Table 2 (c)–(f) shows the multivariate models for resected cancers. The initial model (Table 2, c) was subjected to stepwise removal of redundant variables to Table 2 (e), where LMO4 expression became the only independent prognostic factor. Removal of margin status demonstrated that LMO4 expression was independent of lymph node involvement (Table 2, f); however, LMO4 expression was not independent of margin involvement by the tumour (Table 2, g). Here, LMO4 is linked to cancer.
