On univariate survival analysis (Table 3), age (P<0.10), tumour size (P<0.10), lymph node involvement (P<0.05), albumin (P<0.01), microvessel density CD34+ (P<0.10), locoregional treatment (P<0.01) and systemic treatment (P<0.10) were significantly associated with overall survival. Here, CD34 is linked to neoplasm.
