Univariate analyses showed significant associations of unfavourable OS were multinodularity (>3) (p < 0.001), main tumor size (≥3 cm) (p = 0.023), blood loss (≥300 cc) (p = 0.003), CEA level (≥20 ng/ml) (p = 0.046) and platelet count (p = 0.016). The gene discussed is CEACAM5; the disease is neoplasm.
