Combination Treatment and Patient Selection for Relugolix vs Leuprolide
Thematic Newsreels
Atish D. Choudhury, MD, PhD, a medical oncologist and clinical/translational investigator at the Lank Center for Genitourinary Oncology at Dana-Farber Cancer Institute, discusses current guideline recommendations for the use of relugolix and leuprolide, relugolix as a combination backbone, and important considerations when applying these data to clinical practice.

Over the past year, several important studies in ovarian cancer have been presented at multiple oncology meetings and published in a number of peer-reviewed publications. In this installment of a two-part discussion for The ASCO Post Newsreels, Ursula A. Matulonis, MD, and Joyce F. Liu, MD, MPH, discuss antibody-drug conjugates and clinical trials including PRIMA and ATHENA. In part two of this feature, Dr. Matulonis and Dr. Liu talk about low-grade serous ovarian carcinoma and an important recently published study.

Erika Hamilton, MD, Director, Breast Cancer Research at Sarah Cannon Research Institute, provides a look at “where we stand in 2025” in the field of oral selective estrogen receptor degraders (SERDs) for patients with estrogen receptor–positive, HER2-negative breast cancer. She discusses the first and only FDA-approved oral SERD, elacestrant, indicated for use after CDK4/6 inhibitor therapy in patients with ESR1 mutations; reviews agents still being tested in clinical trials, such as imlunestrant and camizestrant; and highlights the role of oral SERDs as both monotherapies and in novel combinations. As Dr. Hamilton explains, “there haven’t been novel endocrine backbones [for these patients] since fulvestrant.”

Arvind N. Dasari, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses data presented at the ESMO Gastrointestinal Cancers Congress 2025, which showed that adding circulating tumor DNA (ctDNA) testing to current standard of care surveillance for patients with colorectal cancer (CRC) better identified patients who are appropriate candidates for metastasis-directed therapy.

Atish D. Choudhury, MD, PhD, a medical oncologist and clinical/translational investigator at the Lank Center for Genitourinary Oncology at Dana-Farber Cancer Institute, discusses forms of hormonal therapy for patients with prostate cancer, with a focus on the HERO trial, which evaluated oral relugolix vs injectable leuprolide in patients with advanced hormone-sensitive disease. Dr. Choudhury touches on additional analyses from HERO as well, including the effects seen with relugolix on major cardiovascular events.

Raajit K. Rampal, MD, PhD, Director of the Center for Hematologic Malignancies and the Myeloproliferative Neoplasms Program at Memorial Sloan Kettering Cancer Center, reviews the four FDA-approved Janus kinase (JAK) inhibitors for patients with myelofibrosis, touching upon differences in their mechanisms of action and toxicity profiles. He also discusses clinical trials of add-on drugs to the currently approved JAK inhibitors, which may increase their efficacy and durability, as well as trials of novel JAK inhibitors and immunotherapies targeting CALR.
