CME / AMA PRA Category 1 Credit™
Most cases of cutaneous squamous cell carcinoma (cSCC), a common cancer, are recognized early and treated successfully with surgery. A small percentage of patients develop advanced or metastatic disease, in which case data to guide treatments are sparse and management depends on a patient’s level of disability and comorbidities. Because patients with de novo or post-surgical advanced or metastatic cSCC are rare, oncologists aren’t always acquainted with pathophysiology, recommendations for diagnostic evaluations, disease staging, management strategies, or agents in clinical trials. Research is contributing to a greater understanding of tumor molecular markers (e.g. overexpression of EGFR) and the role of the programmed death-1 (PD-1) pathway, and has led to the use of targeted agents and the first FDA-approved agent (a PD-1 inhibitor) to treat advanced and metastatic cSCC.
This activity will help clinicians recognize and thoroughly evaluate and stage patients with cSCC who are at high risk of advanced or metastatic disease. Participants should then be able to use this information, in conjunction with expert recommendations and the multidisciplinary team, to develop treatment plans. Up-to-date knowledge of cSCC pathophysiology, including the role of mutations, EGFR overexpression, and the immune system, will give clinicians an understanding of where newly approved and in-development agents fit in treatment strategies.
Welcome and Introductions
Staging of cSCC
Current Understanding of the Pathophysiology of Advanced/Metastatic cSCC
Evolving Paradigm for Managing Advanced/Metastatic cSCC
This activity is intended for oncologists, oncology nurses, pharmacists, and other healthcare professionals involved in the treatment and care of patients with cSCC.
This program is designed to address ACGME and NAM competencies, including delivering patient-centered care and practicing evidence-based medicine.
At the conclusion of this activity, participants should be able to:
Outline the diagnostic evaluation of patients with cSCC
Describe commonly used systems for staging cSCC
Review the current understanding of the pathophysiology of advanced and metastatic cSCC
Review current recommendations for developing individualized management plans for advanced and metastatic cSCC, including the need for a multidisciplinary team
Describe the efficacy and safety of immune-targeted agents newly approved for the management of cSCC
This activity has been planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of USF Health and Rockpointe. USF Health is accredited by the ACCME to provide continuing medical education for physicians.
USF Health designates this enduring material for a maximum of 1.0 AMA PRA Category 1 Credit™. Physicians should only claim credit commensurate with the extent of their participation in the activity.

I’d like to begin the talk by reviewing the epidemiology and incidents of cutaneous squamous-cell carcinoma in the United States. Cutaneous squamous-cell carcinoma is the second most common cancer in our country. It’s second after basal cell carcinoma. In fact, newer incidents estimates are found at the number of cutaneous squamous-cell carcinomas diagnosed each year is almost the same as that of basal cells. This is primarily due to arising incidents with an increase of over 250% from the 1980s to the 2000s. Squamous-cell carcinoma is not captured in National Cancer registries. However, it is estimated that approximately one million tumors are treated each year. While most tumors have an excellent prognosis and are cured with surgery alone, a small subset will develop a poor outcome. Approximately 5% of tumors will develop a local recurrence, 4% will develop a nodal metastasis and 2% of patients will die from their disease.
Slide 6 – Risk Factors for and Staging of cSCC
Since cutaneous squamous-cell carcinomas are so common, it is important to risk-stratify tumors, so that we can identify those at risk for poor outcomes. There are certain risk factors that increase poor outcomes. Some are used as part of the current primary tumor staging systems.
Slide 7 – Risk Factors for Local Recurrence and Metastases
Important tumor risk factors can be divided into anatomic and histologic features. In the coming slides, I will review the different risk factors listed on this slide.
Slide 8 – Anatomic Risk Factors
Tumor diameter has been shown to increase both recurrence, metastasis and death from disease. Tumors above 2 cm have a three times of recurrence, six times risk of metastasis, and 19 times increase in disease-specific death. The NCCN guidelines categorize a number of locations as high risk, although it is important to note that the current primary tumor staging systems do not consider location as a risk factor. Studies have shown, however, that tumors on the ear and lip have a 1.3 times risk of local recurrence, 2.3 times risk of metastases, and over 4.5 times risk of disease-related death.
