recurrent metastatic squamous neck cancer with occult primary

Retrospective observational study that aims to collect real world data on the cetuximab plus paclitaxel regimen as first line treatment for recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN).
Assignment of a patient to a specific therapeutic strategy has been already decided in the past according to normal routine clinical practice; the decision to prescribe a specific treatment (between January 2012 and December 2018) was clearly dissociated from the decision to include a patient in the present study.
The investigators will retrospectively collect the information for 500 patients diagnosed with recurrent and/or metastatic SCCHN treated with a cetuximab plus paclitaxel regimen as first line for unresectable recurrent and/or metastatic disease, starting treatment with the defined cetuximab plus paclitaxel regimen, in 20 hospital members of the "Grupo Español de Tratamiento de Tumores de Cabeza y Cuello (TTCC)", who express consent to participate in the study or have not explicitly withheld consent for use of their data. The information from the patients' medical records will be collected through the online database of the TTCC Group.

To evaluate safety, immunogenicity and anti-tumor responses of intradermally delivered SNS-301 added to checkpoint inhibitor therapy in locally advanced unresectable or metastatic/recurrent squamous cell carcinoma of the head and neck (SCCHN) patients.

The primary objective of the phase II trial is to determine the efficacy and safety of a combination of Durvalumab with the Carboplatin/Paclitaxel as first line treatment in patients with recurrent/metastatic SCCHN not eligible to standard chemotherapy.
