Results of the SWOG S1007 RxPONDER clinical trial suggest that many postmenopausal women with early-stage hormone receptor (HR)-positive, HER2-negative breast cancer, and 1 to 3 positive axillary lymph nodes may be able to avoid adjuvant chemotherapy. By contrast, premenopausal women can derive benefit from adjuvant chemotherapy, based on findings of a prespecified interim analysis of the phase 3 RxPONDER clinical trial; the findings were presented at the 2020 San Antonio Breast Cancer Symposium.

On January 15, 2021, experts in the management of patients with cholangiocarcinoma (CCA) convened for a virtual accredited continuing education satellite symposium held during the 2021 annual meeting of the American Society of Clinical Oncology Gastrointestinal Cancers Symposium. The goal was to educate healthcare providers on various aspects of CCA, including epidemiology, current standards of care, unmet clinical needs, the safety and efficacy of fibroblast growth factor receptor (FGFR) inhibitors as second-line therapy, and practical approaches to incorporating FGFR inhibitors into the treatment paradigm for the disease.

According to the American Cancer Society, nearly 35,000 new patients with multiple myeloma are diagnosed annually in the United States, with more than 12,000 deaths attributed to this cancer. However, with the introduction of several novel therapies, the outcomes for patients with newly diagnosed multiple myeloma have improved substantially over the past decade.

Researchers have identified 2 inherited pathogenic genetic variants in patients with pediatric neuroblastoma, according to results from a study presented at the 2021 virtual American Association for Cancer Research annual meeting. Both variants—the ALK gene and loss of function in PHOX2B—are associated with worse outcomes.

Despite improvements in the treatment of advanced ovarian cancer, less than half of newly diagnosed patients survive longer than 5 years, and relapse rates remain high. At the Society of Gynecologic Oncology (SGO) 2021 Virtual Annual Meeting on Women’s Cancer, experts presented updated results from 2 phase 3 clinical trials showing the benefit of the poly (ADP-ribose) polymerase (PARP) inhibitors olaparib (Lynparza) and niraparib (Zejula) as maintenance therapy in women with advanced or recurrent disease.
