The effect of neoadjuvant androgen deprivation therapy on tumour hypoxia in high-grade prostate cancer: a 18F-MISO PET/MRI imaging study.

Tumour hypoxia is associated to treatment resistance. In this prospective study of 11 patients, we evaluated the occurrence of hypoxia in high-grade prostate cancer by multiparametric integrated18F-MISO PET/MRI before and after 3 months of androgen deprivation. Our results show the presence of hypoxic conditions in prostate carcinoma, correlated with tumour grade and responding to androgen ablation, thus supporting the re-oxygenation role of a neoadjuvant androgen deprivation therapy phase in combination with curative radiotherapy.
