Primary objectives:
1\. Monitor cancer-specific outcomes of men who meet consensus criteria for active surveillance under one of three categories: 1) low or very low-risk prostate cancer, 2) intermediate risk with patient consent, or 3) severe medical comorbidities and high-risk localized prostate cancer or patient desire, despite recommendation
Secondary objectives:
1. Screen for a relationship between cancer-specific and clinical outcomes related to selected comorbidities.
2. Determine the feasibility of electronically facilitated symptoms and disease monitoring to guide therapeutic intervention and prompt therapeutic course correction.
3. Develop a tissue and data resource to support discovery and hypothesis generation focused on germline alterations, somatic alterations, and/or the interaction between the two in determining cancer-specific and overall outcomes
