25 Real-world BRCA1/2 Testing Patterns in HER2–Negative Early- Stage Breast Cancer (eBC) Patients

Disorders of Sex Development and Malignant Germ Cell Tumors

Key points: Patients with disorders of sex development (DSDs) are at an increased risk of malignant germ cell tumors (GCTs). In adulthood, the partial form of androgen insensitivity syndrome confers the greatest risk of developing malignant GCTs. Gonadoblastoma is the most common gonadal GCT arising in patients with DSDs. Despite being a benign neoplasm, it can undergo malignant transformation in up to 60% of patients with a DSD. Oncologic treatment in patients with disorders of sex development and malignant GCTs does not differ from the standard treatment for testicular GCTs. Treatment of patients with DSDs requires a multidisciplinary team, including a psychiatric, genetic, and reproductive assessment as well as the involvement of an ethics committee. An early diagnosis of DSDs is crucial to avoid the development of potentially serious complications in adulthood.

Outcomes of haploidentical vs. mismatched unrelated donor HCT with posttransplant cyclophosphamide prophylaxis

Researchers have determined that donor age has a stronger, nonlinear impact on OS vs donor type in allogeneic HCT using posttransplant cyclophosphamide for GVHD prophylaxis, with donor type becoming increasingly relevant in older donors.

Comparing GOZILA and COLOMATE: Ongoing Umbrella/Basket Trials Examining Genetic Testing in Gastrointestinal Malignancies

Circulating tumor DNA (ctDNA)-based next- generation sequencing (NGS) assays have advantages over classic tissue-based analyses because of their low invasiveness and availability of repeated sampling. The existence of various companion trials for common alterations that can be potential therapy targets on the 2 platforms can lead to future international collaboration.

Oncology Clinical Trials During the COVID-19 Pandemic

ABSTRACT The coronavirus disease 2019 (COVID-19) pandemic has rapidly spread all over the world in the past several months. No effective treatment for COVID-19 has been established. High transmissibility and considerable mortality rates have forced many national governments to implement quarantine measures. Many patients with cancer rely on clinical trials to receive their oncologic care, but the routine conduct of clinical trials has substantially changed because of the COVID-19 pandemic. The oncology research community should implement formal policies based on the guidance given from regulatory agencies, with the goal of minimizing the risks of COVID-19 infection while maintaining appropriate oncologic treatments for patients during this pandemic.
