Treatment Options in Oncology.

Multiple treatment strategies exist for many oncologic problems. In this review, we provide a summary of various reasons for the existence of multiple treatment options in oncology, including factors that concern the treating physician (eg, treatment preferences), environmental factors (eg, financial, regulatory, and scientific aspects), and individual patient-specific factors (eg, medical condition, preferences). We demonstrate the vital role of available treatment options and their origins for clinical decision making and patient communication. These aspects are particularly helpful in the process of shared decision making, which is increasingly favored in situations where there are multiple medically reasonable options.
