<b>Background and Objective:</b> Doxorubicin is an anticancer therapy belonging to the anthracycline class, which has clinical activity in breast cancer. Doxorubicin can cause cardiotoxic effects due to the formation of doxorubicinol as its main metabolite. The purpose of this study was to obtain the optimum sample preparation conditions for the analysis of doxorubicin in VAMS and as a form of therapeutic drug monitoring (TDM) in patients with cancer breasts. <b>Materials and Methods:</b> Analyze doxorubicin and doxorubicinol levels with Volumetric Absorptive Microsampling (VAMS) in patients' cancer breasts receiving doxorubicin in their therapeutic regimen. The sample was analyzed using Ultra Performance Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS). The method uses deep linear range concentrations of 8-200 ng/mL for doxorubicin and 3-100 ng/mL for doxorubicinol. <b>Results:</b> Multiple reaction monitoring (MRM) value set at m/z 544.22>396.9 for doxorubicin; m/z 546.22>398.9 for doxorubicinol and m/z 528.5>362.95 for daunorubicin. The LLOQ value obtained was 8 ng/mL for doxorubicin and 3 ng/mL for doxorubicinol with linearity of 0.9904 for doxorubicin and 0.9902 for doxorubicinol. Analysis results show doxorubicin levels were in the range of 9.47 ng/mL to 87.84 ng/mL and doxorubicinol range between 4.24 and 54.02 ng/mL. <b>Conclusion:</b> Dosage cumulative doxorubicin ranges between 47.93 and 346.09 mg/m<sup>2</sup>; with this, the risk of cardiomyopathy in the patients surveyed is under 4%, according to the literature.
