Lower risk of COVID 19 in prostate cancer patients treated with hormone therapy: study

Men whose prostate cancer was treated with androgen-deprivation therapy (ADT) had a significantly lower risk of COVID-19 infection, according to a large retrospective study of Italian patients published in Annals of Oncology.

Cell entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) depends on the binding of the viral spike (S) proteins to angiotensin-converting enzyme 2 and S protein priming by TMPRSS2. Inhibition of TMPRSS2 may work to block or decrease the severity of SARS-CoV-2 infections. Intriguingly, TMPRSS2 is an androgen-regulated gene that is up-regulated in prostate cancer where it supports tumor progression and is involved in a frequent genetic translocation with the ERG gene. First- or second-generation androgen-deprivation therapies (ADTs) decrease the levels of TMPRSS2.

M. Montopoli et. al. attached to the Department of Pharmaceutical and Pharmacological Sciences, Padova, Italy, carried out the study to find out whether androgen deprivation therapies (ADTs) may protect patients affected by prostate cancer from SARS-CoV-2 infections.

The study design consisted of data extracted from 9280 patients (4532 males) with laboratory-confirmed SARS-CoV2 infection from 68 hospitals in Veneto, one of the Italian regions that were most affected by the coronavirus disease 2019 (COVID-19) pandemic.
