectedin side effect surveillance?

How often should patients on lurbinectedin get blood work to track side effects?
Routine monitoring starts with a complete blood count before every 21-day cycle. Counts are checked again on day 8 and day 15 if neutropenia occurs in the prior cycle. Liver-function tests repeat at the same intervals whenever baseline values are abnormal.

What blood counts trigger a dose delay or reduction?
Treatment is held if the absolute neutrophil count falls below 500 cells/mm³ or platelets drop below 50,000/mm³. Permanent dose reduction follows the second occurrence of grade-3 or -4 neutropenia or thrombocytopenia.

How long do side-effect checks continue after the last dose?
Weekly blood counts are recommended for at least four weeks after discontinuation because late-onset myelosuppression has been observed.

Are extra scans needed to watch for lung or heart toxicity?
No routine imaging schedule is mandated beyond standard disease assessments. Cardiac monitoring with ECG is advised only if symptoms appear or if patients have pre-existing cardiac disease.

Who sets the exact monitoring schedule?
Each prescriber follows the FDA label but may add visits or labs based on patient-specific risk factors.
