Management of Metastatic Clear Cell Renal Cell Carcinoma: ASCO Guideline.

PURPOSE: To provide recommendations for the management of patients with metastatic clear cell renal cell carcinoma (ccRCC). METHODS: An Expert Panel conducted a systematic literature review to obtain evidence to guide treatment recommendations. RESULTS: The panel considered peer-reviewed reports published in English. RECOMMENDATIONS: The diagnosis of metastatic ccRCC should be made using tissue biopsy of the primary tumor or a metastatic site with the inclusion of markers and/or stains to support the diagnosis. The International Metastatic RCC Database Consortium risk criteria should be used to inform treatment. Cytoreductive nephrectomy may be offered to select patients with kidney-in-place and favorable- or intermediate-risk disease. For those who have already had a nephrectomy, an initial period of active surveillance may be offered if they are asymptomatic with a low burden of disease. Patients with favorable-risk disease who need systemic therapy may be offered an immune checkpoint inhibitor (ICI) in combination with a vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor (TKI); patients with intermediate or poor risk should be offered a doublet regimen (no recommendation was provided between ICIs or an ICI in combination with a VEGFR TKI). For select patients, monotherapy with either an ICI or a VEGFR TKI may be offered on the basis of comorbidities. Interleukin-2 remains an option, although selection criteria could not be identified. Recommendations are also provided for second- and subsequent-line therapy as well as the treatment of bone metastases, brain metastases, or the presence of sarcomatoid features. Participation in clinical trials is highly encouraged for patients with metastatic ccRCC.Additional information is available at www.asco.org/genitourinary-cancer-guidelines.

Bone Health and Bone-Targeted Therapies for Prostate Cancer: ASCO Endorsement of a Cancer Care Ontario Guideline.

PURPOSE: In 2017, Cancer Care Ontario's Program in Evidence-Based Care released the Bone Health and Bone-Targeted Therapies for Prostate Cancer guideline. This guideline included recommendations across a relatively broad clinical spectrum within prostate cancer. Topics addressed ranged from management of osteoporotic fracture risk in nonmetastatic disease to management of men with castration-resistant prostate cancer metastatic to bone. ASCO has a policy and set of procedures for endorsing clinical practice guidelines that have been developed by other professional organizations. METHODS: The Bone Health and Bone-Targeted Therapies for Prostate Cancer guideline was reviewed for developmental rigor by methodologists. An ASCO Expert Panel then reviewed the content and the recommendations. RESULTS: The ASCO Expert Panel determined that the recommendations from the Bone Health and Bone-Targeted Therapies for Prostate Cancer guideline were clear, thorough, and based on the most relevant scientific evidence. ASCO wholly endorses the Bone Health and Bone-Targeted Therapies for Prostate Cancer guideline. RECOMMENDATIONS: The ASCO Expert Panel endorses all the original guideline recommendations as written and offers a series of discussion points to guide practice for clinicians as they manage bone-related risks within this patient population.

Development of Treatments for Localized Prostate Cancer in Patients Eligible for Active Surveillance: U.S. Food and Drug Administration Oncology Center of Excellence Public Workshop.

PURPOSE: The following is a summary of discussion at a United States FDA (Food and Drug Administration) public workshop reviewing potential trial designs and end points to develop therapies to treat localized prostate cancer. MATERIALS AND METHODS: The workshop focused on the challenge that drug and device development to treat localized prostate cancer has been limited by the large trial sizes and lengthy timelines required to demonstrate an improvement in overall or metastasis-free survival and by the lack of agreed on alternative end points. Additionally, evolving treatment paradigms in the management of localized prostate cancer include the widespread use of active surveillance of patients with low and some intermediate risk prostate cancer, and the availability of advances in imaging and genomics. RESULTS: The workshop addressed issues related to trial design in this setting. Attendees discussed several potential novel end points such as a delay of morbidity due to radiation or prostatectomy and pathological end points such as Gleason Grade Group upgrade. CONCLUSIONS: The workshop provided an open forum for multiple stakeholder engagement to advance the development of effective treatment options for men with localized prostate cancer.

Clinically Localized Prostate Cancer: ASCO Clinical Practice Guideline Endorsement of an American Urological Association/American Society for Radiation Oncology/Society of Urologic Oncology Guideline.

PURPOSE: In April 2017, the American Urological Association, American Society for Radiation Oncology, and Society of Urologic Oncology released a joint evidence-based practice guideline on clinically localized prostate cancer. The American Society of Clinical Oncology (ASCO) has a policy and set of procedures for endorsing clinical practice guidelines that have been developed by other professional organizations. METHODS: The Clinically Localized Prostate Cancer guideline was reviewed for developmental rigor by methodologists. An ASCO Expert Panel then reviewed the content and the recommendations. RESULTS: The ASCO Expert Panel determined that the recommendations from the Clinically Localized Prostate Cancer guideline were clear, thorough, and based upon the most relevant scientific evidence. ASCO endorsed the Clinically Localized Prostate Cancer guideline except for two recommendations on cryosurgery. The two recommendations covering cryosurgery were not endorsed because the panel found that there is insufficient evidence to support the use of cryotherapy in this setting. RECOMMENDATIONS: The ASCO Expert Panel endorsed all but two of the original guideline recommendations as written and offered a series of discussion points to guide practice.
