Why anti‑estrogen therapy fails in ovarian cancer, and how to make it work

Rákkutatás · Ovarian cancer · TP53

Mutant p53 proteins bind estrogen receptors and block estrogen signaling, driving resistance to anti‑estrogen therapy in ovarian cancer; silencing mutant p53 or using p53‑restoring drugs such as rezatapopt can resensitize tumors to hormone therapy, offering a promising combination treatment strategy.

Anti‑estrogen therapy often fails in high‑grade serous ovarian cancer because mutant p53, present in 96% of cases, disrupts estrogen receptor signaling and drives resistance. Silencing mutant p53 or using drugs like rezatapopt to restore p53 function can resensitize tumors to hormone therapy, suggesting a promising combination treatment strategy.

High‑grade serous ovarian cancer has a high relapse rate and limited effective therapies; understanding the mechanisms of endocrine resistance can improve treatment options and patient outcomes.
