Breuninger et al used a staging system for cutaneous squamous cell carcinoma. This can help to identify a patient who has an increased risk of metastases. The authors are from Tuebingen University Hospital in Germany.
Patient selection: cutaneous squamous cell carcinoma.
Parameters associated with metastases:
(1) clinical tumor stage based on tumor diameter in cm (cT)
(2) pathological tumor stage based on tumor thickness in mm (pT)
(3) co-risk factors
Tumor Diameter
Risk of Metastases
<= 2 cm
low
> 2 cm
high
Tumor Thickness
<= 2 mm
none
2.01 to 6 mm
> 6 mm
Co-risk factors:
(1) immunosuppression
(2) poorly differentiated (high grade) or desmoplastic on histology
(3) located on the ear
