PET/CT predicts early breast cancer response to chemo
By using FDG-PET/CT, physicians will be in a better position to noninvasively predict a breast cancer patient's response to treatment after two cycles of neoadjuvant chemotherapy, helping them decide on the next course of action, concluded a study from Germany.

FLT-PET could help predict outcome in head and neck cancer
Change in F-18 fluorothymidine (FLT) uptake on PET during early radiotherapy or chemoradiotherapy is a strong indicator of the long-term outcomes of head and neck cancer patients, Dutch researchers report in the April issue of the Journal of Nuclear Medicine.
