The poster presented by Dr. Haley M. Meyer et al., from Mayo Clinic Arizona is titled "Lurbinectedin in Prostatic Small Cell and Neuroendocrine Carcinoma". SC/NEPC is a high-grade, invasive malignancy that is distinct to Prostatic Adenocarcinoma and behaves similarly to Small Cell Lung Cancer (SCLC), and treatments in second-line and beyond are major clinical challenges. This study was carried out in four academic centers of eighteen highly pretreated metastatic patients with a median number of four prior systemic therapies administered before lurbinectedin. Clinical Benefit Rate was found in 56.3%, with Partial Response in 5 of 16 patients, 31%. The study concluded that lurbinectedin is a well-tolerated and active treatment option for patients with SC/NEPC.
Dr. Alan H. Bryce, M.D., C.P.E., Chief Clinical Officer of City of Hope Cancer Center, Phoenix, commented "the Partial Response rate of 31% and Stable Disease in an additional 25% is quite promising in this highly refractory disease population". Dr. Mohammad Jad Moussa from The University of Texas, MD Anderson Cancer Center, Houston, Texas, presented the poster "Clinical efficacy of lurbinectedin in Metastatic Neuroendocrine Carcinomas of the genitourinary tract: Multi-institutional real-world experience." Neuroendocrine Carcinomas (NEC) of the genitourinary (GU) tract, including Small Cell (SC) metastasic NEC (mNEC) and Large Cell (LC) NEC, are rare aggressive malignancies. The investigator reports the first multi-institutional data with fourteen patients treated with lurbinectedin in GU mNEC with encouraging responses close to those seen in SCLC, in previously treated bladder mNEC. Larger cohorts are needed to confirm the survival benefit and genetic analyses are warranted to identify characteristics of responders; the author concludes.
