Castration-resistant prostate cancer

Castration-resistant prostate cancer is an advanced, biologically aggressive malignancy of the male genitourinary system characterized by disease progression despite medical or surgical castration Pathophysiologically, the tumor circumvents systemic androgen deprivation through mechanisms such as androgen receptor amplification, mutations, or alternative signaling cascades that sustain tumor cell proliferation in an androgen-depleted environment It is clinically defined by objective radiographic...

Pathophysiologically, the tumor circumvents systemic androgen deprivation through mechanisms such as androgen receptor amplification, mutations, or alternative signaling cascades that sustain tumor cell proliferation in an androgen-depleted environment

It is clinically defined by objective radiographic progression or serial increases in serum prostate-specific antigen levels occurring in the presence of castrate serum testosterone levels below 50 ng/dL The condition encompasses both non-metastatic and metastatic stages, commonly spreading to regional lymph nodes, visceral organs, and bone
