NCCN Guidelines® Insights - Merkel Cell Carcinoma, Version 1.2024
The NCCN Guidelines for Merkel Cell Carcinoma (MCC) provide recommendations for diagnostic workup, clinical stage, and treatment options for patients. The panel meets annually to discuss updates to the guidelines based on comments from expert review from panel members, institutional review, as well as submissions from within NCCN and external organizations. These NCCN Guidelines Insights focus on the introduction of a new page for locally advanced disease in the setting of clinical node negative status, entitled “Clinical N0 Disease, Locally Advanced MCC.” This new algorithm page addresses locally advanced disease, and the panel clarifies the meaning behind the term “nonsurgical” by further defining locally advanced disease. In addition, the guideline includes the management of in-transit disease and updates to the systemic therapy options.
This journal article is designed to meet the educational needs of oncologists, nurses, pharmacists, and other health care professionals who manage patients with cancer.
Upon completion of this activity, participants will be able to:
- Integrate into professional practice the updates to NCCN Guidelines for Merkel Cell Carcinoma.
- Describe the rationale behind the decision-making process for developing the NCCN Guidelines for Merkel Cell Carcinoma.
NCCN Continuing Education Disclosure Policy
It is the policy of NCCN that all planners, faculty, moderators, authors, reviewers and anyone involved in the planning and delivery of NCCN continuing education activities are expected to disclose ALL financial relationships they have had in the past 24 months with ineligible companies. The ACCME Standards for Integrity and Independence require that individuals who refuse to provide this information will be disqualified from involvement in the planning and implementation of accredited continuing education presented by NCCN. NCCN identifies, mitigates and discloses to learners all relevant financial relationships.
In addition, all content has been reviewed to ensure education promotes safe, effective patient care and does not promote the products or services of an ineligible company. Content, including any presentation of therapeutic options, is fair, balanced, evidence-based, scientifically accurate, and free of commercial bias and marketing.
Ineligible Company: An ineligible company is any entity whose primary business is producing, marketing, selling, re-selling, or distributing healthcare products used by or on patients.
Relevant Financial Relationships: Financial relationships of any dollar amount occurring within the past 24 months are defined as relevant if the educational content an individual can control is related to the business lines or products of an ineligible company. There is no minimum financial threshold. We ask for disclosure of ALL financial relationships with ineligible companies, regardless of the amount and regardless of the potential relevance of each relationship to the education.
All faculty for this continuing education activity are competent in the subject matter and qualified by experience, training, and/or preparation for the tasks and methods of delivery.
