Treatment
The primary advanced skin cancer surgery was total resection with flap reconstruction: 48.6%; exenteration: 13.5%; temporalectomy: 13.5%; rhinectomy: 5.4% (Table 1) . Histological differentiation was classified as follows: well, 35.1%; moderate, 43.2%; and poor, 21.6%. The surgical margins were compromised in 29.7% (Table 2) .
The overall incidence of neck metastasis was 32.4%: 51.4% in PM group and 13.5% in WPM group. Of these, 22.9% showed positive neck extracapsular spread. The type of neck dissection was selective (45.9%), modified radical (37.8%), or classic radical (8.1%) (Tables 1 and 2) .
The overall incidence of parotid metastasis was 50.0%; partial parotidectomy was done as follows: PM: 43.2% and WPM: 29.7%, total parotidectomy: PM: 54.1% and WPM: 10.8%. The parotid P stage was in PM group: P1 (54.1%), P2 (43.2%), P3 (2.7%); in WPM group: P1: 0%, P2 (2.7%), P3 (0%) (Table 2) . Overall parotid metastasis extracapsular spread was present in 32.4%, the PM group showed total parotidectomy: 54.1%, positive ECE: 35.1%, compromised margins: 29.7%; and partial parotidectomy: 43,2%, positive ECE: 27.0%, compromised margins: 24.3%.
The N stage was N0 (60.8%), N1 (18.9%), N2 (20.2%). Of these, 22.9% of the patients presented with lymph node extracapsular spread.
Adjuvant treatment was administered to 72.9%; 62.1% underwent external radiotherapy alone, none have received braquitherapy; while 18.9% received chemoradiotherapy (Table 1) .
