A minority of cases are inoperable at presentation, recur or develop metastatic disease with a historical 5\u2010year overall survival of ~10%. Treatment options in this setting are generally palliative. Immunotherapy has emerged as a new paradigm in managing these patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Patients presenting to Sydney West Cancer Network with locally advanced or metastatic CSCC treated with the anti\u2010PD1 agent cemiplimab were identified. Response to treatment was objectively assessed based on RECIST1.1 or PERCIST criteria. Primary end point was objective response rate (ORR). Secondary end points included progression\u2010free survival (PFS), overall survival (OS), therapy toxicity, and predictors of treatment response.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 19 patients were identified with a median age of 76 (range 56\u201394) and 4 immunosuppressed. The longest follow up duration was 28\u2009months. ORR, complete response (CR), and partial response (PR) were 68% (13\/19), 53% (10\/19), and 16% (3\/19), respectively. Median PFS was 12\u2009months (95% CI 9\u201314) whilst median OS was not reached by end of study. Responders (CR or PR) had significantly superior OS compared to those with no response (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.01).
