Resumen
Antecedentes y objetivo

En Perú se realiza la presentación de trastuzumab en presentación endovenosa (TZM-IV) y trastuzumab en presentación subcutánea (TZM-SC). Pero no hay datos de costos comparativos por vía de administración. El objetivo de nuestro estudio fue conocer los costos de las pacientes con cáncer de mama, comparando las vías de administración en un centro oncológico regional del Perú.

Material y métodos

En 2020 a los pacientes que se pautó tratamiento con trastuzumab (TZM) de manera prospectiva se registraron los datos clínicos, demográficos y de transporte, y se obtuvieron los costos médicos de los expedientes de historia médica y farmacia. Con estos datos se realizó la simulación a 100 pacientes que recibieron 18 ciclos del fármaco.

Resultados

El principal contribuyente al costo de la diferencia fue el costo del medicamento en sí, siendo S/. 4.711,11 (1.323,35 USD) y S/. 4.680,30 (1.314,69 USD) para TZM-IV y TZM-SC, respectivamente. Los costos de administración para tratar a 100 pacientes con ciclos completos de TZM-IV y TZM-SC fueron S/. 334.488,53 (93.957,45 USD) y S/. 207.455,33 (58.873,97 USD), respectivamente. Los costos indirectos indican que los pacientes perdieron en total, S/. 1.123,28 (315,53 USD) y S /. 1.148,60 (322,64 USD) en TZM-IV y TZM-SC por paciente, respectivamente.

Conclusiones

Se recomienda el uso de TZM-SC, en el escenario de un menor costo del medicamento y menor duración del tiempo de administración. Sobre todo, en un país con bajo financiamiento, que solo permite subsidiar los costos directos del tratamiento del cáncer.

Abstract
Antecedent and objective

In Peru, the presentation of TZM-IV and TZM-SC is carried out. But there is no comparative cost data by route of administration. The objective of our study was to know the costs of patients with breast cancer, comparing the routes of administration in a regional cancer center in Peru.

Material and methods

In 2020, patients who were prescribed TZM treatment were prospectively recorded clinical, demographic and transport data, and medical costs were obtained from medical history and pharmacy records. With these data, the simulation was performed in 100 patients who received 18 cycles of the drug.

Results

The main contributor to the cost of the difference was the cost of the drug itself, being S/. 4,711.11 (1,323.35 USD) and S/. 4,680.30 (1,314.69 USD) for TZM-IV and TZM-SC, respectively. The administration costs to treat 100 patients with complete cycles of TZM-IV and TZM-SC were S/. 334,488.53 (93,957.45 USD) and S/.207,455.33 (58,873.97 USD), respectively. Indirect costs indicate that patients lost in total, S/. 1,123.28 (315.53 USD) and S/. 1,148.60 (322.64 USD) in TZM-IV and TZMSC per patient, respectively.

Conclusions

The use of TZM-SC is recommended, in the scenario of a lower cost of the drug and a shorter duration of administration time. Especially in a country with low funding, which only allows subsidizing the direct costs of cancer treatment.
