Interstitial pneumonitis associated with leuprorelin acetate for a prostate cancer: A case report.

Introduction: Androgen deprivation therapy remains the essential treatment for disseminated prostate cancer. Interstitial pneumonitis following this therapy has been documented for just a few cases. However, reported cases frequently describe the onset of symptoms after recent administration (days or a few weeks) of both GnRH analogues and androgen antagonists, which makes the precise individual impact of each treatment difficult to estimate.

[Aggressive variants of castration resistant prostate cancer (CRPC): neuroendocrine prostate cancer.].

Castration resistant prostate cancer (CRPC) is characterized by an important molecular, pathological and clinical heterogeneity. Although most of them present androgen receptor (AR) signal dependence, there are independent phenotypes. Neuroendocrine prostate cancer (NEPC) is a rare histologic subtype with adverse prognosis due to late diagnosis, heterogeneous clinical features and lack of effective systemic treatments.
