Disease-related Outcomes: subanalyses: 2A) All studies excluding those with mostly clear cases (surgery alone=24, surgery and adjuvant radiotherapy=10). 2B) studies with R0 cases only (surgery alone=16, surgery and adjuvant radiotherapy=6). 2C) studies with R0 + unknown margin status cases (surgery alone=24, surgery and adjuvant radiotherapy= 9). 2D) studies that did not include any cases of sentinel lymph node biopsy (SLNB) (surgery alone=24, surgery and adjuvant radiotherapy=11).
