Utilidad de la gammagrafía mamaria en la valoración de la respuesta a la quimioterapia neoadyuvante en el cáncer de mama

Breast scintigraphy with Tc-99m-sestamibi is not useful in predicting the response to neoadjuvant chemotherapy in breast cancer. Traditional physical examination and mammography are more effective. Isotope uptake and clearance do not predict response and there is not an effective in vivo measurement of chemo-resistance or tumor angiogenesis.
