简要总结
Squamous Cell Carcinoma (SCC) is one of the most common malignancies in caucasian population. The effect of the immune system on the development of skin tumors has been demonstrated in transplant patients taking immunosuppressive agents (65 fold risk increase). It has been reported that activation of EGFR and RAS signaling pathways play an important role in disease progression maybe through downregulation of the immune system.
The investigators want to treat unresectable SCC patients with an antibody against EGFR (Vectibix®, panitumumab). This antibody induces tumor regression in metastatic colorectal cancer and has been approved as single agent for this indication.
The investigators want to measure the response rate but also analyze the modification of expression profile of some key proteins involved or supposed to be involved in the signaling pathways of EGFR and in the regulation of the immune system. Chemokines such as CCL27 have been shown to play a critical role in the skin-associated immune response by regulating T cell homing. Pivarcsi et al have reported that downregulation of CCL27 is mediated by activation of EGFR/RAS/MAPK signaling pathways.
详细描述
This is an open-label, multicentric study of 17 patients with skin squamous cancer cell.
Eligible patients should not be suitable for immediate surgery. If they have only one tumor, it should be greater than 3 cm2 in order to allow multiple biopsies.
Patients will receive six infusions of Panitumumab 6 mg/kg every 2 weeks or until progression if earlier.
Patients will be assessed at baseline, at week 6 and then every 12 weeks till progression. In addition to clinical examination, evaluation tools will include photography and CT-scan, MRI or PET-scan.
Skin and tumor biopsies will be performed during first cycle at baseline and at days 2, 4, 8, 43, 85. Blood collections for translational research will be done during first cycle at baseline and at days 2, 4, 8,15, 43, 85. Blood collection for hematology and chemistry assessment will be done each 4weeks.

研究组 & 干预措施
panitumumab
Patients will receive six infusions of panitumumab every 2 weeks for the first cycle.
干预措施: infusions of Panitumumab (Drug)
结局指标
主要结局
Overall Response Rate (ORR)
时间窗: via imaging every 12 weeks
To measure the efficacy of Panitumumab for SCC in terms of Overall Response Rate (ORR). Overall Response Rate (ORR) is defined as the sum of complete and partial tumour responses seen, divided by the total number of evaluable patients.
次要结局
- To assess the safety profile of panitumumab in SCC(at each visit)
- Time to treatment failure (TTF)and Time to treatment progression TTP(via imaging, every 12 weeks)
- To measure the duration of response.(via imaging, every 12 weeks)
- To explore the gene expression profiles in SCC under panitumumab treatment (i.e CCL27, EGFR,…).(Skin and tumor biopsies will be performed at baseline and at days 2, 4, 8, 43, 85. Blood will be collected at baseline and at days 2, 4, 8, 43, 85)
