| Popis: | 9090 Background: With an increasing aging population and a growing number of people with organ transplant on immune suppression, patients presenting with locally advanced, unresectable and metastatic SCCS are on the rise. Options of therapy are limited to platinum or taxane doublets but the tolerability of these regimens is poor. Data regarding use of cetuximab in advanced SCCS is scarce and consists of a few case series and one phase II trial. The purpose of this study is to evaluate the use of cetuximab alone or in combination with chemotherapy in patients with SCCS treated at the University of Iowa Hospitals (UIHC). Methods: Patient data was compiled through medical record review of all patients diagnosed with locally recurrent, unresectable or metastatic SCCS seen at UIHC and treated with cetuximab alone or in combination with chemotherapy. Pathology was centrally reviewed. Results: A total of nine patients with SCCS received cetuximab as part of a definitive or palliative therapy with a loading dose of 400 mg/m2 followed by weekly 250mg /m2.Median age of patients is 64. Four patients had locally recurrent or unresectable disease, and five had distant metastases. Three patients had prior history of organ transplant. Chemotherapy included carboplatin AUC 5 with 5 fluorouracil 1000mg/m2/day for four days in two patients and weekly paclitaxel 80mg/m2 in four patients. One patient received concurrent definitive radiation with 6600 cGy. In total, six patients completed at least 6 weeks of cetuximab. All these patients showed clinical improvement in pain, tumor ulcer and bleeding as compared to pretreatment. Median time to disease progression after stopping treatment was 3 months. Three patients could not complete 6 weeks of cetuximab due to disease progression. The most common side effect was skin rash and hypomagnesemia. Conclusions: Cetuximab alone or in combination with chemotherapy is well tolerated and does show promise in treatment of patients with unresectable or metastatic SCCS. Most common side effect was skin rash. A larger trial with longer follow up is warranted to establish the role of cetuximab and an optimal combination therapy in improving quality of life in this patient population. |
