Multidisciplinary Management of Locally Advanced and Metastatic Cutaneous Squamous Cell Carcinoma

Non-melanoma skin cancers are the most prevalent form of cancer, with cutaneous squamous cell carcinoma (cSCC) being the 2nd most common type. Patients presenting with high-risk lesions associated with locally advanced or metastatic cSCC face high rates of recurrence and mortality. Accurate staging and risk stratification for patients can be challenging because no system is universally accepted, and no Canadian guidelines currently exist. Patients with advanced cSCC are often deemed ineligible for either or both of curative surgery and radiation therapy (RT) and, until recently, were limited to off-label systemic cisplatin–fluorouracil or cetuximab therapy, which offers modest clinical benefits and potentially severe toxicity. A new systemic therapy, cemiplimab, has been approved for the treatment of locally advanced and metastatic cSCC. In the present review, we provide recommendations for patient classification and staging based on current guidelines, direction for determining patient eligibility for surgery and RT, and an overview of the available systemic treatment options for advanced cSCC and of the benefits of a multidisciplinary approach to patient management

Development of a core outcome set for cutaneous squamous cell carcinoma trials: identification of core domains and outcomes

Background: The lack of uniformity in the outcomes reported in clinical studies of the treatment of cutaneous squamous cell carcinoma (cSCC) complicates efforts to compare treatment effectiveness across trials. Objectives: To develop a core outcome set (COS), a minimum set of agreed-upon outcomes to be measured in all clinical trials of a given disease or outcome, for the treatment of cSCC. Methods: One hundred and nine outcomes were identified via a systematic literature review and interviews with 28 stakeholders. After consolidation of this long list, 55 candidate outcomes were rated by 19 physician and 10 patient stakeholders, in two rounds of Delphi exercises. Outcomes scored ‘critically important’ (score of 7, 8 or 9) by ≥ 70% of patients and ≥ 70% of physicians were provisionally included. At the consensus meeting, after discussion and voting of 44 international experts and patients, the provisional list was reduced to a final core set, for which consensus was achieved among all meeting participants. Results: A core set of seven outcomes was finalized at the consensus meeting: (i) serious or persistent adverse events, (ii) patient-reported quality of life, (iii) complete response, (iv) partial response, (v) recurrence-free survival, (vi) progression-free survival and (vii) disease-specific survival. Conclusions: In order to increase the comparability of results across trials and to reduce selective reporting bias, cSCC researchers should consider reporting these core outcomes. Further work needs to be performed to identify the measures that should be reported for each of these outcomes
