ASCO Adds New Combos for Metastatic Noncastrate Prostate Cancer

Use of androgen deprivation therapy (ADT) in combination with docetaxel (Taxotere) or abiraterone (Zytiga) in newly diagnosed cases of metastatic noncastrate prostate cancer (mNCPC) is recommended in recently updated American Society of Clinical Oncology (ASCO) guidelines. Historically, mNCPC has been treated with ADT alone until progression; ASCO noted a survival benefit from adding docetaxel or abiraterone, based on a review of several trials.1

For patients with low-volume disease (according to CHAARTED) who are candidates for chemotherapy, the guidelines moderately recommend offering docetaxel (Table).

Treatment Recommendations for De Novo Noncastrate Disease
The dosage of docetaxel alone or with prednisone is now listed as 6 doses at 75 mg/m2 administered every 3 weeks under a strong recommendation, based on both CHAARTED and STAMPEDE.1

The guidelines note that without randomized data comparing docetaxel with aberaterone, variables such as comorbidities, toxicity, quality of life, drug availability, and cost will need to be considered when choosing either treatment for a patient.
