Ovarian Cancer 2024: Year at a Glance, Part 1
Thematic Newsreels
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.

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.

Jennifer Gile, MD, of Willamette Valley Cancer Institute, talks about the first positive phase III trials in the high-risk diffuse large B-cell lymphoma (DLBCL) space—POLARIX and frontMIND. POLARIX established the superiority of a modified regimen of rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) called pola-R-CHP, in which vincristine was replaced with polatuzumab vedotin, over standard R-CHOP; frontMIND showed that the addition of the CD19 monoclonal antibody tafasitamab plus the immunomodulatory drug lenalidomide to R-CHOP also improved outcomes over standard R-CHOP. Dr. Gile discusses current considerations when choosing between these regimens and how future research may lead to even more refined patient selection.

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.

Benjamin P. Levy, MD, of Johns Hopkins Sidney Kimmel Cancer Center, discusses research into moving KRAS G12C inhibitors from the second to the first line, as well as combining them with immunotherapies and EGFR antibodies. Some potential combinations under investigation include KRAS G12C inhibitors (such as olomorasib, fulzerasib, divarasib, and adagrasib) and single-agent immunotherapy (pembrolizumab) or EGFR-targeting therapies (cetuximab).
Benjamin P. Levy, MD, of Johns Hopkins Sidney Kimmel Cancer Center, reviews currently available therapies for patients with KRAS G12C–mutated non–small cell lung cancer (NSCLC), noting the importance of genomic testing to identify individuals eligible for treatment with these agents. He discusses the two FDA-approved second-line drugs in this space—sotorasib and adagrasib—touching on their efficacy and associated adverse events. He also mentions divarasib, an investigational next-generation KRAS G12C inhibitor, which showed superiority over both sotorasib and adagrasib in a recent head-to-head phase III trial.
